.GASALIER.

SPECIFICATION forming part of Reissued Letters Patent No. 10,071, dated April 4, 1882.

' original No. 116,359, dated June er,

To all whom it may concern:

Be it known that I, JOHN II. SEAMAN, a citizen of the United States,ofBrooklyn, E. D., in the /county of Kings and State ot' New York, have invented certain new and useful Improvements in Gasaliers; and I do hereby declare the following is a full, clear, and eX- act description of the'invention, that will enA able others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

My invention relates to gasalicrs or chandeliers for burning gas, suspended from the ceiling at a fixed elevation; and itconsistsin certain new and useful combinations of mechanisms, whereby one of the branches is made movable and may be drawn down from the chandelier to serve as a drop-ligh t, the gas way being preserved by'extensible metallic connections.

The iirst part of my invention consists in combining a movable branch with a sliding rod which passes up into the stem of the chan delier, occupying the axis thereof, but which forms no part ot' the gasway, and is cut oft' from the gasway of the stem by an internal pipe fitted to receive the guide loosely, said internal pipe also being placed within the stem and cut oli' from the gasway of the stem at top and bottom by a suitable plug between it at each end, the gasway ot' 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 gasway ofthe movable branch.

My invention further consists ,in a novel coin bination and arrangement of a stationary tube-section, a` sliding burner-support, and a.

spring cord-win ding mechanism, the cord passing down through the stationary tube-section, and a guiding-pulley which directs the cord within the tube.

Figure l ot' the drawings represents a front view, partly in section, of a chandelier constructed with my improvements, showing the 1871. Application for reissue filed February 18, 1882.

movable branch drawn down to use as 'a droplight. Fig. 2 is a side elevation ot the same, showing the movable branch in place as one ofthe branches ofthe chandelier. Fig. 3 is a view of the upper part ot' the stem and springbarrel, partly in section; Fig. 4, a detached view ofthe movable branch and sliding rod.

a represents the stem ot'the chandelier, and b the internal pipe or guide for the sliding rod c ot' the movable branch d. Theinternalguide, b, is preferably made of square pipe, to correspond with the square form ofthe sliding rod c, which is tted to play up and down loosely within it. The internalguide-pipe, b, 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 thel 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 ascrewhole, e, in the lower part of the casting or frame e', which contains the springbarrel f, the cord ff from which passes down through the screw-hole into the internal guide, b, and connects with the sliding rod ofthe movable branch. The gasway of the stem communicates by side holes in the screw-joint with a recess, e2, in the screw-hole, which connects with the small side pipe, g, the latter connecting by a chamber or passage in the upper part ot the frame e with the stiE screw-joint g', by vwhich 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, it being screwed into the center and having lateral holes communieating with a recess in the center piece surrounding the gas-pipe, which recess communicates with the gasway of the ixed branches, as usual in gas-fixtures. The recess in the center piece, 7L k, also communicates with the gasway of a boss, h', cast or, brazed upon the center piece, It, and which connects with/the turningjoint i ot' the folding pipej, the other end of said folding pipe being connected by a turning joint, k, with the gasway ofthe movable branch. 'lhe folding pipej has a folding joint, j', nearly at the middle otits length, and should he provided with a stop,m, to prevent IOO its joints being brought in line, thereby impeding the movement of the movable branch.

The usual ornamental part, n, of the center piece in made the mediuln of connecting the movable branch with the sliding rod, the knobp serving as a handle to move the branch up and down. A recess, w, with inclined sides, is also formed in the center piece to receive the sh oulder q of the movable branch, so that When in place it appears to be a fixed part ot' the cliandelier.

By an examination of the drawings it will be readily understood the sliding rod c, the ornamental part n, and shoulder q constitute a support for the rising and falling branch pipe d and the burner, and that by means ot' the ratchet-Wheel o and pawl u, the ratchetwheel being attached to the shaft ot the springbarrel, the tension of the spring may be so regulated as to effect the 'desired suspension of the burner-support.

It will also be seen that the pulley a serves to guide the cord from the spring-barrel to a proper position within the tube-section.

Ido not claim as my inventionr the invention secured in the patentto Charles Deans of July 19,1870.

I claim as my inventiony 1. In a chandelier, the combination of a stationary tube-section, a burner-supportadapted to slide relatively thereto and arranged to always overlap the same, a spring-barrel, a cord Whichpasses through the stationary tube-sec'- chandeliers is detached therefrom andl tion and connects the spring'barrel with the burner-support, and a guiding-pulley adapted to direct the cord from the spring-barrel to the tube-section, substantially as set forth.

2. In a chandelier, the combination, with the stationary tube-section, the sliding burner-support, the spring-barrel, and cord, of a ratchet and pawl arranged, substantially as set forth,l

to hold the springat different tensions and to permit the tension thereof to be adjusted independently of the burner-support.

3. In combination with a pendant or chandelier for burning gas, a movable branch pipe, a sliding guide-rod attached to said movable pipe, and a stationary stem having an internal guideway for said rod cut oifrom the gasu way, substantially as set forth.

4. ,In combination with the movable branch, sliding rod, and a stem with aninternal guide cut off from the gasway, the folding gas-pipe, whereby an extensible metallic gasway is obtained between the gas center and the movable branch, substantially as described.

5. The spring-barrel and cord, arranged substantially as shown, in combination with the stem, the guideway within the stem, and the sliding rod which supports the movable part of the chandelier.

In testimony whereof I aix my signature in presence of two witnesses.-

JOI-IN H. SEAMAN.
