Confectioner do hereby declare the nature of my said invention for "IMPROVEMENTS
IN OR CONNECTED WITH BAKERS' OVENS FOR THE PURPOSE OF PROVIDING A
SUPPLY OF HOT WATER" to be as follows:-
In bake-houses hot or warm water is required for use in the process of mixing
and preparing the dough, and also for the purpose of cleaning and scalding the
utensils used during the process, and the object of this invention is to provide or
combine with the oven, an apparatus of simple construction which will ensure a
constant supply of hot water.
The invention consists in placing in the oven, a pipe or pipes coiled or otherwise
arranged, and connecting the same with a cistern or tank, the water circulating
from the tank through the pipe, and back again into the tank.
If
In carrying out the invention a pipe or tube, preferably of wrought iron, is placed
in the oven at or near the side, preferably in the form of an elongated U, in which
position it occupies but little space if placed against the side. wall of the oven.
it is desired to get more heating surface, the pipe may be made in coils or placed
in zig-zag position against the side wall or round the end, but the first mentioned
arrangement will probably be found sufficient. In front of or at the side of the
oven, is placed a tank or cistern (one such as is at present used for the supply of
hot water from a kitchen boiler would answer the purpose), and to this tank are
connected the ends of the pipe, so as to cause the water to circulate from the tank
through the pipe and back again. Instead of one pipe two or more may be
employed if found more convenient, and two or more cisterns may also be used,
say one at each side of the oven, where it is found that one is insufficient. The
tank may be provided with a tap, from which the water may be withdrawn and a
supply tap either self regulating or otherwise as desired.

page_text: I, DAVID SAWYER, of 3 Chapel Street, Southport, in the County of Lancaster
Confectioner do hereby declare the nature of my said invention for IMPROVEMENTS
IN OR CONNECTED WITH BAKERS' OVENS FOR THE PURPOSE OF PROVIDING A
SUPPLY OF HOT WATER, and in what manner the same is to be performed, to
be particularly described and ascertained in and by the following statement:—
In bakehouses hot or warm water is required for use in the process of mixing
and preparing the the dough and also for the purpose of cleaning and scalding the
utensils used during the process, and the object of this invention is to provide or
combine with the oven an apparatus of simple construction which will ensure a
constant supply of hot water.
The invention consists in placing in the oven or building in the inner walls of it
a pipe or pipes coiled or otherwise arranged and connecting the same with a cistern
or tank, the water circulating from the tank through the pipe and back again into
the tank.
It will be best described by aid of the accompanying drawings in which
Figure 1 is a front elevation of baker's oven shewing the invention, and
Figure 2 sectional elevation of same on line x-y.
The oven A is made of ordinary construction built in with brickwork B and
provided with doors C. In the oven A, I place a pipe or tube D of wrought iron
or other metal at or near one side and preferably in the form of an elongated U in
which position it occupies but little space if placed against the side wall of the oven.
If it is desired to obtain more heating surface, the pipe may be made in coils or
placed in zig zag position against the side wall or round the end, but the arrange-
ment shewn will probably be found sufficient. A tank or cistern G (one such as is
at present used for the supply of hot water from a kitchen boiler would answer the
purpose), is placed in front of or at the side of the oven or might be built into the
oven so as to expose a certain part of such tank or cistern to the internal heat of
the oven, and to this tank are connected the ends of the pipe, so as to cause the
water to circulate from the tank through the pipo, and back again. Instead of one
pipe, two or more may be employed if found more convenient, and two or more
cisterns may also be used, say one at each side of the oven where it is found that
one is insufficient. E is a ball tap to regulate the supply of water to the cistern,
and F a tap of any ordinary construction through which the water may be with-
drawn for use. The cistern or tank may be covered with covering of asbestos or
other non conducting material to prevent radiation of heat.
Having now particularly described and ascertained the nature of the said
invention, and in what manner the same is to be performed, I wish it to be
understood that I am well aware that circulating cisterns have been used for

page_text: storing heated water for domestic and other purposes and that broadly I make no
claim for such, nor do I claim any particular part of the apparatus shown in the
drawing, when taken separately and by itself, but I declare that what I claim is
The manufacture for and use with a baker's oven of a pipe or pipes placed inside
the oven in U or zig zag form or in coils or otherwise in combination with and
connected to hot water cistern for the purpose of providing a supply of hot water
substantially as described.
