commodity in position upon the irst disk ject matter of a co-pending application filed i tame 14 which is provided 'with 'a hub 15 and driven by a gear 16 rigidly connected with said hub or formed integral therewith as' portions are found desirable .in operation,

- movement.

the invention is not limited to these specific relations andicomprises` any arrangement for operating the gear 16 with a step by step The gear 17 is operated by a shaft 18 which is driven from any prime mover as the motor indicated conventionally While the particular gearing for driving this shaft 18 from the motor 19 is unimportant and no limitation upon the invention, it is shown inthe drawings as comprising a pinion 20 mounted directly upon the armature shaft 21 and intergeared with a gear 22 carried by a shaft 23. This-shaft 23 is intergeared with the shaft 18 inany v approved manner as by the worm gearing 24 so that, as the motor 19 is operated, the shaft 18 is rotated continuously and through the medium of the mutilated gear 17 oper- I. ates t-he gear 16 intermittently.

t Upon the turn table 14 are mounted a plurality of cups 25 which are -provided with tubular conduits 26 forming'a journal for the free rotation of the cups 25 in the turn table and independent of the rotation of the turn table and communicating with radial tubes 27 which in turn connect with the hub 15. The hub 15 is in communication with a conduit 28vwhich connects with an exhaust mechanism 29 as shown at Figure 1, so that said conduit 28 is under continuous exhaust.

. jThe end ofthe conduit 28 extends upwardly ,action for the purposes into the hub 15 and is cut away as indicated at 3() (see Figure 4) so that three of the tubes 27 are under the action of the exhaust, the fourth being free from such exhaust hereinafter mentioned. I

The cups 25 are provided about or adjacent to their perimeters with a plurality of upstanding penetrating pins 31. As the turn table 14 carrying the plurality of cups .25 is rotated with a step by step movement 1n themanner above described, it brings two of the cups 25 under stripsv 32 of fabric (see Fig. 1) which fabrics are fed from each end by means of points 33 carriedupon sprocket chams 34 which in turn operate over sprockets 35 upon the driven shafts 36 and sprockets 37 u on the idler shafts 38. The s afts 36 are riven by means of anyconvement. gearing indicated conventionally at 39, whchas shown embraces a shaft 40 and 'gears 17, the strips of material 32 are being fed forward a distance to cover the two f cups 25. This feeding mechanism is carried upon a plate 44 which forms a bearing for the shaft 42 and lis held against rotation which extends to and is connected with the upright 13. Above this plate 44 a guide block 46 is located which may be formed integral with the plate 44, as indicated by the section lines at Figure 5, and is held stationary in the same manner by the brace 45, as indicated at Figure 2.l This guide block 46 is provided with bosses 47 registering with openings 48 in the plate 44. The guide block 46 and plate 44 are so arranged that the strip of material 32 passes between the block and plate and over the openings 48 beneath the bosses 47. Mounted to reciprocate in the bosses 47 are cutters 49 proportioned to coact with the margins of the openings 48 to form a shear cut for the fabric 32.

located between the block -46 and the plate '44. Preferably. the cutting edge of thecutters 49 are scolloped as at 50'merely for ,in any approved manner as by the brace 45 Figure 2, the cutters 49 are formed of sheet or similar metal bent to a cylinder with substantially abutting edges as'indicated at 51, permitting Suflicient resiliency of the cutters to at all times properly fit not only the bosses 47 but the cutting opening 48.

These cutters 49 are operated simultaneously by means of a yoke 52,` the ends of which are fulcrumed at 53. The yoke is connected directlyl with the cutters 49. Such connection in-one instance is means of a ring 54 having ears 55 (see Figure 2) pivotedto the cutter 49 at 56. This forms an opening for the introduction of the commodity through the chute 57'which is the connecting element between the weighing machine A and the bagging machine which' forms the subject matter of this application.

with the shaft 18, the cam groove of which preferably by tioned by the assures engages a roller 61 upon the lever 62 connected to the link 63 which in turn connects with the bell crank lever 64 pivoted to the link 59. rl`he groove of the cam is so arranged as vto oscillate the cutters in proper timed relation with the operation of the balance of the mechanism as will be hereinafter more fully described.

'As the turn table 14 rotates, the disks of fabric located thereon will be brought into position to be operated upon by a sewing machine which is indicated conventionally at 65 in Figure 2, vsuch sewing machine per se forming no part of the present invention and any type of machine capable of performing the operation may be employed in ing machine formiment an essential part of the bagging machine but specically unimportant to the present' invention.

ln operation, the strips of fabric material are introduced between the plate 44 and the guide block 46 carried by the teeth 33 of the sprocket chains 34 so that they shall cover' both of the openings 48 in the plate 44. The relation of the gears 16 and 17 is such that conjunction with the bag the gear 17 operates the turn table to bring 25 under the two cutters 49. ln this position both of the cutters descend, operated in thev manner hereinbefore menactuation of the lever 58 to sever two disks from the fabrics 32 and move them downwardly to be impaled upon the penetrating points 31. One of these fabric disks comes directly in contact with the cup 25 and is subjected to the exhaust as mentioned. This serves to hold the fabric in position while the commodity indicated at two of the cups Figure 2 is introduced through the chute 57 Y lycut and pushed and through the cutter 49 upon this disk, the exhaust servingalso to hold the commodity in position owing to the open weave of the fabric which is preferably of a coarse and very open structure. 'llhe cutting of the disk and impaling it upon the enetratin points as indicated at Figure 2, die disks t ere being given the number 32 for identification,

is accomplished simultaneously or approximately instantaneously. rllhe cutters rise and 'the turn table 14 is rotated a fourth of a revolution by the action of the 1 to 4 gearing 17 upon the gear 16 so that the said commodity disk 32 is now brought under`the second cutter and another cup 25 brought under the initial cutter. rlhis action is repeated so far Vas the initial disk is concerned and at the second cutter a second disk is simultaneousdownwardly and likewise impaled upon the points 31, this disk being marked for identification 32" at Figure 2. This cup, the two disks and the contained commodity are still subjected to the action o the exhaust which holds all of the parts properly positioned upon the cup 25 which is Vfirst mentioned cup in f disks on said points,

with the table 14 bringing said position to be acted upon by the sewing machine 65. 'lhe sewing machine engages the extending perimetrical edges of the two disks 32 and 32". forming a stitching thereabout, such stitching being accomplished by the rotation of the cup 25 and the feed of the sewing machine, no other means for rotating said cup being necessary. The sewing machine is preferably of the type which will form a zigzag or binding stitch over the perimetrical edges of said superposed disks, the particular type of sewing machine is not essential to the present invention.

At the next step by step movement of the turn table 14 and its several cups, the bag now sewed and'completed is removed. While some automatic means may be employed for the purpose, none is-here shown and such removal is or may be accomplished manually.

lt will he seen that'at each stop of the turn table 14 a disk is cut, impaled upon the points 31 upon one cup and the commodity introduced upon said disk, while simultaneously a second disk is cut and superposed upon the previously cut disk and contained commodity and at the same time the sewing machine is operating to close the organized units of a complete commodity bag while at the fourth step the completed bag is being removed. At said fourth position, is no longer subjected to the action of the exhaust, so that it may be easily removed, mechanically or manually.
