MACHINE FOR CUTTING BOX-PATTERNS.
SPECIFICATION forming part Of Letters Patent N0. 272,354, dated February 13, 1853. Application filed' February 16,1882. (No model.)
To all whom it may concern: Be it known that I, JAMES M. TrTUs,.of the city, county, and State of New York, a" citizen of the United States, residing at Petersburg,
in the county of Din Widdie and State of Virginia, have invented certain new and useful Improvements in Machines for OuttiugBox- Patterns; and I do hereby declare the following mm a full, clear, and exact description of the inventiou,such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.
My invention relates to machines for cutting patterns from continuous sheets of veneer or analogous material, as hereinafter fully described, and specifically pointed out in the claims. In the accompanying seven sheets of drawings, Figure 1 is an end elevation ofa machine for scoriu g a sheet of veneer and cutting therefrom a pattern, from which a round-cornered box or dish is made, showing the manner of gearing the rolls. Figs. 2 and '3 show the same infront and rear elevation, respectively.
Fig. 4 is a transverse section of the machine, taken on line a: 00 ot'Fig. 2. view of the same. Figs. 6 and 7 show respectively diagrams of the periphery of a scoring and pattern-cutting roll for making round-cornered boxes or dishes from veneer. Figs. 8 and 9 are like views of the periphery of a scorin g and pattern-cutting roll for making squarecornered boxes. Fig. 10 is a longitudinal section of the pattern-cutting roll shown in Figs. 3 and 5. Fig. 11 is a like view of said roll, showing a modified arrangement of ejecting devices. Fig. 12 is 'an under side view of the pattern from which round-cornered boxes or dishes are made, and Fig. 18 shows in perspective a round-cornered box complete.
Like letters of reference are employed to indicate like parts wherever such may occur in the above figures of drawings.
In carrying out my invention, and in the construct-ion of square-cornered boxes, I first form in acontinuous sheet of veneer two continuous scores, composed of the parallel straight scores Fig. 5 is a top plan under a cutting-roll. that will cut a series of 7 patterns from the scored sheet and automatically remove the patterns as fast as they are cut from the cutting-cylinder. v
When square-cornered boxes are to be made, the sheet, scored asfirst above described,-is out into patterns by a cutting-roll, the knives or cutters M of which are arranged as shown in Fig. 9. In constructing round-cornered boxes from a sheet of veneer said sheetis first scored as above described, in successive patterns, each having two straight scores, 1, for the end flaps and a series of scores, 2, diverging from a point, 3, of the straight scores, to form the corners 4.. I next cut from the soscored sheet of veneer the patterns P, having end flaps, p, and rounded and radially-scored corner flaps a, as shown in Fig. 12. The end flaps,p, are then bent on the line of the straight score 1. The corner fiaps,p, are then bent on the lines of the radial scores 2, end flaps,p, and form the round corners, and said corner flaps are finally attached to the end flaps in any suitable manner, as shown in Fig. 13. In a practically similar manner I make the square-cornered boxes or dishes, cutting the blanks ot' the form shown in Fig.9, the knives M forming the edges of each pattern from a sheet of material scored, as above set forth, by the knives N of the scoring-roll.
The manipulation of the patterns when out by the pattern-cutting roll, Fig. 9, on which the scores are shownin dotted lines, will be readily understood, and needs no further explanation, especially as my invention relates more particularly to the construction of round-cornered boxes, the other forms being simply referred to as an illustration oftheinterchaugeable pattern and scoring rolls in the same machine, as
to' overlap the hereinafter more fully described, as aconvenience for cutting patterns either for round or square cornered boxes.
The scoring of the continuous sheet of veneer and the cutting of the finished patterns l from-said sheet may be effected in separate machines.
To save time and labor and the difficulty of causing the scored sheets to properly register with the pattern-cutters,l feed the scored sheet directly as it leaves the scoring-roll to the pattern-cutting roll. To avoid the patternssevered from the sheets from sticking to the cutters, I apply ejeetors to automatically eject the pattern from the cutters as they are cut from the sheet.
The machine embodying the mechanical elements of my invention is constructed as follows: Upon a suitable supporting-frame. F, are
mounted a bearing-roll, B, preferably of brass,
(though other suitable metal or wood may be employed,) a scoring-roll, S, and a pattern-cuttingroll,G,thelattertworolls beingmountedin adjustable bearings. 'llheadjustabilityof these rolls relatively to the bearing-roll is advantageous, as it enables the operator to adjust the depth of cutot the scoring and cutting roll. The relative arrangement of the three rolls is such that the bearing-roll B will serve as a hearing for both the scoring and cutting rolls, also as a feed and driving roll, the scoring and cutting rolls, as shown in Fig. 1, being geared with the bearing-roll and the shaft of said roll carrying the driving-pulley, and may also carry a loose pulley, for obvious purposes.
The scoring-roll S is provided around its periphery with the scoring-knives K, that form the straight end scores, 1, of the pattern, and with a series of knives or serrations, k, that produce the scores 2 of said pattern, which diverge from the scores 1, to adapt the corner fiaps,p, being bent, and take a rounded shape, as plainly shown in Figs. 3, 5, 6, 12, and 13. When patterns for boxes having square corners are to be cut the rolls (1S (shown in Figs. 2, 3, 5, 6, and 7) are removed, and rolls, like those shown in Figs. 8 and 9, are substituted, or any rolls having scoring andcutting knives for any other pattern. It will therefore be seen that boxes or dishes having round or square corners and made from different patterns may be made by changing the scoring and patterncutting rolls.
The pattern-cutting roll 0 has its knives L arranged to cut the pattern from which a box of a given shape is to be made. That shown in Figs.3, 4, 5, and 7 has its knives or cuttingedges L arranged to cut a pattern, I, Fig. 12, from which a round-cornered box is made, and those shown in Figs. 8 and 9 have their knives oreutters arranged to cut a pattern from which a square-cornered box is made.
The cutters are so arranged upon the periphery of the rolls as to form a continuous succession of patterns, and their diameter depends, therefore, on the size of the boxes or dishes to be manufactured, with which the cutters on the scoring-roll must always correspond, as will be readily understood.
The cutters or knives may be cast with the roll, and subsequently tooled or sharpened; or they may be attached to the rolls to score and cut the desired pattern. As the cutters or knives project some distance above the periphery of the roll 0, recesses 0, having the shape of the pattern, are formed, and as the cutting-edges of the cutters are beveled the pattern, when out by the passage of the cutter-roll over the sheet of veneer, is forced into these recesses c, and does not always fall out. Hence, when a pattern sticks, it has to be removed by hand, involving a great deal of labor and loss of time. To avoid this I apply ejectors to each of the recesses c, which may be composed of one or more spring-actuated follower-plates.
As shown in the drawings, the ejectors are composed of plates E, of any suitable material, preferably brass, actuated by coiled springs s, and held within the recesses c byheaded guidepins G. The head 9 of each pin lies within a countersink or enlargement, e, of the apertures 0, formed in the plate E, through which the pins pass. The guide-pins G are or may be screw-threaded at one end, and are screwed or otherwise attached to the cutting-roll O.
The coiled springs s are partially inclosed in recesses 0, formed in roll 0, as shown, and said coiled springs may be arranged in like re cesses around the guide-pins G, as shown in dotted lines, Fig. 11. Any other means for actuating the followers E may, however, be employed, and, instead of coiled springs, leatsprings .9 may be employed, as shown in Fig. 11, or any other form of spring may be used. The ends of these leaf-springs are forked or slotted, and straddle the guide-pins, said ends bearing against the under side of the opposite ends of the plates E, while the curved portion or back 8 of the springs rest on the periphery of the roll, no fastening being needed, as the guide-pins Gr hold the springs against lateral and longitudinal displacement. These leafsprings may be reversed, and their curved part or back 8 made to bear against the under side of the plates E, and their forked or slotted ends upon the periphery of the roll. Said springs may also be attached at the curved part or back 8 either to the underside of the plate E or to the periphery of the roll, as the case may be, and their ends left free to act either upon the periphery of the roll or the under side of said plate, according. as the spring is attached to the plate or roll. In their normal position the upper face of the platesE are flush or nearly flush with the cutting-edge of the cutters, and as the latter travel over the moving scored sheet of veneer to cut out the patterns the plates E are forced back into the recesses c by the severed pattern, and as soon as the cutters are out of contact with the bearing-roll B the plates are forced outward into their normal position by the spring or springs s, and the patterns are automatically ejected.
The arrangement of the cutters upon the periphery of the roll 0, as above described, is such that they form a continuous'series of pattern-cutting devices, each cutting out a pattern, the longitudinal cutters L forming the lateral edges of the patterns, thus severing each pattern completely from the sheet of veneer.
From the description of the construction of the machine its operation may be described in a few words, and will be readily understood by those acquainted with this-branch of the arts.
'lhebearingroll B being rotated through the medium ofits belt-pulley B from any suitable prime motor orby means of a crank and handpower, the other rolls are rotated, a sheet of veneer is fed between the bearing-roll B and the scoring-roll S, that forms the scores of the patterns, and the scored sheet passes from the latter roll directly under the cutting-roll O, that cuts out the patterns from the scored sheet, which, ilS-fzlSl] as cut, are automatically ejected from the cutting devices by the followers or ejectors E, and from which patterns the boxes are then made, as hereinbefore described.
The machine as constructed may be employed for cutting patterns or blanks from pasteboard, card-bo.ard,'or analogous material with equally good'results. 7
Having now described my invention, what I claim, and desire to secure by Letters Patent, 1S
