To all whom it may concern:

7 Be it known that I, HOWARD M. BARBER, a citizen of the United States, and resident -of Stonington, in the county of New London and State of Connecticut, have invented a newand useful Improvement in Sheet Collecting, Associating, and Folding Machines, of which the following is a specification.

The object of this invention is to provide novel means for associating extra sheets fed from different sources of sheet supply, such, for instance, as cover and insert sheets, with a collected group of sheets fed from another source of supply, means preferably being employed for stitching the so associated sheets together for folding the same.

My invention more particularly includes a rotary sheet associating carrier, a rotary sheet collecting carrier arranged totransfer groups of sheets to the associating carrier, and rotary sheet carriers each arranged to transfer a sheet from a source of extra sheet supply to the associating carrier whereby the collected group of sheets and the sheets from the difi'erent sources of sheet supply are combined on the associating carrier.

vA practical embodiment of mya-invention is represented in the accompanyingdrawings, in which Figure 1 represents a detaillongitudinal vertical central section through so much of a sheet collecting, associating and folding machine, as includes my invention,

Fig. 2 represents a similar section taken just inside the near side frame,

Fig. 3 represents a similar section taken just inside the far side frame, and I Fig. 1 is a similar section taken just outside the far side frame, showing the geared connection between the several parts.

1 designates a source of extra sheet-supply, such, for instance, as an insert sheet supply. 2 designates a difierent sourceiof extra sheet supply, such, for instance, as a cover sheet supply. These sources 1 and 2 are herein shown as feed tables, the table 1 being provided with a movable sheet stop 3 and the table 2 with a movablesheet stop 4:.

Rotary cutters 5, 6, mounted on suitable shafts 7, 8, are arranged to cuta single web or a plurality of superimposed webs which pass between the rolls 9, 10, into sheets, which sheets are passed downwardly between the guides 11, 12, to a three way collecting rotary carrier 13, mounted one-shaft 14, which carrier, in-the present instance, is shown as being provided with three sets of grippers 15. Tucking disks. 16, mounted on the shaft 17, serve to insure the engagement of the advance edges of the sheets by the grippers 15. v

The rotary sheet associating carrier 18, mounted on the shaft 19, is herein shown as havlng three sets of grippers 20. rotary sheet transfer carrier 21 mounted ,on the o5 shaft 22 is provided with a; set lofigri ppers 23 arrangedto feed an extrasheet as, for in,- stance, an insert sheet, from 'the source of extra sheet supply v1 to the grippers 20 on the rotary sheet associating carrier 18. A rotary sheet transfer cylinder 24, mounted on the shaft 25, is {provided with a set of grlppers 26 arranged to feed a sheet, such, for instance, as a cover sheet, from the source of extra sheet supply 2 to the grippers 20 on the sheet associating car-rier18. I A stitcher table 27 is arranged to receive the associated sheets, on which table the sheets are stitched transversely of their travel by the coacting parts 28, 29, of two or more stitchers. A movable stop30is located at the outer endof the stitcher-table 27 in position to engage the advance edges of the associated sheets and hold them momenta rily in position for the stitching operation. Coacting rotary carriers 31, 32, mounted on their respective shafts 33, 34,,are',provided, the carrier 31 havinga set of grippers 35 arran edto take the stitched-assoe ciated sheets from the stitcher table 27 and also having a folding blade3 6 arranged to coact with the folding jaws 37 on the-rotary carrier 32 for imparting a transverse fold to the associated sheets along their trans versely stitched line. i Endless carriers 38, 39, serve to carry the associated sheets .onto and off from the stitcher table 27 and endless carriers LO, 41, are arranged to carry the product from the rotary carrier 32 to a-suitable delivery 42, The train of gears, designated by 14 to 7-1 inclusive, is operative to drive the parts at the proper relative speeds. I I i A switch 72 is located at thetentrance end of the stitcher table 27, which-switch TSQPfi erated from a cam 73 on the shaft 33 of the rotary carrier 31 through the connection 74:

A fixedcam 75 opens the grippers :15 successively at their sheet; receiving point. Movable cams =7 6, -7 7, open the grippers '20 and 15, every two-thirds of a revolution of the rotary carriers 18 and 13 to transfer a group of sheets from the carrier 13 to the carrier 18. These movable cams 76, 77, are operated from the rotary cam 78, on the shaft 79, through the connection 80. A movable cam 81 operated from the rotary cam 82 on the shaft 22 through the connection 83, is arranged to open alternate grippers 20 on the associating carrier 18 to receive a sheet, as, for instance, an insert sheet, fed from the source of extra sheet supply 1 by the rotary carrier 21.

