Improvements in Machinery for. Weighing Substances and Filling
Packages therewith, and for Settling or Shaking Down the
Material in Packages,
:
I WILLIAM THOMAS WHITEMAN of N° 7 Staple Inn in the County of
Middlesex Patent Agent do hereby declare the nature of the said invention for
"IMPROVEMENTS IN MACHINERY FOR WEIGHING SUBSTANCES AND FILLING PACKAGES
THEREWITH AND FOR SETTLING OR SHAKING DOWN THE MATERIAL IN PACKAGES
to be as follows:-
"
This invention has reference more particularly to machines for filling packages
or cartons of card board paper and other material with equal weights of granular
substances such as bird seed hominy oatmeal coffee and the like or of powdered
substances such as corn starch flour and the like and also to machinery for settling
or shaking down the matters in the packages but is applicable in whole or in part
to other machinery.
It is mainly designed as a modification of and improvement upon the machine
described in the specification of Letters Patent granted to me and bearing date the
31st day of October A.D. 1882. N° 5195 although the present improvements or
some of them are or may be applicable to other machines.
In the patented machine a number (four) of weighing scales are carried by a
revolving table. The pan or plate of each scale is adapted to receive and support a
carton or package. A hopper is supported above the scales and revolves with the
table. It has a series of openings one over each scale pan or or scale plate so that the
material in the hopper may flow through the opening into the carton or package on

page_text: the scale pan or plate. At each delivery-opening there is a gate controlled by the
corresponding weighing scale so that when the pan or plate thereof is depressed the
gate is advanced to close the opening and cut off the delivery of material to the
package and when the scale pan or scale plate is raised the gate is withdrawn to
uncover the opening and allow the delivery to recommence.
A latch is provided for holding down the scale-pan that it may not rise and
uncover the delivery opening when relieved of the weight of a full carton or
package until a new one is placed on the scale-pan. This latch is arranged to be
operated automatically by contact with the package. There are also sliding spindles
one for each weighing scale which support the scale beam with the scale pan
depressed and supply gate closed during the removal of a full package and the
insertion of an empty one.
:
Tapping apparatus (one for each weighing scale) are provided for tapping the
packages on the scale pan when desired. They are operated from the aforesaid
spindles which are revolved by contact with a friction wheel.
In the said specification it is also pointed out that a single weighing scale which
does not rotate can be used in connection with a suitable hopper where a small
machine is desired.
The object of the present invention is mainly to secure greater accuracy in the
weighing by an ordinary supervision although other objects are the simplification
of the machine and the adapting it to fill different sized packages and to use with
different substances and the perfecting of the tapping apparatus.
It is found that a flat scale-pan retains material which accidentally escapes in small
quantities until at length sufficient is collected to make an appreciable difference in
the weighing. To remedy this difficulty the horizontal area of the package support
part is made small or, not materially larger than the bottom of the package or
carton which rests thereon and below this support is a conical skirt which extends
over the bearings of the scale pan below. If any of the substance being weighed
escape it falls upon the skirt and does not adhere except in very small quantities.
The skirt also by delivering it outside prevents its lodging upon the scale beam.
In order that the scale may be the better adapted to filling different sized packages
the package support is made vertically adjustable so that it may be brought nearer
to or removed farther frem the delivery opening or spout.
--
The gauge plates for upholding the package in filling.are mounted upon rods
projecting laterally from the package support, and are made adjustable thereon.
The latch for holding down the scale-pan is provided with an adjustable contact
finger to be struck by the package when inserted. The object of the adjustment is
the better to accommodate different sized packages.
The latch is provided with a stop to limit the outward movement or movement
of the same when the package is inserted.
The latch instead of being wholly behind the scale-pan as heretofore is placed
partly in front and partly behind the pivot being about on the middle line of the
scale pan.
The weighing scale is provided in addition to the ordinary adjustable weights
with a supplemental weight in the form of a nut adjustable on a screw rod
Weight nuts have heretofore been used in the ordinary platform scales but the
particular construction and arrangement (hereinafter fully set forth) whereby nut
weights are applied to small automatic scales is believed to be new.
In order to render the scales independent of the centrifugal force developed by
the rotation of the revolving table balance weights are connected with the scale-
beams on the opposite side of the fulcrum from the gate which controls the supply.
The weight nut before described is or may be arranged to act as a centrifugal
balance weight. When the power is steady it is not necessary to use the centrifugal
weights as the centrifugal force being constant it can easily be compensated for.
The scale bearings at the base of the rod which supports the supply gate are
protected by a shield which prevents the material weighed from lodging thereon or
therein.

page_text: To prevent the moveable parts of the scale from rebounding when the scale pan
descends with its load which rebounding would be apt, partly to open the supply
gate and thus deliver an over weight into the package the brush at the front of the.
delivery opening is arranged to make contact with the supply gate so as to give a
slight friction sufficient to prevent a rebound of the moving parts of the scale. The
brush thus acts as a friction device which comes into play at the end of the supply
gate's movement.

::
It is found desirable with some substances in order to prevent the gate from
wedging to use a brush at the back as well as at the front of the delivery opening.
This is not broadly new in automatic weighing scales and is only claimed herein in
combination with the supply gate carried by a rod fixed at the lower end in the
scale-beam.
D
The delivery openings are provided with removeable bushings of frusto conical
form this form being found in practice to be better than the flat or plate bushing
described in the specification of the aforesaid Patent.
511
A hopper centrally placed over the axis of the revolving table and provided with
shoots radiating therefrom and descending towards the weighing scale is found for
substances of a ready flowing or granular nature to be a more convenient form than
the annular hopper of the patent. The delivery openings are at the outer or lower
ends of the shoots.
To prevent the scale pan and scale beam from sliding over their bearings which
they are apt to do when the knife edges enter, the ordinary circular openings in the
supporting arms the edges of the said openings are inclined at such an angle that
they will not ride upon the knife edges nor the knife edges upon them.
For filling packages of card board paper and other materials with equal weights
of powdered substances such as corn starch flour and the like inclined blades are
provided for forcing or crowding the substance in the hopper into the said delivery
opening or openings.
By this means the flow of the powdered substance through the delivery openings
which does not readily take place by the action of gravity alone on account of the
lightness of the material and its tendency to pack together is assisted so that a
free delivery is obtained whenever the supply gates are withdrawn.
Heretofore it has been common. to feed light material through a hopper opening
by means of a screw but a screw hopper has not been combined with an automatic
weighing scale having a supply gate connected with and operated by the scale...
It is found that the compacting of the powdered substance above the supply
gate does not interfere (the parts being properly proportioned) with the movements
of the gate but on the contrary that it bas a beneficial effect in preventing the
scale from rebounding when the load comes down the scale pan and closes the
gate.
.
The
It is not found necessary to use brushes with powdered substances.
annular form of hopper is preferred the inclined blades being supported therein by
a stationary ring.
For further assisting the powdered material through the delivery openings there
are raised pieces at each opening of the revolving annular hopper. They as it were
plough their way through the powder which is compacted by the inclined blades
and also by them held back so that it is not carried around so fast as the hopper
revolves.
These raised pieces are made adjustable so as to act as valves to regulate the size
of the delivery openings. In this case the removeable bushings are not used.
A cam is provided for actuating a valve so as to diminish the size of the delivery
opening after the bulk of the charge has been weighed. Thus both the rapidity,
of weighing due to the delivery of a large stream and the accuracy due to the
delivery of a small stream are measurably secured. This cam need not be used.
For maintaining an uniform quantity of the powdered substance in the hopper
the latter is supplied through a spout in which is a cut off for regulating the flow
and the position of this cut off is controlled by a float which is acted upon by the
໑

page_text: substance in the hopper. When the substance accumulates to a sufficient depth it
stops the flow and as the substance is drawn off it reopens the valve and lets the
. hopper fill up again.
An improved tapping apparatus or attachment for shaking down the substance in
the package is used the said apparatus or attachment consisting of one or more
tappers or tapping arms arranged to strike the bottom of the package.
It is found that practically such tapping is much more effective in shaking down
the substance when the blows are made on the sides of the package.
The tapper is combined with a belt conveyor on which the packages are placed
after removal from the scales.
:
When this scale is used without the cam and spindle as in a small machine the
beam descends suddenly and with the ordinary scales it is apt to rebound and con-
tinue in vibration for some time. The rebounding and vibration interferes with
the delivery of the material and unless the scale come to rest before the charge is
weighed out it interferes also with the accuracy of the weighing causing the gate
to close sooner or later than it ought. To prevent this rebounding of the scale on
opening the gate a stop is placed under the weighted end of the scale beam so as to
be struck by the same. It seems to absorb the energy of the moving beam and
prevent rebounding. Whatever the explanation it causes the beam to come to rest
much sooner than it otherwise would.
In order to weigh rapidly it is desirable to deliver a larger stream at first and
when the bulk of the charge has been delivered to reduce the stream so that the
gate in closing shuts off a comparatively, small stream. Heretofore it has been
proposed to cause the scale to effect such a reduction in the flow of material by
closing a valve and the use of a cam acting upon a valve for this purpose is herein-
before set forth: In a hand machine there is no power to operate a cam.
The desired result is effected according to this invention without the use of
moveable valves by combining with a spout or hopper having a contracted orifice a
funnel or small reservoir which is provided with a larger delivery opening to be
closed by the supply gate of the automatic weighing scale and into which the
spout or mouth of the hopper projects leaving a suitable space below the con-
tracted orifice. When the supply gate is closed the material descends through the
orifice and fills the funnel or reservoir to its own level. Then the material in the
funnel or reservoir seals as it were the orifice and prevents more material from
passing out When the supply gate is opened the material escapes rapidly and runs
completely out of the funnel or reservoir before the scale receives its charge.
Then the delivery continues from the contracted orifice until the supply gate
closes:
It is desirable to be able to vary the quantity of material in the funnel or
reservoir in order to suit charges of different weights. This can be done by
adjusting the spout or hopper vertically so as to leave more or less distance
between its orifice and the delivery opening in the funnel or reservoir It can
also be done by making the hopper removeable so that it can be replaced by one
which descends lower or not so low in the funnel or reservoir and which may also
have a smaller or a larger orifice. It is best. effected by the use of removeable
bushings of frusto conical form which fit in the hopper and which may be of various
lengths with various sized orifices. The smaller the quantity weighed the smaller
should be the orifice in order to secure an accurate weighing.
When granular material is fed through a long tube or spout it is found that the
pressure will affect the flow through the orifice and produce inequalities in the
weighings. To prevent this a plate or disc is supported at the mouth of the tube
or spout It takes off the pressure due to the column of the material. The material
passes over the edges of the disc or plate.
In many cases it is not desirable or practicable to support the packages or
receptacle to contain the material weighed on the scale pan as for example if
the material is to be weighed independently of the package or when the material
is. to be packed in bags. To meet such cases the following arrangements are used.

and is adapted to be discharged as well as receive the material weighed. In con-.
nection with such a scale pan a retaining latch is provided for holding the scale.

pan with a single receptacle two or more of them are employed and they are so.

discharging. A scale pan for an automatic scale adapted to discharge the material
weighed is not new and grain meters have been made with two grain receptacles
which receive the grain from a common spout and are adapted the one to discharge
while the other is filling The latch arrangement to such a scale and also the
particular construction and combination of parts in and about the scale pan are
however believed to be new.
The receptacles are open at both ends and are connected with a spider frame
mounted upon and pivoted to a flat plate forming part of the scale pan.
They are discharged by turning them around the pivot. A catch prevents the
receptacle being turned too far after each weighing.

