` lMEANS Fon DAMPENING THE scoRsLlNs oF FOLDING-Box B'LANKaLf To all whom, it may concern,.- Beit known that we, FRANK; B. DAv'lDsoN and JOSEPH IWEssoN, citizens of the United States, residing at Marseilles, in the county of Lasalle and State of Illinois, have invented and useful Improvements in Means for Dampening the Score-Lines of Folding-BOX Blanks; and we do hereby declare that the following is a full, clear, and exact. description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

's inventionrelates to a machine for dampening card or straw board sheets used in the manufacture of lmockdown cartons preparatory to scoring the sheets upon the lInes about whichthe walls of the cartons fold, thereby avoiding the tendency ofthe scoring-knives to unduly weakenthe sheets or blanks at'the score-lines. en using paperfor straw board in the manufacture of cartons, it often occurs that the board is so brittle that the scoring-knives act' to break the ibers of the board along the scoringlines to such extent that when the sections of the'blank are folded along such lines the sections break away from each other, thus protlng andscoring press, the latter usually cmbracing a rotative are to 'the subse uent scoring ducing a damaged carton. In order to obviate the liability of breakingthe material o f the' blanks along the score-lines, we propose to-dam en narrow ge acted upon by the scoring-knives,

and thereby soften the surface fibers, so that operation does not break sai bers. Said dampening device p referaby constitutes an attachment to a-cutimpression-cylinder and a cooperating platen, either rotary or reciprocatory, whichcarries the said dampening-surfaces being so located that the dampening areas producedl thereby will register with the scoring-knives of the scoring- Specication of Letters Patent. f Application filed August 7,1905- areas of the sheet whichv scoring-form by.- which the'sheet or blank is scored and cut in The dampening device I into engagement' with the form on the form-carrying member of the press board while the latter is be' Patented June 19, 1906. lSerial Nm 273,186.

lform. Desirably the dampening-surfaces are mounted so' as to be carriedbyrotative move-l lment against the sheet' to be scored. The de- 5 5 `vice is so constructed and arranged that the dampened areas produced thereby -may correspond in number with all ory a less number A than all of the score-lines to be thereafter impressed upon the blank. v

The invention consists in the matters hereinafter'set forth, and vmore particularly pointf ed out in the appended claims.

In theA drawings, Figure 1 is a`- side elevation of a scoring-press of the character-mentioned, showing four: improved dampening attachment appliedvthereto. Fig. 2 is arear view of theparts shown in Fig. 1. Fig. 3 is an end view of a scoring-press providefI 'th a modified form of our attachment. Fig. 4 is a per- 7o spective view of a roller carrying the moisening-surfac'es used in the machine vshown in i 3. n I I First, referring to the form of device shown in F`gs.1.and 2 andthe press to which it is ap- -7 5 plied, A designates the impressioni-c linder, .y land B the reciprocating scoring-form ed of a reciprocating-bed scoring-press. C designates the feed-table over which the sheets are fed to the cylinder, and 1.a designate the gripper-fingers which p the front mar s of the sheets to win the same about timpression-cylinder. The construction of the press constitutes no part of the presentinven.- 'tion and need not be referred to further in detail. The moistening-surfaces of the moistening device shown in Figs. 1 and 2 are carried by a plurality of independently-,operable disks D, which are rotatively mounted on short shafts d, carried by the upper or outer ends of armsD, which are severally and adjustably fixed to a horizontal rod E, extend- `ing between and iiXed'to arms B', extending rearwardly from the side members B2 of the press. Said wheels or' disks D are freely rotatable on their shafts d and are provided lon their peripheries with suitable strips d of absorbent material, as felt, which constitute themoistening-surfaces.' The,'disks D are so mounted as to rotate withv their moisteningsurfaceszin. ,contact'with the strawI or card carried by the impression-cylinder to the scoring-form of the roo j press, thereby moistening the straw or card board along parallel areas, as indicated in dotted lines below said disks in Fig. 2.

