page_text: PROVISIONAL SPECIFICATION left by Richard Archibald Brooman at
the Office of the Commissioners of Patents, with his Petition, on
the 14th December 1863.-A communication from abroad by Auguste
Cardinal, junior, of Nantes, France.
I, RICHARD ARCHIBALD BROOMAN, of 166, Fleet Street, in the City of
London, Patent Agent, do hereby declare the nature of the said Invention
for "IMPROVEMENTS IN SHIPS' COOKING AND DISTILLING APPARATUS," to be as
follows:-
This Invention consists in constructing apparatus for cooking, and at the
same time distilling salt water and obtaining fresh water therefrom, entirely of
iron, in manner shewn in the accompanying Drawings.
Figure 1 is a front view of the apparatus; Figure 2, a vertical section
through the line C, D, of Figure 5; Figure 3, a horizontal section through
the line E, F, of Figure 2; Figure, a horizontal section through the line
C, K, of Figure 5; Figure 5, a vertical section through the line A, B, of
Figure 1; and Figure 6, a plan.
a is the fire-place; b, supports for the grate bars b'; c, ash-pit; d, bridge to
support the grate bars and prevent the fuel falling behind the grate; e, par-
tition to cause the hot gases to circulate round the oven, and enter the
rectangular case under the boilers; f, damper; 9, reservoir or rectangular
case pierced with small holes to allow the steam to enter the double reser-
This reservoir is preserved from contact with the flame by water,
which is independent of the water level over the fire, and serves by means of
the cock to feed the boiler p when it has been heated.

page_text: This cock is fitted to the cooking apparatus, and takes water for feeding
the boiler from the upper part of the refrigerator or condenser. As this
water is at an elevated temperature the ordinary cases may be dispensed with.
The rectangular case g, in which the pans and other cooking vessels are
placed, is kept from contact with the flame by the water over the fire-place; a
second partition y is placed in the case g, forming two compartments g, g¹;
the compartment 9 serves for the cooking utensils; an outlet formed in front
of the partition allows the hot gases to pass into the compartment g to heat a
second oven placed over the fire. Above this oven there are small pans,
which are also heated before the gases pass into the chimney G, which for
convenience is placed at the back. k, k, are gauges indicating the water
level in the boiler p; l, pipes taking steam from the boiler p, they are covered
by the reservoir m, which is furnished at its lower part with an emptying
cock, and at its upper part with a pipe 9 which conveys the steam to a refri-
gerator or condenser; o is an outlet cock to the boiler p; r is an oven, the
sides of which extending nearly the whole depth of the apparatus, are kept
from contact with the fire by water. The arrows in Figures 3 and 4 indicate
the course taken by the products of combustion.
The sea or salt water is poured through the cock into the boiler p. The
fire being lighted, distillation as well as cooking commence; the product from
the distillation of the sea water from the boiler p rises through the tubes l
into the reservoir m, and from thence through the pipe q into a condenser
or refrigerator.
