' Application md september 2s, 1891 serial No. 7531,958. No model.;

To @ZZ whom it may concern.-

Be it known that I, BENJAMIN F. KENT, a citizen of the United States, residing at Eugene, in the county of Lane and State of Oregon, have invented a new and useful Lamp- Bracket, of which the following is a specification.

' This invention relates to lamp-brackets, and is designed for supporting from aceiling or other overhead support gas, oil, or electric lamps.

One object of the invention is to provide a bracket which will readily permit of theadl; justment of the lamp in a horizontal plane as4 well as in a vertical plane, thus enabling the lamp to be carried to different points in the room and to be raised or lowered at the will of the operator.

Further objects and advantages of the in'- vention will appear in the course of the subjoined description.

The invention consists in a lamp-'bracket embodying certain novel features and details of construction and arrangement of" parts, as hereinafter fully described, illustrated in the drawings, and pointed out in the,

claims.

In the accompanying drawings, Figure 1 `is detail vertical longitudinal section through the carrier. Fig. 4 is a sectional view similar to Fig. 1, showing the bracket-armand a hanger of tubular construction. Fig. 5 is a detail vertical section taken through the carrier and a portion of the bracket-arm. Fig.

6 is al section taken on the line mw of Fig.` 5.-

Fig. 7 isa vertical sectional view showing the take-up device arranged above the ceiling or overhead support for the bracket. Fig. 8 is a similar view. showing the carrier mounted on a stationary rail or track for use in` stores or rooms of considerablelength. l w

Similar numerals of reference designate corresponding the drawings.

parts in the several figures of Y The bracket-arm is indicated at 1 and may be either of slotted or tubular construction, as shown, respectively, in Figs. 2 and 4. In Figs. 1 and 2 the bracket-arm is shown as having a longitudinal slot 2, in and along which the conductor 3 for the illuminating agent is adapted to move. The arm 1 is provided at its inner end with a hollow circular hub 4comprising a disk-shaped bottom 4 and a cylindrical iiange 5, extending upward therefrom. Theflange 5 is provided at its upper edge with a horizontally-disposed circumferiential' ange 6 adapted to'engage between .the parallel lips 7 and 8 of a plurality of clips or hangers 9, secured, by means of suitable fasteners, tothe ceiling or other overhead support. The hangers 9 are arranged equidistant from each other, as shown in Fig. 2, and a suicient number of said hangers is employed to enable the flange 6 of the hub 4 to revolve and work freely between the lips l7 and 8 when the arm 1 is swung through a portion of a circle in a horizontal plane.

Mounted to move longitudinally on the arm 1 is a carrier 10, provided with rollers orwheels 11, which` traverse the upper side of the arm.

The carrier is also provided with a horizontal opening or passage A 12, which communicates at its inner end with a vertical passage 13, and near the junction ot' said passages is arranged a pin or axle 14, upon which is journaled a pulley 15, around which the conveyer or conductor 3 passes.

The conveyer or conductor 3 for the illuminating agent may enter the room at any point, as indicated at 16, whencefit passes beneath a pulley 17, having an attached weight 18. The conductor then passes upward over a pulley 19, connected with the overhead su pport, and thence partially around another p ul- `ley 20, connected with the overhead support lcentrally above the hu b 4 of the bracket. .conveyer or conductor Spasses thence down- The `ward under a pulley 21, mounted within the ihollow hub 4, and thence outward through an Aopening 22 in the flange 5 of the hub and ,along the arm 1.

The conveyer 3 passes thence over the pulley 15 of the carrier 10 and ,dwnward through a guide in the form of an zeye'23, projecting laterallyfrom a pendent `hanger or operating-arm 24, connected rigidly {at its upper end to the carrier 10, the lamp IOO (indicated at 25) lbeing suspendedfrom the extremity of the conductor or conveyer 3, as shown in Fig. 1. The weight 18 should be just sufficient to counterbalance the lamp 25j,v so that when the arm 24 is grasped and the carrier 10 moved lengthwise `ot' the bracket-v arm said weight will1 move up and down on the conductor .and take up slack therein at In `this manner the lamp maybe# all times. moved from a pointadjacent to the vertical line of the hub outward in any direction radially therefrornto the extent of the length; yof

be raised and lowered and brought to any desired elevation.l

In cases where a heavy lamp is employed, such as a coal-oil lamp,fwhich would 'bring considerable weight upon the outer end of the bracket-arm, I employ a circular ora-nn-ular track 26, the radius of which is slightly greater than the length of the bracket-arm. This track or rail is supported at required intervals by means of pendent brackets 27, secured to the overhead support, as shown. In connection with the bracket I employ Van antit'riction-roller 28, which is journaled on a stud-shaft 29, projecting outward longitudinally from the extremity of the arm 1. Ity

will thus be seen that the roller 28 may travel freely around the track, which is concentric with the `axis of movement' of the arm, and

the bracket is thus rendered capable of supporting a lamp of considerable weight without bending or breaking the bracket-arm. In case Aa coal-oil -lamp is supported by thev bracket a cord, rope, or chain'will be sub-V stituted for the conductor or conveyer 3, which when it is used to support an electric lamp will consist of the usual ex'rble insu`V lated wire. It will also `be understood that in case a gas lam-p or burner is employed the conveyer 3 will consist of a iexibletube,

through which the gas may pass to the burner; By reference to Figs. 4, 5, and 6 it will be lseen that it is within the scope of this invention to substitute for the slotted arm 1 a tubular arm 30, provided along its under side with a longitudinal slot 31, corresponding with the slot 2 of the arm 1 and fora similar purpose. The carrier 32 in this instance will consist of a sleeve which embraces and slides upon the arm 30 and which is provided with a pendent tubular hanger 33, through which the A pulley 34.,

over the pulley 34, and out of the lower end It is also desirable to apply to the lower end of the hanger 33 a spring hook or clip 37, over and of the hanger 33, as shown at 36.

in which the conveyor 3 may be caught to in-A sure the lamp being retained at the desired elevation,'no matter` to what point the lamp4 may beadjusted in a horizontal plane.

Where there' is a vacantspace above the' overheadsupport or ceiling the conductor 3 `may be carried upward through the ceiling or support, immediately above the hub 4, and the take-up device may be associated there.-

,withrso as toobviate placing the weight 18 Y"and-the pulleys 1'7-an d v'19 within the room.

This arrangement will `be understood with- 1' .outfaddi-tional description and is illustrated :lit may be-desirable tosubstitute forarevolvthe arm 1, and by grasping the lamp or the conductor just above the lamp the latter may" Aing bracket-arm a stationary track or railV 38 "ofany desired length uponwhich the carrier upy slack in the'tlexible support orrcondu'ctor lor conveyer -for thelamp will be j ust' as ef- `ective under` this arrangement as where it iis employed linconnection with a revolving l bracket-arm.
