AN IMPROVED INSTANTANEOUS CAPILLARY GENERATOR
Year: 1880

page_text: LETTERS PATENT to Arthur Charles Henderson, of 6, Southampton Buildings,
Holborn, in the County of Middlesex, for an Invention of "AN IMPROVED
INSTANTANEOUS CAPILLARY GENERATOR." A communication from abroad by
Jean Joseph Guignet, Mechanician, of Lyon, in the Department of Rhone and
Loire, in the Republic of France.
PROVISIONAL SPECIFICATION left by the said Arthur Charles Henderson
at the Office of the Commissioners of Patents on the 22nd November 1880.
ARTHUR CHARLES HENDERSON, of 6, Southampton Buildings, Holborn, in the
County of Middlesex, "AN IMPROVED INSTANTANEOUS CAPILLARY GENERATOR."
A communication from abroad by Jean Joseph Guignet, Mechanician, of Lyon, in
the Department of Rhone and Loire, in the Republic of France.
This generator consists,-
1st. Of a single tube of very small diameter and of a length in proportion to the
power of the machine; this tube is arranged in a furnace either in concentric
screws with closed spirals or with open ones, one above the other, the flame of the
furnace passing between each spiral, the said spirals being maintained at each
interval by uprights.
The small volume of water contained in the generator is heated and is rapidly
transformed into steam. Valves conveniently placed prevent accidents, and the
small diameter of the tubes dispels any fear of explosion.
Thus for a steam generator of 20 horse power, for example, 8 to 10 millimetres in
diameter suffices for the tubes.
2nd. A steam recipient at the upper part where the steam distributer is placed.
3rd. Of two suction and force pumps for feeding. The accompanying Drawings
represent by,-
Fig. 1, a front elevation of the generator, a part being in transverse section.
Fig. 2, a plan and horizontal section following X, Y; Fig. 3, a vertical
elevation seen from the side of the generator.
The same letters of reference indicate like parts seen in the different Figures.

page_text: A is the body of the generator; B, the side in refractory earth against the side
of the generator; C, spiral screws; D, recipient of hot water and steam; E, extremity
of the tube at the large part of the screw, admitting the steam into the recipient;
F, float placed in the recipient and automatically regulating the feed by aid of a
valve; G, pipe receiving the hot water from the recipient, and at once circulating
it by the sucking and forcing pump into the generator by aid of the tube H, com-
municating with the screw; I, suction pipe of cold water forced into the recipient
by the tube J; K, tube leading the steam to the cylinder L of the machine. This
tube may pass into a reheater so as to have the steam dryer, and be thence led to
cylinder; M, escape pipe of steam from the cylinder; N, valve below for the water;
O, valve above for the steam.
The above described generator can be applied to any kind of motor, especially
those requiring a limited space and lightness of generator, for navigation, traction
on road or rail, and so forth.
Finally, what is claimed by the inventor is the improved generator as herein
described and as illustrated, consisting of a generator which he terms instantaneous
and capillary, composed of a tube of very small diameter arranged in open or closed
spirals, reservation being made to any modifications of form or detail that may be
deemed advisable or convenient.

the said Arthur Charles Henderson in the Great Seal Patent Office on the
19th May 1881.
ARTHUR CHARLES HENDERSON, of 6, Southampton Buildings, Holborn, in the
County of Middlesex. "AN IMPROVED INSTANTANEOUS CAPILLARY GENERATOR."
A communication from abroad by Jean Joseph Guignet, Mechanician, of Lyon, in
the Department of Rhone and Loire, in the Republic of France.
This generator consists,-
1st. Of a single tube of very small diameter, and of a length in proportion to the
power of the machine; this tube is arranged in a furnace, either in concentric
screws with closed spirals or with spirals open one above the other, the flame of the
furnace passing between each spiral, the said spirals being maintained at each
interval by uprights. The small volume of water contained in the generator is
heated and is rapidly transformed into stean.
Valves conveniently placed prevent accidents, and the small diameter of the
tubes dispels any fear of explosion. Thus for a steam generator of 20 horse power,
for example, 8 to 10 millimetres in diameter suffices for the tubes.
2nd. Of a steam recipient at the upper part where the steam distributer is
placed.
3rd. Of two suction and force pumps for feeding, which are directly actuated by
a small piston worked by the generator itself.
The accompanying Drawings represent by,-
Fig. 1, a front vertical projection of the generator, a part being in transverse
section.
Fig. 2, a plan and horizontal section following X, Y.
Fig. 3, a vertical projection seen from the side of the generator. The same
letters of reference indicate like parts seen in the different Figures.
A, body of the generator; B, side in refractory earth against the case of the
generator; C, spiral screws; D, recipient of hot water and steam; E, extremity of
the tube from the large part of the screw, admitting the steam into the recipient;
F, float placed in the recipient and automatically regulating the feed by aid of a
valve; Ġ, pipe receiving the hot water from the recipient, and at once circulating it
by the sucking and forcing pump into the generator by aid of the tube H, com-
municating with the screw; I, suction pipe of cold water forced into the recipient
by the tube J; K, tube leading the steam to the cylinder L of the machine. This
tube may pass into a reheater, so as to have the steam dryer, and be thence led to
the cylinder; M, escape pipe of steam from the cylinder; N, valve below for the
water; 0, valve above for the steam.
The above described generator can be applied to any kind of motor, especially
those requiring a limited space and lightness of generator for navigation, traction
on road or rail, and so forth.
Finally, what is claimed by the inventor is the improved generator as herein
described and as illustrated, consisting of a generator which is termed instantaneous
and capillary, composed of a tube of very small diameter, arranged in open or closed
spirals, reservation being made to any modifications of form or detail that may be
deemed advisable or convenient.
In witness whereof, I, the said Arthur Charles Henderson,have hereunto set
my hand and seal, this Seventeenth day of May, in the year of our Lord
One thousand eight hundred and eighty-one.
