Improvements in Stoves for Heating Water, and in Hot Water
Appliances in connection therewith.
1, REGINALD WALTER BARKER, of Monument Chambers, King William Street,
Lune County or soudlesex, aten. Agent, u hereby declare the nature
of this invention and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement:-
This invention relates to hot water appliances primarily for use upon the
human body, and its principal features may be summarized as follows:-
First. The employment of a double chambered water containing vessel having
respectively an outlet and an inlet which connect with the two ends of a coil of
tubing, which is arranged for use upon the person in the manner of a hot water
bag, and means whereby the application of heat causes a continuous circulation of
water through the coil.
Second. In an apparatus comprising a double chambered vessel to contain water,
anu means whereby the application of heat causes water to circulate from one
chamber to the other through a connecting tube, said tube being formed into a coil
to serve as a hot water bag, the employment of a burner to heat one of the chambers
and a flame regulator upon said burner; a telescoping dome being inserted in the
other of said chambers, and adapted to rise with the accumulation of heated air, and
a connector between the flame regulator and the dome causing the movement of
the latter to be transmitted to said regulator, to diminish or increase the size of the
Hame.
Third. The formation of a hot water appliance to serve as a hot water bag, and
which comprises a doubled coil of tubing superimposed upon and secured to a
sheet of rubber, the ends of said coil uniting with tubes which form a hot water feed
and return, the unions consisting of short pieces of stiff tubing having eyelets which
enable the tubing to be attached to a stationary object, by pinning, sewing, etc.
Fourth. Certain details of construction in the apparatus to be described herein,
rendering the same practical, efficient, and cheap to manufacture.
In the drawings accompanying this application,
Figure 1 represents a vertical sectional view of my apparatus.
Figure 2 is a plan view of a coil of tubing forming a hot appliance and adapted
to connect with the apparatus, and
Fig. 3 is a section of the apparatus on the line 1-1 of Fig. 1.
In said Figures, A indicates a spirit lamp which also serves as a base or support
for the rest of the apparatus. Said spirit lamp has a burner tube a, into which is
loosely fitted a perforated cylinder a¹, which in turn contains a tube a², said
tube a² being of a sufficient diameter to frictionally hold a wick a³, above which wick
is placed a quantity of loose asbestos. The tube a rests upon the bottom a' of
lamp A, and its lower end is cut diagonally as seen, or otherwise shaped to expose

page_text: the wick to the spirit in the lamp. B is a sleeve which fits loosely over burner
tube a, and has a radial flange b, as seen. Said sleeve B is adapted to slide upon the
burner tube a to diminish the size of the flame. C is a rod pivotally held upon
the upper surface of lamp A by lug e, its inner end e¹ being bentsas seen to bear
against the under surface of flange so that when said rod C is turned by its
handle, the end portion el serves to raise the sleeve B to the desired extent.
1) indicates a piece of wire secured upon the lamp surface and arranged to be in
frictional contact with the bent end c¹ of rod C, and serving to retain the rod C in
the position to which it is turned.
E indicates a double chambered vessel mounted by legs e upon the lamp A, said
legs being secured in the following manner, to wit: One of said legs having a
foot portion bent at right angles thereto, is engaged thereby in a lug el, the opposite
leg which is similarly-bent, being adapted to slip under and .be held by a spring
clip e, which is secured upon the lamp. F, G, indicate respectively the lower and
upper chambers of the vessel E. The chambers F, G, are connected together by
tube-H; which-tube extends to the base of chamber F, where it is cut.diagonally..as
seen, to expose its interior; the upper end of said tube extending to within a short
distance from the upper end of tube G. An air space I exists between the
chambers.,.and G, said chambers, being made more rigidly united by connecting
pieces i, which are secured against the upper surface of chamber F and the lower
surface of chamber.G.
الورد
J indicates an outlet. nozzle leading from chamber G, and K indicates an inlet
nozzle connected to chamber F. Short lengths of tubing jk are connected
respectively to the nozzles J, K. Lindicates a coil of tubing which is superimposed
upon and secured to one side of a sheet of rubber M. The ends of said tubing,
which ends are of any suitable length, are arranged to be connected respectively
with the pieces of tubing j k by means of union N. Said unions consists of short
lengths of rigid tubing having the loops, whereby they may be secured-by
pinning, stitching, or otherwise, to a table, bed clothing, a table cloth, or some
other article adjacent to the user, the object of such connection being to prevent-the
movement of the user from operating to turn over the lamp and vessel.
O indicates a dome which is fitted loosely within the chamber from its-upper
end, the said dome being arranged to raise with the accumulation of heated-air
therein. P indicates a strip of wire bent right angularly at both ends. to form
the arms. The end of the arm is bent as seen, to engage in a small
aperture at the top of the dome ; and the end of the arm is formed into a
yoke which straddles the sleeve-B beneath the flange b. By this arrangement,
as the dome rises by the accumulation of hot air within the vessel, the yoke. is
caused to move upwardly the sleeve B, thus diminishing the flame of the lamp and
reducing the temperature. By this means vaporization is prevented, and a uniform
degree of temperature is maintained for any length of time..
indicates a band which is placed-around the legs e in a plane with the flame of
the lamp, thereby protecting said flame but permitting the access of air thereto.both
below and above said band.
--In the operation of my invention I first remove the dome.0.and then pour water
into the chamber 6, not permitting the water to enter the tube H. The water
passes through outlet J and hence through the tubing,, traversing the entire coil,
and returning, passes from the other end of the tubing through nozzle Kand into
the chamber The water within chamber Frises to approximately. the point
indicated by the dotted line, when the air outlet is shut off by, the closure of the
lower end of tube H. The lamp should now be ignited, when the heat from the
flame will expand the air in chamber F, and thus force the water.in said chainber
through tube H into chamber G, whereby the pressure is relieved, in chamber E
and a partial vacuum created, causing a fresh quota of air to enter chamber F
through inlet K. This at once starts the circulation of hot water, which is main-
tained so long as heat is applied against chamber F. As before explained if the
heat should be too intense so as to create an excessive pressure, the dome. O will

page_text: be raised thereby, and the upward movement of the dome communicated through
rod P and yoke p³ to flange b and sleeve B, will raise the latter and thus diminish
the flame.
Although I have described the special construction which I prefer to use in
forming my said apparatus I am aware that said construction may be modified in
various details without departing from the spirit of my invention and I do not
wish to be limited by such special construction.
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:-
'
1. A device for creating and conveying a continuous circulation of heated wate
for application to the body through a hollow flexible tube, substantially as set
forth.
2. A double chambered water containing vessel having respectively an outlet
and an inlet, a coil of tubing connected with said outlet and inlet, and means
whereby the application of heat to one chamber causes circulation of water through
said coil and said chamber, substantially as set forth.
3. A hot water appliance consisting of a double chambered water containing
vessel, having an air space between said chambers, an outlet for one of said
chambers and an inlet for the other of said chambers, said outlet and inlet com-
municating through a suitable medium, and a direct tubular connection between.
the said chambers, whereby water heated primarily in one of said chambers, is set
in circulation, substantially as set forth.
4. In a hot water appliance consisting of a double chambered vessel and a coil
of tubing connecting said chambers for the circulation of water, a lamp to heat one
of said chambers, a burner tube upon said lamp and a sleeve surrounding said
burner tube, with means whereby said sleeve may be raised to diminish the flame
issuing from the burner tube, substantially as set forth.
5. A lamp having a burner tube and a wick sheath placed therein, an outer
sheath enclosing the burner tube and having a radial flange, a pivoted piece
ranged to be moved against said flange to raise the said outer sheath, and a
friction piece in juxtaposition to said pivotal piece to hold it in a desired position,
substantially as set forth.
6. In a hot water appliance consisting of two water containing chambers having
a tubular connection, a burner tube arranged to direct a flame against one of said
chambers, and a slidable sleeve around said burner tube; a telescoping dome in the
other of said chambers, and a wire connecting said dome and slidable sleeve, whereby
the upward movement of said dome, due to the heat expansion in its chamber, is
communicated to the slidable sleeve, causing it to diminish the flame of the burner,
substantially as set forth.
7. In a hotwater appliance, a coil of flexible tubing arranged and secured upon a
sheet of flexible material, the opposite ends of said coil communicating with
separate water chambers, substantially as set forth.
8. In a hot water appliance, two water chambers having respectively an outlet
nozzle and an inlet nozzle, a short length of tubing connecting with each of said
