PROVISIONAL SPECIFICATION.
Improvements in the Manufacture of Biscuits and Apparatus
therefor.
I, WILLIAM THEODORE CARR, of Carlisle, in the County of Cumberland,
Biscuit Manufacturer, do hereby declare the nature of this invention to be us
follows:-
This invention relates to the manufacture of biscuits by an improved method, and
by means of apparatus of special construction; the object of my invention being the
production of biscuits from two or more layers of dough of different kinds laid one
upon the other.
According to one mode of constructing machines for the manufacture of biscuits
according to my improved method, three (or more) pairs of rollers are arranged in
conjunction with guides and a travelling bed or carrier in such a manner that
whilst two (or more) of the sets of rollers respectively serve in the preparation of
the individual layers of dough whereof the biscuits are composed, the remaining
pair of rollers serves to reduce the compound sheet to the required thickness, its
component layers being at the same time caused to adhere together. Each layer of
dough as it leaves one of the pairs of preparing rollers is led to a travelling bed or
carrier, whereon the two (or more) layers of dough are received, one upon the
other, and whereby they are conveyed to the pair of finishing rollers.
The stratified sheet thus produced is ultimately cut or stamped in the usual
manner to form biscuits or cakes of any desired size or pattern.
Instead of rollers, "rout-presses," or other appliances known to those skilled in
the art to which my invention relates, may be employed in the production of the
several layers of dough and in their subsequent combination to form a stratified
sheet.

COMPLETE SPECIFICATION.
Improvements in the Manufacture of Biscuits and Apparatus
therefor.
I, WILLIAM THEODORE CARR, of Carlisle, in the County of Cumberland,
Biscuit Manufacturer, 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 :-
This invention relates to the manufacture of biscuits by an improved method, and
by means of apparatus of special construction; the object of my invention being
the production of biscuits from two or more layers of dough of different kinds laid
one upon the other.
In the accompanying drawings,
Fig. 1 represents in plan the left-hand part and Fig. 1B the right-hand part of
the special machine I employ for carrying out my improved method. The line of
division between these figures is indicated by the line, a.
Fig. 2 and Fig. 2B are corresponding views showing the machine in side
elevation; y, y being the line of division.
Fig. 3 is an elevation of the left-hand end of the machine.
Fig. 4 is an elevation of the right-hand end of the machine.

page_text: According to one mode of constructing machines for the manufacture of biscuits
by my improved method, four pairs of rollers A, B, C, D are arranged in conjunc-
tion with guides E, F, G and a travelling bed or carrier H in such a manner that
while the three first sets of rollers (A, B, C) respectively serve in the preparation
of the individual layers of dough whereof the biscuits are composed, the last or
remaining pair of rollers (D) serves to reduce the compound sheet to the required
thickness, its component layers being at the same time caused to adhere together.
The layer of dough leaving the pair of preparing rollers A is led by an endless
band K to the travelling bed or carrier H, the layer from the rollers B is laid by
the band L on the preceding layer, and the layer from the rollers C by the band M
on the two preceding layers; the three layers, one upon the other, being thereupon
conveyed by the bed or carrier H to the pair of finishing rollers D.
The stratified sheet thus produced is ultimately cut or stamped in the usual
manner to form biscuits or cakes of any desired size or pattern.
Although the machine illustrated in the accompanying drawings has four pairs
of rollers, there may be three or any other convenient number of pairs.
Instead of rollers, "rout presses or other appliances known to those skilled in
the art to which my invention relates, may be employed in the production of the
several layers of dough, and in their subsequent combination to form a stratified
sheet.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I claim :-
1. The improved method of manufacturing biscuits, substantially as herein
described, and consisting in feeding two or more layers of dough to a travelling bed
or carrier whereby they are conveyed to a pair of finishing rollers adapted to
compress the compound sheet to the required thickness, the stratified sheet thus
produced being ultimately cut or stamped to form biscuits of the desired size or
pattern.
2. In the manufacture of biscuits, the employment of two or more pairs of
preparing rollers, a pair of finishing rollers, and endless belts leading from the
preparing rollers to a travelling bed or carrier whereby the layers of dough are
conveyed one on the other to the finishing rollers, substantially as herein described,
the compound or stratified sheet ultimately issuing ready for being cut or stamped
into biscuits of the desired size or pattern.
3. In the manufacture of biscuits, the improved means arranged or operating
substantially as herein described and adapted to produce a compound or stratified
sheet of dough ready for being cut or stamped into biscuits of the desired size or
pattern.
