head descended upon the neck of the. bottle imposition preparatory to the application of 5'5 pressure to force the capsule into place.

Fig.11 is a horizontal section as on line 1 1 1 1 of Fig. 10. Fig. 12 is an elevation of the inner face of one of the cam-disks whichcause a vertical reciprocationlof the compressionhead. -Fig. 13 is a sectional. view 1n detail through one of the vertical adjusting-screws and its embracing threaded sleeve, throu' h "the operation of which the machine may e adjusted to accommodate bottles-of varying heights.

' Referring to the characters of reference, 1 designates a suitable table supported by the legs 2. Upon'the top of the table and running lon itudinally th'er'eof. is a confining- ;Way 3, .a apted to receive and direct the en less conveyor on which the bottles are presented to and carried from the capsule-applying mechanism of the machine. The endless conveyer comprises a suitable chain 4, (see Fig. 4,) the blocks 5 of which are pivoted at 6 to" the bases 7. Projecting from theupperlfaces of the bases are the ms8, so set as to receive and confine the ottles 9 when .placed therein, said base and; pins forming a bottle-receiving stand. These stands a are placed as closely togetherupon the endless chain as they can be arranged, and upon the bottom thereof. is a rubberlpa d 10, which serves to cushion-the bottle and prevent it The chain 4 passes end of the table 1, one of said wheels being mounted upon a shaft 12,, through themedium of which the chain is.driven.. Mounted upon theshaft of each ofthe sprocket-wheels 11 is a roller 13, which stands upon opposite sides ,of' said wheel and affords .a bearing for the base 7 of the stands oftlle bottles9 as .saidstands are rounding the sprocket-Wheels whenpassing from' the upper to the lower side of the table, and vice versa, thereby preventing the stands from tippingand getting out of position to properly; enter the housing 14,;secured to the under side ofthe table, which embraces and confines said stands while they are being returned to the initial end of-themachine.

Supported above the Itableis a platform 15', carrying the parallel uprights 16, having upon their inner faces the vertical guideways 17, adapted to receive and direct the beveled 1 slides 18, attached to the upper end of the con'ipression-head. The compression-head, as shown in Figs. 3 and 10, is a'hollow cylinder having at its upper edge a threaded flange 20, adapted toscrew into a tapped opening in the lower end of the annular collar 21, to which the lower end of the slides 18 are secured. Within the annular collar 21 is cation between the air-chamber 22 and the air-chamber 25 within said head. The inner wall of the. chamber 25 within the compression-head consists of a diaphragm 26, of rub-' her or other elastic material, forming a socket or chamber 27, separated from the chamber 25 by said diaphragm. The lower end of said diaphragm is secured in the opening of the compression-head by means of a ring 28, having a peripheral channel in which the lower end of the diaphragm 26, which is tubular in shape, is confined by a bindingstrand 29, said ring 28 being confined by a threaded ring 30, which screws against it. The upper end of the elastic diaphragm 26 is secured in the peripheral channel of the ring 38 by means of the binding-strand 39, lying in said channel, the ring 38being confined a threaded disk 40, which screws into the re-. Screwed duced upper end of the head 19. centrally through the collar .21 is a tube 41, whose reduced lower end passes through the disk 40 and ring 38 and extends into the chamber 27. Fitted to reciprocate within said tube is a plunger42, having a rubber buller 43 in its lower end, adapted to bear upon the cork of the bottle. In the plunger 42 is a longitudinal channel 44, into which extends a set-screw 45, which passes through the wall of the tube 41, whereby the plunger is confined inplace within said tube and is permitted a longitudinal reciprocation. Confined between the upper end of the plunger. and the upper end of the tube 41 is a spring 46 of such ;tension as to hold the plunger down against the cork of the bottle, yet per.- mitting the plunger to move upwardly to accommodate a bottle of unusual height. Communicating with the interior of the airchamber- 22 is an air-pipe 47, adapted to be connected by a hose 48 to a source of air or other suitable fluid under pressure.

Lying within the lower opening of the compression-head against the rings 28 and 30 is a bufi' er 31, preferably of rubber, having a lateral flange 32, which lies against the lower end of said head and is confined by the shoulder 33 on the collar 34, which screws onto the lower end of said head, whereby the rubber bufi'er becomes securely retained in place.

