Application filed February 15, 1922. $eria1 No. 536,729.

To (ZZZ whom 2'13 may concern Be it known that l, Janus E. T'zirnon, a citizen of the United States, residing at Dallas, in the county of Dallas and State of Texas, have invented certain new and useful Improvements in Accelerators, of which the following is a specification.

This invention relates to an improved accelerator for motor vehicles and seeks, as one of its principal objects, to provide a de vice of this character which will be extremely simple in its construction while, at the same time, thoroughly eificient in prac' tical use.

A further object of the invention is to provide an accelerator which may be readily installed and which will afford thoroughly adequate foot control over the throttle valve of" the vehicle engine.

And the invention has as a still further object to provide an accelerator well adapted for a wid range of use.

Other and incidental objects will appear hereinafter.

In the drawing:

Figure 1 is a fragmentary side elevation showing my improved accelerator in connection with a Ford vehicle, parts being broken away and illustrated in section.

Figure 2 is a fragmentary perspective view bringing out the disposition of the foot pedal of the device, and

Figure 8 is a detail perspective view or" the device.

Referring now moreparticularly to the drawing, 1 have, for convenience, shown my improved accelerator in connection with a Ford vehicle. the device being especially adapted for use in conjunction with Ford automobiles, but not limited to such use. The vehicle engine is indicated at 10, the throttle valve lever of the engine carbureter at 11,

. and the front floor boards of the vehicle at 12. The dash is indicated at 13 and the vehicle steering post at 1%, the post being equipped with the usual collar 15.

' in carrying the invention into eilect, l employ brackets 16, one of which is, as shown in Figure 2, bolted to the dash 13 of the vehicle while the other of said brackets is secured by one or the bolts holding the collar 15. At their lower ends, the brackets are provided with bearings 17 and journaled at its ends in said bearings is a horizontally disposed pedal shaft 18 provided at a point substantially midway between its ends with a rearwardly directed pedal 19. This pedal is offset upwardly to treely project through a suitable slot in the floor boards 12 so that the pedal may be engaged for rocking the shaft 18. Depending from the shaft near one end thereof is an arm 21 and connected to said arm is a rod 22. Secured upon the engine 10 by one of the bolts holding the water inlet connection of th engine is, as particularly shown in Figure 1, an angle bracket 23 and pivoted upon this bracket is a bell crank 24. At its forward end, the rod 22 is provided with a downwardly directed terminal 25 engaged through one arm of the bell crank and connected at one end to the other arm of the bell crank is a rod 26. At its opposite end said rod is, as shown in Figure 3, engaged with the throttle valve lever 11 of the engine. Secured at one end to the terminal 25 of the rod 22 is a spring 27, the opposite end of which is engaged with an eyelet or other similar fastening device 28 sunk into the dash 13.

As will now be appreciated in view of the foregoing, the spring' 27 will act upon the bell crank 24 and lever 11 for normally holding the throttle valve closed. However, by depressing the foot pedal 19, the bell crank may be rocked for opening the throttle valve when, upon release of the foot pedal, the valve will be at once closed by the spring. ll accordingly provide device whereby the throttle valve may be readily manipulated and, as will be perceived. the device is ceedingly simple in its construction and may be easily applied.

Having thus described the invention, what is claimed as new is:

In an accelerator for motor vehicles, the combination of companion brackets for attachment to a vehicle dash at its inner side extending beneath the front floor board of the vehicle and provided at their lower ends with bearings open at their inner ends and closed at their outer ends by end walls, a rock shaft journaled at its ends in said bearings beneath the floor board and limited against longitudinal movement by said end walls, a foot pedal integrally connected to the shalt to extend rearwardly therefrom and offset upwardly near its outer end to rise through a slot in the floor board, an arm pivotally connected to the shaft near one end thereof to depend from the she.

at an acute angle with respect to said pedal, an angle bracket for attachment to the vehicle motor, a bell crank pivoted upon said angle bracket, a rod engageable at one end with the throttle valve lever of the vehicle motor and connected at its opposite end to one arm of the bell crank, a second rod connecting the other arm of the bell crank with the arm of said shaft and provided with a 10 laterally directed terminal engaging through the latter arm of the bell crank, and a spring for attachment at one end to the vehicle dash and engaged at its opposite end with said terminal securing the latter rod against disengagement from the bell crank and normally holding the throttle valve lever at the limit of its movement in one direction. 7

In testimony whereof I afiix my signature. 7
