To all whom it may concern:

Be it.- known that I, BURTIS L. BUCHANAN, a citizen of the .United States, residing at Charlotte, in the county of Mecklenburg and State of North Carolina, have invented a new and useful Machine for Manufacturing Bottle Crowns or Caps, of which the following is a specification.

This invention has reference to improvements in machines for manufacturing bottle crowns or caps and its object is to produce a machine which will finish the crowns or caps ready to be applied to bottles with great rapidity.

In accordance with the present invention there is provided a rotatable member in the form of a carrier having receptacles adapted to receive bottle caps in blank, that is without the usual cork filling, and in conjunction with this rotatable carrier with its circular series of receptacles there is provided a suitable number of plungers, the first of which in order is designed tocut from aweb of suitable fabric such for instance as a paper strip having cementing material on each surface, disks of such size as to fit snugly within the caps. At a. subsequent point in the cycle of operations the cap with the paper disk therein is brought under another plunger by means of which a cork disk coming from a suitable reservoir through. the intermediary of appropriate mechanism, is deposited, and finally the caps are brought to another plunger which forces the cork --disk already deposited therein firmly into the cap, after which the caps are automatically removed from the machine and are then subjected to suitable sterilization. The invention however will be best understood from a consideration of the fol lowing detail description taken in connection with the accompanying drawings with the understanding that the invention is not confined to the exact embodiment thereof illustrated in said drawings, but the structure may be variously modified in the form and location of parts and in other respects so long as the salientfeatures'of the invention are retained.

In the drawings, Figure 1 is a plan view of the machine with some of the remoter parts not visible in the view, shown in dopted *ig. 2 is a side elevation of the structure of Fig.

Fig. t is an elevation of a portion of the machine, showing the paper feeding mechanism. Fig. 5 is a detail section through the rotatable carrier with parts in section, showing the ejector mechanism for the finished crown. Fig. 6 is a perspective view of a perforated plate used in connection with the paper cutting mechanism. Fig. 7 is a detail view of the paper winding drum showing a means for compensating for the increasing diameter of the paper wound thereon. Fig. 8 is a detail section of a punch used in the ma- 'chine. Fig. 9 is a view of a portion of the actuating structure for feeding the cork disks.

The machine of the present invention is not designed to shape the metal parts of the bottle crown or caps but these metal parts are to be shaped in another machine suited for the purpose but which machine in itself forms no part of the present invention and is not shown in the drawings. The shaping machine and the machine constituting the subject matter of the present invention are designed however to work in synchronism fora purpose which will presently ap- In the drawings there is shown a frame 1 which however is but a portion of the main frame of the machine, which main frame will be of such size and structure as to adapt it to the purposes of the present invention.

Above the'frame 1 is a rotatable carrier 2 in the form of a disk and this disk may for structural purposes be made of two pieces of thesame size as indicated in the drawings or may be made entirely of one piece as found desirable. In the following description this disk-like carrier will be considered as made of one piece. About the carrier near the periphery thereof is formed a circular series of recesses 3 of such size and shape as to readily receive and hold a shaped bottle cap or crown coming from the shaping machine, with the upper edge of the cap, which cap is deposited; in the receptacle in an inverted position, either flush with or slightly below the surface of the said disk or carrier 2. In the bottom of each receptacle 3 is a small disk or plate 4 having a central stem 5 extending through a perforation in the bottom of the disk 2 and said stem extends below the lower surface of the disk 2 so as to be in the path of a cam block 6 on the frame 1 or other fixed portion of the structure. The urpose of this cam block is to engage the pins 5 of the disks 4 and elevate the said disks 1 to a suflicient extent to lift the crowns or caps so that their lower surfaces as located in the disk 2 are flush with or above the uppersurface of said disk. This is for the purpose ofafacilitatingthe removal of the caps from their seats in the disk 2 after they havd-been finished by their treatment in the machine forming the subject matter of the present invention and the cam block 6 is appropriately located for this purpose. In order to cause the caps to'lea ve the receptacles 3 after being elevated by the disks 4 there is provided a finger 8 in the path of the receptacles or seats '3. This finger 8 is suitably inclined to direct the elevated caps toward the er iphery of the disk 2 and they ultimately all therefrom into a suitable receptacle which latter however is not shown in the drawings.

