AUTOMOBILE CONTROL MECHANISM.

Application filed August 16, 1919.

To all whom it may concern:

Be it known that I, DEVANEY CLAUDE ED- WAT-1o Tnanvon, a subject of the King of Great- Britain, and resident of 119 Huron street, in the city of Toronto, county of York. Province of Ontario, Dominion of Qanada, have invented certain new and useful improvements in Automobile Control Mechanism, of which the following is a specification.

The invention relates to improvements in automobile control mechanism as described in the present specification and shown in the accompanying drawings that form a part of the same.

The invention consists essentially of the novel construction of the hand lever adapted to operate the controller shaft and in the novel means for locking said lever.

The objects of the invention are to provide a form of control lever particularly adapter. for Ford cars, which may be located centrally of the car, thus permitting of easy access to the car by either side door, to provide an ancient means of locking said hand lever. and generally to provide a form of automobile control mechanism which will be inexpensive of construction, simple of operation. durable and efficient.

in the drawings, Figure l is a perspective of a portion of a car with the flooring broken away to disclose the parts located therebelow.

2 is a vertical sectional view through the hall located at the top of the hand lever, said view being taken substantially on the line .-l--i of Fig. 3.

Z3 is a plan view of the lever top with a portion of said top broken away.

Fig. is a cross section through the controller shaft taken on the line 13-13 of Fig. 5 with one half of the adjustable collar shown in dotted lines extended.

Fig. 5 is a detail of one end of the hand lever showing the manner in which same is secured to the controller shaft.

Like numerals of reference indicate corresponding parts in the various figures.

Referring to the drawings, 1 represents the frame of the car on which is supported the flooring 2 through which project the foot levers 3 as customary.

% is the controller shaft transversely ar- Specification of Letters Patent.

ranged and mounted in bearings in brackets secured on the under side of the frame 1.

6 are links, rigidly secured over the outer ends of the controller shaft 4, and projecting at right angles thereto and having pivotally secured to the ends thereof the brake rods 7.

8 is a hand lever projecting through a slot 9 located substantially centrally of the car floor, said lever being provided at its lower end just beneath said floor with a pair of outwardly and downwardly radiating arms 10 adapted to encircle the top side of the crank case 11 and to be secured to the controller shaft for the purpose of operating same.

The ends of the arms 10 may be rigidly secured to the controller shaft in any desired manner but in the drawings said arms are shown as each having an enlarged portion 12 shaped to form the top half of a collar and having a portion 13 hinged thereto as at 1 1 and forming the lower half of said collar, said collars being adapted to be secured around said controller shaft by means of bolts 15 securing together the flanges 16 of each of said collars.

The inner walls of the collars are provided with notches 17 forming teeth 18 adapted to engage the controller shaft and thus eiiectually prevent said collars from slipping.

19 is a sector located within the slot 9 in the flooring and extending through a slot :20 in the enlarged lower end of the hand lever 8 and being provided with right angle ends 21 aoapted to be secured to the under side of said flooring. said sector being provided on its lower edge with teeth 22.

23 is a pawl arm slidably mounted in a longitudinal slot 2% in the hand lever 8 and being provided at its lower end with a sliding pawl mechanism 25 located within the enlarged lower end of said lever and normally engaging the teeth 22 of the sector 19.

The pawl arm projects upwardly into the enlarged and preferably ball shaped top end 26 of the lever arm 8 and is provided with an enlarged top portion or plunger 27 adapted to slide within an opening 28 in said ball, said opening being somewhat longer than said plunger and being adapted to accommodate a spring 29 located between the lower end of said opening and the lower endof said phulger for the purpose of holding said pawl arm normally to its uppermost position and thus hold the pawl firmly in engagement with the teeth 22 of the sector 19.

It will be apparent from the foregoing that so long as the pawl engages the teeth of the sector the hand lever will be held firmly to its position and thus prevents rotation of the controller shaft and to permit of operating said hand lever it is simply necessary to push downwardly on the top end of the pawl arm and thus release the pawl from the sector. Upon release of pressure on the pawl arm the spring 29 will of course force the pawl arm upwardly and,

cause the pawl to again engage the sector 19.

30 is a plate sliding in a horizontalslot substantially centrally of the ball 26, said plate being slightly greater in length than the thickness of said ball so as to provide a projecting portion or handle 32 and being provided with a slot 33 therethrough through which the plunger end 27 of the pawl arm-operates, said slot being slightly longer than the thickness of said pawl arm and being cut away at one end to form a square portion 3% adapted to be inserted in a slot 35 in the plunger 27 when it is desired to lock the pawl arm to its uppermost position.

36 is an opening through one end of the plate 30 for the insertion of a padlock 37 for the purpose of locking said plate within the slot in the plunger 27.

38 is a spring operating in a horizontal groove 39 in the roof of the transverse slot disengages the pawl from the sector 19 and permits of said hand lever being reciprocated to rotate the controller shaft. When it is desired to lock the hand lever to any desired position it is only necessary to allow the pawl arm to be forced upwardly to its uppermost limit by means of the spring 29 and then to insert the plate 30 in the slot 35' in the plunger 27 by simply pressing inwardly on the projecting portion 32 of said plate which forces the opposite end of said plate out from the opposite side of the ball 26 and permits of a padlock being secured in the opening 36 and thus effectually preventing said plate from being disengaged from the slot in the plunger. Upon the removal of the lock 3'? the spring 38 immediately forces the plate 30 from the slot in the plunger 27 and permits of free usage of said hand lever.

7 By the use of this invention free access may be had to the interior of the car by either side door as the hand lever is located centrally of the car in place, of at one side as in Ford car construction. It will also be seen that the various parts are so inclosed that when the device is locked it is absolutely impossible to operate the hand lever except by removing the padlock, thus effectually preventing theft of the car.

What I claim is:

In automobile control mechanism, the combination with a controller shaft shaped to extend around the lower side of a crank case, of a pair of arms having enlarged lower ends and hinged portions forming clamps adapted to grip said controller shaft on opposite sides of said crank case, said arms being shaped to extend around the top side of said crank case av hand lever rigidly connected to the upper ends of said arms, and a sector. 7 V
