Indeed, it seems to me that Schroeder's "arched beam-yoke" and Pattee's arched and jointed axle are fully anticipated in form of construction, function, and mode of operation by Pratt's "curved metal bar, H." And it is also noticeable that Pratt claims these characteristies as the pateutable features of bis devices, while they were not originally claimed (or at least allowed to them) by Schroeder, Eichholtz, Nor- ton, or Pattee. �In 1865 W. S. Weir attached the plow-beams of bis cultivator to an arched axle, as shown by the proofs, by a two-way joint, whieh held the plows in an upright working position without rear connec- tions, and permitted all the lateral and vertical motions claimed in the Schroeder patent; while Adam Young, in November, 1866, and George E. Owens, in August, 1871, show the two plow-beams of a straddle-row cultivator connected together by an arched yoke with a joint in the middle, and for substantially the same purpose as used in Poling's deviee. Young says in bis specifications : �"In order to arrange the connections between the plows so as to pass over the tops of corn leaves, after the latter have coiisiderably advanced in growth, as is always the case with the late or final plowing, the Connecting beams between the two plows are constructed in a peculiar manner by taking them in a vertical direction above each beam, and conducting them horizontally across towards the other plow. ihere are two of these bent beams attached to each beam, and to each other in the horizontal part of them, so as to form a pair. Each pair of these beams is coupled together by a peculiar clamp arrangement, which admits of a ready adjustment of the parts to aecommo- date the width of the rows as before recited. * * * �"The sockets, a, are permitted to tum eaaily around thcir vertical axis so as to allow one of the plows to be drawn ahead of the other without wrench- ing or straining any of the parts, and the beams, C C, are pivoted to the sockets, a, or the handle, B', so as to allow the requisite lateral motion of these parts." �Owens, in 1871, describes a tongueless straddle-row cultivator with an arched beam-yoke jointed in the center by a ring, and he says that this arrangement permits one section or division of the imple- ment to be eight to twelve inches in advanee of the other. There is then shown, by the proof in this case, that at times long antedating all of the complainants' patents all of the ideas or peculiarities of the complainants' several machines — the arched yoke of Schroeder ��� �
