COMPLETE SPECIFICATION.
Improvements in or relating to Cake and Cracker Making
Machines.
I, PEMBROKE DECATOR HARTON, of 100 Catherine Street, Philadelphia, in
the County of Philadelphia, and State of Pennsylvania, United States of America,
Gentleman, 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 invention relates to certain improvements in cake and cracker machines.
An object of the invention is to provide an improved machine for producing a
continuous ribbon composed of alternating layers of different materials, such as
dough and jelly or jam, and wherein the different materials are forced in to an
improved arrangement of separate chambers, and from thence through an improved
arrangement of concentric nozzles to form the sheet or ribbon of alternating layers
ready for the oven.
Another object of the invention is to provide certain improvements in details
of construction, and in arrangement of parts, whereby a highly efficient and
advantageous cake or cracker machine for producing sheets of alternating materials
is produced.
The invention consists in certain novel features of construction, and in the
combination and arrangements of parts as will be more fully described and pointed
out hereinafter.
In order that the invention may be better understood, attention is directed to the
accompanying drawings forming a part of this specification, and wherein :-

Figure 10, a longitudinal section thereof taken on the line 10-10 of Fig. 8;
and,
Figure 11, is a detail perspective of a cracker or cake formed or cut from the
sheet made by such machine as shown.
In all of the above views corresponding parts are designated by the same
numerals of reference.
The machine consists of a main frame having stanchions which are suitably
secured together, and at their extreme ends being provided with shafts. Each
shaft being suitably secured to the frame work of the machine. Each shaft
carries rollers over which an endless belt passes, which conveys the material fron
the hoppers.

page_text: The hoppers are secured to the frame near one end, so that the materials after
being discharged will give the operator time to cut and place the sheet on a pan,
which is already to be placed in the oven for baking.
The belt can be driven in any way that is most couvenient, so long as it is not
fed too fast for the sheet which is being discharged from the hoppers.
1, is the hopper of the machine having its vertical or upright sides 2, suitably
fastened to the bed of the machine, which is shown mounted on uprights.
Two parallel shafts 8 and 9 extend longitudinally through the lower portion of
the hopper and at their ends are mounted in bearings 4, at the exterior of the
hopper. These shafts are united to rotate in opposite directions by the gears 10
and 11, and one of the shafts has a drive pulley 12.
The hopper is divided into a number of separate compartments for each kind of
material that is to be forced into the sheet, or there may be several compartments
for the material which is to form each layer of the sheet fed from the machine.
As specifically shown in the drawings, the hopper is divided into five separate
vertical compartments 30, 31, 32, 33 and 34, by the vertical partition plates 19,
each snugly fitting in and located transversely of the hopper to shut off one
compartment from the other.
Feed rollers 5 and 6 are rigidly secured on the shafts 8 and 9, and. these rolls
have circumferential grooves 7, to receive said partitions 19, and to divide the rolls
into the divisions 13, 14, 15, 16 and 17, arranged and rotating in the respective
compartments 30, 31, 32, 33 and 34 of the hopper.
The rolls are corrugated or serrulated as shown at 28, so that the surfaces of
the two rolls in each compartment co-operate in forcing and feeding the materials
downwardly..
The bed of the machine beneath each roll is provided with strippers 29, 29, to
strip the material from the surface of the roilers, the space between the stripper and
beneath the meeting edge of the rolls and at the ends secured to the machine is
arranged an elongated box or chamber 21, longitudinally beneath the entire length
of the hopper and all the compartments thereof. The general width of the box is
such as to have the vertical strippers 29, 29, on each side thereof. This box is
provided with the vertical partitions 24, 25, 26, and 27, extending upwardly from
the top of the box and entering the grooves 7, of the rolls, and forming downwardly
continuations of the partitions 19, of the hopper, so that the compartments of the
hopper are continued down between the rolls and below the bite thereof.
Beneath every alternate compartment of the hopper the box is closed and rounded
at the top, see Figures 3 and 7, so that the box forms a dividing or deflecting
obstruction, and the separate streams of material forced from compartments 30, 32
and 34, of the hopper are divided by said box or chamber, and forced down into the
spaces 44, 44, extending the full length of the box, and wherein the separate
streams are united into two flat streams.
Beneath the intervening compartments 31 and 33, of the hopper, said box or
chamber has top openings 20, 20, with out-turned edges 22, 22, which close the
spaces 44, 44, at said openings 20, and between the partitions 24, 25, 26 and 27, so
that the two streams of material from the compartments 31 and 33 are passed
solidly and directly into the long interior of said box or chamber, and there united
into one body, between and separated from the two separated boxes of material in
the spaces 44, 44, on each side of the box or chamber.
A nozzle or supporting die plate 35, is removably secured to the machine bed
longitudinally beneath the passages 44, 44, and the said chamber 21, enclosing the
chamber, except for the narrow discharge opening or slit 38, extends the full length
of the chamber. This plate also has long narrow discharge openings 37 and 39,
registering with the lower ends of the passages 44, 44, and the depending enclosing
walls 40 and 41, are enclosed at the bottom by a plate 42, having a central
downwardly tapered nozzle forined longitudinally of the full length of the
walls 40, 41.
43, is a nozzle secured to and depending from the plate 35, and registering, with

page_text: the discharge slit 38, from the chamber 21, and extending centrally between the
walls 40, 41, centrally into the nozzle 46, and centrally dividing said nozzle 46 into
two like openings on each side of the nozzle 43, and centrally dividing the interior
of the space between the walls 40, 41, into two like spaces 45, 45, communicating
respectively with the spaces 44, 44, and with the discharge openings on opposite
sides of the dividing nozzle 43. It should be noted that three nozzles or discharge
slits are thus formed by the connecting nozzles, 43, 46, and are in the same plane
therewith, and that the material discharged therefrom in three layers will practically
form one sheet when discharged onto the belt or conveyor.
In practical operation dough is usually placed into the hopper compartments 30,
32 and 34, and jam, or jelly, or other preserves are placed in the compartments 31.
and 33. The dough is forced by the corrugated rolls into the passages 44, 44, and
the two masses or sheets formed by the box or chamber 21, are forced by said
corrugated rolls through passages 44, 44, and spaces 45, 45, in two sheets, through
the nozzle 46.
The jelly, jam or other preserves is forced in several streams into the chamber 21,
where it forins one mass, which is forced directly through the nozzle 43, for.ning
a sheet or layer between the two sheets of dough.
I do not wish to limit myself to the particular number of hopper compartments.
shown, as any number may be used.
In practice advantages are obtained by thus dividing up the masses of dough
and preserves to be acted on, particularly where the feed rolls constitute the
entire propelling means for forcing the several screams of material through the
machine.
It should be noted that the parts are simple in construction and can be easily
removed to be cleaned, etc., that the machine showu is adapted for producing a
sheet of three layers of various substances, and that by duplicating the apparatus,
a sheet of more than three layers can be produced.
It is evident that various changes can be made in the forms of construction and
arrangement of the parts described without departing from the spirit and scope of
my invention.
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 [
claim is:-
