iSPECIFICATION formingpart of Letters Patent No. 738,637, dated September 8, 1903.

Application filed February 10, 1903. Serial No. 142,727. (No model.)

To all whom it may concern;

7, Be it known thatI, WILBER KNIGHT SMITH, a citizen of the United States, and a resident of Denver, in the county of Arapahoe and State of Colorado, have invented a new and Improved Switch-Operating Device, of which the following is a full, clear, and exact description. a

This invention relates to improvements in devices for shifting switch-tongues for streetrailways, the object being to provide a simple switching device carried by a car and so arranged that byfoot-pressure the motorrnan may cause the shifting of a switch to either .a switch-operating device embodying my in-- vention attached thereto. Fig. 2 is a side Fig. 3 is a detail View illusanism which may be employed, and Fig. 4 is a bottom View of the shifting rollers employed. p

It may be here stated that this device is to be employed in connection with a switch mechanism substantially as shown in my ap plication for patent on railway-switch filed February 11,1903, Serial No. 142,842, and therefore it is not deemed necessary to show the switch in this application.

Referring to the drawings, 1 designates a frame mounted to swing in hangers 2, secured to a plate 3, attached to the front portion of a car-truck, and the frame is held yieldingly in its adjusted position by means of a spring e gattached to the plate 3 and bearing on a portion of the said frame, or the spring maybe arranged to work in any other manner, according to the construction of different makes of cars. Arranged in the frame are rollers 6 7, each roller being provided at one end with an outwardlyextended beveled flange 8, the flange of one roller being at the opposite end to the flange of the other roller. The plate 3 may be a plate or hanger made in different forms to fit on differently-constructed cars. From the frame 1 a rod 9 extends to a connection with a lever 10, pivoted underneath the car-platform. This rod 9 may be short, long, bent, or straight, according to Mount-ed to swing in a bearing 11, attached to the upper side of the car-platform, is a crank-lever 12, the body portion of which extends through an opening in the platform, and the lower crank member 13 passes through a slot 14 in the lever 10. The upper crank portion of the crank-lever, which has its bearing in the part 11, has an angular end 15, on which a treadle 16 is designed to be removably placed. This treadle16 has oppositelyextended arms, each arm being provided with a foot-plate 17, the said foot-plates of course being at opposite sides of the crank. By making the treadle removable it may be shifted from one end of the car to the other end.

The flanges of the rollers 6 7 are normally above the plane of the switch-shifting mechanism. When it is desired to shift the switch in one direction, pressure is to be applied to one of the foot-plates 17, which will rock the lever 10, and consequently cause the rod 9 to tilt the frame to bring one of the flanges 8 into operative position, as indicated by the dotted lines in Fig. 2. Of' course by pressure on the opposite foot-plate the frame will be tilted to bring the flange 8 of the other roller into operative position.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. A'switch-tongue-operating mechanism,

comprising a frame having swinging connection with a car, rollers mounted in the frame having beveled flanges at opposite ends there of, 'oneof said rollers being located forwardly of the other, and the two rollers having unchangeable relation to each other and to the frame, and means operated froma car-platform for tilting said frame to bring either one of said flanges into operative position.

2. A switch-operating device, comprising a frame having swinging connection with. a car, a spring for holding the frame yieldingly in position, rollers mounted in said frame, a bevform, a rod connection between said lever and v the frame, a crank mounted to swing in a bearing on the'car-platform and having connection at its lower end with said lever, and

a treadle for engaging the upper portion of said crank, the said treadle comprising members extended in opposite directions from the crank and foot-plates on the ends of said treadle.

3. A switch-operating device comprising a frame having swinging connection with a ca-rtruck, rollers mounted in said frame, a beveled flange on each roller, the bevels of the two flanges being extended in opposite directions, a lever pivoted underneath the car-platform and having a slot, a rod connection between the lower end of said lever and the said frame, a crank having its lower member engaging in the slot in the lever, and a foottreadle removably connected to the upper portion of said crank.

In testimony whereof I have signed my name to this specification inthe presence of two subscribing witnesses.

WILBER KNIGHT SMITH.
