' To all whom 'it may cori/cern: Y

Be it known that LWILLIAM SPALCKHAVER, a citizen of the United States7 residing at Brooklyn, county of Kings, and State of New York, have invented certain new and useful Improvements in Sheet-Associating Mechanism, fully described and represented in the following specification andthe accompanying drawings, forming a part of the same.

1o The improvements are especially adapted for use in printing-machines where itis desired at times to combine a smaller with a larger sheet, as inthe production of newspapers having a numberof pages that may not I5 be constituted by associating two or more main sheets of the same dimensions.

The invention consists in a mechanism 'whereby a small or supplemental sheet fed onward at an appropriate slow speed is aczo celerated, so as to be delivered to the mechanism carrying the web from which the main sheets are formed at the high speed at which the latter moves, and thereafter move in harmony-with the travelot' said web and sheets therefrom, and iinally become associated with the same, the details and novel features of which are hereinafter particularly set forth.

The invention includes various constructions and combinations of parts, all of which 3o will be explained in the course of the following specification, aided bythe accompanying drawings, in which- Figure 1 is an end elevation, Fig. lla plan view, Fig. 2 a side elevation, and Fig. 3 a sec- 3,5 tional elevation, of a machine embodyingthis invention. vFig. 4 is a longitudinal sectional elevation, on a reduced scale, of the principal parts of a printing-machine with which the present improvements are combined. Fig. 5

4o is a sectional elevation of one modification of the invention. Fig. Gis an end elevation, and

Fig. 7 a side elevation, ofanother modification thereof. Fig. 8 is a side elevation, and

Fig. 9 an end elevation, of another modification. Fig. lO is a side elevation, and Fig. 1l an end elevation, of another modification.

Referring now to Figs. l to 4, one construction and operation of a mechanism whereby a supplemental sheet is so associated with 5o the web, successive parts of which are to comprise `a main sheet 0r sheets, will first be described, then its practical use in connection with a printing-machine will be explained, and thereafter modifications of its structure will be pointed out.

Its carrying-cylinder 21 for advancing the slnall or supplemental sheets is composed of several large pulleys fast upon a common shaft 41, which provide a number o f intervening circumferential openings, in which 6o small bearing-rollers 2 may run with their peripheries coincident with the common periphery of the large pulleys composing the cylinder 21, said bearing-rollers 2 being supported by arms 3, extending into said openings from a common shaft 33, xed to the side frames and preferably pressed to duty by means of springs s, the power of which is adj usted by set-screws t. There are as many of these small bearing-rollers 2 and correspond- 7o ing openings in the cylinder 2l as may berequired, six being shown in the machiueillustrated, and co-operating with these bearingrollers 2 are an equal number of accelerating or driving pulleys 4, each hung in an arm 34 75 from a common shaft 35. From this arrangement it will be apparent that the accelerating driving-pulleys 4 and their (3o-operating bearing-rollers 2 may run independently of the movement of the cylinder 21, and hence at a 8o different surface speed. The sheet-carrying cylinder 21 co-operatcs with a sheet-receiving cylinder 20, to which the small or supplementalsheet is delivered, This cylinder 20 carries the main web, and, as here shown, is of a size adapting it to carry circumferentially two main sheet lengths. It is driven at a normal speed'suited to the manipulation of the main sheets, and the cylinder 21 is geared to it so as to run at an appropriate relatively 9o slower speed.

In the example illustrated the cylinder 2l is so geared as to run at one-half of the speed of the cylinder 20, it being driven by means of a wheel 28 from a Wheel 27 of half its size, 95 that is fast on the shaft 42 of the cylinder 20, and the accelerating driving-pulleys 4 are driven at the same surface speed as the cylinder 20 by means of a wheel 29 on the shaft 42, an intermediate 31, and a pinion 32on the roo shaft of the driving-pulleys 4, and preferably by frictional contact therewith the latter move the bearing-rollers 2 at alike speed, though said rollers may be positively moved, as will hereinafter appear.

Cutting-cylinders 22 23 are arranged to cooperate with the cylinder 21, and they are geared together by wheels 24 25 and to the cylinder 21 by a wheel 26, that meshes with the wheel 24, so that theyrun at like surface speed and in unison with the cylinder 21. They are provided with ordinary cutting devices, adapting them to divide a web transversely into short sheets of `suitable lengths. The cylinder 21 is of a circumferential extent equal to that of the cylinder 20, and hence, as

it runs at one-half the speed of and it is to deliver to thelatter sheets of alength equal to half its circumferential extent, this cylinder is provided with means for receiving and carrying what may be called in that relative sense short or half sheets, and, being circumferentially equal to the length of two such halfsheets, such means are duplicated. These means consist of sets of holding-pins 5 6, that are operated so as to be protruded to impale the leading end of each half-sheet, and thus hold it upon and cause it to travel with the cylinder for a period of time and to be withdrawn,so as to release the sheet when it is to be thereafter acted upon by other mechanisms. These pins 5 6, arranged in longitudinal series, reciprocatein guides bored through the shells of the large pulleys composing the cylinder 21 at as many points as are requisite, and they are pivoted to arms that project from common shafts, as 43 44, each of which is provided with a rock-arm, as 45 46, Whose actuating-stud runs in the slot of a cam 47, fixed to the side frame, by which they are protruded and withdrawn in timely co-operation with the other mechanisms. As these sheet-holding carrying-pins 5 or 6 release the sheet before it reaches a point to be seized by the grippers 12, with which the receiving-cylinder 20 is provided, and said sheet would otherwise have to travel a distance withouta means for controlling it, the cylinder 21 is provided with a number of curved guards S, that extend from the shaft 35 and are sus-` tained coincident with the'periphery of the cylinder, and thus form conductors extending close to the cylinder 20, that guide the head of the sheet to said grippers 12 from the point where the pins release it. It will now b'e understood that a narrow or supplemental web N led between the feeding-pulleys 48 and the cutting-cylinder 22, passed between the cutting-cylinders 22 23, and entered between the cutting-cylinder 22 and the carrying-cylinder 21 will be fed onward and have its leading end impaled by the pins 5, and that as it passes them it will be severed into short sheets by the cutting devices of the cutting-cylinders 22 23. lVhen the head of such short sheet held by the pins 5 is carried between the accelerating driving-pulleys 4 and the bearingrollers 2, itwill be nipped by them and at once partake of their rapid movement, and its holding-pins will be simultaneously withdrawn to permit its onward movement independent of the cylinder 21. This short sheet, thus more rapidly advanced than its carrying-cylinder 21 is moving, will be drawn bodily over the surface of the pulleys composing the carrying-cylinder 21 and be carried into a position to have its leading edge seized by the grippers l2 of the cylinder 20, at which time the said short sheet will be moving at the same surface speed as the cylinder 2 Thus seized, it will be laid upon and caused to move with the surface of said cylinder 20, and, although it occupies but one-half of the circumferential extent ofsaid cylinder, it is so associated with or related to the main web or sheet that it may, while thus carried, be simultaneously therewith subjected to any operation, as printing, that is to be eected upon the main web or sheet length thereof which has been delivered to or is then carried by said cylinder. The next succeeding short sheet upon the cylinder 21 will be slowly brought around by the pins 6 until its head is nipped by the driving-pulleys 4 and bear-l ing-rollers 2, when its holding-pins will be withdrawn and it will be accelerated and be delivered in like manner to the grippers 12 of the cylinder 2O and be carried onto the same half portion of said cylinder 2O that received the preceding sheet, and which will have been cleared for its reception by the passage of the preceding half-sheet from off said surface onward to the other mechanisms. Thus one after another of these shorter or half sheets will be formed at a speed of travel which is one-half of that of the cylinder 20 and be successively delivered onto one end of thecylin der 20, which latter may also receive upon its other end main sheet lengths running at its own speed, and these short sheets will thus be so relatively associated with the main sheets or sheet lengths that are upon or are being delivered to said cylinder that both sets of sheets may be simultaneously printed and carried onward concertedly for further manip` ulation and ultimate combination. This receiving-cylinder 2O maybe the carrier for the web from which the main sheets are to be formed, as is illustrated in Fig. 4. It may be provided with means for receiving and delivering long lengths suitable to form one or more main sheets, with which the short or supplemental sheets are to be relatively associated for such treatment as printing, rendering these main and supplemental sheets suitable to be combined, collected, or folded together to compose a single product.

In further illustration of the advantages of this associating mechanism it is shown in Fig. 4 as practically combined with a printing-machine, which will best be readily understood by a preliminary description of the general IOO ItO

. shown as one of its impression-cylinders.

The type-cylinders 10 30 are each of a length suitable for carrying four forms arranged abreast, or lengthwise of the cylinders, and two forms around them, or circumferentially, thus capacita'tin g each type-cylinder to carry eight forms and to p'rint eight pages at each revolution, and for convenience of this description the columns ofthe forms will be supposed to` run around the cylinders.

The impression-cylinders 20'40 are of the same size as the type-cylinders, and all are geared together,so as to run Vin unison.

Assuming that each type-cylinder is provided with forms to its full capacity, or carries eight forms made upvof two setsl of fourpage forms duplicated circu'mferentially, it will be apparent that when this'printin g mechanism operates upon a main web W of the full width of the machine such wide web will be printed upon one side in passing between the type-cylinder 10 and impression-cylinder 20 and upon the other'side in passing between -the impression-cylinder 40 and type-cylinder per, the main sheet lengths may be reduced in length by folding or be divided by transverse severance and have its two parts superimposed; but in the illustrated practical embodiments of this invention the forms are duplicated circumferentially, so that, the typecylinders being covered with forms, each'revolution of them will print a wide web with two eight-page papers, the pages of which are side by side. This w-ide web, led over guid e-rollers,

` led over a roller to secure register and over two parallel angular turning-bars T B,'where by it is shifted laterally and combined withv the other web as the. two meet and passover the guiding-roller'70, and these superimposed webs thereafter travel over guide-rollers, as S0 90, and pass onto av cylinder 91, which is provided with a cutting-slot that cooperates witha cutting-blade carriedby af-cylinder 92, by which the-combined webs are severed at suitable distances apart to divide them intoA sheets each of' a page length. The su perimposed sets of page lengths of these two narrow-webswhich were combined by the lateral transferenceof one over the otherwill thus constitute two eight-page papers that will pass in succession onto the cylinder 9], and from which they may be delivered flat or be directed to a folding-machine, as will be readily understood by those conversant with this art. In order, however, to combine supplemental sheets with the main sheets in this printing mechanism, the sheetassoci ating mechanism is brought into use, at which time a portion of the type-cylinders 10 30 will b e used for the printing of the main sheet and a`portion'for the printing of the supplemental sheet. Each short 'or half sheet delivered to thecylinder 20, as before described, will, as'is obvious, when the printing-forms are available for that purpose, becarried into printing contact with a portion of the forms on the type-cylinders 10 and 30, which at such time is' used for printing' the supplemental web, as will more clearly hereinafter appear, and the grippers 13 of the cylinder 40, which n control its leading end, will be operated so as to deliver each short or half sheet to the grippers 14 ofthe cylinder 37, which in turn will release the sheet, so that it may pass outward for delivery between the tapes 51- and '52, which respectively run as follows: The tapes 5I run from pulleys 53 for a short distance in lcontact with the surface of the cylinder 37,

