Y., assignor to American Sealcone Corporation, New York, N. Y., a corporation of New York Application July 28, 1949, Serial No. 107,196

This invention relates to apparatus for making receptable bodies having one end closed and the opposite end arranged with a ring having an inwardly extending shoulder for supporting a closure in said opposite end of the receptacle bodies.

The apparatus is particularly adapted for forming a tubular receptacle body from a flat blank ofipaper, inserting 'a metal ring having a closure supporting flange in one end of the receptacle body, forming and inserting a flanged paper disk mthe opposite end of the receptacle body to constitute the bottom closure thereof, securing the bottom closure in the receptacle body in two steps, and securing the closure supporting ring in the receptacle body simultaneously with the final step ofsecuring the bottom closure in the receptacle body.

It is an object of the invention to adapt existing apparatus as shown in Patents No. 1,916,981, issued July 4, 1933, and No. 1,917,374, issued July 11, 1933, to Ellis L. Jones, to secure a closure supporting ring in the filling and pouring end of the receptacle. body formed in said machines.

It is another object of the invention to provide .a spinning head to secure the closure supporting ring in the receptacle body adapted to hold the receptacle body against longitudinal movement in a holder therefor during the final spinning of the bottom closure and the spinning of the closure supporting ring in the opposite ends of the receptacle body.

It is a further object of the invention to provide. a spinning head for securing a closure supporting ring'in one end of a receptacle body simultaneously with the final spinning of a bottom closure in the opposite end of the receptacle body without interfering with said final spinning of the bottom closure. 7

Another object of the invention is to operate both spinning heads from the same source of power.

Further objects and advantages of the invention will be disclosed in the detailed description of the invention.

The embodiment of the invention is shown with an apparatus for making paper containers partly shown in Figures 1 and 2 as comprising a table 9 supported in elevated position by legs partly shown at 10 in Figure 2. A tubular body I l is formed from a flat paper blank in the manner shown in the aforementioned Jones patentsand inserted in a holder 12 of a series of tubular holders mounted on a conveyer in the form of a disk I3 secured to a shaft 14 rotatably mountedin the table 9 and intermittently actuated by suitable means disclosed in the Jones patents to present the holders to different predetermined positions or stations.

Looking at Figure 1, the holder 12 at station A receives a receptacle body I i from the body forming mechanism of the apparatus ,shown in the Jones patents. The holders [2 and the receptacle bodies H are of such size and shape that the opposite end portions of the receptacle bodies will extend from the corresponding ends of the holders, as shown at f and f in Figure 3.

During the positioning of a receptacle body H in a holder l2 at station A, the end portion of the receptacle body is engaged with a closuresupporting ring g positioned at the corresponding end of the holder by the lower end of a chute l5 having the upper end connected to a hopper (not shown) for a supply of said rings. The ring g. has laterally extending flanges at the opposite ends, one flange extending inwardly to support a closure member and the other flange extendingv outwardly to engage the edge of the receptacle end portion and be curled or rolled with the y 3 receptacle end portion 1, as hereinafter described.

At station B, a holder [2 presents the end portion 7 of the receptacle body therein to means, indicated in a general way at l6, to form a peripherally flanged disk h from a web w shown in Figure 2, and insert said flanged disk in the receptacle body end portion f. The'mechanism I6 is fully illustrated and described in the aforementioned Jones patents. The flanged disk h constitutes the bottom closure of the receptacle body H.

At station C, the flange of the bottom closure disk h is partially secured to the end portion 1 of the receptacle body by a primary spinning mechanism indicated in a general way at l8 in Figure 1. The primary spinning mechanism 18 is of the same construction and arrangement of parts as the final spinning head for securing the bottom closure disk h in the receptacle end portion I, and description of both is not deemed necessary. The partial securing of the bottom closure disk is shown at i in Figure 3.

