PROVISIONAL SPECIFICATION.
Time Candlestick.
JOHN HOWARD Ross 30 Crompton Road Handsworth, Birmingham, Lighting
Engineer, do hereby declare the nature of this invention to be as follows:-
The application to a candlestick or candle holder, of a spiral guide or screw in
such a manner that a part which compresses the candle lengthwise either by its own
weight or pushed by a spring, is caused to revolve by having a part which traverses
the spiral guide or screw as it follows the candle in its gradual decrease in
length whilst burning, the revolving of said part causing a globe or dial of
convenient form illuminated by the light and suitably figured to indicate the time,
& carried thereby, or connected thereto, to move past a fixed hand or indicator ;
or the hand or indicator to move past a fixed dial as desired; the figures on globe
or dial representing hours or parts of hours, & the pitch of the spiral guide or
screw being adapted to suit the pre-determined rate of decrease in length of
candle while burning.

COMPLETE SPECIFICATION.
Time Candlestick.
JOHN HOWARD Ross 30 Crompton Road Handsworth Birmingham, Lighting
Engineer, 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 consists in the application to a candlestick or candle holder of a
spiral rod or screw which as it follows the candle-in burning either by its own
weight or assisted by a spring is made to revolve by passing through a suitably
shaped hole which acts as a nut would upon an ordinary screw, the lower end of
the spiral rod or screw has fixed to it suitable connections to a gallery which
carries a suitably figured translucent globe or drum, the gallery which holds the
globe rests upon and is detachably connected to a cap with a hole in the centre
for the flame to pass through and having suitable perforations to admit air to the
flame, this cap rests upon the top or burning end of the candle and follows it as it
burns descending vertically along suitable guides & carries or has attached to it
a hand or indicator which the figures on globe pass as it is revolved by the screw
thus indicating the time. The pitch of the spiral rod or screw is regulated to
suit the predetermined rate of decrease at which the candle burns.
To enable my invention to be more clearly understood I will describe one method
of how it can be carried into practice by reference to the accompanying drawings
in which the same letters stand for the same parts in different figures but it will be
readily understood that the mechanical arrangement of the parts may be altered
and yet come within the scope of this my invention.
In Fig. 1, A is a stamped or suitable base with a socket A' to hold the candle
and guide rods A' connected at top to bridge A in the centre of which is a hole
through which the spiral rod or screw B passes and which causes it to revolve
as it is moved up or down. B is a spiral rod or screw of suitable pitch to the
candle E and having a knob B¹ at top to lift it by, the bottom being centrally
fixed to a disc or tripod B having rods or connections fixed to it and also fixed to
the gallery B upon which the globe B rests loosely. B' is a flange secured to

page_text: the gallery B upon which it revolves and is detachably connected to the cap C.
C is a cap suitably shaped to fit & rest upon the top of the candle E and having
parts C' which slide loosely up & down the guide rods A' and having pieces C* fixed
to it upon which the gallery B with flange B³ rests & revolves, and which has
catches C³ jointed to them in such a manner that the flange B descending will
open the catches & become connected to the cap C by the catches falling in upon
the top of the flange as shown. D is a handle to lift the candlestick by.
Fig. 2 shews a section of rod B in the hole A in centre part of bridge A*..
The candlestick can be operated as follows.
When the candle E is lighted lift the knob B' which lifts the parts B B B³ B
B B and by means of the catches C³ the parts CCC CC, then place the
lighted end of the candle E into the cap C with the flame passing up through the
central hole in cap into the inside of globe 13 and place the lower end of candle in
the socket A' allowing the cap C to descend with the candle & rest upon it when
the candle has burnt a sufficient time to soften the wax & begin to shorten then
turn the globe B round in the gallery B₁ until the figure indicating the correct
time is opposite the hand or indicator C2 then as the candle descends in burning,
the globe as it follows it is caused to revolve by the spiral or screw B and thus
indicate the time.
Having now particularly described and indicated the nature of my said
invention and in what manner it is to be performed I declare that what I
claim is :-
1st. The application to a candlestick or candle holder of a spiral rod or screw
so arranged that it descends freely in a fixed hole or guide attached to the
candlestick which causes it to revolve the figures on a translucent or perforated
globe or dial carried thereby, and surrounding the flame, past a fixed hand or
indicator for the purpose of indicating the time as the candle decreases in length
whilst burning.
.
2nd. The application to a candlestick or candle holder of a hand or indicator
fixed to a cap which rests upon the top of the candle and arranged so as to
descend vertically by means of suitable guides or a suitable guide as it follows
the candle in its decrease in length whilst burning, a gallery resting upon and free
to revolve thereon & detachably connected thereto and operated or made to revolve
by a screwed or spiral rod concentric or central therewith and working in a fixed
hole attached to the candlestick, a perforated or translucent globe or drum resting
upon the said gallery & revolved therewith, so that the figures indicating the time
revolve round the flame of the candle & past the fixed hand or indicator on the cap
as the candle burns shorter.
3rd. In the accompanying drawings, the combination of the parts A A' A² A³ A',
B B B B B B³ B³, Č C¹ C² Cª³ &, or their mechanical equivalents as & for
the purposes herein before described.
