in Lamps or Burners for Painters', 'Plumbers',
and Gas Fitters' Use, and Apparatus to be Employed there-
with for Producing a Blast of Air.
I, WALTER HENRY BURDOCK, of New Street, Painswick, in the County of
Gloucester, Builder, Plumber, Glazier, &c. do hereby declare the nature of this
invention to be as follows:-.
Heretofore in painters', plumbers', and gas fitters' lamps or burners, the air
necessary to sustain the flame has been produced through the mouth of the
workman, which method of proceeding, besides having the disadvantage of being
slow, very prejudicial to health.
Now my Invention has for its object to remedy these disadvantages, and it
relates to an improved construction of lamp or burner intended for the use of
painters, plumbers, gas fitters and others, in the removal of old paint, and for
making plumbers' and gas fitters' joints generally. My invention further relates
to apparatus for creating or producing the blast of air necessary to sustain the
flame in such lamp or burner.
My apparatus for producing the blast consists of an air pump worked by hand,
or otherwise, which is in communication, by means of a tube and valve, or valves,
with an air chamber or reservoir. The upper part or cover of this air chamber is
furnished with an outlet cock to which is fitted a flexible tube for the purpose of
conveying the air, produced by the pump, and filling the reservoir, to the lamp
or burner.
This lamp or burner consists of a metal chamber of a somewhat elongated
globular shape, provided at or about its centre line with an opening in the front
thereof. In this chamber is placed cotton waste saturated with spirit. At back
this globular chamber is screwed to one end of a metal tube, the other end of
which is connected, by means of a flexible tube, to the outlet cock of the air
chamber or reservoir, above mentioned. At a convenient part in the length of this
netal tube a handle is fitted for convenience of manipulation.
The object in forming the outlet for the flame about the centre line of the
chamber, is to prevent the too rapid evaporation of the spirit supplied to the lamp
or burner, and this I regard as a special feature of my Invention.

page_text: Instead of the air pump arrangement above described, I may use a bellows
whose action is sustained by means of a spring acting upwards against the down-
ward thrust of the foot. This bellows is likewise in communication by a tube and
valve with an air chamber or reservoir, which reservoir, in this arrangement, may
be a flexible one, and to the upper part of which is fitted an outlet cock and
flexible tube for conveying the blast of air from the said reservoir to the lamp
or burner.
Improvements in Lamps or Burners for Painters', Plumbers',
and Gas Fitters' Use, and Apparatus to be Employed there-
with for Producing a Blast of Air..
I, WALTER HENRY BURDOCK, of New Street, Painswick, in the County of
Gloucester, Builder, Plumber, Glazier, &c. 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, reference being had
to the accompanying drawings, and to the letters and figures marked thereon, that
is to say.
Heretofore in painters', plumbers', and gas fitters' lamps or burners, the air
necessary to sustain the flame has either been produced through the mouth of the
workman, which method of proceeding, besides having the disadvantage of being
slow, is very prejudicial to health, or else, complicated apparatus has been employed
to produce and sustain the blast.
Now, my invention has for its object to remedy these disadvantages, and it
relates to an improved construction of lamp or burner intended for the use of
painters, plumbers, gasfitters and others, in the removal of old paint, and for
inaking plumbers' and gas fitters' joints, generally. My Invention further relates
to simple but efficient apparatus for creating or producing a continuous blast of
air necessary to sustain the flame, in such lamp or burner.
My apparatus for producing and sustaining the blast of air, consists of an air
pump, worked by hand, or otherwise, which is in communication, by means of a tube.
and valve, or valves, with an air chamber or reservoir. The upper part or cover.

page_text: of this air chamber is furnished with an outlet tap, to which is fitted a flexible
tube, for the purpose of conveying to the lamp or burner, the air produced by
the pump, and filling the reservoir.
My improved lamp or burner consists of a metal chainber of a somewhat globular
or bulbous shape, provided, at or about its centre, and at the front thereof, with an
opening or mouth for the outlet of the flame. Into this chamber is placed cotton
waste, saturated with spirit. At back, this globular chamber is screwed to one end
of a metal tube, the other end of which is connected; by means of a flexible tubing,
to the outlet tap of the air chainber or reservoir, before mentioned. At a convenient
part in the length of this metal tube, a handle is fitted for convenience of
manipulation.
The object in forming the outlet for the flame about the centre line of the
chamber, is to prevent the too rapid evaporation of the spirit supplied to the lamp.
or burner, and this I regard as a special feature of my Invention.
Instead of the air pump arrangement above described, I may use a bellows
whose action is sustained by means of a spring acting upwards, against the down-
ward thrust of the foot. This bellows may likewise be in communication, by a
tube, or by a valve, with an air chamber, or reservoir, which reservoir, in this
arrangement, may be a flexible one, and to the upper part of which is fitted an
outlet cock and flexible tubing for conveying the blast of air from the said
reservoir to the lamp or burner.
And in order that my Invention may be readily understood, I proceed to describe
the same with reference to the accompanying drawings, in which:
Fig. 1, is a front elevation of the blast producing and sustaining apparatus.
Fig. 2 a vertical section of same, and Fig. 3 a plan.
Fig. 4, is an elevation of my improved lamp or burner, shewn connected to the
blast producing and sustaining apparatus, by means of a flexible rubber tubing,
Fig. 5, a longitudinal section of the same (the tubing being removed) and fig. 6 a
front elevation.
A, is the air pump fitted with a cup leather piston B, and C is the piston rod.
D, is the air chamber or reservoir, which receives the air produced by the pump.
This air is conveyed from the air pump A, to the said chamber or reservoir D,
through the pipe or passage E, opening upwardly in the chamber D, and provided
with a stem valve d, furnished at bottom with a weight to close it on its seating,
at each upward stroke of the piston. This air pump is worked by hand, by means
of the lever G, which is jointed to the piston rod at g, and has its fulcrum in the
bearing h, secured to the top of the air chamber.
H, is a tap or cock, to which is fitted a suitable length of india rubber tubing i,
for conveying the air to the lamp or burner. Both the pump and the air chamber,
or reservoir, are firmly secured to a foot board, or base Z, by lugs y, and the air
chamber is further secured thereto by the metal strap x.
Any desired number of taps may be fitted to the air chamber, so that more than
one workman may make use of the same blast producing apparatus at the same
time, to work any requisite number of lamps or burners.
My improved lamp or burner consists of a bulbous or globular chamber S, the
front part of which is cut away at 8, in order to provide a mouth or opening for
the insertion and ignition of the cotton waste, and to serve as a exit for the flame.
The portion thus cut way leaves, as it were, a dome or hood which acts to prevent
the too rapid evaporation of the spirit used for igniting the cotton waste. T, is a
tube secured to the back of the chamber, it is furnished with a handle t, for the
purpose of manipulating the lamp or burner. At its outer extremity this tube is
provided with a nozzle t*, on which is fitted the other end of the rubber tubing i,
leading from the reservoir or chamber D. This tube T communicates with an
orifice u, in the chamber S, through which a continuous blast of air is caused to
impinge on the flame.
Fig. 7 shews a modification of the blast producing and sustaining apparatus
which, in this arrangement, is adapted to be worked by the foot. The same letters

page_text: and 3. In this modi-
of reference indicate like parts to those shewn in figs. 1,
fication, the air is produced and sustained by the foot acting on the bellows A, and
is conveyed into the air chamber D (which is a flexible one) through the valve d,
whence it escapes by the tap H, into the rubber tubing. i, to the lamp or burner.
P, is a spring for sustaining the action of the bellows.
Having now described the nature of the said Invention, and in what manner
the same is to be performed, I declare that I claim :-
