IMPROVEMENTS IN APPARATUS USED WITH GAS OR OTHER LIGHTS FOR HOLDING THE GLOBES OR OTHER GLASSES USED THEREWITH."
Year: 1880

page_text: LETTERS PATENT to William Bethell Wilkinson, of the Town and County
of the Town of Kingston-upon-Hull, Brass Founder, for an Invention of
"IMPROVEMENTS IN APPARATUS USED WITH GAS OR OTHER LIGHTS FOR
HOLDING THE GLOBES OR OTHER GLASSES USED THEREWITH."
PROVISIONAL SPECIFICATION left by the said William Bethell Wilkinson
at the Office of the Commissioners of Patents on the 19th February 1880.
WILLIAM BETHELL WILKINSON of the Town and County of the Town of Kingston
upon Hull, Brass Founder. " IMPROVEMENTS IN APPARATUS USED WITH GAS OR
OTHER LIGHTS FOR HOLDING THE GLOBES OR OTHER GLASSES USED THEREWITH."
The object of the Invention is to render the holding of "globes," "moons," or
other glasses used with gas and other lights more secure on their supporting arms
or galleries, and the improvements particularly apply to glasses formed without
collars or lips, and at the same time to prevent cracking or breakage of the glass
by excessive local holding pressure.
For this purpose, in addition to the outer horn or support to each arm rising up
the outside of the glass, I also apply a short inner horn to rise a short distance up
the inside of the glass, and to one of these supporting arms I also apply an
additional arın to turn upon an axis so as to be capable, when the glass is applied,
of being turned upwards to lie against or near to the inside of the glass, and of
being held in that position by screwing.
By these means the glass will be securely held from being readily moved off the
supports and without risk of fracture to the glass by excessive local pressure.

the said Williain Bethell Wilkinson in the Great Seal Patent Office on the
14th August 1880.
WILLIAM BETHELL WILKINSON, of the Town and County of the Town of Kingston-
upon-Hull, Brass Founder. "IMPROVEMENTS IN APPARATUS USED WITH GAS OR
OTHER LIGHTS FOR HOLDING THE GLOBES OR OTHER GLASSES USED THEREWITH."
The object of the Invention is to render the holding of "globes," " moons," or
other glasses used with gns and other lights more secure on their supporting arms
or galleries, and the improvements particularly apply to glasses formed without
collars or lips, and at the same time to prevent cracking or breakage of the glass
by excessive local holding pressure.
For this purpose, in addition to the outer horn or support to cach arm rising up
the outside of the glass. I also apply to each a short inner horn to rise a short
distance up the inside of the glass, and to one of these supporting arms I also apply
an additional arm to turn upon an axis so as to be capable, when the glass is
applied, of being turned upwards to lie against or near to the inside of the glass,
and of being held in that position by screwing.
By these means the glass will be securely held from being readily noved off the
supports and without risk of fracture to the glass by excessive local pressure.
But that the Invention may be the better understood I will by the aid of the
accompanying Drawings proceed more fully to describe the same.
DESCRIPTION OF THE DRAWINGS.
Figure 1 shows by side view and Figure 2 by a plan view one of the apparatus
for holding the globes or other glasses used with gas lights, arranged according to
my Invention. a, a, a, represent the three projections or branches or a triangle
forming the support for the globe, the position of which is represented in outline by
the dotted lines in Figure 1. All these supporting branches a, a, a, are formed
with the ordinary outer horns c, c, c, to give external support to the globe, and two
of them are also formed with fixed inner horns d to rise up inside the globe, whilst
to the other bracket c is applied an adjustable horn e which, for facility of appli-
cation or removal of a globe, is capable of turning on the screw sturl f, and, when
set, to bear by its upper end gently on or near the inside of the glass. This
moveable horn e may be set fast by means of the screw stud by simply turning
that stud in the arm a by its head".
By these means the glass globe may be securely held on the brackets or
triangle a, a, a, without fear of its being readily tilted off therefrom, yet so as to
allow of slight play for expansion or contraction of the glass.
Having thus described my Invention and incans which I adopt in carrying
the same into effect, I would have it understood that what I claim is, the arranging
parts of apparatus used with gas or other lights for holding the globes or other
glasses used therewith, substantially as described.
In witness whereof, I, tho said William Bethell Wilkinson, have hercunto set
my hand and seal, this Twelfth (12th) day of August, in the year of our
Lord One thousand eight hundred and eighty.
W. B. WILKINSON.
