DRIVING ATTACHMENT FOR AUTOMOBILES.

Application filed May '3, 1924. Serial No. 710,945.

' To all whom it may concern:

Be it known that I, VILLIAM H. LoNsnALn, a citizen of the United States of America, residing at Brownsburg, Province of Quebec, Canada, have invented certain new and useful Improvements in Driving Attachments for Automobiles; and I do'hereby declare that the following is a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The present invention pertains to an attachment for automobiles, the movement of which is controlled by a clutch pedal and reverse pedal. The attachment is particularly adapted to Fordcars.

'- culty in driving a The object of the invention is the provision of means which may be applied to the control apparatus of a car of this character in "order to make the control movements thereof similar to the movements pertaining to automobiles of the more general type, wherein the high, low and reverse speeds are attained by an operating lever and the clutch. is actuated from a pedal. Itis well known that a person who has driven the more. common type of car for a length of time becomes so accustomed to the movements-thereof that he has reat difficar of the Ford type. The habit is most dangerous and asserts itself more readily when the driver in the Ford car findsbhimself in a tight position and must act quickly. Instead of executing the movements necessary for the control of a Ford car, he is inclined to operate as if driving a car of the other type, and thus exposes himself to the possibility of accident. This difliculty is overcome by means of the present i tion, since a device con v structed in accordance therewith and applied to a car of the Ford type renders the control movements of the car similar to those of a car of the more prominent type.

The invention is fully disclosed in the .following description and in the accompanyingdrawings in which:

. Figure 1 is a side elevation of the device applied to the transmission casing of a Ford automobile, the'dev'ice being in'neutral pol sition Figure 2 is a plan view corresponding to Figure 1; I

Figure 3 is' an elevation corresponding toFigur-e 1, showing the of parts when-in everse P S tiQ i 1 Figure 4- is a-similar elevation, in low speed position F'gure 5 is -a section on the Figure 1; T Y j Figure6 is a similar section showing the latch released from the'slidingba-rs;

, Figure 7 is a section onthe line 77 of Figure 2; Y

Figure 8 is a similar section showing the position ofparts in high speed position;

Figure 9 is a section on the line 9 -9 of Figure 1'; Y Y

Figure 10 is a side elevation showing the parts in highspeed position; I V Y I Figure 11 is a fragmentary plan view corresponding'to Figure 10; and, I Figure 12 is a fragmentary elevation of line 55 of the slow speed shaft and partscarried thereequipped with'a cover 2 which has a substantially vertical extension. 3 projecting rearwardly of the casing. The cover is formed with a large opening (not shown) the latter being closed by means of a sup plementary cover 4.

On the extension or platform 3 is mount- I ed a box 5, the top of which'is covered by a plate 6 having an H-slot'7. In the wallsof the box is supported a sliding bar 8, to which is secured a substantially upright lever 9 projecting through the slot 7. One end of theslidingbar 8 carries'a rod 10, from the lower end ofwhieh projects a finger 11, the purpose of which is pointed out below. A swinging plate 12 is pivoted as at..13 to the platform 3 and is formed with aslot 14 through which the rod 10 passes.

A substantially vertical bracket 15 is fixed to the'forward edge of the platform 3 by means of bolts 16 which pass through the platform and through a perpendicular web 17' extending from the plate. To the rear edge of the platform isfsecured an angle bar'18. A; pair of ' yokes 19 and 20 are supported for sliding movement by the members 15 and 18 and have their ends received in appropriate slots 21 and 21' cut through these members respectively, Theforward an at th E 61 has: e we 19? hi e t e forward end of the yoke has a similar notch 20, each of which is adapted for en gagement in the slot 21.

The reverse pedal which forms part of the Ford driving apparatus is removed, as may be seen from Figure 9; The slow speed shaft 22 is somewhat longer than usual in order to accommodate the block 23 key-ed thereto and lying. adjacent the hub 24' of the clutch pedal 24. The hub 24 is loose on the shaft 22. From the block 23 extends an arm 25 having one end of a link 26 pivoted thereto, the remaining end of the link being pivoted to the forward end of the yoke 19 as may be seen from Figure 4;

A fork 27 is supported by the upper part of the bracket plate 15 and serves to support a rocker armz28 pivoted therein. The lower end of this: arm is pivoted to. the forward end of the yoke 20, as shown in Figure 3. An arm 29 is secured to the reverse pedal shaft 30 and has pivoted thereto one end of a link 31, the remaining end of this link being pivoted to the upper end of the rocker arm 28. p

The cliitch pedal'24: is free on the shaft22 and is extended downwardly beyond this shaft, as indicated by the numeral 32. A rocker arm-33, fixed to the usual clutch lever shaft 34' has. one end thereof joined to the extension 32 by means of an adjustable link 35. .The remaining end of the rocker arm carries a finger 36' from which extends a slotted plate 37.

At the rearend of the finger 36, is provided a stop member 38 adaptedto engage the plate 12, asv shown in Figures 2 and 6 AL U-sha 36d lifter39 pivoted to the lower part of the plate 15 is adaptedfor raising each sliding bar for releasing the notches 19 and'20" from engagement in the slots 21. The free end of the latch has an extension dO'which' is received in the slotted plate 37 Assuming that the lever 9 is in neutral position,,that is between the legs of the H slot, as shown in Figure 2, the clutch pedal 24 is pressed downwardly prior to any ad' justment of the lever. In this connection it is to be not'ed'tliat the clutch pedal must be pressed before making any change in the transmission gearing. In order to throw the gearing into high speed, the lever is pulled to the right and intothe shorter leg of the slot. As the rod 8. shifts, it swings the plate 12.0ut of the path of the-stop 38. Since the clutch levershaft 34 is under torsion, as usual, it isnow free to turn its full extent whereupon the clutch is engaged for direct drive. The rocker arm 33 is brought to the position shown in Figure 10-and raises the clutch pedal 24, so that the direct drive may be broken bypressing downwardly on this pedal,

To 'bringthemachineinto low speed, the clutch pedal'is pressedwhereupon the rocker arm 33 and parts carried thereby are returned to the position shown in Figure 1. The lever 9 is brought into the longer leg of the H-slot, whereupon the rod 10 engages the plate 12 and swings it outwardly into the path of the raised stop 38. A slight downward pressure is applied to the clutch pedal 24: and this'raises the stop 38 from the swinging plate 12, as shown in Figure 6. The up ward movement of the slotted plate 37 raises the pivoted lifter 39 to the position shown in Figure 6 in order to permit sliding of the yokes 19 and 20. The lever 9 is now turned into the lower end of the longer leg of the slot whereupon the finger 11 carried by the rod 10 slides the. yoke 19 forwardly, as shown in Figure 4; During this movement, the yoke 20 is not displaced since it is disposed forwardly of the yoke 19, as shown in Figure 1. At the end of its stroke, the finger l1 rides on the curve 11 formed at the forward end of the body of the yoke 20. Through the medium of the link 26 and arm 25, the slow speed shaft 22 is turned in the same manner as by the usual clutch pedal on the Ford car. Pressure on the clutch pedal is released, whereupon the parts actuated thereby are returned to the position shown in Figure 1. The lifter 39 is likewise returned to the position shown in Figure 5 and allows the notch 19 of the yoke 19 to engage the slot 21 to lock the yoke 19 in place. 7

In order to reverse, the lifter 39 is. operated by a slight downward pressure on the clutch pedal 24: as already described. The lever 9 is pushed into the forwardend of the longer leg. of the H-slot, whereupon the finger 11 carried by the rod 10 draws the yoke 20 rearwardly to the position shown in Fig ure 3; The finger travels in the open part of the yoke 19, and upon reaching the end of its stroke rides on the curve 422 formed at the rear end of this yoke.v It will thus be seen that no movement'is imparted to the yoke 19. At the end of the stroke the notch 20of the yoke 20 is in alineinent with the slot 21 of the plate 15. The pressure on the clutch pedal is now released whereupon the lifter 39 and yoke 20 are lowered, due to the torsion on' the clutch lever shaft 34,

whereby the notch 21 is brought into engagement in the receptive slot 21'of' the plate 15.

lVhen shifting into high, the lifter-39 is again raised and the leverfl9 is carried to the position shown in Figure 11. The swinging plate 12 is engaged by the rod. 10 and carried. out of the pathof the stop 38; The torsion on the shaft 345 now swings the rocker arm 33 to the limit shown in Figure 10, whereupon a direct drive is established as already pointed out.

While a specific embodiment of the. inven tion has been illustrated and described, it is to be understood that various alterations in the details of construction may be made without departing from the spirit of the invention as indicatedby the appended claims.
