RAILROAD-SWITCH.

Application filed May 29, 1917.

To all whom it may concern:

Be it'known that I, EDMUND CRAnnooK JONES, a citizen of the United States, re siding in Cincinnati, in the county of Hamilton and State of Ohio, have invented new and useful Improvements in Railroad- Switches, of which the following is a specification.

An object of my invention is to produce an improved railroad switch in which the wheels of cars may pass the intersection of the crossing rails of a switch with no jarring or hammering action thereon, there by contributing to the greater smoothness of passage of the cars over the rails of switches as well as substantially eliminating the wear and loosening of the rail joints at intersecting points of switch rails.

This and other objects are attained in the switch herein described and illustrated in the drawings in which Figure 1 is a plan view of a switch embodying my invention, showing the switch elements set for passage of cars along the main line of track.

Fig. 2 is a plan view of my improved switch, showing the switch elements set for passage of cars from the main track onto a side track.

Fig. 3 is an inverted plan view of my improved switch, showing more clearly the operating mechanism of my switch, the parts thereof being set to retain the switch elements in the positions disclosed in Fig. 1.

Fig. 4 is a transverse sectional view taken on the line -l l of Fig. 3, of the frog of my improved switch, upon an enlarged scale.

Fig. 5 is a sectional view of a joint between links and levers in my improved switch construction, and taken on the line 55 of Fig. 2, upon an enlarged scale.

Fig. 6 is a transverse sectional View taken on the line 66 of Fig. 1, and upon an enlarged, scale.

My improved switch is disclosed as connecting a side track consisting of rails 7 and 7 with a main track consisting of rails 8 and 8, the usual shifting rails 9 and 9 being provided for diverting cars from the main to the side track or from the side to the main track. Located at the intersection of the inner rails 7 and 8 of the side and main tracks is a froglO embodying the principal feature of novelty of my improved construction and consisting of a turn table 11 of cylindrical shape and of heavy construc- Specification of Letters Patent.

tion having a groove 12 formed therein for the passage of the flanges of car wheels therethrough. This turn table is pivotally mounted in a socket formed by flanges 13 formed on a plate 14 to which is bolted or otherwise secured the converging ends of inner rails 7 and 8 and the converging ends of shifting rails 9, the plate being in turn secured to sleepers 15 and 16 of the tracks. The turn table is retained in the socket by means of a plate 17 which is secured to plate 1-1 as disclosed in Fig. 4 and which cooperates with an operating crank 18 which is held in position upon a tapered extension 19 of turn table 11 by means of a Washer 20 and lock nut 21.

Between the convergent and divergent ends of shifting rails 9 and 9, is a plate 22 which is secured to track sleepers 23 and 24. Upon a tapered extension 25 of this plate a swinging arm 26 is pivotally mounted, a washer 27 and adjustment nut 28 being provided for maintaining the arm in position thereon. One end of this arm is connected with a link 29 which connects itwith crank 18 of turn table 11. Located at the divergent ends of shifting rails 9 and 9 and pivotally mounted upon a plate 30 which is secured to a track sleeper 31, is a bell crank lever 32, the longer arm of which is con- 7 nected with a link 33 which connects it with the opposite end of arm 26. The opposite end of bell crank 32 to which link 33 is pivotally connected is pivotally connected with a coupling 34 which is secured to brace rod 35 which cooperates with a brace rod 36 in holding the shifting rails in proper spaced relation. This coupling 3 is connected with a rod 37 extending from switch stand 38 which is provided for throwing the switch.

Each of the joints between the links and the levers and between the links and the cranks is constructed somewhat as shown in Fig. 5 in which bell crank 32 is provided with a conical extension 39 upon which a washer and lock nut 40 are mounted for retaining the end of link 33 in position thereon. Figs. 4L and 6 also illustrate the manner of making connections, pivotal and otherwise, for the purpose of facilitating the taking up of lost motion existing in the operative mechanism of the switch, so that groove 12 of turn table 11 will be brought to register accurately with the rails when turned to either of the positions disclosed in Figs. 1 and 2, by the shifting of rails 9 and 9 to the respective positions disclosed in these figures.

Having thus described my invention What I claim is A railroad switch comprising a pair of shifting rails located between the outer rails of tracks to be connected, a rail shitting mechanism, a turn table located at the point of intersection of the inner rails of the tracks to be connected and consisting 1": a socket secured to the track sleepers, a grooved cylindrical member rotatively mounted in the socket and having an extension from the bottom thereof, a lever mounted on the extension, and a system of links and levers connecting the first mentioned lever, the shifting rails and the mechanism, the points of connection of the levers With the elements of the switch and of the levers with the links, being tapered to permit the taking up of lost motion between the mechanism, the turn table and the rails.

In Witness whereof, I afiix my signature in the presence of two Witnesses.

EDMUND CRADDOCK JONES.
