PACKAGE-FORMING MACHIN.

Application led March 23, 1914.

T0 all fev/1.0m it may concern Be it known that we, PAUL H. GRIMM and FRANK L. Cooks, both citizens of the United States, residing, respectively, in Glen Cove, in the county of Nassau and State of New York, and borough of Brook lyn, county of Kings, city and State of New York, have invented certain new and useful Improvements in PackageForming Machines, of,V 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 in process of manufacture, a sheet for adding to the security afforded by the container. This is preferably a lining impervious to moisture, and may bev of some suitably prepared paper, thus tending to preserve from deterioration the material which is afterward placed in the package.

The illustrated embodiment of the invention is in one aspect in the nature of an improvement on the Smyser machines an illustration of an example of which is to be seen in U. S. Patent No. 505,857, issued October 3, 1893.

Although the parts for feeding the additional or interlining sheets are adapted to be supplied to existing machines, and when present may be used or not as occasion may demand, and may be removed entirely from the parts making up the simpler mechanism.

without disassembling the latter, yet the new parts and the old form a unitary organization cooperative in effecting new results, and producing a new product in which the new elements enable the old elements to perform new functions, thepresence of the new elements enabling the old elements to produce a new product.

In the drawings accompanying this specification a practicable embodiment of the invention is illustrated in -whicli,-

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 a portion of the device illustrated in Fig. 1, andis taken on a plane at about the line 2-2 in such figure.

Fig. 2 is an enlarged section taken on a plane at about the line 28- a of Fig. 2; Fig. 3 is a detail view partly in vertical section of the mechanismillustrated in Fig. l, showing the parts in a different position; Fig. 4 is a somewhat similar view showing the parts in a still different position; Fig. 5 1s a plan View of the mechanism shown at the left hand side of Fig. 1, the driving mechanism being broken away; Fig. 6 is a section taken on a plane at about the line 6 6 of Fig. 1 looking in the direction of the arrows; Fig. 7 is anenlarged section taken on a plane at about the line 7*7 of Fig. 'l looking in the directionof the arrows; and Fig. 8 is a detail plan View of the cam shaft and cams.

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 andtransferred to the folding device. This stack is shown upon a suitable stack support or holder A which is advanced automatically in some suitable manner, in the present instance a screw A2 being provided for this purpose; such feeding however being no part ofthe present improvement it is not described in detail;

The object of the mechanism illustrated is to feed forward at regular intervals sheets a from the stack A and to apply to or impose upon the uppermost sheet of the stack an interlining sheet 5. The sheet yb is fed forward. over the topmost sheet a of the stack into such a position that the lifting and forwarding device will engage both sheets simultaneously -and lift them and transfer them. In the Smyser machine above referred to the uppermost sheet of the stack is engaged by pasting mechanism, the paste being utilized in the transferring, and after the sheet has been transferred to the folding device such paste is Iutilized for the purpose of'holding the wrapper in its folded position. In the present mechanism the added sheet is placed in such a position relatively to the position of the uppermost sheet in the stack and to the working point of the pasting and transferring mechanism,

that the im o'sed sheet shares the paste with the sheet of the stack. The two sheets are moved simultaneously and held together and are so fed or supplied\to the folding device.

There are shown four pastinga'nd transferring devices C which are'caus'ed to revolve step by step in steps of90 degrees in a horizontal plane, and are also caused to reciprocate vertically, -between the `steps taken, from the horizontal plane. Each of these pasting devices is shown carried by an arm c, which arms are fast upon a plate c fast upon a vertical shaft C', which'shaft is mounted in suitable bearings in the framework of the machine, and is held in its upward position by yielding means. Each of the plates C is provided upon its underside with paste receiving feet o2 for engaging the pasted surface of paste disk c3, which `paste disk is caused to rotate and its surface be thereby supplied with paste from a reservoir c4. The stack holder A is disposed at a position below one of the between step positions of the plates C, and the paste disk c3 is disposed at another such position, so that these two portions of the device are disposed at angles of approximately 90 degrees about the shaft C. '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 carried by the roll B is illustrated of less width than are the sheets a (see Fig. 2) and the lining paper 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' margine on the upper surface of the uppermost sheet of the stack at three edges of the sheet 6. The pasting feet c2 are of such area that they engage this exposed margin and the edge of the sheet 6 adjacent thereto (see dotted lines in Fig. 2). When such feet are covered with paste and are depressed upon the superposed sheets a and 6, the paste which otherwise would be applied to the surface of' sheet a is shared by it with the sheet 6, and upon the rising of the pasting device the two sheets are raised and transferred together.

