 360 FEDERAL REFCRTEH. �tion formed by the joint to be closed; the object of this part of my invention being, in the case of angular eans, to perfect the corners or angles at the top or bottom of the can simul- taneously with the closing and clamping of the en tire seam at the top or bottom of the can, and to produce thereby a more perfect joint than can be obtained in machines in which the top and bottom seams are closed by clamping jaws which, bearing only against the sides of the head, do not embrace the corners or angles thereof." �There are four claims in the re-issue, but claim 3 is the only one alleged to have been infringed in this case. It is in these words : "3. In combination with an intermediate fixed or movable supporting plate or anvil, angular clamping jaws, adapted to be moved against the angles or corners of the pro- jecting end seams or joints of a rectangular sheet metal can plaeed thereon, and formed to embrace said corners, and to close and clamp between them the entire end seams or joints of the can, ail substantially as herein set forth. " �Figure 1 of the drawings annexed is stated to be a view in perspective of one form of machine embodying the inven- tion, the clamping jaws of which have a vertical movement, the machine being adapted to close and clamp simultane- ausly the joints of both ends of the can. Figure 2 is stated to be "a view in perspective oi a can, with its heads in ends plaeed loosely therein, ready to be closed and clamped." Figure 4 shows the clamping jaws opened and figure 5 shows them closed upon the joint or seam of the can. The specification states that the clamping jaws, of which there are two of each kind, are arrangea to meet in pairs, one of each kind making a pair, the two lower ones in a vertical machine being alike and the two upper ones in a vertical machine being alike; that each of the four is shaped or eut out to form a notch, a, "to embrace, and fit closely and accurately, upon a section or portion of the joint at the end of the can, " so thaï r/hen the two in a pair are brought together they will include and cover the whole joint, and bear evenly upon every point thereof. �In the vertical machines shown in the drawings the lower ����
