An Improvement or Improvements in Carriage Lamps.
I ALFRED WINKLEY of Ash Cottage Murdock Road Handsworth in the County of
Stafford Merchant's Buyer do hereby declare the nature of this Invention to be as
follows:-
My invention consists of the construction and combination of parts herein after
described for connecting the removable candle tubes of carriage lamps to and dis-
connecting them from the barrels of the said lamps.
The upper end of the candle tube is contracted in diameter for passing into the
barrel on the bottom of the body of the lamp and at the shoulder between the
contracted part and the lower part of the candle tube a wire collar is fixed the said
collar passing nearly but not quite round the said shoulder. Near the opening left
in the wire collar a slot is made in the candle tube for the spring catch herein after
described to engage with. That side of the slot nearest the opening in the wire collar
is furnished with a stop made by bending at right angles the wire collar for preventing
the rotation of the candle tube excepting in the proper direction.
In the annular space between the inner and outer tubes constituting the barrel of
the lamp a nearly vertical spring catch is arranged the free end of the said catch
being furnished with a shoulder and a thumb plate for lifting it. The spring of the
catch tends to press it inwards that is towards the axis of the barrel and it is necessary
to lift the said catch outwards or from the axis of the barrel to release the said catch
as hereinafter described.
In connecting the candle tube to the barrel of the lamp the contracted end of the
candle tube is introduced into the barrel in such a position that the opening or cut
away part of its wire collar is opposite the spring catch. On pressing home the
candle tube into the barrel it lifts the spring catch and brings its shoulder outside
the wire collar. By now rotating the candle tube the shoulder of the spring catch
engages with the wire collar and on the candle tube making nearly a complete

page_text: rotation the slot in it is brought under the spring catch which snaps into the said slot
and holds the candle tube firmly in its place. The candle tube when so fastened is
incapable either of a horizontal or vertical movement and hence the shaking or
tremulous motion imparted to the lamp by the carriage cannot unfasten the candle
tube. To disconnect the candle tube from the barrel of the lamp it is necessary to
lift the spring catch by its thumb plate out of the slot in which it is engaged and to
give a back or return rotatory motion to the candle tube until the opening in the wire
collar is opposite the spring catch. When in this position the candle tube is
unfastened and can be withdrawn by a sliding motion from the barrel. Instead of
arranging the spring catch vertically it may be arranged horizontally with the same
or nearly the same effect.

COMPLETE SPECIFICATION.
An Improvement or Improvements in Carriage Lamps.
I ALFRED WINKLEY of Ash Cottage Murdock Road Handsworth in the County of
Stafford Merchants Buyer 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 construction and combination of parts herein after
described for connecting the removable candle tubes of carriage lamps to and dis-
connecting them from the barrels of the said lamps.
The upper end of the candle tube is contracted in diameter for passing into the
barrel on the bottom of the body of the lamp and at the shoulder between the con-
tracted part and the lower part of the candle tube a collar is fixed the said collar
passing nearly but not quite round the said shoulder. Opposite the opening left in
the collar a slot is made in the candle tube for the spring catch herein after described
to engage with.
In the annular space between the inner and outer tubes constituting the barrel of
the lamp a nearly vertical spring catch is arranged the free end of the said catch
being furnished with a shoulder and a thumb plate for lifting it The spring of the
catch tends to press it inwards that is towards the axis of the barrel and it is necessary
to lift the said catch outwards or from the axis of the barrel to release the said catch
as hereinafter described,

page_text: In connecting the candle tube to the barrel of the lamp, the contracted end of the
candle tube is introduced into the barrel in such a position that the opening or cut
away part of its collar is opposite the spring catch. On pressing home the candle
tube into the barrel it lifts the spring catch and brings its shoulder outside the collar.
By now rotating the candle tube the shoulder of the spring catch engages with the
collar and on the candle tube making a semi rotation the slot in it is brought under
the spring catch which snaps into the said slot and holds the candle tube firmly in its
place. The candle tube when so fastened is incapable either of a horizontal or vertical
inovement and hence the shaking or tremulous motion imparted to the lamp by the.
carriage cannot unfasten the candle tube. To disconnect the candle tube from the
barrel of the lamp it is necessary to lift the spring catch by its thumb plate out of.
the slot in which it is engaged and to give a back or rotatory motion to the candle tube.
until the opening in the collar is opposite the spring catch. When in this position
the candle tube is unfastened and can be withdrawn by a sliding motion from the
barrel. Instead of arranging the spring catch vertically it may be arranged hori-
zontally with the same or nearly the same effect.
Figure 1 of the accompanying Drawing represents in front elevation a carriage
lamp the candle tube of which is connected to the barrel of the lamp according to my
invention; Figure 2 represents in vertical section the candle tube and barrel con-
nected together and Figure 3 represents the same unfastened and the candle tube
ready to be withdrawn from the barrel; Figures 4 and 5 represent opposite sides and
end elevations of the candle tube detached and Figure 6 represents the spring catch
detached.
The same letters of reference indicate the same parts in the several Figures of the
drawing.
a is the body of the carriage lamp and the barrel on the bottom of the said body.
The removable candle tube is marked c, d the slight contracted part d of which enters
the barrel in the manner represented in Figures 2 and 3; e is the collar on the
candle tube. This collar e may either be made of wire or made solid with the short
tube which is soldered to the candle tube as represented in the drawing. The said
collar e is cut away at fas best seen in Figure 4 and in the short tube e² and opposite
the cut away part in the collar e a slot g is made as best seen in Figure 5;
hh, is the vertical spring catch the greater part of which is situated in the annular
space between the inner and outer tubes constituting the barrel of the lamp. The
upper end of the spring of the spring catch is fixed to the inner tube of the barrel
and the lower inner end of the said spring is furnished with a shoulder 2 for engaging
in the slot in the tube e². The lower end of the said spring is also furnished with
a thumb plate 3 for lifting it. The spring of the catch tends to press it inwards or
towards the axis of the barrel b and it is necessary to lift the finger plate 3 outwards
to release the catch.
In order to connect the candle tube c d to the barrel b, the contracted end d of the
candle tube is introduced into the barrel in such a position that the opening or cut
away part in the collar e is opposite the shoulder of the spring catch. On pressing
the contracted end d of the candle tube into the barrel bit lifts the spring catch into
the position represented in Figure 3 the collar e limiting the upward motion of the
candle tube. The shoulder of the spring catch now rests on the short tube e
carrying the collar e. The candle tube is next turned so as to engage the shoulder ²
of the spring catch under the collar e and on the candle tube making a semi rotation
its slot y is brought opposite the shoulder which shoulder snaps into the said slot g
as represented in Figure 2 and holds the candle tube firmly in its place, the candle
tube being incapable either of a horizontal or vertical movement in the barrel. By
this means the shaking or tremulous motion imparted to the lamp by the carriage
cannot unfasten the candle tube.
For the purpose of disconnecting the candle tube from the barrel the spring
catch is lifted by its thumb plate 3 so as to withdraw the shoulder from the
slot in the short tube 2. The candle tube is now turned in either direction through
a semi rotation. By this motion the cut away part f in the collar e is brought opposite

page_text: the shoulder 2 of the spring catch when the candle tube is unfastened and can bo
withdrawn from the barrel by a sliding motion.
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;
The arrangement or combination of the parts herein before described and illustrated
in the accompanying drawing for connecting the removable candle tubes of carriage
lamps to and disconnecting them from the barrels of the said lamps, that is to say, the
combination of the collar e cut away part and slot g on the candle tube with the
spring catch h, ², h³ on the barrel the said parts operating substantially as described
and illustrated.
