TRUVIDIONAL DIMUITUATION.
An Improved Globe or Shade Holder for Electric, Gas, or other
Lamps.
I, GEORGE FREDERICK SANDERS of Hockley Street Works Hockley Street,
Birmingham in the County of Warwick, Manufactor, do hereby declare the nature
of this invention to be as follows:-
This invention relates as hereinafter described to an improved holder for holding
or supporting globes or shades of electric, gas, or other similar lamps.
I will describe my invention in reference to a globe or shade of incandescent
electric lamp, the same by slight modification may be applied to any kind of gas or
oil lamp.
In carrying my said invention into practice I make an ornamental metallic dome
shaped top for the lamp terminating in three depending legs, the extremities being.
I also
bent at right angles forming feet for the purpose hereinafter described.
make an ornamental circular shaped metallic cap forming a gallery to fit the top of
the upper flange of the globe and upon the face thereof I depress the metal in
three equal parts forming three trough shaped guides, into each I fit a metal slide
having on the lower face a hook, shaped to clip the outer part of the flange of the
globe, the upper face of each slide I furnish with a projective stud. I provide a
sheet metal ring, which fits loosely the upper part of the metal gallery aforesaid
and is supported thereon by three, or more raised parts of the metal upon which it has
a circular sliding movement, in the said ring I cut three arc shaped slots, into each
engages one of the studs of the slides aforesaid. The slots being placed in such a
position that when the said ring is moved in a circular direction the stud projecting
therethrough will cause the slides to move to and fro riz. to approach or recede from
the centre. I cut three rectangular slots in the ring and over each I place one of the
feet of the depending arms hereinbefore referred to. I connect each of the feet to
the bottom part or base of the gallery aforesaid by screws or other suitable means.
In a convenient part of the gallery 1 cut a longitudinal slot at right angles to
the centre of the moveable ring. I likewise cut a cross slot directly over the
longitudinal slot. I provide a screw box having a projecting stud which passes
through the two slots loosely a swift threaded screw engages in the screw box
and is supported by two projecting ears formed on the gallery the screw being
provided with a milled or other suitable knob which projects outside the holder.
When it is desired to connect a globe to the holder the screw is moved in one
direction which causes the stud of the screw box to slide parallel in the rectangular
slot, the cross slot in the moveable ring will be drawn in an oblique direction, the
ring making a slight circular movement at the same time the three arc shaped
slots press against the studs on the three slides, and cause them to move from the
centre thus widening the space between the hooks. In this position the globe is
held in its place against the holder and the screw moved in the opposite direction
which caused the movement of the parts to be reversed and the slides. to move
towards the centre, the hooks clipping the flange of the globe and securely
connecting it to the holder.

An Improved Globe or Shade Holder for Electric, Gas, or other
Lamps.
I, GEORGE FREDERICK SANDERS of Hockley Street Works, Hockley Street
Birmingham in the County of Warwick, Manufacturer 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 as hereinafter described to an improved holder for holding
or supporting globes or shades of electric, gas, oil or other similar lamps.
I will describe my invention in reference to a globe or shade of an incandescent,
electric lamp; the same by slight modification may be applied to any kind of gas
or oil lamp. In carrying my said invention into practice, I make an ornamental
metallic dome shaped top for the lamp, the bottom edge terminating in a circular
flange. I also make an ornamental circular shaped metallic case forming a gallery
to fit the top of the upper flange of the globe, and upon teach I fit a metal slide
the face thereof, I depress
the metal forming three trough shaped guides.
having on the lower face a hook, shaped to clip the outer part of the flange of the
I provide
globe. The upper face of each slide I furnish with a projecting stud.
a sheet metal ring which fits loosely the upper part of the gallery and is held in
position by the flange of the dome shaped top. The said ring is held in position
by three or more raised parts of the metal forming part of the bottom part of the
gallery about which it has a circular sliding movement. In the said ring I cut
three arc shaped slots aforesaid into each of which engages one of the studs of the
slides. The slots being placed in such a position that when the said ring is moved
in a circular direction the stud projecting there-through will cause the slides to
move to and fro viz. :-to approach or recede from the centre. I connect the flange
of the dome shaped top to the gallery by screws or other suitable means.
