1 To all whom it may concern.-

Be it known that 1, WILLIAM SPALCK- HAVER, a citizen of the United States, resid- Lngat New York, county of Kin s, and State of ew York, have invented certain new and useful Im rovements in FoldingMachines,

' fully descrlbed and represented in the following specification and the accompanying ments in folding-machines.

, folding printed sheets, such as awmgs, forming apart of the "This invention relates to same. certam 1n1pr0veparticularly in newspapers, it

In folding sheets, and more is 'customar y after the sheet has been folded 'Which fold is on a line at to page size to give it a single fold at right angles to the columns of the page, this fold .b emg known as the carrier-fold. Most newspapers are delivered folded in this man In some instances the paper is given what is sometimes termed a mailing-fold, right angles to the these papers being mg-wrap- In some instances still another fold is given the aper, this fold being arallel to the last f0 d and central of the f0 ded sheet, this fold bringing the paper down to the roper size for the wrapper which is placed t iereon, so that it is not necessary to fold during the Wrapping preceding or carrier fold,

operation.

. the folded publication make a Certain publications the pages of which are considerably smaller than the ordinary newspaper-page are prepared for delivery by giving them a fold transverse to the page and then a second fold parallel thereto. T his method of folding has the advantage that displays the entire page head or name of the publication. This method of folding cannot, however, be adopted in newspapers for the reason that two folds such as have been. described would ackage too large to be easily handled, and if the paper be given still another arallel fold the package would be clums or mailing purposes' It is the object of this invention to produce a folding-machine which shall reduce a sheet, newspaper, or similar publication to a convenient size for mailing or the pocket, the folds being reduced in such a manner as to make it possible to display the head of the page which ma contain the title of the pubicatlon. V

The invention. extends to certain details of construction, as will hereinafter appear.

With these and other ob ects not specific- "ally referred to in view the invention consists in certain constructions and in certain parts, improvements, and combinations, as

will be hereinafter fully described and then specifically pointed out.

In the drawing the figure represents in diagrammatic side elevation a. folding nachine embodying the invention.

In the machine illustrated in the drawing, which machine is particularly adapted for folding newspapers, devices are, employed for giving the sheet what may be termed a central-page fold. When a machine embodying the invention contains mechanism for giving this central-page fold, it may be of any suitable or desired character. in the particular construction illustrated there is provided a pair of cylinders i 2, the cylinder 1 being a cuttingwylindcr of ordinary construction and the cylinder 2 being a foldingcylinder, such as is commonly used in connection therewith, this cylinder being provided with rotating blades 3 4. These rotat ing blades cooperate with a pair of rolls 5, the constructlon and operation of devices of this character being well understoo When devices such as have been described are employed in the machine, the sheet after being folded is forwarded to other folding de-' vices by which it is given two parallel folds, the first of which is at unequal distances from the front and rear edges of the sheet, the sheet, if it be a folded sheet, being forwarded in a path at right angles to itsfolded edge.

The folding devices by. which the folds just referred to are effected may be of any desired character. In the articular construction shown two pairs of re is are employed, the rolls of one pair being marked 6 and the rolls of the other pair being marked 7. Cooperating ed on a shaft 9. This shaft is mounted in bearings carried on projections 10 from a cross-bar 11, this bar rotating 011 journals 12. The bar is rotated by a gear 13 in mesh with a gear 14, which forms part of a train from the main driving-shaft of the machine, the speed of rotation bein such that the blade meets anc folds each sheet as it is advanced by the sheet-forwarding mechanism, to be with these rolls is a blade 8, which is mountit is drawn by the folding operation.

hereinafter described. The blade not only rotates about the axis of the bar 11, but also has a rotating movementabout its own center, this being produced by a gear .15 travcling on a stationary internal gear, (indicated at 16.) These gears 16 are so related to ach other that the blade is in tucking position with respect to the rolls 6 7 as it passes them in its rotation around the axis of the bar 11. This general type offolding mechanism is well known in the art, and any other suitable form of, mechanism maybe substituted t herefor.

