Original application filed March 23, 1914, Serial No. 826,637. Divided and this application filed July 13,

To all whom it may concern: I

Be it known that we, PAUL H. GRIMM and FRANK L. Coons, both citizens of the United States, residing, respectively, in Glen Cove, in the county of Nassau and State of New York, and borough of Brooklyn, county of Kings, city and State of New York, have invented certain new and useful Improvements in Package-Forming Machines, of which the following is a specification.

This invention relates to package-forming machines and has for an object to provide mechanism for incorporating in a container or package when the same is 1n process of manufacture, a sheet for adding to the security afforded by the container. This is preferably a sheet impervious to moisture, and may be of some suitably prepared paper, thus tending to preserve from deterioration the material which is afterward placed in the package. The addedsheet may be applied in the form of a lining if desired.

An object of the invention is to securely hold the sheet of impervious material in position upon the matrix during movements preliminary to the folding or wrapping operations.

The present application is a division of our copending application Serial No. 826,637, filed March 23, 1914 for packageforming machines.

In the drawings accompanying this application a practicable embodiment of the invention is illustrated in which,-

Figure l is a side elevation of a portion of a package forming machine certain of the parts being broken away to illustrate the relation of the parts lying beyond. Fig. 2 is a plan view of the wrapping and folding mechanism. Fig. 3 is a vertical section taken on the plane at about the line 33 ofFig. 2; and Fig. 4 is a vertical section taken on a plane at about the line 4-4 of Fig. 2.

That portion of a package forming machine or packaging machine which supplies the paper wrappers to the folding or forming devices, is illustrated herein. There is shown at A a stack of wrappers in position to be lifted and transferred to the folding device. This stack is shown upon a suitable Serial No. 850,675.

stack support or holder A vanced automatically in some suitable manwhich is adner, in the present instance a screw A 'being provided for this purpose; such feeding however being no part of the present improvement it is not described in detail.

The object of a portion of the mechanism illustrated is to feed tervals sheets a from forward at regular inthe stack A and to apply to or impose upon the uppermost sheet of the stack an interlining sheet 6. sheet Z2 is fed forward over the topmost sheet a of the stack The into such a position that the lifting and forwarding device will en gage both sheets simultaneously and lift them and transfer them. machine above referred to In the Smyser the uppermost sheet of the stack is engaged by pasting mechanism,

transferring,

the paste being utilized in the and after the sheet has been transferred to the folding device such paste is utilized f or the purpose of holding the wrapper in its folded position. In the present mechanism the such a position relatively added sheet is placed in to the position of the uppermost sheet in the stack and to the working point of the pasting and transferring mechanism, that the imposed sheet shares the paste with the sheet of the stack.

The two sheets are moved simultaneously and held together and are plied to the folding device.

There are ferring devi volve a horizontal reciprocate taken, from these pasting step by step in steps an arm 0, which arms are fast upon a plate 0' fast upon is mounted in suitable hearings in the framework of the ward the pl with ates C position by yielding means.

In the mechanism illustrated the point of delivery of the sheets from the pasting and transferring mechanism is the matrix H disposed substantially diametrically opposite the position of the stack holder A.

The lining paper is illustrated of less width than are the sheets a, and is fed over the stack so that its forward edge comes to rest prior to reaching the forward edge of the uppermost sheet upon the stack, so that there is exposed a margin a on the upper surface of the uppermost sheet of the stack at three edges of the sheet I). The pasting feet 0 are of such area that they engage this exposed margin and the edge of the sheet 7) adjacent thereto (see wavy lines in Fig. 2). When such feet are covered with paste and are depressed upon the superposed sheets a and b, the paste which otherwise would be applied to the surface of sheet a is shared by it with the sheet I), and upon the rising of the pasting device the two sheets are raised and transferred together. Feeding rolls are provided for feeding the paper stop between the shear blades Z2 which rolls are driven by a sprocket wheel 9 and chain 9. The paper is guided over the stack of sheets A into a position to be severed by the shears. The shear blade 72 is shown provided with an upstanding end b located in the path of movement of shear actuating devices 6 carried by the plate 0 upon the descent of the shaft C.

Each of the pasting and transferring devices stops in turn over the matrix H, the matrix and associated parts here illustrated being substantially those illustrated in the Smyser patent. Upon the downward movement of the transferring devices the interposed sheets a b are placed upon the upper surface of the matrix, whereupon the stripper I descends and holds the sheet or sheets in position during the upward movement of the transferring device. The stripper is illustrated in Fig. 11. After the stripper and the transferring device have been sufficiently advanced in their upward' movement, the matrix H is advanced toward the formers J J, that is, it is moved in the direction of the arrow in Fig. 2. In the use'of some papers in this mechanism, particularlywaxed or impervious papers, difliculty has been experienced in keeping the sheet of paper in position upon the matrix, and also in keeping it" inits proper position 11 on an associated sheet. For instance w ien the sheet I) is an impervious or waxed sheet, and the sheet a is of some other paper having no afiinity therefor, there is a tendency for the slippery waxed paper to slip i during the subsequent movements of the matrix, whi'ch'niovements consist in the The operation of the matrix being shifted from its horizontal position to the dotted line position shown in Figs. 2 and 4. When paper is drawn from a roll and drawn over surfaces in the manner described for the lining sheets,the paper becomes charged with a certain amount of static electricity which causes it to curl or buckle. For preventing the movement of the waxed paper and for the purpose'of preventing the movement of one sheetrelatively to the other, when more than one sheet is employed, a clamping device is illustrated, designated in a general way by the reference character K. A rock shaft 10' is shown carried at one edge of the matrix H. Upon this rock shaft are mounted clamping fingers is k tails k Suitable springs 70 are provided for holding the clamping fingers normally in their clamping position. In operation, the clamps are opened when the matrix is in position to receive the sheets. are then closed upon the sheets to hold them in position at the commencement of the movement of the matrix, and are in operative position during the tilting of the matrix. released just prior to the time the sheet will be delivered from the matrix to the former. Lugs k are provided at the edgeof the matrix, which is the forward and downward edge according to the various positionsof the matrix. A post k is shown secured to a suitable portion of the frame of the machine in such position that the tail 70 will be engaged by it and both clamping fingers H raised from the matrix upon this assuming its rearmost horizontal position. The front corner of the post is shown rounded at k for acting as a cam to rock the shaft is, and

provided respectively with The clamps The clamps are also automatically also to prevent too suddena movement of e the parts responsive to the springs when released from the action of such post. A slight forward movement of the matrix in thedirection of the arrow in Fig. 2 releases the clamping fingers, sheets. An engaging device is? is'provided for the tail k and is located in such a position upon the framework of the machine that such tail will be engaged and the shaft which then engage the p k rocked in time to release the clamping fingers from. the paper as this is drawn around the former. a

machinelis substantially as follows The pasting and trans-- ferring devices illustrated operate substan tially in the mannerset forth in the Smyser patent'above referred to and their operation will not, in, this part of the description, he

specifically mentioned except in'connection with the explanation of the associated'parts,

vance. At "each descent the paste covered except to state that at time intervals the feet will engage the uppermost sheet of the stack, apply paste thereto and utilize such paste in raising and forwarding the uppermost sheet of the stack. After a sheet a has been raised the present mechanism Will supply beneath it one of the extra lining sheets as a rider for the uppermost sheet of the stack by forwarding the lining sheet to position. The mechanism for forwarding and severing the rider or lining sheet is timed in such relation to the actuation of the pasting and forwarding mechanism that such rider sheet will be in position for sharing with the uppermost sheet of the stack the engagement of the lifting and forwarding mechanism.

What we claim is 1. In package forming mechanism, the combination with wrapping means embodying a matrix and a former associated therewith, of means for transferring sheets of paper to such matrix, means for moving the matrix from its receiving position to the former, clamps for holding the sheets upon the matrix, means for normally closing the clamps, and clamp releasing means located at the receiving and delivering positions of the matrix.

2. In package forming mechanism, the combination With sheet supporting means,

Copies of this patent may be obtained for five cents each, by addressing the of mechanism for pasting and transferring the sheet from such supporting means, mechanism for imposing a sheet upon said sheet in position to share with the same the paste from the pasting mechanism, a matrix for receiving the superimposed sheets, and means upon the matrix for holding the sheets thereon in the relative positions they occupy at the time of their engagement by the pasting and transferring mechanism.

3. In package forming mechanism, the combination with a sheet supporting device, means adapted for laying a liner sheet upon each such sheet, a combined pasteland transferrer adapted for pasting and transferring said superposed sheets, a matrix and a former for folding the said sheets, and means carried by the matrix for automatically engaging the sheets and holding them in their superposed positions occupied on the transferrer.
