Patented Aug. 8, 1961 l ce 2 995 127 PRESSURIZED SPRAY? AiPLICATOR ARRANGE- MENT FOR ENGINE MANIFQLDS Charles P. Orr, Camden, N..l., assignor to Spray Products My invention relates broadly to engines of the diesel and gasoline type and more particularly to a structure of compartmented manifold for receiving and utilizing a starting fluid contained in a pressurized can.

This application is a continuation in part of my copending application, Serial No. 522,199 filed July 15, 1955, for Fuel Atomizing Spray Device, now Patent 2,860,009, dated November 11, 1958.

One of the objects of my invention is to provide a construction of compartmented manifold for engines into which a pressurized can of starting fluid may be readily inserted and the valve of the pressurized can actuated from time to time to supply a spray of atomized starting fluid into the engine manifold when conditions require this aid in starting the engine.

Another object of my invention is to provide an arrangement of engine starting equipment where the manifold of the engine is provided with an integrally connected chamber of a size into which a standard pressurized can of starting fluid may be readily inserted and removed in a position in which the spray valve of the pressurized can is readily operated for spraying starting fluid into the engine manifold from time to time under control of the operator.

Another object of my invention is to provide a construction of compartmented manifold for engines into which the pressurized can of starting fluid may be inserted, removed, and renewed and wherein the pressurized can is selectively displaceable for effecting an actuation of the spray valve thereof for spraying atomized starting fluid into the manifold.

A further object of my invention is to provide a compartmented manifold for engines including means for fixing a pressurized can of starting fluid therein in association with means for selectively depressing the spray valve on the can for directing a spray of atomized starting fluid into the engine manifold.

A still further object of my invention is to provide a compartmented manifold for engines into which a pressurized can of starting fluid may be inserted with the spray valve thereof positioned immediately adjacent the flow path of fuel in the manifold of the engine and the valve of the pressurized can selectively actuated for delivering atomized starting fluid into the fuel flow path of the manifold with means for monitoring the valve operation to enable the operator to be informed at all times that the starting fluid is being sprayed into the manifold.

Another object of my invention is to provide an arrangement of hydraulically controlled means for operating the spray valve of a pressurized can of starting fluid for effecting delivery of an atomized spray of starting fluid into the manifold of an engine, the hydraulic means being conveniently controllable from an operators posinon.

Still another object of my invention is to provide a construction of an electrical switch operative under control of a monitored portion of the spray from the spray valve of a pressurized can located in the area of the engine manifold by which the condition of spray emanating from the spray valve may be observed by the operator at all times.

Another object of my invention is to provide a construction of a thermally controlled electrical switch in the intake manifold of an engine operative in association with the spray valve of a pressurized can of starting fluid for indicating to the operator the condition of the spray within the engine manifold which would otherwise be unobservable to the operator, particularly where the contents of the pressurized can may have become exhausted and a replacement can may be required.

My invention is directed to the effective utilization of atomized starting fluid for starting diesel and gasoline engines under adverse conditions. I provide an engine manifold which contains a chamber or compartment into which a standard pressurized can of starting fluid may be readily inserted and renewed from time to time. I arrange the pressurized can within the chamber or compartment with the spray valve thereof directed toward the fuel flow portion of the engine manifold and provide means for either mechanically or hydraulically depressing the valve of the pressurized can for delivery of an atomized spray of starting fluid into the fuel flow path in the manifold or I mount the pressurized. can so that it is capable of slight translatory displacement longitudinally of the chamber or compartment through a sufficient distance to effect actuation of the spray valve for delivering an atomized spray to the fuel flow portion of the engine manifold. The compartment or chamber is provided with closure means which may be readily opened and closed to permit the entry of a pressurized can of starting fluid. Inasmuch as the compartment or chamber when closed precludes any observation of the condition of the starting fluid in the pressurized can I provide special means for indicating the operative condition of the atomized spray. Under certain circumstances I may employ a pressure actuated switch which is operated by a monitored portion of the atomized spray to electrically indicate the condition of operation of the atomized spray in the fuel flow portion of the manifold. Under other conditions I employ a thermally controlled switch located in the fuel flow portion of the engine manifold and subject to the spray of the atomized starting fluid. Upon failure of the atomized spray of starting fluid the temperature cont-rolled switch operates to warn through an indicator the operator of the fact that the pressurized can of starting fluid is empty and must be replaced.

