To all whom it may concern.'.

Be it known that I, FREDE ICK llnen'r, a citizen ol the United States of America, and a resident of the borough of llroo lvh, in the;

'city oi New York,- countv oi" King's, and

cap being formed with an annular head -x terior' to the bottle-lip, the head having a shoulder substantially at right angles to the axis of the cap and a part depending l'roin the shoulder constructed to locl-t against a shoulder on the underside of the lip.

In the attachment of caps of this general? (lQSUI'IptIOD to bottles it is necessary first to.

force the sealing medium withinthe cap int-o intimate contact with the mouth of the hottle by relative niovei'nent in the direction of the hottlo axis two parts of the apparatus for ap 'ilying the cap, one part a machinehead resting against the (lap, and the other part a table supporting the bottle, and, second al'terand while the cap and bottle are so clamped "force that part of the cap which is to e'ieot the locking of the cap toward the bottle axis into engagement with the shoulder or underside ol the bottle-1i; in such apparatus as has been heretofore devised for eTbcting the. closure of such caps on the mouths of bottles, separate instruinent-alities have been required to perform the two abovedefined operations, one instrumentalit f aeting first on the top oil the cap, and the other 'instruincntality following in action and pressing toward the bottle-axis against some portion of the cap which is exterior to the bottle lip, usually by a wedging or camping; or rolling action to positively ioroe inwardly the parts against which (the instrumentality contacts.

.My present invention has been made with cspcoial relerenoe to its applicability in l'-- footing the elosure on a bottle of a cap Wlilt'll has,j "-1 addition to ,tho oharactcristirs above noteil, a bead l'o-r'med on the rap whioh is 0::

terior to and projects in whole or in part beyond the'hottle-lip when laid, on the hottlemi. ath. Such a form of bottle-rap is set forth in United States Lcttcrs-l atent No.

granted to me -ipril ,3, lililil, and, an improvemmit thereon, in eonnertion with which my present invention is illustrated, is set forth in an application for Letters-Patent of the United States entitled caps for bottles exeruted by we concurrently with this application on which Patent No. 796,354 was granted August 1, 1905-. The head has a certain degree of-stihiess or resistance to change of form in order that the objects herein set forth may be properly carried out in the n'zanner described.

In. applying caps of this character one object of my invention is to elleet the locking engagement of the cap and bottle by so making and applying the instrumentalitv for this purpose that the portion of the ie( 1} acts is positively forced downwardly rather than inwardly, and by a rolling action of the head the locking engagement is offected hy a part depending from the shoulder which is a dillerent part of the cap fromthat which is directly operated upon.

Another object of my invention is to eil'ect the movement of the cap relatively to the bottle in the direction of the bottle-axis and the consequent. forcing of the sealing" medium by pressure applied to the shoulder of the head exterior t 'the bottle-lip. The two properl by reason of the proper proportion of lire cap, the head having such stillness that it yields to change of form so that the after the first operation is completed. The two operations (an therefore be performed by the same inst rui'nentality, thereby much simplifying the apparatus.

In the accompanying three sheets of draw ing's which form a part of this application,-

of the rapon the hottle. ,l ig. 4 is a view of into intimate contaet with the bottle-month the chuck from underneath drawn to the same scaie'as the preceding figure. Fig. is a vertical section through a portion of the chuck drawn to a still larger scale showing the relative proportions of the operating parts of the chuck,-the ca before it is ap lied to the bottle, and, in ful and dotted ines, the outline of the mouths and lips of respectively-large and small-mouthed bottles to which the cap can be successfully applied. Fig. 6 is a section drawn to the same scale as the preceding figure showing the cap applied to a bottle of average size. a

For the purpose of illustrating a complete embodiment of my invention a foot-power machine -is shown in Figs. 1 and 2. A column 1 has a forwardly projecting arm :2 which carries a pressure-applying or machine head 3, suitably constructed to act upon the cap, ap ly it to the mouth of the bottle, compress t e sealing disk between the cap and bottle-mouth, and effect a locking engagement between the cap and bottle upon the application of pressure in the direction of the bottle axis a:a: between the pressure-applying head and a table 4 which underlies the bottle in the .axis of the machine. The table surmo'unts a two-part shank, one part 5 of which is a part of the table casting, and the other part 6 of which is threaded or screwed therein. By screwing the one part on the other, the hei ht of the table may be adjusted to suit di erent lengths of bottles. The two-part shank is guided by arms 7 S, which project from the column.

