HANGER FoR ELECTRIC LAMPS.

SPECIFICATION forming part of Letters Patent No. 451,149, dated April 28, 1891.

Application filed January 6, 1891. Serial No. 3761838- (No model.)

To all w/tom it may concern.-

Be it known that I, PETER SYLVANUS BATES, a citizen of the United States, residing at York, in the county of York and State of Pennsylvania, have invented certain new and useful Improvements in Hangers for Electric Lamps; and I do hereby declare the following to beafull, clear, and exact description of the invention,such as will enable others skilled 1c in the art to which it appertains to make and use the same.

This invention relates to hangers or supports for electric lamps, and is designed to permit the lamp to be raised and lowered to I any desired elevation in the room as convenience may require.

The invention comprises the fixed casing containing a drum upon which the flexible cord connecting the lampin circuit is wound,

and means for permitting the cord to be Wound and unwound from the drum by taking hold of the lamp itself.

The features of novelty will be hereinafter fully described, and specifically indicated in the appended claims.

. In the drawings illustrating the invention, Figure 1 is a sectional view of the casing, showing the operative parts and the flexible cord at the end of which the lamp is attached.

Fig. 2 is a sectional view taken on a plane at right angles to that indicated in Fig. 1, some of the parts being shown in elevation. Figs. 3 and 4 are detail views of the drum.

Upon a suitable support 1 of insulating ma- 3 5 terial' are secured metallic brackets 2 3, in which is supported a rotatable drum. One journal of this drum is mounted in a bracket I 3, the journal being electrically connected with a metallic strip 4 secured to one head of the drum, but insulated therefrom. Within the drum is a metallic partition 5, provided with a central perforation, in which is journaled a metallic axis 6, the other end of which is squared, as shown at 7, and fits in a square 5 opening in the bracket 2. A spiral spring 8 has one end fastened to the inner periphery of the drum and the other end to the metallic bar, of which the squared end 7 forms apart. A duplex flexible conductor 9 has one of its terminals secured to the metallic strip 4 by 'sulating material.

means of a screw 10, passing through the drum from the outside, as illustrated in the drawings. The other member of the duplex cord has one end fastened to the screw 11, carried by the drum. The lower ends 12 13 of the duplex cord are connected to the lamp terminals. The cord is wound several times about the periphery of the drum, so as to permit the lamp to be raised or lowered to a degree suit able for convenient use wherever located, and is then carried down through an opening in a cap 14, inclosing the parts above described, and secured upon the insulating-support 1.

A roller of insulating material 15 is mounted near the opening. The cord passes through an eye 16, formed in the lower end of an arm 17, forming an extension of the pawl 18, pivoted to the bracket 2. This pawl co-operates with a ratchet-wheel 19, secured to one head of the drum. -Screws 2O 21 are provided for attachment of the device to the ceiling of a room. On a plane at right angles to the screws are metallic clips 22 23 for engaging the service-wires of the system, which supply current to operate the lamp. These clips are held in place by screws 24 25, supporting an insulating-plate 26 of porcelain or other in- A fusible connection 27, which may be a thin lead wire or any other form of cut-out, connects the screw 24 with bracket 2, and another fusible wire connects the screw 25 with bracket 3.

From this description it will be understood that by pulling the lamp supported by the flexible cord the pawl 18 may be withdrawn from engagement with the ratchet-wheel and the drum released, so that the spiral spring can exert its tendency to relax and windup the drum, thus raising the lamp, whereas the lamp-may be lowered by pulling directly upon 9c the lower end of the cord, the pawl then riding over the teeth of the ratchet-wheel and looking it when the lamp has been lowered to y the proper point. I

In connecting the device with the circuit the insulating-support is simply fastened to the ceiling of the room or any other place desired by means of the screws 20 21. The service-wires are laid bare for about a half-inch and inserted in the clips 22 23. When the 1 0 circuit through the lamp is completed, current will then flow, assuming it to enter at the clip 22, through screw 24, fusible cut-out 27, bracket 2, shaft 7, diaphragm 5, screw 10 to one end of the flexible cord, through the lamp, back through the other end of the flexible cord to screw 11,strip 4, bracket 3, fusible cut-out 27, screw 25, and clip 23 to the other side of the main circuit. The cap 14 may be made of any suitable material, but is preferably spun from metal. The porcelain diaphragm 26 prevents the fused wire in case of an excess of current passing from falling upon-Elie drum or cord and interfering with the efficiency of the device. '3

Having thus described my invention, what I claim as new, and desire to secure by Let ters Patent, is p 1. Ahanger for an electriclamp, comprising a rotatable spring-actuated drum, a flexible cord carrying the lamp wound upon the drum, electric connections between the lamp and a supply system, a detent for locking the drum against the tension of its spring in any posipresence of tion of adjustment, and means controlled by the cord for releasing the detent.

2. A hanger for an electric lamp, comprising a rotatable spring-actuated drum, d'uplex connecting-cord 9 wound thereon, ratchet-wheel, pawl co-operating therewith for adjusting the length of the cord, and the arm 17, forming a lever-arm for the pawl and projecting intothe path of the cord. s

3. A hanger for electric lamps, comprising a support, rotatable spring-actuated drum s uspended therefrom, said drum carrying a flexible conducting-cord wound thereon, pawl and ratchet for looking or unlocking the drum, cap 14, admitting a passage of the cord, arm 17 controlling the pawl and controlled in turn by the cord, and roller 15, as and for the purpose described.

In testimony whereof I aifix my signature in two witnesses.
