Description
10~99S
The pr~sent invention relates to apparatus for controlling the o~eration of a snow plow and in particular to a manually operable stick shift therefor.
Vehicular type snow plows as for example employed to clean roads, airports or the like have very large plow blades movably supported by hydraulic cylinders.
During use, the blade must at times be raised, lowered and adjusted i.e, angled to the right or left for most effec-~ive operation. Since the operator is also charged with safely operating the vehicLe, suitable means for control-ling the movement of the blade must be provided. To this end, four position gate type shift mechanism are known having a stick shift movable from a neutral position (N) into one of four positions thereby causing contact with electrical switch means controlling the drive means for/or the hydraulic cylinders activating the plow. In this manner, the plow may be raised (R), lowered (L), a~justed right (AR) or adjusted left (AL) as may be desired. How-ever, these kno~n constructions have the serious disadvan-tage that additional operations such as providing "plow under dead weight" (P) can only be effected by the use of a gate type gear shift mechanism having more than four shift paths for the use of auxiliary controls separate from the shift mechanism. A gate type gear shift of more than four paths is extremely expensive and further more rules out the ability to simultaneously control the basic movement of the plow and the additional operation thereon.
Auxiliary controls, independent of the gate type shift 107~95 mechanism make it more difficult to operate the snow plow and particularly require that the operator's eye be removed from the road.
In addition to the above mentioned additional operation of "plowing under dead weight" which is synony-mous to the float position of the vertical cylinders supporting the plow, the operation "unlock in adjust direc-tion" is of special importance This additional operation is synonymous with a float position of the hydraulic cylinders for the lateral adjustment of the blade. Prac-tical handling of the snow plow requires that these two additional operations "plowing under dead weight" and "unlocking in adjust direction" be controllable simultan-eously together with certain operations calling for the movement of the plow The present invention provides a shift arrange-ment utilizing the gate type shift app~ratus menticned above so that additional operations can be performed which over-lap certain of the basic movement operations and which can be controllable by the operator without the requirement for visually locating the controls. Thus, any operator mistakes which may very easily lead to damage of the snow plow can be obviated.
According to the present invention, control elements for two additional operations, such as "plow under dead weight" (P) and "unlock in adjust direction" (U) combined with the hand .. -.. : ..... . .
.' ' ' grip of a stick shi~t~ This enables two additional operations P and ~ to be accomplished by the driver in a blind manner and ~ith the hand embracing only the stick shift. It enables the driver, in order to avoid constraints of the blade suspension, to control the operational move-ments by adjust left and adjust right simultaneously with the operation "plow under dead weight" and the operation "unlock in adjust direction" simultaneously with the opera-tion of raising and lowering the blade.
According to the present invention, the shift apparatus is designed so that the operation associated with each shift path remains engaged only so long as the stick shift is held in that position. Preferably one of the additional control elements is a hand grip mounted to be shiftable along the axis of the stick shift while the other one of the control elements is a push button capable of being actuated by the thumb of the operator while the operator is manually holding the stick shift. Both these control means are resiliently biased so that they are in actuating position only so long as the operator exerts an actuating force thereon. Both these control me~ers are designed to operate a pulse switch providing the necessary signal for control of the drive means effecting the particular plow operation.
Further, in accordance with the present inven~
tion the stick shift mechanism has a novel design so that it is also resiliently biased mainly in engaged position only so long as the operator maintains the stick shift in .
-. .-~()7499S
that position and is automatically returned to the neutral position once the operator releases control thereof.
The full details of the present invention are set forth in tne following description and are shown in the accompanying drawings.
In the accompanying drawings:
Figure 1 is a perspective view of a shift appara-tus embodying the present invention and;
Figure 2 is a sectional view through the arrange-ment of Figure 1.
As seen in Figure 1, ~he shift arrangement briefly comprises a control or stick shift, generally depicted by the numeral 1, comprising an elongated rod 4 set in a slide block 5 mounted on the upper surface of a generally rectan-gular housing 6. The interior of the housing 6 contains four sets of electric contacts the terminals 7 of which extend through the outer side faces for connection by electric lines to the conventional control members of those drive means necessary for actuation of the individual operations, tfor example, electric or hydraulic motors or cylinders). The stick 4 is~pivotable in four shift paths Wl - W4 so that its inner end makes selective engagement with the necessary electric contacts to effect the opera-tions left, right, raise, lower, as indicated in Figure 1.