The sheets after having the rolls 5 are directed by a switch 17 into a tape-pathway consisting of upper and lower tapes 18 19. The tapes l.) pass over rolls 20, 2 l, and 22 to the right-hand one of the rolls 6. From this roll they pass. down between the rolls (3, un der the left-hand roll 6, and then over rolls 23, 24, and 25. From the roll they pass between the rolls 7 and around the left-hand one of the rolls 7. After leaving the rolls? they pass over aseries ol' guidewolls 26'to a roll 27, which is located adjacent to another folding mechanism, which will be hereinafter described. From this roll 27 they pass under a roll 28 to and. around a roll. 29, located on the other side of-the folding mechanism referred to and then back to guideaolls 30 and 31. The tapes 18 run around a roll 32, which in the partieulai' machine illustrated is shown as located between the rolls .20 and 2] and is positioned so as to give the tapes :1 ppm bend between these rolls. From the roll, 32 these. tapes pass over the rolls 2! and 12 before referred to and to and around a guide-roll 33, which located to the left of the lOftll{i-l'l(l roll 6.

and 25 referred to. After leaving. the roll 25 these tapes pass over a roll ttt, l()('lll(.(l to the right of the right-hand roll '7. From this roll 34 they pass around the right-hand roll 7 and between these rolls. From these rolls they run through the group of rolls as referred to and-around the rolls 27 and 23. From the roll 28 they return around rolls 35, 36, and 37. After leaving the rolls the sheet is directed by the switch 17 and an upper guide 38 into the pathway formed byt he tapes before described and is carried along until it meets and is folded by the blade R and the cooperating rolls 6. The front :'.i(l of the sheet is freed from the grip of the tapes as it passes over the right-hand roll, the loop ormed by the run of the tap b in around the roll 33 forming a pocket into which the lead- I I i l 111g end of the sheet can run and out of which This blade 8 and the speed oi the tapes are so timed that the blade. as has been before indicated, gives the sheet a fold which is at onequal distances from its front and rear ed ges.

hrorn this roll 32% these T taies run betweenthe rolls (3, around the loft-hand roll, and then over the guides 2.3.24,

In the best constructions this fold will be at a 1 l distance from the front edge of the sheet equal to one-third of its-length.

.While the tape pathway might be desheet to the blade, in the construction shown folding position. After the'sheet h'asbeen tucked by the blade between the rolls 6 and the fold formed it is forwarded by the tapes around under the roll 7, the leading end of the sheet, as before, running into a pocket formed by the run of the tapes 18 around the troll 34. A stop, as 40, may, if desired, bev

madein such a way that the sheet, referrin to its length as'it enters the tapes, is reduce to m1e-third of its length by folds which are equal in. size. In many cases it will be desirable to give the sheet an additional fold, which reduces its width. In the best constructions this fold will be made centrally of I the width of the sheet, and it may be given the sheet by mechanisnrof any desired char- 1 actor. in the construction shown the sheet 1 is rarried by the run of the tapes heretofore described between guides 41 and 42, these guides underlying a. folding-blade 43, harm an upward extension 44, pivoted to a the blade receives a parallel motion. This is a usual construction of folding-blade and may be operated in any desired nr-n'ner. This folding-blame tucks the sheet between rolls 47, which in turn deliver it to a lotating flydeliver 48, also of usual type. This fly-delivery deposits the folded papers on a traveling belt, one of the so porting-rolls of which is indicated at 49. T ns rotating fly and the rolls 47 and 49 are driven in the usual inanuer by gearing, which is illustrated in the drawings, but which it is not necessary to i describe.

In addition to the deliverybefore described it may be desired to deliver the pa ers directly from. the rtills 5 without furt ier fold 1 than it receives front these rolls. When this is desired, the machine maybe provided with i a rotating fly-delivery 50, and the guide 17, i before referred to, will be formed as a switch, which may be thrown in so as to close the iathwav between this guide and the guide 38. W hen this is to be done, the papers will be de pended on entirelyjho properly present the these folds in the best constructions being.

rock-aria -15, a link 46 being provided so that' a stop, as 39, is employed, against which the' leading end of the sheet abuts as it comes into oemploy'ed to stop the sheet in'the proper polivered directly from the rolls 5 into the rotating :tly delivery andwill be deposited by it on traveling tapes 51. This fly-delivery 50 will be driven by gearin (generally indicated in the drawings,) W iich it is unnecessary to describe.

Changes and variations may be made in the construction by which this invention is carried into effect. The invention is not, therefore, to be limited to the specific details of construction hereinbefore described.
