EMIL W. ROSENBERG, OF CHICAGO, ILLINOIS.

CAR-REPLACER.

SPECIFICATION forming part of Letters Patent No. 750,896, dated February 2, 1904.

Application filed July 11, 1903. Serial No. 165,149. (No model.)

To all whom, it may concern:

Be it known that I, EMIL W. ROSEN'BERG, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Car-Replacers, of which'the following is a specification.

This invention relates to improvements in frogs for replacing derailed cars and engines on the rails; and its object is to simplify and improve the construction of replacer-frogs so that they can be manufactured at less expense than heretofore and used with more satisfactory results.

A further object of the invention is to provide frogs which are adapted for any size of rail and which can be used for replacing cars or engines in either direction and from either side of the rail.

IVith these and other ends in view the invention consists of the novel construction of the frogs illustrated in the accompanying drawings, in whichi Figure 1 is a perspective view illustrating the use of my invention and showing a pair of wheels in full lines about to mount the frogs and in broken lines sliding from the frogs to the rails. Figs. 2, 3, and 4 are perspective views of the frogs. Figs. 5 and 6 are cross-sectional views on the lines 5 5 and 6 6 of Fig. 2.

In the drawings like numerals of reference designate corresponding parts in the several figures, and referring thereto A is the frog which is adapted to be used on the outside of the rail, and B is the frog which is adapted to be used on the inside of the rail. These frogs are constructed substantially alike, except that A is higher at its high end than B to lift the flange of the wheel overl the rail.

Each frog is wedge-shaped-that is to say, is in the form of an acute-angled triangular prism both longitudinally and transversely, being higher at one end 10 and at one side 1l than at its other end 12 and side 13. The top 14 and bottom 15 are substantially fiat and are inclined toward each other longitudinally and transversely of the frog from the wide end 10 to the narrow end 12 and from the wide side 11 to the narrow side 13. The construction is such that when the frog is resting on one face 14: or 15 it will have an even and fiat bearing throughout the major portion of the face and at each corner of the narrow end thereof, and the upper face, which is to receive the wheel, is inclined toward the rail to cause the wheel to slide toward and onto the rail as it rides up to the high end.

For the purpose of firmly securing the frog in position I provide flanges 16, which are adapted to take into the ties, and in order that the position of the frog with relation to the rail may be constantly maintained I provide projecting lugs 17 on the narrow side of Vthe frog to rest upon the flange of the rail, so

that the rail will support the inner side of the frog should the ties sink under the weight of the car or engine.

These frogs are preferably made in the form of shells and suitably braced, and they are simple in construction, free from movable or comi plicated parts, and comparatively inexpensive to manufacture. Theycan be used to replace a car or engine in either direction of the track and from either side of the rails, and of course they can be. secured in position on the ties to replace the car or engine from any reasonable angle to the rails. For the purpose of enabling the wheels to mount the frogs more readily I prefer to cut out the faces of the narrow end of each frog at 18 between the corners, which provide a rm and substantial bearing for this end of the frog.

As these frogs can bevused reversibly, it is apparent that they need only be made of a length for use in replacing cars or engines in one direction, and the simplicity of construction enables the frogs to be made very strong without increasing their weight or adding to the expense of manufacture. The Wedge shape ofthe frogs enables the car or engine to mount them easily, and as the wheels move up to the wide end they will naturally slide down the inclined faces toward and onto the rails.

\ Without limiting myself to the exact construction and arrangement of parts herein shown and described, what I claim, and desire 4.
