page_text: LETTERS PATENT to Richard Bagley, of Birmingham, in the County
of Warwick, Machinist, for the Invention of "IMPROVEMENTS IN
HOLDERS OR GALLERIES FOR THE SHADES OR GLOBES AND CHIMNEYS OF GAS
AND OTHER LAMPS, WHICH IMPROVEMENTS ARE ALSO APPLICABLE TO CANDLE
HOLDERA"
Sealed the 4th April 1873, and dated the 10th October 1872.
PROVISIONAL SPECIFICATION left by the said Richard Bagley at the
Office of the Commissioners of Patents, with his Petition, on the
10th October 1872.
I, RICHAD BAGLEY, of Birmingham, in the County of Warwick,
5 Machinist, do hereby declare the nature of the said Invention for "In-
PROVEMENTS IN HOLDERS OR GALLERIES FOR THE SHADES OR GLOBES AND CHIMNEYS
OF GAS AND OTHER LAMPS, WHICH IMPROVEMENTS ARE ALSO APPLICABLE TO CANDLE
HOLDERS," to be as follows:-
My Invention consists of the improvements herein-after described in
constructing the said holders or galleries; the object of my Invention
being principally to facilitate the fixing of the shade, globe, or chimney,

page_text: in, and its removal from the holder or gallery, and also to adjust the
holder or gallery to the diameter of the part of the shade, globe, or
chimney to be held by it. My Invention is also applicable to candle
holders.
I will describe my Invention as applied to the shade or globe holder
of a gas lamp. Supported by and capable of rotating upon the upper
side of the bottom plate of the shade holder are three radial arms, the
inner ends of the said arms being joined to a central ring situated
around the gas burner. The other ends of the radial arms carry sliding
lips or hooks in which the rim or flange of the shade or globe engages.
These sliding lips are connected to the radial arms by pins on the said
lips working in longitudinal slots in the said arms, heads on the said
pius retaining the sliding lips in their places. By sliding the said lips
on the radial arms nearer to or further from the centro of the holder,
they can either be engaged with or made to clip the rim of the shade, or
be removed from the said rim. In the former caso the shade is firmly
secured to the holder, and in the latter case the shade is released and
may be removed from the holder.
The sliding of the fixing lips on the radial arms is effected in the
following manner :-In the bottom plate of the holder or gallery three
equidistant curved slots are made, each slot being excentric to the axis
of the holder and having the same curvature. In the said slots the
pins which connect the sliding lips to the radial arms work. The
result of this arrangement is that when the radial arms are rotated by
means of a collar below the holder or gallery, the said pins move in the
said curved and excentric slots, and cause the sliding lips to simul-
taneously approach one another or separate from one another, the said
sliding lips moving in the direction of radii on the rotating arms
described.
In fixing a shade or globe to a holder constructed according to my
Invention the said shade is placed upon the radial arms on the bottom
plate of the gallery, and the said arms rotated so as to cause the holding
lips to close upon the rim of the shade. By rotating the radial arms in
the opposite direction to that described, the holding lips retire from the
shade, and the latter may be removed. By means of the adjustable lips
described the holder is capable of adapting itself to shades or globes of
different sizes.

page_text: The holder or gallery described may be modified in the following
manner-In place of making the radial arms detached from the ring
or rim of the holder, the said arms may be fixed to or made in one
piece with the said ring or rim; and in place of curved and excentric
slots in the bottom of the holder rotating arms having the same
curvature as the said slots may be employed. In the arrangement the
sliding lips move on the fixed radial arms, the motion of the said lips
being effected by means of the said curved arms engaging with eyes or
loops on the said sliding lips.
The holder or gallery described may be modified in the following
manner-In place of making the radial arms detached from the ring
or rim of the holder, the said arms may be fixed to or made in one
piece with the said ring or rim; and in place of curved and excentric
slots in the bottom of the holder rotating arms having the same
curvature as the said slots may be employed. In the arrangement the
sliding lips move on the fixed radial arms, the motion of the said lips
being effected by means of the said curved arms engaging with eyes or
loops on the said sliding lips.
In applying my Invention to the chimney holders and to candle
holders, I construct and arrange the parts substantially in the manner
herein-before described with respect to a shade or globe holder.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Richard Bagley in the Great Seal Patent Office on
the 8th April 1873.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, RICHARD
BAGLEY, of Birmingham, in the County of Warick, Machinist, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Tenth day of October, in the year
of our Lord One thousand eight hundred and seventy-two, in the
thirty-sixth year of Her reign, did, for Herself, Her heirs and suc-
cessors, give and grant unto me, the said Richard Bagley, Her special
license that I, the said Richard Bagley, my executors, administrators, and
assigns, or such others as I, the said Richard Bagley, my executors,
administrators, and assigns, should at any time agree with, and no
others, from time to time and at all times thereafter during the term
therein expressed should and lawfully might make, use, exercise, and
vend, within the United Kingdom of Great Britain and Ireland, the
Channel Islands, and Isle of Man, an Invention for "IMPROVEMENTS IN
HOLDERS OR GALLERIES FOR THE SHADES OR GLOBES AND CHIMNEYS OF GAS AND
OTHER LAMPS, WHICH IMPROVEMENTS ARE ALSO APPLICABLE TO CANDLE HOLDERS,"
upon the condition (amongst others) that I, the said Richard Bagley,
my executors or administrators, by an instrument in writing under

