I, JOHN WHITTAKER, Junior, of 35 Peel Street, Sunderland in the County of
Durham, Fruit Merchant, do hereby declare the nature of this invention to be as
follows:-
My invention is an improved method of making jam by steam whereby regularity of
sweetening is easily and quickly accomplished. "My method also indicates when the
jam has been sufficiently cooked.
To effect my object, I place an ordinary steam pan such as is now used for boiling
jam on or in connection with the scale pan of an ordinary balance, or any other
weighing machine suitable for the purpose. By this arrangement the quantity of
sweetening material placed in the pan is at once made evident. As the loss of weight
consequent on the cooking of the jam is at once indicated, the cooking can be stopped
at the proper moment and thus regularity of cooking ensured.. The pan is attached to
the steam supply by a flexible tube.

To effect my object I place an ordinary steam pan such as is now used for boiling
Jam on or in connection with the scale pan of an ordinary balance, or any other
weighing machine adapted for the purpose. In operation the fruit is weighed and the
quantity of sweetening material required can be added with accuracy. As the
necessary loss of weight consequent on the complete cooking of the jam can be at once
indicated, the operation can be stopped at the proper moment, and thus regularity of
cooking is ensured.
To show more clearly how my invention is carried out I furnish a drawing.

and in what manner the same is to be performed, I declare that what I claim is :-
A method of making jam by steam by placing the pan containing the jam in con-
nection with a weighing maching during the process of boiling substantially as
described.
