11 Claims. (Cl. 74-472) This invention relates to a carburetor throttle control and more particularly to the linkage used for actuating a carburetor throttle valve.
It is an object of this invention to provide a carburetor throttle linkage which is used to actuate a so-called butterfiy valve forming a part of the carburetor and is particularly adapted either under ordinary operating conditions or in overdrive as expediency requires.
It is another object of this invention to provide a carburetor throttle linkage that is more compact and easier to install than linkage of similar characteristics heretofore used. Linkages heretofore utilized presented an assembly problem of major importance in that when assembled in relation to the motor, toe board, and dash panel proper, they presented obstacles in the assembly of the body to the chassis. We contemplate, therefore, a carburetor throttle linkage arranged so that no obstacles are presented in the assembling of the body to the chassis. In addition We present a linkage which presents elements moving through a predetermined range with respect to actuating a butterfly valve in said carburetor which also provides a stop in said carburetor to present rotative movement of certain of said linkage elements and permit movement of other elements in said linkage to actuate an overdrive kick-down switch.
A further object of this invention is to provide a carburetor throttle linkage for a motor which is simple in design, economical to manufacture and easy to install in the ordinary motor vehicle.
We are aware of the various constructions heretofore used with respect to mounting carburetor throttle linkage in an internal combustion engine. Under the circumstances it will be manifest that it is our chief aim to generally improve upon prior structures of the general type by providing an arrangement characterized by appreciable .refinements and structural improvements.
' With our arrangement a great deal of time, labor, and loss due to damage is avoided. There is no opportunity of the linkage interfering or getting in the Way of parts of an automobile body being assembled on the chassis. Previously, the linkage would be damaged if care were not exercised and such linkage did present an obstruction causing interference and a source of irritation inthe final assembling. g
The several objects, advantages and novel details of construction of the invention will be made more apparent as this description proceeds, especially when considered in connection with the accompanying drawings, wherein:
Figure l is a plan view of an automotive vehicle with a portion of the invented subject matter disclosed in dotted lines.
Figure 2 is a side view of the apparatus as shown in Figure l. p
Figure 3 is a rear view of Figure 2.
Figure 4 is a top view in perspective of the invention as shown in Figure 2.
Referring to Figures -1 and 2, the invention is shown as it may be used on an automotive vehicle designated by the numeral showing the linkage L of the present invention in relation to the cylinder head C, the cylinder block CB and the clutch housing CH. The foot pedal 11, provided withpedal rod 12, extends through a toe board 13 where the free end of said rod is mounted on one end of a link 14. The other end of said link 14is mounted on one end of a link 14. Theother end of said link' 14 is mounted on one end of an operating'shaft 15 the invention as shown in 2,693,712 C6 iatented Nov. 5
which projects upwardly and is secured vertically by a bracket member 16. A second link or bracket member 17 is secured adjacent the top of said operating shaft and has an upwardly extending flange 18 apertured to receive an L-shaped ball joint 19 provided at its free end with an internally threaded section for threadedly engaging an operating rod 20. The rod has a section 21 intermediate its free end, upset, to provide a stop for a collar 22 which normally bears against the bottom end of a tension spring 23 encircling the space between said section 21 and adjacent the free end of said rod. The spring is held on said rod and prevented from sliding off said rod by a top plate 24 and pin 25.
The collar has a ball and extension 26 which moves within a ball socket formed within bracket 27. The free end of said bracket is secured to a part of the circumferential surface of an accelerator shaft- 28. In operation, therefore, as will be explained more fully hereinafter, rotative movement of the operating shaft will cause rotative movement of the accelerator shaft.
The accelerator shaft rotates at one end within a tubber bearing 29 which is mounted on bracket 30 secured to the dash panel 21. The free end of said accelerator shaft is formed in the shape of a hook which projects through apertures formed in a U-shaped extension 32. This extension has a short pin 33 which extends into carburetor 34 and actuates a butterfly valve (not shown) but of well known design. v
A coil spring 35 is secured at one end 36 to the bottom of the dash panel through any suitable fastening element 37. The other end 38 of spring 35 is mounted on a bracket 39 which in turn is anchored to accelerator shaft 28. In operation, therefore, the accelerator shaft rotates, the spring 35 expands and is under considerable tension enough to cause the accelerator shaft 28 to rotate back to normal position when the pressure on the pedal 11 is eliminated.
The linkage of the instant invention is particularly adaptable to mechanism provided with overdrive. The butterfly valve in the carburetor, and which is of well known construction, is provided with the usual accelerator shaft stop. This stop is arranged in the path of the pin 33 which is turned by rotative movement of the accelerator shaft. When the accelerator shaft has turned in approximately an degree arc, the stop engages the pin and prevents any further movement of the accelerator shaft. Continued pressure on the pedal moves the link 14 operating shaft 15 and link 17. The operating rod 20 still tends to push against the collar 22 but as the accelerator shaft 28 is locked against rotative movement beyond the 85 degree are, the collar rises up against the spring, sliding upwardly along the operating rod 20 and compressing the spring 23. Continued movement of link 17 after further rotative movement of the accelerator shaft 28 ceases, exerts tension on cable 40 which has one end secured to link 17 and the other end to an overdrive switch mechanism 41. When such tension is exerted on the cable 40, the switch 41 is actuated and the overdrive assembly is put in operation.
The action prior to the overdrive above is as follows. An operator depresses the foot pedal 11 thus forcing the pedal rod 12 to swing .the link 14 and accordingly rotates the operating shaft 15. The link 17, being secured adjacent the top of the operating shaft 15,. swings or rotates with the operating shaft. Movement of the link 17 pushes against the control rod which, being pivotally mounted at one end through ball socket joint 19 with the link 17, pushes against the collar 22 mounted on the operating rod 20. This movement against said collar 22 causes movement in the ball joint 26 connecting bracket 27 and collar 22. The collar 22 pushes against the bracket 27 and causes rotative movement of the accelerator shaft 28. Such rotative movement of the accelerator shaft has a range of 85 degrees as determined by the pin and stop in the carburetor before the overdrive condition takes place as described above.
It is thought that the construction, manipulation, utility, and advantages of this invention will now be apparent to those skilledin this art without a more detailed description thereof.
described in considerable detail merely for the purpose of exemplification since in actual practice it attains the features of the invention and the above description.
It will be apparent that changes in the details of construction, and in the combination and arrangement of parts may be resorted to without departing from the spirit or scope of the invention as hereinafter claimed or sacrificing any of its advantages.
