FRANK ROBINSON, OF OLIMAX, MICHIGAN.

RAI LWAY-CROSSING.

SPECIFICATION forming part of Letters Patent No. 351,403, dated October 26. 1886- Application filed April 14, 1886. Serial No. 198,847.

To all whom it may concern:

Be it known that I, FRANK ROBINSON, of the village of Climax, in the county of Kalamazoo and State of Michigan, and a citizen of the United States, have invented certain new and useful Improvements in Railway-Crossings, of which the following is a specification, reference being had to the accompanying drawings, forming a part thereof, and wherein like letters and figures of reference indicate corresponding parts in all the figures.

Figure 1 is a plan view of the main line of a railway with the ordinary switch and side track crossing diver ent thereform, at which point is clearly seen my new reciprocating substitute for the fixed frog usually employed. Fig. 2 represents an enlarged view in cross-section of the rail-section, turning-plate, and bedplate, and Fig. 3 shows the same in central longitudinal section on the line .r a', Fig. 2, with the whole resting 011 ordinary railwayties, t f 2f 25.

The object of my invention is to dispense with the destructive and dangerous fixed wedge-shaped frog hitherto used in connec tion with the switch at diagonal or divergent crossings, and to provide, in lieu thereof, a continuous rail at this point, thus doing away entirely with the pounding, destructive, and

dangerous difficulties and extreme hazard at-" tending the employment of wedge-shaped and oblique openings at the rail ends. Other obvious advantages accrue to the use of my improvement as will hereinafter appear.

A A, Fig. 1, represent the main line of a railway, and B B the divergent siding, into which the cars are directed from the movable rail ends A A, or by means of the switchlever S. a

0 represents a rail-sectionsay seven feet, or any convenient length which'is removably secured to a centrally-pivoted vibratory platform or table, D. (See Fig. 2.) This platform frog-plate or table D is provided with a circular depression depending from its under side, which forms a central pivot or point, on which the table D turns by means of a corresponding circular opening in the fixed plate E, immediately beneath, which latter plate is firmly fixed to the usual railway-ties,t t t t.

The fixed bed-plate E should be somewhat longer than the table D and rail 0, for the purpose of afiording a common support for the rail ends and for the lugs or stops Z N Z.

(No model.)

The vibratory rail 0 is removably fixed to the turn-table D by means of securing-plates a a and bolts ffff. The plates at a, being secured to the plate D by independent fastenings, as shown, permit of the ready sliding of the removable rail C from its dovetail-shaped rest, Fig. 2.

A central circular plate, F, situated imme diately underneath plate E and secured by the bolts and nuts I) b b b, firmly fixes the parts together and to the turn-table and railwaybed.

A reach-rod, r, connects with a reciprocating lever, G, which is provided with suitable arms and rods, r 0",whereby the table is turned simultaneously with the switching device or standard S, as shown in Fig. 1. Hence it becomes evident that whenever the ends of the rails A A shall be made to register with the siding B B the reciprocating table and rail 0,

in obedience to the impulse operating both the switch and reciprocating table, the crossing at the point heretofore occupied by the frog is herein provided with a continuous rail throughout, as at other points of the track, and does away entirely with the wear and tear, difficulty, and damages heretofore found inseparable from the use of fixed frogs and diagonal disconnected railway-rails.

Having thus fully described my invention and its practical advantages and mode of op eration, what Iclaim, and desire to secure by Letters Patent of the United States, is-

1. The plates a a, forming undercut ways for the flanges of rail 0, and independently fastened to plateD, to allow the section-rail O to be easily detached, as set forth.

2. The plate D, having a central integral bottom, a fast plate, E, provided with a bearing for said pivot, and a bottom plate, F, overlapping plate E, in combination with the bolts b, carrying nuts at their upper ends,
