IMPROVEMENTS IN DAMPING BISCUITS AND IN APPARATUS OR APPLIANCES THEREFOR
Year: 1884

page_text: PROVISIONAL SPECIFICATION,
We THOMAS VICARS the Elder, JOHN VICARS the Elder, THOMAS VICARS the
Younger and JOHN VICARS the Younger all of 29 Seel Street, Liverpool, in the
county of Lancaster Engineers, do hereby declare the nature of our said invention
for IMPROVEMENTS IN DAMPING BISCUITS AND IN APPARATUS OR APPLIANCES
THEREFOR to be as follows:-
As is well known in the trade certain biscuits such as ginger nuts after they have
been moulded require to be damped before they are baked. Hitherto the damping
has been mainly effected by hand has been irregular and has occupied considerable
time: damping by ineans of automatically acting apparatus or appliances has not
hitherto been practised to any great extent in consequence of the difficulty
experienced in obtaining a spray sufficiently fine to spread evenly and regularly and
to damp the whole of the biscuits uniformly and just as much as was requisite.
Now the objects of our invention are to damp biscuits with regularity and
uniformity. exactly in the proportion and to the extent required and to provide
suitable apparatus or appliances for carrying the said damping into effect.
Our invention consists. First: In damping biscuits by means of jets of water
broken into spray and allowed to descend in a finely divided condition like mist on
the biscuits to be damped.
Second. In obtaining the finely divided mist like spray by means of a series of
jets connected to a suitable water supply and so arranged as to direct thin streams
of water at a high velocity in an upward direction against a baffle plate or plates
placed at such an angle as to receive the impact of the water in an oblique direction
and direct the said water forward and upward in the form of spray to finally fall
by the action of gravity on the biscuits to be damped.
Third. In ensuring that the biscuits shall be damped to the required degree only
by moving them through the mist-like spray on trays carried forward at any
desired rate of speed by means of travelling bands or chains or equivalent devices
such as a rotating table.

DESCRIPTION OF THE DRAWINGS.
--
In the accompanying sheet of drawings, fig 1, is a. side elevation, fig 2 a vertical
section, and fig 3 a plan of apparatus or appliances constructed for damping biscuits
in accordance with our invention. a frame preferably of cast iron, b water supply
pipe, c stop valve; d jet nozzles in the supply pipe be baffle plate, f trough to catch
any water escaping from d and not properly directed or divided into mist like spray,
g endless chains travelling around the wheels hh, i driving wheel, j tray of biscuits
carried by the chain g. k trough in which moisture not deposited on the biscuits is
collected.

page_text: Trays containing the biscuits to be damped are placed on the chains at h and
travel slowly in the direction of the arrow to h¹ passing on their way through the
mist like spray and becoming thereby damped to the required degree. When the
trays arrive at h¹ they are removed to the oven.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that what
we claim is
First. Damping biscuits by means of jets of water broken into spray and allowed
to descend in a finely divided condition on the biscuits to be damped substantially
as setforth.
Second. The combination in biscuit damping apparatus or appliances of a series
of jets and a baffle plate disposed and arranged substantially in the manner and for
the purposes setforth.
Third. In biscuit damping apparatus or appliances constructed under our
invention endless carrying bands or their equivalents for the purpose 'setforth.
