page_text: conveyor or carrier, which enables the distance between the mouths of the nozzles
and the carrier, to be quite short, whereby close location of the cakes, and a
complete filling of the entire surface of the carrier is had, without danger of
displacement of the cut sections of dough. Such is not the case with the wire
cutting machines heretofore produced, as the goods have been allowed to drop
directly into pans upon the main carrier, and as these pans are seldom perfectly
flat owing to the bending of the metal of which they are constructed, it has been
found by experience to be impossible to bring the pans close to the nozzles; hence
the goods drop irregularly, upon the edges, &c. and a large amount of available pan
surface is lost; these serious defects I entirely overcome by the use of a preliminary
carrier for receiving the cakes as they are cut, and distributing them uniformly upon
the pans, for baking in the usual manner.

the different bearings and slide-ways. 2 represents the rods which connect the
two sides of the main frame. 3 represents a continuous dough press for supplying
a continuous flow of dough through the nozzle plate 4, the nozzle consisting of a
series of holes therein of such a shape as to give the desired outline to the cakes or
goods either round, square or scolloped, as preferred; the plate 4 being mounted
in ways and made removable or changeable at pleasure.
;
5 is the wire holding frame, particularly illustrated in Figs. 7, 8, 9 and 10. It is
composed of a central shaft 6, to which are clamped a number of fingers 7, the free
extremities of which are perforated for the passage and carrying of an extremely
fine wire 8, the said wire being held at its extremities by stationary arms, 9, which
pass through perforations in the shaft 6 and are secured in place by nuts 10 on
each side of said shaft. By loosening these nuts, the arms 9 may be easily turned
in their bearings, for winding the cutting wire 8 around their extremities, for the
purpose of tightening said wire. The carrying arms 7, are made adjustable longi-
tudinally upon the shaft 6, so that they may be located to pass between the nozzles.
projecting from the plate 4, thus accommodating different locations of the nozzles
upon said plates, allowing the cutting wire 8 to come in close contact with the edge
of the nozzles, and as the wire is carried across this surface, it cuts the outflowing
dough into sections or cakes, which fall upon a carrier, to be hereinafter described.
To make a perfect operation of this act of cutting, the wire holding frame must
travel forward, holding the wire 8 firmly, and cause it to move in a straight line,
close to the edge of the nozzles, in the direction of the horizontal arrow shown in
Figs. 1 and 8. After the cut has been made, it is necessary to drop the wire to a
lower position than it occupies in the forward movement, so that when the recovery
is made, the wire will be low enough to pass beneath the outflowing dough from the
nozzles. This dropping is immediately followed by the lifting of the wire to its
initial position, in a straight line for the operation of cutting. To accomplish this
result, the shaft 6 is mounted in two slide bearings 11, located at each end of said
shaft, upon the side pieces 1 of the main frame. Sliding motion is imparted to the
bearings 11 and shaft 6 by means of two connecting rods, 13, secured at each
extremity of the shaft 6, the other ends of the connecting rods being pivoted to
arms 15, mounted upon a rock-shaft 14. The arm 15, shown in Fig. 11, extends
below the shaft 14, and engages with a rod 16 which is pivoted to a crank-plate 17,
shown in said Fig. 11. The reciprocation of rod 16 causes an oscillation of the
rock-shaft 14 and a consequent reciprocating movement of the wire cutter.
In Fig. 8 is shown an enlarged side elevation of one of the bearings 11 of the
cutting frame. 18 and 19 are stops, mounted upon the bearing 11, each being
perforated for the reception of a set screw 105 and 106. Projecting from, and
firmly secured to the shaft 6, is a pin 20, arranged to come in contact with the inner
ends of the set screws 105 and 106. The full lines in Fig. 8 show this stop pin 20
hard up against the set screw 105, and when in this position the forward movement
of the wire cutter is made. Directly preceding the return stroke of the cutter, the
shaft 6 slightly rotates, dropping the wire 8 and the fingers 7 and 9 connected to
the shaft 6, to the position indicated by the dotted lines in Fig. 8, and when in this

page_text: position the stop pin 20, is in close contact with the set screw 106, said set screws.
