IMPROVEMENT IN CONSTRUCTION OF FRUIT-CANS.

Specification forming part of Letters Patent No. 105,109, dated July 5, i810; reissue No.'4,735, dated February 6,1872.

I, Join: F. MERRILL, of Cincinnati in the county of Hamilton and State of Ohio, have invented a certain new and useful Improveential groove crease, or channel,which-is formed in the b0 .y of the can, and when the latter has been expanded by any suitable implement, so as to cause its crease to hug the inner flange of the rim, and the body of the can soldered,

said sealing-trough is immovably secured in position.

Figure 1 is a perspective view of the rim, the unsoldered body of the can, and the bottom of the same, these threediiferentmembers being detached. Fig. 2 is an axial section showing the manner of applying the rim and bottom of the can to the body, and also the implement by which the latter is expanded, so as to cause its crease to hug the flange of the sealing-trough. Fig. 3 is a side elevation, showing the expanding implement fitted within the can, and the latter in condition of soldering. Fig. 4 is an enlarged sectional view through the upper part of my fruit-can.

A, B, and 0 represent, respectively, the rim,

the body, and the bottom of a fruit-can embodying my improvements, the bottom having the customary upturned marginal flange c, and the sides of the can being either parallel or converging toward their lower ends, the latter form being preferred. The rim A is composed of a single annular piece of sheet metal, which is struck up in such ainanner as to have a depressed portion, a, which constitutes the seal in g-trough proper, and an inner flange, D, which can project either up or down, as may be found convenient. The outer circumference is sti fened by a swell, E. The body of the can has turned in it, near its upper end, a groove or recess, or channel, b', whose depressed portion is presented toward the outside of the can.

In order that the rim and bottom may be unite'd'to the body of the can in a secure, uni- 7 form, and expeditious manner,'and with the least expense, I adopt the following mode of construction: I provide a stand, F, which is open at top, and suitably supported, and whose length is equal to the desired height of the sealing-trough. I then drop into this open mouthed stand the bottom 0 c of the can, after. which Iapply the rim A in such a manner that its outer swell 'E will rest upon the upper end of said stand. The .u'nsoldered sheet of metal -B, which is to compose the body'of the cani after being properly formed, is then inserte within the rim A and the flange c of the bottom. I then force down within the body of the cane tapering plug or plunger G, which expands the piece of sheet metal This insertion of theplunger G forces out the bottom of the can against the flange c, and also, expands the upper part of the can in such a manner as to cause its crease b to hug very tightly the inner flange D of the rim A. In this expanded.

condition of the can, it, with the adhering bot-' tom and rim, islifted bodily from the stand, and the sides of the can andbottom soldered. The rim thus attached may be soldered to the body if preferred, although it is not necessary. After soldering the sides and bottom of the can, the tapering plug Gr is easily withdrawn by the aid of its handle 9. p

In manufacturing small cans awooden plug' may be employed; but for large cans, where the weight of the wooden plug might be objectionable, a sheet-metal one can be substituted therefor.

By referring to Fig. 4 it will, be seen that,

I claim as my invention- 3. The stand, when used in combination with 1. The body B, having the circumferential the plunger in the formation of the body and. crease b, in combination with a corresponding trough of afruit-cen,substantia1iy as set forth.

curvature in the rim A, constructed substanr JOHN F.'MERRILL. tially as described, for the purpose set forth.
