Specification of Letters Patent. I

Patented Sept. 11, 191?.

Application filed November 2, 1915; Serial No. 59,296.

To all whom it may concern:

Erie, in the county of Erie and State of Pennsylvania, have invented new and useful Improvements in Folding-Machines, of

which the following is a specification.

This invention relates to folding machines and consists in certain improvements in the construction thereof as will be hereinafter fully described and pointed out in the claims.

One object of the invention is to provide a machine which will fold in proper relation double sheets which have been printed on one form. Other uses of the invention may be had and other objects of the invention will appear from the specification and 1 claims.

' The invention is illustrated in the accom- Fig. 5 one part of the slitted sheet after the first fold.

Figs. 6, 7 and 8 the same parts of the sheet 1 carried through successive folds.

Figs.9, 10, 11, 12 and 13 show views similar to Figs. 4, 5, 6, 7 and 8 with relation to the other part of the sheet.

Fig. 14 a plan view in outline of the machine with the slitting devices. t

Fig. 15 a plan view of the reversing rolls and the first folding rolls.

Fig. 16 a view in outline from the left ,of Fig. 15.

Fig. 17 a view in outline from the bottom of Fig. 15. i 1

Fig. 18 a side elevation of the slitting and reversing rolls and adjacent parts enlarged. Fig. 19 a view in outline from the left of Fig. 18.

The sheet is shown in Figs. 1 and 2 and after The reverse side of the sheet has there is an inside part toward one edge and an outside part toward the opposite edge but the entlre material is found on the outside and inside surfaces of each piece A and B. This adds to the rapidity of the printing in that this double form may be used and by running the sheets through twice reversing them the entire form is placed on each part of the sheet. The difficulty with this is that one part of the sheet has outside matter on one surface while the other part ofthe sheethas the outside matter 0n the other surface. Heretofore these parts have been separated in the printing machine and then reversed and each part fed separately to the folding machine. Other methods may have been used in ac complishing the purpose. With my machine this double form sheet is fed to the machine, slitted, and one part reversed relatively to the other so as to bring the inside portion up on both parts over the first fold rolls.

The sheet is slitted on the line 3 as shown in Fig. 3 and the portion A then passes over the firstfold rolls and folded on the line 4 forming the first fold as shown in Fig. 5. It is then folded on 5 forming the second fold as shown in Fig. 6; again folded at 6 forming thethird fold as shown in Fig. 7; and is again folded at 7 a forming the completed book or fourth foldas shown in Fig.

8. The part B is folded in a similar manner on the lines a; 5, 6 and 7 as shown in Figs.

'9 to 13 inclusive. One of these parts, as

stop 8 is carried by an arm 9 on a rock shaft 10. I An arm 11 extends from the rock shaft 10 and is-operated by a rod 12 from any convenient part of the machine and properly timed to deliverthe sheet in the well known manner. The sheet is started by means of the starting rolls 14: and 15. The roll 14: is carried by rock arms 16 mounted on a rock shaft 16 A rook arm 17 extends from the rock shaft 16 and the rod 18 rocks the shaft 16, the rod 18 leading to any suitable cam mechanism (not shown) for this purpose. These are timed so that as the stop is lifted the starting rolls operate and feed the sheet forward.

The slitting roll 19 has a slitting groove 20 in which the disk-shaped knife 21 operates to slit the paper as it runs past the roll. Tapes 22 are carried around the slitting roll andthus hold the paper in contact therewith and in proper relationthereto to be operated upon by the knife. Tapes 22 extend around the roll 23 above the slitting roll, around idlers 24 and 24, the tapes carrying the paper from the slitting roll back under the starting table and over a reversing device. As the parts ofthe paper are earned for ward by the tapes 22 they are separated by a separating blade 25 which extends the full length of the sheet, the-sheet being arrested by a stop 25. This separating blade holds the edges in proper position to be started at the edge by the starting blades hereinafter described and. merges into the guide .by which the sheets are guided between the reversing rolls 28 and 29 hereinafter described;

The reversing device is as follows: The reversing rolls 28 and 29 are arranged immediately under and parallel with the slitted edge of the sheet as it is carried against the stop 25. The blade 25 is carried by a guide 26. The guide 26 is carried by a rod 27 mounted in any convenient manner. The

guide 26 extends between the reversing rolls 28 and 29. Starting blades 30 and 31 are arranged eaehside of the blade 25. They have the upward projections 32 and 33 which are attached to a bar 34.- The bar 34 is carried by the rock arms 35. The rock arms 35 are mounted on therock shaft 36. The rock arm 37 is mountedon the rock shaft 36 and is connected by a link 38 with a rock arm 39.

The rock arm 39 is mounted on a shaft 40.:

A rock arm 41 extends from the shaft 40. A rod 42 extends from the rock arm 41 and has a slotted end 43 which is arranged around a cam shaft 44. A cam roller 45 is arranged on the slotted end 43' and is adapted to drop into a depression46r A spring 42 is mounted on the rod 42 and when the cam roller 45 drops into the cam depression 46 the spring and the weight of the parts through the chain of mechanism depresses the bar 34 thus moving the starting. blades 30 and 31 downwardly bending the edges of the sheets into the bite of the reversing rolls 28 and 29.

The starting rollers 48 and 49 are arranged above the reversing rolls 28 and 29 and are adapted to drop into' contact with the sheets just after the edges are defiected so as to start the sheets past the reversing. rolls. The roll 48 is carriedby the rock arms 50.. The rock arms 50 have the shaft 51. The rock arm 52 extends from the shaft 51 and is connected by a rod 53 with the slotted end 54 arranged on the camshaft 44.- A cam roller 55 is adapted to drop into the cam depression 56. A spring57 is arranged' on the rod 53 and it and the weight of the parts depresses the roll 48 when the roller 55 drops into the cam slot 56. The roller 49 is carried by rock arms 58. The rock arm's'58 are carried by the rock shaft 59. A

rock arm 60 is mounted ontheshaft59 and connected-by a rod- 61 withthe" rock arm 52 so that as the rock arm 52 is rocked to drop the roll-48- it rocks the arm 60 and thus drops the roll 49 into feeding relation.

The sheets are carried over the rolls 28 is carried around the roll 29, the edge being deflected by the guideplate 26and carried onto the tapes 62,.the tapes62 being operated by the roll 63. The sheet as itis carried around the roll 29 is reversed upon it self bringing the inside .1 to the top and the portion A. is thendelivmred over the first fold roll-s64 (see Fig. 15 )-.b-y the tapes 62. From this it is carried in the well-known manner of folding: machines through the rolls 65, 66 and 67.

The part B of the sheet is carried around the roll28 and delivered betweenthe guide plates 68 to the intermediate-rolls 69.- It is deflected as it passes the rolls 69by a deflector 68 carried byone ofthe guide platestapes 72. The sheet; is then folded through the successive roll's 74, and 76. v p 9 With this mechanism, therefore, it will be seen that a single doubleform may be used running the paper twice. and this double sheet is split and one portion reversed; so that both portions: may be properly folded starting with-the fold toward the inside.-

WVhat I claim as new is i H 1 In a paper folding machine,- the combination of a slitting device; reversing means comprising reversing rolls parallelwith the cutting line of the slitting device; conveying mechanism'for carrying" the slittecl sheet from said slittingdevice to the reversing.

rolls; starters carrying. the slitted edges of the sheets into the reversing rolls; a set of' folding. rolls for each part of the slitted sheet and conveying means extending; from the reversing rolls carrying both parts of the sheet to their. respective folding; rolls,
