PROVISIONAL SPECIFICATION.
Improvements in Shade Holders for Electric and other Lamps.
We, HUGO HIRST Electrical Engineer and WILLIAM EVERETT GIBSON.
Commercial Clerk, both of 71 Queen Victoria Street in the City and County of
London do hereby declare the nature of this invention to be as follows :-
Our invention relates to improvements in shade holders for electrical or other
lamps, and has for its object the ready adjustment of the shade so as to deflect. the
light rays in any required direction.
In carrying our invention into effect we provide the ordinary screw clip and
shield, or any equivalent arrangement for firmly holding the shade, but mount
this upon a ball and socket or universal joint, the tightness of which is capable of
regulation so that the shade when set to any desired angle may be retained until
another adjustment is requisite.
We do not confine ourselves to any particular kind of universal joint, the
essential feature of our said invention being the combination of such a joint with.
a shade and a lamp of any kind, for the purpose herein before stated.

Improvements in Shade Holders for Electric and other Lamps.
We, HUGO HIRST, Electrical Engineer and WILLIAM EVERETT GIBSON
Electrician both of No. 71 Queen Victoria Street, in the City and County of
London, 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 :—
Our invention relates to certain improvements in shade holders for electric and.
other lamps and has for its object the tilting or canting of the shade in any
direction and fixing it in such position so that the rays of light may be diverted as
desired.
In order that our invention may be the better understood, we have appended the
accompanying sheet of drawings in which
Figure 1 is an elevation of the shade holder, and Figure 2 a section of the
moveable part thereof, similar letters of reference being employed in both views.
to indicate corresponding parts.
In carrying our invention into effect we employ a stalk B, carrying a shield H
and lock nut A holding the shade F in position, rigidly affixed to said stalk B..
The lower part of B terminates in a ball or hemisphere C, which is enclosed by a.
cupped fly nut D engaging with the screwed nipple E forming the upper part of
the shade holder G, this being cupped to carry the lower part of the ball or
hemisphere C. It is obvious, referring to Figure 2, that the stalk B, carrying the
shade F may be tilted or canted in any direction when the cupped fly nut D is.

again tightening the nut D. We may interpose a pad of india rubber or other
elastic or resilient material between the nipple E and the ball C so that instead of
slackening and tightening the nut D each time the shade is tilted, the mere
pressure of the hand suffices to effect the movement, and the elasticity of the pad
effects the retention of position:
We may adapt this device to any kind of lamp or lamp holder, modifying the
other parts to conform thereto.
Having now particularly described and ascertained the nature of our said inven-
tion, and the manner in which the same is to be performed, we declare that what we
claim is;
First. In a shade holder for electric or other lamps the combination of a
stalk B carrying a shade F, with a ball C and cupped nut D engaging with a
nipple E substantially as and for the purposes herein set forth and shown by the
appended drawings.
Second. In a shade holder for electric and other lamps the employment of an
interposed pad of resilient or elastic material between the nipple E and ball' C,
substantially as and for the purpose herein described.
