AUTOIVIATIC SWITCH.

Specication of Letters Patent.

Application iletl September 19,1906. Serial No. 335,221.

tracks the empty cars are usually shunted to the siding by making a iiying switch.

The present invention has for its object to improve and simplify the apparatus dis-I closed in Letters Patent of the United States granted to me July 17, 1906, No. 826,366.

In the accompanying drawing, Figure 1 is a plan view of the switch and its operating mechanism. Figs. 2, 3, L1, and 5 are side elevations showing the parts in diiferent positions. 1

Referring speciiically to the drawings, 10 denotes the rails of the main track, and 11 the rails of the siding. The movable switchrails 12 are carried by the usual switch-bar 13, to one end of which is fastened a switchclosing spring 14. The other end of the switch-bar extends under the outer rail of the main track and beyond said rail, the extremity of the bar being formed with an upstanding iiange 15. Between this flange and t-he last-mentioned rail is a wedge-bar 16 for actuating the switch. The flange 15 carries a friction-'wheel 17, which engages the outer edge of the wedge-bar.

At 18 is indicated a trip-lever, which is located adjacent the outer rail of the main track on the outside thereof. This lever is in the path of the wheels of the locomotive or motor and actuates the wedge-bar, being connected thereto by a rod 19. The trip-lever is in the shape of a link and swings on trunnions 20, extending from its sides and journaled in suitable bearings. The link is made heavier or weighted on one end, so that it will be normally in upright position. The end of the rod 19 next to the trip-lever is formed into a loop 21, through which the top cross-bar 22 of the trip-lever extends, whereby a loose connection is had between said lever and the rod. The object of this loose connection will be explained hereinafter.

The normal position of the parts is as shown in Figs. 1 and 2. In this position the switch is closed and the cross-bar 22 of the trip-lever is at the front end of the loop. If now a train is approaching the switch with the motor or locomotive in front and it is desired to make a flying switch, the motor is uncoupled a short distance in front of the switch and run ahead at increased speed. I/Vhen the motor-wheel strikes the trip-lever 1S, it is swung downwardly to the left, as shown in Fig. 3, whereby the wedge-bar 16 will be pulled forwardly, which opens the switch to enable the cars to run into the siding. After the motor-wheels have passed the trip-lever it swings back to an upright positionm as shown in Fig. 4, its loose connection with the rod 19 permitting this move-k ment. When the trip-lever assumes this last position, the cross-bar 22 will be at the rear end of the loop 21, so that when the niotor is returning on the main track with loaded cars and the motor-wheels strike the trip-lever and swing it to the right, as shown in Fig. 5, the wedge-bar will be pushed back to its original position to close the switch. After the cars have passed the trip-lever it will again come to an upright position, with its cross-bar 22 at the front end of the loop 21. The parts are then restored to their normal position. (Shown in Figs. 1. and 2.)

I claim- 1. The combination with a switch-actuating member, of a car-actuated trip constructed to swing in either direction, means for automatically returning the trip to operative position, and a connection between said trip and member for operating the switch when the trip is swung in either direction, and constructed to allow the return movement of the trip.

2. The combination with a switch-actuating member, of a car-actuated trip constructed to swing in either direction, means for automatically returning the trip to operative position, and a loose connection between said trip and member constructed to operate the switch when the trip is swung in either direction, and to permit the return movement of the trip.

3. The combination with a switch-actuating member, of a normally erect car-actuated trip constructed to swing in either direction, and a connection between said trip IOO IOT
