Improvements in or relating to Candle Holders and the like.
1, ALPHONSE MARO PHALEMPIN of 206 Boulevard Voltaire, Paris in the Republic
of France, 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 description :-
The present invention has for its object the construction of a candle-holder or other
lighting apparatus in which candles are used, in which the candle is caused gradually
to rise in a tube as it is consumed, by a spiral spring wound upon a fixed pin secured
in the movable candle-socket. This spring is preferably a compensated one so as to
press the candle upward in a uniform manner in spite of the weight of the candle
diminishing owing to its combustion.
In the accompanying drawing
―
Figure 1 is a sectional olevation of the candle holder with its spiral spring according
to the present invention.
Figure 2 is a horizontal section on the line 1-2 of Figure 1.
Figures 3, 4 and 5 are detail-views.
Figures 6 and 7 are respectively a sectional elevation and a front-view of two
modified constructions of the candle-holder and
Figure 8 is a horizontal section on the line 3-4 of Figure 6.
The candle-holder according to the present invention comprises a tube a in the
interior of which are formed two parallel grooves a al arranged diametrically
opposite each other and extending throughout nearly the whole length of the tube.
The tubo a is provided at the top with two inwardly projecting lips or flanges a³ ³
adapted to engage with the circular groove of an abutment or cap b which is
connected to the tube by a bayonet or other joint. For this reason the cap bis
provided at the sides with two grooves bb diametrically opposite each other, the
lips a' a' engaging with them in order to allow them to engage in the groove 61
when the cap is put in placo. Inwardly extending points or projections ce in
this cap limit the rise of the candle d caused by the spring as will be hereinafter
explained.
The candle is placed with its lower end in a socket e consisting of two parts:
the upper cylindrical part having the shape of a small cup in which is placed the
lower end of the candle, the lower part is preferably of somewhat oblong section having
curved ends (Figure 2) and is provided with a fixed pin on which a spiral spring h
is wound, one ond of the spring being attached to the tube a near the top of the
grooves a' a' in which it lies when stretched.
The curved ends of the lower part of the socket e are guided in the grooves a
Bo that it cannot turn and exercise torsional strain on the portion of the spring h
which is outside the socket.
In order to introduce the candle into the holder, the cap b is removed. Then the
candled is placed into the cup of the socket e, and the cap bis placed on the other
end of the candle. The cap is then pressed down till the socket has been lowered
down far enough until the joint of the cap with the upper end of the tube a can be
affected as has been explained before.
During the descent of the socket the spring becomes compressed on the
fixed pin, and its end passes out of the socket e and lies in one of the grooves a'.
But this part constantly tonds to return to its normal position and re-enter the sockete,

page_text: and therefore exercises on the latter a pull which causes it to rise as the candle is
consumed, which is thus constantly prossed against the points c c of the cap b.
During this rising, the tension of the springh becomes gradually smaller, if the
cross-section of the spring be the same throughout its length, and in such case it
must be strong enough to be able to raiso the candle to the top of the holder. But to
be able to do this it might be a little too strong at first, and might force out the
softened part of the candle at the commencement of combustion. To obviate this.
drawback I preferably use a compensated spring, the cross-section of which
increases from the point of attachment to the tube to the point of attachment to the
pin so that its action becomes less as the weight of the candle decreases and the
latter is constantly pressed against the points c c with equal force.
The cap is provided at the top with a circular collar or flange 18 destined
to rest on the upper edge of the tube in order to retain the candlo-holder
in place.
.
As the candle does not extend quite to the edge of the cap, it cannot melt and
run down the outside of the tube, and as it fits into this cap very exactly the
melted wax cannot run down the interior of the tube.
In the two modifications shown in Figures 6, 7, and 8 the tube a is laterally open
throughout a large part of its length, so that the section of the tubo at the open
portion is a little more than half its circumference, the opening being in any case
sufficient to enable a candle to be introduced into tho tube.
The cap b instead of being removably connected to the tube a is rigidly secured
to it and has points oc to retain the candle. The socket e engages with the lower
end of the tube a and cannot come out through the lateral opening in this tube as
the width of the opening is smaller than the inner diametor of the tube or the outer
diameter of the socket e. On the fixed pin to which the spiral spring his attached,
is mounted a plate i held by a pin and rosting with its vertical edges on those of the
lateral opening in the tube a, thus proventing the socket from rotating and
consequently the spring from being subjected to torsion.
This arrangement avoids the use of the guide-grooves a¹ a' (Figures 1 and 2)
and the lateral opening in the tube facilitates cleaning of the interior of the
apparatus.
In Figure 6 the cap b has not any outer flunge as in Figures 1 and 7, but the
tube a is provided at the bottom with a shoulder m. This arrangement enables
the tube a to be covered with a glass, porcelain or similar tube, resting on said
shoulder, to give the appearance of a candle and completely hide the mechanism
from view. Under the shoulder m on the tube a are attached rubber-plates or
rings n m which ensures the engagement of the device in the candelabra,
candle-stick etc.
In Figure 7 the cap 6 has an outer flange adapted to rest on the upper edge.
of the tube.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed 1 declare that what I
claim is :-
1. A candle-holder constituted by an outer tube and a socket to receive the end
of the candle, said socket being placed and suitably guided in the interior of the tube
and constantly drawn upwards by a spiral, preferably compensated, spring as h,
tending to raise the socket and the candle and keep the latter pressed against a fixed
cap secured to the upper end of the outer tube substantially as described.
2. Jn.a candle holder of the character described, a caudle-socket e acted upon by
a spiral spring hattached at one end to the outer tube a and at the other end to a
fixed pin in said socket, said spring cansing the socket to rise as the candle is consumed,
the socket being guided in grooves or guide-ways, in the tube a, and a cap as b,
serving to retain the candle during its ascent and connected to the top of the tube a'by
a bayonet or other joint, substantially as described.
3. In a candle holder of the character described the combination of an outer tube a

page_text: provided with lateral openings to enable a candle to be introduced, a socket e for the
latter acted upon by a spiral spring and having a diameter greater than
the width of the opening in the tube, and a plate i upon said socket substantially as
described.
4. In a candle holder of tho character described the arrangement at the lower end
of the tube a of rubber plates for ensuring the rigidity of the holder in its support,.
substantially as described.
5. The combination and arrangement of parts constituting the complete candle.
bolder substantially as described and illustrated in Figures 1, 2, 3, 4, and 5, or in.
Figures 6, 7 and 8 of the accompanying drawings.
