IMPROVEMENT IN MACHINERY FOR MAKING. PAPER BOXES,

The Schedule referred to in these Lett Patent and making part of the same.

10 all whom it may concern:

'Beit known that I, C. O. Gnosmgof New Haven, in the county of New Haven and State of Connecticut, have invented a new Machine for Making Paper Boxes; and I do hereby declare the following, when taken in connection with the accompanying drawings and the letters of reference marked thereon, to be a full, clear, and exact description of the same, and which said drawings constitute part of this speiziticatiom'and represent in-- Figure 1,- atop view;

Figure 2, an end view;

Figure 3, a side view;

Figures 4, a partial sectional view;

Figures-2, 5, 6, and 7, detached views to illustrate the operationof the machine; and in Figures 8, 9,10, 11, and 12',constru ction of the box as produced by the machine.

This invention relates to an improvement in the construction of a machine for making paper boxes,

. especially adapted to the box invented by me, and for which I have filed anapplication for Letters Patent of the United States, the object being to form, automatically, a box from paper or similar material, which, when. folded, is secured together during the process of folding, so as to dispense with the use of paste.

To enable others skilled in the art to construct and use my invention, I will fully describe the same as illustrated in the accompanying drawings.

I will first describe the box which it is designed to produce by this machine.

From a sheet of paper or board, I cut into the form seen in fig. 10, the broken lines indicating where the paper is who turned to fonn the angles, and where the folds are to be made. The angles 1, 1, 1, 1 are cut away as a matter of convenience, and not of necessity, so that the portion 2 will be not more in length than one-half the width of the box. The paper is slitted on the lines 3, 3, 3. Then the sides 4 4, with their connected parts 2 2, are turned up, and the parts 2 2 turned inward, to form a right angle. Then the parts 5 6 are turned up at each end, so that' the part 6 rests against the parts 2 2. Then the part 5 is turned down over the parts 2 2 into the box, as seen in figs. 1 and 2, it being of sufilcient depth to extend to the bottom of the box. Then an indentation, 7, is made in the bottom at the end of part 5, as seen in figs. 1 and 2, which holds the two parts 5 firmly in place, and securely binds the box together.

Boxes as heretofore constructed and secured together by paste or glue necessarily gather more or less moisture, which, particularly for matches, renders such boxes objectionable. This objection is overcome by my box.

I will now proceed to describe the machine for producingtbis box.

A is the bed-plate of, the machine, upon which, in proper bearings, B, rests the driving-shaft C, from which tbe'several parts of the machine are operated.

In a standard, I), a slide, 1), is arranged, operated by a cam, 13, through the lever D.

The paper or sheet from which the box is to be formed is passed tlll'ough anopening, a, in the stand- -ard I), the lower surface of the said opening and the under surface of the slide D being provided with a means for creasing the paper on the lines where the angles or foldsai'c to be made, and also with dies, 7, shown in solid black, fig. 1, for cutting away the necessary waste paper, as'and .for the purpose before described.

The slide, with its dies, operates upon the end of the sheet, as in fig. 8, cutting away the part 1 1, which forms one-half of two boxes. The sheet, after this operation, is fed along until the proper distance for again cutting and creasing the paper.

When the second operation is performed, to cut and crease the paper, as in fig. '9,'outtcrs (1, attached to the slide D, (see figs. 1 and 2,) cut the slits 3, (see fig. 9,) while, at the same time, a shear, e, upon a lever, E, operated by a cam,'E, cuts oh the paper a1 the center of the space 1 1, as denoted by the blue line, fig. 8, leaving the end of the sheet in the forn seen in fig. 9. From this point the paper is auto matically fed, by a revolving feed upon a, shaft, F, tr which an intermittent movement is given by a cam B, through a lever, F, and pawl F.

When the paper has been cut as in fig. 9, it is fe( along and operated upon as before, the shear 0 cutting ofl,.at the blue line, fig. 9, the blank, as seen in fig 10, which is in proper form for folding-and at the tim the shear separates the blank from the sheet, the blaul has passed beneath the slide I in the standard 1, tin said slide operated by the cam P through the lever I The said slide 1, descending upon the paper, presse it down between the two side dies J, (see fig. 2.) 1 corresponding follower, L, operated by a cam, L through a lever, L, beneath the machine, grasps th paper between the slide I and followerL in its desceu between the dies J J. This turns up the two sides 4 and the parts 2 2 connected thereto.

When the sides have thus been turned 'up, th transverse slides PP, to which the folders P are a tached, (see fig. 5,) are forced inward by the action l the cam 1, through the lever-P and its connectioi 'P, which turns the parts Zinward. Then the slii I again descends, carrying the blank down betwee =thc two end dies N N, (see fig. 4,) which turn up tl two ends 5 (I, passing down until the top of the b( comes flush with the top of the dies N. Then tl central portion I" of the slide, which is operated by: independent cam, I, through a lever, 1 remains st i tionarydowu, as seen in fig. 6,-while the other porti The box, after being thus folded, is pressed further down, until, at each end, or upon each edge of the slide L, a punch, L, (see fig. 5, and in broken lines, fig. 7 presses up into the bottom of the box, so as to indent, as at 7 7, which completes the box; and, when the slide around'which the box is folded is withdrawn,

the cam S, through a lever, S and a slide, S, (see fig. 2,) throws the box from the top of the slide L. A second box follows in like manner, and so continues making and completing the boxes.

The machine maybe adjusted for boxes of different sizes in similar manner as other automatic machines, as it may also for boxes of different forms; and covers for the boxes are produced in the same manner.
