PROVIDIONAL DI MOTIVATIO
An Acetylene Gas Generator and Adjustable Burner for Cycle,
Carriage, and other Lamps.
CHARLES RICHARD BEAUMONT, Tomes House, Whitehall Street, Rochdale,
Lancashire, do hereby declare the nature of this invention to be as follows:-
Acetylene gas generator suitable for cycle, carriage, & other portable lamps.
The generator A, Fig. I, is attached to the underneath part of lamp, by means
of a screw thread. a 1.
A water vessel B, is fixed in any convenient position above the generating
chamber, and is filled through a cap closed aperture at the top 61.
Leading from the water vessel to generator is a tube C, having a valve or tap c 1.
The water tube C is carried downwards through a casing or sleeve, in the
generator, to within half an inch of bottom, and terminates in a nozzle, to which
is attached a back pressure valve D, for controlling water supply automatically;
by means of the gas generated, and thereby regulating pressure within the
generator.
Within the generator is a loose casing or sleeve E, closed at the lower end by
a disc e 1, the said sleeve or casing is perforated at the sides, for about two thirds
of its length, to aid the distribution of water evenly through the calcium carbide,
contained in the generator.
The loose sleeve E, with disc attachment serves as a discharger, for cleaning out
the residue left when the carbide is exhausted.
Attached to the generator is a chamber F, for purifying the gas.
A portion of this chamber is charged with anhydrous copper sulphate, mixed
with sufficient calcium chloride, to form a stiff mass. In the neck of generating
chamber is a perforated disc, f 1, which covers the carbide, & prevents any stray
particles from choking up the gas passages, when travelling over rough roads.
The gas after passing through the purifier, enters a drying, & filtering chamber, G,
which is filled loosely with absorbent cotton, or other suitable material.
The drying chamber G, is fitted with a screw cap, for convenience of refilling
with the drying & filtering medium, when required.
From drying chamber the gas passes direct to burner H, which is made in two
parts, the lower portion h1, has a perforation or gas passage of suitable size,
through bottom. The upper portion H, has a central adjustable pin I, having a
slightly taper, or conical end i 1, which projects into the aperture in the nozzle of
burner & is actuated by a screw adjuster for the purpose of regulating size of
flame,
The screw adjuster is also used for cleaning out nozzle of burner, when required,
The upper portion H, of burner, fits into a coned socket, in lower portion, & is
ground to an accurate fit, so that it may be easily detached, when required to
clean out burner, or adjust the flame.
Fig. II. represents the form of apparatus preferred for carriage, & other lamps,

page_text: where it may be desirable to have the generator &c. separate, & connected to the
burner or burners by a flexible or other tubing.

An Acetylene Gas Generator and Adjustable Burner for Cycle,
Carriage, and other Lamps.
CHARLES RICHARD BEAUMONT, Dental Surgeon, Tomes House, Whitehall Street,
Rochdale, Lanc., do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement:-
This invention relates to a portable acetylene gas generator lamp, and burner,
of that class in which the gas is generated by a drip of water through a capillary
tube from a water vessel placed above the carbide chamber or generating vessel.
My invention relates particularly to the means whereby the flow of water is con-
trolled to the generator; to the mode of purifying the gas; to the method of
adjusting burner so as to regulate quantity of gas produced, and consumed, and to
sundry other details as hereinafter described with reference to the accompanying
drawings forming part of this specification wherein Fig. I is a longitudinal section
of the generator with superimposed water vessel, lamp and burner complete show-
ing the improvements.
Fig. II. represents the form of apparatus preferred where the lamp, or burner
and generator are separated
Fig. III. is a longitudinal section of burner showing the improved method of
regulating quantity of gas consumed and of increasing or decreasing the illumin-
ating power of flame.
The same letters of reference indicate the same parts in all the figures.
A Fig. I. is the gas generating chamber attached to the lower part of lamp by
means of a screw thread, or the like device for making a gas tight joint.
B is a water vessel fitted with a cap closed aperture at the top b 1.
C is a tube leading from the water vessel to within half an inch of bottom of
generator. The said tube is fitted on the upper part with a valve or tap e I, and on
the terminal end is attached a short length of indiarubber tube having a transverse
slit and closed at the end by an elastic cap forming a very sensitive hinged clack
or valve D. This valve acts automatically, by means of the water pressure on the
one hand, and gas pressure on the other, and is for the purpose of automatically
regulating the supply of water admitted into the generator, and thus controlling
the generation of gas within the chamber, to the requirements of the burner.
To prevent injury to the valve it is covered by means of a small ferrule, not
shown in the diagram.
Within the generator is a loose sleeve E, having a circular disc or foot.
The said sleeve is made so as to slide easily on water tube, and is perforated
around its sides so as to aid the distribution of water evenly through the calcium
carbide contained in the generator.
The disc foot attachment serves as a discharger for cleaning out the calcium
residue left when the carbide is exhausted.
F is a chamber for purifying the gas, a portion of this chamber is charged with

page_text: anhydrous copper sulphate mixed with sufficient calcium chloride to form a stiff
mass.
A
In the neck of generating chamber is a perforated disc or cover f 1, for the
purpose of preventing any stray particles of carbide from choking up the gas
passages when travelling.
G is a drying and filtering chamber and is filled loosely with absorbent cotton
or other suitable filtering medium. The burner H, Fig. III, is fitted with an
adjustable pin I, having a slightly tapered end i 1, which projects into the aperture
in the nozzle, and is actuated by a screw, for the purpose of regulating the quantity
of gas consumed.
The upper part of burner h1, is perforated at the sides, for the purpose of
admitting air, and thereby providing a mixture of gas and air within the burner
chamber.
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. A portable acetylene gas generator, having an automatic water and gas
regulator, as described.
2. An improved means of purifying and drying the gas as hereinbefore stated.
3. An acetylene gas burner capable of being adjusted so as to pass a larger or
smaller quantity of gas, as, and for the purpose specified.
