We, ALFRED ERNEST PURROTT, and EDWARD WILLIAM WILLARD, both
of 285, Broad Street, in the City of Birmingham, Manufacturers, do hereby
declare the nature of this invention to be as follows:-
Our invention relates to the manner in which we construct and arrange a
fastening for securing the candle socket in position in a carriage lamp, and also
the method and manner of protecting and guiding the candle socket so as to keep
it from rattling.
Another part of our invention relates to an improved grease cup or protector
which we employ for preventing the overflow of the grease when in use.
In carrying our invention into effect we construct the body and other portions
of our lamp in any well-known manner, with its door, reflectors, and hood arranged
in the ordinary manner to suit the shape of the lamp which is to be constructed.
We form our candle tube with a bead or rim running all round the tube near the
upper end, and having a tapered upper edge which guides it into the socket but
having a square under edge or neck for allowing it to rest upon the retaining or
locking bolt when the same is turned into position.
At the lower part of our candle tube we provide a tapered guiding collar which,
at its greater diameter, just fits the interior of the socket, and we place around the
candle tube at the enlarged end of our tapered guiding collar, a ring or cap, which
projects all round the candle tube, and which forms an annular space between the
outside of the guiding ring and the inside of the collar, into which a projecting
ring or band at the lower end of the socket tube or the socket tube itself can enter,
so that the candle tube is held in position securely and prevented from rattling by
reason of an inside and an outside bearing upon the socket.
We arrange our locking bolt to work upon the bottom of the lamp body, and we
make it of such a form that the end of the bolt passes through an opening or
curved slot formed in the upper end of the socket, the bolt being long enough to
project through, so as to enter under the shoulder formed by the bead upon the
candle tube. We form a handle upon the end of the bolt spindle, and we arrange
a spring plate to press upon the spindle so as to keep it locked under the tension of
the spring, and thus obviate any tendency to work loose. The spring we make in
one simple manner in the form of a plate clipped at each end with the projection
upon the bolt working against it in the centre; the bolt turning in a bearing or
bearings carried from the bottom plate of the lamp body.
We place a hood over the upper end of the candle tube within the lamp body,
and we form this hood with a grease cup or flanged reservoir which projects above
the level of the top of the candle, the cup being formed in such a manner as to
retain the grease, and prevent its escape into the interior of the lamp.
We secure our lamps to the stump in the usual ordinary manner, and we employ
our improved locking device for tubes carrying oil instead of a candle, modifying
the shape of the slot, and the arrangement of the bolt to suit the varying forms of
oil reservoir.
By our improved arrangement of locking bolt we are enabled to raise the candle

page_text: tube into its correct position, should it not be pushed fairly home, before the tube
can be locked.

Improvements in Carriage Lamps.
We, ALFRED ERNEST PURROTT, and EDWARD WILLIAM WILLARD, both
of 285 Broad Street, in the City of Birmingham, Manufacturers, 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 the manner in which we construct and arrange a
fastening for securing the candle socket, barrel, or tube in position within a carriage
lamp, and also the method and manner of protecting and guiding the candle tube
within the lamp socket so as to keep it from rattling.
Another part of our invention relates to an improved grease cup or protector
which we employ for preventing the overflow of the grease when the lamp is
in use.
In the accompanying sheet of explanatory drawings to be hereinafter
referred to-
Figures 1, 2, and 3 are part sectional elevations and Figure 4 a part plan repre-
senting a candle tube secured within the socket of a carriage lamp in accordance
with our invention.
Figure 5 is a part sectional view illustrating our grease cup or protector.
Figure 6 is a part sectional elevation illustrating a modified arrangement of the
candle tube within the lamp socket.
The same reference letters in the different views indicate the same parts.
In carrying our invention into effect we construct the body and other portions of
our lamp in any well-known manner, with its door, reflectors, and hood arranged in
the ordinary manner to suit the shape of the lamp which is to be constructed.
We form our candle tube with a bead or rim as A running all round the tube
near the upper end and having a square under edge or neck for allowing it to
rest upon the retaining or locking bolt B when the same is turned into position.
We also provide on our candle tube a ring or cap such as C, which projects all
round the tube, and forms an annular space into which fits the lower end of the
inner tube C¹ of the lamp socket as illustrated at Figure 3, so that the candle tube
is held in position securely and prevented from rattling by reason of an inside and
an outside bearing upon the socket.
We arrange our locking bolt B to work upon the bottom of the lamp body, and
we make it of such a form that the end of the bolt passes through an opening or
curved slot D formed in the upper end of the socket, the bolt being long enough
to project through, so as to enter under the shoulder formed by the bead upon the
candle tube as illustrated at Figures 2 and 4. We form a handle B' upon the
end of the bolt spindle B2, and we arrange a spring plate such as B³ to press upon
the spindle or the bolt B so as to keep it locked under the tension of the spring,
and thus obviate any tendency to work loose. The bolt turns in a bearing or
bearings carried from the bottom plate of the lamp body.
By our improved arrangement of locking bolt we provide for an automatic

page_text: raising of the candle tube into its correct position on the locking movement of the
bolt in the event of the tube not being pushed fairly home.
We place a hood such as E Figure 4 over the upper end of the candle tube
within the lamp body, and we form this hood with a grease cup or flanged reservoir
as F which projects above the level of the top of the candle the cup being formed
in such a manner as to retain the grease, and prevent its escape into the interior of
the lamp.
We secure our lamps to the stump in the usual ordinary manner, and we employ
our improved locking device for tubes carrying oil instead of a candle, modifying
the shape of the slot, and the arrangement of the bolt to suit the varying forms
of oil reservoir.
In the modified arrangement of the candle tube and socket illustrated at Figure 6
we dispense with the cap C such as hereinbefore described, and provide an aperture
or recess such as A' at the lower end of the lamp socket as illustrated. The
part A of the candle tube or barrel is not rigidly secured to the part A' but
simply fits into the bush or bearing piece A' secured in the interior of the part A³.
The spring A presses down the part A3 and keeps same in position.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is-
1. The improved method of securing a candle or oil tube or like part of a
carriage lamp substantially as described.
2. In carriage lamps, the use of a locking bolt such as B arranged for passing
through an aperture or curved slot D in the socket and under a shoulder or
projection as A from the candle or like tube in such a manner that the locking
movement of the bolt will automatically raise the tube into its correct position in
the event of its not being pushed fairly home, substantially as described and as
illustrated in the drawings.
3. The improved grease cup or protector for a carriage lamp substantially as
described and as illustrated at Figure 5 of the drawings.
4. The improved construction and combination of parts forming the means
whereby a candle tube is held and prevented from rattling within the socket of a
carriage lamp, substantially as described and as illustrated in the drawings.
