RERAILING-FROG.

Specification of Letters Patent.

Patented Nov. '7, 1911.

Application filed February 14, 1911. Serial No. 608,564.

To all whom it may concern:

Be it known that I, JOHN L. NICOLAI, a citizen of the United States, residing at Alliance, in the county of Boxbutte and State of Nebraska, have invented certain new and useful Improvements in Rerailing- Frogs; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

My invention relates to a rel-ailing frog and. has for its object to provide a device for assisting the wheels of a railway or like car back onto the rails from the level of the road bed.

My device comprises more particularly a pair of frogs, one for use on the outside rail and one on the inside rail, which are slightly different in construction in order to adapt them for use with the car wheels having oppositely disposed flanges.

It is a further object of my invention to provide the improved details of structure hereinafter described and illustrated in the accompanying drawings, wherein Figure I is a perspective view of a railway track having rails equipped with my improved frogs. Fig. II is an enlarged plan view of the outside frog member. Fig. III is an end view of the same. Fig. IV is a plan view of the inside frog member. Fig. V is an end view of the same. Fig, VI'1s a vertical section on the line VIVI, Fig. II, showing the adjustable supporting blocks.

Referring more in detail to the parts 1 designates railway rails which are set on ordinary ties 2 and adapted for carrying the flanged wheels 3, these parts being of the usual and well known construction.

41 designates the outside frog member which is preferably constructed of wrought iron and has inclined track-ways 5 terminating in a central horizontal section 6. At the inside of the track-ways are guard sec tions 7 which, when the apparatus is in place, extend up along the side of the rail and are turned laterally to provide a horizontal hanger member 8, that is adapted to extend over the top of the ball of the rail and has a depending flange 9 that hangs on the inside of the rail and retains the frog in place. With the outside frog the horizontal track section 6 is in the same plane with the hanger member 8, so that the flange of a wheel running up the track-way may pass onto the horizontal section and thence over the hanger member to reach its position at the inside of the rail without interruption. The track ways are preferably flaring toward their lower ends and have upturned flanges 10 at their outside edges, which are inclined upwardly and outwardly therefrom. Formed integrally with the frog, at the outer side thereof, are lugs 11 having apertures for receiving the spikes 12, by which the frog may be secured to the cross ties. In order to accommodate the vfrog to rails of different heights, I prefer to make thesame adjustable by providing its under surface with stepped shoulders 13 and using blocks 14 having stepped shoulders 15 for taking into the frog shoulders and for supporting the frog. In order to anchor the parts together, I provide the blocks with sockets 16 and the frog with apertures 17, so that a pin 18 may be dropped through the apertures into the sockets and hold the parts together without interfering with the travel of the wheels on the frog. It is apparent that with this construction the block may he stepped inwardly or outwardly relative to the inclined track ways to provide vertical adjustment for the frog.

While I have been describing the con struction of the outside frog, this description answers equally well for the inside member with the exception that the plane 6, between the track-ways 5 of the inside frog, is set down from the horizontal hanger parts 8 a distance equal to the width of the wheel flange, so that when the wheel runs up the trackway to be replaced on the rail,'the flange will engage the side face 8 of the hanger part and be turned onto the rail.

In order to obviate misplacement of the frogs by the engagement of the wheels therewith, I prefer to bevel the ends of the sides 7 and hanger parts 8, as illustrated, so that should the wheel or flange lie close to the rail, it will be moved over onto the trackway when it engages the frog and thereby obviate Inisplacement of the frog.

In using the frogs to replace a car that has run off of the track, they are hung on the same side of the rails. The car is then moved forwardly so that the flanges engage the inclined track-ways of the frogs and are carried up on the track-ways until the flange of the outside wheel moves over its hanger and drops inside of the rail; the inside wheel moving up its track-way until the wheel flange engages the partof the hanger depending over the inside of the rail ball and is turned thereby, so that it will travel directly overv the rail.

' With a low rail, the adjusting blocks may be set back under the inclined track-ways, so that the top of the frog will be at the proper height for a low rail. With a high rail the blocks may be moved outwardly so that the frog is elevated.

Having thus described my invention, what I claim as new therein and desire to secure by Letters-Patent is 1. A rerailing frog comprising vertically adjustable inclined trackways having a plane part therebetween, a hanger part for supporting the frog on a rail, and an upturned flange on the outside edges of the track-ways and plane part.

2. A rerailing frog comprising vertically adjustable inclined track-ways having a plane part therebetween and having guard sections at its inner edges, a hanger integral with the guard sections and plane part and provided with a keeper flange, and a flange at the outer edges of the track-ways, substantially as set forth.

3. A rerailing frog comprising vertically adjustable inclined track-ways, and a hanger, said track-ways being oppositely disposed and terminating in a part in the plane of the hanger, and an upturned flange on the outer edge of the track-ways, for the purpose set forth.

4:. A rerailing frog comprising vertically adjustable inclined track-ways and a hanger, said traok-ways being oppositely disposed and terminating in a part in the plane of the hanger, and outwardly inclined upturned flanges on the outer edge of the track-ways, for the purpose set forth.

5. A rerailing frog comprising vertically adjustable inclined track-ways, a hanger connected with the track-ways, and means for supporting the track-ways at variable heights, for the purpose set forth.

6. A rerailing frog comprising inclined track-ways, a hanger connected with the track-ways, said track-ways having stepped shoulders on their under surfaces, blocks having stepped shoulders adapted for adjustable cooperation with the shoulders on the track-ways, and means for anchoring the blocks to the track-ways.

7. A rerailing frog comprising vertically adjustable inclined track-ways, a hanger connected with the track-ways, upturned flanges on the outer edges of the track-ways, and lugs on the outer side of the frog having apertures whereby the frog may be secured to cross ties, substantially as and for the purpose set forth.

8. A rerailing frog comprising vertically adjustable inclined track-ways, a hanger connected with the track-ways and adapted to extend over the ball of a rail, the ends of the hanger being beveled, substantially as set forth.

9. Rerailing frogs arranged in pairs, both members comprising hangers and having vertically adjustable inclined track-ways disposed toward a center, the track-ways in the outer member terminating in the plane of the hanger, and the track-ways of the inner member terminating below the plane of the hanger, substantially as and .for the purpose set forth.

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

JOHN L. NICOLAI.
