\ BOTTLE OAPZPING AND SEALING MACHIHE.

Application filed-February 25, 1916, Serial No. 80,8

To all whom it may concern:

Be it known that I, ALBERT WESTLAKE, a citizen of the United States, and,,a resident of the city, county, and State of New ,York, have invented certain new and useful Im-- provements in Bottle Capping. and Sealing Machines, of which the following is a specification.

My invention relates to machinery which is used in the rapid sealing of a continuous succession of bottles or other containers. This involves the seizing, one at a time, of the necessary capping disks or other sealing materials from a constantly replenished supply, subjecting the same to suitable treatment-to adapt them for application as closure seals and thereafter applying them to the bottle or other receptacle in such a way as to secure the proper and desired sealing.

More particularly the present invention, which is an outgrowth of the machine shown and described in my Patent No. 1,137,820, dated May 4, 1915, has reference to that s stem of closure operations which is designed to furnish and meet the requirements of what is known as a single service container, by which term is generally understood a bottle or other container or receptacle which is intended to be used only once in the condition in which it is put npon the market. In other words, when once opene the container and seal or closure cannot be reassembled. Such portions of the package, for instance a glass bottle, as may be desired for further use are collected and returned to the manufacturer while the undesirable parts, for instance the paper cap, are thrown away or destroyed. Where both container and cap are of fibrous material it is preferable that no portion should be preservedafter once used. 1

It will be understood that my present invention is not limited to any particular class of merchandise or to any particular form or materialof container but is applicable to all such articles as milk, spring and pickles, as are more satisfactorily marketed in such a way that the contents are protected against tamperingb'y reason of the fact that the connection between the closure device and the container cannot be restored without detection when once severed.

I In the accompanying drawings 1 have Specification of Letters Patent.

selected a milk bottle as the container to-be sealed because the protection of milk in transit from the bottle to the consumer is of striking importance with a view to health, cleanliness and the prevention of adultera tion or dilution and spread of disease.

In my said patent of May 4, 1915, 1 have shown a bottle as presented to the capping unit by means of a rotar table. In the present drawings I have illilstrated an endless chain feed instead of the rotary table.

The object of my present invention is to provide a bottle capping and sealing machine of simpler and stronger construction and of greater capacity, efiiciency and power.-

This machine 15 preferably, entirely auto matic so that the attendant has only to the feeding stack supplied with sealing the filled and capped bottles and substitutefresh and full bottles. Where occasion requires however, the mechanism can be. operated by hand power or foot power.

a detail to bring out more clearly Same letters indicate similar, parts in the diiierent drawings.

A, A, represent machine upon which mounted.

B, is a motor from which power is derived and transmitted to the various parts of the machine.

G, is a stack or feed cylinder in which are piled the sealing disks for capping the bottles as hereinafter explained. I

D, is aheating and sterilizing oven in which the disks are detained for a fixed length of time during their, passage from the feed cylinder to the bottle.

E, is the plunger head or capping tool by the action'ot which the disk is molded around the mouth. of the bottle.

the frame work of the the moving parts are F, is a table upon which the milk bottles are placed. and along which they are fed to and from the capping plunger.

is a rotating capping and carrying frame which cooperates inturn with the feed cylinder, the heating oven and the plunger head in thesuccessive steps. of the sealing and capping operation.

H, H,'indicate a series of bottles in position, traveling along the table F, the center bottle being directly under the capping tool.

I, I, I, I, represent carrier .disk rings mounted upon the frame G tioned that the rotation of the frame G brings one disk ring directly under the plunger, another directly-under the oven and a third under the feed slide at the same instant.

'J, (Fig. 4) is a feed slide by which the disks are slipped one at a time from the bottom of the feed cylinder and deposited upon the proper carrier disk ring.

K, is a counterbalance weight by means of Which the operating mechanism is enabled to accommodate itself to variations in pressure during the continuous capping and sealing operations.

These are the more prominent features of my improved machine and the power for operating all of these parts is derived from the motor B, through various mechanical devices of which convenient and practical types are shown in the drawings, but which may be modified or varied as desired, and as will be readily understood by persons skilled in the art. 1

All the operations of my improved ma- .chine are timed with reference to each other so that the complete cycle of operations beginning with the picking out of a sealing disk from the stack C, and ending with the delivery of a capped and sealed bottle will be performed regularly for ach fixed period during the running of the machine, This period. for the machine shown in the drawings I preferably fix at about ten seconds, so that a fresh bottle fully and effectively capped is delivered by the table F every ten seconds.

