Renewed February 19, 1931..

The machine provided by the present invention has for its purpose the assembly of separate collar members within can bodies t0 produce a construction in which a side tearing strip may be employed to open the container and the portion of the can removed by tearing away said strip may be employed as a temporary closure.

' provision of an efficient and rapidl operating machine for the purpose re erred to above, which is wholly automatic in action and which performs the assemblingy operation without the necessity of manual handling by attendants of the parts to be assembled.

Another obj ect of the invention is the provision of means whereby the machine may be adapted for operating upon cans of dilferent height.

It is also an object of my invention to provide a can body and collar assembling machine which involves a minimum number of operating parts and which will be unlikely to require frequent stoppage for attention or repa1r.

Another object is the provision of a machine of this character which iscontinuous in Y operation and in which the can bodies-are rounded up, or trued, and the collars inserted therein while the feeding devices continue to move said parts throu h the machine,- with consequent hlgh speed o? operation-if Numerous other objects and advantages of the invention will be apparent as it is better understood from the following description, which, taken in eonnectionwith the ac- 'companying drawings, discloses a preferred embodiment thereof. I

' Referring to the drawings,

Figure 1 1s a side elevation of the machine, certain parts being shown in section for the sake of better illustration;

`ing plate 42 and Fig. 2 is a plan view, partially broken away to disclose certain features ofconstruction;

Fig. 3 is a detail view of the adjusting yoke whereby the machine is adapted to operate upon cans of diil'erent height, said view being taken substantially on the section line 3-3 in Fig. 2;

Fig. 4 is a section taken substantially on the line 4-4 in Fig. 1; and

Fig. 5 is a section taken substantially on the line 5--5 of Fig. 1.

The machine is supported upon a frame, comprising a bed 21,

legs

22 and 23 and upward extensions 24 and 25, a top plate 26' being secured at its opposite ends to upper extremities of said extensions. Said plate is widened at the center and is provided with an opening 27 through which the can bodies and collar members, indicated, respectively, by the reference characters 28 and 29, are adapted to be fed. A body chute is formed by means of retaining

plates

31 and 32 and inwardly extending

guides

33 and 34,- said chute extending from a suitable point of delivery through the plate 26 and being adapted to direct the can bodies into the pockets of spaced

turret members

35 and 36. The retaining plate 31 is held in place by means of an adjusting block 37, which is held to the top plate 26 by means of screws 38 and is secured to said retaining plate 31 by means of screws 39. The

guides

33 and 34 are secured to the

retaining plates

31 and 32 by means of cap screws. 41.

A delivery chute for the collar members is provided adjacent the can body chute and is formed by the retaining plate 32, a retainguide 43. An adjusting block 44. corresponding to the block 37, is employed to hold the retaining member 42 in desired position.

,A turret 45 is provided adjacent the turret member 36 and is adapted to receive and rotate the collar bands 29 in axial alignment with the can bodies 28. Said turret members Y ends of the machine. The can bodies 28 and collar bands 29 having delivered into their respective feeding chutes, fall by gravity into the turrets just described, being received at a station A at which they are arranged in axial alignment. The shaft 46 is continuously rotated by means of a large gear 49, mounted on one end thereof and meshing with a pinion 51 on a short shaft 52, which latter has a bearing 53 depending from the under side of the frame bed 21 and a bearing 54 integral with the end of said bed, said shaft being driven from any suitable source of power by a belt taking over a pulley 55 carried on the outer end thereof. Rotation of the turrets, in counter-clockwise direction, brings the can bodies and collar members to a station indicated in Figs. 4 and 5 by the reference character B and at this point, the can body is rounded up, or trued, by means of a turret 56 having pockets 57 cooperating with pockets 58 of the turret member 36 to bring the upper part of the can body to true circular form prior to the insertion of the collar member 29 therein. The collar is also accurately shaped by the turret 56 cooperating with the collar turret 45, it being noted that said first-mentioned turret is of such -width as to engage both the can body and collar and is of slightly different diameter at 4 spect to the shaft 46 and carries, on its outer end, a gear 65 which meshes with a4 gear 66 on said shaft 46, the turret 56 being thus rotated in timed relationship with the

turret members

35 and 36.

A can body and collar member having arrived at the station B, they are assembled by mechanism to be now described. Chucks 67, corresponding in number to the pockets of the

turret members

35 and 36 and the turret 45, are carried on sliding shafts 68 having bearings in a carrier member 69 keyed to the main shaft 46. Each chuck`67 is formed with a tapered outer face 71 and an annular shoulder 72, being thus adapted to enter within a collar band 29 and to move the same inwardly to a predetermined position within a can body 28. The chuck is reciprocated in desired timed relationship to the rotation of the turrets by means of' a cam 73, bolted at 74 to the upright 25 and `being provided with a cam groove 75 operating upon a cam following roller 7 6, which is mounted upon a stud 77, secured in a yoke 7 8 formed at the rear end of the shaft 68. By this construction, it will be obvious that the chucks 67 are reciprocated periodically as they are rotated in axial alignment with the can body and collar turrets upon the shaft 46. In this manner, the collars are inserted, this action'takin place 'ust after the body has been rounde up at t e station B and during the time that it is moving between said station B and a station C, .indicated in Figs. 4 and 5. It will be noted that the retaining plate 32 extends downwardly between the can body and collar at the station A, as indicated in Figs. 1 and 5, but is cut away beyond the station A, so that when the parts arrive at the station B, the collar may be inserted.

A feature of my invention is the outward flangin of the end of the can body at which the colar is to be inserted, as indicated in Fig. 1. This Hanging is utilized to facilitate the ready and accurate insertion of the collar, and thereafter does or may constitute a double seaming flange when the can is closed in the usual manner of closing sanitary cans. The flanging of the can body may be produced before the cans are fed into the collar-inserting machine, or may be produced at any convenient time.

Adjacent the turret member 35, I provide a large disk 79, which is formed with a hub 81 slidably mounted upon the shaft 46 by means of a feathered connection clearly illustrated in Fig. l. Said disk is of sufficient diameter to vengage the bottoms of all of the cans in the

turret members

35 and 36 and holds said cans against endwise movement as the collar bands are being inserted. At the end of the hub 81, there is provided a recessed collar 82, shown in detail in Fig. 3. A yoke 83, secured to an adjusting bar 84, fits into the recessed collar 82, said adjusting bar 84 being formed with a slot 85 through which extend studs oy which the bai is clamped to an extension of the turret 24. By means of this slotted connection, the disk 79 may be moved along the shaft 46 to vary the distance between it and the chucks 67 to accommodate cans of different height.

The forward stroke of the chuck 67 is completed and the chuck is withdrawn before the can body reaches the station C, it being understood that the length of the stroke is governed by the formation of the cam groove 75 and is calculated to arrange the collar at such position within the can body that itwill be opposite a tearing strip set ofi by score lines in the latter, which preferably are located a short distance below the top. The chuck having been withdrawn, the assembled cans are discharged from the machine through an inclined run-way 88 mounted upon a bracket 89 supported from the bed 21. A horizontal bar 91 is secured to a yoke 92 extending upwardly from said bed 21 and is turned upwardly at its inner end, as indicated at 93. Said bar is adapted to contact with the cans to remove them from the turret pockets at the discharging station C.

It is thought that the invention and many ,of its attendant advantages will be underiso will be apparent thatvarious changes may be made in the form, construction and arrangement of the parts without departing from the spirit and scope of the invention,

or sacrificing all of its material advantages,
