Application filed July 28, 1924. Serial No 728,668.

To all whom it mag concern:

Be it known, that 1, WILLIAM W. SCHNELLE, a citizen of the United States, residing at Chillicothe, in the county of Livingston, Stateof Missouri, have invented certain new and useful Improvements in Accelerators for Gas Engines; and I do 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 new and useful improvements in automobile engine devices, and particularly to control devices therefor.

One object is to provide a simple and cheap device by means of which the flow of gas can be regulated by the foot of the driver. This is especially adapted for certain types of automobiles which do not have foot con trols.

Another object is to provide a device of this character which is adapted to permit the control of the gas by the ordinary hand device, or by the foot device, each being arranged to operate without interfering with the operation of the other.

A further object is to provide a device of this character which can be easily and quick- 30 1y applied to certain types of automobiles without modifications thereto.

Other objects and advantages will be apparent from the following description when taken in connection with the accompanying as drawing.

In the drawing: Figure 1 is a fragmentary sectional view of a portion of an automobile showing the invention.

Figure 2 is a top plan view of the same. Figure 3 is a vertical transverse sectional view on the line 33,v of Figure 2.

Referring particularly to the accompanying drawing, 10 represents the steering column of an automobile, which has the collar 11 thereon provided with the opposite lateral apertured arms 12 and 13 which rotatably support the spark and gas rods 14 and 15, respectively. On the gas rod 15 there is 59 fixed a depending arm 16 which has an eye 17 in its lower end. In the footboard 22, of-

the automobile, there is mounted an apertured plate 23, which registers with an opening 2A in the footboard, and through the openings of the footboard and plate a rock shaft 25 is disposed, the end which projects rearwardly of the footboard being turned downwardly, and provided with a cushion sleeve 26, for engagement by the foot of the driver. The forward end portion of the rock shaft 25 is turned downwardly as at 27 and then upwardly as at 27, whereby to form the eye 28. The free end of the portion 27 is then passed through the eye 17 and directed upwardly. The angularly turned end 18 of the link 19 is engaged through this eye 28, this link being connected at its other end to the arm of the throttle, not shown, and secured in place by the coil spring 29. Engaged through an opening 30, in the link 19, is one end of said coil spring 29, said spring having its other end secured to a bolt or otherv suitable portion of the engine frame, whereby to exert apulling action on the shaft 25-t0 rock same into position to hold the throttle'in closed position. 7 I

The sleeve carrying end of the rock shaft 25 is disposed in such relation to the upper face of the footboard of the automobile, that the driver can engage the said end with the side of his foot, while his foot rests comfortably on the fo'otboard, thereby obviating any lifting of the foot to'operate the accelerator. Upon rocking the shaft 25 the turned forward end thereof pulls on the link 19, causing the throttle to be opened to a degree commensurate with the degree of rocking movement of said shaft. Upon removing the foot from the sleeved end of the rock shaft, the spring 31 will restore the shaft to its normal position, and close the throttle. When the throttle is to be operated by hand, the usual gas lever, on the upper end of the rod 15, but not shown in the drawing, is swung to rock the said shaft 15, whereupon the arm 16 will swing carrying with it the forward end of the rock shaft 25, and the attached end of the link 19, with the result that the throttle is opened.

It will be particularly noted that the operation of the rock shaft, to open or close the throttle, does not cause any movement of the arm 16, whereby the hand control of the throttle is unaffected by the foot control. Also, when the hand control is operated, the rock shaft is moved bodily, with the arm 16, and is not rocked, thus permitting either hand or foot control of the throttle without interference of the one by the other.

The application of this device to certain types of automobiles is accomplished ithout modifications to the automobile.

\Vhat is claimed is:

5 The combination with the gas rod having the lateral arm, and the throttle valve link of an automobile engine, of a bracket loosely carried by the gas rod, a rock rod havin a foot-piece on one end and having 10 its 0t ler end rotatable in said lateral arm,

said rock rod having an angularly extending arm operatively connected With said throttle valve link, and an extension on the rock rod extending in a direction diametri- Cally opposite to the angular arm and arranged to rest against the said gas rod whereby to limit rocking movement of the rock rod in one direction.

In testimony whereof, I aflix my signature.

WVILLIAM W, SCI-INELLE.
