for the manufacture of bottle closures of theji class known as crown cork scaling capsor .r

closures. Closures of this type comprise usually three parts, that is a metallic cap or crown having a corrugated flange to be locked to the exterior ot the bottle neck, a sealing disk or packing of cork or the like, and a disk ci' impervious material interposed between the metallic cap and the packing' disk.v ihe purpose of this interposed impervious disk is to provide n hermetic .seal and to prevent bottled liquids troni taint by contact with the metal of the cap and the incident `corrosion ci" the nietal.

'Heretotoie as far as known, the interposed dish of impervious inaterial was always tuv sible, serving at the saine time to unite the sealing disk of cork or other material with l in manufacturing the l the metallic cap.

closures, the. interposed impervious disk, therefore, had to be subjected to heuting action to properly fuse the saine, and the assembled closures had to be subjected to pressure while the binding' material was hardening in order to unite the packing disk a I i e,

withthe metallic cap. Most ot the inachines heretofore in use applied cooling deof the closure are in no way subjected to heating action, which action obviouslvaitfectsn greet deal the cork oi picking` disk in that it iinpaiis the sealing properties oll the saine.

In the cylinder is larranged a feeding drum 33, said drum being keyed to a shaft 34, which is rotatably supported in bearings 35, 35, said vbearings being carried by the frame memsponds substantially to the height of said head portion. The iange portion of the cap projects beyond the periphery of the drum and is arranged in the groove 24, as clearly shown in Fig. 12 of the drawings. li a. metallic cap is placed through the slot 24 into the groove of the cylinder and a groove of the feeding drum,'it will he observed that, by rotating vthe feeding drum,

- the said cap will be moved alon'g the groove 24 in said cylinder. In moving along this groove, it will slide along the said groove in the feeding drum and be disengaged from themecbanism as soon as the said groove in the drum registers .with the outlet 32 of the groove'24. This outlet may be somewhat enlarged to permit of an easy disengagement,

of the cap from the mechanism.

The driving shaft 38 of the apparatus is 'journaled in bearings 39, 39, which are mounted upon the base plate 20. A driving pulley 40 is keyed or otherwiseA attached to the shaft 38, andl rotated by the intermediary of a suitable belt from a countershaft or a motor shaft. To one of the bearings 3S is attached a bracket 41, supporting a receptacle 42, to which leads a chute 43 from the outlet ofthe groove in the cylinder.

Rotary motion is imparted to the feeding drum 33 from the shaft 33 by an eccentric 441i, the rod 45 of which is pivoted at46 to a plate member 7, which is slidably arranged in guides 48, 48, whiclillatter form part of one of the bearings 35. This plate member is provided in its inner surface with. a semicircular groove 4,-, adapted to be engaged in. a i hat .matter to be described by pins e, f deh are mounted upon the E outer: tace of a disk 5l, the latter being iixedly attached to the shaft 34 of the feeding drum 'In one of the sides of the plate member 47 is formed a recess 52, in which is slidably arranged a'lateh 53, held by means of a spring 54 in its normal outer position, shown in full lines in Fig. 10 of the drawings. There are four pins -upon the disk 5l arranged 90' apart at a distance which corresponds to the width of the plate member 47. In the position shown in full. lines in Fig. l0 of the drawings the reciprocable plate member is in its uppermost position, in whichr case there are two pins upon eacli'side of said plate member. The disk 51 and thus the feeding drum will be thereby held firmly in position until the eccentric in its further rotation starts the downward movement of the plate member. During the downward movement of said plate member, the pin which is denoted by the numeral I is moved in the direct-ion of the arrow shown in Fig. l0 in an arc-shaped path downward until itrcaches the position II, causing thereby one-quarter of a revolution ofthe feeding drum 33. That pin which has been, before the movement started, in the position II moves in an arc-shaped path along the groove 49 until`it reaches the position III; the pin which has been in position III moves into position IV outside of the plate member 47, and that pin which has been in position IV moves in an arc-shaped path along the groove 49 until it reaches the position I. During the upward movement of the plate member 47, the pins are not acted upon by the said plate member, whereby the drum will be kept stationary. It is obvious that when, in the upward movement of the plate member, the inclined surface 55 of the latch 53 comes into contact with the pin I, it will be forced into the recess 52 against the action of the spring 54, which will, as soon as the point of said latch is disengaged from the said pin, cause the said latch to assume its position shown in Fig. 10 of the drawings, whereby the plate member is again ready for action. It will be noted that, since the four pins abut against the sides of the member 47 during the upward movement, the drum 33 will be kept fixed during the upward movement of said plate member. While the drum is kept stationary, two of its grooves register with the apertures in the cylinder.

The metallic caps are fed to the cylinder y 23 iny their inverted positions, preferably automatically, though a chute 56, whichdelivers them to a platform 57 in a direction substantially at right angles to the longitudinal axis of the cylinder, and more particularly opposite to the slot 24 in the said cylinder. In alinement with said slot is slidably mounted a feeding linger 58,l normally kept by means of springs 59, which bear against the cylinder 23 and against lugs 60, against an inclined surface 6l upon the upper end of the reciprocable plate member 47. When this plate member moves downward, the said springs will force the ieeding finger S outward am ermit thereby the feeding of cap onto the platform 5i' in alineinent with the slot 2e and a g1 oove 3G in the druin. As the plate nie-nn ber i? moves upward, the said cap Will be fel through t ie slot 24 into engagement with the groove 25rin the cylinder and the gi oove 36 in the drinn, the inclined suriace 6l aetingiagainst the "feeding linger and crcing the same toward the cylinder and the drum. When the cap is eng "vl by the cylinder and the drum, and the r in is rctated in the manner above described, it ivll be fed along' the groiive 24e a distance corresponding to an angular travel oli 900 of the drum, stop at such point until au- -otier -cap is fed into the groove, and be thon moved along a distance corresponding .in the trough and is attached to the angular `travel of 9G@ of the drum, Wl. ereb'y it will come into registering position with the aperture Q7 in the bottom ol? the drum andstop there in i.ipriglit posi-- tici, or in other words positioned with its open end downward` during .the up y'1rd movement of the plate member e?. filhile the said plate member is moving upward anc the drum is kept stationary. an adhesive substance is applied to the .in

The plunger 63 is shown infde'tail in Figs. le and l5, and comprises a ioliow member, having a plurality or" per c'ations 5ft in its Wall and provided with a head which is screwed or otherwise attached to the body thereof. ln said cap are provided a large number of per'lorations iithrough which project pins 6?', which srevslidably arranged in the plunger, their loiyer ends being seated in recesses 68" in the bottom portion of the plunger, To limit the outward. movement of the pins 62", the

By applying the adhesive material totlie caps positioned with their ropen ends downward, all of the seme will receive the same quantity of adhesive material.. The cap is then transported step by step until it registers in an inverted position with the aperture 28 in the top of the cylinder lWhen inthis position, a disk oi' paper or any suitable material placed into said cap.

ri`he disk TQ, shown in Fig. 7 of the draw inns, is out from strip 72, 1wound upon a 'reel 79% Whiclris suitably `journaled in the iframe of the machine and from which the strip is conducted into .a guide Tl,` to pass between the eedingrollers 75 and 76. These feeding rollers are suitably ournaled in bearings on the lower one7 that'is the feeding roller 7G, proiectingf through a slot Z7 in the `guide 74C above the lower planeA of the latter, its shaft Yf being; provided with a ratchet Wheel 78, the teeth of which mesh with a paw] T9, which is pivoted SO to a rod 81. Villien this rod moves upward7 it will rotate'the shaft 76 and advance thereby the strip 72 in the direct-ion of the arrov.Y shown in Fig. 11 toward the cutting1 means 82. rThe feeding rollers are rotated intermittently, that is to say they will rotate While the rod 81 is moving upward and kept stationary while the latter is going downward. Tv cutting` means :comprises a tubular cutter 82, which is secured in any suitable manner to an arm ,83? the latter being slidab'ly 'arranged in ver tical guideways 84e of brackets 85, which. ar'e attached to the top et the cylinder 23, T he arm 83 is carried bythe rod 81 above mentioned. rThis rod is pivotally connected with a 1'0d86 of an eccentric 87, which vlatter is keyed to the driving shaft The e'ccent'rics S7 and 4Miare keyed at an angle oi' about 1800 relative to each other to the driving` shaft 38.

rramc of the machine, the3 ward, the weight 89 will force the stem downward and thereby the paper disk into the cap. After this, upon the further up ward movement of the ,arm 83, the latter will engage the Weight 89 *and lift thus the stem 88. From the foregoing it will be observed that during the downward movement of the eccentric rod S6, or in other words while the metallic cap is being transported into regis tering position with the opening 28 in the cylinder 23, the strip 72 is fed into the proper position, and during the downward movement of the eccentric rod 86, the disk is cutand deposited into the cap, or in other words the cutting operation 'takes place while the cap is held stationary. The disk having been deposited into the metal cap, the latter is conveyed step by step into registering position with the opening 29 in the bottom of the cylinder to be held there positioned with its open end downward in order to receive upon the exposed surface of the disk adhesive material. The adhesive material is applied to the -disk by a plunger mechanism 90, which is arranged within the tank 62, and is in all respects identical with the plunger mechanism 63 above described The plunger 90 is attached to the yoke 65. After this operation the metallic cap with the paper disk is transported step by step to the opening 39 in the top ofthe cylinder 23 to receive in its inverted position a scaling disk.

Above the opening 30 arranged an assembling plunger 91, which is slidably mounted in vertical guides 92, and is eonnected by means of an arm 93 with the arm 83 of the cutter 82'. The sealing disks 9e are placed in a vertical tube 94E, which is attached to the guide 92 by means of a bracket 95, and is provided ywith a longitudinal-slot 9G, through which a finger piece 97 of a weight 98 protrudes, said weight being placed on top of the sealing disks and serves tol feed the said disks .into a guideway 99 of a reciprocable conveyer 100. The guideway 99 is provided in its bottom with an opening 101, which registers with the apertureBO in the top of the cylinder 23. The jouter end of the reciprocable con'yeyer 100 contacts with an inclined surface 102 ofv a'block 103, which is carried by the rod l81. A spring 10e serves to force the said conveyer continuously into contact with vthe inclined surface 102 of said block. The con- A veyer 100 engages the lowermost pf the sealvso ing disks 94 in the tube 9e, and transfers the samento the'opening 101 during the upward movement 'of 'the rod 81, or in otherv words while the assembling plunger 91`is being lifted. The latter will in its' dowirA ward movement force the sealing disk through'the opening 101 and aperture 3()4 into the metal cap. The opening 101 in the bottom ofthe guideway 99 'tapers toward the notarse M cylinder`23, its upper end being larger'than the diameter of a sealing disk 94', and the diameter at its lower end bein somewhat smaller than that of a sealing dis For this reason the sealing disk will be compressed to some extent when it passes through the opening 101 and will, when forced into the cap, expand to be held thus firmly in the cap. The assembling plunger, besides that 1t forces the sealing disk on top of the disk 72, exerts at the same time pressure upon the component parts of the closure and'iirmly unites thereby the said parts, for the reason that adhesive material is still in its semisoiid condition when the parts of the closure arrive at the aperture 30. During the next quarter of a revolution of the drum 33 the assembled closure is transported to the outlet. and discharged there into the chute 13, in which it slides into the receptacle 42.

ltecapitulating now the operation of the machine, we find that the feeding drum 33 moves intermittently making at each movement a quarter of a revolution and stopping then while the plate member 47 moves upward. During the movement of the feeding drum, a disk 72 is cut and a sealing disk or lcork disk is fed in proper relation to the aperture 30 in the top of the cylinder 23. During the rest of the feeding drum, the eccentric rods 67 and 86 move in opposite directions and actuate thereby the plungers 63 and 90, the cutter 82 and the assembling plunger 91, the plunger 63 serving to apply adhesive material to the inner face of the head of the metal cap, the cutter 82 to cut the disk from the strip 72 and deposit the same into the cap, the plunger 90 serving to apply adhesive material to the exposed surface of the disk, and the assembling plunger 91 serving to force the sealing disk into the cap and to unite the parts of the closure.
