PROVISIONAL SPECIFICATION.
Improved Means for Looking the Candle Tubes of Carriage and
like Lamps.
THOMAS GELLATLY, Tinsmith and Gasfitter, I, Annan Terrace, 19, Wellington
Street, Dundee, do hereby declare the nature of this invention to be as follows:-
An automatic apparatus for fixing and locking in position the candle-sockets
of carriage-lamps and other lamps of similar construction by means of sliding or
pivoted bolts, a pair of which, with semi-circular curves acting against each other,
encircle the candlo-socket beneath a collar fixed at its upper end, said bolts being
actuated by a spring or springs and releasable from the outside of the lamp.
The invention consists accordingly of two sliding bolts or levers each with a
segmental curve 80 placed that when the two levers are brought together the
cirole formed by the two levers will surround the candle-socket immediately
beneath the collar which is fixed at the top of the socket. The lock works in a
fiat case, fixed in the base of the lamp, above the bottom plate, and beneath the
inside copper plated casing.
When the candle socket is pushed up from beneath, the collar passes between
the lovers, bevels facilitating the introduction of the collar.
Immediately after the collar has passed through between the levers, springs
lock the levers together in position, the levers sliding on the bottom of the case.
In one form of the apparatus, in order to release the candle-socket, the finger
plates each forming part of the corresponding lever, are provided. They project
beyond the lamp on either side the frame and both must be pressed simul-
taneously the necessary distance so that the whole circumference of the collar
may be released, and unless this is done the candle socket cannot be withdrawn.
In the second form of the apparatus the levers are constructed to move on pivots,
so that they may be separated by pressure applied to pivoted arms by one
external finger-plate. Locking may be effected by means of lock springs, or by a
spiral spring or two spiral springs.

I, THOMAS GELLATLY, Tinplate Worker, 1, Annan Terrace, 19, Wellington
Street, Dundeo, do hereby declare the nature of this invention and in what manner
[Price 8d1

page_text: the same is to be performed, to be particularly described and ascertained in and
by the following statement:-
1
An automatic apparatus for fixing and locking in position the candle tubes
of carriage lamps & other lamps of similar construction by means of sliding bolts
a pair of which with semi circular or segmental curves acting against each other
and connected with each other by a pivoted lever, enoircle the candle tube beneath
a collar fixed at its upper end, said bolts being actuated by a spring or springs
& releasable from the outside of the lamp. The invention consists accordingly
of two sliding bolts A and B each with a segmental curve and connected with
each other by a pivoted lever C and so placed that when the two bolts are brought
together the circle formed by the two segmental curves of the bolts will surround
the caudle tube D Fig. 1 immediately beneath the collar E Fig. 1 which is fixed
at the top of the tube. The whole apparatus works inside a case F, F, F, F,
fixed in the base of the lamp G between the outside bottom plate, & the base
plate of the inside copper silver plated casing. When the candle tube D Fig. 1
is pushed up from beneath, the collar E Fig. 1 passes between the bolts A and B
bevels H Fig. 2 facilitating the introduction of the collar, immediately after the
collar has passed through between the bolts a spring I or springs lock the bolts
together in position the bolts sliding on. the bottom of the case F. In order to
release the candle tube the finger plate J forming part of bolt B is provided, it
projects to the outside of the lamp, & must be pressed in the necessary distance so
that the whole circumference of the collar may be released. Or two finger plates
may be used, one forming part of bolt A and the other of bolt B.
Fig. 1 gives a plan with candle tube locked in position.
Fig. 2 a reversed plan shewing the underside with bevels II for the introduction
of the collar with candle tube.
Fig. 3 gives the construction of candle tube.
Fig. 4 end elevation of apparatus with candle tube in
Having now particularly described and ascertained the nature of my said in-
vention and in what manner the same is to be performed I declare that what I
claim is:-
(1) The thorough looking in position of the candle tube by the use of two oppos-
ing bolts which grasp the whole circumference of the tube underneath the collar.
(2) The locking apparatus is so constructed, and so inclosed in a case fixed in
the base of the lamp that its working cannot be disturbed.