Under certain conditions I prefer to construct the engine manifold in two sections where the compartment or chamber for the pressurized can of starting fluid terminates in a flange which may be bolted to a coacting flange on the fuel flow portion of the manifold in which case the chamber or compartment for the pressurized can of starting fluid is not integral with the fuel flow portion of the manifold thus facilitating manufacture.

Referring to the drawings in more detail, the manifold is'represented by reference character 1, while reference character 2 represents the starting fluid pressurized can holder protrusion from the manifold. Pressurized can 3, containing the starting fluid, is held in holder 2 by end cap 4 sealed with respect to the holder by gasket 5 and clamping mechanism 6. To hold the can firmly in place and prevent it from vibrating or rattling, spring 7 is attached to a grooved raised portion shown at 8 on the interior face of end cap 4 in such a manner as to compress against the bottom surface of the can when the end cap is clamped in position as shown in FIGS. 3 and 9.

The clamping mechanism 6 can be comprised of any suitable clamping means and not necessarily restricted to the form or type shown in the drawings. In the clamping mechanism shown in the drawings, clamp bar 9 is fitted into a groove shown at 10 on the exterior end surface of end cap 4, while the terminating ends thereof are pivoted in handle member 1 1 as shown at 12. Handle member 11 is pivoted in turn in protrusions from the holder 2 as shown at 13 and '14. The pivot points 12 of clamp bar 9 in handle member 11 are olf-center with respect to the pivot points of handle member 11 in such a manner that clamp bar 9 is locked in groove 10 when handle member 11 is pulled toward the rear of holder 2, as seen in FIGS. 1, 2, 3 and 9, and when handle member 11 is pushed toward the front of the holder, clamp bar 9 is unlocked from groove -10 since its pivot points 12 are moved toward the rear of the end cap and the bar 9 is positioned into a free swinging state as shown in FIG. 5 to permit removal of can 3 from the holder or manifold compartment.

The bottom rim 15 of the can is engaged by spring hooks 16 when end cap 4 is in position, as shown in FIGS. 3 and 9. Spring hooks 16 are fastened to movable guide ring 17 which is spring-loaded by spring 19 in groove 18 on the interior surface of holder 2. Guide ring 17 carries an outwardly protruding fulcrum stud 20 on each side thereof which extends through longitudinal slots 21 in the sidewalls of holder 2. These longitudinal slots 21 are fitted with yieldable gaskets 22 sealed in said slots and around studs 20. The slots 21 are further sealed from entry of foreign material from the exterior thereof by cover members 23 secured to holder 2 and containing slots 29 therein to allow free longitudinal movement of t-f d studs 20. The cover members also aid in maintaining gaskets 22 in slots 21 and also act as hearing plates for the arms of lever 24. Lever 24, of substantially T-shaped construction, pivoted about protrusion 14 by pivot bolt 25, provides openings 26 in the ends of the T cross-arm for engaging studs 20. A cable 27 is attached to the end of the main body member of the T-shaped lever 24 as shown at 28, such that, when a pulling force is applied to said cable, lever 24 pivots slightly about protrusion 14 in such manner as to apply a force to studs 20 which causes said studs, guide ring 17, connected spring hooks 16, and associated can 3 to move toward the right as viewed in FIGS. 1, 2, 3 and 9. As this action occurs guide ring -17 compresses spring 19 in slot 18 as spring hooks 16 move can 3 toward the right while spring 7 associated with end cap 4 is allowed to expand slightly. The entire movement of lever 24 is very slight, that is, lever 24 pivots just enough to impart a forward movement to can 3 through a distance of approximately ,4 inch. The actuated position of the spray applicator showing the can moved to the forward position is shown in FIG. 8 while FIG. 3 shows the can in the normal unactuated position.

