LEWIS M. CURRY, OF JACKSON, MICHIGAN, ASSIGNOR OF ONE-HALF TO OSWALD F. JORDAN, OF SAME PLACE.

SWITCH-STAND.

SPECIFICATION forming part of Letters Patent No. 315,011 dated April 7, 1885.

Application filed February 16, 1884. (No model.)

To all whom it may concern:

Be it known that I, LEWIS M. CURRY, a citizen of the United States, residing at Jackson, county of Jackson, State of Michigan, have invented a new and useful Switch-Stand, of which the following is a specification.

My invention has for its object certain inr provenients in such devices to increase their utility and insure greater safety.

In the accompanying drawings forming a part of this specification, Figure 1 is a side elevation with parts broken away and thedraw-bar detached; Fig. 2, a top and sectional view looking down from line 2 2 in Fig. 1; Fig. 3, a broken portion of Fig. l in vertical section on line 1 1 in Fig. 2,- Fig. 4,, a side elevation of a part of Fig. 1, showing the side opposite to that in said figure; Fig. 5, same as Fig. 2,with parts removed; Fig. 6, a plan of a switch and a section on line 3 3 in Fig. 1; and Fig. 7 an enlarged perspective of a part Fig. 6.

The leaning standards B of the stand are provided with a base-plate, D,and a top plate,- a. The top plate has a central hole, 6, in which the round hearing or axle c of the ro tatable carriage c is located.

Through a square hole in the carriage and its axle c the perpendicular signal-shaft P is located.

a u are notches to receive the pivoted lever r, as in other switclrstands. In addition to this mode of locking,which is deemed unsafe,

I have provided the carriage c with a verti-- cally-falling pin-lock, f,adapted to enter holes or in the top plate, Figs. 5 and 3. WVith this construction the pin f and lever r are raised, as in Fig. 4, and the carriage and signal shaft are turnedto the desired position, when the lock-pin will fall by its own weight to the position shown in Fig. 3. The lower part of the lock-pinf is enlarged, forming a shoulder at the top of said enlarged portion adapted to intercept the upper end of the recess d, and prevent the lock-pin from being drawn out when raising it.

The carriage is provided with afiange, e,to cover the lock-holes w. t tare stops to limit the movement of the carriage.

The upper portion of the shaft P is provided with the usual day and night signals, A and L. The lower end of the standard P terminates in a crank, 3

The base-plate D is provided with a notch' or recess, o, beneath the ends of the crank y when said crank is in the position shown in Fig. 6. draw-bar h, which is perforated for the pur pose,can be inserted in the recess 11 and slipped over the end 8 of the crank. The draw-bar at this time is in the position shown by the broken bar h in dotted lines in Fig. 6. By

By this means the end of the switch v connection of the top of the stand is had with said shaft, and the base of the standards does not conflict with the operating means connected with the lower end of the vertical shaft P. (See Figs. 6 and 1.)

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

1. The stand having the upper plate provided with the lock-holes,in combination with a carriage adapted to rotate, and provided with a lock-pin and with a base-flange adapted to cover said lock-holes, substantially as described.

2. The combination,in a switch-stand,of the plate provided with the lock-holes, the carriage provided with the-lock-pin recess, and a lock-pin having the shoulders adapted as set forth, substantially as described.

In testimony of the foregoing I have hereunto subscribed my name in the presence of two witnesses.
