MACHINE FOR MAKING AND .AQPILYING BOTTLE CAPS OR CAPSULES.

To all whom 'it may concern:

Be it known that I, AxEL. JuLIUs LAU-' RITS LASSEN, a citizen of the Kingdom of Denmark, residing in Frederiksberg, near Copenhagen, in said Kingdom, have invented certain new and useful Improvements in Machines for Makingand Applying Bottle Caps r Capsules, of which the following is a specification.

This invention relates to a machine for -making and applying bottle-caps or. capsules.

According to this invention the material from which the capsules are made, is introduced into the path of the stamp or press plunger in the form of plates or strips, the

stamp cutting out a disk-shaped blank, car-' rying said disk downwardly with it and finally, inclosing the mouth and neck of the bottle therewith. The three operations, viz. the cutting out of the capsule disk, the-forming of the capsule and finally the fixing of l the capsule upon the bottle, are effected by means of the same apparatus and in immediate succession, thus avoiding manipulations at diiferent places and by different machines.

When it be desired to close the bottle .by means of a material consisting of two la ers one outer la er formin the ca sule I proper and another lnner layer serving as packing or tightening means, these two layers may be simultaneously introduced terial the capsuleproper and the packing are generally cut out separately and applied one after the other to the bottle by several independent manipulations.

One form of a machine for carrying out the invention is shown in the accompanying drawings in which, Figure 1 is a sectional front elevation of themachine, Fig. 2 is a side-elevation, taken from the left-hand side, Fig. 2 a sido-ele-' vation of the machine taken from the righthand side, Fig. 3 is asectional view of the drivin gear-wheel and the clutch for coupling 1t to or uncoupling it from the mainshaft drawn on a larger scale.

adjustable in tension by means ofzthe nut. which forms one/of. its abutments. A disk} 10 of flexible material is provided between f the bottle d and the block Thesprin' place 'caps i 9 enables the machinefto bottles of different heights.

A bracket m is attached to the frame a} and carries at its upper part a plate 9 having a conical aperture, (.Fig. l) thefaxis I of which coincides with the axis of the bottle resting on the block f. .In the-said conical aperture there is fitteda plate which has also" a'conical aperturer a'n'dfl-85fli which can slide up and down on the two guide pins screwed into the plate 19.] A

clamplng ring if inserted in the top of. the

plate g incloses the mouth of the bottle to be stoppered and a die-ring a which sur rounds the ring if is located in the upper part of the plate p. Its inner edge forms the cutter for cutting the disks out of the strip n. The outer surface of the ring u is of a conical form and the ring is surbe renewed with facility when its cutting edge gets blunt. The ring '25 takes part in the up and down movementof the plate 9- remains motionless.

'The plate g is carried by twofdouble armed levers on which are rotatable about; 1105 a pivot :22 and on the front orshorter arm s.

if which rest two knife edges 3/ fixed to the. plate 9 (Fig. 2). The rear or longer arms] of the levers w are connected. at the back and attachedto an adjustable spring a. The pivot a: is not rigidly mounted in the bracket m but in supports 1 which oscillate about a fixed pivot 2. The downward x 5 rounded by a ring 'v screwed into the plate V p. This arrangement allows the ring at to];

while. the ring u, which bears on the plate p" movement of the plate 9 is limited by adjustable bolts 3, against the heads of which the projections 4 of the plate g abut. Above the bracket m is another bracket 5 in which reciprocates a cylindrical punch or stamp 6, the outside diameter of which corresponds to the inside diameter of the ring u so that the former can move through the latter. The punch or stamp 6 is so arranged that its axis coincides with that of the ring u and its throat is slightly arger than the mouth of the bottle neck. The punch or stamp 6 is fixed to a tubular rod 7 whichat its upper end carries tworollers 8 rotatable about horizontal pivots. An inwardly turned flange 9 on which is supported a tube or ring 10 of rubber or any other elastic material is provided at the lower end of the punc'h and a sliding tube 11 is fitted in the tubular rod 7 and at its lower end bears on the said ring 10 and at its upper end carries a roller 12. :YVithin the tube 11 is provided a plunger 13, the outer diameter of which corresponds to the inside diameter of the ring 10. This. plunger 13 is pressed downward by a spring 14 in the tube 11 and its movement relative to the latter is limited by pins 15 which slide in slots 16 of the tube 11. The tubular rod 7 is suspended from a chain 18 or the like which passes over guide wheels 17 and is counter-. balanced by the weight 19. v

In the upper part of the frame a there is mounted a shaft 20 carrying three cams 21, and 22 which are placed on a collar mounted on the shaft, and the first of which is adapted to actuate the roller 12 while the two latter actuate the rollers 8. Near one end of the shaft is mounted a loose gearwheel 23 and beyond this wheel a cam 24 and a clutch by means of which the gearwheel 23 can be coupled with or uncoupled from the shaft 20. At the other end of the shaft 20 there is keyed the cam 25 by means of which the feed of the strip n is eflected. During the engagement of the bolt 42 (Fig. 3) with the pin 43 during the last half of the rotation of the shaft 20, the latter is liable to be rotated too quickly especially as at this time the machine is running free and the tubular rod 7 counterbalanced by the weight 19. To prevent the over-running of the shaft and consequently the irregular operation of the machine, the eccentric portions of the cams 21 and 22 are placed diametrically opposite to the eccentric portion of the cam 24, which latter actuates a fulcrumed lever 48 controlled by spring 49 (Fig. 2). By this arrangement, which acts in the nature of a brake, the motion ofthe shaft 20 is retarded and the spring 49 set to tension, during the last half of its rotation.

The strip 1:, may be one single strip, of say aluminum or the like, or, as shown in the drawing, it may consist of two strips,

lying one on top of the other and moved along together; the upper of the said strips being of aluminum or the like and the lower of parchment or any other suitable packing material. The strips are wound on rotatable rolls 27 on a side-bracket. 26 and are fed forward by the rollers 28, 29. The shaft of the roller 28 is mounted in a frame 30 attached to the bracket 26 and the roller 29 which is covered with rubber may be moved up and down in the frame 30. The roller 29 is pressed against the roller 28 by the spring 31. The roller 28 carries disk 32 provided with the pins 33. The cam 25 is mounted on the shaft 20 above the ratchetwheel 32 and acts upon a lever 34 which is pivoted to the frame a below the cam 25, the said lever 34 being pivotally connected to a rod 35 mounted in guides and normally pressed upward by a spring 36. The rod 35 carries at its lower end a pawl 37 which on each downward movement of the said rod depresses one of the pins 33 and thereby at each turn of the shaft 20, feeds forward the length of strip required for the pro duction of a capsule. The pawl 37 is held against the pins 33 by means of a flat spring 37.

The gear-wheel 23 meshes with a gearwheel 38 which is keyed on a shaft 39 behind the shaft 20. The shaft 39 is the driving shaft of the machine and. is-provided with a pulley 40. The clutch by means of which the constantly rotating gear-wheel 23 is thrown into gear with the shaft 20 is arranged as follows: A disk 41 is keyed on the shaft 20 (Fig. 3) and has an adjustably arranged bolt 42 controlled by a spring which tends to push the said bolt toward the hub of toothed wheel 23. On the gearwheel 23 which fits loosely on the shaft 20, is a pin 43. The right hand end of the bolt 42 projects into a recess in the disk 41 and carries a roller 44. A segmental double wedge 45 is inserted between the roller and the upright surface of the recess and is connected to a s ring controlled rod 46 which is adjustable in guides and extended downwardly to the bedplate of the machine where it is connected to a treadle 47. When the treadle is depressed the double wedge 45 releases the roller 44 and the bolt 42 (Fig. 3) is moved to the left whereby its left hand end extends into the path of the pin 43 on the gear-wheel 23 so that the same now drives the shaft 20. When the operator releases the treadle 47 the double wedge 45 regains its original position and as soon as' the roller 44, rotating with the disk 41, again reaches the wedge 45, it runs upon the wedge and thereby pulls the bolt 42 away from the pin 43. The treadle is to be operated in such a way that the shaft 20 makes exactly one turn at each movement of the treadle and then stops.

" and the shaft 20 makes one turn. The

The machine. operates in the following manner that is to say, the bottle to be capsuled is placed on the block f which is so arranged that the mouth of the bottle is a little below the; upper rim of the ring t, the operator thendepresses the treadle 47 cuts a circular disk out of the strip 41- which allows the ring t under the punch 6 to give way to the pressure of the-latter. The stamped out disk moves-downward with the punch 6 between which'and the clamping ring at, which is pressed upward by the spring a, (Fig. 2) it is held securely. The

r1m ofthe bottle neck now protrudes into the hollow punch and the cut-out disk is therefore formed into a capsule on the mouth of the bottle which thus serves as the mold for the capsule. When the punch has reached its lowermost position, the disk is in the form of a capsule which fits loosely on the bottle neck. While the punch 6 is momentarily at rest in its lowermost position, the tube 11 moves slightly downward whereby it impinges against the elastic ring 10. stamp 6, the flange '9 and the. capsule is now compressed by the tube 11 and exerts pressure in 'an inward direction on the downwardly-drawn portion of the capsule. The capsule is thus pressed against the rim of the bottle-neck and into the grooves pro-. vided on the bottle-neck, that is to say, it

is securely fastened around the bottle neck,

During the further rotation of the shaft 20 the punch 6 and tube 11 are lifted by'means of the weight 19, while the spring controlled plunger 13 prevents the bottle from also rising. During the upward movement of.

the plunger the length of strip n required for the production of the next capsule is moved forward and when the shaft 20 has completed a whole rotation. the machine automatically stops working.- The stoppered bottle can now be taken away and another put in its place.

The position of the parts in Fig. 4 corresponds to the position of the parts shown in Fig. 1. In Fig. 5 a disk is cut from the strip n and the formation of the cap is commenced inasmuch as the circumferential portion of the same is shown as being.

so that the elastic ring 10 is pressed together The latter, which bears against theand forced toward the cap so as to press it into the grooves ofthe bottle-head. Figs. 8 and 9 show the position of the eccentric cams 21 and F ig.' 8 shows the position of the cams when the parts are in the position shown .in Figs. 1 and 4, while Fig. 9

shows the position of the cams when the parts'are in the position shown in Fig. 7

From the foregoing description it is obvious that in the present machine thereare three operations, namely, the cutting of a.

disk-shaped blank from the capsule material, the formation of the capsule, and its attachment to the bottle-neck by means of the operative parts described, these operations taking place consecutively and being initiated by the depression of the treadle 47 and the coupling of the clutch and gearwheel to the driving shaft.

Having thus described my invention, I claim as new and desire to secure by Letters Patent:

1. In a machine of the kind described, the combination of, a cutting die adapted to receive a strip ofmaterial thereon, means.

for holding a bottle'with its mouth in said die, a punch adapted to pass through said a tubular punch adapted to be forced through said die, a clamping means held yieldably in said die and against said punch as the punch is forced through said die, a capsule compressing means in said punch, and means for reciprocating said punch relative to the die. v

3. In a machine of the kind described, th combination of an annular cutting die, means for holding a bottle with its mouth coaxial with said die, a tubular cutting punch adapted to be pressed through said die to cut a capsule blank and force the same over the mouth of the bottle, a clamping ring yieldably pressed in said die and against said punch and adapted to clamp said blank against said punch while the blank is being forced over the mouth of the against said punch and adapted to clamp said blank against said punch while the blank isbeing forced over the mouth of the bottle, an elastic tube in said tubular punch, means for pressing the ends of the elastic tube toward each other to cause the elastic tube to press the capsule into en agement With the bottle-neck, and means or recipriocating the tubular punch relatively to the 5. In a machine of the kind described, the combination of a suit-ably supported die, a clamping ring yieldably held in said die, means for holdlng a bottle with the mouth thereof coaxial With said die, means for feeding strips of material over said die and -mouth, a tubular punch adapted to be forced through said die-and against said clamping ring and having an innerannular flange, an elastic tube in said punch and resting on said flange, a sliding-tube in said unch and bearing against the upper end 0 said elastic tube, a spring-pressed plungenin said sliding tube, means for reciprocatlng said punch relatively to said die and means for reciprocating said sliding tube relatively to said punch.

In testimony, that I claim the foregoing as my invention, I have signed my name in presence of two subscribing Witnesses.