Adjacent to the point where the finished caps or crowns are removed from the disk 2 provision is made for the placing of shaped but otherwise unfinished crbwns into the seats in the disks2. For this purpose immediately adjacent to the finger 8 there is located a funnel or conduit 9 in close relation to the bottom or discharge end of which the pockets or receptacles 3 travel as the disk 2 is rotated step by step in a manner to be hereinafter described. This funnel receives the caps or crowns one at a time from the shaping machine and the shaped crowns fall with the skirt upward into the receptacles 3.

The operations of the shaping machine and of the machine forming the subject matter of the present invention are so timed one relative to the other that a crown is shaped by the shaping machine and then falls into.

the funnel 9 and is directed to a pocket 3 and becomes seated therein, then the disk 2 is turned a step to carry the seated crown toward the portions of the machinti}, for treating it while the next pocket inorderis carried under the funnel 9 and then receives the next shaped crown which becomes seated in the corresponding pocket, and then the disk 2 is turned another step, and so the operation proceeds in this manner so long as the machines are running.

The first operation to which the shapedcrown is subjected after being seated in a pocket 3 is to have a disk of paper inserted therein. For this purpose there is provided a paper feed mechanism for a stri of paper of appropriate width and means or cutting a disk from said paper strip and forcing iin the cap are provided. For this purpose there is connected on the frame 1 a post or standard 10 on which'there is secured or formed a bracket 11 carrying a reel 12 designed to receive'and hold a roll of paper 13 in the form of, a narrow strip' having cementing material on both sides for a purpose in Fig. (3 and this plate has a perforation 17 under which the pockets 3 are brought suc- (:eSSiWly.

The post 10 carries one end of an' arm'18 pivotally connected thereto and this arm carries a plunger rod 19 passing through brackets 20 projecting from the post 10. The

u pperend of the plunger rod 19 is formed with a bifurcated or forked head 21 straddling the arm 18 and connected thereto by a pivot pin 22'passing through a slot 23 in said arm. The connection between the arm 18 and the post 10 is by means of a pivot pin 24 passing through a slot 25 in the corresponding end of said arm.

The lower end of the plunger'rod 19- carries a head 26 having an annular cutting edge 27 adapted to extend through the perforation 17 in the plate 16 in shearin relation thereto. The len th of travel 0 the plunger head 26 is su cient to carr the cutting portion thereof into close re ation to the bottom of a receptacle or pocket 3 so as to force a paper disk cut by the action of the cutting edge 27 in slot17 into the cap to tie en thereof.

After leaving the cutting head the paper band or ribbon is directed away from the disk 2 over a roller 28 mounted upon ;a bracket 29 risin from the frame 1 or other fixed portion ot the structure in close relation to the edge of the disk 2, and from this roller 28 the paper passes to a winding drum .0!" reel 30 mounted on a shaft 31, the shaft however being in frictional engagement. with the reel or drum by a driving sprin 32. This is to permit a certain amount of slip between the shaft 31 and reel or drum 30 to allow for the increasing thickness of the roll of paper winding upon the reel 30. The periphery of the drum or reel 30 may be in driving engagement with the roller 28 so that the latter will aid in keeping the paper in a taut condition under the punch, es cially if the reel 12 works somewhatsti y The means for driving the shaft 31 will be described hereinafter, in connection with other structures.

Depending. from the frame. 1 or suitably mounted on other fixed portions of the structure--are journal bearings 33 for a main or drive shaft 34 carrying at one end a pulle 35 by meansof which power-may be applie replaced by an electric motor or other, form,

of drive as is customary under modern practice.

Upon the'drive shaft there is mounted a bevel gear 36 provided'with a hub 37 to which is secured one member 38 of a friction clutch. The other member 39 of this clutch is made fast on the shaft 34: and carries a friction plate l0 which together with the member 39 houses the friction member 38. The plate 40 is held to the friction member 39 by pins all surrounded by springs 42 tending at all times to move the plate toward the said friction member 39. The friction member is constrained to be at all times active so that the gear wheel 36 will be driven except when the resistance to its motion exceeds a predetermined limit. The gear wheel 86 is in mesh with another gear wheel 13 fast on the under side of the disk 2 which latter is also provided with a circular series of ratchet teeth 44 concentric with and exterior to the gear wheel 43. The disk 2 as well as the parts carried thereby are centered for rotation on the frame 1 by a rod 45 capable of longitudinal movement through the disk and frame and formed at its lower end below the main frame 1. with. a cam frame 46 capable of moving with the rod 45 in the direction of the length of the latter between guide members l7 carried by the main frame 1 or other fixed portion of the machine- The upper member of the frame i6 is semi-circular in shape as indicated at 418, while the lower member 49 is straight and substantially parallel with the table or disk 2. The shaft 34 extends through this frame 46 and within the frame the shaft carries-a cam 50 terminating at its active end in an anti-friction roller 51. The action'of the cam 50, onengaging the'member 49 of the frame 46, is to force said frame in a downward direction and on engaging the curved member 48 to elevate said frame. ,In order to center and steady the disk or table 2 the latter is provided with an elongated hub on its upper face through which hub the rod 45 extends.

.The upper end of the rod 45in the par ticular structure shown'in the drawings carries athree way head 53, two of themembers of the said head being diametrically o posite and the third disposed at an angle of 90 to the other two. One of the members of the head 53 has pivoted thereto the corresponding end of the arm 18 and the diametrically opposite portion of the head 53 has pivoted thereto -in like manner another arm l the remoter end of which latter is pivot-ally connected to the upper end of a post diametrically opposite the postv 10 before referred to and the connection between the arm 54: and the post 55 is by way of a pivot pin 56 passing through a slot 57 in said arm 54 similar to the con nection of the arm 18 to the post 10. p

The post 55 is provided with guide members 58 projecting laterally therefrom and through these guide members there extends the stem 59 of a suitable plunger 60 fast on the lower end of said stem 59. The upper end of the stem 59 is formed witha head 61 shaped to straddle the arm 54; and is secured thereto by a pivot pin 62 passing through a slot 63 in said arm.

The third member of the head 53 carries an arm 64 similar to the arms 18 and 5a and this arm carries a plunger 65 similar to the plunger 60 before described. The outer end. of the arm 64 is secured to a post 66 like the posts 10 and 55 before referred to and rising from the frame 1.

Erected over the table or disk 2 is an upright tubular member 67 constituting the magazine for the cork disks which are designed to be inserted in the caps or crowns for the bottles. The bottom of this reservoir 67 is in close relation to but elevated a short distance above the upper surface of the table 2 and in operative relation tothe lower or discharge end of the reservoir is a device for carrying the cork disks one at a time into proper relation to the crowns or caps which have been deposited in the receptacles 3 and which have already received the paper disks.

The device for transferring the cork disks from the reservoir into operative relation to the receptacles 3 comprises a pair of aws 68 and 69 of a thickness corresponding to that of the cork disks and having the active po'rtions curved to grasp a cork disk. Each jaw is provided with an arm 70pivotally supported upon a pin 71 journaled in brack ets 72: mounted on an appropriate fixed pets The arm I 70 of the jaw 68 is fasten the pin 71 While tion of the frame of the machine.

the arm 70 of the jaw (39 is loose, thereon but. the two jaws are held together by means of a spring 73 so that under appropriate conditions'these jaws may separate a limited distance. The lower. end of the pin 71 has fast thereto an arm 74 under the control of a spring 75 so that the two jaws have al ways a normal tendency to return to a po: sition coincident with the bottom of the res-' ervoir 67. The pin 71 alsocarries a side extension 7 6 in the nature of a crank arm in the path of a cam 77 upon a cam drum 78 mounted on the shaft 34. The jaw 68 has a side extension 79 designed to close the lower end of the reservoir G'Yagainstthe escape of the cork disks when the jaws have been-.inoved away from the said reservoir toward one of the receptacles 3 in the disk 2.

"the, jaw 68 and its extension 79 are of such thickness as to readily pass beneath the I at Mitt

. greater" extent.

lower-end'of the reservoir 67 and the upper surface of the disk 2 while the jaw- 69 has a portion somewhat thicker so as to engage the side of the reservoir 67 jaw from moving toward the reservoir to a This is for the urpose of slightlyseparating the jaws to talie in disks of the greatest diameter, since the disks may vary sllghtly in diameter and when the jaws are moved toward the receptacles 3 then the spring 73 which'was slightly extended when the jaw 69 engaged the reservoir 67 will brin' these jaws again into close relation there y' firm y clamping the disk between -t em.

The operation of the parts described is- As soon as the plunger 60 has been retracted then the arm 76 has escaped from the action of the cam 77 and the spring 75 returns the parts'to their normal position with the jaws beneath the bottom of the reservoir and an- .other cork disk is dropped thereinbetween.

- After the cork disk has been-deposited in the crown or cap the latter is carried forward until ultimately it comes under the plunger 65 and the action of this plunger is to force the cap firmly into place. Since the last named plunger does not have to coact with the cork holding jaws it may be made to fit quiteclosely into the crown and inequalitiesof the fit of the cork may thereby be remedied. v In the operation of the machine it is necessary that the disk 2 be fed step by step in proper sequence'with the other operations. For this purpose there is provided a pawl or dog 79 suitably pivoted upon the frame 1 or other fixed portion of the machine and this dog has an extension 80 on one side of its pivot point in the path ofa tooth or cam projection 81 on the shaft 34. A spring 82 acts on the dog 79 in opposition to the tooth or cam 81. The end of the dog 79' remote fromthat acted on by the cam 81 is in normal engagement with'one of the teeth 44 on the under side of the disk 2. Suppose now that the shaft 34 is in constant rotation the disk 2 will participate in such rohtation until a tooth 44 comes in engagement with the dog 79 and then further rotation is-arrested and the clutch member between the shaft 34 and the gear wheel 36" will slip. member or tooth 81 will be brought into engagement with the dog 79 and the latter will be moved awav from the tooth 44 with and prevent the disks p r which it was in engagement and then the clutch will become active and the disk 2 will participate in the movement of the shaft 34. The cam or tooth 81 however is made so short that before another tooth 44 can pass the dog 79 the latter has been returned into the ath of the next tooth by the spring 82 and consequently the rotation of the disk 2 is again arrested. The proportions of these parts are such that the disk 2 will be rotated a distance equal to the. distance between the centers of two adjacent rece tacles 3. Thus at every rotation of the shaft 34 the disk 2 is advanced one step;

The shaft 31 carries atthe end remote from p the drum 30, a bevel gear 83 in mesh with a bevel gear 84 on a stub shaft carrying a star wheel 85 in the path of the teeth 44. When the disk 2 is moved a step then the star wheel is moved-a tooth and the paper 13 is fed accordingly. With a machine such as described the sequence of operation is as follows: The shaped caps or crowns come one by one from the shaping machine and are deposited in the poc ets or receptacles 3 between each step y step movement of rotation of the disk 2. Then each crown is brought in succession under the paper punch which inserts into said crown a disk of paper carrying cement on each side thereof. The crowns with the paper disks therein are then brought one after the other into operative relation to the punch'which causes the deposition of a cork disk from the cork carryui jaws coming from the magazine. Then t e cork disk is forced firmly into the cap or crown by the third member which is the plunger 65. Finall the caps with the corks firmly embedde therein are brought to the point where the cam block 6 becomes active and the caps are elevated so that.their under surfaces are flush with or above the to surface of the disk 2. Now these-lifte caps or crowns are swept off of the disk 2 by the action of the finger 8 and ultimately drop into a suitable receptacle. Finally the finished caps or crowns are subjected to a sterilizing process which will cause a sulficient softening of the cement on the paper on both sides of the latter'to cause adherence of the paper to'the metal of the crown or cap and the adherence of the cork to the paper, thus thoroughly cementing the cork disk in the crown. The finished crowns are now ready to be applied to bottles in the usual manner.
