MAX ESOHENBECK, OF JERSEY CITY, NEW JERSEY, ASSIGNOR TO JULIUS MOHS, OF DRESDEN, GERMANY.
BOX-MAKING MACHINE.
SPECIFICATION forming part of Letters Patent No. 538,770, dated May 7, 1895. Application filed October 2, 1894:. Serial No. 524,706. (No model.) Patented in Germany August 2-7, 1892, No. 70,794.
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 crossside 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 will bend the paper gradually, so as not to tear the paper at the corners of the box.
With this object in view, my invention consists in the features, details of construction and combination of parts which will first be described in connection with the accompanying drawings and then particularly pointed out in the claims. I
In the drawings, Figure 1 is an end elevation, partly'in section, of a device embodying my invention, the folding devices being shown in their normal or inoperative position, the plunger being raised. Fig. 2 is a similar view with the following devices in their operative position and the plunger down. Fig. 3 is a plan view of the device. Fig. 4 is a side view of the same. Fig. 5 is a plan of a boxblank as used in a machine provided with my improvements.
Referring to the drawings, A is a female die, in this case adapted for the manufacture of rectangular boxes, and provided with side walls, a. The end walls, a, of the female die are not of the same height as the side walls, a, by which construction an opening, a is left at each end of the female die. At each corner of the female die is located a finger or bell-crank, B, pivoted at b, in a recess in the female die, each bell-crank having a folding arm, Z), and an outward-extending arm, b the latter being arranged at an angle to the folding arm, preferably at a right angle, as shown.
C 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 by any suitable mechanism, as shown.
To the male die is attached a .folder-operating device, consisting, in this case, of a pair of forked plates, D, secured to the male die by bolts, d, and provided with arms, d, which have theirinner corners beveled off, as shown. The outward-extending arms, b, are each provided with. contact pieces, b consisting, in this case, of studs or lugs, arranged to be engaged by the beveled corners of the arms, d. By this construction, the descent of the plunger will cause the beveled corners of the plates, D, to crowd the outward-extending arms toward the female die, and thereby swing the folding arms inward and toward the outer face of the female die, swinging in arcs on the pivotal points, b, whereby the end portions of thelongitudinal side pieces are folded inward.
The folding devices are returned to their normal positions, preferably by the weight of the folding arm, b, in machines where the plunger is vertical, in which construction the said folding arms are made heavier than the outward-extending arms; but the folding devices may be also returned to their normal positions by means of springs, E, bearing against the ends of the outward-extending arms, b and secured to the female die, as shown in Fig. 4.
The operation of my device is as follows: The box blank, which is shown in Fig. 5, is placed upon the female die either by hand or by any suitable feeding mechanism. The plunger, being reciprocated in the usual manner, is forced upon the box blank,thus pressing it between the side-walls of the female die,
.to swing inward and bend the ends of the longitudinal side-pieces toward each other. The
continued descent of the plunger forces the box blank farther into the female die and trees the inward-bent end-pieces from the folding arms, at the same time causing the cross sidepieces 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 manner. The completed box may then be forced on through the female die, or, if pretion, the folding of the ends of the longitudinal side-pieces commences at that part which is farthest in the female die, and extends from there outward, whereby it is possible to so construct the machine that the folding will commence as soon as the blank has just entered the female die and before the longitudinal side-pieces are completely bent to their proper position, the folding of the end pieces being thereby rendered nearly simultaneous with the forming of the said longitudinal sidepieces, whereby the time necessary to bend the blank is reduced and the capacity of the machine increased, while, at the same time, the shearing action of the folding device on the blank is reduced, for the reason that the folding arms movein an arc-shaped path,swinging on their pivots, b.
In my Patent No. 527,146, dated October 9, 1894, for machines for manufacturing boxes and plates, I have shown a folding device which also accomplishes the results above set out, but such folding device has one disadvantage when employed With a female die for the production of shallow boxes, namely, that the outer ends of the folding fingers project above the outer surface of the female die, if the latter be shallow, thereby interfering with the placing of the box blank over the die. By my present construction, this disadvantage is avoided, as will be plain to those skilled in the art.
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 female die, of folding devices pivoted to the die and provided with folding arms, and outward-extending arms at an angle to the folding arms, a plunger, and a plate attached to the plunger and arranged to engage the outward-extending arms of the folding devices, substantially as set forth.
2. In a box-making machine, the combina tion, with a slotted female die, of folding fingers pivoted in the slots and provided with folding arms and with outward-extending arms at an angle to the folding arms, a plunger, and a plate connected to the plunger and arranged to engage the outward-extending arms of the folding devices, substantially as set forth.
3. In a box-making machine, the combination, with a female die, of folding devices pivoted to the die, each folding device being provided with a folding arm and an outward-extending arm at an angle to the folding arm and having a contact device, a plunger, and a plate connected to the plunger and arranged to engage the contact devices, substantially as set forth.
4. In a box-making machine, the combination, with a female die, of folding devices pivoted to the die, each folding device being provided with a folding arm and an outwardextending arm at an angle to the folding arm, and having a contact device, a plunger, and a forked plate connected to the plunger and having its forks arranged to engage the contact device, substantially as set forth.
5. In a box-making machine, the combination, with a female die, of folding devices pivoted to the die, each folding device being provided with a folding arm and an outwardextending arm at an angle to the folding arm and having a contact stud, a plunger, and a forked plate connected to the plunger, the forks of the plate being beveled on their inner corners and arranged to engage the con tact studs on the outward-extending arms, substantially as set forth.
In testimony whereof I affix my signature in presence of two witnesses.
