' vented a new and useful Reversible Plow, of

which the following is a specification.

My invention relates to improvements in reversible plows in which the cutting appa ratus is reversible, so as to throw its furrowslice to the right or the left, as maybe desired, and at the same time it furnishes a shovel-plow for tending crops planted in hills or rows. I attain these objects by the mechanism illus trated in the accompanying drawings, in which- Figure l is a perspective view of my im-' proved plow. Fig. 2 is a plan view. Fig. ,3 is a perspective view of a modification. Fig. 4 is a detail.-

$imilar letters refer to similar parts throughoutthe several views.

The plow-beam A, plow-foot B, plow -tail (1, with braces Z and upright c, constitute the frame-work of the plow. To the under surface of plow-foot B there is fastened, by means of screws or otherwise, a strip of iron of suitable thickness, which comes up within an inch and a half to the front end of B, which strip may be used, or not, at pleasure, the purpose of the same being to make the plow run with greater ease in hardened soil. Plow-beam A has a perforation, through which upright D freely passes. D is pivoted in perforation at of plow-foot B. To upright Dthere is fastened, by means of screws or otherwise, the plowshare E. h

Above plow-beam A one end of arm 6 is firmly fastened to D. The other end, by means of an elbow-joint, is fastened to rod f. Rod f is at g fastened to lever F, is at one end, by means of pin 11, loosely joined to plow-beam A,

passes from there upward, and slides to and fro in a groove formed for that purpose by means of strips 1i and v3, and fastened in any simple way by means of an upright to plowbeam A and plow-tail a. Lever F has on one side lug 7c and on the other spring Z.

Strip 2" is provided with slots m, m, and m, for the purpose of receiving lug 7;. Spring Z furnishes sufficient pressure to keep lug it from slipping out of the slots. On the opposite side from where rod f is fastened to lever F rod 11: is fastened to the same, which rod has its other end fastened to one extremity of arni 0, forming an elbow-joint, by means of pin and perforation. securely fastened to upright 11, which upright passes freely through a hole in plow-beam A and is pivoted at q in plow-foot B. Upright 1), about midway between the plow-beam A, and plow-foot B, has arm 1', which, at its outer end, has pin a. Pin passes freely through perforations in shafts t and 1., of which shaft t is fastened by means of binge r to mold-board G. and shaft by means of hinge a) to moldboa-rd G. Each of the shafts t and t has sev eral perforations, so as to make the range of the mold-boards larger and smaller. For the same purpose are more than one perforation to be formed in arm 0. Mold-board G is also hinged at y and to plow-share E, and mold-board G is hinged at z and z to plowshare E.

Draft-rod uis a device pivoted to the un der side of plow-beam A, by means of which the depth of the plowing is regulated. In case the plow is to be put on wheels, the draftrod u is raised to theplow-beam and the plowtrace is fastened to hook r.

In order to change the reversible plow into a shovel-pl ow, plowshare E and mold-boards G and G are separated from their framework, and in their stead shovel H, and moldboards K and K are fastened to theframe-work of the plow by means of pin win plow-beam, pin w in plow-foot, and shafts t it upon pin 8. The operation of my reversible plow is'as follows: When the lug 7.: on lever F is in slot at, the furrow-slice is thrown to the right. In order to change this to the left, lever F is pressed forward to slot m, thereby, by means of rod f, arm e, and upright D, plowshare E is reversed, and at the same instant, by means of rod to, arm 0, upright 1), arm r, pin 8, and shaft-s t and t, the mold-board G is drawn in and mold-board G is thrown out, so as to make the furrow-slice to fall to the left.

Arm 0 is in its other extremity The reversible plow is changed into ashovelplow by the means explained above. The

boa-rds K and K, by means of the perforations wees? in shafts t and t, can beset Wider and narrower the arm a", the upright 1), arm 0, rod- 20, and lerelatively to each other.
