ADJUSTABLE HANGER FOR INCANDE'SCENT LIGHTS.

- ing drawings.

My invention relates to that class of han'gers for incandescent electric and other lights in which the light or lamp is suspendedfrom a cord which is wound in opposite directions upon a vertically-movable spring-actuated drum, so that-the light may be readilyelevated and lowered or adjusted vertically to any position desired.

The invention consists in the novel construction and combination of parts hereinaf-- ter fully described and claimed.

In the accompanying drawings, Figure 1 is a side elevation of an electric-light hanger constructed in accordance with my invention, partly broken away. Fig. 2 is a side view of the same. Fig. 3 is a vertical sectionalview. Fig. 4 is a detail perspective view of the notched disk and holding dogs or pawls. Fig. 5 is a similar view of one of the rollers with which the Winding-cord engages.

In the said drawings the reference-letter A designates a drum comprising the circular end disks 1 1 and the rim 2, the disks beingof'greaterdiameter than the rim, so as to project beyond the same and form guides for the suspending-cord hereinafter described. Passing loosely through these disks is a spindle 3, provided at one end with a hub 4, securely fixed thereto, and secured to. this hub are two oppositely-extending radial arms 5 and-6, consisting of metal wires or rods, the outer ends bent into a quadrangular loop 4, which are at an angle to the said arms, to one of the arms of which is journaled a grooved roller 8, which are in different vertical planes from the arms.

The numeral 9 designates a disk or collar fixed to the spindle and provided at its periphery with two notches 9*, diametrically opposite Ieach other, with which are-adapted to engage two dogs or pawls 10, which move with the drum when it is rotated on the spinnumeral 12 designates pins or stops secured to said plate which act as stops for the dogs or pawls.

the inner end of which is secured to the spindle 3, while the outer end isattached to a stud 14, secured to the rim of the drum. The nuthe said spindle and located within the drum. This shield is provided with a flaring flange notched disk to prevent interference there with by the coiled spring.

side thereof, is a hook 16, with which engages the suspending-cord 17,whichis wound around the drum in opposite directions,,and a lamp or light secured to its lowerend and its upper end secured to a ceiling or other place or object. 7

The operation is as follows: The suspend the hook on the drum and wound around the latter a number of times and the ends passed through. the loops in the ends of the arms 5 and 6 and bearing against the inner sides of the rollers 8, as seen in Fig. 1. The spindlehub 4 is then held and the drum given a few turns in the direction of the arrow to partially wind the spring, one of the dogs or pawls 1O engaging with the upper notch in the disk 9 to prevent backward or reverse movement of the drum by the tension of the spring. The upper end of the cord is now secured to a ceiling or other place or object, and, the drum being prevented from rotating, the light or lamp will be held against downward movement. Tolower the lamp, it is given a downward pull, which will throw the arms 5 and 6 out of perpendicular by reason of the cord bearing against opposite sides of the rollers, which are in different vertical planes from said arms. This will cause the spindle to 'be'rotated to' the right, which will dle in elevating and lowering the light. The

meral 15 designates a circular shield fixed to- Secured to the rim of the drum, in the out- A The numeral 13 designates a coiled spring at its edge which projects over the pawls and ing-cord is engaged intermediate its ends with throw thepawl or dog out of engagement with the notch of the disk, allowing the rope to unwind from the drum, which will be rotated in the direction of the arrow. So long as the pull uponthe lower end of the cord is sufficient to keep the armsout of perpendicular,

as set forth, the dogs or pawls will ride past the notches without engaging therewith; but when the lamp or light is released the arms 5 and 6 will return to normal position, allowing one of the dogs or pawls to engage with one of the notches of the disk and hold the drum in its adjusted position. To elevate the lamp or light, it is pulled down to release,

the dog from the notch in the disk, as before stated, and then by allowing the cord to slacken a little without releasing the hold on the lamp or light the latter will be elevated.

What I claim is- 1. The combination with the rotatable drum, having a hook on its periphery, and the pivoted dogs and the pins on the inside of one of the heads thereof, of the spindle the notched disk fixed thereto, the hub secured to said spindle, the radial arms secured to said hub having quadrangular loops at the outer ends, the rollers journaled to said loops and lying in different planes from said arms, and the rope engaging with said hook and wound around the drum and its ends passed through said loops and bearing against said rollers, substantially as described.

2. The combination with the rotatable drum hook and wound around the drum and its ends passed through said loops and bearing against said rollers,substantially as described. In testimony that I claim the foregoing I have hereunto set my hand, this 8th day of March, 1895, in the presence of Witnesses. FRED C. BELL. WVitnesses:
