This Invention relates to a new or improved machine or apparatus for interposing
or spreading layers of jam or fruit on or between layers of dough, cake, or biscuit,
and consists of a moving endless belt or apron and a pair of rollers. These rollers,
which may be worked in any convenient manner, roll out the fruit and the cake
or dough into a thin sheet onto the endless belt. A box having a long narrow
opening at the bottom contains the jam or fruit, and is provided with a piston to
force out the jam or fruit through the said opening in a thin layer or sheet onto
the first layer of cake or dough. The apparatus has also a second pair of rollers
which roll out a second layer of cake or dough and deposit it on the layer of jam
or fruit. A long strip or sheet is thus formed composed of a layer of jam or fruit
interposed or placed between two thin layers of cake or dough. Any suitable
means may be provided for cutting the long strip or sheet into convenient lengths
or shapes.
A single pair of rollers, in combination with an endless apron and a jam or
fruit box, may also be used when it is desired to obtain a single sheet or layer of
cake o dough with a layer of jam or fruit.

an Order of the Lord Chancellor, filed by the said George Charles Bacon in
the Great Seal Patent Office on the 16th February 1881.
GEORGE CHARLES BACON, Clerk to John Clayton Mewburn, of 169, Fleet Street,
in the City of London, Patent Agent and Consulting Engineer. "A NEW OR
IMPROVED MACHINE OR APPARATUS FOR INTERPOSING OR SPREADING LAYERS
OF JAM OR FRUIT ON OR BETWEEN LAYERS OF DOUGH, CAKE, OR BISCUIT."
(A communication from abroad by Walter Scott Ovens, of Buffalo, New York, in
the United States of America.)
The object of this Invention is to provide a cheap and rapid means for inter-
posing a layer of fruit or jam between two layers of other material forming the
cake or biscuit; and it consists of an endless belt or apron provided with the
usual means for giving it its proper movements, a pair of rollers adapted for rolling
out a thin sheet of the first layer of cake material, and depositing it upon the said
belt or apron in combination with a fruit box, provided with a long narrow opening
at the bottom and a piston or plunger for forcing the fruit out in a thin layer upon
the first layer of cake material, which is carried along under it by the endless belt
or apron, and a second pair of rollers adapted for rolling out a second layer of cake
material and depositing it upon the layer of fruit, which is carried by the endless
apron forward as fast as it comes from the rollers, thereby producing a sheet of
fruit cake material composed of three layers, first, a layer of fruit cake material;
second, a layer of fruit or jam; third, a layer of cake or biscuit material. The three
layers after being thus united may if required be passed through an ordinary
biscuit machine, and cut up into cakes or biscuits of various sizes or shapes, or made
into rolls, as will be more clearly hereinafter shown by reference to the Drawings,
in which,
Figure 1 is an enlarged portion partly in section of the machine showing the
manner of connecting the screw for the fruit box, piston, or plunger, to the shaft
which operates it; Figure 2 is a side elevation of the machine complete; Figure 3
an enlarged view partly in section of the piston or plunger showing the screw and
a diagram of the bevel gearing by which it is operated, also a cross section through
a portion of the fruit box, the whole showing the position of the plunger when
swung out of the way so as to leave an opening to put in the fruit or clean out the
box; Figure 4 is a plan view of the machine; Figure 5, a cross section through the
fruit box and plunger, and Figure 6 represents an enlarged vertical section through
a portion of the product of the machine.
A represents the frame of the machine. It is made preferably of cast iron as
being the cheapest and strongest material, and is held together by the usual
binding rods A¹; A² is the endless apron arranged in the usual way on rollers B, B¹.
It receives its proper movements by means of the pulley C, belt C₁, and pulley Ca
on the driving shaft D, the upper side moving in the direction of the arrows.
the frame A is bolted in the usual way the vertical frames D¹, between which the
fruit box D2 is securely fastened by bolts E about five or six inches above the
endless apron.
Το
E' is the plunger, to which is attached a hollow column E2 either cast in one
piece with it, as shown in Figure 3, or bolted to it by bolts F, as shown in Figure 5.
Through the top of the column E2 the screw rod F¹ passes, and is fitted so as to
screw in or out (see Figure 1), and is held up in a box F by means of a groove G
in its upper end (see Figure 1) and one or more set screws G¹. The said box Fis
made in two parts f, f, as shown in Figure 1, and is held securely to the shaft G²
by means of one or more bolts g. It is fitted so that the shaft G can turn easily
within it. To the screw rod F¹ is rigidly fastened a bevel gear wheel H, and to
the shaft G³ is also connected a similar wheel H¹ which gears into H.

page_text: It will be seen that a movement of the shaft G2 will, through the gearing H, H',
cause the screw rod F¹ to turn, and thereby move the plunger E¹ up or down,
according to the direction in which it may be turned. When the plunger is at the
limit of its upward movement, and it is desired to either fill or clean the fruit box,
it is swung out so that it passes to the front of the box D2, the shaft G² acting as
a support upon which it swings (see Figure 3).
The first pair of rollers are represented by the letters h, h'. They are geared
together in the usual way by gear wheels e, el, (shown in Figure 4).
represents an inclined platform, upon which the dough is placed to be fed
between the rollers.
1, 2, is the second
pair of rollers, and J' the inclined platform upon which the
dough is placed to be fed into them. They are also geared together by gear
wheels e, e³, (shown in Figure 4).
The upper roller is provided with a wide face pulley N, which pulley is con-
nected by a belt N' to the pulley N2 on the shaft G2, which when in motion
imparts the necessary rotary movement to the rollers, . The rollers h, h', receive
a similar motion from the pulley N (the face of which is wide enough for two belts)
and the belt O and a pulley O¹ on the shaft or roller ².
The bevil wheel H₁ is arranged to turn loosely on the shaft Gs when not engaged
with the clutch Q (shown in Figure 4). It is made in the usual way, and is kept
from turning on the shaft G2 by a feather. P represents the handle by which it
is operated. The object of the clutch is to provide the means for either starting
or stopping the fruit box plunger, and thereby controlling its operation without
interfering with the operation of the rest of the machinery.
At the bottom of the fruit box D2 is a long narrow opening V arranged lengthwise
of the box, which opening is made adjustable in width or may be closed when it
is necessary by means of the plate I, which is held to the bottom of the box D by
screws or bolts ¹ so as to allow it to be moved to or from the plate I by means of
one or more screws R.
H in Figure 2 represents one of the ordinary thumb nuts for tightening the
endless apron.
The operation of the Invention is as follows:-The dough placed on the plat-
form J is formed into a sheet (shown by dotted lines in Figure 2) as it passes
through the rollers h, h¹, and is carried along under the fruit box.
The jam or
fruit prepared in the usual way so as to form a paste of sufficient firmness, being
placed in the box D2, is now started by means of the clutch heretofore mentioned,
which causes the gearing H', H, to force the plunger E' down into the box, and
force out a thin sheet of the fruit (shown by dotted lines x', Figure 2) down on
the sheet of dough x, and as the apron carries the two sheets x, x', along they pass
under the rollers L, A, when another sheet of dough (see dotted lines ² in Figure 2)
is laid upon the fruit, thereby completing the fruit cake material as before men-
tioned, the movements of all parts of the machine being so timed that the three
sheets are laid evenly and smoothly together.
The completed fruit sheet may be rolled up into an ordinary 'rolled cake, or it
may be passed through a common biscuit machine through the rollers H³ and c
(shown in Figure 2) and through the machine so as to be cut in the ordinary way
into fruit cakes or biscuits.
Instead of belts for moving the rollers the well known gear wheels may be used
to effect the same purpose.
As a modification of the Invention I would state that a pair of rollers arranged
similar to h, h, and a platform or feed box may be substituted for the fruit box D
and used in its place when the fruit or other compound is made into paste thick
enough to be passed through rollers, which rollers should move so as to roll the
sheet of dough out as fast as the endless apron moves.
In some cases the two pairs of rollers h, h, and 1, 1, may be used without the
fruit box D, for instance, when it is desired to make cakes consisting of two sheets
of dough of different colors, or in one of which finely cut fruit has been mixed, in

page_text: which case the product of the machine would consist of two layers instead of three,
and when it is intended to make jelly cake to be rolled into rolls only the first
set of rollers h, h, and the fruit box D2 would be used.
Having now described the nature of the said Invention as communicated to
me, and in what manner the same is to be performed, I declare that I claim,-
First. The rollers h, h³, having a suitable platform or feed box to receive the
dough, and the means, substantially as described, for giving them the necessary
motion, a jam or fruit box D2 provided with an opening V through the bottom,
a plunger E and its accompanying mechanism for operating it, in combination
with a second pair of rollers 7, 1, a platform J', and an endless apron A², the whole
combined for joint operation, whereby three sheets of cake material are made and
smoothly laid together, substantially as specified.
Second. The two pairs of rollers h, h, and 1, 1, each provided with a suitable
platform or feeding box J or J', in combination with an endless belt or apron A²,
and a suitable means, substantially as specified, for giving each their proper move-
ments, whereby two sheets of cake material are made and laid together, substantially
as described.
Third. The combination of the rollers h, ', and the endless apron A³ with the
fruit or jam box D2 and their operating mechanism, substantially as specified, for
producing a single sheet of biscuit or cake material covered with a thin layer of
fruit or jam as described.
In witness whereof, I, the said George Charles Bacon, have hereunto set
my hand and seal, this Sixteenth day of February, One thousand eight
hundred and eighty one.
