REINFORCED FROG.

Specification of Letters Patent. Patented Feb. 14, 1911..

Application filed August 5, 1910. Serial No. 575,839.

To all whom it may concern:

Be it known that I, JAMES BOORMAN STRONG, a citizen of the United States, residing at Hillburn, in the county of Rockland and State of New York, have invented certain new and useful Improvements in Reinforced Frogs, of which the following is a specification.

The invention relates to means for reinforcing railway frogs, particularly to frogs cast from manganese steel or a similar material, and the invention consists in the new and novel features of construct-ion and combinations of parts hereinafter set forth and claimed.

Heretofore it has not been usual to provide a reinforcement of any kind for frogs of the solid cast type. It is found, however, that a continuous reinforcement of some kind is desirable in order to avoid even the possibility of an accident due to the break ing of such frogs, and the object of this invention is to provide a suitable reinforcement which will be sufficiently strong to afford the necessary protection against breaks age, but which will be simple in construction and easy to assemble, and which will be practical for use in connection with a material such as manganese steel that is extremely diflicult to work or machine.

In the accompanying drawings: Figure 1 is a plan view of a frog embodying my invention. -Fig. 2 is a side elevation of the same. Figs. 3, 4L, 5, 6 and 7 are sectional views on the lines rd-3, 1%, 5-5, (3-43 and 77 of Fig. 1.

The frog is cast in a single piece and comprises the point 1, wings 2, heel 3, and the heel and tongue extensions 4 and 5 respec tively. Track rails 6 are bolted to the tongue and heel extensions in the usual manner. The frog piece is also provided with notches 7 in its base at suitable intervals to receive the spikes.

In order to hold the parts of the frog together in case of breakage thereof, and also to hold the track rails securely against displacement, a strap or reinforcing bar 9 is bolted to each side of the frog throughout its entire length, and is also extended at both ends to overlap the joints between the track rails and the frog. Said bar may comprise a flat piece of metal corresponding in section to a splice bar or it may be of any other desired section and it is provided with a bend or angle 11 to engage with the flaring ends 12 of the wings. Said bar is recessed in said bend or angle 11 so as to provide a fiangeway of equal depth with the liangeway of the frog and may be secured to the frog in any well known manner, as by the bolts 14:, and the bolts 15, which also secure the track rails to the fro The bolts are placed at intervals throughout the length of the frog and pass entirely through the frog and both of the bars so that they are in effect tie rods for all parts of the frog.

By means of this construction accidents due to the breakage of the cast frog may be avoided. At the same time an extremely strong and effective splice is provided for the joint between the track rails and the frog. Since the bar extends the full length of the frog, and projects alongside the track rail at both ends of the frog, an extremely strong and rigid reinforcement is thus provided which will normally hold the parts together for a considerable length of time, even though breakage occurs. It will be obvious that the frog piece may be made solid or may be of any desired section for the sake of lightness, without departing from the invention provided the means set forth in the following claims be employed.

I claim as my invention:

' 1. In a reinforced frog the combination with a cast frog comprising a point portion, flaring wings, and tongue and heel extensions formed integral with each other, of track rails secured to said extensions, a continuous reinforcing bar extending the full length of the frog and overlapping the joint between the frog and the track rails at each end of the frog, said frog and bar being secured together by bolts passing entirely through the frog at intervals throughout its entire length.

2. In a reinforced frog, the combination with a cast frog piece comprising a point portion, wing rails having flaring ends and heel and tongue extensions formed integral with each other, of track rails secured to said extensions, and a continuous reinforcing bar extending the full length of the frog and having a bend therein to overlap the flaring ends of the wing rails, said reinforcing bar having a recess provided in said bend to register with the flangeway of the frog substantially as described.

3. In a reinforced frog the combination with a cast frog piece comprising a point portion, wings having flaring ends, and heel and tongue extensions formed integral with ing entirely through said frog and reinforceach other, of rails secured to sand eXten 111g bars at lntervals throughout the length slons, continuous reinforcing bars extendlng of the frog, substantlally as described.
