PROVISIONAL SPECIFICATION,
Improvements in Grain Bagging Machines.
We, JAMES WILLIAM HENRY, Blacksmith, of Wallace, Shoshone County, Idaho,
United States of America, ALEXANDER GUNN, Machinist, of Wallace, Shoshone
County, Idaho, United States of America, aud' HARRY PERCY WARD, Undertaker,.
of Wallace, Shoshone County, Idaho, United States of America, do hereby declare
the nature of this invention to be as follows:
This invention relates to a grain bagging machine adapted to support and hold
open an empty bag or sack during the filling operation, to close the open mouth
of the bag by sewing after the bag is filled, and to finally, discharge the filled' and
closed bag from the machine.
The invention consists principally of an intermittently rotating bag carrier pro-
vided with holders each having a fixed jaw and movable jaws to engage the mouth
of the bag, to hold the same open during the filling operation and shut during the
sewing up of the bag mouth. It also comprises a sewing device having a segmental
needle carrying the thread and adapted to pass through the fabric projecting above
the said jaws, the needle being mounted to travel in a fixed circular race, and being
provided with a chamber in its rear end carrying a coil of thread, and being com-
bined with other devices hereafter described for effecting the sewing operation and
for driving the needle around the race.
The invention also comprises certain other combinations of mechanism herein-
after described.
The bag carrier is mounted to rotate on a central vertical shaft and comprises a
bottom or table and a top frame united by adjustable standards to admit of tlic
distance between the table and top frame being varied to suit the size of the bags
which rest on the table whilst their mouths are engaged by the bag holders.
The driving mechanism by which intermittent rotary motion is imparted to the
bag carrier and by which the sewing mechanism is operated comprises a main shaft
actuating an eccentric whose rod is connected with a slide block moving in a
stationary guide and engaging with one arm of a bell crank lever whose other
arm engages by a tooth with notches in the edge of the top of the bag carrier so
as to impart intermittent rotary motion thereto, to allow the needle for sewing up
the bag to work properly as hereafter described, a spring dog engaging with the
same notches to prevent recoil of the bag frame. The top frame of the bag carrier
has four openings in which are arranged four bag holders each comprising a
stationary outer segmental jaw corresponding to the periphery of the top frame and
two inner segmental jaws pivoted at their outer ends to the ends of the outer jaw
and pivoted at their inner ends to a common radially sliding bar by which when the

page_text: .
bar is moved outwards the said inner jaws are pressed against the stationary outer jaw.
Each jaw-operating radial bar is forced outwards by the pressure of a spring by
which the jaws are normally held in the closed position, the opening of the jaws
for the purpose of fixing the mouth of the bag in position being effected by a ver-
tically sliding treadle mounted on the standard of the bag carrier and actuated by
a chain passing over suitable guide pulleys in the jaw-operating slide bar. The
inner jaws have fixed pins and the outer stationary jaw has pins which are retruct-
able as hereafter described.
When the bag has been placed in position in the holder at the front of the
machine, the treadle is released to allow the jaws to close. When the carrier is
now rotated a quarter turn a stud on the jaw-operating bar meets a stationary
ram whereby when another quarter turn is given to the carrier, the radial jaw-
operating bar is retracted, and the jaws are opened by the time that the holder
reaches the rearmost or filling position. The bag is now filled, another quarter
turn is given to the carrier, the jaws are closed by the spring, and the mouth of the
bag is thereby held closed during the time it is sewn up while the bag is passing
from the fourth position back to the front of the machine.
The outer fixed jaw is formed by a peripheral portion of the top frame of the
carrier and the set of pins for that jaw are parallel, project through holes in the
jaw, have notched points, and are attached to a common holder in the form of a
segment of a circle fitted to slide in the radial direction and provided with oblique
slots on its upper face with which engage pins affixed to a longitudinally sliding
segment with which engages the crank pin of a vertical shaft provided with a handle
by turning which sliding motion is imparted to the segment and the pin-carrying
block is moved inwards or outwards as the case may be! By this means the pins
may be made to project from the inner face of the fixed jaw so as to engage the
fabric of the bag mouth and to securely hold the bag mouth in the open position
when the movable jaws are retracted for the filling operation. When the points
of the pins are retracted within the fixed jaw, the bag being then filled and sewn
up, the pins are thereby disengaged from the closed up mouth, to allow of the
removal of the bag.
The device for sewing up the mouth of the bag whilst the latter passes from the
fourth to the first position is as follows:-The main shaft before referred to is
movable in a tangential position above the periphery of the bag carrier and on its
end is a wheel having radially sliding needle drivers fitted therein adapted to
engage in openings in the circular segmental needle, the needle drivers being
radially moved by engagement with a cam groove in a stationary dise concentric
with the shaft. In this disc is formed an annular race for the segmental needle to
travel in, the latter being carried round by the needle drivers as the shaft is rotated.
At the lower part of the stationary disc is a notch intersecting the annular race
through which notch passes the doubled up edge of the bag mouth extending above
the closed jaws as the latter pass from the fourth position back to the first position.
By the action of the cam the needle drivers are separately retracted from engage-
ment with the needle each at the moment when it is passing the sewing point so
that there is always one in engagement with the needle for driving it around in
the race. The heel end of the needle is chambered to receive the coil of thread and
is provided with a spring closed hinged cover. The sewing thread is doubled and
formed into a coil with the doubled middle portion extending lengthwise through
the coil, passing through a tension device at the heel end of the needle formed of
a pair of elliptic springs, and with the outer loop or bight adapted to be hooked
upon a pin carried by a plate pivoted on the race in such position with regard to
the sewing notch or gap that when the needle is caused to travel in the race it
will pass through the bag material and through the loop of the sewing thread
and as the cord is now drawn tightly the loop will slip off the pin and lock the
first stitch in the bag, the cord or thread being carried through the bag material
within the needle and over it so as to form a succession of overcast stitches. The
coils or spools of thread are so formed that the thread is unwound from the forward

page_text: end drawn through the centre of the coil, the outer coil being the last to unwind.
The needle is semi-circular so that it occupies one-half of the race and the feed
is so arranged that ample time is given to the needle to pass clear through the
material before the bag is moved forward by the intermittently moving bag carrier.
On the standards of the bag carrier and on a sleeve on its shaft are journalled
the trunnions of the throw-off boards which normally stand vertically above the table
and are adapted to form back rests for the sides of the bags. The upper end of
each board is connected by a short chain with the chain by which the corresponding
jaws are opened so that when the treadle is depressed and the corresponding jaws
are opened the throw-off board is tilted, its upper end inwards and its lower end
outwards, to throw the filled and closed bag off the table, the jaws opening in
advance of the tilting motion by which the bag is thus thrown off.
The whole operation of the machine may be thus summarized:-The jaws at
the front of the machine having been opened by depressing the treadle, the bag is
placed on the pins of the jaws and the jaws are then allowed to close so that the
mouth of the bag is clamped between the outer fixed jaw and the inner movable
jaws. The driving belt is now thrown on to the fast pulley and rotary motion
given to the bag carrier by the mechanism above described so as to move the bag
from the first to the second position and bring the jaw-operating radial bar in con-
tact with the jaw opening cam by which during the second quarter revolution of
the bag carrier the jaws are opened so as to hold the bag mouth open when it
reaches the third or rearmost position. While in this position the bag is filled
with grain, it being understood that the belt is shifted from the fast to the loose
pulley after each quarter revolution of the bag carrier so as to give time for filling.
During the next quarter revolution the mouth of the filled bag is closed by the
jaws. In passing from the fourth position the edge of the bag mouth projecting
above the jaws passes the sewing point and during the last quarter revolution the
needle travelling around in its circular race sews up the mouth of the bag. When
the bag finally arrives at its first position the pins of the fixed jaw are retracted,
the movable jaws are opened, the throw-off board is tilted, and the filled and
sewn-up bag thrown off:

Improvements in Grain Bagging Machines.
We, JAMES WILLIAM HENRY, Blacksmith, ALEXANDER GUNN, Machinist, and
HARRY PERCY WARD, Undertaker, all of Wallace, in the County of Shoshone and
State of Idaho, United States of America, do hereby declare the nature of our
invention and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement:-
The object of the invention is to provide a new and improved grain bagging
machine arranged to properly support and hold open an empty bag or sack during
the filling operation, to close the open end of the bag by sewing, after the bag is
filled with the grain, and to finally discharge the filled and closed bag from the
machine.
The invention consists principally of an intermittently rotating bag carrier pro-
vided with holders, each having a fixed jaw and movable jaws to engage the mouth
of the bag, to hold the same open during the filling operation and shut during
the sewing and closing of the mouth of the bag.

page_text: The invention also consists of certain parts and details and combinations of the
same, as will be fully described hereinafter and then pointed out in the claims.
Reference is to be had to the accompanying drawings forming a part of this
specification, in which similar characters of reference indicate corresponding parts

The improved machine is mounted on a suitably constructed frame formed with
a base A, posts or columns A', and a top plate A³, in which said base A is screwed
a vertically disposed shaft B, on which is mounted to turn the bag carrier C pro-
vided at its lower end' with a table C resting on a collar B' attached to the shaft B.
The bag carrier is also provided with a top C resting on the collar B secured to
the shaft B, and the said top is connected with the table C1 by adjustable standards,
each formed of two pieces C3, C4, fitted to slide one on the other, and adapted to
be secured' together by bolts C5 after the desired distance is obtained between the
table C and the top C. It. is understood that when an adjustment is made to
increase or diminish the distance between the table C' and the top C³, the standards
are adjusted and the table C¹ is moved up or down with the collar B' adjusted
accordingly on the shaft B. This arrangement is necessary for different sized bags.
to be filled with grain, the said bags resting with their lower ends on the table C¹,
and the upper ends or the mouths of the bags being engaged by bag holders, aq
hereinafter more fully described.
The bag carrier C is rotated by mechanism driven from the main driving shaft D
journaled in suitable bearings on the top plate A2 of the main frame, and this
shaft D is provided at one end with fast and loose pulleys D', connected by belt
with suitable machinery for imparting a rotary motion to. the shaft D. On the
latter is also secured a beveled gear wheel D° in mesh with a'beveled gear wheel D³,
secured on the shaft D' journaled in suitable bearings attached to the main frame,
as plainly indicated in Figures 1, 7 and 8. The outer end of the shaft D is pro-
vided with a hand wheel 5 under the control of the operator, and on the said shaft
is also secured an eccentric E connected by its eccentric rod E with a block E²
fitted to slide in a suitable casing A attached to the main frame. In the block E2
is formed an opening E3 (Fig. 7) into which extends one end of a bell crank
lever E, fulcrumed upon another slide whose movement in the casing A inde-
pendently of the block E is limited by the stop pin shown in Figure 7 and
the said lever E is provided with a tooth F adapted to engage with the gear
wheel C formed on the peripheral edge of the top C3 of the bag carrier C, so as
to impart a rotary motion to the same when the shaft D is rotated, as before
4

page_text: described. It is understood that the reciprocating block E imparts first a
swinging and then a bodily travelling motion to the bell crank lever E and the
latter by the tooth E meshing into the teeth of the gear wheel Co, causes the
bag carrier to rotate in the direction of the arrow a¹, the return movement of
the latter being prevented by a spring dog E6 in the casing A. Thus an inter-
mittent forward motion is given to the bag carrier, to allow the needle for sewing
the bag to work properly, as hereinafter more fully described.
The top of the bag carrier C is cut out at four places to form openings in which
are arranged four bag holders F, each formed with a fixed segmental jaw F' in-
tegral with the top C, and the two movable segmental jaws 13 and F pivotally
connected at their ends to the top C, and pivotally connected at their inner or
free ends with a radial bar G fitted to slide in suitable bearings C formed or
attached to the top C. The pivotal connection between the bar G and the movable.
jaws and is made by means of a pin in the bar G, the said pin passing through
elongated slots in the free ends of the jaws F2 and F3; so that on moving the
bar G radially inward or outward, the jaws F2 and F3 are opened or moved into a
closed position, as illustrated in Figure 1.
Each of the bars G is provided near its outer cud with a depending lug carry-
ing a radially extending rod G3, fitted to slide at its inner end in a bearing formed
on the under side of the top C³ (see Figure 2). On this rod Gis coiled a spring G³
resting with one end against the aforesaid bearing, and with its other end abutting
on the lug G. The spring G³ serves to move the bar G into an outermost posi-
tion so as to hold the movable jaws F2 and F3 normally in a closed position, as
indicated at the left and right in Figure 1.
The lug G of each bar G is also connected with one end of a chain G4 passing
around pulleys G and Go, journaled on the top C3, the chain extending down-
wardly from the pulley Ge to connect with a vertically disposed arm G7 fitted to
slide vertically in suitable bearings attached to the standard parts C3 previously
mentioned, each arm G being provided at its lower end with a foot piece 8, adapted
to be engaged by the foot of the operator to press the foot piece downward to impart
a sliding motion to the arm G' in the same direction, so as to exert a pull on the
chain G, to pull the corresponding bar G inwardly so as to open the movable
jaws F2 and F3, as indicated at the front and rear in Figure 1. When the front
holder F has its jaws F and F in an open position, as shown in Figure 1, the bag
is attached with its mouth to the said jaws by means of fixed pins F on the mov-
able jaws F and F, and by pins F forming part of the fixed jaw F¹, but laterally.
movable thereon, as hereinafter more fully described.
When the bag has been placed in position on this holder, the operator releases
the pressure on the footpiece G to permit the spring G³ to push the bar G with
its holder outward to close the jaws. When the carrier C is now rotated, or given
a quarter turn, the closed jaws move into the position shown at the left in Figure 1.
A friction roller G on top of the bar Gnow moves in engagement with a
cam G10, fixed to the under side of the top plate A2 of the main frame, and when a
quarter turn is now given to the carrier C, this friction roller G in travelling along
the fixed cam G causes the bar G to slide inward, so as to bring the jaws Fa
and F3 of this holder into an open position at the time the holder moves into a
rearmost or filling position, as indicated in Figure 1. The bag is now filled; and
when this has been done, another quarter turn is given to the bag holder C, so that
the friction roller G9 passes off the cam Go, to permit the spring G³ to act on the
bar G and close the jaws F3, F3, so as to hold the mouth of the bag over the grain
contained in the bag, during the time the bag is closed by sewing, while the bag
passes from the fourth position back to the first position at the front of the machine.
Each of the fixed jaws forms an integral part in the form of an upwardly extend-
ing segmental flange of the ring C8 of the top Ca of the bag carrier, as plainly
indicated in Figures 2 and 5. The pins 5 extend parallel' one to the other and
pass through openings in the jaw and the set of pins for each jaw are attached
to segmental blocks F fitted to slide on top of the ring C in the rear of the jaw F¹.

page_text: On the top of each block F are formed oblique recesses F7, each engaged by a
pin I depending from a segment H, fitted to slide on the top of the ring C and
held in place thereon by bolts H³, passing through segmental slots II³ formed in
the segment H. On the under side of each segment H is formed a recess II (see
Figures 5 and 6) engaged by the wrist pin of a crank arm H formed or secured
on the upper end of the shaft He arranged vertically and mounted to turn in suit-
able bearings in the ring C8.
On the lower end of the shaft H is secured a handle H adapted to be taken hold
of by the operator to impart a turning motion to the shaft II so as to cause the
crank arm H to impart a sliding motion to the segment H, to shift the block F
inwardly or outwardly according to the motion given to the handle H. The
block F by moving outwardly, pushes the pins F5 a suitable distance beyond the
inner face of the fixed jaw F, so as to securely engage the web or fabric of the
mouth of the bag, to securely hold the mouth of the bag in an open position when
the jaws F and F move inward, carrying along the inner part of the web or fabric
of the mouth of the bag to hold the mouth open during the filling operation. When
the block moves outwardly, the points of the pins are partly withdrawn
in the fixed jaw F1, and when this takes place the bag is in a filled position at the
front of the machine, and the withdrawing of the pins disengages the fabric of
the bag so as to release the closed up mouth to allow the removal of the bag from
the table C. Each of the pins F is preferably provided on top with a transverse
notch (Fig. 4) to retain the fabric of the bag in place as long as the pins are
in an outermost position and during the time the bag is being filled
The device for sewing up the mouth of the bag while the latter passes from the
fourth to the first position is arranged as follows, special reference being had to
Figures 8 to 14.
On the end of the shaft D is secured a wheel' I, formed on its inner face with
radial grooves I and I, engaging blocks 13 and I, respectively, extending with
their outer ends into openings Ji and J2, respectively, formed in the segmental
needle J. The blocks I³ and I are provided near their inner ends with pins [*
and I, engaging the cam groove K¹ of a disk K, provided with a hub K rigidly
supported on the main frame and through which passes loosely the forward end of
the shaft I). In the disk K is formed an annular race K³ for the segmental needle J
to travel in, the latter being carried around by the blocks 13 and I as the shaft D
is rotated, the said blocks being carried around by the wheel I before mentioned.
In the under side of the disk K is formed a transversely extending recess K'
through which passes the doubled up edge of the mouth of the bag, the said edge
extending above the closed jaws F1, F2, 3, as the latter pass from the third to the
fourth position and from the fourth position back to the first position, as will be
readily understood by reference to Figure 1.
Now during the time the needle J passes through the doubled-up edge of the
bag, the corresponding block I³ or I is moved inwardly by the action of the pin Is
or I travelling in the cam groove K', the latter being shaped so as to move the
corresponding block into an innermost position at the time the block-passes over
the recess K. Thus both blocks are always in engagement with the needle J for
pushing the same around in the race K³, except when one of the blocks I, I, is
drawn inwardly to pass the recess K. The forward end of the needle J is provided
with a point J³ and the rear end thereof is made hollow and provided with a
hinged plate J held in the closed position by a spring J5 but adapted to be opened
to place the coil of thread L in position in the hollow part of the needle, as
shown in Figure 15.
The sewing thread is doubled up and formed into a coil with the doubled-up
middle portion extending lengthwise through the coil, and with the outer loop LI
adapted to hook upon the hook K' of the plate KB fulcrumed on the ring K6, at
the side of the recess K. The doubled-up ends of the coil of thread L pass through
a tension device N, fitted into the outer end of the hollow portion of the needle, to
give the desired tension to the thread passing through the fabric or material of

page_text: the bag. The tension device is formed with two longitudinally extending elliptic
springs N1, N2, having their convex sides inward towards each other, as shown
in Figure 16.
Now when the several parts are in the position as shown in Figure 15 and the
ucedle is caused to travel in the race K³, the needle passes through the bag material
and the loop L' of the sewing thread at the hook K, and, as the cord is now drawn
tightly, the loop slips off the hook K' and locks the first stitch on the bag. The cord
or thread is carried through the bag material within the needle and over it so as
to form a succession of over cast stitches. The coils or spools of threads L are so
formed that the thread is unwound from the forward end and drawn through the
centre of the coil; the outer coil being the last to unwind. The needle occupies
one-half of the race K³ in which it is carried, and the feed mechanism above
described is so arranged that ample time given to the needle to enter and pass
through and be clear of the bag, before the bag is moved forward by the inter-
mittently moving bag carrier.
On the standard pieces C of the bag carrier and on a sleeve on the shaft B,
are journaled in suitable bearings the trunnions O' of the dumping or throw-off
boards O, which normally stand vertically above the table C and are adapted to
form back rests for the sides of the bags. The upper end of each board O is con-
nected by a short chain 03 with the corresponding chain G, so that when the'
treadle or foot piece G³ is pressed by the operator and the corresponding jaws are.
opened, a pull is exerted by a chain G on the chain 0 to tilt the upper end of the
dumping board 0 inward and the lower end outward to throw the filled and closed'
bag off the table C. The chain 03 is somewhat slack to permit the jaws to open
before the board commences to throw the bag off.
The operation is as follows:-
;
When the several parts are in position, as illustrated in Figure 1, the jaws F³
and Fat the front of the machine are opened by the operator pressing the cor-
responding foot piece G³. A bag is now placed on the pins 1 and F³, after which
the operator removes his foot from the foot piece G8 to permit the corresponding
spring G to close the jaws 12 and 1, as previously explained, so that the two
sides of the mouth of the bag are pressed against each other or clamped between
the fixed jaw F¹ and the movable jaws F3, F3. The operator now shifts the belt
from the loose to the fast pulley D¹, so that the shaft D is rotated and a rotary
motion is now given to the bag carrier C by the mechanisin above described, to
move the bag from the first to the second position, so as to bring the fric-
tion roller in engagement with the cam G¹ In the second quarter revolution
of the bag carrier, the jaws F3, F3, are opened, so as to hold the mouth of the
bag open at the time it passes to the third or rearmost position, and while in this
position the bag is filled with the grain, it being understood that the belt is shifted
from the fast to the loose pulley after each quarter revolution of the bag carrier.
has been made, so as to give sufficient time for filling the bag. During the next
quarter revolution, that is, after the bag has been filled, the movable jaws F³, F
close by the action of the spring G³ at the time the friction roller G passes off the
cam Go, so that the mouth of the bag is closed when the bag arrives at the fourth
position. The projecting edge of the mouth of the bag, above the jaws, now passes
into the recess K, and during the last quarter revolution the needle J is caused to
travel around in its circular race K³ to sew the edges of the mouth of the bag,
as previously explained. When the bag finally arrives at its first position, its
mouth is sewed up and the operator now turns the handle H7 so as to withdraw
the pins, and then presses the foot piece G8 so as to open the movable jaws F
and F3. As the movable jaws F2 and F swing inward, their teeth F4 move out
of the meshes of the fabric of the bag, and, as the pins F5 have been withdrawn,
they are also out of engagement with the fabric, and, consequently, the mouth of
5 the bag is wholly free from the jaws; and at this time the dumping board O turns,
as before explained, so as to throw the bag off the table C. Another empty bag

page_text: is now inserted in the jaws and hung on the pius F, F5, after which the operator
releases the foot piece G8 to permit the jaws to close, as before explained.
The above described operation is then repeated.
