IMPROVEMENT IN EXTENSION-CHANDELIERS..

Specification forming part of Letters Patent No. 222,771, dated December 2?,1879; application filed March 25, 1879.

To all whom it may concern:

Be it known that we, PARTRICK J. CLARK and J OSEPH Krnrz, of West Meriden, in the county of New Haven and State of Connecticut, have invented a new and useful Improve ment in Extension-Chandeliers, of which the following is a specification.

Our invention relates to chandeliers that are fitted with telescopic joints, whereby the lower portion, carrying the burners, may be raised and lowered on a fixed rod attached to the ceiling.

The invention consists in certain novel features of construction and arrangement, whereby the chandelier is rendered compact and the movable parts are sustained securely in position when adjusted.

In the accompanying drawings, Figure 1 is a sectional elevation of our improved chandelier. Fig. 2 is a similar view at right angles to Fig. 1. Fig. 3 is a cross-section on linear w of Fig. 1.

Similar letters of reference indicate corre-- sponding parts.

The rod or tube A is adapted for hanging from a ceiling, or for rigid attachment in any usual manner, and carries the telescopically sliding tube B, to the lower end of which is connected the center-piece 0 of the chaudelier.

The branches or arms for supporting the burners are not shown, and may be attached upon tube B or piece G in any usual manner.

The tube B and its attached parts are suspended by a chain, band, or cord, at, that is connected to the lower end of A and passed around a spring-barrel, D, which is sustained in hearings in a center-piece, (l.

The end of cord a is connected securely to D, and an intermediate friction-roller, 1), prevent-s friction of the cord or chain against the lower end of the tube.

The barrel D is sustained in any desired manner, and contains one or more coiled springs, c, that tend to wind the cord aon the barrel, and thus raise the chandelier. The

spring should be sufficiently strong to raise the parts easily.

Upon the barrel D are cogged flangesd, and fitted to slide vertically in the lower pendantof the chandelier is a rod or pin, 6, the upper forked end of which is caused by a coiled spring, f, to engage with the notches in flanges dd, and therebyprevent the barrel from turning.

The lower end of c is curved or bent outward through .the side of the pendant, and is formed with a finger-knob.

By pressing upon the knob of 0 its upper end is disengaged from the teeth on the drum,

' and the chandelier may then be drawn down,

and the pin or stop released to hold it at the desired place or, by releasing the pin or stop, as described, the spring is permitted to act and raise the chandelier.

The described construction is simple, compact, durable, and .eflicient for the purposes intended.

The chandelier is easily manipulated, and l the weight of the suspended parts is not sustained by balancing, but by a positive stop that may be applied at any point in the range of movement.

We are aware that a chandelier has been supported in any position into which it has been adjusted by the tension of a spring inclosed in adrum, the said spring being wound up by the unwinding of the cord, which is first secured to a rod sliding in a tube, then passed over a small pulley and secured to a shaft whose ends are provided with gearwheels which mesh with a gear-wheel on the bottom of the drum.

We are also aware that a spring-shaft con= nected by a cord to a tube sliding within another tube, and provided with a gear-wheel which is engaged by a detent of a spring-op erated lever to hold the chandelier in any desired position,is old; and we are also aware that a screw-rod which passes through acorrespondingly-grooved plate at the bottom of a tube, and provided with a notched disk engaged by a spring-catch to hold the chandelier in any desired position, is likewise old;

and we therefore do not claim, broadly, a.

chandelier capable of being raised pr lowered;

but

FFIGE.

What we claim, and desire to secure by Letpiece 0, substantially as and for the purpose ters Patent, is-- set forth;

The combination of the rod A, the rope or PARTRIOK J. CLARK. chain a, the roller 2), the flanged drum D, pro- JOSEPH KIN TZ. vided with teeth d on the said flanges, the Witnesses:

spring 0, the forked pin or stop 0, and the WILBUR F. DAVIS, coiled spring f, with the tube 13 and center- I CHARLES E. GOODRICH.
