Specification forming part of Letters Patent 'hlo. 86,356. dated July 25,1876 yappli'cation tiled June 23, 1876.

To. all whom it may concern Be it known that l, FELlX tinnounr, of Etel--Morbihan, in the Republic of France, have invented certain improvements in the lllanufactureof Metallic Boxes or (lane; and I do hereby declare that the following is a full, clear, and exact description of the same, referwhich forms part of this specification.

One of the objects of this invention is to produce hcrinctically-scaled cans or boxes for preserving fruits, meats, and other articles or suit stances without resorting to the use of solder for closing the joints formed by the junction of the ends of the box or can with its body. For this purpose 1 suite the cover and bottom or ends of a metallic box. ores-n with the body thereof by a process of setting said ends in and uniting them with the body by an outside joint, requiring neither lire nor solder to close it, but which is closed by a series or succession of bending-and foldingoperations in dies, by a direct pressure or action.

The invention consists in a certain combina tion of peculiarly constructed dies for thus successively operating on the ends of the body of the box or can, and on the edges of the cover, fitting the some to close the ends of the can by direct pressure of said dies orsaid end and edges. The joint thus formed is on the outside of the can; and toinsnre its ctfectnell closing it is proposed to incorporate with said joint a soft or iii lible interposed strip", having an insoluble coating applied to it, as well as to the metallic portions of the joint. 7

, Figure l is a vertical section, of a pair of dies, in part, used in the preliminary stage of the work. Fig. 2 is a vertical section, upon 'a smaller scale, of a means or apparatus fitted with like dies, but showing the latter as closed on the work and Fig. 3 a horizontal sec ion on the line as Fig.4 is a vertical section,

and when closed. Figs. 5*and-G are vertical sections of a succccdin g pair of dies, in part, in their open and closed conditions. 'Fig. 7 is a further like view of another and following pair of 'dies,-'in part, used in the production of the or. finishing pair of dies as in the act of closing the joint.

Referring to the accompanying drawing, I first take the body A of y the metallic box or can and dip its opposite endedgos successively 1 in strong glue or other analogous substance,"

dissolved in acetic or-pyroligneous acid. This forms a coating, which is allowed to dry, and

.matcrially assists in forming the joint, irrespective of the shapo or construction of the latter, inasmuch as it not only protects the joint against being attacked by oil or other matter forming part of the conteutsof the can, but insures absolute tightness for the joint. i

' The means usedfor fitting on the body of the can its bottom and top or end eoverssuccessivelyconsist, in part, of a body metal holder or frame, B B, which may be made in halves or sections, hinged together longitudinally, to provide for the entry and removal of the can. At the bottom of this frame isa spring,.0, which serves to raise. the box or can after-each joint forming or closing action of an upper die, as hereinafter described.

011 the upper part of the frame'B B is a steel ring or lower die, D, madein the form of a gutter orledge, the raisedportion I, of which serves, in conjunction with an upper movable die, E, to bend over the upper exposed and of the can-body, and to give proper form or direction tea. soft or flexible strip 0! band, G,

placed around the body of the can; at least i to fit t'reely over and receive withinit the upi right portion b of the lower die D, whichportion is made slopingflownward in an outwarddirection on its upper edge, and'the portion or surface a of the upper die which lies over said edge of the lower die is made to correspond,

but longer, so that as the two dies come to-