At the succeeding station D, the bottom closure disk h is finally secured to the receptacle end. f simultaneously with the securing of the closure supporting ring g to the receptacle body end portion f. The securing of the bottom closure disk h to the receptacle body end portion 1 is accomplished by a spinning mechanism comprising a series of spinning rollers 19 rotatable carried in equidistantly spaced relation to each other by ahead 20 secured on one end of a shaft 2| rotatably and slidably mounted in a standard 22 supported by the table 9. The head 20 is rotated from a suitable source of power shown as an electric motor 23 supported by the table 9 and operatively connected to the shaft 2| by a longitudinally adjustable coupling comprising a head 24 secured to the motor shaft and having a series of openings therethrough for the slidable engagementof pins 25 fixed to and extended from a head 26 secured to the end of the shaft2l opposite the. end secured to the spinning head 20, as shown in Figures 1 and 2. The coupling 24-.-26

permits the spinning head 20 and rollers l9 to be actuated into engagement with the partially secured portion i of the flange of the bottom closuredisk h and the receptacle body end portion I to spin the portion 2' into a tight roll or bead,'as shown. at 7' in Figure 5, and to be actuated out of engagement with the bead 7. This longitudinal adjustment of the spinning rollers 19 and head 20 is accomplished by a rock arm 21 secured at one end to a shaft 28 rotatably supported on the table 9 the opposite end of the arm 21 being bifurcated and the bifurcation leg portions carrying rollers 29 to engage an annular groove 30 in the shaft head 26, whereby the rocking of the shaft 28 will be transmitted to the spinning rollers I9 and head 20 through the arm 21 and shaft 2| without interfering with the rotation of said spinning rollers and head by the motor 23. The shaft 28 is rocked by an arm 31 secured at one end to the shaft 28 and having the opposite end connected by a link 32, as shown in Figure 2, to the actuating means for the conveyer disk [3, as shown in Jones Patent No. 1,916,981, whereby the spinning rollers 19 and head 20 are actuated toward and away from the holder I2 at station D in synchronism with the intermittent actuation of the conveyer disk 13. The parts of the primary spinning mechanism l8 are the same as the corresponding parts hereinbefore described of the final spinning mechanism and are indicated by corresponding primed reference numerals. Said spinning mechanism is reciprocated by the arm 3| through an arm 33 secured at one end to the rock shaft 28' of said spinning mechanism I8 and the opposite end of the arm 33 connected to the arm 3| by an universal joint connection 34, as shownin Figure 1.

Simultaneouslywiththe final spinning operation of securing the bottom closure disk 71. in the receptacle body end portion ,1, the closure supporting ring g is secured in the receptacle body end portion f by a spinning mechanism actuated by and in coordination with the actuation of the final spinning mechanism l9-28. This spinning mechanism comprises an axial support or spindle 35 slidably mounted in a bearing sleeve 36 secured in the lower portion of a plate 31. One end of the support 35 is arranged with a head 38 to abut the outer face of the plate 31 and limit longitudinal or axial movement of the support in a direction from' said plate 31. The opposite end of the support 35 is provided with a head 39 to engage in the closure supporting ring.

g and abut the closure supporting flange there: of to prevent longitudinal movement ofthe. receptacle body II in the holder [2, as fully de.-:. scribed hereinafter. The plate 31 is suspended from one end of a beam 40 supported at the op-. posite end portion by hollow standards or spacers 4| and 42 secured to laterally extending earsof the beam and the table and standard 22by rods.

and nuts screw threaded on the projecting ends of the rods, as shown at 43, in Figures 1 and 2. The support 35 is keyed to the bearing 36, as shown at 45, to prevent the. support from rotating in said bearing but permitting longitudinal movement of the support in the bearing limited in one direction by the head 38. A tubular mem-, ber 46 having an integral annular head or flange 41 at one end is mounted to rotate on and par.- ticipate in the longitudinal movement of. the support 35 by roller bearings. engaged in annular recesses in the opposite ends of the tubular. member 46, as shown at 48 in Figure 3. The end of the tubular member 46 opposite the endhaving the. integral head 41.. is also provided with an annular head or flange. 49 screw threaded in an enlarged bore portion at said end of the tubular member and having two series of equidistantly' spaced

openings

50 and 51 for a purpose tcbe hereinafter described.

The head 41 is arranged to carryequidistantly spaced rollers 52 to roll or spin together. the securing flange of the ring 9 and the end portion J" of the receptacle body II. For this purpose, the head 41 is provided with equidistantlyspaced recesses 53 extending inwardly from the outer periphery of the head and radially of the head for the slidable mounting of carrier blocks 54. Each block has a headed shaft 55 fixed at thefreeend portion in said block with a projecting portion between the block and shaft head rotatably supporting a roller 52. The blocks 54 and their associated rollers 52 are yieldingly urged outwardly from the outer periphery of the head 41 by springs 56 compressed between the blocks 54 and the bottom of the recesses 53.

This outward movement of the blocks 54 and associated rollers 52 is controlled by a hoodmember 51 having a conical or inwardly tapering face 58 and a tubular portion 59 slidably mounted on the tubular member 46 between the

heads

41 and 49 of said tubular member. The conical face 58 of the hood member 51 is engaged by rollers 50 carried in a bifurcated outer end portion of the blocks 54 and forced against said conical face 58;

by the springs '56., The rollers 52 are :mounted on theshafts 55 to extend in theplane of the head 39 andthe rollers 52 are adjusted toward and away, from the head 39 by sliding the hood member 51 on the tubular member 46 to-position different portions of the'conical face 58 relative,

to the rollers 60. The removable mounting-of the head 49 on the tubular member 46 facilitates the mounting of the hood member on the tubular member 46. V

Thissliding movement of the hood member is derived from and coordinated with the adjustment of the spinning rollers l9 and head 20 toward and away from the partially rolled seam 2'. This operation is accomplished by a bifurcated lever arm 6| having rollers 62 extendinginwardly toward each other from the opposedfaces of the leg portions of said lever arm to engage anannular groove 63 inthe tubular portion 59 of the hood member 51. The bifurcated lever arm 6| is secured to an intermediate portion of a shaft 64 rotatably supported at the end portions independing members 65 of a bracket 66 secured to the beam 46, as shown in Figure 6. The shaft 64 is rocked by and in synchronism with the rocking of the shaft 28 of thetfinal spinning: mechanism l9,--28 bya'rock arm '61 secured at the lower end portion to the shaft'28 and having at the upper end' portion amemn extending head 68 arranged with an arcuate slot 69 and ears 19 ex--v arm 61, as indicated at" in Figures 2and 7,

and the upper end portion of the arm 1| is arranged with an opening 'in'horizont'al alinement with the slot 69 for the engagement of a bolt'in said slot and opening, said bolt having a head extending from the outer face of the arm head 69 in horizontal alinement with the ears and secured in the'arms by a nut engaged on the end portion extending from the arm 1|, as indicated at 13 in Figures 1, 2 and '7. The upper end portion of arm 1| is adjustably and yieldingly connected to the arm 61 to participate in the rocking movement of the arm 61 and compensate for any undue resistance to the forward movement of the hood member 51 and rollers 52 to prevent damage to saidparts. plished by a spring 14' compressed between one side of the head of bolt 13 and an abutment screw adjustably mounted in one of the ears 10 and a set screw 16 adjustably mounted in the other car 10' toabut the opposite side of the head of bolt'13, whereby the arm 1| is adjusted to the desired angular position relative to the arm 61 by the adjustment of the screws 15 and1'6, and should the forward "movement o'fv the rollers 52 and hood member 51 toward the receptacle body end I meet with resistance, such as by an extra long receptacle body, the spring 14 will take up said resistance and will shorten the actuatin stroke of the arm 1! without affecting the actuating stroke of the arm 61. The arm 1| is operatively connected to the bifurcated lever arm 6| through a lever arm 11 secured at one end to an extending end portion of the shaft 64 and the opposite end portion of the lever arm 11 pivotally connected to one end of a link 18 having the opposite end pivotally and adjustably mounted in a slot an in the upper free end of the arm 1|, as shown in Figures 2 and '1.

The rollers 52 and hood member 51 are simultaneously rotated about the support in syn- This is accomchronism with the rotation of the spinning rollers I9 and head 29 by operatively connecting the tubular member 46 and hood member 51 to the shaft of motor 23. This-is accomplished by a shaft 8| rotatably supported in bearings 82 suspended from the beam 40 and operatively con-, nected to the motor shaft by a gear 83 secured on the motor shaft and meshing with a gear 84 secured to one end portion of the shaft Bl. The opposite end of the shaft 8| is operatively con: nected to the tubular member 46 and hood meme ber 51 by a'gear 85 secured on the shaft, BI and,

able in the openings 50 in the tubular member.

flange 49 and the end portions slidable in corresponding openings in the tubular portion 59 of the hood member 51 and recesses 9! in the gear 81. p I

To facilitate the transmission of the longitudinal movement of the hood member to the tubular member 46 and support 35, the support 35and tubular member 46 are yieldingly urged away from the gear 81 by springs 92 having an end portion engaged in a, recess 93 in the flange 41 of the tubular member 46 and the opposite end portions engaged in corresponding recesses 94 in the gear, 81 and the intermediate portions of the springs extending through the openings 51 in the flange 49 of the tubular member 46 and corresponding openings 95 in the tubular portion 59 of the hood member 51, as shown in Figure 3. As shown in Figure 6, there are three rods 89 and three springs 92 equidistantly disposed alternately of each other. r V

In the operation of the spinnin mechanism at the station D position of the holders [2, the final spinning head I9, 29 and the ring retaining head 39, rollers 52 and hood member 51 are actuated to the position shownin Figure 3, during the rotation of the conveyer disk I3, by the arm 21 and lever arms BI, 61, whereby the spinning. head I9, 29 is moved to its rearmost position from the receptacleholder l2 and the hood member. 51 is also moved to its rearmost position from the receptacle holder which will move the head 39 androllers 52 in the same direction by the end of the tubular portion 59 abutting the head 49 of the tubular member 46 beforethe hood member reaches its rearmost position and thereby moving the tubular member 46 and the rollers 52 carried by said tubular member 46 and the support 35 which is connected to the tubular member 46 by the ball bearings 48. The rearward movement of the support 95, tubular member 46, rollers 52 and hood member 51 is stopped by the head 49 abutting the gear 81, as shown in Figure 3. During the rearward movement of the hood member 51 prior to the abutment between the tubular portion 59 and tubular member head 49, the conical face 56 is actuated to a position wherein the rollers 60 are engaging the portion of largest diameter of said face whereby the rollers 52 are permitted to assume their expanded position under the force of the springs 56, as shown in Figures 3 and 4.

After the holder I2 is positioned between the head I9, 29 and hood member 51 are-moved to-' ward the positioned-holder I2, and during said movement, the head 39 will engage the closure supporting flange of the ring g while the rollers 52. are still in their expanded position, as shown in Figure 4. The'forward' movement of the support 35 and its associated head 39 is caused by the springs 92 and is arrested by the head 38 abutting the plate 31. Due to the position of the hood member 67 at this point in its forward movement, the rollers 52 are still in expanded position, as shown in Figure 4. The engagement of -the head 39 with the ring 9 will firmly seat the ring in the receptacle body end portion f and firmly retain the receptacle body I l in the holder l2- against longitudinal displacement due to the present'use of the holder and receptacle of truncated shape; a I a L he continued forward movements of the spinning heads i9, 20 and hood member 57 will position the spinning head I9, 20 and the rollers 52 .intoengagement with the partially formedrolI i and the receptacle engaging flange of the ring 9 and the receptacle end I, whereby the final rolled seam 7' is formed and the receptacle end portion ,f and receptacle engaging flange of the ring g are rolledtogether to secure the bottom disk It and the ring 9 in the respective end portions of the receptacle body, as shown in Figure 5. In the Figure 4 position of the spinning head for the ring g, the rollers =52 are positioned in'vertical alinem'ent with the receptacle engaging flange of the ring g asthe axial or longitudinal travel of the support 35 and the tubular member 46 carrying the rollers 52 is in unison, and the continued forwardmovement of the hood member 51 will position the portion of smallest diameter of the conical face 58 in engagement with the rollers 60 so that the spinning rollers 52 are actuated to full contracted position into spinning engagement with the ring 5/ and receptacle body end portion 9". 7

During the movements of the spinning heads 1-9, 20, the rollers 52 and hood member 51, said elements are continuously rotated, so that the engagement of the head I9, 20 and rollers 52 with the partially formed roll 2' and ring 9 will effect therol-l-ing' or crimping of said roll 2' and ring 9.

After the spinning operation has been completed retrograde movement is imparted to the spinning mechanisms, as shown in Figure 3, whereby the conveyer disk 13 is free to be actuated to move the holder I2 having a completed receptacle 'body therein from station D.

- At station the completed receptacle body is eiec'tedfrom the holder l2 by any suitable means, such as a blast of air delivered to the open end or thelreceptacle body by apipfili connected in communication to a source of air, such as acompressor, as showntin Jones Patent No; 1,916,981.

Having thus described my invention, I. claim:
