CAR-REPLACER.

SPECIFICATION forming part of Letters Patent N o. 762,176, dated June '7, 1904.

Application filed March l, 1904.

To all whom it may] concern,.-

Be it known that I, PHILo C..LocxwooD, a citizen of the United States, residing at Greenville, in the county of Mercer and State of Pennsylvania, have invented new and useful ment of parts hereinafter described, and particularly pointed out in the claims Jfollowing the description, reference being had to the accompanying drawings, forming a part of this specification, wherein-- Figure l is a top plan view of my improved car-replacer. Fig. 2 is a section taken on the line 2 2 of Fig. l. Fig. 3 is a detail perspective view of one of the inner frogs, and Fig. 4 is a similar view of one of the outer frogs.

Referring to the drawings, the numeral 1 indicates the main-track rails of a railway, which, as usual, are spiked to the ties 2. Spiked to the ties on the outer sides of the track-rails l are frogs 3, consisting of an inclined portion 4, which risesfrom approximately the level of the tie to the level of-the adjacent track-rail, and each of said frogs is provided on its outer edge with a forwardlyprojecting iiange 5, which projects above the inclined portion 4 of the frog and for a portion of its length is arranged at an angle to the track-rail 1, and what may be called the forward portion is arranged parallel with said track-rail. Abutting what may be called the rear end of the frog is a replacing-rail 7, which consists ofan ordinary railway-rail, which is spiked to the ties in the usual manner.

Disposed upon the inner sides of the trackrails l are frogs 8, which are substantially wedge-shaped and are inclined from their rear edges upwardly-thatis to say, their rear ends lie approximately liush with the ties to which they are spiked and gradually increase in thickness as the frog approaches the apex, at

Serial No. 195,979. (No model.)

which point it is practically flush with the top of the track-rail. As the frog approaches its apex it gradually narrows, and it is provided on its inner side with an elevated flange 9. Each of said frogs is provided with a rearward extension 10, the said extensions converging and meeting, as at 1l. The extended flange portions of the frogs 8 are inwardly beveled, as at 12, and at their extreme forward ends are disposed parallel to the track-rails l, as shown at 13. Formed on the outer edges of the frogs 8 are grooves 14, the purpose of which will presently be made apparent.

The operation of my improved device is as follows: Should the trucks become derailed as they approach the point at which the device is located, the car-wheels upon one side of the trucks will pass between the track-rails 1 and the adjacent guard-rail 7 and will be directed up upon the inclined ends of the inner frogs, and as the wheels ride up upon the highest points of the frogs they will be gradually guided toward the track-rails, and by the time that the foremost wheels have reached the foremost ends of the inner frogs the wheels will have been caused to move over upon the track-rails and the fianges of the wheels will drop into the grooves 14, whereby the wheels -will be gradually replaced upon the rails of the main track.

The same operation will occur should the car be derailed over to the right or to the left, and not only do the guard-rails 7 serve to guide the rails back to their correct course, but the extensions 12 of the inner frogs will also operate to produce the same effect should the wheels come in contact therewith.

It will be noted' that the outer frogs extend beyond the ends of the inner frogs, and thus constitute an important feature of the invention, as the extended portions of the outer frogs Operate to maintain the wheels on the rails of the main track until they have become securely replaced. It will also be noted that the flanges of the outermost frogs 3 are cxtended above the level of the track rails, whereby the wheels are prevented from lateral displacement as they ride into place onto the main track.

In practice the frogs are spiked to the ties IOO in the usual manner, and in addition thereto the forward ends of the outer frogs 3 are connected to the track-rails by bolts 15, which are passed through suitable apertures formed in the forward ends of the outer frogs and through the webs of the track-rails.

In practice the frogs are preferably made of pressed steel in order that they may be light, so as to be readily handled. It will be noticed that the frog-strip will iit or match the main-track rails in such manner that no interference whatever to said track-rails will occur to obstruct ordinary traflic.

Having described my invention, what I claim isfl. In a car-replacing device for railways,the combination with the track-rails, of inclined frogs arranged upon the opposite sides of each track-rail, said frogs being inclined from the ties up to the level of the track-rails, and guides for guiding the car-wheels onto the said inclined frogs, substantially as described.

2. The combination with the main track of a railway, of inclined frogs arranged upon the outer sides of the main tracks and provided with upwardly -projecting flanges, and inelined frogs arranged upon the inner sides of the rails adjacent to the first-mentioned frogs and provided upon their inner sides with inclined iianges,4 for the purpose specified.

3. In a car-replacingd`evice,the combination with the main-track rails., of inclined tapered frogs arranged on the outer sides of the maintrack rails and each provided with vertical tapered flanges, of frogs arranged upon the inner sides of the rails, said inner frogs being inclined substantially from the ties to the Y tread of the rails, substantially as described.

4. Inaear-replacing device,the combination with the main-track rails, of frogs arranged upon the outer sides thereof and each being inclined from the tie to a point substantially flush with the tread of the rails, each of said frogs being provided upon its outer edge with a forwardly-projecting flange, and rails attached to the ties and forming divergent eX- tensions of said iianges, substantially as described.

5. In a car-replacingdevi ce, the combination with the main-track rails, of frogs attached to the ties on the outer side of the rails, said frogs being inclined from the ties to a point sub stantially flush with the rails, and an inner V-shaped frog attached to the ties between the traclrails and provided with inclined faces for guiding the wheels onto the trackrails, substantially as described.

6. In adevice of the character described, the combination with the main-track rails, of divergent inclined frogs attached to the ties on the outer sides of said rails, and a V-shaped frog attached to the ties intermediate the rails, the ends of said outer frogs extending beyond the ends of the intermediate V-shaped frogs, substantially as and for the purpose specified.

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