ASSIGNORS TO SAID MARGARET MOCAHILL.

ADJUSTABLE CHANDELIER-HANGER.

SPECIFICATION forming part of Letters Patent No. 255,442, dated March 28, 1882.

Application filed September 14, 1881.

To all whom it may concern:

Beit known that we, MARGARET MCCAHILL and J OHN K. McOAHILL, of Detroit, in the county of Wayne and State of Michigan, have invented an Improvement in Adjustable Ghandelier-Hangers, of which the following is a specification.

The nature of this invention relates to certain new and useful improvements in devices for suspending chandeliers from the ceiling in such manner that such chandelier may be readilyadjusted at desired points between the ceiling and the floor.

The invention consists in the novel construction and arrangement of parts, as more fully hereinafter described.

Figure 1 is a vertical sectional view. of our improvement. Fig. 2is an enlarged sectional elevation. Fig. 3 is a plan of the bottom.

In the accompanying drawings, which form a part of this specification, A represents a tube or pipe, in the top of which is secured the plug B, the upper end of which terminates in a screw, 0, designed to engage with one of the timbers of the ceiling. This tube A is sleeved within a tube, D, and a spring, E, which counteracts the weight of the supporting parts, is inclosed within said tubes and secures them together, as shown, one end of said spring being secured at the top to the tube A, and the lower end being secured at the .bottom to the head of the hollow bottom E, such bottom being screwed or otherwise secured to the lower end of the tube D. This bottom is provided with a handle, F.

H is a bearing secured to and projecting from the tube D near its upper end, and I is a bell-crank lever pivoted to said bearing, and to the upper end or arm of this lever is pivoted the latch or dog J, the free end of which passes through a slot, K, in the tube D to engage with one of the notches, L, a series of which are cut in the side of the tube A, each notch having its lower side inclined in order to allow of the freedownwardmovementofthe dog. A spring, I

above-described engagement, except when the latch is forcibly disengaged by pushing upon the button N, which is secured upon the end of the rod 0.

P represents an oil-chamber surrounding and supported by the bottom E, and from which the lamps R are fed through the tubesS.

As shown in the drawings, the device is adapted to support an oil-lamp chandelier; but it can readily be used for a gasalier by leaving out the screw-plug at the top and screwing the tube A to the service-pipes in the usual manner.

Weareawarethatchandeliershaveheretofore been constructed of two tubes, one sliding within the other and counterbalanced by springs and provided with looking devices, and therefore we do not broadly claim an extensible chandelier provided with a counterbalancingspring and a locking device.

What we claim as our invention is- In a chandelier, the stationary pipe A, provided with notches L, having downwardly-inclined lower sides, the pipe D, sliding on said pipe and provided at one end with the bracket H and atthe otherend with theburner-branches, and the spring E, contained within the two tubes and connected to their opposite ends, in combination with the lever I, connected to the bracket H at one side of the tube and with a spring, M, on the other side, the dog J, pivoted to the upper end of the lever and engaging with notches L, inclined, as described, in the stationary tube, and the rod 0, pivoted to the lever near the center of the same and extending downward close to the side of the pipe D, as and for the purpose specified.
