To all 'who/m. 'it may concern:

, Be it known that I, JAMES F. CLEARL/a citizen of the United States, residin at Chr ca o, in the county of Cook and tate of Il inois, have invented a new and useful Improvementin Creasing-Machines, of which the following is a specication.

My invention relates to improvement -in machines for creasin or scorlng sheets of cardboard, and the li e, more especially for the roduction of paperbox blanks.

y object is to provide a machine of improved and particularly simple construction which will operate to crease or score the sheets with great accuracy and rapidity.

In carrying out my invention I provlde a pair of coperating scoring-rolls which o er- 4ate u on the sheet transversely of the pat o traveV of tlie latter, a feed-table equi ped with adjustable reciprocating feed-mec anism adapted to advance agd position the sheet between the scoring-rolls, and intermittently ,actuated grilpingfrollers operatively timed to engage an discharge the sheet when the scoring or creasing thereof is completed.

Referring to the drawings-Figlire 1 is a plan view of my improved machine;'Fi 2, a plan view of a section ofthe crease or scored sheet; Fig. 3, a section taken on line 3 in Fig. 2; Fi 4, a broken side elevation of the machine; ig. 5, a broken section taken on line 5 in Fig. 1 and enlarged; 6, a lpers ective view of a bar provided with adjusta le spring presser-fingers; Fig. 7, a perspective view of the feed-table and reciprocating sheet-feeders thereon; and Figs.

8, 9 and 10, enlarged broken sections taken,

respectively, on l1nes-8, 9 and 10 in Fig. 7, an viewed as indicated by the arrows.

11 and 12 are the sides or cheeks -of the machine, and 13, a cross-bar in the position shown. The drive-shaft 14 is journaled toward opposite ends in the cheeks and carries fast and loose pulleys 15.

16 and 17 are, respectivel upper and lower scorinor creasing rol s provided at opposite en s with 'ournals' su ported in bearings in the said c eeks. The journals of the upper roller yrotate in journal-boxes 18 supported on adjusting screws 19. The upper roll is provided with or carries at diametrically opposite sides projecting dies 20 formed, ass 21 between two concave depressions 22. The

lower roll is provided or formed withdia-V own, with a central projection metric-ally opposed projecting dies 23, each presenting parallel projections 24, with l. concave depression 25 between them.

On the shaft 14 beyond the cheek 11 is a gear-wheel' 26 engagm an idle gear-wheel 27 journaled on a stub-s aft on the cheek 11. The roll 16 carries a gear-wheel 28, andthe roll 17, a ear-wheel 29. The gearheels 28, 29 are o? the same size and interm the gear-wheel 29 also meshing with the ldlcgear 27. The rolls thus rotate at exactly the same speed and the dies which they carry c0- operate in the manner indicated in Fi 5.

30 is a lower dischar i roll'journa ed It opposite ends in the ciee s in the position s own. Centrall above the roll 30 is a shaft 31 journaleat o posite ends in vertically movable journaloxes or cross-heads 32 working in uide-openings 33 in the cheeks. The shat 31 carries a pair of upper discharge-rollers 34 which may be adjusted toward and away .from each other on the shaft and fastened in adjusted position. Beyond the cheek 11 the shaft 31 carries a gear-wheel 35 which meshes with a gear wheel 36 on the roll 30. The roll 30 also carries a pinion 37. Between and engaging the gear-wheel 29 and pinions 37 is'an ldlcpinion 38. A shaft 39 journaled in the cheeks beyond the roll 30 is provided near opposite ends with cams 40. At each cheek is a lever 41 fulcrumed at 42 and provided at its free end with a roller 43 riding upon the nd'acent cam 40. The cross-heads or journalboxes 32 rest normally on adjusting screws 19, and the levers 41 carry rollers 44 adapted to bear against the under surfaces of the parts 32.

Resting at its rear end upon the bar. 13 and at its forward end upon legs 45 is a feedtabl-e formed of parallel plates 46, 47 separated by a centra longitudinal guideslot 48. Beneath the adjacent edges of the plates 46, 47 are parallel depending channel-bars 49V forming between'them a guide. Journaled in brackets 5'() on the cheelcs is a rock-shaft 51 provided at its end adjacent i A cned series of openings 56 adapted to receive the wrist-pin at the other end of the connectin -rod.

