REVERSIBLE FROG.

Specification of Letters Patent.

Patented Nov. 16, 1969.

To all whom t may concern:

Be it known that we, WILLIAM II. DoT- 'rnn and RAPHAEL S. I-IAYs, citizens of the United States, residing at Carlisle, in the county of Cumberland and State of Pennsylvania, have invented certain new and useful Improvements in Reversible Frogs, of which the following is a specification.

The present improvement relates to reversible frogs and means for bracing the same, the object of the invention being to provide an improved reversible frog and brace therefor whereby the frog will not only be effectively braced against endwise as well as lateral movement or play, but is so connected to the ties that the frog can be readily reversed when wear on one side necessitates this.

In the drawings accompanying and forming a part of this specification, Figure 1 is a top view of this improved reversible frog, a part thereof in section, shown connected by these improved braces to a series of ties; Fig. 2 is a cross sectional view taken in line a-a, Fig. 1, looking toward the right; Fig. 8 is a perspective view of one portion of this improved frog; and Fig. 4 is a perspective view of this improved brace specially adapted for use with this improved frog.

Similar characters of reference indicate corresponding parts throughout the figures of the drawings.

In the embodiment shown the frog 2, which is preferably made of hard metal, such for instance as manganese steel, and of an integral structure, has its upper and lower rail or tread surfaces, 3 and 4; respectively, similarly formed, so that when the upper rail surface has become so much worn as to be unfit for further use the frog can be reversed. In the present embodiment the top and bottom rail surfaces, as stated, are the same in shape and size throughout, and this therefore produces a differently shaped recess or space 5 between such top and bottom rail surfaces from those which are ordinarily found in standard rails between the head and the base. Therefore, in order to properly brace the frog, we have provided it at each side, between the heads 3 and 4, and at proper intervals along the same, with ribs 6 cast integral with the frogs. These ribs are spaced apart to form recesses 7 at intervals along the sides of the rail portions of the frog and at the outer sides of such frog. The ribs on one side of the frog in the present embodiment are shown located opposite to the ribs on the other side of the frog, whereby both sides of the frog may be braced to the same tie.

The braces in the present instance comprise a bottom plate 10 and an upright plate 11, connected together by a curved or rounded portion 12 conforming to the curved surface 18 of the rail at the inner side of the tread surface thereof, thereby to permit the upright plate 11 to fit snugly in its recess 7 between the ribs, which latter are shown as flush with the outer side faces 14 of the rail portions. The two plates of this angle iron brace are connected or braced by an inclined member or rib 15 formed or cast with such plates, the brace being preferably made of malleable iron.

By the construction described it will be observed that when the compromise splice bars connecting the frogs to the standard rails are removed it will be necessary only to take olf the braces at one side of the frog in order to reverse the frog, and that, furthermore, by this improved construction of frog and brace the endwise movement or play, as well as lateral movement or play of the frog is prevented, since the braces, fitting snugly into the recesses formed by the ribs, are practically seated in sockets, each socket made up of a pair of ribs and the opposing faces 13 and 1G of the tread surfaces of the rail. Thus these braces not only act to prevent the endwise as well as lateral play, but by their mode of connection with the rails materially assist in supw porting the rails, since the end surface 17 of the upper plate is in contact with the under wall 16 of the tread surface of the rail, and thus very materially tends to support and brace the same. Furthermore, these ribs not only form recesses or sockets for the braces, but they also reinforce and strengthen the rails, thus furnishing a much `stronger and more durable rail than heretofore.

AIn practice the flat plates of the braces may be spiked through a supporting plate 20 secured to each tie, whereby the braces of each tie will rest flatly and evenly in pot 9. A hard metal reversible frog having sition upon the metal plate which extends duplicate rail head surfaces and provided at under the frog.
