T 0 all HIIMWI'L it ntmy concern:

Be it known that 1, JOHN F. Anus, a citizen of the United States. residing at Portland, in the county of Multnomah and State of Oregon, have invented new and useful Improvements in Bag-Machines, of which the follon ing is a specification.

My invention relates to a machine for use in making bags, and es ccially bags from cloth, which is supplied in rolls of any desired .quantity, and in uhich machine the cloth is taken from the roll, passed as a continuous strip through a printing-press, by which a desired brand is applied at proper intervals, the strip then being fed automatically and continuously to a suitable cutting device, whereby it is severed into desired len ths, these lengths then folded, and the felt ed lengths finally piled ready 3" or sewing.

The object of the invention is to provide a machine combining bag-printing, cutting, folding, and piling mechanisms, said several mechanisms having coordinated movements, and a wide range of mutual adjustability adapting the machine to the printing, cut ting, folding, and piling of bags of al sizes, having all sizes, shapes, and colors of brands.

The invention consists of the parts and the construction and combination of parts as hereinafter more fully described and claimed. having reference to the accompanying drawings, in which Figure 1 is a side elevation of half of the apparatus, showing cutting, folding, and piling mechanisms. Fig. 2 is a side elevation of the other half of the apparatus, showing printing mechanism and means for feeding the printed strip to the cutter. Figs. 3 and 4 are diagrammatic views corresponding, respectively, to Figs. 1 and 2, showing the fabric in heavy full line, the sprockets in single lines, and the carriers in broken lines. Fig. 5 is a planview of apart of the apparatus, showing the cutter and the presser-roller. Fig. 6 is a side view of same. Fig. 7 is a plan view of a part of the apparatus, showing the folding-blade and guide-bar 31. Fig. 8 is a diagrammatic view showing operation of the folding-blade. Fig. 9 is a perspective view of the piling mechanism.

A represents the roll of stock which is to be printed at regular intervals and cut into suitable lengths, the width of the rolled stock corresponding to the length of the bag to be made.

B is the printing-press taking the stock from roll A, printing it, and passing it on to be taken into and through the cutting and folding machine, the frame of which latter is indicated by the reference-letter (I. For convenience of illustration, the stock in its travel through the press and machine is represented in heavy lines by D.

From roll A, Fig. 4, which is mounted to turn free, the fabric-is carried between the rollers 2, driven in unison with the rest of the machine. Thence it passes between the form or type-cylinder 3 of the press and the impression-eylinder 4, being fed intermittently thereto by means of the feed-rollers 5 6, resting normally on the impressioncylinder. These feed-rollers are operated through the agency of an expansible and adjustable cam 7, Fig. 2, on the shaft of the constantly revolving form cylinder. The cam 7 is composed of a plurality of concen tric sectors, adapted to be opened out or closed up to present a more or less extended surface of contact to the roller 8 on arm 9, by which the periodical raising of the rollers 5 6 is effected. The roller 5 is journaled in the arms 10, keyed to rock-shaft 11, to which the rollenarm 9 is also fastened. Roller 6 is carried by the arms 12, which are pivoted on arms 10, and the two rollers are adjusted by suitable devices, as the set-screws 13, to cause them to bear equally and simultaneously on the impression-cylinder. The roller 6 serves also to strip the cloth from the form, to prevent the cloth following around with the cylinder after making the impression. Thus it is seen that when the cam 7 contacts with the roller on arm 9 the shaft H is rocked to lift both rollers 5 6 from the impressioncylinder. When the cam leaves the roller 8, a spring 14 operates to pull arm 9 back and allow the rollers 5 6 to contact with the impression-cylinder to feed the cloth forward. The period of contact of the rollers 5 6 with the impression-cylinder regulates the amount of feed at each revolution ofthe form-cylinder independent of the contact of the form with the cloth and impression-cylinder, and the amount of feed of cloth depends on the sizeof the bag to be made.

The feed-rollers 5 6 are preferably caused to contact with the impression-cylinder rior to the contactin of the form with the 11 0th, so as to start t e latter in motion and not reduce a smudge as might occur if the feed of the cloth depended on the contact of the form and impression-cylinders alone. The

adjustability of the cam-sectors allows a wide ran e of variation in the time and amount 0 feed to the press. For large bags the sectors would be closed more than for small bags. The two cylinders are driven positively in unison and at the same surface s)eed by reason of the intcrengagement of the gears 16 on the respective cylinders.

18 re )resent the inking-rolls, which are preferably mounted on mljuslable carriages and each adapted to apply a different-colored ink to a different area of the brand.

Leaving the press the printed length of fabric is preferably supported on an inclined plane or table it), which is carried by and ad justablc with the press, as will be more fully explained later. The fabric .asses around a suitable tension device 20, igs. 2-4, and

thence around an adjustable tension-rod 21, whose functions and necessity will be made apparent hereinafter: Thence the cloth asses to the feed-rolls 22 23, by which it is ed intermittently to the knife or cutter 24, Figs. 3 and l, first coming after leaving rolls 22 23 upon the conslantly-runnin tapes 25 and passing beneath the adjustable Presserroller 26, which latter holds the fabric flat, evens out the creases, and keeps the end of the fabric from jum )ing back or buckling when the knife cuts off a section. This roller 26 is important, for the reasons last men.- tioned, and is adjustable in slotted guides 26* to permit it to be moved back and forth. lengthwise of the machine, so that when the cloth is temporarily at rest, being still held by the rollers "22 23, but supported on the constantly-runnin tapes 25, the roller, which also runs constant y by reason of its engagement with the tapes, can be shifted so that it will not rub over the freshly-printed portion of the cloth and possibly blur the brand or smear the fabric.

23, Figs. 2 and 4, is a frame felt-lined on its under side and slidable on a suitable guide 23 and movable lengthwise of and in contact with the upper feed-roll 23. It is for the purpose of wiping off the ink that may possily collect on the roll from the freshly-iniprinted fabric.

Beyond the cutter the severed and printed section d of the strip D is received onto the constantly-running tapes 27 and carried across the transversely-extending bars 28, be tween which the vertically-reciprocating folding-blade 29 crates. The front end of the severed stri dhs caught by a succeeding set of constant y-running tapes 30 and carried against an adjustable guide-bar 3 1 which trues the front ed e of the strip. The guidebar 31 is essentia ,since both carriers 27 30 run constantly, and without the bar the severed section would likely be carried too far or be thrown askew so as not to be folded in the middle. As it is the bar is adjusted back and forth lengthwise of the machine, according to the size of the bag being made, to brin the folding-blade exactly in the middle of the severed section of fabric. By its means I provide a very simple and ellicient device for always getting an exact and uniform fold.

As the severed strip contacts with bar 31 the blade 29 descends and folds the strip lengthwise in the middle, carrying the strip down between the o positely-turning rollers 32, which creaseam deliver the folded strip onto a curved guide 33, and thence onto the endless carrier 34, which latter. advances it betwecnthe two rollers 35, run at accelerated speed. The upper of rolls 35 carries tapes 36, Figs. 9, 3, and 1, which carry the strip-section over a plane surface 37 against an adjustable stop 38 and onto the reciprocating table 39, by which the folded strip, ready for sewing, is piled in the adjustable receiver 40. The tale or sliding frame 39 travels in guides 41 and is moved by a crank-rod 42, connected with the revolving disk 43, operated in unison with the other parts of the machine.

In its forward movement the table 39 is timed to pass underneath the stop-bar 38, between which and the surface 37 is an open space through which the bag drops into the receiver when the support afforded by the table 39 is withdrawn on the backward movement of the latter.

To prevent the crushing or erumpling of the cloth against sto )S 38 by the. backward movement of the table, a strip of metal 45 of suitable width is disposed immediately in front of the stops and sli htly above the plane of movement of the ta do, which serves the purmse of holdin a certain portion of the cloth adjacent to the fold flat against the surface of the table. 7

The receiver 40 is made with respective adjustable end and rear walls 45* 46 to accommodate it to bags and sacks of all sizes. It has a movable slatted bottom or platform 47, which is supported at the ends by the cords, chains, or belts 48, which pass up over the idlers 49 to attach to the periphery of the pulleys or drunis 5O on the transverse shaft 51. The latter is operated by a hand-wheel 52 or equivalent mechanism, and the plat form 47 is held at any suitable elevation by means of the ratchet 53 and the pawl 54, which last is released by the foot-lever 55 and appropriate connections. The platform 47, on which the folded sections are deposited by the table, is suitably guided and steadied in its vertical movements by the underneath rods 56, working in boxes 57 in the floor.

The end walls 45 of the receiver consist of metal plates about six inches wide and carried by and adjustable on the fixed trans- ICC versely-slotted front wall-plate 58, according on upright slats carried by the adjustable frame 59 on the floor. This rear wall may thus be moved back and forth, according to varying bag widths.

The side and ends of the receiver having been adjusted to the length and breadth of a folded bag-blank the platform 47 is raised to within six or eight inches of the table 39. The well or inclosed space thus formed above the platform operates to provide a sort of air cushion for the folded fabric, as the latter drops from the table 39 and occasions a more uniform piling than if the sides of the well or receiver were entirely open. As the receiver is filled, the platform is lowered from tine to time, as desired, by stepping on the lever 55 and releasing the pawl. When the space from the floor to the under edge of the metal plates formin the rear and end walls of the receiver is iii ed, the folded and piled naterial may be removed.

Referrin next to the driving connections, power is (ferived from the main shaft 69, Figs. 4 and 2, operated from any suitable source. A gear on shaft 60 engages another gear on the counter-shaft 61, whence extends a sprocket-chain 62 to a sprocket on shaft 63. From shaft 63 runs a chain 64 to shaft 65 on l the printin -press, whence the form and in.- pression cy inders, inking and feed rolls are operated. Also from shaft 63 extends a c ain 66 to a sprocket 66, geared to one of the rolls 2, which operate the unwinding of the material from roll A. Also from shaft 63 runs a chain 67 to a shaft 68, whence power is transmitted by the respective connections 69 and 70 to run the carriers 25, 27, and 39. The disk 43 is operated by a chain 71 from shaft 68. Also from shaft 63 extends'another chain 72 to operate a shaft 73 and the conveyer 34. The rolls 32 are run from shaft 73 by connections 74 and the rollers 35 and carrier 36 by the connections 75.

Shaft 61 carries a radially-slotted disk 76 and an adjustable cam 77, disposed on a radius approximately at right angles to the slot 78 in the disk. A connecting-rod 79, ad-. justable in slot 78, connects with a sliding carriage 80 on the franie of the cutting and folding machine. The carriage 89 is provided with a rack 81, engaging a pinion 82, loose on the shaft of the feed-roller 22. A ratchet 83 is fast to the shaft of roller 22, and pinion 82 carries an arm having a pawl 84, riding on the ratchet, so that as the carriage 80 moves in one direction or toward the cutter the roller 22 will be turned, and when the carria e is retracted the pawl will ride free overt 1e ratchet and the roller will remain stationary. The amount of rotation of roller 22 will determine the feed to the cutter, and this amount will equal the exact length of fabric to be severed and will be e ual to the feed through the press at each imprinting operation. Variation in the feed to the l knife is effected by shifting the pivot of the connecting-rod 79 in the slot 78 to shorten or lengthen the stroke. Thus it is seen that the adjustirent afforded by the slotted disk 76 and connecting-rod 79 and the adjustment afforded by cam 7 are mutually interdependent.

In order to render effective a fine and-exact adjustment of the feed of the fabric to the cutter relative to the operation of the printing-press, means are provided to limit the rotative movement of the feed-rollers 22 23 beyond that prescribed by the forward movement of the carriage 80, since these rollers have a tendency to continue turning after the power by which they were set in motion has ceased to be applied. To prevent this continued rotation and to bring them to rest immediately and prevent any possible variation in the amount of feed each tune to the cutter, the shaft of roller 22 carries a frictionpulle v 85, Figs. 4 and 2, on which a weight 86 is adapted to rest by gravity, and a brakeshoe 87, iinged at 88,is adapted to be ressed 11 against the under side of the ro ler. This brake is applied the moment the power for accomplishing the rotary movement of the feed-rolls isdiscontinued, through the agency of the ad'ustable cam 77 periodically dc pressing t 0 arm 89, fastened to the rockshaft 90. The latter carries a projection 91, on which the brake-shoe is suitably supported. .This brake mechanism prevents an unequal feeding and assures absolute uniformity in the length of the severed sections of cloth.

The cutting mechanism, which is shown in detail in Figs. 5 and 6, consists of stationary members 24 on the bed-frame and a movable member 24, having a spring-supported pivot at one side of the machine. This pivot comprises a bolt 92, suitably journaled in the frame, and a spring 93 surrounds the bolt and operates always to press that end of the knife in against the stationary cutting member. The opposite end of the blade is movable in a tapered spring-guide 94, which acts in c011- junction with t e spring 95 to press that end of the knife always into close contact with the stationar cutting member. Thus the knife is flexib y supported and guided at each end and operates on the cloth after the fashion of a pair of shears. By mounting the movable blade in this manner the cuttin edges remain sharp for a considerable lengtlg of time.

A spring 96 serves to hold the knife normally open, and its depression at proper intervals is effected by means of the cam 97 on shaft 68 contacting with a roller 98 on the pivoted arm 99, to which is connected the rod 100, the free end of the rod being pivoted to the knife-blade.

The operation of the folder 29 is accomplished by means of a rod or bar 101, fast to and movable with carriage 81) and slidable in The feed of the cloth to the cutter and guides 102. This bar carries a cam 103, folder is intermittent, like that to the press, which on a es a rocker-arm 104 at each revobut is alternative with and at a different rate lution risk 76. Arm 104 is connected of speed than the latter that is, the amount with one end of the folder and is fixed to the of material coming from the ress after each 70 transversely-cxtendingfulcrum-shaft10.5,the imprint will exactly equal the amount opposite end of which is provided with a going to the cutter at each actuation of the similar arm 106, which is connected with the rollers 22 23, yet at the actual time of the forend of the folder on that side of the machine. ward movement of the cloth through the Arocking'of shaft 105 in one direction by the press and to the cutter the rate of speed 75 cam 103 depresses the blade to carry the through the cutting machine is greater than bight of the severed strip in between the through the printing-press, due to the differcreasing-rollurs 3;. The retraction of the ences in the respective feed-o erating means. folder is occasioned by the springs 107. It is obvious, therefore, thati the cloth is fed 1 5 It will be observed that while the feeds to simultaneously into each and not succes- 8o the printing-press and to the cutter are mtermittent the operation of the several endless carriers 25, 27, 30, 34, and 36 is continuous.

The several driving connections are either chains and sprockets or gears in order that every essential part should be positively driven, thereby preventing disarrangement after the machine is once adjusted for a par- 2 5 ticular run of bags.

In operation a roll of cloth A is taken, the width of the cloth being equal to the length of the bag to be made. Cam 7 is adjusted so that its period of non-contact with the roller to on arm 9 will allow the rolls 5 6 to operate just long enough to feed the exact quantity of cloth through the ress as will constitute the width of a severe ba blank before it is folded. The position of tTlB press relative to 5 the cutter 24 is then determined, the press bein mounted on rollers 108 for this urpose and sing movable back and-forth y suitable means, as the screw and hand-wheel 109. The throw of the conn'ectin -rod 79 is then adjusted to render the feed y the rollers 22 23 to the -cutter proportionate to the feed through the printingress, sincethere is seen to be a necessari y-coordinated move-' ment between the printing and the cutting 5 and folding mechanisms.

sively or alternatively therewill be a gain of the feed into the cutting-machine over that by the printing-machine, with the result that the cloth when it is held by the pressure of the printinglate against the impressioncylinder wil e torn y the ull of the feedin -rolls of the cuttingl and fo ldin machine.

he printing mec anism is isposed at some distance from the cutting mechanism and its feed-rollers, and the section of cloth 0 between the press and the feed to the cutter has printed on it at regular intervals various and several impressions of the printing-plate. This separation of the press and the cutting and folding machine is to ermit of the ad- 9 5 justment of one machine reliative to the other that must be made in printing he s of different sizes, since the distance from t e cutting blade to the oint of contact on the cloth of the side of t e printingplate must be definitely fixed in order that the print on the section to be severed be always properly disosed relative to the distance from each edge of the folded section. In other words, the

rint on the cloth must occupy a definite uni- [o5 orm position relative to the cut edge of the cloth. Hence with a continuous strip having successively applied brands the cut must always occur on precisely the same line between any two prmts in order that the sewed r 1 o In many cases where bags are made of a bag-sections should have the prints appear length less than the standard width of the uniform. cloth, the original roll is split in two,leaving For every different size of bag and every the cloth with one selvage edge and one raw different size of brand theposition of the rint 5o edge.

This rod has which space a fold of the fabric is receive its ends adjustable in the vertical guides 110, after each impression. This portion of fabric so that each end may be raised or lowered which is allowed to sag between the table and independently to effect the properangle for the cylinder is exactly the amount that the 60 accomplishing the equalization of thevarying rollers 22 23 will draw forward the next inlen ths of the edges. stant for the cutter.

In Fig. 8 it is noted that each of said arms has an angle-plate 112 pivoted to it at one end, as at 113, each plate having a part extending beneath its arm and resting directly on the blade, which slides up and down in suitable guides on the frame, Fig. 1. A set-screw 115 is threaded in each arm 106 and is adapted to bear on the underneath part of the corre spending plate 112. By turning the screws 115 in one direction or the other the pressure of the two arms on the blade may be regulated so thatthe blade will come down equally and simultaneously on both edges of the cloth and make an even fold. Some adjustment of this sort is essential for best results.
