Y i SPECIFCATION forming part of Letters Patent N o. 684,344, dated October 8, 1901.

Application filed October 29,1900. `Serial. No'. 34,77i3. (Remodel.)

To all whom, it may omwemj Beit known that we, JAMES BIRDWELL and W'ILLIAM O. VANCE, citizens of the United States, residing at New Albany, in the county of Floyd and State of Indiana, have invented a new and useful Car-Replacer, of which the following is a specification.

Our present invention relates to a novel car-replacer, the object in view being to produce a simple and inexpensive car-replacing device or wrecking apparatus designed to effeet the replacement of the derailed car upon the rails.

A further object of the invention is to provide as adjuncts for the Wrecking-frogs peculiarly-constructed approach-blocks having iiexible connection with the frogs and designed to be placed at various angles for the purpose of facilitating the approach tothe frogs of cars whose wheels are located at considerable distances from the tracks.

To the accomplishment of these objects the invention .consists in the construction and arrangement of parts to be hereinafter described, illustrated in the accompanying drawings, and defined in the appended claims.

In said drawings, Figure l is a top plan view of a section of railway-track, showing our replacing devices applied as in use, the adjusted positions of the approaches being indicated by dotted lines. Fig. 2 is a detail view, on a somewhat-enlarged scale, of the outer wreckingfrog. Fig. 3 is a central transverse section therethrough. Fig. 4 is a similar View of one of the approach-blocks. Fig. 5 isa detail view of the inner frog. Fig. Gis a View similar to Fig. l, but showing slightly-modified forms of frogs; and Figs. 7 and 8 are detail views of modified outer and inner frogs.

Referring to the numerals of reference employed to designate corresponding parts in the several views, l and 2 indicate a pair of rails comprising a section of railway-track.

3 and 4 indicate the outer and inner wrecking-frogs, and 5, 6, '7, and 8 the approachblocks. In use the frogs and approach-blocks are arranged in sets-that is to say, each of the frogs is provided at each end with an approach-block iiexibly connected thereto-as,

for instance, by hooks 9, carried by the appreach-blocks at the side thereof opposite the adjacent track and designed for engagement with staples 10 or other suitable keepers projecting from the frogs. As shown in Fig. l of the drawings, one set of devices, comprehending a frog and two of the approach-blocks, is located adjacent to the inner side of one rail, and the other set is located adjacent to the outer side or face of the other rail, this relation of the replacing devices to the rails being obviously necessary, as the Wheels at the opposite sides of a derailed car will be located, respectively, between the rails and beyond the outer side of one of them.

Each of the wrecking-frogs 3 and 4 is a solid block of forged steel of generally oblong form and of a height suiicient to bring the upper face 11 of said frog flush with the upper surface of the track when the frog is positioned upon the ties. For the purpose of facilitating the travel of the car-wheels to the upper surface of the frog the opposite ends of the latter are provided with Haring recesses which define inclined approach-faces 12 and vertical rail-anges 13. At the center of the frog the iianges 13 are cut away and intermediate of them is located a replacingnose 14, constituting a continuation of the inclined approach-faces l2 and having one longitudinal edge 15 curved, as shown. The center of the nose of the outer frog 3 is 1ocated in the vertical plane of the track side of the frog and in ahorizontal plane somewhat above the upper surface of the frog. This peculiarity of form of the nose 14 is designed with a view to causing the elevation of the wheel suiciently .above the track to permit the wheel-flange to pass over the track for location at the opposite side thereof.

The construction of the inner frog 4 is somewhat different from that of the outer frog, for the reason that the latter is designed to lift the wheel-ange over the track, while the former is intended to draw the car laterally for the purpose of presenting the flanges of the inside wheels against the side of the rail, it being obvious that since the Wheel- IOC flanges are located at the inside of the wheels f there is no necessity for lifting the flange of the wheel passing up the inside frog, eirceptv so far as may be necessary to bring the tread of the wheel in the horizontal plane 'of the upper face of the track. The nose let'of the frog 4 is therefore not elevated above the upper surface of the frog, but, on the contrary, is slightly depressed, and its center instead of being located in the plane of the track side of the frog is extended slightly beyond the face of the frog adjacent to the track, as indicated at 14, and the face of the frog is vertically inclined, as shown, for the purpose of presenting su fticient space between the upper portion of the frog and the track to permit the proper manipulation of a pair of switch-points 14". The switch-points 14h constitute,in eifect,pivoted sections or extensions of the flanges 13, being pivoted at their outer ends adjacent to the inner ends of the rail-fianges 13, as indicated at 14C, and having their tapering ends or points disposed normally against the face of the nose 14. It will be noted,further,that the approach-faces 12 of both the inner and outer frogs have an upward inclination from the ends of the frog to the nose 14 and that they have a transverse inclination tending to cause the carwheels to gravitate toward the track as they are advanced toward the nose, the railflanges 13 serving as guards to prevent the wheels from abutting against the rails before they are drawn up the inelines of the nose of the outer frog for elevation above the track or against the front faces of the inner frog to be drawn toward the track.

