Improvements in and relating to Baths.
1. WILLIAM HEALTH
How, Lanarkshire,
Manufacturer, do hereby declare the nature of my invention to be as follows :—
This invention has reference to and comprises a new or improved construction or
arrangement and combination of the parts of a portable hath and its pressure and
water supply fittings, which will be more simple, convenient, and useful than such
baths heretofore in use.
The improvements essentially consist in the combination of a portable bath with
water and air pressure supply vessel and pump, for producing the supply of
pressure water to the bath part of the arrangement to give a -pray, shower, douche,
or other equivalent bath effect as hereinafter described.
Under one arrangement the portable bath would consist of a derp edge water
retaining tray, preferably circular on which the per-on would stand to bath, with
strong bended rin above and strengthening ribs below, and a deep ring canopy
above with strengthening beads supported on three or other number of portable
bars or tubular columns carried in sockets in the basement water tray and upper
canopy. A "mackintosh" or circular water proof curtain would be mounted by
wire, hooks, or otherwise to hang on the lower inner bead of the canopy all round,
down to near the basement tray, with a laced slit up one side for entering or
retiring from within this water-proof screened bath. The water supply vessel
would under one construction consist of a close portable fluid tight vessel of round
or other convenient shape preferably formed of sheet iron or steel, welded or
riveted and galvanized, painted, or enamelled, and fitted in the centre with a small
reciprocating hand air pressure pump reciprocated by a cross arm above so as to
force pressure air over the top of the water to force it through the bath pipes and
fittings, the vessel being preferably fitted with a pressure guage; the water being
previously filled into the vessel through a suitable screw socket, preferably at one
side near the top with cap or plug screwed on before working the pressure pump,
and having a tube leading down to the bottom of the vessel so as to see at once
when the water in the vessel was filled in to a proper level. A water branch would
be taken off from the lower part of the water vessel, or it might be from the top of
this filling socket branch which leads to the bottom of the vessel to which a flexible
or swivelled coupled rigid pipe would be attached, and preferably be led up one of
the columns within the bath, and be attached to an inlet branch of a tubular metal
cross or other branch service pipe with taps leading to the several bath fittings,
and with a main or common cock or tap for shutting off or putting on the pressure
water from the air pressure cistern to all the bath jet fittings. This cross or other
metal bath service pipe would be secured at a proper height by a hand screw to
one of the columns, with metal tubular branches fitted with the different bath
arrangements, that is one with a perforated rose or other spray jet arrangement, for
giving a spray bath, or another with a nozzle for giving a douche bath, both with
swivel joints at a suitable height to give these baths to the chest, back, or other
part of the body; and a third rising tube with tap, also near the hand, curving up
over the centre of the canopy, having a perforated shower bath arrangement at its
end, or fitted on the top of the canopy, so as to give a shower bath in the centre
over the head of the person when its hand tap or valve was opened. Or otherwise
in some cases one four-way valve chest arrangement with four branches and ports
leading to the different branches and jets of the bath fittings may be used, so that
by turning this tap or valve to any one of the four positions any of the desired
baths can be obtained by this single four-way tap or valve, instead of having a

page_text: separate tap or valve for each bath arrangement. And although the water pressure
and air forcing vessel has been described as portable and separate from the base-
ment tray basin of the bath, it is to be understood that it may be constructed in
one with this tray by forming the water and air vessel under the tray or at one
side of it, as a seat within the waterproof screen; and when this vessel is formed
under the tray, the latter would be strengthened by cross ribs to support the
weight of the person and the necessary air pressure within, and in this case the air
pump may lie horizontally and be worked by a vertical lever fulcrumed on a
bracket at the side of one of the columns. In some cases, as for use in camps where
bell or other tents are used, only the water foot tray and tank might be required
placed within the tent and the bath branch fittings and tap be all mounted on the
water air pressure forcing tank connected to it by rigid branch tubes on ball or
other swivel joints for use without the canopy and waterproof curtain or necessity
for the flexible pipes.

COMPLETE SPECIFICATION.
Improvements in and relating to Baths.
I, WILLIAM HENRI LUTHER, of Petershill Road, Glasgow, Lanarkshire,
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, that is to say :-
This invention has reference to and comprises a new or improved construction or
arrangement and combination of the parts of a portable bath, and its pressure and
water supply fittings which will be more simple, convenient, and useful, than such
baths heretofore in use.
The improvements essentially consist in the combination of a portable bath with
a water and air pressure supply vessel and pump, for producing the supply of
pressure water to the bath part of the arrangement to give a spray, shower, douche,
or other equivalent bath effect as hereinafter described.
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 have hereunto
appended an explanatory sheet of drawings, in which the same reference letters are
used to indicate corresponding parts in all the figures where shown.
Figure 1 is a perspective elevation of one arrangement of portable bath as
constructed in accordance with my improvements, and shown as it would be in
practice.
Figure 2 is a sectional elevation of one arrangement of hand air pump for
supplying pressure water to the bath.
Figure 3 is a sectional elevation and Figure 4, a plan view of one construction
of a three way cock which would be coupled to the water supply pipe to give a
douche, jet, shower, or other supply of water to bath.
Referring to these drawings.-Under one arrangement as shown in these
drawings the portable bath consists of a deep edge water retaining tray A A',
preferably circular, on which the person would stand to bath as shown in Figure 1,
with strong beaded upward projecting rim A' and it may have strengthening ribs
below, and a deep ring canopy A above preferably made of tubular iron or steel
for strength and lightne supported on three or other number of portable bars or
tubular columns carried in sockets at Ain the basement water tray A and
screwed at A into the upper ring A. A mckintosh or circular waterproof
curtain B is mounted by wire rings or hooks B' or otherwise to hang from the top
canopy A all round, down into the basement tray A, with a laced slit up one side
for entering or retiring from within this water-proof screened bath; and all the

page_text: parts are capable of being easily taken down and packed. The water supply
vessel under one construction as shown in Figure 2 consists of a close portable fluid
tight vel C of round or other convenient -hape preferably formed of sheet iron
or -teel welded or rivette, and galvanized painted or enamelled, and titted outside
the bath A, with a small hand air forcing or pressure pump ( reciprocated by a
cross arm C above, or other equivalent so as to force pressure air over the top of
the water to force it through the bath pipe and fittings, the vessel C being
preferably fittel with a pressure guage (the water being previously filled int
the vessel through a suitable screw socket at C³ preferably at one side near the
top with cap or plug screwed on before working the pressure pump (and a tube
may be led down to the bottom of the vessel C so as to see at once when the water
was filled into the vessel to a proper level. A coupling water branch pipe ("
would be taken off at C from the lower part of the water vessel C to which a
light india-rubber or flexible pipe D would be attached by a coupling socket joint
at D. This flexible pipe D would be long enough to extend to the top or any
other part of the bath chamber, and would be fitted at its free end with bath
supply fittings to give any desired form of water bath, as douche, jet, or shower.
In the arrangement shown in Figures 1, 3, and 4, the bath supply fittings would be
connected to the india-rubber pipe D by a coupling socket joint at D", and would
consist of an inlet coupling branch D' attached to the service jet supply apparatus
consisting of two screw ground cocks and their cases E, E', the former E having a
two way port e in it, to serve the water either to the cock and chamber E', or to a
douche spray jet nozzle E", or shut the water supply off entirely at the branch D².
The cock E, has a three way port e' which either puts the water on to the column
jet nozzle E, or on to the spray or shower jet nozzle as shown in action in
Figure 1, or by a half turn of the cock shut the water supply off from both of these
jet nozzles E, E³. Instead of having a flexible pipe D for attaching to a portable
hand nozzle appliance as shown in Figures 1, 3, and 4, the water may be led from the
pump to a rigid pipe led up one of the columns A within the bath and attached
to an inlet branch of a tubular metal cross or other branch service pipe with taps
lending to the several bath fittings rigidly screwed or secured to the columns and
canopy and with a main or common cock or tap for shutting off or putting on the
pressure water from the air pressure vessel to all the nozzle bath jet fittings to give
the different baths, and which may have a separate cock for each of the nozzle
fittings. Or otherwise in some cases one three or four-way valve chest arrange-
ment with four branches and ports as used in ordinary baths may be employed
leading to the different branch nozzles and jets of the bath fittings, so that by
turning this tap or valve to any one of the three or four positions, any of the
desired baths can be obtained by this single three or four-way tap or valve, instead
of having a separate tap or valve for each bath arrangement.
Although the water pressure and air forcing vessel C has been described as
portable and separate from the basement tray basin A of the bath, it may be
constructed in one with this tray A, by forming the water and air vessel under the
tray A, or at one side of it, as a seat within the waterproof screen B; and when
this vessel is formed under the tray A, the latter would be strengthened by cross
ribs to support the weight of the person and the necessary air pressure within, and
in this case the air pump might lie horizontally and be worked by a vertical lever
fulcrumed on a bracket at the side of one of the columns.
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,―
First. The con-truction or arrangement and combination of the parts of a
portable bath with canopy and curtain, and air pressure and water supply fittings,
Substantially as herein described, in reference to and shown in the accompanying
drawings.
Second. The construction and use of a portable bath with basement-tray and

page_text: ring canopy above supported on columnus, and carrying a waterproof curtain,
substantially as herein described in reference to and shown in the accompanying
drawings.
Third. The combination with a portable bath of an air pressure vessel and air
pump for forcing the water to the bath fittings, substantially as herein described in
reference to and shown in the accompanying drawings.
