It is still another object of our invention to provide an automatic machine for making liquidtight paper containers in several sizes simultaneously, or selected ones of said assorted sizes. 1 Another object of our invention is to provide an automatic machine for making liquid-tight paper containers progressively and simultaneously in various steps.

vIt is another importantobject of our invention 4 to provide an automatic machine for making liquid-tight containers employing novel adhesive applying means, neck forming means and auto matic means for inserting and seaming the bottom of the container.

Another important object of our invention is to provide an automatic machine for making liquid-tight paper containers having ejector and conveyor means for the completed containers.

'The invention may be embodied in machines that vary in form and in structure, and are designed and constructed for use in continuously and automatically forming liquid-proof paper containers, such as milk bottles, from a roll of paper in either one size or various sizes.

While the principal objects of this invention are stated above, others will appear in the following specification describing the embodiment of.

the feed rolls.

The feed rolls I and 2 have at one end thereof axial extensions 5 and 6 journaled in. bearings I and 8 formed in the end frame 9; and

at their opposite ends these axial extensions are journaled in bearings l0 and ll provided in a transverse support l2. (See Figures 1, 2, 4 and 5.)

The end frame 9 is substantially square, having corner members l3 and it connected by transverse top, bottom and intermediate members [5, l6 and 11, respectively, reinforced and stiffened by ribs formed on their inner faces.

the end frame 9 is a right end to the former and having top,

Opposite frame I8, similar bottom and intermediate transverse members l9, 20 and 2| respectively, their inner faces.

likewise stiffened by ribs provided on The frames 9 and I8 are interand 2 adjacent their

bearings

1 and 8, areprovided with

mating gears

26 and 21, by which they are rotated in unison. (See Figures 1' and 2.)

which receives a V-belt 29 that passes over.a similar V-pulley 30 keyed to a main longitudinal drive shaft 3|, by which the feed rollers are rotated. (See Figure 5).

. The shaft 3| is journaled at each end in

bearings

32, 32 provided in the end frame 9, and another transverse support 33. Adjacent its center, the shaft 3| is connected through a gear reduction drive 34 with a motor 35, below it. This motor is mounted upon a bed plate 36 extending longitudinally of the machine and supported by the bottom transverse end frame members l6 and 20. (See Figure 2.)

Beyond the bearing'32 in the end frame 9 there are keyed to the shaft 3|, spaced

intermittent gears

31 and 38, adapted to mesh with

pinions

39 and 40 respectively above them. The pinion 40 is keyed to a sleeve shaft 4| journaled in an end frame bearing 42 and having secured to its other end a lock disc 43. Rotatably mounted within the sleeve 4| is another shaft. to whose outer end the pinion 39 is secured, and to whose opposite end another look disc 45 issecured. Co-acting with the

lock discs

43 and 45 are lock discs 46 and 41 respectively keyed to the shaft 3| adjacent the innerface of the frame 9.

The intermittent gear 31 has a pitch diameter four times that of the mating pinion 39, the

teeth of the gear 31 occurring on 2'10 degrees of its periphery and joined by an undercut portion 48. Likewise, the lock disc 41 has an undercut portion 41 co-extensive with the toothed portion of the gear 31. (See Figures 1, 2 and 4.) Formed n the periphery of the lock disc 45 engaged by the disc 41, is an arcuate depression 49 in which the periphery of the larger lock disc 41 is af-:

forded a clearance.

When the shaft 3| is rotated, the outer periphcry of the disc 41 will turn through the depression 49, and the pinion 39 and its lock disc 45 will be stationary, locked against-rotation, by the engagement of the lock discs 45 and 41.

Now, when. the toothed portion of the gear 31 engages the pinion 39, the latter will make three complete revolutions before the toothed portion passes out of engagement with it, and during 'its rotation, the periphery of the lock disc 45 will be rotated in the clearance afforded by the undercut portion 41 of the disc 41.

The gear 38 is like the gear 31, except that its teeth occur upon only 90 degrees of its periphery, the teeth starting in alinement with the teeth of the gear 31, and its respective lock disc 46 has an undercut portion 50 co-extensive with the toothedj'portion of the gear 38.

Whenthe shaft 3| is rotated, the gear 31. will cause its pinion 39 to make three complete revolutions and, starting simultaneously with the rotation of the pinion 39, the gear 38 will cause its respective pinion 40 to make only one revolution. (See Figures 1, 2, 4 and 5.)

Meshing with the pinion 39 is an idler pinion of equal diameter. Secured to this pinion is an idler gear 52. Meshing with the pinion 40 Mounted on the upper shaft 5 is a V-pulley 28 die rotatable with the is an idler pinion 53, also of equal diameter and having secured thereto another idler gear 54. The pinions 5|. and 53 with their respective gears 52 and 54, are freely mounted on a stud 55.pro jecting from the outer face of the frame 9. Meshing with the gear 54 is a gear 56 of like diameter and secured to the axial projection of the shaft 51 for the lower gauge and shear roll 4. The opposite end of this shaft 51 is journaled in a bearing 58 provided in the support l2 (see Figure 4).

Y Also meshing'with the gear 52 is a gear 59,

of like diameter, secured to the projecting end of a mandrel 60. This mandrel 60 is received by an axial housing 6| formed in the top member l5 and in which it is journaled in spaced ball bearings 62 and outer faces.

It is evident that the continuously rotating feed rollers and 2 will draw the paper into the machine constantly as used. (See Figures 1, 4 and 5.)

The intermittently turning gauge and shear rolls 3 and 4, being slightly larger than the mandrel, will make one complete revolution, thereby introducing a length of paper sumcient to form an overlapping layer upon the mandrel 60, said over-lapping portion forming a longitudinal adhesive coated seam to be hereinafter referred 'to.

Longitudinally positioned in registering positions on the periphery of the rolls 3 and 4, are co-acting rotary shear blades 64 and 65 which, with each revolution of these rolls, will sever the lsength of paper above referred to. (See Figure The introduction of the piece of paper required to form the container occurs during a single complete revolution of the rolls 3 and 4.

and 63 in counterboresin its inner This paper is then received by a forming cylinder 66 adjacent the roller 4. The cylinder 66 is rotatably mounted with the mandrel 60, and consists of a cylindrical sleeve 61 supported, adjacent the bearing 63, upon a flange 68 surrounding the mandrel 60. At its opposite end the cylinder is supported upon another flange 69 at the inner unsupported end of the mandrel.

Axially slidable within the mandrel 60' is an ejector shaft 10 whose one end extends through the 'end of the mandrel beyond the gear 59. To the inner end of the shaft 10 there is secured a conical end member 1| shaped to form the neck of the container as shown in Figure 16. This conical end member is essentially a male rotary mandrel 60 and having formed on its periphery spaced axial ribs 12, va-

rying from their maximum height at the outer reduced end of the conical end member 1|, to their inner end, where the ribs converge with the surface of the conical end member.

Formed in diametrically opposite sides of the wall of the cylinder 61, between the flange 69, and terminating in the conical end 1|, are axial slots. In these slots are positioned transfer bars 13, 14 whose outer faces are finished flush with the cylinder. At one end these bars are secured in continuations of the slots in the conical end member 1| and at their opposite ends they are attached to a 'spacer ring 15, between its flanges 68, slidable.

Also surrounding the cylinder 66 at the end of the

bars

14, 14 and adjacent the flange 66, is an ejector ring 16. This ring is provided with opposite inwardly projecting studs 11, 11 that are secured to another slidable ring 18 surrounding the 69, and over which it is surrounding the mandrel 60,

mandrel 88, between its flange 68 and the ring I5. Secured to he ring I8 and projecting inwardly therefrom, is an actuating stud 19, that passes through an axial slot 88 in the wall of the mandrel, where it enters a short slot 8| formed in the ejector shaft I8. (See Figures 4, and 14.)

When the shaft 18 is moved axially of the mandrel, in a manner presently to be described, it will project the conical end member II to the right of the position shown in Figure 4. When the end of the slot 8| engages the stud 19, it will also carry the ejector ring I6 axially of the cylinder 66, toward the right as shown in Figure 4.

As above set forth, the paper is received by the revolving roll 66 during its first complete revolution, and as its trailing edge passes towards this roll, between a lower guide plate 82 and an upperguide plate 83, an adhesive is applied to the under or inner face of its overlapping, seamforming portion by an adhesive brush 84. This adhesive brush 84 may be of any suitable ab sorbent material that will,'by capillary attraction, convey the adhesive'from a container support 85 below it, to the contacted surface of'the paper.

The support 85 is essentially an elongated container in whose top face the brush is secured and pivotally suspended by

arms

86, 88 from an angle support 81 beneath the plate 82. (See Figure 14.) Connected with one of the arms 88 by a link 88, is a cam follower arm 88 whose outer end bears on the periphery of a cam 89 and is timed to bring the adhesive brush into contact with the paper as its trailing end passes over the brush. (See Figure 5.)

In order to insure the perfect forming of the paper into a cylindrical form upon the cylinder 66, we have provided co-acting pressure rollers 98 and arcuate guide plates 9| spaced about its periphery. The rollers 90 are covered with a yieldable material such as semi-hard rubber, and each has axial extensions, rotatably received by pivoted bracket members 92 at each end thereof.

As shown in Figure 5, these bracket members are essentially rocker arms pivotally mounted at their centers on radial bosses 93 formed on the cylindrical housing 6| at one end of these rollers.

At the other ends of the rollers, the rocker arms 92 are pivotally mounted on bosses 94 circumferentially spaced about the cylinder 86 and provided on the transverse support I2. Projecting outwardly from adjacent bosses 93, and in parallelism, are lever arm extensions 95 of the rocker arms, whoseouter ends are connected by link members 99, so that when one rocker arm 92 is rotated to move its respective roller 98 away from the cylf der, all of the rollers will be simultaneously moved. (See Figures 4, 5 and 14.) Beyond its respective roller 98, each rocker arm 92 has an extension 91 between which are secured the arcuate guide plates 9|, that, like the rollers 98, are all movable,with the rollers towardor' away from the cylinder 66.

Integral with one of the lower rocker arms 92 is a cam follower arm 98, whose lower free end engages a cam 99, rotatable with the shaft 3|.

As previously .described, during the first revolution of the cylinder 86 or mandrel 88, the strip of paper delivered to it by the gauge and shear rolls 3 and 4, will be formed into a cylinder, with its overlapping edges cemented. During the two subsequent revolutions of the cylinder 68, the co-acting rollers 98 and guide plates 9| by their pressure, will complete the adhesion of the overlapping portions of the paper cylinder. The ends of this complete cylinder, comprising the first operation, are indicated by dotted lines A in Figure 4 and shown in Figure 15. I

In order that the container may be completely sterilized I have provided within the cylinder 66 and attached to its walls by countersunk screws, electrical heater units lit -458 encased in a moulded, heat-resisting insulating compound. These units are essentially semi-circular in cross section and are positioned within the cylinder 66 below 'the rollers 98. Current is conducted to the heater units by insulated conductors 88 -436 that terminate at collector rings 6666 on the outer end of the mandrel 68 beyond the end frame 8. Current carrying brushes EF -66 mounted on the latter and connected by wires 6B-96 with a source of current (not shown), contact the collector rings 6666 to complete the circuit. The heated mandrel in contact with the inner cylinder walls, thus renders it sterile.

When the cylinder 66 is stationary, due to the action of the intermittent gear 31, the cam 99 will be so timed to'actuate the rocker arms 92 to move all of the rollers 98 and guide plates 9| away from the cylinder 66.

At this time the ejector shaft I8 will be moved axially and the ejector ring 18 will slide axially along the cylinder 68 and under the now disengaged rolls 98 and guides 9|. By this action the paper cylinder previously formed is moved to the right as shown in Figure 4, to bring its one end into position in alinement with the rotary die II as indicated by the dotted line B, the opposite end of the now completed paper cylinder being engaged by the ejector ring 16. The ejector ring I6 will now be returned to its position as shown in Figure 4, and a second paper cylinder will be formed, simultaneously with the second forming action, later to be described.

The reciprocating movement ofthe ejector shaft is accomplished by the following means. (See Figures 4 and 5.) Secured to. the outer end of the shaft I8 beyond the gear 59 is a yoke member I88, vertically positioned and having attached to its lower end an actuating rod IDI, that proj ects laterally through the transverse member I6, below the mandrel 68. Attached to the inner end of the rod I8I is an apertured slide member I82, slidably' positioned on a fixed rod I83. This rod is supported between the end frame 9 and. the transverse support 33.

Formed on the top of the member I82 is a roller stud I84, received in the forked end I85 of a cam lever I86. The latter, at its opposite end, is pivotally attached to a boss I81 provided on the rear longitudinal member 24. (See Figure 5.)

Intermediate the ends of lever I85, we have provided on its under side a cam stud I88, received by a cam slot I88 on the periphery of a drum cam I89 below it. The latter is keyed or otherwise secured to a shaft Illl whose ends are journaled in the end frame 9 and transverse support 33.

By means later to be described, the cam I89 is imparted a continuous rotation at the same speed as the shaft 2|. Since one paper cylinder is formed upon the cylinder 66 for each revolu- When the cylinder 66 comes to rest the seam or adhesive joint will be positioned under the top roller 9-0, and as the paper cylinder is moved to the right this seam will be passed under a spring tensioned, knurled roller H2 positioned above the cylinder 66 and whose sharp ridges or teeth will firmly unite the over-lapping edges of taneously with the performance of the first operation on a succeeding container and "the completion ,of a third operation, later to be described. It is by such progressive steps that faster production is accomplished. Three containers, in various stages are constantly in progress of manufacture.

When the completed paper cylinder above described is transferred to the right, to the dotted line position indicated by the letter B in Figure 4, its upper end, surrounding the conical male die 1I, will be engaged by a co-acting conical female'die' I I4 similar to the die 1I. rotatable in synchronism with the die H, is pro- ,vided with a like number of circumferentially spaced axial slots II5 which, meshing with the ribs 12, reduce the paper cylinder to a ribbed conical' neck, the surplus paper being absorbed in forming the ribs thereon. (See Figures '4, 6 and 12.)

The die II4'as shown at Figure 4, has integral with its larger end an axial extension II6 journaled in spaced bearings H1, H1 provided in a swivel bracket I I8. Between the bearings there is keyed to the axial extension a helical gear I I9 by which the die is rotated. (See Figure 13.)

Adjacent the gear H9 is a vertical shaft I20 at right-angles to the axis of the die, and having thereon another gear I2I like the gear H9 and meshing 'therewith. The shaft I20 is journaled in a bearing formed in the bracket 8 and it also has keyed thereto, and at the lower end thereof, a gear I22.

Integral with the bracket I I8 is a boss I23, having therein a vertical aperture I24 in which a short vertical shaft I25 is received and about which the bracket is rotatable. This shaft I25 is journaled in elongated bearings I26 provided on a plate I21, secured between the supports I2 and 33, below the mandrel 66. Secured to the vertical shaft I25 betweenits bearings I24 and I26 is another gear I28 meshing with the gear I22.

(See Figures 4 and 13). When the shaft I25 is rotated by a means presently to be described, the female die will be rotated through the gears I22 and I28, and H9 and I2l.

It is evident that the bracket H8 is rotatable about the vertical shaft I25 away from and out of engagement with the die H, to permit the entry of the paper cylinder over the mandrel 66. When the paper cylinder is properly positioned, the female die II4 will be forced into engagement with the die H by a timed cam I29 on the shaft H0 and -rotatable with it. Formed in the periphery of this cam is a cam slot I 30, engaged by a cam roller I3I carried in the outer free end of a lever arm I32 integral with the bracket I I8. Upon completion of the neck forming operation, this cam will rotate the female die away from the male die 1 I. (See Figure 4.)

This die II4,

Rotation is imparted to the vertical shaft I25 by a horizontal shaft I32 parallel with the.

mandrel 66, and journaled in bearings provided for it in the end frame 9 and support I2.- Secured to the end of the shaft where it projects beyond the support I2 i a spiral gear I33 meshing with a like gear I34 on the upper end of the shaft I25. (See Figures 2, 4 and 13.)

Keyed to the opposite end of the shaft I32 outside of the end frame is a gear I35 of the same size as the gear 59 with which it meshes. When the gear 59 is rotated to turn the mandrel, it will 'also rotate the shaft I32 and, with it, the female die II4 to form the tapering plaited neck of the container as the dies are moved into co-acting engagement by the cam I29.

Simultaneously with the formation of the tapering plaited neck of the container as above described, -I haveprovided the following means to finish the neck and to form a cap seat at the end of the neck as shown in Figures 9, 10 and 15. The neck finishing and seat forming operation is accomplished in two stages, first by a neck fianging spinner I36, and finally, by a seat forming spinner I31.

Referring now to Figures 4 and 9, the neck fianging spinner. I36 consists of a revolving tubular sleeve I38, having adjacent one end a flange I39 rounded at its outer edge. Beyond the flange the sleeve corners are rounded to form a slightly tapered tenoned end I 39 This sleeve I38 is ro-' tatably mounted in a bearing bushing I40 and is retained against axial movement by a V-pulley I4I secured to the end of it, opposite the flange The bushing I4!) is mounted in the outer free end of a spinner arm I42, whose opposite end terminates in a hub I 43. Also extending from the hub I43 is another spinner arm I44 positioned 90- degrees circumferentially from the arm I42, and in whose outer end the seat forming spinner I31 is rotatably mounted in a bearing I45.

As shown in Figure 10 this seat forming spin-- ner comprises a tubular sleeve I46 to one end of end of which a double V-pulley I52 is attached.

At its opposite end the sleeve I 5| has a flange which, with the pulley, will retain the hub and bearing upon it.

One face of the hub I43, opposite the pulley I52 is turned down to form a shoulder I53 concentric with the bearing and on which a gear I54 is secured. Beyond the gear the shoulder I 53 has therein a groove I55, engaged on opposite sides by the forked end I 56 of a shifter arm I51.

Formed in the inner wall of the sleeve I5I is a keyway to receive a key I58 rotatable with a spinner drive shaft I59, and over which the sleeve is slidable. The shaft I59, supported in parallelism with the mandrel 66 and in horizontal alinement with it, is journaled in bearings I 66 and I6l carried by the support 33 and end frame I8 respectively. (See Figures 1, 4 and 6.)

Below the shaft I59, parallel therewith and likewise rotatable in bearings provided in the support 33 and end frame I8, is a counter shaft I62. Secured to this shaft is a gear I63 of the same diameter as thegear I54, with which it meshes. Keyed to ahub projection on the face of this gear is a slotted spider I64 of a conventional Geneva gear drive.

Co-acting with 90 degree spaced slots I65 formed in the spider I64 is a stud I66 carried by a Geneva gear disc I61 below the spider. This gear disc I61 is keyed to a drive shaft I68, below the shaft I62 and in axial alinement with the shaft I2, likewise journaled in bearings provided for it in the support 33 and end frame I8.

Also mounted on this shaft I68 and against the 'face of the disc I61, below the spider I64 is a lock plate I69. It is generally understood that when the stud. I66 has effected the desired quarter turn of the spider I64, it will pass out of engagement with one of the slots I65 and then the periphery of the lock plate will turn through a circular clearance I10 provided in the periphery of the spider I64 between its spaced. radial slots. When one of the circular clearances I10 is so engaged by the lock plate the spider can not be rotated in either direction. Now, as the stud I66 is rotated with the disc I61, it will re-enter a succeeding slot I65 to again rotate the spider and its gear I63, and the spider will rotate through a depression I1I formed in the periphery of the lock plate I69. (See Figure 6.)

When the gear I63 and its meshing gear I54 are thus rotated step by step at 90 degree intervals, first the neck-forming spinner I36 and then the'seat-forming spinner I31 will be successively presented at the end of the mandrel 66. When the neck-forming spinner is positioned at the end of the mandrel, it will be advanced toward the end of the latter, as the co-acting rotary dies form the tapering neck; and when in full engagement, the female die will form the neck outwardly as shown by the dotted lines in Figure 9.

