UNITED STATES HENRY OALLAEAN, OE DAYTON, OHIO.

IMPROVEMENT IN FRUIT-CANS.

Specication forming part of Letters Patent No. 118,586, dated August 29, 1871.

To all whom it may concern:

Beit known that I, HENRY GALLAHAN, of the city oi"Dayton, county of Montgomery and State of Ohio, have invented certain Improvements in Manufacture of Preservingans, of Which the following is a specification:

This invention relates to the construction and arrangement of the rim or flange at the top of preserving or fruitcans made oi' sheet metal, that cans may be provided with a groove exterior to and below the mouth of the same for the reception of cement, forming a complete open-top can, the ila-ngc of the cover passing over the edge of the can and descending into the groove when the can is to be sealed. It consists in forming from a narrovT strip of metal, by pressing or swaging, an indented or corrugated flange or ring, Which, when placed in proper posit-ion below the mouth ofthe can and soldered fastthereto, With its en ds joined, constitutes a projection of the top of the can over which the flange of the cover may pass, and forms a groove or receptacle, exterior to the can, for the cement required to seal up the can.

I am aware that cementgrooves have been formed about the mouths of metallic cans in a variety of ways-for instance, by folding the edge ofthe mouth of the can itself, as shown in Figures l and 2; again, by cutting acurved strip of metal, Which, Wh en placed upon the can with its ends soldered, forms a flaring iiange, as shown in Figs. 3 and 4, and the plan in common use, bein g to cut from a sheet of metal a round ilat piece, as shown in Fig. 5, which, when formed in a die and soldered tothe can, constitutes the ccment groove, as shown in Fig. 6. The iirstnamed of these plans is objectionable because it is very difficult to form the groove in the manner indicated. The secondnamed plan is Objectionable, as it is not easy to Work; the strip of metal not being pressed or sWaged makes it difcult to retain it in proper position While being soldered on the can. The last-named plan is objectionable on account of the Waste of metal and of the expense and labor required in making the same.

By my plan an equally good result is attained at a very much less cost, there being no Waste whatever of metal, and there being less labor required in making and'applying it. This plan is shown in Figs. 7,8, 9, and l0.

That others may fully understand my invention, the following is a particular description:

A sheet of metal is first cut into narrow strips. The strips thus formed are pressed or swaged, by the action of proper forming-rollers, dies, or other tools, and corrugated so as to form a concave flange, a section of which is shown by Figs. 9 and l0.

These corrugated strips, made in the manner described, are manufactured as an article of trade, to be used by the manufacturers of preservingcans by placing them around and near to the top of thc can, and then soldering them at the ends and to the can, so as to form a hoop or ring around the top of the can, making a groove for the receptacle of cement, Sac., as shown in Fig. 6, these corrugated strips being furnished and used by the manufacturer at a much cheaper rate than it is possible to manufacture the circular lianges made solid, as shown in Figs. 5 and 6.

Having described my invention, what I claim as new is- The hereindescribed corrugated cement-ring, made from strips of metal joined at their ends, in contradistinction to the solid ring, substantially as described, as a new article of manufacture and trade.
