BOTTLE-SEALING MACHINE.

To all whom 'it may concern:

Be it known that I, ALFRED L. WnIssEN- THANNER, a citizen of the Republic of France,

and a resident of New York city, State of New York; have invented a certain new and useful Improvement in Bottle-Sealing Ma-. chines, of which the following is a specification.

My invention relates to a machine for capping bottles and similar receptacles having an annular shoulder or bead around the head, the object being to construct a machine which shall comprise as an essential feature a chuck or die into which the bottle is forced in such manner as to reshape the cap to conform to the contour of the rim of the bottle, and in which provision is made for all inaccuracies or irregularities in the form and size of caps and bottlesliable to be met with in practice. This chuck in the form shown in the drawing is held rigidly against vertical movement, although it may be vertically movable, and is split longitudinal] to form a series of spring jaws which will a1 ow of a slight'radial yielding movement when a bottle is forced into it, thus securing a uniform and evenly distrib-' uted pressure upon the corner of the cap.

A further feature of the invention com-' prises a crimping or bending tool which operates to circumferentially bend the flange of the cap into locking engagement with the shoulder of the bottle, said tool being a ranged relatively to the chuck and its oper tion being so timed as to effect the desire crimping or bending after the cap has been reshaped and while the bottle is held fast between the table and the chuck.

Another feature ofthe invention comprises means for concavin the center of the cap'..

The invention wi I be understood by reference to the accompanying drawings in which Figure 1 is a side elevation of a bottle sealing machine embodying my invention in its preferred form; Fig. 2 is a front elevation with certain of the parts in section; Fig. 3 is a top plan view; Fig. 4 is a detail view of the head of the machine with the frame in section; Fig. 5 is an inverted plan-view of the head; Fig. 6 is a vertical section. of the head showing the means for closing the crimping tool about the neck of the bottle; Fig. 7 is a top plan view of the head of the machine; Fig. 8 is a sectional view on the plane of the line 88 of Fig. 6 lookin in the direction of the arrow; Fig. 9 is a detai view showing the bottle neck and chuck in position before sealing; Fig. 10

is a similar view showing the parts in osition after sealing Fig. 11 is a view part y in vertical section and partly in elevation illustrating the head of the machine of Fig. 1 with an addition, said addition corn rising means for depressing the center of t e cap after the sealing operation. tail in vertical section to illustrate the operation of the depressing device of Fig. 11.

Referring to the drawings the numeral 1 form of a casting whichis provided at its lower art with a bearing for a shaft 2 which shaft 1s also supported in a bearing in a standard 3. Pivotally su ported on a shaft the rear end of which, when depressed, is adapted to strike against the under side of an arm 6 secured to a rock shaft 7. On this rock shaft is an arm 8 (Figs. 1 and 3) the upper end of which is U-shaped and engages a collar 9 on a clutch 9' slidably keyed on shaft 2. This clutch, when the treadle is deressed, is, moved so as to bring pulley 11 into 0 erative engagement with the shaft 2 Where y the latter is rotated from the power shaft by a belt passing around the pulley 11. Supported in bearings'in the frame 1 is a shaft 12 on which is pivotally mounted a le- 'ver 13 the forward end of which is forked supported in tubular extensions 15 of the ame 1-. Passing longitudinally through aid sleeve is a s indle 16 which is surrounded by the forke ends of lever 13 but not in engagement therewith. The spindle 16 carries at its upper end a table 17 adapted to receive the bottle to be capped, and said table may be provided with a gage- 18 for the proper centering of the bottle. Clamped to and the lower wall of the sleeve 14, and surrounding the spindle 16, is a spring 20 which acts as a cushion when the bottle is forced upward a ainst the chuck.

Integra with the treadle 4 is an upwardly projecting arm 21, which, when the treadle ing om lever 13 therebly rocking said lever and elevating its forwar end and raising the sleeve 14, and through the s ring 20 also raising the spindle 16 so as to ring the bottle with relation to the chuck to about the osition shown in Fi 9. The rear end of ever 13 supports a rol er 23 which is adapted to be acted upon by a cam 24 fast on the designates the frame of the machine in the,

5 in the lower part of. the rame is a treadle 4,

(Fig. 2) and upon which rests a sleeve 14' spindle 16 is a split collar 19 between which 1s dapressed, acts against an arm 22 depend Fig. 12 is a decam 24 a short distance butnot far enough i to escape the ath of said am.

I shown in Fig. 9,. the cam 24 then acting upon "and the bending tool.

said spindle by a collar 31 which is forced be- .a chuck and will be so referred to. the bottle is forced upward these working bythe jaws 33 is substantially equal to the shaft 2. When the treadle4 is depressed, the roller 23 is moved away from the face of As stated a ove the depression of tre'adle 4 raises the bottle into about the position roller 23 will deliver a sudden blow so as to cause the lever 13 to further raise the sleeve 14 and to forcibly project the bottle against the chuck. As cam 24 wipes from off the roller 23, the weight of sleeve 14 is sufficient to rock lever 13 so as to bringv the roller 23 into contact with the face of cam 24, and to rock the treadle 4 through the arms, 22 and 21 to restore it to its normal position. A s ring 25 secured to the arm 6 will move the c utch in a reverse direction so as to release the pulley 11 and the machine will come to a position of rest.

