Application filed .Tune- 13,

To all whom it may concern:

Be it known that I, WILTON S. SCHUYLER, a citizen of the United States of America, and a resident o'fCincinnati in the county of Hamilton and State of Ohio, have invented a new and useful Improvement in an Accelerator for Combustion Engines, of which the following is aspecification.

An object'of my invention is to provide a simple and eflicient accelerator that may be applied to motor vehicles.

Another object of my invention is to provide a device wherein the action of the ordinary hand throttle is in no wise affected by the attachment of a device embodying my invention to-the carbureter.

Another object of my invention is topro-- vide a device that maybe readily mounted upon motor vehicles and that will provide a firm and substantial support to the operators foot.

These and other objects are attained by the means described herein, and disclosed in the accompanying drawings, in which:

Fig. 1 is a fragmental perspective view of a motor vehicle having mounted on it a device embodying my invention.

Fig. 2 is a side elevation of a foot lever forming a detail of my invention.

Fig. 3 is an end view of the device shown in Fig. 2.

v v Fig. 4 is a plan view of a plate and actuating means associated therewith, all of which form details of my invention.

Fig. 5 is a side elevation of the device shown in Fig. 4;.

Fig. 6 is an elevation of a carbureter control arm having mounted on it a device'em- I have disclosed my invention as applied to a Ford automobile. The free end 8 of the carbureter arm 7 is in the ordinary Ford structure connected with a hand throttle by means of a suitable connection. It is customary to provide the end 8 of the carbureter. arm with a bore in which such throttle end engages. In applying my device the throttle connection is disconnected from the arm 7 and the plate 9 is secured upon the arm 7 by passing a suitable bolt '11 through a bore provided therefor in the plate 9 and lodging in the bore in the end 8 of the arm 7. The" plate 9 has formed on it depending lugs 12 and 13 that straddle the frame 31. crank '32 that is pivotally connected'to the or CINCINNATI, oHIo.

direction in which the arm 7 is capable of it abar 14 that is pivoted'at 15 upon the plate 9 and is provided at its free end with an aperture 16 for the reception of the throttle rod connector that was removed from the bore in the end 8 of the carbureter arm reciprocating pin 17 has its one end 18 -pivotally mounted'npon a stud 19 carried by the bar 14:. The plate has anupwardly extending flange 20 provided with an aperture through which the pin 17 may be reciprocated. A washer 21 is mounted on the pin 17 adjacent its pivotally mounted end, and a spring 22 mounted on the pin 17 has its opposite ends in abutment upon the washer 21 and the flange 20. Alug 23 struck upwardly from the plate 9 limits the movement of the bar let under the influence of, the spring 22'. The plate is provided with an aperture 24: for the reception of one end of a connecting rod 25 extending forwardly from the foot pedal 26. The rear end of the connecting rod 25 has .a sliding pivotal mounting upon a pin 27 pivotally mounted at the lower end 28 of an arm 29 fixedly carried at one endof a crank shaft 30 extending transversely of the foot lever The crank shaft 30 carries a lower end of a reciprocating plunger 33 carried by a lateral extension 34 formed on the frame 31. A suitable head 35 formed on the upper end of the plunger 33 is adapted to be engaged by an operators foot and 1 to be moved downwardly through an open ing in the lateral. extension 34L through whichthe plunger reciprocally extends, and against the yielding resistance of the spring 36 having its opposite ends in abutment on the lateral extension and the head 35. laterally extending foot rest 37 extends upwardly and sidewardly on the frame and is adapted to be contacted by an operators foot whereby to give a substantial and rigid support to the operators foot adjacent the head of the plunger.- The frame 31. has formed on it rearwardly extendinglugs 38 and 39. The lug 38 is adapted to be mounted directly upon the housing 40 of the vehicle transmission and lug 39 has pivotally mounted on it a link, 41, the, link being adapted to have its one end secured upon the transmission housing 40. When the device is oun ed one vehicle the 1 0 b rds at the vehicle are disposed substantially at the upper end of the lateral extension 34 thereby protecting the transversely extending crank shaft 30 and the parts associated therewith from maltreatment.

In the operation of my device the downward pressure of an operators foot on the plunger serves to rotatably actuate the crank shaft 30 which motion is utilized for pulling the connecting rod 25 rearwardly. The forward end of the connecting rod, being connected with the plate 9 serves to move the plate in a counterclockwise direction, see Figs. 1 and 4;. During the movement of the plate under the influence of the foot pedal, the bar 14- connected with the handle throttle remains stationary because of its connection with the hand throttle. The spring 22 yieldingly resists movement of the plate 9. The spring 36 yieldingly resists 'movement of the foot pedal. When the hand throttle is actuated the engagement of the bar 14 upon the lug 23 serves to transmit motion from the bar to the plate. At such times the connecting rod 25 is free to slide through the pin 27 thereby avoiding binding of any of the foot pedal parts and the connecting rod 25. It should be noted that operation of the carbureter by either the foot accelerator or the hand throttle will not actuate the other carbureter control means. vThe foot pedal structure, comprising the frame 31 gives a solid and substantial support for the operators foot and pre eludes pulsating of the carbureter valve because of any vibration of the vehicle body.
