PROVISIONAL SPECIFICATION.
Improvements in Means for Selectively Using Acetylene or the like
Gas with Ordinary Lamp Apparatus.
I, EDWARD SAMUEL BOND, of Crown Works, Booth Street, Handsworth,
Staffordshire, Mechanical Engineer, do hereby declare the nature of this invention
to be as follows: -
This invention relates to improvements in or connected with acetylene or the
like gas lamp apparatus and refers more particularly to the means of adapting the
ordinary oil or candle lamps used for cycle or other purposes to the use of acetylene
or the like gas as a luminant.
In such lamps now in use the oil containers in some cases are removably attached
to the lower part by being made to slide into position, being there suitably held
by catches or the like, which in other cases, such containers are fixedly attached
to the lamps.
In dealing with the former cases I provide a plate or the like, which is suitably
perforated with air holes (if required) which said plate is made to take the place
of the container, and slide into the same position." In the centre of this plate
now attach the gas burner which is adjustably connected so that its height into
the body of the lamp may be regulated. At the underside of the lamp the burner
fitting is provided with a bulb nozzle bib or the like terminal to which a flexible
tube may be readily connected or disconnected, which conveys the gas from the
generator.
When fixed containers are used in the lamps, I provide that the said burner
fitting shall take the place of the usual removable burner, and in such cases I pass
the aforesaid flexible gas tube into the container through any suitable hole made
therein. In most cases such a hole is provided by the supply inlet which is usually
situated at one of the upper corners. In other cases where convenient, the burner
fitting may pass through and be attached to the back or the side of the lamp body
so as not to interfere with the container. In some cases it may be preferable to
make the flexible tube short in length with a union or other connection for attach-
ment to the pipe from the generator. In most of these cases I find it necessary
to provide an opening or openings in the roof of the lamp, (with outer louvre or
the like covers) for ventilation &c. to the flame from the burner.
In the case of carriage lamps where a socket tube is used for candle or otherwise,
I adapt the gas burner to take the place of, or to fit into the lamp nozzle, and carry
the flexible pipe into such tube through the bottom or the side.
By these means the ordinary lamps may be readily rendered convertible from
their usual illuminating substance to the use of acetylene or the like gas.

Gas with Ordinary Lamp Apparatus.
I, EDWARD SAMUEL BOND, of Crown Works, Booth Street, Handsworth,
in the County of Stafford, Mechanical Engineer, 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 or connected with acetylene or the
like gas lamp apparatus, and refers more particularly to the means of adapting the
ordinary oil or candle lamps used for cycle or other similar purposes to the use
of acetylene or the like gas as a luminant.
In order to more clearly explain this my invention, I have appended hereunto
illustrative drawings upon which are figures and numbers of reference, in
which:-
Fig. 1, shows my invention as adapted to a cycle lamp of the removable oil
container type.
Fig. 2, is a plan view of the gas burner and plate for such adaptation as shown
in Fig. 1.
Fig. 3, shows my invention as adapted to a lamp having a fixed oil container.
Fig. 4, shows a modification in the means of attaching the flexible gas supply
pipe which may be applied to types of lamp shown in Figs. 1 and 3.
Figs. 5 and 6, show this my invention as applied to carriage candle lamps.
Referring to lamps used for cycling and the like, in such lamps 8, now in use,
the oil containers in some cases are removably attached to the lower part by being
made to slide into position, being there suitably held by catches or the like, while
in other cases, such containers 8" are fixedly attached to the lamps.
In dealing with the former cases as shown in Figs. 1 and 2, I provide a plate 9,
which is suitably perforated with air holes 10, (if required) which said plate is made
to take the place of the container, and slide upon the slideways 11, 11, into the
same position. In the centre of this plate I now attach the gas burner 12, which
is carried upon the screw-threaded pipe 13, having lock nuts 14, 14", by which
it is adjustably connected so that its height into the body of the lamp may be
regulated. At the underside of the lamp the pipe 13, is provided with a bulb
nozzle bib 15, to which a flexible tube 16, may be readily connected or disconnected,
which conveys the gas from the generator.
When fixed containers are used in the lamps as seen in Figs. 3 and 4, I provide
that the plate 9ª, shall be made with depending flange 17, upon which is formed
the usual bayonet joint or other fastening, so as to take the place of the usual oil
burner body, and in such cases I pass the aforesaid flexible gas tube 16, into the
container through any suitable hole made therein. In most cases such a hole is
provided by the ordinary supply inlet 18, which is usually situated at one of the
upper corners. In other cases where convenient, as seen in Fig. 4, the burner
fitting 13, may pass through the side or the back of the lamp body so as not to
interfere with the container, and the flexible pipe 16, there attached as before.
In carrying out my invention of adapting the gas apparatus to carriage candle
lamps, it will be seen upon reference to Figs. 5 and 6, that I adapt the gas
apparatus to accommodate and fit in the usual candle tube of the lamp, or to take
its place.
19, is the body of the lamp proper, 20, is the nozzle, 21, is the lamp socket which
fits into the usual lamp iron (not shown), 22, is the removable candle tube. Such

page_text: tubes are secured in position by various devices, but as these do not interfere with
this my invention, I have not shown any.
Referring now to Fig. 5, it will be seen that the burner pipe 13, has the extended
pipe 13b, whose lower end protrudes through the bottom of the tube 22, and is there
connected to the pipe 16. Upon the pipe 13, is carried the adjustable nozzle stop 23,
which is adjustably fixed in position by lock nuts 14, 14", by which the height of
the flame above the nozzle 20, may be fixed. 24, is a spring (which may be the
same as used for the candle) by which the nozzle stop 23, is held up to its position.
Referring to Fig. 6, it will be seen that instead of the pipe 13°, continuing
downwards the whole length of the tube 22 (as in Fig. 5) I may arrange to connect
the gas pipe 16 through its side, so as to afford what may appear a neater form.
In this case I provide a slot hole 25, and a base 26, upon the pipe 13º, having a
passage communicating with the said pipe 13. The spring 24, is again used to
steadily keep the whole in position and from shaking. The fitting having been
passed down the tube 22, until the base 26, is opposite the hole 25, the screw
pipe 27, is secured into the base 26, through the hole 25, and thence the supply
pipe 16. The nozzle stop 23", in this case is screwthreaded to accommodate the
screw nozzle flange 31, so that when the device is passed upwards into the lamp,
the nozzle flange 31, firmly secures the whole.
By these means the ordinary lamps are readily rendered convertible from their
usual illuminating substance to the use of acetylene or the like gas.
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. The adaptation of and combination with lamp 8, having slideways 11, 11, of
the removable plate 9, and pipe 13, carrying burner 12, all substantially as set
forth and shown in Figs. 1 and 2.
2. The adaptation of and combination with lamp 8, having fixed container 8",
of the removable plate 9", having flange 17, with suitable fastenings, pipe 13, and
flexible tube 16, conveyed to interior of said container, substantially as set forth
and shown in Fig. 3.
3. The combination with lamp having container 8", plate 9", burner pipe 13, of
the pipe 13, passing through side of lamp as set forth and shown in Fig. 4.
4. The combination with lamp 19, nozzle 20, and candle tube 22, of the pipe 13b,
having nozzle stop 23, adjustably carried thereon, with burner 12, spring 24, and
supply pipe 16, all substantially as set forth and shown.
5. The modified combination of nozzle stop 23, pipe 13°, with base 26, having
supply inlet through hole 25, substantially as set forth and shown in Fig. 6.
6. Adjusting the height of burner 12, upon plates 9, 9", by means of screw
pipe 13, with lock nuts, substantially as set forth and shown in Figs. 1, 2, 3 & 4.
7. Adjusting the height of burner 12, with nozzle 20, by means of screw pipe 13,
nozzle stops 23, 23, and lock nuts, substantially as set forth and shown in Figs. 5,
& 6.
