Application filed August 25, 1926. Serial no. 131,368. r

This invention relates ,to sheet-handling mechanism and a primary object thereof is to provide a mechanism which will form from.

a printed web signatures offolded sheets. In the example of the invention herewith illustrated I have shown a mechanism adapted to form a quarto or eight-page signature comprising two accumulated and folded sheets although it will be understood that the principles of my invention may find embodiment in other forms and that particular mechanisms herein disclosed may be used in other combinations and for otherpurposes. The arrangement which I am about to describe permits a compact organization capable of rapid andaccurate operation. v

My invention will be well understood by reference to the following descrlption taken in conn ctionwith the accompanying drawings, wherein: I

Fig. 1 is a simplified and more or less schematic view showing'in side elevation the series of cylinders by means of which the signature is formed; j

1 is a side elevation of a cam controlling the operation of mechanism as- Fig. immediately above Fig. 1, and is shown as if lifted from 1ts DOIIHZLl POSIlJIOII nearer the reader in Fig. and displaced downwardly to the position shown. Part of the cam is broken away to separate the figure from Fig. 1*.

Figs. 1 and 1 ar similar views showing portions of the camassociate'd with the cylinder appearing immediately above 111' F g. 1-. Fig. 1 is the portion which would be nearer the reader if the cam were in position in Fig.

1. Part ofthe cam in Fig. 1 is broken away- Fig. 4: is a view on a larger scale showing in section the carrier for a sheet-engaging pin and the means for operatlng the same;

, and

sociated with the cylinder which appears in I Fig. 5 is a view on a similar scale showing the tucker blade in section.

from one of the functions which theyperform in the organization(illustrated; The

cylinder 7 at the left may be termed the cutting knife cylinder and it revolves in contact with the cylinder 9 whichmay be termed the cutting die cylinder which in turn contacts with accumulating cylinder 11 which opposes paster cylinder 13. These four cylin ders may all be geared together, the gearing being not herein shown, to rotate at the same surface speed and conveniently as illustrated the cylinders 7 and 13 are twice the diameter of the cylinders 9 and 11. The mechanism shown is designed to form a signature of two leavesor eight pages, each leaf being of a length equalto the circumference of one of.

the smaller cylinders 9 and 11 and to fold these leaves centrally to form an eight-page signature, each page being. of the widthof one-half the circumference of those cylinders.

I will next'describe briefly the operation of the parts, referring particularly to Fig. 1.

The paper in the form of a printed web leads over the uppermost portion of the cylinder 7 and it is clamped against thecylinder 9 by 'me'ans of spring-pressed clamping elements 15 carried by cylinder 7 between which operates a knife 17 cooperating with a'suitable' surface 19 set into roll 9 and which cuts'the web across at the bite of the rolls 7 and 9.

As this action takes place with the immediately adjacent parts in the position shown a series of pins 21, projecting in anon-radial or forwardly inclined direction from the cyl inder 9 a little to the rear of the cutting point, roll into the edge of the" paper at" the rear of the cut. I The raking or non'radial disposition of the pins is such that the pins.

enter the paper smoothly with a clean perfo-' ration and without danger of tearing. The edge of the paper is entrained by the pins and carried around the lower part of the cylinder 9 until the pins arrive at the 3 oiclock position, at which time similar pins 23 carried by the cylinder ll 'roll'into and engage the edge-of the paper. At this time also the wrevolution and another cutter blade 17 will pins 21 are retracted, releasing the paper, the edge of which is carried forward by cyhnder 11. After a half revolution of that cylinder the parts of the mechanism are all in the posi 'tion shown in Fig. 1 of the drawings, the

leading edge of. the paper beingat the 3. oclock position on cylinder lland extending around the upper portion of that'cyl-i-nder and the lower portion of cylinder 9. At this time the cutting cylinder 7 has made a half be brought intoopposition to thecylinder t) will again sever the web, the portion of the paper which is wrapped around the two cylinders 9 and 11 then forming a single separatesheet, and the pins 21 will engage the paper at the further side of the cut and carry it forward to} form the second sheet of the signature. 7 I

After a half revolution of the cylinder 11 from the positionshown the centralportion of what has been called the first sheet is brought t the 3o cloek position oppositepaster cylindQlT .3. and the latterlias made a quarter of a revolution counterclockwise and the. pastor blade 25. will apply paste along the central portion of the sheet to secure the second sheet in position, This paster blade may be mounted toreciprocate radially in cylinder 13, being operated by a cam roll 27 running on a 5;.- sta'tionary eccentric 29 which operates to move the blade 25 outwardly substantially in] the 1e 'GoFClocl; position they are retracted from the paper and suitable stripper means, pres ently to be described, may be operated to release the leading portion. of; the paper from the cylinder. It remains, however, clamped 1 between the cylinders 11 and 13 until the central; portion. of the two sheets arrives at the. center line betweenthese two, cylinders, at

- Whichtimea tucker blade 33carried-by cylinder-11isproj ectedoutwardly into cooperation with suitable female folding mechanism 35 carried on, cylinder '13 to fold the two. sheets centrally intothe form of a signature. This folded signature is thencarried downwardly gripped by mechanism 35 to a feed roll 37 and is. removed fromcylinder 13 by'the strippers-39 working'in grooves in the cylinder and passes to suitable collecting mechanism any desired, kind. 7 v

' I will-next describe the construction of a 7 pin and its carrier and thereafter the method of operating the same and forconvenience I will describe themeehanism of one of the pins 21 which are associated with the cylinder 9.

Referring to Fig. 4, each pin 21, which may be a suitable length of piano. wire and of which a suitable number are disposed in alignment along the length of the cylinder as will be well understood, ismounted in a carrier in the form of a r'od41, the outer end of which slides in a cup or sleeve 43 inset in the face of? the cylinder-and secured by a screw 45, the pin 21 passing through a screw 47 tapped into the endofthe rod which serves as a. chuck to hold the pin, the outer end of the pin projecting as shown through a suitable hole in the bottomof the cup pin tightly .but the latter may nevertheless be manually adjusted, conveniently when the screw is withdrawn, As shown, the rod 41 may be bored to receive the surplus length of pin at the rear. I The inner end ofthe rod 41 may be supported and-guided by a collar 49 pinned thereto and sliding in the opening 51 in the cylinder which receives the rod, this ollar also forming a bearingforjone end of the compressionspring 53' which is interposed between this collar and the end of sleeve 43 and which normally tends to draw the rod to 43.; The screw holes the the right in the fig-urefand retract pin 21 to a position within the circumference of cylin der 9. To operate the pins against the force of the springs 53 to hold the same in projected position to engage the paper theinner ends of the set of rods maybe wiped or cannned by the rounded inner end of] a plunger bar 55 which reciprocates radially in the cylinder. This bar is normally thrust outwardly bythe action of springs 56 (see Fig. 4') under the ends of the bar, but may be moved inwardly toward the left in the figure to move the pin to the position there shown by the action. of suits. able cams. organized at the endsof the cylinder and cooperating; with cam rolls 57 on the ends of the bar 55.

Referring now to F i gs, land 1 ofthe drawlngs, I have shown in Fig.1 the cam 59. which cooperates with the roll 57 shown in Fig. 1 Thiscam is illustrated asif F ig. 1 and Fig. 1 were sections 011. parallel planes through thecompleted mechanism. Cam 59 herein takes the form ofa stationary disc sur-. rounding the shaft 61 ofcylinder 9. and having on its inner face aca-m track 63 cooperlliir lll ating with follower 57 andhavi'ng a'd D essed portion 6 5. of increased radius sopositioned as to permit the outward movement of the follower 57 as pin 21 reaches the 3 oclock position. The springs 53 may then act to retract the pins 21 from; the paper, permitting the paper to be engaged by the pins 23 and carried away by the cylinder 11-.

The pins 23 may be similarly mounted and may be operated by a; plunger 67 similar, to the plunger 55 and having cam followers 69 for-controlling the same. The pins 23, how-- ever, should notbe retracted upon each revolution of the cylinder but only on periodic revolutions, in the present instance, since two sheets are to be accumulated, onevery second revolution. To permit this operation I may utilize a twopart cam as shown in Figs. 1 and 1 and also in Figs. 2 and 3. Referring to these figures, the cam may embody a stationary portion '4 1 organized about the shaft 7 3 of cylinder 11 and having an internal cam t 'aclt 75 shown in full lines in Fig. having a depressed portion 77 analogous to that of the cam 59 but in the 3 oclock'position. The cam 71 also provides a bearing forthe sleevelike flange 79 on a second cain having an internal cam face 81 having a circular portion of the same radius astlie circular portion of cam face 75 but a portion of greater radii s, as illustrated infull lines in Fig; 1 and in dotted lines in Fig. 2, for about a quarter of its extent. The sleeve-like flange of cam 79 may be provided with shrouded gear teeth 83 and is adapted to be driven by a gear 85 to rotate in the opposite direction to the cylinder 11 and atone-half the speed. hen the parts are in the position shown in Fig. 1 and the leading end of the first sheet is engaged by the pins 23 the two parts of the controlling caiii are in the position shown Fig. 1 and the depressed portion of each (3511111111311 masked by the circular portion of the other and the cainroll69 is held in inward position. After a revolution of the cylinder 11 clockwise and a half revolution of cam 79 counterclockwise the portion of the cam track 81 of greater adiiis brought opposite the de-- pressed portion 77 of the stationary caiii traclr 75 as seen in Fig. 2 and cam roll 69, asseen above in Fig. 2, is rel'ei'sed to the latter, permitting tlie'retraction of the pins 23.

Concurrently wit-lithe retraction of pins 23 suitable stripper mechanism carried by the cylinder 11 may be operated to free the sheet and herein 1 have shown such stripper mechanism as operated by the plunger 67. Referring to F 1g. 2, 1 have herein shown a rock shaft 87 carried by cylinder 11 rearwardly of the position of the pins 23 and to this rock shaft are fixed long fing 89, the ends of which extend forwardly past the position or the pins and which are normally loused in suitable recesses 91 in the cylinder. If rock shaft 87 is rotated, these fingers 89 will be lifted, as illustrated in Fig. '2, to strip the paper from the pins and lift it from tlie'surface of cylinder 11 as will be well understood. For this purpose the rock shaft 87 may be provided with gear teeth forming a segment coop :ating with gear teeth on a shaft 93 journalled in the cylinder, from which shafthere extends inwardly an arm 95, the inner end of which acts on a stud 97 extending inwardly from the wiper plunger 07 so that when the latter is released by the cams to be pressed outwardly by its springs (similar springs 56 of bar asshownin Fig. .4) the stud 97 will draw on arm 95 and rock shaft 87 to the position shown in Fig. 2, raising the to be disengaged from the cylinder, approach,

these fingers will'be swung upwardly into proximity to the cylinder so as to engage under the edges oftlie'sheets lifted by fingers 89 to strip the sheets from the cylinder to thesupporting surface beneath. The rock shaft 101 may be operated at a suitable time by meansof the crank arm 103 secured by connecting rod 105 to rocker link 107 having acam follower 109 which cooperates with a suitable cam 111 rotating with'cutter cylinder 7. w r v v Referring again to Fig. 2, as the clockwise rotation of cylinder 11 continues, the'cain,

rolls 1130f the tucker blade. mechanism are released to the depressed portion of the cams,

permitting thetucker blade 33 to be thrust outwardly and to fold the paperbetween the fixed surface 115 and the movable clamp bar- 117 of the cooperating mechanism carried'by cylinder 13 V est extension, and the folding is completed it is again retracted to free the same.

l/Vl ile the tucker blade mechanism might take various suitable forms, I may utilize that claimed in my divisional application, Serial No. 241,371, filed'Dec. 20, 1927, and

shown in detail in Fig. 5 wherein I have shown the cam rolls 113 as mounted on a "radially reciprocating plunger 119 supported and normally thrust outwardly in the cylinder 11 by means of springs 121 mounted as there illustrated. Cain rolls 113 provide for retracting the plungerv against the force of the springs. The tucker blade proper 33 is mounted lengthwise of this plunger in a suitable slot 123, thelower portion of which is of'sufiicientwidth only closely to receive the .lower edge ofthe blade which is retained in position by means of transverse pins 125. The upper portion of the slot provides a clearance atthe following sice of the blade 33 which is supported in the position illustrated in the figure by means of compressionsprings- 127. This arrangement is such as to permit the blade 33 as a whole to yield toward the left in the figure as themechanism as a whole.

rotates to the right and thus its withdrawal from the cooperating mechanism on the cylinder 13 without danger of breakage is facilitated.

Referring to Fig. 2, the blade 33 enters as described between a fixed surface 115 and a clamp blade 117 mounted on a rock shaft 129 and closing against the fixed surface 115. The blade 117 is opened to the positon shown in Fig. 2 when the parts are in the position 7 and asithe blade passes the 3 voclock position, which is its position of greatshown to. provide a clearance so that the tucker blade 33 may roll into position and is closed as it reaches the'9 oclock position corresponding to the full extension of the tucker blade, thus providing for the folding on an arm 133 carried by shaft 129 and adapt.

ed to swing said arm counterclockwise against the action of spring 135. The cam is herein shown as having a toe or rise 137 secured to a stationary disc 139. This rise portion may conveniently be formed of a section" of a flanged ring having a cylindrical flange portion from which is formed the toe of the cam andan annular base portion the segment 1.41

I of which may lie against the side of disc 139 and be adjustably bolted thereto in the manner indicated in the figure.

I have not attempted to show in the drawings the relation of the parts transversely of the machine but it will be well understood that various of the cooperating parts, as, for,

instance, the pins 21 and the pins 23, are placed out of alignment in different planes and that suitable clearance slots or grooves are provided in the various cylinders or parts to permit the passage of elements carried by an adjacent cylinder, as is customary in the art. a
