AN IMPROVEMENT IN BATHS
Year: 1863

page_text: LETTERS PATENT to David Dunne Kyle, of Victoria Street, Westminster,
for the Invention of "AN IMPROVEMENT IN BATHS."
Sealed the 17th December 1863, and dated the 20th June 1863.
PROVISIONAL SPECIFICATION left by the said David Dunnė Kyle at
the Office of the Commissioners of Patents, with his Petition, on the
20th June 1863.
I, DAVID DUNNE KYLE, of Victoria Street, Westminster, do hereby declare
the nature of the said Invention for "AN IMPROVEMENT IN BATHS," to be as
follows:-
My Invention consists in disturbing or agitating the water in a bath by
means of the pressure or expansion of air forced or allowed to escape or to
ascend through it. The usual mechanical or other known means for blowing
or forcing air may be applied to or connected with the bath by tubes or air
chambers opening into it through one or more apertures or perforations. An
individual using the bath, or an attendant, may work the blowing or forcing
apparatus, or.steam or other power may be used for the purpose, as in the
case of swimming baths or of several baths in connection. Compressed air
may be stored in reservoirs or vessels by hydraulic pressure or other power,
from whence to be allowed to escape through the bath; heated or cooled air
may be used where required.

by the said David Dunne Kyle in the Great Seal Patent Office on the
19th December 1863.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, DAVID
DUNNE KYLE, of Victoria Street, Westminster, in the County of Middlesex,
send greeting.
•
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twentieth day of June, in the year of our Lord
One thousand eight hundred and three, in the twenty-seventh year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto
me, the said David Dunne Kyle, Her special licence that I, the said David
Dunne Kyle, my executors, administrators, and assigns, or such others as I,
the said David Dunne Kyle, 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 "AN IMPROVE-
MENT IN BATHS," upon the condition (amongst others) that I, the said David
Dunne Kyle, 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 David Dunne Kyle, do hereby declaré
the nature of my said Invention, and in what manner the same is to be
performed, to be particularly described and ascertained in and by the follow-
ing statement, that is to say :-
My said.Invention consists in disturbing or agitating the water in a bath
by means of the pressure or. expansion of air forced or allowed to escape
or to ascend through it. I.may.:observe, in: the first place, that it is unneces
sary to give any description of the bath or baths to which this Invention would
be applied, as its application does not involve any different construction in
paths as they are at present, or may be ordinarily erected or manufactured ;
and, in the second place, as the machines, apparatus, or engines for forcing or
blowing air, or the means of compressing and storing it by hydraulic pressure
or otherwise, all which may be or are in ordinary use or known, would be

page_text: avaliable for application to this Invention, it is not necessary to describe
such here.
The Invention relates to the disturbance or agitation of the water in a bath,
and in order to ascertain more clearly its nature, reference may be had to the
accompanying Drawing and to the letters thereon, in which A is to be taken
as representing a bath of any shape, size, or construction. In cases where the
air blowing or forcing apparatus or machinery is on a lower level than the
water in the bath, as at D, which is to be taken as representing such. appara-
tus or machinery, E is a tube or tubes, extending from the latter into the
bath, through which the air is forced and discharged at any point or points in
the water. of the bath, as may be required; this.tube is to be carried in a bent
form, as in that of a syphon, over a higher point than the surface level of the
water in the bath, so as to prevent the water from flowing. out. In cases
where the.air blowing or. forcing apparatus or machinery is on a higher level
than the bath, as at B, which is to be taken as representing such apparatus
or machinery, C is a tube or tubes extending from the latter into the bath, to
be discharged as before, but which may enter at any point without the syphon
form of E. The orifices of these tubes may be fixed at one or different parts
of the bath as required, or the tubes may be flexible, so as to be directed to
any points at pleasure. F, F, F, represent an air chamber or chambers, into
which the tubes C or E may be made to enter, the air in that case being dis-
charged into the water through perforations in the inner sides of the chambers
F, E, F, which would form the bottom or sides of the bath.
Where the air is first compressed or stored in chambers, stop-cocks are
to be connected with the tubes so as to allow. the air to escape only when
required.
In cases where heated air is used, the blowing or forcing apparatus or ma-
chinery is placed in a heated apartment or chamber, or is connected therewith
by a tube or other ordinary arrangement, or a tube passing through a fire so
as to warm the air in its passage may be made to supply the blowing or
forcing apparatus.
Where cooled air is used, the blowing or forcing apparatus or machinery
is placed in an ice well or cooled apartment or chamber, or connected there-
with by a tube or other ordinary arrangement.
In all cases, except where otherwise required, the machines, apparatus, or
engines for blowing or forcing air are to be placed or erected in positions
apart from the bath rooms, the tubing which conducts the air being fixed.or
temporarily placed as in the usual manner for other purposes.

page_text: Having now. described and particularly ascertained the nature of my said
Invention, and the manner in which the same is or may be used or carried
into effect, I would observe, in conclusion, that I do not confine or restrict
myself to the precise details. or arrangements which I have had occasion
to describe or refer to, as many variations may be. made therefrom without
deviating from the principles or main features of my Invention; but what I
consider to be novel and original, and therefore claim as the Invention secured
to me by the herein-before in part recited Letters Patent, is, the disturbing or
agitating the water in a bath by means of the pressure or expansion of air
forced or allowed to escape or to ascend through it.
In witness whereof, I, the said David Dunne Kyle, have hereunto sėt
my hand and seal, the Twentieth day of December, One thousand eight
:. hundred and sixty-three.
