 PATTEE V. MOLINE PLOW CO. 825 �the eud of the evener, and the whiffletrees are attached to the for- ward end of these two bars, where they converge into a hook, or other device, for attaching them. The claims of this patent, as reissued, which the defendant is alleged to have infringed, are the first, second, third, and fifth, which are as follows : �"(1) Two plow-beams, B B, connected together by an elevated beam-yoke, A, so that either may operate in advance of the other, while both are drawn forwaid in the line of progression by draft animais attached to each sida of the machine, so that each animal drawB in a manner its adjacent plow, the attachment of the plow-beams to said yoke being by joints which permit the moving of the beams freely and independently in a lateral direction, combined and operating substantially as described, and for the purpose specifled. �"(2) Two plow-beams, B B, connected together by an elevated beam-yoke, A, so that either may operate in advance of the other, while both are drawn forward in the line of progression by draft animais attached to either side of the machine, so that each animal draws in a manner its adjacent plow, the plows in an upright working position without rear connections or other sup- port, and permit of their being moved or oscillated freely in a lateral direc- tion, combined and operated substantially as described, and for the purposes specified. �"(3) Two plow-beams, B B, connected together by an elevated beam-yoke, A, so that either may operate in advance of the other, while both are drawn forward in the line of progression by draft animais attached to each side of the machine, so that each animal draws in a manner its adjacent plow, the attachment of the plow-beams to said yoke being by joints which sustain the plows in an upright working position without rear connections or other sup- port, and permit of their being moved or oscillated freely in a lateral or verti- cal direction, combined and operating substantially as described, and for the purpose specifled. �"(5) The draft-bars, F Y, hinged to the beam-yoke. A, and combined to operate with said beam-yoke and plow-beams, B B, substantially as described, and for the purpose specified." �It will be seen that the first claim covers the two plow-beams, con- nected together by a beam-yoke, so arranged that one may operate in advance of the other, and the plow-beams being attached to the yoke by joints which permit each beam to move freely in a lateral direc- tion, combined and operated substantially as described. In other words, as I understand and construe this claim, it is for a combina- tion of these plow-beams; the partioular and special kind of beam- yoke ; and the joints by which the plow-beams are hinged to the yoke, 80 as to secure the lateral motion. The second claim is for precisely the same combination of parts, with the additional statement that the joints by which the plow-beapus are attached to the yoke are to sup- ��� �
 * ittac)iment of the plow-beams to said yoke being by joints which sustain the
