l application filed August 30, LEl. (No mrdel.)

To all who/72. it vim/y concern:

Be it known that I, STEPHEN D. Tuonnn,

citizenof the United States, residing in the eity of New York, county of New York, and

'. State of New York, have invented certain new and useful Improvements in Sheet-Delivery Apparatus for Printing-lllaehines, fully de-' scribed and represented in the following speci tion, say, ofhalf-sheets, another of whole sheets, and a third one composed of two half or whole sheets, collected and folded together. The invention consists in a primary sheetmanipulating apparatus, which operates upon thesheets received by it, to either simply guide sheets onward, to collect two or more sheets and guide them onward, or to fold single or collected sheets and guidethem onward, with which is combined a secondary sheet-ma nipulati ng apparatus and interposed change gearing, whereby the constantly-maintained speed of the primary apparatus may be transmitted and reduced, so that the secondary apparatus shall run only at the required speed, determined by the product received from the primary apparatus.

The invention also contains other combinations of parts and devices, hereinafter specifieally described and claimed. W This inventionis illustrated by the accompanying drawings, in. which Figure 1 is aside elevation, Fig. 2 a longitudinal sectional elevation, Fig. 3 a plan view, and Fig. 4 an end elevation, of a machine with the mechanisms adjusted to fold and deliver twopage or half sheets. Fig. 5 is a side elevation, illustrating the machine adjusted to fold whole or four page sheets. Fig. 6 isa side elevation, with theframe-work removed, of the same machine,

having its mechanisms adjusted to collect and fold two full or four-page sheets. Figs. 7 and S are side elevations, Fig. 9 a plan view, Fig.

10 an end elevation, and Fig. 11 a longitudinal The cutting-cylinders'20 21 (shown for the.

purpose of rendering the description clear) belong, as is well understood, to the printingmachine, said cylinders being, as is customary, of the same size as the type-cylinder, or amultiple thereof. In the figures of the drawings referredto they are supposed to be of the same size as the type-cylinders, and the male cylinder is provided at opposite points withtwo cutting-blades, 10 11, one of which is adapted to be removed fromits holding-socket, while both may be constructed so as to entirely or only partially sever the web of paper widthwise, as may be desired. therefore divide the web ihto whole or fourpage sheets, and into half or two-page sheets. These cutting-cylinders are geared together by toothed wheels 101 102, so as to revolve in unison, and will be driven by gearing connecting with some properly rotating shaft of the printing-machine. The printed web from the printing-machine, in passing through these cutting-cylinders, is severed or partially severed into whole or half sheets, as the case may be, and thence is guided to the delivery apparatus by means of tapes 22 23, which convey the same onto the rotating carrierA of the primary mechanism of said apparatus. The'upper set, 22, of thesetapes are stretched from pulleys 33 over the upper portion of the carrier A, thence between the pulleys or grooved rollers 40 41, between the pulleys 48 49, over the roller 50, under the pulleys 58, and return thence over the pulleys 59 73. The under set, 23, of these tapes are stretched from the pulleys 34, and return over pulleys 7 4.

The pulleys 33 34 are set just in advance of the cutting-cylinders, and the tapes 22 23 run lightlytogether in a direct line to the periph cry of the carrier A, and the space between the pulleys 74, where the tapes 23 return, and the surface of said carrier A is spanned by conductors 75. A third set of tapes, 24, are

stretched from the pulleys 7 6 over an adjust- Such cutting-cylinders may a ing-roller, 77, and return over weighted pulleys 78. The roller 77 is hung in arms 80, projecting from a rock-shaft that is actuated through a rock-arm, 81, and a rod, 82, from a cam-slot, 83, in the cam-wheel O. This cam is properly shaped, so that it will cause said tapes at suitable periods of time "to be raised into contact with the under surface of the earrierA, as in Fig. 6, and tobe removed from such contact, as in Fig. 2, the pulleys 7 8 being hung on weighted arms, to impart suitable tension to said tapes in all positions of their movement. The tapes 22 23 are all driven from a toothed wheel, 103, on one end of the shaft of the carrier A, with which a pinion, 90, on the grooved roller or pulleys 40, and a pinion, 91, on the shaft of the pulleys 76 meshes, the latter pinion gearing with a pinion, 92, on the shaft of the pulleys 74. The surface speed of these tapes, as well as that of the carrierA, is rendered slightly greater than that of the cutting eylinders 20 21 by reason of the relatively greater diameter of the carrier A over that of the cuttingcylinders, which carrier is caused to make turn for turn with said cutting-cylinders through a train of toothed wheels, 104 105 106 107, the latter of which is on a shaft, 55, which extends across the machine, its wheel 107 meshing with the wheel 108 011 the shaft of the carrier A. The faster" movement of the carrier A causes the travel of the sheets nipped upon its surface by the tapes 22 to be accelerated,

- so as to disconnect such sheets from the web, if only partially severed therefrom, and in all cases to advance the detached sheet rapidly enough to provide a working-space between succeeding sheets. \Vhen both cutters 10 and 11 are adjusted in the cylinder 20,the web will be divided into half or two-page sheets, 'and as the distance from said cuttingcylinders to the carrier A is arranged to accommodate the length of whole or four-page sheets, nippingrollers 30 31 are arranged with the tapes 22 23, so as to nip, carry forward, and detach the first half-sheet from the web while the succeeding'one is yet nnsevered, as is illustrated and explained in Patent No. 197,694, granted to me November 27, 1877.

The nipping-roller 31 is mounted in the frame-work, so that its periphery is in direct alignment with the tapes 22 23, as is shown best in Fig. 6, while the nipping-roller 30 is mounted in arms 85, the carrying-shaft of which is provided with a rock-arm, 86, whereby said rollers may be rocked from the position shown in Fig. 6, or out of contact with said tapes into the position shown in Fig. 2, where it presses or bends the tapes onto the periphery of the roller 31, to cause said tapes to firmly seize the paper passing between them at that point. Tension-pulleys 45, in adj ustable arms, are arranged to take up and relieve the tapes 23, which are too short to stretch, as will the longer tapes 22. This roller 30 may "be secured ineither of the above positions by a thumb-screw passing through the-arm S6 and entering suitable holes in the side frame.

The carrier A is provided with grippers2, (see Fig. 2,) mounted, as is usual, upon a shaft j ournaled in the carrier, and provided with a T-head,one arm of which is pressed outward,

to close the grippers,by a spring-seated rod, 12,

pass thence to the secondary sheet-manipulating mechanism through the pulleys or rollers 40 41, with which curved guides 13 are arranged to cooperate, said guides being fixed on a shaft, 9, and arranged to be adjusted (See Figs. 2, 3, andinto the operative position in circumferential 1 grooves in'the periphery of the carrier A, as shown in Fig. 2, where they are held by an arm, 14, that may be secured to the framework, or to be thrown out of such position, as in Fig. 5. The carrier A is also provided with a folding-blade (here shown to be a rotating folder) consisting of a shaft to which extended blades 4 5 are secured, one or both of which blades may be removable, or some other means provided for throwing one or both of them out of action, as is set forth in Patents Nos. 191,494, 197,694, and 214,066. The proper timely movements of this rotating folder to cause one or both of, its blades to enter the sheet on the carrier A into the nip of the rollers 40 41 is caused by any of the means set forth in Patent No. 191,494, May 29, 1877,- and now so well understood in this art as to need no specific illustration and description here. The purpose of this secondary apparatus is to fold the sheets received into it, and, as shown, is provided with foldingrollers 51 52, with which coact vibrating folding-blades 70 71. The sheets from the carrier A are conveyed into the secondary apparatus by conducting channels or pathways, as follows: The main channel or pathway,intowhich all of the sheets are directed as they leave the rollers 40 41, is principally composed of the upper tapes, 22, a set of under tapes, 25, that are stretched from the roller or pulleys 41 and return over the pulleys 46, and a third set of tapes, 26," that are stretched from the pulleys 47 and return over pulleys 48. The

Ito

space between the rollers or pulleys 46 47 is spanned by switches 42, which are mounted upon a shaft provided with a rock-arm, 16, that is rocked by a connecting-rod, 94, from a cam-slot, 95,- in the cam-wheel O on the shaft 93, which cam is timed so that these switches will alternately occupy the positions shown{in,Figs. 5 and ;1, in the first position the sheets from it intothe firstauxiliary path way, as is shown in Fig. 2. This auxiliary a pathway is .formed, in part, by said, switches.

42, the pulleys 46, and. principally by conductors 62 63,that extendrto pulleys 68 69,

from which pulleys tapes 27 lead outward over the folding-rollers 51-52. A second auxiliary I pathway is composed, in part, of the pulleys 48 and switches 43, butprincipallyby conductors 6O 61. The conductor 60 bridges the space between the pulleys 48 and the pulleys 97, over which latter the tapes 27 after passihg the rollers or pulleys 98, are stretched, so asto continue one side of said channelto and beneath pulleys.

99, from which these tapes 27 extend outward beneath the foldin'g-blade 71, andthey returnover suitable pulleys to the pulleys 68. The entrance to this auxiliary channel or pathway is betweenthe pulleys 48 49, and it is con. trolled by the guiding-switches 43, which are arranged to be rocked into the position shown in Fig. 2,or intothe position shown in Fig. 5.

i In the position of Fig. 2 these switches form,

in partyoneside of this cha11nel-way,whichis continued from them to the pulleys99 by the conductors 61. A third auxiliary channelway is formed ,in part, by the switches 43 when in theposition shown in Fig. 5 by the tapes 22 where they. passover the switches 43, pulleys 49,-roller 50, pulleys 58, and by short 58. Thetapesand their carrying-pulleys and tapes 28, thatrun over the roller50, pass in contact with the pulleys 58, and return around pulleys 57. The space between the pulleys 57 and 99 is spannedon one side by conductors 64 and on the other by conductors 65,the upper endsof which latter reach to the pulleys rollers of Athe main conducting channel or pathway are always driven with the same surface speed as the carrier A, the gearing shown for thatpurpose being the pinions 90 89, by

which the pulleys or rollers 40 41 are geared together, an intermediate, 120, a pinion, 121, on the shaft of the pulleys 46, an intermediate,

122,and a pinion, 123, on the shaft of the pulleys 47. i The tapes 22 and 26 of course drive the tapes28 and the several pulleys androllers over whichsaid tapes pass with a like surface speedby frictional contact.

The folding i mechanisms of the secondary apparatus and thetapes 27,1eading t11ereto,receive their motionfrom the shaft 93 by means of a toothed .wheel, 111, and an intermediate, 112,which1latter gears with the pinion 113 on the. shaft of the pulley 68, which' latter pinion drives the shaft of pulleys 69 by a pinion, 114. The folding-rollers 51 52 are geared together,

soas. to run in unison, by toothedwheels, as

is usual, their motion being derived} by suitable gearing from the shaft 93. The foldingblades .71 are mounted upon a rock-shaft, 79', that is vibrated by motion: transmitted from the counter-shaft 93 through arock-arm,

the carrier A, to the countershaft 93, as is shown in Figs. 1 and 5. This gearing, as arranged in Fig. 1, consists of equal-sized toothed wheels 115 116, the former being secured to the shaft55, carrying the intermediate 107, whichdrivessaid carrier A. In such arrangement all of the mechanisms will run at a uniform speed. As arranged in Fig. 5,the toothed wheels. 115 116 are supplanted by toothed wheels 117 118, the former being one-half the size of the latter, by which arrangement the folding mechanism of the secondary appara tus will be driven at one-half the speed ofthe carrierA and the primary mechanisms.

With its mechanisms adjusted as in Figs. 1 to 4, the apparatus will be adapted to operate upon two-page or half sheets, the dividinglines of which are determined by the action of the cutters 10 11, both of whichare adjusted in operative position. In this arrangement the nippingroller 30 is thrown into operation, as are the guides 13. The grippers 2 are omit ted or thrown out of operation, and the rotating folder is thrown out of action. As the leading end of the web thus severed or partially severed transversely-on a line for making IOO a half-sheet enters into the nip of the tapes 22 23 between the nipping-rollers 30 31 it takes up the fastcr'movement of these tapes and rollers, and as the division-line of the web has then passed through the pulleys 3334, the

latter will keep the leading end of thesecond half-sheet, Y, not yet severed from the web, so that the leading half-sheet, X, held by the nipping-rollers 3O 31, may be advanced to separate such sheet from the web and provide between its tail end and the head or leading end of the succeeding sheet a suitable working-space, as in Fig. 2. Each sheet thus received by the carrier A will be guided from the surface thereof by the guides13 and pass between the rollers or pulleys 40 41 into the main conducting channel or pathway. When the first sheet, as X, enters said channel, the switches 42 will have been rocked into and rest in such a position as not to interruptsaid channel, (see Fig. 5,) such sheet X thus being conducted through said channel and entered into the second. auxiliary channel between the rollers 48 49 under the switches 43, y

which are then fixed in the position shown in Fig. 2, this sheet X thus being conveyed under the roller'99 and outward on the tapes 27.

The second sheet, Y, will be led in like man ner into said mainchannehway; but whenits head arrives at the point occupied by the switches 42, the latter will have been rocked into the position shown in Fig. 2, so as to interruptsaid channel and guide said sheet into the first auxiliary channel, and thence through the rollers 68 69 onto the tapes 27. These sheets X and Y will, in consequence of the distance at which the entrance-points to these auxiliary channels or pathways are separated, it being aha-lf-sheets length, simultaneously enter into such channels, and be conveyed thereby onto the tapes 27, and by the latter be carried outward over the folding-rollers 51 52, so as to arrive simultaneously in proper position (against gages 66, if desired) to be doubled into the nip of such rollers by the concerted descent of the folding-blades 7 O 71', thus being folded in the desired direction, accord ing as such rollers and blades are related to the travel of the sheets.

For folding full sheets, as fourpage sheets, one of the cutting-blades, as 10, will be re moved from the cutting-cylinders, the nipping-rollers 80 31 will be rendered inoperative, the adjustable guides 13 will be dropped down out of the grooves in the carrier A, and the rotating folder, with both of its blades, 4

'5, fixed in place, will be throwninto operation, and the pair of wheels 115 116 of equal size, as in Fig. 1, that drives the cam-wheel O, the slot 95 of which operated the switches 42, and actuated the mechanisms ofthe secondary apparatus, are changed for a pair, as 117 118, (see Fig. 5,) that will make these last-named devices work at but one-half of their former speed. The web will now be severed or par tially severed at-distances a full sheets length apart, and each whole sheet will then be nipped upon the carrier A, and be advanced at anincreased speed, so as to separateconsecutive sheets a working distance apart. Each sheet thus conveyed to the carrier A will be seized by its grippers or pins, as the case may be, or

be simply held onto said carrier by the tapes 22, its leading end hanging free, and when its central part reaches the point occupied by the rollers or pulleys 40 41, it will be creased or doubled into the nip of those rollers by the action of the rotating folder, which will be operated as in Patent No. 171,196, December 14, 1875, so as to protrude one of its blades, 4 or 5, at the proper time to effect such operation. During this operation the tapes 24 may continue to be rocked by the roller 7 7, for the reason that when single whole sheets are folded their leading edges are drawn backward soon enough not to be nipped by said tapes. Each whole sheet will thus be folded transversely through the rollers 40 41, and be conveyed outward by the main conducting channel or pathway, and each alternate sheet be directed by the action of the switches 42 into one or the other of the auxiliary channels or pathways, asthe case may be, and as has been described with reference to the small or half sheets, which, fiat or open, are of the same length as once-folded whole sheets; but it will be observed that though these sheets are relatively of the same length, there is'aproduct of double the number of half-sheets than there is or"- folded whole sheets, in consequence of which the secondary apparatus, having but one-half the work to do, is run at one -half its'former speed. WVhen folded whole sheets are the product, there will also be more space between the succeeding sheet-sX Y, and hence the foremost sheet, X, will arrive at and enterthe pulleys48 49 sooner than the following sheet, Y, will enter between the pulleys '46 and the switches 42, and hence if said foremost sheet, X, is conveyed between the conductors 61 of the second auxiliary channel, it will arrive over the folding-rollers 51 52 out of time with the sheet Y. To effect the simultaneous arrival of both sheets over the'foldingrollers of the secondary apparatus, the switches 43 are adjusted, as in Fig. 5, so as to direct each sheet, as X, passing the pulleys: 48 49 upward through the longest or third auxiliary channel or pathway, intraveling through which sufficient additional travel is caused to compensate for the greater space, and the head of said sheet is caused to arrive at the pulleys 99 simultaneously with the arrival of the head of the sheet Y, which sheet has been intercepted and guided by the switches 42 at the pulley 69, whence results a concerted manipulation of both sheets by the secondary apparatus. The length of these channels or pathways is such that the distance from the nipping-point of the tapes 22 on the pulleys 46 to the nipping-point of the pulleys 68 69, and from the nipping-point of the pulleys 57 58 to the nip of the tapes 27 on the pulleys 99, is about equal to the length of a folded whole sheet, so

that the sheets may be released from the action of the faster-moving devices the instant they are nipped by the slower-moving ones.

In manipulating double sheets, the carrier A of the primary apparatus has it mechanism adjusted so as to convert .it into a combined gathering and folding apparatus, as is set forth in the Patent No. 191,494, whereby it will col.- lect two whole sheets and simultaneously fold the same through the rollers or pulleys 4O 41.

The rotary folder is then adjusted so that it shall operate at each second revolution only of the carrier A, which may be done by removing one of its blades, as in Fig. 6, or otherwisc, as is described in Patents Nos. 191,494,

197,694, and 214,066, and the rocking tapes 24 are continued in operation that is, so that the roller 77 will move them up and into contact with the carrier A, and out of such contact at alternate revolutions of the carrier. The first full sheet, as X, directed to said carrier will make a revolution therewith, during which time the folding-Blade is inoperative, and receive upon it the next succeeding sheet, as Y, as in Fig. 6, the two lying together upon the'surfa-ce of the carrier. During this second revolution of the carrier A the rotating folder is brought into operation, so as to protrude its blade 5 outwardly, as in Fig. 5, and thussimultaneously double or fold the collected sheets X Y upon a transverse line and into the nip of the rollers or pulleys 4041, from which said collected and folded sheets will pass outward into the main channel or but they'might be fixed in the lel with the travel of 'the paper, and the cutfolded transversely they takeup a length equal to a single full sheet thus folded. It will therefore beapparent that but one-half the number of sets of such collected and folded full sheets,as compared with the number'of single-folded full sheets enter the secondary folding apparatus, and consequently that only one auxiliary conductingcl1annel or pathway for the second sheet manipulating apparatus will be used, and this may be either one, also, that one vibrating folding-blade may be omitted or thrown out of action. M

As shown in Fig. 6, the switches 42 are con tinued in operation, for the reason that they are raised, as in Fig. 2, at the proper time, to cause all of the collected and folded sheets'to pass through the first channel or pathway, the entrance towhich is controlled bysaidswitchcs; position shown in Fig.2, if desired.

a The apparatus above described is applicable to fold the sheets of an ordinary newspaper, in which the columns of printed matter run across the machine. In this case the single sheet might represent a two-page supplement,the double sheet represent a four-page or folio sheet, and a quadruple sheet represent a quarto sheet cut apart'at the head, and

the folding above described would be appropriate for such sheets. If the printing'aud folding machines were made of double width, two such sheets could be printed and folded side by side, or rather end to end.