The approach- blocks 5, 6, 7, and 8 are all identically constructed, and a description of one will therefore serve to give aclear understanding of the construction of the others. Each block is of substantially oblong form, as shown, but is preferably somewhat widened at its outer end to give the blocks a greater range of use without adjustment. The upper face of each block is inclined, as shown, from its outer end to the inner end thereof, which latter is located in substantially the horizontal plane of the outer end of the adjacent approach-face 12 ofthe frog. For the purpose of preventing accidental displacement of the wheels from the blocks the latter are provided at their opposite sides with vertical longitudinal guard-iianges 16, and the upper face of the block is preferably corrugated longitudinally, as indicated at 17, to define lon gitudinally-dispos'ed and somewhat oblique lead-grooves to cause the wheel as it is drawn over the face of the block to move toward the rail. It will now be seen that as thel derailed car is drawn forward its wheels will be presented to the lower outer ends of the approach-blocks and will be drawn up the inclined surfaces of the blocks until they are deposited upon the inclined approachfaces 12 of the frogs. Continued movement of the car will cause the wheels to travel up the faces 12 and to move toward the railflanges 13, finally coming in contact with the esas/i4 replacing-noses 1i, which will guide the wheels to positions above the tracks to effect the replacement of the car. As premised,

however, the manner in which the two frogs 'Y guide the car-wheels is somewhat different,

as the wheels traversing the outside frog will ride upon the nose thereof until their flanges are passed over the adjacent track, while those wheels traversing the inside frog will present their flanges between the front face of the frog and the adjacent switch-point, the

curvature of thefrog serving .to urge the wheel laterally, which swings the switchy point against the inner side face of the track,

as stated. It Will be seen that as the wheelange passes beyond the end of the switchpoint which has guided it to place it will be permitted to continue its movement withoutV manner in which the approach-blocks maybe Y Y swung around at an angle to the rails whenY the wheels of the derailed car are located at considerable distances from the tracks. If desired, the under faces of the frogs and approach-blocks maybe provided with depending pins designed to aid in the fixed retention of the replacing devices; but such retaining means may or may not be employed, in accord-ance with the individual ideas of the manufacturer. The frogs may also `be 7SY scf' Yme;

provided with track-engaging hooks 18', as

shown.

In Figs. 6, 7, and S we have illustrated our wrecking apparatus in a slightly-modified form. of being provided with a fixed nose issurmounted by a centrally-pivoted switch-nose` 14d, located between the inner ends of ther In this form the outer frog 3 instead flanges 13 and designed to be shifted for the 1 purpose of bringing either end into close conf tact with the rail, according to the direction H521V of movement of the car being replaced. This switch-nose is retained in its shifted position by a reversible locking-block 14e, designed.V to lit snugly within either end of a recess laf,VY

immediately behind the switch-nose. The locking-block is of angular form, as shown, and is designed to be placed loosely in either end of the recess for the purpose of retain'- ing thenose in either of its adjusted posi- Y tions. last three figures is identical with the corre-V sponding frog illustrated in the precedingY figures, except that the face `adjacent to the Y.

track is not vertically inclined and the nose 14g does not extendY to the track side of the Y i l block, but is removed therefrom in order that The inner frog at illustrated in these f the switch-points maybe normally moved toA Y the frog adjacent to the track. The modeof use of this modified form of the apparatus is .a point within the plane of the side face of j precisely the same as that described in connection with the preferred form and need not, therefore, be reiterated.

From the foregoing it will be observed that We have produced a simple, durable, inexpensive, and efficient car-replacing device adapted to accomplish the several objects hereinbefore enumerated; but While the present embodiment of the invention appears at this time to be preferable We Wish to reserve the right to effect such changes, modifications, and variations as may be comprehendcd Within the scope of the protection prayed.
