PROVISIONAL SPECIFICATION.
Improvements in Gas, Electric, and other Globe or Shade Holders.
I, CLAUD HAMILTON, of 5, Charing Cross Mansions, Glasgow, Electrical
Engineer, do hereby declare the nature of this invention to be as follows :-
:-
This invention relates to holders for gas, electric or other globes or shades and
it has for its object to improve and simplify the construction of such holders.
My improved holder consists of the usual bracket stem or support which is
screwed at its outer end, on the screwed stem is fitted a screwed collar or nut and
a hollow preferably freely sliding metal or other cup to which latter the glass globe
or shade is secured as hereinafter described. That part of the cup where it is
secured or fitted on the stem or support has pinned, hinged or otherwise suitably
jointed to it at their ends three or other number of bent arms. These arms are
bent inwards or towards the stem and have free movement on the hinges or joints.
The metal of the cup may be stamped or cut out so as to form the hinges or joints
if desired or a metal ring may be inserted in the apex of the cup to which the arms
are pinned or pivotted. There is or may be fitted or screwed on to stem a washer
or collar, or the stem may have a flange or its equivalent. The stem may be solid
or hollow as desired.
With this arrangement, with suspended globes, when it is desired to secure the
globe or shade in place the screwed collar is screwed back so as to allow the cup to
pass up the stem, when this is done the arms hang down slack against the side of
the stem and the glass globe or the shade may be placed in position without
difficulty. To hold the shade or globe securely in position all that is required is to
screw up the collar and so push down the cup. In pushing down the cup the bent
arms catch on the washer and are forced outwards from the stem so gripping and
holding the globe or shade firmly and securely in place.
The invention may be slightly modified to suit different forms of globes or
shades.

COMPLETE SPECIFICATION.
Improvements in Gas, Electric, and other Globe or Shade Holders.
I, CLAUD HAMILTON, of 5, Charing Cross Mansions, Glasgow, Electrical
Engineer, do hereby declare the nature of this invention, and in what manner
the same is to be performed, to be particularly described and ascertained in and
by the following statement :-
This invention relates to holders for gas, electric, or other globes or shades and it
has for its object to improve and simplify the construction of such holders.
My improved holder consists of the usual bracket, stem, pendant, or support
which is screwed at its outer end, on the screwed stem is fitted a screwed collar or
nut and a hollow, preferably freely sliding metal or other cup to which latter the
glass globe or shade is secured as hereinafter described. That part of the cup
where it is secured or fitted on the stem or support has pinned, hinged or otherwise
suitably jointed to it at their ends three or other number of bent arms.
These
arms are bent inwards or towards the stem and have free movement on the hinges
or joints. The metal of the cup may be stamped or cut out so as to form the hinges
or joints if desired or a metal ring may be inserted in the apex of the cup to which
[ Prins fdl

stem a cupped washer or collar, or the stem may have a flange or its equivalent.
The stem may be solid or hollow, as desired.
And in order that my said invention may be properly understood I have hereunto
annexed an explanatory sheet of drawings showing my invention, by way of
illustration, as applied to an incandescent-electric light pendant.
Fig. 1 shows the pendant in elevation.
Fig. 2 is a vertical section of the pendant with globe broken away.
Fig. 3 is a plan view of the cup with arms.
On the drawings, A is the stem which is as usual screw-threaded at A. B is
the screwed nipple and C the metal or other cup against which the glass globe D is
securely held by means of the arms E. Three bent or curved arms are shown as
being used, although any other desired number may be employed. The arms, as
will be seen, are so bent as to come in contact with the bell-mouthed or cupped
collar F which is screwed on to the end of the stem A. The end of the stem may
have, as shown, a small screwed nipple F1 for the reception of the cupped collar F.
G is a screwed collar for tightening up the cup C against the glass globe.
The arms E are hinged or jointed at their extremities H to the interior of the
inverted cup C. To make the hinges the metal of the cup is partly stamped or cut
out and the cut portions are then bent over to a position, preferably at right angles
to the inner surface of the cup. a, b represent the cut out and bent over portions
of the cup and as will be seen the bent pieces which are arranged in pairs have
cach a hole in them so as to form bearings for projections made on or fitted to the
ends of the arms. These projections c form pivots or turning points on which the
arm works as a hinge or joint. The joint or hinge is shown more clearly in the
enlarged detail view at Fig. 4. Instead of having projections on the arms as
hereinbefore described a pin may be passed through the ends of the arms so as to
form the hinge. The cut out parts d form air holes for the ventilation of the
interior of the globe.
With this arrangement, with suspended globes as hereinbefore described, when it
is desired to secure the globe or shade in place the screwed collar G is screwed
back so as to allow the cup C to be passed up the stem A, when this is done the
arms E hang down slack against the side of the stem and the glass globe or the
shade may be placed in position as shown without difficulty. To hold the shade or
globe securely in position all that is required is to screw up the collar and so push
down the cup C. In pushing down the cup the bent arms catch on the cupped
washer, F, and are forced outwards from the stem so gripping and holding the
globe or shade firmly and securely in place.
Although I have only shown my invention as applied to a pendant it can be
adapted in a similar manner to brackets, gasaliers, etc.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is
1. The arms hinged or jointed to the cup C, substantially as hereinbefore
described.
2. The combination with tlre arms hinged or jointed to the cup of a washer or
collar F or its equivalent substantially as hereinbefore set forth.
