“IMPROVEMENTS IN BATHING APPARATUS AND VAPORIZING APPARATUS FOR

PIPES [A communication to him from abroad by William Woodward Rosenfield
of New York United States Mechanic.]
In Letters Patent N° 4112 of 1882 applied for on the 29th day of August 1882
the Invention described an ordinary bath tub provided with a longitudinal spray or
shower pipe so arranged that the shower will extend over the greater portion of
the body of the bather when recumbent in the tub. In that Patent I also
described a detachable Siamese connection by which the ordinary hot and cold
water cocks of the bath tub may be utilized to supply water to the shower or
spray pipe.
The present Invention is designed among other things to effect certain improve-
ments upon the apparatus therein described by which said apparatus is capacitated
to administer a steam or vapor bath as well as a shower bath, and also by which

page_text: the vapour generated may be tinctured or medicated so as to be used not only for
medical bathing but for inhalation or for disinfecting purposes.
The Invention also embraces certain improvements by which the devices for
connecting the shower pipe to the ordinary smooth cocks of a bath tub are
simplified and cheapened.
The bath tub is in the present case, as in the Patent referred to, of any ordinary
or approved form, and is provided at a point near the top with a longitudinal
shower or spray pipe which may, as also set forth in the Patent referred to, be
permanently attached to or made integral with the tub, or be loosely supported so
as to be removed when not required for use. This pipe, which extends nearly or
quite the entire length of the tub so as to administer a shower along the entire
length of the body of the recumbent bather, is connected by a flexible branched
pipe with the hot and cold water cocks from which it receives water.
When cold or tepid water is allowed to pass into the pipe it will flow through
the perforations in said pipe and fall to the bottom of the tub in a large number
of jets or in the form of spray, but I have discovered that when water of the
temperature usually formed in the hot water pipes of ordinary dwelling houses is
allowed to pass into the pipe and through its perforations (said perforations being
quite small) it will be largely converted into steam or vapor, which vapor will, if
confined within reasonable limits, be sufficiently hot for the purposes of a vapor
bath.
--For the purpose of confining the vapor generated in the manner just stated,
the bath tub is provided with a flexible cover of rubber cloth or other suitablo
material, which extends over its entire top and is hooked, buttoned or otherwise
.suitably fastened around the edge of the tub, or it may be allowed to fall loosely
over the edges of the tub, this cover being provided at a proper point with an
opening for the neck of the bather. This flexible cover may be made in two
parts, one part being stretched flat over a portion of the length of the tub, and the
other being in the forin of a cape fitting around the neck of the bather and
falling over the edge of the tub and onto the flat portion of the cover.
For the comfort of the bather the tub is provided with a removable seat of
any convenient form, to which is attached a foot rest which latter supports the
feet of the bather a short distance from the bottom of the tub and prevents them
from being scalded by the hot water which accumulates therein.
It will readily be seen that, were the hot water, when a vapor bath is being
taken, allowed to flow the whole length of the perforated pipe, not only would an
unnecessary amount of water be used; but the jets issuing from the perforations
would strike against and scald the body of the bather. To obviate this difficulty
the pipe is provided with a cock located a short distance say twelve or eighteen
inches from the ingress end, by which, when steam or vapor is to be generated, the
hot water can be shut off from all but a short section of the pipe. When the
water is reasonably hot the small amount issuing from the perforations in this
short section of the pipe will be sufficient to produce all the steam or vapor required
for bathing purposes, while at the same time the hot water will be economized
and the body of the bather protected.
When a vapor bath is to be taken the bather will place himself upon the seat
and having put his head through the opening and secured the cover around-the
edge of the tub, will allow the hot water to pass into the short section of the
spray pipe and out through its perforations until the tub is filled with steam
, or vapor. The water may be allowed to flow along as the bather remains in the
bath or it may be shut off whenever the vapor in the tub rises to the required
temperature.
In the treatment of many cutaneous and other diseases it is often desirable
that the patient should bathe in a vapor or in water tinctured with some medicinal
matter.
It is also frequently desirable, especially during or after sickness, to fumigate
houses or particular rooms thereof for the purpose of purifying them and preventing

page_text: contagion. This can be most effectively done by the use of a vapor tinctured
with or carrying some disinfectant, as a vapor is the only vehicle which is capable
of carrying such disinfectant into all the parts and interstices of the building
or room. The same principle is adopted in the treatment of various diseases, such
as catarrh, diphtheria and the like, when the patient is required to inhale a vapor
containing or medicated with some substance which it is desired to apply to the
diseased parts.
The present Invention also embraces an apparatus by which the vapor generated,
in the manner herein before set forth, can be medicated or tinctured with the
disinfectant or the substance possessing the medicinal properties required. Said
vapor to be used for bathing as just described or allowed to escape for inhaling or
disinfecting purposes.
The apparatus for this purpose is located at some convenient point between the.
hot water cock and the perforated spray pipe and is so arranged and operated that
as the hot water passes to the perforated pipe it is caused to come in contact or
mingle with the disinfectant or medicinal mattor so that the vapor where generated
will bo tinctured with the same.
The principal feature of my tincturing or medicating apparatus consists in the
devices which are employed to feed the liquid disinfectant or other matter against
the pressure of the column of hot water, which devicos will now be described.
When it is desired that the apparatus shall be capacitated to medicate the vapor
generated with either a solid or a liquid substance, the hot water pipo commu-
nicates through the flexible connection with a receptacle which in turn commu-
nicates with the pipe. The bottom of the receptacle is closed by a scrow cap,
which upon being reinoved permits the solid substance with which the vapor is to
be medicated to be placed in the receptacle, after which the cap is restored to
position.
To the upper end of the receptacle there is attached by means of a screw con-
nection an air chamber to the top of which is attached a liquid receptacle of a size
equal to or somewhat smaller than the air chamber.
The top of the liquid receptacle is hermetically sealed by moans of a screw cap
or otherwise, said top being provided with a small aperture, closed by a screw cap,
which can be removed for the introduction of the liquid.
The passage between the air chamber and the liquid receptacle is closed by a
suitable stopper which is perforated to receive the seat of a lifting valve and an
air tube. The valve is operated by a rod which is screw threaded and extends
through a nut formed in the cap, its passage being made air tight by a suitable
stuffing box.
When the vapor is to be medicated with a solid substance, such substance will
be placed in the first receptacle, it being prevented from passing into the pipes by a
gauze lining of the receptacle, and the hot water will be permitted to pass from the
inlet pipe through the receptacle into the outlot pipe. In such passage some of the
substance will be taken up by the water, which will thus become medicated.
After passing into the outlet pipe the water will be forced outward through its
small perforations in a series of fine jets which jets of water upon coming into
contact with the air will be almost entirely converted into vapour. The vapor
thus generated will of course be medicated or tinctured with the substance con-
tained in the water. Vapor can thus be readily produced in any desired quantity
and can be used for bathing, or be permitted to fill the room or even the entire
house, when desired, for disinfecting.
When the vapor produced is to be medicated with a liquid substance, such
substance will be placed in the liquid receptacle and the valve will be raised to an
extent sufficient to permit the liquid to flow out as fast as may be desired.
It will readily be seen that when the water is admitted into the lower receptacle
its head or pressure would cause it to rise and mingle with the liquid in the
receptacle were it not for the body of air contained in the air chamber. This

page_text: '
body of air, as it cannot escape, will however effectually prevent the rise of the
water, and thus keep the liquid in the upper receptacle entirely isolated.
It will readily be understood, that, as soon as the liquid in the liquid receptacle
commences to pass out, its surface will be lowered thus causing the air contained
in the receptacle above it to expand whereby its pressure will be so reduced that,
unless compensated for, the pressure of the air from below will soon stop the flow
of the liquid.
This difficulty is overcome and an equilibrium in the pressure of the air above
and below the liquid maintained by means of the air tube which is of sufficient
length to reach above the surface of the liquid and thus afford a free communi-
cation between the air chamber and the air above the liquid in the liquid
receptacle. From this it results that there is no pressure from below to resist the
flow of the liquid and prevent it from passing freely downward to mingle with
the water, the rapidity of its downward flow being governed by the position of the
lifting valve.
The air chamber should be as large as or somewhat larger than the liquid
receptacle so that sufficient air can pass from it to fill said receptacle without
permitting the water to rise above the lifting valve seat.
The feeding apparatus herein described will also be found well adapted for
many other purposes when it is desired to feed a liquid against the pressure of a
liquid or a gas, as for example in supplying oil to the pistons and valves of pumps,
engines, &c.
Where the bath cocks have only plain or smooth nozzles I provide a nipple of
such form that the elastic flexible connecting pipe can be slipped over it to form
a water tight joint and having a broad smooth surface adapted to make a water
tight joint by abutting against the mouth of the cock, a plain annulus is then
passed over the-end or nozzle of the cock and secured in position a short distance
above the end of the cock by means of a set screw or screws. The plain annulus
is screw threaded upon its outside and the nipple is provided with an annular
shoulder from which construction it results that by the use of a simple interior
threaded annulus provided with a shoulder the nipple may be drawn and held
snugly against the end of the cock. It is of course to be understood that a
suitable annular packing, will be interposed between the nipple and the end of the
cock to ensure a tight joint under all circumstances. It is evident that if the
threaded annular is made sufficiently short, the plain annulus may be secured in
position so as to be just flush with the end of the cock.
To connect or disconnect the shower pipe, all that is required is to simply screw
or unscrew the threaded annulus. It will readily be seen that a coupling
apparatus of this character can be used in connection with a cock of almost any
size as a plain annulus suitable for a large sized cock can be used equally well
upon one of small size.
It is apparent that the means herein shown for connecting the flexible pipe to
the smooth end of the cock may be made useful for other purposes for example to
connect the pipes of different size or to other apparatus.

In Letters Patent No. 4112 of one thousand eight hundred and eighty two
granted on the twenty ninth day of August one thousand eight hundred and
eighty two I have shown an ordinary bath tub provided with a longitudinal spray
or shower pipe so arranged that the shower will extend over the greater portion of
the body of the bather when recumbent in the tub-In that Patent I have also
shown a detachable siamese connection by which the ordinary hot and cold water
cocks of the bath tub may be utilized to supply water to the shower or spray pipe.
The present invention is designed among other things to effect certain improve-
ments upon the apparatus therein shown, by which said apparatus is capacitated to
administer a steam or vapor bath, as well as a shower bath, and also by which the
vapor generated may be tinctured or medicated so as to be used not only for
medical bathing but for inhalation or for disinfecting purposes.
The invention also embraces certain improvements by which the devices for
connecting the shower pipe to the ordinary smooth cocks of a bath tub are simplified
and cheapened.
To these ends the invention consists in various details of construction and
combinations of parts hereinafter fully described and particularly pointed out
In the accompanying drawings which fully illustrate the invention :-
Figure 1. is a longitudinal vertical section of an ordinary bath tub embodying
one feature of the invention.
Figure 2 is a cross section of the same.
Figures 3. 4 and 5 show the devices for connecting the spray pipe to the ordinary
smooth cocks of a bath tub.
Figure 6 is a sectional view of the medicating or tincturing apparatus showing
particularly the devices for feeding a liquid against the pressure of a column of
liquid or gas
Figure 7 is a modification to be hereinafter referred to
Figure 8 is a sectional view showing the spray pipe and medicating apparatus
used in connection with an ordinary stationary wash basin, the latter being
provided with a cover having an opening through which the vapor generated can
be inhaled.
Figure 9 is a like view of the same, the cover being omitted and the spray pipe
located in an elevated position and
Figure 10 is a detail to be hereinafter referred to.
The bath tub is in the present case, as in the Patent referred to, of any ordinary
or approved form, and is provided at a point near the top with a longitudinal
shower or spray pipe 3, which may, as also set forth in the Patent referred to, be

page_text: permanently attached to or made integral with the tub, or be loosely supported so
as to be removed when not required for use. This pipe, which extends nearly or
quite the entire length of the tub so as to administer a shower along the entire length
of the body of the recumbent bather, is connected by a flexible branched pipe 0
with the hot and cold water cocks 1-2 from which it receives water.
When cold or tepid water is allowed to pass into the pipe 3 it will flow through
the perforations in said pipe and fall to the bottom of the tub in a large number of
jets or in the form of spray, but I have discovered that when water of the
temperature usually found in the hot water pipes of ordinary dwellinghouses is
allowed to pass into the pipe 3 and through its perforations (said perforations being
quite small) it will be largely converted into steam or vapor, which vapor will, if
confined within reasonable limits, be sufficiently hot for the purposes of a vapor
bath.
For the purpose of confining the vapor generated in the manner just stated, the
bath tub is provided with a flexible cover 17 of rubber cloth or other suitable
material, which extends over its entire top and is hooked, buttoned or otherwise
suitably fastened around the edge of the tub, or it may be allowed to fall loosely
over the edge of the tub as shown in the present instance, this cover being
provided at a proper point with an opening 18 for the neck of the bather. This
Hexible cover instead of being arranged as shown, may be made in two parts, one
part being stretched flat over a portion of the length of the tub, and the other being
in the form of a cape fitting around the neck of the bather and falling over the
edge of the tub and onto the flat portion of the cover.
For the comfort of the bather the tub is provided with a removable seat 19 of
any convenient form to which is attached a foot rest 20 which lattor supports the
fect of the bather a short distance from the bottom of the tub and prevents them
froin being scalded by the hot water-which accumulates-therein.
It will readily be seen that where the hot water, when a vapor bath is being taken
allowed to flow the whole length of the perforated pipe 3, not only would an
unnecessary amount of water be used but the jets issuing from the perforations
would strike against and scald the body of the bather-To obviate this difficulty
the pipe 3 is provided with a cock 21 located a short distance say twelve or
eighteen inches from the ingress end by which when steam or vapor is to be
generated, the hot water can be shut off from all but the short section 22 of the
pipe. When the water is reasonably hot the small amount issuing from the
perforations in this short section of tho pipe will be sufficient to produce all the
steam or vapor required for bathing purposes while at the same time the hot water
will be economized and the body of the bather protected.
When a vapor bath is to be taken the bather will place himself upon the seat 19
and having put his head through the opening 18 and secured the cover around the
edge of the tub will allow the hot water to pass into the section 22 of the spray
pipe and out through its perforations until the tub is filled with steam or vapor-
The water may be allowed to flow as long as the bather remains in the bath or it
may be shut off whenever the vapor in the tub rises to the required temperature.
In the treatment of many cutaneous and other diseases it is often desirable that
the Patient should bathe in a vapor or in water tinctured with some medicinal
matter.
It is also frequently desirable especially during or after sickness, to fumigate
houses or particular rooms thereof for the purpose of purifying them and preventing
contagion. This can be most effectively done by the use of a vapor tinctured with
or carrying some disinfectants as a vapor is the only vehicle which is capable of
carrying such disinfectant into all the parts and interstices of the building or room.
The same principle is adopted in the treatment of various diseases such as catarrh,
diptheria and the like, when the Patient is required to inhale a vapor containing or
medicated with some substance which it is desired to apply to the diseased parts.
The present invention also embraces an apparatus by which the vapor generated
in the manner hereinbefore set forth can be medicated or tinctured with the

page_text: disinfectant or the substance possessing the medicinal properties required, said
vapor to be used for bathing as just described or allowed to escape for inhaling or
disinfecting purposes.
The apparatus for this purpose is located at some convenient point between the.
hot water cock and the perforated spray pipe and is so arranged and operated that
as the hot water passes to the perforated pipe it is caused to come in contact or
mingle with the disinfectant or medicinal matter so that the vapor when generated
will be tinctured with the same.
The principal feature of my tincturing or medicating apparatus consists in the
devices which are employed to feed the liquid disinfectant or other matter against
the pressure of the column of hot water, which devices will now be described,
reference being had to figure 6 of the drawings.
When it is desired that the apparatus shall be capacitated to medicate the vapor
generated with either a solid or a liquid substance it will be constructed as shown
in said Figure.
Referring now particularly to that Figure it will be observed that the hot water
pipe communicates through the flexible connection 6 with a receptacle 23; which in
turn communicates with the pipe 3. The bottom of the receptacle 23 is closed by
a screw cap 24 which upon being removed permits the solid substance with which
the vapor is to be medicated to be placed in the receptacle, after which the cap is
restored to position.
To the upper end of the receptacle 23, there is attached by means of a screw
connection 25, an air chamber 26, to the top of which is attached a liquid receptacle .
27 of a size equal to or somewhat smaller than the air chamber
The top of the receptacle 27 is hermetically sealed by means of the screw cap 28,
or otherwise, said top being provided with a small aperture 29, closed by a screw
cap 30 which can be removed for the introduction of the liquid.
The passage between the air chamber and the liquid receptacle is closed by a
suitable stopper 31 which is perforated to receive the seat 32 of the valve 33 and
the air tube 34. The valve 33 is operated by a rod 35 which is screw threaded and
extends through a nut formed in the cap 28 its passage being made air tight by a
suitable stuffing box 36.
When the vapor is to be medicated with a solid substance, such substance will
be placed in the receptacle 23, it being prevented from passing into the pipes 6-3
by the gauze lining 37 of the receptacle and the hot water will be permitted to
pass from the pipe 6 through the receptacle into the pipe 3. In such passage some
of the substance will be taken up by the water which will thus become medicated-
After passing into pipe 3. the water will be forced outward through its small per-
forations in a series of fine jets, which jets of water upon coming into contact with the
air will be almost entirely converted into vapor. The vapor thus generated will
of course be medicated or tinctured with the substance contained in the water.
Vapor can thus be readily produced in any desired quantity and can be used for
bathing or be permitted to fill the room or even the entire house when desired
for disinfecting.
In Figure 7 an apparatus is shown which is adapted to act with solids only the
air chamber and liquid receptacle being removed and the upper end of the receptacle
23 closed by a cap 38.
When the vapor produced is to be medicated with a liquid substance such
substance will be placed in the receptacle 27. and the valve 33 will be raised to an
extent sufficient to permit the liquid to flow out as fast as may be desired.
It will readily be seen that when the water is admitted into the receptacle 23 its
head or pressure would cause it to rise and mingle with the liquid in the
receptacle 27 were it not for the body of air contained in the chamber 26. This
body of air as it cannot escape will however effectually prevent the rise of the
water and thus keep the liquid in the upper receptacle entirely isolated.
It will readily be understood that as soon as the liquid in the receptacle 27
commences to pass out, its surface will be lowered thus causing the air contained in

page_text: the receptacle above it to expand whereby its pressure will be so reduced that
unless compensated for the pressure of the air from below will soon stop the flow of
the liquid.
This difficulty is overcome and an equilibrium in the pressure of the air above
and below the liquid maintained by means of the tube 34 which is of sufficient
length to reach above the surface of the liquid and thus afford a free communication
between the chamber 26 and the air above the liquid in the receptaclo 27.
From this it results that there is no pressure from below to resist the flow of the
liquid and prevent it from passing freely downward to mingle with the water, the
rapidity of its downward flow being governed by the position of the valve 33.
As before stated the chamber 26 should be as large as or somewhat larger than
the receptacle 27 so that sufficient air can pass from it to fill said receptacle
without permitting the water to rise above the valve seat 32.
It is to be remarked that it is not necessary that the tube 34 should be upon the
interior of the receptacle 27. It may be upon the outside, and so located as to pass
through the walls of the chamber 26 and the receptacle 27 above the surface of the
liquid in the latter.
In Figure 8 the invention is shown as embodied in a different form and used in
connection with an ordinary stationary wash bowl, as 39 so as to produce an
inhaling as well as a vaporizing apparatus.
In this case the air chamber instead of being placed above the receptacle 26 is
located at one side the two being connected by a short pipe 40. The apparatus
thus organised is supported in any convenient position near the wash bowl and the
perforated pipe 3 bent to an annular form is by any convenient form of bearing as
41 loosely supported in or just above the bowl. In this case the hot water
spigot 2 is connected by a flexible pipe 42 with the air chamber 26 and the
perforated pipe 3, by a like pipe 43. is connected with the receptacle 23.
The parts being thus connected and the spigot-2 turned so as to allow the hot
water to flow, the operation of the apparatus will be the same as already set forth
in connection with Figure 6.
When it is desired to inhale the vapor the bowl will be provided with a cover 4+,
having a suitably shaped aperture 45 above which the Patient can hold his face so
as to draw the vapor into his mouth and nostrils.
If it should at any time be desired to medicate water for bathing with any
substance it can be readily done with this apparatus by connecting the pipe 43, to
the hot or cold spigot according to which is desired and disconnecting the pipe 43
from the pipe 3 so as to allow the water to run freely into the bowl or tub.
If it is desired to arrange the apparatus so that it can be used independently of
the spigots it can be done by connecting the hot and cold water pipes by a cross
pipe as 46, controlled by cocks as 49. and provided with a branch as 48 to which
the pipe 42 can be connected all as shown in dotted lines in Figure 14.
The pipes may, if desired, be permanently attached to the bowl by a series of
brackets 41. as shown in Figure 9.
When the production of vapor for disinfecting purposes is all that is desired, the
position of the pipe 3. is not material. One convenient position is that shewn in
Figure 9 in which it is shown as removed from the bowl and supported in
brackets. When in this position it can be also used for administering a shower or
spray bath.
When the pipe 3 is so located that its drippings cannot be caught by the wash
bowl or bath tub, it will of course be necessary to provide a suitable trough or
dish for that purpose.
In the structure shown in Figure 9 the valve and valve rod 33. 35 are
dispensed with and a stop cock 50 is used to control the passage between the
air chamber 26 and the liquid receptacle 27, to regulate the feed of the liquid.
The feeding apparatus herein shown and described will also be found well
adapted for many other purposes when it is desired to feed a liquid against the
pressure of a liquid or a gas, as for example in supplying oil to the pistons and

page_text: valves of pumps, engines, et cetera. I therefore claim this apparatus broadly
regardless of the use to which it is applied.
;
The perforated pipe 3. may as already stated, be made integral with or
permanently attached to the bath tub, in which case it may communicate with tho
hot and cold water pipes by permanent connections, but it will more frequently be
found desirable particularly as this apparatus is especially adapted for application
to tubs already set, to have the pipe 3, so supported that it can be readily secured,
and to detachably connect it by a flexible pipe, as shown with the usual hot and
cold water cocks. When these cocks are provided with screw threaded nozzles such
connection can be readily made by an ordinary coupling.
These cocks more frequently however, have only plain or smooth nozzles and to
make a temporary.connection in such case I provide a nipple 10, of such form that
the elastic flexible connecting pipe 6 can be slipped over it to form a water tight
joint as shewn in Figures 3 and 4 and having a broad smooth surface 11 adapted
to make a water tight joint by abutting against the mouth of the cock. A plain
annulus 12 is then passed over the end or nozzle of the cock and secured in position
a short distance above the end of the cock by means of a set screw or screws 13.
The annulus 12 is screw threaded upon its outside and the nipple 10 is pro-
vided with an annular shoulder 14 as clearly shown in Figure 4 from which
construction it results that by the use of a simple interior threaded annulus 15
provided with a shoulder 16. the nipple may be drawn and held snugly against the
end of the cock. It is of course to be understood that a suitable annular packing
will be interposed between the nipple and the end of the cock to ensure a tight
joint under all circumstances. It is evident that if the annulus 15 is made
sufficiently short, the annulus 12 may be secured in position so as to be just flush
with the end of the cock.
To connect or disconnect the shower pipe, all that is required is to simply screw
or unscrew the annulus 15; It will readily be seen that a coupling apparatus of
this character can be used in connection with a cock of almost any size as an
annulus 12 suitable for a large sized cock can be used equally well upon one of
small size.
″
It is apparent that the means herein shown for connecting the flexible pipe 6. to
the smooth end of the cock may be made useful for other purposes than that herein
shown as for example to connect pipes of different size.
By means of the provisions heroin described a simple bath tub is made to afford
facilities not only for ordinary bathing but for a shower or spray bath a vapor or
a medical bath and for providing vapor for inhaling and disinfecting purposes
