sures of the cap variety, including those termed crown corks, Closures of this type consist of a metallic cap or crown to be locked to the erteriorof the neck of the bottle,V- and of a sealing disk or packing of corlr or the like, whichis united by the aid of a suitable cementing medium with the cap or crown. 'lihere may be either used a fusible cementing medium which is fused when in the cap or crown and `left to cool and set, or the cap or crown is charged with a liquid or viscous cementing material, which is caused to set or to coagulate, as the case may be.

"llhe main objects of the present invention are to provide a simple and' effective ma chine for carrying out a method-or process for the manufacture of closures of the sec ond type, that is to say in which a union hetween the metallic cap and th sealing disk or packing is obtained by the aid of a liquid or viscous cementing medium which `is set or coagulated, for instance, by subjecting the assembled closure to heat.

With these and other objects in View, which will more fully appear as the nature of the invention is better understood, the same consists in the combination, arrangement and construction of parts hereinafter fully described, pointed out in the appended claims and illustrated in the accompanying drawings, it being understood that many changes may be made in the size and proportion of the several parts and details of construction within the scope of the appended claims without departin from the spirit or sacrificing any of the a vantages of the invention.

bored column 22, that is closed at its upper end by a head 23, its lower open end having a flange 2i, the latter resting upon the table,

and being attached thereto in any suitablemanner. Within the column and in the lona gitudinal anis thereof is disposed a shaft 25.. 'lhis shaft is mounted rotatably in the head 23 of said column and in a stepbearing 26, that is formed upon the table 2l. screws 27 and 28, bearing againstthe ends of the shaft, serve to adjust the position of the latter in relation to the table. To the shaft 25 is xedly attached a diskA 29, and to the latter is fastened a transporting wheel 30, that is disposed above the table and is,

preferably, made in the form of a star wheel,

having recessesl, to which the metallic caps of the closures are fed in any suitable manner in their inverted positions. The

hill

Hangs 24. of the column is provided with an annular `groove 2t in its underface in aline ment with the recesses of the star wheel, thereby forming a guide for keeping the caps in position upon the transporting wheel.. 'lihe transporting wheel is intermittently ro tated in the direction of the arrow shown in Fig. 7 of the drawings by the main driving shaft 32 of the machimi.` 'llhis shaft is journaled in bearings 33, which are formed upon the main frame, and carries a loose pulley 3a and a fined pulley 35, the latter being adapted to be geared to any suit-able driving means. 'llo the driving shaft 32 are iooh iut

`keyed two eccentrics 36.with the straps of v which are connected' in the usual manner stance by means of'screws- 39, two blocks 40,

points of the head 38, and have each attachedy which are seated in longitudinal slots 41 in the said column. Each block 40 is made of two sections, denoted by the numerals 42 land 43 (Fig. 9), in engagement with the polnted carried thereby commence their downward stroke, the sleeve 49 and thus the shaft 25 wlll be kept stationary until the anti-frictlon rollers 48 coperate with the screw thread-like portions V67 of the cams. During such time, the sleeve 49 is turned in the directlon of the arrow shown in Fig. 7 of the drawings, a motion in the same direction bemg imparted by the intermediary of the ratchet teethand the pawls to the shaft 25 and thus to the transporting wheel 30.

ends 44 ofadjustingscrews 45, whlch are As the downward stroke of the head 38 is screwed 1nto the head 38 and serve to dlS- `\-continued and the anti-,friction rollers 48 tend the two sections of the blocks, so that they, onA adjusting the screws 45, extend throughout the widths' of the slots. The blocks are disposed on diametrically opposite thereto a cam 46, said cams being located within the column 22 and are adapted to coperate in a manner presently-to be described with lugs 47, upon which are mounted anti-friction'vrollers 48, said lugs beingI carried by a sleeve 49, that is loosely held upon the shaft 25 and provided upon its upper end with a flange 50, on which are formed ratchet teeth 51, that are adapted to coperate with p-awls 52. These pawls are carried by pins 53, which are horizontally disposed in a disk 54, that is fastened by screws 55, or otherwise, to a flange 56, the latter Ybeing ixedly attached to the shaft 25. The pawls are held by springs 57 continuously inv engagement with the Vratchet teeth of the flange 50. A spiral spring 58 1s wound around the sleeve 49,4 its outer end being attached to the column 22 and its inner end -to the sleeve 49 for a purpose hereinafter to be described. With the disk 54 is associated a brake mechanism, comprising, for instance, two brake blocks 59,

