A NEW OR IMPROVED WARM BATH
Year: 1860

page_text: LETTERS' PATENT to Joseph Wilson, of Birmingham, in the County of
Warwick, Manufacturer, for the Invention of "A NEW OR IMPROVED
WARM BATH."
PROVISIONAL SPECIFICATION left by the said Joseph Wilson at the
Office of the Commissioners of Patents, with his Petition, on the
29th August 1860.
I, JOSEPH WILSON, of Birmingham, in the County of Warwick, Manu-
facturer, do hereby declare the nature of the said Invention for "A NEW
OR IMPROVED WARM BATH," to be as follows:-
My Invention consists of a bath made, by preference, of sheet metal, and
having externally the shape of the ordinary warm bath. The bath has a false
bottom, between which and the true bottom is a flue opening into a chamber
at one end of the bath. The true bottom of the bath rises at one end to
about two-thirds of the height of the bath, the said rising setting in at about
one quarter the length of the bath. The space enclosed between the rising
false bottom and the true bottom constitutes the said chamber. A portable
grate or fire-box fits in the said chamber, and may be inserted therein and
removed at pleasure. In using the bath it is filled to the required height with
water, and the portable grate or fire-box, filled with ignited fuel, is placed in.
the chamber. The heated air and products of combustion pass along the flue
and heat the water in the bath. When the temperature of the water in the

page_text: bath has been. raised sufficiently, the portable grate or fire-box carrying the
fire is removed. A pipe fixed in the end of the flue may be introduced into
the ash-pit or under the chimney of an ordinary fire-place, or inserted in any
other flue, so as to convey away the air which has passed through the fire.
The bath may be used as an ordinary cold bath when it is not wanted as a
warm bath
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Joseph Wilson in the Great Seal Patent Office on the
23rd February 1861.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOSEPH
WILSON, of Birmingham, in the County of Warwick, Manufacturer, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her-Letters
Patent, bearing date the Twenty-ninth day of August, in the year of our Lord
One thousand eight hundred. and sixty, in the. twenty-fourth year of Her.
reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said Joseph Wilson, Her special licence that I, the said Joseph Wilson,
my executors, administrators,, and assigns, or such others as I, the said
Joseph. Wilson, my executors, administrators, and assigns, should at any time
agree with, and no others, from time to time and at all times thereafter
during the term therein expressed, should and lawfully might make, use,
exercise, and vend, within the United Kingdom of Great Britain and Ireland,
the Channel Islands, and Isle of Man, an Invention for "A NEW, OR
IMPROVED WARM BATH," upon the condition. (amongst others) that. I,. the
said Joseph Wilson, my executors, or administrators, by an instrument, in
writing, under my, or their, or one of their hands and seals,.should particularly
describe and ascertain the nature. of the said Invention; and in what manner
the same was to be performed, and cause the same to. be filed in the Great
Seal Patent Office within six calendar months next.and immediately after the
date of the said Letters Patent.
.
NOW KNOW YE, that I, the said Joseph. Wilson;.do hereby declare. the
nature of the said Invention, and in what manner. the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement thereof, that is to say:―
My Invention consists of the new or improved warm bath constructed' in
the manner herein-after explained, and illustrated. in. the accompanying

page_text: Drawing, the essential novelty in which consists of a portable or moveable
fire-box or grate for heating the water in the bath, as herein-after particularly
explained.
Figure 1 represents in longitudinal vertical section a warm bath made
according to my Invention; Figure 2 represents the same in side elevation;
and Figure 3 represents the same in plan; Figure 4 represents an end
elevation, and Figure 5 a transverse vertical section of the said bath, the said
section Figure 5 being taken through the line a, Figure 2. The same letters
of reference are used to indicate the same parts in the several Figures of the
Drawing. The body 6 of the bath is made, by preference, of sheet metal, and
has the same general shape as the ordinary warm bath. The true bottom c of
the bath has the form indicated in Figures 1, 3, and 5, and over the said true
bottom c is a perforated false bottom d, represented in Figure I, and indicated
by dotted lines in Figure 5. In the channel e of the true bottom c, and
beneath the false bottom d is a flue f, which said flue opens into the chamber g
in the front end of the bath. The said chamber g is formed by the expanded
end of the flue f, the upper side of the 'said flue finclining upwards at. the
front end of the bath, so as to rise to about two-thirds the height of the bath,
as best seen in Figure 1. The upward inclination of the top of the flue f
sets in at about one quarter the length of the bath. A portable grate or
fire-box.h, to the under part of which an ash-pan i is fixed, may be inserted in
the chamber g and removed therefrom at pleasure by means of the knobs.or
handles on the ash-pan'i. The end f* of the flue fis inclined upwards, and
may be lengthened by a piece of ordinary stove piping being fixed thereon, the
said end, or the stove piping fixed thereon, being introduced into the
chimney of the room.in which the bath is used, or inserted in any other flue.
In using the bath, it is filled to the required height with water, and the
portable grate and ash-pan.h and i having been removed from the chamber 9,
and ignited fuel having been placed in the said fire-box or grate h, the said
fire-grate and ash-pan h, i, are replaced in the chamber 9. The heated air
and products of combustion from the ignited fluel 2 pass along the flue ƒ and
escape from the end into the chimney or other means of exit provided
therefor. The fluef and chamber 9 become thereby heated, and communicate
their heat to the water-m in the bath, the said.flue fand: chamber 9 being
completely surrounded by the water. The fire-box or grate h is provided with
a door n, at which the fire can be supplied with fuel, and the draught through
the fire regulated. As the fluef passes through the lower part of the bath,
the heat which it communicates to the water occasions a circulation in the said
water, which causes it to be rapidly and uniformly heated. When the

page_text: temperature of the water in the bath has been raised to the required degree,
the portable fire-box-and-ash-pan h, 'i, åre removed by the knobs-k, k, and the
bath is then ready for use.
In order to empty, the "bath, 'a' tap or stop-cock ò is fixed in its side, and the
greater part of the water may be drawn from the bath through the said tap or
stop-cock, the said tap or stop-cock being fixed' at such a height that an
ordinary bucket can be placed under it. The water is emptied from the lower
part of the bath and from the channel e by means of a plug or valve at p.
By raising the plug p from.the hole in the bottom of the channel e (which can
be effected through a hole in the perforated false bottom d) the water from
the lower part of the bath and the said channel e' passes into a tray or
drawer. q, .working in the slide.r underneath the bath. By drawing out' the
tray. by means of the knobs 5, s, it may be emptied. The said tray q is
represented partly withdrawn in Figure 3. The bath may be used as an
ordinary cold bath when it is not wanted as a warm bath.
Having now described the nature of my Invention, and the manner of
carrying the same into effect, I wish it to be understood that I do'not limit
myself to the precise details herein described, as the same may be varied
without departing from the nature of my Invention; but I claim as my
Invention the new or improved warm bath constructed in the manner herein-
before described, and illustrated in the accompanying Drawing; that is to say,
a warm bath having a portable fire-box or grate, the several parts of the bath
being constructed and arranged essentially in the manner described' and
represented.
In' witness- whereof, I, the said Joseph Wilson; have "hereunto set my
hand and seal, this Twenty-second day of February, in the year of
our Lord One thousand eight hundred and sixty-one.
Witness,
GEORGE SHAW.
JOSEPH WILSON. (L.s.)
