I, FELIX GOODWIN, trading as Wyncott and Son, of 281, Great Colmore Street,
in the City of Birmingham, Manufacturer, do hereby declare the nature of this
invention to be as follows:-
This invention relates to carriage lamps, and particularly to the means for
securing the candle tubes thereof to the sockets or body parts. The objects
of the invention are, first, to provide a simple and efficient connection, and
secondly, means for making the catch self-finding relative to the shoulder with
which it is to be engaged.
In carrying out my invention, I take an ordinary candle tube and provide the
outside circumference of the same, at a suitable distance from its upper end,
with a collar having a semi-circular or pointed swell or extension projecting
from its upper edge and forming a lead to a correspondingly shaped sinking
formed in the front lower edge of the socket with which it is adapted to engage.
The front part of the collar, or that part opposite to the lead has a bar catch
or shoulder, inclined upon its upper side and straight upon its undersides and
enclosed by hanging or confining branches. This bar or shoulder is adapted to
be engaged by the fastening end of a spring catch located within the space coming
between the outer jacket and inner casing of the socket, so that when the upper
end of the detachable candle tube is introduced into the lower end of the socket,
which is held stationary in the lamp iron, as usual, then the point of the lead
passes into the mouth of the recess or sinking and then, when pushed home,
automatically turns the candle tube and brings the nose of the catch into line
with the catch bar when on sliding home the tube, the nose of the catch works
over the inclined edge of the said bar and snaps at the back of it, thus effectually
connecting the one part to the other.
The disengagement of the parts is effected by taking the catch out of engage-
nent with, or clear of, the bar by lifting it outwards by means of the thumb
cting on a suitable extension of the catch arm.

page_text: 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 relates to carriage lamps, and particularly to the means for
securing the candle tubes thereof to the sockets or body parts. The objects
of the invention are, first, to provide a simple and efficient connection, and
secondly, means for making the catch self-finding relative to the shoulder with
which it is to be engaged and to prevent the twisting of the one part within the
other.
Figure 1 of the accompanying drawings represents a carriage lamp provided
with improved means for connecting the candle tube to its socket in accordance
with my invention.
Figure 2 represents, upon an enlarged scale, a complete vertical section of
the said candle tube and socket, showing the arrangement of the catch and the
means for guiding it into engagement with the shoulder of the detachable tube.
Figure 3 is an underside plan of the bottom of a lamp with the candle tube in
position.
Figure 4 represents a similar sectional view as Figure 3 but with the two
parts, viz., the candle tube and the socket disconnected.
Figure 5 is an underside plan of the socket separately and Figure 6 shows a
like view of the detachable candle tube.
Figure 7 represents an elevation with a portion of the socket broken away show-
ing one side of the candle tube in position and Figure 8 shows a similar view of
the two parts separately.
Figure 9 represents a like view but showing the fastening on the socket and
the shoulder on the other side of the candle tube with which it engages, and
Figure 10 is a similar view but showing the tube disconnected from the socket.
The same letters of reference indicate corresponding parts in the several figures
of the drawings.
In carrying out my invention, I take an ordinary candle tube a, and provide
the outside circumference of the same, at a suitable distance from its upper
end, with a collar b, having a semi-circular or pointed swell or extension c.
projecting from its upper edge and forming a lead to a correspondingly shaped
sinking d, formed in the front lower edge e¹, of the socket e, with which it is
adapted to engage.
The front part of the collar, or that part opposite to the lead has a bar catch
or shoulder f, inclined upon its upper side and straight upon its undersides and
enclosed by hanging or confining branches f¹. This bar or shoulder is adapted to
be engaged by the fastening end g¹. of a spring catch g, located within the space
coming between the outer jacket ³, and inner casing, of the socket e, and as
will be seen from the drawings, the shoulder f, and position-finding projection c
on the detachable tube are set in the same positions relative to one another as
the spring catch g, and recess d, of the socket.
It therefore follows that when the upper end of the candle tube a, is introduced
into the lower end of the socket (which is held stationary as usual in the lamp
iron of a vehicle) in a position in which the shoulder upon it is out of line with
the free end of the catch, the projection c, comes against the closed lower edge el,
of the socket; then in order to bring the catch and shoulder into their proper
positions for engagement, the candle tube is rotated and at the same time an
upward pressure is exercised, so that so soon as the projection c, on the one part,
comes under the corresponding recess d, of the other part, the tube is forced
fully home into the socket and by the engagement of the said position-finding
projection with its recess, the catch and shoulder are located in their proper
relative positions for engagement, which takes place automatically by the nose
end of the catch working over the inclined part leading to the shoulder, and
the tube is prevented from rotating within the socket.
The disengagement of the parts is effected by taking the catch out of engage-

page_text: ment with, or clear of, the bar by lifting it outwards by means of the thumb
acting on a suitable extension 98, of the catch arm.
As a converse arrangement the position-finding projection may be formed
upon the bottom edge of the socket and the recess or sinking into which it
engages may be carried by the candle tube.
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
I claim is:
First: In carriage lamps, the employment in connection with a detachable
candle tube secured in position by a catch or fastener, of a position-finder con-
sisting of a projection on the one detachable part, adapted to be engaged with
a corresponding sinking or projection on the other part, substantially as and for
the purpose described and set forth.
Secondly-In carriage lamps, the combination with a socket having a catch
and a recess at its lower end, of a detachable candle tube having a shoulder or
bar adapted to be engaged by the catch, and a position-finding projection adapted
to take into the recess, with the said shoulder or bar and position-finder on the
part being arranged in the same relative positions to one another as the catch
and recess on the other part, substantially as and for the purpose described and
set forth.
