RAILWAY-FROG.

Original No. 790,629, dated May 23, 1905. Application for reissue filed June 25, 1906- Serial 110323396 To all whom it may] concern:

- Be it known that 1, JOHN E. GRAHAM, a

citizen of the United States residing at Salem, in the county of Roanoke and State of 'Vir inia, have invented a new and useful Rai way-Frog, of which the following is a specification. This invention relates to railway-frogs. The objects of the invention are to simplify the construction and increase the efliciency of such devices, to dispense with the employ tively to the frog, and, finally, generally to improve and strengthen devices of this character With the above and other objects in view, as will appear as the nature of the invention is better understood, the same consists in the novel construction and combination of parts of a railway-frog, as will be hereinafter fully described and claimed.

In the accompanying drawings, formin a part of this'specification, and inwhich 516 characters of reference indicate corresponding parts,- there is illustrated one form of embodiment of the invention capable of carrying the same into practical operation, it being understood that the elements therein exhibitcrl may be varied or changed as to shape, proportion, and exact manner of assemblage without departing from the spirit thereof, and in t iese drawings Figure 1 is a view in plan, exhibiting a frog construpted in accordance with the present invention. Fig. 2 is a view in elevation, partly in section, showing the cooperative relation between the frog-rails, frog, and a car-wheel when the latter is traveling overthe p is a sectional detail view of a slightly-modified form of the invention.

Fig. 3 is a perspective detail view 1 of th frog with its parts separated. Fig. 4 i

Referring to the drawings, 1 and 2 nate a pair of frog-rails, and 3 a frog-point. These parts may be of the usual or any preferred construction, and therefore need no detailed description.

The present invention resides in the novel construction of the frog proper, the same being shown in detail in Fig. 3-and comprising two frog-blocks4 and 5 and a spacing-block 6. Each of the frog-blocks is a counter art of the other, and a description of one wil therefore serve for both. The block may be either rolled or cast, as may be preferred, and is provided on its lower outer side with a base-fiange 7, at its upper outer side with a wheel-flange 8, on its inner side with a railtread seat 9, and adjacent to the wheel-flange with a wheel-rim tread 10. The block is formed on proper lines and curves to cause the wheels to be switched from one track to another in the usual manner and generally conforms to the lines of an ordinary frog. When the two frog-blocks are assembled, as shown in Fig. 1, the wheel-flanges converge toward. each other in the direction of the frogpoint, thereby causing the entering end of the frog to present an inclined or wedge face to the side of the car or engine wheels, which will operate to shift the same gradually and smoothly onto the frog-point, the en tering.

ends of the wheel-flanges being sLghtly curved away from the frog-rails, thus to prevent any impact between the sides of the wheels and the fian 'es on the initial entry of the former into the 0g; Of course it will be understood that the opposed faces of the two frog-blocks are oppositely curved, thus to secure the pro er shiftin of the car-wheels .from one of t e frog-rails to the other on either side.

The spacing-block 6 is preferably shaped to conform accurately to the opposed faces 11 and 12sof the frog-blocks, and the three parts are held combined by bolts 13, in this instance three in num ber, which pass through the body portions of the frog-blocks and of the spacing-block, suitable bolt-openings 14 being provided for this pur 'iose.

As shown in Fig. 2, the under side of the frog members closely impinge and inclose the bases 15 of the frog-rails, and to secure this result the under face of the-spacing-block is angularly or reversely inclined, as. shown at each of the blocks,

1 flanges 8 on the manner in which all the 16, to fit against the upper sides of the inner portions of the bases, while the under face of each of the frog-blocks is upwardly inclined, as at 17, to bear upon the upper faces of the outer portions of the bases. In providing the inclined ortio'ns 17 there is formed a longitudinal s oulder 18 on the outer side of and these shoulders bear against the outer edges of the bases and operate ositivelyto clamp them together and to ho (1 them from movement, while the spacing-block also'cooperatcs to prevent any.

inward movement of 'tncfrog-rails relatively to each other. i I V In order tojprevent any lateral shifting of the frogoint 3, one end of the spacing-block is provi ed with a triangular.vertically disposed groove or recess 10, in which the terminal of the frog-point rests, as clearly shown in Fig. 1. I

a As shown in Figs. 1 and 2, the wheel-rim treads incline slightly toward the center of the frog, while the upper faces of; the frograil treads are horizontal; but, as shown in Fig. 4, both the wheel-rim treads and the uper faces of the frog-rails may be inclined, thus to conform accurately to the periphery or tread of the car-wheels.

To increase the life of the frog and to com.- ensate for wear-of the flanges 8, liners or fillers 2 0 may be employed, which will be disposed bet-ween the inner faces of the frogblccks and" the webs of the frog-rails, as shown in Fig. 4, and as the wheel-flanges wear a linerma be removed and the blocks again positioneg for wear all danger of the frog-point being struck by the wheel-flange is obviated. This feature will be found of 'n ortance, inasmuch as by the provision of t to liners the removal of a frog-block when its flange becomes Worn is rendered unnecessary, thereby effectinglarge saving to railway companies.

It wilLbe seen from the foregoing description that by the provision of the wheel- 7 frog-blocks the employment of the ordinary guard-rails isrendered unnecessary and that these wheel-flanges, or rather guard-flanges, will operate positively to cause the car-wheels to be shifted from one of the frog-rails to the other. By reason of the rail-tread s ats 9 a solid bearing is provided for th under faces of the frog-rail treads, and, further, these are caused to present, in combination with. the wixeel rim treads 10, a practically {lat which the wheels will tra 'el.

and combined't-here will be no possibility ol" a frog-rail becomingseparated from the frog 1 to take place with proper nor for the same the bolts 13, which the frog-point so long as pass through the frog-blocks, frog-rails, and.

spacing-blocks, remain in position.

By constructing the frog-blocks and. spacand by thus compensating guard-flange, and a spacingsurfare over l (living to the i parts are constructed 1 the device for ready adoption when desired.
