ELECTRIC-LAMP POST.
SPECIFICATION forming part of Letters Patent No. 350,046, date-:1 Eeptember 28, 1886.
. \pplicaiion filed June 16, 1385. Serial No. 100,834.
To all whom it may concern:
Be it known that we, HARRY M. DoU'nLn DAY, of New York city, in the county and State of New York, and James LYMAN, of
5 Middlefield, in the State of Connecticut, have invented a certain new and useful Improvement in ElectricLamp Posts, of which the following is a specification.
The object we have in view is to utilize for T supporting incandescing electric lamps, when used for street lighting, the metal lamp-posts heretofore employed for gas, providing means for giving the electric lamps the proper elevation, and for carrying the wires extending i thereto.
The invention is illustrated in the accompanying drawings, in which Figure 11. is an elevation of one ofthe posts; Fig. 2, a similar View with a different wire-support; Fig. 3, a
similar view with a different arrangement of the lamp; Fig. 4, a view of the top of a post with another arrangement of lamp; Fig. 5, an elevation of one form of crossarm with insulators; Fig. 6, an elevation and partial section 2 showing thejointbetween the ordinary lamppost and added parts, and Fig. 7 an elevation of lamp-socket and section of end of supporting-pipe, showing insulatingnipple.
A is the ordinary cast-iron lamp-postas em 0 ployed for gas, having above the arms a a smooth end, I), which is usually slightly tapering. Over this we slip a sleeve, e, having a corresponding taper extending down to arms a. This sleeve is held simply by fric- 5 tion, or it may be fastened by a cross-pin. Upon the upper end of c is screwed a pipe reducing coupling, d, from which rises the lamp and wire supporting extension B. This is a gas-pipe smaller than sleeve 0, as shown.
0 A reversed or downwardly-hanging incandesciug electric lamp, O,with ashade, 1), above it, is supported on a horizontal arm, E. This arm may project from abody or coupling-section in the center of B, as shown in Figs. 1
(No model.)
nipple has a shoulder or collar which separates the socket and end of the pipe and prevents them, from touching. Instead of one lamp-arm, two or more of such arms may project from the same part in different directions radially, and each be provided with the reversed lamp and shade. The upper end oi the extension B has a cross-arm, F. The top of pipe 1) terminates in a- T- coupling, g, and through this extends the wood cross-arm F. It may have a number of insulators mounted on it for carrying the line-wires 1.23, as shown in Fig. 1, the wires 1 and being negative and positive wires, and, the wire 2 being the neutral or compensating wire of a three-wire system; or the cross-arm may be provided with a glass insulator, II, on each end, as shown in Figs. 2, 3, 4, and 5. To the glass insulators It extend from line-wires on neigh boring poles the branch wires 4 5. Thelampwires 6 T extend from the line-wires 1 2 or 2 3, or from the branch wiresat 5,to thelamp-arms, and through them to the lamps. \Vhen the lamp-arms extend from the top of extension B, the lamp-wires will not be exposed, but will extenddirectly through the cross-arm F into the pipe forming the lamp-arm. Fusible safety-catches (represented at i) are placed at thejunction of the lamp-wires with the line or branch wires.
\V h at we claim is 1. The combination, with the post A and upward extensionB, of a pipe lamp-arm, l l, supported by B, and the lamp-comluctors U 7, extending from insulators through the air to the inner end of the lamp-arm, and through such lamp-arm to its outer end, substantially as set forth.

The combination, with post A and upward extension B, of the lamp-arm E, snp- I This specification signed and witnessed this ported from B below the top thereof, a cross- 9th day of June, 1885. j 3 arm for wires at top of B, above lamp-arm, HARRY M.
