APPARATUS FOR SUSPENDING ELECTRIC LIGHTS.

SPECIFICATION forming part of Letters Patent No. 338,920, dated March 30, 1886.

Application filed September 14, 1885. Serial No. 176,986. (No model.)

To all whom it may concern.-

Be it known that I, THOMAS H. BRADY, a citizen of the United States, residing at New Britain, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Apparatus for Suspending Electric Lights, of which the following is a specification.

My invention relates to means for suspending electric lights over the roadway from a pole by the road-side; and the objects of my improvements are to provide a simple and cheap apparatus for so doing. which shall be simple and easy to operate and will work as well in cold icy weather as at other times.

In the accompanying drawing, the only figure shows my apparatus partly in vertical section and partly in side elevation.

A designates the pole having a cap-iron, 13, secured to the upper end. To this cap-iron there is rigidly attached a cross-beam, C, the lower member of which is in the form of a hollow bar or pipe, to. At each end of the oross-beam C is a pulley, b, the top of which is directly opposite the horizontal passage through the pipe a. These pulleys are covered over by a hood, 0, to protect them from the weather. At the middle portion of the pole there is a Windlass, D,which is provided with means for locking its drum against rotationas, for instance, a series ofholes and a pin, d. To the drum of this Windlass I secure one end of a cord or chain, preferably in the form of a wire cable, f, which cable extends first over the pulley Z1, then through the pipe at of the horizontal cross-heam C, then over the other pulley, b, when its end is secured to a proper bail, g, from which is suspended the electric lamp E. The bail g is provided with an eye, h, for convenience of attaching the ca- 0 ble f, and to said eye (or other connection near it) I secure one end of the guide k. The opposite end of said guide is hung to the capiron B, near the inside corner of the angle formed by the cross-arm and pole. In case the guide is made of a rigid material-as, for instance, a rod-both ends are secured by a hinged or jointed connection, so that it can swing freely thereon.

The lamp is shown in full lines as suspended in position for use.

\Vhen desired to trim the lamp or to reach it for any purpose, the pin d is withdrawn and the lamp let down by unwinding the cable f from the Windlass. In thus letting down the lamp the guide It will pull it toward the pole, instead of letting the lamp straight down, thereby causing it to swing in the arc of a circle into a position by the side of the pole and near the Windlass, as indicated by the broken lines.

I claim as my invention An apparatus for suspending electriclamps, consisting of the pole or upright, the crosshead rigidly attached to the upper ends thereof, the pulleys at the ends of said cross-head, the Windlass attached to the body of the pole, the cable or chain leading from the Windlass through the horizontal passage, through the cross-head,and over the pulleys, and the guide It, for drawing the lamp toward the pole in its descent, substantially as described, and for the purpose specified.

THOMAS H. BRADY.
