JAMES BOORMAN STRONG, or HILLBURKAND eno'non ELLswon'rn HARING, OF SUFFERN,

. NEW YORK, ASSIGNORS TO RAMAPO IRON WORKS, OF HILLBUIt MNEW YORK, A CORPO- RATION OF. NEW YORK To all whom it may concern:

therein :Be itknown that we, JAMES BOORMAN STRONG and GEORGE ELLsWoRrH HARING, citizens of the United States, and residents of Hillb'urn, in the county of Rockland and State of New York, and of Suflerm'in the countyof Rockland and State of New York, respectively, have invented certain new and useful Improvements in Railway-Frogs, of

which the following is a specification.

Our invention relates to improvements in railway frogs wherein the frog bloc-k is made of a hard material, such as manganese steel, which'is especially adapted to withstand the severe wear to which-such structures are sub- Jected, and the invention consists in the new of construction and comparts hereinafter set forth and and novel features bination of claimed.

' In the accompanying drawings Figure 1 i is a plan view of a railway frog embodying our invention. Figs. 2 to 7 represent crosssections on the lines2 2, 33, 44, 5-5, 6-6 and 7-7 respectively in Fig. 1.

The stock or wing rails A A and the main or point rails B B are of any desired section and material. The frog block 0 is preferably rnade of a material especially adapted to resist wear, such as manganese steel, and comprises a front or toe portion, a central or chock portion and a rear or heel portion. Throughout its entire length the frog block rests upon and is supported by the bases of the adjacent rails and is preferably arched in section to save material and to distribute the weight properly. The front or toe portion of the frog block seats in the space be tween the heads and the bases of the wing rails and extends forward, as at 0, through the throat of the frog in place of the usual filler or spacing block. The central portion has a point e integral therewith and is provided with flange ways or grooves 0 formed by the sides of the point and up wardly projecting flanges or inserts c which are also integral with thefrog block. Said inserts are provided. with horizontally projecting flanges 0 adapted to scatinrecesses Speeificationof Letters Patent. Application filed April-7, 1908. Serial No. 425,644.

of the wing rails, as at a? so that the insert will form more than one halfof the treads throughout the portions of the wing rails opposite the point 0 The webs of thewing rails are .left intact and of uniform section throughout, so that the rigidity and strength of the rails is not impaired. i I

' The rear portion ofthe frog block extends rearward a suitable distance between the main or point rails and is'beveled at its ex treme end to. form a heel riser 0. At the junction with the frog block the heads of the point rails are cut away or beveled to fit to the frog-block and near the ends of the rails the heads are cut entirely away and the webs 12 seat in recesses formed by-outwardl extendim flan es 0 which'are formed cupy the places of the rail heads and provide treads for the wheels. upon the webs of the pointrails and provide means for preventing vertical movement thereof with relation to the frog block, in addition to belts 'or rivets d. All the parts of the frog, including the wing rails, point rails, and the frog block are readily secured together by suitable means, such as large bolts" D in addition to the bolts and rivets d and the overlapping parts.

By the construction above described, a

frog is produced, which requires a minimum of material relative to its strength, rigidity and wearing qualities. The parts are easily assembled and in case of injury or wear the can be easily removed and It is obvious that various changes in the details can be made, withoutdeparting from the invention as herein shown, and claimed.

We claim as our invention: 1. In a railway frog the combination with Said flanges seat integral with the frog block and which 00- I wing rails having their webs of uniform section and having the tread portion of their heads continuous and providedwith recesses, of a frog block seati :ig on the bases of the wing engaging said recesses. 2. In a railway frog the combination with wing rails having the tread portion of their hc'adscontinuous and provided with recesses extending more than one half the width of the tread of said rails, of a frog blockprovided with horizontal flanges seating in said r-ocesscs.

4 In a railway frog the combination with point rails having their heads partly removed of a frog block secured to the point rails and provided with flanges occufpying the laces of. such removed portions 0 the head of the point rails.

5. In a railway frog the combination with of a frog block between said .point rails provided with flanges occupying the place of resting upon the webs of said .point rails.

6. In a railway frog the combination with a frog block'provided with recesses, of oint rails having their heads removed an the webs engaging in said recesses.

7. In a railway frog the combination with by outwardly extending flanges integral'with said frog block, of point rails having their recesses.

8. In a railwayifrog the combination with rails and point rails respectively.

9. In a railway frog the combination wltn wing rails andpoint rails of a frog block hav-. ing a toe portion which projects through the throat of the frog, a central portion overlaping the wing rails, and a rear portion overapping the point rails.

10. In a railway frog, the combinationwithi the wing and point rails of a frog block com-- prising a toe ormed integr therewith, acentral portion flanges overlapping the wing rails and a rear portion having outwardly extending flanges overla ping the point rails.

11. n a railway frog, a rail having the tread portion of its head provided with a recess which extendsbeyond the plane-of the web of the rail. I
