IMPROVEMENTS IN HOLDERS OR GALLERIES FOR GLOBES AND SHADES FOR GAS AND OTHER LIGHTS
Year: 1878

page_text: LETTERS PATENT to Joseph Breeden, of Birmingham, in the County of Warwick,
Gas Fitting and Chandelier Maker, for the Invention of "IMPROVEMENTS IN
HOLDERS OR GALLERIES FOR GLOBES AND SHADES FOR GAS AND OTHER
LIGHTS."
Sealed the 7th February 1879, and dated the 30th November 1878.
PROVISIONAL SPECIFICATION left by the said Joseph Breeden at the Office
of the Commissioners of Patents on the 30th November 1878.
JOSEPH BREEDEN, of Birmingham, in the County of Warwick, Gas Fitting and
Chandelier Maker. "IMPROVEMENTS IN HOLDERS OR GALLERIES FOR GLOBES
AND SHADES FOR GAS AND OTHER LIGHTS."
My Invention of improvements in "holders" or "galleries" for supporting
globes and shades used with gas and other lights relates to holders of that class in
which the arms or claws are made to expand and contract to suit different sized
globes and shades, and to enable the globe or shade to be placed and secured in or
on the holder. And it has first for its object to avoid the unsightly appearance of
the double arms and the long screwed stem hitherto used, and to provide a neat and
compact arrangement of expanding holder or gallery, in which the means of adjust-
ment are almost entirely concealed from view.
According to this part of my Invention the radial arms of the holder or gallery
are hinged or pivoted in ears fixed around the central tube of the burner or other-
wise, so that the arms work in vertical planes, in order that by bringing the arms
nearer to the horizontal or the vertical position (as the case may be) their extremi-
ties shall be made to diverge more or less, as required. Each arm has a toothed
sector formed on the pivoted end, concentric with the pivot or axis on which the
arm works, and the several arms are adjusted simultaneously by a tangent screw or
worm gearing with the toothed sectors of all the arms. This worm is fitted to turn
on the central tube of the burner, and is confined between collars or shoulders which
prevent any vertical movement, and it has a milled flange, ornamental knob, or
other convenient means of rotating it. This worm would be concealed from view

page_text: by a downwardly projecting rim or shield. Instead of a screw or worm it might
be a cylindrical rack, gearing with the sectors and connected to a nut screwing on
the burner tube, in which case the rack and nut would have vertical movement, in
order to adjust the arms; this arrangement is therefore less advantageous than the
one before described.
For ordinary chandelier or bracket globes the arms would have hook shaped
claws at the outer extremities, to embrace and grasp the flange of the globe or shade,
or they might be without claws, and be applied to support the globe by being
expanded after being contracted to pass through an aperture in the globe, this latter
mode of applying them being especially suitable for vestibule and such like
lamps.
My Invention relates, secondly, to improvements on the holder or gallery for
which Letters Patent were granted to Henry Horton, dated September 14th, 1876,
No. 3598, and it consists in the following modifications thereof :-
The sliding clips, instead of passing through slots in the ends of the arms of the
carrier, are connected thereto in one of the two following ways, viz. :—
The clips have longitudinal slots, through which pass studs for the clips to slide
upon, fixed to the underside of the arms of the carrier.
Or, instead of studs and slots, the arms of the carrier terminate in small cross-
heads or have lateral projections, and the clips have side flanges turned up and
inwards to embrace the crossheads or projections, and slide thereon.
In either case the clips may be adjusted either by means of a nut traversing a
screw thread on the jet tube, as described in the Specification of the aforesaid
Patent, or the tube may be plain and the nut be replaced by a sliding collar provided
with a set screw to fix it, the point of the set screw being received in a vertical
groove in the jet tube to prevent rotary motion of the collar.

