PROVISIONAL SPECIFICATION
Improvements in or appertaining to Burners for use in Incandescent-
gas-lighting.
I, WILLIAM RICHARD CLAY, of 1, Slater 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:-
In connection with incandescent-gas-lighting
much inconvenience and
loss is experienced and entailed by reason of the excessive delicacy or
brittleness of the incandescent substances or articles produced out of them for
which reason street or like public lighting by these incandescent means has
heretofore been attended with the greatest difficulties since often the vibrations
of the burner by a passing vehicle have been sufficient to completely destroy the
useful properties of the incandescent article causing it to break away in pieces or
even to tall to dust. Further, as is well known, the loose edges of the incandescent
articles which are in an ordinary way entirely exposed to the fiction of the
currents of air flowing to support combustion, iapidly deteriorate and portions of
them are broken off long prior to the other parts of said articles being worn out.
To obviate these difficulties by the application of means for counteracting or
otherwise changing the nature of the vibratory motions of the burners as well as
by the application of means for protecting the loose edges of the incandescent
articles, is the object of this invention, and in accordance therewith to counteract
the vibratory motions of the burners arrange the supply pipes for conducting
the gas to them, so that they may be of an appropriately coiled or spiral form by
which they are made to have considerable resilience thus the burners they support
are protected against the damaging effects of the vibratory movement of adjoining
bodies since all such movements have to traverse their resilient supporting pipes
prior to reaching them, hence those of the said vibratory movements which are not
entirely lost in said resilience are so far checked by it as to have their jerky or
sudden changes of direction so altered as to reduce their damaging actions to a
minimum.
Many and varied forms of coiled supply pipes may be used either for supporting
the burner and its appurtenances above it or for having same suspended beneath,
while ample facilities are afforded for having bye-pass pipes for supplying gas to
a small flame for igniting purposes as occasion or necessity may require or show
to be desirable.
The coiled pipes may further be arranged to form protectors for the glass
chimneys of the burners or they may be made to support reflectors or the like
used in connection with them. Again one coil of pipe may be made to support
two, three of a larger number of burners with their respective bye-pass and other

page_text: appurtenances Or a cluster of burners each supported by its respective coiled
pipe may be arranged on one common or main supply pipe.
To protect the lower edges of the incandescent articles I form a metal shield
to encircle the outer edge of said article and fit as tightly as convenient against
the cylindrical portion of the upper part of the burner while the lower edge of
this shield opens out somewhat in bell-mouth shape to rest upon the part of the
burner which forms the support for the chimney. Ventilating holes are made in
the lower part of the shield to allow the air to flow freely to the flame.
Inder most circumstances it is found that the lower edges of the incandescent
articles deteriorate more quickly than any other parts hence it is desirable to
lower these articles as they thus wear away, so that they will be brought into
the most desirable part of the flame, to accomplish this I make the central support
to have a series of hooks extending vertically so that the supporting or cross piece
may be made to take over one or other of these hooks as its position may find most
appropriate.

COMPLETE SPECIFICATION (AMENDED).
Improvements in or appertaining to Burners for use in Incandescent-
gas-lighting.
I, WILLIAM RICHARD CLAY, of 1, Slater 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 ascertained in and by the following statement, that is to say:―
In connection with incandescent-gas-lighting much inconvenience and
loss is experienced and entailed by reason of the excessive delicacy,
fragility or brittleness of the incandescent substances, or articles produced out of
them, for which reason street, or like public lighting by these incandescent means,
has heretofore been attended with the greatest difficulties since often the vibrations
of the burner caused by a passing vehicle have been sufficient to completely destroy
the useful properties of the incandescent article causing it to break away in pieces
or even to fall to dust Again it has been found to add greatly to the efficiency
of the combustible gas provided it is fed to the flame at a high temperature, while
further, as is well known, the loose edges of the incandescent articles which are in
an ordinary way entirely exposed to the friction of the currents of air flowing to
support combustion, deteriorate and portions of them are broken off long prior
to the other parts of said articles being worn out
To obviate these difficulties by the application of means for counteracting or
otherwise changing the nature of the vibratory actions of the burners and for
enabling the heat of the flame to be transmitted or imparted to or utilized for
heating the combustible gas as it is being fed to the flame as well as by the
application of means for protecting the lower edges of the incandescent article
is the object of this invention and this object I attain by the means hereinafter
described
Reference being made to the accompanying sheets of drawings in which:-
Fig. 1 is elevation of an ordinary street lamp shown as with a portion of the
lantern or cover cut away in order that my improved burner might be more
clearly illustrated within it.

page_text: Fig. 2 is an elevation showing my improved burner in one of its simplest forms.
Fig 3 is a similar elevation to Fig 2 out shows the manner in which a shade
and cover may be applied in connection therewith.
Fig. 4 illustrates a method whereby a single suspended pipe may supply gas
to more than one of my improved burners
Figs. 5 and 6 are side and edge views drawn to an enlarged scale of a part
hereinafter described.
Fig 7 is an elevation illustrative of a method whereby several of my improved
burners may be arranged to be fed and supported by a single supply pipe extend-
ing vertically
Fig 8 is an elevation showing an arrangement of suspending my improved
burner where the use of the heat from the flame is not so extensively employed
for heating the combustible gas fed thereto.
Figs. 9, 10 and 11 are elevations illustrating methods of mounting my improved
burner that I employ when the heating of the combustible gas to be supplied
thereto is not desired.
Figs 12 and 133 are elevation and section of the shield or cover for protecting
the incandescent article.
Figs. 14 and 15 are side and back elevations illustrative of a modification in
the bending of the supply pipe as hereinafter explained.
Similar letters and figures of reference indicate similar parts throughout the
several views.
In carrying my invention into effect I make a portion of the pipe which
conducts gas to the burner a integral with or as part of said burner a and this
part of the supply pipe which I make of an appropriately coiled or spiral form
answers or is used at all times as the support for the burner a and the incan-
descent article c, and since the sand coiled or spiral formation brings the supporting
part into such a condition as to make it have considerable resilience, the parts
supported by it are protected against the damaging effects of the vibratory move-
ments of adjoining bodies for the reason that all such movements have to traverse
this resilient supporting pipe prior to reaching the parts it supports, hence those
of the said vibratory movements which are not entirely lost in the said resilience
of the part b are so far checked by it as to have their jerky or sudden changes of
direction so altered as to reduce their damaging actions on the article c to a
minimum.
In order that the heat of the flame may be utilized for raising the temperature
of the gas suppled to it through the part the coiling of this part b is arranged
to be above and about the incandescent article as shown by Figs 1, 2, 3, 4 and 7
A simple form of coiling the part & is shown by Figs. 1 and 2 while in Fig.
a method is shown whereby a shade or deflector e and cover f might be supported
by the part b Or several of the simple forms of coiled parts b may be arranged
to be supported by a central supply pipe g as shown by Fig. 4.
Again one coiled part b may be formed integrally with several burners in
shown by Fig 7 since in this as well as in all the foregoing cases the counteract-
ing properties of the said resilient part b are brought tully into use, while the
position it occupies enables the heat from the flame to be transmitted to the gas
being fed thereto.
Or instead of the supply pipe being coiled about the burner or its chimney, it
coiled part to form the resilience necessary may be formed as shown by Figs 14
and 15, in which case a ball joint ar to allow oscillation is arranged in the position
above the burner where it may enable the heating of the supply gas to be carried
out.
Further, where the heating of the gas is not to be considered, then the part b
may be either above the burner a as shown by Fig. S or below same as shown by
Figs. 9, 10 and 11 and whenever desired hye-pass pipes à may be arranged with
these burners as shown by Figs 1 and 4. in order to supply gas to a small flame
for igniting purposes as occasion or necessity may require or show to be desirable.

page_text: To protect the lower edges of the incandescent articles c I form a metal shield k
to encircle the outer edge of said article c as shown by Fig 12 as also to fit as
tightly as convenient against the cylindrical part m of the burner a while the
lower edge k¹ of the shield k opens out to somewhat bell-mouth-shape in order that
it may rest upon the part which supports the chimney p. Ventilating holes
being made in the shield k to allow the air to flow freely to the flame.
Under most circumstances it is found that the lower edges of the article c
deteriorate more quickly than any other parts of them, hence it is desirable
to lower these articles as they thus wear away, so that they will be brought into
the most desirable part of the flame. To accomplish this I make the central
supports to have a series of hooks s extending vertically as shown by Figs. 5
and 6 so that the supporting or cross piece of the article c may be made to take
over one or other of these hooks s as its position may be most appropriate.
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. The combination with the parts forming a burner for incandescent-gas-
lighting of a coiled or resilient supply pipe for conducting gas to said burner
substantially as herein specified.
