JOHN TOIH, or JOLIET, ILLINOIS.

SWITCH-THROWING DEVICE.

Specification of Letters Patent.

Patented Sept. 2, 1 913.

Application filed April 20, 1911. Serial No. 622,239.

To all whom it may concern I Be it known that I, J on Tom, a subject of the King of Hungary, residing at Joliet, in the county of WVill and State of Illinois, have invented certain new and useful Improvements in Switch-'lln-owing Devices, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to a switch throwing device, and the objects of my invention are to provide automatic means for throwing a switch while a train is in motion, and novel means for restoring the switch to its normal position after a train has passed over the same.

Other objects of my invention are to provide a switch throwing device that can be used in connection with a semaphore or visible signal, and to accomplish the above results by a device that is simple in construction, applicable to the present type of railroad equipment and highly etlicient for insuring the safe passage of trains over tracks.

WVith the above and other objects in view, the invention resides in the novel construction, combination and arrangement of parts to be hereinafter specifically described and then claimed, and reference will now be had to the drawings, wherein Figure 1 is a plan of a switch throwing device in accordance with this invention, Fig. 2 is an enlarged plan of the track equipment, Fig. 3 is a longitudinal sectional view of the same, Fig. 4t is a front elevation of the train equipment, Fig. 5 is a side elevation of the same, Fig. 6 is an enlarged ver tical sectional view of a signal forming part of the switch throwing device, and Fig. 7 is a longitudinal sectional view of the same. The reference numeral 1 denotes ties or sleepers adapted to support rails 2 and 3, the rails 2 representing a main track and the rails 3 the same track or a siding track located some distance from the main track 2, in order to provide sufficient space for a switch adapted to control the passage of a train on the main and siding tracks.

Mounted upon the ties 1 between the main rails 2 are the lateral flanges 4c of a casing 5 adapted to fit between the ties 1. The casing 5 has a semicircular recess (3 and mounted. upon said casing at the sides of the recess 6 are bearings 7 for a shaft 8, said shaft extending through one of the main ads 2 into bearings 9, carried by a frame 10 located to one side of the main track.

Mounted upon the shaft 8 in the recess 6 is an auxiliary actuating wheel 11. having a plurality of equally spaced radially disposed arms 12 and an integral pinion 113. The pinion 13 can have circunlferentially arranged teeth or conform to a sector-gear, the former being preferable, said pinion meshing with a longitudinal rack 14. movably mounted upon rollers 15 arranged in sockets 16 provided therefor in the casing 5. The casing has longitudinally alining openings 17 providing clearance for the rack 14. The rack 14 is pivotally connected, as at 18 to a reach-rod 19. The rod 19 is pivotally connected, as at 20 to a lever 21 fulcrumed upon a pin 22 mounted transversely of an extension 23 of a casing 24. The casing 24 is located between the rails 3 and has a recess 25, similar to the casing 5.

Mounted upon the casing 24 are bearings 26 for a shaft 27 and mounted upon the shaft 27 is a main actuating wheel 28 having radially disposed arms 29 corresponding in number to the arms 12 of the actuating wheel 11. The shaft 27 has a crank 30 and this crank is pivotally connected by a rod 31 to the lever 21. The rod 81 extends through an opening 33 provided therefor in the casing 24.

The shaft 8 within the frame 10 has crank portions 33 and 3 1 and these crank portions are connected by links 35 to rods 36 which are connected, as at 37 to racks 38 and 39. The racks 3S and 39 extend through openings provided therefor in a housing d0 mounted upon a base 41, adjacent to the juncture of the rails 2 and 3 or at the switch controlling the passage of a train over said rails. The racks are movably supported upon rollers .1-2 arranged in bearings 43, carried by the base L1, and said racks mesh with large pinions si l; and 4-5 loosely mounted upon a shaft 46 mounted in a bearing 47 provided therefor in the housing 40. The loosely mounted pinions have the confronting faces thereof provided with sector-gears l8 and these gears mesh with a horizontal beveled gear wheel 4-1) mounted upon a vertical signal shaft 50 rotatably supported by the bearing 17. The upper end of the shaft extends through an opening 51 provided therefor in the housing 410, said shaft having balance arms and a visible signal or lantern 53. The lower end of the shaft is revolubly supported in a hearing 5% provided therefor in the base 4:1, and

mounted upon the lower end of the shaft is a disk 55 to which can be connected a switch throwing rod 56 for throwing the switch ing a longitudinally extending portion 61 and a horizontally disposed portion 61 and a lever 62. The lever 62 extends through a curved guide 63, carried by the support (Set of the bracket 57. The curved guide 63 has flat springs 65 upon the inner side thereof and at the ends for holding the lever 62 in an adjusted position.

To throw the switch tongue, the lever 62 is swung to the upper ends of the guides 63 and is held thereby with the L-shaped arm lowered. The horizontal portion (31 of the L-shaped arm is then in the path of one of the arms 29 of the actuating wheel 28 of the track equipment. When one of the arms 29 is struck, by the horizontal portion 61 of the L-shaped arm the actuating wheel 28 is partially rotated, and through the medium of the rods 31 and 19 and the lever 21, the rack 14 is shifted. When this rack is shifted the actuating wheel 11 is moved to rotate the shaft 8, and as said shaft is rotated, the racks 38 and 39 are moved. These racks through the medium of the pinions a l: and 4:5, sector gears 48 and gear wheel 4.9 partially rotate the shaft 50. In partially rotating the shaft 50, the switch tongue is thrown through the medium of the rod 56 and the signal 53 is set. 7

As the actuating wheel 11 is located some distance from the wheel 28, the actuating wheel 11 will not be engaged by the horizontal portion 61 of the L-shaped arm until the locomotive or train has passed over the while in the drawings there is illustrated a preferred embodiment of the invention, it

"is to be understoodthat the structural elements thereof are susceptible to such changes as fall within'the scope of the appended claims.

What I claim is A switch throwing device comprising a main and an auxiliary actuating wheel spaced from each other and adapted to be operated in unison, radial contact arms projecting from each of said actuating wheels, casings with basin shaped sockets therein, said wheels trunnioned upon the tops of said casings and extending within said sockets, the casing of said main wheel having alining openings therethrough communicating with said socket, said auxiliary wheel provided with a reduced side having teeth conforming to a sector-gear, a longitudinal rack engaging with said teeth and extending through said openings, a reach rod connected to said rack, a lever pivoted at one end to said reach rod, a shaft upon which said main actuating wheel is mounted, a crank projecting from said shaft, a rod attached to said crank and to the other arm of said lever, a vertically disposed switch rod operating shaft, and an operativ-e connection between said last mentioned shaft and said auxiliary wheel for shifting said shaft when the wheels are actuated by means carried by a traveling vehicle.

In testimony whereof I affix my signature v in the presence of two witnesses.

, JOHN TOTH.
