PROVISIONAL SPECIFICATION.
Improvements in Mechanism for the Securing of the Candle Tubes
to Carriage or other similar Lamps.
I WILLIAM TUCKER WEBBER, of The Birmingham Carriage Lamp Works,
Bishop Street, in the City of Birmingham, Manufacturer, do hereby declare the
nature of this invention to be as follows:-
This invention relates to improvements in mechanism for securing the candle
tubes of carriage or other similar lamps to the bodies of such lamps.
It consists as follows:-Upon the exterior of the upper end of the candle tube
are made one, two, three or more all around collars, rings or beads, at any
desirable distance from each other along the said tube, as may be required or
desired according to fastenings hereinafter stated. The particular sectional shape
of these rings &c. may be varied to suit the requirements of those fastenings, or
similar to, those hereinafter mentioned.
Within the bottom part of the lamp body or upper part of the socket, a spring
Catch, lever or bolt, or similar device is so arranged so that when the candle tube
is pushed up, even but a small distance, the first or more of the rings or beads shall
have passed or pushed its way by the catch or bolt so that the latter may pass
back underneath the ring, collar or bead, so that the tube cannot fall therefrom.
When properly pushed home the said catch or bolt would pass underneath the
lowest of such collars &c.
If desired one or more of such collars or rings may be used upon the tube and
more than one notch or projection may be made in or upon the catch, bolt or lever,
to engage with the said collar or collars.
Further. The tail end of the spring catch or the bolt itself may be so extended
that it shall reach to, or extend beyond the surface of the outside of the lamp, that
is, it shall pass through a hole in the side of the said lamp, such hole.being either
through the body proper of the lamp or through such part which is below the body
proper. Upon the lamp is further provided a sliding door or catch which when
open would permit of the interior catch or bolt fastening moving sufficiently to
allow of its passing over and under the collars or rings aforesaid, but when the
Baid door is closed over the end of the fastening, the latter cannot move and is
therefore locked under one of the collars or rings aforesaid. This door may be
made to slide or to rotate, or hinged as may be most convenient.
If desired the fastening may be used without the locking door or catch, and the
extension part of the fastening may be turned down so as to pass through the
bottom of that part of the lamp, and be there manipulated or withdrawn direct by
hand or be controlled by locking device as before stated.
Instead of using the door or catch device as before stated, I may employ a part
rotating keylike device, which would be operated from the exterior of the lamp,
but having an arm which may be turned down into a horizontal position behind the
fastening, either upon the interior or exterior of the lamp bottom, to suit the
construction of the said fastening.

page_text: Improvements in Mechanism for the Seouring of the Candle Tubes:
to Carriage or other similar Lamps.
I, WILLIAM TUCKER WEBBER, of City Lamp Works, Bishop 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 relates to improvements in mechanism for securing the candle
tubes of carriage or other similar lamps to the bodies of such lamps.
In order to more clearly explain this my invention I have appended hereunto
illustrative sheets of drawings upon which are figures and numbers of reference
similar numbers referring throughout the several views to the same thing or part..
Fig. 1 shows this my invention in sectional elevation showing the candle tube in
its secured position.
Fig. 2 shows a side view in plain elevation of the fastening.
Fig. 3. is a view in sido section, of the invention showing the candle tube in its.
unfastened position.
Fig. 4 shows a side view in plain elevation of the unfastened position of the
parts.
Figs. 5 to 14 inclusive illustrate modified forms of this my invention in which
Fig. 5 shows the candle tube fastened, Fig. 6 being a plan view of Fig. 5, while
Fig. 7 shows it unfastened; Fig. 8 being a plan view of Fig. 7; Fig. 9 again shows
it fastened, Fig. 10 is a plan view of Fig. 9, while Fig. 11 shows this arrangement
again unfastened; Fig. 12 again shows it fastened and Fig. 13 unfastened, Fig. 14
being a plan view of Fig. 13.
Referring to Figs. 1 & 3, upon the exterior of the upper end of the candle
tube 16 are made one, two, three, or more all round collars, rings or beads 17, at
any desirable distance from each other along the said tube, as may be required or
desired according to fastenings hereinafter stated. The particular sectional shape
of these rings &c. may be varied to suit the requirements of those fastenings, or
similar to, those hereinafter mentioned.