In a convenient part of the gallery I cut a radial slot. I likewise cut a cross or
rectangular slot in the movable ring directly over the longitudinal slot aforesaid
and I provide a screw box having a projecting stud which passes through the two
slots loosely. A quick threaded screw engages in the screw box and is supported
by two projecting ears formed on the gallery, the screw being provided with a
milled or other suitable knob which projects outside the holder..
When it is desired to connect a globe to the holder the screw is moved in one
direction which causes the stud of the screw box to slide parallel to the radial slot,
the inclined cross slot in the movable ring will be drawn in an oblique direction,
the ring making a slight circular movement; at the same time the three arc shaped
slots press against the studs on the three slides and cause them to move from the centre
thus widening the space between the hooks. In this position the globe is held in
its place against the holder and the screw moved in the opposite direction to cause
the movement of the parts to be reversed and the slides to move toward the centre,
the hooks clipping the flange of the globe and securely connecting it with the
holder. I may modify the construction and arrangement of the holder to suit the
various conditions of the application of my invention, without departing from
the nature thereof, but I do not claim the right to carry the are shaped slots part
of the way round the circular plate or to use more than one plate.
Figures 1, 2, 3, 4, 5, 6, 7, and 8 illustrate a globe or shade holder made in
accordance with my invention.
Figure 1, represents a globe of an incandescent electric lamp attached to a holder.
Figure 2, represents an elevation of a holder detached from the globe and
Figure 3, a plan.
Figure 4, shows the reverse side of Figure 2 with the top removed showing
the internal arrangement.

page_text: Figure 7 is a cross section on a. b. Figure 4 and Figure 6 is a cross section on c. d.
in the same figure.
Figures 5 and 8 are detailed parts of my invention.
The ornamental top B is connected to the gallery D by means of the flange B'
and the screw pins E. The circular depression D' of the gallery D fits the flange A²
of the globe A. The face of the gallery D is depressed at F F and F³ forming
guides, into each of which is fitted the metal slide G (one being shown separately
at Figure 8) provided with a stud N and the hook H which projects through the
slot I, I or 13 of the gallery D and clips the flange A' of the globe A.
The metal ring J shown separately at Figure 5 rests on the inner surface of the
gallery D, the raised parts K. K. K. projecting through the slots L. L. L. keeping it
in position and limiting the circular movement thereof. The circular movement of the
ring J is effected by the quick threaded screw O which may have four or more threads.
but preferably I use six, is supported by the ears P¹and P and engages in the screw
nut R which carries the stud S. The diagonal slot I, formed in the ring J being placed
over the radial slot U formed in the gallery D the stud S passing there-through.
In Figures 2 and 3 the holder is represented with the slides in their extended
position ready to receive the globe, by rotating the screw O. The screw nut R.
will advance towards the centre and the stud S will slide along the slot U pressing
against the side of the diagonal slot T thus causing the ring J to move in the
direction of the arrow and the slot T into the position shown in dotted lines t
Figure 5. The same movement will also operate the slides G and cause them to
advance towards the centre as shown in dotted lines, g, the arc slots M³, M³, M³,
pressing against the studs N, N, N, thus forcing the slides forward and closing the
hooks H on the flange of the globe as shown in Figure 1 by revolving the screw in
the reverse direction the movable parts are all reversed.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. A holder for holding or suspending a globe or shade by means of the hooked
slides operating and combined with suitable mechanism for opening and closing the
same whereby the top edge of the globe or shade is clipped, or held or released,
substantially as described and illustrated.
2. The globe or shade holder consisting of the metallic ring J having three or
more arc slots M', M³, M', combined and operating in connection with the hooked
slides G and H by means of the studs N substantially as described and illustrated.
3. The combination in a globe or shade holder of the metal ring J like the above
described, the quick threaded screw O, the nut R and the stud S working in the
slots T and adapted to give a circular movement to the ring J all arranged and
operating in the manner described and illustrated.
4. The combination in a globe or shade holder of the metal ring J and the hooked
slides G and H and the gallery D or enclosed casing arranged to operate as
described and illustrated and for the purpose set forth.
5. The improvements in the construction and arrangement of the part of a
globe or shade holder for electric, gas, oil or other lamps co-operating as herein
described and illustrated in Figures 1, 2, 3, 4, 5, 6, 7, and 8 of the drawings and
for the purpose set forth.