Formed integral with the frame 1 is a head 26 bored longitudinally in alinement with the spindle 16 and adapted to support the chuck The head 26 is formed with four inwardly projecting lugs 27 which permit of the free passage between them of a spindle 28. To the under side of the lug; 27 are bolted brackets 29 ,which are formed integral with a steel ring 30 which surrounds the spindle 28 said ring being clamped about tween said ring and the inner walls of the lugs 27. The spindle 28 is screw-threaded for a portion of its length to receive a jam nut 32 which is forced up against the lower end of the. ring 30. The ring 30 is also screwthreadedand adapted to engage the threaded portion of the spindle 28 so that said spindle may be adjusted vertically although held rigidly against vertical movement when once a justed. The lower end of the s indle 28 is reamed out to form a sleeve 33. he spindle is of steel and said sleeve is split longitudinally to provide a plurality of radially yielding spring jaws 33 having at the inner sides of their lower ends suitable concaved working faces. The sleeve 33 constitutes in efi'ect When faces. receive the corner of the cap.

The inner diameter of the chuck formed diameter of the rim of the smallest bottle liable to be met with in practice within the range of probable variations of size and she e. The function of the chuck is that of t e female member of a die so that under the pressure applied to the bottle acting as a punch a uniform and evenly distributed pressure will be applied about the corner of the cap to reshape it and to cause it to conformexactly to the rim ofthe bottle.

The present machine is designed not onlv frame.

to reshape the cap of the bottle but to bend the flange of the cap into secure locking eni gagement with theshoulder on the neck of the bottle. The mechanism for accomplishthe latter object of the invention is as i I f dTlows:Having a loose bearing on a stationary shaft (see Fig. 1) is a lever 34 one arm of which carries a roller 35 held in con tact with the face of a cam 36, fast on the shaft 2, by a spring. 37 secured to the other arm of'said lever and to a fixed stud on the The other arm of lever 34 is secured to one end of a vertical rod 38 the upper end of said rod being pivotally hung to a stirrup 39 encircling and secured to a lever 40, said lever 40 being pivoted on a shaft 41 having hearings in the frame. The forward end of lever 40 is forked (Figs. 1 and 3), and in slots 41 formed in the projecting arms are supported lugs 42 integral with a sleeve 43. The spindle 28 projects into said sleeve in the vertical movements of the latter. The lower end of sleeve 43- is formed with a cam face 44 adapted to operate a sectional flange bending tool which is constituted of a series of jaws 45 each having an inwardly projecting shoulder 46 made with a more or less sharp crimping edge 47- These jaws 45 are struck on the arc of a circle and when assembled constitutea bending tool adapted to bend the flange of a sealing cap into locking engagement with a shoulder on the bottle head.- Each jaw is formed with a shoulder on its inner upper wall adapted to engage a collar 48 secured to the spindle 28, the latter beingcentrally disposed within the bending tool. To the outer side of each jaw 45 is secured, by means ofa screw bolt, the lower end of a spring. arm 49, said springs being bowed outwardly (Figs. 4 and6) and tightly clamped at their upper ends between the ring30 and collar 31 (Fig. 6). The normal positions of the jaws 45 is such as to leave a space between contiguous edges so as to permit their lower ends to be moved inwardly to form a practically closed circle about the neck of the bottle when pressure is applied to the sides of the spring arms 49. The crimping edge 47 may be smooth or knurled, and a greater or less number of jaws than that shown in the drawings may be arran ed. This closing in of the jaws of the bending tool is effected by cam 44 through levers 5O pivoted on studs 51 secured to the contiguous walls of brackets 29 (Figs. 4 and 8). The levers 50 carry at their upper endsrollers 52 and at their lower ends are formed with threaded eyes 53 to receive adjustable bolts 54 which bolts'project into close proximity to the bowed sides (if-spring arms 49. These parts are so adjusted that as the sleeve 43-is moved downward onthe spindle 28 the cam 44 will contact with rollers 52 thereby rocking levers 50 and forcing the bolts 54 against the spring arms 49 to close the jaws 45 of the bending tool about the neck of the bottle.

The operation of the machine will be readily understood from the foregoing descrip- ,tion. The cams 24 and 36 are so disposed on the shaft 2 relative to eachother that the former acts u on lever 13 to force the bottle tially the position shown in Fig. 9-. Such movement of the treadle also moves the roller 23 away from, but not out of the path of, cam 24 so that as said cam is rotated a sharp blow will be delivered against roller 23 to impart a further vertical movementto sleeve 14, thereby forcibly im inging the to of the bottle against the chuc the plane 0 impact extendin over the corner of the cap 55. I The internal diameter of the face of the chuck and its configuration are such, relatively to a standard shape and size of bottle and cap, as to effect a reshaping. of the cap into exact conformity with the rim of the bottle. The sealing disk 56' on .the under side of the cap is compressed over the rim and the metal of the crown of the ca formed into a slightly convexed form. e spring 20 inclosed within sleeve 14 takes the force of the impact of the bottle a ainst the chuck and prevents breakage. A though the chuck is held rigid against vertical movement the capability of radial expansion of the jaws 33 of the chuck, provides for all variations from a standard shape and size thereby securing uniformity of pressure circumferentially around the corner of the cap.

the cap, the-cam 36 acts. to raise the outer end of lever 34 thereby depressing lever 40 and bringing the cam face 44 down-against the rollers 52 and rocking levers 50 on their pivots. The inward movement of the bolts 54 against spring arms 49 effects a closing-in movement of the jaws 45 against the flange 57 of the ca the crimping edge 47 formed by the severa shoulders 46 being practically continuous around the bottle neck. The u ward movement of the bottle brings t e shoulder 58 in such position that the inward movement of the jaws 45 will cause the edge 47 to bend the flange of the cap into secure locking e agement with said shoulder as indicated in ig. 10. Owing to the manner of SIxJSPOItlIIg the jaws 45 they are capable not 0 y of a radial movement but also a vertical displacement downward due to the flexing of the spring arms 49, so that notwithstanding irregularities in the size and shape of the bottle shoulders and caps the edge 47 will always be brought into a position to eflect the bending of the cap flange 57 under the shoulder. Thus if the height of the shoulder should be greater than the normal or standard the edge 47 will strike the shoulder at After cam 24 has thus acted to effect the compression and reshaping of.

"some point between its middle and lower circumferential lines and the jaws 45 will accommodate themselves to such variation by sliding over the curved under side of the shoulder so as to bend the flange into pro er locking engagement with the shoulder. he length of levers 50 is so roportioned that the bolts-54 strike a little a ove the center of the bowed portions of spring arms 49 to permit "of this slight downward movement of the jaws 45. and to effect the'desired inward radial movement of said jaws.

It will be understood that the extent of the movements of the jaws 45 is very small, bein merely sufiicie'nt to effect the desired ben ing of the cap'flange into intimate looking engagement with the shoulder.

When the high point of cam 36 wipes from underroller 35, spring 37 acts to raise cam 44 through rod 38 thereby releasing the spring arms 49 and permitting the jaws 45 to resume their normal positions. During the crim ing operation the cam 24 maintains the bott e pressed against the chuck and as soon as thecrimping is completed said cam wipes from OH the roller 23 thus permitting the sleeve 14 to fall, said sleeve in its descent rocking the lever 13 until the arm 22 im pinges against t-hearm 21 of the treadle 4, the latter-being held in its depressed position by a suitable stop. The bottle then being free may be removed from the machine.

The yielding characteristic of the jaws of both. the chuck and the bending tool permits them to give sufficiently and to prevent the breakin or crushing of the bottle, and to accommo ate variable sizes and shapes of hottles and caps.

In Figs. 11 and 12 I have shown a modification or addition to the machine. In this modification the spindle 28 is bored lon itudinally throughout its length but fixed y supported against vertical movement as described heretofore. The sleeve 43 which carries cam 44 is open at the top, and throu h said opening and passing 'ongitudinal y through spindle 28 to near the face of the chuck 33 1s a plunger 59, said plunger being supported by a spring 60-surrounding its head and bearing against the top of sleeve 43 and a nut 61 carried by theplun er. Pivotally supported on the shaft 41 1s a 'or- Wardly' projecting 'arm 62 the'outer end of which is rovided wit-h a hammer head 63 suspende above the plunger 59 and adapted to deliver a blow thereto when lever 40 is depressed by cam 36. Near one end of lever 40 is secured ashoe 64 adapted to engage the under side of a lug 65 projecting from a late 66 whichdplate is supported u on screw olts 67 tappe into arm 62. the lever 40 is in its raised osition thus suporting arm 62 in a position to deliver its low. When lever 40 is depressed the shoe 64 is-moved from under lug 65 and through the spring connection 68, arm 62 is moved downward and a blow delivered by hammer 63 to plunger 59, the parts being so proportioned that the plunger will strike the crown of the cap at or lmmedi'ately after the time of 0 eration of the bending tool by cam 44.. The lower end of plunger 59 is conveXed as shown and the diameter of the striking face is such'as to concave the crown of the cap as shown in Fig. 12, thus effecting a thoroughly eflicient seal. An adjustable stop 69 secured to a lug on arm 62 limits the downward movement of arm 62 so that shoe 64 on its return movement will be held in a position to sustain arm 62. The plate 66 may be slotted as shown in the drawing so as to adjust the position of lug 65 relative to said shoe.
