ACCELERATOR FOR AUTOMOBILES.

' Applicationfiled June 26,

To all whom it may concern:

Be it known that I, CHARLES L. MIToHELL, a citizen vof the United States, residing at Randolph, in the county of Cedar, State of Nebraska, have invented certain new and useful Improvements in Accelerators for Automobiles; and I vdo hereby declare the following to be 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.

This invention relates to accelerators for automobiles. V I g j V The object of the invention is to provide a practical attachment for automobiles which are not initially provided with accelerators. Thus, the embodiment which is hereinafter described is particularly adapted for attachment to a Ford car, so that it may be equipped with a foot pedal accelerator in addition to the usual hand throttle lever.

WVith the above object in View, and such others relating to the details of construc tion, as may hereinafter appear, my invention will now be fully set forth and described, reference being had to the accompanying drawings.

In the drawings Figure 1 is a perspective view of the attachment, the necessary parts of the engine to show the application of the invention being dotted in,

Fig. 2 is a plan view of the elements,

Fig. 3 is an elevation of another of the elements, and

Fig, 4 is a partial plan view of the attachment.

Referring more particularly to the drawings, 1 represents the engine, having the usual carbureter of a power plant; and the carbureter having the usual throttle arm. The steering post 4 carries the throttle rod in the usual manner, terminating at its lower end in the right angularly projected arm 5.

To the above parts are connected the various elements of my invention. A standard or rod 6 is mounted on the bottom structure of the automobile frame, and lies alongside the engine, so that its upper end may be secured to the latter by means of a clip 7 which is preferably connected to one of the bolts of the water inlet connection. Upon the standard thus erected is mounted first an elongated sleeve 8 whose upper end provides a seat for a collar 9. The collar is Specification of Letters Patent. Patented July 20, 1920.

1917. Serial No. 177,029.

formed of a coil of stiff wire, and at the upper end of thecoil the wire is extended tangentially of the coil to provide an arm 10, while at the lower end of the coil the wire is similarly projected to form an arm 11, which is disposed in substantially right angular relation to the arm 10. The arm 10 terminates in an eyelet in which is hooked oneend of a rod 12 which replaces the usual connection between the throttle rod connecting arm 5, so that as the collar .9 is rotated, the throttle will be accordingly moved. The arm 11 also terminates in an eye and re ceives therein the hooked'end of a rod 13, which is provided at its upper end with a foot pedal 14:, said rod 13 extending through a suitable aperture in the foot board of the car arranged alongside of the brake and clutch pedals. Also, the arm 11 is connected to a spring 15 which extends to' a fixed portion of the engine or car body to normally retract the arm 11, so that the foot pedal 14 will stand in elevated position.

Also mounted upon the standard 6, so as to rest upon the collar coil 9, is a second collar 16, which is similarly formed of a coil of stiff wire, and the wire at the lower end of I the coil is extended tangentially of the coil to provide a laterally and downwardly extending finger 17 which normally lies against the arm 10. The wire at the upper end of the collar 16 is extended at an acute angle in the general direction of the steering post to form an arm 18, which by means of a link 19 is operatively connected to the throttle rod connecting arm 5. Thus, when the hand throttle lever is operated, the collar 16 is rotated through the link 19, and the finger 17 bearing against the arm 10 causes the actuation of the throttle. However, when the foot pedal is depressed, the collar 16 is not molested, since the arm 10 is free to leave the finger 17 upon its forward movement.

The operation of the foregoing mechanism is apparent from its description, it being only necessary to note particularly the simplicity and effectiveness of the device and the fact that it is capable of being attached to any car of the Ford type which is already in use, when it is desired to equip the same with a foot accelerator.

What I claim as my invention is 1. An accelerator for automobiles comprising a standard adapted for securement adjacent the throttle rod connecting arm of an engine structure, a length of Wire coiled on the standard to form a sleeve and having connection for said second arm of the Wire,

a second length of Wire coiled on the standard to form a collar, one end of said coil being extended to form an arm adapted for connection With the throttle rod connecting arm and the other end of the'coil'being extended and laterally turned to engage the first specified arm of the first named collar coil.

2. An attachment for automobile engines comprising a standard for engagement With the engine base and adapted for connection at its upper end With a portion of the engine, a sleeve disposed upon the lower portion of the standard, a Wire helix rotatably encircling the standard and resting upon the sleeve and having its end portions con-v helix rotatably disposed upon the standard and resting upon the first helix, the lower end of the Wire or the second helix extending radiatingly from the helix against an arm of the first helix andzbetween it and the other arm of the first helix; theupper end portion of the Wire of the second helix extending also radiatingly "from the helix and having a terminal hook for connection With the hand throttle rod of the engine.
