In the embodiment of the invention illustrated theoperative mechanism issupported upon a table T mounted adjacent opposite ends upon standards S; Apair of rails 15, 16 is mounted upon the table to extendlongitudinally of and-in spaced relation to thetable by means of brackets D of arch form, each of said rails constituting the outer member respectively .of channels A, B,

and an intermediate rail 17 constituting the .other'member of said channels, the edges of said channel rails being preferably beveled to incline in a direction from the top into' the channels, as at 18, for the enga ement of and serve as supporting ledges orthe laterally extending portions of corrugations or rufiies arranged at the margin of the flanges of closure caps C with the cup por-.

tion of the caps extended into or through the channels.

Means are provided to intermittently advance the caps predetermined distances along said channelsrand to feed caps to one in the di-rectionv indicated by the "arrow in Figure 1 and in a plane with the end 'of the channels. For this purpose there is providedv at the one end of the channels,'

constitutin the entrance ends, a disk or table 19 fixed to a vertical shaft 20 to rotate therewith in a horizontal [plane channel rails, said shaft being. rotatably the ures are contained in a hopper (not shown) from which they are delivered to the disk- 19 bya chute25 (Figure 1) leading from the hopper to the disk, the caps as they are discharged from the chute being positioned by the rotation of the disk in alined relation with the leading cap in-engagement with a stop 26 (Figure 3) fixed to and constituting a part ofa guide plate hereinafter deplungers 27, with the .-cap succeeding thev leading cap in line with. an extension 28 of the intermediate channel rail 17. The plungers 27 are slidably mounted in slideways in a shelf 28 (Figures 3 and 4) carried by posts 29 fixed to and extending upward from the table T with the shelf extending over .andspaced from the cap reteiving disk 19,

the plungers being retained in-the slideways by shouldered studs 30 to which the plungers are fixed, the studs being extended through scribed, and said leading cap and the alter- .nate cap positioned. at the entrances to the channels A, B and inlinewith a pair of Figure 15 is a plan view, on an enlarged slots in the shelf and plates 31 fixedto'the shelf, the plungers being yieldinglyurged in a direction to deliver the leading and alposed relation to the plates 31; The plungers are positioned against the force of the springs 32' to permit of the closure caps being positioned by the disk 19 between the ends of the; plungers and the entrances to the channels by a-block 34 extending transversely of the plates 30 and for wardly of the abutment plates 33', and'mounted on a slide 35 mountedin. a" slideway in the shelf 28 in interposed relation to the plungers 2'7 by the reduced end of a stud 36 (Figure 4) extended above the block and through a'slot in an arm 37 fixed to a stud 38 rotatably mounted in a perforation of a boss ofshelf 28. 'The arm 37 is actuated to movethe plungers to the position shown in Figure 3 and moved in a'direction forwardly thereof to permit the plunger to have cap feeding movement imparted thereto by .the springs ternate caps from the cap receiving disk into the. channels by springs 32 connected to the arm carrying'stud 38, with the bar 40 by meansof an arm 41 fixed to said bar and connected by a link 42: with an arm 43 fixed to stud 38 and extending below the disk 19.

To guide and positionthe caps delivered by in the plane of the shelf 28 to the channel rail supporting bracket D shown in Figure 3, the underside of said plate 01 being arranged with a guide ledge f in line with the chute 25 by providin the plate with an undercut portion, and t e stop member 26 being secured to said undercut portion of the plate at the end opposite. to the juncture thereof with the ,chute 25. 1

The bars 39, are arranged below the channel forming rails 15, 16 and have elon-.

gated plates 44, fixed thereto with a mar ginal portion in interposed reIation to the bars and said channel rails, the plates being of greater width than the bars and the marginal portions opposite to that at which they are securedto the bars extending beyond the one side of the bars and arranged with equidistantly spaced fingers 46, the spaces between the fingers being slightly greater than the diameter of the closure caps.- The bars 39, 40 are supported adjacent opposite ends by pivotally connecting the same to disks .48 (Figure 11), as at 47, (Figurel) eccentric to the axis of said disks, and the disks are fixed to the upper ends of vertical shafts 49 rotatably mounted in bearings in brackets 50 supported from the underside of the' table T, the shafts being rotated in synchronism by bevel gears 51 on said shafts meshing with bevel gears 52 on shafts 53 journaled in bearings in the brackets 50 and driven from the drive shaft 21 by a gear 54 on said latter shaft meshing'with pinions 55 fixed to the shafts 53. The eccentric connection of the bars 39, 40 with the shafts 49 is such that the finger plates will be moved simultaneously laterally of the channel rails 15, 16' and out of the channels A, B, then longitudinally in a direction toward the cap receiving disk 19, then laterall into the channels to engage the fingers o the plates 44, 45 in the rear of successive caps supported in the channels, and then forwardlyof the cap receiving disk 19 to advance the caps in the channel's, when the sequence-of operatio'n is repeated. B of the actuating arm 37 or the cap feeding plungers 27 with the one bar 40 said plungers will .be operated in timed sequence with the finger plate carrying bars to deliver caps. from,. the diskv 19 to the channels during the period that the finger carrying plates are moved out of the channels and retrograde movement is being impartedthele' to in a-directiontoward the cap receiving disk 19. I, i

As the caps are advanced along the channels they are su'ccessively positioned relative to mpans for supplying an adhesive to the 7(3 of a slide 74 slidably mounted on a the connection caps to secure sealing padslor disks therein. This adhesive is carried by websin a non-viscid state by coatingor impregnatin the webs with the same, dlsks being severe from the webs and deposited in caps in the channels. For this purpose a pair of rolls of adhesive carrying webs W are rotatably supported upon a shaft 57 carried by arms 58'extending laterally from a bracket 59 mounted upon the table T to extend trans"- versely above the cap receiving channels ad jacent to the entrance ends thereof (Figways 60 in the upper surface for t e webs and the guideways having openings 61 there- .ures land 7), said brackets havin guidethrough, one in line with-the channel A and the other in line with channel B, and rela i tive to which openings unches 62 are vertically movable to cut and deposit't-hem in caps positioned relative thereto in the channels. These punches are threaded into a head 63 and secured in adjusted position by lock nuts, as shownv at 64, the punches slidably enga ing openings in a'block 66 fixed upon the racket 59 to guide the same to the openings in the web. guideways. The punch carrying head 63 is mounted to'have vertical sliding movement and is reciprocated m'timed sequence with the advancing of the caps in the channels by rods 67 fixed to the headand extended through the channel rail 17 and table I (Figure 5) and conne cted below the table to a head 68'having a pivotal connection with an arm 69 extended laterally from a collar or tive to the punches bv feed fingers in the form' of blocks 71 loosely mounted on a rod 72 extending transversely above the guideways and fixed in upwardly extending arms of the bracket 59 extended laterally of the table T, the web engaging portion of the blocks being preferably arranged with a friction member, such as a-rubber block 71 (Figure 6), and yieldingly urged into en-- gagcment with the webs upon the uideways by springs 75, the webs being gui ed to said feed fingers between oppositely flared guide plates 75 fixed to the bracket 58. The feed .fingers are reciproeated from an eccentric 76 fixed to the drive shaft 21 (Figure 5) having a strap'or collar 77 encircling the same connected with the s lide 74 by a lever 78 pivotally supported by an arm 79 extended laterall and downward from the bracket, 59, sai lever havingv a bifurcation at one end for engaging a r0180 fixed in ears of the slide 74, as at 81 in Figure 5. The other arm of the lever is adjustably connected with the eccentric strap 77 by a rod 82. To prevent retrograde movement of the webs bythe return movement of the feed isks from the webs 7 part I fingers pawls 83 are loosely mounted on a rod 84 fixed in brackets 85 mounted upon bracket 59, said pawls having plates 86 fixed to and extended be end the pawls with the extremities serrate and adapted to'engage upon the webs in the guidewa'ys. The pawls are retained in position with the serrated plates engaging the webs by weights adqustably mounted on pins fixed in and ex- .tending forwardly of the 'pawls, as at 87 in Figure 7. The pawls are arranged on the rod 84 to rest upon the webs at an angle inclined forwardly to the vertical, and as the webs are advanced by the feed fingers they will readily pass below said serrated plates.

However, should return movement be imparted to the webs such movement will cause the serrated fingers to forcibly impinge against the webs and hold them against movement.

Means are provided to render the feeding fingers inoperative to feed the webs should there beno caps positioned relative to the punches. For this-purpose latches 88' are pivotally supported in blocks upon the bracket 59 to have movement in a direction toward and away from the feed fingers and finger pins 89. The latches are acap into and out of the path of movement of pins 89 extending laterally from said fingers, the latches having a weighted lateral extension 90 to normally move the latches to position out of'the path ofmovement of the ositioned for the supporting and riding o the feed finger pins thereover and thus hold said fingers out of engagement with the webs on the guideways by means controlled by caps positioned in the channels, and comprises a pair of weighted levers 91 pivotally mounted on opposite sides of the bracket 59, one

arm of the levers extending belowthe extensions 90 of the latches and carrying a set screw 92 forthe engagement of said latch extensions. The feed finger 71" feeds the one web to the punch positioned relative to the channel A, and the weighted end of the lever 91 for actuating the. latch 88 associ ated with said feed finger terminates in line with the channel A and is arranged with a weighted contact piece 91 (Figures 5 and 6) or engagement by caps advanced along thechannel A, and as said contact'piece is engaged by a ea it will lower the end of the lever engage below the latch extension 90 permitting the latch to move laterally out of the path of movement of 'the pin 89 carried by the feed' finger and permit the finger to be impinged against the web by its spring -7 5 during the feeding movement thereof and feed the web to the punch. However,

should there be no cap in the channel A,

relative to the weighted end of the lever and thus said end of the lever unsupported by in the channel the lever will move downwardly an'd elevate the opposite end of the lever en aging the set screw92-carried thereby wit the latch extension '90 and move the latch into the path of and for en gagement by the feed finger pin 89 and thus support the feed finger 71* out ofcontact with the web and render the sameinactive to feed the web during the movement thereof.

To actuate the latch 88 to render the other feed finger 7 1 inactive a contact piece or finger 94 is fixed to and extends laterally from a weighted lever 95 pivotally supported on the bracket 59, as at 96, the contact piece being arranged to extend longitudinall of the channel B and positioned in the path of movement of caps advanced along said channel. Should there be no cap in the channel to engage said contact finger 94 the free. end of the lever 95 will ,move downward moving with it the end of lever 91 to an extension of which lever it is con-- nected by a rod 97 .(Figure 7) moving the latch 88 associated with the feed finger 71 to position for engagement with the pin 89 carried by said feed finger and maintain the latter out of operative relation to the web. \Vhen the contact finger 94 is again engaged by a cap in the channel B the lever 95will be rocked to move the set screw carrying end of lever 91 to permit the latch 88 to move out of the path of movement of'the pin 89 of feed finger 7.1 and thus rendering the same active to feed-the web upon the actuation of said finger. It will be obvious that by the mechanism ,described that either of the web feeding means is rendered inactive should there be no cap in the channels to be positioned to receive disks severed from the webs ,by the punches and that such'condition of the mechanism will be maintained until there are caps in the-channels to receive disks severed from the webs.

