BERG, OF NEW YORK, N. Y., ASSIGNOR, BY MESNE ASSIGNMENTS, T SEAL- CONES, INC., OF NEW YORK, N. Y., A CORPORATION OF DELAWARE APPARATUS FOR MAKING RECEPTAOLES Application filed October 19, 1929. Serial No. 400,944.

This invention relates to apparatus for forming or assembling paper receptacles of truncated conical formation, and particular- 1y to tubular holders to releasably enclose formed receptacle bodies, which holders are mounted on a carrier operative to successively position the receptacle bodies to means for forming, insertingand securing a'closure or bottom disk in the larger end of the receptacle bodies and to a position for eject- I ing the completed receptacles from the holders, and it is an object of the invention to provide improved holders for this purpose and an adjustable mounting therefor on the carrier to correctly aline the larger end of the receptacle bodies in the holders relative to the closure forming and inserting means and the closure securing means ,to compensate for Variations and wear in the parts.

The holders comprise longitudinal sections, and it has heretofore been the practice to mount the holder sections upon the carrier therefor whereby both sections are movable relative toeach other into and out of mating relation, the sections being normally urged out of mating relation and means being provided to normally maintain the sections in closed position, and it is another object of the invention to provide an improved mounting arrangement for the holder sections whereby the one holder section is mounted in fixed position on the carrier and the other section is pivotally carried by and normally urged into mating relation with the fixed section, and to provide novel and positively operated means for moving the movable section aw'ayirom the fixed section to release the receptacles from the holders after the closure disks have been secured therein.

-It is a further object of the invention to provide novel means operative by the movement of the movable holder section from the fixed section to release the completed receptacles from the holder sections.

Other objects and advantages will hereinafter appear.

The embodiment of the invention illustrated comprises a "rotatable carrier in the form 50 of a disk intermittently operated to succesin receptacle enclosing position. a plan view showlng the arsively position one of a series of holders equidistantly spaced about and extending radially of the carrier to means for forming, inserting and securing a closure disk in the larger end of truncated conical receptacle bodies carried by the holders and to a position to eject the receptacles from the holders. Each of the holders comprises a pair of semi-circular and pivotally connected sections with one of the sections supported in fixed position on the carrier and adapted to have adjustment circumferentially, radially and vertically of the carrier to correctly aline the larger end of the holders which project beyond the periphery of the carrier relative to the closure disk forming and inserting means and the closure disk securing means. The other holder section is yieldingly urged toward the fixedly mounted holder section to retain a receptacle body therein, and said section being adapted to be moved away from the section fixedly supported on the carrier when the holders are moved by the carrier relative to the position for ejecting the completed receptacles from the holders. Due to stresses set up by the subjecting of receptacle bodies in the holders to the action of the closure disk inserting and securing means the sides of the receptacle body will be caused'to tenaoiously adhere to the wall of the holder section, and to facilitate the ejecting of the formed receptacles from the holders means are provided which are projected through opposite Wall portions of the holder sections as the one section is moved away from the fixed section at the ejecting position of the carrier to engage the receptacles and strip the same from the walls of the holder sections to permit of the ready ejecting of the receptacles from the holder by a stream from a source of pneumatic pressure directed into the receptacles.

Similar characters of reference designate like parts throughout the different views of the drawings. u

' In carrying out the invention there is provided a carrier in the form of a horizontal extending disk 7 having a series ofreceptacle holders, shown as eight in number in the present instance, equidistantly spaced aboutand extending radially of the disk with the outer end projecting beyond the periphery of the disk as shown in Figure 2, wherein certain of the holders are shown diametrically in dot and dash lines. The carrier disk is fixed to a shaft 8 rotatably supported in a sleeve portion 10 extending "from a suitable supporting table (not shown) with a shoulder portion 9 of the shaft engaging the end of the sleeve. The shaft and thereby the holder carrier is intermittently rotated by suitable means, as shown for instance in Letters Patent #1,628,074 issued May 10 1927, to Irving Stanley as the assignor to Sealed Containers Corporation, the assignee of the present application, to successively position the receptacle holders at the stations indicated at a to h respectively, the distance between each staview of a receptacle tion being equal to the distance of each intermittent movement of the carrier disk.

, At station a receptacle body forming means are arranged and when the holders are positioned at said station they receive a receptacle body R from a mandrel M of said means during a period of rest of the rotation of the carrier disk 7 Upon the next intermittent rotation of the carrier disk the holder with the receptacle body therein is moved to position b where no operation upon the receptacle occurs. By the next intermittent rotation of the carrier disk saidholder is movedto station a positioning the end of the receptacle body at the outer end of the holder projecting from the carrier disk in alinement with punch and die mechanism (not shown) to sever and peripherally flange a disk D from a web W, as shown in a conventional manner, and osition the flanged disk D into the end 0 the receptacle body to constitute a closure or bottom disk of the receptacle.

