This invention appertains to new and useful improvements in governor controls for trucks and other vehicles whereby the full power of the low gears and reverse can be utilized without overriding a predetermined limited speed.
The principal object of the present invention is to provide a governor control for trucks and other vehicles whereby acceleration is controlled by a governor actuated by the driven shaft of the vehicle drive line.
Other objects and advantages of the invention will become apparent to the reader of the following specification.
In the drawings-- Figure 1 represents a fragmentary sectional view showing the governor and the fuel control valve.
Figure 2 is a vertical sectional view through the governor structure.
Figure 3 is a sectional view on the line 3-3 of Figure 2.
Figure 4 is a fragmentary detailed sectional view on the line 44 of Figure 2.
Figure 5 is a top plan View of the governor structure.
Figure 6 is a sectional view on the line 66 of Figu e 5.
Figure 7 is a fragmentary side elevational view of the link structure.
Figure 8 is a perspective view of the valve driving shaft with the sections separated.
Figure 9 is a sectional view through the valve structure.
Referring to the drawings wherein like numerals designate like parts, it can be seen in the drawings, that numeral 5 generally refers to an internal combustion engine. Numeral 6 is the intake manifold to which the carbureter pipe 1 extends. Interposed between the pipe 1 and the manifold 6 is the hollow section 8 having the horizontally disposed grooveway 9 therein for receiving the edge portion of the throttling slide valve l0.
Numeral ll represents a shell flanged as at l2 and secured to the pipe 1 and manifold 6 and adapted to abut the section 8. The outer end of this shell H is provided with a header I3 suitably secured to the shell and through which extends the shaft [4.
An inclined plate 15 reinforced by webs I6 is formed on to the outer end of the valve plate In and engaged with this inclined plate I5 is the inclined plate 11 of the pusher unit 18, the latter being carried by the shaft 14 and adapted to rotate therewith.
The shaft l4 has one end apertured as at [9 and extends into the hollow end of the elongated shaft 20. The shaft 20 has an opening 2| therein and through this opening 2| and the opening 19 in the shaft M a cotter key 22 can be disposed.
The opposite end of the shaft 20 is tapered as at 23 for disposition into the tapered and polygonal-shaped opening of the block 24, this block 24 having a neck 25 extending therefrom merging with the arcuate-shaped head 26 having the arcuate-shaped slot 21 therein.
The shaft l4 extends into the housing 28 at one side thereof, while extending through the top of the housing 28 is the slidable shaft 29. Numeral 30 represents the riser flanged as at 3| at its lower end for attachment to the top of the housing 28. Numeral 32 represents the governor sleeve having the gears 33 at its lower end. Interposed between the gears 33 and the flange 3| is the bearing assembly 34.
Upstanding and diverged arms 35 rise from the sleeve 32 and the upper ends of these arms are bifurcated as at 36 for receiving theheel portions 31 of the angularly-shaped governor arms 38, the heel portions being fulcrumed in place as at 39 in the said bifurcated portions 36.
A grooved collar 40 is provided on the upper portion of the shaft 29 and the upper ball-shaped ends 4| of the arms 38 terminate within the groove of the collar 40.
A link 42 pivotally connected to the lower end of the shaft 29 has a roller 43 mounted on its lower end, this roller operating in the slot 21 of the head 26. A coiled tension spring 44 is interposed between the head 26 and the top of the housing 28 to normally hold the parts in the position shown in Figure 2.
Bearing blocks 4545 are mounted on the top of the housing 28 and each is provided with an externally threaded tubular extension 46 to which a flexible shaft conduit can be attached. Extending through the bearing blocks 45 are the socketed pintles 41 extending from the worm gear 48, this worm gear meshing with the gear 33 of the governor structure shown in Figure 2.
The flexible shaft 41 is engaged with one or the other of the pintles 41 and is driven from the driven shaft side of the usual vehicle transmission (not shown).
While the foregoing specification sets forth the invention in specific terms, it is to be understood that numerous changes in the shape, size and materials may be resorted to without departing from the spirit and scope of the invention as claimed hereinafter.
Having described the invention, what is claimed as new is:
1. A control mechanism of the character described comprising a reciprocatory drive member, a driven shaft, said shaft being divided into a pair of sections, one of said sections having a recess therein for receiving the adjacent end of the other section, the recessed shaft section being provided with a tapered end, a block having a tapered polygonal-shaped recess therein for receiving the tapered end of theshaft section, a screw disposed through the block and into the tapered end of the shaft section, and a pivotal connection between the reciprocatory member and the block, said block including a neck portion and a transversely extending. and arcuate head portion formed with an arcuate slot. said pivotal connection comprising a link member pivotally connected to the reciprocatory member and having a laterally disposed portion disposed into the slot of the block head.
2. A control mechanism of the character described comprising a reciprocatory drive memher, a driven shaft, said shaft being divided into a pair of sections, one of said sections having a recess therein for receiving the adjacent end of the other sections, a. block attached to the remaining end of the recessed shaft, a pivotal connectionbetween the reciprocatory member and the block, said block including a neck portion and a transversely extending arcuate-shaped head portion formed with an arcuate slot, said pivotal connection comprising a link member pivotallyconnected to the reciprocatory member and having a laterally disposed portion projecting into the slot of the block head.
