BRACKETS AND OTHER GAS LAMPS "
GAS
My invention has reference to gasalier gas brackets and other gas lamps such
for example as gas standards table gas lamps and the like and consists of the
improvements herein after described in fixing the glass or enamel globes or shades
of gasaliers gas brackets and other gas lamps to their galleries and also in
supporting perdifumes smoke absorbers reflectors or other articles above the said
globes or shades.
I will describe my invention in connection with a gas bracket.
The gallery on which the globe or shade is supported is preferably connected
to the bracket at one side only. By this method of connection the shadow
thrown downwards by the radial arms in the gallery when it is supported at
its middle is avoided. An arm having motion in a vertical plane is jointed to
the bracket. This arm has motion through an angle of about forty five degrees
on each side of a vertical line and is so situated that when it is brought into
one of its two positions its upper end is situated over the middle of the shade
and when brought into its other position it is clear of the shade. I will call the
first described position of the arm its normal position. The upper end of the said
arm has a fastening by which the perdifume smoke absorber reflector or other
article to be suspended over the shade is connected to the said arm. That part of
the said arm which when the arm is in its normal position is situated near the top
edge of the shade is provided with an ornamental hook like projection which as
the arm is.moved into its normal position passes over the top edge of the shade

page_text: and thereby fixes the shade on the gallery and the said shade cannot be removed
or accidentally displaced until the arm has been thrown back from its normal
position.
Instead of fixing the shade by the hook like fastening described a curved
horizontal arm or a complete ring may be used the said curved arm or ring being
attached to the jointed arm in place of the hook like fastening. When the jointed
arm is in its normal position and the curved arm or ring bears upon part or the
whole of the top edge of the shade and secures it in its place.
When it is not required to support anything above the shade the jointed arm
may terminate at the hook like projection. The jointed arm may be employed for
supporting any article above the shade when the shade is fixed in the ordinary way
or by methods differing from that described.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said Thomas Ford in the Patent Office on the 14th February 1884.

My invention has reference to gasaliers, gas brackets and other gas lamps, such
for example, as gas standards, table gas lamps and the like, and consists of the
improvements hereinafter described in fixing the glass or enamel globes or shades
of gasaliers, gas brackets and other gas lamps to their galleries and also in
supporting perdifumes, smoke absorbers, reflectors or other articles above the said
globes or shades.
I will describe my invention in connection with a gas bracket.
The gallery on which the globe or shade is supported is preferably connected to
the bracket at one side only. By this method of connection the shadow thrown
downwards by the radial arms in the gallery, when it is supported at its middle, is
avoided. An arm having motion in a vertical plane is jointed to the bracket.
This arm has motion through an angle of about forty five degrees on each side of
a vertical line and is so situated that when it is brought into one of its two
positions its upper end is situated over the middle of the shade and when brought
into its other position it is clear of the shade. I will call the first described
position of the arm its normal position. The upper end of the said arm has a
fastening by which the perdifumie, smoke absorber, reflector or other article to be
suspended over the shade, is connected to the said arm. That part of the said arm
which when the arm is in its normal position is situated near the top edge of the
shade is provided with an ornamental hook like projection which as the arm is
moved into its normal position passes over the top edge of the shade and thereby
fixes the shade on the gallery and the said shade cannot be removed or accidentally
displaced until the arm has been thrown back from its normal position.
Instead of fixing the shade by the hook like fastening described, a curved
horizontal arm or a complete ring may be used, the said curved arm or ring being

page_text: attached to the jointed arm in place of the hook like fastening. When the jointed
arm is in its normal position the curved arm or ring bears upon part or the whole
of the top edge of the shade and secures it in its place.
When it is not required to support anything above the shade the jointed arm
may terminate at the hook like projection. The jointed arm may be employed for
supporting any article above the shade when the shade is fixed in the ordinary
way or by methods differing from that described.
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 back elevation Figure 2 in side elevation and Figure 3
partly in section, a portion of a gasalier, gas bracket or other gas lamp provided
with my invention for fixing the globe or shade and for supporting the perdifume
or smoke absorber or other article above the globe or shade. In Figures 1 and 2
the jointed arm which supports the perdifume and by which the globe or shade is
fixed in its gallery is thrown back for permitting of the removal of the globe or
shade from or its replacement in the gallery and in Figure 3 the said arm is
represented in its normal position for fixing the globe or shade and for bringing the
perdifume above and over the middle of the globe or shade in position for use.
The same letters of reference indicate the same parts in the several Figures of
the Drawing.
a is the gallery on which the globe or shade b is supported the said gallery being
connected to the supporting bracket c at one side only so as thereby to avoid the
shadow thrown down by the ordinary radial arms when the gallery is supported at
its middle. The gallery bracket c is connected with the arm of the gasalier or gas
bracket arm or other part of a gas lamp by the connection at d. To the top of the
bracket c an arm e is jointed at e² the said arm e turning in a vertical plane on the
said joint so that it can either take the thrown back position Figures 1 and 2 or
the normal position Figure 3. When in the position Figures 1 and 2 the jointed
arm e is clear of the globe or shade and the said globe or shade can be removed
from or placed upon the gallery a. When in the position Figure 3 the upper end
of the jointed arm e is brought over the middle of the shade and the catch or
hook fon the said arm passes over the top of and engages inside the globe or
shade b and thereby fixes the globe or shade to the gallery. The globe or shade
cannot now be removed or accidentally displaced. In order to remove the globe or
shade the jointed arm e has to be thrown back into the position Figures 1 and 2.
The fixing of the globe or shade by the arm e also brings the perdifume or smoke
absorber g carried by it into position for use. The joint e is so shaped (as
indicated in Figures 2 and 3) that the arm e cannot pass beyond the position
represented in Figure 3. The perdifume g is fastened to the top of the arm e by
the terminal screw knob or head screwed upon a screw pin carried by the said
arm, the perdifume being held between a collar on the jointed arm e and the
bottom of the screw thumb or head has seen in Figure 3.
The jointed arm e may carry a curved horizontal arm or semi-ring or a complete
ring for fixing the globe or shade in the gallery in place of the hook like fastening
or catch f. In this case the curved arm or ring when the jointed arm e is in its
normal position Figure 3 bears upon a part or the whole of the top edge of the
globe or shade and fixes it in its place.
The top of the jointed arm e may carry a reflector or other article above the
globe or shade instead of the perdifume or smoke absorber g, h represented in the
Drawing.
The jointed arm e without the book or catch f, or the curved arm or ring
described, may be used for supporting any required article above the globe or
shade. In this case the globe or shade may be fixed in its gallery in the ordinary
or other convenient way.
Although I have represented my invention in connection with a globe or shade
holder connected to the bracket at one side only yet I wish it to be understood

page_text: that my invention may be applied to globe or shade holders having the ordinary
radial arms.
«
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 of
Improvements in gasaliers, gas brackets and other gas lamps."
First Fixing the glass or enamel globes or shades of gasaliers gas brackets and
other gas lamps to their galleries by means of an arm turning in a vertical plane
and jointed to the top of a bracket to which the gallery is connected, the said
jointed arm when turned into its forward or normal position causing a catch or
look like projection, or a curved arm or complete ring, to engage with or bear upon
the top of the glass or shade and fix it, and when the said jointed arm is thrown
back so as to be clear of the globe or shade, it liberates the globe or shade
substantially as described and illustrated in the accompanying Drawing.
Secondly Supporting a perdifume smoke absorber reflector or other article above
the glass or enamel globes or shades of gasaliers gas brackets and other gas lamps
by means of an arm jointed to the top of the bracket to which the gallery is
connected substantially as described and illustrated in the accompanying Drawing,
whether the said jointed arm be used alone for the purpose described or in
addition thereto for fixing the globe or shade to the gallery.
In witness whereof I the said Thomas Ford have hereunto set niy hand and
seal this eleventh day of February in the year of our Lord One thousand eight
hundred and eighty four.
