$PECIFICATION forming part of Letters IlPatent No. 676,792, dated June 18, 1901.

Application filed June 16, 1900. Serial No. 20,563. (No model) T0 60 whom it may concern:

Be it known that I, WALTER EDWARD EM- ERY, a citizen of the United States, and a resident of West Chicago, in the county of Dupage and State of Illinois, have invented a new and Improved Switch-Locking Device, of which the following is a full, clear, and exact description.

The purpose of this invention is to provide effective means for locking switches, and to this end it comprises certain novel devices acting between the main rail and the switchpoint by which the switch-point may be held securely in either open or closed position, as desired. I have here shown the means arranged to lock the switch in open position.

This specification is the disclosure of one form of the invention, while the claims define the actual scope thereof.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indi- Cate corresponding parts in both the views.

Figure l is a side view of the invention,showing the rails in section; and Fig. 2 is a plan view.

or represents the main rail, and b the switchpoint. To the switch point is fastened a bracket 0, which passes outward and downward and is clipped to the switch-rod d. This rod passes under the rail a and is pivoted to the connecting-rod e, which passes to the switch-stand or other operating device.

To the switch-rod d is fastened rigidly an upwardly-projecting stud f,which has a transverse extension f, forming a hasp, and this hasp works with a lock g, carried on an arm it, which extends transversely and is fastened rigidly to the base of the rail a. The lock g may be of any desired form. With this arrangement when the hasp f is entered and fastened into the lock g the switcl1-point b is held in the position indicated by full lines in Fig. l and cannot move until the hasp f is released, and then the parts may be thrown to the position indicated by dotted lines in Fig. 1.

I desire especially to emphasize that the form of the lock employed in this device is not material, nor is it necessary that the lock be rigidly fastened. As here shown it forms a part of the device; but it is clear that an ordinary pad or switch lock could be utilized to hold togetherthe partsf and h. The lock may be applied on either or both sides of the track.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. The combination, with a main rail and a switch point or rail, of a bracket attached thereto,- a switch-rod to which the bracket is connected, a stud carried by the switch-rod and having a part forming a hasp, an arm carried by the main rail, and a lock sustained on the arm and working with the hasp.

2. The combination, with a main rail and a name to this specification in the presence of two subscribing witnesses.

WALTER EDWARD EMERY.
