Year: 1880

page_text: LETTERS PATENT to Andrew Howat, of Manchester, in the County of
Lancaster, Engineer, for an Invention of "AN IMproved Method OF AND
APPARATUS FOR HOLDING GLASSES, GLOBES, OR SHADES FOR GAS AND OTHER
LIGHTS."
"
PROVISIONAL SPECIFICATION left by the said Andrew Howat at the Office
of the Commissioners of Patents on the 8th May 1880.
ANDREW HOWAT, of Manchester, in the County of Lancaster, Engineer.
AN IMPROVED METHOD OF AND APPARATUS FOR HOLDING GLASSES, GLOBES, OR
SHADES FOR GAS AND OTHER LIGHTS."
My Invention consists in so supporting the globes for covering lights that no
shadow is thrown except where the branch of the chandelier, or the bracket, or
tube supplying the gas or burning fluid passes under the globe.
ร
I make use of a bracket which is fixed to a collar, which collar is screwed on or
below the burner as usual. At the lower part of this bracket is a clip or cross piece,
on which the lower edge of the globe rests. At the upper end of the bracket is
another clip to hold the upper edge of the globe; this clip''is adjustable to fit
various sizes of globes, and works in a slide on the bracket, and is retained' in' its
place by a set screw or otherwise. This bracket may be made to fit either inside
or outside the globe, and it is so adjusted that it does not obstruct the light, and
the slight shadow thrown by it falls upon the branch or tube.

the said Andrew Howat in the Great Seal Patent Office on the 6th November
1880.
ANDREW HOWAT, of Manchester, in the County of Lancaster, Engineer.
"AN IMPROVED METHOD OF AND APPARATUS FOR HOLDING GLASSES, GLOBES, OR
SHADES FOR GAS AND OTHER LIGHTS."
My Invention consists in so supporting the globes for covering lights that no
shadow is thrown except where the branch of the chandelier, or the bracket, or
tube supplying the gas or burning fluid passes under the globe.
I make use of a bracket which is fixed to or slides on a bar fixed to a collar,
which collar is screwed on or below the burner as usual; at the lower part of this
bracket is a clip or cross piece, on which the lower edge of the globe rests. At the
upper end of the bracket is another clip to hold the upper edge of the globe; this
clip is adjustable to fit various sizes of globes, and works in a slot at the upper end
of the bracket, and is retained in its place by a set screw or otherwise. This bracket
may be made to fit either inside or outside the globe, and it is so adjusted that it
does not obstruct the light, and the slight shadow thrown by it falls upon the
branch or tube.
And in order that my Invention may be fully understood and readily carried
into effect, I will describe the accompanying Sheet of Drawings, reference being
had to the Figures and letters marked thereon.
Fig. 1 is an elevation, and Fig. 2 is a plan shewing my improved globe or shade
holder attached to a gas tube. a is a bar, one end of which is annular, and it is
screwed on to a gas tube; b is a bracket, in the lower end of which is a slot so that
it
may slide on a nearer to or further from the burner according to the diameter of
the globe; b is secured on a by the set screw c; at the upper end of b is another
slot, in which slides the shank of the clip d, which holds the upper edge of the
globe, and it may readily be adjusted to take any ordinary size of globe; & is
secured in the requisite position by the set screw e. The gas tube is marked f, and
the globe, which is indicated by dotted lines, is marked g. It will be seen that the
only shadow thrown by the globe holder would rest upon the gas tube, so that the
holder in no way interferes with the light. Instead of fixing the bracket to the
bar a it may be fixed to the tube f.
Having stated the nature of my Invention, and described the manner of
performing the same, I declare that I claim, supporting globes or shades for lights
so that a shadow may be thrown on one side only, and the holder for effecting this
purpose, substantially as shewn and described.
In witness whereof, I, the said Andrew Howat, have hereunto set my hand and
seal, this Fifth day of November, One thousand eight hundred and eighty.
