FOOT ACCELERATOR.
Application filed November 8, 1921. Serial No. 513,670.
To all whom it may concern: Be it known that I, JOSEPH Milwaukee, in the county of Milwaukee and State of YVisconsin, have invented oer tain new and useful Improvements in Foot Accelerators; and I do hereby declare that the following is a full, clear, and exact description thereof.
My invention refers to foot accelerators and it has for its primary object toprovide a simple, economical and effective foot acceleratorattachment which will not vibrate or which will not be inadvertently operated by movement of the. foot. 7
Practice has demonstrated that foot accelerators of the plungeror rocker typewill frequently be inadvertently actuated by a pressure of the foot thereon when no move ment of the accelerator is desired.
A further objectionable feature of this type of accelerator is that even the jarring or moving of the vehicle will tend to shift the mechanism, whereby it will operate disadvantageously to the natural or desired function of the engine. i i
. My 1nvent1on 1s thereforeprimarlly developed to overcome these objectionable fea-' tures in thatthe arrangement andconstruc tion is such that the operator must perform' a distinct side swiping movement of the foot to bring the accelerator intoplay. Thus the other foot actions necessary in controlling the engine will not in any way affect the accelerator. I 1
With the above object in view, the accelerator includes, as an essential element, a horizontally shiftable button mounted directly upon the floor board of a vehicle in such a way that the operator must exert an ankle or horizontal swing of the foot from left to right to cause the accelerator to function, there being a spring inconnection with the actuating mechanism for returning it to normal.
The accelerator also includes means for effecting various adjustments and for op erating the carbureter either by footor by hand, the connectionto the hand operating mechanism and foot mechanism being constructed to permit movement of the foot accelerator independent of the hand actuating mechanism. 7
With the above and other minor objects in view, the invention consists of certain peculiarities of construction and combination v y F. Linen, a citizen of the United States, and resident of of parts as are hereinafter set forth with reference to the accompanying drawings and subsequently claimed.
In the drawings,
Figure 1 represents a plan view of a foot accelerator embodying'the features of my invention.
Figure 2, an enlarged detailed view of a link connection between the foot accelerator mechanism and the standard hand type of actuating mechanism with parts being broken away and in section to more clearly illustrate structural features.
Figure 3, an enlarged detailed cross section showing a coupling connection between the foot accelerator mechanism and the carbureter lever, whereby means of adjustment is effected, the section being indicated by line 3-3 of Figure 1, and
Figure 4, a cross section illustrating the longitudinal shiftable foot actuating button for shifting the carbureter by a horizontal movement, the section being indicated by line H of Figure 1.
Referring by characters to the drawings, A represents the carbureter or any standard type, B the actuating arm thereof to which is attached a link 1. The pivot connection between the link 1 and the arm B is preferably adjustable for fitting the parts to various standard mechanisms.
As best shown in Figure 3 of the drawings, the pivot connection between the link and arm is effected by an adjustable clip 2 which is slidably mounted upon the end of the link 1, the" said clip having a threaded ot connection thus effected is held intact by a pin 4, which passes through a suitable transverse aperture formed in the pivot stud 3. Hence it will be seen that the link can be adjusted forwardly or backwardly with relation to the arm 13 for the purpose of assemblage and for compensation with respect to the fixed position of the carbureter and a' hand controlled accelerator lever D. The said lever D is of a standard type and is mounted upon a shifting rod E.
The outer end of the link 1 is upturned, as shown in Figures 1 and 2 of the drawings, to form an apertured ear 1'. Loosely mounted in the apertured ear is a coupling rod 5, which rod is pivotally connected to the shaft rod 13;, and its opposite end is adoptedto have sliding engagement with the apertured ear 1. the end of the coupling rod, whereby suitable adjustment may be effected between the coupling rod and link. 1
By this construction, it will be seen that when-the link is moved in one direction, to shift the position of the carburetor by the foot accelerator mechanism, there is no movement imparted to the hand actuating mechanism, due to the fact that the sliding coupling connection between the link 1 and rod- 5 will permit the desired play.
i The link 1 is pivotally connectedto the outer end of a rock-arm 6, which rock-arm, in turn, is pivoted to a bracket 7 that is suitably connected to the vehicle frame. Thebracket 7 also carries a leaf spring 8,
which leaf spring impinges against one end 7 of the rock-arm and serves to forcibly return the carbureter arm to its normal position, after an accelerating movement has been effected either by the hand controlled mechanism or the foot controlled mechanism. The inner end of the rock-arm (3 has pivotally connectedrthereto, a horizontally movable foot bar 9. The end of the feather is bent at a right angle to the body thereof, forming a neck 9 which extends upwardly through a slot 10 in the obliquely disposed foot board F of the vehicle frame.
Secured by suitable screws over the slot 10 is a slotted bed-plate 11 through which the neck 9 extends, the same terminating of the link mechanism as a whole, whereby the carbureter is actuated to effect the desired accelerating movement.
From theforegomg description it will be 7 seen that the accelerator attachment can be readily and quickly affixed to any standard A nut 5 is in threaded union with type o f motor driven vehicle, and it is particularly adopted for Ford use, being simple in construction and so arranged as to permit of all the desired adjustments, whereby it can be, fitted to a vehicle Without the aid of a skilled mechanic.
to such chatter o'r vibration, which vili'ration is common in the ordinary type of accelera tlon, where the vfoot actuating mechanism operates vertically and necessarily is under gravity controlled in one direction.
7 While I have shown and descrlbed one simple, exemplification "of my invention minutely as to .allstructural features, it is "understood that the same may be varied within the scope of the claim. .I claim: I.
In an automobile the combination vof carbureter having a rock arm, a link connected thereto, a coupling rod slidably joined to said link and forming an exten sion thereof and adapted to -slide freely in one directionand to operatively engage the link when moved in the other direction, a shift rod, an arm carried by said shift red and pivotally joined to said'couplingroc, a
foot bar having a lateral extension adapted to be operatedby lateral movement of the drivers foot, an elongated rock arm pivoted mterlnedlate lts ends and directly'connecting and pivotally joined to said foot bar and said linlgand a spring for rocking said rock arm in one dlrectlen.
In testimony that I claim the foregoing-I V have hereunto set my hand at h lil'wa'ulree in the county of Mllwaukee and State of Wisconsin;
