Dec. 31, .1935. A. G. ENOCK CAPSULING BOTTLE AND APPARATUS THEREFOR Filed Jan. 18, 1954 Patented Dec. 31, 1935 UNITED CAPSULIN G BOTTLE AND APPARATUS THEREFOR Arthur Guy Enock, Wembley Park, England Application January 18, 1934, Serial No. 707,147 In Great Britain February 2, 1933 1 Claim.

This invention relates to a method of and apparatus for capping or applying capsules to bottles more particularly to such as have a bead round the outer edge of the mouth.

In my application for Patent No. 670,325 filed May 10, 1933, I have described a method and apparatus by which a cap or capsule out in sheet or disc form is fed into position over the bottle mouth, is partly formed thereon and finally is, in situ, shaped to and secured around the bead of the bottle mouth.

The object of this invention is to provide means whereby the caps may be fed to the bottle capas distinct from being fed from a magazine containing a number of cap pieces previously cut to size and shape.

According to the invention the capping machine is constructed with feed rollers to feed forward the material, a punch by which the cappiece is severed from the material, means by which the severed cap-piece is placed in approximately a flat state in position over the bottle mouth and a folding die and crimping appliance such as described in application No. 670,325.

The invention will be fully described with reference to the accompanying drawing:-

Fig. l is an elevation of cutting punch in advance of the capping head.

Fig. 2 is a plan of Fig. 1.

Fig. 3 is an elevation with cutting punch placed concentrically with the capping head.

Figs. 4 and 5 show an alternative form of blank holder.

Referring to Figs. 1 and 2 the apparatus is constructed with a die or punch E adjacent to the capping head K and feed rollers G, G. A transfer arm H with a suction nozzle P and pipe h is mounted adapted to receive the stamped out cap-piece and transfer it to position in the recess is below the capping head above the bottle mouth. The transfer arm H may be operated by a cam H synchronizing with the means round the tension roller B and guide roller C and is fed by the feed rollers G and G to correct position with relation to the cutting dies or'too'ls The blank cap piece is here cut by pedestal of known the tools E and E and while still approximately flat and unformed is deposited on or removed by the suction nozzle P of the transfer arm H. This arm moves until it is under the capping head K and deposits the blank cap piece on to the suction 5 holder J in the capping head K or inthe recess is below the capping head. From this position the blank is formed to shape and attached to the bottle as described in my specification No. 670,325. The feed rollers G and G may also emboss the 0 material as it passes between them or a separate pair of embossing rollers 'D and D may be provided. The scrap material S from which the cap-pieces have been cut is re-wound at spool R.

A modified form' of the transfer arm H is shown 15 in Figs. 4 and 5 constructed with an open or hollow tray L upon which the blank cap-piece is deposited after being cut and moved to a position head K, the bottle mouth passing through the open or hollow tray L as it rises. Alternatively the action of the. transfer arm H and the tray L may deposit the cap on the suction attachment J of the capping head in which case the tray is 25 returned away from the capping head before the bottle rises.

In the construction shown in Fig. 3 the punch and cutting dies Q andQ are placed concentrically round the capping head K which is fitted 30 with a suction nozzle J to retain the cap-piece in position until applied to the bottle mouth. The cutting is preferably performed by the tool Q rising against the edge of the tool Q as the bottle N rises though the tool Q may be depressed si- 35 multaneously with the rising of the bottle N. The material F is fed through as before described from the reel A by the feed rollers G, G into the capping head and is cut in situ over thebottle mouth by the tools Q, Q The severed 40 cap piece adheres to the tools, or to the suction nozzle J placed in the capping head, until removed by the bottle as it rises into the capping head K.

What I claim as my invention and desire to 45 protect by Letters Patent is:-

In a machine. for capping bottles with flat disc shaped caps the combination with the capping head of a punch adjacent thereto to sever cap pieces in succession from a strip of material, a 50 pivoted transfer arm below the punch, a suction nozzle thereon by which the punched disc is held and transferred from the punching head -tothe capping head, a capping plunger in the capping head, and a suction nozzle. centrally disposed 55 within the plunger to receive the disc from the transferring arm and hold it on the bottle mouth during the capping operation.