The actuating mechanism consists of a foot-treadle 9 which is fulcrumed at 10 to lugs cast on the underside of the base of the machine. Midway of the treadle is a mortise in which the lower end of a link 11 is pinned. The u per end of this link -is inned to the for ed arm 12 of a bent lever. he fulcrum of this bent lever is a in 13, the ends of which rest on two pillowlocks 14. The pillow-blocks are su ported by springs 15, and lie in two vertica spring-pockets 16 which are cast in the base of the column. The pockets lie on opposite sides of the bent lever and the axis of the machine. The springs are strongly compressed and normally force the pillow-blocks against the tops of the pockets by which they are held under an initial strain when the mechanism is otherwise relaxed. The other arm 17 of the bent lever, also forked, has inncd there to the lower end of a link 18, tie upper end of which is pinned to the lower part of the shank of the table. This arm and link form a tog le whiclris straightened under the table y the depression of the treadle. The springs serve as an elastic abutment for the toggle which yields when the toggle is straightened to allow for slight variations in the height of bottles from the height for which the table may have been adjusted. Depression of the treadle with acap and hottle in place lifts the table and forces the cap and bottle against the ressure-a plying head, and the pressure-app ying hea eflects the closure by the instrumentality which will now be described.

The essential feature of the machine-head which effects the objects of my invention is an annular bearing face 19. This rests against the shoulder a of the head I) of the cap C, the shoulder being substantially at right angles to the axis of the cap. The part of the bearing face which actua ly contacts with the bead is at the corner adjoining the countersunk nortion of the head in which the crown of the cap lies. There is clearance between the crown oi the cap and the bottom of the countersink, and between the side flange of the cap and the sides of the countersink. The latter clearance is a few thousandths of an inch, which is sufficient to allow for the slight irregularities and variations in the size of the caps, but is preferwil rest against the bead quite close to where it s rings from the flange of the cap,

ably not much more, so that the bearing face as I find t at a machine in which the bed is so made, gives a satisfactor closure. The

orizontal, and

contacts is horizontal or nearly so, departing therefrom by less than the angle of friction of the contacting parts with the direction of movements The bearing face consequently presses substantially normally against the shoulder of the bead, and its action is to force the part of the bead against which it contacts in the direction of the bottle-axis, and of itself exert no wedging action, thereby avoiding wear. The action of pressure in the direction of the bottle-axis thus brought to bear on the shoulder of the bead is, first, to forcibly draw the cap down and compress the sealing medium D within the cap into sealing contact with the bottlemouth G, and, second, when the sealing medium has been compressed sufficiently and further compression is sumciently resisted, overcome the stillness .of the bead and roll it downwardly a proximately about its line of juncture with the depending flange of the cap. The wire w contained within the bead, and also the lower mar in of the head,

are thereby carried inward y toward the axis and one or the other or both are thereby brou ht into locking en agement with the shou der 7c of the bottleip. The axial pressure requisite for effecting the locking engagement in this manner is sufilcier t, if continued indefinitely, to pull apart the deending flange of the cap or 5 car off the sad therefrom. Means are therefore provided for limiting the movement of the parts in the direction of the axis of the bottle.

sea-see These means are afforded by the provision in the machine-luau] of a stop-faceQO ezhich is the bottom of the countersink in the chuck at a proper depth so that it i ill come into engagement nith the part of the cap which overlies the bottle-mouth when the rolling of the bead and consequent locking engage-- ment with the shoulder of the bottle-lip has been effected. This limiting action, since it is through the cap and sealing medium, which are quite uniform, against the bottlemouth, will be in proper adjustment irret es.

T he mouth of the machinmhead or chuck which carries the annular bearing face and,

the sides of thecountersunk space and proect ghtly lUfU'thG space. ''hey hold the caps in the chuck preparatory to the operatlon of the machine.
