JOHN TRIGGE, OF MOUNT VERNON, NEWV YORK.

DROP-LIGHT AND CHANDELlER.

SPECIFICATION forming part of Letters Patent No. 315,976, dated April 14, 1885.

Application filed December 8, 1884. (No model.)

To all whom it may concern:

Be it known that I, JOHN TRIGGE, of Mount Vernon, in the county of .Vestchester and State of New York, have invented a new and Improved DropLight Chandelier, ofv which the following is a full, clear, and exact descript ion.

The object of my invention is to facilitate the adjustment of drop-light chandeliers, and also to prevent the drop-light from sliding down when once adjusted.

The invention consists in a chandelier having an extension or drop-light provided with rack-teeth engaging with cog-wheels in a box on the chandelier, one of the said wheels be ing connected, by an automatic clutching device, with a disk, on which a brake spring or lever rests.

Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure l is a longitudinal elevation of the drop-light mechanism for my improved droplight chandelier, parts being in section. Fig. 2 is a side view of the same. Fig. 3 is a sectional plan view on the line (6 on, Fig. l.

The drop-light burners are held on arms at the lower end of the drop-light tube A, arranged to slide vertically through the box B, held on the fixed tube or pipe of the chandelier. The drop-light tube A is made square or oblong in crosssection, and has rack-teeth a formed in two opposite sides. The teeth on the two sides of the tube A engage with two cog-wheels, O G, mounted loosely on shafts D D in the box B.

On the shaft D a ratchet clutch-disk, E, is loosely mountechand is adapted to engage with another ratchet clutch-disk, F, loosely mounted on the shaft D, and having parts of its rim covered with rubber G, against which the rubber-covered bent end H of a spring or lever, J, rests, which is secured to the box B, and the tension of which spring or lever can be adjusted by a screw, K, passed through the top of the box B.

The tube A is guided by screws at the top and bottom of the box B.

From the clutch-disk E a series of pins, M, project through apertures in the cog-wheel C,

so that the said clutch-disk will be revolved from the said cog-wheel.

Spiral springs N, wound on the pins M between the cog-wheels O and the clutch-disk E, press the clutch-disk E against the clutchdisk F.

The operation is as follows: By pushing the extension or drop-light tube A upward the wheels (3 O are turned in the direction of the arrows a, and the clutch-disk E slides over the clutch-disk F without gripping. Very little resistance is offered to the extension or drop-light tube, and it can be pushed upward very easily. As soon as the said tube is released its weight and the weight of the burners, globes, 830., tend to move it downward, and thereby the wheels 0 O are revolved in the inverse direction of the arrows, and the clutch-disk E is engaged with the clutch-disk F, upon the rim of which the spring J rests, and, acting as a brake, prevents the disk F from turning, and thus also prevents the tube A from moving downward any farther. The drop-light or extension is thus held automatically at any desired elevation.

If sufficient power is exerted, the friction of the spring J on the disk F can be overcome and the drop-light pulled down; but as soon as it is released it isheld in place automatically.

By means of the screw K the pressure of the spring J On the disk F can be regulated.

The above-described device can be applied on drop-light or vertical extension-chandeliers of all kinds for gas, oil, candles, or electric lights.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a chandelier, the combination, with a box held on the fixed tube, of an extension or drop-light tube having racks, cogwheels mounted in the box and engaging with the racks on the extension-tube, a clutching device connected with one wheel, and a retarding spring or lever resting on a pulley or disk connected with the clutching device, substantially as herein shown and described.

2. In a chandelier, the combination, with a box held on a fixed tube, of an extension or drop -light tube having racks, cog-wheels 4. In a chandelier, the combination, with the box B, of the rack-tube A, the cog-wheels G O, the clutch-disks E F, the pins M, the I 5 springs N, and the retarding-lever J, acting on the disk F, substantially as herein shown and described.

JOHN TRIGGE.