Due to the revolving spinner, this operation is rapidly accomplished and as this spinner I36 recedes from its advanced position, the Geneva gear will quickly'rotate the spinner hub to bring the seat forming spinner I31 into position before the endof the mandrel 66, and it will be advanced to turn down the flange previously formed as indicated in Figure 9 and thus produce the completed cap seat as indicated by the dotted lines in Figure 10. Each of the spinners I36 and I31 is revolved by belts I12-I12 passing over a respective V-pulley and one of the grooves of the double V-pulley I52. I The endwise movement is effected in timed relation with the positioning of each spinner at the end of the mandrel by the following means. (See Figures 1, 4 and 6.) The shifter arm I51 'is rotatably mounted on a vertical shaft I13 journaled in upper and lower rib stiffeners on the support 33. Below the arm I51 there is also secured to the shaft I13 a cam follower arm I14 whose outer end engages a cam surface I15 provided on the face'of the disc I61, opposite the stud I66. Also integral with the arm I51 and projecting at right angles therefrom, is a lever arm I16 projecting through an opening in the support 33. Secured to the outer end of this arm is a tension spring I11 whose opposite end is anchored to a stud secured to the support 33.

When the spinners are successively brought into operating position, one of the cam lobes I15 on the constantly rotating disc I61 will engage the cam follower arm to move the spinner against the container neck as previously described. When frame I8.

the cam lobe passes out of engagement with the cam follower, the spring I11 will cause the spinner to back away from the mandrel prior to indexing.

Rotation of the shafts I59, I62 and I68 is effectcd by the followingmeans. Keyed or otherwise secured to the end of the shaft 3I adjacent the support 33 is a gear I19 meshing with a pinion I secured to the end of an idler shaft I8I. This shaft is journaled in a bearing in the support 33 and has secured to its opposite end another gear I82 similar to the gear I19. Meshing with this gear is another pinion I83 secured to the shaft I68. By this train of gears, the shaft I68 is rotated at four times the speed of the shaft 3 I.

Now, for each revolution of the shaft 3I the shaft I62 will also make one complete revolution intermittently, due to the Geneva gear previously described. Mounted on the end of the shaft I8I, adjacent the pinion I80 is another gear I84, also meshing with a gear I85 freely mounted on the end of the shaft I62 where it projects through its bearing in the support 33. This gear functions as anidler and meshes with another gear I86 secured to the end of the shaft I59 above. By these gears I84, I85 and I86, the shaft I59 is rotated at high speed and the spinner I36 and I31 at a corresponding high speed.

When the neck and cap seat forming operations, constituting the second stage are thus completed the cap seat forming spinner will be rotated degrees and the die I I4 will drop back. When these tools are thus cleared, the ejector will move to the right in the manner previously set forth and in this instance the conical male die 1I will carry this completed container body as shown in Figure 16, fartherto the right, to the dotted lin position indicated at C in Fig ure 4.

When the container is thus transferred for the final operation, to wit, the insertion and crimping of the container bottom, it is received within a sleeve'I81. This sleeve is mounted within a cylindricalhousing I88 in alinement with the mandrel 66 and supported in the end (See Figures 3 and 4.)

At its center this sleeve has integral therewith a split clamp member I89 whose adjacent ends are provided with depending apertured lugs I90, I90, that project below the wall of the housing I88. Passing through the lower ends of the lugs I90, I90 is a clamp stud I9I whose enlarged end is formed with a cam face I92 which engages a like faceprovided on one of the lugs I90.

Attached to the stud I9I is a short lever I93 to ,whose outer end an actuating rod I94 is connected. rotated by the lever I93 and rod I94, the coacting cam faces on the stud and one of the lugs, will bring the ends of the split clamp members together to restrict its opening, to thus hold securely the container inits deposited position.

(See Figures 1 and 4.)

The lateral movement of the rod I 94 is effected by the movement of the actuating rod IOI in the following manner. Slidably positioned on the rod I03, between the member I02 and the adjacent end frame 9, is a collar I94 to which the end of the rod I94 is secured. Attached to the latter and near the opposite end frame I8, is a collar I94 to which one end of a tension spring I94 is fastened. The opposite end of this spring is anchored to the end frame I8. (See Figure 4.) a

When the actuating rod IOI is moved to the right, as viewed in Figure 4, the member I02 will move along the rod I03, and the spring I94 (See Figure 1.) When the stud iswill then move the rod. I94 also to the right, sliding the collar I9 I along the rod I03 and. effecting a release of the container held within the clamp member, I89. When the actuating rod is returned to the left, the member I02 will engage the collar I9 I and also move it to the left, effecting a rotation of the clamp stud I! through the leverarm I93 attached thereto, and thus tightening the clamp member I89 about the unfinished container positioned within the sleeve.

Rearward of the sleeve I81 and likewise positioned in a housing I95 supported in the end frame I8 in this housing I95, we have provided a magazine I96 for the preformed container bottoms, and from which they are fed by spring pressure means. Between the sleeve I81 and the magazine I96 is a horizontal shaft I91 whose ends are journaled in bearings provided for it in the end frame I8 and the support 33.

Freely mounted on the shaft I91 and intermediate its end bearings, is a slidable sleeve I99 rotatable about the shaft. Attached to one end of this sleeve adjacent the support 33 is a gear 200, and to its opposite end, the hub 20I of the bottom transfer and crimping devices is attached. Projecting radially from this hub, and from diametrically opposite sides thereof is a transfer arm 202 and a crimping head arm 203.

