APPARATUS FOR MAKING CARDBOARD BOXES.
Specification of Letters Patent.
Patented July 30, 1907.
Application filed September 7, 1905. Serial No. 277,382.
To all whom it may concern:
Be it known that LKARL Gosswnrtnn, manufacturer, a citizen of the Empire of Germany, residing at Schwarzenberg, Kingdom of-Saxony, Germany, have invented certain new and useful Improvements in and Relating to the Apparatus for Making Cardboard Boxes, of which the following is a specification7 reference being had therein to the accompanying drawing.
In my application under date of December 21st, 1903 Serial No. 186069 a process is described by means of which hollow bodies may be formed from disks of pasteboard or card-board by drawing, in which process the folding of the cardboard disks which necessarily takes place in the formation of the walls from a disk of cardboard which is itself flat, is rendered possible in accordance with definite rules, so that the creases of the folds are pressed in the cardboard disk by a preliminary pressing preceding the drawing operation. The manufacture of such hollow bodies from disks of cardboard is therefore composed of two operations, that is to say of the pressing of the folds preceding the drawing and the drawing operation itself. In order to simplify the process these two operations are effected in succession, so that, for instance, when it is desired to form an article of jug shape, the pressing ofthe folds is effected by-means of a matrix and die of the form of an annular disk which surround the actual drawing tool. In this arrangement it is necessary that the fold-pressing die should be raised from its matrix at the moment at which the drawing die proper becomes operative because if such were not the case, that is to say if the edge of the cardboard disk were still held between the foldpressing dies, the drawing die would merely act as a punch and would not draw the pasteboard into the drawing matrix but would'simply punch out material corresponding to its cross section. The two dies, that is to' say the foldpressing die and the drawing die must therefore act independently of each other in such a manner that in the first place the fold-pressing die descends, rises again and releases the pressed cardboard disk, the actual drawing of the cardboard disk taking place only after this. In order to carry out these two movements, hitherto, presses with two or three eccen trics have been employed of which that mounted in the middle actuated the drawing die, while those upon either side operated the fold-pressing dies.
The present invention has for its object an improvement in apparatus for carrying into practice the process described at the beginning of this specification, this improvement consisting in the fact that the reciprocating movements of the fold-pressing die and also the displacement of the drawing die are derived from a single descending part, say a single, eccentric.
A device in accordance with the invention is illustrated in the accompanying drawing in which Figure l is avertical section through the apparatus on apparatus with the omission of the parts designated z and r in Fig. l. Fig. l represents the position of the operative parts at the beginning of the operation, that is to say after the introduction of the disk of cardboard to be drawn into the apparatus, and the similar views in Figs. 3 and 4 illustrate two additional characteristic phases.
rlhe construction of the drawing and pressing mechanism is as follows:
Upon a plate a at the central portion of which the matrix m q required for drawing and for pressing the folds is arranged, a second plate b is guided upon a number oi' vertical spindles o, this plate being slotted centrally to permit of the passage of the drawing die r, and upon its under side it carries the annular fold-pressing die p.
The plate b is pressed upwards by means o f appropriately arranged springs d, the upward travel being limited by the heads arranged upon the upper end of the spindles c and constituting eyes g. In these eye bearings g are mounted bell crank pressure cams each being composed of two arms w, u their horizontal arms e acting upon. the plate b while upon the bearing faces on their vertical arms 'w a plate z mounted upon the drawing spindle r acts.
When the disk of cardboard 'Lt which it is desired to draw has been inserted in the apparatus, at the beginning of the downward stroke ol' the spindle r the plate z mounted upon the spindle r in sliding downwards upon the bearing faces of the arms 'w of the cams causes the rocking-of the cams t w and in this phase, which is intermediate between the positions represented in Figs. l and 3 the plate b carrying the fold-pressing die p is depressed against the action of the springs (l and the pressing of the folds is effected. l
In the Iphase of the displacement illustrated in Fig. 3 the edge of the plate z slides over the final lines of the bearing faces of the arms w, whereupon the springs d tending to press the plate b upwards again become operative and in the next phase of the stroke, which is intermediate between the positions shown in Figs. 3 and 4, they again raise the fold-pressing die p from the matrix m and thereby release the cardboard disk u. as is represented in the position shown .in Fig. 4, which the actual drawing of the cardboard diskbegins, as it is only at this phase that the drawing die r reaches the level of the disk u, that is to say, becomes operative. During the displacement of the drawing die r which now takes place the cardboard disk is drawn into the matrix q in the manner described in the application referred to above and the hollow body is formed. Upon the return of the drawing die r the fold-pressing die p l is again pressed against the matrix m, this movement is the line A-B of Fig. 2, and Fig. 2 is a plan view of the of no importance, however, as it is an idle movement, thatlistotsaythereisno material, between the operative parts.
Having 'now particularly described and ascertained the nature o1' my said invention and in what manner the same is to be performed, I declare that what I claim is:
1. Pressing or drawingdevice for hollow articles of cardboard, composedof a bottom plate with a central opening; and a lower folding die around said opening, of a movable top plate, and a central perforated upper folding'vdie,V
of a drawing die or plunger', corresponding,- in conguration to said central openings but less in thickness for the'lfwalls of the object to be drawn substantially as describedgf 2. lressing or drawing device for hollow articles of cardboard composed of a bottom plate with a central opening, and a lower folding die around said opening, of a movable spring-supported top plate, and a central perforated upper folding die, of a drawing` die or plungerl corresponding in configuration to said central openings but less in thickness for the Walls of the object to be drawn, of spindles o in the bottom plate adapted to guide the top plate and having heads with eyes g for cam levers, of bellcrank cam levers fulcrumed in said eyes and of a plate e' mounted on the plunger lr and adapted to press the dies together by moving said cam plates substantially as described and for the purpose set forth.v
In testimony whereof I hereunto aix my signature in presence of two Witnesses.
