9 Claims. (Ci. 226-86) R The invention relates particularly to the application of closures to milk bottles. v

Milk bottles are generally closed by means of a cardboard disk which is inserted in the mouth of the bottle, after the same has been filled, the 10 disk being automatically inserted by the capping head of the machine. Various designs of capping heads have been used, the design varying according to the particular style of disk or plug cap being employed. I

While the plug cap effectively closes the mouth of the bottle, it possesses the disadvantage of not covering the top edge of the bottle and keeping itin a sanitary condition.

Various types of caps have been developed for 2 use as a closure for the bottle and at the same bottle. However, these paper caps, in all instances that I am aware of, are pre-formed, or finally shaped, at. the time of manufacture. This results in a comparatively thick bottle cap which must be of suflicient height to extend upwardly from the shoulder, or cap seat, in the mouth of the bottle over the top of the bead, or pouring lip, of the bottle. Such caps occupy, in so the shipping tubes and capper head magazines, four or five times the space of the common plug cap. Also, because of the great thickness or total height of the cap, the caps are somewhat diflicult to feed into the capping head, and are also more liable to become disarranged in the magazine. Due to the comparatively large variation in sizes Gil I and shapes of bottles, the pre-formed caps often do not fit the mouth or bead of the bottle, with the result that they are easilydisplaced from the 40 bottle during ordinary handling of the bottle.

A further object of the invention is a capper head which, during the formation and application 6 50 of the cap to the bottle, forms the peripheral margin of the cap with a plurality of radially extending ribs, or corrugations, which efiectively stiffen the peripheral margin of the cap and tends to,

maintain the cap in tight contact with the bottle 5 mouth.

time provide a covering for the upper edge of the A further object of' the invention is a capper head provided with means for radially expanding that portion of the cap contiguous to the bore in the mouth of the bottle'against .the same, whereby the cap is accurately shaped to each in- 5 dividual bottle, regardless of variations in size and shape of the bottles. v

A further object of the invention is a capper head employing means for transferring successively the comparatively thin flat disks from'the 10 magazine to the throat of the capper in such manner that the disks do not become disarranged,

. and are transferred to a position concentric with the mouth of the bottle.

A further object of the invention is a capper 1 head of such novel construction that while possessing the above features may be readily completely disassembled, whereby all the operating parts may be easily cleaned.

A further object of'the invention is the novel method of applying closures to milk bottles and the like, as disclosed herein.

The invention, insofar as it concerns the machine, consists in the novel features and in the combinations and constructions hereinafter set forth and claimed.

In describing this invention, reference is had to the accompanying drawings in which like characters designate corresponding'parts in all the views.

ing the parts in operative position when the 010 sure is applied to the bottle. I Figure 4 is a view, similar to Figure 3,.showing a dlsk overlying the top of the bottle and the operative parts in. position previous to the capping operation. 40

Figure 5 is a top plan view of the base of the capper head with-the body portion removed.

Figure 6 is a view taken on line 6-6, Figure 5. Figure '7 is a. perspectiveview of the cap after it is formed from the disk. The method herein. described of applying e10.- sures to milk bottles and the like, consists in placing a flat paper disk on'the mouth of the bottle with the peripheral margin of the disk overlying the top edgeof the bottle, pressing the peripheral margin of the disk against the top edge of the bottle, pressing the central portion of the disk into the bore of the mouth of the bottle and simultaneously during such pressing action forming a plurality of radially extending corrugations in the peripheral flange of the disk.

The-particular machine here shown for carrying out this method consists generally of a body provided with a passage to receive the upper end of the bottle, a magazine arranged to receive a plurality of disks in stack formation, a reciprocating slide member operable to successively transfer the disks from the magazine to said passage with theperipheral margin of the disk overlying the top edge of the bottle, an annular member arranged concentrically with said passage and being slidable in the body toward and from the bottle, a plunger slidably mounted in the body and arranged within said annular mem her and being operable to press the central portion of the disk into the mouth of the bottle, and means for moving said annular member against the disk to press the same against the top edge of the bottle, and means for moving the plunger toward and from the bottle.

The capper head, herein described, further includes means operable for effecting radial expansion of the lower end of the plunger to press that portion of the cap, contiguous to the vertical bore in the mouth of the bottle, against said bore.

[8 designates generally the body which, as here shown, consists of cylindrical portions H, l2, arranged in vertical spaced apart relationship upon the base l3 to which the body is detachably secured by screws I4. The rear cylindrical portion l2 constitutes a magazine for receiving and holding a plurality of flat paper disks I5 in stack formation. The upper end of the magazine is provided with a straight cylindrical bore to slidably receive the tube l6 which is usually of cardboard or paper board in which the disks i5 are shipped to the dairy.

The forward cylindrical portion II is forme with a straight cylindrical bore in which is mounted the mechanism for forming a disk l5 into a cap and simultaneously applying the same to the bottle. The forward portion of the base, beneath the cylindrical portion Ii, is provided with a circular bottle receiving passage, the lower portion l8 of the passage being conical to act, more or less, as a centering device for the bottle as the capper head descends upon the same, as will be well understood by those familiar with devices of this kind.

The upper portion of the passage, Figures 3, 4, is here shown as counterbored, as at I9, to receive an annular member 20 having a radially inwardly extending flange 2|. The inner surface of the -flange 2| is formed preferably on the same angle .and arranged in axial alinement with the conical bore l8, and is of such diameter that when resting on the bead of the bottle B, Figures 3, 4, the upper surface of the flange 2| willbe located in substantially the same plane as the top of the 80 bottle.

The bottom of the body intermediate the cylindrical portions ll, I2, and the contiguous portion of the base are relieved to provide a slot or horizontal throat 22 through which the disks I5 are successively transferred from the magazine to the annular member 20 with the peripheral margin of the disk overlying the top of the bottle.

The base I3 has a rearwardly extending portion 23 on which block 24 is slidably mounted.

The block 24 being U shaped in cross section with the legs of the U extending upwardly straddling the rear portion 23 of the base. attached to the upper ends of the legs of the block 24 by screws 26. The-forward end of the plate 25 extends into the bottom of the magazine, and as A plate 25 is the block 24 and plate 25 are reciprocated, the lowermost cap l5 of the stack in the magazine is transferred through the throat 22 into the annular member 28'. The block 24 is provided with laterally extending trunnions 28 to which the 5 rear ends of the links 29 are pivotally connected, Figures 1 and 2. The forward ends of the links 29 are pivotally connected to the lower arm of angle lever 38, as at 3|. This pivotal connection includes a lost motion arrangement in that the 10 forward ends of the links 28 are provided with an elongated slot 32', and the contiguous arm of the lever 30 is provided with a spring 33 which normally maintains the links 29, block 24, plate 25, in the rearmost position. The levers 38 are 15 pivoted at their angle to a rod 34 extending through the body intermediate the cylindrical portions ll, l2, the levers 38 being also provided with an elongated slot at this point. The upper arm of the lever 38 is pivotally connected to a 20 red 38 extending through slots 31 arranged in opposite sides of the cylindrical portion II and also through the shaft 38. a

The pin 38, in addition to acting as a pivotal connection between the levers 38 and the shaft 25 38, also prevents relative rotary movement between the capping head and the shaft 38. It will be well understood by those familiar with these devices that the shaft 38 is suitably secured to a reciprocating power driven member of the cap- 30 ping machine, not shown, whereby upon vertical movement of the shaft, vertical movement is imparted to the capper head as a whole, and when the head coacts with the top of the bottle B, further downward movement of the shaft 38 35 effects application of the cap to the bottle. Thereafter, the upward movement of the shaft 38 first effects forward movement of the slide 25 through the links 29, levers 38, in the well known manner to transfer another cap into position to 40 be applied to the bottle.

The transfer mechanism here shown is, generally speaking, similar to that heretofore extensively employed. The forward end of the slide member 25 however, is of particular construc- 45 tion to effect proper transfer of the thin paper disks l5, and the slide 25 also carries a member cooperable during each reciprocation of the slide to arrange the caps in the bottom of the magazine in a predetermined relationship, as will be here- 50 inafter described.

The forward end of the slide 25 is bifurcated, or formed with a central slot 48, and the ends 4| are arcuate and of reduced thickness forming an arcuate shoulder 42, the curvature of which is 55 complemental to the diameter of the disks ll. The lower portion 44 of the bore in the disk magazine extends at substantially an angle of 45 degrees to the axis of the magazine, the bore sloping upwardly and rearwardly from the pas- 0 sage 22, Figures 3, 4, and the rear side of the magazine i2 is provided with an opening 45 which may extend from the base l3 upwardly an appreciable distance, as indicated in Figures 3, 4, and the lower end of the tube i8 may be pro- 65 vided with a slot, not shown, arranged in alinement with the opening 45, whereby the disks I! may be inspected by the operator during opera? tion of the capper head, whereby the operator is informed when it is necessary to insert a new 70 tube of disks.