The motor B is mounted upon a shaft a,

which we will call the motor shaft and which is supported by the brackets b, 11,

secured to the base of the frame A.

This motor shaft carries a pinion c which meshes with a toothed gear d. (Fig. 5) on a worm shaft a, journaled in the brackets 6", b fastened upon the stem of the framework. This worm shaft carries the worm 'e, which engages the worm wheel L, mountted. on the cam shaft 0, journaled in the frame work.. This cam shaft carries the cam M, which acts upon the roller f and by the displacement of this cam all the operations of the capping and sealing mechanism are brought about. 7

and so posirotate intermittently by means lower end of the compound lever N and is held away from the cam by the weight of upper end of said lever, subject to the equalizing efiect produced by the counterbalance weight K.

The to and fro movement of the lower'arm of the lever N is utilized to reciprocate the plunger head E and thereby operate all the other driven devices as follows:

The lever is pivoted as at g to the bracket 5 and the upper end is connected by the link it, pivoted to it at g, to the elbow lever 0 at g".- This elbow leverO is pivoted at g to thegbrackct b and the other end at g to one branch of the counterbalance lever P upon the shaft a the outer end of which carries the counterbalance weight K, while the inner end at g? is pivoted to the lower end of the plunger head operating rod Q. This'rod extends vertically through the casing E, upon which the plunger head is 'the various devices and mechanisms operated by the mounted and is adjustably connected therewith by the screw support 2'. down thrust of this rod Q thus reciprocates the casing E and the plunger or capping tool .E the necessary distance to effect the proper capping and releasing of the bottle which is capped and sealed thereby.

The rotating carrier frame G is caused to of a rack j,

The up and secured to the plunger casing move up and down therewith. This rack meshes with a segmental gear d, mounted on a rock shaft a journaled in brackets secured to the stem of the frame A and, in the form shown in the drawings, adapted to receive a quarter turn to and fro for each reciprocation of the casing E and having a locking pin is.

This rock shaft a carries a pawl l (Fig.-

6.) which engages'one oflthe teeth of the.

four toothed ratchet wheel m, loosely mounted on the rock shaft a. Secured to this ratchet wheel is afgear wheel d", Which meshes with a gear 03 on the shaft a journaled in brackets secured to the frame A. The shaft 1 carries a beveled gear n, which engages a beveled gear 11. on the rotating carrier frameG. Itwill thus be seen that each reciprocation of the. rock shaft a com.- municates a quarter turn to the carrier frame G, by means of the pawl Z, ratchet m, toothed gears d", d and beveled gears n and n; and that this intermittent quarter turn occurs for each complete reciprocation of the plunger head E.

The rotary carrier G is shown in the drawing) with ceiving and supporting rings I, I, I, I.

These four rings I, I, I, I, are arranged around the rotary carrier G at equal dis tances from. each other and extend outwardly a suflicient distance to bring each provided (as four disks re- E so as to' rying wheels m, each of the elevator plates teeth t (Fig. 3

each reciprocation, of the slide;

mounted respectively on "2, 3, and 6) secured to disk ring in succession under the'feed slide J (Fig. 1) and subsequently under the oven D and plunger head E,-as the carrier G revolves. These disk rings have an opening through them sufliciently large to permit the passage of the elevator plates 0, o', (Fig. 1) the stems p, p','but small enough to permit a sealing disk to rest upon the disk ring during its travel? The upper surface of these rings is provided with grooves which co-act with the sealing fingers in securing a regular and perfect capping of the bottle in theusual man'- ner.--

The function of the elevator plate 0 is to receive a capping disk delivered to it by the feed slide J immediately 'above the disk ring I and deposit the same in its descent upon said ring. The function of the elevator plate 0 is to lift the sealing disk from that disk ring which is immediately under the oven D and carry it into the oven where it is heated to the proper temperature; after which said plate brings said heated disk downand deposits it on said disk ring by which it is then conveyed to the plunger head.

The reciprocation of these plates 0, 0, is caused by a rock shaft a naled on the frame work A and driven by an arm 9, mounted on said shaft and carrying at its outer end a roller 1' (Fig. 5), which is engaged by a suitable lug on the bottom of the rack 7, which causes the shaft a to rock against the tension of a spring 8, kFigs-Q. and 6) fastened to the frameA.

