Application filed May 12,

To all whom it may concern.

Be it known that I, JAMES F. CLEARY, a citizen of the United States, residing at Kansas City, in the county of Wyandotte and State of Kansas, have invented certain new and useful Improvements in- Box-Blanklowing to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertalns to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part ofthis specification.

"This invention relates to box blank scorlng machines and it contemplates the provision of means for increasing the capacity over that of known types of machines for accomplishing the same pur ose.

In the manufacture of ber boxes it is cus tomary to score the blanks along the lines to be creased or bent to provide sides and ends and where heavy fiber board or card board is employed it is customary to effect the scoring by embossing the fold lines through the medium of suitable dies. Prior to my invention, the general practice was to provide a roll with a groove or female die to co-operate with the complementary roll having a rib or male die, the dies running longitudinally-of the rolls and adapted to register once during each revolution of the respective rolls. Since the dies were only brought into registration once during each revolution of '.the rolls, there was considerable lost motion due to the fact that no scoring took place between the time that the dies moved out of ,contact until they caine into contact again;

therefore, the out-put of the machine was necessarily restricted.

Accordlng to my inventionI have provided means whereby the scoring may be continuous so that the dies are continuously operat-f ing upon the blank from the moment of introduction until the moment of discharge. This enables the machine to have a greater production and, on account of the increased out-put, the cost of scorlng each indivldual blank is materially reduced.

Broadly my invention includes dies linked together and traveling around rotating olements to score the blanks in the direction of travel of the blanks so that the operation may be continuous and so that the successive blanks may be fed up close to the preceding Specification of Letters Patent.

blanks and thereby contribute to. increased production. The dies are generally arranged in multiples to I have provide means whereby sets of dies may be adjusted sidewise so that the scoring may be any distance apart between two extremes.

In the preferred embodiment of my invention I provide a base frame consisting of the sides 1 and 2 which may be connected by suitable members to be referred to hereinafter. Superposed upon the base frame is a supplemental frame including the spaced double channel members 3 and 4 which extend transversely or across the machine and which are connected to end pieces 5 supported on the upper edges of the sides 1 and 2. The double channel members have their respective webs 6 and 7 in parallel spaced relatioii and their respective flanges provided with dove-tailed projections, as indicated at. 8 and 9 (Fig. II), the purpose of the dovetailed projections being to support laterally j (provide multiple scoring and ber-carrying wheels 13 and 13', 14 and 14', 15 and 15 and 16 and 16, the wheels or disks being connected together by spiders, as indicated at 17 in Fig. II and the peripheries of the spiders being provided with Wheel-re ceiving notches 18 which are en aged'b the roller bearings carried by the ie mem ers,

as Willbe explained hereinafter. On the forward part of the machine and supported in bearings 19 and 20 is a splined shaft 21 cartion rollers on the linked die members so that there can be no independent movement of the die members and disks.

- Below the disks and on opposite edges of the double channel member 4 are shafts 27 a and 28, the shaft 27 being supported in bearings 29 and 30 on the end members 1 and 2 and the shaft 28 is supported in bearings 31 also carried by the ends 1 and 2. The ends of the shafts 21 and 28 carry spur gears 33 and 34 which mesh one With the other so that the shafts must rotate inunison and thereby rotate all of the disks or wheels which they carry, and since the disks or wheels on each shaft'21 and 28 are splined to the shaft and since the gears 33 and 34 have a one-to-one ratio, a rotation of one shaft will impart a rotation to the other shaft at corresponding speed. The motion is imparted to the gear 33 through a gear 35 on the shaft 36, which carries a sprocket 37 adapted to be driven by a chain 38 from any suitable source of power, and the gear 33 meshes with a gear 39, which drives a gear 40 on a feed roller shaft 41 supported in a bearing block 42 carried by a bracket 43 supported by the forward end of the machine, and the gear 40 meshes with a gear 44 on a complementary feed roller 45 which is adapted to be pressed against the feed roller 41 by a' spring 46 in the usual manner.

The die members are illustrated in detail in Figs. V, VI and V II. For example, the

proper by any suitable fastening devices as, for example, screws 53. The die members proper may be the female or male but in Fig.

V I have shown the die member as a female die member provided with a groove 54 to receive a corresponding rib 55 on the male die member 47, it being understood that one set of die members is carried by the wheels on shafts 12 and 21 while the other set of die members is carried by the wheels on the shafts 27 and 28. When the pintles 57 are speed at which they travel so that there will be no relative movement between the blanks and the dies and, since the chains move longitudinally of the machine or in the direction oftravel of the blanks, the scoring may .be a continuous operation. For example,

the length of the scoring is limited only by the length of the blank; therefore, the blanks may be fed up close together and thereby eliminate the liability of lost motion or restricted out-put.

The feed roller 44 is shown as provided with cutters 60 which may co-operate with cutters 61 on the shaft 45 so that the sheets fed to the machine may be cut and trimmed I in their passage thereto. For example, the cutters in -Fig. III are arranged so that a sheet may be fed to the machine and severed in the center by the central cutters to separate two blanks and the end cutters will trim the edges of the'blank, it being apparent by reference to Fig, III that the illustrated machine is arranged for sc'oringtwo blanks at one operation, the scoring in the present machine being devoted to embossing the lines 63 and 64 of the blank 65 (see Fig. VIII).

The machine is adapted to score blanks of different sizes and to provide scoring of blanks of like sizes different distances apart and to this end I have provided means for laterally shifting the die chain-operating disks or wheels and the shifting mechanism is best illustrated in Figs. I, II, III, IV and IX. 'By reference to Fig. IX it will be observed that the shifting member may consist of a plate 66 having an outstanding finger or projection 67 at one end provided with a lateral extension 68 which ma engage between two parallel disks of a'chain operating wheel. In the present instance, the finger 67 is' shown as engaging between a pair of forward disks on the machine and a corresponding projecting finger 69 at the other end of the plate 68 is shown as engagingbetween a pair of disks on the discharge end of the machine, it being understood that there is a separate device for each set of disks consistingo-f a forward wheel and a rear wheel. Therefore, since ithere are eight wheels on the lower deck and 8 wheels on the upper deck and as each two wheels constitutes a set, there will be eight shifting devices or four shi' fting devices operated from the right hand end of the machine and four by a corresponding mechanism on the left hand side of the machine. The plates 66 are positioned 'with' respect to the channel members by dove-tailed jaws 70 which engage the dove-tailed projections 8 and 9 on the res ective members 3'and 4.-

and along which t ey are adapted to slide,

being actuated by the screw shafts 71 or 72 for the right hand side of the machine and 73 or 74 forthe left hand side of the machine, said screwshafts carrying beveled gears 75 and 76, and 77 and 78, the beveled gears 75 and 77 being operated by beveled gears 79and 80 on a shaft 81 and the beveled gears 76 and78 being operated by the beveled gears '82 and 83 on the shaft 84, a crank 85 being provided to operate either shaft by removing it from one and attaching it to the other. Therefore, when the shafts 81 or 84 are rotated, the shifters will be moved laterally of the machine and shift the sets of die operating wheels toward and away one from the other to increase or diminish the space between parallel lines of scoring, the lateral shifting not affecting the rotative action of the wheels on the forward end of the machine which are splined to their shafts 21' and 28. a By reference to Fig. IX it willbe observed that the plates 66 are provided with bosses or projections 81 which support the die link guides or bridge members 86 (see Figs. II and IV) and thereby prevent the linked dies for the upper deck from. sagging, as will be apparent by reference to Fig. IV.

In describing this invention I have referred in detail to a complete set of mecha nisin presumably on the right hand side of the machine and have shown a duplicate set of mechanism on the left hand side of the machine which will be readily recognizable by reference to Fig. III, but since the mechanism on the left hand side of the machine is a counterpart of that on the right hand side of the machine, it is deemed unnecessary to again specifically refer to the detail parts thereof, the manner of duplicating the mechanism being obvious by reference to the drawings, it being apparent that 2 will be'properly spaced by the superposed frame and the shafts with their bearing members but these may be additionally braced by the members 87---87.'

I By reference to Fig. X it will be observed that the horizontal beveled gears on the shifter adjusting shaft are held in mesh with the vertical gears on the vertical shafts by removable inverted U-shaped spacing collars There is a spacing collar for each horizontal shifter operating shaft and the collars are removable so that in the event that it is necessary to adjust any particular shifter to bring the linked dies in proper position, a collar may be removed and a particular shaft may be turned independent of the other shafts, so that while the top and bottom shifters of a set are ordinarily operated in unison, it is possible toindividually adjust any shifter by simply removing the collar and exerting longitudinal pressure on the horizontal shaft to throwrits gear out of mesh with the beveled gear which drives it.

Fromthe foregoing description, it will be apparent that the blanks may be fed from a table 88 to the feed rollers 41 and 15 where they may be acted upon by the cutters 60 and in the machine to be acted upon by the scoring dies in a continuous manner and discharged onto the receiving table 89 and that the blanks can be fed much more quickly than in any known type of machine because there is'no lost motion due to intermittent blanks, abaseframe, oppositely disposed channel members supported by the baseframe and spaced one from the other, the flanges of the channel members having heads on.the free edges thereof, belt shifters slid able on "the heads of the channel members, sprockets mounted in the frame, belts engaging the sprockets, die members carried by the belts, means on the shifters for engaging the sprockets to shift them laterally, and means for imparting lateral movement to said shifters.

In testimony whereof I aflix my signature.
