Patented Dec. 29, 1908.

Application led May 31, 1907. Serial No. 376,620.

To all whom it may concern:

Be it known that I, HERMAN OsswALD, a citizen 'of the United States, residing at Brooklyn, county of Kings, State of New York, having invented certain new and useful Improvements in Bottle Cap -Making Machines, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to a machine for making bottle caps.

It has for its princi al object to make cornplete, ready for application to the mouth of a bottle, a sheet metal capor closure with suitable cushioning and packing materials therein.

'In the. drawings, 1 indicates asian entirety the main frame' of the machine; This may be of any suitable construction. For illus- Fig. 14v

tration, I have shown it, of the nature of a press frame, comprising two side standards or supports 2, 2, suitably joined near their lower ends by cross and positioning bars 3, 3.

4 is a bed supported by the said standards and having extending upwardly from either side of the rear thereof the uprights 5, 5.

6 is a vertically reciprocatable slide mounted to move u and down in suitable guides 7, 7', carried y the uprights 5, 5, respectively. The mounting and operation of t is slide may be of any suitable and Well known nature. For Aexam le, I have shown a main drive shaft 8, horizontally disposed and mounted transversely at the upper end of the main frame in bearings 9, 9', carried by the uprights 5, 5', respectively. Between these earings, the said shaft 2 has secured to or formed integrally with it an eccentric 10, which is connected by suitable eccentric straps 11 and pitman 12 to the.'upper end of the slide 6.

13 is a power transmitting wheel, preferably a belt wheel, loosely mounted on one end of the said main shaft 8. This belt wheel is locked to and .released from the said. shaft by means of a dog 15 fitted to slide longitudinally of the shaft in a groove 8 in an enlargementf 8a on the shaft, the outer end of the said dog being adapted to be projected into andl withdrawn from the path of travel of suitable lugs or projections on the inner face of the hub of' the said wheel. Since the mechanism' for connecting the said power transmitting wheel 13 to anddisconnccting it fromthe drive shaft 8 forms no part of this invention, it is not deemed necessary te fiescribe it in detail, as any suitable clutch mechanism may be employed for the purpose. The specific one shown in the drawings is fully described and claimed in my Letters Patent of the United States, No. 7 72,1 13 dated October 11th, 1904-. It is sufficient for the purposes of this application to know that the dog 15 is normally pressed outgages the lug 16 on the ring 16, and prevents the further rotationof the ring 16 and the permits the outward movement of the dog 15- and its engagement with the power wheel 13. The movement of the switch plate 17 may be controlled by a foot treadle 17 having suitable connection, not shown, with the. said switch plate.

20 is a disk diametrically grooved and secured to or formedintegrally with the shaft 8 at its opposite end to the one carrying the belt wheel 13, and preferably outside of the upright 5. -The groove in the disk 20 is preferably T-shaped in cross section to receive the head and shank of a crank pin or arm 21, which is adjustable along said groove relatively to the axis of the shaft 8.

22 is a horizontally disposed plate, secured in any suitable manner to the upper surface of the bed 4 and carrying a pivot or center plate 23, which may. be formed integrally with it, or secured to it in any suitable manner.

24 is a rotatable annular dial having an annular series of cap-receiving apertures 25 through it, each one of which apertures is lshaped preferably to the form of the metal blank from which each metallic cap is made. 26 are grooves, three in number', extending in the said dial plate 23 radially from the center of each cap aperture or blank receiver 25 therein.

27 are reciprocatable cap or blank-engagin grippers or jaws, each having a horizonta ly disposed arm 27 mounted in one of said grooves 26, and a downwardly extending ver- 'tically'disposed arm 27a, which preferably rests at its lower end upon the upper surface of the plate 22. Each of these grippers has its upper inner corner beveled, asindicated at 27h, to permit the easy introduction of a cap blank into the holder, and the inner vertical face of each gripper is grooved, as indicated at 27C, to conform to the curvilinear surface of the cap or cap blank. The upper surface of each gripper is transversely grooved, as indicated at 27d, to receive .a transversely arranged retaining strip or plate 28, which at either end is secured to the dial plate 24 and is adapted to hold the gripper in its groove or recess 26.

29 is a spring bearing at its. outer end against the vertical wall of the grooveor recess 26 and at its inner end against the vertical leg 27a of the sliding gripper or jaw mounted in the groove, and is adapted to normally press the gripper toward the center of the cap-receiving aperture 25.

