CAR-MOVER- Specification of Letters Patent.

Patented July 10, 1906.

Implication filed March 29. 1906. smai No. 308,746.

To KLZZ whom, it natty concern:

Be it known that I, LEO EHRLICH, a citi- Zen of the United States, residing at St. Louis, Missouri, have invented a certain new and useful Improvement in Oar-Movers, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in which Figure 1 is a side elevation of a car-mover embodying the features of my invention.

Fig. 2 is a detail view showing the position of the wheel-engaging shoe after the carwheel has been moved forwardly, a portion of the frame being broken away to more clearly show the operation of the parts; and Fig. 3 is a sectional View on the line 3 3 of Fig. 2.

This invention relates to carn1overs, and particularly to that type shown in Patent No. 762,901, granted June 21, 1904, to R. F. Hageman and J. E. Hageman.

The car-mover shown in the patent referred to consists principally of a frame in which is pivotally mounted a shoe that is actuated by a lever for engaging the carwheel which is being operated on, and said frame is provided with a heel-piece formed separate therefrom and having toothed bits which engage the sides of the tread of the rail on which the car-wheel rests to hold said frame in place when pressure is applied to the actuating-lever.

The object of my invention is to provide a car-mover of simple construction comprising a frame having rail-gripping members connected thereto, which members are auto matically forced out of gripping contact with the rail when the actuating-lever is relieved from pressure and which are held in an inoperative position until pressure is again applied to the actuating-lever, so that the oar-mover can be slid forwardly on the rail without liability of dulling the rail-gripping members.

Another object of myinvention is to provide a car-mover in which the friction between the shoe and the actuating-lever is reduced to a minimum.

Other desirable features of my invention will be hereinafter pointed out.

Referring to the drawings, which represent the preferred form of my invention, 1 designates a skeleton-like frame consisting of two side standards having a wheel-engag ing shoe 2 pivotally connected thereto by a pin 3, said frame being provided at its forward end with a toe-plate 4, having depend ing ears 5, which embrace the sides of the tread of the rail. A lever 6 is pivotally connected to the frame by a pin 7, and a roller 8 is mounted in the forward end of said lever for engaging a straight face 9, formed on the underneath side of the shoe 2 to swing said shoe upwardly when the outer end of said lever is depressed. The lower end of said straight face 9 terminates in a tooth 10, and the shoe is provided with lugs 11, which rest on the frame when the shoe is in normal position.

At the lower side of the rear end of the frame 1 are a pair of toothed gripping-bits 12, which are rigidly connected to the frame by bolts 13 and which are adapted to bite into the sides of the tread of the rail when pressure is applied to the actuating-lever 6. A rearwardly-extending yoke-shaped member 14 is pivotally mounted on the pin 7, which connects the lever 6 to the frame, and a roller 15 is mounted in the lower end of said yoke-shaped member, said roller conforming to the tread of the rail and being adapted to rest thereon. A spring 16, which is connected to the frame by a pin 17, extends beneath the pin 7 and around the upper end of one leg of said yoke-shaped member and is provided with an extension 18, which projects into a hole formed in the yoke-shaped memher. The force of said spring holds the roller 15 of said yoke-shaped member on the rail and tends to draw said member toward the frame 1, thereby causing the rear end of said frame to be elevated for holding the bits 12 out of biting contact with the tread of the rail, said frame swinging upwardly on the toe-plate 4 as a fulcrum.

In operation the car-mover is slid along the track until its shoe comes into contact with the periphery of the car-wheel 19, and then the outer end of the lever is pressed downwardly, thereby causing the roller 8 to engage the straight face of the shoe and swing it upwardly into the position shown in Fig. 2 to move the car-wheel forwardly. The downward pressure on the rear end of the actuating-lever causes the rear end of the frame 1 to be depressed, so that'the bits will bite into the sides of the tread of the rail and prevent the frame from moving rearwardly away from the wheel being operated on. WVhen the lever is moved upwardly to normal position, the shoe drops back into its normal position and the force of the spring 16 draws the yoke-shaped member toward the frame, so that said frame is raised slightly on the toe-plate 4 as a fulcrum, the upward movement of the frame carrying the bits out of engagement withthe tread of the rail and enabling the car-mover to be slid forwardly on the rail to carry the shoe into engagement with the wheel again.

Preferablythe lever 6 is bent upwardly at 20, as shown in Fig. 1, so that when it is moved downwardly the outer end will not come into contact with the rail, the bend in the lever being so located that the lever does not engage the brake-beam 21 of the car.

It will thus be seen that I have produced a car-mover of simple construction comprising very few parts and in which the friction between the actuating-lever and wheel-engaging shoe is reduced to a minimum.

Having thus described the invention, what is claimed as new, and desired to be secured by Letters Patent, is i 1. A car-mover comprising a frame, a wheel-engaging shoe pivotally connected to the frame, a lever pivotally mounted on said frame for actuating said shoe, means con nected to the frame for grippin a rail, and means for normally holding t e gripping means out of engagement with the rail, substantially as described.

2. A car-mover comprising a frame, a

wheel-engaging shoe pivotally connected to the frame, a lever carried by said frame for actuating said shoe, devices connected to the frame for gripping a rail, and automatically- I operable means for normally forcin the said devices out of gripping contact wit the rail when said actuating-lever is relieved from pressure, substantially as described.

3. A car mover comprising a frame, means carried by the frame for gripping a rail, a wheel-engaging shoe pivotally connected to the frame, a pivotally-mounted lever carried by said frame for actuating the said shoe, and a spring for normally holding the said gripping member out of engagement with the rail, substantially as described.

4. A car-mover comprising a frame, means carried by the frame for gripping a rail, a wheel-engaging shoe pivotally connected to the frame, a pivotally-mounted lever carried by said frame for actuating said shoe, a yokeshaped member projecting rearwardly from the frame and provided with a roller for bearing upon the tread of the rail, and a spring connected to the frame and to said yokeshaped member for exerting a downward pressure on said member and drawing it toward the frame; substantially as described.

5. A car-mover comprising a frame, means rigidly connected to the frame for gripping a rail, a wheel-engaging shoe pivotally connected to the frame, and a lever pivotally mounted in the frame and provided at its forward end with a roller which engages said shoe and actuates it as said lever is depressed; sub stantially as described.

In testimony whereof I hereunto affix my signature, in the presence of two witnesses, this 26th day of March, 1906.

LEO EHRLICH.
