IMPROVEMENT iN` METALLIC cAN-BoTToMs.
Specification forming part of Letters Patent No. 98,5
26, dated January 4, 1870; Reissue No. 4,032. dated June 14, 1870.
To all whom it may concern:
Beit known that HENRY W. SnEPAED, of Mannsville, in the countyof Jefferson and State of New York, invented certain new and usewhich Letters Patent of the' United' States lwere granted bearing date January et, 1870, and numbered 98,526; that one-half interest` in said Letters Patent has been assigned by HENRY W. SHEPARD to ROBERT SEAMAN, of New York city,in the county of New York and State of New York; and that the following is a full, clear, and exact description of said invention, reference being had to the accompany' ing drawing, and to the letters of reference marked thereon, making part of this specification, in which is represented a horizontalv vertitl section of the can-bottom.
The nature ofthe invention, and which isa a metallic can -bottom in one piece, whether by stamping orotherwise. The surface or base of the bottom is to be convexed or curved and surrounded by a. vertical annular rim.
The advanta ges of this construction will readily suggest themselves. Owing to the arch shape of the .bottom resulting from its convexed or curved formation, the requisite strcn gth is secured without rendering the bottom unduly heavy, while the 'vertical annular rim affords a convenient and permanent support for the base ofthe cylinder or body of the can, and one to which it can readily be attached.
To enable others skilled in the art to make and use the invention, we will now proceed to describe its construction and operation.
'A is the bottom, lmade in one piece and of any suitable metal. We usually stamp them out of iron plates or sheets known to the trade as No. 16, which possess the requisite strength, and are of adequate weight to retain the can in avertical and steady position when being transported in an empty condition. The surcleimly shown in the drawing. The degree of this convexity maybe slightly varied. The advantages of this convexed over any other form are twofold; rst, the arch formation insures the desired degree of stren gth without being unduly heavy or cumbersome; and,
again, it forms at its point of union with the rim or flange A an open recess, a, which is most desirable, and in which is seated the cylinder B. The rim or flange A2 is vertical and perfectly straight, so that when the cylinder is inserted and secured a can of uniform diameter throughout shall result.
B is the cylinder, andis made in the usual manner and of suitable metal. lt is seated in the recess af and firmly secured by rivets a a and solder.
It will be observed by reference to the drawing that the bottom, rim, and lower section, b, of the cylinder are entirely protected by the heavy metal bottom., .the flange A2 not onlyaffording a convenient bearing-surface for the cylinder to be attached to, but also furnishing a strong hatdanetallioomso that whenthe cans are pushed together the seam-joint is not only entirely protected, but no portion of the cans save these flanged hoops can come in contact; and as these are of such material as not to be bruised or indented, all danger of injury to the can is avoided. The great advantage of this open recess a is found in. the fact that the can, after being emptied, is so readily cleaned, and can thus be always kept perfectly pure. The iron bottoms thus formed are tinned by the usual process.
Having thus fully described the invention, what is claimed therein as new, and desired to be secured by Letters Patent of the United States, is-
As a new article of manufacture, the can-bottom A, when constructed in one piece, consisting of the curved surface Al and vertical auf nular rim A2, substantially as described.
In testimony whereof we have signed vour ing witnesses.
face A of the bottom is of convexed form, 4 H' W' SHEPARD* ROBT. SE AMAN.
Witnesses En. P. GODDARD, S. D. CLARK.
