HEAD .FOR BTTLE-CAPPING MACHINES..

Specification of Letters Patent. Patented Oct, v26, 1909.

Application filed January 29, 1909. Serial No. 475,006.

To all whom 'it may concern:

le it linown that l, liolns C. KRUMMEL, a citizen of the United States, residing at Clinton, in the county ol" lvliddlesex, State of Connecticut, have invented. certain new and useful Inlprovements in lleads for Bottle-Capping h'lachincs, hf which the following is a description, reference being had to the zweonipanying, drawing, and to the iigures of reference marked thereon.

The invention relates to machines for capping bottles, and more especially to that class of machines in which the nietal cap is placed on the inout-h of the bottle, and the flange of the'cap is turned umlerneath the shoulder at the mouth ofthe bottle, thereby securing the ea p to lsaid bottle.

An object oi the invention is to provide a head for a machine oi the above cl'iaracter, which head shall b e durable in construction and eiiicient in operation.

A further object of the invention is to provide a bottle-capping head with means for securing the cap to the bottle, which nieans includes devices for lil'niting the nnwelnents of the parts, so that undue or breaking pres sure will not be applied to the mouth of the bottle, during the closing of the cap.

A further object of the invention is to provide a'bottle-capping head which includes a cap-receiving chuck, movable longitudinally independently of the head.

A further object of the invention is to provide a bottle-capping head with a cap-receiving chuck and with an ejector, for fore-- ing the capped bottle out of the chuck.

A further obj ect of the invention is to provide a bottle-capping head having a' chuck which is movable longitudinally in the head, and a cap ejector, which head is so positioned relative tov the 4cap-holding' devices that the ejector and chuck serve to 4steady the cap and hold the sanie on the bottle until properly received by thehead.

These and other objects will in part be obvious, and will in part be hereinafter more fully described.

In the drawings, which show by Way of illustration one embodiment of the invention,-Figure 1- Iis a sectional view through my improved head; also showing` its relation to a cap-holding device; Fig. 2 is a sectional view on the line 22, yof Fig. 1; Fi 3 is a sectional view of certain partsof the head, showing the head expanded, that is, with the inner lsleeve -inoved to its extreme position out of the outer sleeve-g Fig. 4 is a side elevation of the head; Fig. 5 is a sectional detail, showing a modified form of the invention in that the ejector is positively operated. `Fig. is a View similar to F ig. 1, showing a lnodiicalforln lot' chuck support. Fig. Tis a detail of the housing for the springs. FigzjS is a view on the line 8 8 of Fig. 7; and Fig. 9 1s a detail View of the chuch-operating device.

The entire head 1, as herein shown, is carried by a spindle 2, which may be the spindle oi any suitable bottle cappino' machine, orot any other machine that will give the head. a( rapid rotary motion.

ln Fig. 1, the bottlecapping head is shown asV rotating above a cap-holding device 3, which cap-holding device may be a part otA any suitable automatic cap-feeding nieclnuiisln. It will be obvious, however, that from certain aspects of the invention, the bottle-capping head may be used With. out any cap-feeding device, the caps being placed by hand on the bottle, which is inserted intothecapping head.

My improved capping head comprises an outer sleeve 4, which is-threaded on to the spindle Said outer sleeve is recessed to receive an inner sleeve 5, which is connected to the outer sleeve by a spline (i, so that the inner sleeve may inovc into and out ot the outer sleeve, but Will rotate with the outer sleeve.

Arspring 7. is located in aout out or recessed portion 8 of the spindle 2, and at one end bears against the spindle, While at its other end said spring bears against the inner sleeve.l The spring 7 will normally hold the inner sleeve in the position shown in Fig. 3, that is, Withdrawn from the outer sleeve, until the shoulder 9 engages the cap plate 10 carried bythe outersleeve. `In this position the head may be said to be expanded.

The inner sleeve is provided With a central recess in ,Which is mounted a'chuck 11. The chuck is threaded on ,to a sleeve 12. The sleeve 12 extends throughs collar 18,y which is threaded intothe innerl sleeve 5. Thein- 'i vner sleeve is provided with a shoulder 14 and a ball bearing rests on the ,shoulder 14, and is engaged at its upper side by the collar 13. The collar 13 is also 'pmy-ided with a reduced portion 16, which extends tates la down into the ball bearing 15. The reduced portion 16 terminates a. short distance above the lower side of the ball bearing.

The chuck 11 slides freely in the inner sleeve 5, and remains stationary during the cappi operation, while the inner sleeve rout the saine. When the chuck is in itsinnermost position, as shown in Fig. 1, it engages the ball bearing, which takes the end thrust caused by the forcin of the bottle up into thecapping head. ,'Iie sleeve 12 which carries the chuck 11, is provided with an enlarged head 17, which engages the upper face of the collar 13, and limits the downward movement of the chuck relative to the inner sleeve. A spring 18 entlie sleeve 12 at one end, and a collar y 19 at the other end, and operates tol norinalll'y hold the chuck in the position shown in i 17 of the sleeve 12 against the upper face ofthe collar 13. r

kThe chuck 11 is provided with aL bottlecap-receivin recess 20, which is constructed 'so as to con orin to the shape of the cap being secured to the bottle. The chuck is also provided with a further recess to receive an ejector ypad 21, carried by a stem v22, extending up through a central opening in the chuck, and which isv provided with an enlargedhead 23 at its upper end, which engages av shoulder 24 formed in the central recess of the chuck, so as to limit the 'downwardA movement of the ejector pad. An ejector rod 25 extends centrally through said head, and throu h the supporting spindle 2. The collar 19 a ve referred to, is carried by said ejector'rod. -The ejector rod at its lower end has a reduced portion 26,'having a rounded end normally bearing against the upper enlarged end 2,3 of thestem 22. A

spring 27 surrounds the reduced portion 26 of the ejector rod, and bears at one end against the shoulder on the ejector rod, and at the other end against thehead 23 of the Y stem 22.

The vcollar 13, which bears against the er face of the ball bearing 15, may be adjusted, owing to its threaded connection with the inner sleeve; As a means for hold-` ing said collar in its adjusted posit-ion, I

-have provided the collar with a plurality of semicircular recesses 28. The inner sleeve has also a vsimilar semicircular recess 29. The collar 13 is turned until one of the rccesses is brought opposite the semicircular recess 29, after which a screw or pin 30 may be inserted, to hold the collar 13 against accidental movement in the sleeve.

The closing roller 31 is herein shown as a corrugated crimping roller, although it is obvious from certain aspects of the inven` tion, that said roller might be a smooth surface roller for spinnino` the material of the cap underneath the flange on the bottle.

g. 3, that is, with the enlarged head The crimping roller 31 is mounted to rotate freely on a stud 32, carried by a'lever 33, pivotally su ported by a rod 34, carried by the inner s eeve. The-'inner sleeve is recessed' in order to provide a space for the supporting lever 33.` lhe outer sleeve has also a recess, in which is located a bar or plug 35, having at its upper end an enlarfrcd head 36, and having its lower end rounded to engage a similar rounded socket in the laterally projecting arni 37 of the lever 33. A spring 38 engages the upper end of the bar or plug 35. -A screw is threaded into the upper part of the recess in the outer sleeve, and serves as an abutment for the sprinni 38.

The ejector-operating rod` 25 may be spring pressed or may be positively operated. In Fig. 5 of the drawing, I have shown a slightly modified form otpconstruction of ejector-operating means. In this figure, the ejector head 40 is 'threaded direct y onlto the end of the ejector rod 41. The ejector rod extendsl u through the supporting spindle for the cad, and at its up er end is rovided with a split nut and kni'ic le 42, which is pivoted to the lever 43.

In the operation of my device, the bottle is yinserted up through. the cap-supportin device, which carries a metal cap provide with a packing, generally consisting of disks formed of a yieldino' material such as cork,

which will not be affected by the contents of.

the bottle.- The capping head, which is rotated continuously with the exception of the ejector pad, the chuck andthe ejector rod which are stationary, is located directly above the cap-supporting device, and the arts are normally in the osition shown in ull lines in Fig. 3, and in dotted lines in Fig. 1. In thisvposition it ,will ibeobserved..

that the ejector pad is located directly` above the cap, so that as soon as the bottle engages the cap and raises the same from its seat in the sup Lort for the'cap, said cap will be engaged by the ejector pad;i and held on the mouth of the bottle, and yrop- .erly directed into the receiving recess i the chuck. The chuck is also forced oiittvard from the capping head, and lies `in a position directly above the support for the cap. After the cap has been seated in thereceiving recess of the chuck, a further upward movement of the bottle carries the chuck and theejector pad up into the inner sleeve, which, as the capping head is exi,- panded, rests on the cap plate 10 ofthe outer sleeve. The crimping roller 31isat this time, thrown back or to the right, as shown in Fig. 3, by re'ason of the fact that the innersleeve is moved down out of the outer sleeve, carrying with it the supportinglzlever 33, and the arm 37 of the lever 33l has engaged the cap .plate 10, which throws the crimping roller -to theposition stated.

sleeve against the action of the spring 7.

-ing wheel is also a yielding movement, for

vbring aboutthe movements above stated.

A further upward movement of the bottle. forces the inner sleeve up into the outerv As the inner sleeve moves upward, the'lever carrying the crimping roller 31 also moves upward, and the arm 37 contacts with the plug or bar 35, which rotates the lever 38 about the supporting pin 34, and brings the crimping roller 3L into contact with the iange of the cap extending beneath the shoulder or. the mouth of the bottle. vlnasmuch as the head is continuously rotating, the crimping roller will be carried around the mouth of the bottle, which, together' s with the chuck and ejector pad, is stationar thus graduallyl turning the flange of the cap underneath the shoulder on the bottle. When the inner sleeve contacts-with the outer sleeve at its .'uppei'iel'id, a further movement of the inner sleeve upward is pre-l vented, and, therefore, the inward movement of the crimping wheel, that is, the movement of the crimping wheel into contactwith the flange of the cap, is positively limited. This inner movement of the crimpthe reason that the` plug or bar 35 may yield to the action of' the spring 38. lf, therefore, there should be an unevenness in the formation of the mouth of the bottle, so as to cause a breaking of the bottle, due to the excessive strain ofthe crimping wheel on the bottle, said crimping wheel would yieldto allow the uneven portion of the bottle to be properly passed. lt will be seen, therefore, that l have provided a device wherein the cap may be properly crimped and secured to the bottle, regardless of any uneven parts in the mouth of the bottle, and that'the force with which the flange is l turned underneath the shoulder on ythe mouth of the bottle may be adjusted by adjusting the screw 39, thus avoiding` the breaking ot the bottle.

After the cap has been secured to the bottle, the bottle is withdrawn from the -apping head, and the inner-'sleeve will first move out of the outer sleeve, after-which the chuck will move out oi the inner sleeve, and after the chuck and inner sleeveI have reached the limit of their downward movement, the ejector pad-will operate to force. the capped bottle out of the recess in t-he chuck. The movement of the ejector' pad downward, relative to the cap-supporting device is snilicieiit.` to force anybroken portions ot bottle down through the cap-supporting device, so as toprevent any clogging ot the apparatus.

li the ejector pad is operated positively, as shown in Fig. 5, the cam for operating the same will,`of course, be so timedasto That ijs, to allow the head to be expanded be'- fore' the bottle forcel from 'the chuck.'y

In Fig. G the spindle is a rotating spindle carrying the outer sleeve 4 and inner sleeve 5, vwhich are of the same construction as that described in connection with Fig. -l, and the same reference numerals have been' applied to the partst-hercof, The

chuck l1 is threaded on to the endof'a rod 44, which extends upv through the rotating spindle 2. Said chuck is recessed to receive the ejector' 23, which is held normally forced out from the chuck'by means of afsnitable spring 45, located in a recess `formed in the end of the rod 44, as shown in dot-ted lines in Fig. 6.' The spring 7, which holds "the crimping head expanded rests at its upper end against a collar 46 which 1s secured to the spindle 2 by suitable pins 47. 'The rodl 44 is thr aded and provided with an adjust-v able threaded collar 48. :A semi-cylindrical member 4t), is provided with perforated projecting ends 50, which slide over the rod 44. Said member 49 fits the inner bore of the spindle 2. The collar 48' is cut away as at 51, so that said collar is formed with shoul-.

ders 52,which, when the .opening in said' collar is in alinement with theopenings in the enlarged ends 50, rest.A against the edges of the semicylindrical 'member 49. The collar 48 is adjustla'bly secured to the rod 44, and by the shouldered connection with the cylindrical member 4f), said member is. held from rotating with the spindle A spring 53 surrounds the rod 44.l and rests normally at its lower end against the lower enlargedhmul' 50 of the cylindrical.

member 4f). A spring 54 also surrounds the v rod 44 and is located between the upper tace of the collar 4S, and the upper enlarged end 5() of the semieylindrical member 4S). In the operation of my device, 'the collar 48 is so adjusted that when said collar rests uponl the spring 53, thcchuck 11 is positioned as shownin Fig. (3, that is, said chuck extends into the cap-fecding head, but is held at a suilicient distance above the ledge or shelf supporting the caps, topermit said caps to be freely fed underneath said chucks. lVhen a bottle is raised into contact With. the ca "i, it is at once carried' into the recess terme in the chuck mving the ejector 23 up into its recess compressing the spring 45; A further upward'movement of the bottle causes the collar 48 to compress the spring 54, and allows the chuck 11 to engageA a ball bearing support, to cause the inner sleeve to move up into the outer sleeve in pre.

cisely the same manner as hereinbefore dcscribed. W hen the bottle 1s lowered after having been capped, the spring 54willmove` the rod 44, and the chuck 11, downward with the bottle.. The collar @.48 ,contacting -with the spring 53, limits the downward movement of the rod 44 and the chuck, and

holds the chuck in What-may be called itsv normai position. An anti-friction; washer or ball bearing 55 v,apports the semicylindrical member 49, and allows the spindle to rotate freely about said member. l l

In order to remove any broken caps or broken pieces of caps from the capping head, I may provide my capping head with means for moving the chuck down into the capping head to a point below the ledge on which l ing the spring 53. reaches its `lower position,

receiving chuck the caps normally rest, and thus positively .fo ce out of the capping head all said broken arts.- As herein shown, the rod 44 is provided with a split collar 5G, carrying pins 57, to'which is pivotal-ly connected a lever 58, fulcrumed at 59 upon any suitable support. A rod 60 having a collar' 61 secured thereto, passes through an opening in an enlarged portion of the lever 58, and said rod may be given a downward movement at the proper time l to be fed underneath the chuck.

If my device is applied to a machine wherein the sameis stopped after each capping operation, the positive operation of the chuck should, of course, occur before the machine stops. By adjusting the rod 44 in the threaded collar 48, the normal position of the" chuck may be varied. Y