page_text: my, or their, or one of their hands and seals, should particularly
describe and ascertain the nature of the said Invention, and in what
manner the same was to be performed, and cause the same to be filed
in the Great Seal Patent Office within six calendar months next and
immediately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said Richard Bagley, do hereby declare
the nature of the said Invention, and in what manner the same is to be
performed, to be particularly described and ascertained in and by the
following statement thereof, that is to say :—
My Invention consists of the improvements herein-after described in
constructing the said holders or galleries, the object of my Invention
being principally to facilitate the fixing of the shade, globe, or chimney
in and its removal from the holder or gallery, and also to adjust the
holder or gallery to the diameter of the shade, globe, or chimney to be
held by it.
I will describe my Invention as applied to the shade or globe holder of
a gas lamp. Upon the upper side of the bottom plate of the shade holder
are three radial arms, the inner ends of the said arms being joined to a
central ring situated around the gas burner. The other ends of the radial
arms carry sliding lips or hooks in which the rim or flange of the shade or
globe engages. The sliding lips are connected to the radial arms by pins
on the said lips, working in longitudinal slots in the said arms, heads on
the said pins retaining the sliding lips in their places. By sliding the
said lips on the radial arms nearer to or further from the centre of the
holder, they can either be engaged with or made to clip the rim or flange
of the shade, or be removed from the said rim. In the former caso the
shade is firmly secured to the holder, and in the latter case the shade is
released and may be removed from the holder.
The sliding of the fixing lips on the radial arms is effected in the
following manner :-In the bottom plate of the holder or gallery three
equidistant curved slots are made, each slot being excentric to the axis
of the holder and having the same curvature. In the said slots the pins
which connect the sliding lips to the radial arms work. The result of
this arrangement is that when the shade holder or radial arms aro rotated
the said pins move in the curved and excentric slots described, and cause
the sliding lips to simultaneously approach one another or separate from
one another, the said sliding lips moving in the direction of radii on the
radial arms described.

page_text: In fixing a shade or globe to a holder constructed according to my
Invention, the said shade is placed upon the radial arms of the holder
and the bottom plate, or the radial arms rotated so as to cause the
holding lips to close upon the rim of the shade. By rotating the radial
arms or the bottom plate of the holder in the opposite direction to that
described, the holding lips retire from the shade, and the latter may be
removed. By means of the adjustable lips described the holder is
capable of adapting itself to shades or globes of different sizes.
In place of curved and eccentric slots in the bottom of the holder, arms
baving the same curvature as the said slots may be employed. In this
arrangement the motion of the holding lips on the radial arms is effected
by means of the said curved eccentric arms, engaging with eyes or loops
on the said sliding lips.
In applying my Invention to chimney holders and to candle holders,
I construct and arrange the parts substantially in the manner herein-
before described with respect to a shade or globe holder.
Having explained the nature of my Invention I will proceed to
describe with reference to the accompanying Drawing the manner in
which the same is to be performed.
Figure 1 represents in plan of upper side, Figure 2 in section, and
Figure 3 in elevation a shade holder or gallery constructed according to
my Invention Figure 4 is a plan, and Figure 5 an edge view of the
bottom plate of the holder detached. The same letters of reference
indicate the same parts in Figures 1, 2, 3, 4, and 5.
a is the bottom plate of the shade holder resting upon the collar 6 on
the gas burner pipe c; d, d, are the radial arms of the shade holder
situated on the upper side of the said bottom plate a. The inner ends of
these radial arms are joined to a central ring which is fixed to the gas
burner pipe c by screwing. The outer ends of the radial arms carry
sliding lips or hooks e, e, for clipping the rim or flange of the shade or
globe to be held in the gallery. The said sliding lips or hooks e are
connected to the radial arms d, d, by pins f which work in longitudinal
slots in the said radial arms, so that by sliding the said lips on the
said arms they can be brought nearer to or further from the centre of
the shade holder. In the bottom plate a of the holder are three qui-
distant curved slots i, i, each slot i being eccentric to the holder, and
each slot having the same curvature (see Figures 1 and 4). The stems