, t each end of the rock shaft (1 is an armg" I rovidedat its upper end with teetli t. hese teeth mesh respectively with pinions 0' on shafts a, journal'ed in brack ets attached to the frame Work A and carof which carries a steel band 8', attached to the stem p or p 0, 0 respectively; These stems p, p, are supported by and slide vertically in the brackets b b (Figs. the frame Work A.

The feed slide J is made to travel from the bottom of'the stack C to the adjacent disk rin I, as follows: v

The eed slide (Fig. 4) travels in the guide way or track u and is provided with on the under side, which mesh with .a pinion 0'', shown' in dotted lines in Fig. 4 on shaft a This shaft carries another pinionc which, as shown 1n-=Figs.'2 and 3 is driven by a rack 7''. secured to the plunger-head E.I The capping disks are pressed downward by the weight 4; and the function. of the slide is to receive and carry away the lowest disk at The feedingof the bottles H is accom- 7 plished by atravelingapron 'R, which travels over and'around the table F. This apron R (Fig. 6) our- 7 apron is provided with a series of angular holders 1/), 'w, the function of which is to steady the bottles as they. stand upon and are fed along by the traveling apron.

the point where the bottles come succes-. sively under the capping tool E, the table is-provided with an. open'spring holding device 8', which steadles and centers the bottle, but which is opened by the forward pressure of the bottle to allow it to pass on after it has been capped. The proper tension and traveling of the is secured by the sprockets -S, S, S, and S, of which the sprockets S are idlers and the sprocket S sprocket. This sprocket is mounted on the shaft a", mounted on the bracket I), dependin from the table F and carryin a bevele gear 71/ (Fig.- 3) which mes es with and is turned by beveled gear n (Fig.

4) on one end of the jointed crank rod T, on the other end of which is a beveled gear a. This beveled gear and crank rod derive their motion from the beveled gearn' on the rotary carrier G, as before stated. It Will be understood that in this way an intermittent feed is communicated to the apron R, each step of which corresponds to a quarter turn of the carrier, so timed as to bring a fresh bottle in position to be capped when the plunger E is ready todescend and cap it. i

U, is a dating device mounted near the disk stack C and constructed so that thedating stamp operated thereby descends and imprints the date on each disk as it is brought under said stamp by the feed slide J on its Way from the stack C to the disk ring I.

V, is a rheostat by which the power of the current which drives the motor B is regulated as desired.

As .before stated the various details of devices andmechanisms to bring about the desired steps of operationare only given as types of a practical character and may be largely varied without departing from the spirit of my invention. v

The complete operation of my improved machine, as.will be readily understood, is briefly as follows The stack C being supplied with sealing disks and a full bottle being placed on the table F, as shown in Fig. 1 (H) to the extreme right of the plunger head E, the machine is started by turning the lever of the rheostat V to transmit the desired current to the motor B.

The revolution of the motor shaft is com-- municated through the pinion 0, to the gear d. worm shaft a, worm-e. worm. wheel Lv and cam shaft a to the cam M. The revolution of this cam displaces the roller f,

thus reciprocating the plunger head orcappingtool E and plunger "head casing la',

. that when by means of the rack through which by means of the compound lever N, elbow lever O, counterbalance lever P and operating rod Q. The plunger'head E descends and caps the bottle immediately under it, if, as shown in Fig. 1, a bottle Is there together with a sealing disk ready for application. It will be readily understood the machine is first started the first three descents of the plunger head will take place, before the first bottle H has reached it, but that when the machine'is re-started all the descents of the plunger ma be utilized in capping.

s the slide J is pushed from under the stack 0 j, pinion 0 shaft a teeth t. The feed slide carpinion c and p With it a sealing disk from the botrying tom of the stack travels along the guide Way u, under the dating stamp U and over the disk ring I and'elevator plate 0, said feed slide opening itsjaws and depositing the sealing disk upon said elevator plate. As the plunger descends the the feed slide and synchronously the elevator plate 0' deposits upon the disk ring I,

it travels, a heateddisk received from the oven in $11116 oven when the plate began its descent.

reviousl ex lained are derived from the p y p ger head casing r, arm rock pinion c shaft and stems p, p. v
