Gasaliers and Gas Brackets.
I CHARLES HARRIS of No. 68 Park Road Hockley Birmingham in the County of
Warwick Glass Mould Maker do hereby declare the nature of this Invention to be as
follows:-
:-
The object of my invention is to increase when occasion requires it the illuminating
power of ordinary gas chandeliers or gasaliers and gas brackets by adapting thereto a
removable group of burners the said group of burners being constructed and applied
to the gas chandelier or gasalier or gas bracket substantially as hereinafter described.
The said removable group of burners consists of a central screw socket or screw and
gas way in connection with which gas way is a series of three four or other number of
radial arms the outer end of each radial arm being furnished with a gas burner and
a globe or shade holder similar to those of the radial arm of an ordinary gasalier. The
summit of the scrow socket or screw and central gas way described is furnished with a
gas burner and globe or shade holder. I prefer to make the central burner of the
group of burners of larger size than those at the ends of the radial gas arms but I do
not limit myself thereto as the several burners may be of the same size.
The central screw socket or screw of the group of burners is capable of being
screwed after the removal of the ordinary burner onto the arm of the gas bracket or
onto one of the arms of a gas chandelier or gasalier. When the group of burners is
thus adapted to the gas bracket or gasalier three four or other number of burners are
added to the gas bracket or gasalier in place of the single burner removed and the
illuminating power of the gas bracket or gasalier is thereby correspondingly
increased.
The use of my invention does not necessitate any change in the construction of
the gas bracket or gasalier to which it is to be applied as the central screw socket
or screw of the group of burners screws onto the gas arm from which the ordinary
burner has been removed as before described.
When the group of burners is not required it can be removed by unscrewing it
from the gas arm and again screwing the ordinary burner in its place.
Dated this Seventeenth day of December 1886.

I CHARLES HARRIS of No. 68 Park Road, Hockley, Birmingham in the County of
Warwick, Glass Mould Maker do hereby declare the nature of my Invention and in
what manner the same is to be performed to be particularly described and ascertained
in and by the following statement:-
The object of my invention is to increase when occasion requires it the illuminating
power of ordinary gas chandeliers or gasaliers and gas brackets by adapting thereto
a removable group of burners, the said group of burners being constructed and
applied to the gas chandelier or gasalier or gas bracket substantially as hereinafter
described. The said removable group of burners consists of a contral screw_socket
or screw and gas way in connection with which gas way is a series of three, four or
other number of radial arms the outer end of each radial arm being furnished with
a gas burner and a globe or shade holder similar to those of the radial arm of an
ordinary gasalier. The summit of the screw socket or screw and central gas way
described is furnished with a gas burner and globe or shade holder.
The central screw socket or screw of the group of burners is capable of being
screwed, after the removal of the ordinary burner, onto the arm of the gas bracket
or onto one of the arms of a gas chandelier or gasalier. When the group of burners
is thus adapted to the gas bracket or gasalier three four or other number of burners
are added to the gas bracket or gasalier in place of the single burner removed and
the illuminating power of the gas bracket or gasalier is thereby correspondingly
increased.
The use of my invention does not necessitate any change in the construction of the
gas bracket or gasalier to which it is to be applied as the central screw socket or screw
of the group of burners screws onto the gas arni from which the ordinary burner has
been removed as before described.
When the group of burners is not required it can be removed by unscrewing it
from the gas arm and again screwing the ordinary burner in its place.
Figure 1 of the accompanying Drawing represents in side elevation and Figure 2
in plan the removable group of burners constructed according to my invention;
Figure 3 represents a side clevation partly in vertical section of the same (without

page_text: the shades) applied to the arm of a gas bracket or to one of the arms of a gas
chandelier or gasalier; Figure 4 represents in vertical section and Figure 5 in
horizontal section a portion of the group of removable burners drawn to a larger
scale.
The same letters of reference indicate the same parts in the several Figures of the
Drawing.
is
a, b is the central gas way through which the whole of the group of burners is
supplied with gas from the gas bracket or chandelier arm. The said central gas way
a, b consists of the lower conical part a to the summit of which the upper part bis
screwed the said upper part b carrying the central gas burner c and its shade or
globe Fitting on the outside of the conical gas way a is a hollow boss or gas
supply chamber d to which a series of three (or more) radial gas arms e, e, e
connected the outer end of each radial arm e being furnished with a gas burner fand
a globe or shade g. By screwing the upper part of the central gas way upon the
summit of the lower part a the hollow boss or gas supply chamber d is fixed in its
place. The central burner c of the group of burners may be made of larger size than
the burners f,ff at the ends of the radial gas arms e, e, e but I do not limit myself
thereto as the central and outer burners may be of the same size.
The group of burners represented is screwed to the elbow ² at the end of the gas
bracket arm h shown in Figure 3; or to one of the arms of a gas chandelier or gasalier
by means of the screwed socket a² at the bottom of the gas way a, or by means of a
hollow screw at the bottom of the gas way a, the ordinary burner having been
previously removed from the said elbow h².
The gas chamber d carrying the radial gas arms e, e, e is capable of a semi rotation
upon the conical gas way a for the purpose of supplying gas to or cutting off the
supply of gas from the said gas arms e, e, e and their burners. The motion of the
said gas chamber d is limited by a stop i on the central gas way a working in a
cutaway part at the bottom of the said gas chamber d (see Figure 4). In the central
gas way a is a passage k and in the wall of the gas chamber dis another passage
opening into the gas chamber. By turning the gas chamber d in one direction the
passage in it is made to coincide with the passage in the fixed gas way a and
gas is supplied from the gas chamber to the whole of the outer burners f,f,f. By
turning the gas chamber so that its passage is moved from opposite the
passage in the fixed gas way the supply of gas is cut off from the outer
burners. The gas is supplied to and cut off from the central burner c inde-
pendently of the supply to the outer burners f,f,f in the following manner.
Near the top of the upper part b of the central gas way are two passages p, q separated
by the division represented in Figure 4. Around the outside of the part 6 of the
central gas way is a rotating collar the motion of which is limited by a stop pin
and slot at t. In one side of the rotating collar is a small chamber or gas way s
by which the two gas passages p, q can be connected. When the collar is so turned
that it is brought into the position represented in Figure 4 the two passages p, gare
connected and the gas from the central gas way b passes through the passage p into
the small chambers and from thence by the other passage q to the burner c. By
turning the collar r so that its small chambers is moved from the two passages P, q
the gas supply is cut off the central burner c.
No tap or stop cock is required on the bracket arm h.
By this arrangement the whole of the outer small burners ƒ, ƒ, ƒ can be used
without the central burner c, or the central burner c may be used without the small
outer burners, ff, or all the small outer burners fff and the central burner c may
be used together.
-
When the group or a portion of the group of burners is thus added to the gas
bracket arm or to the arm of the gasalier, three or four (or other number of) burners
are added to the gas bracket or arm of the gasalier in place of the single burner
removed and the illuminating power of the gas bracket or gasalier is thereby
correspondingly increased. If required the upper part 6 of the central gas way
carrying the central burner may be unscrewed from the lower part a of the said gas

page_text: way and the said upper part b be applied to any existing gas chandelier arm or bracket
arm.
Having now particularly described and ascertained the nature of my invention and
the manner in which the same is to be performed 1 declare that I claim as my
invention of "An improvement in or addition to gas chandeliers or gasaliers and gas
brackets."
Combining with one or more of the arms of a gas chandelier or gasalier or with the
arm of a gas bracket in place of the ordinary burner or burners a group of burners
constructed arranged and used substantially as hereinbefore described and illustrated
in the accompanying Drawing for the purpose when required of increasing the
illuminating power of the gas chandelier or gasalier or gas bracket.
Dated this Twenty second day of August 1887.
