Claims.

The invention relates generally to can making machinery and more particularly to container and end closure assembling machines of the nature disclosed in the co-pending application for U. S. Letters Patent filed by Otto A. Schmitt on Nov. 10, 1939, Serial No. 303,991, and it primarily seeks to provide a novel seaming head structure for use in a machine of this character and a novel mounting therefor. This application is a division of the previously co-pending application for U. S. Letters Patent filed by Alfred L. Kronquest and Otto A. Schmitt on Nov. 27, 1939, Serial No. 306,366 and entitled Square can seaming head, now Patent 2,271,153, issued January 27, 1942.

In the can and end closure assembling machine disclosed in the co-pending application for U. S. Letters Patent above referred to, the can bodies and end closures are individually fed to a turret which is indexed about a horizontal axis, and means are provided on and in cooperative relation to the turret for presenting the can bodies and end closures in loosely assembled relation at a seaming station at which the end closures are seam-secured upon the can bodies. pose of the present invention to provide a novel arrangement of seaming head disposed in cooperative relation to the turret and on a horizontal axis, and a novel mounting for said head which will enable it to be readily swung away from the turret from its operative position to an ineffec- 't-ive position so as to facilitate servicing or inspection of the turret or the seaming head parts.

An object of the invention is to provide a seaming head of the character stated which is swin able away from the turret about a vertical axis, and novel driving connections for the operating parts of the head which will not be disrupted by movement of the head about its pivotal mounting.

Another object of the invention is to provide novel means other than the pivotal mounting of the head for supporting the weight of the head while it is being swung into or out of its cooperative relation with the turret.

Another object of the invention is to provide a mounting of the character stated for a seaming head including a reciprocable knockout pad, means for actuating the knockout pad, and novel quick detachable means in the driving connections which may be readily disconnected to permit the swinging away of the seaming head and which can be just as readily again connected to complete the knockout pad driving connections It is the purwhen the head has been returned to its cooperative relation with the turret.

With the above and other objects in view which will more fully appear, the nature of the invention will be more clearly understood by following the description, the appended claims, and the several views illustrated in the accompanying drawings.

In the drawings: I 3

Figure v1 is a vertical longitudinal section through a container assembling machine with the invention embodied thereon.

Figure 2 is a fragmentary vertical longitudinal section taken through the axis about which the seaming head is pivotally mounted.

Figure 3 is a detail vertical cross section taken on the line 3-3 on Figure 2.

In the container assembling machine hereinbefore referred to and in which the seaming head herein disclosed is intended for use, there is included a frame base 5 and a frame structure 6 arising therefrom and including a shelf 1 and a vertically disposed bearing sleeve 8.

A main power driven shaft 9 is horizontally disposed in suitable bearings in the frame, and a pocketed turret I0 is secured upon one end of a shaft ll rotatably mounted in a horizontal bearing I2 on the machine frame and equipped at its other end with a disk Hi from which indexing rollers project in equidistantly spaced relation for being engaged by an indexing cam I4 which serves to impart step-by-step rotation to the turret for presenting the pockets thereof at the various stations provided in the machine. The cam I 4 is mounted on the upper end of a shaft l5 supported in a vertical bearing It on the machine frame and driven by a gear couple I! from a shaft 18 vertically supported in bearings IS. in the frame and in turn driven by a worm gear couple 20 from the shaft 9.

Loosely assembled container bodyend closure elements generally designated 2|, when presented at the securing or seaming station at the .bottom of the turret as illustrated in Figure 1 of the drawings, are engaged by a chucking pad 22 and are moved thereby from the position illustrated in Figure 1 toward the right for the purpose of engaging the container with the chuck of the seaming mechanism so that the end closurecan be seam-secured to the container body in the manor hereinafter described. The chucking pad 22 is adjustably mounted on a slide head 23 reciprocably supported on the frame and having roller connection as at 24 with a grooved plate cam 25 secured upon the upper end of the shaft l8 and through the medium of which the desired reciprocation is imparted to the pad 22.

The seaming head proper, the mounting of which comprises the main subject matter of the present invention, includes upper and lower casing sections 26 and 2? including laterally extended housing portions respectively designated 26 and 29, and these sections 26, and 21, 29 are flange-secured together as at The sections 26 and 21 thus secured form a large open-ended bell portion 3| in which the seaming mechanism proper operates.

A part of the upper portion of the bell 3% is hinge-mounted as at 32 so that it can be swung upwardly to facilitate access to the interior of the bell and the mechanism therein.

A pivot sleeve or standard 63 depends from the lower head section 2?, 2S, and it will be observed by reference to Figures 1 and 3 of the drawings that the axis of this sleeve is disposed to one sideof the axis of the bell portion 3i of the seaming head housing. The housing sections 26, 28 and 21, 29 together provide a bearing hub portion 34 and a bearing hub portion 35 disposed side by side. The pivot standard 33 is pivotally mounted in the bearing sleeve 8 formed on the machine frame, and the weight of the seaming head is supported in this bearing on an antifriction bearing equipment 36 interposed between the upper end of the bearing sleeve and the opposed portion of said housing.

By reason of the provision of the pivot standard and sleeve bearing equipments 33, 8, it is possible to swing the seaming head housing about the axis of 'the bearing standard in order to move the seaming head into and out of cooperative relation with the machine turret so as to facilitate inspection and adjustment of the parts of the seaming mechanism. In order to suitably support the seaming head during swinging thereof between operative and inoperative positions and for avoiding the setting up of twisting strains in the seaming mechanisms in the head, there is provided a supporting lug 3'1 on the lower head section 21 adapted to be supported upon and ride over an arcuate track at extending upwardly from the frame shelf portion 1. A forked lug 3?! also projects from the lower housing section and is engageable by a quick detachable pivot screw 40 supported on the machine frame and which may be utilized to secure the seaming head in the operative relation with the turret illustrated in Figure 1 of the drawings.

It will be observed by reference to Figure 2 of the drawings that a shaft member 5-! is affixed to the hub 35, and a sleeve 42 is freely rotatable about this shaft within the hub. The sleeve car-- ries a spur gear 43, a slightly larger spur gear 44 and a bevel gear 45. Rotation is imparted to the bevel gear 45 and the sleeve to which it is affixed by a bevel gear 46 affixed upon the upper end of a shaft 4! rotatable in bearings 53 in the standard 33 and which carries a bevel gear 49 at its lower end to which rotation is imparted from a bevel gear 59 secured upon the main drive shaft 9.

The particular seam forming equipments included in the head disclosed in parent case Serial No. 306,366 hereinbefore referred to are particularly adapted to the seaming of square or oblong cans. The particular form of these seaming equipments forms no part of the present invention and it is to be understood that these equipments may be variously formed within the scope of the present invention which relates particularly to the mounting of the seaming head. The

seaming equipments are herein generally desig nated 52 and insofar as the present disclosure is concerned, it will suffice to refer to these equip- 5 ments as including a stationary chuck 52, a reciprocable knockout pad a3 and a knockout rod 5 3 for actuating the same, a rotor 55 for carrying the seaming levers, and a rotor 55 for imparting rotation to the cams or other devices for actuating the levers. The rotor 55 has a driving gear 51 affixed thereto and the rotor 56 has a driving gear 53 affixed thereto.

It will be apparent by reference to the drawings that the gears 51 and 5B affixed to the rotors 55 and respectively mesh with and have rotation imparted thereto from the spur gears and d ll respectively which have been hereinbefore referred to as forming a part of the seaming mechanism driving connections.

The knockout rod extended beyond the seaming head indicated in Figure 1 and is connected at enterded end with the upper end lever his pivoted intermediate its ends,

at on a bracket di secured to the seaming i". At its lower end the lever 59 is co a quick. detachable connection 62 pivoted to a thrust member 64 shut-role in bearings 65 provided therein the machine frame. The thrust member res a roller which engages a suitably plate cam ti which is rotatnbefore referred to. 6'; is so shaped, and the o timed, that the knockout on which it is carried roper time in each seam- .acing the seamed cono -ious by reference to the drawings moving the quick detachable securing cm engagement with the forked'lug sea (1g can be swung about its'p'ivotal mounting whenever it is desirable'to remove i head from the cooperative relation with the turret illustrated in Figure 1 of the drawings the purpose of rendering the mechanisms no. in housing or those mounted d associated. with the turret accessible for nent or replacement and the like. This 50 dsplacez ent of the head is greatly facilitated by the o center position of the pivot axis, and the y of the mechanisms within the a .dditionally facilitated by the hinge mooning til of the upper portion of the housing. Because of the nature of the driving connection between the power shaft 9 and the seaming mechanisms within the head, swinging of the about its pivotai mounting can be effected without disrupting these driving connection or their ynchronized relation to the other mecha nisms of the machine. It will be obvious, however, that before the seaming head can be swung cm the turret in the manner above stated, the quick detachable connection 52 forming a part of the kneels-out pad operating devices must released.

it will be apparent also that when the eaming head either out of or into its cooperative relation with the turret It, the weight of the head is supported by the supporting track can ments thereby to relieve the pivotal moun g of the strain and bending tendency of this ofi-center weight.

It is to be understood, of course, that the details of structure and arrangement of parts may 22,337,999 be variously changed and modified without departing from thespirit and scope of the invention. We claim:
