BOTTLE-SEALING- MACHINE;

Patented Nova 18, 11913,;

Tol'l ll tolwm it me concern:

Be it flown t at l, Anos Con, a citizen of the llnited States, residln at a Brooklyn in the county ot Kings and tate lib of New horlr', have invented certain new and useful provements in Bottle-Sealing Machines, of which the following is a specitication.

This invention relates to bottle sealing machines in which the sealing operation-is accomplished by pressure operating on the bottle longitudinally thereot, and particularly to that class of such machines in which the pressure exerting mechanism, during the working" stroke relaxes in operating upon hottles exceeding a predetermined height.

it is one object oi this invention to provide a mechanism of this character which, in respect to reliability in operation, sim plicity and compactness of construction and strength and durability of its working parts shall constitute an Improvement on the lrnown mechanisms ot its class.

'l'he invention includes other novel teatures, salient among which are the improved means for feeding the closures to the sealing point; an improved type of sealing throat; such a construction and arrange' ment of the parts ot a sealing mechanism and closure t'eeding means as to secure their proper cooperation, under a condition of movement of one relatively to the other; and means whereby the bottle support may be adjusted to sustain the bottle at the nec essary average elevation. I

ln the accompanying drawings, l ure 1 is a side elevation of the machine; ig. 2 a front elevation of the upper portion thereof; Fig. 3 a side elevation oi the upper portion thereof, the hopper tor the closures being broken away; Fig. l a plan view, the hopper being removed and its feeding chute shown in section; Fig. 5 a vertical sectional view of the parts directly involved in the accomplishment of the sealing; Fig. 6 a transverse vertical sectional view of the lower part of the sealing-headcarrying plunger, with the body part ot' the sealing-head therein apfearing in elevation; Figs. 7 and 8 are a si e and lan views of said body part ol the sealing cad; Figs. 9

and 10 front and plan views of the stem controlling the r'eliet' of the pressure. and serving as an ejector; Fig. it a rear elevation of a detent coactive with said stern; Fig. 12 is a sectional view on line M, Fig. 1; Figs. 13 and 14 views of the detent d0 of the closure feeding means; and, Figs. 15 and 16 a plan and side elevation of two lorms of sealing throats.

the frame or pedestal a is journaled the drive shaft 5 carrying, freely revoluble thereon the pulley 0 and having a clutch d preferably of such type that when, upon operating a suitable controlling means, in cluding a treadle e, the clutch locks the shalt to the pullc so as to rotate therewith, such rotation wil proceed only through a single revolution of the shalt, being ter- Ininated by the automatic action ot a suit. able clutch-tri ping mechanism. daid shaft carries a cran disk on whose crank pin is arranged a bloc ll. which slides in a iorizontal slot 91 in a plunger j moving vertically and guided in such movement hy the plates is (bolted to the head Z of the ped estal) whose edges are received in vertical slots in opposite sides ot the plunger.

On the pedestal below and in vertical alinement jwith the plunger is lined an en ternally threaded post a onto which is screwed the internally threaded bottle sup port 0 having an external vertical rib p which is received by a tor-k 9 having a handle r and movable from the horiaontal position (Fig. l) pivotally to a vertical osition so as to" clear the rib and anew vertical adjustment ot the support oby screwing the same ineither direction upon the post.

The lower end or the planar y hasa chamber a from which eaten upwardly through the pluner a bore t. llhe front lower part u of tie plunger is removable. as shown.

The sealing head oi the machine includes, with the sealing appliance and other par w, the body part c, square in horizontal section. This is fitted into the chamber a (having removed the wall a) and has vertical movement therein limited on the one hand by the top ot said chamber and on the other hand by the shouldersw on said part 4) imping ing against shoulders at in the chamber (Fig. 6.) The lower end of the body part a has screwed onto it the throat holder y, the.

throat (or sealing appliance) being supported within it upon its inwardly proyectin'g tlange or lip a (Fig. 'l'he throat holder carries, pivoted to i, the usual flaring lid hit

mouthpiece 2 which is normally retained in its horizontal or working position by the latch 3.

It is preferred to employ a throat or sealing appliance of a type adapted to adjust itseli to cross-sectional variations in the shape of bottle heads entered thereinto. In Figs. 5 and 15 such a throat is shown consisting of segments "4 embraced by a spiral spring 5. In Fig. 16 the throat is simply a spiral spring 0 having its coils close together and each square in cross-section to give a smooth interior.

The body part '0 of the sealing head is penetrated by a vertical bore 7 which is reduced, at 8, at the lower end thereof, forming a shoulder 9. @n this shoulder rests normally the shoulder 10 of a stem 11 having trunnions 12 received by oppo as slots 12 in the part 12 (and thereby held against turning), and pressed downwardly a spiral spring 13 interposed between the top of the stemand a cap-plate 14: secured on the top of plunger 9'. This spring therefore normally maintains the stem and body part '0 at their lowestlimits of movement, the former in the body part and the latter in the lunger. In the inner face of the wall u is fitted a hardened plate 15 having a recess 16 in its inner face shaped at its upper end to form an inclined shoulder 16. In the adjacent face of the stem 11 at a somewhat lower point in the rest position ofthe stem is fitted another such plate 17 having a recess l8 shaped at its upper end to form an inclined shoulder 18. The front wall of the bodypart v has an aperture 19 occupied by a detent 20, of hardened material, which is pivotally seated in a recess 21 at the bottom of said aperture and which at its upper end is thicker than the said wall by just so much that when the recesses of the hardened pieces 16 and 17 are directly opposite each other said detent might-be rocked so as to clear either the one or the other of the shoulders 16' and 18. At the points 20' the detenthas surfaces which are inclined at the same angle as said shoulders. In the idle position of the parts (Fig. 5) the detent engages shoulder 16 and so locks body part '0 against elevation, being held in that position by the hardened plate 17 of the stem; when the stem rises until the-recess of its plate registers with the detent, upward pressure on body part a will cause the detent to wipe ofl of the shoulder 16 and enter the recess of plate 17, and on the return of the parts the shoulder 18 will wipe against the detent and rock it back into the recess of plate 15.

A is the bottle, and B a closure of the socalled crown type. Describing now the operation of the mechanism so far described: When the plunger j, ailordinga thrust-assuming member for the container-thrust-assuming member constituted by the sealing-head, is depressed,

the spring-pressed' stem 11 first impinges upon and thus presses the closure down upon the bottle mouth, and then the throat of the sealing-head, now positively locked to the plunger by detent 20, comes to bear upon the flange of the closure and turns each of .its component parts downwardly, thus contracting the closure and forcing its indentations into locking engagement with the lip C of the bottle, the'throat receiving the contracted closure. During this part of the movement of the interlocked plunger and sealing-head, the stem, yielding to the resistance ofi'ered by the bottle, stands substantially stationary. If the bottle exceeds a certain height the sealing-head will be depressed, relatively to the stem, sufiiciently to bring the detent opposite recess 18. The detent is normally impelled, due to opposing pressures exerted thereon by the plunger and sealing-head (once the latter bears upon the container) taken with the inclining of'the coasting surfaces 16' and 20, to move into position to release the sealing-head, being opposed as to such movement by its controlling member (stem 11) until the recess 18 is opposite the detent. When this latter relation of the parts is accomplished, therefore, the detent is wiped by the plunger into unlocking or releasing position, so that the plunger continues any further. downward movement alone. On the plunger rising, the pressure of spring 13 on the stem, taken with the inclining ofthe co-acting'surfaces 18 and 20', efiects the shifting of the detent into the initial or locking position as soon as the recess 16 again comes opposite the de tent, the stem clearing the sealed bottle from the throat. If the bottle is of less height than that indicated,the recess 18 will stand below the lowest limit of movement of the detent. The sealing will therefore i'nthis case be effected without release of the" sealing-head from the plunger.

Involved in the use of this apparatus is the advantage that, aside from the pressure of spring 13 (which is suflic'ientsimply to produce a hermetic contact between the soft lining of the closure and the bottle mouth and hold the closure properly seated during sealing), the compression strain to which the to the resistance of the closure to change in its sha e in order to accomplish sealing, being urther eliminated after sealing has been accomplished. Thus, so'far as strain on the bottle is concerned, in place of all bottles being subjected to a pressure which is calculated to overcome the maximum resistance of closures to bending, the strain is in each case only what is needed to accomplish such bending. The extent to which the sealing head yields after the scaling is accomplished may vary according to the ice bottle is subjected is precisely proportioned aerator without the closured bottle head. passing lll clear through the throat (necessitating some expedient thereupon to'clear it from the throat) and permitting bottles to be operated upon having necks too thick below the mouth to enter the throat a distance appreciable for compensation.

The machine is provided with a hopper 22 carried by the plunger j (and therefore moving therewith) and through whose discharge outlet 23 the closures are fed to the chute 24, being made to enter said outletin properly facing disposition by means, not shown, actuated by the oscillating spur Wheel 25. The chute discharges the closures through an aperture 526 in the side of the mouth piece 2 (Fig. 5), and in view of the described vertical movement of the sealing head in the plunger and the fact that it is preferable to have the discharge end of the chute at the moment when a closure leaves the same as close to the ultimate resting posi-' tion of the closure in the sealing head as possible, requiring a cavity 2'? to be formed in the side of arts of the sealing head for the reception 0 the discharge end of the chute, the-chute is made to recede out of such cavity during the up and down movement of the sealing head. 'llherefore, at its upper end, the chute is pivoted on the brackets 28 and is swung back and forth on its pivot as follows: A fixed cam plate 29 is secured to one of the plates is and in the cam slot 30 thereof plays a roller 31 on one end of a lever 32 fulcrumed at 33 in the plunger and having pivotally attached to its other end a latch 34 having a horizontal slot 35 with recesses 36 and 37 at the ends thereof. The chute has a laterally projecting pin 38 received by the recess 36, the interlocking of the latch and chute being preserved by the weight of the latch. As the plunger rises and falls, carrying with it the hopper and chute, the chuteswings back and forth,being made to clear the cavity 27 at the moment when the sealing head is released and recedes into the plunger with the bottle. When the pin 38 is made to engage in recess 37 the chute will be looked back temporaril out of coacting relation to the sealing hea Pivoted to the lower end of the chute, at 39, is a detent 40 for the closures; at one side of its fulcrum 39 it enters the slot 41 of the chute so as to bear against the underside of a closure (thus holding the same against advance under the pressure of those behind it), said detent being held in that position by a spring-pressed pawl 42, at the other side of its fulcrum, bearing against the chute. When the chute swings in to its feeding po sition the detent is tripped so as to release the closure held thereby and allow it to be advanced into the sealing head bythe pressure of those behind it. This tripping is preferably accomplished through the medium of a dog 43 pivoted in'the detent and engageable with the mouthpiece, shifting slightly upwardly on its pivot when, after the inception of the impact, the chute continues some further inward movement.

Attached to the plate 29 is a rack a l which engages with the spur-wheel 25 so that when the hopper moves with the plunger the mechanism in the hopper operated by the rotation of the plunger will be kept in motion.
