I HERBERT DALGETY of 259 Barry Road London, S.E. Inventor and Manufacturer
do hereby declare the nature of my Invention for, A CONSTRUCTION OF CANDLE
HOLDERS TO SHEW ILLUMINATED TIME, to be as follows:-
.
I have one tube turning freely within another, and driven by means of the inner
tube having a slot cut straight down the side, and containing a candle, a guide plate,
and a spiral spring, the outer tube has a raking slot cut spirally round it, and carrys
a Globe or Chimney &c. made of glass or porcelain, or other equally transparent
material, with figures arranged on it to represent hours and minutes, and which are
pointed out by a stationary hand fixed to the inner tube, it will now be seen that as
the candle burns, the spring rises, carrying the guide plate up, and as the guide plate
is formed with a projection, fitting the slots, in both tubes, the result will be, that the
spirally cut tube will revolve, while the inner tube, being fixed to the base of the stand
will remain stationary. The same result will be obtained by fixing the outer tube to
the base of the stand, which will cause the inner one to revolve, and in that case the
stationary hand would be fixed to the outer tube, and the Globe or Chimney to the
inner one.
The figures may be either on the inner or outer side of the Globe or
Chimney.
It is apparent that the spiral spring decreases in power as it opens out, and conse-
quently turns the Globe or Chimney at variable speed, thereby shewing inaccurate
time, but which I over-come by varying the pitch of the spiral slot, and so compensate
for the unequal pressure of the spring, thereby allowing the time to be shewn
accurately enough for all ordinary purposes.
Dated this 9th day of December 1886.

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:
The object of this invention is to construct time indicating spring candle lamps in a
cheap and simple manner. Fig. 1 represents a time indicating spring candle lamp
complete, a, being the spirally grooved pillar fixed to the stand b, c, is the revolving
tube, containing the candle, guide plate d, and spring e, g is the gallery, fixed to the
tube C, and supported and turning on the edge a¹, of the pillar a, and carrying the
shade h, i and are spun up rings, one being formed with a channel round it to take
the hand (which is a piece of wire bent up and flattened and shaped as Fig. 2) by a
frictional grip, allowing said hand to be turned round for setting right, and taken on
and off easily, the gaps in the rings i and ¹ being formed for the purpose of clearing
the projection on the guide plate, Fig. 3.
The following gives a description of the parts separately and their construction, the
letters of reference meaning the same as above.
The pillar a, is made by coiling a piece of sheet metal of the shape of Fig. 4, and
bringing the edges a³, evenly together, which will leave a gap or spiral groove running
down it, in consequence of the rest of the sheet from a', to a², being narrower ; in
order to stiffen and prevent this pillar from springing open, the spun up rings i and i
are placed in position on it and soldered, or otherwise fixed, the edges a³ of the said
pillar are held firmly together by reason of the end of the pillar being inserted and
fixed in the stand b, the revolving tube c, is also coiled up out of sheet metal Fig. 5,
which is so shaped, that when the edges c', are brought together, an opening is left
down the side of the tube, large enough to admit of the candle being placed within,
(see Fig. 5) the end c³, being formed as the nozzle, after placing the spring e, and
guide plate d, (which are fixed together) within the tube, the ears c³ are turned over,
to prevent the spring from coming out, the projection d² on the guide plate traveling
in the slot c. The gallery g, is formed with a central hole g¹, having its edge turned
up to solder or otherwise fix on to the nozzle end of the tube c, thereby fixing the
edges c', securely together, the said gallery also acting as a shoulder to turn on the
top edge a¹, of the pillar a.
Having now particularely described and ascertained the nature of my invention and
in what manner the same is to be performed, I declare that what I claim is :-
1st. The combination of the spiral and straight grooved tubes, substantially as and
for the purposes herin set forth.

page_text: 2nd. In a spring candle lamp, placing the candle in its tube through an opening at
side of said tube, as herin described and shewn in the accompanying drawings.
3rd. In a time indicating spring candle lamp, the stiffening and holding together
rings, i and i¹, having clearance gaps ³, substantially as and for the purposes herin
set forth.
4th. In a time indicating spring candle lamp, the construction of guide plate d, fixed
to spring e, as herin set forth.
5th. In a time indicating spring candle lamp, the frictional grip hand as herin
described.
6th. In a time indicating spring candle lamp supporting the tube c, and accessories,
at a' of pillar a, to allow of their freely revolving as herin set forth.
Dated this 9th day of September 1887.