, In the modifications shown in Figs. 7 to 11, and now to be described, it maybe supposed that the columns of printed matter run paralting-cylinders to be of but half the diameter of the type-cylinders and contain but a single cutting device. The sheets enter the series of faster-running tapes 22 23,which, in this case, are not provided with nipping-rollers, and

'pass directly onto the carrier A, that is provided wit-h means for collecting sheets thereon, as is described in Patent No. 213,793, the guides 13 being given the form of switches, as shown in said figures and automatically vibrated at suitable intervals by means of a rock arm, 3, and a rod, 17, that is suitably vibrated by a cam, 35, (see Fig- 8,) said switches, like the guides 13, entering circumferential grooves in the carrier A when rocked forward. In

" this modification the train of gear-wheels between the carrier A and the cutting-cylinders of said roller or mile 7'1 is su Jlied with a l 3 l l gear-wheel meshing with the toothed wheel 103. a p

The guidesor'switches'13 are elongated,- so as to form a portion of the main channel or pathway leading to the secondary apparatus,

" which is continued to the pulleys 46 by stretching the tapes 27 over pulleys 36 to the pulleys 46, thence downward to the pulleys 114, said tapes between the pulleys 46 and 114 taking the place of the conductor 62.

The switches 42 are now rocked to alternately occupy the position shown in Figs. 8 and 10. In the latterposition they continue the main channel or pathway beyond the pulleys 38,whereit is formed by a set of lower tapes, 29, that run from pulleys 47 over pulleys 48 under pulleys 99,

thence outward over" the folding-rollers 51 52,

returning under thepulleys 98 and over pulleys 54, with which tapes an upper set, 32, co-operate. This set 32 run fromthe pul- Above the switches 13 and tapes 27 are conductors 100, a that bridge the space between the pulleys 90 1 and pulleys 37. 1 slightly changed in form, so as to control the entrance-mouth of the first auxiliary channel orpat-hway, which is between the pulleys 46 3,8 in this modification, said switches being leys 37, undertheipulleys 38, overthe pulleys 47, over the pulleys 48, and return around thepulleys 99 and over the pulleys 59.

WVith the tapes 27 conductors 63 coact to form the first auxiliary pathway, while the second auxiliary channel or pathway isformed by the tapes 29 32.- In this modification tapes con-' stituting the auxiliary pathways are given the speed of operation imparted to the carrier A by connecting the wheel 111 through the intermediate112 with the toothed wheel 121, for the size of the wheel 111 is just twice that of the carrier, and it makes one-half as many revolutions in Fig. 7. In this modification the counter-shaft 93. is placed a littlehigher in the machine, and its movements are communieated to the folding-rollers 51 52, and vibrating folding-blades from a second transverse shaft, 150, through the -equal toothed wheels 151 152. The change gear-wheels 115 116, of equal size, and 117 and 118 the former half the size of the latter, areused,as has been hereinbefore explained. Other devices not again explained are the same as are embodied in the preceding description, as their like characters of reference indicate. In operating upon single sheets this modified apparatus has its guides or switches 13 secured with their points entered into the grooves in the cylinder A, as in Figs. 2, 7,, and 11, whereupon each sheet directedto the carrier Awill be guided therefrom out into thesecondary apparatus, the switches 42 operating to direct each alternate sheet into a different pathway, so that I blades may be placed at right angles to the has been heretofore explained. In this operation the secondary sheet-manipulating mech anisms havebeen drivenby equalsizedwheels 115 116, as in Fig. 7. To adjust the mechanisms to operate upon double sheets, the equal-sized wheels 115 116, that operate the switches 42, the tapes, foldingrollers, and folding-blades of the secondary apparatus, are changed for a pair, 117 118, as in Fig. 8, that will make these devices work at but half their former speed, the smaller of these carrying the cam 85, that operates the guides or switches 13, so that they oscillate and cause the collection of two sheets on the carrier A. The pairs of sheets thus collected will be guided by such switches outwardto the secondary sheet-manipulating apparatus, where they will be folded, as has been explained with respect to single sheets, but at which time the operation of the secondary apparatus, which has but half the number of separate sheets to operate upon, isrun at a half-speed, or only at such velocity as is required by the work it is to perform.

