SWITCH-STAN D.

SPECIFICATION forming part of Letters Patent No. 707,360, dated August 19, 1902.

Application filed March 20, 1902. Serial No- 99,13&. (N0 model.)

To aZZ whom it may concern: Be it known that I, JOHN lSGHRAG, a citizen of the United States, residing at Toledo, county of Lucas, and State of Ohio, have in vented certain new and useful Improvements in Switch-Stands, of which the following is a specification. I

My invention relates to switch-stands.

My object is the provision of a switch-stand having an improved and novel locking device which will be protected against Water and snow and capable of rapid and easy manipulation not only for switching from one track to another permanently, but Where switching operations can be carried on without causing the locking of the mechanisms if'such is not desired. 7

My object is to'provide a switch-stand of the character described which will be adapted to automatically lock when the switch isin proper position, but provided with such novel and improved means that automatic locking will be prevented when desired, so that a series of switching operations can be carried on one after the other as desired without necessitating the locking of the switch and the unlocking thereof after each switch has been thrown.

To accomplish the foregoing objects, I pro-' ing of the lever when locking of the switch is not desired.

The invention comprises certain novel features and combinations of parts, set forth in detail hereinafter and recited in the appended claims.

In the accompanying drawings, Figure 1 is an elevation showing the lever locked and one of the latches closed; Fig. 2, a vertical section of Fig. 1; Fig. 3, a transverse section; Fig. 4, a detail of the locking mechanisms on the lever; Fig. 5, a detail of one of the latches, and Fig. 6 a detail illustrating how the lever is prevented from looking when the latch is closed.

switch-stand,'which may be of any preferred form and provided at its upper portion with a head having the notches 2 for the recep tion of the switching-lever when the latter is down. I

The numeral 3 designates thetarget and lamp-rod, provided atits lower end with the switch-rod crank 4 and at its'upper end with the usual target 5 and lamp 6, said rod extending Vertically through the casing and journaled to turn therein on its longitudinal axis.

Extending out laterally from the casing 1 are the locking members or projections 7 and 8, corresponding to the positions the switchtongue will assume, said projections having the recesses orsockets 9. Pivoted to the cas ing are latches 10, provided with heads 11. The latches are of such construction that they can be thrown up and back against the easing' when it is desired that the switching-lever lock with the locking projection, and the heads 11 are of proper size to fit in the sock ets 9 and completely close the same and themselves to constitute an abutment for the locking-lever to prevent it from passing farther over the locking projection or for the locking mechanisms to engage with the socket,as illustrated in'Fig. 6.

Connected to and extending out laterally from the rod 3 above the casing is an arm 12, and the switching-lever 13 is pivoted thereto at let in such position that when the lever is allowed to drop or is swung downwardly and being in proper position it will enter one of the notches 2, and said lever being also cut out at 13 will pass over the projections 7 or 8.

The numeral 15 designates a locking-bolt pressed by a spring 16, which is located inside a recessed portion 13 and is adapted to spring into cut-out portion 13 and into thesocket 9.

.The bolt 15 has a notch 15 for-"receiving the ward of an ordinary key 18, which can be entered through a keyhole 17 in the lever, whereby the bolt can be retracted. A plate 19 covers and protects the lock and has a lug 20, adapted to engage shoulder 21 on the-bolt and limit the projection thereof by the spring.

The operation of the switch-stand is as follows: The lever 13 is utilized to switch the arm 12 and the rod 3 around to the desired position, and the lever being then allowed to drop or pressed down it willenter in the notch 2, and if the latch is thrown up will pass over the projection 7 or 8, and the bolt will be automatically projected into locking en gagement with the socket 9, whereupon the lever and the switch will be locked. To throw the switch, the key 18 is used to release and retract the bolt, whereupon the lever can be swung outwardly and upwardly and turned and again made to engage with the other projection on the casin g. It frequently happens that it is desired to work the switch back and forth frequently, and in such cases it is obvious that the rapid manipulation of the switch would he hindered if the lever would lock each time the switch was thrown. To provide for this contingency, my improved latches are used. When swung down, with the head thereof entering the socket, the socket is closed, and consequently the bolt of the lever cannot enter said socket and lock the lever; but the lever being forced over the projection abuts against the head of the latch and while looking the switch against being swung open by the passing cars can be readily pulled from the projection and the switch thrown back.

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

1. In a switch-stand, the combination with a frame or casing, of a switching-lever, a device on the frame or casing adapted for en gagement and looking with said lever when the latter is in a predetermined position in relation thereto, and a movable abutment adapted to be positioned in advance of the lever to arrest the movement of said lever and prevent it from assuming said predetermined position.

2. In a switch-stand, the combination with a frame or casing, of a switching-lever, a projecting member on the casing,.provided with a socket, a lock on the lever adapted to engage said socket, and a movable latch on the casing or frame which is adapted to be fitted into the socket and to constitute an abutment to prevent the lever from assuming a position where its lock will engage the socket.

3. In a switch-stand, the combination with a frame or casing, of a switching-lever, a projecting member on the casing, provided with a socket, a lock on the lever adapted to engage said socket, a pivoted latch having a head adapted to be made to fit into the socket and to constitute an abutment for the lever to prevent the latter from assuming a position where its lock will engage the socket.

In testimony whereof I hereunto affix my signature in presence of two witnesses.