The top of can 3 carries a depressible discharge valve 30 and top rim shown at 31. When the starting fluid spray can 3 is in position in holder 2 the depressible dis charge valve 30 is engaged in and abuts nipple-discharge member 32 which protrudes through the manifold wall separating the intake manifold cavity from the can holder compartment or cavity. The portion of the nipple-discharge member 32 on the can side of the partitioning manifold wall is situated in a cavity designated at 33 of smaller diameter than the can holder cavity. Conicalshaped spring members 34 and 35 and movable preloaded disc 36 are disposed in this cavity about nipple-discharge member 32 such that said conical spring members are compressible between the manifold partitioning wall and said preloaded disc 36. Preloaded disc 36, spring-loaded by conical-shaped spring members 34 and 35, is held in cavity 33 in this spring-loaded state by retainer ring 37 fastened by bolts 38 to the manifold partitioning wall. In the normal inactivated state nm 31 of can 3 projects through the center of retainer ring 37 and bears on the surface of preloaded disc 36 as shown in FIG. 3.

When can 3 is moved into the actuated position as shown in FIG. 9, rim 31 of can 3 moves preloaded disc 36 out of contact with retainer ring 37, thus compressing conical-shaped spring members 34 and 35. Since nippledischarge member 32 is stationary and discharge valve 30 is depressible, as can 3 is moved into the actuated position, valve 30 is depressed into pressurized can 3 thus releasing, from pressurized can 3 into intake manifold 1, an atomized spray of starting fluid through discharge passage 39 of nipple-discharging member 32. As shown in FIG. the end of discharge passage 39 is upwardly directed to act as a nozzle for distributing the atomized starting fluid spray throughout the intake manifold cavity.

The cable 27 by which the starting fluid applicator is actuated extends into the interior of the vehicle and is conveniently mounted within easy reach of the operator as, for example, a pull-knob on the dashboard. If the applicator is mounted on other than a vehicle the actuating cable, terminating in a pull-knob, extends to within easy reach of the engine operator. In order that the operator may know that the spray applicator is functioning correctly and that atomized starting fluid is being discharged into the air intake manifold, I provide a signal light 40 connected into a battery circuit, as shown in FIG. 3, within sight of the operator which is energized by the closing of pressure switch 41 which in turn is operated by the increased pressure in the discharge passage 39 as atomized spray is discharged from the can. Nipple-discharge member 32 contains pressure switch bleed-off or monitoring passage 42 as a branch passage from discharge passage 39. Passage 42 aligns with the main pressure switch passage indicated at 43 leading to pressure switch cavity 44 into which is threaded pressure switch 41 as shown in FIG. 11. When the atomized vapor is released from pressurized can 3 the pressure in passages 39, 42 and 43 greatly increases. This increased pressure flexes diaphragm 45, held in position by washer 46, in an upward direction, thus moving plunger member 47, which is constructed of an electrically conductive material, in an upward direction, compressing spring 48 and bringing the end of plunger 47 into electrical contact with electric contact member 49 which is connected to one side of signal light 40. Electrical cont-act '49 is insulated from the body of the pressure switch by insulation block 50 into which it is threaded. A hole at one end thereof allows the end of plunger member '47 to move into electrical contact with said electric contact member 49. At all times plunger member 47 is in electrical contact with ground through sliding electrical contact with the pressure switch body as indicated at 51, through spring 48 to the pressure switch body and through the pressure switch body to the man-ifold itself which is grounded. Therefore this pressure switch is used to close the ground circuit to the signal lamp and the switch construction is such that should there be a spark on contact of plunger 47 with contact member 49 due to a potential difference, the spark chamber is well sealed from the starting fluid vapor in passage 43, by sliding contact fit indicated at 51 and by diaphragm 45, so that there is no danger of an explosion due to vapor ignition. The pressure switch as illustrated in FIG. 1'1 is shown in the normal de-energized state when the signal light is ofii.