It is to be understood that the folding-rollers 51 52 and their coacting vibrating foldingposition in which they are shown herein, so as to impart the foldings to the sheets in the other direction, that one blade may supplant the two blades 71, and that the rollers 51 52 may be two sets or one set elongated; also that the gages 66 may be omitted, if desired, or any other form of sheet-controlling devices or means for properly registering a sheet over folding-rollers may be employed.

It will be manifest from the foregoing description of this delivery apparatus, that it may be modified so as to operate upon sheets, parts of sheets, and sheets multiplied in number, so as to produce great variety of products or folded papers by the operation of one organization of mechanisms, by slight adjust ments of the parts thereof, and that by the use of change gear-wheels between the primary sheet-manipulating mechanisms and secondary sheet-manipulating f 'mechanisms, the great advantage of causing mechanisms to simply run at the speed required by the work they are to perform may be attained.

Having thus described my invention, what I claim is 1. The combination, with a primary sheetmanipulating apparatus, consisting of a carrier, as A, which is provided with means by which it is capacitatedto guide or fold the sheets, of a secondary sheet-manipulating apparatus, to which the sheets are delivered from the carrier A and folded, of interchange able gearing, whereby said secondary apparatus is driven at the same or a lesser speed than the primary apparatus, all'substantially as described. I

2. The combination, with a primary apparatus adapted tofold sheets, of a secondary apparatus adapted to fold the sheets delivered I from the primary apparatus, means for rendering the folding mechanism of the primary apparatus inoperative, means for guiding the sheets therefrom, and means for varying the speed of the secondary apparatus, all substantially as described. V

3. The combination, with a primary apparatus adapted to fold and associate and fold sheets, of a secondary apparatus adapted to fold the sheets delivered from the primary apparatus, means for rendering the associating and the associating and folding mechanisms ot' the primary apparatus inoperative, means for guiding the sheets therefrom, and means for varying the speed of the secondary apparatus, all substantially as described.

1. The combination, with a primary apparatus adapt-ed to associate sheets, of secondary apparatus adapted to fold the sheets delivered from the primary apparatus, means for rendering the associating mechanism inoperative, and means for varying the speed of the secondary apparatus, all substantially as described.

5. The combination, with a pair of foldingrollers and a carrier provided with a folding blade coacting therewith, of a switch or guide, as 13, and means for adjusting the same so that it may be arranged to guide the sheets off from the carrier and permit their being folded, or be removed to admit the operation of the folding-blade, which latter is provided with means for'rendering it inoperative, all substantially as described.

6. The combination, with the primary sheetmanipulating apparatus, consisting of the cylinder or carrier A and its appurtenances, and the secondary sheet-manipulating apparatus, of the main sheet channel or pathway and two auxiliary sheet channels or pathways leading at different points therefrom to the said secondary manipulating apparatus, all substan tially as described. 7

7. The combination, with the primary sheetmanipulating apparatus, consisting of the cylinder or carrier A and its appurtenances, and the secondary sheet-1nanipulating apparatus, of the main sheet channel or pathway and three auxiliary sheet channels or pathways leading therefrom to said secondary sheetmanipulating apparatus, all substantially as described.

8. The combination, with the primary sheetmanipulating apparatus, consisting of the cylinder or carrierA and its appurtenances, and the secondary sheet-manipulating apparatus, of the main and auxiliary sheet-conducting pathways and switches governing the passage of sheets from said main pathway to the auX- iliary pathways, all substantially as described.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
