I HENRY HUGHES of No. 15 Gough Street Birmingham in the County of
Warwick Lamp Manufacturer do hereby declare the nature of this Invention to
be as follows:-
:-
My invention consists of the combinations of parts hereinafter described for
connecting the removable candle tubes of carriage lamps to the bodies of the said
lamps.
According to one of my improvements I connect the removable candle tube to the
body of the lamp by means of an elastic horizontal arm situated on the upperside
of the bottom of the lamp body and under the reflector on the said bottom. The
said horizontal arm is situated near one side of the top of the tubular socket at
the bottom of the lamp body through which socket the upper part of the candle
tube passes.
The middle of the said arm is slightly curved and projects over or
crosses the side of the socket and the said arm is pressed into and maintained in
the position described by a spring. The end of the horizontal arm most distant
from the lamp door is fixed and its opposite or free end is provided with a thumb
plate by which a lateral motion or a motion towards the side of the lamp may be
given to the said arm. When the fastening arm is loosed it is pressed home by
its spring the elasticity of the said arm assisting in taking it back to its normal
position. At the upper part of the candle tube is a conical collar.
When the candle tube is passed up the socket on the underside of the body of the
lamp the conical collar on the candle tube comes in contact with the curved middle
part of the horizontal fastening arm and pushes it aside and compresses its spring.
After the collar has passed the said arm the latter snaps under the said collar and
prevents the return of the candle tube and thereby connects it to the body of the
lamp. In order to disconnect the candle tube from the lamp the spring fastening arm
is pressed aside by acting upon the thumb plate when the said arm is withdrawn from
under the collar on the candle tube and the latter is released and may be disconnected
from the lamp.

page_text: Instead of rigidly connecting the inner end of the horizontal arın to the bottom of
the lamp body it may turn horizontally on a joint and instead of the side motion of
the horizontal arm to and from the top of the socket for fastening and releasing the
candle tube the arm may turn in bearings on the bottom of the lamp body and have
motion through about a quadrant for fastening and releasing the candle tube.
In this modification the rotating arm has a projection at its middle which engages
under the collar on the candle tube and the rotating arm is pressed into its fastening
position by a spring.
The handle end of the fastening arm in the arrangements described may either be
situated within the lamp body or outside the lamp body. In the former case the lamp
door must be opened before the candle tube can be released.

Improvements in Carriage Lamps.
I HENRY HUGHES of No. 15 Gough Street Birmingham in the County of
Warwick Lamp Manufacturer do hereby declare the nature of my Invention and
in what manner the same is to be performed to be particularly described and
ascertained in and by the following statement :-
My invention consists of the combinations of parts herein after described for
connecting the removable candle tubes of carriage lamps to the bodies of the said
lamps.
According to one of my improvements I connect the removable candle tube to the
body of the lamp by means of an elastic horizontal arm situated on the upper side of
the bottom of the lamp body and under the reflector on the said bottom. The said
horizontal arm is situated near one side of the top of the tubular socket at the bottom
of the lamp body through which socket the upper part of the candle tube passes. The
middle of the said arm is slightly curved and projects over or crosses the side of the
socket and the said arm is pressed into and maintained in the position described by a
spring. The end of the horizontal arm most distant from the lamp door is fixed and
its opposite or free end is provided with a thumb plate by which a lateral motion or a
motion towards the side of the lamp may be given to the said arm. When the
fastening arm is loosed it is pressed home by its spring the elasticity of the said arm
assisting in taking it back to its normal position. At the upper part of the candle
tube is a conical collar.
When the candle tube is passed up the socket on the under side of the body of the
lamp the conical collar on the candle tube comes in contact with the curved middle
part of the horizontal fastening arm and pushes it aside and compresses its spring.
After the collar has passed the said arm the latter snaps under the said collar and
prevents the return of the candle tube and thereby connects it to the body of the
lamp. In order to disconnect the candle tube from the lamp the spring fastening arm
is pressed aside by acting upon the thumb plate when the said arm is withdrawn from
under the collar on the candle tube and the latter is released and may be disconnected
from the lamp.
Instead of rigidly connecting the inner end of the horizontal arm to the bottom of
the lamp body it may turn horizontally on a joint and instead of the side motion of
the horizontal arn to and from the top of the socket for fastening and releasing the
candle tube the arm may turn in bearings on the bottom of the lamp body and have
motion through about a quadrant for fastening and releasing the candle tube.
In this modification the middle of the rotating arm engages under the collar on the
candle tube and the said rotating arm is pressed into its fastening position by a
spring.
The handle end of the fastening arm in the arrangements described may either be
situated within the lamp body or outside the lamp body. In the former case the lamp
door must be opened before the candle tube can be released,