The compression strengths of the various springs in the spray applicator are such that atomized spray ceases to be discharged from depressible discharge valve 30 immediately upon release of cable 27. Spring 19 exerts a force of such magnitude as to restore lever 24 to the normal position while spring 7 is of slightly less compression strength than are conical-shaped springs 34 and 35, so that can 3 can be immediately restored to its normal unaotuated position by the restoring forces of springs 34 and 35 immediately upon release of actuating cable 27. For example, if conical-shaped springs 34 and 35 were approximately ten pound springs then spring 7 would have a compression strength of approximately eight pounds.

FIG. 5 shows the manner in which the pressurized can 3 of starting fluid is inserted into or removed from the holder or compartment 2. The handle member 11 is moved to a position shown in FIG. 5 and the end cap 4 pushed inwardly against spring 7 releasing the clamp bar 9 from groove 10 whereupon end cap 4 may be removed as the clamp bar 9 is dropped downwardly. Upon removal of the end cap '4 the spring hook 16 releases the bottom rim 15 of can 3 as shown in FIG. 5 and can 3 is axially moved out of or inserted into the compartment or holder constituting the housing 2. Upon replacement of the pressurized can 3 with a fresh can the cap 4 is replaced on the holder 2, the clamp bar 9 fitted into groove 10 and the handle member 11 moved to the position shown in FIG. 1, whereupon the pressurized can 3 is securely confined within the holder or housing 2.

In FIGS. 12-17 I have shown a modified form of the integral manifold-starting fluid spray applicator of my invention wherein the housing or holder 2 is provided with an annular outwardly extending flange 52 thereon which serves as an annular seat for the sealing gasket 53 carried in the end cap 54. The end cap 54 has a central recess 55 therein in which there is mounted the resilient pad 56. This pad 56 has a central protrusion 57 therein which conforms with the inwardly extending bottom 58 of the pressurized can 3. A stud 59 is imbedded in the pad 56 and extends rearwardly therefrom and passes slidably through central aperture 60 in the end cap 54 and is engaged by the end 61 of the yoke 62 which is pivotally mounted at opposite ends at 63 and 64 on diametrically opposite sides of the exterior of housing or holder 2. The yoke 62 has an extension 65 on one end thereof forming an arm which constitutes a bell crank having a slot 67 in the end thereof for the engagement or disengagement of the hook 66 connected .to the control Wire 68 leading to the control operators position to facilitate connection and disconnection of the hook 66 from the slot 67 in the extension arm 65. I provide a latchable keeper 69 pivoted at 70 on arm 65 to enable the hook 66 to be readily engaged or disengaged from the slot 67 and when engaged, maintained in position. This requirement for disengagement of control wire 68 is necessary to permit the yoke 62 to be dropped down out of obstructing position with respect to the open end of the holder 2 so that the pressurized can 3 can be inserted into or removed from the holder.

The means for maintaining end cap 54 in engagement through gasket 53 against flange 52 consists of latching levers 71 and 72 pivoted at 73 and 74 at symmetrical positions on the opposite sides of bale 75 which is pivoted at 76 and 77 in diametrically opposite positions on the exterior of the holder or housing -2. The levers 71 and 72 have hook shaped ends which engage lugs 78 and 79 projeoting from opposite sides of the end cap 54. By raising the bale 75 to the position shown in FIG. the lovers 71 and 72 are moved to positions releasing the lugs 78 and 79 enabling the end cap 54 to be removed providing clear access for the insertion or removal of the pressurized can 3. Upon insertion of a fresh pressurized can of starting fluid in the holder 2 and the latching of cover 54 in position over the holder 2 and with the control wire 68 latched in position on the arm 65 of the bell crank, the spray device is ready for remote control from the operators position through a drawing force supplied on control wire 68.

In FIGS. 18, 19 and 21 I have shown a further modified form of my invention wherein the spray valve on the pressurized can within the holder 2 is actuated by hydraulic means. In this arrangement a tube 80 is supplied with hydraulic fluid which passes through a guide plug 81 intermediate the holder 2 and the fuel flow portion of the manifold shown at 1. The hydraulic tube 80 is stabilized by the flange 82 located between guide plug 81 and the cylindrical boss 83 where it terminates in a toroidal hollow gasket 84 of resilient material and which is filled with hydraulic fluid. When additional hydraulic fluid is forced through tube 80 into hollow gasket 84 this expands gasket 84 and operates to displace the circular disc 85 which is connected with the outside of the skirt of the nozzle 86. The interior of the intake end of the nozzle 86 is recessed to receive the stem of the depressible valve of the pressurized can 3 so that as the gasket 84 expands the disc 85 is displaced depressing valve stem 30 and allowing atomized starting fluid to be sprayed through bore 87 in nozzle 86 and into the fuel flow portion of the manifold 1 as hereinbefore explained in connection with the previous forms of my invention. The hollow recess 88 within which the gasket 84 operates has its open end closed by an annular plate 89 centrally apertured to permit the passage of the cylindrical end of the nozzle 86 and the free movement thereof. The plate 89 includes an annular recess 90 therein into which the rim 31 of the pressurized can 3 is adapted to be centered. A sealing gasket 91 is carried by pressurized can 3 surrounding the base of the stem of depressible valve 30 and establishes sealing contact with the annular portion 92 of plate 89 as shown. The plate 89 has a central outward projection 93 thereon which serves as a centening means for the compression coil spring 94 which maintains disc 85 in contact with resilient gasket 84. The strength of spring 94 is selected so that hydraulic fluid introduced into gasket 84 through tube 80 will build up to a pressure suflicient to overcome the strength of spring 94 and then depress valve 30. The nozzle 86 is slightly less in diameter than the bore 95 in the wall of the manifold 1 and as the hydraulic pressure builds up in gasket 84 nozzle 86 will be slightly retracted for a sufficient distance to effect movement of the spray valve in the pressurized can for directing an atomized spray of starting fluid into the fuel flow portion of manifold 1. The displacement of nozzle 86 is very slight and does not interfere with the distribution therefrom of the atomized spray into the fuel flow portion of manifold 1.

In order to facilitate the removal of empty pressurized can 3 and the replacement of a freshly stocked pressurized can I may employ the bayonet lock type of closure shown in FIG. 18 wherein the holder or housing 2 is provided with an enlarged end portion 96 having a bayonet thread 97 therein and serving as a seat for an annular gasket 98. In this form of my invention the end cover 99 is provided with a co-acting bayonet member 100- which in a slight twist will engage the bayonet thread 97 in the end portion 96 of the housing 2. A coiled spring 7 as heretofore explained engages the bottom 58 of the pressurized can 3 and extends from the center portion 101 of the cover 99 for urging pressurized can 3 into housing 2 in a position in which the annular rim 31 of can 3 enters the annular recess 90 in the plate 89. Thus the pressurized can 3 is maintained in fixed position while the spray valve 86 is moved by hydraulic pressure in gasket 84 for displacing disc 85 and actuating spray valve- 30 for directing the atomized spray into the fuel flow portion of manifold 1.

I have heretofore alluded to the precaution which I take in shielding any possible electric arcing at contacts from the highly volatile starting fluid where monitoring of the condition of operation of the spray valve is essential so that the operator will be put on notice that the spray valve is functioning and that there is no exhaustion of the contents of the pressurized can. In FIG. 20 I have shown a modified form of the electrical control for the monitoring system wherein a screw device '102 is passed through the wall of the fuel flow portion of the manifold 1 in a position immediately adjacent the atomizing nozzle 32 or 86. The screw device 102 serves as a support for a bimetallic strip indicated at 103 consisting of a pair of thin aluminum strips 104 and 105 separated by a strip of insulation material 106, the strips projecting into the path of the atomized spray from nozzle 86. The screw device 102 serves to support an axially extending electrode 107 terminating in an electrical contact 108 immediately adjacent the assembly of bimetallic strips. The electrode 107 is insulated from screw device 102 by means of sleeve 109 of insulation material terminating in a flange 110. The electrode 107 is screw threaded at the end thereof to receive the nut 111 to which an electrical conductor may be connected as represented at 112 forming one side of the control circuit to the contact 108. The other side of the control circuit connects to the bimetallic assembly of strips through the ground connection represented at 113. The strips 104 and 105 being located in the path of the atomized spray from nozzle 86 will be subject to change in position sufficient to control the movement of the bimetallic strips into contact with contact 108 depending upon whether or not the strip 104 is struck by the spray of atomized fuel. The atomized fuel by striking one of the strips changes the expansion characteristics thereof resulting in the displacement of the bimetallic strip assembly so that electrical contact is established between the bimetallic strip assembly and the contact 108 closing the circuit to the indicator lamp or an alarm as hereinbefore explained.

In the several forms of my invention I have referred to the integral relation between the holder or housing for the pressurized can and fuel flow portion of the manifold 1. It is not essential that the holder or housing for the pressurized can 3 be integrally connected with the fuel flow portion of manifold 1 and in FIG. 21 I have shown a modified form of my invention in which the housing 114 terminates in a flange 115 which co-acts with a complementary flange 116 on the fuel flow portion of the manifold which I have designated at 117. To facilitate the connection of the housing 114 to the manifold 117 I provide a circular recess 118 in flange 115 and a complementary circular projection 119 in the manifold 117. Bolts 120 and fastening nuts 121 are provided for securing flanges 115 and 116 together. In this arrangement the partition between the housing 114 and manifold 117 is somewhat wider than partitioning means in the other form of my invention and in this space I mount the monitoring switch of the type previously described and illustrated in FIG. 11 except that in the form of my invention shown in FIG. 21 I arrange a radially extending port 122 through which a short length of flexibly moulded tubing 123 extends. This tubing terminates at one end in a flange 124 located immediately adjacent the diaphragm and the electric circuit control assembly as explained in connection with FIG. 11. The other end of tube 23 connects to a stem 125 through which a passage extends into the nozzle represented at 126. Nozzle 126 is similar to the nozzle 86 described in connection with FIGS. 18 and 19 except that nozzle 126 is extended in its axial direction for the purpose of passing through the bore 127 in the partition section and projecting moveably through the bore 128 in the manifold section. The nozzle 126 carries a disc corresponding to the disc 85 in FIG. 18 and all of the other components in the assembly shown in FIG. 21 are similar to the components shown in FIGS. 18 and 19. A shoulder 129 formed on nozzle 126 limits the entry of nozzle 126 through bore 128 into the manifold section 117 but enables the nozzle to be depressed in the direction of valve 30 as hydraulic pressure is supplied to gasket 84 as explained in connection with the structure of FIGS. 18 and 19 for delivering a spray of starting fluid to the manifold.

The monitoring arrangements of my invention may be utilized for warning the engine operator of the condition of the atomized spray in the manifold so that the operator may replace the pressurized can of starting fluid. The standard can of starting fluid may last over an extended period of time depending upon the frequency of use. The can as it becomes exhausted is readily replaced to insure maximum convenience and safety in engine starting. Control of the valve for spraying the fluid contents into the manifold section is eflected from the dashboard of a vehicle where the applicator is applied to a vehicle engine or from the control panel of the engine Where the applicator is applied to stationary engines.
