BOX-MACHINE.
SPECIFICATION forming part of Letters Patent No. 536,021, dated. March 19, 1895. Application filed June 28, 1894. SerialNo. 515,988. (No model.) Patented in Germany August 27, 1892, No. 70,794.
To all whom, it may concern:
Be it known that I, MAX ESCI-IENBECK, a citizen of the United States, residing at Jersey City, Hudson county, New Jersey, have invented certain new and useful Improvements in Box-Machines, (patented in Germany August 27, 1892, No. 70,794;) and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
My invention relates to improvements in box-making machines, and particularly to an end-folding device to be used in connection with a machine for manufacturing paper boxes, in which the ends of the longitudinal side-pieces are bent inward before'the cross side-pieces are bent up.
The object of my invention is to produce an end-folding device which will be operated by the plunger automatically, and which cannot tear the paper at the corners of the box.
With this object in View, myinvention consists in a recessed female die having a finger pivoted at each corner in one of the recesses, the fingers being operated in pairs, by a Wedgedevice secured to the plunger, whereby the fingers are swung on their pivotal points in such a manner that those ends of the fingers which contact with the ends of the box to be folded are swung inward, turning on their pivotal points, and describing an are similar to that described by the infolded ends. By this construction, the ends of the longitudinal side-pieces are in contact with the fingers over the full extent of their outerv surfaces, and hence are not liable to be torn or damaged, as is the case when theend-folding device acts in a plane at right angles to the length of the longitudinal side-pieces.
The invention will first be described in connection with the accompanying drawings and then particularly pointed out in the claims.
In the drawings-Figure 1 is an end elevation of an end-folding device embodying my invention. Fig. 2 is a side elevation of the same. Fig. 3 is a plan, partly in section, of the same. Fig. 4 is a plan view of the boxblank as used on a machine provided with Fig. 5 is a detail sectional the female die, as shown at a At the corners of the female die are located a series of folding devices or fingers, B, each pivoted at b, in a recess in the female die, A, and having a short arm, I), and a long arm, 19 the latter being arranged at an angle to the short arm, as will be seen in the drawings.
0 is the male die, of a shape and size corresponding to the female die and secured to the end of a plunger, 0, which may be reciprocated toward and from the female die, by any suitable mechanism, not shown.
To the male die is attached a folder-operating device, consisting, in this case, of a pair of plates,D, secured to the male die, by bolts, d, each plate having its lower end wedgeshaped, as shown, and arranged to enter between the long arms of its respective folding fingers. By this arrangement, the descent of the plunger will cause the wedge-shaped portions of the plates, D, to crowd the long arms of each pair of the folding fingers apart, and thus swing the short arms inward, thereby folding in the end portions of the longitudinal side-pieces. The folding devices are returned to their normal positions bysprings,E,which connect the ends of the long arms of the fingers, as will be understood from the drawings.
The operation of my device is as follows: The box-blank, which is shown in Fig. 4, is placed on the female die either by hand or by any suitable feeding device. The plunger, being reciprocated in the usual manner, is forced downward, thus pressing the box-blank between the side walls of the female die, thereby bending the longitudinal side-pieces upward. As soon as this has been done, the
Wedge-shaped lower ends of the plates, D,
enter between the long arms of the folding fingers and thus crowd the said long arms of each pair away from each other, which causes the short arms of said folding fingers to swing inward, and thereby bend the ends of the longitudinal side-pieces toward each other. The continued descent of the plunger forces the box-blank farther into the (lie, and frees the inward-bent end'pieces from the folding fingers, at the same time causing the cross side-pieces of the box-blank to be bent into place against the inward-bent ends of the longitudinal side-pieces, where they are secured by adhesive material applied in any suitable way. The completed box may then be forced on through the female die, or, if preferred, may be allowed to cling to the plunger and withdrawn with it, being removed from the plunger when. above the female die, by any suitable stripper device. As the plunger is retracted, the wedge-shaped ends of the plates are withdrawn from between the long arms of the folding fingers, and the latter are returned to their normal positions by their respective springs.
Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-
1. In a box-making machine, the combination, with a slotted female die, of folding fingers pivoted in the slots and provided with long arms extending outside the die, a plunger, and a plate connected to the plunger and arranged to engage the long arms of the folding fingers, substantially as set forth.
2. In a box-making machine, the combination, with a female die, of a pair of folding fingers, each having a long arm and a short arm, the said arms being arranged at an angle to each other, a plunger, and a plate secured to the plunger, and provided with bevel corners arranged to engage the long arms of the folding fingers, substantially as set forth.
3. In a box-making machine, the combination, with a female die, and a plunger, of a pair of folding fingers pivoted to the female die so as to swing in a plane at right angles to the length of the plunger, and each provided with a long and a short arm, a plate connected to the plunger and arranged to force the long arms away from each other, and spring devices contacting with the said fingers, whereby the fingers are restored to their normal position, substantially as set forth.
In testimony whereof I aflix my signature in presence of two witnesses.
MAX ESCHENBECK.
