CAR-LAM P.

SPECIFICATION forming part of Letters Patent No. 367,109, dated July 26, 1887.

Application filed January 9, 1887. Serial No.9.l3,827. (No model.)

To all whom-it may concern:

Be it known that I, JOHN KIRBY, J12, a citizen of the United States, residing at Dayton, in the county of Montgomery and State of Ohio, have invented certain new and useful Improvements in Lamps; and I do hereby declare that the following is a full, clear, and exact description of the invention.

My invention relates to centerlamps for railway-cars and other conveyances; and it consists in a novel manner of constructing such lamps,whereby the common frame, consisting of four and sometimes five pendent hangers, is dispensed with, and one hanger alone is made to rigidly support the lamp and its ad- 3' uncts, as hereinafter more fully described with reference to the accompanying drawings, in which Fignrel is a side elevation of a lamp em- 2 bodying my improvements, and in which onehalf of the supporting-hanger is shown in section, the several parts being shown in their normal or operative positions. Fig. 2 is a horizontal section taken at A A Fig. 3 is a side elevation of a portion of the supportinghanger and coupling-ring. Fig. 4.- is a side elevation of the oil reservoir or fount, and a portion of its branching arms detached from the supporting-hanger. Fig. 5 is a side elevation of another style of lamp embodying my invention,with one of the oil-founts detached and a portion of the hanger shown in section, and

Fig. 6 is a side elevation of the oil-fount detached from Fig. 5.

Similar letters of reference indicate corresponding parts in the several figures.

B, G, and D represent the supporting-hanger, B being an enlarged base for rigid attachment to a roof or ceiling, Ca piece of gas-pipe o screw-threaded at each end, and D an annular cast base for connecting the hanger with any desirable form of coupling for sustaining the reservoir. B and D are provided with screwthreaded collars E F for connection with the pipe 0. I prefer to make the hanger in three parts, as shown in Fig. 1, and cover it with sheet-metal spinnings, asH I, and tubes,asJ J. Kis a collar rigidly attached to and surrounding a portion of hanger O. This collar dispensed with when the supports L L are is provided with arms M Maud shade-supports L L, as more clearly shown in Fig. 2.

N N represent braces for steadying the shades, and are connected with arms lVIM at Z Z. The braces N N and arms M M may be made sufliciently strong to carry the shades and their attachments without vibration. I prefer the construction shown.

O O are domes, such as are common in lamps of this class, and are secured to the outer ends of branch arms L L and braces N N,when the latter are used.

P Pare shades held above the burners in the usual manner.

G, Figs. 1 and 3, represents a coupling-ring of an ordinary car-lamp.

Q, Figs. land 4, is an oil-reservoir provided with branch arms It R and burners S S.

Y, Fig. 1, is a support for the chimney when reservoir is detached, as shown and described in United States Letters Patent- No. 354,910.

T represents an annular ring,'with arms U U extending outwardly, carrying receivers V V and detachable reservoirs W at their outer ends, as shown in Figs. 5 and 6, the annular ring T being secured to the base D of the hanger B O D in the same manner as shown in Fig. l, and thus my improvement is adapted to lamps having one central reservoir and branch arms with burners, as shown in Fig. 1, and also to lamps having branch arms extending from the supporting-hanger with separate reservoirs or founts at their outer ends, as shown in Fig. 5. V

In my improved lamp I obtain a rigid structure, avoid the objectionable form of frame of which such lamps have heretofore been constructed, lessen the cost, and obtain the least possible obstruction to thelight from the burners. V

Having thus fully described my improved lamp, I claim- 1. A hanging canlamp composed of a single supporting-hanger provided at its upper extremity with an enlarged base, as B, in com- 5 bination with a detachable oilreservoir having two or more branch arms and burners, as R R and S S, and domes, as O O, supportedby arms, as L L, extending outwardly from said supportirig-hanger, to which domes shades are attached and securely held above the burners, the whole forminga complete and rigid struet nre, substantially as set forth.

2. Ahanging car-lamp composed of a single supportinghanger provided at its upper extremity with an enlarged base, as B, and at or near its lower extremity with branch arms, as U U, said branch arms being provided with receivers, as V V, at their outer ends, said receivers being adapted to couple with reservoirs, as

l l l l 1 V \V, said supporting-hangerbeing also provided with branch arms, as L L, which carry domes, as O O, at their outer ends, to which 15 domes shades are attached and securely held above the burners, the whole forming a complcte and rigid structure, substantially as set forth.
