IMPROVEMENT IN DRCP-LIGHT GASALIERS.
Specification forming part of Letters Patent No. 122,721, dated January 16, 1872.
erence marked thereon making a part of this specication.
This invention has for its object conducting the supply of gas between the outer and inner tube within which the drop-tube works to the stationary branchlights of a drop-light gasalier, either by permitting the gasto tlow directly through the space between said tubes or by forming therein ducts or channels for such purpose.
In the accompanying sheet of drawing', Figure l is a view of my invention in longitudinal section, andFig. 2 a cross-section of same.
Similar letters of reference indicate corresponding parts in the several drawings.
A is the coupling by which the gasalier is attached to the pipe projecting from the ceiling. B is the outer tube ofthe gasalier screwed into the coupling A having small holes or per- G is the inner tube lower end of which the drop-lightF is attached. This drop-tube may be tted with a piston, f, as shown in Fig. 1, or it may be accurately titv ted within the tube B, or any desirable means L may be employed to render it gas-tight and enable it to slide up and downLsuch as stufingboxes, washers, Sto. The inner tube C is itted into the outer tube B in such manner as to afford sufficient space b b between the interior surface of the outer tube and the exterior surface of the inner tube as will allow the gas to flow through the perforation s a a into said space, thence into the branches E E; or, instead of permitting the gas to flow directly through said space and around the inner tube, a series of ducts or tubular channels may be constructed within the said space and thus effect the same object. It will be observed that the gas iowing through theperforations a awill at the same time flow through the drop-tube D to the droplight F.
The chief advantages of conducting gas to the stationary branches of drop-light gasaliers as in my invention are that the expense and weight of additional outside rods or tubing are avoided and at the same time renders the arrangement of gasaliers and drop-light more compact.
I do not wish to confine myself to any particular means of conducting the gasbetween the outer and inner tubes 5 but What I do claim as new, and desire to secure by Letters Patent, is-
A drop-light gasalier, when the gas is conducted to the stationary branches through or by means of a space between the outer tube B