A movable cam 84 operated from the rotary cam 85 on the shaft 25 through the connection 86 is arranged to open alternate grippers 20 to receive an extra sheet, as, for instance, a cover sheet fed from the source 2 of extra sheet supply, by the rotary carrier 24.

A fixed cam 87 is arranged in position to open the grippers 23 to transfer the extra sheet therefrom to alternate grippers 20 on the associating carrier 18 every vrevolution of the carrier 21. A fixed cam 88 is arranged in position to open the grippers 26 to transfer a sheet to alternate grippers 20 on the associating carrier 18 every revolution of the rotary carrier 24.

A movable cam 89 operated by the rotary cam 90 on the shaft 22 through the connection 91, is arranged to open alternate grippers 20 on the associating carrier 18 to re lease the associate group of sheets and extra sheets from the difierent sources of supply to permit the so associated sheets to be fed onto the stitcher table 27.

The grippers 23 are tumbler operated for taking the sheets from the source of sheet supply 1, the tumbler 92 being controlled by the pins 93, 94. The grippers 26 are also tumbler operated to take the sheets from the different source of sheet supply 2, their tumbler 95 being controlledby the pins 96, 97.

The movable sheet stop 3 is controlled by the cam 98'Wl110l1 is arranged to engage the stop roller 99.

The movable sheet stop 4 is controlled by the cam 100 which is arranged to engage'the sheet stop roller 101.

The sheet stop 30 is controlled by the cam 102 which is arranged to engagethe sheet stop roller 103.

The set of grippers 35 on the rotary car-' rier 31 is tumbler operated to take the sheets from the stitcher table 27, the tumbler 104 being controlled by pins 105, 106.

v The coacting folding mechanism on the rotary carriers 31, 32, is of the well known floating blade and jaw type, the operation of the blade 36 being controlled by the cam 107 and the operation of the jaws 37 being controlled by the cams 108, 109, 110.

-A fixed cam 111 is arranged to open the t5 grippers-35 at the time of folding.

Positively driven rollers 112, 113, bear against the surface of the rotary carrier 18 and positively driven rollers 114, 115, bear against the surfaces of the rotary carriers 21, 24, for holding the sheets in register on their respective surfaces when their grippers are opened.

In operation the rolls 9, 10, are arranged to feed one or more Webs to the rotary cutters, 5, 6, the collected sheets are severed from the web or webs, and fed through the guides 11, 12, to the collecting carrier 13. The carrier is herein shown as being an ranged to collect two sheets or groups of superimposed sheets and transfer the same to the associating carrier 18 on top of an extra sheet, as, for instance, an insert sheet fed from the source of sheet supply 1 to the associating carrier 18 by the rotary carrier 21.

The rotary carrier 24 is arranged to transfer a sheet, as, for instance, a cover sheet, from the source of extra sheet supply 2 to the associating carrier 18 on top of the group of sheets. The so associated sheets are then fed onto the stitcher table 27 the switch 7 2 being depressed to insure the passage of the so associated sheets onto the table. These associated sheets are fed against the stop 30 and While held momen- 9 tarily thereby, the sheets are stitched transversely of their travel. The sheets are then released by the stop 30 and their advance edges are taken by the grippers 35 of the rotary carrier 31. The sheets are then folded off transversely of their travel along their stitched line onto the rotary carrier 32 and from thence they are fed by endless carriers 40, 4-1, to the delivery 4-2, 43.

From the above description it will be seen that the sheets from the different sources of extra sheet supply are fed'to the same side of the associating carrier at dilferent points thereon and that the group of sheets 5 are fed to the associating carrier at still another point, the associating carrier'being arranged to first take an extra sheet as, for instance, an insert sheet, then take a group of sheets on top of the insert sheet, and finally take another extra sheet, as, for instance, a cover sheet, on top of the groupof sheets and feed the same to the stitcher table. This makes a very simple and efiee tive arrangement.

It is obvious that the rotary carrier 13 can collect a group of single sheets or a group of superimposed sheets and it is also obvious that the extra carriers 21 and 24 may feed one or more sheets from their respective sources of extra sheet supply, Without departing from the spirit and scope of my invention.

It is evident that changes may be resorted to in the form, construction and arrangement of the several parts without departing 13c from the spirit and scope of my invention; hence I do not WlSh to limit myself strictly to the structure herein shown and described,

to the associating carrier, and means for stitching and folding the so associated sheets together and delivering the same.
