"MACHINE FOR FORMING BEADED CAN BODIES.

Application filed July so,

To all whom it. may concern:

Be it known that 1, PETER Know, a citi-- zen of the United States, residing in the borough of Brooklyn, county of Kings, city and State of New York, have invented certain new and useful Improvements in Ma chines for Forming Beaded Can Bodies, of which the following is a specification.

This invention relates to machines or devices for forming can bodies, tubes, or the like, especially beaded can bodies, tubes, or the like.

The invention provides a machine or a device especially suitable for can bodies or tubes of small diameter, and provides a horn wherein the construction is simple and strong, when made in small dimensions. The horn or device is especially advantageous as a part of a machine or device for forming beads, ribs, or the like, on can bodies or tubes of small diameter.

The invention further provides an advantageous .combination of parts of a forming horn or mechanism, and of a beading or like horn or mechanism.

An embodiment of the invention is illustrated in the accompanying drawings, wherein Figure 1 is a longitudinal sectional view of a horn of a can body forming and beading machine, together with sufficient of the associated parts to illustrate the construction;

Figure 2 is a view generally similar to' that in Figure 1, showing the parts in a difi'erent position;

Figure 3 is a detailed view, in elevation, of the group of segments forming part of the beading device or mechanism;

Figure 4 is an end view, from the right;

Figures 5, 6 and 7 are, respectively, sectional views, on the lines V-'V, and VII-VII, Figure 2; and

Figure 8 is an end view of a body forming and-beading machine, showing certain parts used in conjunction with the horn. at the beading station.

7 Referring to said drawings, A designates the horn as a whole, which may be, as here shown, a horn adapted to support a can body or tube in a plurality of working positions. In the position -*marked seaming position, the ends of, a blank are wrappeda round the horn'by a suitable folding or wrapping mechanism (not shown), and the 1920. Serial No. 400,201.

lapped and usually interlocked edges bumped or pressed together, all of which is well known in the art. In the position marked beading position, the tubular can body may be formed with a beadxor circular rib, adaptedto stiffen the end of the can and form a shoulder for limiting a cap fitted thereon, when said body is completed in the form of a can or body, as, for example, a snuff box. B indicates a bracket or support for the horn, and C a slide for actuating certain parts of the horn mechanism, as hereinafter more fully explained. The slide C is conveniently guided on the bracket B, and is re ciprocated by any suitable mechanism (not shown).

E designates a reciprocatory feed bar,

having fingers e thereon, adapted to inter-' rlpittently advance bodies or tubes along the The horn preferably comprises a tubular sleeve 10, attached, in suitable manner, to the bracket B.

Hinged upon the sleevelO, as indicated at 12, preferably at or near the end of said sleeve, there are a plurality of segments 15, conforming, as a, whole, to the contour of the tube or body on the horn.

The hinge is preferably formed by a rib 17 on the inner side of the several scents fitting into a groove 18 in the sleeve 10. A spring, preferably a circular or spiral spring 20, encircles the segments 15, and holds the segments in hinged relation to the sleeve 10. A groove 22 in the segments is preferably provided for receiving the spring 20. The segments are preferably drawn together or collapsed by a spring, preferably a circular spiral spring 25, encirc-lin the segments, and preferably fitting 1n a groove 26. a I 4 Suitable means are provided for spreading or swinging outwardly the said segments around the hinge 12, said means being preferably a wedge 30, conveniently fitted upon a rod 32, passing through the sleeve 10, and through the circle or ring of segments 15.

When themachine or device is to be used for beading, means are provided for pressing or confining a can body or tube on the horn, in the vicinity of the segments 15, that is, at the beading position. This means is conveniently in the form of a plurality of radially movable segments or jaws 4C0, slidable in a bracket ring 42, and pressed, in-

ward by means of a cam ring 44, having cam surfaces adapted to contact with rolls 46 on the several jaws ,40. Springs 47 may serve for drawing the jaws away from the horn, when this is permitted by the position on the segments 15, and a groove 51 in the aws.

At the seaming position, the sleeve 10 is conveniently formed with a block or expander piece 55, and means are provided for moving the saidpiece 55 in and out, to expand and collapse the horn at said position. These means are conveniently a plurality of complemental inclines 56, 57, these being conveniently formed directly upon the piece 55, and upon the rod 32, respectively. prings 58 in recesses 59, attached to the piece 55 and to the sleeve 10, serve to draw in the piece 55, so as to collapse the horn when this is permitted by the inclines 56, 57.

Operation.

The sheet metal or other blank is fed or placed over or under the horn in the seaming position (according to the position of the bumper and the design of the machine), and is wrapped around the horn in said position, by well known means( The blank is usually formed with hooked edges, which hooked edges are lapped by the folding means. The expander slide C is thereupon actuated to draw the rod 32 to the left, causing the inclines 56, 57 to press the expander piece 55 outward, thereby expanding or enlarging the tube or can body wrapped around the horn, so as to drawthe hooks .together. Complemental inclines 60 and 61, on the expander slide C, and the rod 32, serve for imparting this movement to the rod 32. When the expander piece 55 has thus acted to draw together the hooked edges of the body, the bumper presses the hooks together, so as. to from a seam. The expander slide retracts, whereupon the rod 32 is pressed to the right, this being preferably accomplished by a spring 65, encircling the end of the rod 32, opposite the wedge 30, said. spring conveniently bearing,

' at one end, against an abutment 66, secured to the bracket B conveniently by bolts 67, the opposite end of the spring bearing against a shoulder 68 on the rod 32.

After the rod 32 has moved to the right, the springs 58, serve to draw in the expander piece 55. The 'feed finger e thereupon advances the can body or tube, either, directly or by way of one or more idle positions, to

iasaeca the beading position. In the beading position, when the rod 32 is pushed to theleft by the expander slide C, the wedge 30 acts to spread the ring of segments 15, which rock or swing on the hinge 12, thereupon bringing the segments against the inner side of the can body or tube. At the same time,

the jaws 40 are pressed in against the can space around the horn is free and the horn i has no peripheral projections exceedingthe diameter of the tube or can body to be formed and beaded thereon, the can bodyor tube therefore having noimpediment to continuous movement in one direction from its position of seaming to its point of discharge from the horn.

When the rod 32 is returned, or moved to the ri ht, by the spring 65, the wedge 30 allows t e spring 25 to draw together or collapse the segments, and aws 40 are conveniently, at the same time, drawn away from the can body by means of the action of the cam ring 44 and the s rings 47. Thereupon, the beaded can bo y is ejected from the horn by a succeeding can body acted upon by a finger on the feed bar E.

Where the beading operation is performed on a device for forming the tubes or can bodies, it is conveniently combined with the seaming horn, as here shown. The mechanism at the beading position, however, can be used separately from the other parts of the mechanism, and the horn at the beading position may have application in machines for performing other operations than beading.

The invention may receive other embodiments and applications than that herein spcifically illustrated and described.
