Improvements relating to Carriage Lamps.
:-
I, WILLIAM WHISTON, of 5, Great Charles Street, in the City of Birmingham,
Manufacturer, do hereby declare the nature of this invention to be as follows:-
This invention consists of improvements relating to carriage lamps, my object
being to provide for the insertion and retention of the candle within the handle
or holder from the interior of the lamp body, thus enabling a rigid and permanent
attachment to be formed between such handle or holder part and the lamp body.
In the application of my invention in one manner, I employ an ordinary candle
spring within the handle or holder part of the lamp for the purpose of keeping
the candle pressed into the cap or nozzle in the interior of the lamp body. Between
the upper end of the spring and the base of the candle I preferably internose an
elevating stem provided at its outer end with a head or flange to serve as a support
for the candle, and at its inner end with a larger flange which on its engage-
ment with an internal projection at the upper end of the handle, serves as a
stop to limit the upward movement of the elevating stem under the action of the
spring. The candle cap or nozzle within the interior of the lamp body is detach-
ably connected with the base of such body part by a projecting flange having
apertures formed through it for engaging studs secured to the base. At one end
the said flange apertures are sufficiently large to allow the heads of the studs to
pass right through the flange, but on slightly turning or revolving the cap such
enlarged ends of the slots are moved away from the studs, and by the action
of the candle spring the flange is forced tightly against the underside of the stud
heads and the complete cap is thus secured in position.
To detach the cap the lamp door is opened and the cap depressed slightly
against the action of the spring it is then turned or revolved until the enlarged
ends of the flange apertures are brought immediately under the stud heads, when
the cap can be withdrawn.
The candle to be fixed in the lamp has the detached cap passed over its upper
end, and the base of the candle is then placed on the upper flange of the candle
elevating stem projecting into the lamp body. The stem is then depressed,
against the action of the spring, until the enlarged ends of the flange apertures
have been passed over the retaining studs, when the cap is turned or revolved
to move the enlarged ends of the apertures away from the studs as hereinbefore
described.
Instead of securing the cap or nozzle by the engagement of a slotted flange with
studs as herein before described, I sometimes employ but a single projection from
the cap which is caused to pass under a catch plate, formed beneath the base
of the lamp body, and to engage with a slot or aperture formed therein; and I

cap or nozzle to meet varying requirements.

I, WILLIAM WHISTON, of 5, Great Charles Street, in the City of Birmingham,
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 statement:-
-
This invention consists of improvements relating to carriage lamps, my object
being to provide for the ready and convenient insertion and retention of "the
candle or oil or spirit burner within the handle or holder from the interior of
the lamp body, thus enabling a rigid and permanent attachment to be formed
between such handle or holder part and the body part.
In the application of my invention in one manner, employ an ordinary candle
spring within the handle or holder part of the lamp for the purpose of keeping
the candle pressed into the cap or nozzle in the interior of the lamp body. Between
the upper end of the spring and the base of the candle I preferable interpose an
elevating stem provided at its outer end with a head or flange to serve as a support
for the candle, and at its inner end with a larger flange which on its engage-
ment with an internal projection at the upper end of the handle, serves as a
stop to limit the upward movement of the elevating stem under the action of the
spring. The candle cap or nozzle within the interior of the lamp body is detach-
ably connected with the base of such body part by a projecting flange having
apertures formed through it for engaging studs secured to the base. At one end
the said flange apertures are sufficiently large to allow the heads of the studs to
pass right through the flange, but on slightly turning or revolving the cap such
enlarged ends of the slots are moved away from the studs, and by the action
of the candle spring the flange is forced tightly against the underside of the stud
heads and the complete cap is thus secured in position.
To detach the cap the lamp door is opened and the cap depressed slightly
against the action of the spring; it is then turned or revolved until the enlarged
ends of the flange apertures are brought immediately under the stud heads, when
the cap can be withdrawn.
The candle to be fixed in the lamp has the detached cap passed over its upper
end, and the base of the candle is then placed on the upper flange of the candle
elevating stem projecting into the lamp body. The stem is then depressed,
against the action of the spring, until the enlarged ends of the flange apertures
have been passed over the retaining studs, when the cap is turned or revolved
to move the enlarged ends of the apertures away from the stud as herein before
described.
Instead of securing the cap or nozzle by the engagement of a slotted flange with
studs as hereinbefore described, I sometimes employ but a single projection from
the cap which is caused to pass under a catch plate, formed beneath the base
of the lamp body, and to engage with a slot or aperture formed therein; and I

page_text: make other modifications in the fastening or fastenings for my detachable candle
cap or nozzle to meet varying requirements.
Referring to the two accompanying sheets of explanatory drawings.-
Figure 1 on Sheet 1 is a side elevation, with part in section, of a carriage lamp
having my invention applied thereto, the upper part of the lamp body being
indicated by dotted lines.
Figure 2 is a plan of the candle cap or nozzle, and Figure 3 an elevation of
the catch piece with which the said cap or nozzle engages.
On Sheet 2, Figure 4 is a sectional elevation representing a modified form of
connection between the candle cap or nozzle and the base of the lamp body;
Figure 5 is a plan of the candle cap or nozzle shown in elevation at Figure 4.
whilst Figure 6 is a separate view, in elevation, of the stud or catch piece with
which the said cap or nozzle engages.
The same reference letters in the different views indicate the same parts.
The handle or holder A (Figure 1) is rigidly and permanently secured with the
socket B formed with the lamp body, such handle or holder having within it the
spring C and elevating stem D. The candle cap or nozzle E, which is inserted
in its position within the handle or holder A from the interior of the lamp body,
is provided with a flange as E¹ slotted as at e and e¹. The slot e is sufficiently
large to pass over the hook like catch piece F secured to the base of the lamp
body, but the slot or aperture el is only sufficiently large to pass on to or engage
the point or free end of the hook F, being kept in such engagement by the
pressure of the spring C upon the flange E¹.
With the handle or holder A as shown at Figure 4 the elevating stem is
replaced by the tube G and the upper and closed end of which forms the base or
support for the candle H, and instead of the hook like catch hereinbefore described
I have shown a stud as J which I sometimes employ with a candle cap or nozzle E
having a flange 2 perforated as shown at Figure 5, the end e² of such perforation
being sufficiently large to pass over the head or flange of the said 'stud or projec-
tion which is secured to the base of the lamp body.
When the lamp is required to burn oil or spirit I substitute for the candle an
ordinary oil or spirit burner having an ordinary tank or reservoir to fit within
the upper end of the handle or holder A, and provided with a perforated flange
to engage with a catch hook, stud, or projection from the lamp base, as herein-
before described. .
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 {
claim is:-
1. The improvements relating to carriage lamps, whereby the candle or oil or
spirit burner can be inserted and secured within the handle or holder from the.
interior of the lamp body, substantially as described.
2. In carriage lamps, the use of a candle cap or socket or an oil or spirit burner
arranged for engagement and disengagement with the base of the lamp body,
substantially as described.
3. In carriage lamps, the combination comprising a handle or holder part in
permanent attachment with the lamp body part, and a candle cap or nozzle or
an oil or spirit burner in detachable connection with the interior of the said body
part, substantially as described.
