n. TAYLOR, or nasal ORANGE, NEW JERSEY, ASSIGNOR' roniuniaionn can Numerous other objects and advantages of the invention will be apparent as it is better understood from the following description, which, takenin connection with the-accompanying drawings, discloses a preferred em: bodimentthereof. y 1, Referring tothedra-wings: Figure 1 is a side elevation of the operating parts of a machine in which the present in vention is embodied. I .7 Fig. 2'is a fragmentary front elevation of the improved scoring roller .showing its relative position to other parts of, the scoring apparatus, parts being illustrated in section. Fig. 3 is a view similar to Fig. 2 illustrating. a different adjusted position of the,:i1n-' proved scoring roller parts. I Fig. 4 is a transverse sectional view taken substantially along line of Fig. 3,"p arts being illustrated in elevation. a i Fig. 5 is a fragmentary view ofa blank after scoringby the scoring roller of the present invention when adjustedto form one certaiirpattern of scoring. I r Fig. 6 is a view similar to 5- illustrating adifl'erent scoring pattern.

The machine embodying the present invene; tioncomprises a standard 21 (Fig. 1) adapted to rest upon the floor and to carrya supporting frame 22 in which the operating parts of the scoring apparatus are located;

Supporting frame 22carries a-feeding table 23. extending in a substantially horizontal; plane across the front of the apparatus. Blanks 24 preferablyof sheet material, as for exainple'tinplate, are placed upon the. upper surface oftablei23 in any suitable 'mannr' and are moved along a guide 25' carried by the table 23.. g

,A pluralit of feeding rollers 26 (Figs.-

1, 2 and 4:) are mounted upon and. rQtated by'horizontal shafts 27 journaledinbearings 28 formed in the supporting frame 22. The,

feeding rollers 26 extend through openings.

29' formed in table 23. and project slightly above. the upper surface of the table.

A plurality of scoring rollers are mountedabove the feeding table 23 (Fig. 1) in tandem relation. Said scoring rollers-in the. men emb me t. an, p isa pa allel 1 m roller 31 carried by and rotating with a shaft 32 j ournaled in the frame 22, a scoring roller 33 mounted upon and carried by a horizontal roller shaft 34 (Fig. 4) also mounted for rotation in the frame 22 and a flattening roller 35 mounted upon and rotating with a horizontal shaft 36 j ournaled in frame 22. The shafts 32, 34 and 36 are rotated in synchronism with the shafts 27 in any usual or preferred manner. I Y

Roller 31 is positioned directly above the first feeding roller 26 and these two rollers cooperate to advance the blank 24 along the surface of the feeding table 23 and toward the left as viewed in Fig. 1. Scoring roller 33 is positioned directly above the second feeding roller 26 and these two rollers cooperate to further advance the blank through the apparatus. Roller 35, in turn, ispositioned directly above the third-feeding roller 26 and these two rollers cooperate to further advance the blank over the feeding table 23 and to discharge it from the apparatus. 7

Roller 31 is'provided with scoring edges for engaging the upper surface of the blank 24 as it is passing over the first feeding roller 26 and these scoring edges cut two parallel score lines 37 (Fig. 5) in the blank 24. These lines bound a tearing strip 38 which is thereby set off in the blank 24. Scoring roller 33 is provided with scoring edges, which engage the upper surface of blank 24 as it passes over the second feeding roller 26 and which score a series of diagonal lines 39 and 41 positioned inside of the bounding lines 37. Roller 35 is provided with a smooth periphery which flattens and smooths any irregularities in the previously scored lines 37, 39 and 41 by engaging the upper surface of the blank 24 as it passes over the third feeding roller 26. I "Scoring roller 33 (Figs. 3 and 4) comprises airoller body42 keyed at 43 to the forward end of shaft 34 and a roller head 44 mounted on the shaft. 34 forward of the body 42. Roller head 44 is connected with the body42, a side wall45 of the head engaging a side wall 46 of the roller body. The roller parts 42 and 44 are held in longitudinal position upon the roller shaft 34, being firmly clamped between a shoulder 47 formed on shaft 34 and a washer 48 held by a bolt 49 threadedlysecured to the end of the shaft 34.

Roller body 42 is provided with a scoring die consisting of a plurality of parallel projecting'ridges 51 preferably arranged adjacent. the wall 46 and extending diagonally on the surface of the body, said ridges 51 projecting outwardly from the periphery thereof. Roller head 44 isprovided with a similar scoring die consisting of a plurality of parallel projecting ridges52 preferably arranged adjacent the Wall 45 and extending diagonally on the surface of the head and projecting outwardly therefrom. The scoring dies 51 and 52 upon contacting the upper surface of blank 24 (Fig. 4) press the blank firmly against the feeding roller 26 and score lines 39 and 41 as the scoring roller rotates in synchronism with the feeding roller. A feeding ring or rubber 53 is positioned within a peripheral groove 54 formed in the roller head 44 and this frictionally engages the blank 24 and assists in its movement along the feeding table 23.

It will be evident that varying degrees of angularity betweenthe scoring dies 51 and 52 may be employed to meet conditions appertaining to the individual container to be opened, or the ridges 51 may be disposed parallel to ridges 52 instead of an acute angle as shown and such an arrangement will provide parallel score lines 39 and 41 in the blank. Such a system of scoring is advantageously adapted to a container having a single bounding line 37 and a single line of tearing instead of the parallel lines shown.

To obtain the best results in scoring, projecting ridges 51 and 52 must be accurately made and properly sharpened. Where the ends of such cutting dies come together or lay closely adjacent each other as in the scoring illustrated this die manufacture with the one piece rollers now in use, becomes very diflicult. It is particularly difficult to machine die parts when an acute angle is formed between them as in the case of the diagonal score lines illustrated. By mounting ridges 51 and 52 on separable members as in this presentinvention this machining operation is greatly simplified and greater accuracy of parts is provided.

Provision is made for locating the roller head 44 in one of several definite positions relative to the roller body 42. Ihere is used for this purpose a dowel pin 55 carried by the roller head 44 and projecting beyond its wall 45. Pin 55 is positioned within one of three bores 56, 57 and 58, which are at the same distance from the center of shaft 34 but which are spaced angularly at different distances from each other. In this angular spacing the bore 57 is slightly in excess of 120 from the bore 56 and the bore 58 is slightly less than 120 distanced from the bore 56 as indicated in Fig. 3.

By placing pin 55 in the different bores the scoring dies 51 and 52 are located at different relative positions longitudinal of the tearing strip 38=and this effects the scoring pattern formed by the scoring dies. For example, when the roller head 44 is arranged with its pin 55 in bore 56 of the body 42 (Figs. 3 and 4) the resulting scoring pattern involving the lines 39 and 41 forms a diagonal stagger layout as illustrated in Fig. 6. When roller head 44 is shifted to position its pin 55 in bore 57 (Fig. 2) the resulting score pattern on the blank 24 is a herringbone score pattern, such as is illustrated in Fig. 5. In like manner, positioning pin 55 within bore 58 will produce a scoring roller whose scoring action will result in a scoring pattern similar to that shown in Fig. 6 but differing in the relative positions of the score lines 39 and 41.

This shifting of head 44 relative to'body 42 is permitted by removal of bolt 49 and washer 48 from their clamping position at which time head 44 is slid on shaft 34 sufficiently to withdraw pin 55 from one bore and to insert it into another the head 44 at such a time being turned on shaft 34 into the required position. When located with pin 55 in place, washer 48 and bolt 49 are restored to clamp the parts together. As a further insurance against slipping between the roller parts, there are provided several bolts 61 threadedly engaging the body 42 and passing through elongated shouldered'slots 62 formed in the roller head 44. The head of each bolt 61 when screwed into clamping position engages a shoulder 63 formed in the head about each slot. The elongated form of slots 62 permit arrangement of the bolts 61 regardless of the relative position of roller parts 42 and 43. v

It is thought that the invention and many of its attendant advantages will be understood from the foregoing description, and it will be apparent that various changes may be made in the form, construction and arrangement of the parts without departing from the spirit and scope of the invention or sacrificing all of its material advantages, the form hereinbefore described being merely a preferred embodiment thereof.
