My invention consists in constructing and combining the parts of the said holders
or galleries in the manner hereinafter described whereby the holders or galleries
are made to support the whole of the lower edges of the globes or shades instead
of supporting the globes or shades at three points only as in holders of the ordinary
kind; and also to fix the shades or globes to the holders or galleries without the
unsightly external hook like clips ordinarily employed.
In making a holder or gallery for the globe or shade of a gas or other lamp
according to my invention I make preferably of sheet metal and by the action of
dies worked in a stamp or press a ring or gallery of a size suitable to receive the
bottom edge of the globe the said ring or gallery having two fixed radial arms and
a small central perforated disc by which the gallery is attached to the gas or other
lamp. The said arms make with each other an angle of one hundred and twenty
degrees. The arms and central disc are not in the same plane as the ring or
gallery but incline downwards from the ring or gallery to the central disc. The
said ring is concave on its upper side and carries at its inner edge and midway
between the two fixed arms a small hook like clip under which the edge of the
globe engages when in its place on the holder or gallery.
A third and moveable arm is connected at its inner end with the central

page_text: perforated disc upon which it turns as a centre the outer end of the said moveable
arm travelling upon the ring. The said moveable arm has motion through an
angle somewhat less than one hundred and twenty degrees its motion being limited
by stops or shoulders formed by making the part of the ring traversed by the
moveable arm of somewhat less breadth than the other portion. The extreme end
of the moveable arm is turned up so as to make an acute angle with the plane of
the ring. A knob on the underside of the moveable arm and near its end affords
the incans of moving it.
The holder is used as follows:-The moveable arm is turned in the direction
proper to bring it as near as possible to the hook like clip on the inner edge of the
ring or gallery. The globe is then placed upon the ring or gallery the said hook
like clip and the turned up end of the moveable arm both bearing on the inside of
the globe. By now turning the moveable arm in the direction opposite to that last
described until it comes against the shoulder limiting its motion it is brought into
a position equidistant between the two fixed arms. and the globe is fixed in its
place on the ring or gallery the fixed hook like clip and the end of the moveable
arm pressing upon the inside of the globe at opposite points and fixing it down
upon the ring. In order to remove the globe the moveable arm is turned until its
end is brought near the clip on the ring when the globe can be lifted from
the ring.
The knob by which the moveable arm is moved may be rigidly fixed to the
arm or may be connected by a screw. In the latter case by tightening the screw
the moveable arm may be clamped in its place and can only be moved after
slackening the screw.

My invention consists in constructing and combining the parts of the said holders
or galleries in the manner hereinafter described, whereby the holders or galleries
are made to support the whole of the lower edges of the globes or shades instead
of supporting the globes or shades at three points only as in bolders of the ordinary
kind and also to fix the shades or globes to the holders or galleries without the
unsightly external hook like clips ordinarily employed.
In making a holder or gallery for the globe or shade of a gas or other lamp
according to my invention I make, preferably of sheet metal and by the action of
dies worked in a stamp or press, a ring or gallery of a size suitable to receive the
bottom edge of the globe the said ring or gallery having two fixed radial arms and
a small central perforated disc by which the gallery is attached to the gas or other
lamp. The said arms make with each other an angle of one hundred and twenty
degrees. The arms and central disc are not in the same plane as the ring or
gallery but incline downwards from the ring or gallery to the central disc. The
said ring is concave on its upper side and carries at its inner edge and midway
between the two fixed arms a small hook like clip under which the edge of the
globe engages when in its place on the holder or gallery.
A third and moveable arm is connected at its inner end with the central
perforated disc upon which it turns as a centre, the outer end of the said moveable
arm travelling upon the ring. The said moveable arm has motion through an
angle somewhat less than one hundred and twenty degrees its motion being limited.
by stops or shoulders formed by making the part of the ring traversed by the
moveable arm of somewhat less breadth than the other portion. The extreme end
of the moveable arm is turned up so as to make an acute angle with the plane of
the ring. A knob on the underside of the moveable arm and near its end affords.
the means of moving it.
The holder is used as follows:-The moveable arm is turned in the direction
proper to bring it as near as possible to the hook like clip on the inner edge of the
ring or gallery. The globe is then placed upon the ring or gallery the said hook
like clip and the turned up end of the moveable arm both bearing on the inside of
the globe. By now turning the moveable arm in the direction opposite to that last
described until it comes against the shoulder limiting its motion, it is brought into
a position equi distant between the two fixed arms and the globe is fixed in its
place on the ring or gallery, the fixed hook like clip and the end of the moveable
arm pressing upon the inside of the globe at opposite points and fixing it down.
upon the ring. In order to remove the globe, the moveable arm is turned until
its end is brought near the clip on the ring when the globe can be lifted from
the ring.
The knob by which the moveable arm is moved may be rigidly fixed to the
arm or may be connected by a screw. In the latter case by tightening the screw,
the moveable arm may be clamped in its place and can only be moved after
slackening the screw.

page_text: I will now proceed to describe with reference to the accompanying Drawing the
manner in which my invention is to be performed
Figure 1 represents in plan of upperside and Figure 2 in vertical section a globe
holder or gallery for a gas or other lamp in combination with a globe or shade, the
said holder or gallery being constructed according to my invention. In Figure 1
the globe or shade is represented in horizontal section and the section of the holder
or gallery in Figure 2 is taken through the fixed hook like clip and the moveable
arm of the globe holder; Figure 3 represents in side elevation and Figure 4 in plan
of upper side the globe holder without a globe and Figure 5 represents in side
elevation and plan the moveable arm of the globe holder detached.
The same letters of reference indicate the same parts in the several Figures of
the Drawing.
a is the ring or gallery of the globe holder made either of sheet metal by stamping
or by casting. The said ring or gallery a has the concave sectional form represented
at the right hand side of Figure 2 for receiving the bottom edge of the globe or
shade b; c, c are the fixed radial arms of the gallery connected with a central
perforated disc or support d and making with each other an obtuse angle as repre-
sented. The planes in which the arms c, c and disc or support d are situated with
respect to the gallery a will be understood by reference to Figure 3. The said
central disc or support d is screwed internally for screwing on the gas burner
as usual; e is a small hook like clip on the gallery a under which clip the
edge of the globe b engages when in its place on the said gallery (see Figure 2).
This clip is situated at the inner edge of the gallery a and midway between the two
fixed arms cc; f is the moveable arm of the globe holder (shown separately in
Figure 5) having motion in a horizontal plane.
The inner end of the said moveable arm f is furnished with a ring or eye f³
which turns as a centre upon the central disc or support d of the globe holder, the
said ring or eye f² being supported upon a shoulder on the said central disc and
the said ring f2 is secured in its place by the turning over or burnishing of the top
of the central disc upon the upper edge of the said ring (see the section Figure 2).
The extreme end f³ of the moveable arm f is turned up so as to make an acute
angle with the gallery a. The inner edge of the gallery a through a portion of its
length is cut away at g so as to form shoulders hi which act as stops to limit the
motion of the moveable arm f, the said moveable arm having motion through an
angle of about ninety degrees, but the angle may be greater or less. The upper
end of the moveable arm f bears upon the said cut away part at g and the said
arm is moved by the knob f on its underside.
In order to place and fix the globe or shade in the holder the moveable arm fis
moved to the position represented in Figure 4 so as to cause it to bear against the
stop and approach the fixed hook like clip e. The holder is now ready to receive
the globe the edge of which is placed in the concave gallery a both the fixed hook
like clipe and the turned up end f3 of the moveable arın f bearing on the inside of
the globe b. By now turning the moveable arm f into the position represented in
Figure 1 and making it bear against the other stop h the said arm is brought into
a position equi-distant between the two fixed arms c. c of the gallery as represented
in Figure 1. When the moveable arm f is in the last described position, the fixed
hook like clip c and the end ƒ³ of the said arm f are pressing upon the inside of
the globe bat opposite points and the said globe is thereby fixed securely in the
gallery a. By turning the moveable arm finto the position represented in Figure 4
the globe is released and may be lifted from the gallery.
The knob f by which the moveable arm f is turned, may either be rigidly fixed
on the screw pin carrying it; or the said knob may be made capable of screwing
upon the said screw pin. When the knob f* turns on the screw pin it may be made
to act as a small clamp to bind the moveable arm f upon the gallery a after the
said arm has been turned to fix the globe, the moveable arm being released by
slackening the knob upon the screw pin. As the edge of the globe when fixed to

page_text: the holder is held at opposite points by the parts a, e and a, ƒ³ (see Figure 2) the
globe and holder may be inverted with safety, that is, the holder may be uppermost
and the globe suspended therefrom with safety where for any reason that position
of the holder and globe is desirable.
.
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 claim as my invention―
The improvements in holders or galleries for holding and fixing the globes or
shades of gas and other lamps herein before described and illustrated in the accom-
panying Drawing; that is to say, the combination with the ring or gallery of the
globe or shade holder of the fixed hook like clip e and moveable arm ƒ ƒ³, ƒ³, ƒ^
travelling upon the said ring or gallery and having its angular motion limited by
stops h, i on the said ring or gallery, the end of the said moveable arm when brought
opposite the said fixed clip fixing the globe or shade in the holder and when turned
aside so as to approach one of the fixed arms of the gallery releasing the said globe
or shade substantially as described and illustrated.
In witness whereof I the said Thomas Carpenter have hereunto set my hand
and seal this Twenty ninth day of May in the year of our Lord one thousand
eight hundred and eighty three