Slidably mounted on the sleeve I 99 is a collar 204 having. integral with one end thereof, spaced flanges to form between them a groove 205. At its other end, studs 206-206 project from up site sides of the collar 204.

Formed on the outer end of the transfer arm 202 is a boss 201, having-therein-a flanged bushing 208 as shown in Figure 11, and in axial alinement with the shaft I91. At one end, adjacent the end frame I8, the aperture 209 in the bushing is flared to form a tapering seat for a sliding-sleeve 2II positioned within it. Beyond the endof the bushing the sleeve 2 is flanged,

and to which a flanged transfer disc 2I2 is riveted. This disc and one end of the sleeve to which it is attached are split, to form a yieldable structure, which, when the sleeve .2 is drawn into the tapering seat, will constrict-the diameter of the disc. (See Figures 4 and 11 Secured to the opposite end of the'sleeve 2 where it projects beyond the opposite face of the boss 201, is a collar 2I3. This collar is engaged by an actuating arm 2 having spaced fingers 2I5, 2| 5 which straddle the sleeve between its collar and the boss 201, and a center finger M6 to engage the opposite face of the collar 2I3 at the end of the sleeve.

Formed on the arm 202 between the boss 201 and its hub 20I, is a slotted boss 2I1 in which the arm 2I4 is pivotally mounted. At its inner end the arm 2I4 is forked and provided with oppositely positioned studs 2? that engage in the groove 205. Now, when the transfer arm is positioned before the magazine I96, it will be advanced toward the magazine with the transfer disc 2I2 contracted. When the arm reaches its advanced position, the actuating arm 2 will force the sleeve I99 out of its tapering seat 2I0, and the disc 2I2 will automatically expand to grip the inner face of the flange provided on the fore the magazine.

tapering seat to release the flanged disc 2I2 from the container bottom as the-transfer arr'n 202 backs away. I

The rotation'of the transfer arm 202 and .the

crimping head arm 203, as well as the movement of the actuating arm 2 is accomplished by the following means. (See Figures 3, 4 and 6.) Keyed to the shaft I68 adjacent the end'frame I8 is a helical gear 2I9 that meshes with another helical gear 220, positioned at right angles with the gear 2I9 and keyed'to a transverse shaft 22I. This shaft 22I is positioned at the front of the machine in a bearing 222 supported by the intermediate transverse member 2I of the end frame I8. At its rear end this shaft 22I is journaled in another bearing 223, likewise supported by the member 2|. Adjacent the bearing 223 there is attached to' the shaft another helical gear 224,and-driving a like gear 225 positioned above it, at right angles to the gear'224. The gear 225 is keyed to a shaft 226 parallel with the shaft I 91 and journaled in the support 33 and end frame I8. (See Figures 3, 4 and 6.)

By these gears the shaft 226 is rotated at the same speed as the shaft I68. Also the shaft H0 226 by a pinion 226* on the shaft 226 and a gear 226 on the shaft I I0. Keyed to the shaft 226 is a drum cam 221, having formed in its periphery substantially parallel cam slots 228 and 229, by which the actuating arm 2I4 is operated and the hub 20I shifted axially of the shaft I91.

Engaging in the cam slot 228 is a cam lever 230, actuated thereby, and pivotally mounted on a vertical shaft 23I mounted in the support 33. At its opposite end the lever is forked, and its forked ends slotted to receive therein the

studs

206, 206 of the sleeve 204. (See Figure, 4.)

Engaging thecam slot 229 is another cam lever 232, likewise pivotally mounted on the shaft 23I. In a cylindrical boss 233. at the opposite end of the lever 232, we have provided a slotted bush-' As previously described the bottom is inserted I in the open end of-the container'by the transfer head and then the hub 20I is again rotated, this time, to position the crimping head before the unfinished bottom and the transfer head he- The indexing of this hub is accomplished by the gear 200, which meshes with a like gear 235 below it. This gear has a hub extension 236, to whose opposite end another gear 231 is secured. These gears are freely mounted on a stud 238 carried by the support 33. (See Figure 4.)

Meshing with the gear 231 is an idler pinion 238 carried by a stud 239 and also meshing with the gear I63 on the shaft I62 and by which the shaft I59 is also rotated. (See Figures 4 and 6.) Since the gears 200 and 235, and the gears 231 and I63, are ofthe same diameter, the spinners I36 and I31, and the transfer and crimping heads,

will be rotated in synchronization to alternately position these before the container as it is formed.

It should be noted that these respective heads are indexed 90 degrees at one time, and during one quarter of the cycle.

When the

arms

202, 203 are positioned vertically and the spinner I36 is below the shaft I59, the space between the mandrel 66 and the sleeve I81 is clear. During this period the actuating arm eifects the transfer of the partly finished container from B to the sleeve I81.

The final operation, to wit, the crimping of the bottom in place will now be described. Formed on the outer end of the arm 283 is a boss .248 provided with an aperture parallel with the shaft I91. Positioned in the aperture is a bushing 24l, in which there is rotatably mounted a sleeve 242. Secured to one end of'this sleeve is a spider 243, and to its opposite end, a collar 244 by which the sleeve is retained within thebushing 24I. (See Figures 4, 7 and 8.)

