Improvements in or relating to Torches.
I, HERBERT JOHN HADDAN, of the Firm of Herbert Haddan & Co., of
18, Buckingham Street, Strand, W.C.,.London, Civil Engineer, do hereby declare
the nature of this invention a communication to me from abroad by Henry
Wellington, of 449 Putnam Avenue, Brooklyn, N.Y., United States of America,
Manufacturer, to be as follows:-
This invention relates to torches such as are employed by plumbers, painters and
others, and especially to torches burning liquid fuel under air pressure.
I apply upon the top of the reservoir, a fitting which is perforated and serves as
the filling orifice through which is charged, and this is arranged to receive and
hold the pump.
In one form the fitting has a branch which receives the upper end
of the handle. The pump piston is mounted upon a section of a holder of which

perforated, and one section sustains the check valve in the form of a narrow strip
of oiled silk or like substance.
The barrel of the pump is made movable while the piston remains stationary.
The exterior of the piston holder is grooved on opposite sides and the barrel

supplied with screws or pins movable in the grooves.
grooves are branches which receive the screws or pins when the barrel is properly
turned and thus the pump is locked.
The supply pipe passes through the reservoir at bottom, has a small perfora-
tion in it and is bent and extended up to the burner. The joints are secured
by soldering. In the lower end of the tube is a fitting which receives the lower
end of the handle and this fitting is connected with the branch above by a bolt
passing through the handle.
To clear the supply pipe I employ a packing made of wire cable which may be
drawn back and forth in the tube on removing the burner.
The reservoir, including the base rim and top is formed in a single piece-the bottom
plate is located in a recess provided for its reception-and the margin of the recess
is then turned down to place and the bottom afterwards made secure against
leakage by soldering.
Deted this 31st dow of May 1894.

I HERBERT JOHN HADDAN of the Firm of Herbert Haddan and Co. of
18 Buckingham Street Strand W.C. London Civil Engineer, do hereby declare
the nature of this invention a communication to me from abroad by Henry.

Manufacturer and in what manner the same is to be performed to be particularly
described and ascertained in and by the following statement :-
My invention has relation to torches such as are employed by plumbers, painters

page_text: material is used for fuel the same being burned under pressure produced by air
compressed in the reservoir and it (the invention) involves certain new and useful
features as will be herein fully explained.
In the drawings
Fig. 1 is a view partly in section and partly in elevation showing a torch with
my improvements applied.
Figure 2 is a view showing the pump detached, the barrel in section and the
interior parts in elevation.
Figure 3 is a cross-section and elevation upon a plane through the holding pins
in Fig. 2.
A. is the reservoir which may be of any size, and shape. B the burner of any
suitable pattern, and C. the supply pipe for conducting fuel to the burner.
D. is a
fitting applied upon the top of the reservoir, the same being perforated and serving
as the filling orifice and being threaded or otherwise arranged to hold the pump.
This fitting D is shown as supplied with a branch D¹ which receives the top of the
handle E and serves to connect it at one part with the reservoir, but this branch is
not always essential.
F is the piston, which may be in the form of a leather cup, this is mounted, upon
a section G. of a rod or holder of which the remaining part His fitted to enter the
filling orifice, and to be removably held therein.:
The two sections of the rod or holder are perforated through and through the
section G sustaining on its inner end (reduced for the purpose) the check valve a
which is in the form of a narrow strip of oiled silk or like substance tied, in place
as by a thread indicated at b. This valve covers the orifice through section G.
admitting air to be forced down through the section and out under the margins of
the strip; but automatically closing the orifice against the passage of air or gas
in the opposite direction.
I is, the barrel of the pump; in this case made movable while the piston remains
stationary. The exterior of the part H of the piston holder is grooved on opposite
sides as at cc and the barrel I supplied with screws or pins d d entering the said
grooves but permitting the barrell to be moved back and forth, upon the holder..
The barrel is slightly enlarged near its open end as at e.and when drawny back
far enough upon the holder to clear the piston Fair enters through: this: enlarge-.
ment, is trapped by reversing the motion of the barrel and then forced through the
central perforation in the section G; past valve a through the central perforation f
in the section H and thence into the reservoir..
At the inner ends of grooves or channels cc are branches cc. These, receive
the screws or pins d d when the barrel is properly turned and in this way the pump.
is-locked against accidental disarrangement: The arrangement.. is.. simple, compact:
and strong the pump is within convenient reach of the operator and it delivers the
air always above the fuel so that leakage of; fuel through. the pump; is entirely
obviated.
The pump serves to close the filling orifice and may be removed for filling
whenever required. The pipe C communicates with the interior of the reservoir
through a small orifice g passes through from one side to the other of the reservoir,
is bent and extended upwardly and receives the burner at its upper end, being
braced to the reservoir by any suitable bracket. as, K. Solder, is applied to render
the joints perfectly tight and the fitting D is similarly secured, the interior soldering
being accomplished before the bottom plate. L is fixedrin, place.

In the lower end of tube C is a fitting M. calculated to receive the lower end of
the handle E and the fitting M is connected with branch D! by a screw bolt h passing
through the handle.
The pipe C being devoid of elbows and joints such, as heretofore employed, is
not only cheaper and easier to construct and apply but affords a more satisfactory
conductor for the fuel and enables me to supply and operate means for clearing out
the tube when it becomes clogged. For this I employ a packing O made of small

page_text: wire cable of sufficient rigidity for the purpose. By removing the burner the
packing may be drawn back and forth in the tube thus clearing the latter, and the
packing itself may be cleaned by fire or otherwise.
The reservoir shell including the base rim and top is formed in a single piece-
the bottom plate L is located in a recess provided for it as shown. The margin
of the recess is then spun down to place, and the bottom afterwards made tight by
soldering.
Having now particularly described and ascertained the nature of this inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
1. In combination with a reservoir top a fitting D containing the filling orifice,
and a removable air pump applied in said orifice and arranged to close the same
substantially as set forth.
2. In combination with a reservoir for containing liquid fuel an air pump com-
prising a stationary piston mounted on the reservoir and a movable barrel operating
in conjunction with said piston substantially as set forth.
3. In combination with a reservoir for containing liquid fuel the herein described
pump composed of a perforated piston holder, a valve located therein a piston, and
a pump barrel the exterior of the piston holder being grooved and the barrel being
provided with pins or screws substantially as shown and described.
4. In combination with a reservoir for containing liquid fuel the supply pipe
leading to the burner, the fitting for receiving the lower end of the handle and the
rod joining said fitting, with a branch of the fitting containing the filling orifice
substantially as shown and described.
5. In combination with a reservoir for containing liquid fuel, the supply pipe
passing through the reservoir at two points, the same being secured to the reservoir
and being bent and extended up to receive the burner substantially as set forth.
6. In combination with the bent supply pipe leading from the reservoir to the
burner, the packing of wire cable the same being adapted to be moved back and
forth within the pipe to clear the same substantially as set forth.
7. The shell of the reservoir made in one piece with the top and lower rim and
the bottom plate secured in place by bending the metal of the shell upon it and
then soldering substantially as shown and described.
Dated this 26th day of March 1895.