Within the bottom part of the lamp body or upper part of the socket, a spring
catch, lever or holt, 18 or similar device is so arranged so that when the candle
tube is pushed up, even but a small distance the first or more of the rings or
beads. 17 shall have passed or pushed its way by the catch or bolt so that the latter
may pass back underneath the ring, collar or bead, as shown under the second ring
in Fig. 1, so that the tube cannot fall therefrom. When properly pushed home
the said catch or bolt would pass underneath the lowest of such collars &c.
If desired one or more of such rings or collars may be used upon the tube and
more than one notch or projection 19 may be made in or upon the catch, bolt or
lever 18, to engage with the said collar or collars.
Further. The tail end 20 of the spring catch or the bolt may be so extended
that it shall reach to, or extend beyond the surface of the outside of the lamp, that
is, it may pass through a hole 21 in the side of the said lamp, such hole being
either through the body proper of the lamp or through such part which is below
the body proper as shown. Upon, the lamp is further provided a sliding door or
catch 22 which when open would permit of the interior tail end. 20 moving.
Bufficiently to allow of the projection 19 passing over and under the collars or rings
.aforesaid but when the said, door 22 is closed over the end 20 the latter cannot
move and the fasteuing is therefore locked under one of the collars or rings 17
aforesaid. This door may be made to slide or to rotate, or hinged as may be most.
convenient.

page_text: Instead of using the door or catch device as shown in Figs. 1 to 4 I may employ
a part rotating key like device as shown Figs. 5 to 14 which would be operated
from the exterior of the lamp.
Referring to Figs. 5, 6, 7 & 8 it will be seen that the spring catch 18 is locked
in position by means of the part rotating koy or lump 22 carried on the spindle 23,
which latter is pivotted in bearings 24, 24, and operated by the external thumb
and finger piece 25. In Figs. 5 & 6 the lump 22" is shown turned down into the
horizontal position by which the catch 18 is blocked up to the collar 17 and.
thereby looked while in Figs. 7 & 8 the lump 22" is turned up, thereby permitting.
motion to the spring catch 18" by which the candle tube can readily be withdrawn..
In Figs. 9, 10 & 11, I have shown a further modification of the fastening device
in which the spring catch instead of being in one solid piece, it may be of a doubled
shape as seon at 18. In this case also instead of carrying the part rotating spindle
through the side of the lamp (as in Figs. 5, 6, 7, & 8, the manipulating piece 25ª
is passed through direct from the plate 22. In Figs. 9 & 10 the plate 22° is
turned down behind the collar 17 which as before locks the tube in place, but in
Fig. 11 the plate 22 is raised sufficiently to permit of the yielding of the spring
catch 18 so as to allow the withdrawal of the candle tube. A spring 26 may be
used if desired to keep the plate 22b down or in its locked position, but usually
this is not necessary. In Figs. 12, 13, & 14, instead of arranging the door as.
shown in Figs. 1 to 4 to slide behind the tail end of the spring catch, I have
arranged the door or plate 22° to move vertically, which said plate is carried upon.
the arm 27, which latter may be hinged at 28, or consist of a spring arm
shown.
as.
It will be readily seen that by depressing the piece 25" the plate 22° is drawn
below the tail end 20 of the catch 18, which permits free motion to the said catch,.
but when the candle tube is in position as seen in Figs. 12 & 14, the plato 22° is
raised behind the tail end 20 and thereby locks it.
Having now particularly described and ascertained the nature of this my said
invention, and in what manner the same is to be performed, I declare that what.
I claim is:-
1. In improvements in mechanism for the securing of the candle tubes to.
carriage or other similar lamps, the making of two or more collars or rings 17,.
upon the candle tube in combination with a fastening such as 18, substantially as
set forth and shown.
2. In mechanism such as is berein described, the combination with the lamp, and
the candle tube 16, having rings or collars (or their equivalent recesses) 17, and
catch 18, with extended end 20, of the plate or door 22, operating substantially as.
shown and set forth in Figs. 1 to 4 inclusive.
3. In mechanism such as is herein described the modified combination of the
part rotating plate 22", with the spring catch 18" or 18, and ring or collar &c. 17,.
and tube 16, all substantially operating and as shown and described.
4. In mechanism such as is herein described, the modified combination of parts.
as shown and described in Figs. 9, 10 & 11, substantially as set forth.
5. In mechanism such as is herein described, the modified combination of parts.
as shown and described in Figs. 12, 13 & 14 substantially as set forth.
6. The general combination and arrangement of parts constituting these my
improvements in mechanism for the securing of the candle tubes to carriage or
other similar lamps, substantially as herein set forth and illustrated upon the:
drawings.
