SPECIFICATION forming part of Letters Patent No. 562,438, dated June 23, 1896.

Application filed March 15,1895, strain). 541,865. (NomodeL) To all whom it may concern: i

a citizen of the United States, residing in Ohicago, in the county of Cook and State of Illinois,have invented a new and useful Improvement in Machines for Filling and Sewing Sacks, of which the following is a specification. I

My invention relates to improvements in machines for filling sacks or bags and sew ing up the mouths of the same after they are filled. 1 I l My present invention is an improvement upon the sack filling and sewing machine shown and described in my application, Serial No. 524,164.

My present improvement consists in combining with the series of sack holders, filling mechanism, and sewing device, an endless track along which the sack-holders are conveyed first to the filling mechanism and then to the sewing device, so that the holders are not discharged from the machine and do not require to be replaced in the machine.

It also consists in the combination of these parts with a device for automatically printing desired marks or data upon the sack. In my new machine I also convey the sack along solely by the holders, and thus materially simplify the machine by entirely dispensing with the carriers which I heretofore employed for supporting and carrying the sack.

It also consists in providing the track for the holder with a movable section adapted to be vibrated up and down, and thus accomplishing the shaking of the sack from the holder, that is to say, from the mouth or top taken together, are a side elevation of a ma- Y chine embodying my invention. Be it known that I, ARTHUR T. TIMEWELL, 1

Fig.

M is the device for discharging and delivering the filled and sewed sacks from the machine.

The endless track B is furnished with flanges b b for the opposite side edges of the holders 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 1) extending along that portion of the track at which the holder D is open, and a narrow slot b extending along that portion of the track where the sackholder is closed, and the guiding-flanges b b are brought close together at that portion of the track having the narrow slot 19 and where the holder is closed when passing along such portion. The track B is provided with suitable bridges B, spanning the slots 1) b 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 1) or b is of course not necessary, and the two flanges or portions 1) b of the track may be here connected together by webs 5 The endless conveyer 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 sprocketwheels 0 C C O O C C, the sprocket-wheel C being the driving-wheel. The general path of the conveyer-chain O 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 sides of the holders D. At the place or portion of the track 13 where the empty sacks are put into the holders the path of this flexible conveyer C is deflected inward or away from the track of the holder, so that the holder will be thus automatically disengaged from the conveyer-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 conveyer-chain again meets it, and can thus again engage the hook d of the holder. The flexible conveyer-chain C is thus deflected at c away from the track B by properly locating the guiding wheels or pulleys C C of the chain. The path of the conveyer-chain C is also deflected inward or away from the track 13 of the holder at the place a where the sack is to be filled and where the holder is stopped or remains sta tionary for this purpose, so that at this time also the hook of the holder will be disengaged from the conveyer 0, this second deflection of the conveyer 0 being eflfected by the guide pulleys 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, I preferably provide a supplemental conveyer-chain C, mounted on pulleys C 0 above the track B,

adapted to engage a movable or hinged hook I 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 d d and four 'short or end bars 01 d 61 (1 All these bars are hinged or pivoted together at their adjoining ends, so that the holder may be opened, 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,preferablytwo,springs cl 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 and carried by the holder without any separate carrier for the bag, and to enable the sacks to be quickly and convenientlyinserted in the holder, the holder is provided at its two opposite pivotal ends with pivoted spring-actuated clamping-jaws d d, and at its two long or side bars d with springactuated clamping-jaws cl d. The pivoted clampin g-j aw d is provided with a pin or proj ection d adapted to engage a stationary cam or projection 12 on one of the bridges 13 over the track 13, and thus automatically open the clamping-jaw (1 when it passes under the bridge and shown in Fig. let; and the clamping-jaw d is further provided with a pivotal pawl or latch d to hold the clamping-jaw (Z open against the pressure of the spring cl of the clamping-jaw after the clamping-jaw has been opened. A spring (2 holds the latch or pawl d in position for automatically engaging the pivoted jaw (1 when said jaw is opened. The clamping-jaw (1 consists, preferably, of a long sectional blade, that is to say, a blade having notches (Z at intervals. It is secured to a rock-shaft (Z which is provided with a torsion'spring (Z to hold the clamping-jaw closed with the requisite pressure. The rockshaft 61 is furnished with an arm or projection d, adapted to engage a cam or projection 12 on one of the bridges B over the track B, and thus open the clamping-j aw d as the holder passes under said bridge. To automatically hold the clamping-j aw d in its open position after it has thus been opened, a pivoted pawl or latch al is provided, which ongages a notch or projection cl on the clamping-jaw d, and thus holds the same open. The pawl or latch (Z is held in position for engaging the notch or projection (Z by a spring (Z 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 cl, releases the latch d, 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 (Z 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 drawings iscon struct-ed 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 E 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-shakin g 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 drawings, by revolving cams or eccentrics f f on the shafts f, 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 conveyer G into position opposite the sack-holder-elosin g 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-reciprocating slide furnished with antifriction-rollers g to bear against one of the long bars (1 of the holder. The slide G or its stem g reciprocates in suitable guides g on the frame of the machine.

The printing or stamping device II may be of any suitable construction known to those skilled in the art. That, however, which I prefer to employ is illustrated in the drawings, and comprises a reciprocating and revolving or reversible type-carrying head 72 in which the type 7b are mounted, the head being pivoted to a reciprocating slide 7L2, working back and forth in the frame 7F, and the rocking head being provided with cam-forks h adapted to engage pins 771 on the frame h and thus half revolve or reverse the type-carryin g head as it reciprocates, so that when the head reciprocates backward the face of the type will engage the inking-pad h, and when the head reciprocates forward 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 drawings 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 H which operates the slide of the printing device with the lever G by a link H The printer-operating lever H is a bent lever, and is provided at its upper end with a pivoted springheld arm H having a roller H to engage the slide 72. 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 7L is automatically withdrawn by springs 7L7, the roller-carrying spring-held arm I-l being adapted to pass under the slide the moment the impression is made. As the arm H is pivoted to the lever H, this permits the lever to be swung back into position at the rear of the slide 7L2 to repeat the operation on the next bag. The spring H returns the pivoted arm 11 to position after it passes out from beneath the slide 7L2.

. The bag-holder-closing slide G is reciprocated by the treadle or lever G through the intermediate bent lever G and connectinglinks G G, the connecting-link G being provided with a spring G to retract the slide G and lever G, and also the printer-operating lever 11. A spring hook or pawl 9 engaging the lever G, serves to hold the slide G closed until the holder passes.

The sewing device K may be of any suit able construction, but preferc bly comprises, as shown in the drawings, a frame arm or bracket K, attached to the frame of the machine, a reciprocating needle K a continu ously-revolving looper K and suitable means for reciprocating the needle and revolving the looper. This operating mechanism may be, as shown in the drawings, an upright shaft K, carrying a gear K which is provided with a crank-pin K, connected to a pitman K which is connected at its other end to a crankarm K 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 K to which the needle is attached, and for operating the looper the upright shaft K is provided with a gear K which meshes with an intermediate gear K that meshes with a gear K? 011 the revolving shaft K of the looper. r

The thread-cutting device or mechanism L consists of two reciprocating knives, andthe thread-holding device L consists of two .re

ciprocating 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 L Each of the sliding jaws L is furnished with a pin or roller L projecting in the path of the holder in the track 13, so that the instant each holder passes the projection L the sliding bars L L 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 autom atically dischargin or delivering the filled and sewed sack from the machine consists, preferably, of an i11- clined, 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 M is adapted to rock or rotate and also reciprocate up and down on a stationary inclined shaft M, and is supported by a spring M which bears at one end against a collar M fixed to the shaft M, and the other end against a sleeve M to which the platform M is connected by rods M. The spring also acts torsionally, being connected at one end to the sleeve and at the other to the collar, and thus serves to automatically return the platform to position after swinging outward to 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 0 which carries the sprocket-wheel 0 that drives the endless conveyor-chain G by any suitable means or mechanism; but it is preferably done, as illustrated in the drawings, by a gear 02, on the shaft N meshing with a gear 7?. on the short shaft if, said short shaft having a sprocket-wheel n" which communicates motion by a chain a to the sprocket-wheel n on a counter-shaft a, which counter-shaft carries a gearn meshing with the gear a on the short shaft a, which is provided with a bevel-gear 71 that meshes with a bevel-gear n on the shaft C to which said sprocket-wheel C is secured.

Motion may be communicated to the supplemental carrier-chain C by any suitable means or mechanism, but preferably, as illustrated in the drawings, by providing the shaft it with a sprocket-wheel 02 which communicates motion by a chain 01 to a sprocketwheel 11 on a shaft n, to which the drivingpulley O of the supplemental carrier 0 is secured.

Motion may be communicated to the shaft f, which actuates the shaker F, by any suitable means, but preferably, as illustrated in the drawings, by providing the shaft n with a sprocket-wheel n, by which motion is communicated through a chain it to a sprocketwheel n on a clutch-sleeve f loose on the shaft f, said clutch-sleeve being engaged by an opposing clutch-sleeve f which rotates with the shaft f, so that when the operator by means of the clutch-rod f pulls the clutchsleeve f into engagement with the clutch.- sleeve f the shaft f will be rotated. It should here be observed that the pulley or wheel 0 of the supplemental carrier-chain O, which is on this shaft f, is a loose or idle pulley on the shaft, so that the carrier-chain O can receive no motion from the shaft f, but only from its driving-shaft n as before explained. The other shaker-operating shaft f is actuated from its companion shaft f by means of a chain f engaging sprocket-wheels f f on said shafts f f.

Motion may be communicated to the sewing device or mechanism or to the upright shaft K thereof by any suitable means, but preferably, as illustrated in the drawings, by a bevel-gear K on said shaft K which meshes with a bevel-gear P on a clutch-sleeve P which is thrown into gear with the drivingshaft N by a sliding clutch P said sliding clutch P being automatically operated by a sliding arm 2), projecting into the track B in the path of the bag-holder D, and which sliding harp is provided with an arm 1), that e11- gages the sliding clutch P which thus throws it into engagement with the clutch-sleeve P A spring 19 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-operatin g arm 1).

The operation is as follows: At the station- X, where the conveyer-chain O 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 B to the point where its hook (Z will engage the conveyer-chain. The conveyer-chain then carries the holder along the endless track B to the point where the conveyer-chain G is deflected away from the track B, at which point the conveyerchain 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 IIO shaker out of gear and with his hand liftsthe pivoted hook d on the holder D into engagement with the supplemental carrier-chain O, 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 (1 being automatically disengaged from the supplemental carrierchain 0 at the point where said carrier-chain turns upward or around its pulley or sprocketdle or lever G 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 holder D is now again brought into engagement with the endless conveyer O, a d is by it conveyed past the sewing device K, the operatin g-clutch of which is thrown i to gear by the engagement of the holder with the projecting arm 1:), which operates the clutch; and as the holder passes the thread cutting and holding device L L the thread is automatically severed and its free end ra d and held. As the holder passes along the endless track the arms d and d engage th cams or projections b b on the bridges B B and thus automatically release the clampingjaws d 01 thus permitting the bag to drop out of the holder down upon the discharger M; and at the same time. the springs d on the holder throw the holder open, as it has now reached the point where the guide-fiange h 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 d d are automatically thrown open by passing under the bridges B B they are locked or held in thisopen po sition by the latches or pawls 01 (Z until these latches or pawls are again released by the operator when he puts another bag into the holder. The conveyer O carries the holder back to the station where the bags are inserted, when the operation is repeated sue-- cessively with each and all of the holders of the series. WVhen the holder D is closed by the slide G,

, the short bars 61 are brought into line with the long bars CF, and this act of closing the holder thus throws the hook 01 on the front short bar 61 adjacent to the conveyer-chain 0, into engagement with the conveyer-chain, so that the moment the holder is closed by the slide G it will be caught by. the chain 0 and carried forward along the track B past The holder'closin g slide G holds the holder closed by reason of the spring pawl or hook g until the holder is advanced by the conveyer G into the contracted part of the track B, where the flanges Z; 1) converge to the width of the holder when it is closed, so that said flanges of the track will then keep the holder closed.
