Serial No. 507,777.

To all whom it may concern:

Be it known that we, GEORGE SHIMP and ISAAC I-I. WILTON, citizens of the United States of America, residing at Patoka, in the county of Marion and State of Illinois, have invented new and useful Improvements in Railway-Switches, of which the following is a specification.

This invention relates to railway switches, and one of the principal objects of the same is to provide simpleand efficient means for simultaneously shifting the frog or rail section from one frog to another and for moving the switch points into proper position relatively to the movement of the frog or rail section.

Another object of the invention is to provide reliable and efficient mechanism for shifting the frog or rail section, locking the same in position and shifting the rail points all by the movement of a single lever.

Still another objectof the invention is to provide simple, reliable and efficient means or shifting the rail section or frog, locking the same 1n shifted position, moving the switch points by two movements of a single lever, means being provided for locking said lever in two positions.

These and other objects may be attained by means of the construction illustrated in the accompanying drawings, in which;-

Figure l is a plan view of a switch made in accordance with our invention. Fig. 2 is a top plan view of the switch stand. Fig. 3 is a vertical section of the same, showlng some of the parts of the switch-operating mechanism in section. Fig. 1 is a perspective view of a slotted lever adapted to actuate the frog-locking mechanism. Fig. 5 is a detail sectional view of the pivoted rail section or frog and the plate on which it is mounted. Fig. 6 is a detail sectional view of one end of said movable section or frog, showing the lever connection for operating the same.

Referring to the drawings, the numerals 1 designate the main track rails, and 2 are the side rails. Secured to the ties at the point of intersection of the side rails and one of the main track rails is a plate 3, said plate being provided with oppositely disposed slots l. Pivotally mounted at 5 upon the plate 3 is a movable rail section or fro 6. The frog 6 is pivoted centrally to the plate 3 by means of a threaded screw 7 extending to the bottom of the plate 3 into a socket in the lower side of the frog 6, and lock nuts 8 are applied to the end of the bolt, as shown in Fig. 5. At the opposite ends of the fro 6 levers 9 are pivotally connected to sai frog by means of threaded pins 10, said pins extending through the slots 1 in the late 3 and connected to the frog 6 on the un erside thereof, the levers 9 being pivoted upon the pins 10 and held in place by means of pins 11, as shown in Fig. 5. The levers 9 extend underneath the outer track rails 1 and are pivotally connected to hell crank levers 12, said bell crank levers being pivoted at 13 to a bar 1 1 secured to the ties. A bar 15 is pivotally connected to each of the bell crank levers, and attached to the bar 15 is a connecting rod 16 pivoted to a bell crank lever 17, said lever being pivoted at 18 to a bar 19 supported on the ties near the switch stand. Suitable stops 20 are provided at the sides of the rails 1 and 9. to insure proper alinement of the frog 6 with the rails'when shifted.

At the points of junction of they rails 1 and 2 bearing blocks 21 are secured, said bearing blocks each having a longitudinal opening therein through which projects a locking bar 22, said locking bars being longitudinally movable in the bearing blocks 21. Pivot'ally connected to the outer ends of the locking bars 22 are the levers 23, said levers being pivotally connected at 2i to bars 25 supported upon the ties. The levers 23 are pivoted at their outer ends to a connecting rod 26, said connecting rod extendin through keepers 27 supported on the ties, ant a spiral spring 28 surrounds the end of said connecting rod. The tension of the spring 28 is exerted to hold the connecting rod in position to lock the frog 6 in either of its adjusted positions. The connecting rod 26 is pivotally connected to an elbow lever 29 pivoted at 30 to one of the ties. Connected to the elbow lever 29 is a lever 31 adapted to be actuated by the movement of the lever at the switch stand, as will be hereinafter described.

The switch pomts 32 are pivotally connected to the bearing blocks 33, and near the ends of said switch points a cross bar 34 is connected said cross bar extending from one switch point to the other and extending under one of the rails to form an extension 35. Pivotally connected to the extension 35 is a lever 36.

The switch stand comprises the legs 37 provided with feet 38 securely bolted ties 39, said legs being connected at thejtop' by the table 40. Supported upon the table is a metal disk 41 havlng notches 42 and 43' formed therein. A curved slot 44 is formed in the disk 41 and in thetable 40, said slots ing ahole therein through which the shaft 45 passes. This bar is pivoted at 49 to a lever 50, said lever being pivoted at 51 to a slotted block 52 rigidly connected at 53 to the shaft 45. The lug 48 bears against a curved lever 54 pivoted at 55 on a lug 56 secured to the frame. The lever 54 is provided with a slot 57 in the curved upper portion thereof, and the shaft 45 extends through said slot. The opposite end of the lever is pivotally connected at 58 to the bar 31. Secured to the lower end of the shaft 45 is a projecting arm 59 adjustably secured to the shaft 45 by means of a set screw 60. Pivotally connected to the arm 59 is a bar 61, the outer end of-which is pivoted to the elbow lever 17, as shown in Fig. 1.

The operation of our invention may be briefly described as follows: hen the switch is in the position shown in Fig. 1 of the drawing and the main track is in operative condition, the lever 50 may be raised out of the notch 42 and moved to the left into the notch 48. The initial movement of the lever 50 forces the lug 48 downward, and this actuates the lever 54 to draw the bar 31 inward and to withdraw the locking bars 22 into the bearing blocks 21. A further movement of the lever 50 actuates the bar 61 and the connections for moving the switch points 32. and the frog 6 simultaneously, said frog being moved to a position to aline with the siding track 2. In this condition a train 'may be run from the main track on to the siding.

From the foregoing, it will be obvious that a switch made and operated in accordance with our invention will be reliable in use, quick to operate, will be locked in its adjusted position and can be installed at low cost.

We claim 1. A switch comprising a plate secured to the ties at the point of junction of the siding and the main track, a frog pivotally mounted on said Jlate, locking bars mounted in bearings to iock said frog in adjusted position, a switch stand, switch points, and switch mechanism for moving the locking bars, shifting the frog and moving the points by the movement of a single lever, said switch mechanism comprising a curved lever provided with a slot, connections extending to the points and an operating lever and lock.

2. A switch comprising a plate supported upon the ties, a frog pivoted to said plate, bearing blocks for said frog, locking bars extending through said bearing blocks, levers connected to said locking bars, a switch stand, switch points, a lever, a lock for said lever, connections between said lever and switch points, said connections comprising a pivoted two-armed lever having a curved and slotted upper end through which the operating lever extends.

In testimony whereof we aflix our signatures in presence of two witnesses.