, The collar 34 is provided with a lower-cutting the disks 53.

edge 35, which, in conjunction with the compression-head to which it is attached, forms a punch adapted to coact with the die 36, through which the lower end of the head passes in its reciprocatory movement, whereby the tin-foil capsules are blocked out from the sheet 37, which is fed over said die 36 when the head is raised, as shown in Figs. 1 and 9, said die being located in the platform 15 in the path of said reciprocatory head.

The compression-head is caused to reciprocate vertically through the medium of the connecting-rod 49, attached at its lower end to the vertical slides 1-8 and passing through the vertical guide 50, the upper end of said rod having a T-head 51, adapted to engage in the heart-shape cainways 52 in the opposite faces of the o posed disks 53, mounted upon and rotatab e with the main shaft 54, journaled in suitable bearings on the uprights 16' and carrying the belt-pulley 55, through the medium of which it is driven; It willbe observed that a rotation of the shaft 54 will-cause a reciprocation of the rod 49 through the engagement of its T-head inthe camways therein, thereby reciprocating the compression-head. This vertical reciprocation of said head-is necessary to cause it to descend over the neck of the bottle in the operation of applying thecapsules and rise therefrom to permit the capsuled bottle to pass along and a succeeding bottle to take its lace, at the same time severing the capsules rom the strip or blank of the tin-foil and presenting them over the necks of the bottles in succession as said bottles arepresented to said head. To control the passage of air to the chamber 25 in the compression-head, there is employed an ordinary three-way airvalve 56, actuated by'a lever.57, pivoted to the lower end of a vertically-rec1pr0catoryrod 58, whose upper end stands in the ath of the curved lug 59 on the outer face 0 one of As said disks revolveto cause the head to descend upon the neck of a bottle the lug 59 at the proper moment will trip the rod 58 to open the valve and allow a flow of air into the chamber 25. When the In 59 passes from contact with the upper end 0 the rod 58, the coiled compression-spring 60 thereon will return said rod and close the airvalve.

The tin-foil from which the capsules are cut pre aratory to their application to the necks 0 thebottles is provided in the form of a narrow strip or sheet 37, wound upon a .spool 61 and carried between the feed-rollers 62-, the lower one of which turns in a pastebox 62, thence over the die 36, and between the feed-rollers 63. To provide for-i111 arting an intermittent movement to the eedrollers coincident with the upward movement of the. compression-head, there is employed upon the end of shaft 54 a disk 64, having in the side thereof a camway 65, into of the rollers 63.

iparts to the rollers:

struck therefrom upon the next descent of, said punch and carried upon theneck 0f the bottle below. issuch The shapeflof the camway 65 that during the vertical reciprocation of. the compression-head the pin 66 will lie in the concentric portion 81 ofsaid, way and impart no movement through the connected The strip of; tin-foil 37 om which theblanks have been cut is fed by'the rollers 63 into a suitable receptacle part to the endless carrier ,which conveys the bottles into position under the. reciprocatory 'co'mpression headand pro erly-time .the movement ofsaidi parts, "t e shaft 12, which drives the endlesschain or carrier conta1ning the bottle-stands, is turn driven through the medium of the shaft 69, u on the end of which is a beveled wheel 83, w 'c'h meshes with a like wheel 84' on the vertical shaft 85,0n

. a beveled earwheel 86, which meshes with the bevele v ciprocation tles in the sheet and places it over pinion 87on the shaft12.

In the operation of the machine the rota?- tion ofthe shaft 54 will cause-a vertical reof the com ression-head and punch, an intermittent feeding of the sheet of tin foil, and an intermittent movement to the endless carrier, which presents the bot- .path of the reciprocatory head. The bottles are laced in thestands upon the carrier byhan or in any suitable manner and. ;arepresented successivelyin the vertical path of :the reciprocatory head, which upon its descent cuts ablank oftin-foil from the the neck of a bottle, asshown at 88 in Fig. 10, in whichposition the rubber buffer 31 makes an air-ti ht closure upon the neck of the bottle and t e rub-.
