21 Claims.

This invention relates to a scoring and cutting device.

The following description is specifically directed to a machine for operating upon paper board stock to form creases or scores therein, cut scorings therein, cuts or trimming of the board including mat production.

The device disclosed herein is adapted not only to operate upon paper board and more especially card board but is adapted to operate upon mat, corrugated, or fibre board as well.

It is also adapted to operate upon glass, linoleum, plywood, et cetera, for cutting purposes. It is also adapted to operate upon leather, rubber and cork sheet materialfor cutting or creasing or cut scoring.

A machine of this general character is adapted for use by bookbinders, display studios, art studios, picture frame manufacturers, hardware stores and box manufacturers who fabricate folding, set up, corrugated and/or libre board boxes.

As previously stated, one important field for the device disclosed herein, is in the production of boxes from paper board stock. The box industry heretofore has sold boxes by sample. These require hand fabrication as distinguished from mass production machine fabrication, Heretofore it has been the practice of 'the box designer to lay out the box to be made for sample purposes and then hand crease, out or Score the same in the desired manner and ralong the lines outlined. It will be readily appreciated that such operation is exceedingly tedious and the sample so produced :it involve considerable labor.

The present invention, therefore, is directed to a machine which will reduce the labor item to a minimum, especially for sample production and this reduction is obtained by providing certain 4" attachments so that a paper board box of this general character can be readily fabricated from the sheet stock to form the finished blank ready for setting up, et cetera, into nal box formation.

) 'Ille invention is herein illustrated as of portable character. It may, however, be embodied as a unitary part of a large bench or table or it may be suitably secured thereto, as desired. The invention contemplates the utilization of two different cutting knife structures, as will be more fully pointed out.

The invention contemplates the use of two olifferent creasing constructions, one having a range of capacity from about l2 point board to about 30 point board and the other having a range 0f capacity from about 25 point board to about 50 or 60 point board.

The invention also contemplates the utilization of two bars. One bar is provided with a cutting 5 knife cooperating surface and a 4 point rule capable of association for forming a crease score in paper board of about 30 to 50 point. Another bar is provided with two rules, one a 2 point rule on one side which accommodates 12 to 20 point board, or the like, and the other a 3 point rule on the opposite side which accommodates 20 to 30 point board, or the like. These dimensions, however, and these limits are set forth merely by way of example only.

The present invention is adapted to be readily changed from a crease-scoring, cut-scoring, cutting or trimming device by utilizing the proper creasing tool or cutting knife, as the case may be, and the proper creasing rule or cutting surface for cooperation therewith, as will hereinafter be pointed out.

The invention includes a pair of spaced trackways elevated above the main plane of operation and which trackways support a manually movable carriage, the latter interchangeably receiving one of the aforementioned knives.

The machine also is arranged in its more complicated form to detachably receive an alignment device by which the paper board stock, or the like, to be operated upon may be properly aligned and positioned The paper stock is positioned beneath the trackways and properly positioned or adjusted and then is clamped in said position. The carriage structure is then moved so that the proper knife, whether of creasing or cutting character, cooperates with the previously selected, complementary bar element to form the crease, score, the cut score, or the cut of the desired character and length. The stock, following the same, and upon retraction of the carriage, is released from clamping engagement, readjusted in position and the operation is repeated. It has been found that substantially all parallel creases, cuts, or the like, of the same character, can be most expeditiously effected and then the board turned at right angles and all those of similar character and previously transverse to the carriage elected. If any operations at an angle 4are required, the protractor attachment is utilized and the desired angular lines are followed for cutting, scoring, creasing, or the like.

To insure accuracy of operation, illumination means may be provided. To prevent injury between parts associated in the machine, adjustable stops may be provided, To facilitate interchangeability of knives, the rail structure is elongated or projects beyond the base structure so that the carriage is supported beyond the base structure. The knife structure and associated parts are readily accessible for removing any one of the three different knives and substituting another knife therefor, or in the case of the crease knife, reversing it to provide a different width of crease as will hereinafter be pointed out.

Other objects and features will be more fully pointed out hereinafter in the following description:

The full nature of the invention will be understood from the accompanying drawings and the following description and claims:

Fig. 21 is a top plan View of a portion of the carriage shown in Fig. 20.

Fig. 14-A is a View similar to Figs. 6, 14 and 15 and of the end of a modified form of bar structure.

Herein the term knife does not necessarily mean a blade for cutting and as previously set forth, the term knife is used in its broad sense and includes each of the constructions shown in Figs. 9, 12, 13, 18 and 19.

In the drawings the numeral 20 indicates a A pair of standards 2| at one end and 22 at the opposite end of said base plate suitably support in spaced relation a pair of tracks 23. These tracks are of T-shaped section, as shown most clearly in Fig. 4. They may be provided, if

desired, with reinforcing rib portions 23a-see l Figs. 2 and 4. Herein the two standards 2| are shown connected together as at 2 Ict-see Fig. 4 and the standards 22 may be similarly connected as-at 22a-see Fig. 2. The trackways, as stated, lare of T-shape in cross section and the inwardly directed ledge portion 24 is provided with the inner face 24a and the upper and lower parallel faces 24h.

One rail 24 includes at each end a bumper or resilient stop 24d for carriage engagement. This includes a headed bolt screwed into the rail and having the exposed body portion enveloped by a rubber or like sleeve.

A carriage includes a. transverse portion 25 and at each end, the same terminates in an elongated portion 26. The carriage supports a handle 21 and a knife carrier, as will hereinafter be pointed out. Each arm 23 at each end is bifurcated as at 25u and a shaft 28 pivotally supports in the bifurcated portion a roll 29 that engages the inner face 24a of the adjacent track member.

Adjacent each of the bifurcations and extending vertically therefrom, is an arm 30 and the same terminates in a trunnion 3| that mounts a roller 32. The two rollers 32 in vertical alignment, engage the upper and lower surfaces 24h of the trackway. In this manner, the carriage structure is definitely located and supported by the trackways, vertical movement of the carriage relative thereto being prevented by the rollers 32 and transverse or horizontal movement of the carriage relative thereto being prevented by the rollers 29. These rollers may be of hardened rubber or fibre or any other suitable material.

Extending upwardly from each standard 2| is the arm portion 33, the same being connected together as at 33a.` and including an aperture 33b. Associated therewith and suitably secured thereto is a flexible, tubular extension element 34 terminating in a light stocket 35 mounting a hood type reflector 36 and the light bulbi 31. Current is supplied to the light bulb` through the opening 33h-see Fig. 4-by means of wires, not shown. Thus, the bulb 31 may be directed to throw the light downwardly and forwardly upon the trackways and the area adjacent thereto.

To limit the sliding movement of the carriage to` prevent interference with other mechanism, hereinafter to be described, there may be provided one or more stops and herein one of the same includes a C-shaped slide having the track embracing arm portions 38 and the connecting portion 39. The same is suitably apertured as at 40 and a headed clamp screw having the head portion 4| and the threaded shank portion 42 is adapted to clamp said stop to one of the rails, the central portion 39 constituting the abutment to limit the travel of the carriage.

portion 44.

ybe set forth hereinafter.

Reference will now be had to Figs. 1 and 2. In said figures, the numeral 43 indicates a pressing, libre or rubber mat plate set into the base 20 so that its upper surface is coplanar with the upper surface of the base. One of the tracks and herein the lower track-see Fig. l-is laterally enlarged as at 44. It is provided with a pair of spaced openings 45 enlarged as at 45a. A pair of stems 46 are slidably supported in the openings 45 and project upwardly through the enlargement 45a. A coil spring 41a encircles each stem and has its lower end seated in the enlargement adjacent the junction between the opening 45 and its enlargement 45a, and its opposite end bears on the head portion 46a of the stem. A tubular cap 41 protects the upwardly extending portion of said stem.

Suitably secured to the lower ends of the stems 46 is a clamping plate 48 that lies parallel to the pressing plate 43 and above the same. The paper board or like material which is to be operated upon by the tool carried by the carriage, is inserted between these two plates and is clamped in position by the plate 48.

The means for operating the clamping plate includes a cam member 49 p-ivotally mounted as at 50. Herein said cam member is shown generally of cylindrical form and it is mounted eccentrically of its central axis. A handle member 5l is offset as at 5|a for carriage travel clearance. The handle member terminates in the handle portion SIb. Herein the circular cam 45 is relieved as at 52 and a headed screw 53 has threaded connection as at 54 in the reentrant portion or recess portion 52 of the cam.

As the cam is caused to rotate counterclockwise by handle movement in the same direction to insure downward movement of the plate 48 into clamping engagement, the head of the bolt 53 moves upwardly and if yextreme pressure be exerted upon the cam structure, it will have no further effect then to cause the head 53 to engage the underface of the rail supportingthe cam structure. This is the laterally enlarged It is by this means that the clamping movement is limited to that determined by the adjusted position of the stop element, to- Wit, bolt 53. This, as stated, prevents distortion of the several plates and possible bending of the stems 45.

The cross member 25-see Figs. 4 and -supports the handle 2l' by means of the extension portion 21a, press fitted in the bore 25ct. The handle portion includes a central bore 55 laterally enlarged at` its upper end as at 55a and laterally enlarged at its lower end, as at 55h. A rod 56 is slidably mounted in the bore 55 and the end thereof exposed in the chamber portion 55a is threaded for threaded connection with a finger piece 51 rotatably mounted in the bore 55a and having the threaded aperture 51a to accommodate the threaded end 56a of the rod 5S.

The coil spring 58'is coaxial with the rod 56, lis included in the chamber 55a, and bears against the lower face thereof, and the lower face of the member 51. The purpose of the aforesaid will The lower end of the rod 56 is threaded as at 56h. A plunger member 59 has threaded engagement as at 59a. with the threaded end 56h of the rod 56. It substantially closes and is slidah-ly supported within the enlargement 5512` of the bore 55. Interposed between the upper face of the enlargement 55h and the upper face of the member 59, is the coil spring 60 that normally projects the plunger '59 downwardly in opposition to spring 58.

Extending parallel to the portions 26 and therebetween is the portion 6I. This provides a pair of parallel depending portions or flanges 62 which receive a pivot ring 63 upon which the knife structure is pivotally supported, the tail portion of the knife structure being nestable in the groove or slot between the flanges 62. The flanges 62 are continued upwardly as at 64 and extending across the same is the pivot pin 65 upon which is pivotally supported a cam 66 having the handle portion 67. It will be obvious when the handle portion 61 is turned clockwise, the cam portion 66 engages the adjacent end of the tail of the knife and tilts the tail clockwise on the pivot 63 and thereby elevates the operating end of the knife structure in opposition to the plunger 59 which normally projects downwardly and causes the operating end of the knife structure to engage the material therebeneath.

Whenever it is desired to change the knife structure or remove the same, the member 51 is threaded down upon the rod 56 which, in opposition to spring 5B, elevates the rod 56 and, therefore, plunger 5T in opposition to spring 5B. This relieves the pressure on the knife structure and the pin 63 may be readily withdrawn from the registering openings adapted to receive same in the flange or side faces'62.

In the channel defined by portion 6| and cheeks 62 is secured at 6m a leaf spring 62a having the curved end 65a, which is interposed between the cam portion 65 and the carriage associated knife. This spring includes among its functions that of serving as a wearing plate.

Whenever it is desired to move the carriage without having the operating portion of the knife .structure engage the material therebeneath, the handle portion 63 of the cam 56 is rotated clockwise which causes clockwise tilting of the knife structure to remove the operating element from material engagement. The carriage and knife structure shown in Fig. 2 is illustrated in non-engaging position so far as the operating end of the knife structure is concerned. In Fig. 5 the knife structure is shown in the normal material engaging position.

Reference will now be had to Figs. 1, 3, 4, 6, 'l and 8. The base 20 is provided in its upper face with a groove 68, the latter being provided with an extension 68a for a purpose hereinafter to be described. A bar member, indicated generally by the numeral 69, is positioned therein. 'I'he base supports a locating pin 'I0-see Fig. l-very near the right end thereof and this locating pin is adapted to be received by a recess 1| formed in the bar 69. Since the bar is reversible, as will be hereinafter pointed out, two complementary recesses 'il are provided.

The bar 69 includes the handle portion 'l2 at one end and the same is apertured at 12a. so that the bar when not in use can be hung upon a nail support or the like.