A block 48 is secured to the upper face of the slide 25 by screws 41. The forward surface of the block 48,-toward the magazine, extends at an angle equal to the angle of the bore 44, and 75 the block 46 is so positioned relatively to the plate that the forward side of the block coacts with the rear sides of the bottommost disks in the magazine, whereby during each reciprocation of the plate 25, the bottom disks in the magazine are moved, or shifted, against the forward portion of the angular bore 44, whereby the caps are alined therewith. With this construction, the lowermost disks in the stack are arranged axially of the capping head in overlapping relationship, whereby the ends of the slide 25 may separate the lowermost disk in the stack more easily.. When the plate 25 is in the rearmost position, Figures 1, 2, the shoulders 42 on the forward ends of the'plate 25 are flush, or in alinement with the rear wall of the angular bore 44, whereby the rear edge portion of the lowermost disk in the stack is permitted to rest upon the ends 4| of the plate. The shoulders 42 are slightly less in height than the thickness of the disk |5, whereby upon forward movement of the late 25, the lowermost disk is carried and p I ed through the throat 22 into the annular Zing 20 where the disk overlies the top of the 'ottle resting upon the ledge or flange 2 I.

The vertical portion of the annular member 20 "is cut away on the side contiguous to the passage 22 in alinement with the sides 58 of the passage 22, or that portion thereof formed in the base l3, with the exception of a small portion 5| located in the medial line of the base, and which portion 5| is formed with a slot 52 inits upper side. The base i3 is likewise provided in its upper side adjacent the annular member 20 with a pair of spaced apart ribs 53 which are arranged upon each side of the slot 52. The purpose of the portion 5| is to prevent the disks l5 from becoming displaced out of the annularmember 20. I

The center of the rearwardly extending portion 23 of the base I8 is relieved, as at 54. A flat spring 55 extends diametrically under the cap magazine, and is secured at its rear end in the relief portion 54 of the base, as at 56. The forward end 58 of the spring 55 tends to move upwardly against the bottom of the intermediate portion of the body l8, and extends be tween the ribs 53 and through the slot 52 and portion 5| of annular member 20. The slot 40 is formed in the plate 25 to permit the ends 4| of the plate to straddle the spring 55 when the plate 25 is moved to forward position. see Figure 4. The purpose of the spring 55 is to pre- -vent the plate 25 from retracting the disk before the ends 4| of the plate are withdrawn from beneath the rear edge of the disk, and the disk permitted to drop on the ledge 2|.

In operation, as the disk I 5 is moved toward the annular member 28, the free end 58 of the spring 55 is depressed between the ribs 53 and into the Y slot 52 permitting the disk to'pass over the spring. Assoon as the rear edge of the disk clears the free end of the spring, the spring is permitted to rise slightly in contact with'the bottom of the body, because of the slot 48 and the foward end of the plate 25. As the plate 25 then moves rearwardly, the end 58 of the spring 55 contacts the rear edge of the disk and prevents it from being retracted from the annular member 28. As soon as the ends 4| of the plate 25 clear the disk, the disk is permitted to drop upon the flange 2| and is prevented from rearward movement by the projection 5|.

By the novel method and apparatus herein employed, the cap can be formed of thin paper,

disks which, on account of their thinness and atmospheric conditions, often have a tendency to curl up or become otherwise disarranged, presenting diiiiculties in effectively separating the lowermost cap of the stack and transferring it to the annular member 20. This difficulty is principally overcome by the arrangement of the angular bore 44, and the arranging block 46, together with the particular construction of the forward end of the slide plate 25. However, to more effectively effect separation from the lowermost disk, the body It, intermediate the magazine and the cylindrical portion ll, may be provided with an aperture extending upwardly from the base in which is slidably mounted a pin 68, the lower end of which is formed conical on an angle complementalto the angle of the bore 44. The aperture and pin is so arranged relatively to the bore that the conical end of the pin 6|! extends in alinement with the bore 44. As the lowermost cap is moved forwardly, by operation of the plate 25, the pin 88 is moved upwardly so that the forward edge of the disk passes under the lower end of the pin which, however, is still in contact with the'forward edge of the disk immediately above and prevents any tendency of the upper disk following along with the lower-.

shaft 66 contiguous to the head is of reduced A cup shaped member 61 is slidably diameter. mounted in the cylindrical portion H, and as here shown is constructed with a ring 58 inserted in the lower end thereof. and being of such external diameter as to slidably fit a ring 69 inserted in the bottom end of the body. The exposed end of the ring 68 is serrated or formed with a plurality of radially extending ribs 18, Figure 4. The cup shaped member 81 may be of one-piece construction. However, it is preferable that the annular member or ring 68 be formed of steel and hardened. The bottom of the cup shaped member 61 is provided with an aperture to slidably receive the shaft 38.

A ram o-r'plunger is carried by the lower end of the shaft 38 and has relative axial movement thereto. The plunger comprises an upper portion 12 provided with an aperture to slidably receive the head 65 of the shaft 38. and a lower thickened portion 13 provided with "a con cal bore complemental to the conical end of the head 65. The upper and lower portions 12,13, are connected by a comparatively thin cylindrical wall slid ng movement relative to the shaft for a distance equal 'tothe length of the reduced portion 66. The lower thickened end portion 13 and the side wall 14 are provided with a plurality of axially extending slots 18, Figures 3, 4. Or, in other words, the plunger 15- is somewhat used in machine tools and the like, and is preferably formed'of steel and hardened. Theinterrn'ediate wall 14 and the upper peripheral surof the construction of the ordinary spring collet disk 82 which is secured to the shaft 38 by the pin 36, previously referred to.

In operation, the shaft 38 and entire capping head descends until the base l8 rests upon the top head of the bottle B, at which time a disk has been transferred from the magazine to the annular member 20, as shown in Figure 4. -Further downward movement of the shaft 38 causes the cup shaped member 81, or the ring thereof, to press upon the peripheral margirbof the disk, with the disk interposed between the ring 68 and the top edge of the bottle. Upon further downward movement of the shaft 38, the springs 8| are compressed and the plunger or'ram moved downwardly relatively to the ring 68. This movement is accomplished by contact of the conical end of the head portion 65 of the shaft with the conical bore of the lower end portion l3 of the plunger. This movement of the plunger presses the central portion of the disk into the mouth of the bottle. That is, the disk is drawn into an inverted cup shaped closure with the upper end of the bottle acting as the drawing die, and the plunger as the punch. This movement continues until the central portion of the cap seats against the shoulder in the mouth of the bottle. The downward movement of the plunger is thus arrested, and further downward movement of the shaft 38 causes the lower end portion 13 of the plunger to expand radially outwardly. This movement is effected by the relative movement between the end portion or portions 13 and the conical end of the shaft 88. Preferably, the ribs on the periphery of the lower end portion 13 of the plunger are complemental to theradially extending ribs orserrations 10 formed on the lower end of the ring 88.

Withthe motions above referred to, the disk is drawn into a cap C, as shown in Figure '7, and inserted into the mouth of the bottle. The shaft 38 is then moved upwardly first permitting the end portion I3 to spring radially inwardly and then, as the head 65 contacts the disk I6 the plunger is moved upwardly out of the mouth of the bottle and into the ring member 68.

As the shaft 38 moves upwardly, the disk 18 contacts the bottom of the'cup shaped member 81 and moves the latter upwardly.

As the shaft 38 continues to move upwardly,

the disk 82 contacts a disk 84 which is detachably secured in the upper end of the tubular member Ii. As here shown, the disk 84 which, as shown in Figures 1, 3, and 4, is provided with an 'aperture to slidably receive the shaft 38, is provided with a plurality of radially extending studs 85, the outer ends of which are threaded to receive the nuts 88. The upper end of the tubular member i i is provided with lengthwise extending slots 81 to receive the studs 85. When the nuts 86 are tightened, the disk 84 is secured in the upper end of the tubular member II as shown.

During this upward movement, the angle levers 30 are operated about their pivots effecting sliding actuation to-the plate 25 to effect transfer of another disk from the magazine to the annular member 20, as previously described. A ring 88 is secured to the rear of the housing ii at 89,

and functions as a guide and support for the disk tube It.

It will be observed that the action of the cap forming and applying mechanism is such as to evenly draw the disk into a cap with the excess material, caused by the drawing operation, evenly distributed throughout the circumference of the cap, and. with the cap accurately formed to fit each individual bottle. The function of the serrations 18 on the lower end of the annular member 68 is to form a plurality of radially extending corrugations in the peripheral margin of the disk which accommodate the excess material as the central portion of the disk is drawn downwardly over the bead and into the mouth of the bottle. The function, of the axial extending serrations 80 on the lower periphery of the plunger or ram is to maintain the ribs formed in the peripheral margin of the disk or cap, so that these ridges or corrugations extend frmn the peripheral edge' of the cap down to the shoulder in the mouth of.

the bottle, and are uniformly and evenly spaced.

It will be understood that these corrugations maof the mouths of the bottles, the cap is formed to the mouth of the bottle and pressed radially outwardly against the bore in the mouth of the bottle, with the result that an effective seal is secured and the cap tightly held in place.

As will be well understood by those familiar with the practical operation of dairy machinery, it is highly desirable that such machines be so constructed that the machine may be readily and conveniently disassembled so that any milk,

or cream, that may have accumulated on the machine may be removed before it becomes sour, or rancid. Attention is particularly called to the construction herein described which may be completely disassembled with a minimum expenditure of time, and easily cleaned and reassembled. To completely disassemble the machine, it is only necessary to loosen the nuts 88, whereupon the body and base of the capping head may be readily dropped from the shaft 88 and the cap forming and applying elements which may be then conveniently rinsed OH with a hose, or otherwise cleaned, and the body again secured to the disk 84.
