PATENT @Ferca SWITCH-RAIL LOCK.

SPECIFICATION forming part of Letters Patent No. 759,756, dated May 10, 1904.

Application tiled Uetober 24,1902. Serial No. 128,524. (No model.)

To atl/L wlw-nt may concern,.-

Beit known that I, ALEXANDER SCHNEIDER,

a citizen of the United States of America, and

a resident of Whitebear, in the county of Ramsey and State of Minnesota, have invented certain new and useful Improvements in Switch-Rail Locks, of which the following is a specification.

My invention relates to improvements in switch-rail locks, and has for its object to provide a simple and effective lock for railroadswitches. This result is produced by a studbolt on the side of one of the switch-rails which projects through an opening in the web of the main rail and a key passing through the outer end of said stud-bolt.

In the accompanying drawings, forming part of this specification, Figure l is a plan view of a section of railroad and switch, the latter shown in open position and provided with my improved lock. Fig. 2 is a crosssection of a main rail and switch-rail in closed position, showing my improved lock. Fig. 3 is a plan view of Fig. 2. Fig. 4L is a detail sectional view of a switch-rail, showing the stud-bolt attached thereto; and Fig. 5 is a perspective view of the key used with .my improved lock.

In the drawings let A and B represent the main rails and C and D the switch-rails, which are of ordinary construction. My improved switch-lock, as shown, is attached to the switch-rail C and consists of the stud-bolt 2, which projects from the side 3 of the switchrail and is threaded at I into its web. The threaded end of the stud-bolt is upset at 5 for the purpose of fastening the stud-bolt securely to the switch-rail. The web 6 of the main rail is provided with the opening at 7 to admit the end of the bolt when the switchrail C is closed, as shown in Figs. 2 and 3. rIhe outer end of the stud-bolt is slotted at 8 to receive the key E, which rests horizontally against the side 9 of the web when the switch is locked. The key E, as shown, is a iiat piece of metal formed with the stop-shoulder at 10 on one end and the perforation 11 on the other end for fastening a padlock 12.

In use I preferably attach the key and lock,

respectively, by means of the chains 13 and 14 to the ties 15 of the railroad, so that the loose parts of the lock will not be lost or carried away. The switch-stand F may be of any ordinary construction and is connected with the switch-rails C and D by means of the switch-rods 16. In operation when the switch is closed the stud-bolt projects through the web 6 of the rail, as shown in Fig. 2. The key E is then inserted through the slot 8 and the padlock 12 fastened, through the perforation 11 of the key. 'I he switch-rails are thus fastened securely in closed position. l/Vhen the switch is opened, the padlock is unlocked and removed, the key E withdrawn, and the switch-stand F operated in the ordinary manner, so as to open the switch-rails C and l) to the full-line position. (Indicated in Fig. l.)

Having described my invention, what I claim as new, and desire to protect by Letters Patent, is-

l. A device of the class set forth, consisting, in combination, of a switch-rail, a studbolt on the side thereof, a main rail having an opening in its web through which said bolt is adapted to project, a perforation in the outer end of said bolt, a key adapted to pass through said perforation and rest against the side of the rail-web to prevent the opening of the switch-rail, and means ior preventingI the removal of said key.

2. A device of the class l`set forth, consisting, in combination, of switch and main rails, a perforation in the web of the main rail, a stud-bolt threaded in the side of the switchrail and adapted to project through said perforation, a key resting horizontally against the side of the rail-web, and a stop-shoulder on said key, for the purposes speciiicd.

A device of the class set forth, consisting of a main rail, a switch-rail, a stud-bolt on the side olf-said switch-rail, an opening in the web of the main rail through which said studbolt is adapted to project, a slot in the outer end of the stud-bolt, a key adapted to pass through said slot and rest horizontally against the web of said rail, and a padlock for fastening said key through said slot.

1I.
