I, WILLIAM RICHARD CLAY, of 137, Rawson Street, Farnworth, near Bolton, in the
County of Lancaster, Engineer, do hereby declare the nature of this invention to be
as follows, that is to say :-
It relates to improvements in the construction' of gas-burners used in con-
uection with incandescent bodies or mantles which are of a very. fragile nature,
whereby jerky or violent vibrations or movements to which the burners are or may be
subjected when mounted on the usual bearings, are intercepted and so. counteracted
as to prevent them from damaging said mantles, and my said invention consists in
constructing said burners so that the parts of saine upon which the mantles are
mounted are entirely supported and everyway held by resilient bearings and clear of
all guiding pieces or rigid stays.
As is well known the burners used in connection with incandescent-gas-lighting are
so constructed as to produce a "Bunsen's flame" by the adinission of air at a certain
part of it to mix with the gas also fed thereto.
Usually the openings for the admission of this air are made into the tubular part
near or surrounding the gas-supply-pipe, but in accordance with my invention I
now make this gas-supply-pipe of a size less than that in the burner into which it
takes by which means the passage intervening between these two parts of said
burner affords facilities for the admission of the air. The upper part of the burner
which takes over the gas-supply-pipe is carried or supported from the latter by means
of spring or resilient attachments which are also arranged to maintain same in position
in every direction without any part of the former touching or being interfered with
by the said latter. Or these supporting springs or bearings may be secured above the
burner to parts entirely independent of same so that in this case no part whatever of
the portion which carries the mantle is supported or even in contact with the gas-
supply-pipe or other rigid body or fixture.
Provided the opening between the two parts is required to be adjusted or regulated
as to its size relatively with that of the gas-supply-pipe so as to secure the proper
proportions of each, they may be formed of a tapering construction or otherwise so
that by being advanced towards or made to recede from each other by any appropriate
adjusting devices the desired result is attained. The resilient bearing for the upper
part of the burner in accordance with one arrangement may be formed by being
mounted upon a coiled supply-pipe which is secured in position to feed the pilot
light or produce what is known as a "bye-pass" burner as well as support said upper
nart

page_text: The springs employed as the resilient bearings may be either of the spiral form or
those known as "flat spring" or even coiled or other forms of springs may be used by
the several parts being correspondingly shaped to fit or suit them.

Improvements in Incandescent Gas-burners.
I, WILLIAM RICHARD CLAY, of 137, Rawson Street, Farnworth, near Bolton, in the
County of Lancaster, Engineer, do hereby declare the nature of this invention and
in what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement, that is to say :-
My invention relates to improvements in the construction of gas-burners used
in connection with incandescent bodies or mantles for lighting purposes and since
the said mantles are of a very fragile nature it is found that they necessitate the
employment of means to counteract, intercept or divert any or all jerky or violent
vibrations or movements that might be transmitted through the burners and their
bearings to said mantles otherwise considerable loss and inconvenience result from the
breakages or damages thereof. Heretofore the means employed for the purpose of
counteracting the said damaging movements have consisted of resilient bearings
for the burners and their mantles together with flexible pipe couplings for supplying
the gas thereto, or the metal supply-pipe is bent or coiled to afford resilience for
the burner and its mantle, however as these are somewhat unsightly their use has
been to a certain extent avoided so that to obviate this and produce a burner
embodying all the advantages that can be desired of it without the use of flexible or
resilient gas-supply-pipe therefor is the object of this invention.
This object I attain by constructing the burner so that that part of same by
which the mantle is mounted or supported, is entirely carried and everyway held by
resilient bearings and that clear of all guiding pieces or rigid stays. The method of
construction followed for this purpose being hereinafter fully described by reference
to the accompanying sheets of drawings wherein :-
Fig. is a sectional elevation of a burner constructed in accordance with my
invention, the resilient bearings being arranged on the outside thereof as hereinafter
explained.
Fig. 2 is a similar view to Fig. 1 but shows how the size of the air inlet may be
varied or adjusted.
Fig. 3 is an elevation (drawn to a reduced scale) showing the burner so suspended
from or by resilient bearings as it might be within a street lamp, the latter being
shown in broken lines.
Fig. 4 is a similar view to Figs. 1 and 2 but shows the resilient bearings within the
burner's outer part.
Fig. 5 is a sectional plan on line A B of Fig. 4.
Fig. 6 shows a construction of burner similar on the outside to that shown by Fig. 4,
but with the parts within arranged and formed so that additional inlets for the air are
produced.
Fig. 7 shows another form whereby the auxiliary air inlets are produced while the
upper part of the burner is greatly reduced in length.

page_text: Fig. 8 is a sectional elevation showing a style of burner supported by a series
of springs and held laterally by same and another series all of which are desired
to be under tension.
Figs. 9 and 10 are sectional elevation and plan of an arrangement of burners having
their complement of supply pipes and one spring with its several other parts to form
the resilient supports therefor.
Fig. 11 is a sectional elevation showing several burners fed by one supply pipe and
supported by a spring surrounding a certain part of same.
Fig. 12 is part sectional elevation (drawn to a reduced scale) also showing a
method whereby one supply pipe and one spring may be used in connection with
several burners.
Figs. 13 and 14 are front and side views (also drawn to a reduced scale)
showing an arrangement whereby two springs may be used to support several burners
beneath them.
Fig. 15 is a sectional plan of parts shown by Fig.4 but with an alternative arrange-
ment of springs to counteract any lateral vibrations of the burners.
Similar letters and figures of reference indicate similar parts throughout the
several views.
As is well known the burners used in connection with incandescent-gas-lighting
are so constructed as to produce a "Bunsen's" flame by the admission of air at a
certain part of said burner to mix with the gas also fed thereto. The openings
through which this air is admitted to mix with the gas have heretofore been formed
in the tubular part of the burner which leads up to where the gas is burnt in the
Bunsen flame, but in accordance with my invention I entirely separate this tubular
part, such as at a, from the upper part b above it, so that a clear space c is left
between the two by which means the gas supplied through said part a mixes with the
air entering through the open space c, as indicated by the arrows, and rises to be
consumed at the part b¹ to render the mantle d incandescent as desired.
In Fig. 1, for instance, the part b is arranged to be supported by the spring f taking
under its projecting flange b2 and resting upon the annular piece g supported from
the supply pipe a by means of the projections g¹ and pillars g² g3; thus it will be
seen that any vibratory or other movements of the pipe a that are transmitted
to the mantle d, which is supported by the rod d¹ carried by the part b, will
have to pass through the resilient spring f by which it is alone supported and by
which means the desired counteractions are attained.
Instead of the resilient supporting spring being on the outside of the part b
as shown by Fig. 1 it may be arranged to be within it as shown by Figs. 2 and 4 in
which case the converging arms 63 are used in place of the flange 62 while should
the base of the support afforded by said part a be thus brought within too small a
space, the additional vertical springs h (of weak or slight construction) secured
at to the pipe a may be employed to counteract lateral vibrations and give the
parts alignment. Or the arrangement of radiating springs h², shown by Fig. 15,
inay be employed for this purpose.
Again the part b may be supported by a spring f¹ above it as shown by Fig. 3 in
which case its rods k k¹ reach up to said spring which is supported from some-
thing entirely independent of the supply pipe a such as from the top part of an
ordinary street lantern which is shown in broken lines, or such superposed support
may be the roof of a room or building or the like should said burner be used in such
a place or position.
Or again two springs ff as shown by Figs. 13 and 14 may be arranged by
rods m m¹ and arms n n to support several parts and their mantles d. Or a single
burner may have a series of springs f arranged around it as shown by Fig. 8 so that
it may be supported from a corresponding series of pillars 94 while weaker springs h³
slightly extended so as just to be in a state of tension may be arranged to counteract
lateral vibrations or movements.
The arrangement shown by Fig. 9 enables one spring f to support a part 6 having
a number of incandescent parts mounted upon it while a number of supply pipes a

page_text: are employed. Or one supply pipe a may answer for one part 65 upon which a
number of incandescent parts are mounted as shown by Fig. 11, in this case also only
one resilient supporting spring f is employed. Or this arrangement may be reversed
and one supply pipe a may be enlarged and have a number of outlets a² supplying a
like number of separate parts as shown by Fig. 12 and in this case also only one
supporting spring f is employed for the whole series.
The construction of burners, by one part being separate from the other as above
described enables a formation whereby openings for the admission of air for mixing
with the gas may be used in more than in one position as shown at c c² and c³ by
Fig. 6, or at c and ct by Fig. 7. In this latter figure the part b is shown considerably
shorter compared with the sizes of the other parts than it is in the other figures,
which shows that I am perfectly aware that its dimensions in any direction may be
varied to meet the requirements or tastes of the producer or user.
A gauze shield p is employed and arranged to encircle the openings c as shown by
the several figures. By employing an adjustable disc z (see Fig. 2) which on being
rotated upon the screw thread on the pipe a inay be made to advance towards or
recede from the opening c, this said opening may be increased or decreased in capacity
for allowing more or less air to flow to mix with the gas as occasions or circumstances
may necessitate.
In order to make the mantles fit nicely over the upper ends of the parts these
latter are made of a tapering shape somewhat as shown by Figs. 7 and 8 while an
annular flauge s is formed about same to protect the lower edge of the mantle d from
the actions of inrushing air. In Fig. 8 the flange s is shown as being detachable and
formed to carry the rod and its mantle d by which means said parts may be
readily removed from the part b to allow, repairing or cleansing operations to be
carried out..
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is
1. In an incandescent-gas-burner, a mantle, a part by which said mantle is
'supported, resilient supports for holding and retaining said part and a gas supply pipe,
the latter being separate from or not in contact with the former and arranged in
combination substantially as herein specified.
2. In a burner for incandescent-gas-lighting, a mantle, a part upon which said
mantle is mounted, a gas supply pipe and resilient supporting means interposed
between said supply pipe and the part carrying the mantle whereby said part is
retained in position without being in contact with said pipe substantially as herein
specified.
3. In a burner for incandescent-gas-lighting a mantle, a part upon which said
mantle is mounted, a gas supply pipe and resilient supporting and retaining means
interposed between said supply pipe and the part carrying the mantle whereby these
latter are supported and retained by yielding devices and that so as not to be in
contact with any rigidly held part substantially as herein specified.
4. In burners for incandescent-gas-lighting, mantles and parts for supporting
same, a resilient spring for sustaining said parts and their several mantles and a gas-
supply-pipe in combination, the same being arranged so that the latter in no way
interferes with the former except through the resilient connections substantially as
herein specified.
5. In a burner for incandescent-gas-lighting, a mantle, a part, for carrying said
mantle, resilient supports for said part and mantle and a gas supply pipe in
combination the same being constructed so that air is admitted in order to mix with
the gas at two or more positions the whole being combined and arranged as herein
specified.
6. In an incandescent-gas-burner, a mantle, a resiliently supported part carrying
said mantle the latter being formed to allow an annular opening between it and the

page_text: gas-supply-pipe and a disc mounted on said pipe to regulate ingress of air at said
annular opening substantially as herein specified with reference to Fig. 2.
