To facilitate this action, in each of the cup- In the accompanying drawing, A is a dies is loosely mounted flat holding plates 50 suitable framework upon which the moving E CHIIIGdDIFthG sliding rods E held. re- 1 partsof the machine are mounted, B, B tracted by sprlngsE Each of the metallic arecarrierfchains provided with suitable cup like dies is provided with means for shaft B by a guide chain H sist of an electric resistance coil F. The oppositely moving pair of dies are connected to a suitable moving framework G mounted on rods Gr sliding through ways Gr carried on the stationary frame of the machine at each side thereof. The intermittent move ment of the airs of dies "toward each other is accomplished in the instance illustrated by the links H, the bell cranks H the pitman rod H and the cam H mounted on the shaft H and actuated from the main power The adjustment and time is such, as indicated in the drawing, that the loosely headed can bodies are fed by the feed chains intermittently step by step until the first one reaches the position of the, first pair of holding and heating dies. Here the can body stops momentarily and the pair of heating dies close upon it in opposite directions, forcing the heads or ends firmly upon the'body and holding them momentarily there in the heated dies, after which said dies separate away from the can bodies and from the holding plates E leaving the headed can with its heated heads free in the feed chains. The feed chains now move another space bringing the can. into position opposite the second pair of dies which may preferably be a closer approximation to the final shape and the next succeeding can into position opposite the first pair of dies when the operation of compressing, heating and releasing is repeated. This operation is thus continuously repeated until all of the cans are fed through the machine and discharged completely headed at the other end of the machine with the heads fitted and shrunk smoothly in place. By thus operating several times successively by different pans of dies upon the same can, the total time of the heating and drying action is multiplied, without cdrrespondingly multiplying the length of time required for feeding the cans through the machine. And when the pairs of dies are made successively more nearly conformed to'the final form required, they operate gradually to shape the heads to such final form. The intervals of time during which the body and heads are released from the dies serves to permit .the free escape of vapor from the moist heads and thus to facilitate the ultimate and complete drying and settin g of the material.
