In the accompanying drawings like referj ence numerals referto like parts.

In my machine is included mechanism for supporting the paper roll, mechanism for applying paste or glue to this paper roll, mechanism for feeding the paper from vthis roll to the machine in contact 'with sheets of cardboard, mechanism for cutting the web of paper at the end of each sheetof cardboard, and means for driving a heating roll so that the paper and cardboard will be firmly pressed together and caused Ito adhere one to the other.

There is also included in the machine mechanism for separating the upper roller from the lower roller of cach pair and mechanismfor feeding the paper out of contact with thel pasting roll operating in connection `with the mechanism for separating the rollers of each'pair. 'p

The machine Aalso includes feed regulating mechanism by which the sheets of cardboard are fed consecutively to the machine.

In the accompanying drawings referencenumeral 1 indicates the framework of the machine, which consists of two uprights Patented oet. ae, ier?.

shown in side elevation in Figs. 2 and 3 and wihich are irmly bolted together in any suitable manner.

At the bottom of the machine at the rear end, vis mounted the roll of 'paper.2. This roll of paper is supported on the shaft 3, which shaft carries thereon the cones 4 and 5, which cones may be either round or square and which cones engage with the interior of the tube on which thepaper is wound.

`Mounted on the shaft 3 are the sleeves 6 and 7, each of which sleeves carries therein the set screws 8 and 9. Each of the sleeves. is threaded at 10 and 11, which threaded portion of the sleeve extends into a recess in the cones 4 and 5. On this threaded portion of thgsleeve eis mounted to turn a

collar

12 and 13. The sleeves 6 and 7 are clamped in place by the set screws 8 and 9, after which by turning the

collars

12 and 13 the cones 5 and 4 can be forced rmly into engagement with the roll so that the roll 2 and the shaft 3 and the parts interposed therebetween will all turn in unison.

Mountedon each of the frames 1 are the

brackets

14 and 15, whichbracketsare pivotally mounted on the studs 16 and 17, these brackets being oppositely placed on the machine to each other and being similar in shape symmetrically reversed `to each other. Each of these brackets comprises a web 14a and 15a, in which webs at thebottom are( placed bolts 18 and 19, which bolts engage with suitable openings in the frames, by which the brackets are held in the position shown in Figs. 1 and 2. These bolts can be disengaged from the openings and the brackets can be rotated to the dotted line position shown in Fig. 2. In traveling from the full line to the dotted line position, the pins 18 and 19 bear against the curved tracks 20 and 21 and engage with the stops 22 and 23 at the end thereof, by which their further movement in that directionv is arrested.

The shaft 3 rests in the bearing at each end thereof, one of which is shown in Fig. 12 at 24. This bearing 24` is integral. with i the bracket and is U-shaped and open at the top, affording opportunity for the shaft to turn loosely therein.

Pivotally mounted on the brackets 14 and i 15 are the jaws 25 and 26 shown in Fig. 2

I which bears directly on the shaft and by vlih the friction on the shaft may be regu- In operation the brackets are first lswung' to the dotted line position shown in Fig. 2, in which position the paper roll is laced in position with the shaft 3.' After t e paf per roll has thus been secured to the brackets, the brackets are rotated to the full line vposition by the

levers

33 and 34, in which side, 'such as is shownl at 32X in Fig. 4, fboth of which pinions are mounted on the same shaft, which shaft can be conveniently operated by the hand wheel 40, bywhich hand wheel the paste'box may be placedrin any desired elevation. The ratchet and pawl 41 and 42 are provided in connection with the hand wheel 40, by which the .hand wheel may be held in position when the desired elevation of the paste box 36 is secured.

Mounted to rotate in the frame of the machine is the coating roll 43. The paste box 36 is elevated until the paste therein comes in contact with this roll. The paper 89 travels in the direction indicated by the arrow in 4 and in so traveling Apasses over the idle roll 44 and the paste roll 43. Between the idle roll 44 and the paste roll 43 is mounted the distributing roll 45 which.

bears against-the paste roll 43 for the purpose of distributing the paste thereon. This roll is mounted at each end in bell cranks 46 and 47, shown in Figs. 2 and 3 respectively.

.The free ends of these belll cranks are connected to the 4frame of the machine by the turn buckles 48 and 49, by which the Contact between the distributing roller 45 and the pasting roller 43 may be regulated, so that the amount of paste carried by theV paste roller 43 may be varied at will. Between the distributing roller 45 and the paste roller 43 is carriedthe rod 50, which rod is mounted in the free end of the arms 51 and 52, byk which it may be raised and lowered, as will presently be described.

Mounted on the frame of the machine is a scraper 53 which bears against the paste roller 43 and keeps the `roller clean. Also mounted in the frame of the machine are the

rollers

54, 55 and 56, against which the upper surface passes idly as it passes toward the pairs of pressing rollers. -The roller 56 is shown in Fig. 11, and is shown therein lLaeaero as provided with helicalv ridges 57 thereon, by which the paper is stretched toward the edges and the wrinkles therein are smoothed out.

On top of the machine are provided a se-` ries of feeding and pressing rollers, which rollers I will now describe.

At the front of the machine is provided theffeed table 60, upon which the cardboard stock is placed that is to be fed to the ma-v chine. Adjacent to this feed table'are the feed rollers 61 and 62, each of? which rollers rconsists of a small shaft having at suitable intervals narrow collars placed thereon, -between which'narrow collars the 'stock is fed forward by frictional engagement. The upper roller rests lobsely in the bearings .-by which it is supported. As shown in Fig. l, live collars are placed upon each of the upper and lower rollers, this number or even more being desirable for heavy cardboard. In working on light cardboard the number of collars on the upper roll may be decreased j and the collars may be moved laterally on the shaft so that each of the remaining collars `will only partially engage with the collars on the lower roll, in this way decreasing the frictional engagement between the rollers and the cardboard, which engagement in anyfcase is preferably just enough' to secure proper feeding of the cardboard.

Mounted in the frame of the machine is the square bar 63 having the spring pressing fingers 64 thereon which bear loosely against the cardboard stock as it is fedA forwardf brackets that are integral with the frame of the machine, the lever 69 being shown in Cboth sides of the machine.

Fig. 9 pivoted at 71 on the bracket 72. Each of these brackets is provided with an arm that projects inwardly, in which a set screw 73 is mounted which bears against the bell crank 69, by which the angular adjustment of it is secured. A bracket 74C is also provided rigid with the frame of the machine, to which a spring 75 is connected, which spring in turn is connected to the bell crank 69, by which the roller 67 is yieldingly held in engagement with the roller 68.'r Similar mountings for the roller 67 are provided on The roller-68 is provided with a series of collars, preferably four or more in number,

all of which areclamped 'to the shaft. The

device or feed regulator rigid with the shaft between them. A detail of this arrangement is shown'in Fig. 10,- iny which the shaft or roller 67 is shown provided with the sleeve 76 having a flange on one end thereof and having a reduced end with a shoulder at the other end thereof. 0n the reduced end is clamped the collar 79, which collar-is preferably set up close against the shoulder. The collar 77 is thus mounted torotate loosely on the sleeve 78 and is held in place by the iange at one end of the sleeve land the collar 79 at the other end. The sleeve 78 and collar 79 are of course mounted to rotate with the roller 67 and not independent thereof. Between the flanges on the sleeves 78, as shown in Fig. l0, the tripping device 80I is supported. rlhis tripping device consists of a knife cardboard is passing under the knife with the knife resting loosely thereon, the next sheetof cardboard advances, partly overlapping the preceding sheet; and is deiiected upward b v the knlfe so that it comes intoK contact with the shoulders-81, by which its. further forward movement is arrested, as shown in Fig. 9. As soon as the precedin lsheet of cardboard has passed the knife the 'knife drops down, being urged on thereto by the pressure of the succeeding sheet of cardboard which is urged forward by the v'blade 80A thatl is set eccentrically in the l ianges of the sleeve 78 and is normally held,-

rollers 6l and 62. The knife and the roller l l 67 by which it is carried are rotated by the advancing sheet of cardboard until the knife has passed clear around the circle, the initial part of' the rotation being secured by the djisrect Contact between the advancing sheet o cardboard and the lmife, and the remain#I der of the rotation being secured by the frictional engagement between the collars` 7 6 and 77 and the sheet of cardboard.V 'The roller 67 is out of balance, the Harige on the sleeve n 78 being cut away at 82 in order to contribute to this result, so that the knife will drop down quickly andfollow the end of the sheet of cardboard around, being impelled thereto by the frictionalL engagement between the YV`loose collars 76 and\77 and the roller 67 by which the knife is carried, so that the sheet of cardboard as it advances, being driven by the vrollers 61 and 62, causes the roller 67 to rotate and bring the knife once more intd engagement:1 therewith. This knife does not f have any ctting action and is called a knife simply because of its'shape which ispreferred on account of convenience, the thin l edge of it being easily passed between the edges 'of consecutive sheets.

On the end of the roller 67 isprovided' a l stud 83, which `stud as the roller rotates opa purpose that will now be'described.

After leaving the rollers V67 and 68 the cardboard passes betweenthe rollers 87 and 'lof the tripping device 80.

88 which are solid rollers, the bottom rollerf being positively driven and the upper roller being driven' by the contact of the cardboard which is fed between the two rollers. The paper web 89 from the roller 2 passes up over the roller 88 and lfirst comes into contact with'the cardboard between the

rollers

87 and 88. Beyond these rollers the cardboard and the paper pass on together.

Next after these rollers are arranged the lrollers 90 and 91, by which the paper is cut at' the end of each sheet of cardboard, the roller which is above comprising a hollow tubehaving the longitudinal opening 92v therein, on the front side of which is the iiang'e 93. The roll 91 is made preferably as a casting, having three longitudinal ribs thereon spaced 120 degrees apart between centers, which ribs are connected at regular short intervals by circular fianges, ythe details of which are shown in Fig. 8. Fastened to one of the longitudinal ribs is -'the cutting' knife 94, which cutting knife engages with the longitudinal recess 92 in the roller 90 for the purpose of cutting the paper at the end of each sheet of cardboard, or for1v the-purpose of separating consecutive sheets of cardboard that are otherwise connected together b y the continuous web of paper. The operation of these rolls with theii` cutting knife is timed to occur at the end of each sheet of cardboard. This result is secured as follows: s i

Ihe rolls 90 and 91 are spaced from the knife 80A of the ,tripping device Y80 by a distance which is sufficient to allow the cam 83 to trip the lever 84 and secure the rotation of the -rollers 90 and l91 froml the position shown 1 n Fig. 9 to the position shown in Fig. 9j* vdurlng the interval elapsing from the time that the end of the sheet of c ardboard i passes the tripping device 8O until it reaches the position of the knife 94 in Fig. 9A.` The stud'or cam 83 is set upon the roller 67 so as to have adelay'ed action on the lever 84 and this in connection-with the distance' through which) the knife 94 must travel from the position shown in Fig. 9 to that shown in Fig. 9A is suiicient vto cause the knife to act on the paper at the end of the sheet of cardboard so as to separate the adjacent edges of the cardboard from each other, which edges are separated from each other approximately by thethickness of the knife Theroller' 91 is driven by the friction, clutch 95, the outer member of which is positively driven byy achain gearing Which tact with the outer member except when it is arrested by the hook shaped end v86 of the lever 84.- The hook shaped end 86 of the lever 84 is normally held down in engagement with the disk 96 by means of the tension spring 97 The disk 96 has al shoulder 98 thereon, by which the hook shaped end 86 of the lever 84 can engage it to arrest the 4motion of the roller 91 upon the completion of each revolution thereof, so that the roller 91 will rotate but once for each sheet of cardboard that passes thereover, or but once for each time that the tripping device 80 operates through the` roll 67 to trip the lever 84. The cutting effect is increased by mounting the roller 90 on bearings that are slightly eccentric thereto, the eccentricity being so located as to crowd the rollers together when they are in the position shown in Fig. 9A.

Next after the cutting rollers are the heating and pressing rollers which are arranged in pairs and any desired number of pairs of them may be provided in the machine, five of such pairs however being shown in the -arrangement illustrated in Fig. 4. These rollers are numbered 99, 100, 101, 102, 103, 104, 105, 106, 107 and 108. The upper rollers of each pair are solid and are allowed to press loosely against the sheet of cardboard as it is fed through, no springs being used to increase the pressing effect, the weight of the rollers being suliicient for this purpose, although springs may be used if so desired. `Each of the lower rollers is hollow and is provided with a burner 109 therein, as shown in Fig. l6, in which gas may. be burned for thel purpose of heating the rollers. If desired the rollers may'be heated by steam instead.

. Each of the upper rollers is carried in adjusting screws 111y are provided by whichy the stirrup may be raised or lowered. By this adjustment each of the upper rollers may be kept normally slightly out of contact with the roller below it, leaving a small amount of clearance between them, which clearance will be varied 'according to the thickness of the stock which is being operated on by the machine, so that the roller in each case will not bear Atoo heavily upon the cardboard but will bear thereon just enough to secure the desired result.

On each side of the machine at the top is mounted `two slide lbars 112v and 113 which bars have cams 114 therein which are lnormally located immediately under the cams so as to be, completely lout of engage-k the crank 117. p ended crank and at the opposite end thereof Laeaavo ment with the cardboard that is passing through the machine and by which the feed of thecardboard will be arrested. By this device the feed of the rollers may be stopped without stopping the machine and vany material which may have adhered to the rollers may be easily removed therefrom. These bars are `operated from the lever 114A which is pivoted on the frame of the machine at 115. At the free end thereof a link 116 is connected which is in turn connected to The crank 117 is a double has connected thereto a link 118 which link is in turn connected to the crank 119, which crank is keyed to the shaft 120. On this shaft 120 at each end are keyed the forked arms 121 and `.122, which forked arms engage with anti-friction rolls on the

bars

113 and 112, by which the bars are'reciprocated in unison upon the operation of the lever 114A. Keyed to the shaft 120 is the crank 123 y (see at the right of Fig. 1) to which in .turn

Ien

is connected the linkv 124, to which in turn is connected the crank 125 keyed to the shaft 126, on which shaft, are arms 51 and 52 such as are shown in Figs. 2, 3and 4 between which is 'carried the bar 50 over which the paperl travels. When the lever 114A is operated to raise the upper rollers, the bar is also raised to lift the web of paper 89 out of contact with the paste roll 43 so that aste will no longer beY applied to the paper. en the rolls are lifted by the

bars

112 and 113 the feed of the machine will be stopped as follows:

The sheet of cardboard to which the web of paper is partly pasted by the roll 88 will be held back by the web of paper 89, the friction of the lower rollers being insufficient to pull it forward against this resistance. rlFhe web of paper will also be out of contact with the paste roller 43 which can continue to rotate idly. As soon as the lever 114A is thrown in the reverse direction, the upper rollers are lowered in to contact with the cardboard that must be fed i through, the paper web 89 is lowered into contact with the paste roller 43 and the feed of the material and the operation of the machine is resumed.

@n each of the rollers 99 to 108 inclusive a scraping knife 130 is provided, arms 131 being provided on each side of the machine for each pair of rollers on which the scraping hives 130 are lpivotally mounted so as to bear against the roller which revolves against them. Under the rollers 99 to 108 inclusive, l` place the pan 132 which keeps the dirt which may fall down from the rollers from getting to the paper web or to the paste box. y

'llhe various parts of the machine are driven as follows: Mounted to rotate in the frame of the machine is the shaft 135 on which is keyed the pulley 136 and the pinion 1n turn meshes with the pinion 140 which is mounted to" rotate loosely on the shaft 135 which forms a bearing therefor. The pinion 139 also meshes with the pinion 141 on the paste roll 43 and the pinion 141 in turn meshes with the pinion 142 on the distributing roll 45. The pinion 140 meshes with the pinions 143 and 144, by which the rollers 102 and 104 respectively are driven. Meshing with the pinion 143 is the idlevpinion 143a which in turn meshes with the pinion 145 on the roller 100, by which the roller 100 is driven. Integral with the pinion 145 is the sprocket gear 146 which drives a sprocket chain 147 which in turn drives asprocket gear 148, which in turn drives a friction clutch 95 through which the cutting roll 91 is driven. The cutting roll at the far end is provided with a pinion 149 which meshes with a pinion 150 on the roll 90, by which the rolls 90 and 91 are driven in unison. The pinion 145 also meshes with the pinion 151, which in turn meshes with the pinion 152, which pinion drives the roll 88. On the shaft of the roll 88 is mounted the sprocket wheel 153 which drives a sprocket chain 154, which chain engages with the sprocket wheel 155 on the roll 68 and the sprocket wheel 156 loosely mounted on the roll 62, the motion of this sprocket wheel being communicated to the roll through a friction clutch 157, the parts of which are yieldingly held together by the spring 158 which is compressed by/the hand wheel 159 which has a threaded engagement with the end of the roll by which the spring may be compressed and the friction of the clutch may be regulated at will. The pinion 144 meshes with the idle pinion 160 which in turn meshes with the pinion 1614 on the roller 106. The pinion 161 in turn meshes with the pinion 162, which in turn meshes with the pinion 163 on the roller 108. The

rollers

99, 101, 103 and 105 may be driven positively by gears from the lower rollers of the pairs to which they belong, or they may be driven solely by frictional contact with the cardboard stock passing through the machine.

The roller 108 is positively driven by the pinion 163. The roller 108 has keyed thereto the pinion 164 which in turn meshes with a pinion 165 mounted to rotate loosely upon the upper roller 107. A friction clutch 166 consisting of a washer and nut is interposed between the pinion 165 and the shaft of the roller 107, which clutch may be adjusted to secure any desired torque upon the roller 108.

A feed table 60 is provided at the front end of the machine, on which is provided a gage 170 which isadjustable forthepurpose of securing the correct feed of ,the sheets of cardboard throughthe machine. f
