the Commissioners of Patents, with his Petition, on the 6th March
1871.
I, JOHN HORTON, of No. 620, Broadway, New York, in the United
States of America, but at present residing at No. 113, Hagley Road,
Edgbaston, in the County of Warwick, Manufacturer, do hereby declare
the nature of the nature of the said Invention for "IMPROVEMENTS IN
GASELIERS, SLIDING GAS PENDANTS, AND SLIDING GAS BRACKETS," to be as
follows:
-
My Invention consists in constructing and arranging the parts of the
said gaseliers, gas pendants, and gas brackets in the following manner :—
My improvements in gaseliers consist in combining a central light
capable of being raised and lowered with a series of two or more fixed
lights.
In constructing a gaselier according to my Invention I support the
radial arms or branches of the fixed lights from a tubular body, the said
tubular body being connected with the ceiling plate in the ordinary way.
The gas is supplied to the arms or branches of the said fixed lights by
passing down the said tubular body. I support below and in the centre

page_text: of the arins or branches of the fixed lights a sliding or moveable light,
whereby the said sliding light when required may be depressed from or
raised to the fixed lights without affecting the other parts of the gaselier.
The sliding central light is carried by a gas supply pipe sliding in the
body of the gasolier, and is suspended by means of chains and a counter-
balance weight or weights. I prefer to use a contral balance weight
sliding on the exterior of the tubular body of the gaselier. I either use
with the said sliding central light a water slide of the ordinary kind or
a gas joint or packing in the tubular body of the gaselier to prevent the
escape of gas. I prefer, however, to use a gas joint or packing for that
purpose, the parts of which are arranged as follows:-Within the tubular
body of the gaselier carrying the arms or branches of the fixed lights arc
two concentric tubes, the larger of the two tubes fitting the interior
of the tubular body. In the said larger tube two discs or washers of
leather or other packing material are fixed a short distance apart, the
said washers or packings being secured in their places by screw caps or
plugs. Between the washers or packings described and in the axis of
the larger tube in which they are fixed is a smaller tube, the said smaller
tube having a longitudinal slot cut in it, in which slot the washers or
packings are embedded. The rotation of the said washers within the
larger tube is thereby prevented. The inner smaller tube is filled with
beeswax or other like material. An axial hole is made in the washers
or packings described, and also in their screw caps or plugs, through
which hole and the chamber containing the beeswax the gas pipe of the
central sliding light works, the upper end of the said gas pipe being in
communication with the gas supply at the upper part of the tubular
body of the gaselier. As the central light is raised or depressed its
supply pipe works through the gas-tight joint or packing described, and
the escape of gas is thereby prevented.
My improvements in sliding gas pendants and sliding gas brackets
consist in applying to the said gas pendants and gas brackets a gas-light
joint or packing of the kind herein-before described with reference to the
central light of a gasclier.
