COMPLETE SPECIFICATION (AMENDED):
Improvements in Sack Filling and Sewing Machines.
I, ARTHUR T. TIMEWELL, of 3,236, Lake Park Avenue, Chicago, in the County
of Cook and State of Illinois, United States of America, Gentleman, do hereby
declare the nature of this invention, and in what manner the same is to be
performed, to be particularly described and ascertained, in and by. the following
statement:
My invention relates to apparatus for filling sacks or bags with grain or other
material, and closing or sewing the mouth of the sacks or bags after they have
been filled.
The object of my invention is to provide an automatic machine or apparatus of
a simple and efficient. construction, by means of which sacks or bags may be
rapidly, conveniently and evenly filled, teach with a fixed or measured amount of
material, the mouths of the sacks or bags securely sewed, and the filled and sewed
sacks or bags discharged from the machine.
And, to this end my invention consists, primarily, in the combination with a
filling and weight or bulk measuring mechanism for delivering the requisite
quantity of grain or other material into each sack, of an opening and closing
movable or traveling sack holder for holding the sack open while being filled,
closing the same and holding it closed while being carried past the sewing
mechanism and sewed, a sewing mechanism fixed on the frame of the machine,
a conveyor mechanism for supporting and conveying the filled sack from the
filling position past the sewing mechanism and discharging the filled and sewed
sack from the machine. It also consists, in connection with a stationary sack
filling device and a stationary sewing device or mechanism, of a series of two or
more similar movable or traveling and opening and closing sack holders to
enable one sack to be filled and another sewed and discharged at the same time,
thus greatly increasing the capacity of the machine. It also consists, in connection
with the filling device and stationary sewing mechanism, a sack holder and à
track or way along which the sack holder travels on the machine, and the carrier
for supporting and conveying the filled sack in an upright position under and
past the sewing mechanism, of yielding or spring supports for said carrier, so
that the yielding of the carrier may compensate for any variation or inaccuracy in
the action of the cooperative filling mechanism. By combining with the stationary
sewing mechanism and sack conveyor a filling mechanism which operates to
deliver an approximately measured quantity to each bag, I, in a great measure,
prevent any considerable variation in the height or length of the filled bag and
the consequent weight or strain of the filled bag or its holder against the sewing
mechanism or its support; but to further perfect the machine and guard against
danger of injury to or stopping of the mechanism by the attempt to pass through
the machine filled bags of undue height or.length, I mount the bag carrier, or

page_text: that portion of it which conveys the bag under the sewing mechanism, on
springs or yielding supports, so that the distance or space between the carrier
and the table or frame upon which the sewing mechanism is mounted and along
which the bag holder travels, may automatically accommodate itself to the length
or height of the filled bag. My invention further consists, in connection with
the bag filling mechanism and opening and closing traveling bag holder, of the
track or way along which the bag holder travels, and a device or mechanism for
moving said bag holder along said track or way into engagement with which
the bag holder is thrown by the act of closing the same. It further consists in
connection with the filling mechanism, sewing mechanism, traveling bag holder,
of a device for automatically cutting the thread and holding the severed end of the
thread. It also consists, in connection with the filling mechanism and sewing
mechanism and series of bag holders, of a track or way along which the bag holders
travel from the filling position past the sewing mechanism to the discharging
position, said track or way for the holders having an open mouth at the discharge
end of the machine so that no injury can result to the mechanism by one holder
following another successively. It further consists, in connection with the bag
filling mechanism and sewing mechanism, of an open and closing traveling sack
bolder furnished with movable or withdrawable hooks or teeth for disengaging
the mouth of the sack from the holder after the sack has been sewed. It further
consists in the novel construction and combinations of parts and devices herein
shown and described, and specified in the claims.
In the accompanying drawing, which forms a part of this specification, I have
illustrated at Fig. 1 and Fig. 1 in side elevation, a machine embodying my
invention; Fig. 2 is a plan view, somewhat enlarged; Fig. 3 is a partial vertical
section taken on line 33 of Fig. 1; Fig. 4 is an enlarged detail vertical cross
section through the sewing mechanism on line 4-4 of Figure 2; Fig 5 is an
enlarged detail plan view of the sewing mechanism; Fig. 6 is an enlarged plan
view, partly in section, of one memeber of the thread cutter and holder; Fig. 7
is an enlarged detail plan view of the sack holder, showing the same open ;
Fig. 8 is a similar view showing the same closed; Fig. 9 is an enlarged cross
section on the line 9-9 of Fig. 8; Fig. 10 is a detail view illustrating the means
or arrangement by which the closing of the bag holder operates to throw it into
engagement with the gear mechanism for propelling it along its track or way;
Figs. 11 and 12 are enlarged detail views of parts hereinafter to be described.
In the drawing, the same parts appearing in different figures, are indicated by,
the same letters of reference.
In the drawing A represents the frame, B the filling and measuring device,
C the sewing device or mechanism, D the movable opening and closing bag holder,
F the slotted track or way along which the bag holder is moved, G and H are
carriers for supporting and conveying the bag past the sewing mechanism from
the filling position to the discharging position, and K the thread cutting and
holding device.
The bag filling and measuring device B is preferably one adapted to measure
by bulk instead of by weight, and comprising preferably a measuring chamber or
hopper B of a capacity corresponding to that of the bag, a discharge spout B²,
a delivery spout 13 and two valves B 15, and an operating lever B, the upper
valve and lever being long enough and arranged so that the upper valve is
completely closed before the lower one begins to open. By this means a definite
quantity of material is filled into each bag.
5
The sewing device or mechanism C has a frame C¹ upon which the needle, looper
and other parts are mounted; and which frame C is fixed by suitable screws or
bolts c to the frame A, or the top piece or table A¹ of said frame A. The bolt c
extends through only one end of the sewing machine frame C, thus leaving
the other end of said frame C¹ free; so that the needle C² and looper C³, and other 5
co-operative parts of the sewing mechanism may not be affected or thrown out
of-proper engagement with, or relation to, each other by any vibrations of the

page_text: frame A or its table A¹, as might be the case if the sewing machine frame C¹
were supported or attached to the table A' at both sides of the slotted track or
way F. The frame plate A' has an opening A2 to receive the sewing device C,
as is clearly illustrated in Figs. and 5, so that the needle C² may reciprocate
in said opening just below the upper surface of the table or plate A¹ and across
the slot of the slotted way F, along which the bag holders I travel or move, so
that the line of stitching is made just beneath the lower edge or surface of the bag
holder. The sewing machine frame C is arched over the slotted way to give
room for the bag holders to pass between the same and the track F on the frame
plate A The sewing mechanism may be of any suitable form or kind known to
those skilled in the art, that however which I prefer to use in practicing my
invention is illustrated in the drawing, and comprises a reciprocating, needle C³,
a continuously revolving looper C³, a presser foot C4, and suitable means for
reciprocating the needle and revolving the looper, consisting preferably of an
upright shaft C17 carrying a gear 05 provided with a crank pin C, a pitman C,
connected at one end to said crank pin and at the other end to a crank
arm (8 on a crank shaft C, the other arm, Co, of which is con-
nected by a pivoted link C" with the needle bar C2, the same upright shaft C17
is provided with gear C3 meshing with an intermediate gear C4 that meshes
with a gear C15 on the shaft C₁ of the looper.
The series of bag holders D, two or more in number, so that the bag in one may
be filled while that in another being sewed and discharged, each consist, preferably,
of four bars D¹, D', D¹, D', hinged together at their ends by pivots 12 so that
they may be opened to assume a diamond-shape, as illustrated in Fig. 7, or closed
together in a straight line, as illustrated in Fig. 8. A spring D³ coiled around
one of the pivots 12 serves to throw or hold open the holder normally. The
holder D, or each of its hinged bars D1, is provided with a series of movable or
withdrawable hooks or pointed pins or devices to engage the mouth edge of the
sack. These movable or withdrawable hooks d on which the sack is hung, are
preferably fixed to rock shafts d', one on each bar D¹, by rocking or rotating which
the hooks may be withdrawn or moved from engagement with the sack in order
to discharge the sack from the holder. The hooks d or the rock shafts are
preferably held in their normal position-that for their withdrawal from the
sack by springs, preferably coiled around the rock shafts ; and the rock
shafts are preferably rotated or rocked to throw the hooks into position for
hanging the sacks thereon automatically by the act of opening the holder to
receive the sack. This automatic movement of the hooks from their sack dis-
charging or withdrawing position to their sack hanging or receiving position
may be accomplished by any suitable means or mechanism. A simple and con-
venient means for accomplishing this purpose is illustrated in the drawing, and
consists in providing each of the hook bearing rock shafts with a curved or cam-
shaped arm that engages projections on the pivoted bars D', as is clearly
illustrated in Fig. 9, taken in connection with Figs. 7 and 8. The projection or
part on the bar D that is engaged by the opposite curved arm is, as
illustrated in the drawing, also the bearing or housing for the rock shaft d¹.
By this means, as the contiguous pivoted bars DD are thrown open or separated,
the curved arm 3, engaging the projection d, inclines the hooks upward into
As, or when,
position for conveniently receiving and hanging the sack thereon.
the bars D D are closed the curvature or cam-shape of the arm permits the
springs to throw the hooks d into a horizontal position, so that the further
lateral opening or separation of the bars DI DI withdraws the hooks d from the
sewed seam of the filled sack. This will be readily understood from Figs. 9, 7, 8
and 2.
The track or way on the top plate A' of the frame A is provided with a
longitudinal slot f to receive or accommodate the seam or the closed mouth edge
of the bag. This slot f is enlarged at the filling station into a diamond-shaped
opening to receive and accommodate the open mouth of the bag at the time it is

page_text: being filled. The track or way I for the holders 1) has an enlargement F1 at the
filling station to receive or accommodate the holder in its open form, and another
enlargement 3 at the discharge end of the machine to permit the holder to
open and the filled and sewed sack to be released from the holder; that is to say
the two side walls of the track between which the holders pass, conform to the
closed form of the holder at that part of the track where the holders are being
carried past the sewing mechanism, so that these side walls will serve to keep
the holder closed as well as to properly guide the same along; and these side
walls ffdiverge at the filling station F to give room for the holder when it is
open. And these side walls ff, again diverge at the discharge point F2 to permit
the bars of the holder to open to. discharge the filled and--sewed sack. The
track at the filling station has a closed end or abutment against which the
rear end of the holder D abuts, so that the act of closing the open holder will
serve to project the front end of the holder forward and thus throw the holder
into engagement with the mechanism for propelling the holder along
the track F. This is clearly illustrated in Fig. 10 in connection with Fig. 2. The
track F has an open end or mouth F at its discharge end, so that one holder
following another may not be obstructed or stopped by the holder ahead of it,
as might be the case if the track F had an abutment or closed end at the discharge
end of the machine.
The means for supporting and conveying the sack from the filling station past
the sewing mechanism to the discharge position, consists preferably of two movable
carriers G and H, in order to permit the bag to be conveniently shook or vibrated
up and down at the time it is being filled. Both these carriers are preferably of
the endless belt type. To shake or vibrate the bag up and down at the time it
is being filled, the carrier G which supports the bag at this time and serves to
move it onto the other carrier H, is mounted on an up and down movable or
vibrating frame G¹, and to enable this carrier G and its frame to vibrate up and
down conveniently, I furnish the same with a counter balance G2. the counter
balance being preferably in the form of a coiled spring, connected at one end to the
main frame of the machine and at the other to the vibrating frame G¹, the con-
nection to the vibrating frame G¹ being preferably made through the mechanism
which supports and operates or vibrates the frame G'. The frame G is supported
and vibrated by the crank arm or lever G4 on the shaft G³ of the pulley or
wheel G, in connection with the rope or chain G7, attached at its two ends to
the frame G passing over or around the pulleys or sprocket wheels G, G8. The
chain G is secured at an intermediate part of its length to the periphery of the
pulley Go, one strand of the chain passing directly down to one side of the
frame G, and the other strand of the chain passing over the pulley G8 and thence
down the other side of such frame G so that both sides of the frame may be
raised and lowered evenly and simultaneously from the crank G4.
At the oppo-
site end of the frame G a similar chain G7, as indicated in Fig. 3, is similarly
arranged, so that the frame G¹ is thus supported at each of its four corners by
the chains G7. The carrier G travels on pulleys or sprocket wheels G3, G4, on
shafts G5, G6 journaled on the frame G¹, and the same is intermittently operated.
That is to say the carrier G remains stationary while the bag is being filled and
is then set to moving or revolving in order to convey the filled bag onto the
carrier H, which preferably moves continuously. The carrier H travels on pulleys or
sprocket wheels H', the shafts H2 of which are journaled on the frame H³, which
is provided with yielding or spring supports H, so that the frame H may yield
or give when necessary, to give room for a high or abnormally long bag between
itself and the top plate A¹ of the frame or the bag holder track or guide F,
mounted thereon. This insures against danger of stoppage, breakage or injury
arising from the irregular length or height of the filled bags, and is a matter of
importance and value in the practical operation of the machine, as I have found 5
by my experiments.
The thread cutting and holding device or mechanism K, consists preferably of

page_text: two sliding spring actuated bars k, mounted on the frame plate A¹ of the machine,
and each provided with a pin or roller k¹ projecting in the path of the holders D
in the track F, and each furnished with a knife or cutter and thread holding
jaw, so that the instant the holder I passes the projection the sliding
bars, carrying the knives and thread holding jaws, will be actuated or closed
against each other by their springs and thus sever the thread and hold the
free end of the same. When the next holder advances into position for the bag
therein to be sewed, the thread cutting and holding sliding bars kk are automati-
cally retracted into position for the succeeding operation.
Any suitable means or mechanism may be employed for closing the open
holder D at the filling position after the sack is filled; that which I prefer is
illustrated in the drawing, and consists of a pair of sliding bars M, M, mounted
on the frame of the machine in suitable guides M, furnished with anti-friction
rollers mm, adapted to engage, the holder bars D' D¹, and actuated by bell crank
levers M2, M2, connected by rods M3 M3 with the levers MM, which are pivoted
together at m' and to the frame at m² m², and one of which is furnished with a
treadle M6, so that the two slides M M are similarly and simultaneously operated.
Any suitable means may be employed for propelling or moving the holders D
along the track or way F from the filling position past the sewing mechanism to
the discharging position; the means which prefer to employ consists in the
gears NN, mounted above the track F, one on each side of the sewing mechanism,
and which engage rack N₁ secured to the holders D. The act of closing the holder
pushes the same forward and throws its rack NI into engagement with the first
gear N, as the holder is elongated by the act of closing the same.
The gears N
are secured to the shafts N2, having gears N3 which mesh with gears Non
shafts N³, carrying gears N that mesh with the gear N7 on the driving shaft 1.
The sewing machine may likewise be operated in any suitable manner, but pre-
ferably by a bevel gear Pengaging the bevel gear C, the bevel gear P being
secured to a sleeve 1" which is thrown into gear with the driving shaft P2 by a
sliding clutch 7, which is operated automatically by an arm or lever 21 projecting
into the track F into the path of the bag holder D. A spring 22 serves to retract
the clutch and throw the sewing machine out of gear when the sewing of the
bag is completed and the bag holder 1) is carried past said clutch operating arm 7.
The carrier G and the carrier H may both be conveniently driven by a single
sprocket chain T, engaging a sprocket wheel T on the shaft N², and extending
over or around the sprocket wheels T2 T3 of the carriers G and H, and over or around
the idlers T T and T. The sprocket wheel T on the vibrating carrier platform G'
is thrown into engagement with the driving shaft of the carrier G by a sliding
clutch g, having a pin g' which fits in a stationary cam groove g² attached to
the frame of the machine, so that when the frame G¹ is raised up to its full
limit to bring the carriers G and H about on a level, the intermittently operating
carrier G will be thrown into opération.
The operation of the machine is as follows:
The bulk or weight measured quantity of material necessary to fill a sack being
In the measuring chamber 13 of the filling mechanism B, and on open sack
holder with a sack attached being in position on the track F a the filling posi-
tion F, the operator opens the lower valve of the measuring chamber or hopper and
ills the sack, at the same time shaking the sack up and down if necessary by operat-
ng the vibrating carrier platform G¹ with the lever G4; after the sack has thus been
illed with a definite and measured quantity of material, the operator with
rank G lifts the carrier frame G¹, and thus through the action of the clutch
ets the carrier G in motion, and the operator, momentarily after this, with his
oot on the treadle M6 operates the sliding bars M and closes the bag holder D,
nd thus simultaneously throws the bag holder into engagement with its pro-
elling mechanism or gear N. The closed bag holder and bag are then conveyed,
he former along the track F and the latter on the carriers G and H past the
ewing mechanism C, which is automatically set in operation by the movement
g

page_text: of the holder D along the track F, as before described. After the sewing is
completed and the bag holder passes beyond the spring actuated thread cutting
and holding device, the two opening and closing parts of this device automatically
close and sever the thread from the bag, and at the same time grasp the free end
of the thread. The bag holder continuing its movement along the track F, after
passing the point where the side walls ff of the track diverge is then automati-
cally thrown open by the spring D3 at one of the pivots of the holder; and as
the bars D'D' of the holder open or separate, the hooks or pins are withdrawn
from the sack; and the further movement of the carrier H discharges the sack
from the machine. In the meantime another holder of the series has been placed.
in the machine at the filling position and filled in the same manner, so that the
operation is successively continuous.
The spring supports H+ for the carrier frame H' are attached to the frame A
through adjusting screws H³ so that the height of the carrier H may be adjusted
for operation upon bags of different sizes or lengths.
The bars D of the holder D are preferably provided with serrations do on their
meeting edges.
