Improved Cooling Machinery for Chocolate and the like.
THOMAS MAW 315 Victoria Park Road South Hackney London N.E. Confectioner
do hereby declare the nature of this invention to be as follows:-
My invention has for its object the application of cold compressed air for the
cooling of chocolate or other goods requiring quick cooling.
The machine consists of a strong air tight boiler or tank, fixed within another
tank of larger dimensions in the basement of the Factory. The larger tank is filled
with strong brine. The airtight boiler &c. is filled by air pump to about
80 lb. or 100 pressure. The said pump is fixed outside the larger tank. The air is
pumped through a coil of pipe that encircles the airtight boiler &c. (in the brine)
and enters the bottom of the airtight boiler &c.
The outlet for the compressed air is from the top of the airtight boiler &c. through
a coil of pipe that encircles the inside of the larger or brine tank.
For the making of Chocolate Tablets, Drops, &c. the cold air is taken through
pipes to the working tables, under which (tables) is fixed an air chamber, in the
centre of which is fixed small pipes to distribute the cold air under the tins of
chocolate in the form of an air spray. The said tins of chocolate are made to travel
on an endless chain to the end of the air chamber, from which they are (tins)
delivered to another endless band or chain & made to travel into the basement or
cold room, until cool enough to pack.

Improved Cooling Machinery for Chocolate and the like.
THOMAS MAW 315 Victoria Park Road South Hackney London N.E. in the County of
Middlesex Confectioner do 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 :-
My invention relates to a machine for cooling chocolate and the like by the action
of cold compressed air.
In order that my invention may be clearly understood, I have reference to the
accompanying sheet of drawings.

A is a tank or receiver for compressed air. B the larger tank filled with brine &

page_text: within which is placed the tank A. C pair of air pumps of ordinary construction used
for compressing and forcing air, and fixed in any suitable position. DDD compressed
air pipe & coil connected from pumps C to tank A passing around the inside of
the larger tank B. EE enclosed air chamber. F F Endless chains fitted with
brackets G G G the air chamber EE to be made any suitable height or horizontal
under the working table, H, the working table close to which is a door I in the side
of air chamber E. JJJ the outlet pipe from the tank A. KKKK taps connected
to the outlet pipe J, letting in the cold air to the air chamber E. L pressure gauge
fixed on the tank A. M handle connected with toothed wheel & pinion N.
O outlet door from air chamber E.
In working this machine first start the pumps C to keep a regular supply of air in
tank A from 60 to 80 lbs. pressure on gauge L, in working chocolate & the like, the
girl or girls stand at the table H filling the moulds with chocolate & the like and
then pass the full moulds into the air chamber E placing the full mould upon one of
the brackets G, and by giving the handle M part turn bringing the next bracket, in
position to receive the next mould, & so continue until the moulds arrive at the
bottom of the air chamber E near the outlet O when the moulds are taken out of the
air chamber E and stored in cool place ready for packing.
During the rotation of the endless chains & brackets F and G the first tap K is
opened to allow the cold air to circulate against the moulds in the air chamber E.
The other taps K K K to be opened as the moulds become lower in the air
chamber E.
I would have it to be understood that I do not bind myself to the exact details
or dispositions of parts as indicated in the drawings hereunto annexed, as this my
invention may be deviated from and differently disposed in detail without in the least
departing from the principle of my said invention.
Having now particularly described and ascertained the nature of my said invention
& in what manner the same is to be performed I declare that what I claim is:
First the passing of cold compressed air direct onto the moulds of chocolate and the
like in the form of a cold air spray S.
Second by the action of the said cold compressed air beingalways in a constant
motion, the warm air is driven direct out of the air chamber. By this means
chocolate & the like are kept in a cold condition.
Dated this 20th day of April 1897.
