Packed Barrel Burner for Lighting and Heating, and Prevention
of Explosions in the Use of same.
I THOMAS GOODWIN, of Campbell Road Bilston, near Rugby '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 lime-light jets or burners for magic lanterns, and has
for its object to provide a simple, cheap, readily constructed and perfectly operating
device of this character; a further object being to provide a barrel for this and
other purposes which will be flame proof.
The invention consists in the novel construction and arrangement of parts
hereinafter fully described.
Referring to the drawings;
Fig. 1 is a side elevation of a device embodying my invention.
Fig. 2 is a longitudinal section of the body portion thereof.
Fig. 3 is a section on the line y y of Fig. 2.
In the practice of my invention I construct a brass tube or barrel A packed
tightly from end to end with strips or pieces of fine copper wire a and at or near
cach end of the barrel is formed annular heads or shoulders B, outside of which, at
each end is a screw threaded extension C. To one of these screw threaded
ends C is secured a hollow conical attachment D by means of a screw thread in the
interior of its base; and to the apex or outer end thereof is similarly secured
a curved discharge or burner tube E having at its free end a discharge nipple F.
At the other or front end of the tube or barrel A is secured a head G having a
central longitudinal bore g the outer end of which is enlarged forming a conical
valve seat H at the outer end of which is formed a chamber the inner side walls
of which are screw threaded to receive a screw threaded plug jon which is formed
t its inner end, a conical valve K adapted to be seated on the valverseat H.
Mounted upon the plug j is a set nut k and the outer end thereof is provided with
milled head or plate. L by which the plug and valve are operated.
Communicating with the central bore g in the head G is a diagonally arranged

page_text: bore M with which is connected an oxygen tube m and diagonally opposite is a
similar bore N with which communicates a hydrogen tube n.
As thus constructed, the valve K, when closed, completely cuts off the supply of
oxygen but a small groove k¹ formed in the end of the valve or in the head G will
permit the passage of sufficient hydrogen to maintain the light and the thread on
the plug is of such pitch as to open the valve with half a turn or less.
In front of the head G on the barrel A is mounted a plate or arm O secured to
a standard O' by a screw o, having a milled head o', and upon the central piston
of the barrel A, is a bracket P, secured thereto or formed thereon, having two
side plates R, but one of which is shown and between which is the adjustable slide
or base r, of the frame or bracket S, which is held in place by a set screw r³.
The frame S, is provided with forwardly directed arms s, through which passes
a screw threaded rod U, on which is mounted a beveled gear wheel W, which gears
with a corresponding beveled gear wheel W', mounted on the end of a rod w, which
passes through the back of the frame S, and also through the armn O, and is
provided at its outer end with a milled head w¹, by which the rod and beveled gear
wheels are operated.
The screw threaded rod U, carries at its upper end the lime-stick or pencil V,
and independent means may be provided if desired, to vertical adjust said pencil
in the rod U, said rod being hollow or provided with a cavity at its upper end.
These elements of construction however, form no part of this invention and are not
shown.
The operation will be readily understood in view of the foregoing description
taken in connection with the accompanying drawing. The frame or bracket S, is
adjustable upon its support P, and may be held in any desired position, by the set
screw, the rod w, sliding freely in arm O, to admit of this action. The rod V,
carrying the lime-stick or pencil can be turned and vertically adjusted by operating
the rod w, as will be readily understood, and it will also be understood that by
operating the valve K, by means of the milled head L, the supply of oxygen can
be cut off at any time or regulated to any desired extent, as may also the hydrogen
supply, it being understood, of course, that both the oxygen and hydrogen supply
pipes m and n, are provided with independent valves not shown.
As thus constructed, however dangerous the gases employed may be, there is no
danger of explosion, for the reason that no flame or flame jet can pass through the
barrel A, packed longitudinally with fine copper wire, as described. The supply
of gas may be evenly regulated, and if the hydrogen supply is too great by simply
moving the cut off valve, the supply thereof, may be readily adjusted to the desired
extent.
My improved burner gives a steady and a brilliant light, the packing in the
barrel A, being in itself a perfect 'regulator, and it forms a perfect dissolving
apparatus for lantern or similar devices as the oxygen supply can be cut off instantly
if desired, and immediately turned on again, by simply moving the milled head L,
which operates the valve K. It is evident that any kind of gas may be employed
in this burner, and it is not limited to the use of hydrogen and oxygen as herein
described.
'Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I describe that what
I claim is :-
1. In a gas burner herein described, a regulator composed of a barrel or tube,
packed with fine wire, substantially as shown and described.
2. In a magic lantern or other burner, the combination with a tube or barrel, of
a curved burner tube connected with one end thereof, and provided with a discharge
nipple, gas supply pipes communicating with the opposite end of said tube, and
controlled by a single regulating valve, and means connected with the barrel for
supporting the lime-stick or pencil, which is adjustable with reference to said
discharge nipple, substantially as shown and described.