Packages therewith, and for Settling or Shaking Down the
Material in Packages.
I WILLIAM THOMAS WHITEMAN of No 7-Staple Inn in the County of Middlesex
Patent Agent do hereby declare the nature of the said Invention for. " IMPROVE-
MACHINERY FOR WEIGHING SUBSTANCES AND FILLING PACKAGES
THEREWITH AND FOR SETTLING OR SHAKING DOWN THE MATERIAL IN PACKAGES

"
and in what manner the same is to be performed to be particularly described and
ascertained in and by the following statement:-
This invention relates to machines for filling packages or cartons of card board
paper or other material with equal weights of granular or pulverulent substances
such as bird seed hominy, oatmeal, coffee, corn, starch flour and the like, the
apparatus being of the class in which a gate controlling the flow of matter from a
hopper is operated by the tilting of the scale beam under the weight in or upon
the scale.
It comprises the following improvements hereinafter indicated upon the machine
described in the specification of Letters Patent granted to me and bearing date
the 31st day of October A.D. 1882 N° 5195 the object of the said improvements
being mainly to secure greater accuracy in the weighing under an ordinary
supervision although other objects are the simplification of the machine and the
adapting it, to fill different sizes and kinds of packages and to for use with a great
variety of substances.
First. It is found that a flat scale pan retains material which accidentally
escapes in small quantities until at length sufficient is collected to make an
appreciable difference in the weighing. To remedy this difficulty the horizontal
area of the package support part is made small or not materially larger than the
bottom of the package or carton which rests thereon and below this support is
placed a conical skirt which extends over the bearings of the scale pan below. If
any of the substance being weighed escape it falls upon the skirt and does not
adhere except in very small quantities. The skirt also by delivering it outside
prevents its lodging upon the scale beam.
Second. 2d In order that the scale may be the better adapted to filling different
sized packages the package support is made vertically adjustable so that it may be
brought nearer to or removed further from the delivery opening or spout.
Third. 3 The gauge plates for upholding the package in filling are mounted
upon rods projecting laterally from the package support and are made adjustable
thereon.
Fourth. 4. The latch for holding down the scale pan is provided with an
adjustable contact finger to be struck by the package when inserted. The object
of the adjustment is the better to accommodate different sized packages. Fifth. The
said latch is provided with a stop to limit the outward movement of the same
when the package is inserted and Sixth. The said lateh instead of being wholly
behind the scale pan as heretofore is placed partly in front and partly behind the
pivot being about on the middle line of the scale pan.

Seventh. The weighing scale is provided in addition to the ordinary adjustable
weights with a supplemental weight in the form of a nut adjustable on a screw rod.
Weight nuts have heretofore been used in the ordinary platform scales but the
particular construction and arrangement-(hereinafter fully set forth) whereby nut
weights are applied-to-small-automatie-seales is believed to be new and I therefore
make no separate claim to the application of such a weigh nut.
Eighth. 5 In order to render the scales independent of the centrifugal force
developed by the rotation of the revolving table balance weights are connected
with the scale beam on the opposite side of the fulcrum from the gate which
controls the supply. The weight nut before described is or may be arranged. to act
as a centrifugal balance weight.. Where the power is steady it is not necessary to
use the centrifugal weights as the centrifugal force being constant it can easily be
compensated for.
Ninth. 6 The scale bearings at the base of the rod which supports the supply
gate are protected by a shield which prevents the material weighed from lodging
thereon or therein.
<
Tenth. To prevent the moveable parts of the scale from rebounding when the
scale pan descends with its load which rebounding would be apt partly to open
the supply gate and thus cause.the delivery of an overweight into the packages the
brush at the front of the delivery opening is arranged to make contact with the
supply gate so as to give a slight friction sufficient to prevent a rebound of
the moving parts of the scale. The brush thus acts as a friction device which
comes into play at the end of the supply gate's movement, but I make no separate.
claim to this feature of my apparatus.
Eleventh. It is found desirable with some substances in order to prevent the
gate from wedging to use a brush at the back as well as at the front of the delivery
opening. This is not broadly new in automatic weighing scales and is only not
claimed herein in combination with the supply gate carried by a rod fixed at the
lower-end-in the scale beam.
Twelfth. 7 The delivery openings are provided with removable bushings of
frusto conical form this form being found in practice to be better than the flat or
plate bushing described in the specification of the aforesaid patent,
Thirteenth. 8 A hopper centrally placed over the axis of the revolving table
and provided with shoots radiating therefrom and descending towards the weighing
scales is found for substances of a ready flowing or granular nature to be a more
convenient form than the annular hopper of the previous patent. The delivery
openings are at the outer or lower ends of the shoots..
.
Fourteenth. To prevent the scale pan and scale beam from riding over their
bearings which they are apt to do when the knife edges enter the ordinary circular
openings in the supporting arms, the edges of the said openings are inclined at such
an angle that they will not ride upon the knife edges nor the knife edges upon
them. No separate claim is made to this feature of my apparatus.
Fifteenth.. 9 For filling packages with powdered substances like corn, starch or
flour means are provided for forcing or crowding the substances through the delivery
openings. The flow. of the. powdered substances through the delivery openings
which does not readily take place by the action of gravity alone on account of the
lightness of the material and its tendency to pack together is thus, assisted so that
a free delivery is obtained whenever the supply gates are withdrawn.
Heretofore it has been common to feed light material through a hopper opening
by means of a screw but so far as I am aware such a screw and hopper have not
been combined with an automatic weighing scale having a supply gate connected
with and operated by the scale.
It is found that the compacting of the powdered substance above the supply gate
does not interfere (the parts being properly proportioned) with the movement of
the gate but on the contrary that it has a beneficial effect in preventing the scale
from rebounding when the load carries down the scale pan and closes the gate.

page_text: "
It is not found necessary to use brushes with powdered substances. The annular
form of hopper is preferred the inclined blades being supported therein by a
stationary ring.
Sixteenth. For further assisting the powdered material through the delivery
openings there are raised pieces at each opening of the revolving annular hopper.
They as it were plough their way through the powder which is compacted by the
inclined blades and also by them held back so that it is not carried around so fast
as the hopper revolves.
.
Seventeenth. 10" These raised pieces are made adjustable so as to act as valves
to regulate the size of the delivery openings, but I make no general claim to the
use of a valve for this purpose. In this case the removable bushings are not used.
Eighteenth. 11 A stationary cam is provided for actuating a valve so as to
diminish the size of the delivery opening after the bulk of the charge has been
weighed. Thus both the rapidity of weighing due to the delivery of a large stream
and the accuracy due to the delivery of a small stream are measurably secured, as
has been heretofore done by other means in similar machines. This cam need not
be used.
Nineteenth. 12 For maintaining an uniform quantity of the powdered substance
in the revolving hopper the latter is supplied through a spout in which is a cut off for
regulating the flow, and the position of this cut off is controlled by a float which is
acted upon by the substance in the hopper. When the substance accumulates to a
sufficient depth it stops the flow and as the substance is drawn off it reopens the
valve and lets the hopper fill up again.
Twentieth. 13 For powdered substances a tapping apparatus or attachment is
provided for shaking down the substance in the package this apparatus having one
or more tappers or tapping arms arranged to strike the bottom of the package.
It is found that practically such tapping is much more effective in shaking down
the substance than when the blows are made on the sides of the package.
Twenty first. 14th The tapper is combined with a belt conveyor on which the
packages are placed after removal from the scales.
Twenty second. When the automatic scale is used without the cam and spindle
for upholding the rear end of the scale beam as in a small machine the beam
descends suddenly on removal of the package and it is apt to rebound and continue
in vibration for some time. The rebounding and vibration interfere with the.
delivery of the material and unless the scale comes to rest before the charge is
weighed out it interferes also with the accuracy of the weighing causing the gate to
close sooner or later than it ought.
To prevent this rebounding of the scale on opening the gate a stop is placed
under the weighted end of the scale beam so as to be struck by the same. It seems
to absorb the energy of the moving beam and prevent rebounding. Whatever the
explanation it enables the beam to come to rest much sooner than it otherwise
would. This device is old, and I make no separate claim thereto.
Twenty third. 15" In order to weigh rapidly it is desirable to deliver a larger
stream at first and when the bulk of the charge has been delivered to reduce the
stream so that the gate in closing shuts off a comparatively small stream.
Heretofore it has been proposed to have the scale or the scale beam effect such a
reduction in the flow of material by closing a valve and under the eighteenth
eleventh head of this description the use of a stationary cam acting upon a valve
for this purpose is set forth. In a hand machine, there is or would ordinarily be no
power to operate a cam.

E
The desired result is effected without the use of movable valves by combining
with a spout or hopper having a contracted orifice, a funnel or small reservoir
which is provided with a larger delivery opening to be closed by the supply gate
of the automatic weighing scale and into which the spout or mouth of the hopper
projects leaving a suitable space below the contracted orifice. When the supply 5
gate is closed the material descends through the orifice and fills the funnel or
reservoir to its own level. Then the material in the funnel or reservoir seals as it

page_text: were the orifice and prevents more material from passing out.
When the supply
gate is opened the material escapes rapidly and runs completely out of the funnel
or reservoir before the scale receives its charge. Then the delivery. continues from
the contracted orifice until the supply gate closes.
Twenty fourth. 16 It is desirable to be able to vary the quantity of material
in the funnel or reservoir in order to suit charges of different weights. This can be
done by adjusting the spout or hopper vertically so as to leave more or less distance
between its orifice and the delivery opening in the funnel or reservoir. It can also
be done by making the hopper revmovable so that it can be replaced by one which
descends lower or not so low in the funnel or reservoir and which may also have a
smaller or larger orifice. It is best effected by the use of removable bushings of
frusto conical form which fit in the hopper and which may be of various lengths
with various sized orifices. The smaller the quantity weighed the smaller should
be the orifice in order to secure an accurate weighing.
Twenty-fifth, 17th When granular material is fed through a long tube or spout
it is found that the pressure will affect the flow through the orifice and produce
inequalities in the weighings. To prevent this a plate or disk is supported at the
mouth of the tube or spout. It takes off the pressure due to the column of the
material. The material passes over the edges of the disk or plate. I make no
claim to the use of such a plate, except when employed as herein described.
Twenty-sixth. 18" In many cases it is not desirable or practicable to support
the packages or receptacle to contain the weighed material on the scale pan as for
example if the material is to be weighed independently of the package or when the
material is to be packed in bags. To meet such cases the following arrangements;
are used. The scale pan is provided with a receptacle which constitutes part of
the machine and is adapted to be discharged as well as to receive the material
weighed. In connection with such a scale pan a retaining latch is provided for
holding the scale pan depressed. To increase the rapidity of weighing, instead of
providing the scale pan with a single receptacle two or more of them are employed
and they are so constructed and arranged that one receptacle can be filling while
another is discharging. I am well aware that a scale pan for an automatic scale
adapted to discharge the material weighed is not new also that grain meters have
been made, with two grain receptacles which receive the grain from a common
spout and are adapted the one to discharge while the other is filling. The latch
arrangement to such a scale and also the particular construction and combination
of parts in and about the scale pan are believed to be new.
The receptacles are open at both ends and are connected with a spider frame
mounted upon and pivoted to a flat plate forming part of the scale pan.
They are discharged by turning them around the pivot. A catch prevents the
receptacle being turned too far after each weighing.

top or rotary table that is supported by and turns with the frame C. D is a column
bolted at the foot to the revolving frame C. E a hopper mounted on the upper end
of the column D. E the shoots descending obliquely from the hopper and G a
series of automatic weighing scales carried by the rotary table C¹..

page_text: The shoots E..consist each of a cylindrical tube which is upheld by an arm D¹
bolted to the column D and also by a boss 1 on the hopper. The upper end of the
shoot fits over the boss 1 and the lower bevilled end rests upon the top of the
arm D¹. A curved piece 2 fitting around the front of the shoot and screwed to the
arm D prevents the shoot from sliding forward or moving side wise.at the bottom,
A delivery: opening is made through the end of each arm D¹ and also through the
wedge shaped block 3 fixed to the underside of the arm.
The frusto conical bushing 4 fits in the opening and is supported by a flange at
the top. The bushing can be removed and replaced by one with a larger or smaller
bore by detaching the holding piece 2 and removing the shoot E.
The mouth pieces K are secured fast to the inclined bottom of the block 3.
There are brushes m m¹ respectively at front and back of each delivering opening
and at the sides thereof the depending. plates 1. The bristles of the front brush
preferably extend slightly below the lower edges of these plates in order to make
contact with supply. gate I¹ when it is moved forward. It thus acts as a friction
pad to prevent the scale rebounding. The edges of the gate I¹ and also of the
plates are bevilled. Under the mouth piece K is the small spout p. The gate 11
is fastened at the upper end of the arm I whose lower.end fits in a socket piece n
in the scale beam just behind the fulcrum. A set screw n¹ retains the arm in
place while allowing its adjustment. In the same socket piece n fits the bent rod 5
which is held in place by the set screw n¹. It is screw threaded at the outer end
and carries the nut weights 6 and also the centrifugal balance weights 7. The
latter are adjustable on the vertical part of the rod being held by a set.screw n¹!
and the former on the horizontal threaded part.
The weights are adjusted so that their centrifugal force due to the rotation of the
weighing scales with table C balances that of the arm I and gate I'¹. The nut
weights are adjusted to give precisely the balance desired in weighing.
Each weighing scale has a package support K¹ with gauge plates L L' on either
side. The gauge plates are supported by and are adjustable on the rods 15 that
project from the sides of the package support, see Fig. 2.
The package support is mounted on a vertically sliding carrier 37. In the
drawings the carrier slides. in the sleeve 8 which itself is adjustable vertically in
the collar 9 of the scale pan.. It may however slide. directly in the socket in the
scale pan. The former construction is preferable where a very large vertical
adjustment is desired.
Set screws retain the parts in the position to which they may be adjusted. The
scale pan is provided with the conical skirt 10 which extends over the bearings or
knife edges 16 by which the scale pan is supported in the beam. Any material
which may fall past the package does not collect on the scale pan but slides off and
is delivered clear of the bearings.
The knife edges 16 are fixed in the scale beam and project in the arms 17 which
support the scale pan. The front edges of these openings are straight (see Figure 5)
and present a steep inclination to the knife edge so that if pressure in placing the
package on the scale pan for example be applied tending to force back the scale
pan the pressure will be resisted or if the supporting arms ride on the knife edges
they will return to their former position so soon as the pressure is withdrawn.
With the same object the edge 19. of the openings in the supporting arms on which
the knife edges 20 rest are similarly inclined.
.
At the base of the arm I is a shield 21 which surrounds the arm and extends
over the adjacent part of the scale beam and also over the fulcrum. It is made
with sharply inclined sides as shown in Figure 1 for most materials but where
grains such as bird seed are to be weighed a flat form of shield may be adopted as
shown in Figure 6.
The latch N is pivoted at s to the collar 9 which it surrounds. The upper part
of the latch lies at the back of the scales and is provided with an adjustable
contact fingert which is struck by the package when the latter is placed on-the
package support. The lower part of the latch which engages the notch-12 in the

raises and lowers the spindles U at the proper time. The lifting device 2¹ on each
spindle U projects under the corresponding scale beam. Each spindle U carries a
ratchet wheel S for operating, tapping arms as described in the specification of the
aforesaid patent of 1882.-
These tapping arms need not be used if not desired.
The operation of the machine is as follows:-
The scales being all latched down so that all the gates I are closed and the
proper bushings 4 being placed and secured in the recesses therefor and the
package support K₁ and the gauge plates-L L' and contact finger t being properly
adjusted for the packages to be filled the scale weights being adjusted on the beam
and the nut weights on the screw rod, the hopper E is filled to the proper depth
The
with the material to be weighed and packed- and the machine is started.
table C being revolved rotated the scales are successively made to pass the
attendant who is stationed in front of the cam X. As they come opposite him he
places a carton or empty package M between the gauge plates L L¹ until stopped
by the contact of stop 11 with skirt 10. He is careful to place the side of the
carton which has no flap adjacent to the gauge plate L. This makes the opposite
side which has the longest flap, face the mouth of the spout p. This mouth has
been made at one side in order to deliver the material away from the open or
flapless side.
The carton or package as it is inserted strikes and pushes back the contact
piece t vibrating the latch N and releasing it from the notch 12. The scale-pan
with its carton or package does not however rise immediately because the
spindle U is still raised by the cam X and the device z¹ upholds the scale beam
keeping the gate I¹ closed. As the spindle U is gradually allowed to descend the
gate I opens and allows the material to descend through the spout p into the
carton or package. The descent of the spindle U brings the pinion x into contact
with the friction gear W and the said spindle and the ratchet wheel S cominences
to revolve. If the tapping arms not shown are in action they are vibrated by the
wheel S and tap on the sides of the carton so as to shake down the material
delivered thereinto. As soon as the proper quantity of material has passed into
the carton or package the scale pan is depressed tilting forwards the arm I and
gate I and stopping the delivery of material. After the delivery ceases the
spindle U is again raised by the cam X when the full package is removed and a
fresh one put in its place. As soon as the full package is removed the latch N
immediately drops into engagement with the notch 12 and if the attendant should
neglect to insert an empty carton it would continue to hold down the scale and
keep closed the gate (as shown at the right of Figure 1) until released by the
insertion of a fresh carton or package. Should the attendant not remove a full
package its weight would of course keep the gate I¹ closed.
One of the weighing scales could be provided with its own hopper and be used
as a complete small machine its capacity being of course much less than that of the
machine shown.
The machine shown in Figures 7 to 10 is similar to that just described with
reference to Figures 1 to 6 except in the particulars mentioned below.
E is an annular hopper fixed to and supported by the hollow column D and F a
spider frame attached to the stationary shaft B. Motion is imparted to .the
frame C and table in the direction of the arrow through the bevil gears e and f
and the horizontal shaft H that is journaled in bearings in the bracket and is
driven by a belt running on the pulley h..
g

page_text: Upon the table are placed weighing scales G say four in number although there
may be less or more. In the bottom of the hopper there are as many openings as
there are scales on the table. The scales are the same as before described with
reference to Figures 1 to 6.
Under each of the openings in the bottom of the hopper is a mouth piece K.-
Its lower edges lie in a plane inclined to the horizontal to the same degree as the
gate when closed. This supply gate works out of contact with but in close
proximity to the said edges.
Above each delivery opening in the hopper is placed an adjustable valve 50 for
regulating the size of opening and thus controlling the delivery. It is attached to
the lower end of the carrier 51 pivoted at 52 to the inner wall of the hopper. A
spring 53 (shown as spiral tension spring) tends to withdraw the valve so as to
uncover the opening but its action is resisted by the screw stop 54. By adjusting
the screw in the proper position the opening can be made larger or smaller as
desired. In connection with these valves a cam 55 is or may be employed. It
is fixed to the spider frame F and is so arranged that as the valve carriers 51 pass.
under it they are turned in the direction nearly, to close the valve leaving but a
small opening. The object of this is to combine quickness with accuracy of
weighing. The same stop 54 is so adjusted that almost the desired weight will
have passed through the opening by the time the valve carrier reaches the cam.
During this time the flow may be comparatively rapid.
When the upper end of the valve carrier strikes the cam the valve is advanced
and the material flows from the hopper in a fine stream which favors accuracy in
weighing. It is not however necessary to use the cam 55 for the valves can be
adjusted so that the stream from the hopper is always small enough to secure
accurate weighing.
The valves 50 are supported above the bottom of the hopper in order to catch
the material and force it into the opening. The better to accomplish this purpose
the edge of the mouth piece K which projects above the bottom of the hopper is
cut away at 56 and the front of the valve which is made thick is bevilled (see
Figure 9).
"
It is evident that a piece not adjustable to act as a valve could be used for this
purpose of forcing the material into the opening. It is preferred however to make
the valve perform the double function. The valves or raised pieces 50 are assisted
in their work of forcing the material through the openings by the inclined blades 57
which are set at intervals on the stationary curved rod 58. This curved rod is
attached to and supported by the pendent rods 59 from the spider frame F.
As the hopper revolves it carries the substance therein under the inclined blades
which compact the substance at the bottom of the hopper and also force it into
the delivery openings. At the same time they hold back the substance or material
so that it does not move around quite so fast as the hopper. Consequently the
valves or raised pieces plough their way (so to speak) through the compacted
material and the result is a steady and practically uniform delivery of the material
from the hopper.
The material is fed into the hopper from the bin 60 through the spout 61. In
the bin 60 is a stirrer 62 which is kept in continual rotation by a belt or pulley 63..
At the bottom of the bin is the cut off 64 pivoted at 65 to the spout and controlled
by the float 66. This float consists of a metal plate which preferably has the edges
bent down as shown. As the material is carried under the plate it holds it up and
thus regulates the position of the cut off. When sufficient material has collected
in the hopper it stops entirely the flow from the bin.
The tapping apparatus or attachment for shaking down the material in the
packages after it has been weighed into them is placed at the front of the machine.
It consists of a supporting frame 160 a conveyor belt 161 a tapper or tapping
arm 162 arranged under the.belt the operating mechanism and the side plates.163
for retaining the packages in place on the belt. The conveyor belt 161 is revolved
at a speed corresponding with that of the table C₁ so that it will hold the packages

page_text: as fast as they are filled with the material. It is driven from the pulley 164 on
the shaft H of the machine through the belt 165 pulley 166 on shaft 67 worm 68
on said shaft and larger worm gear 69 on the journal of pulley 70 at the right end
(Figure 7) of the frame. The belt travels over and when loaded with packages
rests upon the side pieces 71 of the frame.
Between the side pieces 71 is the tapper 162 mounted on the horizontal arm of
bell crank lever 620 supported and turning upon the pin or rod 72. It is vibrated
by the conjoint action of a ratchet wheel 73 and a spring 74 (shown as a spiral
tension spring) fastened at one end to the short arm of lever 620 and at the other
to a pin on the frame. The ratchet teeth withdraw the tapper against the action
of the spring and when they release it the spring throws it up so that it gives a
smart blow directly upon the underside of the belt and indirectly (that is through
the belt) upon the bottom of the package.
The side plates 163 are supported upon the studs or pins 75 which project
laterally from the side pieces 71 by arms 76 whose hubs fit over the said studs or
pins and are held thereon by set screws so that the said plates are adjustable
towards and away from each other. The packages as they are taken from the
weighing scales are placed upright on said conveyor belt and as they pass over the
tapper have their contents shaken down. The conveyor belt can be extended to
any distance to the workmen whose duty it is to close and seal up the packages.
The belt passes or may pass over the top of a table at which the workmen are seated.
The operation of the machine or apparatus is as follows:-
The scales being all latched down so that all the gates I¹ are closed and the
valves 50 package supports K gauge plates L L' and the scale weights being
properly adjusted the hopper E is filled to the proper depth say one third with the
material to be weighed and packed the bin is also filled and the machine is started:
The table C being revolved the scales are successively made to pass the attendant
who is stationed in front of the cam X. As they come opposite him he places a
carton or empty package M between the gauge plates L L¹ until he presses back
and releases the latch N. The scale pan with its carton or package does not
however rise immediately because the rod U is still raised by the cam X and tho
device upholds the scale beam keeping the gate I¹ closed: As the rod U is
gradually allowed to descend the gate I opens and allows the material to descend
into the carton or package.
•
The powdered material in the hopper is forced through the delivery openings in
a constant stream by the combined action of the inclined blades 57 and valves or
raised pieces 50. If the cam 55 be used the valves 50 are nearly closed as the
scales come under it so that a fine stream is delivered. This change takes place
after the bulk of the charge has been delivered into the package. When the full
charge has been received the scale pan descends closing the supply gate I¹ and
stopping the delivery.
After the delivery ceases the rod U' is again raised by the cam X when the full
package is removed and a fresh one put in its place. As soon as the full package
is removed the latch N immediately drops into engagement with the notch 12 and
if the attendant should neglect to insert an empty carton it would continue to
hold down the scale and keep closed the gate until released by the insertion of a
fresh package. Should the attendant not remove the full package its weight
would of course keep the gate I¹ closed.
The packages as they are removed from the scale are placed on the conveyor
belt,161 and by it carried above the tapper 162 which shakes down the contents
and thence to the workmen who seal the packages. If it be not desired to use the
tapper it can be thrown out of action by releasing the tension of the retractile
springs 74.
Referring to Figures 11 to 14 the scale beam 100 is supported on knife edges 101
which enter V-shaped openings 102 in the machine frame. The scale pan is
supported at the front (left band Figure 11) end of the beam on knife edges 103
fixed in the beam which enter V-shaped openings in the arms 104 attached to or

page_text: making part of the scale pan. The upright position of the scale pan is maintained
in the usual way by a link in the base of the frame. At the top of the scale pan
is a flat plate 105. On this plate are supported the receptacles 106 (three are
shown) for receiving the material to be weighed. They are open at both ends.
Their lower ends rest upon the plate 105 which is ground or turned off smooth
and forms. the bottom to the receptacles. The receptacles are attached to a spider
frame 107. At equal distances from the centre said spider frame has a central hub
and is pivoted to the plate by a screw 108 passing through said hub and tapped
into the plate. There is a sleeve 109 surrounding the shank of the screw upon
which the hub turns. At each receptacle is a pin 132 and on the plate 105 is a
spring stop 133 which is in the path of the pins 132 but can be depressed to remove
it out of the way when it is desired to turn the receptacles and the spider frame.
At the front of the scale under the plate 105 which is perforated is a small
spout 110 supported by upright rods 111 fixed at their lower ends to the machine
frame. There is also a short tube 150 fastened to the plate 105. Above the scale
pan is the funnel or reservoir 112 supported. by the bracket making part of the
machine frame having a delivery opening in the bottom. The hole in plate 105
and the delivery opening in the funnel or reservoir 112 are so placed that when
one receptacle 106 is over the hole the next one is under the delivery opening.
The mouth piece is fastened to the bottom of the funnel or reservoir 112. It has
a brush 114 and 115 at front and back respectively and metallic side walls 116.
The bristles of front brush 114 project slightly below the edges of the side walls.
The supply gate 117 works below the. mouth being fastened to the upper end of
the arm 118 whose lower end .fits in the socket pieces 119 fastened to the scale.
beam and is there held by a set screw. The supply gate is so adjusted that as it
passes under the front brush 114 it makes contact with the same. The lower edge
of the side walls 116 and the front of the supply gate are bevilled.
Above the funnel or reservoir 112 is the hopper 120 removably supported by
the arms 121 fixed to the hopper and resting upon the edge of the funnel or
reservoir. A spout 122 conducts the material to be weighed into the hopper from
an elevated bin. At the mouth of the hopper is a removable bushing 125. Below
the spout is the disk or plate 123 which is upheld by the arms 124 resting against
the inside of the hopper. To fill small packages. a longer bushing with a smaller
orifice is used for larger packages a shorter one with larger orifice.
The latch 126 is placed below the scale, pan. It is pivoted at 127 to the scale
frame and its upper end is adapted to engage the front end of the scale beam when
the scale, pan descends and the latch is not held back. A wire 128 is attached to:
and projects forward from the latch. Its inner end is clamped beneath the
washer 129 which is held by a screw tapped into the latch. It is therefore
adjustable. When the package is placed around the spout 110 the edge thereof
strikes the wire and lifts it realeasing the latch and allowing the scale pan to rise.
On the rods 111 on either side of the spout 110 are the hooks 130 for supporting
a bag with its mouth extended. They are so arranged that when the mouth of
the bag is placed over them the edge of the bag holds the latch wire 128 in its
raised position.
Under the weighted or rear end of the beam is placed a stop 131 so arranged
that the beam makes contact with the upper end thereof. when the scale pan has
risen to its full height. As shown the beam is provided in addition to the
adjustable weight with a weight rigidly fastened at the end of the beam.
need not be used or it may be replaced by a hanging dish to receive removable
weights as common in weighing scales.
The operation of the machine is as follows:-
This
Assuming the scale pan to be latched down and the supply gate closed the
granular material descends through the spout 122 and fills the hopper 120 to or
nearly to the lower end of the spout and the reservoir or funnel 112 to or nearly
to the lower end of the bushing 125 or if no bushing is used to the lower end of
the hopper 120,

page_text: If the receptacle 106 which at the time is under the reservoir or funnel 112 be
empty the attendant trips with his hand the latch 126 whereupon the weighted
end of the scale beam descends (and at the end of its movement, strikes the
stop 131) the scale pan rises and the supply gate 117 is withdrawn. The tendency
of the scale to rebound is diminished by the action of the stop 131 and the beam
now comes to rest. As soon as the supply gate is opened the material in the
funnel or reservoir 112 runs rapidly through the delivery opening into the
receptacle 106. until the funnel or reservoir 112 is empty. As the amount (in
consequence of regulation made to that end) is insufficient to bear down the scale
pan the material continues to flow but in a smaller stream through the-smaller
orifice of the bushing 125 or of the hopper 120 if no bushing be used. The level
of the material, in the hopper 120 is maintained constant by the flow from the
spout 122 the pressure of the column in said spout being taken off by the disc or
plate 123.
When the receptacle 106 has received its charge the scale pan descends and is
automatically latched down. As the supply gate 117 closes it makes a light
contact with the front brush 114 and the slight friction prevents any tendency of
the scale to rebound.
..
The attendant now places the package under the spout 110 and raises it until
the upper edge strikes and lifts the wire 128 tripping the latch 126 and releasing
the scale.
If the package be a bag the edges are caught over the hooks 130 in
which position the edge of the bag holds up the wire 128.
Although the latch is released the scale does not move because the charge is
still in the receptacle 106. The attendant takes hold of the pin 132 and with the
thuinb depressing the stop 133 turns the spider frame 107 so as to bring the
charged receptacle over the opening in the plate-105 and an empty one under
the funnel or reservoir 112. The spider frame is stopped at the proper place by
the next pin 132 striking the stop 133 which has been released as soon as the
former pin was disengaged.
The charge in the receptacle which has been brought over the hole in the
plate 105 runs through the spout 110 with the package placed below it. So soon
as the discharge begins the scale pan rises the supply gate is withdrawn and the.
delivery into the succeeding receptacle (now under the funnel or reservoir) com-
mences. Thus while one receptacle is discharging another is filling. The filled"
package would ordinarily be removed and an empty one inserted by the time the
receptacle received its charge.
It is evident that modifications could be made in the details without departing
from the spirit of the invention and that parts of the invention could be used
separately.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed I declare that what
I claim is I make no claim to any of the subordinate integers of my invention,
except when used in machines of the kind to which this specification and my said

I WILLIAM THOMAS WHITEMAN of No 7 Staple Inn in the County of
Middlesex Patent Agent do hereby declare the nature of the said invention for
"IMPROVEMENTS IN MACHINERY FOR WEIGHING SUBSTANCES AND FILLING PACKAGES
THEREWITH AND FOR SETTLING OR SHAKING DOWN THE MATERIAL IN PACKAGES
to be as follows:-
"
This invention has reference more particularly to machines for filling packages
or cartons of card board paper and other material with equal weights of granular
substances such as bird seed hominy oatmeal coffee and the like or of powdered
substances such as corn starch flour and the like and also to machinery for settling
or shaking down the matters in the packages but is applicable in whole or in part
to other machinery.
It is mainly designed as a modification of and improvement upon the machine
described in the specification of Letters Patent granted to me and bearing date the
31st day of October A.D. 1882. No 5195 although the present improvements or
some of them are or may be applicable to other machines.
In the patented machine a number (four) of weighing scales are carried by a
revolving table. The pan or plate of each scale is adapted to receive and support &
carton or package. A hopper is supported above the scales and revolves with the
table. It has a series of openings one over each scale pan or or scale plate so that the
material in the hopper may flow through the opening into the carton or package on

page_text: :
the scale pan or plate. At each delivery-opening there is a gate. controlled by the
corresponding weighing scale so that when the pan or plate thereof is depressed the
gate is advanced to close the opening and cut off the delivery of material to the
package and when the scale pan or scale plate is raised the gate is withdrawn to
uncover the opening and allow the delivery to recommence.
A latch is provided for holding down the scale-pan that it may not rise and
uncover the delivery opening when relieved of the weight of a full carton or
package until a new one is placed on the scale-pan. This latch is arranged to be
operated automatically by contact with the package. There are also sliding spindles.
one for each weighing scale which support the scale beam with the scale pan
depressed and supply gate closed during the removal of a full package and the
insertion of an empty one.
Tapping apparatus (one for each weighing scale) are provided for tapping the
packages on the scale pan when desired. They are operated from the aforesaid
spindles which are revolved by contact with a friction wheel.
In the said specification it is also pointed out that a single weighing scale which
does not rotate can be used in connection with a suitable hopper where a small
machine is desired.
C.
The object of the present invention is mainly to secure greater accuracy in the
weighing by an ordinary supervision although other objects are the simplification
of the machine and the adapting it to fill different sized packages and to use with
different substances and the perfecting of the tapping apparatus.
It is found that a flat scale-pan retains material which accidentally escapes in small
quantities until at length sufficient is collected to make an appreciable difference in
the weighing. To remedy this difficulty the horizontal area of the package support
part is made. small or not materially larger than the bottom of the package or
carton which rests thereon and. below this support is a conical skirt which extends
over the bearings of the scale pan below. If any of the substance, being weighed
escape it falls upon the skirt. and does not adhere except in very small quantities.
The skirt also by delivering it outside prevents its lodging upon the scale beam.
In order that the scale may be the better adapted to filling different sized packages
the package support is made vertically adjustable so that it may be brought nearer
to or removed farther frem the delivery opening or spout..
The gauge plates for upholding the package in filling are mounted upon rods
projecting laterally from the package support, and are made adjustable thereon.
The latch for holding down the scale-pan is provided with an adjustable contact
finger to be struck by the package when inserted. The object of the adjustment is
the better to accommodate different sized packages.
The latch is provided with a stop to limit the outward movement or movement
of the same when the package is inserted.
The latch instead of being wholly behind the scale-pan as heretofore is placed
partly in front and partly behind the pivot being about on the middle line of the
scale pan.
The weighing scale is provided in addition to the ordinary adjustable weights
with a supplemental weight in the form of a nut adjustable on a screw rod
Weight nuts have heretofore been used in the ordinary platform scales but the
particular construction and arrangement (hereinafter fully set forth) whereby nut
weights are applied to small automatic scales is believed to be new.
In order to render the scales independent of the centrifugal force developed by
the rotation of the revolving table balance weights are connected with the scale-
beams on the opposite side of the fulcrum from the gate which controls the supply.
The weight nut before described is or may be arranged to act as a centrifugal
balance weight. When the power is steady it is not necessary to use the centrifugal
weights as the centrifugal force being constant it can easily be compensated for.
The scale bearings at the base of the rod which supports the supply gate are
protected by a shield which prevents the material weighed from lodging thereon or
therein.

To prevent the moveable parts of the scale from rebounding when the scale pan
descends with its load which rebounding would be apt partly, to open the supply
gate and thus deliver an over weight into the package the brush at the front of the
delivery opening is arranged to make contact with the supply gate so as give
slight friction sufficient to prevent a rebound of the moving parts of the scale. The
brush thus acts as a friction device which comes into play at the end of the supply,
gate's movement.
It is found desirable with some substances in order to prevent the gate from
wedging to use a brush at the back as well as at the front of the delivery opening.
This is not broadlý new in automatic weighing scales and is only claimed herein in
combination with the supply, gate carried by a rod fixed at the lower end in the
scale-beam.
The delivery openings are provided with removeable bushings of frusto conical
form this form being found in practice to be better than the flat or plate bushing
described in the specification of the aforesaid Patent.
A hopper centrally placed over the axis of the revolving table and provided with
shoots radiating therefrom and descending towards the weighing scale is found for
substances of a ready flowing or granular nature to be a more convenient form than
the annular hopper of the patent. The delivery openings are at the outer or lower
ends of the shoots.
To prevent the scale pan and scale beam from sliding over their bearings which
they are apt to do when the knife edges enter the ordinary circular openings in the
supporting arms the edges of the said openings are inclined at such an angle that
they will not ride upon the knife edges nor the knife edges upon them.
For filling packages of card board paper and other materials with equal weights
of powdered substances such as corn starch flour and the like inclined blades are
provided for forcing or crowding the substance in the hopper into the said delivery
opening or openings.
By this means the flow of the powdered substance through the delivery openings
which does not readily take place by the action of gravity alone on account of the
lightness of the material and its tendency to pack together is assisted so that a
free delivery is obtained whenever the supply gates are withdrawn.
Heretofore it has been common to feed light material through a hopper, opening
by means of a screw but a screw hopper has not been combined with an automatio
weighing scale having a supply gate connected with and operated by the scale.
It is found that the compacting of the powdered substance above the supply,
gate does not interfere (the parts being properly proportioned) with the movements
of the gate but on the contrary that it has a beneficial effect in preventing the
scale from rebounding when the load comes down the scale pan and closes the
gate.
It is not found necessary to use brushes with powdered substances. The
annular form of hopper is preferred the inclined blades being supported therein by
a stationary ring.
For further assisting the powdered material through the delivery openings there
are raised pieces at each opening of the revolving annular hopper. They as it were
plough their way through the powder which is compacted by the inclined blades
and also by them held back so that it is not carried around so fast as the hopper;
revolves.
These raised pieces are made adjustable so as to act as valves to regulate the size
of the delivery openings. In this case the removeable bushings are not used.
A cam is provided for actuating a valve so as to diminish the size of the delivery
opening after the bulk of the charge has been weighed. Thus both the rapidity,
of weighing due to the delivery of a large stream and the accuracy due to the
delivery of a small stream are measurably secured. This cam need not be used.
For maintaining an uniform quantity of the powdered substance in the hopper,
the latter is supplied through a spout in which is a cut off for regulating the flow,
and the position of this cut off is controlled by a float which is acted upon by the

page_text: substance in the hopper. When the substance accumulates to a sufficient depth it
stops the flow and as the substance is drawn off it reopens the valve and lets the
hopper fill up again.
An improved tapping apparatus or attachment for shaking down the substance in
the package is used the said apparatus or attachment consisting of one or more
tappers or tapping arms arranged to strike the bottom of the package.
It is found that practically such tapping is much more effective in shaking down
the substance when the blows are made on the sides of the package.
The tapper is combined with a belt conveyor on which the packages are placed
after removal from the scales.
When this scale is used without the cam and spindle as in a small machine the
beam descends suddenly and with the ordinary scales it is apt to rebound and con-
tinue in vibration for some time. The rebounding and vibration interferes with
the delivery of the material and unless the scale come to rest before the charge is
weighed out it interferes also with the accuracy of the weighing causing the gate
to close sooner or later than it ought. To prevent this rebounding of the scale on
opening the gate a stop is placed under the weighted end of the scale beam so as to
be struck by the same. It seems to absorb the energy of the moving beam and
prevent rebounding. Whatever the explanation it causes the beam to come to rest
much sooner than it otherwise would.
In order to weigh rapidly it is desirable to deliver a larger stream at first and
when the bulk of the charge has been delivered to reduce the stream so that the
gate in closing shuts off a comparatively small stream. Heretofore it has been
proposed to cause the scale to effect such a reduction in the flow of material by
closing a valve and the use of a cam acting upon a valve for this purpose is herein-
before set forth. In a hand machine there is no power to operate a cam.
The desired result is effected according to this invention without the use of
moveable valves by combining with a spout or hopper having a contracted orifice a
funnel or small reservoir which is provided with a larger delivery opening to be
closed by the supply gate of the automatic weighing scale and into which the
spout or mouth of the hopper projects leaving a suitable space below the con-
tracted orifice. When the supply gate is closed the material descends through the
órifice and fills the funnel or reservoir to its own level. Then the material in the
funnel or reservoir seals as it were the orifice and prevents more material from
passing out When the supply gate is opened the material escapes rapidly and runs
completely out of the funnel or reservoir before the scale receives its charge.
Then the delivery continues from the contracted orifice until the supply gate
closes.
It is desirable to be able to vary the quantity of material in the funnel or
reservoir in order to suit charges of different weights. This can be done by
adjusting the spout or hopper vertically so as to leave more or less distance
between its orifice and the delivery opening in the funnel or reservoir It can
also be done by making the hopper removeable so that it can be replaced by one
which descends lower or not so low in the funnel or reservoir and which may also
have a smaller or a larger orifice. It is best effected by the use of removeable
bushings of frusto conical form which fit in the hopper and which may be of various
lengths with various sized orifices. The smaller the quantity weighed the smaller
should be the orifice in order to secure an accurate weighing.
When granular material is fed through a long tube or spout it is found that the
pressure will affect the flow through the orifice and produce inequalities in the
weighings. To prevent this a plate or disc is supported at the mouth of the tube
or spout It takes off the pressure due to the column of the material. The material
passes over the edges of the disc or plate.
In many cases it is not desirable or practicable to support the packages or
receptacle to contain the material weighed on the scale pan as for example if
the material is to be weighed independently of the package or when the material
is to be packed in bags. To meet such cases the following arrangements are used,

page_text: The scale pan is provided with a receptacle which constitutes part of the machine
and is adapted to be discharged as well as receive the material weighed.
In con-
nection with such a scale pan a retaining latch is provided for holding the scale
pan depressed. To increase the rapidity of weighing instead of providing the scale
pan with a single receptacle two or more of them are employed and they are so
constructed and arranged that one receptacle can be filling while another is
discharging. A scale pan for an automatic scale adapted to discharge the material
weighed is not new and grain meters have been made with two grain receptacles
which receive the grain from a common spout and are adapted the one to discharge
while the other is filling The latch arrangement to such a scale and also the
particular construction and combination of parts in and about the scale pan are
however believed to be new.
The receptacles are open at both ends and are connected with a spider frame
mounted upon and pivoted to a flat plate forming part of the scale pan.
They are discharged by turning them around the pivot. A catch prevents the
receptacle being turned too far after each weighing.

"
and in what manner the same is to be performed to be particularly described and
ascertained in and by the following statement:-*
This invention relates to machines for filling packages or cartons of card board
paper or other material with equal weights of granular or pulverulent substances
such as bird seed hominy oatmeal coffee corn starch flour and the like.
It comprises the following improvements upon the machine described in the
specification of Letters Patent granted to me and bearing date the 31st day of
October A.D. 1882 the object of the said improvements being mainly to secure
greater accuracy in the weighing under an ordinary supervision although other
objects are the simplification of the machine and the adapting it to fill different
sizes and kinds of packages and to use with a great variety of substances.
First. It is found that a flat scale pan retains material which accidentally escapes
in small quantities until at length sufficient is collected to make an appreciable
difference in the weighing. To remedy this difficulty the horizontal area of the
package support part is made small or not materially larger than the bottom of
the package or carton which rests thereon and below this support is placed a conical
skirt which extends over the bearings of the scale pan below. If any of the
substance being weighed escape it falls upon the skirt and does not adhere except
in very small quantities. The skirt also by delivering it outside prevents its
lodging upon the scale beam.
Second. In order that the scale may be the better adapted to filling different
sized packages the package support is made vertically adjustable so that it may be
brought nearer to or removed further from the delivery opening or spout.
Third. The gauge plates for upholding the package in filling are mounted upon
rods projecting laterally from the package support and are made adjustable thereon.
Fourth. The latch for holding down the scale pan is provided with an adjustable
contact finger to be struck by the package when inserted. The object of the
adjustment is the better to accommodate different sized packages.
Fifth. The said latch is provided with a stop to limit the outward movement of
the same when the package is inserted.
Sixth. The said latch instead of being wholly behind the scale pan as beretofore
is placed partly in front and partly behind the pivot being about on the middle line
of the scale pan.
Seventh. The weighing scale is provided in addition to the ordinary adjustable
weights with a supplemental weight in the form of a nut adjustable on a screw rod.

Eighth. In order to render the scales independent of the centrifugal force

Ninth. The scale bearings at the base of the rod which supports the supply. gate
are protected by a shield which prevents the material weighed from lodging thereon
or therein.
་
Tenth. To prevent the moveable parts of the scale from rebounding when the
scale pan descends with its load which rebounding would be apt partly to open
the supply gate and thus cause the delivery of an overweight into the packages the
brush at the front of the delivery opening is arranged to make contact with the

the moving parts of the scale. The brush thus acts as a friction device. which
comes into play at the end of the supply gate's movement.

from wedging to use a brush at the back as well as at the front of the delivery
opening. This is not broadly new in automatic weighing scales and is only claimed
herein in combination with the supply gate carried by a rod fixed at the lower end

Twelfth. The delivery openings are provided with removable bushings of frusto
conical form this form being found in practice to be better than the flat or plate
bushing described in the specification of the aforesaid patent.
Thirteenth. A hopper centrally placed over the axis of the revolving table and
provided with shoots radiating therefrom and descending towards the weighing
scales is found for substances of a ready flowing or granular nature to be a more
convenient form than the annular hopper of the patent. The delivery openings are
at the outer or lower ends of the shoots.
.T
Fourteenth. To prevent the scale pan and scale beam from. riding over their
bearings which they are apt to do when the knife edges enter the ordinary circular
openings in the supporting arms the edges of the said openings are inclined at such
an angle that they will not ride upon the knife edges nor the knife edges upon
them..
Fifteenth. For filling packages with powdered substances like corn starch or
flour means are provided for forcing or crowding the substances through the delivery
openings. The flow of the powdered substances through the delivery openings
which does not readily take place by the action of gravity alone on account of the
lightness of the material and its tendency to pack together is thus assisted so that
a free delivery is obtained whenever the supply gates are withdrawn.
Heretofore it has been common to feed light material-through a hopper opening

does not interfere (the parts being properly proportioned) with the movement of
the gate but on the contrary that it has a beneficial effect in preventing the scale
from rebounding when the load carries down the scale pan and closes the gate.
It is not found necessary to use brushes with powdered substances. The annular
form of hopper is preferred the inclined blades being supported therein by a.
stationary ring.
Sixteenth. For further assisting the powdered material through the delivery
openings there are raised pieces at each opening of the revolving annular hopper.

page_text: They as it were plough their way throug the powder which is compacted by the
inclined blades and also by them held back so that it is not carried around so fast

Seventeenth. These raised pieces are made adjustable so as to act as valves to
regulate the size of the delivery openings. In this case the removable bushings are
not used.
.
Eighteenth. A cam is provided for actuating a valve so as to diminish the size
of the delivery opening after the bulk of the charge has been weighed. Thus both
the rapidity of weighing due to the delivery of a large stream and the accuracy due
to the delivery of a small stream are measurably secured. This cam need not be
used.
Nineteenth. For maintaining an uniform quantity of the powdered substance in

or more tappers or tapping arms arranged to strike the bottom of the package.
It is found that practically such tapping is much more effective in shaking down
the substance than when the blows are made on the sides of the package.
Twenty-first. The tapper is combined with a belt conveyor on which the packages
.are placed after removal from the scales.
Twenty-second. When the automatio scale is used without the cam and spindle
for upholding the rear end of the scale beam as in a small machine the beam
descends suddenly on removal of the package and it is apt to rebound and continue
in vibration for some time. The rebounding and vibration interfere with the
delivery of the material and unless the scale comes to rest before. the charge is
weighed out it interferes also with the accuracy of the weighing causing the gate to
close sooner or later than it ought.
To prevent this rebounding of the scale on opening the gate a stop is placed
under the weighted end of the scale beam so as to be struck by the same.
It seems
'to absorb the energy of the moving beam and prevent rebounding. Whatever the
explanation it enables the beam to come to rest much sooner that it otherwise
would.
•
Twenty-third. In order to weigh rapidly it is desirable to deliver a larger stream
at first and when the bulk of the charge has been delivered to reduce the stream so
that the gate in closing shuts off a comparatively small stream.
Heretofore it has been proposed to have the scale effect such a reduction in the
flow of material by closing a valve and under the eighteenth head of this description
the use of a cam acting upon a valve for this purpose is set forth. In a hand
machine there is or would ordinarily be no power to operate a cam.
The desired result is effected without the use of movable valves by combining
with a spout or hopper having a contracted orifice a funnel-or small reservoir
which is provided with a larger delivery opening to be closed by the supply gate
of the automatic weighing scale and into which the spout or mouth of the hopper
projects leaving a suitable space below the contracted orifice. When the supply
gate is closed the material descends through the orifice and fills the funnel or
reservoir to its own level. Then the material in the funnel or reservoir seals as it
were the orifice and prevents more material from passing out. When the supply
gate is opened the material escapes rapidly and runs completely out of the funnel
or reservoir before the scale receives its charge. Then the delivery continues from
the contracted orifice until the supply gate closes.
Twenty-fourth. It is desirable to be able to vary the quantity of material in
the funnel or reservoir in order to suit charges of different weights. This can be
done by adjusting the spout or hopper vertically so as to leave more or less distance

page_text: between its orifice and the delivery opening in the funnel or réservoir. It can also
be done by making the hopper revovable so that it can be replaced by one which
descends lower or not so low in the funnel or reservoir and which may also have a
smaller or larger orifice. It is best effected by the use of removable bushings of
frusto conical form which fit in the hopper and which may be of various lengths
with various sized orifices. The smaller the quantity weighed the smaller should
be the orifice in order to secure an accurate weighing.
Twenty-fifth. When granular material is fed through a long tube or spout it is
found that the pressure will affect the flow through the orifice and produce
inequalities in the weighings. To prevent this a plate or disk is supported at the
mouth of the tube or spout. It takes off the pressure due to the column of the
material. The material passes over the edges of the disk or plate.
Twenty-sixth. In many cases it is not desirable or practicable to support the
packages or receptacle to contain the weighed material on the scale pan as for
example if the material is to be weighed independently of the package or when the
material is to be packed in bags. To meet such cases the following arrangements
are used. The scale pan is provided with a receptacle which constitutes part of
the machine and is adapted to be discharged as well as to receive the material
weighed. In connection with such a scale pan a retaining latch is provided for
holding the scale pan depressed. To increase the rapidity of weighing instead of
providing the scale pan with a single receptacle two or more of them are employed
and they are so constructed and arranged that one receptacle can be filling while
another is discharging. I am well aware that a scale pan for an automatic scale
adapted to discharge the material weighed is not new also that grain meters have
been made with two grain receptacles which receive the grain from a common
spout and are adapted the one to discharge while the other is filling. The latch
arrangement to such a scale and also the particular construction and combination
of parts in and about the scale pan are believed to be new.
The receptacles are open at both ends and are connected with a spider frame
mounted upon and pivoted to a flat plate forming part of the scale pan.
They are discharged by turning them around the pivot. A catch prevents the
receptacle being turned too far after each weighing.

paper packages or bags of various materials with substances such as coffee or lead
shot. Figure 11 being a vertical section parallel to the scale beam Figure 12 a

Referring to Figures 1 to 6 A is the base of the machine hereinafter called the
pedestal Ca frame supported and turning upon the top of the pedestal C¹ a marble
top or rotary table that is supported by and turns with the frame C D is a column
bolted at the foot to the revolving frame C E a hopper mounted on the upper end
of the column D. E¹ the shoots descending obliquely from the hopper and Ga
series of automatic weighing scales carried by the rotary table C¹.
The shoots E consist each of a cylindrical tube which is upheld by an arm D¹
bolted to the column D and also by a boss 1 on the hopper. The upper end of the
shoot fits over the boss 1 and the lower bevilled end rests upon the top of the
arm D¹. A curved piece 2 fitting around the front of the shoot and screwed to the
arm D¹ prevents the shoot from sliding forward or moving side wise at the bottom.
A delivery opening is made through the end of each arm D' and also through the
wedge shaped block 3 fixed to the underside of the arm,
. J

page_text: The frusto conical bushing 4 fits in the opening and is supported by a flange at
the top. The bushing can be removed and replaced by one with a larger or smaller
bore by detaching the holding piece 2 and removing the shoot E¹.
The mouth pieces K are secured fast to the inclined bottom of the block 3.
There are brushes m m¹ respectively at front and back of each delivering opening
and at the sides thereof the depending plates l. The bristles of the front brush
preferably extend slightly below the lower edges of these plates in order to make
contact with supply gate I¹ when it is moved forward. It thus acts as a friction
pad to prevent the scale rebounding. The edges of the gate I¹ and also of the
plates are bevilled. Under the mouth piece K is the small spout p. The gate 1¹
is fastened at the upper end of the arm. I whose lower end fits in a socket piece n
in the scale beam just behind the fulcrum. A set screw n¹ retains the arm in
place while allowing its adjustment. In the same socket piece n fits the bent rod 5
which is held in place by the set screw n¹¹. It is screw threaded at the outer end
and carries the nut weights 6 and also the centrifugal balance weights. 7. The
latter are adjustable on the vertical part of the rod being held by a set screw n!!!
and the former on the horizontal threaded part.
The weights are adjusted so that their centrifugal force due to the rotation of the
weighing scales with table C balances that of the arm I and gate I'. The nut
weights are adjusted to give precisely the balance desired in weighing.
Each weighing scale has a package support K¹ with gauge plates L L' on either
side. The gauge plates are supported by and are adjustable on the rods 15 that
project from the sides of the package support.
The package support is mounted on a vertically sliding carrier 37. In the
drawings the carrier slides in the sleeve 8 which itself is adjustable vertically in
the collar 9 of the scale pan. It may however slide directly in the socket in the
scale pan. The former construction is preferable where a very large vertical
adjustment is desired.
Set screws retain the parts in the position to which they may be adjusted. The
scale pan is provided with the conical skirt 10 which extends over the bearings or
knife edges 16 by which the scale pan is supported in the beam. Any material
which may fall past the package does not collect on the scale pan but slides off and
is delivered clear of the bearings..
The knife edges 16 are fixed in the scale beam and project in the arms 17 which
support the scale pan. The front edges of these openings are straight (see Figure 5)
and present a steep inclination to the knife edge so that if pressure in placing the
package on the scale pan for example be applied tending to force back the scale
pan the pressure will be resisted or if the supporting arms ride on the knife edges
they will return to their former position so soon as the pressure is withdrawn.
With the same object the edge 19 of the openings in the supporting arms on which
the knife edges 20 rest are similarly inclined.
At the base of the arm I is a shield 21 which surrounds the arm and extends
over the adjacent part of the scale beam and also over the fulcrum. It is made
with sharply inclined sides as shown in Figure 1 for most materials but where
grains such as bird seed are to be weighed a flat form of shield may be adopted as
shown in Figure 6.
The latch N is pivoted at a to the collar 9 which it surrounds. The upper part
of the latch lies at the back of the scales and is provided with an adjustable
contact fingert which is struck by the package when the latter is placed on the
package support. The lower part of the latch which engages the notch 12 in the
scale frame is at the front of the scale. Stop 11 limits the movement of the latch
and thus prevents the package from being moved too far back on the package
support.
The gear e for rotating the table C¹ is made in one piece or casting with the
frame C. The spindles U slide and turn in bearings in the frame C and in the
brackets Q. They are revolved by the friction wheel W bolted to the pedestal A
and the bevil friction pinions in the spindles. A stationary cam X see Figure 7
00

page_text: raises and lowers the spindles U at the proper time. The lifting device 21 on each
spindle U projects under the corresponding scale beam. Each spindle U carries a
ratchet wheel S for operating tapping arms as described in the specification of the
aforesaid patent of 1882.
These tapping arms need not be used if not desired.
The operation of the machine is as follows:-
The scales being all latched down so that all the gates I¹ are closed and the
proper bushings 4 being placed and secured in the recesses therefor and the
package support K' and the gauge plates L L' and contact finger t being properly
adjusted for the packages to be filled the scale weights being adjusted on the beam
and the nut weights on the screw rod the hopper E is filled to the proper depth
with the material to be weighed and packed and the machine is started. The
table C.being revolved the scales' are successively made to pass the attendant who
is stationed in front of the cam X. As they come opposite him. he places & carton
or empty package M between the gauge plates L L until stopped by the contact
of stop 11 with skirt 10. He is careful to place the side of the carton which has
no flap adjacent to the gauge plate L. This makes the opposite side which has
the longest flap face the mouth of the spout p. This mouth has been made at one
side in order to deliver the material away from the open or flapless side.
The carton or package as it is inserted strikes and pushes back the contact
piece t vibrating the latch N and releasing it from the notch 12. The scale pan
with its carton or package does not however rise immediately because the
spindle U is still raised by the cam X and the device z¹ upholds the scale beam
keeping the gate I' closed. As the spindle U is gradually allowed to descend the
gate 1 opens and allows the material to descend through the spout p into the
carton or package. The descent of the spindle U brings the pinion into contact
with the friction gear W and the said spindle and the ratchet wheel S commences
to revolve. If the tapping arms not shown are in action they are vibrated by the
wheel S and tap on the sides of the carton so as to shake down the material
delivered thereinto. As soon as the proper quantity of material has passed into
the carton or package the scale pan is depressed tilting forwards the arm I and
gate I and stopping the delivery of material. After the delivery ceases the
spindle U is again raised by the cam X. when the full package is removed and a
fresh one put in its place. As soon as the full package is removed the latch N
immediately drops into engagement with the notch 12 and if the attendant should
neglect to insert an empty carton.it would continue to hold down the scale and
keep closed the gate (as shown at the right of Figure 1) until released by the
insertion of a fresh carton or package. Should the attendant not remove a full
package its weight would of course keep the gate I¹ closed.
One of the weighing scales could be provided with its own hopper and be used
as a complete small machine its capacity being of course much less than that of the
machine shown.
The machine shown in Figures 7 to 10 is similar to that just described with
reference to Figures 1 to 6 except in the particulars mentioned below.
É is an annular hopper fixed to and supported by the hollow column D and Fa
spider frame attached to the stationary shaft B. Motion is imparted to the
frame C and table C¹ in the direction of the arrow through the bevil gears c and f
and the horizontal shaft H that is journaled in bearings in the bracket
and is
driven by a belt running on the pulley h.
g
Upon the table are placed weighing scales G say four in number although there
may be less or more. In the bottom of the hopper there are as many openings as
there are scales on the table. The scales are the same as before described with
reference to Figures 1 to 6.
Under each of the openings in the bottom of the hopper is a mouth piece K.
Its lower edges lie in a plane inclined to the horizontal to the same degree as the
gate I when closed. This supply gate works out of contact with but in close
proximity to the said edges.

Above each delivery opening in the hopper is placed an adjustable valve 50 for
regulating the size of opening and thus controlling the delivery. It is attached to
the lower end of the carrier 51 pivoted at 52 to the inner wall of the hopper. A
spring 53 (shown as spiral tension spring) tends to withdraw the valve so as to
uncover the opening but its action is resisted by the screw stop 54. By adjusting
the screw in the proper position the opening can be made larger or smaller as
desired. In connection with these valves a cam 55 is or may be employed. It
is fixed to the spider frame F and is so arranged that as the valve carriers 51 pass.
under it they are turned in the direction nearly to close the valve leaving but a
small opening. The object of this is to combine quickness with accuracy of
weighing. The same stop 54 is so adjusted that almost the desired weight will
have passed through the opening by the time the valve carrier reaches the cam.
During this time the flow may be comparatively. rapid.
When the upper end of the valve carrier strikes the cam the valve is advanced
and the material flows from the hopper in a fine stream which favors accuracy in
weighing. It is not however necessary to use the cam 55 for the valves can be
adjusted so that the stream from the hopper is always small enough to secure.
accurate weighing.
-
The valves 50 are supported above the bottom of the hopper in order to catch
the material and force it into the opening. The better to accomplish this purpose
the edge of the mouth piece K which projects above the bottom of the hopper is
cut away at 56 and the front of the valve which is made thick is bevilled (see
Figure 9).
It is evident that a piece not adjustable to act as a valve could be used for this
purpose of forcing the material into the opening. It is preferred however to make
the valve perform the double function. The valves or raised pieces 50 are assisted
in their work of forcing the material through the openings by the inclined blades 57
which are set at intervals on the stationary curved rod 58. This curved rod is
attached to and supported by the pendent rods 59 from the spider frame F.
As the hopper revolves it carries the substance therein under the inclined blades
which compact the substance at the bottom of the hopper and also force it into
the delivery openings. At the same time they hold back the substance or material
so that it does not move around quite so fast as the hopper. Consequently the
valves or raised pieces plough their way (so to speak) through the compacted
material and the result is a steady and practically uniform delivery of the material
from the hopper.
The material is fed into the hopper from the bin 60 through the spout 61. In
the bin 60 is a stirrer 62 which is kept in continual rotation by a belt or pulley 63.
At the bottom of the bin is the cut off 64 pivoted at 65 to the spout and controlled
by the float 66. This float consists of a metal plate which preferably has the edges
bent down as shown. As the material is carried under the plate it holds it up and
thus regulates the position of the cut off. When sufficient material has collected
in the hopper it stops entirely the flow from the bin.
The tapping apparatus or attachment for shaking down the material in the
packages after it has been weighed into them is placed at the front of the machine.
It consists of a supporting frame 160 a conveyor belt 161 a tapper or tapping
arm 162 arranged under the belt the operating mechanism and the side plates 163
for retaining the packages in place on the belt. The conveyor belt 161 is revolved
at a speed corresponding with that of the table C so that it will hold the packages,
as fast as they are filled with the material It is driven from the pulley 164 on
the shaft H.of the machine through the belt 165 pulley 166 on shaft 67 worm 68
on said shaft and larger worm gear 69 on the journal of pulley 70 at the right end
(Figure 7) of the frame. The belt travels over and when loaded with packages
rests upon the side pieces 71 of the frame.
Between the side pieces 71 is the tapper 162 mounted on the horizontal arm of
bell crank lever 620 supported and turning upon the pin or rod 72. It is vibrated
by the conjoint action of a ratchet wheel 73 and a spring 74 (shown as a spiral

page_text: tension spring) fastened at one end to the short arm of lever 620 and at the other
to a pin on the frame. The ratchet teeth withdraw the tapper against the action
of the spring and when they release it the spring throws it up so that it gives a
smart blow directly upon the underside of the belt and indirectly (that is through
the belt) upon the bottom of the package.
The side plates 163 are supported upon the studs or pins 75 which project
laterally from the side pieces 71 by arms 76 whose hubs fit over the said studs or
pins and are held thereon by set screws so that the said plates are adjustable
towards and away from each other. The packages as they are taken from the
weighing scales are placed upright on said conveyor belt and as they pass over the
tapper have their contents shaken down. The conveyor belt can be extended to
any distance to the workmen whose duty it is to close and seal up the packages.
The belt passes or may pass over the top of a table at which the workmen are
seated.
The operation of the machine or apparatus is as follows:-
The scales being all latched down so that all the gates I¹ are closed and the
valves 50 package supports K gauge plates L L' and the scale weights being
properly adjusted the hopper E is filled to the proper depth say one third with the
material to be weighed and packed the bin is also filled and the machine is started.
The table C¹ being revolved the scales are successively made to pass the attendant
who is stationed in front of the cam X. As they come opposite him he places a
carton or empty package M between the gauge plates L L¹ until he presses back
and releases the latch N. The scale pan with its carton or package does not
however. rise immediately because the rod U is still raised by the cam X and the
device z¹ upholds the scale beam keeping the gate I¹ closed. As the rod U is
gradually allowed to descend the gate I opens and allows the material to descend
into the carton or package.
The powdered material in the hopper is forced through the delivery openings in
a constant stream by the combined action of the inclined blades 57 and valves or
raised pieces 50. If the cam 55 be used the valves 50 are nearly closed as the
scales come under it so that a fine stream is delivered. This change takes place
after the bulk of the charge has been delivered into the package. When the full
charge has been received the scale pan descends closing the supply gate I¹ and
stopping the delivery.
After the delivery ceases the rod U is again raised by the cam X when the full
package is removed and a fresh one put in its place. As soon as the full package
is removed the latch N immediately drops into engagement with the notch 12 and
if the attendant should neglect to insert an empty carton it would continue to
hold down the scale and keep closed the gate until released by the insertion of a
fresh package. Should the attendant not remove the full package its weight
would of course keep the gate I' closed.
The packages as they are removed from the scale are. placed on the conveyor
belt 161 and by it carried above the tapper 162 which shakes down the contents
and thence to the workmen who seal the packages. If it be not desired to use the
tapper it can be thrown out of action by releasing the tension of the retractile
springs 74.
Referring to Figures 11 to 14 the scale beam 100 is supported on knife edges 101
which enter V-shaped openings 102 in the machine frame. The scale pan is
supported at the front (left hand Figure 11) end of the beam on knife edges 103
fixed in the beam which enter V-shaped openings in the arms 104 attached to or
making part of the scale pan. The upright position of the scale pan is maintained
in the usual way by a link in the base of the frame. At the top of the scale pan
is a flat plate 105. On this plate are supported the receptacles 106 (three are
shown) for receiving the material to be weighed. They are open at both ends.
Their lower ends rest upon the plate 105 which is ground or turned off smooth
and forms the bottom to the receptacles. The receptacles are attached to a spider
frame 107 at equal distances from the centre said spider frame has a central hub

page_text: and is pivoted to the plate by a screw 108 passing through said hub and tapped
into the plate. There is a sleeve 109 surrounding the shank of the screw upon
which the hub turns. At each receptacle is a pin 132 and on the plate 105 is a
spring stop 133 which is in the path of the pins 132 but can be depressed to remove
it out of the way when it is desired to turn the receptacles and the spider frame.
At the front of the scale under the plate 105 which is perforated is a small
spout 110 supported by upright rods 111 fixed at their lower ends to the machine
frame. There is also a short tube 150 fastened to the plate 105. Above the scale
pan is the funnel or reservoir 112 supported by the bracket making part of the
machine frame having a delivery opening in the bottom. The hole in plate 105
and the delivery opening in the funnel or reservoir 112 are so placed that when
one receptacle 106 is over the hole the next one is under the delivery opening.
The mouth piece is fastened to the bottom of the funnel or reservoir 112. It has
a brush 114 and 115 at front and back respectively and metallic side walls 116.
The bristles of front brush 114 project slightly below the edges of the side walls.
The supply gate 117 works below the mouth being fastened to the upper end of
the arm 118 whose lower end fits in the socket pieces 119 fastened to the scale
beam and is there held by a set screw. The supply gate is so adjusted that as it
passes under the front brush 114 it makes contact with the same. The lower edge
of the side walls 116 and the front of the supply gate are bevilled.
Above the funnel or reservoir 112 is the hopper 120 removably supported by
the arm 121 fixed to the hopper and resting upon the edge of the funnel or
reservoir. A spout 122 conducts the material to be weighed into the hopper from
an elevated bin. At the mouth of the hopper is a removable bushing 125. Below
the spout is the disk or plate 123 which is upheld by the arms 124 resting against
the inside of the hopper.
To fill small packages a longer bushing with a smaller orifice is used for larger
packages a shorter one with larger orifice. The latch 126 is placed below the
scale pán. It is pivoted at 127 to the scale frame and its upper end is adapted to
engage the front end of the scale beam when the scale pan descends and the latch
is not held back.
A wire 128 is attached to and projects forward from the latch. Its inner end is
clamped beneath the washer 129 which is held by a screw tapped into the latch.
It is therefore adjustable. When the package is placed around the spout 110
the edge thereof strikes the wire and lifts it realeasing the latch and allowing
the scale pan to rise. On the rods 111 on either side of the spout 110 are the
hooks 130 for supporting a bag with its mouth extended. They are so arranged
that when the mouth of the bag is placed over them the edge of the bag holds the
lutch wire 128 in its raised position.
Under the weighted or rear end of the beam is placed a stop 131 so arranged
that the beam makes contact with the upper end thereof when the scale pan has
risen to its full height. As shown the beam is provided in addition to the
adjustable weight with a weight rigidly fastened at the end of the beam. This
need not be used or it may be replaced by a hanging dish to receive removable
weights as common in weighing scales.
•
The operation of the machine is as follows:-
Assuming the scale pan to be latched down and the supply gate closed the
granular material descends through the spout 122 and fills the hopper 120 to or
nearly to the lower end of the spout and the reservoir or funnel 112 to or nearly
to the lower end of the bushing 125 or if no bushing is used to the lower end of
the hopper 120.
•
If the receptacle 106 which at the time is under the reservoir or funnel 112 be
empty the attendant trips with his hand the latch 126 whereupon the weighted
end of the scale beam descends (and at the end of its movement strikes the
stop 131) the scale pan rises and the supply gate 117 is withdrawn. The tendency
of the scale to rebound-is diminished by the action of the stop 131 and the beam
now comes to rest. As soon as the supply gate is opened the material in the

page_text: funnel or reservoir 112 runs rapidly through the delivery opening into the
receptacle 106 until the funnel or reservoir 112 is empty. As the amount (in
consequence of regulation made to that end) is insufficient to bear down the scale
pan the material continues to flow but in a smaller stream through the smaller
orifice of the bushing 125 or of the hopper 120 if no bushing be used. The level
of the material in the hopper 120 is maintained constant by the flow from the
spout 122 the pressure of the column in said spout being taken off by the disc or
plate 123.
When the receptacle 100 has received its charge the scale pan descends and is
automatically latched down. As the supply gate 117 closes it makes a light
contact with the front brush 114 and the slight friction prevents any tendency of
the scale to rebound.
The attendant now places the package under the spout 110 and raises it until
the upper edge strikes and lifts the wire 128 tripping the latch 126 and releasing
the scale. If the package be a bag the edges are caught over the hooks 130 in
which position the edge of the bag holds up the wire 128.
Although the latch is released the scale does not move because the charge is
still in the receptacle 106. The attendant takes hold of the pin 132 and with the
thumb depressing the stop 133 turns the spider frame 107 so as to bring the
charged receptacle over the opening in the plate 105 and an empty one under
the funnel or reservoir 112. The spider frame is stopped at the proper place by
the next pin 132 striking the stop 133 which has been released as soon as the
former pin was disengaged.
The charge in the receptacle which has been brought over the hole in the
plate 105 runs through the spout 110 with the package placed below it. So soon
as the discharge begins the scale pan rises the supply gate is withdrawn and the
delivery into the succeeding receptacle (now under the funnel or reservoir) com-
mences. Thus while one receptacle is discharging another is filling. The filled
package would ordinarily be reinoved and an empty one inserted by the time the
receptacle received its charge..
It is evident that modifications could be made in the details without departing
from the spirit of the invention and that parts of the invention could be used
separately.
