WALTER SCOTT, OF PLAINFIELD, NEW JERSEY.

SPECIFICATION forming part of Letters Patent No. 793,611, dated June 27, 1905.

Original application filed October 22,1900, Serial No- 33,818. Divided and this application filed March 26, 1901. Serial No. 52,877.

To all 1071 0171, it may concern;

Be it known that I, WALTER Score a citizen of the United States, and a resident of Plainfield, in the county of Union and State of New Jersey, have invented a certain new and useful Improvement in Delivery Mechanism for Printing-Presses, of which the following is a specification.

. The present application is a division of my prior application for Letters Patent of the United States, filed on the 22d day of October, 1900, and serially numbered 33,818.

The principal object of the present invention is to cut, fold, and deliver printed copies from one or more webs with or without collecting such cuts; and the invention consists of features of construction, arrangements, and combinations of devices hereinafter described, and more particularly pointed out in the claims concluding this specification.

The preferred form of the invention is illustrated in the accompanying drawings, forming part of this specification, in which- Figure 1 is a View from the end of the folding and delivery mechanism, the frame being omitted and some parts being shown in section. Fig. 2 is a view, partly in section, on the vertical plane through the axis of the carrier, the View being from the left in Fig. 1, and certain parts in front of said plane being shown in this figure.

Referring tothe drawings, the reference 1 indicates an internal guide or V shaped former; 2, drawing-rolls at the point of said former; 3, a rotary sheet-carrier below and to one side of the former; 4:, a cutting-cylinder coacting with the carrier 3 to sever sheets from the web or webs folded by the former 1 and rolls 2; 5, folding-rolls between which the cuts are forced from the carrier 3; 6 7, guides for the cuts after they leave the rolls 5; 8, the arms of an S-fly or delivery; and 9, traveling tapes onto which the arms 8 and guide 7 lay the folded products.

References 10 11 12 indicate sheet-receiving surfaces of the carrier 3, each of said surfaces having a cutting-groove 13 therein to coact with the cutting-blade 14 of the cylinder 4. There is a set of impalingpins 15 for each of the surfaces 10 11 12, which pins are or may be of the usual construction and mode of operation. 16 indicates the usual springrods whereby said pins are protruded from the carrier 3. The sets ofpins are just in rear of the grooves 13 and impale the web or webs before the cutters 1 3 14 sever the same. The pins 15 are drawn inwardly of the carrier 3 by means of a fixed cam 17, which coacts with bowls 18, connected, as usual, with the pins as the pins approach the line of tangency between the web or webs coming from rolls 2 and the carrier 3, said cam 17 being so shaped as that the bowls and pins are released by it as or after the points of the pins reach said line of tangency, whereby the pins are thrust through the web or Webs as it or they lie upon the carrier, and do not, as heretofore, project out as they approach said line of tangency and tear elongated holes in the web or webs or sheet. When it is desired to release the sheets, as in folding off between the rolls 5, the pins 15 are drawn inwardly of the cylinder 3 by means of a rocking cam 19, which is fast on a shaft 20, journaled in the framework of the machine. A spring-rod 21 is connected to the shaft in such wise that it tends to draw cam 19 inwardly or toward the axis of the carrier 3. The shaft 20 has an arm 22 thereon, which is provided with a bowl 23, which coacts with a rotatory cam 24:, having an axis of motion eccentric to the carrier 3. The cam 19 is provided with a hole 25, which in the extreme outer position of the cam 19 registers with a hole 26, threaded, if desired, in the fixed framework of the machine. By inserting a suitable pin through the holes 25 26 when they are in line of register with each other the cam 19 may be locked in its outer or pin operating or working position.

Two folding-blades 27 28 are revolubly connected with the revolving frame 29, whose axis of motion coincides with that of the cam 24, which axis therefore is eccentric to the carrier.

30 represents gears fast on the shafts of the blades 27 28, and these gears 30 mesh with gears 31, journaled on the frame 29. The gears 31 mesh with gears 32, each of which may be fixed against motion by putting pins 32 through holes therein and into holes 33 in the frame of the machine or which may be made to revolve with the frame 29 by inserting said pins through holes in these gears and into holes in said frame 29. The shaft 34, to which frame 29 is fast, is driven by a train of gearing 35, while the carrier 3 is driven at a different rate of speed by a train of gearing 36. As. shown in the drawings, the train of gearing 35 causes the frame 29 to make three turns, while the train 36 causes the carrier 3 to make two turns, being in this respect the same substantially as in my Letters Patent of the United States granted December 1, 1896, and numbered 542,280, to which reference is made for a more complete description of the construction and operation of the carrier 3 and its supports.

37 is a set of tapes running on pulleys 38 and coacting with the upper part of the carrier 3 to retain the sheets thereagainst and to feed them along, so that they will register with the downcoming web when the pins 15 are drawn in by the cam 17 above mentioned.

39 indicates the pitch-circles of a gear connecting the carrier 3 with one of the rolls 2 to drive the said rolls, which are geared together.

In the instance illustrated in the drawings power is derived from a shaft 40, which has a gear 11 fast thereon.

42 is an intermediate gear connecting gear 11 with one of the gears of the train 36 on a shaft 43.

The S-fly 8 is driven from the shaft 43 by a train of gears 14, and the tapes 9 may be driven in any suitable manner, as from the shaft 40.

