GEORGE MARTIN KIM, OF ALLEGHENY, PENNSYLVANIA.
ELECTRIC STREET-LIGHT.
SPECIFICATION forming part of Letters Iatent No. 443,097', dated December 23, 1890.
Application tiled May I9, 1890. Serial No. 352,424. (No model.)
To all wwnzit may concern:
Be it known that I, GEORGE MARTIN KIM, a citizen of the United States, residing at Allegheny, in the county ot' Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Yard-Arms for Electric Street-Lights 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 pertams to make and use the same, reference bcing had to the accompanying drawings, which form a part of this specification.
My invention relates to improvements in yard-arms for suspending electric lights from telegraph or other poles, and has for its object to provide a simple and strong support for an electric lamp.
'A further object of my invention is to provide an arm which can be readily lowered for the purpose of replacing the carbon in the lamp, dac., without interfering in any way with tralic on the street over which the lamp is hung.
Vith these and other ends in view my invention consists in the combination of devices and peculiar construction and arrange ment of parts, as will be fully described and claimed hereinafter.
Referring to the accompanying drawings, forming a part of this application, Figure 1 is a perspective View of my improvement applied to a telegraph-pole. Fig. 2 is a detail view of the face-plate which is secured to the pole and to which the yard-arm is suitably connected. Fig. 3 is a detail view of the pivotal braceplate. Fig. a is a detail view of a hook secured to either end of the yard-arm.
Like numerals and letters of reference denote corresponding parts in all the figures,
referring` to which- In this plate 3 is fixed one end of a short shaft 3. On this shaft 3 is fitted a brace-plate 15, which is provided on its upper and lower edges with outwardly-extending flanges A, in which are. formed grooves A through which grooves pass the upper and lower members of the supporting yard'arm. The plate 15 is prevented from slipping off the shaft 3 by a nut The yard-arm proper consists of two arms 6, preferably made of gas-pipe or similar material. These arms pass through the grooves A in the upper and lower faces of the pivoted plate 15, and their outer ends are drawn toward each other and held in place by a strip 16, in the lower end of which is formed a hook 9. To one of the pieces 16, at a point midway between where the two arms 6 pass through said strip, is attached one end of a strengthening-rod S, the other end being connected to a brace 7, situated intermediate of the pole and the end of the yard-arm which carries the lamp, and provided near either end with an aperture through which the members 6 of the yard-arm pass. To one of the hooks 0 is connected one end of a cable or rope 12, the other end of which is attached to a windlass 13, suitably journaled on the pole 1 at any desired height from the ground. From the other hook 0 is suspended the lamp 10, the wires for which pass through the hollow members 6 of the yard-arm.
The operation of my invention will be readily understood from the foregoing description, taken in connection with the drawings. Then the lamp is in position for lighting the street, the several parts occupy the positions illustrated in f ull lines in Fig. 1. When it is desired to lower the lamp for any purpose, the windlass 13 is turned, and by allowing the cable 12 to become slack the Weight of the lamp and arm will cause the same to descend, the plate 15 turning on the shaft 3. By turning the windlass in the opposite direction the lamp and arm are raised to a horizontal position. It is impossible to raise the lamp higher than that shown in full lines in Fig. 1, because when it reaches that position the lower edge of plate l5 rests on the upper face of a seat 5, rigidly attached to the faceplate 2.
Having thus described my invention, what I IOO plate, the transverse brace through which the members of the arm pass, the longitudinal brace-rod extend in from the transverse brace over the pivot of the braeeplate to one end of the arm, and the the stop fixed on the faceplate for limiting` the downward movement, as and for the purpose described.
In testimony that I claim the foregoing I hereunto aflix my signature.
GEORGE MARTIN KIM. In presence of- GEORGE C. GERLACH, l. JOHN NETHEP..