Rotatably positioned within the sleeve 242 is the hollow shaft 244 of a gear 245, positioned against the face of the spider 243. At the end of the shaft, opposite the gear, there are opposite, inwardly projecting

pins

246, 246 received in double spiral grooves 241, 241 formed on an actuating rod 248, slidable within the shaft 244. The rod is prevented from rotating by a key 249 projecting inwardly from the sleeve 242 into an axial keyway 259 provided in the enlarged outer end of the rod 244. Beyond the endof the sleeve the rod is provided with a reduced neck portion 25I, that is engaged by an actuating lever 252, and by which it is moved axially to rotate the gear 245 in opposite directions. (See Figures '7 and 8.) The lever 252, like the arm 2l4, is pivotally connected at its center to a boss 253 formed on the arm 263. At its opposite end the arm is forked to engage the groove 205 on the sleeve 204. Formed in the spider 243, in axial alinementwith the sleeve 242, are four apertures 254 spaced 90 degrees circumferentially about its center. Rotatably mounted within each aperture 254 is the reduced end of an eccentric shaft 255, having an enlarged outer end 256 eccentric with it. Be-

tween the enlarged and reduced ends of each shaft 255 we have provided a D shaped shoulder 251 slightly larger than the shaft 255 and concentric therewith. Positioned upon the shoulder 251 of each shaft is a gear 258 that meshes with the gear 245.

Positioned upon the enlarged end of two of the diametrically opposite shafts are knurled.

rollers

259, 259. These rollers have at their outer ends a flange 266 as shown in Figure 8. Beyond each of these opposite shafts 255 there is provided in the spider another aperture in which an outer shaft 26I is rotatable. .1 These shafts are in all respects like the shafts 255 and have freely mounted on their

outer ends rollers

262, 262. Formed at the outer end of each roller 262 is a wide flange 263, reduced at its outer face to form a stepped shoulder 264. Between the roller and the spider, each of these shafts has thereon a gear 265 that meshes with a respective gear 258 carried by a respective inner shaft 255.

When the shafts 255 and. 26I are rotated in unison by the center gear 245, the eccentric outer en'ds will move their

respective rollers

259 and 262, either together to form the engaged flanges of the paper container and its bottom at right angles to its sides, or move them apart as shown in Figure 8. I

Freely mounted on the eccentric shoulders 256 of the shafts 255 intermediatethose carrying the rollers 259, are rollers 265. These rollers have by the spider.

provided at the outer ends of shafts 216. These shafts 216 are similar to the shafts 255', being freely mounted in apertures formed in the spider 243 beyond the inner shafts 255.

Positioned on each shaft 216 is a gear 21I that meshes with the gear 258 provided for the'

adjacent shafts

255, 255, which gears also mesh with the center gear 245. When the gear 245 is rotated, the gears 2H and 258 will rotate their respective

eccentric shafts

255, 255 and 210, 210 to bring their

respective'rollers

265, 265 and 268, 268 together or apart depending on the rotation of the gear 245. When these rollersare brought together, they will form the right angle, flanged bottom seam inwardly, and firmly crimp these edges together to. complete the seaming operation. These rollers are shown together in Figure 8.

When the actuating rod 248 is partly withdrawn from" the hollow shaft 244, its spiral 2 advanced against the inserted bottom positioned within the container cylinder. When the spider is fully advanced, the cam slot 228, through the

levers

230 and 252, will withdraw the actuating rod 248 to its extreme outer position and thus bring the

rollers

259, 259 and 262, 262 together to perform the first seaming operation on the container bottom. Also the transferdisc will be inserted in the container bottom in the magazine I96, but contracted out of engagement with the bottom.

When the first seaming operation is completed, the actuating rod 248 is forced inwardly to rotate the gear 245 in a reverse direction. The

rollers

259, 259 and 262, 262 will now be separated, and the

other rollers

265, 265 and 268, 268 will be brought together as previously described to complete the seaming operation. The transfer disc, which is still inserted in the container bottom in the magazinewill now be expanded to grip it.

Uponcompletion of the last seaming operation, to produce the container as shown in Figure 17, the actuating rod 248 will be partly withdrawn again to release all of the forming'rollers carried The cam 229 will now move the hub 2Il'I axially, and with it, the crimping head and the transfer head away from the sleeve and (See Figures 214 keyed to the shaft I91 by which it is rotated.

(See Figures 4, 7 and 8.)

Secured to the outer end of the shaft I91 beyond the end frame I8 is a gear 215. This gear meshes with an idler pinion216, rotatable on a stud 211 carried by the end frame I8. Meshing with'this pinion is a larger gear .218 having attached to its outer face a pinion 219. This gear 218 and pinion 219 are also rotatable above a stud 286 secured to the outer face of the end frame.

The pinion 219 is rotated by a larger gear 28I,

keyed to the outer end of the shaft 226 beyond its plaited neck and the cap sea the hub carry 7s bearing in the end frame. (See Figures 3 and 4.)

Following the bottom seaming operation, the clamp member I89 is released, as previously described, and as the ejector moves to the left, the end of the die 1 I, carried thereby, will engage the bottom of the completed container and force it out of the sleeve I81. When thus ejected, the completed container may be conveyed through closed tubes or chutes 282 indicated by the dotted line in Figure 4. These tubes may be used to deliver the completed container to a bottle filling and capping machine as ordinarily used by the milk bottling industry, thus rendering it unnecessary to handle them. Also if desired, these delivery tubes may also divert the completed containers to storage means for future use.