The operation of the above-described folding and cutting apparatus is as follows: In the drawings one of the gears 32 (that at the right in Fig. 2) is shown (in Fig. 1) as pinned to the frame 29 and as unpinned from the main frame of the machine, while the other gear 32 is pinned to the main frame of the machine and is unpinned from the revolving frame 29, and the cam 19 is free to be moved to and fro by the cam 24: and the spring 21. Consequently, as in my Letters Patent aforesaid as fully set forth, the blade 27 is inactive and the blade 28 is operative to fold off sheets between the rolls 5 in substantially the manner set forth in said Patent No. 572,280, and the description thereof need not here be repeated.

Each set of pins 15 is drawn inwardly of the the pins, and the sheets are cut off by the grooves 13 and the blade 14. The blade 28 is shown in its folding-off position in connecblade 28'is about one hundred and eighty degrees away from rolls5 and that blade 28 will overtake surface 11 and fold off the sheets thereon as that surface passes rolls 5. Then surface 12 will receive a sheet, pass rolls 5 while the blade 28 is at the other side of the carrier 3, receive asecond sheet, and its pins 15 will be withdrawn by cam 19 as that surface 12 again passes the rolls 5, at which time the blade 28 will force the sheets on said surface 12 out between the rolls 5. The cam 19 is moved to its non -working position each time the next sheet-receiving surface passes rolls 5 after a folding-0E operation, and so on indefinitely, the pins being withdrawn each time they approach the downcoming web and being protruded to impale the same as described, whereby sheets are collected by twos and are folded ofi from the surfaces 10 11 12 in the order 12 11 10, whereas these surfaces pass the rolls in the order 10 11 12. The folded sheets pass down between the guides 6 7 onto the S-fiies and are thence laid upon tapes 9 in a known manner.

When single cuts orsheets are to be folded off by the apparatus above described, both 9 gears 32 and cam 19 are pinned to the fixed framework, whereupon each blade 27 28 will operate to fold off each time it passes the rolls 5, and each set of pins 15 will be withdrawn by cam 19 each time it passes said cam, so as to release the heads of the sheets as the blades 27 28 fold them off between the rolls 5,whence the copies are delivered as above set forth, the only difference being that each arm of the S-flies this time receives a sheet, whereas when collecting sheets as above described it is only every other one of the arms that receives sheets and drops them onto the tapes 9. It is obvious that more than one Web may be folded by the formerl and drawing-rolls 2 without affecting the operation of the mechanism hereinbefore described.

By preference the carrier3 is made slightly greater in circumference than the lengths of the sheets to be carried on the surfaces thereof, the purpose being to have the sheets pull up taut on the pins 15, so as to prevent their tail ends from being back over the following groove 13 when collecting sheets, for narrow strips would otherwise be cut in many instances from such overlapping tails at the following grooves. The increased length or circumference may be one-sixteenth of an inch, more or less. The paper as it is drawn down from the rolls 2 is slightly stretched by the tension thereon,which stretch is relieved when the sheets are severed from the web or webs, whereupon the tails of the sheets draw away from the grooves 13 when these are farther apart than the circumference of the cylinder 4 or the distance between knives on said cylinder 4, since the pins 15 pierce the paper without tearing the same.

The carrier or collecting-cylinder 3 may have an odd or an even number of sections or sheet receiving surfaces, according to the number of sheets to be collected.

The cutting-blades may be placed upon the carrier 3, and one or more grooves for coaction therewith may be placed upon the cylinder 1. Also the cylinder 4 may collect sheets on one or more sheet-receiving surfaces thereof and then transfer them to carrier 3 to be folded off with sheets collected upon carrier 3, as in Letters Patent of the United States No. 652,817, dated July 3, 1900, or cylinder 1 may collect part of the sheets and fold them off to another delivery, as in a prior construction shown in Letters Patent to Crowell, No. 255,723, dated March 28, 1882. In this Way a great variety of combinations of printed sheets may be folded together. Inasmuch as sheet-retainers and folding-blades on cuttingcyli nders, with mechanism for operating them, have long been known in this art, said modilications may be made by any one skilled in the art.

Having thus fully and clearly described my invention and its mode of operation, what I claim as new, and desire to secure by Letters Patent of the United States, is-

1. The combination with a rotating carrier provided with a plurality of sheet-receiving surfaces, of means for laying sheets of paper upon said surfaces in succession, sets of impaling-pins on said carrier, one set for each surface, and means for drawing in said pins as they approach the line of tangency between said carrier and the paper and for protruding ber and retaining-pins, means for drawing in said pins before they reach the line of tangency between said carrier and the paper and for protruding them to pierce the paper by their endwise movement, a rotating foldingblade mounted on a shaft mounted in the fixed framework and parallel with and eccentric to the axis of the carrier and revolving once for each pack of collected sheets folded off, and two folding-rolls between which said blade passes the sheets, substantially as described.

3. The combination of a cutting and collecting cylinder provided with aplurality of sheetreceiving surfaces, and a set of retaining-pins for each surface said pins having endwise motion only and each surface being slightly longer circumferentially than the length of the sheet laid on said surface with means for drawing in said pins before they reach the line of tangency between said carrier and the paper and for protruding them to pierce the paper by their endwise movement, substantially as described.

Signed at New York city, in the county of New York and State of New York, this 2d day of January, A. D. 1901.
