Improvements in Carriage or other similar Lamp Handle Fastenings.
I, WILLIAM TUCKER WEBBER, of City Lamp Works, Bishop Street, in the
City of Birmingham, Manufacturer, do hereby declare the nature of this inven-
tion to be as follows:-
This invention relates to improvements in means for securing the handles of
carriage and other similar lamps, and consists as follows;-
Surrounding the upper part of the handle (candle tube) is an enlarged barrel
part, which fits into the tubular socket of the lamp body. In the annular
space formed by this barrel part, is secured a spring catch, whose upper end
protrudes through the wall of the said barrel part, and corresponding with the
position of such protrusion, and in the interior of the aforesaid socket, is an
opening extending for about one third or thereabouts around such socket interior
surface. Hence when the handle is pushed into the socket, the protrusion
yields into the barrel part to permit of its being pushed therein, until it reaches
the opening when it takes thereinto. If, when being pushed in, the protrusion
should happen not to be fair with the opening, the handle may be turned
around until it does fall therein. Further, the face of the said protrusion is
bevilled so that if the handle is turned in the one direction the protrusion, is
forced backward to permit of its being brought into the undisturbed socket
part, when it may be readily withdrawn, while on the other hand if turned in
the opposite direction, the said protrusion will butt up against the side of the
opening, by which the operator will know for certain that it is in its best locked
position.
I may also form upon the lower part of the socket a projection or the like,
and upon the handle some similar mark, to indicate the relative positions of
the protrusion in the handle, and the opening in the socket, to assist if neces-
sary in the insertion or withdrawal of the handle.
In some cases, I may further change the positions of the protrusion and the
opening, by having the former in the socket, and the latter in the handle.

Improvements in Carriage or other similar Lamp Handle Fastenings.
I, WILLIAM TUCKER WEBBER, of City Lamp Works, Bishop Street, in the
City of Birmingham, Manufacturer, do hereby declare the nature of this inven-
[Price Sd.j

page_text: tion, and in what manner the same is to be performed, to be particularly des-
cribed and ascertained in and by the following statement:--
This invention relates to improvements in means for securing the handles of
carriage and other similar lamps, and consists as follows:-
In order to clearly explain this my invention, I have appended hereunto an
illustrative drawing, upon which are figures and numbers of reference, similar
numbers referring through the several views to the same thing or part, and in
which
Fig. 1, is a view of a portion of the handle of a carriage lamp showing the
front view of the spring catch, by which the fastening is effected.
Fig. 2, is a sectional view of the handle--sideways to that of Fig. 1,-showing
again the spring catch.
Figs. 3 and 4, are detail front and plan views of the spring catch.
Fig. 5, is a sectional view of the lower part of the lamp with the handle in-
serted, and showing the spring catch in its locked position.
Fig. 5, is a detail part view of the lower part of the socket showing indicator.
Fig. 6, is a sectional plan view on line A-B Fig. 5.
Fig. 7, is a sectional view of the lower part of the lamp with the handle
inserted, and showing the spring catch in its unlocked position, so that it may
be withdrawn.
Fig. 8, is a sectional plan view on line C-D Fig. 7,
10 is the handle (candle tube) having the enlarged barrel part 11, which fits
into the socket part 12 of the lamp 13. In the annular space 14 formed in
the barrel part, is secured the spring catch 15, whose upper end protrudes
through the wall of the said barrel part, and corresponding with the position of
such protrusion and in the interior of the aforesaid socket, is an opening 16,
extending for one third or thereabouts around such socket interior surface.
Hence when the handle is pushed into the socket as seen in Figs. 5 and 6, the
protrusion yields into the barrel part to permit of its being pushed. therein,
until it reaches the opening 16, when it takes thereinto. If, when being pushed
therein the protrusion should happen not to be fair with the opening, the handle
may be turned around until it does fall therein. Further, the face of the said
protrusion is bevilled so that if the handle is turned in the direction of arrow 17,
the protrusion is forced backward to permit of its being brought into the un-
disturbed socket part, as seen in Figs. 7 and 8, when it may be readily with-
drawn while on the other hand, if turned in the direction of the arrow 18,
the said protrusion will butt up against the side of the opening 16, as seen
in Fig. 6, by which the operator will know for certain that it is in its best
locked position.
I may also form upon the lower part of the socket a cut away part 19, or a
projection or the like, and upon the handle some similar mark, as seen at 20
Fig. 5, to indicate the relative positions of the protrusion in the handle, and the
opening in the socket to assist if necessary in determining the best position for
the insertion or withdrawal of the handle.
In some cases I may further change the positions of the protrusion and the
opening, by having the former in the socket, and the latter in the handle,
which will be readily seen, merely means the reversing of their positions to
that shown.
Having now particularly described and ascertained the nature of this my said
invention, and the manner in which the same is to be performed, I declare that
what I claim is:-
1. In carriage and other similar lamps, the combination with the socket 12,
having opening 16, of the handle 10, with enlarged part 11, having the spring
catch 15 protruding therethrough with its face bevilled vertically and hori
zontally, to permit of its vertical passage into the opening 16, and backwardly

page_text: around the interior of the barrel part 12, but causing a stop in its forward
rotative movement, all substantially as set forth and shown upon the drawings
and for the purposes specified.
2, The modified combination and arrangement according to Claim One, in
which the spring catch 15, is carried in the socket 12, and the opening 16 formed
in the barrel part 11, all otherwise constructed and operating substantially as
set forth, and for the purposes specified.
