Improvements in Holders for Globes or Shades of Electric, Gas, or
other Lamps.
1.
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 to be as follows:-
This invention relates to the improvements hereinafter described in holders, for
globes or shades, used for electric, gas, or other lamps, whereby such globes or
shades are held or sustained by a clipping device consisting of three or more
claws or clips which take hold of the edge thereof inward, and outward motion
being imparted thereto for the fastening, the former when such globe or shade
have a flange or a turned up edge; and the latter, when the globe or shade have
no flange, or turned up edge, the opening and closing of the claws or clips being
effected in an expeditious manner enables a globe or shade being attached or
detached to the holder instantaneously. In carrying my invention into practice
I make a metallic dome shaped top, the lower edge terminating into a circular
flange which forms a circular, case the sides thereof being furnished with three
short longitudinal slots, at equal distances from each other, the under surface being
furnished with a curved slot some little distance around the circumference, the end
terminating into a stop formed by turning up the metal at right angles. I fit
loosely into the circular case aforesaid, a sheet metal ring provided with three arc
shaped slots, under each slot, that is, between the ring and the bottom of the case
and in each of the longitudinal slots in the side thereof, I place a clip consisting
of a flat rectangular plate having a turned up end in the form of a hook, a stud or
peg projecting from the under side passes through the are shaped slots in the
ring. The slots being placed in such a position that when the said ring is moved
in a circular direction the studs projecting there-through will cause the slides to
move to and fro viz: "to approach or recede from the centre. The .circular
movement of the ring I effect in the following manner :-I cut away a portion of
the ring, near the edge leaving a strip or bar of metal upon which I place a coil
spring, one end abuting against a part of the ring, and the other being attached
to the turned up portion of the circular case, by this arrangement the slides or
clips are extended inward, that is, in a closed position clipping the flange or edge
of the globe or shade. To the circular ring I fix a screw peg or stud projecting
through the curved slot in the circular case hereinbefore; refered to, provided with
a screw knob it will be obvious that by moving the said knob in one direction the
circular ring will move also which movement will open or cause the slides or clips
to move outward thus releasing the globe or shade, and allowing it to be detached
from the holder., When a globe or shade is attached to the holder the knob
aforesaid may be screwed up which will fix or tighten the slides and, prevent them
releasing their grip of the globe or shade. In some cases I may dispense with
the slides and form a clip in such a manner that by the movement of the ring,
the arc shaped slots therein will cause the said clips to move in a semi-circular
direction on a fixed centre.

page_text: 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.

Improvements in Holders for Globes or Shades of 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 to improvements, hereinafter described, in holders of
globes or shades used for electric, gas, or other lamps whereby such globes or
shades are held or sustained by a clipping device consisting of three or more
claws or clips which take hold of the edge thereof inward and outward motion
being imparted thereto for the fastening, the former when such globe or shade has
a flange or a turned up edge, and the latter when the globe or shade has no flange
or turned up edge, the opening and closing of the clips being effected in an
expeditious manner enables a globe or shade being attached or detached to the
holder instantaneously.
In carrying my invention into practice 1 make a metallic top the lower edge
terminating into a circular flange which forms a circular case the sides thereof
being furnished with three or more short longitudinal slots at equal distances from
each other formed by depressing the metal. I fit loosely into the circular case
aforesaid a sheet metal ring provided with three or more arc shaped slots under
each slot, that is, between the ring and the bottom of the case and in each of the
longitudinal slots in the sides thereof I place a clip consisting of a flat rectangular
plate provided with a stud or peg projecting therefrom which passes through the
arc shaped slots in the ring. 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 and recede from the
centre. A metallic ring similiar to the one aforesaid is described in the Specification
of my Letters Patent No. 8343, dated April 27, 1894, is operated by a screw.
arrangement. The circular movement of the ring in the present case I effect, in
the following manner :
I cut away a portion of the said ring near the edge leaving a strip or bar of
metal upon which I place a coil spring, one end butting against a part of the ring,
and the other being attached to the turned up portion of the circular case. By
this arrangement the slides or clips are extended outward, that is in a closed
position, clipping the flange or edge of the globe or shade. To the circular case
I fix a peg or stud projecting through the curved slot in the metallic ring herein-
before referred to. I also fit a peg or stud to the metallic ring near the curved
slot. It will be obvious that by moving the first mentioned knob in the direction
of the other the metal ring will move also which movement will open or cause the
slides or clips to move inward thus releasing the globe or shade, and allowing it to
be detached from the holder.
In some cases I may dispense with the slides and form a clip in such a manner
that by the movement of the ring, of the arc shaped slots therein will cause the
said clips to move in a semi-circular direction on a fixed centre.

page_text: I will now proceed to describe my invention by reference to the accom-
panying drawings the letters of reference indicating similar parts throughout.
Figures 1, 2, 3, 4, and 5 illustrate a globe or shade holder made in accordance
with my invention.
Figure 6 illustrates a detail part of my invention.
Figure 1 represents a shade in vertical section, attached to a holder, and
Figure 2 represents a plau cf the top thereof.
Figure 4 represents the shade and holder in vertical section taken through two
of the clips
a. b.
Figures 5 represent a plan of the under side of the Figures 1 and 4.
The metallic gallery or circular case A (to which may be connected an
ornamental top) is depressed at B, B, B, B, into each depression fits loosely a clip D,
provided with a projecting stud C.
E, is a metallic ring shown separately at Figure 6 provided with arc shaped
slots F, F, F, F, and the slots H, H, and I. K is a bar formed by cutting away
a portion of the metal ring. The ring E is placed in the circular frame A, the
studs C, C, C, C, projecting through the arc slots F, F, F, F. The slots H, H,
form guides through which pass the gas pipes M, M, which support the holder.
To the end of the slot I is fixed a projecting knob N, the knob O being fixed to
the circular frame A, the function of which is to operate the ring in a circular
direction, by pressing one against the other as shown in Figure 3. The bar k is
furnished with a coil spring P, which butts against the ring at R and the pro-
jection S formed on the circular frame by raising a portion of the metal thus
keeping the ring in one position as shown at Figures 1, 2, 4, and 5.
The spring Prests in the recess V formed in the circular ring.
By pressing the knobs N, O, together the circular movement of the ring is
effected which causes the studs to slide along the slots F, F, F, F, and withdraws
the slides D, D, D, D, from their grip of the shade and at the same time
compressing the spring P. On releasing the knobs N, and O, the action of the
spring forces the ring back to its normal position and causes the clips to slide
outwards as shown in Figures 1, 2, 4, and 5. I may attach a second holder to the
gas pipes M, M, below the one above referred to, to carry a globe, but do not
consider it necessary to describe it, it differing in no respects to the one already
referred to.
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. In a holder for holding or suspending a globe or shade by means of slides or
clips operating, and combined with suitable mechanism for opening and closing the
same whereby the top edge of a globe or shade is clipped or held or released
substantially as described and illustrated.
2. The combination in a globe or shade holder of the metallic ring E, the
spring Pand the projecting knobs N and O adapted to give a circular movement
to the ring E for operating the slides or clips C, C, C, C, all arranged and
operating in the manner described and illustrated.
3. The improvements in the construction and arrangements of the parts 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, and 6 of the drawings and for the
purpose set forth.
Dated this 20th day of July 1895.
