the art to which it appertains to make and use the same.

The general object of this invention is to improve the construction and increase the capacity and efficiency of machinery for making combination paper board, more especially board composed of one or more phes'mf corrugated'paper or paper board with or Without .one or-more smooth facing sheets. 3

A particular object of the invention is to provlde for corrugating one or more sheets of paper at the same time, pasting them together, ap' lying one or more facing sheets I as desired, rying the composite sheet, and slitting or trimming, scoring and cutting the material into desired lengths, all in one continuous operation.

Another particiilar object is to provide a highly improved travelin drying apparatus for drying the eomposite si cation, and then more particularly pointed.

In said'dra'win s: Figurel is a diagrammatic side view of a machine'ernbodying .my invention.; Figs-2, 3 and 4, taken together, show an enlarged side elevation of the'complete machine. Fig. 2 represents the first or front section thereof, comprising principally the paper supply rolls, 'corrugating and asting mechanisms. Fig. 3-represents a medial section, comprisin prin pally the traveling. dryin apparatus, and,

Fig. 5 is an en arged detail sectional view of the cutting mech- Figs. 6, 7 and 8, taken together, give a top plan view, of the entire machine, said figures representing the subject-matters of Figs. 2, 8 and 4 res ec tively. Figs. 9, 10 and 11, taken together, show a side elevation of the entire machine looking'at the opposite side to that indicated in Fi s. 2, 3 and 4, and representing correspon ing sections of the machine. Fig-.12 is an enlarged vertical section through one of the aste boxes. Fig. 13 is an enlarged detai side view, with parts in section, of a portion of one of the endless traveling drymg belts or a rons. Fig 14 is a top plan view of the su )ject-n'iatter of Fig. 13, partly insection.

At the front of the machine,nlounted in a suitable stand or rack- 1, are a plurality of supply rolls of paper, preferably three rolls designated A, B and C, from which respective sheets of paper'are ai'lapte-d to be unrolled and drawn rearward in alin ement with each other. The shafts 2 on which the said rolls of paper are mounted are shown equipped with pulleys 3, keyed or fast on said shafts, said pulleys being frictionally engaged by weiglhted straps 4 or'stri is of leather, canvas or t e like, acting as bra tees to retard the rotatiom of the rolls and prevent the sheets of gaper from feeding faster than they are rawn through the machine. For insuring the feed of the several sheets of paper in correct alinement, the usual or any appropriate adjusting devices may be provide" In this connection, the illustrated hand-wheels 5 are intended for shifting or adjustingthe rollshafts 2 transversely, while the hand-wheels 6 are intended for ad'usting said shafts axially, the said handeels operating adustbearings.

According to-the illustrated embodiment of m invention, the roll A is intended to 'su p y a'smooth sheet of paper, while the ot er rolls B and U are intended to supply corrugated sheets --to be pasted together and to be faced on one side by the smooth sheet A, also to be faced on the op osite side by a fourth sheet of pa er'hereina ter mentioned, In carryinglout t is urpose, the sheet B from the middle roll of g screws which engage the movable s aft paper is drawn rear-' ward through a corrug'at'ing mechanism,

or intermeshing fluted or corrugated rolls,

' preferably three of such rolls designated 8, 9

rearward the same time.

and 10. The paper sheet B passes successively between rolls 8 and 9 and the rolls 9 and 10, as shown in Fig. 2, wherebythe corrugations in the paper are first formed and then more permanently set. The ressure between the corrugating rolls may e regulated'by adjustingscrews 11 bearing upon pressures rings 12, the latter being seated upon the earings of the topmost corrugating roll, which bearings, together with those of the middle corrugating roll, are vertically movable or adjustable in guide-ways therefor in the stand or rack 7. The rolls may be heated by any appropriate means, as by steam, gas or electricity, but as steam is enerally used by the manufacturers, I have 11 ustrated suitable s'team econnection in Figs. 6 and 9, wherein 13 and 14 designate valved steam sup ly and exhaust pipes in communication wit the hollow trunnions of the several cor-- ru ating rolls, said rolls being also hollow.

ehind the corrugating rol s 8, 9 and 10 is a stand or rack 15 supporting a similar set of corrugating rolls 16, 17 and 18, provided with similar adjusting means (screws 11 and springs 12) and steam supply and exhaust p pes 13 and 14 for heating. The sheet C m the lowermost roll of paper is drawn, past a guide-roller 19 and carriedv between t e corru'gating rolls 16, 17 and 18 in the same manner as the sheet B is carried sheets are drawn rearward and corrugated at Both sets of corrugating rollsare shown longitudinally fluted for corrugatin both sheets B and C transversely of the wi ths of the sheets. But, if desired, one set of corrugating rolls may be annularly orperipherally corru ated for corrugatin the sheet longitudinal for the purpose 0 making two corrugated sheets at one time with'corr-ugations' crossing each other, which would be advantageous in some cases where a very stiff material is required. In case of corru atin one sheet longitudinally, it would be esirable that the sheet should be initiallywider than the other sheet, and the mechanism for making the longitudinal corrugations should preferably be preceded byor contractin appropriate means for athering the paper its widt to accommodate the amount 0 paper taken up by the longi tudinal corrugations.

The smooth sheet A to ether with the two (which latter ass from their res ective 'corrugating' mec anisms over suita ly-disposed guiderollers 20) are drawn rearward over or in contact with a set of paste-rolls 21, which are-arranged in paste-boxes '22- holding the paste, glue or 'ad-' esive mixture for applying to the. sheets of Thus the two.

' with the other sheets.

1 and 3) shown mounted-behind the roll paper. Said paste boxes 22 are shown mounted one above another in a rack .or stand 23 and can. be withdrawn laterally from the side of the machine shown in Fig. 2. Associated with each pasteroll is aparallvl small roll 24 for spreading the paste or g1 ue evenly upon the larger aste-roll, so that it will he applied uniform y'upon the surface ofthe pa er. Above each paste-roll is another sma 1 roll 25 forthe purpose of holding the paper down firmly on the asteroll.

1 The small roll 25 can be lifted 0 when it is desired to withdraw-the paste box. The bearings of the paste-roll 21 and spreadingrolls 24 are contained wholly wlthin the paste-hoxes,'so as to keep the aste from escaping and soiling the mac line. The paste-rolls are also heated, preferably by steam, for which purpose said pasterolls are made hollow and are shown in communication with steanisupply and exhaust pipes 26 and 27 in Figs. 6 and 9, packing-glands being provided between the steam-connections and the hollow journals or trunnions of the pastcrolls.

' On leaving the paste-rolls, the several sheets A, B, C, with adhesive coatings ap-- plied to their respective under sides, are drawn rearward past guide-rollers 28 and between co-acting press-rolls 30, which latter may be slightly roughened or corrugated as circumstances may require. The pressure between the press-rolls 30, in the illustrated construction, is furnished by the weight of the upperroll which bears upon the lower roll, the bearin s of the upper roll being car ried by weights levers 31. Below the pressrolls 30, the sup orting rack oistanll 29 also supports a simi ar set of press-rolls 32, the pur 5 se of which will appear later,

ehindthe press-

rolls

30 and 32, a "fourth supply roll of ppper D is mounted similarly to t erolls A, and C. Said roll D is provided forthe purpose of supplying another smooth facing sheet at the under side of the sheets furnished by the three rolls A, B and C the sheet D being drawn from itsroll and. carried between the press-rolls together Another ro'll E (Figs.

D, and is placed there merelyilrfor the purpose of continuing the feed of t e under facing sheet when the supply of the roll D is ex hausted.

By assing through the press-rolls 30, the

severa sheets 01'' plies of paper become ressed andstuck together, the paste or ad esive mixture havingbeen applied to the under sides of the sh'eets A, B and C, so that the adhesive coatiii comes between the several confronting .s eets or. plies of paper. .The thick composite sheet orgreen board so formed, indicated by the letter .F, is then drawn rearward through another set of press-rolls 33 (Fig. 3), shown in this instance runs of the belts level and ss7,co7

equipped with pressure-springs 34 and ad justing screws 35. Said press-rolls 33 serve not only to press the composite sheet, but

also to feed it rearward to the traveling driers and to draw the several constituent sheets through the machine.

It will be noted that in practice any one or more of the several sheets can be omitted or dropped from use, sothat it is possible to'run either two'corrugated sheets, or one or more corrugated sheets with a smooth facing on either one or both sides. If it be desired to run only a single corrugated sheet and single smooth sheet together, the lower corrugated sheet C and the smooth sheet from the roll D may be brought through the press-rolls 31 as indicated by 'dotted lines in'Fig. 2. Such modifications as placing the supply-roll D above instead of below the ress-roll 31 and arranging for corrugating tlie sheets A and B instead of B and C, or for corrugat/ing the sheet (7 in advance of the cor'rugating of the sheet 13, and other modifications in the gen- .eral construction and arrangement, would of course'fall ,within the scope of the invention.. g

On leaving the press-rolls 35, thecomposite sheet or green board F passes to and is operatedlupon by a traveling drying apparatusshown in Figs. 3, 7, 10, 13 and 14, which dries the material in transit and while pressing it out fiatwise, therebyavoidin bending and consequent injury to the sti board, and carrying out the drying process as fast as the material is produced and in one continuous operation with the corrugating and pasting processes. Saiddrying apparatus comprises coacting endless'belts or

aprons

36 and 37,. each composed of a series of hollow pans or boxes 38 hinged -or flexibly-connected together so as to move freely around the ends of turns of the belt, but so that the co-acting runs of the two drying-belts or aprons form practically continuous flat surfaces Whichwill hold or press the green board or material fiatwise between them Said hollow pans or boxes are provided on'their ends with pairs of small Wheels or rollers 39,- which bear upon and travel over and around suitable tracks 40 which hold the horizontal guide the belts properly around their turns. Said tracks 40, constituting the supporting and guiding means for the drying belts or aprons, are shown mounted between the uprights 41. Each drying belt is driven from one end-by' lateral spur-wheels.4 2, the-teeth ofwhich ena e .between'the pairs of smallwheels or These endless drying belts heated by steam (or other hdt flui passing the-hollow pans or boxes, the means for w 'ch purpose are shown iii-Figs. 3' and 7,;

rol ers 39 'on the ends of the holloW pans. Adjustable bearings for the-spur-wheels permit adjustment or tension'ing ofthe belts.

or aprons are f circumstances so that t and more clearly in Figs. 13 and .14. At one side of the drying apparatus, substantially midway thereof, a steam supply-pipe 43 is connected by a flexible pipe or hos'e section 44 with one of the hollow pans or boxes of each drying-belt, the length of the hose section 44 being suflicient to maintain connection between the steamsupply-pipe 43 and said hollow box .during the complete circuit of travel of the latter. The said hollow pan or box into which the steam enters may be designated 38. At the opposite side of the drying apparatus, an exhaustpipe 45 is connected by a similar hose section 46 with an adjacent box or pan of each dryin -belt,

which box may be designated 38 T e several hollow pans or boxes are connected in series by short hosese'ctions or flexible pipe connections 47, each coupling one box with the adjacent box, except that there is no such obnnection between the

boxes

38 and 38*. In this manner, the live steam enteringthe box 38 will ass successively through all the boxes and ally exhaust from the box 38"; the incoming steam pushing out the exhaust steam behind it.

As shown in Fig. 14, the flexible connections or hose sections 47 are also arranged alternately at opposite ends of the hollow pans or boxes 38, so that the steam is sure to pass throughout the boxes and heat them' uniformly. The flexible hose connections 47' between the boxes. will bend freely as the drying belts are making the turns, while the hose-

sections

44 and 46 connecting with the steam inlet and exhaust pi es 43 and 45'will follow the drying belts in all positions. The several llOSG'SBOtlOIlS-ITIBY be of rubber, fabric or any flexible material suitable for the pur- Y pose.

The object of the above described drying apparatus is to dry corrugated f paper, or paper board, -mill board or any sti material that cannot properly be bent or warped while. drying,. and for drying the same in transit, or as fast as the material is produced and fed to the drienso as to carry out, the drying process as a continuation of the operation .of making-the material in the green state. The drier is not limited in its useful applications to'the particular machine herein set forth. I

The dr ing apparatus can be arranged horizonta ly,-ve'rtically, or in such other position as the. case may require, and may if necessary be built in one or more sections so that any desired amount of' heat can be secured in the driers at different points. They can be built in such a way-that the first'section would press the paper at different points, I

while the second section would press the paper passed by the firstse ctiomand so on. should require it, the driers could-be'lplaced a short space from eachother e moisture wbuldevaporate freely.

- volving As the material is. delivered or emerges" from the traveling drying belts, it passes between press-rolls 48, which serve to press the sheetand also'to help drag the material through the machine and force it rearward through the slittingand scoring rolls and cutter. Said press-rolls 48, mounted in a stand or rack 49, are shown provided with pressure-springs 50' and adjusting screws 51.

From the press-rolls 48, the material passes between enacting slitting wheels or disk shears 52 and 53, which are for the purpose of trimming or cutting the paper'the desired width or widths as it passes along, and thence between co-acting

soorin wheels

54 and 55 which mark the materia longitudinally so that it will fold readily; The transverse passes under the revolving knife or cutten An adjusting screw 62 permits regulating the pressure of the roll 60. v Y

'lhe numeral 63 denotes the revolving knife or cutter blade, which is mounted on a rotary drum 64, the latter being mounted in the stand 65. Said revolving knife co-acts with a stationary blade 66. The revolving blade 63 is adjustably attached to its drum by bolt and slot conncctioiis'67 as shown in Fig. 5, while the stationary blade 66 is also adjustable by the adjusting screws 68 and bolts 69. The relative s fieer l oij're volution ol' the revolving knife is also adjustable for the purpose cl varying the lengths of out. For this puriose, the drum 64 carrying the reknife is driven from a shaft 70, the latter having fast thereon an" expansible' pulley 71 which is expanded or contracted by means of the hand-wheel 72. Said expansible pulley 71 is driven by a belt 73 from a pulley 74, said belt 73 having sufficient slack to accommodate variations in size of the pulley 71, and such slack being taken up by a suitable adjustable pressure-roll 75. I t is obvious that the expansion and contraction.

