THROTTLE-OPERATING MECHANISM.
Specification of Letters Patent.

Applicationfiled Marchgl, 1918. Serial No. 223,795.
To all whom it may concern:
Be it known. that we, Jon H. iLULr and JOHN T. HnA'roN, citizens of the United States, and residents of the city of Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Throttle-Operating Mechanisms, of which the following is a specification.
The invention relates to improvements in throttle operating mechanisms, especially adapted for use on Ford automobiles and arranged to permit of both hand and foot control of the throttle valve of the engine.
The invention consists in the combinations and arrangements of parts hereinafter described and claimed.
The invention will be best understood by reference to the accompanying drawings forming a part of this specification, and in which, V
Figure 1, is a sectional view illustrating an engine control embodying the invention in positionof use,
Fig. 2, a diagrammatic plan View of the engine control proper,
' Fig. 3, a detailed view of a control rod employed in the construction, and
i it of Fig. 3.
The preferred form of construction as illustrated in the drawings, comprises a control rod 5 operatively connected at one end with the throttle valve lever 6 of the carbureter 7 of the engine. A sleeve 8 is slidably mounted on the other end of rod 5 and a bell crank lever is pivoted at 8 on said sleeve, one arm, 9 of said bell crank lever being pivotally connected with one end of a link 10 having an eye 11 at its other end sliding freely on rod 5. The movement of eye 11 in one direction is limited by a cotter pin 12 passed through the rod 5 and a compression spring 13 is imprisoned between said cotter pin and the sleeve 8. The sleeve 8 is provided with a depending arm 14 which limits the swinging of the bell crank arm 9 on. one direction, and thus limits the movement of sleeve 8 on rod 5 in one direction.
The other arm 15 of the bell crank lever is connected by an operating rod 16 witha crank 17 and formed at one end of a crank shaft 18 equipped with bearings 19 arranged to be secured to the under side of the footboard of the automobile. Another crank 21 is formed atthe other end of shaft 18 and carries a foot pin 22 pivotally connected Fig. 4-, an enlarged section taken on line other.
therewith and arranged to operate through a hole in the foot-board 20 and by means of which the crank shaft 18 may be readily operated tooscillate bell crank 15 to operate the control rod' 5 to operate the throttle 6 of the carburetor 7. i
The sleeve 8 is provided with an integral extension 23 pivotally connected to one end of a pin 24: arranged to be pivotally connected to the free end of an oscillatory arm 25. fixed to the usual oscillatory shaft 26 mounted on the steering post 27 and assoiated with the steering shaft 28 of the au tomobile, said shaft 26 being equipped with the usual operating arm at the upper end of the steering post for controlling the throttle valve of the engine. By this arrangement oscillation of shaft 26 causes retraction of the sleeve 8, and consequently of rod 5 to operate the throttle valve of the engine, owing to the fact that the oscillation of lever arm limited by stop 14:, so that, in elfect, a rigid connection, is effected between said sleeve and rod 5 for movement in this direction.
will thus be observed that the throttle valve of the engine may be readily controlled lay manipulating the usual oscillating shaft 26 or by operating the foot pin 22 and that each operates independently of the The arrangement is such that the attachment may be readily substituted for the control rod now in use on Ford automobiles by a slight bend in the arm 25. with Which said automobiles are ordinarily equipped. The specific form of arrangement of parts is a simple and efiicient one for the purpose.
While we have illustrated and described the preferred form of construction for car rying the invention into eifect, this is capable of variation and modification without departing from the spirit of the invention. l Ve therefore do not wish to be limited to the precise details of construction set forth, but desire to avail ourselves of such variations and modifications as come within the scope of the appended claims.
Having described our invention, what we claim as new and desire to secure by Letters Patent is 1. The combination with the throttle of a carburetor of an engine, of a control rod attached at one end to said throttle; a sleeve slidable on the other end of said rod; a bell crank lever pivotally mounted on said sleeve; a link pivotally connected with one arm of said bell crank lever and slidable on said rod; a pin extending through said rod and limiting movement of said link thereon in one direction; a compression springimprisoned between said pin and said sleeve; a stop on of said arm of said bell crank; an operating rod pivotally connected with the other arm of said bell crank; crank shaft arranged to be mounted on the under side of the foo beard of an automobile and provided with a crank at each end, the crank at one end .bein' aivotall I connectedwithsaid oaera-tb i q ing rod a foot pin pivotally connected with the. other crank and arranged to operate through an opening in said foot board; asteering post for the automobile; an oscil latingshatt on said steering post; an oscillating arm on said shaft; and an operative connection between said oscillating arm and said sleeve, substantially as described.
2. The combination with the throttle valve of a carburetor of an engine of a control rod attached at one end to said valve; a sleeve 'slidabie on the other end of said rod; a bell crank lever pivotallv mounted on said sleeve; a link pivotally connected with one arm of said bell crank lever and slidable on said rod; means for limiting the movementof said-link thereon in one direction; a compression spring interposed on said rod between saidmeans and said sleeve; a stop on said sleeve limiting the movement of said arm of said bell crank; an operating rod pivotally connected with the other arm of said bell crank; pedal means for operating said sleeve limiting the movement substantially as described.
3. The combination with the throttle valve of a carburetor of an engine, of a control rod attached at one end to said valve; a sleeve slidable on the other end of said rod; a bell crank lever pivotally mounted on said sleeve; a link pivotallv connected with one arm of said bell crank lever and slidable on said rod; means for limiting the movement of said link "hereon in one direction; a compression spring interposed on said rod between said means and said sleeve; a stop on said sleeve limiting the movement of said arm of said bell crank; an operating rod pivotally connected with the other arm of said bell crank; pedal means-1 for operating the said rod; a steering post for the automobile; an oscillating shaft on said steering post; an oscillating arm on said shaft; and an arm integral with and extending from said sleeve and pivotally connected at one end with said oscillating arm, substantially as described.
In testimony whereof? we have signed our names to this specification in. the presence oi two subscribing witnesses.
