Specification of Letters Patent.

Patented Dec. 9,1919.

Application filed August 3, 1918. Serial No. 248,157.

To all whom it may concern:

Be it known that I, FRANK C. WENTINK, a citizen of the United States, residing at Appleton, county of Outagamie, and State of Wisconsin, have invented new and useful Improvements in Car-Movers, of which the following is a specification.

My invention relates to improvements in that class of car movers for which Letters Patent of the United States, No. 1,252,354, were issued January 1st, 1918, and the same is explained by reference to the accompanying drawings, in which igure is a side view.

Fig. 2 is a bottom view, part in section, drawn on line 2-2 of Fig. 1.

Fig. 3 is a detail. 7 r Fig. 4 is a section, drawn on line H of Fig; 5 is a section, drawn on line 5-5 of Fig. 1.

Fig. 6 is a section, drawn on line 6-6 of Fig. 5, and

Fig. 7 is a bottom View of theshoe.

Like parts are identified bythe same reference numerals throughout the several views.

As heretofore constructed and shown in said patent, the lugs 1, 1 were formed as separate members and bolted to the shoe 2 in such a manner that the lugs performed the additional function of bearing against the ends of and holding the hard metal pinch blocks or dowels 3 in place, while by my present construction said hard metal blocks or dowels are socketed in the casting in such a manner that they may be securely held in place by the cotter pins 4, which pins are inserted through lugs 5, cast upon the shoe 2. The blocks or dowels 3 are adapted by a downward pressure upon the handle 6 to biteupon railway rails, and thus prevent the mover from slidin backwardly as it moves'the railway car orwardly, as the dowels 3 are rectangular or square in shape and the cast metal sockets which re- .ceive them progressively increase in depth from the sides of the shoe inwardly toward the central portion therof. These sockets are so formed that the cast metal will wholly embrace two sides of the dowels, and will lap over upon the other two sides sufficiently to prevent the dowels from falling out or from being withdrawn from the sockets 1n any manner, except by moving them longitudinally, and withdrawing them atthe respective sides of the shoe after the cotter pins have been removed.

Owing to the fact that the sockets progressively increase in depth toward the central portion of the shoeon the under side, the dowels may be almost wholly inclosed by the cast metal at their inner ends, one corner, however, projecting slightly, as shown, whereby the rail may be engaged along one edge of the dowel throughout its length.

The rail surfaces being hard and the shoe being moved. with a sliding motion along such surfaces in the intervals between car advancing operations, the projecting edges of the dowels are rapidly worn, and therefore it is important that the dowels be easily removable by making them square in cross section. Four rail biting edges or corners are provided, and are adapted to be used in succession, by removing the dowels when one edge becomes worn, and rotating them a quarter of a turn and re-inserting them. This necessity for frequent removals, re-adjustments and replacements makes it important to provide a form of construction inwhich simple, inexpensive and readily removable anchoring means may be employed, and therefore I regard the combination of the peculiarly arranged socket walls with the cotter pins as an exceedingly important feature of the invention herein claimed. The cotter pins can be easily withdrawn and other cotter pins substituted if damaged or destroyed by withdrawing them. The en tire operation of re-adjusting or replacing the dowels therefore requires very little time and effort, and substantially no expense, and the operation involves no separation of the working parts of the tool with consequent necessity for reassembly and readjustments as in the devices of this character heretofore used.

The construction above described also en ables me to form the lugs or ears 1 integrally with the shoe, and to also form the apertures or lugs 5 integrally as extensions of the concave rear portion of the shoe, whereby all parts of the shoe may be composed of a single casting. This also reduces the expense. In using the shoe, the thrust of the dowels is upwardly and inwardly toward the inner ends of the receiving sockets where the body of cast metal greatest. This is due to the fact that the dowels are inclined upwardly and inwardly and tend to push into the sockets and away from the cotter pins. Therefore, the cotter pins are subject to no strain since they are merely required to keep the dowels from falling out of the sockets by gravity when the'shoe is raised from the rail surface, or when it is being carried from place to place.

Having thus described. my invention what I claim as new, and desire to secure by Letters Patent, is

1. In a device of the described class, the combination with a shoe adapted to be moved along a railway track, of a pair oi rectangular blocks of harder metal than that in which they are embedded, and a pair of cotter pins adapted to bear against the protruding ends of said blocks, and cooperate with the surrounding cast metal in holding said blocks in place.

2. A shoe formed of cast iron provided with a pair of vertical lugs cast inte ral therewith, adapted to be pivotally attached to an operating lever, a second pair of lugs, also cast integral therewith for the reception of a pair of cotter pins, a pair of hard metal angular dowel blocks partially embedded in said cast metal, and a pair of cotter pins adapted to bear against the protruding ends of said dowel blocks, and co operate with the surrounding metal in holding said dowel blocks in place.

3. In a car moving device, the combination of a shoe adapted to be moved along a railway traclnsaid shoe provided with converging openings for the reception of hardened pinch blocks, and cotter pins bearing against the protruding ends of said pinch blocks to retain them in operative relation. 7

In testimony whereof I aflixniy signature in the presence of two witnesses. is
