An Improvement in Electric Incandescent Lamp Shade Holders and
the like, and a Device for Use in connection therewith.
I, WILLIAM HENRY BRADLEY, of Queen's Cottage, Southsea, Hants, Captain
(Royal Navy), do hereby declare the nature of this invention to be as follows:-
---
This invention relates to an improvement in electric incandescent lamp shade
holders and the like, also to an improved device for use in connection there-
with, the object being to facilitate the fixing and removal of the shade.
This invention refers more particularly to that class of shade holders wherein
the shade passes over the tubular stem of the lamp-holder and bears at its top
outside edge against a collar or Hange formed thereon, the shade being then
secured in position. by means of an internally screw threaded ring engaging with
the outer sorew threaded periphery of the lamp holder, and by means of which
it is forced tightly against the aforesaid collar or flange, the essential feature
of this invention consisting in providing a tool or appliance whereby the said
ring may be readily turned and for which purpose a slight modification in the
said ring is required.
In carrying my invention into practical effect, the ring is furnished upon its
surface with two slots or recesses formed diametrically opposite, one to the
other, while the tool by means of which it is to be turned consists of a forked
plate mounted in a suitable handle, each prong or arm of the fork having
closely secured against its side in any convenient and suitable manner a spring
arm, the extremity of which is bent slightly away from the arm of the fork
and in such a way that when pressed into the slots or recesses in the ring, it
takes a firm hold or grip therein in such a manner as to allow of the ring being
readily inserted or withdrawn from the narrowest shade, and screwed into
position or removed with the greatest ease.

An Improvement in Electric Incandescent Lamp Shade Holders and
the like, and a Device for Use in connection therewith.
I, WILLIAM HENRY BRADLEY, of Queen's Cottage, Southsea, Hants, Captain
(Royal Navy), do hereby declare the nature of this invention and in what

page_text: manner the same is to be performed, to be particularly described and ascertained
in and by the following statement: —
This invention relates to an improvement in electric incandescent lamp shade
holders and the like, also to an improved device for use in connection there-
with, the object being to facilitate the fixing and removal of the shade.
This invention refers more particularly to that class of shade holders wherein
the shade passes over the tubular stem of the lamp holder and bears at its top
outside edge against a collar or flange formed thereon, the shade being then
secured in position by means of an internally screw threaded ring engaging
with the outer screw threaded periphery of the lamp holder, and by means of
which it is forced tightly against the aforesaid collar or flange, the essential
feature of this invention consisting in providing a tool or appliance whereby
the said ring may be readily turned and for which purpose a slight modification
in the said ring is required.
In carrying my invention into practical effect, the ring is furnished upon its
surface with two slots or recesses formed diametrically opposite one to the
other, while the tool by means of which it is to be turned consists of a forked
plate mounted in a suitable handle, each prong or arm of the fork having
closely secured against its side in any convenient and suitable manner a spring
arm, the extremity of which is a sufficient distance away from the arm of the fork
and in such a way that when pressed into the slots or recesses in the ring, it
takes a firm hold or grip therein in such a manner as to allow of the ring being
readily inserted or withdrawn from the narrowest shade, and screwed into
position or removed with the greatest ease, which is a considerable improve-
ment upon the usual troublesome method of removing the ring with the aid of
the fingers.
In order that my invention may be more fully understood, I will now pro-
ceed to describe same with reference to the accompanying drawings in which:
Fig. 1 is an elevation partly in section of a shade and lamp holder illustrating
the application of this invention.
Fig. 2 is a plan of the ring used for securing the shade in place.
Fig. 3 is a front elevation of the tool used in connection with this invention,
and
Fig. 4 is a side view thereof.
Fig. 5 is a view illustrating a slightly modified form of construction.
As shown in the drawings, the ring a, by means of which the shade 6 is held
tightly against the collar or flange c, screws on to the lamp holder d and is
furnished upon its under surface with two slots e e arranged diametrically oppo-
site as shown, while the tool for turning this ring for securing the shade 6 in
position consists, as shown in Figs. 3 and 4, of a forked plate f, mounted in a
suitable handle h, while against this forked plate of the tool a second forked
spring plate g is secured by means of a screw k or in any other convenient and
suitable manner, the arms of the spring plate covering the forked extremities
of the tool, the ends of these said arms of the spring plate g being a sufficient
distance away from the plate f as shown (Fig. 4) and in such a manner that
when pressed into the slots or recesses e e of the ring a it takes a firm hold or
grip therein and allow of the ring being readily inserted or withdrawn from
the narrowest shade and screwed in position or removed with the greatest ease.
In the modified form shown in Fig. 5 each of the arms of the forked plate f
is covered by a separate spring arm g' instead of a forked spring plate being
used for this purpose.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is:
-
1/. In a lamp and lampshade holder, the furnishing of a locking ring or collar
such as a with slots such as e, in combination with a tool comprising a forked

page_text: plate such as having a forked covering spring plate such as g, the whole com-
bined, arranged and operated substantially as herein described and shown and
for the purposes specified.
2. In a lamp and lamp shade holder, the furnishing of a locking ring or collar
such as a, with slots or recesses such as e, substantially as and for the purposes
described.
3. The new or improved tool consisting essentially of a forked plate such
as with a forked covering spring plate such as 9, substantially as herein
described and shown with reference to Figs. 3 and 4 of the accompanying
drawings and for the purposes specified.
-
4. The modified form of tool substantially as described and shown with
reference to Fig. 5 of the accompanying drawings.
