Awhereby the 5tov provide ineans plowin-ay be"A caused to 'run evenly and' W ereby'the plowshare; may be A further object-:is

caused to run at a greater-,or less depth. j

With the foregoing and, other objects in I view, that'will readil appear; as .the nature-4 of theinventionisf etter understood,- the vinvention'.-'consists in the novel features ofY construction, combination and arrangementv of parts illustrated in 'the drawings' and particularly pointed out .in thefa-ppended.

In the accom 'anzing drawings: Figure 1 is a view in si e :e evation of a. plow .proa vided with my improvements.V Fig. 2 isa cross-section out on the line 2--2 'of Figl 1 and Fig. 3 is a detail perspective view-ofthe adjustable-sole piece. i f I l In theembodiment illustrated, 'the' nu-j mera] 1, indicates the plow whichV comprises the usual mold board plowshareandland 40 I' side, 42, 3 and 4,' respectively.

Said plate is of the same thickness vas the la'ndslde and when vfirst ap l-iedin position itslower edge is flush with t e llower edgeof the vertical portion, 6, of the plowshare.' Said sole plate is provided at its inner side edge with two longitudinally spaced vertically slotted upright extensions, 7, the purpose of which will be shown. A rectangular late, 8, is arranged on the inner face of the andside and i's rovided with two inwardly' extending latera ly projecting threaded studs or extensions, 9, adapted to be received by the slots of the slotted extensions of the -sole plates.

L; The frontv or 'forward end of the plate 8 1s preferably formed withan obliquely disposed bearing portion 1 1, which fits under the mold board and plowA f share and is riveted or otherwise secured -in .such position;

By this construction not only may the plate be securely. fastened in osition, but a secure. and'ilm jointformed'tor the meeting edges of the Amold-'bolard an'd'plow share.

From thegffegoing-- description taken' in connection -with the'drawin'gs itis thought thatthe construction-*and operation ofthe -invention'will be understoodwithout requiring` a;more extended explanation. l

Having thus described my'invention, what vI claim `as new and desire tol secure. by Letters-Patent is:v 'A plow of the character specified, embrace ing` a longitudinally disposedsu porting platejarran ed on the inner face of t e landside, said p ate being' formed at its forward -end with an obliquely disposed v rearwardly .extending enlarged portion', designed 'to fit under the meeting edges of the mold board and plow share, said enlarged portion providing a support and joint for such meeting Vedges and part' of the fastening .means for the sup orting plate, a sole under t e landside, means tor connectlng the vsole plate with the supporting plate, said means comprising longitudinally spaced threaded members extendinglaterally from the inner face offthe supporting plate, lon itudinallyslotted extensions formed on t e inner side edgeapf the sole plate to receiveV PATRICK DEEVY.'