JOSEPH BREEDEN, of Birmingham, in the County of Warwick, Gas Fitting and
Chandelier Maker. "IMPROVEMENTS IN HOLDERS OR GALLERIES FOR GLOBES
AND SHADES FOR GAS AND OTHER LIGHTS."
"
My Invention of improvements in "holders" or galleries" for supporting
globes and shades used with gas and other lights relates to holders of that class in
which the arms or claws are made to expand and contract to suit different sized
globes and shades, and to enable the globe or shade to be placed and secured in or
on the holder. And it has for its object to provide a neat and compact arrangement
of expanding holder or gallery, in which the means of adjustment are almost entirely
concealed from view.
According to my Invention, the radial arms of the holder or gallery are hinged
or pivoted to ears fixed around the central tube of the burner, and the arms work
in vertical planes, so that by bringing them nearer to the horizontal or the vertical
position (as the case may be) their extremities will diverge more or less as required.
In order to adjust the arms, and likewise hold them rigidly in any position in which
they may be set, each arm has a toothed sector concentric with its pivot, and the
several arms are adjusted simultaneously by a tangent screw or worm gearing with
the toothed sectors of all the arms. This worm is fitted to rotate on the central
tube of the burner, and is confined between collars or shoulders to prevent any
vertical movement of the worm, and it has a milled flange, ornamental knob, or
other convenient means of rotating it. This worm may or may not be concealed
from view by a downwardly projecting rim or shield. The arms have hook shaped
claws at the outer extremities to embrace and grasp the flange of the globe or shade
as usual.
In the accompanying Drawings, Figure 1 is an elevation and Figure 2 a plan of
a gas bracket provided with my improved globe holder; and Figure 3 is a central
vertical section of the same, drawn to a larger scale; Figure 4 is an elevation like
Figure 1, but slightly modified.
A is the central or jet tube of the burner; it is plain externally, and B is a short
tube or sleeve fitted to rotate upon it between a shoulder a at bottom and a collar
C at top, soldered or otherwise fixed to tube A. D is a coarse screwthread or worm
cut on the upper part of the sleeve B, and b is a milled flange around the bottom of
said sleeve, by means of which it is rotated. In Figure 1 the collar C has a down-
wardly projecting rim c, which conceals the worm D, but in Figure 4 this rim is
omitted and the worm is visible. E are ears projecting radially from collar C, upon
which they are formed at equal distances apart, and F are the radial arms of the
globe holder or gallery, terminating at their outer ends in claws G, which embrace
the flange of the globe. Each arm F is received at its other end between a pair of
the ears E, and works on a horizontal pivot f fixed therein. H is a toothed sector
formed on this end of each arm F concentrically with its pivot f; the sectors of all
the arms gear with the worm D on tube B, by rotating which the arms are simul-
taneously caused to describe ares of equal length, thereby expanding or contracting
the embrace of the claws G, as indicated by the dotted lines in Figure 3, the claws Ğ
always remaining concentric with the burner. The arins F may be raised until the
claws G are close up to the burner, as indicated at F¹ in Figure 3, so as to occupy
less room and be less liable to injury when packed for carriage. When intended to
support an opal glass or other shade, the holder would be constructed as above

page_text: described, except that the arms F would be of greater length, and the claws at
their extremities would be of a form adapted to embrace the rim of the shade.
Having described the nature of my Invention, and the manner of performing the
same, I declare that what I claim as my Invention to be protected by the herein-
before in part recited Letters Patent is,―
1st. Mounting the arms of gas and other globe and shade holders or galleries to
work on pivots or axes in a support on the burner tube, so that the arms shall be
free to describe arcs of circles, substantially as and for the purpose described.
2nd. In a gas and other globe and shade holder, the combination with the arms
mounted to work on pivots, and provided with toothed sectors as described, of the
worm mounted to rotate and gear with said sectors, substantially as and for the
purpose shown and described.
In witness whereof, I, the said Joseph Breeden, have hereunto set my hand
and seal, this Twenty eighth day of May, in the year of our Lord One
thousand eight hundred and seventy nine.
JOSEPH BREEDEN. (L.S.)