The bar 59 is comprised of two complementary members 69a and 69h that abut each other as at 69C, and are secured together by the nested clamping screws 13. The members 69a, and 69h are provided with a complementary groove formation 14 that nests a rule l5 therein, and the rule is clamped by means of the bolts 13 between the two members 69a and 69h to form the bar. As shown clearly in Fig. '7, the rule 'I5 is of greater width than the rule '16, the former being positioned in the upper face of the bar and the latter being positioned in the lower face thereof in the respective grooves 14;

In Fig. 8 similar numerals of the 100 series indicate a modified form of bar construction. The two bar forming members |69a and |691) include the groove |14 therebetween which receives a rule |15, smaller in width than rule 16. The upper face of the bar structure is provided With an upper groove |140, of material width and seated therein is an upper member |16 which is the cutting strip. The rule and strip are clampingly mounted in the bar structure. When a cutting knife structure is utilized, the strip |16 carried by the bar |69 is exposed uppermost as shown in Fig. 4, and engaged by the knife edge unless a cutscore operation is performed.

The bar illustrated in Fig. 8 is provided with an apertured handle portion in the same manner as bar 69, shown in Figs. 6 and '1, is provided with same.

When crease-scoring is to be performed, either the lower face with rule |15 of the bar |69 will be exposed uppermost or the bar shown in Fig. '1 will be substituted therefor, and either the rule 15 or the rule 16, as desired, will be exposed uppermost. It is noted that rules 15, 16 and |15 all project above the plane of the Abar an equal amount, whereas the upper face of the strip portion |16 is preferably coplanar therewith.

Reference will now be had to Figs. 9y to 11, inclusive. In these figures, the creasing knife is illustrated. Herein the creasing knife includes a body portion 11 and there is provided a hole 18. Adjacent thereto is a bearing portion 19 adapted for engagement by the plunger 59. The hole 18 is adapted to be received by the slip pivot pin 63-see Fig. 5. The opposite face of the body portion is relieved as at for a purpose hereinafter to be described.

The forward end of the creasing knife is grooved as at 8|. It includes an indicator as at 82. This is of appreciable width. The margin 82a indicates the starting position and the margin 82h indicates the stopping position. It will be quite apparent that when the groove 8| is adapted to nest the paper board stock forced upwardly into the same by one of the rule members 15, 16, |15, depending upon which rule is being used and provided further that the proper rule for the proper width of groove 8| is employed, the surfaces Bla adjacent the groove, are bearing surfaces that bear on the material being creased. The opposite end of the creasing knife is similarly but reversely formed and is identical to the end previously described, except that the Width of the slot or groove is different. indicate like or similar parts at this end of the knife.

In Fig. 12 there is illustrated a cutting knife that is adapted to make vertical cuts. In this form of the invention, the numeral 83 indicates the body portion and 84 the tail portion adapted for contact with the cam 66. The numeral 85 indicates an opening adapted to receive the knife supporting pin 63. The numeral 86 indicates an abutment adapted to be engaged by the plunger 59. The forward end of this knife structure is indicated by the numeral 81 and there is provided in inclined relation relative to the longitudinal axis of the knife structure, a recess 88. A closure plate 89 is clampingly associated therewith by means of the clamping member 90 for clampingly retaining a knife blade 9| in the socket 88. 'Ihis knife blade has cutting edges 9|a and 9|b terminating in the point 9|c. The cutting edges Similar numerals of the series 9| a and 9|b are tapered edges, to-wit, oppositely and medianly tapered.

In Fig. 13 there is illustrated a swivel type cutting knife structure. 'Ihe body portion is indicated y by the numeral 92. The opening 93 is adapted to receive the mounting pin or shaft 63. 'I'he tail portion 94 is adapted for contact by the cam 66. The body portion 92 includes the abutment 95 adapted for engagement by plunger 59. The forward portion of this knife structure includes a body portion 96 having a cylindrical bore 91 therein and a clamping screw 98 is adapted to clampingly retain in the rotatively adjusted position the cylindrical member 99. This member is provided with an inclined recess |00 adapted to receive a knife blade member |0|. The complementary clamping member |02 is associated therewith for the clamping retention of the knife blade 0| by means of the clamping screw |03. The knife blade |0| has the beveled cutting edges lllla. and llb meeting in a point |0|c. These beveled faces are of singular character so that the proper clean bevel cut can be obtained. Usually, for mat purposes this bevel cut is about 60 although if desired, any other bevel or inclination may be obtained when desired. This swivel type holder structure may, if desired, be used for all purposes that the knife structure shown in Fig. l2 is utilized. In that event, if desired, the lizi'ife blade 9| may be substituted for the knife In Figs. 14 to 16, inclusive, there is illustrated a modified form of bar, the latter gure illustrating the operation of said modification when applied to the base. In these figures, numerals of the 300 series indicate like or similar parts shown in Figs. 6 and 7, and indicated by the primary series of numerals.

