l v `pplieatieu filed August 29,1895. Serial No. 560,831. (No modeLl Tou/ZZ when@ it 71mg/.calmer/1.:- ,Be 1t known that l, YALTER SCOTT, a citiyzen of the United States, and a resident of 'Plainield,V in the county of Union and State of'New ersey,A have invented certain new land useful improvements in Folding Meeh- .anismpf which the following is a speciication.

VThis invention relates to mechanism' for folding sheets, and has reference to such'a construction of the same that cuts or sheets @delivered thereto may be folded without beingcollected, or byla simple adjustment of "the mechanism may be collected and folded. Lit is immaterial whence or how the sheets are supplied to, the folding mechanism.

The invention includes a carrier provided 'with a number of spaces through which foldingbla-des may be protruded, folding-blades differing in number from said spaces, said blades and carrier having different times of eifevolution, so a blade passes the place where thefold is given witheach space, th ns allow ing of folding the-sheets or cuts without any collecting. lf one or more of the blades be rendered inoperative, collecting of sheets take: place`, followed by folding- The invention also includes a rotating carrier-cylinder combined with a folding-blade (or blades) havin g an' axis of revolution eccentric 'to the axis of the cylinder. The times of revolution may be asin the first case men- .The invention also includes other features,

as willbe hereinafter more fully pointed out.

The particular embodiment of the invention shown in the accompanying drawings and hereinafter described includes a carrying -or collecting cylinder Iprovided with three spa-ces through which folding-blades may be protruded and two folding-blades revolving in times different from the times of rotation of the cylinder and having at least two motions, onc of revolutionand the other of rotation. Preferably the motion of revolution of .theblades is about an*l axis eccentric to that of the said cylinder, asthis avoids any in-andled/ting of two non-successive cuts orsheets out or radial motion of the blades in addition tothe two motions ab'ovenamed. make three revolutions about their axis eccentric to that of the'cylinder to two revolu' tions of the cylinder,th us allowing of. the colv being. omitted. .carrier and folding devices or mechanism,

The blades before folding,- one blade being inoperative, or the folding of the cuts orsheets separately, both blades being in operation. This construction permits of collecting but two cuts before thefolding. if a mechanism capaci= tated to collect three or more cuts or none be desired, the rule is to have a carrier provided with a number of spaces through which folding-blades may be protruded greater vby one.

and a numberof blades equal .to the number of cuts'to' be collected. The revolutions of the cylinder and the blades are to each other as the number of blades is to the number of saidspaces. l

Fig. 7 is a diagram showing what cuts from a web are collected in the case of the collecting of two cuts to form one product.

The invention is shown two rotary web-perfecting printing-presses U'and L, Aof usual or suitable construction, and au longitudinal folder F, to which the webs w w' are led around rollers -r and turn ers in a well-known manner. From the rollers. e f of the fold erF the webs pass between the cutting-cylinders m 01, Where they Iare severed into cuts or sheets. .l From this point the-.cuts pass to Athe mechanism embodying the present invention. y

Aj rotatable v carrier-cylinderl C, formed of Figs. 8 to 17, both inclusive, are diagrams in connection with IDO i makesone (l) turn to two-thirds of a turn fof cylinder C, andtha't the cams 1-5 16 are' ends 2 Il, Figs. Sand 4, hoops 4, and. longitu- The spaces a b o betweenthe ties 5 permit of the protrusion of' suitable folding-blades. This cylinder is to be provided with suitable sheet-retainers, as pins or grippers, the latter being shown at 7 as c'o'- acting with the ties 5to hold` the leading or front edges of the cut-s.

The lcylinder C is 'driven by means ofthe toothed gears 8 on or forming the ends 2 3, the gears d'9? on the shaft 10,' which is journaled in the framework A, the gear 1l on a similarly-journaled shaft 12, and the gear 13 on the side shaft 14". 'The'grippers 7 a'rej opened at the proper times by suitable means, as the movable cams 15 16, which are pivoted to the framework, las atv17 18. 'These cams- 15 1G are suitably operated from a convenient lpart ofthe machinery, as by the rods 19 20,

straps 21 2i?, and eccentrics 23 24 on shaft 12. The gears 9n 11 are in the proportion of on-e to two, and gears 9 S are in the proportion of one to three, whence it follows vthat shaft l2 t each alternately'in and out of the positions in Whichthey open the grippers 7. This' is their operation when sheets are collected on cylinder C, `it being understood that any'set of grippers aft-er'bcing opened to take a first sheet by the cam is not opened by cam 16 until suchset passes that earn the second time.' For this reason the eccentrics 2324 are placed at opposite sides of shaft 12. A

The sheets are guided 'to the. grippers by cylinder C, by the guides or bars 27,'and thetapes 2S, running'on rollers or pulleys 99', and foldingrollei- There is a second folding-roller 3l for coaction with roller 80.

The sheets folded by the blades .a and the'- rollers 30 v31 are conveyed away by the sets of tapes 2S 32 (the former set running on rollers or pulleys Zland` roller SOand the latter set running on rollers or pulleys 33 and roller. 1 31) and the guide ba'rsor fingers 41 tothe re'v ceiver R. As this particular receiver forms the subject-matter of claims in a pending application tiled October '23, 1,893', SerialI No. 488,896, it need notbe here described,since any suitable receiver may be substituted for it without departing from the present invention.