At its upper end of the rod 4, the stick shift 1 is provided with a slideable hand grip 2, in the top end face of which is mounted a push button 3, The hand grip 2 is mounted so as to slide axially of the rod along path '.
107~995 II and its do~nward movement is designed to effect on addition operation as for example "plow under dead weight"
(P) The push button 3 is mounted so as to be depressable into the end of the rod 4 along path III and on its down-ward movement is designed to effect a second additional operation such as "unlock in adjust direction" (U).
The detail construction of the shift arrangement is shown clearly in the sectional view of Figure 2. The housing 6 is formed with a plurality of side walls having a cover 8 in which is formed a central bore, through which the-rod 4 extends. The bore has a conically outward tapered upper section and a central cylindrical lower section. A rubber, plastic or other elastic material ball joint ring 9 fits over the rod 4 and journals the rod within the lower seciton of the bore for substantially universal movement therein. The bottom of the housing is c'osed by a wall 15, havir.g a cnetral ~utwardly domad section 14 surrounded by a peripheral flange which is secured to the side walls of the housing. Suitable gasket seal and insulating members are inserted between the bottom wall 15 and the side walls as well as between the top covers and side walls.
The lower end of the rod 4, is provided with a hollow section in which is slideably inserted a tubular sleeve 12 mounting a ball 13 at its outer end. The sleeve 12 and ball 13 are biased out~ardly by a compression spring 12a the inner end of which abuts against a stop or wall within rod 4, so that the ball 13 is caused to 10749~S
normally side on the inner surface of the dome portion 14 of the bottom wall.
Fixedly mounted on the rod 4 within the housing 6 is a doughnut or annular shaped contact ring 10. Secured through the side walls slightly above the contact ring 10 are the contact buttons of normally open spring biased push button switches ll to which the terminal 7 are connected.
Upon deflection of the rod 4, about the pivot point formed by the journal 9 shown in dotted lines, the annular ring 10 is caused to push, and thereby actuate a selected contact 11. Automatic return of the stick 4, to its neutral position is assured by the interaction of the ball 13 on the domed surface 14. Thus, the activation of any one of the contacts lasts only so long as the operator holds the stick in the selected position.
The upper end of the rod 4 is provided with an arlnular collaL 16 and a hollow axial section in which a first plunger 17 fits. The first plunger 17 is itself provided with an annular collar 18 and is also hollow receiving a second plunger 19 to which the push button 3 is secured. The hand grip has a central bore o~ varying diametric sections. The lower section contains a com-pression spring 20 abutting against the collar 16 and an inner shoulder acting to normally bias the hand grip axially upward of the stick 4. The upper section of the hand grip bore contains s similar spring 21 abutting against the collar 18 and the push button to normally bias the push button upwardly.

lQ74995 Cooperative contact ~embers 22 and 23 are formed on the lower collar 16 and the lower end of the hand grip respectively which engage on the depression of the hand grip Cooperative contacts 24 and 25 are formed on the upper portion of the hand grip and the push button 3 which engage on the depression of the push button~ Preferably, the contacts 23 and 25 are spring load balls permitting the grip and push button relatively free movement while insuring positive detent contact. Suitable electrical line connections from the contacts extend through the grip, push button, plunger and rod into the housing 6, and there to one of the exterior terminals 7 to means for providing an electrical pulse signal to the associated drive means. Bec~use of the spring loading of the hand grip 2 and the push button 3, those contacts controlled by them can only remain engaged so long as the operator dispenses the respective grip or button and once these are let go, the contacts return immediately and automatically to the neutral or open position.
It will be seen from the foregoingthat application of the hand grip and push button are independent of each other as well as independent of the gate type gear shift actuated by pivotal movement of the rod 4. All actions require a positive movement on the part of the operator and end in an automatic return to neutral position once this positive action ends. While the operation of the hand grip control element may be independent of the operation of the switches in the housing, suitable inter-~0`~4~ 9 5 locks, either mechanical or electrical can be suppliedso that certain operations can be accomplished simultaneous-ly or mutually eY~cluded. Namely it may be desired to provide an interlock by which the "adjust right and left"
(AR) (AL) is obtained automatically with the "plow under dead weight" (P) and where the "unlock in adjust direction"
(U) is also effected simultaneously with the raise (R) and lower (L) but where the "plow" ~P) is annulled on raising or lowering the blade.
Various embodiments, modifications and changes have been suggested herein and others will be obvious to those skilled in this ~.rt. It is therefore intended that the present disclosure be taken only as illustrative and not limiting of the present invention.