' The disks or wheels Dl are rotated from a common source of power by means of belts F, individual to the several whe-els, trained about pulleys D2, fixedv to or integral with said disks, and trained also about pulleys G G, fixed to a horizontal transverse shaft G that is mounted at its ends in arms B, extending rearwardly from the main frame of the press at the sides thereof. Said shaft G is rotated through the medium of a belt g, that is trained about a pulley G2, fixed to the shaft G and trained also about a pulley A', affixed to the shaft a', carrying the cylinder. The supporting-arms D, carrying the shafts d, on which the disks D are mounted', are separately adjustable toward and from the impression-cylinder, whereby either disk and its associated dampening-surface may be thrown out of action. Such adjustment is afforded, as herein shown, by fastening the arms D to the rod E by means of set-screws d2, that extend through sleeves at the ends of the arms surrounding the shaft and impinge against said shaft. In order to throw an arm D rearwardly to carry its disk away from the cylinder, as shown in dotted lines in Fig. 1, the a propriate belt F is loosened or removed and t e set-screw released sufficiently to permit the arm to swing backwardly, after which the set-screw is again tightened.

The dampening-surfaces are supplied with water to moisten the same through the medium of water-pipe I-I, which extends trans'- versely inrear of the cylinder and is supported on arms B5 B5, constituting extensions of the arms B3, Fig. 1. Said wateripe is provided with a plurality of valved discliiargenozzles h, located one over each of the disks orwheels. The proper opening and closing of said valved nozzles permits the dampening medium to be furnished to all or less than all of the dampening-surfaces carried, as desired.

In Figs. 3 and 4 is lshown a modification of the attachment wherein the dampening-surfaces are carried by a cylindrical roller extending from end to end and in rear of the impression-cylinder. In said figures, I designates a moistening-surface-carrying roller,

and i, and i designate the moistening strips.

or surfaces, the former encircling the roller and the latter extending lengthwise thereof. A single or both sets of the moistening-surfaces t i may be employed. If bothV sets be employed, intersecting sets of dampened areas will appear on the blank, which 1n the continued rotation of the impression-cylinder are brought into register and contact with the knives of the scoring-form. Said moistening-surfaces 'i i consist of felt or other absorbent material attached to the roller in any suitable manner. In this form of attachment it is essential that the longitudinal dampening strips or 'surfaces be so disposed and that the roller I be so geared to the operative parts of the press that the longitudmal strips or surfaces shall impress upon the sheet-moistened areas which shall register with the ap ropriate knives of the scoring-form on the ed, or those which are disposed transversely to the ath of reciprocation of the bed. The sha t i2 of the roller I is rotatively mounted in arms i, rising upwardly from and fixed to a shaft i, mounted at its ends in rearwardly-extending arms B of the press-frame. The roller is rotated through the medium of a sprocket-chain J, which is trained about a sprocketulley I on the shaft i2, and a sprocket-whee A2, carried by the shaft a of the impression-cylinder.

We may employ a greater of less number of strips than shown in Fig. 4 and differently located on the roller to accord with different carton-blanks whose score-lines are located at various distances apart. The same arrangement for supplying moisture to the moistening-surface of the roller I may be emloyed except that the nozzles h should be ocated somewhat nearer to each other in order to uniformly distribute the dampening agent to the longitudinal moistening-surfaces i.

Des'irably a suitably-shaped drip-pan K (shown in both Figs. 1 and 3) is located beneath the moisteningsurface to prevent water drip ing therefrom to the reciprocating bed be ow. Said pan is shown in Fig. 1 as supported by means of arms Ii extending rearwardly from the press-frame. In Fig. 3 the pan is supported on brackets 7c, attached to the rearwardly-extending arms B,

We claim as our invention- 1. The combination with a scoring-machine, of means for dampening prescribed areas of a sheet or blank to be scored preparatory to scorin the sheet along said areas.

2. The com ination with a scoring-machine, of dampening-surfaces adapted to be 4 moved into contact with a sheet or blank to be scored along prescribed areas preparatory to scoring the blank along said areas.

3. The combination with a scoring-machine, of dampening-surfaces adapted to be moved into contact with asheet or blank to be scored along prescribed areas preparatory to scoring the blank along said areas, said .dampening-surfaces being constructed to be adjusted to vary the width apart of the dampened areas on said sheet.

4. The combinationwith a scoring-press, including a rotary impression-cylinder, of means for dampening prescribed areas of a sheet or blank preparatory to scoring the sheet along said areas.

5. The combination with a scoring-press, including a rotary impression-cylinder, of ro- IOO IIO
