THROTTLE CONTROL FOR AUTOMOBILES.

l Specification of Letters Iatent'.

lljatenteol Aug. 2e, 1915.

Application filed November 25, 1913. Serial No. 803,002.

To al@ fils/ima, it 'may oonecriz Bc it known that l, WALLACE E. MORGAN, a. citizen ot the United States, residing at Geneseiii, iu the county ol' Henry, State of lllino's, have invented certain' new and uselul improvements in Throttle Control for Automobiles; and l do hereby declare.the following to be a full, clear, and eXact description of the invention, such as lwill enable others skilled in the art towhich it appert i to make and use the same.

This inventioii relates to improvements in engines, and particularly gas engines .sed on automohi` rllhe principal object o the invention is to noi'irle a throttle or intake valve which'can operated independently by the foot or rand o'li the driver oll the car.

Another object is to provide hand and foot actuated means for moving` lthe throttle valve each of which can be operated without interference olZ the other.

@ther objects and advantages Willbe apparent from the ofiwing description, when t: hen in connectie*l with the accompanying ln the drawings: Figure 1 is a fragmentary sect 'in an automobile showing',` my invention in elevation. Fig. 2 is a 'top plan View oli the. de .ice Fig'. 3 is a rear elevation of the parts of my invention in their proper relative positions but detached from the;y automobile, Fig. 4- is a vertical section on the line of Fig. 2.

Referring particularly to the accompanying drawings, 10 represents a `transverse shaft suitably mounted below the inclined` floor board 1l of the automobile. (larried by one end ot the shaft 10 is a vertical exblade 12 which projects through an opening;l lit in. said floor board. At the opposite enol of the shaft is a. downturned arm 13, the lower end of which has an aperturcd head 15 which receives slidably therethrousi'h one end` of a connecting rod 16, 'to .vhieh iurther reference will be made hereinafter. The rear end of this connect, ing rod is threaded and carries an adjusting nut 17 wiich is rrangeel to limit the forward sliding; movement of the rod through 'the head 15.

The carhur i., is located. at the proper point and h ie. air intake pipe 19 at one side. aneia pipe. 2li at the other side which leads the rr'i'old ol" the engine cylinnot sI i this pige mounted the usual throttle gate or butterfly valve 2r, and carried by the outer end ot one of the trunnions` 22 of said gate or valve is an arm 23. Secured to this arm is an lirregularly shaped plate 24,' this plate having the forward end of the beorementioned connerting rod 16 connected to an intermediate portion thereof, as indicated at Connected to the forward portion of. the plate and to the outer end of the arm 23 is a wire cable 26 which leads to the hand throttle lever on the steeringr Wheel. not shown. This conne@ tion of the wire 26 with the throttle lever the usual arrangement. and it is thought necessary to illustrate the saine. the real lower portion oi the plate 2l are formed a series et' openings 27, and engaged in one of these openings is one end ot) a. coiled spring 2S, the other end of this spring heine suitably anchored to any convenient point on the car. T he forward end oiE this spring is arranged 'For interchangeable engagement in the openings 27, so that the tension of said spring' can be regulated.

1When the wire 2G is pulled by han@ throttle lever, the plate 2l. will rotate the valve 21 against the tension ot the s 28, and open `the said val ve. lll/heu tension is released from the wire 2G, the spring will draw the plate back into normalposi' tion to close the valve.

To adapt the device for operation by the foot, I provide the pedal 12. Upon forward; pressure ot this pedal, the shaft 1G will be rocked so that the arm 14 will be thrown rearwardly. The head 15 will then engage against the adjusting` nut 17 and pull the connecting rod 16 reaiwvarflly.y thus rocking tho plate 24 and operating r' y. mlve 21 as before described in connection with he Wire 26. By arranging' the rod 1b to slifle through the head 15 permits of the moving of the valve by the wire 2G Without disturbing the position of the pedal 12 or rocking the shaft 10, as th i said rod will slide idly through the head.

From the'foregoing, it will readily b that I have provided a simple, cheap eicient device whereby the intake val throttle can be readily operated by ther the foot or hand of the driver of the oar, Without interference ot one operating meche anism to that ot the other. it fill also be noted that by moans oli the adjustii :uit the throw of the connecting' roti can lated so that the valve 21 can be opened auf' ve or greater or lesser degrees. Also, by providing means for adjusting the forward endv oi*I the spring 2S', the valve 2l can be made to close more or less rapidly.

-`What is claimed is:

l. The combination in a device of the character described including an intake pipe, of a gate within saidk pipe having a projecting trunnion, a plate secured to said trunnion, a. foot-operated shaft having` a crank arm, a connection extending from said arm to said plate having its end secured to said plate at a point in advance -of said trunnion and a spring to Anormally close said gate, said shaft adapted to actuate said plate, and means to impart a 'movement to said plate independent of said shaft.

2. The combination with a carbureter air intake pipe and an air valve mounted therein, of an approximately triangular operating crank plate, having its side connected lto the valve outward-ly oit the pipe, operating rods pivoted to the crank plate at epposite ends of the base 'thereol and extending in directions therefrom approximately at 25 r1 ght angles to each other, a pedal connected direction only, Vand a spring connected to 30 the crank plate at the apex thereof arranged to return and `hold the plate normally 1n positlon to close the valve.

In testimony whereof, l aiix my signature. 1n the presence of two witnesses.
