1, JOHN KIRKWOOD of 3 Crighton Place, in the city and county of Edinburgh,
Bath Manufacturer, do hereby declare the nature of this invention to be as follows:-
My invention has reference to special improvements in the construction and arrange-
ment of the parts of shower, douche, and spray baths, and especially of those in which
the sides of the enclosing spray case under the shower or donche canopy are made of
sheet zinc or other sheet metal, which improvements will make such baths more con-
venient and efficient, with little more labour or expense, than they have been as
heretofore constructed.
And the nature and novelty of my improvements consist all as follows:--The
top or crown of shower or spray bath would be more domed out of the sheet metal
than heretofore and formed with a flange all round its lower outer edge for jointing to
the sheet metal sides or case below. This canopy would be fitted much as usual with
the two couplings over the top, leading the water from their respective service pipes
to the shower bath receiver and perforated crown below; and to the douche jet in centre,
or where otherwise placed. Further by my improvements the sides of the enclosing
spray case, below the shower canopy and above the sides and end of the plunge bath,
would be formed of sheet zinc or other sheet metal, and have the vertical spray
recesses struck or embossed in a semi-circular form to project inwards within the case,
at all the positions round the cases where a spray tube was desired, and of a diameter
to form one half of these vertical spray tubes which would be perforated wherever the
spray was required. The other half of these spray tubes would be formed, inserted,
and soldered down the back of these embossed recesses right up to the top where they
all would be soldered and connected to a service tube fitted round the Hange of the
domed canopy joining and leading into the whole of these improved spray tubes, the

page_text: service coupling for the spray being connected to this upper circular tube round
the top.
When these improved perforated recesses were made deep enough in the sheet metal
of the case to form service spray tubes themselves, a strip of flat sheet zinc or other
metal might be soldered across the outside of the recesses preferably with the edges
turned down into the sides of the said spray grooves formed within the sheet metal
sides of the bath, and soldered down the two joints outside, thus saving the necessity
for making these as soldered half tubes. The water to the several service tubes of the
spray, shower and douche baths is controlled by the usual valves and taps in front of
the zinc case of the canopy.
These improvements would also be applicable to other forms or constructions of
spray baths, when formed of zine or other sheet metal sides.

page_text: I, JOHN KIRKWOOD, of 3 Crighton Place, in the City and County of Edinburgh'
Bath Manufacturer, do hereby declare the nature of my invention and in what manner
the same is to be performed, to be particularly described and ascertained in and by the
following statement in writing, reference being had to the accompanying sheet of
Drawings, and to the letters and figures marked thereon, that is to say :-
My said Invention has reference to special improvements in the construction and
arrangement of the parts of shower, douche, and spray baths, and especially of those
in which the sides of the enclosing spray case under the shower or douche canopy are
made of sheet zinc or other sheet metal; which improvements will make such baths
more convenient and efficient with little more labour or expense than they have been
as heretofore constructed.
And in order that my said Invention and the manner of performing or carrying the
same into effect or practice may be properly understood, I hereunto appended an
explanatory Sheet of Drawings, in which the same reference letters are used to indi-
cate corresponding parts in all the Figures where shown. Figure 1 is a perspective
elevation of a plunge, spray, shower, douche and wave bath, as constructed with the
improvements of this Invention; and Figures 2 and 3 are respectively a vertical
section of the upper dome part A and the spray sides A2 of the bath, to show the
detailed construction and arrangement of these with the spray, shower and douche
supply water fittings a, a¹, B, B, C, C, all to a larger scale and to show these more
clearly than in the general view Figure 1 while Figures 4 and 5 show enlarged
sectional elevations of two slightly different modes of forming the spray tubes a, a in
the wall-plates A² according to my improvements.
Referring to these Drawings, the nature and novelty of my improvements consist
all as follows:-The top or crown A of the shower or spray bath B B would be more
domed out of the sheet metal than heretofore and formed with a flange A¹ all round its
lower outer edge for jointing to the sheet metal sides or case A below. This canopy A,
would be fitted much as usual with the two couplings B and C over the top, leading the
water from their respective service pipes and valves B, C, to the shower bath receiver
and perforated crown B, B₁ below, and to the douche jet in centre, or where
otherwise placed. Further by my improvements the vertical sides A² of the enclosing
spray case, below the domed shower canopy A, A', and above the sides and end of the
plunge bath D, would be formed of sheet zine or other sheet metal, and have the
vertical spray recesses a struck or embossed in a semicircular form to project inwards
within the case vertically at all the positions round the casing, where a vertical spray
jet tube was desired, and of a diameter to form one half of these vertical spray tubes a
which would be perforated in front wherever the spray was required, as seen more
particularly in the enlarged broken side and end view Figure 4. The other half a of
these spray tubes would be formed, inserted, and soldered down the back of these
embossed recesses at a right up to the top where they all would be soldered and

page_text: connected through the flange A to an embossed or stamped service tube a³ or other
equivalent segmental tube fitted round and above this flange A of the domed canopy A
joining and leading into the whole of these improved spray tubes a a¹. The service
couplings B, C, for the spray and douche would be connected as seen in Figure 1, to
their respective service tubes and valves B² and C², mounted on the side or front
woodwork of the bath. This tube would be fitted with a coupling branch a
connected to its main service pipe as also seen in Figure 1. In some cases when
these improved perforated recesses a were made deep enough in the sheet metal of the
case A to form the service spray tubes themselves, a strip of flat sheet zinc or other
metal a might be soldered across the outside of the recess a, preferably with its edges
turned down into the sides of the said spray grooves a formed within the sheet metal
sides A, of the bath, as shown in Figure 5, and soldered down the two joints at a² out-
side as in Figure 4, thus saving and without requiring the necessity for making these
plates A, A2, soldered as half tubes as shown in the latter Figure 4.
When a wave
bath E is used, it would be fitted with a coupling branch E secured through the
central back of the vertical sides of the canopy A, at the proper height, as shown in
Figures 1 and 3, and have a service branch and valve E2 of its own. The water to
the several service tubes and couplings at B, C, and. E', of the spray shower and douche
baths is controlled by the usual valves and taps in front of the zinc case of the canopy
as shown in Figure 1.
These improvements would also be applicable to other forms or constructions of
spray baths, when formed of zinc or other sheet metal sides.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is
First. The general construction and arrangement of the parts of spray, or wave
baths, substantially as herein described in reference to and shown in the accompanying
Drawings.
Second. In spray baths, the forming of the spray tubes by indentations a in the
sides A of the bath, and filling these up with curved or flat enclosing tube plates A',
soldered and fitted within the main embossed parts a, substantially as herein described
in reference to and shown in the accompanying Drawings.
Third. In spray baths, the fitting of a segmental or supply water rim tube a³ and
its fittings a, a, round the canopy A A, for supplying the water to the spray
tubes a,, in the sides A2 of the bath, substantially as herein described in reference
to and shown in the accompanying Drawings.
Fourth. In spray baths, the making of the canopy A, A, domed, with its shower and
douche baths and fittings in centre, substantially as herein described in reference to
and shown in the accompanying Drawings.