itting and sliding in the guide formed by the channel-bars 49 are blocks 57 and 5S fixed to op osite ends of a longitudinally movable ro 59. The block 57 is pivotally fastened to one end of a connecting-rod 60 which, at its opposite end, is pivotally connected to the up er endof an arm 61 carried b the rock-sha t 51. Sliding in the guideslbt 48 is a block 62 fitting aroundv the rod r59 and adjustably fastened thereto by means ofl a set-screw 63. The block 62 carries a bar 64 which slides upon the surfaces of the plates 46, 47 and carries asheet-edge-engaglng plate or clip 65 and a scoopin -plate 66. Also in the slot 48 is a block 67 aving an opening through it to receive4 the shaft 59 and adjust-ably fastened to the shaft means of a set-screw 68. The block 67 ca"- ries a bar 69 which slides upon the tabletop, and on the bar is a paper-edge-engaging clip70. In the plate 46 is a transverse slot 71 closed at its under side by a stationary plate 72 and fitted with a filler-bar 73 resting on the plate .72. The bar 73 contains a T-slot to receive the head of a bolt 74 and on the plate is a paper-edge guidebar 75 resting on the surface of the plate 46. The bolt carries a thumb-nut 7 6.` The idebar 75 has a boss 77 on its under side itting a longitudinal recess in the ipper surface 0f the bar 73. Theguide 75 maybe moved toward and away from the slot 48 and tightin adjusted position by means of the thumb-scmw 76. The engagement of the boss 77 with the recesses in the bar 73 maintains the guide at a r'ght-angle to the slot 71 and parallel with tlie 'lot t8. i The machine as hen` 1in lu: :'ated is adapted 'more especially for cor.' 1g or creasing sheets of' cardboard to 1r `:odi ce paper boxblanks, of which two a: i required to form a box, in the well knee n manner.y

Themachine is drive by ower applied to the fast pulley 1i, ai l in t e rotation of the drive-shaft 14 the shaft 51 is rocked to` vibrate the arm 61 ind reciprocate the rod 59. Each throu hcrease twice, and the a r-en a ci 6.1; ihdrod in Ilshc backward movement of the latter a sheet e gaged b the clip 65 will be moved between the rol s 16 and 17 e proper position to receive therst crease or score; the ber carrying the clip 70 Sheet of cartooard as it passes the machine is to be vscored or feeder having the is so adjusted upon being so adjusted alog the rod 59 that inA the next Lbackward nwvement of the latter the sheet will be mov between the rolls 16 and 17 and proper'y pt Yitioned to receive the second crease or score.

\Fastened, against the cheeks 11, 12 are presser-lingers 81.

l at the same s upwardlyV extending brackets 78 carrying a cross-bar 79 above the rear end-portion of the feed-table. In the bar 79 is a longitudinal slot 80 in which are adjustably fastelled .spring presser-lingers 81 by means of bolts having thumb-nuts 82. These presser'fingers bear against the upper surface of the sheet of .ardboard fed into the machine and opel'- ate to holdit steady While the sheet-feeders are fnoving toward the forward end of the feed-table and until the sheet is engaged by the scoring-dies. Thus, the parts bein adjusted as described, when a sheet is p aced upon the table against the guide 75 it is engaged in the first backward movement of the rod 59 by the feed-clip G5 and thrust to the desired extent between the scoring-rolls `v vhile the dies of the latter are turningout of coincidence. AHere the sheet is held by the Asthe companion dies come together in the manner shown, the sheet is creased transversely While the feedclip 70 is moving' under and beyond it.' In the' next backward movement of the rod 59 the clip 70 engages the sheet and thrusts it to proper posltion for receiving the second crease or score., y

The journal-boxes or cross-heads in which the shaft 31 is journaled extend over the rollers 44 upon the levers 41 which ride at their rollers 43 upon the cams 40. In the present construction the cams 40 are rotated eed as the scoring-rolls and the 'upper and ower dischargerolls at, say, twice that speed, and during one complete revolution of the scoring-rolls, While the sheet is bein scored', the cams 40 raise' the levers 41 andg upper discharge-rollers 34 out of contact with the sheet while during the next revolution of the scoring-rolls, after the sheet hasbeen scored, the reduced ortions of the cams pass beneath the ro lers 43 permitting the upper feed-rollers to drop and clamp the sheet against the roll 30, whereby thesheet is uickly discharged from' the machine. It Will-be understood, therefore, that in the present machine a sheet is scored in one revolution of the scoring-rolls and during the next revolution of the said rolls it is dischar ed and another sheet is placed u on the tag describe The holes 55 in the crank52 and holes 56 in the crank 53 permit the connecting-rod 54 to be adjusted to chan e the throw of the rod 59 as desired, to regulate the distance of feed of the sheet in each instance. This ad- 'ustment, with the adjustment of the feedars 64, 69 upon the rod is suliicient to make it possible to operate upon sheets of different dimensions and to place the scores 1n any desired locations on the sheets. By providing suitable cams v4()y and changing the vgearing in a manner which would readily suggest itself to a skilled mechanic, the male to be operated upo'n as i chine may be adapted to score a sheet say four times instead of twice between the discharging operations of the discharge-rollers. lVhen it4 is desired to score a sheet say four times instead of twice, additional feed-bars G9 and attendant parts may be placed upon the bar 59 to o erate in succession in thc manner describe The' modifications described and others may be made without departing from the irit of my invention as. defined by the c aims.

What I claim as new, and desire to secure by Letters Patent, is 1. In a sheet-creasing machine, the combination with rotary, 1ntermitteiitly coperatiug creasing-dies, of sheet-discharging rollers, a feed-table, a plurality of reciprocating sheet engaging and thrusting feeders, on the table, constructed and arranged successively to engage a sheet placed upon the table and advance it between the creasingdies, and actuating means for the said discharging-rollers operatively timed to cause the rollers to engage and discharge the sheet on completion of the creasing operations upon the sheet.
