COLTERS. 



13. BANCROFT WOODCOCK. Mount 

 Pleasant, Pa. Plows. June 14, 1838. 



(A.I.) to Patent dated June 14, 1837. 



As described in my patent, the reversing 

 cutter was made flat on the side which fitted 

 into the recess on the land side, made to re- 

 ceive it. I now cast it with three projections 

 a a a on the three cutting edges, rising- in a 

 regular slope from each of the cutting edges 

 and undercut at each of the edges, so as to 

 slip over upon the front edge of the land side 

 and thus to protect it from being worn, and 

 at the same time to hold the reversing cutters 

 in place. Instead of fastening the reversing 

 cutter by a wedge, I now fasten it by means' 

 of a countersunk screw, recesses are cast in 

 the band side to admit two of the projections 

 a a, while the third is in use. 



Claim. The forming of the projections a a a, 

 upon my said reversing cutter, in the man- 

 ner set forth, to slip over upon and protect the 

 three edges of the land side, 



2,529. HOWARD DELANO, Motts- 



ville, N. Y. Colters. Apr. 1, 1842. 



Claim. The combination and employment 

 with a plow of a revolving colter which is ser- 

 rated or furnished with teeth around its peri- 

 phery, so sharpened as to constitute cutting 

 edges, and to operate substantially in the man- 

 ner herein set forth. 



5,526. FREDERICK C. SMITH, Har- 

 pers Ferry, Va. Plow Colters. Apr. 25, 

 1848. 



The nature of my invention consists in the 

 combination of a colter with the share and 

 mold-board in such a manner that the colter, 

 serves not only the purpose of a colter, but 

 also as a cutting-edge at the front of the mold- 

 board and as a supporting-brace for securing 

 the share and mold-board to each other. 



Claim. The combination of the inclined 

 self-clearing colter and point (in one piece 

 with the share and mold-board in such a man- 

 ner that the colter serves not only the pur- 

 pose of a colter, but also as a cutting edge for 

 the mold-board and a supporting brace for 

 giving stiffness and strength to the share and 

 mold-board, substantially as herein set forth, 

 not confining my self to the identical manner 

 of accomplishing this object, as herein set 

 forth, but to some-thing substantially the 

 same. 



7,736. AUSTIN and AUSTIN K. 

 WHETTLESY, Spring Port, N. Y. Fas- 

 tening of Colters to Plows. Oct. 22, 

 1850. 



Claim. The construction of the double 

 plates, held in parallel position by the com- 

 bined action of the colter and the bolts K, K, 

 substantially as described, and for purposes as 

 above set forth. 



12,627. THOS. J. HALL, Tawakana 



Hills, Texas. Plows. Apr. 3, 1855. 



The cutter B swivels in the beam A, and is 

 supported by an arm near its edge so as to fol- 

 low the direction of the point of the beam. 



I do not claim a cutting wheel in connec- 

 tion with a plow, as this has been done re- 

 peatedly. 



Claim. So hanging the cutter to the beam 

 that it may swivel therein, in combination 

 with the supports at the edge of the wheel, sub- 

 stantially as set forth and described.

 ees of Thomas J.- Hall. Plows. Patented

 years; reissued Dec. 28, 1869. 

 Claim 1. The cutter or colter-wheel B, 

 freely revolving on its own axis, when attached 

 to the beam A of a plow, so that it will swivel 

 or turn in such attachment, and the wheel col- 

 ter be free to vibrate laterally, and follow the 

 line of draught or direction given to the beam 

 of the plow, in the manner described. 



2. The combination of the slotted rod b, 

 curved arms c c, and wheel colter B, with the

34,893. JOSIAH LONG, Leavenworth, 



Ind. Cutter Attachments to Plows. Apr. 



8, 1862. 



This invention consists of a curve cutter at- 

 tached to the front part of a mold board, and 

 attached at its extremity tothe beam by a staple. 

 A brace extends back from the cutter, and is 

 attached to the upright shaft of the plow so 

 as to form a substantial support for the whole. 



Claim. The cutter, constructed as de- 

 scribed, attached to the plow, as and for the 

 purposes set forth. 



37,065. W. H. WILLARD, Cleveland- 

 Ohio. Revolving Extension Colters and 

 Gauge Wheels Combined. Dec. 2, 1862, 

 The rim of the gauge wheel, which latter is 

 attached to the plow beam in the ordinary 

 manner,, is made in two parts secured in place 

 by means of nuts and screws. The extension 

 colter consists of four segmental steel plates, 

 in which slots are made so as to allow them to 

 slide upon the connecting bars and extend 

 more or less beyond the face of the wheel, be- 

 tween the rims of which they are clamped. 



Claim. A gauge wheel and revolving ex- 

 tension colter, constructed and operating 

 substantially as and for the purpose specified.
