In the drawings which show a preferred embodiment of my invention, the numeral 1 designates the cowl of an automobile, 2 the hood, 3 the dash, 4 the toe board,

floor board which taken together serve to locate the position of my invention.

The usual operating r to the toe board by means of screws and lugs 40,

The "only operating part above the housing is the roller 12 mounted to turn-on'a stud 13 which moves-in a slot 1'? provided in the housing. Sleeve 1-8 is threaded and screws onto stud-13 provide. a which the such novel theroller from-sliding down on the'studiand rubbing onthe housing." .The roller is provided witha bushing :10 and is held on the stud 13 by" its head.= :A vflange llis provided on the base of the rollerand is adapted to'be engaged by the sole of the operators shoe and will thereby prevent the upper part of the shoe from touching the roller or from becoming soiled thereby. The lower part of the stud is threaded and is screwed into a threaded holeinthe end of the lever 16 and a nut 15 serves as a lock nut' to prevent it from loosening.

The lever 16 is secured to a sector 19 by means of a screw 20 and a slotted end at 21 which fits partly over a bolt 22. The sector 19 which is shown in Figs. 2 and 3 is provided with teeth shown at 29 which mesh ion 28. This pinion is rigidly secured to the end of a shaft 30. A guide 43 is provided to hold the sector in mesh with the pinion.

A bracket 24 is secured within the housing by means of screws 26 and 27 and serves as a frame to hold the sector 19 and the pinion 28. It is provided with a journal 25 in which the shaft 30 finds its bearing. The sector turns on the bolt 22 which passes down through the bracket and is held by a nut 23. The other end of the shaft 30 finds its bearing in the forwardend of the housing 7.

A depression arm 31 is secured to the shaft 30 by means of a clamp screw 32 and is adapted to engage a plate 34attached to the end of the rod 39 which leads to the throttle valve of the carburetor. The depression arm is provided with a hook 33 formed on its end to engage the plates 34 or 35.

Some cars are provided with a throttle valve lever 38 in place of a button on the end of a throttle valve rod 39 and to adapt my device to this type of foot accelerator I have provided a plate 35 to be attached to the lever by means of a bolt 37 and clips 36 adapted to be bent over the lever.

The operation of the device is as follows:

When it is desired to accelerate the speed of the motor the operator causes the sole of his shoe to engage the flange of the roller 12 causing it to move across the top of the housing above sole of the the roller in section,

frame and depression designates and 5 the shown) through a '7 secured thus .forminga shoulder at 14 which prevents.

the slot 17 and since the roller is secured to the end of the lever 16 and lever 16 is secured to the sector 19 the upper end of lever 16 is moved to the right thereby turning the sector on bolt 22. The teeth of the sector being in mesh with the teeth of the pinion 28 rigidly secured to shaft 30 the shaft is caused to turn and in doing so the depression arm 31 engages the depression plate 34 or 35 as the case may be, depending on the type of car operated, and since the plate is secured to the usual accelerator rod 39 it is pushed forward and downward in the accustomed manner to accelerate the speed of the motor. When the foot of the operator is moved away from the roller the usual spring (not shown) returns the accelerator rod to its normal position which in turn moves the operating parts of my device to their normal position. I

It is to be understood that the form of my invention, herewith shown and described is a preferred example of the same, and that various changes may be made in the shape, size and arrangement of parts without departing from the spirit of my invention or the scope of the accompanying claims.

It will now be seen that I have provided an accelerator for automobiles .and the like which will not be tiresome to the operator because his foot rests firmly upon an immovable housing and that the speed of the motor will remain constant while traveling over rough and bumpy roads because the movement of the foot in operating the device is lateral instead of up and down.

What I claim is:-

1. A foot accelerator including a housing, a slot provided therein, a foot lever fulcrumly mounted in said housing, a stud secured to one end of said foot lever and adapted to travel in said slot, a roller mounted on the upper end of said stud and adapted to turn thereon, a sector provided with teeth and to which said foot lever is secured, a shaft and a pinion rigidly secured thereto and adapted tomesh with the teeth of the sector, an arm rigidly mounted on said shaft a plate mounted on the conventional foot accelerator pedal or parts leading to the throttle valve of the carburetor and adapted to be engaged and moved forward by said arm.

2. A foot accelerator including a housing, a slot provided therein, a foot lever fulcrumly mounted in said housing, a stud secured to one end of said foot lever and adapted to travel in said slot, a roller provided with a flange extending around its base and mounted on the upper end'of said stud and adapted to turn thereon, a sector provided with teeth and to whichsaid foot lever is secured, a shaft and a pinion rigidly secured thereto and adapted to mesh with the teeth of the sector, an arm rigidly mounted on said shaft, a plate mounted on the conventional foot accelerator pedal or parts leading to the throttle valve of the carburetor and adapted to be'engaged and moved forward by said arm.
