Improvements in Apparatus for Automatically Generating and
Burning Inflammable Vapors.
I, CLAUDE ANDRÉ PAQUELIN of 12, Place Vendôme, Paris, France, Doctor
of Medicine, do hereby declare the nature of this invention to be as follows:
My invention relates to improvements in blow-pipe apparatus for automatically
generating and burning inflammable vapors, forming the subject of previous
Letters Patent dated the 21st day of May 1886, No. 6859, and relates:-
1st. To means for regulating the action of the generator and the intensity of the
flame produced.
2nd. To an independent feed reservoir whereby to enable the apparatus to be
used for a long period without intermission.

relatively large capacity of the reservoir p the apparatus may be used continuously
for several hours and thus be rendered suitable for many uses and more particularly
for the production of light by the incandescence of magnesium, platinum, or other
refractory bodies, as well as for producing an intense and prolonged heat as is
required in many scientific and industrial operations.

Improvements in Apparatus for Automatically Generating and
Burning Inflammable Vapors.
I CLAUDE ANDRÉ PAQUELIN, of 12, Place Vendôme, Paris, France, Doctor
of Medicine, 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 :-
My invention relates to improvements in blow pipe apparatus for automatically
generating and burning inflammable vapors, forming the subject of previous Letters
Patent dated the 21st day of May 1886, No. 6859.
The principal features and advantages which distinguish the apparatus
consist :-
1st. In means for regulating the action of the generator and the intensity of the
flame produced.
2nd. In dispensing with the use of free liquid in the generator and the substitu-
tion therefor of a porous material whereby (a) the inconveniences attending the
use of liquid are avoided (b) all danger of explosion in the normal working of
the apparatus, whether due to carelessness or incompetency of the operator
(c) the clogging of the orifice of the burner is prevented (d) the apparatus will remain
in action for a longer time with a supply reservoir of the same size.
3rd. In an independent feed reservoir whereby to enable the apparatus to be
used for a long period without intermission.

page_text: Reference is to be had to the drawings left with my Provisional Specification
and also to the accompanying drawing, forming part of this Specification, wherein
Figure 1 represents a vertical section, and Figure 2 a plan on an enlarged scale,
of the jet nozzle and regulator.
Figure 3 is a vertical section of the regulator in the open position.
Figure 4 is a horizontal section of a modified arrangement of regulator.
Figure 5 is a vertical section of the apparatus, provided with a modified
arrangement of regulator.
Figure 6 is a vertical section of an apparatus provided with an independent
reservoir.
Figure 7 is a vertical section, taken on line 1-2 Figure 6.
Figure 8 shews a vertical and longitudinal section of an apparatus in which the
body of the vessel is filled with porous material.
The same letters of reference denote like parts in all the figures.
The general arrangement of the apparatus is the same as that described in the
Specification of the former Letters Patent before referred to, except that one end
of the passage a for the inflammable vapor is closed, as shewn, and the other end
forms a seat for a valve b by which the passage of the vapor to the nozzle c is
regulated, to suit the effect to be produced.
The valve may be adjusted in various ways, three arrangements being shewn.
In Figures 1, 2, and 3, the stem of the valve has an eye through. which
passes the eccentric part of a cross-spindle fitted to be turned in a socket f by
means of the ring ³, whereby the valve b can be readily adjusted to regulate the
flow of vapor, after which the screw is to be tightened up. Once this adjust-
ment made, the head of screw 2 can be cut off so as to prevent any subsequent
disarrangement of the valve b. is a thin metal diaphragm, of sufficient flexibility,
attached, by welding or otherwise, to valve and socket f for preventing the
escape of the vapors.
In Figure 4 the vaive is on the end of a wire b coiled around the apparatus and
enclosed in an air tight tube & to which it is attached at the outer closed end the
other end of the tube being soldered or otherwise fixed to the flange m of socket /,
the tube fulfilling the purpose of the diaphragm before described. n is a screw
turning in a nut fixed at the free end of the tube whereby the tube may be
adjusted, by being slightly uncoiled, so as to bring the valve as close as required
to its scat in the end of passage a, for the purpose of regulating, as in the
preceding arrangement, the action of the apparatus and the intensity of the jet
produced thereby. The screw n, instead of being placed transversely to the tube k,
may also be applied to act in a longitudinal direction by bearing, for instance,
on, the free end of the tube to force the valve towards its seat.
For this purpose
the end would have a flexible cap. Or the screw might be applied to act upon
the tube at any point of its length.
In Figure 5 the valve stem 6 passes through a thin metal diaphragm i, for
preventing the escape of the vapors as in the first described arrangement, and is
connected by a coupling d to a screw e turning in a nut g and provided with a
milled head by turning which the valve may be adjusted in its socket f to
regulate the quantity of vapor entering passage a. Any other suitable means of
regulating the valve may be adopted.

Figure 8 represents, in vertical and longitudinal section, an arrangement of
of generator containing porous material, such as carded cotton, wadding, or its
equivalent, supported upon a backing of canvas or other material. The generator
is provided with a chamber A surrounding the central wick y and enclosed by a
wire gauze partition B, between which and the outer wall D and bottom of the
apparatus is contained the porous material C by means of which a considerable
quantity of inflammable liquid, which is introduced by a screw-capped filling
orifice, may be stored in the apparatus without leaving any free liquid therein.
This, porous material may also be applied to the apparatus described in Figure 5

page_text: as well as to that provided with. an independent reservoir, as in Figures 6 and 7,
the apparatus being when thus provided capable of working for three consecutive
hours or more, which may be still further prolonged when a separate supply
reservoir is employed.
Figures 6 and 7 represent the apparatus combined with an independent reservoir
for the continuous supply of the liquid. This reservoir p may be of any suitable
form, but preferably in that of a parallelopiped. It is provided with a handle
and contains a wick which is led through a tube s projecting centrally into the
reservoir, so as to prevent the liquid escaping in any position of the reservoir and
which may be connected to the generating apparatus by a screw or bayonet
joint z.
}'
In order that the wick may be constantly immersed in the liquid in the reservoir,
in any position of the latter, a weight is attached to the end of the wick to keep
it at the lowest point of the réservoir. The reservoir is provided with a filling
orifice v closed by a screw-cap or otherwise. The projecting end of the wick
is in contact with the central wick y within the generator, which is kept constantly
supplied with inflammable liquid by the capillary action of the wick r, the
generator itself containing no free liquid. The wick y may, however, be dispensed
with, the liquid supplied by the wick being in that case immediately vaporized
by the heat of the apparatus, whose action would be that of an automatic
gazogene.
.
By means of the improvements herein described, the dimensions of the apparatus
are considerably reduced, while by reason of the relatively large capacity of the
reservoir the apparatus may be used continuously for several hours and thus be
rendered suitable for many uses. Thus the apparatus may be employed for the
production of light, by the incandescence of magnesia, platinum, or other
refractory bodies, as well as for. producing an intense and prolonged heat as is
.required in many scientific and industrial operations.
The form and dimensions! of the component parts of the apparatus may be
varied, without departing in any way from the nature of the invention.
.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is
1st. In a blow pipe apparatus for automatically generating and burning
inflammable vapors, the combination, with the passage leading to the jet nozzle, of
the regulating valve for controlling the flow of vapor and of the flexible diaphragm
attached to the valve stem and to the enclosing socket for preventing escape of
vapor,, substantially as specified.
2nd. In the herein described blow-pipe apparatus, the combination, with the