page_text: of the pins which connect the sliding lips e to the radial arms d, d, pass
through the curved eccentric slots i, i, heads on the said pins working ou
the under side of the bottom plate a of the holder. By means of the
said pins the sliding lips e are connected to the radial arms f, and also
to the bottom plate a of the holder, the said pins being capable of sliding
in the longitudinal slots in the arms d, and also in the eccentric curved
slots in the bottom plate a.
By rotating the bottom plate a of the shade holder in one or other
direction the curved eccentric slots i move upon the pins f, and cause
the sliding lips c, c, to simultaneously approach one another, or separate 1
from one another, the said sliding lips c, e, moving in the direction of
radii on the arms d, d.
To fix the shade or globe to the holder the said shade is placed upon
the radial arms d, d, and the bottom plato a is rotated so as to cause the
holding lips e, e, to close upon the rim of the shade, and thereby fix it 1
in its place in the holder. To release the shade or globe the bottom
plate a is rotated in the opposite direction. The holding lips c, c, are
thereby made to retire from the shade when the latter is released, and
may be removed from the holder.
The sliding motion may be given to the holding lips c, e, by making
the bottom plate a stationary, and giving rotation to the radial arms d, d.
In this arrangement the bottom plate a is fixed to the gas burner pipe c,
and a tubular collar connected with the radial arms is situated around
the said pipe c and below the bottom plate a, the radial arms being
rotated by means of the said tubular collar.
By constructing and arranging the parts of the holder in the manner
described, the adjustablo lips e, e, are capable of adjusting themselves
to the size of the shade or globe to be held in the holder or gallery.
Figure 6 represents in plan of upper side, and Figure 7 in section a
shade holder ar gallery constructed according to my Invention, in which a
curved eccentric arms on the bottom plate a are used instead of curved
eccentric slots. In the said Figures 6 and 7 the curved eccentric arms
of the bottom plate a are marked 1, and the sliding lips of the fixed
radial arms & are marked e. In this arrangement the radial arms d are
without longitudinal slots, and the sliding lips e are made to clip the a
sides of the said arms d. The bottom of each sliding lip e is furnished
with an cyc or loop m (see Figure 7) which works upon the excentric

page_text: arm of the bottom plate a. By this means the sliding lips e are con-
nected to the radial arms d, and also to the bottom plate a. By rotating
the bottom plate a, its eccentric arms 1, 1, move within the eyes or
loops m of the sliding lips e, and by their excentricity slide the said lips
nearer to or further from the axis of the holder, so as to make them clip
the rim of the shade, or release the said rim. The bottom plate a in this
arrangement may be fixed, and the radial arms d be capable of rotation ;
but I prefer to use the arrangement represented in the Drawing.
Figure 8 represents in plan of upper side, Figure 9 in vertical
section, and Figure 10 in plan of under side a candle holder constructed
according to my Invention. In this arrangement I make in the rotating
nozzle n of the candle holder a series of curved excentric slots p, p, and
between the said nozzle and the top plate 9 sliding lips or arms r, r,
work, pins & on the said lips or arms engaging in the curved excentric
slots p, p, in the nozzle. The top plate q is fixed-to the tubular part t of
the candle holder. The horizontal parts of the lips or arms work in
guides u in the under side of the top plate q. The nozzle n is supported
by and works upon the annular shoulder von the tubular part t. By
rotating the nozzle n the excentric slots p work upon the pins 8, 8, of the
arms or lips r, r, and slide the said lips or arms nearer to or further from
the axis of the holder, so as to clip or release the candle. In the
Drawing the bent parts of the arms or lips are represented in position
to clip the candle.
The improvements described and represented with slight modifications
may be used for holding lamp chimneys.
Having now described the nature of my Invention, and the manner in
which the same is to be performed, I wish it to be understood that I do
not limit myself to the precise details herein described and illustrated,
as the same may be varied without departing from the nature of my
Invention,-
But I claim as my Invention the improvements in holders or galleries
for the shades or globes and chimneys of gas and other lamps, and in
candle holders, herein-before described and illustrated in the accom-
panying Drawing, that is to say, constructing the said shade holders or
galleries or chimney holders of a bottom plate and a series of radial arms
provided with sliding or adjustable lips, by which lips the shade or globe
or chimney is held, the said sliding or adjustable lips being made to

page_text: close upon and clip the shade or globe or chimney, or be removed there-
from by means of curved eccentric slots in, or curved eccentric arms
carried by the said bottom plate, acting upon the sliding or adjustable
lips, substantially as described and illustrated in Figures 1, 2, 3, 4, 5, 6,
and 7.
Also the combination or arrangement of the parts of candle holders,
herein before described and illustrated in Figures 8, 9, and 10.
In witness whereof, I, the said Richard Bagley, have hereunto set
my hand and scal, this Second day of April, in the year of our
Lord One thousand eight hundred and seventy-three.
