I, JAMES HENRY MITCHELL, of Chestnut Hill, Philadelphia County, State
of Pennsylvania, U.S.A., 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:-
The object of my invention is to provide a machine for delivering a continuous
sheet, or series of sheets of dough, each completely enclosing a filling of fruit, or
the equivalent, the sheet being of such a character as to be conveyed to any cutting
mechanism for division into portions ready for baking. This invention involves
certain novel and useful combinations or arrangements of parts, and peculiarities of
construction and operation, all of which will be hereinafter first fully described, and
then pointed out in the claims.
In the accompanying drawings,
Fig. 1 is a plan view of my improved fruit biscuit machine.
Fig. 2 is a vertical sectional view at line a-r of Fig. 1.
Fig. 3 is a bottom plan view of the delivery plate and nozzles.
Similar numerals of reference, wherever they occur, indicate corresponding parts
in all the figures.
7 is a
1 is a hopper, mounted upon a main frame 2. Within this hopper, and forming
the bottom thereof, are rotably mounted upon shafts 3, grooved or serrated rollers, 4.
5 are gear wheels secured upon the shafts 3, the teeth of said wheels meshing, as
illustrated in Fig. 1. 6 is a driving pulley mounted upon one of the shafts 3.
dividing device, adjustably fixed in the hopper, 1, and having its bottom curved, as
particularly shown at 8, (Fig. 2). The radius of this curve is greater than that of
the peripheries of the rollers 4, and thus a gradually narrowing throat or passage
way is formed between the division and the rollers. The hopper 1 is divided into
two compartments, 9 and 10, compartment 9 being designed to hold dough, and
compartment 10 fruit. 11 is a vertically adjustable gate whereby the quantity of
fruit supplied may be regulated at will.
12 is a division plate extending from the device 7, into a slot in a fixed division
plate 13, mounted in the compressing chamber, forming it into two compart-
ments, 14 and 15. 16 are fixed scraping knives, which bear against the peripheries
of the rollers 4 for removing the dough and fruit, and preventing the same being
carried around by said rollers. The bottom 17, of the compressing chamber 14, is
perforated with a number of escape openings 18, formed in a plate 19 secured
thereto. Compressing chamber 15 is provided at bottom with a number of
nozzles, 20, corresponding in number and shape to the dough escape openings. For
convenience in illustration, I have shown a carrying belt 21 mounted beneath the
machine, for receiving the sheet of dough and fruit.
In operating the machine, dough is placed in hopper 9, and fruit in hopper 10.
When the rolls are started, in the direction of arrow the dough is forced through
the passage between the roll and plates 8 and 12, and as this passage is gradually
restricted, the dough is forced and compressed into the chamber 14, filling all the
space around the nozzles 20, and escaping through the plate 19 in hollow flattened
strips. Fruit having been placed in the hopper 10, is acted upon precisely like the
dough, and is compressed into the chamber 15, escaping through the nozzles 2!), but
it is entirely surrounded by the dough. The strips are deposited upon the carrier 21
and cut to proper lengths for baking.

page_text: Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
1. In a fruit biscuit machine, a dough hopper, a fruit hopper, two forcing rolls,
a dough compressing chamber having a series of openings through its bottom, and
a fruit compressing chamber provided with nozzles projecting into the dough exits,
substantially as shown and described.
2. In a machine of the character herein specified, a dough compressing chamber
provided with elongated dough outlets, in combination with a fruit compressing
chamber having outlet nozzles entering the dough outlets, as set forth.
3. In a machine of the character herein specified, a serrated or fluted compressing
roll, in combination with a converging plate located at one side of the roll, as
set forth.
4. The combination with a compressing roll of the character herein shown, of a
stationary scraping knife, arranged as set forth.
5. In a machine of the character herein specified, a fruit discharge nozzle, in
combination with mechanism whereby a covering of dough is applied to the fruit,
substantially as shown and described.
