RAILWAY-SWITCH.

SPECIFICATION forming part of Letters Patent No; 778,397, dated December 27, 1904.

Application filed March 17,1904. Serial No. 198,531. i

To all whom it may concern:

Be it known that I, FRANK BAYLEYSS, a citizen of the United States, residing at Spring field, in the county of Clark and State of Ohio, have invented certain new and useful Improve ments in Railway-Switches, of which the fol lowing is a specification.

My invention relates to improvements in railway-switches, and it particularly relates to improvements upon the switch set forth in my Patent No. 7 50,334, issued January 26, 1904. r

The object of my invention is to provide means for looking or holding the movable rails into the position to which they have been moved by the train-operated devices of the switch, so as to prevent displacement thereof by a passing train after the rails have been thrown to closed position by said train in the manner set forth in my said former patent.

A further object of my invention is to provide means to prevent the rebound of the movable switch-point from the main rail which might result from the shock incidental to its operation, and, further, to provide means to force the said switch-point back to its position against the rail in case of any such re bounding or to force the point up against the rail in the event the operating devices should not properly do so.

My invention consists in the constructions and combinations of parts hereinafter described, and set forth in the claims.

' In the accompanying drawings, Figure 1 is a perspective view of a switch to which my invention has been applied. Fig. 2 is a bottom plan View of my device, showing the parts in their operated position. Fig. '3 is a device showing the parts in their normal position.

Fig. 4 is adetail showing the position of the parts after they have been operated. Fig. 5 is a detail showing in full linesthe device in a partly-operated position and in dotted lines the parts in normal and fully-operated positions, respectively. Fig. 6 is a detail of the stationary guide for the device, and Fig. 7 a view of one of the washers for the spring. Fig. 8 is a bottom plan-view showing the parts in their normal or inoperative position.

Like parts are represented by similar letters 5 O are connected together by a bar a to which bar is attached the box or casing 0. Extended through the casing and adapted to be normally connected thereto by spring-pressed plates 0 is the ordinary hand switch-bar 0, connected to a hand-switch 0 for the purpose of operating the switch-rails in the usual way. Also extended through the frame or casing 0 is a train-operated bar 01, connected to train-operated devices 6 for the purpose of operating said bar and in turn the switch-rails under certain conditions. This bar d is formed tapering at a point within the casing or frame 0, as shown at d so as when operated to contact with the spring-pressed'plates, and thus unlock the hand-operated switch-bar from the switchrails, and is also provided with a shoulder d near the point where it passes through the frame or casing, which shoulder will contact with the said frame or casing and move the same in the direction in which said bar 0? has been operated, so as to throw the switch-rails. In Fig. 2 I have shown aspring d placed around the bar (2, between the shoulder and the side of the frame or casing, to obviate any undue jar on the parts at this point. The train-operated bar is adapted to be operated by the said train-operated devices 6 in the manner described in my said former patent, so that in the event of a train approaching a switch I which has been left open suitable contacting devices may be set on said approaching train to operate the said train-operated bar to close the switch.

In order that one of the switch-points or movable rails when operated'iby the train-operated devices shall be moved and firmly held close against the main rail to obviate any danger of disrailment, I have provided the following-described devices: Pivotally connected at (Z to the train-operated bar (Z or to an extension (Z thereof, as shown in the drawings, is an L- shaped arm f, one portion of which is provided witha slot f, through which is extended the upturned end f 2 of a stationary guidefiwhich is secured to the under side of one of the ties. To the inner end of the slotted portion of the arm f is a collar f, and loose on said slot ted portion is a washer f adapted to fit against the upturned end of the stationary guide f Around the slotted portion of the arm f and between the collar and washer is placed a coil-spring f. When the mechanism of the switch is in its normal condition, the parts of the locking device are in the position shown in Fig. 3, with the spring extended. When the train-operated bar (Z is operated by an approaching train to throw the switch-rails to their closed position, the movement of said bar will throw the devices to the position shown in Fig. 4, placing the spring under tension and causing it to exert an influence in the direction in which said bar d has been moved, and thus, by reason of the connection of said bar with the movable or switch rails, through the medium of its shoulder and the casing or frame, as described, exerting a pressure upon the said switch-rails tending to hold them in their operated position. As shown in Fig. 5, the point at which the spring is under the greatest tension is when the parts have completed about half their movement. After the parts have been fully operated it will be seen that before they can again be restored to normal position the spring must be placed under greater tension up to a certain point. Thus any tendency to jar the rails from their position will be resisted by increasing tension of the spring. The parts can be restored to normal position by pulling back the bar d by means of said train-operated devices.

While I have described my invention as relating particularly to the form of switch set forth in my former patent, it is obvious that the invention might be applied to a switch of somewhat different construction, and I do not limit myself, therefore, in its application to the exact devices shown and described.

Having thus described my invention, I claim 1.
