METAL REcEr'rAcLn.
Application led September 18, 19252. Serial No. 588,767.
T o all whom t may concern.'
Be it known that I, CHARLES L. MooRuAN,`
a citizen of the United States, and a resident of thel city of Chicago, in the county of Cook and State of Illinois, have Yinvented certain new and useful Improvements in a Metal Receptacle; and I do hereby declare that the following is a full, clear, and exact 'description of the same, reference being had to the accompanying drawings, and to the numerals of reference marked thereon, which' form a part of this specification.
This invention relates to improvements in the construction ofsheet metal receptacles, with particular reference to ice cans of the type commonly used in the artificial ice manufacturing industry.
Heretofore, ice cans and similar coated sheet metal receptacles subject to severe service and exposure to conditions causing rapid rusting have been constructed with riveted joints, in some cases also having a clinched or folded seam. The process of riveting gives rise to serious manufacturing difficulties and forms a large number of breaks in the galvanized coating, thus eX- posing the sheet iron or steel to the action of rust by forming a starting point for oxidation. Moreover, the rivet heads on the inside of the can cannot give an even unbroken surface in contact with the contents of the can. With countersunk rivet heads a ring of exposed metal is left around the head where rust will form rapidly.
It is an object of this invention to avoid breaking the sur-face nf a coated metal receptacle at the joints.
It is an important object of this invention to provide a stronger and more durable form of joint than can be made with rivets.
It is another important object of this invention to (provide a new type of folded joint that is superior to various forms of riveted joints.
It is' a further object of this invention to devise a stronger and more durable joint that can be easlly assembled and which contributes to the economy of manufacture of articles in which the joint is used.
Other and further important objects of this invention will be apparent from the .disclosures in the accompanying drawings and specification.
The invention (in a vpreferred form) is illustrated in th'e drawings and hereinafter more fully described.
On the drawings:
Figure l is a perspective drawing of an ice can embodying a preferred form of the joint of this invention. I
Figure 2 is a top plan view thereof.
Figure 3 is an enlarged fragmentary view of a joint constructed in accordance with the principles of this invention.
'Figure 4 isa section on the line 4-'4 of Figure 3.
Figure 5 is a fragmentary perspective `view partly in sectio'n of one bottom corner of an ice can constructed in accordance with the principles of this invention.
As shown on the drawings:
An ice can constructed in accordance with the principles of this invention is shown in Figure l, wherein the sides of the can are formed of two identically shaped and interlocking pieces of galvanized sheet iron designated by the numerals 1 and 2. By forming the sides out of two pieces instead of four a better and vcheaper article is produced bythe elimination of two seams. The size of the larger ice cans in common use renders forming the sides thereof from one piece of sheet metal with only one seam impractical, but this can be done, for instance, with thel small 50,01` 100 pound capacity cans, producing a further saving in production time.
In forming a side joint according to the principles of this invention, the side piece 1 is bent at right angles as at 3 adjacent one vertical edge and a hook 4 formed on lthe bent portion 3. The other side piece 2 has a hook 5 formed on its corresponding edge adapted to interlock with the hook 4 as shown in Figure 4. As shown, the ends of the hooks, do not bottom in the bends of the mating hooks and the spaces so formed,l
right angle bend. After assembling the bent' edge ofpiece 2 in the hook of piece 1 the Whole joint so formed will 'be bent over into the position described above.
Under ordinary circumstances, the next step would be to punch a row of holes through this joint andto insert and head over rivets in the holes as in a hydraulic riveting machine. The process involved in this invention omits the rivets and holes therefor and uses a riveting machine with a smooth anvil and an ordinary rivet heading die to distort the folded material in the joint to lock the seam permanently. The die does not cut the sheet metal at all; it simply leaves a circular depression 6 therein on the outside which does not show on the inside in any way, because of the smooth anvil used. `While circular depressions are shown, it is of course understood that any form of depression may be made in the metal. As the metal is not cut at any point during this operation, the protective coat produced by galvanizing is not disturbed in any way, and therefore no starting place is provided for the destructive action of rust.
The bottom 7 is inserted in much the same way as the side joint is formed, except that the hook 8 provided on the sides 1 and 2 is flattened and no corresponding hook is provided on the flanges 9 of the bottom piece 7. Similar indentations 6 are formed along the bottom seams to lock them after soldering as before.
ll am aware that many changes may be made and numerous details of construction varied through a wide range Without departing from the principles of this invention, and ll therefore do not purpose limiting the patent granted otherwise than necessitated by the prior art.
I claim as my invention:
1. A sheet metal receptacle having an interlocking seam further secured by distortions at intervals in one side only of said seam.
2. A sheet lmetal receptacle having an interlocking soldered seam further secured by distortions at intervals in one side of said seam.
3. A sheet metal receptacle having an interlocking seam further secured by depressions pressed at intervals in one side only of said seam.
4. A sheet metal receptacle having an interlocking soldered seam further secured by depressions pressed at intervals in one side only o'f said seam.
5. A sheet metal receptacle having an interlocking seam further secured by distortions at intervals in the outside only of said seam.
6. A sheet metal receptacle having an interlocking soldered seam further secured by distortions at intervals in the outside only of said seam.l
7. A sheet metal receptacle having an interlocking seam further secured by depressions pressed at intervals in the outside only of said seam.
8. A sheet metal receptacle having an interlocking soldered seam further secured by depressions pressed at intervals in the outside only of said seam.
9. A receptacle of the class described, comprising suitable side and vbottom pieces, the joints therebetween formed by bending the edge of one piece into a hook, bending the mating edge of another piece outwardly at right angles, and inserting in the hook formed on the first mentioned piece, bending the assembled joint over to lieiat on the surface of the second mentioned piece, and indenting the joint so :formed on the outside surface at intervals to lock the same against movement.
10. A receptacle of the class described, comprising suitable side and bottom pieces, the joints therebetween formed by bending the edge of one piece into a hook, bending the mating edge of another piece outwardly at right angles and inserting in the hook formed onthe iirst mentioned piece, bending the assembled joint over to lie flat on the surface of the second mentioned piece, pouring solder into the joint so formed and indenting the joint from the outside surface at intervals to lock the same against movement.
lin testimony 'whereof ll have hereunto subscribed my name in the presence of two subscribing witnesses.
CHARLES L. MOORMAN.
