Specification of Letters Patent.

Patented Aug. 2o, i912.

1912. seria1No. 690,773.

Application filed April 15,

wise provided with a corresponding dividing rib 10.

Thev frogs are adapted upon each rail as shown, tion that the base of the V containing the entrances La and 5a rests upon one of the cross .ties 11 from which it is inclined to the horizontal rising gradually to the level of the ball of the rail, the narrow forward portion of the frog being supported upon the legs 12.

The operation of the device will be obvious to one skilled in the art.

The two frog members are not counter parts one ofthe other but are rather coinplementary and they are arranged in such manner that the guard ribs 3 shall be within the rails and the guard ribs 2 without the same, in which position the merging point of the grooves in each case will be just within flange of the wheel guided from either d1- rection will drop to its proper position upon the inner side of the rail ball. Whether the wheels are derailed upon one side of the track or the other they will, when drawn forward, engage with the flaring entrances a and 5a and will be deflected by said grooves and directed by the

guard ribs

2 and 3 laterally to the proper position relative to the rails, when continued further movement will bring the wheels upon the rails in proper relation thereto.

Having thus described claim:

1. A rerailing frog comprising a truncated V-shaped casting inclined to the horizontal and having upon its upper face marginal guard ribs extending from the base upwardly toward the truncated end of the kV, and also provided substantially parallel to one of the ribs with a wheel iiange receiving groove and upon the opposite side at an oblique angle to the guard rib with a similar wheel fiange receiving groove merging into the rst groove at the apex, the twoflange receiving grooves merging at a point just inside the rail, the lower portions of the groove being widened laterally to afford a flaring entrance thereto, said casting being provided o-n its lower face along its axis with a rail receiving groove, and upon its upper face above the rail receiving groove with a corresponding axial dividing rib.

2. A rerailing frog comprising a truncated To all whom t may concern Be it known that I, CHARLES HILL GAM- BILL, a citizen of the United States, residing at Nashville, in the county of Davidson and Stat-e of Tennessee, have invented certain new and useful Improvements in Car- Rerailing Frogs, 'of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to rerailing frogs by means of which the wheels of railway cars and engines maybe expeditiously and accurately guided upon the rails when they have been derailed from any cause.

The object of the invention is the provision of a portable frog of this character which can be manufactured at a minimum of cost and will be durable and effective in its operation.

The invention as hereinafter particularly claimed will be readily understood from the accompanying drawings taken in connection with the detailed description of the same which follows:

In the drawings: Figure 1 is a top plan. view of a pair of frogs in operative relation to the rails; Fig. 2 is a side elevation of the same; Fig. 3 is a transverse vertical section on the line 3-3 of Fig. 1; and Fig. 4t is a similar section on the line 4--4 of Fig. 1

My improved rerailing frog comprises essentially a castingl having the form in top plan of a truncated V. The upper face of the .frog is slightly inclined to form an approach and is provided with

marginal guard ribs

2 and 3, which extend from the broad base of the V to the truncated apex of the same. The upper face of the frog is provided substantially parallel to the guard rib 3 with a flange receiving groove 4c and at an oblique angle to the guard rib 2 with a flange receiving groove 5. These two grooves converge toward the apex of the V and merge at the point 6, which lies at that side of the axis of the V which is between the rails 7 and 8 of the track. The lower portions of the

grooves

4 and 5 are widened laterally at 4a and 5a to afford a flaring entrance thereto, the entrance La when the frog is in operative position being between the rails and the entrance 5a exterior thereto.

The frog is provided upon its lower face with a rail receiving groove 9 which corresponds substantially with the axis of the frog, the upper face of the frog being liketo be placed one and in such posithe invention, l

the rails at the point where the V-shaped casting provided with an inclined said Wheel flange grooves merging at the approach, the upper face thereof having apex of the truncated V-shaped casting and wheel flange grooves, the outer wall of one the lower face of the said casting being pro- 15 groove being parallel with the inner edge of vided with a rail receiving groove, sub-- the fro-g, the outer wall of the other groove stantially as described.

being at an oblique angle to the outer edge In testimony whereof I hereunto alliX my of the frog, one end of the inner walls of signature in the presence of two witnesses.