page_text: I will now proceed to describe with reference to the accompanying Drawings the
manner in which my invention is to be performed.
Figures 1 and 2 represent elevations taken in planes at right angles to one another
partly in section of a carriage lamp the removable candle tube of which is connected
to the lamp body according to one of the arrangements of any invention Figures 3
and 4 represent plans of the body of the lamp portions being broken away, Figure 3
exhibiting the candle tube fastened and Figure 4 the same unfastened; Figure 5
represents the removable candle tube detached from the lamp.
C
The same letters of reference indicate the same parts in Figures 1, 2, 3, 4 and 5.
a is the removable candle tube passed into the body of the lamp through the tubular
socket 6 on the underside of the lamp: c is the conical collar near the upper part of
the candle tube a: d is the horizontal-arm-by- which the candle tube is fastened in its
place. The said fastening arm & works in the guide loop e fixed on the upper side of the
bottom of the lamp and under the bottom reflector of the lamp, the said arm d turning
on the joint d² on the said bottom of the lamp. The horizontal fastening arm dis
situated near one side of the top of the tubular socket through which the upper part
of the candle tube a passes. The middle of the fastening arm d is slightly curved and
projects over or crosses the side of the socket as represented in Figure 3 the said
arm d being pressed into and maintained in the position Figure 3 by the spring f:
d3 is the handle or thumb plate on the free end of the fastening arm d. The said
handle or thumb-plate d³ is situated within the body of the lamp and by giving a
lateral motion to the said handle or thumb plate in the direction of the arrow Figure 3,
the candle tube can be unfastened.
In order to connect the candle tube a to the lamp the said candle tube is passed up
the socket b. On the conical collar c on the candle tube coming against the curved
middle part of the horizontal fastening arm d the said arm is turned aside and the
spring is compressed. After the collar e has turned aside and passed the said arm d
the latter snaps under the said collar c as represented in Figure 3 and prevents the
return of the candle tube and thereby connects the said candle tube to the body of
the lamp. By pressing the thumb plate d³ in the direction of the arrow Figure 3 the
spring fastening arm d is turned aside and made to take the position represented in
Figure 4. The fastening arm d is thereby withdrawn from under the collar c of the
candle tube and the latter is unfastened and may be withdrawn from the lamp. In
the lamp represented it is necessary to open the door of the lamp before the fastening
arm can be turned aside but the thumb plate of the said arm may be arranged to
project outside the body so that the candle tube may be unfastened without opening
the door of the lamp.
Instead of making the horizontal fastening arm turn on a joint as represented
the fastening arm may be made elastic and rigidly connected at its inner end to
the bottom of the lamp. In this case the elasticity of the said arm assists in taking
it back to and maintaining it in its normal position Figure 3.
Figures 6 and 7 represent partly in elevation and partly in section and Figure 8 in
plan a carriage lamp in which the removable candle tube is fastened to the body of the
lamp by a rotating arm and Figure 9 represents the candle tube detached from the
lamp. In Figures 6 and 8 the candle tube is represented fastened and in Figure 7
the candle tube is withdrawn from the lamp and the rotating arm raised out of
action.
The same letters indicate the same parts in Figures 6, 7, 8 and 9.
a is the removable candle tube; c the conical collar on the said tube and the
socket on the underside of the lamp as before described: g is the rotating fastening
arm having the wedge shaped figure best seen in Figures 6 and 7, the edge of the
wedge shaped arm engaging under the collar c on the candle tube a to fasten the said
candle tube. The fastening arm g has pivots h, h at its ends which pivots turn and
have a slight play in the bearings or eyes i, i fixed on the bottom of the lamp body.
To the middle of the rotating arm ga handle or thumb plate is fixed for working it
a portion of the said handle or thumb-plate projecting outside the body of the lamp.
The rotating arm g is pressed into its fastening position Figures 6 and 8 by the

page_text: spring acting on the handle or thumb plate k. When the candle tube a is introduced
into the lamp through the socket b the collar c strikes against and lifts the fastening
arm g; the latter is thereby turned on its pivots ii and the spring is compressed the
parts taking the positions represented in Figure 7. On the collar c passing the
rotating aring the latter is pressed into its fastening position by the spring 7 and
engaging under the said collar as represented in Figure 6 prevents the candle tube
from being withdrawn from the lamp. By pressing down the handle or thumb plate k
into the position represented in Figure 7 the rotating arm g is lifted from under the
collar c and the candle tube is released and may be removed from the lamp.
Having now particularly described and ascertained the nature of my invention and
the manner in which the same is to be performed I declare that I claim as my
invention of "Improvements in carriage lamps":
:-
First Connecting the removable candle tubes of carriage lamps to the bodies of the
said lamps by means of a spring horizontal jointed arm or an elastic arm of the kinds
described and represented engaging under a collar on the candle tube substantially as
herein before described and illustrated in Figures 1, 2, 3, 4 and 5 of the accompanying
Drawing.
Secondly-Connecting the removable candle tubes of carriage lamps to the bodies
of the said lamps by means of a rotating fastening arm engaging under a collar
on the candle tube the several parts being constructed arranged and acting sub-
stantially as herein before described and illustrated in Figures 6, 7, 8 and 9 of the
accompanying Drawing.