In the bar 369 and in portions 3690, and 369D in opposed and paired relation, are a pair of parallel longitudinally aligned series of threaded v apertures 31|a. In each is a set screw 310a of Allen type. These are staggered in relationship as illustrated in Figs. 14, 15 and 16 so that the ends 3101)' when projected from the bar may y space the bar 369 from the base so that as the rule 315 or 316 wears, the same effective upper rule surface may be maintained, thus delaying rule replacement.

This adjustment also permits the bar to be elevated relative to the base in such instances as a higher rule surface, relative to the base, is desired without the necessity of breaking down the bar and replacing the standard rule with a higher rule. These are but two purposes to which this adjustment is directed.

- In Fig. 14-A there is illustrated a modified form of bar suspension. Herein 469 indicates the body portion provided with the head portion 412 apertured at 412e to receive the inward directed ends 412b of a snap loop 41211..

In Fig. 17 is illustrated a modified form of carriage structure and the same is shown associated with an adjacent rail or track. Numerals of the 400 series indicate parts herein which are like or equivalent to parts illustrated in previous views and indicated by similar numerals of the primary series.

In Fig. 17 the transverse portion of the carriage is indicated by the numeral 425. The portion parallel to the track 423 having the web portion 424 and providing the inwardly directed face 424e and the top and bottom surfaces 424b, is indicated by the numeral 426.

Depending therefrom in spaced relation and 75 "within the rail structure, are ears 4306, each of which mounts the trunm'on or shaft 43| in turn mounting the rollers 432D which engage upon the under surface 424D of the track struc ture. Each projecting end of the portion 426 is slotted as at 426a and mounted on the shaft 428 therebetween is roller 429 that bears against the inner track surface 42411.

A pair of rollers 432b engage the upper surface 42412 of the track structure. 'Ihese rollers are carried by the ear portions 430a which support` the shafts 43|a. Portions 43001. are integral with and form extensions on the ends of the portion 426.

Reference will be had to Fig. 1 and from the same it will be understood that the main frame structure shown in Fig. 17 is substantially I- shaped, including portions 426 at .each end of the transverse portion 425, and that in superposed relation to each portion 426 there is provided a portion 426. The portion 425 supports the handle 421, indicated by dotted lines in Fig. 17, because the section is taken between the handle and the remote rail 423.

'I'he upper portion 426 is adjustably secured to the lower portion 426 and master carriage portion by means of a pair of threaded bolts 400. These have threaded engagement with the member 426 through the threaded openings 40|. The bolts therefor extend upwardly above the portion 426. The bolt immediately above portion 426 mounts the adjusting nut 402 and the bolt extends through the opening 403 in portion 426. A nut 404 bears on the portion 426 and rigidly i clamps portion 426 upon the bolt structure carried in turn by the portion 426. Each side of the carriage structure is similarly formed.

The aforesaid adjustable connection facilitates the proper positioning and adjustment of the various rollers with respect to the track structure and thus eliminates the necessity for accurate machining or fitting which is necessary in connection` with the integral form of the invention shown more particularly in the left hand portion of Fig. 1 and in Figs. 4 and 5.

Reference will now be had to Fig. 18 wherein there is illustrated a perforating score knife for forming a cut-score line. In Fig. 18 numerals of the 400 series indicate like or equivalent parts designated by the primary numerals used in Figs. 11, 12 and 14. In brief this form of the invention includes the pivot forming opening 418, the body portion 411, the cam engageable portion 484, the handle pin engageable portion 486 and the socket structure represented by the body portion 480 bifurcated to form a groove or recess 488. A suitable pivot structure 490 extends from one wing or arm to the other and forms a pivot or axle upon which is mounted the wheel 483, the latter being included between said parallel wings.

The peripheral surface of the wheel indicated by the numeral 48|a is provided with a coplaner series of arcuately spaced cutting projections 48|. The teeth 48| are not only spaced apart in peripheral relation but are spaced from the side faces of the wheel 483.

In Fig. 19 there is illustrated a modified form of the foregoing which is a rotary type of creasing structure which functions in a manner somewhat similar to the knife illustrated in Fig. 20 but forms the type of conformation in the board operated uponl as does the creasing knife shown in Figs. 9 to 11, inclusive. Numerals of the 500 series herein indicate parts similar to those illustrated in` Fig. 18 and indicated by numerals of 400 series.` Thus, the body portion` 511 is provided with an opening 518 constituting the pivot bearing for the knife and the body portion is provided with the cam engageable abutment 584. It is also provided with the abutting portion 519 engaged by the projected member associated with the handleof the carriage. 'Ihe opposite end 580 of the body portion 511 is bifurcated as indicated at 588 and a screw 590 extends from one bifurcation to the other and forms an axle upon which is mounted a creasing wheel 583 having the median groove 58| therein and the Ytwo groove separated peripheral portions 58|a.

Herein there is provided a metal additiony member indicated by the numeral 582. It is angular in shape and the main portion thereof has an end 582C which abuts the end of the socket 588. The screw 599 extends through an opening in said member. The opposite end of the member 582 includes two projecting portions 5820. and 58217. 582a is the starting designator and 562D is the stopping designator, and these correspond to the linear starting and stopping indications 82a and 82h shown in Fig. 9.

It will be obvious that in order to secure the proper accommodation with the form of the invention shown in Fig.. 18 that the width of the cutting teeth and/or the length thereof and/or the spacing therebetween, may be that desired. In other words, a series of wheels may be provided with different widths et cetera, 'and each be interchangeable receivable by the holder structure. In a like manner, with respect to the form of the invention shown in Fig. 19, the creasing wheel may be similarly modified as to the depth of the slot and width of slot, and an entire series of said Wheels may be provided and interchangeably received by the socketed body portion of the knife structure.

It is also within the scope of this invention that the single handle structure of socketed type in terchangeably receives the cut-scoring wheel or the creasing wheel, although in the present instance an example of each is illustrated herein in Figs. 18 and 19, respectively.

In Figs. 20 and 21, there is illustrated a modied form of the carriage structure. In this respect these figures illustrate a form of the invention more clearly like that shown in Fig. 19 than that shown in Fig. 5, although for a complete understanding of the invention, reference must be had to Fig. 5 as well.

In Figs. 20 and 21 numerals of the 600 series indicate parts similar to those illustrated in Fig. 19 and indicated by numerals of the 400 series. This form of the invention essentially differs from that illustrated in Fig. 19 in that in place of the stop nut 402 being employed-see Fig. 19 the same is omitted and instead of portion 426 and 426 being rigidly connected together in spaced relation as are the parts 262 and 262 in Figs. 20 and 21, the same are yieldingly connected together in spaced relation. This is attained by omitting the locking nut 402 and interposing between the ornamental nut 604 and the body portion 626', the yielding compression spring 602.

The modified form of carriage shown in Figs. 20 and 21 further differs from that shown in Fig. 1'1 in that the horizontally mounted wheels 629 instead of being directly carried by the memberA `a bolt 62| having the head portion 622 is threaded into said aperture and extends through an aperture 624 in the tongue portion 626e. Interposed between the head 622 and the tongue portion 626e and concentric with the portion 62| is the compression spring 623. By means of this connection the carriage structure is arranged so that all wheels 629 engage the inside and confronting faces of the ytracks lso that lateral play between the tracks Vand the carriage is substantially eliminated.VV The adjustment previously described as of yielding character between the portions 626' and the two portions 626 Vof a modiedform of carriage as illustratedin Figs. 20 and 21 also prevents vertical chattering in the movement of the carriage structure upon the rails.

While the invention has beenillustrated and described in great detail inthe drawings and foregoing description, the same is to be considered as illustrative and not restrictive in character.
