RAI LWAY-SliNITCH FROG. M

SPECIFICATION forming part of Letters ratent No. 529,983, dated November 27, 1894.

Application filed July 2, 1894-; Serial No. 516,367, (No model.)

To all whom it may concern;

Be it known that I, BUssnL T. WALDREP, a citizen of the United States, residing at Tifton, in the county of 'Berrien and State of Georgia, have invented certain new and useful Improvements in Railway-Switch Frogs; and I do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in railway switch-frogs and it consists in certain novel features hereinafter described and claimed. 7

Reference is had to the accompanying drawings, wherein the same parts are indicated by the same letters throughout the several views.

Figure 1 represents a plan view of a portion of the track and siding, the switch being set for the main line. Fig. 2 represents a section along the line 1 y of Fig. 1, and looking toward the top of the sheet. Fig. 3 represents a plan view of the improved switchfrog in which the switch is set for the siding.

Fig. at represents a section along the line a: w of Fig. 3, and looking tothe left. Fig. 5 represents an inverted perspective view of the movable rail, and Fig 6 represents a perspective'view of the chair plate as detached from the rail. r A and A represent the rails of the main B and B represent the rails of the siding,

the rail B, being connected to the con tinuation B thereof, by means of the short rail B chair plate 0, and the movable rail D. The rails B and B are mounted at an incline on the blocks 6, as shown in Fig. 2, while the upper end of the rail B rests on the block b to which the frog-rail D is pivotally attached. The short rail B is connected to the rail B in the usual way, and has its opposite end tapering as shown, the web of the said tapering end engaging in the groove 0, beneath the overhanging lip c, and the vertical face 0 of the chair plate 0, the cut away edge of the rail fitting snugly against the edge of this vertical wall 0, as shown most clearly in Fig. 1.

The inside of the chair plate is curved as at o and c to fit snugly against the side of the main line rail A. The outside of the chair plate is provided with a flange or rib 0, having bolt holes 0 for securing the 7,

as at (1 near the free end of the frog rail,

and is finally curved outward as at (1 so as to avoid the possibility of being an obstruction when set for the main line. The said frog rail is in the form of a rail near its pivoted end, which is cut away in an inclined direction as shown at d in Fig. 5, which inclined portion fits snugly against the rail A when the switch is set for the siding. The free end of the frog rail is broad and flat as shown at Fig. 5, and is provided with a lug d to which the end f of the rod F is pivotally connected. The frog rail is also provided with lugs 01 and 01 which slide along the tops of the blocks E and E, and which rest on the said blocks when the device is set for the siding. The inner end of the frog railrests on the blocks 1) and E all of which blocks are firmly secured to the tops of the ties. The block E is cut away as at e to allow the flanges of the car wheels to pass when the switch is set for the main line.

The rod F is operated by the crank h on the shaft H, which shaft is revolved by a connection with any suitable switch stand or other apparatus designed for the purpose.

It will be noticed that when the switch is set for the main line as shown in Fig. 1, the main line is not broken, and hence with the herein described frog, there is no necessity for breaking the main line.

When the switch is set for the siding, as shown in Figs. 3 and 4, the frog rail D rests on top of the main rail A and is also supported by the blocks E, E, E and I), while the edge d is bracedagainst the rail B and the edge (1 is braced against the rail A.

Moreover, the novel construction of the chair plate 0 gives a firm support to the tapered end of the rails B Thus it will be seen that the herein described device afiords adequate protection and support to those parts of the frog rail and the siding rail that are generally broken or injured in frogs of somewhat similar construction. Theseand various other advantages of the herein described construction will be readily understood by anyone skilled in the art.

Having thus described my invention, what I claim, and desire to secure by Letters Patent of the United States, is-

In an apparatus of the character described, the combination with one of the main line rails and the blocks E and E of a pivoted frog rail adapted to swing partly over said main line rail, and provided with a straight edge (1 sloping outward as at d, curved outward as at d and provided with fiat lugs 61 and (1 adapted to rest on said blocks and give an enlarged supporting surface; a siding rail cut away at an angle and projecting above the level of said main line as; and adapted to bear against said sloping edged of the frog rail; and a chair plate C approximately triangular in form having the projection c fitting snugly against the web of the main line rail, with a groove. 0 dovetailed at c adaptedto receive the flange of the cut away siding rail; a vertical face 0 adapted to support the cut away side of the siding rail, and a flange 0 with belt holes 0 therein for securing said chair plate to the cross ties, substantially as and for the purposesdescribed.

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