page_text: 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 simple and effective means for the attachment of the handle or
like part to the socket or to the base of the lamp, and of the nozzle to the upper
end of such handle part.
In the application of my invention to carriage lamp provided with the
ordinary socket which is inserted within the lamp iron, I secure on the exterior
surface of the upper end of the tubular handle or like part a ribbed tube for
fitting within the lamp socket. Upon the lower end of the socket or receiving
tube I secure an engaging or locking piece having its hook like end projecting
below the extremity of the socket, and in a corresponding position upon the
handle part I secure a combined stop and locking peg or lug for engagement
with the said hooked locking piece. The handle part can be inserted within
the socket in any position but the combined stop and locking peg prevents it
from entering too far within the socket. After being pushed into the socket to
the full extent permitted by the lug the handle part is turned round and pulled
down until it is caused to engage with the hooked locking piece, and by such
engagement the two parts are effectually secured or locked in position. I am
thus enabled to prevent the handle part becoming lost or detached from the
lamp by the jarring of the vehicle when in motion, a result very common in the
ordinary method now in use of attaching the handle part to the lamp.
The external ribs on the tube secured to the upper end of the handle part as
herein before described form corresponding recesses in the interior of the tube,
and one of such recesses I employ as a guiding groove for the attachment lug
secured upon the body part of the nozzle, or upon the upper part of the candle
tube or handle part. On pushing the nozzle to its innermost position and on
slightly turning it within the ribbed tube the attachment lug is made to ascend
a spiral aperture formed around a portion of the tube, and the nozzle and the
tube are thereby secured together.
The handle part having the nozzle in combination with it can be removed
from or attached to the lamp, or the nozzle can be removed and attached whilst
the handle remains in combination with the lamp.

page_text: Improvements i craving
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 simple and effective means for the attachment of the handle or
like part to the socket or to the base of the lamp, and of the nozzle to the upper
end of such handle part.
On the accompanying sheet of explanatory drawings to be hereinafter
referred to,
Figure 1 is an elevation and Figure 2 a sectional plan representing the nozzle
and the handle part of a carriage lamp attached or connected together in accord-
ance with my invention.
Figure 3 is an elevation of a handle part for attachment to a carriage lamp
in which the nozzle is formed with the base part of the lamp body.
Figure 4 is an elevation, with part in section, representing the handle part
locked in position within the lamp socket.
Figure 5 is an elevation showing the inner or receiving tube of the lamp
socket but not the outer part of the same, and with the handle inserted therein
but not locked in position as in Figure 4.
The same reference letters in the different views indicate the same parts.
In the application of my invention to a carriage lamp provided with the
ordinary socket as A which is inserted within the lamp iron, I secure on the
exterior surface of the upper end of the tubular handle or like part B a ribbed
tube 31 for fitting within the inner or receiving tube A' of the lamp socket A.
Upon the lower end of the socket or receiving tube I secure an engaging or
locking piece Chaving its hook-like end projecting slightly below the extremity
of the socket, and in a corresponding position upon the handle part I secure a
combined stop and locking peg or lug D for engagement with the said hooked
locking piece. The handle part can be inserted within the socket in any position
but the combined stop and locking peg D prevents it from entering too far within
the socket. After being pushed into the socket to the full extent permitted by
the lug, (as indicated at Figure 5), the handle part is turned round and pulled
lown until it is caused to engage with the hooked locking piece C, and by such
engagement the two parts are effectually secured or locked in position.
thus enabled to prevent the handle part becoming lost or detached from the lamp
by the jarring of the vehicle when in motion, a result very common in the ordi-
nary methods now in use of attaching the handle part to the lamp. As an addi-
tional security I preferably employ a spring guard or lock as E which is forced
aside when turning the handle into position or withdrawing it therefrom by the
rounded face on the upper part of the peg or lug D, but which by abutting
against the said peg or lug D as shown at Figure 4 prevents accidental move-
ment or rotation of the handle away from the locking piece C, when it may not,
through inadvertence, have been drawn into proper engagement with the lower
or hooked part of the said locking piece.
I am
The external ribs as b on the tube B' secured to the upper end of the handle
part B as hereinbefore described, form corresponding recesses in the interior of
the tube, and one of such recesses I employ as a guiding groove for the attach-
ment lug secured upon the body part of the nozzle F. On pushing the nozzle
to its innermost position and on slightly turning it within the ribbed tube the

page_text: attachment lug is made to ascend a spiral slot or aperture formed around a portion
of the tube, and the nozzle and the tube are thereby secured together, as illus-
trated at Figures 1 and 2.
The handle part having the nozzle in combination with it can be removed
from or attached to the lamp, or the nozzle can be removed and attached whilst
the handle socket remains in combination with the lamp.
In a handle part for attachment to a lamp having the nozzle formed with the
base of its body part, I secure a plain candle-tube as B2 (Figure 3) to the upper
part of the handle tube B instead of the ribbed tube 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
I claim is:-
1
1. In carriage lamps, means for the attachment of the handle or like part to
the lamp socket, and of the nozzle to the upper end of the said handle or like
part, substantially as described and as illustrated.
2. In carriage lamps, the combination with a handle part having a ribbed
and slotted portion as 13 at its upper end, of a nozzle part as F having a lug or
projection as f substantially as and for the purpose described and as illustrated.
3. In carriage lamps, the arrangement and combination respectively with the
socket and with the handle, of parts whereby the said handle can be readily and
effectually secured or locked in position within the said socket, substantially as
described and as illustrated.
