RAILROAD-iFROG.

SPECIFICATION forming part of Letters Patent No. 734,132, dated July 21, 1903. Application-filed May 21, 1903. Serial No. 15 8,158. (No model.)

To all whom t may concern:

Be it known that I, RAYMOND NovINGER, a citizen of the United States, residing at Centerview, in the county of Dauphin and State of Pennsylvania, have invented a certain new and usefulRailroad-Frog, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to railroad-frogs, the object in view being to provide a simple, effective, and reliable frog in which the movable parts are rendered self-adjusting, the frog comprising a pair of wing-rails which are terminally pivoted at one end and which are yieldingly held toward the point of the frog by means of a spring device which is located wholly between the wing-rails whereby said spring device is protected from injury and the operation of the wing portions of the rails made certain and reliable. i

With the above and other objects in View, the nature of which will more fully appear as the description proceeds, Vthe invention consists in the novel construction, combination, and arrangement of parts, as hereinafter fully described, illustrated, and claimed.

In the accompanying drawings, Figure lis plan view of a railroad-frog constructed in accordance with the present invention, showing the spring device partly in section. Fig. 2 is a cross-section on the line 2 2 of Fig. l. Fig. 3 is a cross-section taken adjacent to the traveler or guide-bar. x

Like reference-numerals designate corresponding parts in all ligures of the drawings.

Referring to the drawings, 1 designates a base-plate of suitable size, the same being adapted to rest upon and be secured permanently to the ties of the road-bed. 4The point 2 of the frog is formed by the meeting extremities of the converging rail-sections 3, which arejointed and tenoned into each other, as shown at 4. Extending transversely through the rail-,sections 3 is aA traveler or guide-bar 5, located a suitable distanceabove the base-plate and having its opposite end vsupported by means of blocks 6, which are interposed between the traveler-bar and baseplate, as best shown in Fig. 3. The travelerbar 5 is held stationaryand serves as a guide for the wings of the wing-rails.

7 designates the wing-rails, which are terminally pivoted at 8 to a stay-bar 9, extending transversely of the track and secured tov a tie or anchored in any other convenient manner. The wing-rails 7 converge toward the point of the frog and after extending beyond the point of the frog they are bent .to flare outwardly in opposite directions, thereb'y forming the wings 10, which lie on opposite sides of the frog, the extremities of the wings being bent outward, as shown at 11, to insure the proper entrance of the iianges of the wheels between the wings and the point of the frog in a manner readily understood by those conversant with the art to which this invention appertains.

At the points of junction of the wings 10 y with the main body portions of the wing-rails 7 the latter are oset outwardly in opposite directions, as shown at 12, and within said offsets l2 are securely fastened hard-metal reinforce-blocks 13, having their inner adjacent faces reversely beveled, the beveled faces forming continuations of and being exactly in alinement with the corresponding inner edges of the wings l0 and the wing-rails 7, while the vertices 14 of the reinforce-blocks liel exactly opposite each other and close to the extremity of the point of the block, as clearly illustrated in Fig. 1.

Between the'wing-rails 7 is arranged a spring device consisting lof a spring 14, arranged within a cylindrical spring box or housing 15 and a tension-bolt 16. The spring box or housing 15 is bolted, as shown at 17, to the web 18 of one of the wing-rails, while the tension-bolt 16 is provided at one end with a head or shoulder 19, which engages the end of the spring, said bolt passing through thespringand thespring-boxandalsothrough the web ol the opposite rail, where it is held and made adjustable by means of a tensionnut 20. The spring device as a whole is located entirely between the pivoted wing-rails, and is thereby protected from injury. The

spring device exerts its tension to yieldingly hold the wings-toward the point of the frog, at the same time allowing either one of the wings to yield away from the point of the frog as a train passes over the same.

21 designates a pair of wing-rail checks or inforce-blocks held in said osets and having reversely-beveled adjacent faces and oppo- 15 sitely-arranged vertices, and a spring located Wholly between the pivoted wing-rails and acting to yieldingly hold the wings toward the frog-point, substantially as described.

In testimony whereof I aix my signature zo in presence of two witnesses.

RAYMOND NOVINGER.
