Original application filed June 29, 1912,

' board, strawboard, chipboard, etc. such as is ordinarily used for making paper boxes, picture mounts, calendar mounts, etc, and more especially to provide a mechanism in this machine with which the continuous web of lining or covering paper is cut at the end of each sheet of cardboard.

This and other objects of this invention will be fully illustrated in the drawing, dc scribed in the specification and pointed out in the claims at the end thereof.

.In the accompanying drawings,

Figure 1 is atop plan view of the machine. i i

Fig. 2 is aside elevation of the machine v viewed from the right hand side of the machine.

' Fig. 3 is a sectional elevation on the line 3*3 of Fig. 1 showing the mechanism which the cutting inechanism is operated. a Fig. i is a detail perspectiveview' of the mechanism for cutting the paper covering. Fig. 5 is a sectional elevationof the cutting rolls on the line 5*-5 of Figl.

Fig. 6 is a section through the tripping device on the line 6 .6 of Fig. 3. This application is a division of my prior application No. 706,706, filed in the United States Patent Oflice June 29, 1912.

In the accompanying drawings like reference numerals indicate like parts.

In the accompanying drawings reference numeral 1 indicates the frame of the ma chine which consists of two uprights shown partly in side elevationin Figs. 1 and 3 and in top'plan view in Fig. 2.

At the front of the frame 1 is provided thejfeed table 2upon which the cardboard stock is placed that is to be fed to the machine. Adjacent to this feed :table 2are mounted to rotate the feed rollers'3 and 4 each ,of which" rollers consists of a small shaft having ,at suitable intervals narrow collars placed thereon. "The cardboard "191a Serial N 139,674. i

' stock is fed forward between these narrow collars by the frictional engagement there- Wlt.- i The upper roller Sre'sts loosely inthe bearings by which it is supported so that the weight of this roller rests on the upper surface of the cardboard stock as it passes through between the rollers 3 and 4. As shown in Fig. 1 five collarsare placed upon' each ofthe 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 3 may bedecreased 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 andthe cardboard-which engagementin any case is preferably'just enough to secure proper feeding of thecardboard. 1

Mountedon top of the frame of the machine is the square bar :5 having the spring pressing fingers 6, 6 thereon which bearloOsely against the-cardboard stock as it is an sraa gg nnr oFHC If.

fed-forward. The bearing for the bar 5--is{ split at 7 so that thebar 5 may be rotated to any angular position and clampedther'ein. This is for the purpose of adjusting it to different thicknesses of cardboard.

Next in order are the rollers 8' and9, the

roll 9-being uny-ieldingly mountedin the frame of the machine and the roll 8 being yieldingly mountedin the bell crank levers.

l0 and 11, which levers are pivoted to'brackets that are integral with the frame of the machine, the'lever 10 being shown in Fig.

'3, pivoted at 1.2 onthe bracket 13.

Each of these brackets is provided with an arm that projects inwardly, in which a set screw 14 is mounted which bears against the bell crank 10 by which the angular adjustment of it is secured; A l'aracket 15 is also provided rigid with the frame of the machine to which aspring 16 is connected, which spring in turn is connected :to' the bell crank 10 by which the roller8 is yielda i ingly held inengagement with thefro'ller: 9; Similar mountings forthe roller 10' are pro;

v'ided on both sides of the machinej The roller 8 isprovided with a series of collars preferably four or more in number, all of wh ch are clampedor keyed to the shaft. The roller 8 is provided with two collars 17 and 18 with a tripping device or feed regulator rigidly mounted between them. A detail of this arrangement is shown in Fig. 6 in which the shaft or roller 8 is shown provided with the sleeve 19 having a flange on one end thereof and having a reduced end with a shoulder at the other end thereof. On the reduced end is clamped the collar 20 which collar is preferably set up close against the shoulder.

The collars 17 and 18 are thus mounted to rotate loosely on the sleeves 19 and are held in place thereon by the flanges at one end of the sleeves and the collars 20 at the other end. The sleeves 19 and collars 20 are, of course, mounted to rotate with the roller 8 and not independent thereof. Between the flanges on the sleeves 19 as shown in Figs. 2 and 3 the tripping device 21 is supported. This tripping device consists of a knife blade 22 that is set eccentrically in the flanges of the sleeves 19 and is normally held in the position shown in Fig. 3, in which position it bears against the sheet of cardboard as it is fed through the machine.

On the knife blade 22 are provided shoulders 23 as shown in Figs. 2 and 3. When one sheet of cardboard is passing under the knife blade with the blade resting loosely thereon, the next sheet of cardboard advances, partly overlapping the preceding sheet and is deflected upward by the knife blade so that it comes into contact with the shoulders 23 by which its further forward movement is arrested as shown in Fig. 3.

As soon as the preceding sheet of cardboard has passed the knife blade 22 the knife blade drops down, being urged on thereto by the pressure of the succeeding sheet of cardboard which in turn is urged forward by the rollers 3 and 4.

