SWlTCH-THROWENG DEVICE.

SPECIFICATION forming part of Letters Patent No. 767,436, dated August 16, 1904.

Application filed November 28, 1903. Serial No. 183,049. (No model.)

To all whmn it may concern.-

Be it known that I, VVILLIAM B. PERRY, a citizen of the United States, residing at right City, in the county of Warren and State of Missouri, have invented certain new and useful Improvements in Switch-Throwing Devices, of which the following is a specification.

This invention relates to improvements in switch-throwing means of the type adapted for throwing the switch either open or closed from moving cars.

The device comprising my invention is especiall y designed for use on motor-cars,though adapted for a general application to any class of rolling-stock.

Particularly the invention consists in a peculiar form of trip-shoe operable by the motorman of the car so as to be thrown into the path of switch-moving devices upon the railroad-track and adapted to be automatically thrown into a normal position out of the path of the track switch-throwing devices after the latter have been operated thereby.

For a full description of the invention and the merits thereof and also to acquire a knowledge of the details of construction of the means for effecting the result reference is to be had to the following description and drawings hereto attached.

IVhile the essential and characteristic features of the invention are susceptible of modification, still the preferred embodiment of the invention is illustrated in the accompanying drawings, in which Figurel is a plan view showing the embodiment of the invention. Fig. 2 is an elevation showing the relative disposal of the switch-throwing mechanism upon a car-track switch-throwing device. Fig. 3' is a vertical sectional view through the support, showing the position of the shoe when out of the path of the track switch-throwing devices. Fig. 4: is a perspective view of the support and shoe separated.

Corresponding and like parts are referred to in the following description and in dicated in all the views of the drawings by the same reference characters.

In the drawings the device is shown applied to the truck of the car, the same being secured thereto in any substantial manner found best in the practical use of the invention. As shown, the shoe 1 is carried by a support 2, adapted to be removably attached to the cartruck 3 at the front end thereof. The structure of the trip and adjacent parts not being essential to the invention no particular description thereof will be given. The shoe 1 is vertically or longitudinally movable relative to the support 2, being normally held within a recess 4, extending from the under side of the support 2. The shoe is supported in its normal position within the recess i by means of a rotatable operating member or bar 5, which is preferably integrally formed with the shoe and which extends upwardly therefrom, passing through an opening 6, leading from the upper side of the support 2 into the recessed portion 4. The member or bar 5 extends through an opening in a movable block 7, being secured to the said block by suitable fastening devices. The block 7 is normally held from the support 2 by means of springs 8, interposed between the block and the support, said springs being of the coil type and being disposed about guide-bars 9, projected from the support and passing through openings formed in the block 7. The springs 8 in their cooperation with the block 7 to hold the same in its uppermost position hold the shoe 1, seated within the recess 4, normally out of the path of the trip devices of the switchtrack.

In order to project the shoe 1 into the path of the switch device of the traclnsuitable means are used, such as a lever or the like, for imparting a longitudinal movement to the operating-bar 5 and to give a rotary movement thereto as soon as the said shoe has been projected from the recess. The operating-bar 5 extends from the shoe at a point between its ends and serves as a pivot means for the shoe, whereby same can be given the rotary movement above described.

The term longitudinal movement above mentioned contemplates a movement substantially in the direction of the axis of the shoe 1, or a vertical movement, in other words. Should the shoe be mounted upon the side of a car or the like, the longitudinal movement by which same would be projected into the path of the track switch-throwing device of course would be a relatively horizontal movement.

In order to lock the shoe projected. from the recess, laterally-disposed recesses are formed upon the under side of the support 2 and upon opposite sides of corresponding ends of the shoe, so that the pivotal movement of the shoe when projected will throw the upper portions of the ends thereof in engagement with the laterally-disposed recessed portions 10. The shoe when thus engaged is held in the path of the trip-throwing devices of the switchtrack, as will be readily seen. The trip-shoe 1 when angularly disposed by the pivotal movement thereof after same has been projected affords an inclined or cam surface in the path of the track switch-throwing devices, which will operate said devices by contact therewith to throw the switch open or closed, as desired by the trainmen. The tensions of the springs 8 when depressed, caused by projecting the shoe 1, serve to hold the shoe firmly in engagement with the recessed portions 10. The shoe is adapted to be angularly adjusted in either direction, so as to permit proper opera-- tion of the switch as the same is moved as the rolling-stock passes thereover.

As premised before in the description, the shoe 1 as soon as the same has cooperated to throw the switch is automatically restored to its normal position seated within the recess. The above operation is effected by contact of the switch-throwing devices in the track with the rear portion of the shoe 1, such contact serving to give the shoe a pivotal movement to throw the same in alinement with the recess a, when the tension of the springs will cause a longitudinal movement of the shoe,throwing the same into its normal position in the said recess L and out of the path of the track switch device. The front portion of the shoe 1 when same projected is rigid. However, the rear portion, as will be understood, is adapted to be moved in the manner above described. The rear portion, above designated, is that portion in rear of the pivotal supporting-bar 5 by which the shoe is operated.

in the operation of the switch-throwing devices the motorman. of the car as the same approaches the switch, if it is desired to operate said switch by actuating the proper means, forces the shoe downwardly, so as to dispose same in a projected position and in the path of the track switch-throwing means. A retary movement given to the operating-bar 5 adjusts the shoe, locking same in its projected position, and as the car reaches the switch the front portion of the shoe striking the track switch-throwing means operates the a same, and as soon as the said track switchthrowing means, which usually is a projection of some character, is operated the said means forces the rear portion of the shoe by a pivotal movement into alinement with the recess a in the support 2, and the said shoe is immediately drawn upwardly under the tension of the springs 8.

Having thus described the invention, what is claimed as new is v 1. A switch-throwing device comprising a longitudinally-movable shoe pivoted at a point between its ends, means for normally holding said shoe out of the path of the track switchthrowing devices, and lock means for holding the shoe projected into the path of the said devices.

2. A switch-throwing device comprising a longitudinally-movable shoe pivoted at a point between its ends, spring means for normally holding said shoe out of the path of the track switch-throwing devices, and lock means for holding the shoe projected into the path of the said devices.

3. In a switch-throwing device, the combination with a support, a shoe provided with front and rear engaging members, and a rotatable pivot member supporting said shoe and disposed intermediate the front and rear engaging members.

In a switch-throwing device, the combination of a longitudinally-movable shoe pivoted between its ends, means for normally holding the shoe out of the path of the track switch-throwing device, means for locking the said shoe in the path of said device, and means for automatically unlocking the shoe to restore same to its normal position.

5. In a switch-tl'rrowing device, the combination with a support, a shoe longitudinally movable upon said support and pivoted between its ends, means for holding the shoe normally out of the path of the track switchthrowing devices, and means engaging the shoe for locking the same projected from the support.

6. In a switch-throwing device, the combination with a support, a shoe comprisingfront and rear alined engaging members, an operating-bar connected to the shoe intermediate the front and rear members aforesaid, and means for imparting a rotary and longitudinal movement to the shoe.

7. In a switch-throwing device, the combination with a support provided with a .recess, a longitudinally-movable shoe seated in said recess, an operating-bar extended from the shoe at a point between its ends, spring means cooperating with the operating-bar to normally hold the shoe within the recess, the under side of the support being provided with laterally-disposed recesses, and means for imparting a longitudinal and pivotal movement In testimony whereof I have affixed my signature ln presence of two wltnesses.
