GEORGE (l. LUCAS, OF CLEVELAND, OHIO.

RAILWAY-FROG.

' Specification of Letters Patent.

Patented July 6, 1909.

Application led January 14, 1909. Lv-Seriai No. 472,158.

that class in which the center portion or frog body, in order to withstand hard service, is .made oi' some especially hard and tough material, such as manganese steel.

The object of the invention is to produce a frog especially adapted to hard servico, and so constructed that very strong support is affordedagainst vertical as well as horizontal to the toe extension G. Filler blocks displacement of any of the parts.

Further. objects of the invention will hereinafter appear. I

The drawings show two embodiments of the invention in the best form known to Figure l is a plan viewof a railway frog embodying the invention; Figs. 2, 3, and 4l are transverse sectional views of the same on the lines QHZ, 31-3,4.4, respectively, of Fig. 1 looking in the direction of the arrows. Fig. 5 `is a plan view of the frog body de- Vtached. Fig. 6 is a transverse sectional view of a modiiication on thc same plane as Fig. 2.

Referring' to the drawings, A represents a frog body which isiprcfcrably a casting or forgii'ig of manganese steel or'other suitable material of the lorm shown in the drawings. The frog rails are marked B and C.

The frog body A has a point D against which the two track rails B abut and pret erably aA heel extension E here shown extending between said rails. The frog body is also provided with the flange grooves F and preferably the toeextension G adaptedtoextend between the frog rails C. If desired, a ller block H may also be provided ad'lacent mei' also be provided at the4 other end of the frog between the wings K and rails B.

" The frog rails C extend throughout the length of the frog body and project ,to form Wing rails, as shown. Theirheads are cut awa arid interrupted across the entire Width of t eirtread surface between the points J and K and replaced by the lateral tread portions or heads L of the frog body. Preferably the channels O on the outer sides of the frog rails are left entirely unim aired to fit splice bars or angles, and only t e inside portion and the upper portions of the heads of rails C head Q interloclis with the are out away as shown in the section and revplaced by the tread portions L of the frog body. lrcicrably the heads or treads L are providod'with the downward extending lips or ilanges P lor coacting with and gripping the remaining portions of the rail heads Q, as shown in Fig. 2, to aid in preventing transverse movements in the structure. Suitable lishing plates, preferably in the form of angle bars R, extend along the frog rails C to give additional strength and security and the parts are bolted together at frequent intervals by bolts S. Inclines T on the frog body for receiving the false langes of the treads ol` worn wheels are drown where the head portions L Widen out from therail C to form easier surfaces.

It will be seen that the toe extension G, which extends beneath the heads of rails C, as shown, will serve to lock the frog body down to the rails and support the rail heads lfrom beneath, and toward the other end of the frog at K a similar purpose is served by the extension of the frog body beneath the heads of the Wing rails and by the extension E beneath the heads of the rails B. These provisions ali'ord strong support against upward vertical displacements of the frog body in respect to the rails.

The modification of the invention shown in Fig. 6 is similar except that the downward extending lips P of the treads orhcads L of the frog body are omitted, and that an inward projecting part N of the cut-away rail frog body to aid in holding it down.

It will be seen that according to this invention strong resistance is allorded in, the structure to longitudinal, to transverse; and to vertical movements of the parts. 4The frog body and rails are interlocked and clam ed securely together. The structure is simp e. Thev parts are readily assembled. The frog is eflicient in use and easy to construct.

I claim and desire to obtain by Letters Patl ent the following: 1. A railway frog having a lrog body provided wlth tread portions and llange grooves,

and one or more frog rails extending` through` out the length of the iro body, said rail being vcut away and interrupted across the entire heads of the eut-away rail or rails to prevent vertical displacement.

2. A railway frog having a. frog body provided with treed portions Aand llenge grooves, and one or more frog rails having the channel on the outside continuous and having the upper portion of the head entirely out away for an interval and replaced by the tread of the frog body, and u splice bar or angle ber secured in seid channehsaidfrog body having one or more portions extending beneath the head or heads of the out-away rail or rails to prevent vertical displacement.

3. A railway flogr presenting in cross section it frogjr body that overlies e. eut-away portion of one or more of the frog rail heals, leavingr a portion of such head or heads for oom-,tion therewith, said portion .including an eeeeeo l inward rejecting part that is tted to the frog bo y.

4. A railway frog presenting in cross section e frog bodyv that overlies a out-away portion vof one or more of the frog raiLheads, leaving e. portion of such head or heads for Coaotion therewith, one or more of said rails extending beyond said cut-away portion for a substantiel dista-nce end forming one or more Wing rails beneath the heads of which the frog body extends.

In testimony whereof l have signed this specification in the presence of two subscribing Witnesses, January 12th 1909.

. GEORGE C. LUCAS.