then passing over pulleys 54, driven in contact with pulleys 55, and returned over pulleys 56 57 to the pulley 53. The tapes'52 run V around the cylinder 37, over the pulleys 54 and 55, and arereturned around pulleys 58 and 59. These tapes carry each 'short sheet S under* neath the main web W, with which web the short sheets are thus combined oresuperimposed for delivery by the cylinder 91,'which, in order to provide it with a means for combining the supplemental sheet with the associated or two-ply main sheet or product of the main web, is furnished with holding-pins 7, that impale the heads of the sheets as they are received upon this cylinder, and with sheetlifting fingers 9, that underlie the heads of the sheets, and,vibrating at each second revolution of the cylinder 91, throw the leading ends of Athe sheets off from the pins 7 and direct them between the rolle-rsl 6l 62. Considering now that this cylinder 2O is one of the impression-cylinders of the perfecting printing-machine, heretofore described, and that itscompanion type-cylinder 10 (as well as the typecylinder 30) may each carry upon one-half of its length the forrns necessary to print the y main sheet, say, of a newspaper which is to be formed out of the web W and upon theV other Yhalf of its length may carry that por# tion of the forms which are toprint va half IOO IIO

or other relative-sized or short supplemental sheet of said newspaper, which supplemental sheet has been formed out of the web N and delivered to the impressioncylinder 20, it will become apparent that such a machine is capaoitated by the present improvements for the making of a variety of products. In illustration of this and bearing in mind that the type-cylinders lO 30 are capacitated to take on four forms lengthwise and two forms around them, it will be apparent that with proper duplication of the forms and the use of a main web W of full width the printingmachine will produce eight two-page papers or four four-page papers at each revolution of the type and impression cylinders, and if the forms are appropriate two eight -page papers would result at each revolution.

By using a three-quarter web and providing each type-cylinder with six forms constituted of three pages or forms duplicated, each three of which extend over three-quarters of its length, and said forms covering the cylinders circumferentially, it will result that at each revolution two six-page papers will be produced, and if the forms are comprised of appropriate matter these two six-page papers, associated and delivered as one product, will constitute one twelve-page paper at each revolution,and the two eight-page papers, in like manner associated and delivered together, will constitute one sixteen-page paper at each revolution. For some of these products, as two and four page papers, if they are to be delivered singly, the final delivery mechanism will require modification from that shown, as is apparent. In order, however, to produce a ten or a fourteen page paper it will be necessary to introduce what has been called herein a short or supplemental sheet and associate it with the main or larger sheets, and this will also be preferably done in the production of a twelve-page paper. The supplemental sheet will in these illustrative uses of the present invention be one page in lengththat is, one-half the circumference of the form-cylind ers.

In the case of the ten-page paper the typecylinders will carry the forms for the main sheet of eight pages on one-half their longitudinal extent. 'Ihe forms, two in number, will be disposed so that they are side by side lengthwise of the cylinder and two in number end to end around the cylinder; and at the other end of the type-cylinders each will carry a one-page form occupying an appropriate remaining quarter of the surface of the cylinder, this form thus extending longitudinally over one-quarter of the length of the cylinder and circumferentially extending half-way around the cylinder. A two-page web or halfweb will now be supplied as the main web W and a one-page-wide or quarter web as the supplemental web N. In the case of a twelvepage paper the above arrangement will be varied by providing the supplement-sheet ends of the type-cylinders with a two-page form occupying one-half of the surface of said cylinders, both longitudinally and circumferentially, and supplying a two-page-wide'or half web as the supplement-web.

Figs. l and 4 illustrate mechanisms arranged for the production of a ten-page paper. The main or two-page-wide web W, of half the width of the machine, is printed in passing through the type and impression cyl-l inders lO 20 40 30 at one end thereof or at one side of the machine, and this perfected web is led over the rollers 50 60 and over the turners or bars 'IS and transferred laterally a distance of its width, and is thus brought to the other side of the machine as it passes over the rollers 80 90 and is delivered to the collecting-cylinder 91. The leading end of this web when delivered to the cylinder 91 is impaied thereon by its holding-pins 7 and is by them caused to make one revolution with said cylinder, during which it is severed by the cutting devices of the cylinders 91 92 just in advance of the said holding-pins, so that the succeeding pages printed from said web are during the second revolution of this cylinder laid upon the preceding pages, thus forming a two-sheet product, each sheet consisting of four pages superimposed upon said cylinder and forming an eight-page main product.

The one-page-wide or quarter-width supplemental'web is directed between the cuttingcylinders 22 23 and severed by them into short sheets one page in length, `each of which has its leading end impaled upon the pins 5 or 6 of the cylinder 2l, which short sheet is released from the pins as it is brought within the range of action of the driving-pulleys 4 and bearing-rollers 2, which accelerate it, so that its speed is doubled and it. travels at the same speed of' the cylinder 20, and its leading end is seized by the grippers l2 of that cylinder, so that thereafter it will be carried by said cylinder and laid upon that half of its surface 'which is behind said grippers. Thus held it will be carried into printing contact with the one form upon the type-cylinder 10 and be printed upon one side and be transferred to the grippers 13 of the cylinder 40 and be carried by that cylinder into contact with the one from on the type-cylinder 30 and be printed upon its opposite side, thus forming a two-page sheet that will be delivered to the grippers 14of the receivingcylinder 37, which runs at like surface speed with the printing mechanisms, and be released by said grippers, so as to be carried outward by the tapes 5l and 52 and be delivered underneath the mainweb W at the roller 90 with its pages in register with those of the second sheet of the two constituting the main product as said second sheet passes onto the cylinder 91, where it and the supplemental sheet are simultaneously impaled upon the pins 7 of that cylinder and become associated with the preceding sheet from the main web, which has entered upon this cylinder. The

leading ends of this triple-sheet product upon the second revolution of the cylinder 91 are thrown off from the holding-pins by the vibrating fingers 9, and the compound or three-ply product is thus enteredbetween deliveryrollers 61 and 62 and carried off to be properly folded or delivered flat, as may be desired. In this last revolution of the cylinder 91 its cutting device, co-operating with that of cylinder 92, severs the web W a second time, and the operation just described is repeated, a pagelength sheet thus being introduced for association with each two component sheets of the main product as the last of these two pass onto said cylinder 91.

For a fourteen-page paper the forms for the main web will be disposed as in the production of a twelve page paper from two six-pages. papers and the two page supplemental or short sheet will be produced as in the making of a ten-page paper, though in this case the one-page form will necessarily be at one end of each cylinder.

In the modification of the sheet-carrying cylinder 21 shown in Fig. 5 the bearing-rollers 2 of that cylinder, instead of being supported upon arms, so as to constantly revolve in contact with the accelerating driving-pulleys 4, are mounted upon shafts carriedin ears projecting into the cylinder and so that their peripheries protrude through slight openings in the surface of said cylinder, which cylinder in this case has a continuous surface, except where these pulleys protrude; but this surface will be cut away circumferentially in alignment with each of these rollers 2, so that the sheet may not be unduly pressed upon by the driving-pulleys 4, except when the latter have contact with the rollers 2. From slight consideration it will be understood that the short or half sheet impaled upon and carried around with the cylinder by the pins 5 or 6 will, when its head, which overlies the rollers 2, reaches a point Where the accelerating driving-pulleys 4 have contact withthe rollers 2,be nipped between said pulleys 4 and rollers 2, and thus, as its holding-pins are withdrawn, be quickly fed onward at a speed equal to that of the cylinder 20, so as to be seized by the grippers 12 of that'cylinder. In this construction the rollers 2 maybe carried in springseated bearings of ordinary construction, so as to aid in producing a suitable nipping of the sheets between them and the driving-pulleys 4.

In the modification shown in Figs. 6 and 7 the bearing-rollers 2 are enlarged, so as to be of a size equal to the large pulleys which compose the cylinder 21, and they are arranged so as to revolve independently of the pulleys composing the cylinder 21, being driven at a like speed and by surface contact with them of the accelerating driving-pulleys 4. In this construction whenever the head of the sheet carried by the pins 5 or 6, which is the point Where the accelerating driving-pulleys 4 nip sheet is immediately fed onward at a rapid speed by the operation of said accelerating driving-pulleys 4 and bearing-rollers 2. Of course these bearing-rollers might turn upon the shaft 42 of the cylinder 2l; but when they vare driven by surface contact with the drivsaid rollers 2 are preferably constructed of narrow rings, which are made to travel in their circular path, supported upon numerous friction-rollers, as 11, which latter have their bearings in cheek-plates supported by a walllike structure mounted iixedly upon said l shaft 42.

From the operation of the sheet-accelerating devices it will be apparent that the rapidly-moving driving-pulleys 4 need only some .go-operating bearing-surface that may be moved concertedly therewith when the supplement-sheet is to be accelerated, and as this bearing-surface may practically be moved frictionally by the driving-pulleys 4 said driving surface may be embodied in many forms. Instead of depending upon frictional action to secure movement of the said driving-surfaces it is desirable in some constructions to move them positively at the high surface speed corresponding with thatof the cylinder 20, to which the sheets are to be delivered. To accomplish this, suitable gearing will be provided to positively drive the rollers 2, such, for instance, as is shown in Figs. 9 to 11, inclusive. To drive the rollers 2 when the same are supported by arms 3, each of said upon its stud, which pinion 15 isconnected by a train of intermediate pinions 16 17 18 witha pinion 19, that is fast upon the shaft 33,' which shaft carries an outside pinion 38, meshing with the wheel 29 on the shaft of cylinder 21, and vconsequently the rollers 2, as well as the pulleys 4, will thus be positively moved at the same surface speed as theA cylinder 21. arms 3 will be loose upon the shaft 33 and held in place by collars. The'rollers 2 in the ring-form shown in Figs. l0 and ll are provided with means for positively moving them' at the same surface speed as the pulleys 4 and cylinder 21. This is accomplished by providing each of said rings 2 with toothedrims 39, fast to them and set slightly within the periphery of the pulleys constituting the carrying-cylinder 21, and these toothed rims 39 are engaged by pulleys, as 41, fast upon a shaft 63, that isA driven by means of a pinion 64 and an intermediate from the wheel 29 on the cylinder 20. y

The sheet-holding pins of the collectingcylinders 91 might be stationary and the throw-off fingers 9 be wholly depended upon to remove the collected sheets from the pins of said cylinder; but preferably the sheetholding pins will be mounted so as to be simultaneously withdrawn as saidV throw-off fingers are operated, so that the two will consaid sheets, the pins are-withdrawn and the jointly operate to release the leading ends of ing-pulleys 4, as illustrated in Figs. 6 and 7;

In this arrangement the IOO pulleys is provided with-a pinion, as 15, fast the collected sheets as speedily as possible, and thus perfectly eoact at the high speed at which these devices operate. Thus the same shaft which carries the fingers 9 will, as it is vibrated by a cam motion similar to that described with respect tothe pins 5 6, simultaneously withdraw the said pins 7.

Although the cylinder 2l has been described as geared to the cylinder 20, such gearing is not essential, but the cylinder 2l may be run at appropriate speed by any suitable driving means. This cylinder is also described as of the same size as the cylinder 2O and as provided with means for carrying two short sheets. It may, however, be of a size adapted to carry one or any number of small sheets of the predetermined size relative to the main sheet and, of course, be provided with the necessary number of sheet-carrying devices; and the devices for holding or controlling the leading end of the sheets may be pins or grippers, or any equivalent device, as may be desired.

`While it is advantageous to sever the supplemental web into sheets by cutting-cylinders arranged as shown, said cutting-cylinders might be a distance away from the cylinder 2l and the web, partially severed, be led thereto, or if completely severed the sheets thus formed might be conveyed thereto by tapes in the wellknown mannner; or, also, the web might be previously partially transversely severed and wound up in a roll, and thus prepared be led to the pinsof the cylinder 21, a sheet being disconnected from the web by the action of the pulleys 4; but the arrangement shown is preferred, as it is practically an eitective one.
