Improvements in Machines for Filling Sacks, Sewing the Mouths
thereof, and Printing or Marking such Sacks.
I, ARTHUR THOMAS TIMEWELL, of 3236, Lake Park Avenue, in the City of
Chicago, County of Cook and State of Illinois, United States of America, Gentle-
man, do hereby declare the nature of this invention and in what manner the same is
to be performed, to be particularly described and ascertained in and by the
following statement:
-
My invention relates to improvements in machines for filling sacks or bags with
various materials and sewing up the mouths of such sacks or bags after they are
filled.
My invention consists, in connection with a bag filling mechanism, a sewing
mechanism, a series of opening and closing movable sack holders, an endless
recurring track upon which the holders travel to convey the sacks or bags from the
filling station to the sewing station and to the discharging and receiving stations,
and an up and down movable bag shaking device engaging the sack holder so as
to shake the sack from its mouth or top edge, of a movable bumper or support
adapted to strike or engage the sack at its lower end in order that the material
in the sack may be settled, compacted or compressed simultaneously from both the
upper and lower end of the bag. Another feature of my invention consists in
combining with the movable bag holders, the track upon which they travel, the
chain or other mechanism for propelling the holders along the track, and the sew-
ing device or mechanism, a thread holding device provided with a feed device or
mechanism for the thread, which feed device is set in operation by the sewing
mechanism itself, or simultaneously with the sewing mechanism, and a friction
clutch or equivalent mechanism for gradually setting in operation or communi-
cating motion to the sewing mechanism, and of having it positively geared to
start and stop at fixed intervals in respect to the movement of the bag holder along
its track, and in respect to the opening and closing of the thread holder, is obviated.
By this means I materially add to the durability of the machine, and also cause
it to run more smoothly and easily and without shock or strain to the sewing
mechanism. Another feature of my invention consists, in connection with the
filling mechanism and sewing mechanism, the series of opening and closing sack
holders and the track and mechanism for moving them along the track, in provid-
ing a short guide or guard along the track which is engaged by a pin projecting
from each of the holders near the front end thereof, for the purpose of compressing
or keeping the holder closed at its front end until its rear end emerges from the
guide flanges of the track which hold the holder closed, thus preventing the front
end of the holder from slightly opening and letting the filled sack down before
fully reaching the position for discharging the sack. My invention also consists
n the novel construction of parts and devices, and in the novel combinations of
parts and devices herein shown and described and more particularly specified in
he claims.
In the accompanying drawing, forming a part of this specification, and in which

page_text: similar letters of reference indicate like parts throughout all the figures, I have
shown one construction, and which I believe to be the best construction of machine
now known to me for reducing my invention to practice.

In the drawing A represents the frame of the machine, and A¹ are wheels or
casters upon which the frame is mounted to adapt it to be moved about the dock
or warehouse where the machine is used to bring it in position for connection with
various elevator spouts or other spouts or bins from which the material to be sacked
is to be delivered to the machine. A² is an electric or other motor, mounted on
the movable frame of the machine for supplying the power necessary for driving
it in the different positions where it may be placed. B is an endless recurring
track on the frame of the machine, along which the series of opening and closing
movable sack holders D 1) are moved or conveyed from the sack filling and
measuring device E, shaker F and bumper F1 to the sack closing device G and
printing device H, thence to the sewing device K, thence to the discharging
device M, thence to the sack receiving station X and finally back again to the
filling device. Along this track B the movable sack holders are conveyed, prefer-
ably by a number of separate conveyors or moving devices adapted to engage the
holders, the same being, preferably, a power driven endless conveyor or chain C,
a supplemental power driven endless conveyor or chain C, and a hand-operated
conveyor or wheel C². The track B is furnished with side guides or flanges bb
projecting upward from the track and adapted to engage the two opposite side
edges of the holders and thus keep the same closed, these guides or flanges having
a space between them equal to the width of the holder when it is closed. The
track B is also furnished with a wide slot or open space b¹, extending from the
sack receiving station X where the holder is open to the device for closing the

page_text: holder, and with a narrow slot 62, extending from the position where the holder
is closed to the position where it is again opened to discharge the filled and sewed
sack. The guides or flanges bb preferably extend only part way of the track B,
that is to say along that portion of the track where the holder is held closed by said
guides or flanges, and along the portion of the track at the sack receiving station X
to guide the movement of the open holder along the track when it is being moved
by the hand of the operator, who puts the sack into the holder, from the point
where it is released by the conveyor C to the point where it is again engaged by
the conveyor C³. By thus making the track B plain or without guides or flanges
for the holder at the curved portions of said track, I obviate all danger of accident
from the holders binding on the guides as they are being conveyed, or from one
holder injuriously jambing against another.
The conveyor C by which the series of holders D are moved along the track B
from the holder closing device G to the sack receiving station X, consists, prefer-
ably, of an endless link chain, travelling around the driving wheel or pulley C³,
the large sprocket wheel or pulley C at the right hand end of the machine, and the
intermediate or idle pulleys C5, C6, C7, Cs. Each of the holders D is provided on its
inner side near its front end with hooks or projections dda, adapted to engage the
links of the chain conveyor C, along that portion of the track where the path of
the chain C coincides with the path of the holder or track B.
From the sack filling position to the sack closing position the series of holders D
are conveyed or moved along the track B by the supplemental conveyor C¹, which
is also preferably an endless link chain, and travels upon the sprocket wheels or
pulleys CC, located above the track B, and the links of which are engaged by a
hinged or pivoted hook d with which each of the holders D is provided at or near
its front end, and which hook the operator lifts into engagement with the chain C¹
after the sack has been filled and the material settled or compacted therein by the
shaker F and bumper F¹.
To hold the hook or projection da in proper engagement with the chain or con-
veyor C at the curved portion of the track, or where the chain C passes around the
pulley C, I provide a guide or guard B', extending around the outer half circle
of the pulley C, there being a sufficient slot or space between this curved guard BI
and the conveyor chain on the pulley C to accommodate or give room for the hook
or projection 2 on the sack holder D.
The supplemental hand operated conveyor C2 is preferably made in the form of
a wheel, and it is furnished with a hook, pin or projection c on its periphery which
engages the pin or projection on the holder, and thus convey the holder around
to a position near the sack filling station. To keep the pin of the holder in
engagement with the pin c on the conveyor C, a guard B2, extending around the
outer periphery of the wheel C³ is provided.
Each of the holders D comprises two opposite side or long bars D¹ D¹, and four
short or end bars D², D2, D2, D2, the six bars being hinged together at their ends so
that the holder may be opened and closed. One or more springs d* at one or more
of the pivots of the holder serves to automatically throw it open. Each of the
holders is provided with clamping jaws do do at its opposite ends, and with clamp-
ing jaws de de at its side. The pivoted clamping jaws do do are each provided with
friction rollers d', adapted to engage respectively the stationary cams or projec-
tions 63 overhanging the track and thus automatically open these clamping jaws
when the holder reaches the position for discharging the filled and sewed sack.
Each of the clamping jaws do is also provided with a pivoted pawl or latch d³ to
hold the clamping jaw open against the pressure of the spring by which the
clamping jaw is eu closed. The latch 8 is furnished with a spring d¹o to hold it
in position for engaging the clamping jaw do when it is open. Each of the clamp-
ing jaws de consist of a long sectional blade having notches d¹¹ at intervals, secured
to a rock shaft.d2 which has a torsion spring d¹³ to hold the clamping jaw closed.
Each of the rocks shafts d¹ is furnished with an inwardly projecting arm d¹ by

page_text: which the clamping jaw is opened and which is adapted to engage a stationary cam
or projection 64 overhanging the track B and thus open the clamping jaw 66 when
the holder reaches the position for discharging the filled and sewed sack. A
pivoted pawl or latch d¹ engages a notch or projection d on the rock shaft of the
clamping jaw to hold it open, the pawl or latch die being provided with a spring 18.
To prevent the holder from beginning to open at its front end before reaching
the position for discharging the sack, I provide a short guard or guide B³ over-
hanging the track B, and which is engaged by a pin or projection 20 near the
front end of the holder. When the pin d20 on the holder passes the guide or
guard 13 the rear end of the holder simultaneously emerges from between the side
guides b, b of the track B, so that the holder is free to be thrown open by its
springs d d simultaneously at both ends. As long as the rear half or more of
the holder remains between the side guides bb of the track B, these side guides
alone will effectually operate to keep the holder closed; and when the holder
advances somewhat further along the track B the pin d20 near the front end of
the holder will engage the short guide or guard B³, so that the holder will now
.be held closed at both ends, at the rear end by the side guides bb and at the front
end by the short guide B³ engaging the pin 20.
The pin or projection d on the holder which first engages the chain carrier C is
located on the front short arm 13 of the holder adjacent to the chain carrier C,
so that when the holder is shut from its open position to its closed position, the
mere act of thus closing the holder will throw this pin or projection d. into
engagement with the conveyor C and thus cause the holder to begin to move
forward the moment it is closed. As the holder is thus advanced along the con-
veyor C its second pin or projection d², which is located on the long side bar D¹
of the. holder, comes also into engagement with the conveyor chain C. The
moment the holder reaches the sack discharging position and is allowed to be
thrown open by having passed the side guides bb and the short guard B3, the pin
or hook d on the short arm D2 of the holder is automatically withdrawn from the
conveyor C by the mere act of the holder opening, so that only one of the pins or
hooks, viz: the pin or hook d³, will pass between the curved guard B¹ and the
conveyor chain C as it passes around the pulley C. This prevents any danger
of interference or binding, as the holder is conveyed around the curved portion
of the track. A pin or projection 21 on the holder prevents the holder from
swinging under the line of the carrier chain or the pulley C4 by engaging the
outer surface of the curved guard B¹.
.
As the holder D is in its open position when it is moved along the track B into
engagement with the carrier wheel C2, it is only the pin 2 on the side bar D¹
that engages the projection c on the carrier wheel C. And the pin d21 in con-
nection with the curved guard B2 performs the same function at this end of the
anachine that it does in connection with the curved guard B' at the other end of
the.machine.
E. is the filling device or spout through or by which the grain or other material
is filled into the sack.
The measuring device by which the quantity of material supplied to each sack
is gauged or determined may be of any suitable kind, and operated to measure
either by weight or bulk. I prefer however to employ a bulk measuring device,
as shown in the drawings. It comprises a measuring chamber E¹, equal in
capacity.to.that. of the bag; a receiving spout E3 and two valves E3 E4, the upper
one separating. the measuring. chamber from the receiving spout and the lower
one separating the measuring chamber from the filling, spout E. These valves
are alternately opened and closed by a lever E³.
The shaker E: which operates to shake the sack from its mouth or upper edge
by moving the sack holder itself up and down, is vibrated by revolving cams ff
on the shafts f¹ fi through the connecting straps or hangers f³ f².
The bumper F against which the lower end of the sack strikes as it is being
shook or lifted up and down by the shaker F, consists, preferably, of an up and

page_text: The
down movable platform or support. It reciprocates up and down on a suitable
guide the bumper being preferably provided with anti-friction wheels or
rollers F3 to engage the upright guide F. The bumper F is raised to any
required height and then locked or fixed in this position, so that the bottom of
the bag will properly strike against it as it is being filled from the spout E and
moved up and down by the shaker F. It is thus fixed or locked in position by a
latch or locking pin F actuated by a spring F5, engaging one of a series of holes Fe
in the upright guide F. It is lifted to the required height by a chain or con-
nection F, which passes over the pulley FS on the sleeve F. A weight F10 is
connected to the chain 17, which partially compensates for the weight of the
bumper and enables it to be more easily lifted into position for operation.
bumper F is provided with a trip F, which is engaged by the bottom of the sack,
so that the weight of the sack and its contents against this trip as the bumper is
being raised up, will move this trip and thus release the spring-actuated latch or
locking pin F, and thus permit it to engage one of the holes in the guide F and
thereby prevent further movement of the bumper F¹. As the trip lever FIl is
thus operated by the weight itself of the sack being filled, the bumper. will be
automatically stopped or fixed in proper position for properly bumping or engag
ing the sack whatever may be the precise length of the sack or the precise point
at which the mouth of the sack is clamped in the holder D. This feature is one
of value in the practical operation of the machine, as the sacks always vary more
or less in length, and because even if the sacks were all of them of the same length
the operator would unavoidably fix the mouths of the bags in the holders at more
or less varying points.
Motion is communicated to the shafts f¹ f¹ by which the shaker F is operated,
from the shaft through the bevel gears f³ f³ thereon, engaging bevel gears fift
on the shaker operating shaft fi ft. The shaft f has fixed to it a clutch f and it
is thrown in gear with the shaft n by a clutch sleeve fo, which is operated by a
clutch rod through the lever fs and a handle bar or pull rod f³. The clutch
rod is also furnished with an arm f10 that operates a sliding friction clutch
sleeve f, which engages the friction clutch sleeve F9 to which the pulley or
sprocket wheel F8 of the bumper operating chain is secured. As the clutch fo fo
is a toothed clutch, and the clutch ff a friction clutch, the teeth of the
clutch f f will permit, after coming into engagement with each other, a sufficient
further movement of the clutch rod f to bring the parts of the friction clutch
into operative engagement. It will thus be seen that the operator by the first
movement of the clutch rod f throws the shaker F into operation, and that the
further movement of the same clutch rod throws the friction clutch sleeves fil, fº,
into engagement with each other and thus causes the bumper to be raised up
against the lower end of the bag being filled until the weight of the contents of
the bag against the trip F" causes the trip to move and thus releases the latch or
locking pin F when the bumper will be fixed thereby to the stationary guide Fº.
As power is communicated to the bumper raising mechanism through a friction
clutch controlled by the clutch lever in the hand of the operator, the operator can,
by exerting greater or less force upon the clutch lever cause the bumper to begin
to be raised at any time desired as he feels the weight of the contents of the bag
being filled. And as the bumper is being lifted the operator can, at any moment
desired allow the weight of the bag and its contents to overcome the friction between
the faces of the friction clutch f F9. By this means, in connection with the
trip F" the position of the bumper is always under the control of the operator.
After the bag has been filled and its contents sufficiently settled and compacted by.
the operation of the shaker from above and the bumper from below, the operator
moves the clutch lever and the clutch rod in the opposite direction and thus throws
the shaker driving shaft fout of gear, and an arm f12 on the clutch rod f
engages a lever fl³, that operates a sliding bar f furnished with pins fi6 fi6,
that fit in inclined slots or cams f" f17 on the stationary frame of the machine,
so that this bar engaging the catch or locking pin F, will thus retract the same

page_text: and permit the bumper to descend by its own weight. The counterbalance F10 is
made somewhat lighter than the bumper, so that the bumper will descend by its
own weight after its locking pin is released from the guide F2.
The closer G or device for closing the track holder 1), consists, preferably, of a
reciprocating slide furnished with anti-friction rollers g to bear against one of
the long bars of the holder. The slide G is reciprocated in its guides g³ on
the frame of the machine by means of a rack g', which is engaged by a gear y³
on the shaft g, which is operated by a chain 95 passing around and secured by
a sprocket wheel g6, and which chain is attached to and operated by a treadle or
lever G. A spring g', preferably a torsional spring, surrounding the shaft g
retracts the closing device G after the holder is closed and is conveyed beyond the
closer and between the two side guides 66 of the track B.
Owing to the rough, coarse, fibrous fabric of which sacks or bags are usually
made, and to the more or less irregular surface presented to the printing device
by the sack, and the more or less irregular and yielding nature of the support
afforded by the contents of the filled bag against the pressure of the printing
device, I have found that it adds greatly to the success and efficiency of the
machine, as a whole, to combine with the other parts a printing device that operates
in the nature of a stencil. The stencil printing device of the machine comprises
a stencil H, mounted upon a reciprocating and slightly rocking head or holder h
which is carried by and pivoted to a reciprocating shaft carrying the ink
applying brush H¹. The brush shaft h¹ reciprocates bodily back and forth in a
guide h. The stencil head or holder his furnished with pins h³ that reciprocates
in a guide +. A reciprocating slide H2 engaging the brush carrying shaft ¹
moves said shaft and the stencil holder or head h backward and forward in their
respective guides h' h*. The reciprocating slide H³ is furnished with a curvel
slot at is end where it engages the brush shaft h. And the brush shaft 1.
is provided with arms ho ho, having slots h that engage pins he on the slide H².
Springs H are inserted between the slide H2 and the stationary frame or box H,
to which the plates H6 are secured. The guides h³ are formed in or secured to
the stationary plates H6. When the slide H2 is reciprocated or moved forward it
pushes forward the brush shaft and the stencil holder h until the stencil is
pressed against the bag X1, as shown in Figure 18, and until the brush shaft h¹
reaches the limit of its former movement and rests in the curved extremity of the
slot 2 as shown in Fig. 18 and 18, this being done by reason of the curve or
shoulder in the slot 5 in the slide H³. The further forward movement of the
slide H causes the brush shaft h, which now rests in the curved extremity of the
guide or slot 2 and is thus prevented from further forward movement, to rotate
on its axis by reason of the arm on said brush shaft h¹ engaging the pin 8 on
said slide H2, thus swinging or wiping the ink carrying brush over the stencil and
marking the bag by reason of the rotation of the brush shaft. The wiping
movement of the brush over the stencil is repeated when the brush and its shaft
makes its backward oscillation on the return movement of the slide H². By
this means I am enabled to print or mark upon the bag the requisite characters
or data plainly and distinctly. The slide H2 is operated by a lever 19 furnished
with a spring-held or yielding pivoted arm h, and which lever is connected to an
arm G2 on the shaft G3 of the treadle G¹ by a connecting link h¹¹.
The sewing device or mechanism K comprises, preferably, a frame or arm K¹
attached to the frame A at one side of the track B and overhanging said track, a
reciprocating needle K³, and a revolving looper K³. The needle is reciprocated by
an eccentric or cam K' on the shaft K³, through the pitman rod K, which is con-
nected to an arm K7 on the rock shaft K8 which has another arm K³ connected by
a link with the slide K" to which the needle K² is attached. The looper K³
is revolved by a gear K12 on the shaft Ks, through the intermediate gear K13 that
meshes with the gear K₁ on the shaft K15 of the looper. The shaft K5 of the sewing
device is driven from the shaft N through a friction clutch K K", the sliding
clutch sleeve K17 being on the shaft K18 which has a bevel gear K, which meshes

page_text: with a bevel gear Ko on the shaft K³. The clutch sleeve K" is operated to put the sew-
ing mechanism in gear by a slide K2 which projects in the path of the holder D as it
moves along the track B. This slide operates the clutch sleeve through suitable con-
necting mechanism, the same consisting preferably of an arm K in the slide K21, a
connecting link K23 and a lever K2 which is pivoted to a collar K on the clutch
sleeve K. A spring K26 moves the clutch sleeve K" in the opposite direction to
throw the sewing mechanism out of gear when the holder D passes beyond the
slide K. A friction brake K27 engages the rear face of the bevel gear Ki⁹ to stop
the motion or momentum of the sewing mechanism as soon as the clutch K" is
thrown out of gear. This friction brake is connected to the clutch operating lever
by the link K³, so that the brake is released the moment the clutch is thrown in
gear.
K2 is the presser foot, its stem K2 is furnished with a spring K.
The thread cutter L L consists of a pair of reciprocating knives, and the thread
holder consists of a shoe or jaw L¹ and a revolvable thread feed wheel L² which is
geared to the sewing mechanism so as to revolve and permit the thread to feed as
long as the sewing mechanism is in gear, this causes the thread or chain to be fed
or taken up as long as the sewing mechanism is running and prevents entangling of
the thread with the looper or other parts, and obviates danger of breaking the
thread or needle. The thread outter knives and the thread holder devices are
mounted upon reciprocating slides L³ L³, which are furnished with pins or
rollers LL, which engage the holder D, so that the holder as it passes along will
separate these slides and permit them to be closed by their springs L L when
.the holder passes. The thread holding shoe or jaw L' is supported on independent
springs L6 on the slide L³ so that it may have a yielding pressure against the thread.
holder feeding roller L. In order to prevent the slide K" from closing or moving
back to throw the sewing mechanism out of gear until the thread cutter and holder
slides L³ L³ can close, I provide the slide L3 with a projection L7 that engages the
arm K on the slide K21 and thus prevents said slide K2 closing in advance of the
slide L. Any suitable mechanism may be employed to gear the thread feeding
and holding roller L³ to or with the sewing mechanism. The means
prefer to employ is shown in the drawing and consists of an eccentric
on the sewing mechanism driving shaft K³, which through a pitman
or connecting link L³ operates a lever L' carrying a pawl L, that engages a
ratchet wheel L on the shaft L12 of the roller L². L¹³ is a locking pawl also
engaging this ratchet L. By this means the requisite feed movement may be com-
municated to the thread or chain stitch holding and feeding roller L³.
The filled and sewed sack discharging device M consists, preferably, of an inclined,
revolving spring-supported platform. This platform M is attached to a sliding
and rotatable sleeve M', on the inclined shaft M2, the sleeve being supported by a
spiral spring M³ surrounding the inclined shaft. A spiral groove m in the sleeve
causes it to rotate as it reciprocates downward on the rod under the weight of the
sack when it is dropped upon it by the opening of the holder D. When the spring
retracts it returns the platform to another position to receive another sack. Mis
an arm to guide or hold the upper end of the sack until it is swung around and dis-
charged.
N is the main driving shaft of the machine. Motion is communicated to it from..
the motor A2 on the frame of the machine through the belts N1N2, and pulleys N³
N4 N5 N° and N, pulley No being a loose pulley on the driving shaft and the.
pulley N the driving pulley. Motion is communicated from the driving pulley to.
the shaft C19 of the driving pulley C³ of the chain conveyor C by means of the gear n
on the driving shaft N meshing with the gear n¹ on the counter shaft n², which
carries a small gear n³ that meshes with a gear n' on the shaft n³, which carries a
bevel gear no that meshes with a bevel gear n² on the shaft C19 of said conveyor
5 driving pulley C³.
Motion is communicated from the shaft n² to the shaft n¹² carrying the clutch f

page_text: for driving the shaker operating shaft f by means of a bevel gear n¹³ on said
shaft n, which meshes with a bevel gear n¹ on said shaft n¹. One of the pulleys C
of the supplemental conveyor C' is secured to this same counter shaft n3 and is thus
driven continuously.
Motion is communicated to the sewing mechanism K, as before described, through
the friction clutch K16 K one member of which is carried by the driving shaft N.
The supplemental conveyor or wheel C is preferably operated by hand, this being
conveniently done by means of a shaft C, carrying a bevel gear C" that engages a
bevel gear C12 on the shaft of the conveyor C. It is operated by a crank C¹³.