lwhich project through apertures 60 in the column vand are provided with brake linings 61,- which contact with the disk 54. The blocks are pivoted at 62 to levers 63, the .late ter being fulcrumed at 64 tothe column. The free ends of the levers 63 are connected by a spring 65, which keeps the brake blocks continuously in engagement with the disk 54. Each of the cams 46 is provided with a straightl upper portion 66, a screw thread-like middle portion 67and a straight lower portion 68. The straight portions of the cams are disposed vertically, as clearly shown in Fig. 12 of the drawings.

The operation of the device so far described is as follows: When the head 38 andthe parts carried thereby are in their upper positions (Fig. 3), the anti-friction rollers 48 upon the lugs 47 vare 1n engagement -with the lower straight sections 68 of the cams," the spring 58 causing the anti friction rollers to abut against the said cams. As now, in the rotation of the main driving shaft 32, the head 38 and the parts friction rollers 48 to follow the cams 46.

The brake mechanism above described serves to prevent the disk 54 from turning too far, that is to say it causes the shaft 25 to stop as soon as the anti-friction rollers engage with the .straight `portions of the cams.

The caps may be passed to the recesses of the transporting wheel either manually or automatically. An automatic device is disclosed in the drawings. This device coacts wlth a charging chute 69, into which the caps are brought in their inverted positions automatically in any suitable manner.

, The chute leads to a channel 69 on the table. On the table is formed a guide. 70 at right angles to the channel 69', and in this guide is held by means of a cover 71 a slide 72. The cover 71 closes also lthe channel 69. The cover is removable, and is held in place by means of a clamp 73, which is pivoted at 74 to the table. Upon disengagn'g the clamp lfrom the cover 71, the latter may be removed from the machine. The slide'72 is actuated by a bellcrank lever 75, which is fulcrumed at 76 to the main frame and engages with the said slide. The other end of the bellcrank lever is connected by a link 77 with the strap of an eccentric 78, the latter being keyed to the main driving shaft 32. The relation between the eccentrics 78 and 36 is such that, when the transporting wheel is at rest, the slide 72 is caused to move toward the same, thus seating a cap in the recess registering with the guide 70. i

The caps received from the chute 69 are transported step by step by the transporting wheel in the direction of the arrow shown in Fig. 7 of the drawings, and are brought, one after the other, into registering position with. the means which introduces'into the same the cementing medium. This means comprises a receptacle 79, communicating through a pipe 80 with a valve casing 81'. The receptacle 79, the pipe 80 inviarml it and the valve casing 81 are attached to the head 38. lllithin the valve casing is disposed a valve 82, which carries at its upper end a disk 83, that is provided with a n plurality of apertures 8d, through which ing against the disk 83, keeps the valve the liquid `cementing medium is adapted to dow toward the valve. A spring 85, bearupon its seat, and projects a pin 89, that is made integral with or attached to the said valve, through the discharge opening 81 in the valve casing. llpon the downward anti-friction rollers 48 coact with the upper straight portion 89 ot the cams, that is to say when the transporting wheel is at rest and a cap is held in registering position, with the cementing medium charging naililahs, the pin 89 iscaused to bear against the inner tace of the cap, whereby the valve `is lifted :trom its seat and the desired troduced into the cap, the latter is trans-` ported to means which spreads the said cementing material over the entire inner face ot the head of the cap. This means comprises inthe case illustrated in the drawings a vertically disposed spindle 87, which is rotatably and reciprocably mounted on the head 38. Suitable means is provided which causes the spindle to reciprocate with the head 38, for instance a nut 88, which meshes I with the upper screw threaded end of the spindle, a ball bearing 89 preventing :triction between the head and the spindle. Upon the spindle is mounted a pulley 99,

' against which bears the lower end of a spring 91, that is coiled around'said spindle, the upper end of said spring bearing against a ball bearing 92, which abuts against the head 38. Rotation is imparted to the spindle by a belt 92', which runs over a pulley 93, that is mounted upon the main drivingshai't4 32, and over the pulley 90, which is, as above described, attached to the spindle 87, suitable idlers 911 guiding the saidl belt. 'lo the lower end of the spindle is attached a block 95, for instance of rubber. rlhe reciprocating head 38 carries with it the spindle 87, which rotates continuously. When the head 38 is near the end ot' its down stroke, the block 95 is brought into contact with the inner tace or the cap. When in such contact, the rotary block spreads the liquid cementing material over the entire inner lace of the head of the cap, which may be held against rotation by any suitable means, (not shown) The head upon its turther downward movement compresses the spring 91'. When the head moves upward, it leaves the block 95 in contact with the bearing 89 and thereby carries the spindle withli't. "llhe purpose ot carrying the spin-` dle slidably upon the head 38 is to permit the said spindle to remain tor some time within the cap so that it is able to perform the .spreading operation properly. lt no sliding motion were permitted between the head and. the spindle, the latter would stay for a moment only inthe cap, inasmuch as the head starts its upward stroke immedil movement of the head 38, and when the\ately atter 1t has finished its downward stroke.. llt is to he observed that the block 95 need not be rotated; it will spread the cementing medium by being pressed against the inner faceot the cap.

Alfter the cementing material has been spreadover the surfaces ot the'- caps, the same are transported, one alter the other, to an assembling plunger 98, Vthat is attached to the head 38. The sealing disks are placed into a vertical tube 97, rwhich is secured to .the table 21 by means or a bracket 97 The sealing disks are :ted by gravity, or otherwise, into a guideway 98 of a plate member 99, which is attached to the dange 2l of the column 22 above the transporting wheel. rlihe plate member is provided with an aperture 199 in alinement with the plunger 99 and in' registering position withan aperture 101 in the Harige-241 of the column 22. 'llhe sealing disks are conveyed in the guideway 98 trom. below the tubular 'member 97 to the apertures 199 and 191 by la reciprocable conveyer 193, which is slidably arranged' inthe guideway 98 and pivoted to a lever 19d, that isv lulcrume'd at 195 to the trame loitr the machine. 'lhelever 1111- is connected by means of a universal joint 19d vith the strap of an eccentric 198, the latter eing keyed to the main driving shaft of the machine. rl`he conveyer 193 engages the sealing disks and transfers the same tothe apertures 199 and 101. Obviously the angular relation between the eccentrics 199 and 39 must be such that, when the head 38 is on its upward stroke, the conveyer 103 will move toward the transporting wheel and thereby transfer a 4sealing disk within the rea-ch of the plunger 99, which, in its downward movement, forces the sealing disk through the apertures 109 and 191 into the metallic cap on top of the Y cementing material therein.

As it happens rsometimes. that one or the .ither of the recesses in the transporting wheel does not contain a metallic cap, it becomes necessary to eject the sealing disk bears a springl 119, that tends to torce the 199 spindle downward toward the transporting wheel. The spindle 107 is disposed upon the -head 38 in such a manner that it is in registering position with a recess in the transporting wheel when the latter is at rest. When, therefore, the head 38 moves downward, the spindle 107 will enter such recess in the star wheel. If an assembled crown cork isseated in this recess, the spring 110 will be compressed by the upward movement of the spindle 107. If, however, a sealing disk only ispseated in the said recess, the spindle 107 will force the same through an opening in the vtable of' the frame so that it will fall into a receptacle below said opening, for the reason that the tension of the spring 110 is greater than the resistance ofered by a sealing disk in'a recess of the transporting wheel. l

The assembled crowns slide down an inclined passage 111 to a heating and uniting head 112. This head comprises an annular member 113, having spider-like arms 114, the latter being made integral with a hub 115. This hub is keyed or otherwise attached to a shaft 116, which is journaled in bearings 117 and 118, the latter being, preferably, made integral with the main frame of the machine. This shaft is continuously driven from the main driving shaft, and for this purpose the latter is provided, for instance, with a worm 113, meshing with a worm gear 120, that is ixedly attached to the shaft 116. Upon the annular member 113 are formed a suitable number of radially extending and outwardly projecting ribs 121, which are covered by an annular curved flange 122, whereby a plurality of curved passages 123 are formed in the uniting head, said passages registering, as the said head is being rotated, with the inclined passage 111, and receiving thus, me after the other, assembled crowns from the said passage 111. The flange 122 is formed upon a cylinder 122', that is attached by screws or otherwise .to the ribs 121. The crowns are arrested in their downward motion in the passages 123 by a stationary arch-shaped platform 124, which projects between the annular member 113 .and the ange 122, and is attached to the arm 125 of a ring 126, which is drawn over the hub 115. The ring 126 is kept stationary by arms 127, whichv engage with downwardly projecting lugs 128 of a' bridge 129, that is fastened to the table 21. Plnngers 130 are slidably arranged in the cylinder 122 in alinement with the passages 123, said plungers being located parallel to the longitudinal axis of the head and carrying lugs 131, which are adapted to coact with a cam 132, that is attached to the bridge 129. Upon each plunger is coiled a spring 133. These .'springs'tend to force the plungers into the passages 123. The cam 132 is disposed in the path of the lugs 131 upon the plungers, whereby, as the head 112 rotates, the plungers are forced against the action of their springs 133 out of the passages 123 before they arrive opposite the passa e 111. When a passage 123 arrives at this point, an assembled crown cork will slide into the same and rest upon the platform 124. When then the corresponding lug 131 is disengaged from the cam, the corresponding spring 133 forces the plunger against the assembled crown cork, thereby placing the parts under compression and holding them in this condition until the closure makes very nearly a revolution around the shaft 116, when the lug 131 of the plunger again arrives at the cam 132, whereby the plunger 130 is disengaged from the closure, allowing the same to fall, as soon as it drops off the platform 124, into a chute 134, the latter being attached to the arm 125.

While the closures are being carried by the head 112 and held under pressure, their cementing medium is coagulated or set by suitable means. For this purpose a suitable fluid, for instance steam, is admitted into an annular channel 135, that is formed in the annular member 113 in rear of the passages 123. In the channel 135 is provided a radially extending partition 136, the heating Huid being admitted into thel channel on one side of said partition, travels around said channel and leaving the same `on the other side of the partition. The fluid `flows to the channel 135 through a pipe 137, that communicates with a bore 138 in the hub 115, said bore being connected by a pipe 139 with the channel135 on one side of the partition 136. The other side of the artition is connected by a pipe 140 with a ore'141 in the hub 115, said bore communicating with a chamber 142, to which is connected a pipe 143. Stuliing boxes or other suitable means may be provided to prevent a leakage of the Huid in the direction of the longitudinal axis of theshaft 116. The Huid, admitted through the pipe 137 and the passages communicating therewith into the channel 135, ows through the latter and leaves through the pipe 143. The temperature of the fluid is maintained at a point sufficient to coagulate or set the cementing medium within the assembled closures. The coagulation results in a firm union between the parts of the closure.

It is to be observed that upon the machine herein described cementing media can be used which are fed to the caps in their hot state. To the uniting head 112 is led in such cases a cooling fluid.
