PROVISIONAL SPECIFICATION.
Improvements in Globe Holders for Electric and other Lighting
Fittings.
We, ELIJAH ATKINS, and WALTER ATKINS, both of Hall Road, Handsworth,
Staffordshire, Manufacturers, do hereby declare the nature of this invention to be
as follows:-
This invention relates to the construction and arrangement of mechanism
primarily for holding or supporting the globes for electric lighting purposes, but
which may be also applied to the securing or carrying the globes or shades of other
lighting fittings.
Its object is, to provide sliding or lever claws acted upon by springs, so that such
claws may automatically clip the edge or flange of the globe &c., but which said
claws may be compressed towards or from each other (as the case may be) in order
to release the said globe &c.
It consists somewhat as follows:-A metallic ring or framework is provided
suitably arranged, by screwing or otherwise, to the main fitting.
Upon either side of this ring &c., a slot or opening is made through which works
a slide.
We now cut the blanks from a piece of sheet metal having at their front part
two narrow strips forming stems or legs.
At the rear or opposite side are two or more branching out strips, which, when
bent upwards and over form the claws or clips for gripping the globe &c.
At the said rear part is also provided an outstanding strip which forms the slide
to work in the aforesaid slot or opening in the frame or ring, and which terminates
with a pressure knob or button upon its exterior.
Thus, these two parts being placed one upon either side of the frame, the two
legs or stems of the one, cover or rest upon those of the other, and encircling
these double legs, is a spiral wire spring whose tendency is, to open or press them
apart.
Thus it will be seen that, by first compressing the two outstanding pressure
knobs or buttons, the claws are contracted when the globe or shade may be placed
therein, and when letting go, the springs will effectually expand the claws to clip
or sustain the said globe whether in an inverted position or otherwise.
In some cases, these clips may be formed upon a vertical flap or lever, its fulcrum
being carried upon the ring or frame, and the upper part or claws, being pressed
outwards as before by means of a spring, and further furnished with similar
pressure knobs or buttons, so that the said claws may be contracted as before
described.
Or in other cases, these claws may be carried upon horizontally working levers,
having a common or separate fulcrum joint, such parts being kept apart and
operated similarly as before described.

Holders constructed according to this our invention are thus capable of gripping
or holding globes with or without flanges.

We ELIJAH ATKINS, and WALTER ATKINS, both of Hall Road, Handsworth,
Staffordshire, Manufacturers, do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement :-
be
This invention relates to improvements in the construction and arrangement of
mechanism, primarily for holding, or supporting the globes for electriculighting
purposes, but, which may be also, applied to the securing or carrying, of the globes
or shades of other lighting fittings, and in which the said globes or.shades. may.
held at any position, either vertical, angular or inverted; and the object of our
invention is, to provide sliding claws, acted upon by springs, so that, such.claws,
may automatically clip the rim, edge, or flange. of the globe or shade, but which
said claws may be compressed inwards (or outwards as the case. may be) in order
. to release the said globe or shade.
t
We attain these objects by the mechanism illustrated. in: the accompanying
drawings, in which :—

Fig. 1, is a front vertical elevation of the holder as used for a dependent globe.
Fig. 2, is a side view of the holder.
Fig. 3, is an inverted view of the holder.
Fig. 4, is a vertical section of the holder on the line 1-2. (Fig 2).
Fig. 5, is a general view of tlie holder, shown as, supporting a globe.
Figs. 6 & 7, are detailed views of one of.the.claws.
Figs. 8 & 9, are detailed plan. and side views. of the.. tubular, cover. for the
springs.
Fig. 10, is a part sectional view of the .holder. as. applied to an upright globe or
shade.
Fig. 11, is a front; Fig..12, a.plan,..and Fig. 13, a side view of the upright
holder.
.
Fig. 14, is a sectional elevation of the holder.on. the line 3-4. (Fig.12).
Figs. 15 & 16, are side and plan views of the sliding claw (shown in Fig. 12).
Similar letters refer to similar parts. throughout the several views.
We will first describe our invention as it may be applied to, a.down.bauging
globe or shade, and specially applicable. to .electric,light fittings (and having
reference more.particularly to Figures.1 to 9 inclusive).
A, is a metallic ring or framework which is suspended or carried, from the main
fitting or support by screwing or otherwise in any of the ordinary ways. Upon
either side of this frame slots or, openings B,.B, are.made through which. work.the
slides C, C. From a sheet of metal is cut out.the. blank which. by.suitable.bending
and shaping forms in one piece the claws D, D, D, sliding rods E, E, plate-part F,
slides,C, and pressure piece G..
Two of these claw parts are placed in the ring or frame A, the two rods.E, E,
of the one piece lying upon the two rods E, E; of the other piece. (sce. Fig. 4), when
the spiral spring H, is passed over both, the..tendency: of which. is.. to expand
outwards the claws D, D, D. The spring. H, is. again.covered or hidden by means
of the tubular piece 1, having slots J, J, cut therein to permit of the to and fro
motion of the.claw pieces,F, &c.
Referring further to the modified adaptation of this our invention to an upright
globe (and as mores particularly illustrated in Figs. 10 to 16 inclusive) it will be
readily seen that a mere modification in the shape or position of the parts is
necessary, in which A, is the frame or ring having the cross bar K, on which the
claws D, D', are made to slide by means of the turn over pieces M, while the
rods E', E', slide to and fro through eyes N, formed upon the cross bar K, and

page_text: acted upon by the springs H1, H', the pressure pieces G, G³, in this case being
placed upon the underside of the fitting.
The precise shape of the claws D, or D', may be varied to accommodate any
peculiarity in the form of the globe or shade.
Also it will be readily seen that the claws may be arranged to clip externally a
flange upon a globe instead of internally as herein described and illustrated.
Having now particularly described and ascertained the nature of this our inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :-
The combination in globe holders for electric and other lighting fittings of a
ring or frame A, A', having a suitable attachment to the inain fitting, with sliding
claws D, D', rods E, E', pressure parts G, G¹, and operating springs H, H³,
substantially as set forth.
