Definitions
- Figure l represents a side elevation of the machine.
- Fig. 2 is a plan View of same, and
- Fig. 3 is a longitudinal vertical section through line w of Fig. 2.
- Myinvcntion consists in so constructing and arranging a gang or series of plows in one frame that they may have an adjustment on the supporting-runners, and a means of selfadjustment vertically, so that they may be set for furrow-slices of any given depth, and any one of the series may give way to an undue resistance in the line of the furrow without disturbing any others of the plows. It also consists in a means of limiting the horizontal or lateral vibration of the revolvingv colter or cutter disk.
- a A are two substantial runners, for supporting the entire plow or series of plows, preferring runners to wheels, for ⁇ the reason that they will not dip into depressions in the ground, and thus allow the plows to run into the ground beyond their stipulated depth.
- B B are front and rear cross-pieces, for uniting thetwo runners, and thus making a firm frame for sup-v porting the gang of lplows.
- the plows H H H H, ⁇ dto., of any suitable form, are hung to these beams F,'and the shares of the plow or their mold-board may be so arranged as to turn all the furrows to one side, or part to one side 'and part to the other, as may be desired.
- Vwhich cutters have a front support or guide, i, to direct their course.
- Braces k extend across from the .side pieces K K, which arev bent around the stem or stock J of the cutting-disk, to give additional support to the machine by binding it together transversely, thus adding much to the strength of the frame in resisting lateral or side strain. These braces k perform another important funct-iou.
- brace k could not be used to limit the lateral vibration of that cutter-disk by reason of its close proximity to the forward cross-tie of the frame of the machine, but which does not depart in its principles of operation or application to brace k, and is simply two iron or other pins driven into the cross-tie of the frame, one on each side of the stock J, allowing the bent arms that contain the cuttingdisk to strike against the pins, producing the same ei'ect as does the bent brace k, and is regarded as being, the same invention.
- levers L M At both the front and rear of the plow-frame are two levers, L M, having their fulcra at n.
- the point of the lever L bears against the outside point of thelever M, and behind M is a spring, m, and in each of said levers is a pin or bolt, o, which passes into andl through holes in the uprights C, and into the cross-beams E E', to hold them in place when adjusted.
- the Asame motion causes the lever M to draw out its pin. Then, by throwing out the pawl e from the ratchet d, and turning the crank c, the cross-beam may be raised or lowered at pleasure, carrying with it the series of plow-beams F, which rest on it. By this contrivance the depth of the furrow is regulated.
- the plow-beams F have a self-adjustment at the rear, they only being controlled from rising too freely or too high by the weights G; and, although they may rise to yield to any obstruction, they cannot drop below a given distance-that is, lower than the cross-beam E', and are thus prevented from allowing the plows to run into the soil.
- Any number of plows may be used within the capacity of the team or power which draws it.
- bent brace k when constructed in the form as described, and attached to the frame of the plow, inthe manner and for the purpose substantially as described.
