APPARATUS FOR SEALING BOTTLES.

Specification 0 Letters Patent. Application filed August 19,1909. Serial No. 513,564.

Patented Dec. 30, 1913.

To all 'who/mv it may concern Be it knoun that we, BENJAMIN ADRIANCE and Anios Cnnrnsorr, citizens of the United States, residing in Brooklyn, borough of Brooklyn, and State of New York, have invented a. certain new und useful Improvement in Apparatus for Sealing Bottles; and we do hereby declare the following -to b e a full, clear, and exact description of the invention, such as will enable others skillederation.

The primary object of our invention is to construct the part of such apparatus referred to, and commonly known as the sealing-head, with n view to reduce to the minimum the percentage of breakage or fracture of bottles by the sealing-head during the :1t-

tnching operation, and to simplify and chenpen the construction, while retaining the mechanism positive and reliable in operation :nd adapted to release each bottle without undue resistance when the cap has been established in interlocked and sealing relation with the bott-le and is cleared or freed from the sealing-head.

It iswvell-known that there is a very considerable lack of conformity in bottles, par ticul. rly with respect to their cross sec tionn contours at their locking shoulders. In consequence, in lieu of employing in the sealing-head n cap-contracting throat or throat-pieu.` every portion of which bears a rigid relation to everj.y other portion, vnrious types oit sectional throats have been proposed. Such sectional throats are either ot the kind where each part thereof is independently cushioned by a spring or the like` in which ense, if an ideal condition of uniform resistance by all parts of the cushioning medium ever exists, such sooner or later fails in the constant use of the sealinghead; or. they are of the kind where the parts, perhaps initially independently cushioned by springs or the like, .find ultimate liaekingduring the interlocking operation against some support every part of which is rigid with respect to every other part, so that the sealing-head, so far as adapting itself to or' conforming with irregularities in bottle-heads is concerned, is substantially as inelteetive as the kind sought to beim'- proved upon. Both kinds, moreover, involi-e a multiplicity of parts andthe undesirable incidents thereof, and they require more or less frequenty attention to maintain i.

them in proper working order.

Our invention is to be distinguished from expcdien'ts heretofore proposed, by, und it consists in, a sealing-head having its throatportion, or at least the ,inner surface part thereof, substantially non-expansible yet flexible. Being flexible, it is self-conforming to the cross-sectional shape-of bottlehends presented to it, and being substantially non-exparnsible it resists the-expand' ing influence of the cap and causes the portions ot the latter controlled thereby to move into the desired interlocking. engagement with the bottle-shoulder. Preferably said tlntmt-portion has an interior form like that ot :t truncated cone, whereby (in applying certain types of closures, for instance'of the common crown kind) 'the better to e'ect the interlocking of the cap with the bottlehead und make it adapted to receive bottlehends varying more or less in circumferential dimension, a yield, to afford com ensa- -tion for such variations in bottle-hea s, be-

iurr permitted in the mechanism whereby tlnhottie and sealing-head are brought into operative juxtaposition.

We have illustrated our invention fully and clearly in the accompanying drawings, wherein the preferred form thereof is shown, Figure l being a view in side elevation, partly in section, of a bottle-sealing machine having our improved sealing-head as a, part thereof; Fig. 2 is a View showing the sealing-head, a ca-p, a cap-supporting means and n bottle partly in section .and partly in elevation, the parts being in the position occupied thereby at the outset of the Sealing operation; Fig. 3 is a. View substantially similar to Fig. 2 but showing the parts during,r the interlocking stage of the operation; Fig. 4- is n perspective view of the thr0atpiece m of the sealing head; and, Figs. 5 and 6 arehorizontal sectional v iews on the lines .oJ- mand 1/-y, respectively, of lfigs. 2

and 3, F ig.A 6 showing how the part will conform `to an irregularly shaped bottle The sealing machine comprises the. frame a,the sealing-head and the bottle-elevat-- i against downward movement by the stop e,

a plunger f frietionall sustaining the support d, a rotating sha t g carrying a crank h. and a link h pivotally connecting the plunger 'and crank. y

Referring, now, to thersealing-head: i is a tubular stern which may be secured in the frame a by the set-screw jfits upper end is internally threaded and its lower end has the "externally threaded flange lo. Against its lower end is secured the socket Z, the same havin an external shoulder m engaglng the internal shoulder a of a ring o which is screwed onto the flange of the sleeve and thus holds the socket in place;

a dowel-pin pjmay be introduced into parts lc and l to prevent the latter from turning.