of the pulley 71 will vary the speed of rave lution of the knife 63. As the materialis cut into lengths, it falls upon an endless conveyer belt 76 and is delivered thereby upon a' table 77. a i

Thusis completed, in a continuous opera tion, the'suc'cessive processes of corrugating' one or more sheets of paper at a time, running one or more facing sheetsas desired, pasting them to ether, drying the composite sheet or i'naterialin transit and while pressing it out flat, and slitting, scoring and cutting the material into desired lengths.

and maintaining t e f9? on V I the stub" shaft 981s a spur-wheel or gear It is understood that the several nn-rcl'nni isms hereinbefore mentioned are positively driven for the pur ose of feeding the paper roper relative timing of the mechanisms. ower may be applied by any suitable means and the machine may be driven either in sections, or themachine may as a whole be connected with a single source of driving power, the latter being piw ferred. For this purpose I have represiml ed suitable driving mechanism shown in elevze tion in Figs. 9, 10 and 11, and in plan view in Figs. 6, 7 and 8.

In Fig. .9, the numeral 80 dcnoLes a driving shaft from which power is transmitted by a belt 81 to apulleySQ oh a shalt 83, said pnl h* 82 being preferably loose on said shaft 63 and adapted to be looked'thercwith by nit-ans of any suitable clutch (not shown), which clutch may be operated by a starting lever 84, shown in Figs. 2 and 6.

Referring to the first section of the ma-- ohine, comprising the corrugatingmechanisms, paste-rolls and pressrolls, it will be observer. from Figs. 6 and 9 that the shal 'ts ol' the first set of corrugating rolls 8, 9 and .10 are provided with intermeshing gears 85. The' shaits of the second set of rorrugniing rolls- 16, 17 and 18 are similarly prr ividml with intermeshing gears 86. Between the two sets of gears 85, S6, and n'ieshing with om gear of each set, is a large spru- 87 on the shaft 83; whereby power is coinnnnlirated lo the two sets of corrugating rolls.

For driving the paste-rolls ii, the upper and lower pasterolls are driven by chain and sprocket gearing 88 and SS) res wctively from the upper and lower corrugaling rolls tit) press-

and at the opposite side (Fig. 3) said shaft 103 is connected by sprocket and chain gearing 104 with the stub shaft 105 of the spur 42 for the upper drying belt. Similarly, referring to Fig. 10 again, the lower stubshaft 101 is connected by sprocket and chain gearing 106 with a lower shaft 107 which extends transversely below the under dryin belt, and at the opposite-side (Fig. 3) sai shaft 107 is connected by sprocket and chain earing 108 with the shaft 109 of the spur 42 for the lower drying belt. It is noted that there are no axial connections between the spurs 42 at the oppositesides of the drying -'apparatus, this arrangement being necessary in order to permit the flexible hose sections 47 and pipes 44 and 46't0 pass between the driving spur-wheels as the drying belts make the turn.

- The press-rolls 33, shown in Fig. 3, are, as shown in Fig. 10, provided with intermeshe ing gears 110 and driven by a sprocket chain 1 11 from a shaft 112, the latter being driven by a sprocket chain 113 from the shaft 101.

Said shaft 101 (Fig. 10) also communicates power by chain and sprocket gearing 116 to the cutting mechansim shown in Figs. 4 and 8 as follows: The sprocket chain 116 engages a gear or sprocket wheel 117 (Figs. 8 and 11) on the shaft 118. it the op osite end of said shaft 118 is the pulley 74 Fig. 4) which drives by belt 73 the before mentioned expansi'ble and contractible pulley 71. The shaft 70 of said expansible pulley 71 is (as shown in Figs. 8 and 11) provided with a gear 120 meshing with. a gear 121 on the sh aft of the revolving knife or cutter 63.

The slitting rolls and 53 (Figs. 4 and 8) have their shafts provided with inter- .igs. 8 and .11) and are driven by a sprocket chain 123 from a pinion on the shaft of one of the gears 114. From the slitting rolls 122 power is communicated by a sprocket chain 124 to the shafts of the scoring rolls 54 and 55, the latter being also provided with intermeshing pinions 125.

From the scoring rolls, power is communicated by a s rocket chain 126 to the shaft of the press ro 60.

It is understood that the foregoing description of the drying connections is made only with reference to the illustrated mechanism, since, as aforesaid, power may be supplied to the various parts of the machine by an suitable connections.