regulating the upper and lower position of the cutter. To accomplish this automatic
dropping and raising of the cutter, at the extreme ends of the forward and return
movement of the cutter the following mechanism is employed. In Fig. 9, 21 is a
circular friction plate, firmly keyed to the shaft 6; next to it, and in close contact
therewith is a gear wheel 22. Outside of this gear wheel 22, is a circular flange 23,
which is also keyed to the shaft 6, not firmly, but so as to permit a longitudinal
sliding movement upon the shaft 6, which enables it to press firmly against the gear
wheel 22, making a frictional contact therewith through the interposition of two
friction washers 24, made of suitable material, thus making a frictional contact
between the gear wheel 22 and the shaft 6.
Upon the extreme end of the shaft 6, is a set screw 25 which is screwed into the
end of the shaft 6, and has coiled around it, a spring 26, which bears under the
head of the set screw 25 on one end, and on the other against the washer 27, which
presses by the action of the spring 26, the flange 23, against the gear wheel 22,
making the friction contact above mentioned. This gear wheel 22 engages
with a
stationary rack 28. Surrounding the flange 23, is one of the connecting rods 13.
The operation of this frictional mechanism is as follows: When the connecting
rods 13, push the wire cutting frame in the direction of the horizontal arrow (Fig. 8),
the gear wheel 22, rotates for a short distance in the opposite direction, and carries
the wire holding arm and wire in an upward direction, so that the stop piu 20 comes
in contact with the set screw 105, preventing further rotation of the shaft 6 in that
direction, but the gear wheel 22 continues to turn and pass over the rack 28, over-
coming the friction of the washers 24, and holding the stop pin 20 hard against the
set screw 105, until the forward cut is completely made. The recovery now takes
place, and the backward movement immediately causes the stop pin 20 to come in
contact with the set screw 106, by the action of the friction gear 22 turning the
shaft 6, and as the return niovement continues, the pin 20 will be firmly held against
the set screw 106, thereby causing the wire cutter to drop to its lowest position,
clearing the outcoming dough, from the nozzles. The repeated movement of the cutter
causes row after row of cakes or sections of dough to be dropped upon the endless
preliminary carrier, 29, as illustrated in Fig. 1. This preliminary carrier travels
in the direction indicated by the arrows, around a roller 30 mounted in journals in
the main frame, and running in close contact with a flat plate 31. After passing
around the roller 30, the preliminary carrier 29 returns around a driving drum 32,
then travels in a forward direction around a second drum 33, then backward again,
and around another small roller 34, mounted on a movable plate 35, having slots in
its ends (Fig. 2). In these slots are located fastening bolts, 36, engaging with
projections 107, in the main frame. This construction enables the locating of the
roller 34 close to roller 30, or at a distance therefrom, the object of such con-
struction to be hereinafter explained. After passing around the roller 34, the
preliminary carrier 29, passes downward in an inclined direction, towards a main
carrier, 37, coming in close contact therewith. Preliminary carrier 29, next passes
around and beneath a plate 38, held in position by two sliding bearings, 39,
operated by hand wheels 40, mounted upon screws 108. By this arrangement, the
sluck of the preliminary carrier may be readily taken up. The said carrier now
returns around a drum 41, to pass again beneath the dough nozzles. Two of the
drums 32 and 41, are geared together, power being applied to the shaft of drum 41.
The chain 42 (Fig. 11), after passing around a chain wheel on the shaft of the
Irum 41, passes over a second chain wheel mounted upon the shaft 69 of the
drum 68 of the main carrier apron 37, which also gives motion to said main carrier,
as will be hereinafter explained. Continuing around and engaging with a third
chain wheel mounted upon a cone pulley shaft 43, the chain 42 turns in an upward
direction to the place of starting, that is, the chain wheel mounted upon the shaft
of the drum 41.
