Improvements in Candle Tubes for Carriage Lamps.
.
WILLIAM VINCENT, 76, Castle Street, Reading, Berks, Coach Builder, do hereby
declare the nature of this invention to be as follows:-
My invention consist of improvements in the construction of candle tubes for
carriage lamps and securley affixing candle tubes in the lamp sockets, that the
candle tubes cannott fall out of the lamp sockets. I construct my improved candle
tubes for carriage lamps made with tin brass, or other metal large enough to
admit a candle. I then fix a wire partly round the candle tube some distance down
from the top end. I fix a second piece of wire over the other wire bent at two
angles to form a drop as a recess on candle tube. I then fix a piece of metal
inside of lamp socket the piece of metal bent to the desired shape
required so that when the candle tube is placed inside of the lamp
socket and then turn the candle tube round the wire on candle tube will pass
Over the projecting piece of metal that is fixed on inside of lamp socket
to where the wire is bent at the angles the candle tube then will drop in the recess
between the wires where wire is bent and the candle tube is then held perfectly
secure in the lamp socket so that the candle tube cannott fall out of the lamp socket
when carriage is travelling.

improvements in Candle Tubes for Carriage Lamps.
I, WILLIAM VINCENT, of 76, Castle Street, Reading, in the County of Berkshire,
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 follow-
ing statement:-
:-
My invention relates to the candle tubes of carriage and like lamps and provides
an improved means of securing such tubes in the lamp socket whereby they are
securely locked and prevented from working loose by the jolting or vibration of
the vehicle and so falling out and becoming lost, which is not an infrequent
occurrence with candle tubes retained in the sockets as heretofore.
For the purposes of my invention I provide a bent piece of wire or its equivalent
of peculiar shape soldered or otherwise fastened on the candle tube to form
a lock in combination with a catch or projection on the lamp socket adapted to
engage with the said bent piece of wire, the parts being so arranged that the
candle tube must be lifted and then turned before it can be released from the
Pri QIT

page_text: socket. In some instances the parts may be reversed, that is to say, the catch
or projection may be applied to the candle tube and the bent wire to the lamp
socket.
My invention is illustrated in the accompanying drawing, in which
Figure 1 is a front view of a carriage lamp having my improvement applied
thereto, and
Figure 2 is a section of the lamp socket, and portion of the lamp body looking
from the right in Figure 1, and showing the candle tube in elevation.
Like letters of reference denote corresponding parts in both figures.
A is the lamp body, B is the lamp socket shown supported in a bracket C
in the usual manner, and D is the candle tube. To the side of the tube D
is soldered or otherwise affixed a piece of wire E bent as shown, that is to say,
the said wire is of U-shape arranged on its side, the upper leg of the U being
longer than the other leg and being bent vertically downwards at e as shown leaving
a gap e between said vertical portion and the end of the other leg of the U.
To the lamp socket attached a hook F as shown. The parts are so arranged
that when the candle tube is pushed up into the lamp socket as far as it will
go and then turned in the proper direction the lower leg of the wire E passes
above the hook F and the turning movement is finally stopped by the contact
with the hook of the vertical portion e of the wire. If now the candle tube is
drawn downwards a short distance and then turned in the opposite direction,
the hook F is caused to pass through the gap el and finally is locked in the space
between the upper and lower legs of the wire. The tube can be unlocked and
withdrawn by a reversal of the above movements. It will be obvious that when
the tube is locked as above described it is securely held and cannot be accidentally
unlocked by the jolting or vibration of the vehicle, inasmuch as the tube must be
lifted and then turned before it can be released.
The locking wire may be made of two pieces instead of one as above described,
and the parts may be reversed, that is to say, the hook may be attached to the
candle tube and the bent wire to the lamp socket. In the latter case the bent
wire is inverted so that the gap is at the top.
It is obvious that my invention may be equally well applied to those carriage
lamps in which an oil lamp is used in the tube D in lieu of a candle.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is —
1. In carriage and like lamps means for locking the candle tube in the lamp
socket, said means consisting of a wire or the like and a catch or hook so arranged
that the tube must be lifted and then turned before it can be released, substan-
tially as described.
2. A carriage lamp provided with means for locking the candle tube in the
lamp socket, substantially as described with reference to the accompanying draw-
ing.
