AUXlLlARY MOLDBOARD, 800.

SPECIFICATION forming part of Letters Patent No. 503,413, dated August 15, 1893.

Application filed October 19, 1892. Serial No. 449.341. (No model.)

, has been removed, the ordinary mold board remaining in place, which attachment en ables an ordinary plow to be used successfully in the cultivation of small plants, the auxiliary mold board enabling the plowman to place the earth around small plants without danger of either injuring or covering them, the ordinary mold board serving to balance the plow.

The invention consists in the novel construction of the auxiliary mold board and the relation which it sustains to the ordinary mold board when the latter acts as a seat for it, as will be hereinafter fully set forth and pointed out in the claims In the drawings the ordinary mold board of a plow is shown and designated as A. The seat or fork upon which the point of the ordinary mold board rests is designated as B. The attachment comprises a mold board 0 and a point D, the two heingintegral although they may be attached one to the other in any suitable or approved manner.

Figure 1 is a plan view of the auxiliary mold board and point applied to an ordinary mold board of a plow. Fig. 2 is a side elevation of the auxiliary and the ordinary mold boards, illustrating their relation to each other. Fig. 3 is a vertical section taken practically on the line 3-3 of Fig. 2, illustrating the difference in the transverse formation of the two mold boards; and Fig. 4 is a bottom plan view of the ordinaryand auxili ary mold boards, showing the manner in which the two are connected.

In the drawings an ordinary mold board of a plow is shown and designated as A, and the toe of the mold board is designated as B, the

toe being that portion to which the ordinary point is secured. The attachment comprises a mold board 0 and a point D, the two being integral although they may be attached one to the other in anysnitable or approved manner.

The prime feature of this invention, as has been heretofore stated, lies in the peculiar transverse curvature of the auxiliary mold board 0, in the sweep of that board, and in the overhang of its upper edge. The auxiliary mold board 0, is of much less height than the ordinary mold board, and the transverse curvature of the board is much more decided, its frontconcaved face being very pronounced, as is shown at- 10 in Fig. 3, in which the curvature of the forward end of the auxiliary board is placed in position to contrast strongly with the corresponding face of the main or ordinary mold board A; and from this view it will be observed that the auxiliary mold board, while following closely the shape of the lower edge of the main or ordinary mold board, leaves the latter board at or near its center, and is carried outward with a sweeping curve from the main or ordinary mold board. This curve is most decided at the rear end of the auxiliary mold board; in fact the curved surface 10 is graduated in such mam nor that the upper edge of the auxiliary board, or that portion which may be denominated the overhang of the main board, which is designated as 11 in the drawings and is shown mostdecidedly in Fig. 1, is quite narrow at the forward edge of the mold board and gradually increases in width until it terminates in quite a wide and decided outer side slant at the rear end of the mold board, whereby when the auxiliary mold board is viewed from the top the outer and inner lines are quite removed at the rear end of the mold board but unite in the line defining the forward edge. By imparting this contour to the auxiliary mold board, the earth when received by the board is turned in a gradual manner, and as the plow advances while the soil is in the act of being turned, the earth is deposited close to the plants being cultivated, and there is no danger of covering the plants no matter how young they may be, since the burden of the earth turned is deposited around the rear portion of the plant While there is a proper amount placed along the front and the sides.

As has heretofore been stated the'point D is preferably made an integral port-ion of the auxiliary mold board, and the pointis provided with an opening to receive a bolt 12; in ap-:

plying the attachment to an ordinary mold boardthe ordinary point is removed and the auxiliary mold board is seated upon the lower portion of the main mold board of the'plow, which remains upon the shank, and the point of the attachment rests upon the toe B of the main or ordinary shank, and the" bolt 12, is passed through the bolt aperture in the toe and through'thc aperture in the point of the attachment. It will thus be observed that an ordinary turning plow may be expeditiously and conveniently converted into a Specific turning plow especially adapted for the cultivation of small plants, and the storage and cost of an extra implement for this purpose are thereby dispensed with, r 7

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. A turning attachment for'ordinary plows, the same consisting of a mold board, shallow as to width and provided with a graduated over-hanging upper edge,vvhich edge is curved upward and outward from the body, the forward end of the overhanging section of the mold board meeting the front edge of its body portion, while the rear section of the overhanging portion is arched over the rear upper edge'of the'body, substantially as shown and the corresponding part of the ordinary mold board, and a point forming'a continuation of the lower end of the auxiliary mold board, substantially as shown and described, as and for the purpose specified.
