chines, of which the following is a full, j=

clear, and exact description, reference being had' to the accompanying drawings', orming part of this specification, inwhich- Figure 1 is 'a longitudinal vertical section of a sealing head embodying my invention and showing a bottle neck and cap in entering position; Fig. 2`is saine scale with the cap shown in nearly its sealed position; Fig. 2a is a detail view on a larger scale, illustrating theA action oil-he dies upon a cap; Fig. 3 is a section on the line IIL-III of Fig. 1; Fig. is a perspective view of the die carrier; and Fig. is a perspective view of one of the dies. Fig. (Sis a sectional elevation illustrating generally one means for lifting a bottle to-the action of the capping head.

My invention has relation to sealing heads for bottle cappingmachines, and is designed to provide a novel and etlicient head of this character, especially adaptedffor use with sealing caps having a substantially horizontal corrugated iiange,

into the vertical plane of the skirt of the cap, and the corrugations of the `flange 'forced inwardly u derneath -the locking shoulder of the bottle. y

The invention has more particularrelation to the novel construction and arrangement of 'the dies for eli'eeting this work. f

'The precise nature of my invention will be best understood by reference to the lac,- companying drawings, in ywhich I have shown the preferred' embodiment thereof, and which will now 'be described, 'it'V being premised, however, vthat various" changes may be made in the details ot the constructionand arrangement of thevarious parts without departing from the spirit and scope of my invention as defined Iin the appended claims. A .v In these drawings, the numeral 2 desigwhich, in the downwardly a similarl view on f .natesv 'the' casingroethe P. WETMORE, Ohio, have in Improvement in l' ment of the die.

The die members are seated in a block 5, which is removably fitted within the lower portion 'head to. effect the of the head', .and 4which is formed 'with `aV plurality of radial slots 6 to seat the' dies.

Each die is formedwith an outwardly opening pocket 7 to' seat a spring 8, 'the-innerend of the spring seating against the. inner wall of the pocket, and the outer end seating in a screw plug 9. These screw plugs are threaded into a. sleeve 10, which is threaded into the head and surrounds the die-carrier 5, land has an inwardly extending annular flangell at its lower end, which 'forms a bearing surfaceior the lower faces ofthe dies 4. The die carrier is formedwith the shoulder .at .12,'which is arranged to be engage-d by a stop lip'or projection 13' on'each die Afor the purpose of limiting the movecapable ot'an independent limited radial movement against its spring.

14 is a rod! orl plunger, which extends vertically upward into-the Shelli or casing 2, 4being guided at 15 .at'its'upperenm and having a; surrounding flange 1.16 near vits lower end, which .'normally' seats downwardly against the upper face o fr the die carrier 5. The portion lilab of thisplunger which isbelow the flange 1G extends downthe die cavity.

member may be normally secured in place by a clip or latch device 21. This g'uide member is also cut ai'vay at its upper surface at one side as shown at Q2 to form a space for the operation of a cap feeding device, which may be of any approved character.

24 indicatesa bottle to be capped, and 25 one of the horizontallylianged sealing caps. The operation is as followsz-The caps are successively fed into the position shown in Fig. l by the action of the feeding .de-

vices, and the bottles are then elevated against the caps and the lower end of the plunger 14a. This raises the plunger against the spring 17, and brings the horizontal `flange 26 of the cap, into contactwith the lower' horizontal face of the dies. lt will be noted that each of these dies has a horizontal lovver face and a vertical inner face, and that the tivo faces are connected by the rounded surfaces daf The first contact of the dies with the horizontally extending flange Q6 of the cap is at apoint near the outer edge of such flange as shown in Fig. 2a, thereby preventing any tendency of the dies to shear the flange from the body or skirt of the cap, and

. also giving an effective bending leverage.

As the ca is forced uovv'a rdl1 into these dies l. to the position'shovvn in Fig. 2, the frange is bent or wiped downwardly into substantially the vertical plane of the skirt portion of the v sition the eorrugations naturally close and their upper end portions are forced inwardly underneath the usual locking shoulder on the bottle, thus giving a very secure and effective loclr. Y

Owing to the fact that the bending pressure reo'uircd to maire the seal is almost Wholly in a vertical direction, there is practically an entire absence of any inward pressure against the necks of the bottles of a The dies being made in sections, capable of independent yielding movement, readily adapt themselves to irregularities in the ferm of the bottle noch, and also to variations in the sizes of such nc., o that perfect sea-l is proy duced notvvi' tending such variations or differences. The caps can also be made of relatively thin metal which will readily stretch and adapt itself to these differences and variations. v

For convenience in removing the diebarrier and dies from the headand handling them as one piece, the die carrier may be connected to the slee-ve or bushing lO by means of screws passing upwardly through the inwardly extending flange of the sleeve into the dies carrier, the perforations in the lat-ter for these screws being shown at 27 in Fig. t, andthe screws being shown at 28 in Fig.. 3.

Any suitable or usual means may be employed for lifting the bottles to the action of the capping head. I have indicated in Fig. 6, one such means, consisting of a vertically movable plunger A having a cross head at its lower end, Which is actuated by a rotating cam B.