Suitable mechanism is provided for unwinding and advancing the paper from the roll B. In the present instance the sheet or stock of paper is pushed forward by rotating the roll and by means of suitable roller guides is again pushed forward over the stock and the sheet is there severed from the stock. The roll is shown mounted upon aI 6* pivoted to one end. 6's of a bell crank, the y other end 6 of which is operated by mecha nism presently to be described.

A certain amount of adjustable overthrow is provided for the pawl 63. It is shown longitudinallyumovable in the pitman 64 and 1s held in its adjusted position by means of a .suitable set-screw 67. By this means the amount of movement imparted to the roll by uniform oscillations of the bell-crank 6'5 68 may be adjustably varied as desired. An antifriction roll 68 is provided for holding the pawl 63 to its work. One great diiculty vexperienced in this class of mechanism is overcoming the inertia of the roll of paper B, and guarding against the momentum which it acquires when advancing the stock of paper step by step. Considerable leverage is aiforded by the present mechanism, and the paper is started forward and advanced without undue strain to the parts of the machine or to the paper itself, and the paper 1s accurately measured, and positively stopped at the predetermined position.

The stock of paper from the roll B is led to idler rolls 69, and to a pair of guiding and forwarding rolls 61 611 which, in the present illustration are positively driven. In the present illustration the lower roll is made of smooth brass and the upper roll is made of smooth rubber. A support 612 is provided for the paper in case the amount fed from the roll is in excess of the demand of the rolls 610 611. A guide 613 is provided in front of the rolls 61 611 for similar reasons. At the discharge side of such rolls a funnel-shaped guide 614 is provided. Suitable shears are provided for severing the stock adjacent the stack A. Such shears in the present illustration comprise a fixed blade 615 and a movable blade 616. A supporting plate 61T is provided at the stack side 0f the shears for supporting the rear edge of the sheet 6 after this has been severed from the stock. A coiled spring 618 is provided for normally holding the shear blades open. Irregularities frequently occur in the rolls of lining stock B, sometimes in the cores on which the rolls are wound, sometimes in the paper itself being thicker at one side than atvthe other; to assure the accurate feed, one of the rolls 69 in the drawings the upper of these rolls, is mounted in a shiftable box 69, engaged by adjusting screws 6"1 691 whereby 'such irregularities or inequalities may be rectified by adjusting the position of such roll.

The main driving shaft of the machine is shown at D, and is driven by a pulley d. This shaft is shown havingfixed upon it a worm d meshing with a worm-wheel d2 which is fast with a shaft d carrying a bevel gear d4 meshing with a bevel gear als which is fast on the cam shaft df. Upon the cam shaft d are mounted the driving cams of the machine. The cam wheel Z7 is provided with a M for aeaeiving das .antifrictiou roller in the end of a lever d, whach lever is connected by means of a linkd" with an arm c carried yby -a hub -c loose on the shaft C. The plate c is shown provided with four holes c1 for receiving a lug cnl on the under side of the arm c5 when the shaft l is in its elevated position. The throw of Ythe lever d is so adjusted and -the connections so proportioned that at each rotation of 'the `cam shaft the plates C are rotated through, an angle of 90 degrees. A cam wheel d10 is also mounted upon the cam shaft and is provided with a groove for receiving the antifriction roller -of a lever dn which is connected by means of a link d with a head member d 'carried by the upper end of the shaft C. The cam groove and .associated parts are so proportioned and timed that after the plates C have been stepped around 90 vdegrees in a horizontal. plane, the plates will be forced downward, bringing the paste feet c' of one pasting and transferring plate in engagement with the surface of the paste disk c3, and bringing the paste 4feet -of the preceding `plate in engagement with the superposed sheets a b at the top of the stack. The head d is provided with an opening in eachcorner, which openings register with guide pins d suitably carried by the machine frame and provided with conical ends for :the pur ose of justifying the position of the plate c at, the beginning of its descent and for'guiding it in a true line. The shear blade b1 is provided with an upstanding end b1 located in the path of movement of shear actuating devices b carried by the plate c" upon the descent of the shaft C.

There is shown mounted on the driving shaft D a worm `e meshing with a worm wheel e mounted upon a shaft c2, which shaft is shown provided with a bevel-gear e3 meshing with a bevel gear e'1 fixed upon a shaft e5, which shaft is the driving shaft for intermittently feeding the stock forward for supplying the interlining sheets b. The continuously rotating driver E for such portion of the mechanism is shown fast upon shaft e". This driver in connection with suitable engaging mechanism is timed for stepping the gear wheel e6 forward at suitable times to feed the interlining sheets over the uppermost sheet of the/stack at such times as the pasting andtransferring mechanism is out of the path of movement of the oncoming interlining sheet. This mechanism comprises au intermittent clutch. The gear wheel e is mounted free upon a iange e' (Fig. 7) which 'formsl a part of the bearing for the shaft cs and the driver E. This flange is carried by a plate e8 securely fastened to the framework of themachine. The driver IE is of disk `formation cut away and having la finger e9 for engaging, when dll @EGW fara@ the 10 @M- by lthe wheel ce. in the present illustration there are foar of these pins vset at angles of 90 degrees one to the other about the axis one of the pins to ride up this inclined face f and on :to the 'fiat portion of the track, which will then bring the outer end of thc pin into gpsition to be engaged by the finger e. The ger will then, move the wheel e forward until .the pin which it is engaging runs oi the end o the track-and is returned tov idle -position by means of lits spring.- This will then release the wheel e? from the engagement of the actuator E and permit such actuator vto move forward idly. -Just prior -to the pin which is .in engagement with the finger running off the track, -the pin behind it runs up on the inclined surface and on to the level surface of the track and is in position to engage the finger e9 upon its next rotation, that is, the finger e9 is in engagement with a pin through 90 degrees of its r0- tation and moves from engagement with a pin and idle during 270 degrees of its rotation. One portion of the plate forming the actuator E constitutes a cam e13 upon its edge. This portion of the plate is provided with a raised rib e for clearing the pins el and their pockets. The serrated face of the cam e13 actuates the pawl b3 through the roll f5, bell crank b5 b and pitman b4.

A brake F -is provided for the roll B, or its carrier, and engages a friction face f fast with the shaft which carries the roll material. This brake is actuated by means of the camface e. The depressions forming the serrations for actuating the pawl b3 are not sufficiently deep to' permit the brakes to become active. The brake is carried by la stem f2 and is pressed toward its work by means of a coiled spring f3. It is raised by means of the lever 7'* which carries a roll f5 running upon the cam facev els. The lever f is pivoted at f, and is connected to the brake stem y"2 by means of a link f2". Adjusting means is provided for the brake in the form of a nut ffl mounted upon the stem f.

It has been found, desirable to assist the forwardin rolls in advancing the stock from whic the lining sheets b are severed. To this end the roll B is unwound or rather it is rotated in such a direction that the material unwinds from it to approximately meet the demand of the forwarding .rolls by the pawl and ratchet mechanism above described. The forwarding rolls are supported in the present instance by means of a bracket 621. secured to the main frame. The rolls are provided respectively with intermeshingpinions 622 623. The rolls are rotected by means of housings 624 625; 624

1s shown secured directly to the bracket 6"1V and the housing 625 is shown secured to a plate 626 which is adjustably secured by means of set-screws to the bracket. Setscrews 6" 62s are provided for engaging the .plate 6L6 and the end of the housing 6"5 for forcing the rolls together.

