Complete Specification Left, 26th May, 1891-Accepted, 27th June, 1891
PROVISIONAL SPECIFICATION.
Improvements in Candle Lamps.
1, WILLIAM HENRY WILLOUGHBY, of No. 220, Regent Street, in the County
of London, Manufacturer, do hereby declare the nature of this invention to be as
follows:-
My invention relates to improvements in candle lamps, and has more particular
reference to that type of lamp in which the candle tube is made to appear like a
candle by enclosing it in a tube of corresponding colour and shape. The object of
my invention is to provide for the tube being held vertically in the socket
irrespective of the size of the latter.
In carrying the invention into effect, 1 fix fingers to the bottom of the tube,
which fingers may be resilient or not. Their lower ends present suitable surfaces
upon which the taper head of a pin, or screw, adapted to be engaged by the bottom
of the tube, can be brought to bear, after the fingers are in the socket, for the
purpose of expanding them so as to grip the socket firmly and equally all round.
The taper head is brought to bear upon the said surfaces through the tube,
the connection between the latter and the taper head being, preferably, a screw-
threaded one.

COMPLETE SPECIFICATION.
Improvements in Candle Lamps.
I, WILLIAM HENRY WILLOUGHBY, of No. 220, Regent Street, in the County
of London, 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:-
My invention relates to improvements in that type of candle lamp in which the
candle tube is made to appear like a candle by imparting to its outer surface a
colour approximately the same as that of the candle, and consists in improved means
for holding the tube in the socket.
Hitherto candle tubes of the type described above have been provided, at their
lower extremities, with spring fingers arranged concentrically around a continuation
of the axis of the tube and endowed with only a definite resilience. Now, according
to the present invention, I provide a pin adapted to be engaged by the bottom of the
tube, preferably by a nut on the latter and a screw thread on the former. The
screw is provided with a tapered head, and the fingers are doubled, or enlarged
inwards, so that the motion of the said head, for a given distance in either direction,
will expand them more or less, according to the distance through which the head is
moved, for the purpose of providing for the tube being held upright in spite of any
variation in the diameters of the sockets of a chandelier.
In order that my invention, and the means by which the same is to be carried into
practical effect, may be thoroughly understood, I will now describe them in detail,
referring in so doing to the accompanying drawings which are to be taken as part
of this Specification and read therewith.
Fig. 1 is an elevation partly in section of a candle tube fitted with my invention
and shewing the fingers within the socket, but unexpanded.

page_text: Fig.
is an inverted plan of the tube and fingers as they are illustrated in
Fig. 1.
Fig. 3 is an elevation, partly in section, corresponding with Fig. 1, but shewing
the fingers expanded and held against the socket.
A is the candle tube hereinbefore described, and B is the socket in which it must
be held in an upright position.
C is the tube-bottom which is shewn as fast to the tube, but I do not confine
myself on this point.
.
D is a screwed nut fast centrally to the, preferably, inner face of the tube bottom.
E, E are the fingers. Four are shewn, made out of two strips of metal crossed at
right angles and there soldered together; and e, e are the inward enlargements.
These are produced preferably by bending the strips inwards to the outline
illustrated.
F is the screw engaged by the nut D, and f is its tapered head. This head is
shewn as having as many tapered sides as there are enlargements, i.e., as square in
plan; but it may be circular as to plan and must be taper in elevation. The head is
shewn as beneath the enlargement in Fig. 1, and this is the best position for it,
inasmuch as it keeps the fingers up to an antifriction washer interposed between
them and the tube.
I am aware that it has been already proposed to impart the necessary adjustability
to the socket-fitting of a candle tube of the type hereinbefore described, in respect
of the diameter of the socket, by making it of a block of clastic material e.g., india
rubber. However, I wish it to be distinctly understood that I make no general
claim to socket-fittings adjustable in respect of their expansibility, but
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 1
claim is,
1. The combination of spring fingers adapted to be engaged by a tapered surface,
inward extensions, and tapered head of a pin adapted to be moved in either direction,
as set forth.
2. The c:mbination with the bottom end of a candle-tube, of a nut fast thereto, a
pin projecting axially through the said bottom and engaged by the said nut for the
purpose of moving it in either direction, spring fingers, and inward extensions
thereof adapted to be engaged by a tapered head on the said pin, as set forth.
