(01. 153-1) This invention relates to an improved method of forming sheet metal rims and bands for use on butter tubs and othercontainers and teen improved container embodying the useof an improved form of ban'd.1 1 1 1 It has: heretofore been the practicetoform metallic rims ;.for butter tubs and the like by passing a sheet metal bandjthrough a number of pairs ofrqllsor the like by which a transverse flange is first imparted to the sheet metal band and then this transverse flange is subsequently corrugated, by the action of a succeeding pair of rolls, therebyproviding a transverse flange adapted to compensate for thebending of the bandinto circular form, since the corrugations adjust themselves tothe decreasin circumfer ence of the inner portion of the transverse flange during the bending of the band. 1 While this method of forming bandsor rims has been satisfactory in many respects, the bands of this character mustbe completely formed before ap? plication to the tuber other container to be reinforced by them and the successive operations 1 which have been performed to form the flanges on the band and then corrugate them have involved considerable expense. As a part of the present invention, it has been discovered that the operations of the11prior11practice may be avoided and a bandprovidedwhich may be applied to-a tub or other container priortothe bending of parts thereof into position to form transverse corrugated flanges, thus greatly reducing the cost and permitting the application of corrugated bands to 1a variety of uses heretofiore impossible, with bands having :pre-formed transverse flanges. 1 1 1 1 1 1 The principal object of the invention is to provide an improvedimethod of forming sheet .metal or bands to permit the :formation of transverseflanges thereon after they have been applied to containers. A furtherobject of the invention is to provide an improved-methodofjforming an annular sheetmetal band having parts thereof capable :ofbeing bent transversely to form annu lar flanges without causing the buckling or overlapping of those portions of the metal. of the band which form the 'transverseflanges. y A further object of the inventionis to provide a butter tub orb-ther container comprising a vessel and a cover secured together by a band'having parts thereof bent inwardly to. f ormflanges which engage recesses or shoulders on the vessel and the coveni Another object .of theinvention is to. provide an improved sheetmetalband having one orjmore series of corrugations formed therein the use of the band illustrated in Fig. 7 in forming parts thereo fbent inwardlytoform flanges which versely. Other objects relate to various features of construction; and arrangement and to details of the method which will appear more fully hereinafter. 1 1 1 i 1 The nature of the invention will ;be understood from the following specification taken with the i accompanying drawings,- in which one example of the improved method is explained in connection with several embodiments of the improved band and container. 1 In the drawings, V 1 Fig. 1 shows a perspective view of g a plain 1 sheet metal strip or band employed in forming the improved bandor rim ;of the present in-1 ventiom U Fig.2 is a perspective view of the band illustrated in Fig. 1 after it has been provided with two series of corrugations along its longitudinal edges to permit the subsequenttransverse bend- 10 ing of these parts of thebandto form transverse flanges; 1 1 1 Fig. 3 is a perspective view of an annular rim or band adapted to be appliedto a butter tub or the like for securing a cover thereto; 1 25 V Fig. 4 shows a sectional view throughthe upper part of a butter tub, showing the application thereto of the band illustrated in Fig. 1 to receive a cover; 1 1 1 Fig. 5 is a sectional view similar to that of 3 Fig.4 taken on the line 55 of Fig.6, showing 3 the arrangement of the 1band after the upper series ofcorrugations thereon have been Ibent inwardly to form a transverse flange engaging a recess in the cover; 35
Fig. 6 is a perspective view of a butter tub embodying the features of the present invention and showing the arrangement of the parts after the band illustrated in Fig. 3 has been applied to the tub to hold the cover position 1 the1like;1 1
Fig. 8 is a sectional view through the upper part of a tub and a portionofits cover,*illustrating a rim for the cover adapted to extend downwardly about the upper part of the tub;
1 Fig. 9 isa perspective vlewshowing another form ofthe improved metallic band withtwo series sheet metal band 15 which is adapted to be oper ated upon to form a reenforcing rim orband for application to a tub or other container. In the practice of this invention, the band 15 is passed through suitable corrugated rolls to impart to the band two series of corrugations 15 and 15 which extend along the opposite longitudinal edges thereof, leaving an intervening plain portion 15 which is free of corrugations. The corrugated band thus formed may be carried in stock in long lengths and cut up to suit its application to a variety of uses according to which the corrugated portions of the band are bent transversely to the body portion 15 to formparts which are adapted to overlie or interlock with suitable parts of containers and their covers for securing them together. During the formation of the corrugations, the metal of the band is stretched to compensate for the increased length of metal which entersinto the corrugations and ithas been found that upon subsequently bending these corrugated portions at an angle to the bodyportion 15, the angularity of adjacent corrugations permits them to adjust themselves to transversebending, even when the band is in circular form, due to the contraction of the corrugations.
One important adaptation of the improved band illustrated in Fig. 2 is illustrated in Figs. 4, 5 and 6, where the band is employed for securing a butter tub and its cover in assembled relation. In forming this improved tub, a suitable length or" the band shown in Fig. 2 is bent into circular form and the overlapping ends of the band are then secured together by spot welding or rivets, as shown at 16, thus forming an annular rim 17. The portion of the band forming the series of corrugations is bent transversely to form aflange 18 and this bending of'the corrugated portion of the band may be performed after the formation of the annular rim 17, and the corrugations 15* then contract sufficiently to allow for the reduction in the diameter of the inner portions of the transversely bent flange. Having formed the rim 17 as shown in Fig. 3, it is applied to the butter tub 19, shown in Fig. 6, made up of a plurality of upwardly extending staves 20 secured together by annular bands or hoops 21 which are formed preferably of sheet metal and provided with beads 21 along their edges. The outer downwardly tapered wall of the tub is provided adjacent its upper edge with an annular groove or recess 22 which is undercut to form an annular horizontal shoulder 22*, as shown particularly in Figs. 4 and 5. The rim 17 in theform shown in Fig. 3, is applied to the tub by passing the inwardly directed flange 18 into engagement with the annular groove or recess 22, and this is accomplished by compressing the upper part. of the tub sufficiently to permit the band to be passed over the tub until the'flange 1'8' snaps into the recess 22. The rim 1? may preferably be passed upwardly from the bottom of the tub over the tapered wall thereof until the flange 18 is opposite the recess but this may be accomplished by compressing the upper partof the tub sufllciently to permit the rim to be moved downwardly from above and, with either method of application, the compressive force is released from the tub when the band is in proper position to permit the flange 18 to engage the recess 22, whereupon the rim is securely fastened to the tub and projects upwardly therefrom to receive the wooden cover 24 which is illustrated in dotted lines at 24. in Fig. i. The cover is then placed in position on the upper end of the tub and the uppermost series of corrugations 15 which have retained their initial arrangement in the plane'of the body portion 15 of the band, are then bent transversely to form an inwardly extending flange 25 which overlies the top surface of the cover and which preferably engages a recess 24*. formed around the edge of the cover, as illustrated in'Fig. 5. The completed band, as thus applied to the tub and its cover, is illustrated in Fig. 6, where the two flanges 18 and 25 formed on the rim engagethe annular shoulders on the tub and the cover to hold them firmly in assembled relation. By the provision of the series of corrugations in the band 15, it is possible for the tub 19 to be supplied to the users or consumers with the rim 17 applied thereto, as illustrated-in Fig. 4, and then, after the tub has been filled with the-commodity tobeshipped therein, the cover may be readily put in place and the upper series of corrugations of the band may be bent over the cover by a manual operation and the corrugations then adjust themselves to the transverse arrangement without causing any buckling or deformation of the metal of the band.
The improved method of forming the reenforcing rim or band, as described herein, is capable of application to other uses and to other forms of tubs or containers, among which is that illustrated in Figs. 7 and 8, where the band 26 is shown as being formed initially with a series of I transverse corrugations 26 along one edge thereof and a' bead 26* along the other edge thereof, with the intermediate portion 26 of the band free of corrugations or other irregularities.
After the band 26 has been formed as an annular rim 27, the corrugated portion 26 may be bent transversely toform an angular flange 28, as shown in Fig. 8, adapted to engage a butter tub cover 29 seated on a tub 30.- The cover 29 is providedwith an annular groove 29 bounded on its lower side by an outwardly and downwardly inclinedv annular surface 29 and bounded on its upper side by an annular projection or shoulder 29. The flange 28 seats on the inclined surface 29 and extends into the recess 29 beneath theshoulder 29, while the body portion T i of the band or'rim extends'downwardly around the tub 30 and may be secured thereto by nails or other suitable: fastening means.
In Figs. 9 and lothere is illustrated another application of the present invention according to which the sheet metal band 31 is initially provided with two series of corrugations 31 and 31' located along one edge of the band but separated from each other by an uncorrugated division line 31. After the complete circular band has been 7 formed, the corrugated parts 31 and 31 maybe bent transversely, as shown in Fig.9, thus forming a flange 32 extending inwardly from the body portion 33 of the rim, and another flange 34 extending downwardly from the flange 32. This form of rim may then be applied to the butter tub 35 and its cover 36, as shown in Fig. 10, where the annular downwardly extending flange 34 is shown engaging an annular downwardly extending recess 36 formed inthe cover inwardly from its outer edge, while the horizontal flange 32 overlies the top surface or shoulder 36 of the cover which is formed outwardly of the recess 36% and preferably below the level of the upper surface 36 of the cover. The body portion of the band extends downwardly around the upper part of the tub and may be secured thereto by nails or other fastening devices.
