 650 FEDERAL REPORTER. �hinged to both its drag-bar and its individual lever, so that it can be laisod or lowered, in either of its changed positions, by a lever that is pennanently lo- cated, substantially as described. (6) In combination with a series of shoes or hoes that are capable of being changed by the operator at the rear of the machine from a straight to a zigzag Une, or vice versa, a shaf t and lifting lever conneeted therewith, whereby the vrhole series can be raised at once by the operator to pass obstructions, substantially as described." �The claims of the original patent were three in number, as follows : �» (1) So attaching the shoes or hoes of a seed-planter to the main frame, as tuat by means of a lever, or its equivalent, said shoes may be shifted from a straight to a zigzag liiie, or vioe versa, at pleasure, substantially as described. (2) In combination with a series of shoes or hoes that are capable of being changed from a straight to a zigzag Une, or viee versa, the So Connecting of aaid shoes by independent levers to the lifting-bar, as that they be raised by the operation individually or as a whole, substantially as described. (3) Hing- ing the shde to both its drag-bar and to its individual lever» so that the shoe may be raised and lowered, in either of its changed positions; by a lever that is permanently located, substantially as described." �Claim 1 of the original is substantially the same as claim 2 of the re-issue. Glaim 2 of the original is substantially the same as claim 4: of the re-issue. Claim 3 of the original is substantially the same as claim 5 of the re-issue. The original specification stated that there were two objects in the invention. One was stated to be to shift or change the seeding shoes or hoes from' a straight to a zigzag line, or vice versa. It is plain from the text, and from the meohan- ical construction of the apparatus, that the shifting was to be done by the operation from the rear of the machine, and without stopping the machine, and that all the shoes whieh were to be shifted were to be moved simultaneouslj and not successively. �The particular method shown was to have in the front part of the machine a turning-shaft, with'cranks on it so arranged that the shaft did not have a straight, continuons axis, but had sets of axes in dif- ferent linesj alternating, so that yokes being attached, each to two of the cranks, and each two of the cranks having axes in a different line from the line of ihe axes oi the next two adjoining cranks, the yokes being of substantially equal length, and being conneeted by drag-bars at llie rear enda of the drag-baxs to the shoes, a rotating movement given to the crank-shaft would shift the shoes by moving all of them, each alternate shoe moving in an opposite direction from the direction in which every other alternate shoe moved, and thus a space being opened or closed of double the distance thi:ough which any shoe traveled, ihe particular method of producing the shift- ��� �
