' 2 Claim.
This invention relates to valves for gas stoves and equivalent cooking and heating appliances and more particularly relates to single outlet valves having a plurality of flow positions of the general type disclosed in Patent No. 2,224,566;
dated December assignee.-
The principal obJect oi the invention is to provide a conveniently operable valve of this type in which the valve becomes locked when moved to one position and apprises the operator, by means of an audible signal, when the valve plug has completed its movement from one position to another.
Another object 01. the invention is to provide a valve having a plurality of fixed flow positions with a single throttling means for adjusting theflow in the several reduced flow .positions, and having means for audibly indicating to the operator by a clicking sound when movement of the valve from one position to certain other positions has been eifected and also having other means for locking the valve in one position and for indicating by a clicking sound when said locked position has been reached.

Figure 19 is a section taken on line I 8-19 of Figure 18.
Referring more particularly to the drawings, the valve body or casing I has the inlet extension 2, adapted for connection with a manifold or other suitable source of gas supply not shown. In the particular embodiment of the invention disclosed the extension 2 threads into the gas manifold from the top. A rotatable valve plug 3 for controlling the flow of gas through the casing seats within the tapered bore 4. The valve 3 is formed with three inlet passages, a large or full flow passage 5, and smaller reduced flow passages 6 and 1 respectively adapted to be moved into and out of communication with supply passage 8 in extension 2, thus providing three open or on positions and a closed or off position. An axial passage or bore 9 in the plug places the transverse passages 5, 6 and l in communication with the axial outlet passage Ill in the casing. The reduced flow passages 6 and I lead from depressions or recesses II and I2 preferably equal in size to and in a common plane with the full flow passage 5.
The valve plug 3 is formed with an inner hollow stem portion iii, the bore It ofwhich is threaded to receive a throttle screw l5 for a purpose hereinafter described. Oppositely disposed longitudinally extending ribs it formed on the inner stem portion 13 are adapted to be slidably but non-rotatably received within oppositely disposed slots fl'i formed in the inner end of a hollow outer stem portion it. As the ribs I6 are of rectangular shape in cross section and the slots ll correspond in size .and shape with the ribs, the outer stem member while free to slide'relative to the inner stem portion locks the latter and the valve plug 3 against independent rotation with respect to the outer stem portion. A coil spring l9 seats at one end against a shoulder 20 on the valve plug and at its other end seats against or resiliently engages the inner face of a latch and click washer 2|. This washer 2i, which is provided with an opening 22 for slidable but non rotatable connection with the outer stem portion |8,is resiliently forced by the spring 19 against an interrupted annular rib 23, on the outer stem member or portion iii. The spring l9 thus resiliently opposes limited inward movement of the outer stem member relatively to the inner stem member, when the valve parts are assembled. Independentrelative rotary movement "or the lock and click washer with respect to the outer stem member isprevented by the engage--- ment of a flat wall 24 of the washer opening with a flat face 25 formed on the outer stem portion A cap 28, having a central opening 21 through which the outer stem portion I8 of the valve extends serves to confine the valve plug 3 within the valve casing. The cap also loosely receives and houses a latching and clicking ring 28, a clicking washer 28 and an irregularly bent springe tension washer 38, sleeved over the outer end of the outer stem member or portion I8, in the order named. The latching and clicking ring seats upon the outer face of interrupted annular rib 23 previously mentioned as being formed on the inner end of the outer stem portion and the click washer 28 seats on the outer face of latching and clickingring 28 and is resiliently held in place, in an obvious manner, when the cap 28 is screwed home on the casing and into clamping engagement with the spring washer 38. A handle provides convenient means for turning the valve to its oil and various flow positions. These several positions of the valve are indicated visually by the marker 55 two shoulders 34 and 35 formed in opposite edges of the arcuate flange 3|, which are engaged by a radially extending stop lug or finger 38 on the periphery of washer 2|, for positively limiting rotation of the valve plug. This member 28 is also formed with an inclined flange 31 terminating adjacent the stop shoulder 34 to form a stop and latch shoulder 38 which latches the valve plug against rotation in one direction when the'finger 36 rides off the inclined flange and snaps into the gap or space 52 between the shoulders 34 and 38.
The clicking washer 29 is formed with a straight wall or flat portion 48 for engagement with the fiat face 25 formed on the outer stem portion I8 thus locking this washer against relative rotation with respect to the stem and valve plug but leaving the same free for slight axial movement. The washer 28 is also formed with radially and oppositely disposed ofis'et portions or ribs 4| adapted for resilient clicking engagement with corresponding radially extending depressions or slots 42 formed in the latching and locking ring 28. Under the action of spring tension washer 38 a readily audible sound is made by the clicking washer as the ribs 4| are brought into register with and are forced into the depressions 42, thus indicating to the operator that movement of the valve from one flow position to another has been efiected.
The outlet end of the casing I has an orificed hood 43 in screw threaded engagement with the reduced threaded outlet end portion thereof, the hood having a discharge outlet or orifice 44 with 'which a needle point or valve 45, fixed to or integrally formed with outlet end of the casing I, cooperates. A tubular insert sleeve or member 46 having a press fit in a socket or seat 41 in the irmer end of axial'plug passage 8, is formed with spaced elongated longitudinally disposed rectangular slots 48 and 49 respectively, opening through the inner peripheral edge of the insert for a purpose presently understood. The low and medium flow restricted inclined inlet pas-' sages 8 and 1 respectively, preferably correspond in size with and are spaced apart similarly to and communicate at their inner ends with these slots 48 and 48, which in turn place the inclined passages in communication with thepassage 9, the flow being upwardly and inwardly to and through the slots 48 and 43 and thence outwardly through the cylindrical bore 46' of the member 48 to passage 9 and finally out through outlet orifice 44. The relative width of slots 48 and 48, as made when valve is manufactured, determines the ratio of the low and medium flow to each other. The extent of this flow is controlled by means of the partially threaded. elongated throttle valve I5 mounted in the axial partially threaded bore I4 formed in the inner valve stem I3 and communicating with the interior of the open ended insert or sleeve 48. The inner unthreaded portion of the bore I4 is oi the same size and axially aligned with the bore of the insert, the latter being adapted to snugly receive the reduced smooth cylindrical inner blunt end of the throttle valve I5 when the latter is screwed home in an obvious manner. Inward movement or the valve I5, causes the valve to overlie and of course cut down the effective area of the narrow slots 48 and 49 in the insert member 46, and movement in an opposite direction progressively uncovers the slots with reverse efiect. It will also be seen that when adjustment is made the flow in either flow position of the plug valve is accurately proportional to the flow which occurred in either position before such adjustment was made. Adjustment of the throttle valve is made by engaging the slot in the threaded end thereof with a suitable tool.
When the valve structure is installed on a gas range or the like the hood 43 will be set with respect to the outlet needle valve or point 45 so as to establish an orifice 44 corresponding to the High" position of the valve plug, at which time maximum flow is obtained through supply passage 8, large inlet opening 5 direct to plug bore 9- and thence out through orifice 44 to the burner, not shown, Thereafter there will be no adjustment of the hood which thus remains in fixed position. The inclined low and medium lnlet passages 6 and l, which leadfrom gas receiving recesses II and I2 in the valve plug, are much smaller than the inlet opening 5, low and medium inlet passage 1 has approximately twice the capacity of low passage 6 so that these respective passages when brought into register with supply passage 8 will accommodate sufficient gas to support a Low and Medium burner flame respectively, on all kinds of gases. The operator also generally finds it necessary, when installing the range,'to adjust the throttle valve I5 so as to procure the desired accurate reduced flows, according to the kind and quality of gas being used in the particular locality in which the installation is made, and of course depending upon the nature of the burner being serviced.
It may be noted here that with the handle 5| occupying the position marked Ofi'" there will be hollow of gas through the valve; but when the handle is turned in a clockwise direction from Oil to High and thence to Medium and finally to Low in steps of approximately ninety degrees; or in a reverse direction from Low" to Medium and High" in the order named, the supply passage 8 will register with the respective resilient movement of the split stem when the inlet orifices in the plug valve and the appropriate volume of gas will flow through the valve.
For convenience in assembling the valve parts;
the valve stem and the valve plug are rotated so as to bring the finger 35 on lock and click washer 2| into the latched or off position with the shoulders 34 and 38 preventing rotation of the plug valve in anticlockwise and clockwise directions respectively, before screwing cap 26 upon the casing. extension 33. To unlatch or unlock the valve from its Ofl position it is necessary to force the outer stem member 18 and the washer 2| inwardly against the tension of coil spring l9 until the finger 36 of washer 2! is clear of the lock shoulder 38, Clockwise movement of the stem then causes the valve plug to move first to "High and then to Medium and finally to Low flow positions. As these respective positions are reached the housewife is informed by reason of the fact that the ribs 4| snap into the depressions 42 in latching ring 28, with an audible click, under the action of spring tension washer 30. In turning the valve in a reverse or anticlockwise direction from Low" through Medium and High" to "Off" flow positions the same clicking sound is repeated but when Off position is reached the washer finger 35 not only snaps into the gap or space 52 between shoulders 34 and 38, but the finger becomes locked against rotation in either direction.
From the foregoing it will be seen that movement of the valve to certain flow positions is indicated to the operator by an audible click and that when the valve reaches Off position the operator in addition to being apprised of this fact by means of the audible clicking of the latch and clicking washer 2|, is prevented from accidently turning the valve to any other position.
The handle 5| is formed with a substantially D-shaped centrally disposed recess for receiving the correspondingly shaped outer end of the outer stem portion I8. To insure a tight resilient clamping fit between the stem and handle, the former is split as at 54 to permit of some little handle is forced thereon,
What I claim is:
