DOUBLE-INCLlNE WRECKlNG-FROG.

SPECIFICATION forming part of Letters Patent No. 507,829, dated October 31,1893.

Application filed Tune 15, 1893.

To all whom it may concern:

Be it known that I, PATRICK T. MooNEY, a citizen of the United States, residing at Walnut Springs, in the county of Bosque and State of Texas, have invented new and useful Improvements in Double-Incline Wrecking- Frogs, of which the followingis aspeciflcation.

My invention relates to wrecking-frogs, and has for its object to provide such a device which shall possess -a minimum of weight and maximum of strength and durability, which will accurately guide a derailed wheel to replacement upon the track and which is also equally adapted to derailing a train, car or other vehicle when an occasion arises rendering derailment necessary or expedient.

To these ends my said invention con-sists in the novel construction and combination of parts hereinafter described and claimed, reference being made to the accompanying drawings, in which- Figure 1, is a perspective` view of my improved wrecking-frog. Fig. 2, is a cross-section of the same. Fig. 3, is a plan view of a railway -track with my invention applied thereto in position for use in replacing a train upon the rails of the track, and Fig. 4, is a similar view, my invention being shown as applied in position to derail a train.

In the said drawings the reference numeral l, represents the body or base of my improved wrecking-frog which is constructed of wood.

The body or base is substantially `triangular in configuration, as shown, its upper surface being formed with curved or convex doubleincline 2, and at the lower edge of its inner face it is cut away, as at 3, in order that it may fit over the bottom flange 4, of a railwayrail 5, and the inner face thereof abut or rest against the vertical side of the rail, as clearly illustrated in Figs. 3 and 4t, of the drawings. Midway between the ends of the body or base 1, at the apex or highest point thereof a metallic strip 6 is set into and secured in a transseriai No. 477,729. (No man.)

rail which is mounted upon and secured to the upper-double-incline surface of the body or base l, in any suitable manner, as shown, by rivets or nails, as shown. The free ends or extremities of this guide-rail 7a, extend beyond the ends of the body or base and are pointed and turned downwardly, as at 8,A to form teeth, which are adapted to be forced into the ties or earth along side the rail 5, and thus serve to steady the frogs while in use. Said rail 7 a, is inclined from its ends or extremities 8, upwardly to its middle-portion or apex 9, so as to conform accurately to the contour of the upper surface of thebody or base l, and its form in plan, as shown in the drawings, is angular. The guide-rail is disposed and secured upon the body or base, with its free ends 8 in line, or substantially in line, with the outer face of the body or base and its middle portion or apex 9 projecting slightly beyond the inner face of said body, or base so as to lap over the railway-rail 5, and is secured by a nail or rivet, or in other suitable manner, to the metallic strip 6, as shown in the drawings, the projecting part 9 of the said rail lying when in use, directly over the tread of a railway-rail 5, as best seen in Figs. Sand 4. By extending the apex of the rail 7, beyond the body or base l, the wheel of the vehicle or car to be replaced is accurately guided to a correct position, directly over the tread of the railway-railso that when it passes off the guide-rail 7 a, the tread of the wheel will drop onto the railway-rail 5, in proper position and without fail.' The apex 9 of the guide-railv is supported by the end of the strip 6, which passes directly beneath said apex and rests upon the railway rail.

In the practical employment of my improved double incline wrecking-frog provided with a raised or superimposed metallic guide-rail, it is possible to construct the body or base of the same of wood, the metallic guide-rail forming a trackway upon which the tread of the car or other vehicle wheel travels while being derailed from or replaced IOO never been provided with a raised guide-rail upon which the tread of the wheel to be replaced is guided and travels, and hence it has been essential to construct such prior devices entirely of metal, since if it were constructed of wood, the fiange of the wheel to be replaced would cut into and split the device, thus destroying it. In my invention, however, it is possible to construct the body of the device of wood, since the raised metallic rail receives the tread of the wheel, the iiange thereof running along and being guided by the inner side of said guide-rail, but not coming in contact with the wooden body or base of the device.

I thus provide a wrecking-frog which is exceedingly light of weight as compared with devices of the prior art and which may be manufactured at a greatly reduced cost, while possessing all the requisite strength and durability by reason of the provision of the metallic gnide-rail which sustains in itself the wear incident to use.

My improved double-incline wrecking-frog is adapted for use as a replacer and a derailer.

In Fig. 3, I have shown the device applied to a railway-rail in position to replace upon said rail a car or vehicle which has, through necessityor accident been displaced. In this instance, it will be noticed that the frog is placed outside one rail of a doublerail track and the guide-rail 7a, leads up to and over the railwayrail 5, so that the tread of the wheel to be replaced will travel up said guide-rail, being guided thereon by the flange of the wheel running along the side of the guide-rail until the apex 9, thereof, is reached, at which time the wheel is directly over the railway-rail 5, and from which point it runs easily off the guide-rail 7 a, onto the railwayrail.

In Fig. 1, the frog is illustrated as arranged in proper position with relation to a railwayrail to act as a derailer, and it will be seen that in this figure it isarranged at the inside of one rail of a double-rail track. The vehicle or car to be derailed, traveling on the railwayrail 5, comes in contact with the edge of the guide-rail rlaat orabout the apeXtl1ereof,which projects slightly beyond the bodyorbase, 1, of the device, so as to lap over the railway-rail, and is guided olf said railway-rail, thus derailing the car or vehicle. As far as I am aware,

there has never heretofore been constructed a device which will perform both the oiiice of a car or vehicle replacer and a derailer. I consider this feature of my invention of much importance, because in some cases, and especially when a train is wrecked without derailment, the cargo upon one or more of the cars often catches fire and then it is essential to derail the car or cars which are burning in order to protect the rest of the train. This is readily accomplished, as herein described, by the use of my improved frog.

In the practice of my invention, I intend to employ, as auxiliary to my improved frog, one of the ordinary inclines which is comprised in the implements carried by every train-crew, one of which is shown in Fig. 3 of the accompanying drawings. This incline will serve merely as a support upon which the wheel, opposite that on which my improved frog acts, may travel.

Having thus described my invention, what I claim is- 1. A wrecking'frog consisting of a body, or base, of wood, having its upper surface conveX from end to end, a metallic, angularguiderail secured upon and rising above said con- Vex surface, said guide-rail converging toward the railway-rail from its ends toward its apex which projects beyond the inner,vertical face of the base and overlies the tread of the rail, the convex surface of the said base being cut away along the inner edge of the guide rail to permit the passage of the flange of the wheel and throw the weight upon the guide rail,and a metallicstripsettransversely into the base, its end which passes beneath the apex of the angular guide-rail and supports the same being formed into a hook to engage the railway rail, substantially as described.

2. A wrecking frog consisting of a Wooden body, or base, having its upper surface convex from end to end, an angular, metallic guide-rail. secured upon and rising from the said convex surface, its apex' projecting beyond the vertical, inner face of the body or base of the frog and overlying the tread of the rail way-rail, and a transverse metallic strip set into the base and passing beneath the apex of the guide-rail to support the same and to hook over the railway-rail, the free ends of said guide -rail being extended beyond the Wooden-base and turned downward to form teeth adapted to engage the sleepers, substantially as described.

In testimony whereof I have hereunto set my hand in presence of two subscribing Witnesses.
