OR IMPROVED MEANS OF SECURING LAMPS IN SCONCES OR SOCKETS."
Year: 1880

page_text: LETTERS PATENT to Henry Wallis, of Brighton, in the County of Sussex,
Pianoforte Tuner, for an Invention of "NEW OR IMPROVED MEANS OF
SECURING LAMPS IN SCONCES OR SOCKETS."
PROVISIONAL SPECIFICATION left by the said Henry Wallis at the Office
of the Commissioners of Patents on the 21st January 1880.
HENRY WALLIS, of Brighton, in the County of Sussex, Pianoforte Tuner.
"NEW OR IMPROVED MEANS OF SECURING LAMPS IN SCONCES OR SOCKETS."
The primary object of my Invention is to provide means of fitting and securing
lamps to the ordinary candle sconces of pianofortes, but the Invention is also
applicable to securing lamps to other sconces or sockets. My Invention consists in
making the bottom of the lamp with a stem or piece of suitable form and diameter
to fit securely into the sconce, and in carrying out the Invention I prefer to fit to
the said stem four or other number of springs which stand out at an angle so as to
form a sort of inverted cone, In order to secure the lamp to the sconce the stem
and the springs are pushed down into the sconce, the springs being by this action
forced inwards towards the stem; by their tendency to return to their normal
position they press against the sides of the sconce, and the lamp is thereby
effectually secured.

the said Henry Wallis in the Great Seal Patent Office on the 21st July 1880.

"NEW OR IMPROVED MEANS OF SECURING LAMPS IN SCONCES OR SOCKETS."
The primary object of my Invention is to provide means of fitting and securing
lamps to the ordinary candle sconces of pianofortes, but the Invention is also
applicable to securing lamps to other sconces or sockets. My Invention consists in
making the botton of the lamp with a stem or piece of suitable form and diameter
to fit securely into the sconce, and in carrying out the Invention I prefer to fit to
the said stem three or other number of springs which stand out at an angle so as to
form a sort of inverted cone. In order to secure the lamp to the sconce the stem
and the springs are pushed down into the sconce, the springs being by this action
forced inwards towards the stem; by their tendency to return to their normal
position they press against the sides of the sconce, and the lamp is thereby
effectually secured.
One manner of carrying my Invention into effect is represented in Figure 1 of
the annexed Drawings, which is an elevation partly in section of a lamp; A is the
lamp reservoir which as well as the burner may be of any suitable construction;
B is a stem (either solid or hollow) below the reservoir A; C, C, C, are three
springs rivetted or otherwise fixed at their lower ends to the stem B and standing
out at an angle therefrom, as before explained. When the stem and the springs
are pushed down into a sconce the springs are forced inwards towards the stem,
and by their tendency to return to their normal position they press against the
sides of the sconce and thereby effectually secure the lamp. To enable the lamp to
stand on a table it is provided with a foot D which is open in the middle, so that it
will pass over the outside of the sconce.
Figure 2 represents a slightly different arrangement. The springs C, C, are here
secured at their upper ends to the stem B by means of a ferrule E, and are bent
as shown, so that when pushed down into a sconce they are forced inwards towards
the stem B, and by their tendency to return to their normal position, they press
against the sides of the sconce and thereby secure the lamp. The Figure shows
them in a sconce F. The stem B (Figure 2) is hollow or tubular, and has vertical
slots or openings G in which the springs lie, or partly so when forced inwards;
Figure 3 represents the lamp (Figure 2) as seen from the underside.
And having now described the nature of my said Invention and in what manner
the same is to be performed, I declare that I claim,-
Constructing lamps, substantially as herein before described and shown in the
annexed Drawings, so that they can be secured in a sconce or socket in the manner
explained.
In witness whereof I, the said Henry Wallis, have hereunto set my hand and
seal, this Twentieth day of July, One thousand eight hundred and eighty.