As stated above the roll 61 is provided on its outside with a rubber face and the roll 611 is provided with a brass face. In the present gearing at each period of movement o f the sprocket wheel G the forwarding rolls will 'advance 5`l revolutions and accu- 'ratel}7 measure the lining sheet 6. The rolls 610 611- are shown driven in 'the following manner: One of the rolls, as for-instance the lower roll 611, has fast with it a sprocket wheel g (Fig. 6) over which runs a sprocket chain g1 running over the driving sprocket G, which sprocket has fast with it a pinion g2 meshing'with an idler g3 (Fig. l) which meshes with the spur gear e which 1s intermittently' driven by the continuously advancing actuator E. g2 g3 are mounted on shafts g* g, 'and are each provided with a hub for the purpose of brake engagement. The brake g is wedge-shaped and provided with .a plunger g". The brake is held to its work by means of a coiled spring g8. The plunger g7 is articulated to the lever f* Ywhich actuates the brake F and is actuated concurrently therewith. A drag brake g9 is shown (Figs. 3 and 4) continuously in engagement with the hub associated with the sprocket wheel G. 'A hand lever f7 (Fig. 6) is provided for raising the brakes when it is desired to rapidly feed forward'the paperfrom the roll by hand in setting up the machine or when it is desired to remove one roll and replace it by another. A catch f8 is lshown for engaging the hand lever and holding the brakes in their inoperative position.

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 above referred to. Upon the downward movement of the transferring devices the interposed sheets a 6 are placed upon thel 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 dotted lines in Fig. 5. After the stripper and the transferring 4device have been sufficiently advanced in their upward movement, the atrix H is advanced toward the formers The operation of the machine is substantially as follows z--The pasting and transferring devices illustrated operate substantially in the manner set forth in the Smyser patent above referred to and their operation will not, in this part of the description, be specifically'mentioned except in connection with the explanation of the associated parts, except to state that at time intervals thepastecovered feet c2 c`ome into position over; the ystack A'and descend and rise and advance. At each descent the paste-'covered 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 f orthe 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 mechanlsm. The shaft e5 for the actuator E of the sheet-supplying mechanism is shown driven by the same shaft which drives the cam shaft d for controlling the horizontal step-by-step movement of the pasting and transferring mechanism as well as its vertical movement for engaging the sheet and lifting the same. In the position illustrated in Fig. l the paste-covered feet c2 are at the end of their upward stroke, having descended upon a sheet a at the top of the'stack, having Iimposed upon it a sheet 6, leaving a margin a1 for the reception of the paste and Alifted the same. As is stated above, the feet 02 are of sufficient area to apply paste to this exposed portiona1 and to the adjacent edges of the imposed sheet 6. The next movement of the pasting and transferring mechanism is in a substantially horizontal plane, and during which movement the finger e9 of the actuator E is timed to come into engagement with the pin el which was advanced in its path just prior to its disengagement from the pin with which it was previously in engagement. This engagement between the pin e1 and the finger e9 causes the spur gear e to move forward 90 degrees, which forward movement,

. upon its inauguration depresses the roll f and removes the brakes from engagement with the hubs of the pinions g2 gaand from the friction face of the holder for the roll of paper stock B. The forward movement maaar;

ofA the parts is then permitted.- Thedriver and reciprocates the-pawl b3, thereby advancing thelroll carrier step by step and causing -the'vmaterial to unwind therefrom and be fedforward to theforwarding rolls which then push the paper .Forward over. the stack A. After a predetermined amount of paper has been fedforward the cam e13 runs olf the roller f5 whereupon the leverf, and the brakes respond to their respective springs and the actuating mechanismn and the paper-forwarding mechanism come to a standstill. The rollers b104 b positively position and hold the sheet until itis severed. At the time the cam runs oli theroll f". the pin el", which liasbeen engaged by the iinger e9 for imparting the forwardmovement to the spurwheel e", runs off its track e and is drawn out of engagement with the finger by means of its spring. At about the time the forwarding rolls b1 b1? have been brought to rest theA pasting and transferring device is in position over the stack andl is then caused to descend. In its descent the shear-actuating foot b20- engages theend of the shear b and severs the sheet which has been placed in position at the top of the stack, and the continued descent ofthe pasting device brings the feet c2 into engagement with the superposedsheets in the manner above described.- It isto be noted that the cam for effecting the unwinding of4 the paper from the roll B also controls the brakes for the roll and for the forwardingy mechanism for the material unwound.

It will be apparent that changes may be made in the mechanism within the scope of the claims without departing from the spirit of the invention.
