SPECIFICATION formingpart of Letters Patent N 0. 689,659, dated December 24, 1901.
Application filed December 26, 1900. Serial No. 41,020. (No model.)
To all whom it may concern:
Be it known that 1, WILLIAM EDGAR STIR- LING, a citizen of the United States, residing at Mount Wilson, in the county of Baltimore and State of Maryland, have invented certain new and useful Improvements in Autovehicles, of which the following is a specification.
This invention relates to improvements inspeed-gear forautovehicles; and it consists of the new and novel parts and combination of parts hereinafter more fully set forth and claimed. 7
In theaccompanying drawings, Figure 1 is a side elevation, partly in section, of a car truck and frame with my invention applied thereto. Fig. 2 is a plan View of same, the driving-shaft being broken away. Fig. 3 is a detailed View of one of the friction-wheels, which are keyed to the axle of truck. Fig. 4 is a detailed View of the two wheels mounted on'the shaft to be driven, one of which is in section and showing the mechanism for reversing same.
For the purpose of illustration 1 have shown. my invention applied to a car-truck and actuated by a gas-engine; but the same may be applied to other vehicles and may also be actuated by steam, electricity, or any other suitable power.
Referring to the accompanying drawings, 1 designates the cylinder of a gas -engine, having a piston 2 connected to the shaft 3 to actuate the latter. On each end of'the shaft 3 is a fiy-wheel 4, each of which is provided with a crank-pin 5, to which are secured one end of the rods 6, through which a recipro cating or rocking motion is imparted to the arms 7. The said pins dare set at right angles or ninety degrees with respect to each other. The opposite ends of the said rods 6 are pivoted to the upper ends of the rock-arms 7, which latter are mounted in the bearings 8, secured to the front .of'the truck-frame. The lower-halves ofuthe rock-arms 7 are provided with dovetailed slots 9, in which are vertically movable the pins 10. The rods 11 have their front ends loosely fitted over the pins and their rear ends pivoted to the pendent rods 12. The rods 13 are secured by one end to the pins lO;a nd by the other ends to the rods 14, which latter are keyed to the shaft 15.
When it is desired to raise the front end of the rods 11 to shorten the-stroke, the lever 16, which is also keyed to the shaft 15, is pulled back toward the rear of the truck, which movement turns the shaft 15, raising the rods 14 and 13, causing the pins 10 to move upwardly in the slots 9, carrying with them the front ends of the rods 11, thereby shortening the stroke of the said rods, and consequently diminishing the speed of the vehicle being driven. The shaft 15 is mounted in bearings 40 on each side of the truck-frame.
The pendent rods 12 are loosely secured by their upper ends to the shaft 17 and are free to reciprocate thereon. To the lower ends of the said rods 12 are pivoted the front ends of the rods 18 and 19. The rear ends of the rods 18 and 19 are pivoted to the outer ends of the bifurcated shoes 20 and 21, respectively. The inner ends of the shoes 20 and 21 are fitted over and are revoluble on the axle 41 of the vehicle driven and are provided with lugs 22 to fit Within the grooves of the wheels 23 and 24.
To the axle 41 is keyed the wheels 23 and 24, each side of which latter is provided with. annular grooves 25, in which the lugs 22 project. Between the wheel 23and shoes 20 and also between the wheel 24 and shoes 21 are placed friction- rollers 26 and 26, the ends of which project through the slots 27 in the sides of the shoes 20 and 21. The facing surfaces 28 of the shoes 20 and 21 are inclined from the center outward, as indicated by dotted lines in Fig. 3, for the purpose hereinafter set forth. Projecting through the shoes 20 and 21 are pins 29, to which are secured the bellcrank levers 30, one arm of which latter projects between the two friction- rollers 26 and 26 and to the other arm is pivoted the rod 31. The rods 31 project down through lugs 32 on the sides of the shoes 20 and 21 and at the lower ends are provided with rollers 33.
On the axle 41 is loosely fitted asleeve 34, having at each end earns 35, on which the rollers 33 reciprocate when the axle is traveling forward. In the center of the sleeve 3is a lug 36, to which is pivoted a rod 37, which latter is connected to the lower end of the le-,
ver 28, by means of which the said sleeve 34 is peated over and over again.
The operation of the device is as follows: The shaft 3 is driven by the piston 2 of the gasengine cylinder 1. A reciprocating motion is transmitted through the shaft 3, rods 6, rockarms 7, rods 11, 12, 18, and 19 totheshoes 20 and 21. As these shoes move back and forth the rollers 26 on one side of the inclined faces 28 are gripped between said incline faces of the shoes and wheels 23 and 24, which latter are keyed to the axle of the vehicle to be driven, thereby causing the said wheels 23 and 24, and consequently the said axle, to be revolved in one direction. The said shoes act on the wheels as follows: The upper shoe 2O pulls on the wheel 23 for part of the revolution of the latter, then the lower shoe 21 pushes the wheel 24, the lower shoe 20 then pushes the wheel 23, and, lastly, the upper shoe 21 pulls the wheel 2t, the same action being re- The crank-pins 5 are arranged at right angles to each other, whereby one of the pins will always be in advance of the other one-quarter of a turn. \Vhen it is desired to reverse the action of the axle on the vehicle to be driven, the lever 38 is pushed forward, which through the me dinm of the rod 37 and lug 36 turns the sleeve 3* until the cams 35 are out of engagement with the rollers 33, whereby the rods 31 through the action of the springs 39 are forced downward, and by means of the bellerank levers 30 the rollers 26, formerly in engagement between the shoes 20 and wheel 23 and shoes 21 and wheel 24, will be thrown out of engagement and the rollers 26 on the opposite sides of the inclined faces 28 will be brought into play and reverse the action of the said shoes 20 and 21 on the wheels 23 and 24, and thereby cause the axle 11 to be revolved in the reverse direction from that above described for driving the vehicle forward. \Vhen the lever 16 is in the position shown in the accompanying drawings, the greatest speed is being obtained. \Vhen it is desired to decrease the speed, the lever 16 is pulled backward toward the rear of the truck, which turns the shaft 15 and rods 14, causing the rods 13 to pull the pins 10 upward in the slots 9, carrying with them the front ends of the rods 11 and bringing the latter nearer the center of the rock-arms 7. It will be seen that the nearer the front ends of the rods 11 are brought to the center of the rock-arms 7 the shorter the stroke of the rods 11 willbe. Consequently the speed of the vehicle will be decreased without decreasing the speed of the shaft 3.
It will be seen that instead of the smoothsurfaced wheels 23 and 2d a ratchet-wheel may be used and pawls used instead of the rollers 26 and 26.
Slight alterations in the construction and arrangement of the several parts as shown in the accompanying drawings may be made without departing from the spirit of the present invention.
Having thus described my invention, what I claim is 1. In a speed-gear for autovehicles,the combination of two friction-wheels rigidly secured to the axle to be driven; two shoes reciprocating on each of said wheels to revolve the latter; and means to impart a reciprocating motion to the said shoes, said means being so arranged that the shoes on one of the frictionwheels will always have a predetermined movementin advance of the shoes on the other wheel.
