Improvements in Weighing and Package Filling Machines.
The J
I, HENRY HARRIS LAKE, of the Firm of Haseltine, Lake & Co., Patent Agents,
45, Southampton Buildings, in the County of Middlesex, 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:-
My invention relates to improvements in weighing and package filling
machines, one object of my invention being to combine with two hoppers,
mechanism to carry packages successively beneath both hoppers and to have a
package underneath each hopper at the same time and mechanism to close the
How from the first hopper independently of the weight or quantity of goods
in the package, while the second one is closed by the weight. Another feature
of my invention relates to the contact mechanism in an electrically, operated
machine in which a main and a supplemental contact is employed, the main
contact being closed by mechanism actuated by the scale beam and opened by
mechanism actuated by the closing of the contact, and the supplemental contact
being actuated by separate mechanism which is set in operation after the, main
contact is made to both close and open the contact, the main contact being
opened before the supplemental contact is opened. Another feature relates to
the valve closing mechanism of the first hopper. The several features of the
invention will be fully described in the specification and particularly pointed
out in, the claims at the end thereof.
. The machine illustrated in the drawings as embodying my invention is of the
class in which the mechanism for actuating the valve is operated by a double
solenoid, although some of the features of my invention are adapted for use in
weighing machines in which the valve is operated by other means than electricity,
as for instance a pneumatic machine.

1 is the first hopper through which the package is partially filled, and 2 the
second hopper through which goods are fed to top off. 3 is the main driving
shaft operated by belt pulley 4. On the opposite end of the driving shaft 3
from the pulley is a sprocket wheel 5 connected by a chain 6 with the sprocket
wheel 7 on the short shaft 8 supported by a bracket 9 attached to the frame 10.
The mechanism for closing the valve of hopper will now be described.
The hopper 1 has a swinging valve 11 pivoted at 12 and having a lever 13
connected by a link 14 with rod 15 which is operated by shaft 8 through inter-
mediate mechanism to open and close at certain intervals, as will be particularly
described. Said rod 15 is connected by link 16 with slide rod 17 which slides
in fixed sleeve 18. Said rod is partly cut away toward the rear end forming a
shoulder 25. At its rear end slide rod 17 has a pin 19 which enters a longi-
tudinal slot 20 in the arm 21 of rock shaft 22. Fixed to a short shaft 23 pass-
ing loosely through sleeve 31 is an arm 24 which extends down into the path of
the shoulder 25 on the slide rod 17 and engages therewith. Projecting from
the arm 24 is a stud 26. Mounted loosely on the shaft 8 is a disk which is
preferably formed of two disks 27, 28, clamped together by screw 29 so as to be
adjusted with relation to each other for purpose to be described later. Pro-
jecting from the face of disk 27 is a stud 30. (See Fig. 9). Fixed to the
shaft is a ratchet wheel 32 with which a spring pivoted pawl 33 engages
causing the disks 27 and 28 to rotate. When the disk 27 is rotated the stud 30
engages with the stud 26 and causes the arm 24 to rock forward, engaging with
the shoulder 25 on the slide rod 17, causing it to slide forward and thereby
operating the connecting rod 15 and closing the valve of hopper 1. The arm 24
from which stud 26 projects is hung a little forward of a vertical line passing
through the axis of the disk 27, and the center of stud 30 when at its highest
position is a little lower than the center of stud 26 so that when the arm 24
is swung forward a short distance the stud 30 will ride under stud 26, thus
limiting the extent of forward movement of the slide rod 17. On rock shaft 22
is a dog 34 which engages the heel of pawl 33 after the stud 30 has passed
under stud 26, and trips the pawl from the ratchet so that the disks 27 and 28
remain stationary and the ratchet continues to revolve with its shaft until the
dog 34 is turned out of engagement with the pawl. This disengagement is
effected by the rocking backward of shaft 22 which occurs when the slide rod 17
is reciprocated backwards as will be described hereinafter. When the dog 34
is released the spring 35 will throw the toe of the pawl again into engagement
with the ratchet and cause the disks to rotate again, bringing the studs 30 and 26
into engagement with each other and sliding the rod 17 forward again. The
backward reciprocation of the slide rod is produced by connections with the core
of the solenoids and opens the valve. The length of time that it remains open

page_text: will depend upon the time that it takes for the stud 30 to come around into
engagement with stud 26. It is obvious that by varying the relative position
of the pawl 33 on disk 28 to stud 30 on disk 27 that the length of rotation of
the disk after dog 34 is released from the pawl before stud 30 will engage with
stud 26 to close the valve of hopper 1 will also be varied, and therefore the
quantity of goods which flow through will be varied. It is necessary, that it
should be regulated so as to close at least as soon as the valve of the second or
topping out hopper closes.
The mechanism and manner of opening the valve of hopper 1 is as follows:
The two cores 36, 37, of the solenoids are connected by a union 38 which has
a cross head 39. Pivoted to this cross head is a dog 40 which when the cores
36, 37, of the solenoids are in their forward position and the valves are closed
rests in front of the feather 41 which projects up from the slide rod 17. The
dog 40 also rests upon the cam 42 which is fast to the sleeve 18. When the
cores of the solenoids move toward the rear the dog 40 engages with the blunt
end of feather 41 and slides back the rod 17 and connecting rod 15, thus opening
the valve of hopper 1. As the cores approach the rearmost position the dog 40
rides up on the inclined face of the cam 42 and is raised from front of the
feather so that the backward movement of the slide rod is stopped. When the
cores move forward again the dog 40 rides forward over the cam, being kept
down by a spring 208 (see Figs. 10 and 11) so that when it reaches a position
forward of the feather 41 it will be down ready for engagement again with the
feather at the next backward movement.
The valve of the second hopper is opened and closed in the following manner:
The valve 43 of the topping out hopper 2 has an arm 45 pivoted at 181 and
is operated by a rod 44 pivoted at its forward end to said arm 45. Said rod 44
passes through sleeve 46 hung from cross head 39 and has collars 47, 48, against
which said sleeve 46 strikes to push the said rod back and forth as the cores of
the solenoids reciprocate, thus opening and closing the valve of hopper 2.
The packages are placed on a travelling belt 60 which delivers them one at
a time to a sliding carriage 61. The carriage then moves to a position where
the package is engaged by the carrier fingers 62 projecting from the inter-
mittently revolving gear ring 63 and pushed along the segmental track 64 to
position under the hoppers as will be hereinafter described. When a package
is 'removed from beneath hopper 1 to the scales 182 beneath hopper 2, another
empty package will at the same time come into position beneath hopper 1.
The carrier ring 63 gears with pinion 65 on the vertical shaft 66. Said shaft 66
is operatively connected with the main shaft 3 by clutch 67 and bevel gears 68, 69.
(See Figs. 2, 3, and 4). At each rotation of the clutch and of the vertical
shaft 66 the clutch becomes disengaged and the said shaft 66 and pinion 65 are
brought to a rest and gear ring 63 is also brought to a rest, thus giving to the
ring 63 a rotation through an are whose length depends upon the size of
pinion 65. The clutch remains disengaged until again made operative by
mechanism operated by the core of the solenoid when the latter moves in a
direction to close the valve. This is accomplished through pivoted lever 209
which is engaged by a boss 207 on slide rod 183, said slide rod being engaged
by pawl 205 on cross head 39 and pushed forward as the solenoid moves to close
the valve. In the drawings the slide rod is shown in its retracted position
behind the pawl.
ས་
When the rear solenoid is energized the movement of the solenoid actuates
mechanism which opens the valves of both hoppers, and when the forward sole-
noid is energized mechanism is actuated to close the valve of the hopper above
the scales, the valve of the first hopper being closed mechanically by other
mechanism independently of the solenoid. The contact mechanism for the rear
solenoid is that shown at the front of the machine, and the contact mechanism
for the forward solenoid is located at the rear part of the machine. The valve
opening contact is actuated by the packages, it being necessary in the form of

page_text: construction which I have shown to have packages come under both hoppers
before the valves will open. The valve closing contact of the second hopper is
actuated by the tipping of the scale beam.
I will now describe the contacts and their actuating devices more particularly
taking first the forward or valve opening contact. (See Figs. 7, 8, 12 and 13).
The contact mechanism consists of a sliding contact piece 70 which when it
slides forward passes between and contacts with the jaws 71, 72, which form the
two terminals of the circuit. The sliding contact piece 70 is mounted in a
holder 73 which is secured to the slide rod 74 by clamps 75, the holder being
insulated therefrom by insulators 76. The rod 74 slides in the sleeve 77 which
is slotted in the under side to allow play of the contact holder 73 and clamps 75.
In Fig. 7 the sleeve 77 is shown partly broken away on its upper side. Said
sleeve is secured to the insulated base 190 which is secured to the frame of the
machine. The slide rod is normally held by a spring 78 in a position to keep
the contact open as shown in Fig. 12. The terminals jaws 71, 72, to which lead
the wires 201, 202, are mounted in holders 191, 192, on insulated pivots 79, 80,
having torsion springs 81, 82, which tend to draw them together, but the
When
jaws are kept separated by the block 83 of non-conducting material.
the rod 74 slides in a direction to make the contact the beveled end of contact
piece 70 will enter between the jaws which will yield slightly, their springs,
however, keeping the contact unbroken. A collar 84 fits loosely over the rod 74,
being prevented from endwise movement by a clamp 85. It is keyed to the
slide rod by a pin 86 which enters a spline 87 in the rod. An end view of the
rod is shown in Fig. 2. The pin does not interfere with the endwise reciprocation
of the rod, although the collar has no endwise movement. When the collar is
rotated, it causes the rod also to rotate. A lever 88 is fulcrumed at 89. (See
Figs. 8 and 12). Its upper end enters a hole 90 in the collar 84 with which it
has a sort of rolling fit so that when the lever 88 is turned on its fulcrum it will
cause the rod 74 to roll. The lower end of said lever SS is connected to a link 91
which at its other end (see Fig. 7) is connected to the arm 92 of the double
lever 92, 93, the two arms of the lever being hinged together at 94 and the
arm 93 being pivoted at 95. It will be seen that the arm 93 is curved substan-
tially to conform to the curve of the inner edge of the track and that the arm 92
has a portion 96 near its end which protrudes over the track. It will be plain
that if a package 97 passes along the track and crowds against the protruding
portion 96 pushing it out of the path, and if there is no package or other pressure
against the arm 93 to prevent it from moving inward, that the outer end of link 91
which is free to swing horizontally in an arc of a circle with its outer end as a
center, will swing around and the double lever will bend at its hinge 94, pushing
in over the track, as shown in dotted lines in Fig. 7. If, however, there is
also a package on the track bearing against arm 93 when the package 97 passes
part 96 the lever cannot be bent at the hinge, and the link 91 instead of swinging
in an arc will be pushed endwise away from the track. This endwise movement
of link 91 will turn rod 88 on its fulcrum and give to collar 84 and slide rod 74
a rolling movement. Fulcrumed in bracket 98 is a lever 99 (see Fig. 2) whose
upper end engages with a grooved collar 100 fixed on slide rod 44 so that when
the slide 44 moves back and forth with the movement of the solenoids, the
lever 99 will be turned on its fulcrum. The pin 86 which keys the collar 84 to
rod 74 projects upward into a position in front of the lower end of lever 99
when the rod 74 is pushed in to make the valve opening contact. Projecting
from the slide rod 74 at or near its other end, but in a different plane from pin 86
is pin 101. (See Fig. 7). Carried on the vertical shaft 66 near its lower end
is a cam 102 having a point 103 which at each revolution of the shaft engages
with the pin 101 if the slide rod 74 be rolled as already described when packages
are beneath both hoppers.
The operation of the machine is as follows: The valves being closed, and
contacts open, the power is put on and ring 63 revolved until packages reach

page_text: both hoppers. When the second package arrives against arm 93 and the first
package passes the projecting portion 96 of the double lever, lever 88 is actuated
through rod 91, as already described, to roll rod 74 until pin 101 turns up into
path of cam 102, so that when cam point 103 comes around it will engage with
said pin 101 and pull slide rod 74 until contact piece 70 enters jaws 71, 72,
making the valve opening contact. As soon as this is done, the solenoid will
be energized and move in a direction to open the valves. When the slide rod 74
is rolled up to bring pin 101 into engagement with cam point 103 it also brings
pin 86 up in front of the line of movement of lever 99, and when the rod 44
moves to the rearward to open the valve it turns lever 99 on its fulcrum as
already described. The lower end of said lever is thereby pushed against pin 80
and turns rod 74 so as to trip pin 101 from engagement with cam 102 and the
spring 78 throws slide rod 74 back to its normal position, thus opening the
circuit. .
The valve closing contact mechanism is located at the rear part of the machine
and consists of a double contact, one of which is broken in advance of the other,
each contact mechanism being operated independently of the other, the supple-
mental contact being for the purpose of relieving the sparking of the main"
contact. The main contact is preferably metallic, and the supplemental contact
carbon which is cheaper and can be easily replaced when worn out. (See Figs. 7,
8, 14-17). The main contact piece 110 is mounted on an insulated lever 111
pivoted on pivot 112 in the bracket 113 secured to the fixed ring 114, and con-
tacts with the two terminals 115 and 116. In order to ensure a contact the
terminals are provided with springs 117, 118, between which the contact
piece 110 fits. The torsion spring 119 around pivot 112 tends to keep the con-
tact closed. Wires 120 and 121 connected with the two poles of the forward
solenoid are connected with the terminals 115 and 116 respectively, by the
binding screws 122, 123. The terminals 115 and 116 are insulated from the
bracket 113 by insulation 124. Mounted loosely in sleeve 125 projecting from
bracket 113 is a shaft 126 carrying cam 127 which extends into the path of the
package moving fingers 62 so that when one of said fingers rides over the cam
the cam shaft will be partially rotated. Projecting from the said cam shaft is a.
pin 128 which engages in a slot 129 in the pin 130 which passes loosely through
a vertical hole in the horizontal arm of bracket 113 and directly beneath the
contact lever 111. When one of the fingers 62 rides over the cam 127 it depresses
it as shewn in Fig. 17 and the cam shaft 126 is rolled and the pin 128 raises
pin 130 which in turn lifts contact lever 111 and breaks the main contact.
Pivoted at 131 is a lever 132 whose upper end rests against the flat side of the
thin lower part 196 of pin 130 when said pin is in its lowermost position and
said lever is thereby prevented from hanging plumb. As soon as pin 130 is
raised out of the way, lever 132 swings into plumb, or as nearly so as permitted
by the stop pin 133, so as to bring the upper end of said lever under the end 196
of said pin 130 and hold it up. The counter-weight 134 quickens the action
of lever 132. The engagement of the lever 132 with pin 130 is so delicate,
however, that the tension of spring 119 which tends to throw down the pin 130
will trip the lever unless the latter is held in some way. This is done by the
lower end of lever 132 bearing against the rear end 130 of the auxiliary scale
beam 135 when the scales are in their normal position. As soon as the scale
beam is tipped by a weighted package the lever 132 is tripped and the contact
lever drops, making the circuit through the forward solenoid and closing the
valve of hopper 2, the valve of hopper 1 being closed by other means already
described.
The supplemental contact device consists of a fixed contact piece 140 in
electrical connection with the terminal 115 (see Figs. 7 and 14), and a swinging
contact piece 141 in electrical connection with terminal 116, and mechanically
operated by mechanism actuated by the moving gear ring. (See Figs. 7, 8, 12
and 16). These supplemental contacts are preferably carbon. The movable

page_text: contact 141 is in a holder 142 which is pivoted by pin 195 to a hub 144 which
swings horizontally on pivot 143, the movable contact piece making a grazing
contact with fixed contact piece 140 when it is closed. A spring 197 around
pivot 195 makes the contact between 140 and 141 elastic. Projecting from the
hub 144 of said holder 142 is an arm 145 to which is pivoted a nipple 146 with
which is connected rod 147. The other end of connecting rod 147 is; pivoted to
a vertical rock shaft 148 at 149. The movable contact 141 is insulated from the
shaft 148, preferably by an insulating bushing to the nipple 146. Said rock
shaft 148 is mounted in a sleeve 154 secured to a bracket 153 which is fastened
to the fixed ring 114. (See Figs: 7 and 8). On the upper end of shaft 148 is a
rocker arm 150 pivoted to one end of a pitman 151 which at its other end is
pivoted to a crank 152. (See Figs. 1, 2, 4-7). Said crank 152 is on the upper
end of a short vertical shaft which turns in bearings in the bracket 153, and
which has on its other end pinion 155 which meshes with the large gear ring 63.
Said pinion has just teeth enough to make one revolution while the large ring
moves through an are equal to the distance between the package moving fingers.
At each revolution of said pinion, the crank 152 makes a revolution, giving
to the rocker arm 150 and rock shaft 148 a rocking movement which recipro-
cates the connecting rod 147 and thereby rocks the movable contact holder 142
giving to it a swinging, movement and causing it to close and open at each
revolution of the pinion 155 and thereby making and breaking contact at each
revolution. As we have already seen, the main valve closing contact is actuated
by the tipping of the scale beam under a full load. This energizes the rear
or valve closing solenoid so that it moves forward and actuates the mechanism
which sets the large gear ring in motion. When the large ring begins to move
it rotates pinion 155 thus actuating the supplemental contact which therefore
does not make its contact until after the main contact is made. When the large
ring has moved far enough for one of the package moving fingers to engage
with cam 127 it begins to lift the main contact, but said contact does not break
until after the supplemental contact is made. The supplemental contact begins
to withdraw after the pinion has made a half revolution but does not break
entirely until after the main contact is broken. About the time a package
reaches the scale pan under the second hopper and another package is under the
first hopper the valve opening contact will be made as previously described.
A
There are guide rails 160 at each side of the track 64 and of the belt 60. It
will be observed that the carrier belt is not directly in line with the track.
sliding carriage 61 slides in ways 162 transversely to the carrier and the track.
(See Figs. 2, 4, 5 and 6). The packages are fed from the carrier belt directly
onto the said carriage when the carriage is in its outer position, as in Fig. 5.
The carriage holds but one package at a time. A connecting rod 163 is pivoted
at one end to said carriage and at its other end is pivoted to an arm 164 pro-
jecting from rock shaft 148. While the said rock shaft turns at the first half
of its period of movement to make the supplemental contact, it draws forward
connecting rod 163 and carriage 61 and the package which is on the carriage
is brought in front of the package moving finger next in turn.
As the ring
turns, the finger engages with said package and pushes it from the carriage
onto the track, as in Fig. 6. The carriage retracts during the last half of the
period and comes back into its first position. Rising from the carriage is a
guard 165 which when the carriage moves forward bars the passage from the
carrier belt so that no other package can be delivered until the carriage returns.
It also has an end rail 166.
Pivoted to the side of the fixed ring 114 is a spring latch 170 extending up
into the path of the package-moving fingers 62. The latch allows the fingers to
freely pass over it in a forward direction, but prevents backward movement.
The hoppers are not necessarily located as near together as shown in the
drawings. They may be located at any angle apart.,
In Fig. 18 is shown diagrammatically the electrical connections between the

page_text: solenoids, dynamo and contacts. The circuit is made from one pole of the
dynamo 220 to one pole of the rear or valve opening solenoid 221 through
wire 222, branch 201, forward contact mechanism which has already been fully
described, and wire 202. The circuit from the opposite pole of the dynamo to
the other pole of the rear solenoid 221 is through wire 223 and branch 224.
The circuit from the first pole of the dynamo to one pole of the forward or valve
closing solenoid 225 is made through wire 222, branch 120, the rear contact
mechanism already described, and wire 121. The circuit from the other pole
of the dynamo to the other pole of the forward solenoid 225 is through wire 223
and branch 226. Both contacts are shown open.

at each period of movement of said ring the carriage will move forward into
position where one of the said fingers will transfer the package from the carriage
onto the said track, and the carriage will then be moved back again, and means
for preventing the delivery of packages from the carrier to the carriage while
in its forward position, substantially as described.
10. In a weighing and package filling machine in which the valve which
controls the flow of goods is actuated by a solenoid, mechanism which makes
and breaks the circuit, comprising a sliding contact piece, a slide rod which has
a longitudinal movement to actuate the contact piece and which is also capable
of turning on its axis, a spring which normally holds said contact piece out of
circuit, a rotary cam which engages with said slide rod and causes the contact
piece to close the circuit, the solenoid thereby being energized, and a lever
actuated by the sliding core of the solenoid to turn said slide rod on its axis
and disengage it from the cam, whereby its spring retracts said rod and breaks
the circuit, substantially as described.
11. In an electric weighing and package filling machine, a double contact
mechanism consisting of a main contact and a supplemental contact, the main
contact being made by the tipping of the scales, the supplemental contact being
made by mechanism set in operation by the closing of the main contact, mech-
anism which breaks the main contact after the supplemental contact is made,
and independent but co-operating mechanism which breaks the supplemental
contact after the main contact is broken, substantially as described.
12. In an electric weighing and package filling machine, an intermittently
rotating ring, a double contact mechanism in the valve closing circuit con-
sisting of a main contact and a supplemental contact, mechanism actuated by
the tipping of the scales which makes the main contact, mechanism which
causes the said ring to rotate after the main contact is made, mechanism actuated
by said ring after it begins to move to make and break the supplemental contact,
and other mechanism actuated by the moving ring to break the main contact
after the supplemental contact is made, and before the supplemental contact is
broken, substantially as described.

13. In an electric weighing and package filling machine, an intermittently
rotating ring, a double contact mechanism consisting of a main contact and a

page_text: supplemental contact in the valve closing circuit, a pivoted lever on which the
main contact is mounted, a spring which throws said lever to make the contact,
a pivoted trip lever engaged by the scale beam, a lifting pin engaged by said
trip lever which engages with said main contact lever and holds the contact
broken, and which is tripped by the tipping of the scales whereby said spring
throws the contact lever, mechanism which sets the said ring in motion when the
contact is made, a cam lever which is actuated by the moving ring and lifts
the contact lever through said lifting pin, the trip lever again being engaged
by the scale beam, a pinion gearing with said intermittently rotating ring, and
intermediate mechanism whereby the rotation of the pinion causes the supple-
mental contact to be made after the main contact is made, and then breaks it
after the main contact is broken, substantially as described.
14. In a weighing and package filling machine having two feed chutes and a
valve for each feed chute, mechanism which opens both valves, said valve open-
ing mechanism including therein a jointed lever, the two members of said lever
engaging respectively with packages when in position under both feed chutes,
said mechanism being operative to open the valves only in combination with
packages so positioned under both chutes simultaneously, substantially as
described.
15. In a package filling machine, the combination with a hopper or feed
chute, of mechanism which closes the outlet of the hopper or feed chute after it
has remained open a predetermined duration independently of the weight or
quantity of goods and means for adjustably varying the duration, substantially
as described.
16. In a weighing and package filling machine having two hoppers, mechanism
which carries the packages first to a position where one hopper discharges
directly into the packages and partially fills the same, mechanism which closes
the outlet from the first hopper after a predetermined open period irrespective
of the weight or quantity of goods, mechanism which then transfers the pack-
ages to the scales, mechanism which then opens the flow from the second hopper,
directly into the packages while on the scales and mechanism which is actuated
by the tipping of the scales to cut off the flow, substantially as described.
17. In a weighing and package filling machine having two hoppers, mechanism
which carries the package first to a position where one hopper discharges
directly into the package, mechanism which cuts off the flow from the first
hopper when the package is partially filled, mechanism which then transfers the
package to the scales, mechanism which opens the flow from the second hopper
directly into the package while on the scales, and mechanism which is actuated
by the tipping of the scales to cut off the flow substantially as described.
