PROVISIONAL SPECIFICATION.
Improvements in Carriage Lamps.
We, JAMES NEALE, JAMES HAROLD NEALE, and ROWLAND WARWICK
NEALE of Graham Street, Birmingham, Lamp Manufacturers (trading as James
Neale and Sons) do hereby declare the nature of this invention to be as
follows:-
Our invention consists in an improved means of fastening and releasing the
candle tube in those lamps where the candle tube slides out of the socket.
On the bottom of the lamp body we put a short shaft in bearings. This shaft
has a motion of rotation through a part of a revolution. The shaft is so fixed in
relation to the candle tube as to pass close to one side of the said tube and to
engage under a collar thereon.
The collar reaches about halfway across the diameter of the shaft, and here a
portion of the shaft is cut away sufficient to allow the collar to pass when with-
drawing the candle tube from the lamp. To fasten the candle tube when reinserted
a partial rotation is given to the shaft, thus bringing the uncut portion of the shaft
to engage with the collar. The candle tube is then firmly locked in place.
On the end of the shaft near the door of the lamp is a short lever by which the
shaft is turned.
When the shaft is turned into position to release the candle tube the lever projects
backwards from the lamp and the door of the lamp in shutting will move the said
lever, so turning the shaft and locking the candle tube in place. Hence, if the lamp
be closed the candle tube must be safely locked.

COMPLETE SPECIFICATION.
Improvements in Carriage Lamps.
We, JAMES NEALE, JAMES HAROLD NEALE, and ROWLAND WARWICK
NEALE, of Graham Street, Birmingham, in the County of Warwick, Lamp
Manufacturers (trading as James Neale and Sons) 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 :-
Our invention consists in an improved means of fastening and releasing the
candle tube in those lamps where the candle tube slides out of the socket instead of
being permanently fixed to the lamp.
On the bottom of the lamp body we put a short shaft in bearings. This shaft
has a motion of rotation through a part of a revolution. The shaft is so fixed in
relation to the candle tube as to pass close to one side of the said tube and to
engage under a collar thereon.
The collar reaches about halfway across the diameter of the shaft, and here a
portion of the shaft is cut away, sufficient to allow the collar to pass when
withdrawing the candle tube from the lamp.
To fasten the candle tube when reinserted a partial rotation is given to the shaft,

page_text: thus bringing the uncut portion of the shaft to engage with the collar. The candle
tube is then firmly locked in place.
On the end of the shaft near the door of the lamp is a short lever by which the
shaft is turned.
When the shaft is turned into position to release the candle tube the lever
projects backwards from the lamp and the door of the lamp in shutting will move
the said lever so turning the shaft and locking the candle tube in place.
In the accompanying drawings
Fig. I shews a lamp, partly in section, fitted with our improved means of fastening
and releasing the candle tube.
Fig. II shews the locking device in plan when in position to fasten the candle
tube; and
Fig. III shews the same in plan when in position to release the candle tube.
Fig. IV shews the shaft separately, and
Fig. V the upper part of the candle tube.
The same letters of reference denote the same parts throughout the drawings.
In Fig. IV a a is the shaft having a part cut away at 6; and a short lever cat
right angles to the shaft. At d a neck, is formed in the shaft to prevent end
play.
The shaft a passes under the collar e Fig. V on the candle tube, and is held in
position by the bearings f, f on the bottom plate of the lamp, or on a plate attached
thereto.
In Fig. I the candle tube is fastened in place, the shaft a being in the position
shewn in plan in Fig. II.
To release the candle tube it is necessary to turn the shaft a, by means of the
short lever c, into the position shewn in plan in Fig. III.
The rectangular plate g, h, i, k represents the bottom of the lamp body, and it
will be seen that in Fig. III the lever c projects beyond the line i k of this plate.
This line ik is the back edge of the lamp body to which the door is hinged. Hence
the closing of the door will raise c to the position shewn in Figs. I and II, and so
turn the shaft a into position to fasten the candle tube by the uncut part of the
shaft turning under the collar e of the candle tube.
So long as the door of the lamp is shut the candle tube must be, secure, as the
shaft cannot turn to release it.
To release the candle tube the lamp door is opened and the shaft turned to the
position shewn in Fig. III, when the candle tube can be withdrawn.
On reinserting the candle tube the shaft may be turned by hand to the position
shewn in Fig. II, or by simply closing the door of the lamp.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
1. The shaft a having a short lever c and a cut away part for the purpose of
fastening and releasing the candle tubes of carriage lamps.
2. The combination of the shaft a short lever c and the collar on the candle tube
for fastening the said candle tube in the lamp.
C
3. The combination of the shaft a, and short lever c with the bottom plate of the
lamp, or a plate fixed thereon, in such a position that the closing of the door of the
lamp shall so act in relation to the short lever c as to turn the shaft into position to
fasten the candle tube in place.
