machines for assembling the several parts 'of a bottle closure, or similar article, said parts consisting usually of a metallic cap, a sealing gasket or packing, and a cementingmedium interposed between the cap and gasket, and the object of my invention is to furnish an improved machine for accomplishing this end in .an expeditious, economical and satisfactory manner.

In the accompanying drawings forming part of this specification and in which similar letters of reference indicate similar parts throughout the several views :-Figure 1, is a plan of my improved closure assembling machine: Fig. 2, a front elevation of the ma chine; Fig. 3, a section of Fig. 1 on line AA; Fig. 4, a vertical sectional elevation through the punch for cutting the fusible disks used to cement the gasket to the metal cap showing, in section, the rollsfor guiding and for feeding the strip of material from which said disks are'punched and the roll for carrying away said strip after being punched; Fig. 5, a section on line BB, Fig. 1; Fig. .6, a plan of the device for rendering the punch inoperative when the cap carrier fails to carry a cap to a point beneath said punch; Fig. 7, a side elevation of part of Fig. 6; Fig. 8, an end elevation of the front end'oft-he machine Fig. 9, an end elevation of the rear end of the machine} Fig. 10, a plan of a cam for operating the punch for cutting fusible disks; Fig. 11, a-

, plan of the gasket feeding disk and of part 45 of the notched disk for holding the gasket; Fig. 12, a bottom view of the cam for actuating the fingers of the gasket carrying disk; Fig. 13, a side elevation of a' finger carried My machine consists of a feeding device for carrying the metal caps of the closure to a constantly rotating wheel or table, of a means for placing a disk carrying, or conslsting of, a fusible cementing medium in said caps while carried by said wheel or table without retarding its revolution, of a means for transferring said caps carrying the cementing medium from said first wheel to a second rotating wheel or table, inheatmg said caps while in said second wheel sufficiently to fuse the cementing material, in transferring said caps while still hot to a third rotating wheel or table, in placing in said caps, over the fused cementing material, while in said third wheel a gasket, in applying pressure to the tops of said gasket while being carried around in said third wheel and finally in removing said caps from said third wheel after the gaskets have been 3 is the main driving shaft furnished Withsome means for driving, the usual fast and loose driving pulleys 45 for instance. Upon shaft 3 is a. miter gear 6 which meshes with and drives a miter gear 7 which carries and drives a sleeve 8 which carries a. spur gear 9. The gear 7 and sleeve 8 are carried by a stud 10 which is carried by the table top 2. The gear 9 meshes with and drives a gear wheel 11 the hub of which carries a gear wheel 12. 13 is a stud, carried by table top 2, upon which gear 11 is carried. Gear 12 meshes with and drives a gear 14 which meshes with and drives a gear 15 which meshes with and drives a gear 16. All of these gears being shown best in Figs. 2-and 3.

diameter and all rotate at the same speed.

17 is a flanged pulley carried on shaft 3 I which is connected by a belt 18 with a horizontally disposed pulley 19 which is attached to a suitably carried vertical shaft 20 the upper end .of which carries a revolving feed disk 21 the top of which is covered, or

partly covered, by a cover plate 22 inthe usual manner. The feed disk 21 is driven at a high speed. The empty caps are placed upon a feeding table 23 and pass in between the cover plate 22 and the top of the revolving feed disk 21 and are carried to a rotating wheel or tab1e24 which is carried upon the upper end of shaft which carries and v is driven by the gear wheel 16 before referred been placed in the to. The arrangement and operation of the feed disk 21, being well known, will not need detailed description. The caps being carried by the rapidly revolving disk 21 into the pockets 26 in the periphery of the more slowly moving wheel 24 are carried around in these pockets and presently pass under a punch 27, Figs. 1, 2, 3, 4, 6, 7, and 8, which the rod 29 in engagement with cam 28. At

its upper end the rod 29 carries an arm 33 which carries the punch plunger 34 which operates vertically in aguide 35 which is carried by a frame 36 carriedby the table top 2 as best shown in Fig. 4. The male part of the punch is carried or formed by the lower end of plunger.34, and the female part 37 by the frame 36. The male part ofthe punch being substantially of the same diameter as the interior of the'metal cap, and these caps being carried around under the punch by the constantly moving wheel 24, it would be practically impossible to employ the punch itself to carry the punched disk to the interior of the cap'as the latter would certainly engage the side of the former before it could'be withdrawn. In order that the punched disk may be placed in the cap without danger of improper contact of any of the parts of the machine, I bore out the lower part of punch plunger 34 and place loosely therein "a feeding rod 38 which is slotted at 39 for a 'pin 40 which limits its vertical movement. The rod 38 is supported by the strip of fusible material before it is punched but as soon as the punch cuts a disk,- the rod 38, resting on this unsupported disk, dropsand by its weight carries the disk to the cap. The disk'having lower end of rod 38 is above" the level of the strip of fusible material when the mechanism feeding this tothe punch presently carries it under the punch when this latter is' again operated. At this. timethe wheel 24 has carried another cap under the punch-and the operation above described is repeated.