,The process or operations involved in the manufacture of a single container are as follows. The paper from the supply roll (not shown) is continuously drawn into the machine by the feed rolls I and-2, which delivers it to the gage and shear rolls 3 and 4 behind them. These rolls 3 and 4 rotate intermittently to make one complete revolution to advance and sever a strip of paper suificient to form the container cylinder with an overlappinglongitudinal seam. As the paper is thus advanced by these latter rolls 3 and 4, it

passes between upper and lower guide plates to a mandrel 60, and as the trailing edge ,of the sheet passes between these plates, an adhesive is applied to it to form a liquid-tight longitudinal seam.

The mandrel 60 is likewise intermittently operated, starting simultaneously with the rolls 3 and 4 to receive the paper advanced by them. However, after the adhesive coated edge passes to the mandrel, the latter makes two complete revolutions, to perfect, under the pressure rolls 90 and guide shoes 9|, the longitudinal seam.

After the mandrel 69 comes to rest the pressure rolls 90 and shoes 9I are moved out of contact with it by the cam 99. When the mandrel. 6-0 is thus disengaged the cam I09, rotating in timed relation with the mandrel, will move the ejector shaft 10 to the right, whereupon the ejector ring 16 will move the completed paper cylinder, shown in Figure 15, to the right to the positionindicated by the dotted line B in' Figure 4. As the paper cylinder is moved along the mandrel 60, its longitudinal seam will pass under the spring tensioned knurled roller I22, which further compresses it.

For the purpose of sterilizing the container, the electric heater units 66 -66 will maintain the mandrel at a sufficiently high temperature to destroy all bacteria upon the surface of the paper during the time that the cylinder is being formed.

After the paper cylinder is moved to the position B, the ejector ring 18 will be returned to its normal position and the cam I29 will bring the dies I I 4 and II into co-operative engagement when the mandrel 69 and the cylinder upon it are again'rotated, to form the tapering plaited neck of the container. While the die I I4 is advancing to form the neck of the container, the spinner I36 will be moved against the end of the die 1| to perform the flanging operation on the end ofthe container. As soon as this first neck operation is finished, the cams I15 will cause the spinner I36 to retreat and the Geneva gear mechanism to bring the second spinner I31 before the die 1I to turn down the flange to form a cap seat on the container, leaving it in the form shown in Figures l6 and 17.

With .the completion of the forming of the ing the spinner arms, will rotate the latter to a 'the unfinished container vertical position and the mandrel 60 will again come to rest. When the rotation of the mandrel has ceased, the ejector shaft 10 carrying the die 1I will again .move to the right, the die 1I this time conveying the now-completed paper cylinder to its extreme right-hand position, as indicated by the dotted lines C in Figure 4, within the sleeve I81.

The withdrawing die 1I will leave the cylinder within the sleeve I81. When the ejector shaft has reached its normal position, the slide member I02 will force the collar I9 3 toward the left and thus lock the paper cylinder within the sleeve I81, ready to receive the container bottom.

The transfer head shown in Figure 11, while contracted, will enter the magazine I 96, where, when expanded,it will grip one of the flanged container bottoms therein. This transfer head then drops back, through the action of its cam 229, and A by the same Geneva gear before referred to, it is revolved to a position before the end of the sleeve I81. The transfer head is again advanced to deposit the container bottomwithin the open end of the paper cylinder at its position C indicated in Figure 4. When thus deposited, the transfer head will be contracted by the cam 228 and again withdrawn by the *cam 229. The crimping head will now be rotated to operative position at the end of the sleeve I81 and advanced against the container bottom.

When this crimping head is rotated by the gear 2M, the

rolls

259 and 282 will co-act to perform the first operation, and when they are disengaged, the form rolls 265, 288 will be moved together to complete the bottom crimping action.

The hub 20I is now rotated to place the trans- I fer arm and crimping headarms out of position before the sleeve I81. This operation is simultaneous with the indexing of the spinner heads,

I36, I31, thus permitting an unobstructed travel for the ejector shaft and the die 1I carried thereby.

When the ejector shaft 18 is again advanced, carried thereby will engage the bottom of the completed container to force it out of the sleeve.

From the foregoing detailed description, it is evident that we have produced efficient and com- .pact means for forming liquid-tight containers in a. continuous manner by coordinated steps, said containers, excepting the pre-form'ed bottoms being manufactured from a roll of paper fed into the device.

In Figure 18, we have disclosed a multiple ma- 'chine in which we propose to manufacture simultaneously containers in three different sizes, such as quarts, pints and half-pints. This machine comprises a series of container producing unitsas disclosed in Figures 1 to 14 inclusive, and designated herein as a quart bottle producing unit 283, positioned in the base of the device. Positioned above the unit 283 and connected to the frame thereof is a pint bottle producing unit 284. Above this unit we have shown a smaller unit 285 for the production of half-pint containers. For the purpose of clarity, a detailed description of each unit will be omitted, their operation being in all respects like the single unit previously described. I Y

In Figure 18 we have shown a delivery tube or

chute
