We EDWARD HENRY SWAIN of 1 Summerfield Lake Street Oxford Gas
Engineer's Assistant and GEORGE SMITH of Friars Wharf Oxford Gas Works
Foreman do hereby declare the nature of this invention to be as follows:-
In connection with the use of single coiled springs for counteracting the
damaging effects of vibration upon incandescent mantles, much loss and incon-
venience occurs by reason of the unsteadiness of the burner and consequent
excessive movement during lighting extinguishing cleaning and. the like. Also
that the burner having only one support is liable to have its supply pipe knocked
against its adjacent part. That a single support allows excessive lateral motion,
that sufficient supply of gas for large burners or clusters is not obtained thus
risking an inefficient light. The single springs are not applicable to large burners
or clusters on account of strong support required. That the supply from one
small pipe is liable to be stopped by corrosion or napthalene crystals.
The invention consists of an arrangement of two tees or other suitable fittings
connected by an arrangement of two or more coiled pipes acting as springs. The
fittings may be of iron steel or other metal, and the coiled tubes of copper, brass,
iron, mild steel or other suitable material. The inlet of the lower tee or fitting
is attached to the standpipe of the burner or lamp. The spring tubes are attached
to and supplied with gas from the outlets of the lower tee or fitting and are carried
The coils are in alternate rings and are
up as coils or in other suitable form.
connected in any required position to the second tee or fitting to which the burner
or cluster is attached.
The advantages claimed for this invention are that the weight of the burner
is distributed between two or more points so that greater steadiness in lighting
or moving is obtained, preventing all knocking of adjacent parts near the burner
inlet and all excessive lateral motion or swinging. A second or greater number
of sunnly pipes to the burner are provided thus preventing risk of extinction of
light arising from stoppage or insufficient supply of gas. It is applicable to large

effects.

We EDWARD HENRY SWAIN of 1 Summerfield Lake Street Oxford
Engineer's Assistant and GEORGE SMITH of Friar's Wharf Oxford Gas Works
Foreman, do hereby declare the nature of this invention and in what manner
the same is to be performed, to be particularly described and ascertained in and
by the following statement:
The invention consists of an arrangement of two tees or other suitable fittings 1
connected by an arrangement of two or more bent or coiled pipes of resilient nature
acting as springs for the purposes of support and anti-vibratory effect. The
fittings or tees and the bent or coiled supply tubes may be of iron, brass, copper,
mild steel, or other suitable material. The inlet of one of the tees or fittings is
attached to the standpipe or supply pipe of the burner or lamp, and the spring 2
or resilient tubes are attached to and supplied with gas from the outlets of this
tee or fitting. They are then carried on and at a convenient height are turned
in the shape of coils or other convenient and suitable form. The coils may be
in alternate rings and are connected in any required position to the second tee
or fitting to which the burner or cluster is attached for the purposes of support, 2
and gas supply for lighting or bypass or both. Or the bypass gas may be conveyed
through one of the spring tubes independently of that for the burner or may be
conveyed in any other suitable manner.
Reference being made to the accompanying sheet of drawings in which:―
Fig. 1 shews our improved arrangement of the coiled supply pipes in its
simplest form.
Fig. 2 is similar to Fig. 1, but shews the coils AA, BB connected to the
second tee or fitting D at another convenient height, and another convenient side.
C is the inlet of the tee or fitting which may be attached to the standpipe or
supply pipe. AA and BB are the resilient coiled supply pipes. D is the second a
tee or fitting to which the burner or cluster is attached. AA and BB are
the coiled spiral pipes through which the gas may be conveyed for lighting or
bypass or both.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we are aware of the
Specification of Clay's Patent No. 6,874 of 1896 and we do not claim anything
described and claimed therein, but we declare that what we claim is:
(1) The combination with the parts forming a burner or cluster of burners for
incandescent gas lighting of resilient supply pipes formed of two or more tubes
substantially as herein specified.
(2) The combination with the parts forming a burner or cluster of burners for
incandescent gas lighting of two or more coiled resilient supply pipes for support-
