HARVEY C. BEIGE AND \VILLIAM C. SMITH, OF LA CROSSE, VISCONSIN.

RAILWAY=FROG.

SPECIFICATION forming part of Letters Patent No. 394,754, dated December 18, 1888.

Application filed September 19, 1888. Serial No. 285,769. (No model.)

T0 a/ZZ whom it may concern.-

Be it known that we, HARVEY 'iRIC-E and \VILLIAM C. SMITH, citizens of the United States, residing at La Crosse, in the county of La Crosse and State of \Yisconsin, have invented certain new and useful Improvements in Railway-Frogs; and we do hereby declare the following to be a full, clear, and exact de scription of the invention, such as will enable others skilled in the art to which itappertains to make and use the same.

Our invention relates to improvements in railway-frogs; and the object of our invention is to provide a means of makinga contiiuious rail with the frog-point by hinging the same in a novel manner, and in locating and operating the frog-point upon a novelly-constructed bed-plate. \Vo attain this objectby a certain combination and arrangement of parts, which will be fully described in this specification, and illustrated in. the accompa-.

nying drawings, in which Figure 1 is a perspective view of the frogpoint. Fig. 2 is a similar view of the bed-plate. Fig. 3 is an end view of the portion which constitutes a part of the hinge of the frogpoint. Fig. 4c is a view of one of the sheaves through which the operating-lever rod passes. Fig. 5 is a plan view of our invention completed and ready for use. Fig. (3 is a longitudinal sectional view on the line a: m, Fig. 5. Fig. 7 is a view of the operating lever or arm attached to the frog-point.

A designates the frog-point, which is constructed in the ordinary way, with the exception of the angular shoulders at and the semicircular reduced portions a, which form a tongue that is adapted to fit into the cavity a in one end of the piece C.

B represents the bed-plate, which is constructed with the angular shoulders I) and b, the projections b and the raised portions 19 Said plate is thicker at the end where the frog-point is hinged, for the purpose of being embedded in the cross-tie at this point and securely held in position. The projections 19 and the raised portions b are to keep the frogpoint A in position and prevent it from twisting or springing out of shape, owing to the lateral strains caused by the cars passing over it.

The plate B is spiked to the cross-ties, so that the angular shoulders I) and b will fit closely against the ends of the rails D D and E E. This holds said bed-plate securely, preventing it from slipping backward or forward. It will be observed that when the plate B is thus located the end b fits closely in between the ends of the rails E E.

The piece O is constructed, as shown in Fig. 3, with a view of being adapted to fit closely between the ends of the rails D D, where the piece is bolted by means of the bolts d. The caw'ity c is formed to receive the tongue formed upon the end of the frog-point by means of reducing the same upon both sides. It will readily be seen that the ends of the frog-point A and the piece C, being thus constructed, are adapted to each other, and when placed together they form a hinge, F, by means of which the frog-point A is operated. hinge is pivoted with the bolt f, which has its head countersunk in the end of piece 0. The hinge F being thus arranged and constructed, it cannot possibly get out of order or place. The piece 0 may be cast solid with the rails, so as to constitute a part thereof; but frequently we find it convenient to make it independently of them, as before described.

G is one of the sheaves,which are secured to the cross-ties in which the rod I-I works. The rod I is secured to the frog-point A by means of bolts. Said rod connects with the bellcrank leverJ, which is pivoted to the plate K on the cross-tie and bolted to the horizontal rod H. The rod H is attached to another bellcrank lever, L, at the switclnwhich is pivoted on another plate.

M represents the arm of the switch-stand, which transmits motion to the bell-crank lever L. This imparts motion to the horizontal rod H, thence to the right-angled lever J ,which operates the rod 1, that is attached to the frogpoint A, by means of which said frog-point can be easily thrown to either rail E E.

WVe do not wish to limit ourselves to the precise construction of' hinge described and shown, as we desire to include any construc- Said a tion involving our improved plate 1 and part (i.

It being apparent that our invention is practical and eil'eetual in operation, it is useless to further enlarge upon its merits.

\Vhat we claim is 1. In a frog-point for making a continuous rail, the combination of the bed-plate 13, the movable frog-point A, the piece 0,1;lxerails l) 1), whereby the hinge i1 is formed, and suitable means for operating said frog-point, sub stantially as described and shown.

The combination of the movable frog A, the main and. siding rails E E and D D, the portion 0,1oeated between the ends of the rails l) D, the bed-plate l3, and any suitable means for operating said lj'rog-point, substantially as (.leseribed, and for the purpose set forth.

3. The combination of the bed-plate 13, the frog-point A, o1j)erating upon said bed'plate, the piece C, located between the ends of the rails D D, the rails I) II) and E E, the lever or arm I, attaehed to the frog-point A, the lever J, pivoted on the plate K, the rod ll, secured to the lever L, the lever L, the plate K, the sheaves G, seeured to the (fl'OHS-HGS, and the arm of switoh-staml, substantially as described, and for the purpose set forth.

In testimony whereof we al'tix our signatures in presenee of two witnesses.