An internal rabbet is formed in the upper part of the socket and therein is fitted an annular disk r, held rigidly between the sleeve and the socket l. Said disk acts to Vguide theplunger s, having a shoulder t at its upper end which limits its downward movement by impinging against the disk, the lunger being normally forced downwardly by a spiral spring u coiled in the sleeve between the plunger and a plug Iv screwed into the upper threaded end of the sleeve. The lower or mouth end of, the socket is formed with an internal `shoulder fw, and between said shoulder and the disk 1, in surrounding relation to the plunger s in the rest position of the latter, interposed the throatpiece cc, the same fitting fairly snugly' between said shoulder and disk. Said throat-piece, in the adaptation shown, is a hollow truncated cone of metal adapted to yield to internally applied influences tending to extend it in any chord or radius thereof but to resist any appreciable tendency to extend circumferentially due to such influences. At its lower end it is formed withl a circumferential rib y and at this, its greatest, diameter, it is somewhat smaller than the cavity 2 of the socket; its saidirib serves principally as a reinforce ment.

A is the'cap, the same being shown as of the conventional crown type, and B the.

bottle; C is the usual support on which the cap lrests until the 'rising bottle brings it against the plunger s.

The operation of sealing a bottle in the use of the improved sealing-liead proceeds substantially as follows: The bottle having been placed on the elevating means and thereby raised, its head engages the cap A. and in raising the latter forces it up into the. conc .'11, the plunger s, under the influence of its spring'fzaholding the cap"meantime squarely on the bottlehead and preventing it from tilting in the latter (due to possible irregularities in` the cap) until itl comes properly within thecontracting inthuence` of the cone. As the'cap is forced up in to the cone, the latter effects a contraction of, the flaring edge-part of the cap, such contract-ion ultimately resulting in thylower or inner corrugations of the ca being 'forced inwardly under, and into loc (ing engagement with, the shoulder B on the bottle. QAlthough the circumferential dimensions of bottles at their shoulders B may vary, or successive bottles have varyz ing heights, such discrepancies are taken-4 care of, to the end that the caps .are unifcrmlyacted upon by the cone, by the yield. afforded in the elevating mechanism). Whatever the cross-sectional shape of the bottle-head at the shoulder B', the cone will conform or adjust itself thereto,"'and.l at the same time, being substantiallynon-expansible, it will com ress the 'cap-Harige posi- A tively under, an into locking Contact with, the shoulder on thezbottle. This` is illus? trated in Figs. 5 and 6. In Fig-5, the cone a'c appears as circular (which is its normal shape, in the preferred form, any alter- I ation of its shape being permitted by .its being somewhat elastic) in'= Fig, 6, the cone has assumed an oval shape, this beingilue to the extending influence of a bottlehead having an oval cross-section. It will be observed, however, that the extension'of the cone is in a direction cross-wise thereof and not eircumferentially, so that every part of the cone acts with substantially the same degree of resistance as every other part in `causing' the edge-part of the cap flange to interlock with the bottlehead. 'In thisway, irregularities in bottle-heads are eflect'ually laken care of, and the danger 'of'.brea'kage or fracture reduced to the lowest possible minimum. lVhen the' upward 'pressu'reiof the elevating mechanism ceases', the sprin actuated plunger s causes the bottle to low lthe elevating means downwardly, and the cone being internally smooth and without obstruction, the' bottle clears the sealingheapd with perfect freedom.