4adjustable connectin rod 38.

30 are notches equally spaced apart about the periphery of the dial plate 24 and adapted to receive the toothed or pointed end 31 of a awl 31, which latter is pivoted at 32 to a sli e 33 mounted in a guide 34 carried by the main frame.

35 is a spring wound about a stud 36 carried by the slide 33. The front end 35 of the said spring presses against the front free end of the pawl 31 and tends normally to force the tooth 31 on the pawl toward the dial plate 24. The front face 31 a of the said pawl tooth is straight and adapted to engage and press against the front wall of the recess 3() in the dial plate which it enters. From this straight front face 31a, on its dial side, the tooth is curved away from the dial, as indicated at 31h, so that the pawl will readily disengage itself from the dial plate as it moves rearwardly with the slide 33.

. Near its rear end the slide 33 carries two upwardly projecting ears or lugs 36 between which, by means o a'pin 37, is pivoted an 'Ihe rear end of this connecting ro is pivotally connected at 38 to one arm 39 of a bell crank lever 39, which is secured to a rock shaft 4() extending through and suitably mounted in the upright 5 of the main frame.

41 is a sleeve carrying a laterally project-- ing pin or pivot 41 rotatably mounted in the front end of the arm 39a of the bell crank lever 39; this pin 41 being held in position by means of a nut 41a.

42 is a rod having its up er end pivotally connected at 42 to the cran pin 21. Intermediate of its ends this rod 42 is screw threaded as indicated at 42a to receive a twopiece internally screw threaded ad'ustment nut or collar 43. 4T he rod 42 exten s loosely throu h the sleeve 41 and has a coiled spring 45, w iich surrounds the rod, interposed between said sleeve and a nut 44 at its lower end.

46 is a lock nut for the nut 44.

47 is a horizontally disposed punch-carrying head or late, detachably secured to the lower end of) the vertically movable slide 6. Projecting downward from this late 47 are a series o punches arranged Wit their axes in the arc of the circle containing the centers of the cap-receiving a ertures 25 in the dial 24, in such manner t at when the slide 6 moves downwardly, each one of the said punches will register with and enter one of six consecutive recesses 25 in the said dial. Of these punches, the iirst one on the right of the series, looking at the machine from the front, is represented by 48, it being the punch for cuttin or' striking the meta blank 48b from whic the bottle ca is formed, out of the stock or strip of s eet metal. This punch com rises a cutting lunger or head 48 of the s ape of the blan to be cut and preferably having at its upper end a iange 48a, which is detachably secured to the late 47. The head 48 is hollow and has tted snugly into it a cylinder 49 which is adapted to reciprocate vertically.

49 1s a rod extending upward from said cylinder 49 and having detachably secured to its up er end a plate 50, fitted into a vertically isposed opening 51 through the plate 47.

52 is a coiled s ring arranged in the said opening 51 and adJapted to press at its lower end against the plate 50 and to normally force tthe latter to the bottom of the passageway 51, 52 being a plate detachably secured to the top of the'plate 47 and fitted over the passageway 51 therethrough, and against which the upper end of the s ring 52 presses.

Beneath the cutting punch 48 is arranged the cutting die 53 and the guide 54 for the strip or stock of metal. rlhis guide comprises a base plate 55 preferably'arranged radially across the dial plate 24 and detachably secured at its outer end to the bed of the main frame and at its inner end to the pivot plate 23.

56, 56 are thin metallic plates arranged longitudinally, one at either side, of the guide base, 55 and having their inner surfaces spaced apart substantially the distance of t e width of the strip of metal 57 from which the blanks are to be cut. The die plate 54 is detachably secured at each side to the guide plate bed 55, it resting upon the plates 56, 56. The die aperture 53 extends through said die plate, and is `arranged to register with the cutting punch 48, and with the blank-receiving apertures 25 in theV rotary dial or blank conveyer 24.

58 indicates as an entirety a feed governing device for the strip of metal 57. Of this automatic feed controlling device, 58 is a trigger pivotally connected at 58a to a lug or u ward yprojection 58b carried by the die p ate 54. The trigger is mounted relatively oosely upon the pivot 58a, so as to be ca able of yslight lateral vibration or oscillation .at each end, as indicated in dotted lines in Fig. 5. This is preferably accomplished by having the hole through the trigger somewhat larger in dimensions than is the shank part of the pivot 58a on which the trigger is mounted. At its rear end the trigger carries a downwardly projecting' point or ringer 58 which is adapted to be projected into the plane of the path of travel of the strip 57 through the extension 54a of the die opening 53 through the die pla-tc 54. The forwardly extending arm 58 of the trio-ger carries a stud screw 58 for varying the upward throw permitted to the finger end of the trigger.

59 is a spring having one 0nd secured to the die plate 54 and its other end bearing against the arm 58d of the trigger and tending ncrmally to press the finger end 58C of the trigger toward the die opening 53. This is for the purpose of facilitating the hand feeding of the strip 57. After the cap blank has been struck from the strip by the punch 48, the

'operator presses down momentarily on the arm 58i of the trigger, and when he ceases, the linger end 58 is moved toward the die o ening 53 and will rest uponthe metal of t e strip 57 at 57 (Fig. 7), if the o erator has not advanced the strip 57. 1f e has, the nger 58c will dro into the opening in the strip from which tlie last cap blank was struck, and will permit the feed of the strip until the said finger engages the rear wall of said cap blank opening and is forced against the outer end of an adjusting screw 60 carried by a block 61, detachably secured to the die plate 54.

62 represents the second unch in the series carried by the punch p ate 47, it being adapted to enter the opening 25 in the dial plate 24 next in series to the opening 25 in registry with the die 53, and to force the metal cap blank 48", as cut by the punch 48 and die 53, to the shape shown in Fig. 12, into a die 63 carried by and inserted in the plate 22.

The punch'62 and die 63 form the blank into the shape shown in Fig. 13.

63 is an ejector for the die 63. It comprises a head 63a carried by a shank 63h, about which is arranged a coiled spring 63 c, which at its upper end bears against the eector head 63aL and at its lower end against t e bottom wall of a recess 63d in the plate 22. After the punch 62 has struck the cap blank into the die 63, the ejector 63 elevates thel blank into proper position in the dial plate 24.

64 indicates as an entirety the next punch in the series to the punch 62, carried by the punch plate 47. 64 indicates the shank of this punch 64, and 64a a head mounted to move up and down on said -shank 64 and having its lower end 64b shaped to enter a die 65 carried by the plate 22, and to form therewith into the shape shown in Fig. 14, the cap blank as delivered from the punch 62 and die l63, this operation completing the forming of the metal blank which comprises the body of each bottle cap.

v64C is an annular iiange carried by the punch head 64a above the part 64b thereon. The shank 64 of the punch is screw threaded at 64d to receive an -adiusting nut or collar 64", between which and the flange 64C, and surrounding the shank 64 is a coil spring 66 which Anormally presses downward on the head 64a. The latter is vertically slotted at 64I to receive the shank of a screw or stud 64g carried by and extending laterally from the shank 64. This connection between the head 64l and shank 64 permits the vertical movement of the former relative to the latter, while at the same time preventing rotary movement of these two elements relatively to each other. The stud 64g also serves to limit the downward travel of the head 64a under the action of the spring 66.

65' represents as an entirety an ejector for the die 65. As it is similar in detail to the ejector 63' for the die 63, further description of it is not necessary.

The next step in the formation of the bottle cap is to insert in the metallic blank, after its shaping has been completed by the punch 64 and die 65,- a disk of paper, preferably paraflined or waxed paper. For this purpose a paper reel 67 carrying a roll of paper 68, of suitable width, is pivotally mounted on a horizontal axis 69 at the front end of an arm 70 extending forward from the bed 4 of the main frame. The strip of paper 68 is preferably carried downwardly from the front of the reel 67 about a roller 71 mounted in a swinging frame 72 suitably secured at its upper end to the main frame of the machine. From this roller 71 the strip of paper is led upwardly through an o ening 73 in the pivot plate 23 and about a orizontally disposed roller 74 suitably mounted on the said plate. Thence it is carried rearwardly through a horizontally 'disposed guide 75 by means of which the paper is led above the dial 24 this guide being supported by and detachably secured to the pivot plate 23 at its front end and to the plate 22 at its rear end.

76 is a die plate detachably secured upon the guide and having through it the circular die opening 77, the center of which is arranged to be coincident with the center of each cap-blank-receiving opening 25y in the rotary dial 24 that registers with said die opening. The strip of paper 68, after it leaves the guide 75, is passed between two friction gripping and advancing rolls 78, 78'.

79 is a roc rer arm secured on the inner side of the upright 5 to the inner end of the rock shaft 40.

80 is a bearing plate or bracket suitably supported upon the main frame and extending rearwardly between theuprights 5, 5', from a point adjacent to the rear edge of the dial 24. 81, 81 are standards carried by said bracket 80, at either side thereof and on opposite sides of the path .of travel of the paper strip 68. 80' is a horizontally disposed transversely arranged shaft mounted in suitable bearings upon the said bracket 80, and carrying the paper feed roll 78'. The cooperating paper feed roll 78 is carried by a shaft 82 mounted at either endin bearings 82', 82a, carried respectively by the vertically rising and falling bearing boxes 88, 83',

mounted upon the standards 81, 81', respectively. .The feed rollers 78, 78' are normally held in forced contact with each other by means of springs 83b interposed between the At each side of its front end the bracket 8G.

supports an upwardly extending ear or lug 80h, preferably connected with the bearing boxes for the shaft 80'. Between these lugs is mounted a rocking tripper 80C, having at either side rearwardly extending lugs or projections 80d each adapted to engage the under surface of the adjacent vertically rising and falling bearing block 83 or 83'.

8O'e is a lever arm extending forward from the rock shaft 80c into the vertical plane of travel of the slide 6, or a trip carried thereby, and adapted to be engaged by the slide or said trip carried by 1t and forced downwardly, so as to cause the upward throw of the lugs 80d, 80d, consequent elevation of the bearing boxes 83, 83', and the se aration of the paper feed rolls 78, 78'. his releasing of the gripping action of the feed rolls 78, 78' on the strip of paper 68 at the time when the latter is being operated upon by the paper cutter punch, insures the pro er alinement of the paper strip between sai feed rolls at the time when said rolls are operating to feed the stripforward, since after the paper disk is cutfrom the stri the strip can right itself between the ro s 78, 78', and then as they close together and grip it, their action upon the strip will be a straight line action, and one which it has been found accomplishes the proper feeding I of the paper under all circumstances.

85 is a punch or cutter for cutting a disk of paper out of the strip 68 and inserting it into one of the formed metal caps after it has been acted upon by the punch 64. 85' is a hollow shank detachably secured in the punch head 47. 86 is a rod ittinginto said shank 85 and carrying at its lower end a circular disk 86' and at its upper end a nut 86a. The disk 86 is beveled to seat in a conical recess in thelower end of the punch. This disk, as the punch descends, first engages the paper strip 68 and rests upon it until the punch strikes out the paper disk 68', when under the action of gravity the disk 86' drops downward away from the punch and forces the paper disk into the metal cap blank beneath it.

After the insertion of the disk of paper, the formed metal cap is advanced another to it a pivot block 96.-

certain times.

dinally disposed guideway 91, which isadapted to direct and guide the disks of-cork from the magazine 88 lnto the cork-inserting mechanism 87.

92 is a reciprocatable slide iitted into the guideway 91 and adapted to engage with'the last cork disk delivered thereto by the magazine 88 and to advance it into the inserting mechanism-87 whenthe latter is elevated.

9.3 is a swinging arm pivoted at 94 to the pivot plate A23 and having slot and in connection at 95 with the slide 92.l At 1ts opposite end the arm 93 has pivotally connected 97 is a rod pivotally connected at 97 to the slide 33 and having its opposite end screw threaded at 97a and extending through a horizontally disposed passageway in the pivot block 96. 97b lare adjusting and' locking nuts n the rod4 97 for adjusting this pivot block 96 therealong and: securing it in any desired position.

Of the cork disk-inserting mechanism 87, 100 is a punch detachably and adjustably `secured at its upper end tothe punch plate 47. For the latter purpose the punch is cxternally threaded, as indicated at 100B', adjacent to said punch plate, and provided with av nut 100b for adjustment purposes.

101 is a reciprocatable cork disk-receiving head mounted on the punch 100 to move up and down therewith a predetermined disL tance in either direction while permit-ting the said punch to move up and down within it at This head is preferably formed in two sections 101 and 101, separable on horizontal linesl and having laterally, extending flanges detachably connected together by screws' 102. The upper part 101 has a hollow cylindrical upward extension 103 adapted to receive thepunch 100. The said punch is longitudinally groovedl for a portion of its. length, as indicated at 100.

103 is a laterally projecting boss'at the upper end of the part 101 of the head. Ithas a passageway 103a extending through it at right angles to the punch 100. 103b is afriction disk or plate, preferably made of some fibrous material, placed in said passageway 103a and having its inner end projecting therefrom and iitted into the-groove 100 in the unch 100. This friction disk 103b is norlmal y held in forced engagement with the ably fitted intothe outer`end of the boss 103. The frictional engagement between the said friction disk 103b andthe punch 100 is at all times suiiicient to cause the movement togeth'er in either direction of the punchV 100 and the head 101, while at the same time permitting the relative movement of the punch to the head in the event that the movement of the head is limited or sto ped. The lower part 101a of the said headD carries a downwardly projecting hollow cork guide 104, tapering both externally and internally. This taper cork guide has three vertically extending recesses 106 suitably disposed to receive the projections or lugs 48c of the cap. At its front and bottom the part 101 of the head is recessed as indicatedv at 107 to form an openin through which the cork disks are introduce into the conical passageway 104 when the said opening is in registry with the cork guide 91, as shown in Fig. 10. The ton e and groove nature of this friction control ed connection between the punch 100 .andthe head 101 insures that the said head will not turn relative to the unch, so as to throw the opening 107 in t e headv out of alinement with the cork disk guide 91, when the head is in its most-elevated position. The top plate of the cork guide 90 is bifur` cated at its rear end as indicated at 90, 90.

These arms extend out into the path of'travel of the flanged part of the head 101, with which Athey engage, as shown inl Fig. 4, t'o limit' the upward travel of the said head and the proper positioning of the cork-receiving opening 107 therein, relative to the cork guide 91.

108 is a unch detachably secured to the punch hea 47, arranged to register with the dial opening 25 next adjacent to the one be- -neath the cork inserting mechanism 87, and

adapted to force the finished cap from the dial carrier through a suitable discharge opening 109 inthe plate 22. As the caps are discharged they may be received by any suitable device for the purpose.

Iii order to prevent mutilation of either the unches or the dial carrier, should they not be in proper relative positions t'o operate correctly, asv the punches are descending, I have provided automatically acting safety clutch disconnecting mechanism, shown as an entirety at 110, on one side of the main frame.

1 1 1 is a bracket carried by the upright'5' and itself su porting the hollow vertical guides 111l an 111% 112'is a similar bracket carried by the u right 5 and having the vertlcally dispose hollow guides 112', 112g.

1131is a rod iitted'into-the guides 111" and 112 and adapted to slide up and down therein.

114 is an arm extending laterally from the slide 6 and'carrying at its outer end a vertically adjustablescrew 114 adapted to engage at its upper end with the lower end of inner end to the rod 113 and at its outer end to the rod 116, which latter rod is mounted to slide up and down in the guides 111", 112a.

117 is a coiled spring surrounding rod 113 between the guide 111 and the inner end of the strap 115. The rod 116 is of sufficient length to have its upper end 116 extend when in elevated position into the circular path of travel of the controlling dog 19 of the clutch. At its lower end the rod 116 carries an arm 118 from the inner end of which projects downwardly a rod 119. The lower end of this rod is adapted to enter a guide passageway 120 in a guide block 121 secured to the plate 22 on the main frame. The axis of this hole 120 lies in the circumference of a circle containing the axes of a series of holes 122 of equal diameter arranged near the periphery of the dial 24, and each adjacent to one of the notches 30 therein. As the slide 6 descends, forcing the unches carried thereby toward the dial plate, if the said plate is in proper position relative to the unches, the safety rod 119 will enter one of the holes 122, it being forced downward under the action of the spring 117, the upper end 116 of the rod 116 will be moved downward out of the path of travel of the clutch controlling dog 19, and the punches will operate as intended. If, however, the dial plate 24 is not absolutely properly positioned relative to the punches as the latter descend, the safety rod 119 will engage the top of-the dial plate, and the u per end 116 of the rod 116 will remain in t e path of travel of the clutch controlling dog 19 and will engage therewith and prevent the operation of the clutch to effect the downward travel of the slide 6, and the punches from being forced into engagement with the dial 24. I make no claim herein to the idea of this safety attachment for preventing the operation of the punches unless the dial late is properly positioned, as the same is t e subject matter of my patent hereinbefore referred to.

In operation, to form one complete bottle cap or closure, a strip of metal 57 is fed to the uide 54 and power applied for rotating the belt wheel 13. The foot treadle 17 is pressed downwardly and the clutch dog 15 is thrown into position to connect the fly wheel to the main shaft 8, and the slide 6 is caused to descend toward the dial carrier 24, which is in proper position to have the punches carried by the punch head 47, each enter one of a series of adjoining blank-receiving openings 25 in the dial carrier.

The punch 48 enters the die 53 and' strikes or cuts from the metal strip 57 a cap blank 48h of the form shown in Fig. 12 and the cylinder 49, under the action of the spring 52, is then forced downwardly and inserts the "fier 24 one ste said cap blank into the ca blank receivingA section beneath it. The side 6 then starts on its upward stroke and by the time the last one of t e punches or elements carried by the punch head 47 is withdrawn from the rotatable Vdial 24, the tooth 31 on the pawl 31 has drolpped into the adjacent recess 30 in the dia late and the slide 33 begins to move forward) causing the rotation of the dial car- This brings the cap blank 48b as cut by t e punch 48, under the punch 62. Again the slide 6 descends and the punch 62 acts upon'the cap blank in coperlation with the die 63. The slide 6` then starts on its upward stroke, the dial carrier is rotated one step, and the cap blank brought into proper position beneath the punch 64. When the slide next descends the punch 64 and the die 65 complete the formation of the metal cap blank. The dial late then advances the metal blank, as lmally formed one step into registry with the circular die opening. 77 and the paper disk cutter 85 descends and cuts a dis of paper from the strip 68 and the head 86 inserts it in the cap blank 48h.

Each time as theslide 33 moves forward to rotate the dial carrier one step, the swinging bar-93 forces the slide 92 inwardly and causes a cork disk 89 to be ejected from the slide 91 and introduced through the opening 107 into the head 100 of the inserting mechanism 87. When the dial carrier advances the cap blank the next step in its course'of travel after it has received a disk of paper, as the slide 6 descends, the conical projection on the cork-inserting mechanism 87 engages the metal ca blank and the punch head 100 descends an forces the cork disk through the conical passageway 104 and into the cap blank, thereby completing the bottle cap or closure. Upon the next step by step movement of the dial plate, the punch 108 in descending with the punch plate 47 forces the completed bottle cap from the dial plate 24 through the discharge opening 109 in the main frame of the machine.

I have described the course of formation and travel of but a single blank through the machine into completed form. It will be understood that in regular operation, the punches and cutters carried by the punch plate 47 operate continuously and simultaneously upon cap blanks in different sta es of formation, giving the machine a hig capacity and efficiency.

When the apparatus is operated at high speed, I have found it advisable to employ a locking pawl forthe dial plate or carrier 24, so that neither momentum of the latter nor the action of t-he pawl 31 in moving rearward along the peripheryT of the said dial, will tend to move the dial out of its proper position for any step.

123 is a bell crank lever pivotally con- 130` nected at 123 to the plate 22. One arm of said lever carries a pawl tooth 123a adapted to enter, one after another, the recesses 30 in the periphery of the dial plate 24, and the other arm 123b extends at an angle to the first one and carries a rearwardly projecting extension 123".

124 is a spring having one end secured to a plate 22, and its other end bearing against the arm 123b of said bell crank lever, and adapted normally to press the lever so as to force the pawl tooth 12311A toward the dial plate 24.

125 is an anti friction roller suitably mounted upon the slide 33 and adapted to engage with the 'said extension '123 to throw the pawl tooth 12,3 away from the dial 24. After the slide 33 moves forward a predetermined distance, `the roller 125 is carried away from the extension 123c and the spring 124 acts to set the pawl tooth 1233.

The foregoing description of a closure-making apparatus, and the drawings accompanying it, illustrate an embodiment of my invention for making a closure with a ca blank yof somewhat peculiar shape. It will be understood that the apparatus is readily adaptable for the making of closures, the cap blanks of which may be of any desired shape. Furthermore, while l have shown and described the disks 89 as made of cork, it will be readily appreciated that they may be made of any other suitable substance for the purpose. I

The strip of metal 57 employed in the machine herein showniand described, is of suiiicient width to be fed through the machine, iirst with one side uppermost and then with the other side uppermost, in order to economize material bystriking ca blanks from a single strip of metal so as to eave the blank apertures 1n the strip in staggered relation to each other, as shown in Fig. 7.