- The caps are advanced in the channels from the adhesive supplying means to means to deliver sealing disks or pads of suitable material, such as cork, to the caps. For this purpose sealing disks in stack formation in tubular chutes 99 are supported upon members 100- mounted on the table T to extend transversely above the channels from opposite sides ofthe table in line with slideways 101 in said members, the tubes being fixed at the outer sides of the channels in ,blocks 102 fixed upon said members 100 with ers. The ejectors are actuated by slides 105 also slidably mounted in slideways in the members 100, said slides being reciprocated by levers 106, pivotally carried by supports 107 for the members 100 and the levers rocked to move the slides toward and away from each other in synchronism with the movement of the cap advancing finger bars 39, 40, by a pair of eccentrics108, 109 operatively connected with the levers by straps embracing said eccentrics (Figure 11) adjustably connected by rods 110 with the levers 106. As the slides 105 are moved toward the channels a shoulder of the slides engages with the'ejector plates and im arts disk engaging movement thereto, an turn movement is imparted to the ejectors by latches 1-11 pivotally carried at 112 on the ejectors engaging the rear of the slides 105. To prevent actuation of either of theejectors and the ejection of sealing disks from the stacks should there be no caps in either of the channels to receive such disks means are provided to render said ejectors' inactive. This means comprises levers '113 pivoted to the side of the members 100, the one arm of the levers being weighted'and arranged to extend over the channels and having a-contact piece 114=secured thereto adapted to engage in the path of movement of the caps in the channels, the levers being moved forengaging said contact piece in the paths of movement of the caps advanced in the channels for contact by said caps by gravity and the influence of springs 115 seated in a re-' ccss in the members 100 and engagingbelow v the extended ends of members 116 fixed upon the latches 111 extended below and with which the ends of the levers 113 opposite to the contact pieces engage, said sprin s also serving to move and maintainthe atches 111- ont of operative relation. with'the slides 113. With caps in the channels the contact pieces 114 will be engaged by said caps as they approach the sealing disk feeding means moving the levers against the force of gravity and the influence of the springs 115, and through the engagement of the levers with the members 116 will position and maintain the latches in operative connectionwith the slides; 105 to impart return movement to the ejectors. However, should there be no caps in the channels the weighted ends of the levers will drop "into the channels moving the opposite ends away from the latchmembers 116 and the springs 115 operating to move the latches 111 out of engagement with the slides 105 releasing the ejectors therefrom. Y

, The plungers 104 are carried by a head 117 slidably mounted at opposite ends in uprights 118 fixed in and extending upward from the table T and connected at the upper ends by a crossbar. The plunger carrying head and the e y the plungers a e e pros re- I cated in timed sequence with the advancing of the caps inthe channels and the delivery of sealing disks to the plungers by the ejectors by an eccentric 119 on the shaft 21 connected with the plunger carrying head by an' arm 120 extended laterally from a strap 121 encircling the eccentric 119 and pivotally connected with a head 122 below the table '1 connected with the plunger carrying head 117 by rods 123 extended through openings in the table.-

During the interim of the movement of Y the caps in the channels from the supplying of'the adhesive carrying disks thereto and to position for supplying sealing disks or pads to thefcaps the adheslve is rendered viscous by passing the caps with the adhesive carrying disks therein through a zone having an elevated temperature by passing the caps over the flames from gas jets provided by perforated pipes 124 connected in a suit able manner wlth a source of supply.

The caps with the sealing disks assembled therein are delivered from the channels to means to place the sealing disks under pressure during the period of cooling or congealing of the viscous rendered adhesive. For this purpose there is provided at the delivery ends of the channels a head mounted on the table to rotate about a vertical shaft 125 fixed in the table and an arm 126 fixed to the end of the table and extended upward and in overhanging relation to the table. The head has an anti-friction support upon the table T comprising balls engaging 1n raceways in rings fixed upon the table and to the bottom of an annular shelf or table 130 constituting a part of the head, as at 1 14 in Figure 2. 'The head is rotated by a pinion 127 meshing with a gear 128 constitutinga part of the head, the pinion being driven by a bevel gear onshaft 21 meshing with a bevel gear fixed to the shaft of pinion 127, as shown in dotted lines at 129 inFigure 1. The shelf or table 130 is in a plane with but slightly belowthe plane of the channel rails to receive the caps as they are delivered from the channels. Two concentric rows of plungers 131, 132 are slidably mounted in openings of rings 133 forming apart of the head arranged in supervised and spaced relation to the shelf and one ment. of the sealing disks therein by the said cam plates of rollers mounted on studs extending laterally from the plungers, as

shown at 138. The cam plates are mounted in superposed relation on posts 139 fixed ina bracket 140 mounted upon the table T to have adjustment relative to the plungers by engaging the reduced ends of the posts in slots in the cam plates, as shown at 1 11 in Figures land 2. The plungers of the inner row are of greater length than the plungers of the outer row and extend above the same, and the cam plate 136 is arranged to extend beyond the cam plate 137 for the engagement of the rollers carried by said inner row of plungers, and the cam plate 136 being of less length than the cam plate 137. The cam plates are secured in adjusted position by nuts threaded onto the mounting posts 139 and the rotation of screws 142 rotatably mounted in and held against longitudinal movement in an extension 1 13 of the bracket 140 and having threaded connection with ears extended laterally from the cam plates, as clearly shown in Figures 1 and 21 The caps with sealing disks assembled therein from the channel A are positioned on the shelf relative to the inner row of plungers 132, and for this purpose the channel rail 15 is extended over the shelf to a position slightly beyond the inner row of plungers 132 (Figure 15), and has a plate 145 fixed thereto to extend slightly over the beveled edge 18 of the rail to engage a marginal portion of the cap flange and retain the cap in position on the rail. A finger 146 delivered from the channel at the marginal ortion opposite to the engagement thereof y the rail 15, and thus co-operate with the plate 145 to position a cap in line with a plunger 132 for engagement by the plunger as it rides oil from the cam plate 136. .As the cap on the shelf is engaged by a plunger and is moved with the plunger and shelf by the rotation thereof it will move the finger 146 against the tension of the spring 147',

and as the finger. rides oil from the cap it will again be positioned relative to the stop pin 145 by said spring.

To position caps dehvered from the chanmes es nel B relative to the plungers 131 a finger 1 19 is fixed upon the channel rail 17 to extend beyond'the end of said rail withthe extremity curved in a direction into the channel, as at 150, said finger having a groove in the edge in line with the bevel edge of the rail 17 and cut through the curved extremity for engagement of the marginal portion of a ca The cap is retained in position relative to the plate groove by a finger 15 1 pivotally mounted at one end on the plate 149 and urged in a direction toward the channel rail 16 by the spring 147- to position a roove extended about the side and ends 0 a protuberance at the under side of the outer end, of the finger, similar to the protuberance on the finger 146, as at 151; in line with the heveled edge 18 of rail 16 and in opposed relation to the groove in the plate 149 for the engagement of the marginal portion of a cap as it is delivered from the channel and thus position a cap delivered from channel B on the shelf relative to and for engagement by a plunger 131 as the plunger rides oil" from the cam plate 137. As the cap delivered from the channel Bto the shelf is engaged by a plunger it is moved with the plunger and shelf by the rotation thereof moving the Finger 151 against the tension of the spring 147, and as the finger rides off from the cap it will again be positioned relative to the stop pin 152 by the" spring 147. To permit the finger to move sufiiciently for the passage of the cap on the shelf the end of the rail 16 in the rear of the cap supporting edge is cut away, as

shown at 15'.

As the plunger rollers 138 ride up the cam plates to position the plungers away from the shelf and release the plungers from the closures upon the shelf an ejector bar 153 intersecting the row of closures positioned on the shelf relative to the plunger-s 132 isengagod by said closures and along which bar such closures are moved by the rotation of the shelf with the head to eject such closures from the shelf, said ejector bar being fixed to a bracket 154 fixed to the cam, plate carrying bracket 140. The closures positioned on the shelf relative to the plungers 131 are ejected by a bar 155 carried by a plate 156 fixed upon the bracket 154 to extend above the' ejector bar 153 whereby the closures ejected by said latter bar may pass below said plate.

The apparatus is driven from a shaft 157 journaled in hangers 158 suspended from the under side of-the table T and said shaft connected with; the drive shaft 21 by bevel gearing 159. The shaft 157 has a pair of pulleys thereon, one of which is fixed and the other loose to belt drive the shaft from a suitable source of power.
