Application filed December 29. 1914-. Serial No. 879,513.
To alt whom it may concern Be it known that I, HARRY M. i os'rsn, citizen of the Fnited States. resident of Minneapolis, county of Hennepin, State of Minnesota, have invented certain new and useful Improvements in Sack Cutting, Folding, and Sewing Machines, of which the following is a specification.
The object of my invention is to provide 'a machine in which the blank for a fabric sack, such as used for flour or other cereals, can be cut, folded and sewed on one end and one side in a continuous operation as the blank passes through the machine.
A further object is to provide a. machine of simple, economical construction and one in which the described operations can be ellectcd by means of comparatively few parts.
Other objects of the invention will appear from the following detailed description.
The invention consists generally invarious constructions and combinations, all hereinafter described and particularly pointed out in the claims.
In the accompanying drawings forming part of this SPQClfiCtllZlOH, Figure 1 is a side elevation of a machine embodying my invention, Fig. 2 is a longitudinal vertical sectional view of the same, Fig. 3 is a plan view of the machine, Fig. 4- is an end. elevation, Fig. 5 is a detail view, illustrating the means for delivering and feeding the sack at the end of the machine, Figs. 6 and 7 are detail sectional views, illustrating the o eration of the cutting roll and the means or feeding the blank between the belts preparatory to sewing one end of the sack, Fig. 8 is a do tail view of the device employed for cutting the thread between adjoining sections, Fig. 9 is a sectional view on the line w-m of Fig. 8, Fig. 10 is a sectional view on the line ;I -g of Fig. 8, Fig. 11 is a detail view of the. ratchet mechanism for operating the intermittently moving reel, Fig. 12 is a detail elevation of a portion of one side of the machine, showing the driving means for the feed rolls. 7
In the drawing, 2 represents toe ame o the machine. 3 is a shaft, hori ontally mounted therein and preferably lengthwise of the machine and having a pulley 4 for a belt connection with some suitable source of power.
5 is a horizontal shaft, mounted transversely of the machine and driven from the shaft 3 by a suitable worm gearing 6. A
beveled gear 7 is mounted on the shaft 5 on the opposite side of the machine and is geared to an upright shaft 8 which, in turn, is geared at 5) to a horizontal shat'tltl that is mounted in the upper portion of the machine frame. A feed roller 11 is mounted on the shaft 10 in frictionaliengagementwith a similar roller 12 that is spring pressed toward the roller ll in the usual way and the shaft 10 has a driving connection through a belt 13 and a sprocket wheel 13' with a feed roller 14 beneath which is a siu'iilar. roller 15. This sprocket wheel 13 is driven through a suitable gearing from the shaft it A bolt of cloth 16 is supported in suitable brackets 17 and the free end of the cloth is fed between the rollers 14 and 15 and is allowed to drop and lie loosely upon a. plate or table 18. From this table the cloth passes over the feed roller 11 and down between it and the roller 12, as indicated in Fig. 2. 4 i
A gear 19 is mounted on the shaft 10 and meshes with a gear 20 on a transverse shaft 21. A mutilated gear 22 is mounted on the shaft 21 in position to engage the teeth of a pinion 23 on the shaft of a. cutting roll 24 that is provided with a cutting edge 25 extending spirally on the roll and cotiperating with a stationary blade 26 to sever the cloth as it passes between them. 'Evidently the cutting roll is operated at predetermined intervals, governed by the position of the teeth on the gear 22. Normally this roll is held out of its cutting position by'means of v a notched cam 27 that is engaged by one arm 28 of a bell crank that is pivoted at 29 and has its second arm 30 in position to be engaged. and tripped by the pin 3t on the gear 22. Normally the arm 28 will engage the shoulder of the recess of the cam 27 to hold the cutting roll in the position indicated in Fig. 1, a spring 32 being provided for yieldingly supporting the arm 28 in engagement with the cam. Just before the teeth of the gear 22 come into mesh with the teeth of the pinion 23 the pin 31will engage the arm 30 and trip the bell crank, releasing the roll and allowing the gear 22 to operate it and cut the sack blank. During the time that the next blank is being fed forward, the cutting roll will remain inoperative to again be released and perform the cutting operation when the teeth of the gears 22 can come into engagement with the pinion 23. The period of operation of this cutting roll governs, of course, the width of the blank and the sack. A cam 33 is mounted on the shaft ,5 in position to engage an arm 34 mounted on a rock shaft which is journ aled in trans verse hearings in the machine frame and is provided with upwardly extending arms 36 having forked uppe en'ds which straddle screws 37 adjustahly mounted in the rear edge of a pusher bar 38'whichiis arranged transversely of the machine and 'slidable on rods 39 supported on each side of the machine frame. The screws 37 have stops 40 and 41 upon opposite sides of the forked ends of the arms 36 so'that when'the said arms are rocked, the screws will be reciprocated to operate the pusher-bar. The forward edge of the bar is preferably tapered, as indicated at 42, and is on a level substantially with the space between the rows of he feed belts 43 and 14, so that when the sack blank drops down in its vertical position in front of the feed belts, the movement of the pusher bar will press a fold of the blank in between the feed belts and at this time the cutter roll will sever the blank and allow it to be drawn in between the belts to complete the folding operation and where it will be engaged by the sewing machine. The feed belts operate horizontally, one above another, and a plurality of fingers 45 are mounted between the belts over which the bagblank is fed. These feed belts are operated in any suitable manner, preferably by means of a worm gearing 46 driven through a belt 47 from the drive shaft 3. sewing machine 48 is mounted on one side of the machine frame and operated through a belt 49 from the shaft 3 and stitches across one end of the folded blank,
as shown plainly in Fig. 3, to form the bottom of. the sack. A shaft 50 is geared at 51 to the shaft 5 and extends horizontally of the machine and is geared at 52 to a shaft 45 53 which'extends diagonally across the machine and is geared at 54 to a shaft 55 on which a thread cutting knife 56 is loosely mounted and is provided with oppositely arran ed cuttingblades 57 for severing the thread between the sacks. A spring 58. is coiled on the shaft 55 and has a bearing at one end on a pin 59 that is mounted in the knife disk. An eccentric 60 is secured on the shaft 55- and a disk 61 is engaged by 6; said eccentric as said shaft revolves and.
-;raised thereby sufliciently to disengage? a flag 62-on said from a stop .63on the box of the shaft 55.; gThe knife disk is pro yided witha pin 64 which normally engages "the disk 61 and is held thereby against preinature movement. 'V\The n,-,however, the disk 61 is raised and-disengaged from the ;-stop 63, the pressure-.ofithe spring will re- "valve the d'sk 61 and the knife a half revollhition, or ntil the lug 62-strikes the stop 'volves, movement will I connection through a belt 95 with (33 on the underside of the shaft bearing,
whereupon the movement of the parts will be arrested. 'Durin this half revolution of the knife, one of the blades 57 will sweep past the stationary cutter 65 and sever the thread between the adjoining sacks.
By means of the above described mechanism the sack blank is cut from the bolt of; cloth, folded once lengthwise and sewed across one end to close that end and form 5 the bottom of the sack. I will now proceed to describe the mechanism for reversing the position of the sack to increase the capacity of the machine and sewing the longitudinal edge of the sack to complete it.
66 is a cam, mounted on the shaft 50 an 67 is a pliinger having an anti-friction bearing on the periphery of said 'cam and slidable in a uide on the machine frame and having a lin connection 68 with an arm 69 3 5 on a shaft 70. The shaft 70 has a gear 71 thereon meshing with a pinion 72 carried by a head 73 in which a plurality of reel arms 74 are mounted and adapted to pass between the fingers 45 and pick up the sack 90 blank therefrom, accidental displacement of the blank being prevented by means of suitable brads or points 75 on the 'reel arms and the fingers 45. Intermittent movement is imparted to this reel by means of a ratchet 95 mechanism 76 of ordinary construction, premature movement of the ratchet being prevented by adog 77 connected by a link 78 with a lever 79 that is tripped by means of a lug 80 on the cam 66. As this cam rebe transmitted through the ratchet mechanism to re volve the reel and gather up the sack blanks.
At the end of the machine frame a right angled extension 81' is provided. A feed table 82 is mounted to slide transversely of the main frame of the machine upon cross rods 83 and lengthwise of the extension 81., a spring 84 being mounted on one of said cross rods for the purpose of holding the feed table in its retracted position. Said table preferably consists of a. series of parallel rods and a. plate 85 at its forward edge provided with fingers 86 which are adapted to enter annular grooves 57 formed in a lower feed roll 88. The upper roll 89 has feed belts 90 cooperating with those of the lower roll to receivethe partially sewed" bag from the feed table and advance it over the plates 91, which have fingers 92 pro} jecting into the annular grooves in the lower feed roll. The plates 91 project beyond the discharge end of the feed belts to deliver the completed sack out of the machine. A};
shaft 93 is mounted in the extension 81 of the frame and is driven through a belt 94 from the driving shaft 3 andhas a a worm gearing 96 through which the feed rolls 88 and 89 and the belts 90 are operated. The
shat; so has a ram 5)? thereon for operating: the lever 98 which has a pin and fork eon neetion at 99 with the frame of the feed table 82, as shown in Fig. l. and at a pre determined point in the operation of the machine this lever 92 will he rorked to mov the feed tahle toward the feed hells lit) and deliver the partiall; sewed sacl; thereto.
