PROVISIONAL SPECIFICATION.
Improved Apparatus for Heating Water.
I, JOHN PITT BAYLY, of 18 Fulham Place, Paddington, in the County of
London, Patent Agent, do hereby declare the nature of this invention (a
communication to me from abroad by John Brandt, of Terre Haute, Indiana,
U.S.A., Inventor,) to be as follows:-
This invention relates to an improved apparatus for heating water, and is
specially applicable for use in connection with wash-boilers, wash-tubs, barrels,
boxes, bath-tubs, and the like where it is required to quickly heat the water
contained therein.
By this invention time, trouble, and money are saved, inasmuch as it is perfectly
clean, produces no smoke, and no unpleasant odour, and no heat is wasted.
The apparatus consists of a square box preferably constructed of galvanized
iron, or other noncorrodable material. Two-thirds of the box is perforated with
copper tubes which extend from side to side of the box, and which are connected
in such manner as to form several coils of pipe. At the lower portion of the box is
a hot-chamber in which is contained the fire, which is produced by gas-burners, or
gasoline-burners. The burners are directly under the copper tubes, and the flame
and heat ascends around them. In operation the box is sunk and held in the water
by a cast-iron bottom, and the water surrounding the box and within the tubes
becomes heated, passes out, admits the cold water, and thus keeps up a constant
water current.

COMPLETE SPECIFICATION.
Improved Apparatus for Heating Water.
I, JOHN PITT BAYLY, of 18 Fulham Place, Paddington, in the County of
London, Patent Agent, do hereby declare the nature of this invention (a
communication to me from abroad by John Brandt, of Terre Haute, Indiana,
U.S.A. Inventor,) and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement :-
My invention relates to improvements in apparatus or devices for heating the
water contained in bath-tubs, church baptisteries, tanks, pools, and other
receptacles.
It has long been a serious question how to heat the water in reservoirs or vessels
similar to those above named and for similar purposes without the employment of
Many
the expensive hot-water connections and heaters now in common use.
attempts have been made to provide a heating device for use in the connection
above set forth; but owing to defects in their construction or mode of operation,
or owing to the great expense or cost of manufacture or their unreliability to
perform the object sought to be attained, they have proved more or less abortive
and have not been introduced into general public use.
My invention is designed to obviate the above and other objections, and provide
a heater for bath-tubs, church baptisteries, and other similar places, which shall be
simple in construction, economical in manufacture, and durable in use, and by

page_text: which water can be heated expeditiously and rapidly and at a very small cost for
the fuel consumed.
The invention consists in the several novel features of construction and new
combinations of parts hereinafter fully described, and definitely pointed out in the
appended claim.
In the accompanying drawings, in which similar figures of reference indicate like
parts in all the views, Figure 1 is a side elevation of an apparatus constructed
according to my invention. Fig. 2 is a central longitudinal section of the same.
In the said drawings the heating device is represented as being composed of an
L-shaped vessel and a flue having a width equal to the width of the heater,
whereby it presents an extensive heating-surface to the water, said flue leading
upward from the horizontal portion of the heater. The base portion 1 of this
vessel constitutes the chamber for the burner or heater 2, consisting of an
oil-reservoir 3, an oil-pipe 4, bent at right angles at its lower end, forming a
horizontal burner-tube 5, in which is inserted one or more burners 6. The vertical
portion 7 of the vessel forms the cold-air flue, and is provided with a sliding cover 8,
provided with perforations 9, for the entrance of air, and with a slot 10 in its inner
edge for the passage of the oil-tube 4.
The numeral 12 designates a slide which serves to close communication between
portions 1 and 7, except at the bottom, where there is a small opening 13, which
serves as an entrance for the cold air for supporting combustion and also for the
passage of the oil-tube. This slide is provided with a lug 14, by which it may be
operated. The numeral 15 designates the hot-air or heating flue. It is made to
take a winding, zigzag, or tortuous course, as shown, so as to present a large heating-
surface. This flue is open at its upper end, which is on or about on a level with
the top of the vertical portion 7 of the vessel, and communicates at its lower end
with the top of the horizontal portion 1 containing the burners.
16, 16, designate vertical bars provided with a series of perforations 17. These
bars are firmly secured to the apparatus and serve to retain the same in place by
the holes engaging with nails, bolts, or other fastening devices on the sides of the
tub, tank, or other receptacle.
The device may be of galvanized iron or other suitable material, and should be
of such a height as to extend a short distance above the surface of the water.
The operation of the invention is as follows: The apparatus is placed in the
tub, tank, or other receptacle and secured thereto by means of the perforated bars,
being wholly submerged in the water except at the tops of the hot and cold air flues.
The burners are then lighted and in the horizontal portion 1 through the vertical
portion 7, and the slide is then lowered and the cover closed. It will be seen that
the air passage in the slide is at the lower portion thereof, so that the cold air from
the vertical portion will enter portion or chamber 1 through said opening, and
becoming heated will escape into the winding hot-air flue in the top of said vessel,
and thence pass through said flue to the outer air. By the above construction the
water will be thoroughly and rapidly heated by the heat radiated from the heating-
vessel.
Instead of the oil-reservoir, oil-pipe, and oil-burners being employed, it is obvious
that a gas pipe and burners, connected with a service or other pipe, may be
employed without departure from my invention.
The horizontal portion 1 is provided with a number of transverse tubes 18,
located above the burners, and through which the water in the tank may
circulate.
Having now particularly described and ascertained the nature of this my said
invention, and in what manner the same is to be performed, I declare that
what I claim is :
A heating apparatus consisting of the vessel having the horizontal and vertical
portions, a slide located between said portions and provided with an air-passage in

page_text: its lower end, a zigzag hot-air flue having a width equal to the width of the vessel
and extending upward from the horizontal portion thereof, whereby it presents an
extended heating surface to the water, transverse tubes extending across said
horizontal portion, and a burner or burners located in position beneath the zigzag
flue, substantially as described.
