ELECTRIC-LAMP HANGER.

Specification of Letters Patent.

Patented May 14, 1907.

To all whom it may concern: l

Be it known that I, ADAM SCOTT ELLIOT, a l subjecty of the King of Great Britain, residing at Peterborough, in the Province of Ontario and Dominion of Canada, have invented new and useful Improvements in Electric-Lam Hangers, of which the following is a speci cation.

rlhis invention relates to improvements in electric lamp hangers, the object of the invention being toprovide a simple and effective construction of hanger whereby a lamp may be raised or lowered to any desired position and locked in such position, and whereby danger of conflagration from sparking will be effectually obviated.

In the accompanying drawings,-Figure 1 view of a lamp hanger embodying my invention. Fig. 2 is a longitudinal section of the same. Fig. 3 is an end elevation looking toward the fuse block, with the cover plate thereof removed. Fig. 4 is an inner face view of the fuse block. Fig. 5 is an opposite end elevation from that shown in Fig. 3, showing the drum locking means.

Referring to the drawings, the numeral 1 designates the frame or hanger comprising an attaching bar or plate 2 adapted to be se cured to a wall or ceiling and having depending bracket arms 3 and 4. rIhe arm 3 consists of a continuous strip depending from the portion 2, while the arm 4 is composed of one or more short depending strips 4 and a fuse block or plate 5, constructed and attached to said short strips in the manner hereinafter described.

The bracket arm 3 is provided at its lower end with an angular opening 6 for the reception of the angular end 7 of a shaft or axle 8, on which is revolubly mounted a drum 9. The body of the drum is preferably formed of wood or fiber and is provided with an integral flanged head 10 at one end thereof. The other end of the body of the drum is reduced to fit within the recessed inner face of a block 11 of porcelain or other non-conducting material, which forms the other end head thereof, said block being provided with a circumferential flange 12 having an outwardly turned rim 13. Bolts or other attaching devices 14, having their terminals seated in recesses in the drum body and block, rigidly fasten the same together.

The fuse block 5 is arranged on the outer side of the head 11 and is provided with an inwardly projecting circumferential flange 15 which snugly incloses the iiange and rim of the head, whereby a chamber 16 is formed between saidhead and block. In the fuse block is also formed an opening 17, through which extends the adjacent end of the shaft or axle 8, which is threaded to receive a nut 18. The lower portion of the fuse block is of generally circular form, while the upper portion thereof is provided with straight top and lside edges to give increased area for the attachment of the block to the bracket strips A ange or extension 19 projects from the outer face of the block and forms a chamber 20 adapted to be closed by a cover plate 21 secured in position by the nut 18.

The drum has free revoluble movement on the shaft or axle 8 and is formed in its head 10 with an inner recess 22 in which is arranged a helical spring 23 secured at one end to the axle and at the opposite end to the wall of the recess. The recess is closed at its outer side by a cover plate 24 let into an outer recess 22 formed in the face of the head 10, which cover plate is suitably secured to the head. The outer face of this plate 24 is concaved or recessed for the reception of pivoted gravity pawls 25 adapted to engage a notched clutch head or collar 26 on the axle 8.

The lamp supporting cord 27 has its upper terminals 28 and 29 fastened to binding screws 31 and 32 carried by the head 11 and is adapted to wind upon the body of the drum 9. The screw 31 connects with a commutator plate 33 fastened to the block 11 within the chamber 16, while the screw 32 connects through a stud or screw 33 with a commutator plate 34 which is similarly mounted and arranged. Upon the inner face of the fuse block 5 are arrangedbrushes or contact strips 35 and 36 which respectively engage said commutator lates and are connected by fuses 37 an 38 with binding screws or posts 39 and 40 extending through the fuse block into the chamber 20 and connecting with the circuit wires 41 and 42 entering said chamber through suitable slots or openings in the flange 19. By this construction and arrangement of the circuit connections it will be app arent that the circuit wires will be maintained in constant connection IOO IOS

With the lamp supporting cord 27 at all times during the operation of the drum and that as the cominutator places and brushes are inclosed and supported by parts of non-conducting material all danger of the drum or combustible articles in the room or apartment in Which the lamp is located taking iire from sparking Will be eifectually avoided.

It Will be seen that the shaft or aXle S is held from rotation by its connection with the bracket 3 and is supported by the same and the fuse block 5, and that the drum is free to rotate thereon and by proper manipulation of the cord 27 may be revolved in one direction to let out the cord and in the reverse direction to take up the cord as desired, Whereby the lamp may be supported at any desired elevation, the drum being locked in its adjusted positions by the pawls and locking head 26. Upon removing the cover plate 21 access may be conveniently secured for ad` justmcnt of the binding posts or screws 39 and 40. By detaching the fuse block and cover plate 24 as convenient access may be obtained for repairing or replacing` the circuit connections and spring, Which latter serves to automatically rotate the drum to Wind up the cord, as will be readily understood.

A suitable canopy or ornamental casing may be provided to inclose the drum and parts of the hanger, and rings or loops 43 are provided to retain the cord on the drum and prevent it from jump ing the flanges thereof. These retaining rings inclose or encircle the drum and are suitably attached to the supporting member 2.

Having thus described the invention, what is claimed as new, is l l. In an electric lamp hanger, the combination W11 supporting bracket, of a drum loosely join naled thereon and having a recess at one end and provided at its opposite end with an insulated head 'forming a chamber, closures the recess and chamber, a coiled spring arran l Within the recess and having one end fixed to the drum and the otherr secured to the ait, clutch mechanism associated With th.J closure of the recess and the shaft for holding the drum in any desired position, circuit connections arranged in the chambered head, a lamp suspending cord attached t0 *he drum, and conductors extending through vhe head for electrically connecte ing the Wires of the cord with the inclosed circuit cennii ons.