Located above the preliminary carrier 29, is a sieve or box 44, which is fixed at

page_text: one edge to a shaft 45, mounted in bearings at the sides of the main frame agitation
is given to this sieve by two ratchet wheels 46, the teeth of which come in contact
with curved arms 47, firmly fastened to the sides of the sieve 44. The rotation of
the ratchet wheels 46 causes the agitation of the sieve 44, which is adapted to
contain granulated material, which by this movement is sifted upon the cakes
which pass underneath upon the preliminary carrier 29. The movement of said
carrier 29 carries the cakes beneath the stamping plate 48, fastened to an oscillating
bar 49, which reciprocates in slide-ways 50, receiving motion by being connected
upon its extreme ends to two rods 51. These rods 51 are attached to eccentrics 52
on each side of the machine, which are keyed to a shaft 53. This shaft 53 is
mounted in bearings in the main frame, and in rotating will cause an upward and
downward movement of the stamping plate 48. To prevent adhesion of this
stamping plate 48, it is provided with an endless belt 54 which passes under the
lower surface thereof, completely covering the same, and around a small roller 55,
and from thence around a driving drum 56, which supplies its motion. This
belt 54, is propelled continuously in the direction of the arrow (Fig. 1), and as it
passes over the driving drum 56, it receives flour from a flour pocket 57, said pocket
being kept full of flour at all times. The preliminary carrier 29, has also a
continuous travel, and it will be readily seen that both the belts 29 and 54, must
travel in union, having the same speed. To accomplish this, the three driving
drums, 32, 33 and 56, must be of the same diameter, and be driven by chain wheels
of the same size. A chain wheel of a given diameter is placed upon the shaft of
drum 32 passing around this wheel is a chain 58, shown by the dotted lines in
Fig. 1. This chain passes around a second chain wheel upon the shaft of the
drum 33, and from thence upward to a wheel upon the shaft of the driving drum 56,
and then returns to the back part of the machine, passing under a tightening roller 59,
to the point of starting. This chain arrangement gives a positive continuous feed
to both of the carriers 29 and 54, the carrier 29 conveying the cakes, and the
carrier 54 flour dust. As the action of the stamp plate 48 is intermittent, and the
preliminary carrier 29 and dust cloth or carrier 54 are continuous, and both travel
in the same direction, the cakes are not displaced by this intermittent stamping
motion. After the stamping or flattening of the cakes has been accomplished, they
pass forward and are liberated from the preliminary carrier 29, by the said carrier
being stripped from under them as clearly illustrated in Fig. 3, which shows a cake
in the act of passing over the stripping device. A modification of this stripping
device is shown in Fig. 4, and performs another function than that of merely
stripping the cakes from the carrier. It consists in placing between the two
rollers 30 and 34, of a bar 60, which forms a bridge connection between the two
rollers 30 and 34 by means of upwardly projecting pieces, 61, placed at regular
intervals on the bar 60, said pieces being designed to carry upon their upper ends
the cakes as they pass forward from one portion of the preliminary carrier 29 to
another. It will be readily seen that all granulated material which drops from
the preliminary carrier 29 must necessarily drop between the rollers 30 and 34,
and will fall into a box 62. When goods, not covered with granulated material
are being made, the bridge bar 60 is removed, and the roller plate 35 brought
closely to the roller plate 31, as hereinabove described.
The cakes on the preliminary carrier 29 travel down the incline, and are
finally deposited in trays or pans 63, which rest upon the main carrier 37, and
move therewith. This carrier 37, has also a positive continuous movement, in
the same direction as the preliminary carrier 29, but has a slightly increased
speed, thereby receiving and placing the cakes upon the pans or trays 63, at a
greater distance apart than they were upon the preliminary carrier 29. This
increased motion is necessary in order to insure a positive transferring of the
cakes from the preliminary carrier 29 to the pans or trays 63. As the pans or
trays are filled, it is necessary to move them out quickly from the preliminary
carrier 29, so that the following pan will be in such a position as to receive

page_text: the cakes, and not to have them drop between two of the pans 63. To
accomplish this forward motion, a hand wheel 64 is provided to give this
forward or skip motion to the main carrier 37, which passes around a roller 65
to the shaft of which is secured the hand wheel 64. The roller 65 performs a
double function; that of tightening the main carrier 37, and also that of
accomplishing the above mentioned skip motion. The shaft of the roller 65 is
mounted in slide bearings 66, having hand screws 67, designed for keeping the
main carrier 37 tightly stretched.
