Description

L. B. WACKMAN Filed N01'. 28, 1932 fig@ METHOD OF MAKING CONTAINERS AND CHIMES THEREFOR Aug. 29,1933.
Patented ug. 29, 1933 Louis B. VJacknian, St. Louis, Mo.
Application November 28, Serial No. 644,653-
9 Claims. (C1. 11S-120) This invention relates to certain new and useful improvements in a method of making metallic containers and chimes therefor, this application being a continuation in part of my pending application filed February 2, 1932, Serial No. 590,426, on unitary chime for metallic containers, now Patent No. 1,839,505.
The primary object of the invention is in providing a chime for a metallic container from a single sheet of material. Y
Another object of the invention is in providing a chime for a container which is made of a single material sheet beaded in a manner for forming and a retaining flange for the -e cover.
A further obyect of the invention is in forming a chiine for a container of a one-piece construction with an improved form of reinforcement thereto.
A still further object of the invention is in providing a specific method of bending and forming the upper or top. portion of a container wall into a chime with means on the chime for providing both a cover seat and a retaining flange for the locking ring of the cover.
Other and further objects will appear in the specication and be specifically pointed out in the appended claims, reference being had to the accompanying drawing, exeinplifying the invention, and in which:-
Figure l is a fragmentary sectional view of the upper portion of a metallic container showing the chime construction formed by this improved method, the chime being shown as forming a drawing, and particularly with reference to Fig.
1, the numeral 1 designates a side wall of a rne-l tallic container made from a single sheetof material and formed integral with the upper end of the side wall is the chime 2-formed by this irnproved method.
The chime 2 after beingformed `by this irnproved method, is provided with a gasket' and cover seat 3 and a retaining flange 4;
The seat 3 of the chime 2 is for the reception of an annular gasket 5 on which the flange 6 of a cover 'I is mounted, said cover having a depressed center portion 8 which isengaged Within the confines of the seat 3. 'In securing the cover to the contain 1 n a sealingrnanner, a split locling ring 9 which is angular shape in crosssection, is engaged so that the horizontal leg 1U thereof willbe forced between they flange 6 of the cover i and the retaining flange 4 of the chime 2, the wedging actionof the leg 10 ofthe ring 9, causing the ilange 6 of 'the cover to compress the gasket 5 on the seat 3.
A container having a chime of this improved character is primarily used for shipping semisolid liquids, grease or dry materials.
The method of constructing this improved chime 2 .is started while the material is in a flat- 7 secured in some manner to theupper end of the 7 side wall of the container.
The first operationin carrying out this improved method, is to engage one end of the material sheet 11 in a bending or folding device such as a power folder for the'purpose of bending a portion 12 rearwardly on the material sheet in a lapped position as shown in Fig. V2.
The nextl operation is in engaging the folded material sheet in a set of power forming rolls for rolling the folded material sheet in a cylindrical shape with the lapped portion 12 at one end of the cylindrical body. After the cylindrical body is made, the contacting or meeting edges lla of the material sheet are welded.
The-cylindrical body is then engaged with its lapped end in position for being operated on by the cooperating grooving or beading rollers 13 and 14 of a power beadingrnachine for forming an annular grooveor channel 15 on the outside of the cylindrical body. In forming the channell, the channel forming projection 16 of the roller 13 is positioned in engagement with the depending end 12a of the Voutwardly folded or lapped part 12 so that the depending end 12a will be forcedin thechannel l5, as shown in Fig. 3. v
The cylindrical body having the groove or channel 15 formed therein on the outside thereof is then engaged between a different set of cooperating rollers 17 and 18,'the roller 18 having an annular groove 19 which is narrower in width than the annular groove 20 of the roller 14 and the roller 17 having an annular projection 17a for engaging the lapped part 12 while the groove 19 ofthe roller 1S over-engages opposing walls of the channel 15. Therolling operation of the rollers 17 and 18 will cause the channel 15 to be narrowed, as shown in Fig. 4.
The next operation is in engaging the lapped end of the cylindrical body between a pair of cooperating rollers 21 and 22, the roller 22 having an annular groove 23 which is narrower in width than the groove 19 of the roller 18 and the roller 21 having a flat face, the operation of the rollers 21 and 22 causing the opposing walls 24 of the channel l5 tobe tightly pressed against the depending or free end 12a of the lapped portion 12, as shown in Fig. 5. The walls 24 of the channel l5 form the gasket or cover seat 3 and the cover seat is reinforced by the engaged free end 12a of the lapped portion 12 therebetween.
A different set of cooperating rollers 25 and 26 is used in completing the nnal operation of forming the chime and in this operation, the retaining flange 4 is made and for forming the retaining flange 4, the roller 25 is provided with an annular extension 2'.' for engaging and operating on the upper or outer portion 28 of the folded or lapped portion 12 for rolling the upper portion 28 into right angular position above the seat 3, as shown in Fig. 6. During this operation, the groove 29 of the roller 26 is engaged over` the seat 3 and the annular portion 30 of said roller between the seat 3 and the portion 28, cooperates with the annular portion 2'7 of the roller 25 for forming the retaining flange 4 and the connecting wall 32.
After the several operations above described, it is obvious that an improved unitary chime of a one-piece construction is provided, the peculiar bending of the sheet material providing a strong and durable construction for securing the cover 7 and its gasket 5 in sealed position on the seat 3 of the container by firmly holding the locking ring 9 in cooperation with the retaining portion 4 of the chime andthe cover.
The disclosure of Fig. 7 is similar to that shown in Fig. 6 with the exception of a U-shaped reinforcing layer 31 being interposed between thel overlapped portion 12 and the material sheet 1l, thus forming a heavier and stronger chime, if desired. In the use of the layer 31, said layer is interposed between the lapped portion 12 during the bending thereof at the rst operation.
Obviously constructional modifications of this improved method are possible without departing from the spirit of the present invention and therefore it is to be understood that it is not necessary to limitthe invention by the terms used in the foregoing description, excepting such as the stateA of the art may require.
What I claim is:-v
