643 FEDERAL REPORTER. �* * * Upon anaxle, A,supportedm[on] theusual canying wlieels, BB, is mounted a main frame, C, and on the main frame a seed-box, D, the slides of which may be operated in any of the well-known ways. In bearings, E, in the front portion of the main frame, is hung, so as to rock or turn therein, a zigzag or crank-shaft, F, shown detached in figure 2, and to the oranks [crankj or wrists, aaa,ot this shaft, are connected, seriatim, the drag-bars, 6 6 6, by means of bows or yokes, c, each bow or yoke taking two of said wrists, as shown In figure 1. To the rear ends of these drag-bars, 6, are attached the shoes or hoes, G, in any of the usual well-known ways. In the projecting rear portion of the main frame, C, there is hung a shaft, d, upon which there is a lever, e, by which it can be rocked or rolled in its bearings. At suitable distances upon this shaft, d, there is placed a series of levers, //, one for each shoe or hoe, which are kept in their proper positions on the shaft by pins, T T, or other suitable devices, but which can be moved independent of the shaft, or of each other, or all togetiier, as will be explained. The levers /, have a hub or swell, g, at their central portions, where they are slipped onto the shaft, d, and into each one of these hubs is set a pin, 2, which is above the pins, T T, in the shaft, so that each lever can be turned upon the shaft ; but when the shaft is rocked or turned, then all the levers are worked simultaneously. To the forward ends of these levers, /, the shoes or hoes are respecUvely connected by a link or hinged rod, h, the rearward projecting ends of said levers serving as handles for the operator to seize and virork sep- arately, when necessary todo so, or he can raise the whole series by seizing and working the lever, e. One end of the shaft, d, projects through the tiinber of the main frame, for conveuience of placing the parts, and upon it is a lever, H, and a spring-locking lever, i, connected wlth it, both of which lev- ers the operator may grasp at once, and by pressure, flrst unlock the catch and then move the main lever, II, and the shaft, d, as well as the parts con- nected with it. The catch or locking lever, i, locks into or against a [the] stop- plate, J, on the main frame, when not other wise controlled. The upper por- tion of the lever, H, serves as a handle to work it by, and to the lower end of it is pivoted a rack-bar, [or conuecting-rod,] m, which takes into a pinion, n, fastened on the end of the crank or zigzag shaft, "F, and when the pinion, n, is turned, the crank-shaft is also turned, and as it is turned it shif ts the shoc j or hoes into a zigzag or a straight line, as the case may be. When the lever, H, and the zigzag shaft, F, [and the Connecting bar, m,] and their several connected and operative parts, are in the positions shown by the black [f ull] lines in figures 1 and 3, the shoes or hoes. G, are then in a straight line across the machine; but when the lever. H, is shifted into the position shown by the red [dotted] lines in figure 3, it turns the shaft and moves the parts connected with them, and the shoes or hoes will then stand in a zig7,ag line across the machine, as shown by the red [full] lines, or in what may be termed two lines, one in advance of the other, and [in order] that the shoes or hoes may be thus moved into one or two lines, and still be susceptible of being raised up sepa- rately, or in their series capacity, their connections and [the] attachments must all be hinged or yielding. When there is an odd number of shoes or hoes on the machine, the odd one should be in the rear series, in which case there would be no necessity of locking the lever, H, when the shoes were [are] so ��� �
