Like letters of reference indicate like parts throughout all the figures of the
drawing.
In the drawing A represents the frame of the machine, B is an endless track on the
frame of the machine for the series of holders to ride or travel upon. C is an endless
conveyor consisting preferably of a chain for moving the holders D along the
track B. E is a sack filling and measuring device, F represents a movable section
of the track B and which is adapted to be vibrated up and down for the purpose
of shaking the sack and settling and compacting its contents. G is a reciprocating
slide or device for closing the holder after the sack is filled. H is a printing
device. K is the sewing mechanism. L is the thread cutting device and L' the
thread holding device. M is the device for discharging and delivering the filled
and sewed sacks from the machine.
The endless track B is furnished with flanges bb for the opposite side edges of

page_text: the holder D to fit against so that the holders will be properly guided in their
path by these flanges of the track. The track B has a wide slot or open space b
extending along that, portion of the track at which the holder D is open, and a
narrow slot extending along that portion of the track where the sack holder is
closed. And the guiding flanges b'b are brought close together at that portion
of the track having the narrow slot &, and where the holder is closed when passing
along such portion. The track B is provided with suitable bridges B1 spanning
the slots at suitable intervals, so as to properly support both sides or
portions of the track. At the portion of the track B extending from the
point where the filled and sewed sack is discharged to the point where the empty
sack is put into the holder; the slot borb² is of course not necessary, and the
two flanges or portions hb of the track may be here connected together by
webs B.
The endless conveyor C by which the series of holders D are moved or
conveyed-along the track 13, consists preferably of a link chain traveling around
the pulleys or sprocket wheels C C, C³ C, C, C C, the sprocket wheel C
being the driving wheel. The general path of the conveyor chain C-is along the
inner guide flange b of the track B, so that the open links of the chain are
adapted to engage the hooks d on the inner side of the holders D. At the place
or portion of the track B where the empty sacks are put into the holders, the path
of this flexible conveyor Cis deflected inward or away from the track of the
holder so that the holder will be thus automatically disengaged from the conveyor
chain and remain stationary on the track B while the sack is being put into the
same. And, after the sack is placed in the holder, the holder is pushed by hand
forward to that portion of the track where the conveyor chain again meets it, and
can thus again engage the hook d of the holder. The flexible conveyor chain C
is thus deflected at eaway from the track B by properly locating the guiding
wheels or pulleys CC of the chain. The path of the conveyor chain Cis also
deflected inward or away from the track B of the holder at the place e' where the
sack is to be filled and where the holder is stopped or remains stationary for this
purpose so that at this time also the hook of the holder will be disengaged from
the conveyor C. This second deflection of the conveyor C being effected by the
guide julleys or wheels C. For convenience and also for the purpose of giving
the holder a quicker movement from the filling position to the holder closing
position, preferably provide a supplemental conveyor chain C mounted on
pulleys C C above the track B adapted to engage a movable or hinged book d
on the holder and move the holder forward to the position where the holder is
closed.
The series of sack or bag holders D each consist, preferably of six hinged bars,
the same comprising two opposite side or long bars d2 d2 and four short or end
bars d³ ³ d³ d³. All these bars are hinged or pivoted together at their adjoining
ends so that the holder may be "pened, as shown in Fig. 12; to receive the sack
to hold it open while the sack is being filled and again open to discharge the sack
after it has been sewed, and so that the holder may be closed as shown in Fig. 13
to hold the mouth of the sack closed while it is being sewed. To automatically
open the holder it is provided with one or more, preferably two, springs d at two
of its pivots or hinges. To adapt the holder to properly and firmly grasp the
mouth edge of the bag so that the bag and its contents may be securely supported
from aud carried by the holder without any separate carrier for the bag, and to
enable the sacke to be quickly and conveniently inserted in the holder the holder
is provided at its two opposite pivotal ends with pivoted spring actuated clamping
jaws do d, and at its two long or side bars d with spring actuated clamping
jaws ad. The pivoted clamping jaw d is provided with a pin or projection d',
adapted to engage a stationary can or projection on one of the bridges B¹ over
the track B, and thus automatically open the clamping jaw d when it passes under
the bridge, as shown in Fig. 14. And the clamping jaw a is further provided
with a pivotal puwi or latch a to bold the clamping jaw d open against the

page_text: pressure of the spring d of the clamping jaw after the clamping jaw has been
opened. A spring dio holds the latch; or pawl d in position for automatically
engaging the pivoted jaw d when said jaw is opened. The clamping jaw d
consists preferably of a long sectional blade, that is to say a blade having
notches dat intervals, it is secured to a rock shaft d, which is provided with
a torsion spring d³ to hold the clamping jaw closed with the requisite pressure.
The rock shaft d is furnished with an arm or projection d adapted to engage a
cam or projection 64 on one of the bridges B₁ over the track B, and thus open
the clamping jaw d as the holder passes under the bridge. To automatically
hold the clamping jaw de in its open position after it has thus been opened, a
pivoted pawl or latch d is provided which engages a notch or projection on
the clamping jaw d and thus holds the same open. The pawl or latch dis
held in position for engaging the notch or projection d by a spring d¹8.
To put a bag in this holder, the holder being of course open, the operator first
puts the edge of the bag under one of the end clamping jaws d', then touches the
latch or pawl d and thus clamps the mouth of the bag at one point to one end
of the holder, he then takes the diametrically opposite edge of the bag and in
like manner clamps it at the opposite end of the holder by the other end
clamp d'; he then places one side edge of the mouth of the bag under one of
the long clamps de, releases the latch die and thus secures this side edge of the
bag in the holder: he then in like manner, secures the other side edge of the
bag under the other side clamp d. By this means, and in this way, the bags
may be placed in the holders with great rapidity. To increase the holding
power of the clamps d d and enable them to better support the weight of the
filled bag, the clamping faces are, preferably, provided with serrations d
The filling and measuring device E may be of any suitable construction known
to those skilled in the art, and adapted to deliver a fixed or measured quantity of
material into each bag, whether the measuring is done by weight or by bulk. The
device for this purpose illustrated in the drawing is constructed to measure by
bulk instead of by weight, and comprises a measuring chamber E' equal in
capacity to that of the bag, a discharge spout E2, delivery spout E, two
valves E E, an operating lever E, the upper valve closing completely before
the lower one begins to open.
The bag shaking device F which operates to settle and compact the material in
the bag as it is being filled, consists of, or comprises a movable section of the bag
holder track B, adapted to be automatically vibrated up and down. This up and
down vibrating movement may be communicated to the bag holder shaking.
device F by any suitable means or mechanism, but preferably as illustrated in
the drawing by revolving cams or eccentrics ff on the shafts 1, connected with
the sectional track or device F by straps or hangers f.
After the sack has been filled and duly shaken the holder D is moved along the
track B by the supplemental conveyor C¹ into position opposite the sack holder
closing slide or device G, and opposite the printing device H, the printing device
being preferably arranged directly opposite the closing device G.
The sack holder closing device G preferably consists of a transversely recipro-
cating slide furnished with anti-friction rollers g to bear against one of the long
bars d of the holder. The slide G or its stem g¹ reciprocates in suitable
guides 92 on the frame of the machine.
The printing or stamping device H may be of any suitable construction known
to those skilled in the art, that, however, which I prefer to employ is illustrated
in the drawing, and comprises a reciprocating and revolving or reversible type
carrying head, in which the type h' are mounted, the head being pivoted to a
reciprocating slide 2 working back and forth in the frame 43, and the rocking
head being provided with cam forks / adapted to engage a pin on the frame ³,
and thus half revolve or reverse the type carrying head as it reciprocates, so that
when the head reciprocates backward the face of the type will engage the inking

page_text: pad h, and when the head reciprocates forwards the face of the type will be
turned into proper position for engaging and stamping the sack. This is an old
and familiar kind of printing and stamping device, and is shown in the drawing for
convenience, although it will be obvious to those skilled in the art that other
suitable or known forms of printing devices may be used in the place of that
shown. The reciprocating slide of the printing device is operated, or preferably
operated, by the same lever G' which actuates the bag holder closing device G,
this being done by connecting the lever H¹ which operates the slide of the printing
device with the lever G¹ by a link H2. The printing operating lever H¹ is a bent
lever, and is provided at its upper end with a pivoted spring held arm H³ having a
roller H to engage the slide 3 of the printing device and push it forward. To
permit the printing head and its slide to be quickly withdrawn and thus prevent
blurring of the impression, the slide 2 is automatically withdrawn by springs ',
the roller carrying spring held arm H2 being adapted to pass under the slide the
moment the impression is made. As the arm H2 is pivoted to the lever H, this
permits the lever to be swung back into position at the rear of the slide 2 to
repeat the operation on the next bag. The spring H returns the pivoted arm H³
to position after it passes out from beneath the slide /².
The bag holder closing slide G is reciprocated by the treadle or lever G¹
through the intermediate bent lever G2 and connecting links G3 G', the connecting
link G being provided with a spring Go to retract the slide G and lever G', and
also the printer operating lever H. A spring hook or pawl g, engaging the
lever G', serves to hold the slide G closed until the holder passes."
The sewing device K may be of any suitable construction, but preferably com-
prises, as shown in the drawing, a frame arm or bracket K¹ attached to the frame
of the machine, a reciprocating needle K, a continuously revolving looper K³,
and suitable means for reciprocating the needle and revolving the looper. This
operating mechanism may be, as shown in the drawing, an upright shaft K
carrying a gear K³, which is provided with a crank pin K connected to a
pitman K', which is connected at its other end to a crank arm K8 on a crank
shaft K. This crank shaft K has another arm K which is connected by a
pivoted link K to the slide or bar K2 to which the needle is attached. And for
operating the looper the upright shaft K is provided with a gear K¹³ which
meshes with an intermediate gear K¼ that meshes with a gear K on the
revolving shaft K18 of the looper.
The thread cutting device or mechanism L consists of two reciprocating knives,
and the thread holding device L' consists of two reciprocating jaws between which
the severed end of the thread is clamped or held after being severed by the
knives. The two knives L L and the two thread holding jaws L L are
preferably, one of each pair, connected to the same reciprocating spring actuated
slide 1. Each of the sliding jaws L2 is furnished with a pin or roller L³ pro-
jecting in the path of the bolder in the track B, so that the instant each holder
passes the projection L³, the sliding bars L2 L2 carrying the knives and thread
holding jaws will be actuated or closed against each other by their springs L* L*,
and thus automatically sever the thread and grasp or hold the free end thereof.
The device M for automatically discharging or delivering the filled and sewed
sack from the machine, consists preferably of an inclined, revolving, spring
supported platform, so that, when the filled bag drops onto it, it will by the weight
and impulse of the bag automatically be swung around and thus discharge or
deliver the bag out of the way. This inclined and revolving platform Mis
adapted to rock or rotate and also reciprocate up and down on a stationary
inclined shaft M', and is supported by a spring M2 which bears at one end against
a cellar M³ fixed to the shaft M', and the other end against a sleeve M to which
the platform M is connected by ros M. The spring also acts torsionally, being
connected at one end to the sleeve and at the other end to the collar, and thus"
serves to automatically return the platform to position after swinging outward to

page_text: discharge a sack. An arm M, secured to one of the rods M serves by striking
against a brace of the frame to limit the torsionally inward throw of the spring.
N is the main driving shaft of the machine, and N is the driving pulley.
Motion may be communicated from the driving shaft N to the shaft C which
carries the sprocket wheel C that drives the endless conveyor chain C by any
suitable means or mechanism; but it is preferably done, as illustrated in the
drawing, by a gear n on the shaft N meshing with a gear n' on the short shaft n²,
said short shaft having a spracket wheel which communicates motion by a
chain to the sprocket wheel x on a counter shaft n, which cuter shaft
carries a gear meshing with the gear n on the short shaft n, which is
provided with a bevel gear a that meshes with a bevel gear w" on the shift C',
to which said sprocket wheel C is secured.
Motion may be communicated to the supplemental carrier chain C¹ by any
suitable means or mechanism, but preferably as illustrated in the drawing by
providing the shaft n with a sprocket wheel a" which communicates motion by a
chain to a sprocket wheel on shaft a to which the driving pulley C of the
supplemental carrier C is secured.
Motion may be communicated to the shaft 1 which actuates the shaker F by
any suitable means, but preferably as illustrated in the drawing by providing the
shaft with a sprocket wheel " by which motion is communicated through a
chain n to a sprocket wheel n18 on a clutch sleeve 2 loose on the shaft f, said
clutch sleeve being engaged by an opposing clutch sleeve which rotates with
the shaft, so that when the operator by means of the clutch rod pulls the
clutch sleeve into engagement with the clutch sleeve the shaft will be
rotated. It should here be observed that the pulley or wheel C of the supple-
mental carrier chain C which is on this shaft f¹ is a loose or idle pulley on the
shaft, so that the carrier chain C¹ can receive no motion from the shaft but only
from its driving shaft n, as before explained. The other shaker operating
shaft is actuated from its companion shaft / by means of a chain engaging
sprocket wheels on said shaft ff.
Motion may be communicated to the sewing device or mechanism or to the
upright shaft K₁ thereof by any suitable means, but preferably as illustrated in
the drawing by a bevel gear K on said shaft K which meshes with a bevel
gear on a clutch sleeve P which is thrown into gear with the driving shaft N
by a sliding clutch P, said sliding clutch P being automatically operated by a
sliding arm p projecting into the track B in the path of the bag holder D, and
which sliding bar p is provided with an arm p¹ that engages the sliding clutch P3
which thus throws it into engagement with the clutch sleeve P. A spring p³
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 D is carried past such clutch
operating arm p.
The operation is as follows: At the station X' where the conveyor chain C is
out of engagement with the holders D the bags are placed in the holders one after
another by the operator. After the operator has put a bag into one of the holders,
he pushes the holder forward along the track 13 to the point where its hook d wiil
engage the conveyor chain. The conveyor chain then carries the holder along the
endless track B to the point where the conveyor chain C is deflected away from
the track B, at which point the conveyor chain is automatically disengaged from
the holder, thus leaving the holder stationary on the track B at or near the filling
station. The operator at the filling station then pushes the holder forward under
the spout of the filling and measuring device. The operator then moves the valve
operating lever of the filling mechanism so that the material then runs into the
sack or bag from the measuring chamber. The holder is now resting on the
shaker F, on the up and down movable portion of the track B, and the operator
now moves the clutch operating rod which sets the shaker F into vibration. After
the sack is sufficiently shaken the operator throws the shaker out of gear and with
his hand lifts the pivoted hook d on the holder D into engagement, with th

page_text: supplemental carrier chain C¹ and the holder with the filled bag is thereby moved
forward into position opposite the sack holder closing device 'G and the printing
device H; the hook d being automatically disengaged from the supplemental
carrier chain C at the point where said carrier chain turns upward or around its
pulley or sprocket wheel. The operator. now depressing the treadle or lever G¹,
actuates the closure slide G and closes the holder, and at the same time actuates
the printer slide and thus stamps the necessary impressions or marks upon the bag.
The bolder D is now again brought into engagement with the endless conveyor C,
and is by it conveyed past the sewing device K the operating clutch of which is
thrown into gear by the engagement of the holder with the projecting arm p
which operates the clutch, and as the holder passes the thread cutting and holding
device LL' the thread is automatically severed and its free end grasped and held.
As the holder passes along the endless track the arms d' and engage the cams
or projections 34 on the bridges B B and thus automatically release the
clamping jaws d d thus permitting the bag to drop out of the holder down upon
the discharger M, and at the same time the springs on the holder throw the
holder open as it has now reached the point where the guide flange b of the
track B is widely separated from the carrier C so that the springs d can throw
the holder open. It should also be observed that when the clamping jaws d³ de
are automatically thrown open by passing under the bridges B₁ B' they are locked
or held in this open position by the latches or pawls d8 d16 until these latches or
pawls are again released by the operator when he puts another bag into the holder.
The conveyor C carries the holder back to the station where the bags are inserted,
when the operation is repeated successively with each and all of the holders of the
series.
When the holder D is closed by the slide G the short bars d³ are brought into
line with the long bars d², and this act of closing the holder thus throws the
hook d20 on the front short bar d³ adjacent to the conveyor chain C into engagement
with the conveyor chain so that the moment the holder is closed by the slide G it
will be caught by the chain C and carried forward along the track B past the
sewing device. The holder closing slide G holds the holder closed by reason of
the spring pawl or hook 93 until the holder is advanced by the conveyor C into the
contracted part of the track B where the flanges bb converge to the width of the
holder when it is closed, so that said flanges of the track will then keep the holder
closed.