It may sometimes happenthat one of'the pockets of the wheel 24 willpass the feeding plate without receiving-a cap and in this event it is important that the punch 27 fail to operate, for if it did the fusible disk Figs. 1, 4 and 8.

cap, the cam 28'li fts. the rod 29 and connected parts until the would drop. into the pocket and would probably adhere to the outer side of a cap subsequently carried by this pocket and would cause trouble whenthe cap was heated. In

order to prevent the operation of the punch and the cutting of a fusible disk for an unoccupied pocket of the wheel 24, I employ a finger 41, Figs. 6 and 7, which is secured to the lower end of a vertical shaft 42 carried in suitable bearings forming part of the guide 35 of the punch plunger 34. The upper end ofshaft42 carries fixedly an' arm 43 which carries an upright stop 44. The l I 'outer end of finger 41 is engaged by the sides of the caps 45 carried in pockets in wheel 24 or by the partitions 46 between these pockets. If it should happen that a pocket does'not carry a cap the outer end of finger 41, when it reaches this capless pocket, will be unsupported and a spring 47 will pull the outer end of arm 43 in between the top of the guide 32 and the arm 33, carried by the top of cam rod 29, and will prevent the falling of arm 33 and the operation of the punch to cut a disk for the particular pocket of the wheel unoccupied by a cap. As the wheel revolves the end of finger 41' is presently on gaged and moved out by the partition at the rearside of the unoccupied pocket and moves the stop 44 out from under arm 33 when the mechanism actuating the punch again is free to operate.

I prefer to form the disk of fusible material. I carry this strip upon a roll 48,

I From roll 48 the strip .terial, which is to cement the cap and gasket together, from a narrow strip of the mapasses downunder a guide roll 49, thence between drawing rolls 5051, under the punch, and over a driven roll. The drawing rolls are connected by gears 52-53 and the shaft of one of these rolls carries a bevel gear 54 which isdriven by a bevel gear 55 which is carried on a shaft 56 which carries a spur gear 57 which meshes with and is driven by the spur gear 16 which drives the wheel 24.

The feeding of the strip 58 of fusible ma terial from which the disks are cut" is constant'and when thepunch is in contact with i.

up'fbetweenthe feed rollers 50-+51 and the punch but there being some considerable stiffnessto this strip it straightens out as soon as'released by the punch being lifted this strip it is moving forward and buckles and no harm results. After leaving the punch the then. perforated strip passes over a roller 59, which I prefer should be positively driven at a considerable speed, to as-.

si'st the passage of the perforated strip away from the punch. 'To drive roller 59 I place .upon its shaft a pulley 60 and connect this pulley toa pulley 61, carried by the main shaft 3, by a belt 62. The caps having the fusible disks placed in them are carried around by the wheel 24 until presently, one

the pockets 26 as shown in Fig. 1. The r-.

tation of wheel 24 moves the caps along the shifter 65 until they enter pockets 66 formed in periphery of wheel 67 which is carried on and driven by shaft 68 of gear wheel 15 at the same speed as wheel 24. Beneath 'the wheel 67 is a heating device to fuse the disks in the metal caps; the heat being preferably applied to the under side of the wheel, and in order that the heat may reach the caps thebottom of pockets 66 are perforated as shown at 63, Fig. 1. I prefer to use gas as the heating agent which is conducted to any suitable form of burner by a pipe 69.

64 is a pipe for a pilot light which burns when the main burner is turned out.- As this construction is old it will not need elaboration.

Heat from the wheel 67, or the burners for heating this wheel, is very apt to be carried to the wheel 24, where it is not wanted, and perhaps to the punch, where, owing to the nature of the fusible material, it would be fatal, and in order that this wheel and punch may be kept cool I place under the wheel a tank 70 which is kept supplied with cool water and I furnish the under side of the wheel 24 with a flange 71 which enters the water in tank 70. This arrangement I find suflicient to prevent danger of heating parts which shou d be kept cool. The caps having been heated and the disks fused while in wheel 67 are, when this wheel in its revolution brings them to a shifter 72, similar in arrangement and operation to shifter 65, switched from pockets in wheel 67 to pockets in a wheel 73 where they receive the gaskets andwhere pressure is applied to the top of the gaskets until their adhering to the caps is assured. The wheel 73' is carried upon, the shaft 74-which carries the gear 14 and is driven by the rotation of this gear at the same speed as the wheels 24 and 67. Beneath the wheel 73 and fast to and driven by shaft 74, which carries and drives this wheel, is a gear 75 which meshes with and drives a gear wheel 76, Fig. 5, which is fast to a sleeve 77 which rotates around a spindle 78 projecting up vertically from table top 2. Fast to top of sleeve 77 is a plate 79 the periphery of which is. furnished with ockets 80 and with radial slots 8-1 for carrying fingers 82 which are furnished with upwardly projecting pins 83 which rest in a cam groove 84 formed in astationary casting 85 which is carried by the frame 86 carried by plate 2, see Figs. 5, 11 and 12. is the plate 9 revolves it causes the pins 83 on the fingers 82 to travel around in the cam roove 84 andthe fingers are thereby moved 1n and out in slots 81 in plate 79. Pivoted to the circular disks of cork.

.half grasped by each one.

center of the casting 85 is an arm 87, Figs. 1, 5 and 11 which carries a tube 88 which carries a stack of gaskets, in most cases thin In its operative position the tube 88 registers with a perforation 89 in a plate 90 which covers the outer part of the plate 79 and with the pockets in.

the periphery of plate 79 when these pockets are by the revolution of the plate brought successively beneath it.

The plate 79 is carried in a depression formed in the top of frame 86, this depression being of somewhat greater diameter than the plate and forming a runway 91 for the disks or gaskets as they are carried from the tube 88 to the caps.

The arm 87 may be moved around its center and over the plate so as to move the tube 88 out of register with the perforation 89 in plate 90 when it is desired to cut off the feeding of the asket to the plate 79. The arm 87 is fllI'l'llSllBd' with a erforation 92 which may be brought in register with perforation 89 when it is desired to have access to this latter perforation for any purpose. In Fig. 11 a plan of the plate 79 is shown and from this figure the positions of the several fingers 82 in relation to the runway 91 will be seen. These fingers not only push the gasket along the runway but also sweep this runway clean during their passage of any particles of cork or other material which might presently interfere with the proper working of this part of the machine. The plate 79 and the fingers 82 carry the gaskets around until the pockets 80 in this plate are directly opposite pockets 93 which are carried in a circular plate 94 which substantially engages plate 79 and which is carried by and turns with the shaft 74 which is driven by gear 14 which drives the wheel 73 which carries the caps to receive the gaskets. The pockets 93, in plate 94, which are semi-circular, are placed directly over the pockets in wheel 7 3 and when the pockets in plates 79 and 94 are in register the gasket is held between them being The plates 79 and 94 are at a somewhat higher level than the tops of the caps carried in wheel 73 and when the pockets in plates 79 and 94 are in register the gasket is engaged by a plunger and driven out from between these plates to a cap as follows.

Carried by the shaft 74 is a head 95, best shown in Fig. 5, which is furnished with as many vertical guides 96 as there are .pockets in the wheel 73, each pocket having a guide directly over it. Each pocket carries a plunger 97 and a spring 98 for forcing said plunger downward. In its lowest position the lowerend of a plunger bears against the top of a gasket and holds it againstthe disk of fused material carried in a cap, but should there be no gasket in the cap, the lower end of the plunger will not fall sufiiciently far to touch the fused material, if it did this sticky material adhering to it would cause 4 no end of trouble until removed. The fall of the plungers is regulated by a hardened steel collar 99 interposed between the tops of the guides 96 and a collar 100 carried on the upper end of the plungers.

-101 is a stationary semi-circular cam at the top of head 95 the front end of which 7 1s beveled, as at 102 and the rear end of which is abrupt, as at 103. As the casting 95 is revolved the collars 100 on the plungers 97 are brought successively to the beveled front end 102 of cam 101 ride up this bevel,

which lifts the plungers from the gasket in the cap, and travel along the flat top of the cam until they reach the abrupt end 103 when theyare dropped. At the point where the plungers are dropped they are directly over the gasketcarried by the plates 7 9 and 94 and the falling plunger drives them out 1 from between these plates and seats them upon the fused cementing disk carried by the hot caps carried in thepockets in wheel 73. The plungers having driven the gaskets v to the caps remain in contact with and press them down, until the revolution of the machine brings the collars 100 to the beveled front end of cam ring 101 which lifts the plungers as before described and holds them above the caps so long as the collars 100 are in contact with ring-cam 101. During this tlme the caps are removed from wheel 73.