The knife blade 22 and the roller 8 by which it is carried are rotated by the ad vancing sheet of cardboard until the knife has passed clear around the circle, the initial part of the rotation being secured by the directcontact between the advancing sheet of cardboard and the knife blade 22 and the remainder of the rotation being secured by the frictional engagement between the collars 17 and 18 and the sheet of cardboard. The roller 8 is out of balance, the flange on the sleeves 19 being cut away at 24: in order, to contribute to this result, so that the knife blade 22 will drop quickly and follow the end of the sheet of cardboard around, being impelled thereto-by the frictional engage ment between the loosecollars 17 and 18 and the roller 8 by which the knife blade is carried so that the sheet of cardboard as it advances, being driven by the rollers 3 and 4.

frame of the machine.

any cutting action and is called a knife simply because of its shape which is preferred on account of convenience, the thin edge of it being easily passed between the edges'of consecutive sheets.

On the end of the roller 3 is provided a stud 25, which stud as the roller 8 rotates operates on the lever 26 pivoted at 27 on the The opposite end of this lever is hook-shaped as shown at 28 for a purpose that will now be described.

After leaving the rollers'8 and 9 the cardboard passes between the rollers 29 and 30 which are solid rollers, the bottom roller'30 being positively driven and the upper roller 29 being driven by the contact of the cardboard which is fed between the two rollers.

The paper web 31 which has been previously coated with paste by the mechanism shown in my prior application above referred to, passes over the roller 30 and first comes into contact with the cardboard and adheres thereto between the rollers 29 and 30. Beyond these rollers, the cardboard and the paper pass on together.

Next after these rollers are arranged the rollers 32 and 33 by which the continuous paper web previously pasted to the successive cardboard sheets is cut at the end of each sheet of cardboard. The upperroller 32 comprises a hollow tube having the longitudinal opening 34 therein on the front side of which is the flange 35. The roller 33 is made preferably as a casting, having three longitudinal ribs thereon spaced 120 degrees apartbetween centers, which ribs are connected at regular short intervals by circular flanges, the details of which are shown in Fig. 4.

F astened to one of the longitudinal ribs is the cutting knife 36, which cutting knife engages with the longitudinal recess 34 in the roller 32 for the purpose of cutting the paper web at the end of each sheet of cardboard, or for the purpose of separating consecutive sheets of cardboard that are otherwise connected together by the continuous web of paper 31. The operation of these rolls with their cutting knife is timed -to' occur at the end of each sheet of cardboard. This result is secured as follows:

The rolls 32 and 33 are spaced from the knife blade 22 of the tripping device 21 by a distance which is sufficient to allow the cam 25 to trip the lever 26 and secure the rotation of the rollers 32 and 33 from the position shown in Fig. 3 to the position shown in Fig. 5 during the interval elapsing from the time that the end of the sheet of cardboard passes the tripping device 21 until it reaches the position of the knife 36 in Fig. 5. The stud or cam 25is adjusted upon the roller 3 so as to have a delayed action. on the lever 26, and this in connection with the distance through which the knife 36. must travel from the position shown in Fig. 3 to that shown in Fig. 5 is sufficient to cause the knife to act on the paperat'thef 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 the thickness of the knife blade 22 of the tripping device 21.

The roller 33 is driven by thefriction clutch 37 the outer member of which is positively driven by the chain 38 from the sprocket 39. The inner member of the clutch 37 is driven by frictional contact with the outer member which is held in contact therewith by means of theexpansion spring 40. The hook-shaped end 28 of the lever 26 is normally held down in'engagement with the disk 41 by means of the tension spring 42. The disk 41 has a shoulder 43 thereon by which the hook-shaped end 28 of-thelever 26 can engage it to arrest the motion of the roller 33 upon the completion of each revolution thereof, so that the roller 33- will rotate but one for each sheet of cardboard that passes thereover or but once for each time that the tripping device 21 operates through-the roller, 8 to trip the lever 26. The cutting effect of the rolls 32 and 33 is increased by mounting the roller 32 on bearings that are slightlyeccentric thereto, the eccentricity being so located as to crowd therollers together when they are in the position shown in Fig. 5.

The cutting and feeding rolls of this machine are driven by the gear 44, which gear is mounted to rotate in the: framel of the machine. Integral with the gear 44-is the sprocket gear 39, which drives the sprocket chain 38. The sprocket chain 38 drives a sprocket 45 which is integral with the outer members of the clutch 37 through which the cutting roll 33 is driven. The cutting-roll 33 is provided with a pinion 46 which meshes with a pinion 47 on the end of the. roll 32 by which the rolls 32 and 33 are driven in unison; The gear 44 meshes'with the-pinion .48, which pinion drives the roll 30.

On the shaft of the roll 30 is mounted, the sprocket wheel '49; which drives a sprocket chain 50 which chain engages with the sprocket'wheel 5.11 011 the roll 9' and the sprocket wheel 52 loosely mounted ,on the roll 4, the motion of this sprocket wheel being communicated. to the, roll- 4 through a ,frictionclutch 53, the parts of which are yieldingly held together-by the spring 54 which is compressed by'the hand wheel 55. This handwheel has threaded engagement with the 'end: Of" the roll 4 by. which the spring may be compressed and the friction of the clutchregulated at will. v V Y The rollers 3,-8 and'29 are driven solely by frictional contact with the cardboard stock passing through the machine.
