Beit kn'own'that I, JAMES S. Run), a citizen of the United States, residing at Harrisburg, in the county of Saline and State of Illinois, have invented certain new and use ful Improvements in Railway-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.

This invention relates to railway frogs.

One object of this invention is to generally improve upon devices of this character by providing an improved one-piece structure which combines excessive strength and utility with simplicity of construction and comparatively slight cost to manufacture and maintain.

Other objects and advantages will be pointed out or implied in the following details of description in connection with the accompanying drawings, in which:

Figure 1 is a perspective view of my improved frog. i

Fig. 2 is a longitudinal vertical sectional view, the section being taken substantially along the line 22 of Fig. 1.

Fig. 3 is a transverse sectional view, the section being taken substantially. along the line 3-3 of Fig. 1.

Fig. 4 is a detail sectional view along the line 1-4 of Fig. 1.

Fig. 5 is a transverse section taken along the line 5-5 of Fig. 1.

Referring to these drawings in detail, in which similar reference characters correspond with similar parts throughout the several views, the invention consists in the construction and arrangement of parts which will now be specifically described in detail, as follows: I

My invention comprises a one-piece frogbody of steel or other appropriate metal, and has a plane base or lower surface which is adapted to be seated upon a foundation of wood or other material, as illustrated, and spikes may be applied at any preferred points along its lateral. edges, a shelf or ledge being provided for the purpose of having the heads of the spikes seated thereon, as indicated at 1 in Fig. l of the drawings. The frog-body includes the usual railwings 2, the usual track-point 3, a pair of inwardly bowed walls 4, a pair of re-railing inclines 5, a pair of fish-plate arms6 which diverge from the toe end of the frog-body, and a fish-plate extension which projects from the heel end of the frog-body.

The fish-plate arms 6 have their inner surfaces formed to engage with and conform to the webs and heads of a pair of rails which are connected to the frog by means of these fish-plate arms, bolt-holes 8 being provided in these fish-plate arms or rail end. connections. On the other hand, the rail end connection or extension 7 has its outer surfaces shaped to conform to the webs and heads of the pair of rail ends which connect to this heel end of the frog, and bolt-holes 8 are provided also in this heel extension or rail connection 7. It will be seen, therefore, that the outer surfaces of both pairs of rails are engaged by this frog, that is, the surfaces (of the rails) opposite to those against which the flanges of the wheels rub and press. Therefore, all lateral pressure of the wheel-flanges against the wheel is transmitted by the wheel to the surfaces 9 and 10 of the rail connection rather than against the bolts which extend through the openings 8, thereby obtaining the greatest possible strength and durability of the rail end connections. 7

Each re-railing surface 5 is disposed between one of the wheel-guiding walls at and one of the wings 2, and this provides an effective and practical guide for directing the wheel (which has been derailed) on the frog and then to its proper position on the track.

The longitudinal groove through this frog has its bottom elevated at 11, so that the flanges of the wheels that pass thereover roll on this elevated bottom of the groove, thereby protecting the apex of the point 3 from contact with the tread of thewheel, thereby avoiding unnecessary shocks and damage resulting, from the shocks.

It is not intended to limit the invention to the exact details of construction and arrangement, as shown, but changes may be made within the scope of the inventive ideas as implied and claimed.

What I claim as my invention is:

1. In a railway frog, a one-piece frogbody including the usual track-point, the usual wings, track-rail connections extending from said wings, track rail-connections extending from the heel of said track-point, inwardly bowed wheehguiding walls extending up from the outer sides of said Wings, and re-i'ailing surfaces inclined to- Ward the toe end of the frog-body, each of these re-raihng surfaces being disposed between one of said Wings and one of said guiding Walls.

2. In a railway frog, a onep1ece body 111- cluding the usual track-point; the usual Wings, fish-plate connections extending from the wlngs at the toe end of the frog body and havlng inwardly fitClilg rail-engaging faces, a fish plate connectionextending from the track point at the heel end of the frog body,'and having outwardly facing rail-en- JAMES s.
