CAR-MOVER.

SPECIFICATION forming part of Letters Patent No. 558,076, dated April 14, 1896. Application filed January 9, 1896. Serial No. 574,807. (No model.)

To @ZZ whom it may concern:

Be itknown that I, PETER H. JAcoBUs, a citizen of the United States, residing at Millstadt, in the county of St. Clair and State of Illinois, have invented certain new and useful Improvements in Car-Movers, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part hereof.

My invention has relation to improvements in car-movers and it consists in the novel arrangement and combination of parts more fully set forth in the specification, and pointed out in the claims.

In the drawings, Figure lis a side elevation of a rail with my car-mover mounted thereon. Fig. 2 is a middle transverse section on the line :c se of Fig. 3. Fig. 3 is a middle longitudinal section on the line y y of Fig. 2, and Fig. 4E is a perspective detached view of the rail-gripping block carried by the movable block of the device.

The object of my invention is to construct a car-mover which will be simple, compact, contain a minimum number of parts, and one which will develop a maximum amount of efficiency, the parts being so arranged that slipping on the rail under all conditions is avoided.

In detail the device may be described as follows:

Referring to the drawings, l represents the saddle of the mover adapted to rest upon and partially embrace the top of the rail 2. The saddle is hollow and of a form substantially as that shown in the drawings, having triangular terminal walls rounded at the top and each provided along its inner `surface with a U-shaped depression or socket 3 for guiding and receiving the bifurcated block 4, inserted into the chamber of the saddle. The forks or bifurcations 5 of the block i are provided with4 suitable alining openings for the reception of the pin 6, which serves as a fulcrum for the moving-lever 7 whose short arm is suitably curved to bear well against the flan ge of the wheel 8 of the car to be moved. The terminal walls of the saddle are provided with openings 9 10, the larger opening 9 serving pin G.

In assembling the parts the bifurcated block 4 is inserted into the chamber of the saddle from the bottom of the saddle and shoved up vuntil the openings of the bifurcations thereof come into alinementwith the opening 9 of the saddle. Then the lever 7 is inserted from the top until the opening 1l thereof also comes into alinement,when the pin is pushed through the openings of the several parts. The opening l0 of the saddle serves to permit the operator to knock out the pin should occasion arise to take the device apart. The base or lower surface of the bifurcated block 4E is provided with a groove l2 for the recept-ion of the prismatic gripping-block 13. The latter is substantially a triangular prism, with one of its faces (viz., that -facing the rear of the saddie) concave, the object of this construction being to provide an inclined cutting edge, as it were, along that edge of the prismatic block which comes in contact with the rail. The prismatic block is first slipped or inserted into the groove made for its reception, when it is secured by a screw 14, countersunk into the base of the bifurcated block.

When the parts are assembled and the carmover placed upon the rail, the relative position of the several parts is that indicated best in Fig. 2, the bifurcated block being forced to the base of the U-shaped depressions of the saddle, within which it is guided, the pin 6 thus occupyinga position whence it cannot possibly drop out through the opening 9 and where the parts cannot possibly be displaced. As power is applied and the long lever-arm 7 of the lever is depressed it is apparent that the resistance which the car offers to the short arm causes the cutting edge of the prismatio block to cut into and grip the surface of the rail, and thus prevent any slipping of the device along the rail and away from the carwheel. It is also obvious that the cutting edge of the prismatic block, 4being formed by the concavity of one of the faces, is such that it will prevent the slipping of the device along the rail away from the car, but readily permits the device to be moved toward the car and in close proximity to the wheel, the gripping or biting of the rail taking place only when the device is moved toward the cutting edge. It is on the same principle as passing a plane over a wood surface on which IOO the plane moves freely in one direction, but cuts or shaves the wood if passed in the opposite direction.

Having described my invention, what I claim isl. In a car-mover, a suitable saddle adapted to rest on the rail, a movable block mounted within said saddle, a lever pivoted to said movable block, and a second block carried at the base of the movable block and adapted to grip the rail upon the forcing of the lever against the wheel of the car to be moved, substantially as set forth.

2. In a car-mover, a suitable saddle, a bif urcated block mounted in and guided within the saddle, a lever adapted to be mounted between the bifurcations of the movable block, alining openings formed in the saddle, and the bifurcated block and the lever for the reception of a suitable pin or fulcrum for the lever, and a prismatic block having a concave face and thus forming an inclined cutting edge adapted to grip or bite the rail upon the forcing of the lever against the Wheel of the car to be moved, substantially as set forth.

3. In a ear-mover, a suitable saddle, a bifurcated block located and guided within the same, a lever pivotally mounted between the bifurcations, a groove at the base of the bifurcated block, a triangular prismatic block having a concave face and forming a rearwardly-inclined cutting edge adapted to grip or bite the rail upon the forcing of the lever against the Wheel of the car to be moved, but sliding freely along the rail when moved toward the car or away from the cutting edge thus formed, substantially as set forth.

4f. In a car-mover, a suitable saddle adapted to rest on the rail, a movable block mounted within the saddle, a lever pivoted to said movable block, and a second block carried at the base of the movable block, said second block having a concave face whereby an inclined cutting edge is formed for gripping or biting the rail upon the forcing of the lever against the wheel of the car to be moved, substantially as set forth.

In testimony whereof I affix my signature in presence of two witnesses.
