SPECIFICATION forming part of Letters IPatent No. 408,712, dated August 13, 1889.

Application filed August 8, 1887. Serial No. 246,471. (Model.) Patented in Germany January 27, 1887, No. 40,405, and in England October 4:,1887,No.13,415

To CLZZ whom may concern: I

Be it known that I, HERMANN HENSCHEL, manufacturer, of Luckenwalde, in the Kingdom of Prussia and German Empire, haveinvented a new and useful Paper-Box-Nlaking Machine, of which the following is a specification, reference being had therein to the accompanyin g drawings.

This invention has been patented to me by British Letters Patent No. 13,415 of October 4, 1887, and German Patent No. 40,405, of J anuary 27, 1887.

The object of my invention is to provide mechanism which will form a box at one operation, said box having when inished a projecting bead around its lower, edge and plain cylindrical sides extending therefrom to the upper edge.

In the drawings, Figure l is a vertical section through the cutting-plunger, the male die carried therein being shown in side elevation, and the female die and support therefor, together with the blank, being also in seetion, all the parts being in normal position ready to begin the operation of forming the box. Fig. 2 shows the cutting-plunger and the male die moved downwardly a part of their entire stroke, the blank at this period of the operation having been out and pressed into cylindrical form. Fig. 3 shows the plunger and die at the limit of their downward movement, the box having now been forced through the female die, so that its lower edge Fig. 4 shows the next -step in the operation, the outtin g-plun ger and both the male and female dies having risen together, the relation between these parts being maintained as in Fig. 3, and this figure .also shows in section the block which causes the formation of the rib or bead on the box when the plunger and die descend. Fig. 5 shows this action of forming the bead by the descent of the female die and cutting-plunger. Figs. G and 7 are similar views representing the box as completed and being discharged.

The female die B B, having an opening b, of oval or .round shape, is held by long screws C C, projecting from the supports A A. The

- nuts D D on the upper end of the screws are somewhat above thefemale die, so as to al low the same to be moved to and fromthe bars AA, for a purpose hereinafter stated. This die B supports the blank, as at o, Fig. l, and directly above the opening in the die 4and over the blank the cutting-plunger E is about the male-die seat forms a cutter f, which severs the blank to the proper size when said edge is passing the upper edge of the femaledie opening. The male die projects below the cutting-edge, and of course is smaller in diameter than the opening in the female die, and thus when the said die with the cuttingplunger descends it forces the blank into the female die. and thus forms the cylindrical box, the sides of the same being between the sides of the said dies, as in Fig. 2, and at the same time this action takes place the cutting-plunger moves downwardly, and at the time the box has been formed, as in Fig. 2, the cutting-edge f has trimmed the surplus material from the edge of the blank, as at t, Fig.' 2. The male die E3 is movable to and from its seat in the cutting-plunger', and in the operation of the parts thus far described it occupies its lowest or outward position in relation thereto, bearing iirmly against the box-bottom; but at the proper time, as will hereinafter be pointed out, the said die moves back into its seat and leaves the bottom of the box free from support for the purpose of allowing the same to be upset to form the beadf After the box has been formed, as in Fig. 2, the male die and plunger continue their movement until thelower edge of the box has passed below the lower edge of the female die. This limit of movement is shown in Fig. 3, and after this has been reached these three parts-viz., the cutting-plunger,

male die, and female die-rise, but keep in the 9 same position relative to each other. A plate or anvil K is then moved into the opening in thev support A A to fill the same, and this is shown in Fig. Il. -The male die now moves back in its seat, leaving the bottom of IOO the box without interior support, and upon the downward movement of the cutter and female die, which new occurs, the bottom of the box is upset and a bead is formed between the anvil or plate K and the felnale die B, as shown in Fig. 5. After this the anvil K is removed and the continued movement of the plunger and die E3 effects the discharge of the box, as in Figs. 6 and 7, the latter of which shows the cuttin g-plun ger and male die raised again. The waste material i is then removed.

For the purpose of operating the male die to change its position in relation to the eutting-plunger, as above described, I employ a wedge E2, which works through an opening in the said plunger and the shank E of the male die.

I claim as my inventionl. In combination, the female die having a plain cylindrical opening extending through it to a point at or near its upper surface, the cutting-plunger E', having cutting-edges to pass into the opening in said die and cut a blank from the body of the material when it reaches said upper surface of the die, and a male die E3, carried by the plunger projecting at all times beyond the cutting-edgef, whereby the body of the material will first be pressed to form the box by the male die and then eut by -the edge f, substantially as described.

2. In combination, the female die B, the cutting-plunger E, the male die projecting normally beyond the cutting-edge of said plunger and arranged movably in said plunger, the Said female die being movable, means for controlling the male die, and an anvil or plate K, substantially as described.

3. In combination, the female die having an opening therethrough, means for cutting and forming the blank and for forcing the same partially through the female die, so that its lower edge will project therefrom, and the anvil or plate K, adapted in size to afford a bearing for the projecting edge of the box, the said female die and anvil K being movable, substantially as described.

In witness whereof I have hereunto set my hand in presence of two witnesses.

HERMANN HENSCHEL.
