Specification of Letters Patent.

Patented June 11, 1907.

Application filed April 10, 1907. Serial No. 367,443.

To (l/ZZ/ whom, it may concern:

Be it known that I, WVILLIAM CARTER, a citizen of the United States, residing at Clinton, in the county of Hickman, State of Kentucky, have invented certain new and useful Improvements in Switch-Stands; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to switch-stands and has for its primary object to provide a switch-stand, the operating mechanism of which may be quickly released and thrown to the desired position to set the switch and display the proper signal.

A further object of the invention is to con siderably simplify the structure of devices of this nature.

The mechanism comprises a cast stand in which is journaled the usual vertically disposed signal shaft and a shaft carrying a crank handle by means of which the latter may be rotated. The two shafts are geared together and a novel form of locking device is provided for the crank handle so that it may be held in position to lock the switch open or closed.

In the accompanying drawings, Figure 1 is a front elevation of the stand, Fig. 2 is a side elevation thereof, Fig. 3 is a top plan view, the signal shaft being broken away, Fig. 4 is a vertical sectional view, Fig. 5 is a similar view but with the hood or casing for the gearing raised, and, Fig. 6 is a detail perspective view of a portion of the stand illustrating in detail the construction of the locking device for the operating handle.

As shown in the drawings, the mechanism comprises a cast stand proper which is indicated in general by the numeral 6 and includes a base 7 for attachment to the ties adj acent the switch to be operated. The stand proper is provided with a vertically extend ing bore 8 in which is journaled the usual vertically disposed signal shaft 9, which shaft is provided at its lower end with the usual crank portion 10 for the connection of the connecting rod which leads to the switch to be operated. At its upper end, the shaft is provided with signal blades or semaphores 1 1 and with a reduced stem portion for the connection therewith of the usual form of signal lamp used in connection with signals of this class.

A beveled gear 12 is keyed or otherwise secured upon the shaft 9 directly above the head of the stand proper and with this gear meshes a similar gear 13 carried by a shaft 14 which is journaled in the head of the stand at right angles to the shaft 9. With the shaft 14 is connected a crank handle 15 by means of which the shaft may be rotated to operate the shaft 9 and set the switch and the signals carried thereby.

Hinged to the head of the stand is a hood or casing 16 which is adapted to cover the gearing above described to protect the same from the elements and this casing is formed with a bifurcation 17 to receive the signal shaft 9, it being understood that the casing may be swung back to expose the gears so that they may be lubricated when necessary.

The switch head is provided with a block extension 18 against opposite ends of which the handle 15 is designed to rest when the switch has been set to either open or closed position and formed upon this block extension at the ends thereof are ears 19 which are apertured as at 20 for the passage of the bail of a lock 21. When the handle is swung to either of its two positions, one of the ears 19 projects through a slot 22 formed therein and the padlock is then applied to lock the handle in this position.

What is claimed is 1. A switch-stand comprising a stand proper, a signal and switch operating shaft journaled vertically in the stand, a gear carried by the shaft, a shaft journaled in the stand at right angles to the signal and switch operating shaft, a gear carried by the last named shaft and meshing with the gear upon the signal and switch operating shaft, a crank handle carried by the second named shaft, a block extension formed upon the stand against which the handle is adapted to rest when at either limit of its movement, the said handles being slotted, and apertured ears formed upon the extension and adapted to project through the slot in the handle, said ears being designed for the connection of a lock therewith.

2. A switch-stand comprising a stand proper, a signal and switch operating shaft journaled vertically in the stand, a gear carried by the shaft, a shaft journaled in the stand at right angles to the signal and switch operating shaft, a gear carried by the last named shaft and meshing with the gear upon the signal and switch operating shaft, a

crank handle carried by the second named lock therewith, and a hinged casing for the i shaft, a block extension formed upon the gears. 10 stand against which the handle is adapted to In testimony whereof, I aflix my signature, rest When at either limit of its movement, the in presence of tWo Witnesses,

said handles being slotted, apertured ears WILLIAM CARTER. formed upon the extension and adapted to Witnesses:

project through the slot in the handle, said JNo. H. SAUNDERS,

ears being designed for the connection of a J. S. DUNNOVENT.