By the two subsequent intermittent movements of the carrier disk the end of the receptacle body with the closure disk inserted therein will be moved to stations 03 and e in alinement with spinning means, shown in a conventional way at S, S to fold inward an end portion of the receptacle body projecting beyond the flange of the disk D over the disk flange at the first spinning means S, and then interfolding the contiguous receptacle portion and the disk flange at the spinning means S. From station 0 the holder is moved to station 7 where no operation is effected, and from said latter station to station 9 where the bottomed receptacle is ejected from the' holder, as indicated at R in dot and dash lines. From station 9 the holder is successively moved to stations h and a,-and at said latter station again receives a receptacle body from the mandrel M of the body forming means.

To facilitate the positioning of the receptacle body into the holders the holders comprise a pair of longitudinal separable sections 11, 12 of semi-circular shape in cross section and conforming to the shape of the body of the receptacle tobe formed, in the present instance of truncated conical form, to securely retain the receptacle body therein, the sections being pivotally connected one with the other ata marginal portion to have movement on an axis extending longitudinally of the holder by a pintle 13 extended through perforated ears 14 pro ecting laterally from a longitudinal edge portion of the section 11, and perforated ears 15 extended laterally from the opposed longitudlnal edge portion of the-section 12 en aged between t e ears 14 with the pintle fixe to the ears 15 by a pin 16. The holders are arranged with the adjustments of the holders on the carrier disk inverted T slots 17 are arranged in the top surface of the carrier disk to extend radlally inward from the periphery to adjacent the center thereof for the engagement of nuts 18 to impinge against the underside of the slot flanges and threaded onto headed bolts 19 extended through the reduced portion of the slots. lhe bolts serve to adjustably secure mounting members in the form of plates 20 for the holders upon the carrier disk, the bolts being extended through perforations in said plates adjacent each corner. To permit of adjustment of the holder mounting plates in adirection circumferentially or laterally of the carrier the reduced portion of the slots 17 are of a width greater than the diameter of the bolts 19 to permit movement of the bolts in a direction laterally of the slots, or in a direction laterally of the axis of the holders.

To effect adjustment of the holders in a direction radially of the disk the nuts are loosened through the turning of the bolts by the heads. To mount the holders on the mounting plates 20 and thereby on the carrierdisk the holder sections 12 are arranged intermediate the side edges with a base member 21 integral with and extending longitudinally of the section and having a plate portion with the opposite longitudinal marginal portions extended laterally of the connecting portion of the base with the holder section and having perforations therein adjacent the corners for the passage of threaded posts 22 threaded into'the plate 20, with the holder section 12 adjustably mounted on the posts by nuts 23 threaded onto the posts abutting the opposite sides of the plate portion of the base 21. By turning the nuts 23 onto or off from the posts the sections 11, 12 are adjusted in a vertical direction or raised or lowered relative to the carrier disk 7. The

sections are normally urged to closed position or into mating relation by springs 35 attached at the ends to pins 36, 37 fixed in and extending from the respective holder sections 11, 12.

To radially position a receptacle body into a holder as it is ejected from the mandrel M of the body forming means at station a, the

holder sections are separated or spread against the action of the springs 35, as the diameter of the sections in closed mating position is suchthat substantial longitudinal movement of the receptacle into the holder is impossible due to the-frictional contact of the receptacle body with the wall of the holder. .To separate the holder sections the section 12 is arranged adjacent the longitudinal edge opposite to the pivotal connection of the sections with a bifurcated ear 24, a lever 25 being pivotally suspended from between the bifurcation legs of the ear to have swinging movement on an axis extending parallel with the longitudinal axis of the holder, which movement is limited in one direction by the lever engaging a projection or stop 26 extended from the base plate 21.

When the sections are in receptacle enclosing position a roller 27 rotatably carried between the legs of a bifurcation of an arm 28 extending from the section 11 engages the top or end of the lever 25 and urges the lever against the stop projection 26, said engagement between the lever 25 and roller 27 is yieldingly maintained by a spring 29, one end of which is attached to a pin 30 extending from the side of the arm 28 and the other end attached to an extension 31 of the pivot of the lever 25. The section 11 is moved away from the section 12 about the pintle 13 by the swinging movement of lever 25 away from the stop projection 26 thereby moving the roller carrying arm 28 in an upward direction due to the The disk is intermittently rotated in a counter clockwise direction and as the lever roller 32 rides up the cam 33 the lever 25 will be swung in a projection 26 forcing the holder section 11 in an upward direction away from holder section 12, and when the roller rides off from the cam, which is subsequent to the engaging of the receptacle body from the mandrel into the holder, the holder section 11 will be again moved into mating relation with holder section 12 with the roller 27 in engagement with the lever under the tension of the springs 29 and 35. I

By the engagement of the flanged disk into the end of the receptacle body in the holder, and the engagement of the spinning means S, S with the receptacle end in the securing of the closure disk in the receptacle body, 1 v

there is imparted a force upon the holder in a direction longitudinally of the holder, Whichlaterally from the movable holder section- 11, and the abutment 40 engaging in the rear of and with the arm 28 of holder section 11. The abutments 38, 39 and 40, 28

in conjunction with the pivot ears 15 on the fixed holder sectiorr 12 engaging with the pivot cars 14 of holder section 11 not only prevent longitudinal displacement of the holder sections one relative to the other but also prevent lateral distortion of the holder sections transversely of the longitudinal axis of the sections due to the forces transmitted to the holder sections through the strains and stresses of the driving torque of the spinning means. The inner faces of the abutments 39, 40 are curved to conform to the curvature of the holder sections to permit of free movement of the section 11 relative to the section 12.

From the spinning means S the holders are successively advanced to stations 7 and g, and as the holders are advanced to the latter station 9 the lever roller 32 rides up a cam 41 similar to the cam 33, extending about the periphery of the carrier disk adjacent station 9, and through said engagement of the lever with the arm roller 27 will move the holder section 11 away from the holder section 12 preparatory to the ejecting of the completed or bottomed receptacle from the holder. However, due to forces exerted on the receptacle body in the holder the body is firmly impinged against the wall of the holder and tenaciously adheres thereto.

- Means are, therefore, provided torelease or 7 shape and extending through an arc of sub-- g a knife edge pivot of a col During the movement of the holder section 11 ;trip the receptacle from the holder sections. This means comprises an arm 42 of arcuate stantially 180 degrees, said arm being pivotally mounted intermediate its end on the pintle 13 approximately midway of the ends of the holder and retained on the pintle between collars 47 47 fixed on the p-intle. One end of the arm extends over and in superposed relation to the holder section 11, and the other and below the section 12. The opposite ends of the arm are bent inward in a direction toward the holder sections forming ears 43, which are adapted tobe extended into open ings 44 in the holder sections midway between the longitudinal edges thereof. The

portion of the arm extending relative to the holder section 12 passes through an opening 45 in the base plate 21.

The arm is normally maintained in position with the cars 43 within the openings 44 with the ends thereof substantially flush with the inner surface of the holder sections when the holder sections are in receptacle enclosing position by an angular stem member 46 fixed at one end in the collar 47 the opposite angle end of the stem slidably engaging a perforation in a lug 48 extended from the arm 42 and arranged below the pivotal mounting of the arm, with ar 49 fixed on the stem engaging the upper surface of the lug 48. The arm 42 is yieldingly maintained in a position of equilibrium with the ears 43 engaging within the holder openings by a spring 50 coiled about the portion of the stem extended below the lug 48 and confined between the undersurface of said lug and a washer 51 retained on the end of the stem.

away from the section 12 the ear 43 engaging in the opening 44 of section 11 will be exor release the receptacle from the holder section 12.

In this position the receptacle within the holder sections is loosely supported between the ears 43 of arm 42 when the receptacle is ejected from the holder by pneumatic pressure directed into the inner and open end of the receptacle y a pipe 53, only a portion of which is shown, fixed on an extension of sleeve 10 to extend in the plane of the longi-.'

tudinal axis of the holder at station 9, the pipe being enclosed within a housing 54 mounted on the carrier disk and arranged with a series of openings 55 adapted to be alined with the longitudinal center of each receptacle holder.

After the ejection of the receptacle from the holder, the holder is moved by the successive movement of the carrier disk to position h where the holder to closed position by the action of the springs 29 and 35 due to the lever roller 32 riding off from the cam 41.

From position it the holder is again positioned at station a, and during the travel thereof to station a the lever roller 32 again rides up the cam 33 thereby moving the holder section 11 away from holder section 12 to permit of the ready engagement of a receptacle body B into the holder. It will be obvious that modifications may be made in construction and arrangement of parts without departing from the scope of the invention, and that portions of the apparatus may be used without others and come within the scope of the invention.