Power is applied to the main carrier 37, by passing it around a driving
roller 68, the shaft 69, of which is mounted in bearings in the sides 1 of the
main frame. At one of the ends of this shaft 69, is keyed a chain wheel,
which engages with the chain 42, from which it receives its motion. Power is
applied to the entire machine from a central driving shaft 70, carrying a
driving pulley 71. This shaft 70 gives motion to the crank-plate 17, which
operates the wire cutter, as before described. This shaft 70 is centrally located
between two other shafts, propelling them by means of gearing, causing them
to travel in the directions indicated by the arrows in Fig. 1. The application
of power from this main driving shaft 70 to the shaft 72, is made by means of
a gear and pinion, 74 and 75. The gear 75 is keyed to one end of the shaft 72,
in the centre of which is a cone 76, all rotating in bearings in the main frame. A
similarly constructed cone 77, is located at the left of cone 76, mounted upon the
shaft 43. These cones 76 and 77 are to give varied speeds to the shaft 43, and as
this shaft 43 drives both the main carriers 37 and the preliminary carrier 29, and
the dust carrier 54, the cut cakes from the nozzles 4, can be located close together,
or far apart on the preliminary carrier, by this differential speed arrangement con-
stituted by the cone pulleys 76 and 77. For providing a hand adjustment of the
belt 78 which connects the cones 76 and 77, a square cross shaft 79 is employed,
and sliding upon this cross shaft is a sleeve 80, having a hand wheel and screw 81,
for securing it at any desired point. The sliding sleeve 80 has two belt forks 82
and 83, one engaging with the upper part of the driving belt 78, and the other with
the lower part of the said belt. The sliding sleeve 80 with the belt shifters attached,
gives a positive location and holding of the driving belt 78, at any desired point,
and consequently any required speed of the connected parts can be obtained.
Power is applied to the continuous dough press as follows: To the shaft 70,
just inside of the main frame, is secured a driving pinion 84, which engages with a
large gear 85. The gear 85 is keyed to the shaft 73. At the end of the shaft 73
is a slotted, adjustable crank 86, carrying a sliding crank pin 87, which may be
adjusted by the hand screw 88. Journaled to the crank-pin 87, are two connecting
rods 89 and 90, the upper ends of which are pivoted to two oscillating pawl arms 91
and 92. On the inside of each of these arms 91 and 92 are pawls which engage
with the ratchet wheel 93. The rotation of the crank 86, will give any desired
motion to the ratchet wheel 93, more or less, in accordance with the adjustment of
the crank-pin 87. The ratchet wheel 93 is keyed to a shaft 94 which carries the
feed roller 95 of the dough press 3, and propels the same, causing the dough to flow
through the nozzles 4, the desired amount being obtained by means of the adjustment
of the crank-pin 87.
From the crank shaft 73 motion is transmitted to the stamping device by means
of a chain wheel 96, keyed to the shaft 73. This chain wheel engages with an
endless chain 97, thereby transmitting power to the smaller chain wheel 98, which
is keyed to the eccentric shaft 53. Power is also taken from the shaft 73 to agitate
the sifter 44 by means of an endless chain 99.
For dusting the preliminary carrier 29, a box 100 is provided, the bottom of which
is formed by the carrier and roll 41.
In order to accurately adjust the stamping plate 48, for flattening the cakes, two
studs 101 are fastened to the ends of the stamp plate, which project upward through
holes in the cross-head 49, said studs being provided with jam nuts 102, by which
the height of the stamp may be accurately regulated.
