provement in an Accelerator Auxiliary Pedal, of which the following is a specification.

This invention relates to a foot rest and operating device foi' pedals, especially for accelerator pedals or .buttons of an automobile. Considerable activity has taken place recently in developing rests for the foot that is used to operate the accelerator and operating devices for the accelerator, so that the position. of the foot may be shifted to rest it. One who is accustomed to driving a car long distances is aware that not only the foot but often the back becomes tired and pained by reason of the strain of pressing the accelerator pedal in the same way for a long period of time. I

lit is the object of the present invention not only toafi'ord a foot rest but also to provide a device which can be used in a variety of .ways to operate the accelerator, and consequently afl'ord relief from too constant straining due to the foot being in the same position for long periods of time.

In the drawings,

Fig. 9 showsone of the links that is used to induce friction between the 'parts. This shows how the link is cupped before it is applied to the accelerator auxiliary so that one can understand how the link when riveted in place is distorted.

Referring to Fig. 7,.the base comprises a triangular plate a; that may be riveted to the horizontal floor board of the car and has a pair of forwardly projecting knuckles t. that are adapted to pivot the forward specification of Letters Patent.

lever cat its lower end. The lower end of this forward lever is of peculiar construction. It has a knuckle portion d at the center through which is a central aperture, allowing the knuckle pin to go through the apertures in the knuckles b, I) of the base plate and this central knuckle. This pivots the front lever to the base. The front lever, however, is provided with an additional rearwardly' projecting knuckle 6 adapted to be straddled by the two knuckles f, f of the rear lever 57. through the central apertures in these knuckles serves to pivot the front and rear levers together.

The base plate is provided with a hump The knuckle pin going or cam h whlchrests under the forward end of the rear lever. This forms a fulcrum for the rear lever to allow the rear -lever both to swing and slide on this fulcrum in obedience to the requirements of the fixed pivot of the front lever.

Underneath the rear lever g is a set screw iwhich can be used to limit the speed attainable by the car, for every time the aimiliary pedal is operated .when the rear lever is in operative position. This rear lever has ultimately got to contact this screw.

By raising it to the desired degree the elected speed of the car may be maintained and not exceeded until the screw is changed or else the lever c is pressed which acts to full speed limit irrespective of the lever g or screw. The screw 71 is also inoperative when the rear lever g is thrown up as shown in Fig. 2. I e

The anti-rattle spring j tends to keep the front lever 0 against the-accelerator pedal when no pressure is upon the front lever. This prevents rattling. To prevent rattling of the two levers and the cam, a pair of links 39 are riveted at each side of the two levers and on the same centers at the pivoting axis. These links are originally cupped, as shown in Fig. 29, and consequently when riveted in place, the links are distorted and tend to bind against the two levers to give a friction that prevents freedom of move ment such as would allow rattling.

The auxiliary pedal is capable of being operated in a number of ways; for instance, the rear lever may be folded back against the front lever, as shown in Fig. 2, and the foot used .simply to press the front lever till llh

lllltl lllh llltl place along the long front lever. This, of course, gives a variety of positions. On the other hand, the rear lever may be opened out, as shown in Fig. 3, and the operator of the car may press the forward part of his foot upon the rear lever and cause the rear lever to fulcrum on the hump or cam h and force the front lever down, as shown by the dotted lines in this figure. gtill a third. and very comfortable position is to place the front of the foot upon the front lever c and the ball of the foot on the rear lever g with the heel overhanging. In this position pressure with the foot exerts its effort on both the levers, tending to open them out in the Way shown by the dotted lines of Fig. 3.

From this description it is evident that a variety of positions is secured, and that the device is simple and cheap to build.

What I claim is:

1. An accelerator auxiliary pedal, comprising a pair of levers having their ends meeting at the ends where they are pivoted and operatively connected at their meeting ends so that pressure on one operates both.

2. An accelerator auxiliary pedal, comprising a pair of levers having their pivoted ends substantially meeting and operatively connected at such meeting ends, and friction devices for preventing too free operation of the levers. I

3. An accelerator auxiliary pedal, comprising a pair of levers having pivotal support near two of their ends which suhstan-- tially meet and operatively connect at these ends, and a pair of distorted links for inducing friction and connecting said levers at their meeting ends.

4. An accelerator auxiliary pedal, having in combination, a pair of levers substantially meeting and pivotally supported at such meeting ends and operatively connected at these ends, and a cam or hump upon which the rear lever fulcrums.

5. An accelerator auxiliary pedal, having in combination, a front and rear lever having substantially meeting ends which are pivotally supported and operatively connected so that movement of one lever operates to move both, and a cam upon which the rear lever fulcrums.

6. An accelerator auxiliary pedal, coinprising a front lever pivotally supported at its lower end, a rear lever pivotally con nected to the front lever below such pivoting of the front lever, and means operating in connection with the rear lever to cause both of the levers to operate when pressure is exerted on one.

"Z. An accelerator auxiliary pedal, comprising a front lever pivotally supported on its rear end, a rear lever pivotally connected to the front lever below the pivotal point of the latter, and a cam or hump operating in connection with the rear lever to cause the two levers to swing when pressure is brought to bear on one.

8. An accelerator auxiliary pedal, having in combination, a pair of levers each pivotally supported near their substantially meeting ends, means upon which one of the levers slidably fulcrums to cause the two to oper ate together, and a set screw adjustable to act as a stop for one of the levers and act as a speed regulating limit.

9. An accelerator auxiliary pedal, com prising two parts, either of which may be pressed to operate the accelerator, and one of which has a limit to control the speed of the car and the other of which has no limit within the possible speed of the car.

10. An accelerator auxiliary pedal, comprising two levers operatively connected but susceptible of certain independent action, and adjustable means to regulate the independent action of one of the lovers for the purpose specified.

In witness whereof I have hereunto set my hand on the l t day of January, 1918.
