Arrangements for such Lamps.
We, WALTER HOWES, HALLEWELL ROGERS, WILLIAM BURLEY, aud
WILLIAM HOWES, trading as Howes and Burley, Lamp Manufacturers, Bishop
Street, in the City of Birmingham, do hereby declare the nature of this
invention to be as follows:-
Our invention relates to improvements in candle tubes for carriage lamps, and
its object is to so hold the candle. tube in the lamp socket that the said tube
is firmly held in the lamp socket, and is prevented from rattling or shaking, by
the motion of the carriage, while at the same time any overflow of candle grease
is prevented from fastening the candle tube into the socket, in such manner as
to prevent its easy withdrawal when desired.
Our invention also permits the use of a candle tube capable of containing the
largest size of candle in the smallest lamp body.
Our invention consists in the arrangement of flat springs or spring pieces
around the part of the candle tube which slips into the lamp socket. These
springs or spring pieces are arranged round the circumference of the candle tube,
so placed that when the candle tube is slipped into the socket the outer surfaces
of the springs press against the interior of the sooket and firmly hold the tube
in place without the possibility of, rattling. The springs also allow the candle
tube when it is within the socket to be considerably smaller in diameter than
the socket and so if by any accident candle grease does find its way between
the candle tubo and the socket it cannot fasten the two together.
At
In a lamp fitted with a candle tube arranged and constructed in accordance
with our invention wo profer to make the candle tube, where it enters the
socket, about a quarter of an inch smaller in diameter than the socket.
that position we arrange round the. candle tube four flat bent or bowed springs
fixed to the tube at one end and free at the other end. The said springs or spring
pieces aro disposed equally round the circumference, and the candle tube is attached
by the spring bolt method well known as used by this firm.
Instead of attaching the springs to the candle tube they may be attached to the
interior of the socket.
Our invention also includes a means of aiding the ventilation of carriage
lamps, and this wo accomplish by leaving the space between the candle tube
and the interior of the socket open to the air at its lower position and so we
cause an air current to enter the lamp by way of the said socket and round the
candle tube.
This arrangement admits pure air just round the candle wick where it is most
required and is used to the best advantage.

COMPLETE SPECIFICATION.
Improvements in Candle Tubes for Carriage Lamps, and Ventilating
Arrangements for such Lamps.
We, WALTER HOWES, HALLEWELL ROGERS, WILLIAM BURLEY and
WILLIAM HOWES, trading ae Howes and Burley, Lamp Manufacturers, Bishop
Street, in the City of Birmingham, 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 :-
Our invention relates to improvements in candle tubes for carriage lamps, and
its object is to so hold the candle tube in the lamp socket that the said tube is firmly
held in the lamp socket, and is prevented from rattling or shaking, by the motion
of the carriage, while at the same time any overflow of candle grease is prevented
from fastening the candle tube into the socket, in such inanner as to prevent its easy
withdrawal when desired.
Referring to the accompanying sheet of drawings:-
Figure 1 shows part in section a lamp to which our flat spring method of fastening
the candle tube is applied.
Figuro 2 is a complete section similar to Figure 1 but showing in addition our
means of aiding the ventilation of the lamp.
Figure 3 is an external elevation of the lamp.
Our invention consists in the arrangement of flat springs or spring pieces C
Figures 1 and 2 around the part A' of the candle tube A which slips into the lamp
socket B. These springs or spring pieces C are arranged round a part A' of the
circumference of the candle tube A so placed that when the candle tubo is slipped
into the socket the outer surfaces of the springs press against the interior of the
socket and firmly hold the tube in place without the possibility of rattling.
The springs also allow the candle tube when it is within the socket to be
considerably smaller in diameter than the socket and so if by any accident candle
grease doos find its way between the candle tube and the socket it cannot fasten the
two together.
In a lamp fitted with a candle tube arranged and constructed in accordance with
our invention we prefer to make the candle tube at the portion A' where it enters
the socket B about a quarter of an iuch smaller in diameter than the socket.as
shown at Figures 1 and 2. At that position we arrange round the candle tube four
flat bent or bowed springs C fixed to the tube at one end and free at the other end.
The said springs or spring pieces are disposed equally round the circumferonce, and
the candle tube is attached.
Instead of attaching the springs to the candle tube A they may be attached to
. the interior of the socket B.
:
Qur invention also includes a means of aiding the ventilation of carriage
lamps, and this wo accomplish by leaving the space between the candle tube and
the interior of the socket open to the air at its lower position and so we cause
an air current to enter the lamp by way of the said socket and round the
candle tube.
'
Holes D, admit air to the space D' whence it passes by holes E, into the
space between the candle tube and the socket and so passes into the lamp
ground the flame.
This arrangement admits pure air just round the candle wick where it is most
required and is used to the best advantage.
We prefer to make our improved lamps with the sockets stiffened with metal
bearing bands or rings as shown in Figures 1 and 3, these rings being
preferably of a metal similar to the general mountings upon the lamp. These
bearing bands permit the lamp socket to be in contact within the stump
socket F, at the ends only, and when the lamp is placed within the stump socket

page_text: the tendency to rust in which is common to the usual or ordinary method of
constructing such lamps is obviated and the lamp made capable of ready
withdrawal from the stump F.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that what
we claim is:
1. In carriage lamps, a candle tube of smaller diameter than the socket into
which it enters, the said tube being held firmly in position by flat springs
attached either to the candle tube or to the socket, substantially as and for the
purposes hereinbefore described and illustrated in the accompanying drawings.
2. In carriage lamps, a candle tube of smaller diameter than the socket into
which it enters held in position as claimed in the preceding claim, together
with a socket so arranged that air enters the space between the tube and socket
and entering the lamp round the wick supplies air to the lamp to the best
advantage, substantially as and for the purposes hereinbefore described and
illustrated in the accompanying drawings.
3. In carriage lamps, the construction of the lamp sockets with stiffening bands
or bearing pieces such as 6 61 for permitting the lamp socket to bear within or fit
the stump socket F, at the upper and lower ends only so that easy withdrawal
is possible, and the tendency of ordinary lamps to rust within the stump socket
prevented, substantially as hereinbefore described and as illustrated in Figures 1
and 3 of the accompanying drawings.
