I HENRY MAINWARING of Mouncey Street Charles Street, Chorton-upon-
Medlock Manchester, in the County of Lancaster, England, Brass Founder, Brass
Finisher and Coppersmith, do hereby declare the nature of my said invention for
IMPROVEMENTS IN HOT WATER CIRCULATING CYLINDERS AND COLD WATER TANKS
FOR SUPPLYING HOT AND COLD WATER TO BATHS, to be as follows :-
The object of this invention is the construction of a hot water circulating
cylinder and cold water tank combined, which shall be cheap to manufacture,
occupy little space and be easily fixed in position.
In carring out my invention I construct a vertical cylinder of sheet copper, tin,
or iron or of cast iron or any other suitable material, but by preference, of sheet
copper tinned to avoid corosion.-I devide such cylinder-into three compartments
by partitions of the same material as the, body.-The centre compartment being
made open to the atmosphere by perforations surrounding the same to avoid
radiations or the uper and lower compartments may be made seperately with
sockets projecting beyond the bottom of the upper compartment thus enabling one
to slip in the other and so forming the centre compartment.
The upper compartment of the cylinder is used as the cold water tank and is
provided withe the ordinary ball inlet valve for the automactic supply of the cold
water; and also with an overflow pipe in case of such ball tap getting out
of order.
.
The lower compartment is used as the hot water circulating cylinder and is
provided with suitable inlet and outlet pipes communicating with the kitchen.
boiler or other independent boiler as may be most convenient. From the top of
this hot water circulating cylinder I take the delivery pipe for supplying hot water
to any part of the building as desired; a branch of such delivery pipe being
continued to the atmosphere and such branch might be turned down to the cold
water tank. I also provide a cock to the bottom of this compartment for the
purpose of emptying the same for cleansing.

serves to supply the lower compartment or hot water cylinder with a fresh supply
of cold water as the hot water may be used. A stop cock being provided in such
pipe to close the communication if desired.
•
A water guage may be provied to the hot water circulating cylinder to indicate
the height of water in the cylinder in case of frost or accident to any part of the
feed pipe.
.
It will be obvious that the hot water compartment can only be emptied by the
draw off cock or by evaporation.

I HENRY MAINWARING of Mounsey Street Charles St Manchester in the County
of Lancaster Coppersmith, Brass Founder do hereby declare the nature of my said
invention for IMPROVEMENTS IN HOT WATER CIRCULATING CYLINDERS AND COLD
WATER TANKS FOR SUPPLYING HOT AND COLD WATER TO BATHS and in what
manner the same is to be performed, to be particularly described and ascertained
in and by the following statement :-
The object of this invention is the construction of a Hot Water Cylinder
(circulating) and Cold Water Tank combined, which shall be cheaper to manu-
facture shall occupy less space, and be more easily fixed in position, than has
hitherto been practicible And in order that this my said invention may be the
more readily understood and carried into practical effect, I have hereunto annexed
a sheet of drawings illustrative of my improvements, and will now proceed to
describe the same with the assistance of the figures and letters of reference marked
thereon Figure 1 is a side sectional view of a Hot Water Circulating Cylinder B
and Cold Water Tank A constructed separately and Fig. 2 is a side view of a Hot
Water Circulating Cylinder and Cold Water Tank constructed altogether, in
accordance with this invention where the same letters of reference are used they
indicate like parts in both views, In carrying out my invention I construct a
vertical Cylinder of Sheet Copper, Tin or Iron or of Cast Iron or any other suitable
material but by preference of Sheet Copper tinn'd to avoid corrosion, and divido
such Cylinder into three compartments by partitions A and B of the same material
as the body, the centre compartment C being made open to the atmosphere by
perforations D surrounding the same to prevent conduction or the upper com-
partment A and the lower compartment B may be constructed separately with
a socket (C) as seen in Fig. 1.) projecting beyond the bottom of the upper
compartment A and a socket (D) projecting beyond the top of the lower com-
partment B thus enabling one to slip into the other, and so forming the third or
centre compartment (C).
The upper compartment of this Cylinder is used as the cold water tank, and is
provided with the ordinary ball inlet valve E for the automatic supply of cold
water and also with an overflow pipe F in case of such Ball Valve getting out of
order, The lower compartment B is used as the Hot Water Circulating Cylinder
and is provided with suitable inlet pipe G and outlet pipe H, communicating with
the Kitchen Boiler or other independant Boiler as may be most convenient, from
near the top of this Hot Water Circulating Cylinder B, I take the delivery pipe I
for supplying Hot Water to any part of the building desired, a branch J of such
delivery pipe being. continued to the atmosphere and such brauch J might be
turned down to the Cold Water Tank A. I sometimes provide a cock K near the
bottom of compartment B for the purpose of emptying the same for cleansing.
I arrange a pipe L' communicating with the upper compartment A and lower
compartment B, which serves to supply the lower compartment, or Hot Water

page_text: Circulating Cylinder B with a fresh supply of cold water as the Hot Water may
be drawn off.
A stop cock M may be provided in such pipe to close the communication if so
desired I sometimes form a branch N in the pipe L for drawing cold water from
the tank A O is a base plate upon which the whole may be mounted. A Water
Guage may be provided to the Hot Water Circulating Cylinder B, to indicate the
height of water in the Cylinder, this is useful in case of frost or accident to any
part of the feed pipe. It will be obvious that the Hot Water Circulating
Cylinder B can only be emptied entirely through the cock K or by evaporation,
this proves a safeguard against accidents, as in case water cannot be drawn off by
the ordinary taps, it will be an indication that the apparatus is out of order P is a
rail which might be used for the purpose of drying Clothes or Towels.
Having thus particularly described; and ascertained the nature of this, my said
invention, together with the best methods with which I am acquainted for carrying
the same into practical effect I wish it to be understood, that I do not confine
myself to the precise details relative proportions and dimensions of the apparatus
hereinbefore described and illustrated on the accompanying drawing as the same
'may be considerably varied. without departing from the invention, but what
I claim and desire to secure by Letters Patent is the construction and arrangement
of a Hot Water Circulating Cylinder and Cold Water Tank one above the other,
with a central space open to the atmosphere as and for the purposes herein before
described and illustrated on the accompanying drawing.
