CUMPLIMIE DIEUIFICATION,
Improvements in Brackets, Chandeliers, and analogous Fittings for
Gas and other Lighting.
I, CLIFFORD WILLIAM KEMP, of the Firm of Ingram and Kemp, of London Works,
Newtown Row, in the City of Birmingham, Manufacturer, 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:-
This invention has relation to brackets, chandeliers and similar fittings for
gas and other lighting, but is particularly applicable to suspension incandescent
gas lamps, and has for one of its objects, to so arrange the superimposed parts
of the suspension fittings that the same come wholly out of the path and without
the influence, of the fumes and productions of combustion discharged from the
chimney, and for another object, to provide an efficient and automatic means of
detachably securing the globe holder or gallery to the burner or contiguous part
of the lamp or fitting.
Figure of the accompanying drawings represents a perspective view of a
suspension bracket for an incandescent gas lamp constructed and arranged in
accordance with one form of my invention.
Figure 2 represents an elevation of the said bracket or fitting upon an enlarged
scale.
Figure 3 is a top side plan of the said fitting, showing the spiral or volute
character of the arm from which the pendent support of the burner, globe and
chimney depends whereby the whole of the parts of the said arm are removed out
of the influence of the heated vapors arising from the gas flame.
Figure 4 is an elevation of the burner part of the suspension fitting, showing
the detachable globe holder or gallery (which is shown partially in section)
removed.
Figure 5 is a like elevation as Figure 4, but with the globe holder secured in
position to the fitting.
The same letters of reference indicate corresponding parts in the said figures 1
to 5.
a, is the bracket arm (also constituting the gas supply pipe) which is evolved
or continued into a volute or spirally curved carrier, whose inner coil or turn w³,
comprehends or encloses a central space or clearance a², of larger diameter than
that of the chimney coming immediately thereunder, so that all fumes or products
of combustion arising out of the said chimney pass upwards through the middle
clearance space without coming in contact with the coils of the superimposed
carrier or bracket-arm, thus preventing the tarnishing or discoloration of the
polished metal of the bracket by the said fumes. At the inner termination a³, of
the volute coiled carrier arm, the gas-way pipe is continued downwards into a
branch ¹, which both forms one member of a pendent double armed support b
for the burner c, and also supplies gas to the said burner. The other branch or
member 6, of this support may be connected to the bracket a, at a point opposite
to the termination a, and may either also serve as a gas pipe, or simply as a
dead suspension branch of the fitting. The chimney & may be carried by the

page_text: usual gallery on the burner, and is located between the branches b³, 63, of the
said pendent, and the products of combustion ascend and passing out of the
mouth of the said chimney proceed through the coincident middle clearance a³,
without coming at all into contact with the metal of the bracket.
The globe e which may surround the pendent burner support and chimney, is
carried by a separable or detachable gallery f, connected to the burner by means
of spring or yielding catches g, fixedly secured at their upper ends to, and
depending from, the body of the stop-cock casing e, and having inclined free
ends g, terminating in rest shoulders g, adapted to engage underneath the
collar of the globe holder. The underside of the body has a neck, whose
diameter is equal to the inside diameter of the collar f, whilst the distance
between the stop shoulder . and rest shoulders 92, is equal to the depth of the
said collar fo.
The construction of the bracket or fitting necessitates that the globe should be
introduced into position from below and the connection of its holder to the burner
is effected by passing the same ver cally upwards and introducing its collar onto
and over the inclined tips of the spring catches, which are thereby forced together
and closed into clearances 4, provided behind them, but immediately the
shoulders, come below the collar 2, the said catches are again free to expand
outwardly and their rest shoulders g² snap underneath the lower edge of the
said collar, which by fitting onto the extension or neck 2, of the burner is
rigidly and securely connected to the said burner.
The detachment of the globe and globe holder is effected by closing together
the free tail ends of the spring catches by means of the finger and thumb of one
hand whilst grasping the extension, by the remaining fingers to obtain a
firmer grip, and then when the shoulders g², have been closed in clear of the edge
of the collar, the globe holder, which is held by the other hand, is allowed
to slide vertically off the neck of the burner.
Instead of supporting the burner from a double branched pendent, it may be
carried by only a single branch gas-way proceeding from the coiled arm of the
bracket, or the burner may be carried by a pendent having three or more branches
whilst as a further modification, instead of the bracket arm being of the volute
or spiral may be of an oval or elliptical configuration, or instead of making it of
a spiral or volute form, it may be completely circular or elliptical in figure in the
form of a ring or halo, with the pendent burner support having one, two or more
branches as may be desired. The curved parts may be made from continuous
lengths of tubing, or from two or more sections of tubes connected together
by ornamental or other junctions.
A series of these pendent brackets may be arranged around a central support
of suitable design to form a chandelier.
The application of my invention to pendent brackets for oil and other lights
differs in no essential respect from its application to gas lamps as herein described.
The means for detachably connecting globe or shade holders herein described
may be used in connection with any construction of pendent lamp.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is:-
First A pendent support for gas lights, consisting of a bracket or gas-way
arm fashioned into or having a volute or spiral part and continued into. or having
proceeding from it. a depending branch in communication with the burner,
whose chimney is lignable with a clearance or space comprehended by the coils
of the superimposed arm. substantially as and for the purpose herein described
and also as set forth in the accompanying drawing.
Secondly: A pendent support for gas lights, consisting of a bracket or gas
way arm of a circular or elliptical figure, having proceeding from it, a depending
branch in communication with the burner, whose chimney is lignable with a

page_text: clearance or space comprehended by the bracket, substantially as and for the
purpose herein described.
Thirdly-In pendent gas and other lamps in which the shade or globe is
introduced into position from below, detachably connecting the globe or shade
holder or gallery to the lamp by means of one, two or more automatically locking
spring catches or shouldered arms, carried by the lamp and having their free
tail ends formed into or provided with inclined planes, substantially as herein
described and also as set forth in the accompanying drawing.
Dated this 15th day of December 1899.
