Application filed January .19, 1923. Serial m-.-e1s,7s5.

T 0 all whom it may concern: 7

Be it known that I, PLnAs E. VINEYARD, a citizen ofthe United States, residing at Windom, in the county of F annin and State 5 of Texas, have invented new and usefullmprovements in Accelerators, of which the tollowingis a specification.

This invention relates to improvements in motor driven vehicles and has especial relation to means for controllingthe supplyof fuel to internal combustion engines, an object being to provide toot operated means for this purpose which is especially designed for application to automobiles of the well known Ford make. 7

Another object of the invention is the provision of a foot accelerator which may be attached by means of the bolts already present in the automobile mechanism, so that the services of a skilled workman or mechanic will be unnecessary for the application of the invention. I

Another object of the. invention isthe provision of means included in the accelerae tor structure, whereby the foot pedal may be operated without moving the hand throt tle lever, novel means being provided for attaching the device to the throttle-valve,

controlling arm of the this purpose. I a

Another object of the invention is the provision of means whereby the usual rod which connects the hand lever rodto the carbureter, may be adjusted, so as toproperly control the operation of the throttle valve with the hand lever.

With the above and other objects in engine earbureter for view,

the invention further includes the follow-I ing novel features and details of construction, to be hereinafter more fully described, illustrated in the accompanying drawings and pointed out in the appended claims.

In the drawings 2-- Figure 1 is a plan view showing a fragmentary portion of an automobile mechanism and a portion of the floor of the automobile.

Figure 2 is a fragmentary side view of the same with the portion of the floor shown in Figure 3 is a detail plan view illustrating the means of connecting the foot accelerator pedal and the hand lever with the arm of skilled wo-rl'n'nan for its attachment.

this purpose there is provided a plate the carbureter throttle valve, the parts be ing in normal position. o Figure 4 1s a view similar to Figure :8

showing the position or the parts when the I throttle valve is operated by the hand lever.

I Figure 5 is a like view showing the posi tion of the parts when the throttle valve is operated by the foot pedal.

. Figure 6 is a detail plan view illustrating the manner of attaching the hand lever rodv to the carburetor connecting rod.

F igure 7 1s a section on the line 7-7 of F igure 6.

Figure 8 is a detail side elevation partly broken away showing the manner of mountmg the bearing plate for the rock shaft.

,Figure 9 is a fragmentary view illustrating the manner of connecting the foot pedal with the rock shaft. 7 Figure 10 is a. fragmentary plan view of one end of one of the bearing plate supportmg arms. a r p I Figure 11 is a detail perspective view of the clamp which is attached to the throttle valve operating arm and showing the rigid arm carried by this clamp.

Figure '12 is a detail perspectiveview of the pivoted arm.

I Figure l3'is a section taken substantially onv the line 13+-13 of Figure 4.

15 indicates a portion of the housing-of an:

internal combustion engine, which is supported upon side bars 16'of the frame of the automobile, while 11 indicates the transmise slon case which is located between the fioor 18 of the auto-mobile body, the usual clutch,

reverse and brake pedals extending upward ly throughthis floor as shown at 19.

The present invention provides foot operated means for controlling the carburetor throttle valve, which is mounted so as not to require the services of a mechanic. or

which is disposedtransversely beneath the floor 18 and which has secured thereto as shown at 21, one end of an arm 22. The opposite'end of this arm is secured upon one of the screws: or bolts 23 which serve to secure the cover of the transmission case 17 in place and for this purpose, the arm 22 is: provided with two openings one or which may be brought into position for re ceiving the screw or bolt 23 of the late model Ford automobile,'while the other is designed for use with previous models. The connection 21 between the arm and the plate 20 is therefore pivotal. Rlgldly secured to the plate 20 is one end ofan arm" 25, while the opposite end of this arm is notched as at 26 so as to receive one of the bolts 27 of the engine head.

The plate 20 is provided with spaced bearin gs 29 within which is mounted a rock shaft 30, the said sh att carrying at one end a crank arm 31. Adjustably secured to the opposite end of the shaft 30 as shown at 32 is a foot pedal 33 which extends upward through a slot 34- provided in the floor 18, the adyush able securing means 32 providing conven1ent means for properly positioning the pedal 33 upon the rock shaft to insure proper operation of the parts.

The engine carbureter which is of the ordinary construction is indicated at 31 and is pr vided with the usual operating arm 35 which is rigidly secured to the stem 38 0? the throttle valve. The arm35-is provided at its free end with an opening 37 which ordinarily receives one end of a connecting rod 38, but in the present invention this rod isremoved and a bolt 39 is positioned in the opening 37 which serves as an attaching means for a clamping arm 40. The arm 40 has extending downwardly from opposite side edges fingers or lugs 41, whicl'i engage the opposite sideedges of the arm 35 and act to hold the clamping arm 40 rigid with respect to the throttle valve operating arm 35.

The free end of the clamping arm 40 carries a substantially L-shaped rigid arm 42 which is provided at its outer end with an opening 43 for the reception of one end of a rod let, while the opposite end of this last mentioned rod is pivotal-1y secured to the outer end of the crank arm 31.

As thus far described, it will be apparent that with the parts in the position shown in Figure 3, a downward pressure upon the foot pedal 33 Will rock the shaft 30 and move the rod'es forward as indicated by the arrow 1n Figure 5 01": the drawings and thus actuate the throttle valve.

end of this arm is provided with a slot 47.

This-slot is adapted to receive one end of the rod 38 which is ordinarily connected to the rod 48 which has secured thereto the usual hand lever (not shown).

In order to accommodate the rod 38 for use with the present inven f on there is provided a plate 49 which is illustrated in Figure 6 of the drawings and which is provided with an opening 50 for receiving the end of the rod 38. This plate 49 is provided with a slot 51 for the passage of a bolt 52, which bolt serves to connect the plate 49 with the usual arm 53 which is carried by the rod 48, the plate 49 may thus be adjustable upon the arm to accommodate the rod 38 to the dili'crence between the connecting means of the present invention and that usually employed.

hen the hand lever (not shown) is operated to control the throttle valve, the rod 48 will be rotated in the usual way, which operation will move the rod 38 in the direction of the arrow shown in Figure a, whereupon the end of this rod which is connected to the pivoted arm as will engage the clamping arm 40 and operate the throttle valve. While the rigid arm 4:2 and consequently the foot pedal 33 will also be actuated, it will be apparent that the said foot pedal may be operated to control the throttle valve without actuatingthe hand lever.

The invention is susceptible of various changes in its form, proportions and minor details of construction and the right is herein reserved to make such changes as properly fall within the scope or" the appended claims.

Having described the invention what is claimed is 1. The combination with an automobile having an internal combustion engine, of a bearing plate extending transversely beneath the floor, of the automobile, an arm having one end connected to the plate and its opposite end secured to the engine, a second arm also having one end secured to the plate and having its opposite "end secured to the transmission case for supporting the plate, rock shaft mounted in bearings carried bythe transverse plate, a foot pedal seeuredto the rock shaft and extending from the floor and means operatively connecting the opposite end of the arm to the throttle valve of the engine carbureter for operating said valve 7 a 2. The combination with an automobile having an internal combustion engine and a hand'lever for controlling the throttle valve. of the engine carbureter, of an arm rigidly secured to the throttle valve operating arm, a rock sl1al't,a foot pedal secured to the rock shaft, means operatively eonnect ing the rigid arm and rock shaft, whereby the throttle valve may be operated, an arm pivotally mounted upon the rigid arm securmg means, a rod having one end connected to the pivotally mounted arm and adjustable means connecting the opposite end of said rod with the throttle lever rod.
