IMPROVEMENT IN GASALIERS.

Specification forming part of Letters Patent No. 116,359, dated June 27, 1871.

To all whom it may concern:

Be it known that I, JOHN H. SEAMAN, of the city of Brooklyn, county of Kings and State of New York, have invented certain new and useful Improvements in Grasaliers, Pendants, and other similar Fixtures for Burning Gas; and I do hereby declare that the following is a full and correct description thereof, reference being had to the annexed drawing and to the letters of reference thereon.

My invention relates to gasaliers or chandeliers for burning gas, suspended from the ceiling at a fixed elevation; and consists in certain new and useful combinations of mechanism whereby one of the branches is made movable and may be drawn down from the chandelier to serve as a drop-light, the gas-way being preserved by extensible metallic connections.

The first part of my invention consists in combining a movable branch with a sliding rod which passes up into the stem of the chandelier, occupying the axis thereof, but which forms no part of the gas-way, and is cut off from the gas-way of the stem by an internal pipe fitted to receive the guide loosely; said internal pipe also being placed within the stem and cut off from the gasway of the stem at top and bottom by a suitable plug between it and the stem-pipe at each end; the gas-way of the stem being the annulus or space or spaces between the stem-pipe and the inner pipe which receives the slide. My invention further consists in combining, with the stem or gas center and the movable branch, a folding gas-pipe, whereby an extensible metallic connection is made with the gas-way of the movable branch. My invention also consists in the arran gement of a spring pulley and cord in combination with the sliding rod which supports the movable branch, the cord passing down through the internal pipe or guide of the stem when connected with the sliding rod.

Figure 1 of the drawing represents a front view, partly in section, of a chandelier constructed with my improvements, showing the movable branch drawn down to use as a drop'light. Fig. 2 is a side elevation of the same, showing the movable branch in place as one of the branches of the chandelier. Fig. 3 is a view of the upper part of the stem and spring barrel, partly in section. Fig. 4, detached view of the movable branch and sliding rod.

a represents the stem of the chandelier, and b the internal pipe or guide for the sliding rod 0 of the movable branch 01. The internal guide b is preferably made of square pipe to correspond with the square form of the sliding rod 0, which is fitted to play up and down loosely within it. The internal guide-pipes extends through the stem, being of the same length, and both pipes are attached to each other at each end by an annular plug or by solder, which fills up the space at the ends between the inner and outer pipes and leaves the inner pipe open at both ends, in manner as shown, with respect to the upper end, at Fig. 3. The upper end of the stem is screwed into a screw-hole, e, in the lower part of the casting or frame 6 which contains the spring barrel f, the cord f from which passes down through the screw-hole into the internal guide b and connects with the sliding rod of the movable branch. The gas-way of the stem communicates, by side holes in the screw-joint, with a recess, 0 in the screw-hole which connects with the small side pipe g, the latter connecting, by a chamber or passage in the upper part of the frame 0 with the stiff screw-joint g by which the chandelier is connected to the supply-pipe in the ceiling. The lower part of the stem is connected with the cast center-piece h in a similar manner to the upper part, it being screwed into the center and having lateral holes communicating with a recess in the center-piece surrounding the gas-pipe, which recess communicates with the gas-way of the fixed branches, as usual in gas-fixtures. The recess in the center-piece h also communicates with the gas-way of a boss, h, cast or brazed upon the center-piece h, and which connects with the turning joint 11 of the folding pipe 1', the other end of said folding pipe being connected, by aturning joint, is, with the gas-way of the movable branch. The folding pipe j has a folding joint, j, nearly at the middle of its length, and should be provided with a stop, m, to prevent its joints being broughtin line and thereby impede the movement of the movable branch. The usual ornamental part n of the center-piece in chandeliers is detached therefrom and made the medium of connecting the movable branch with the sliding rod, the knob 19 serving as a handle to move the branch up and down. Arecess, w, with inclined sides, is also formed in the center-piece to receive the shoulder q of the movable branch, so that,

when in place, it appears to be a fixed part of the chandelier.

I do not claim as my invention anything described or shown in the patent to Charles Deans, July 19, 1870.

1 claim as my invention and improvement in gasaliers or chandeliers for burning gas-,-

1. In combination with a pendant or chandelier for burning gas, a movable branch in combination with a sliding rod attached thereto, and a stem having an internal guide cutoff from the gas-way, substantially as herein described.

2. In combination with the movable branch,

sliding rod, and a stem with an internal guide cut-ofi' from the gas-Way, the folding gas-pipe, whereby an extensible metallic gas -Way is obtained between the gas center and the movable branch, substantially as described.

3. The arrangement of the spring barrel and cord, in combination with the stem and its internal guide and the siding rod, which supports the movable branch, substantially as described.
