PLOWS. 



mold, behind a small shoulder, on said mold 

 within half an inch of its point, and made fast 

 to the share by a hook welded on its inside the 

 upper end of which penetrates the beam and is 

 made fast by a screw on top. There is, further 

 more an iron bolt passing through the beam 

 and sheath, bracing the whole together. 



The beam handles and sheath of said plow 

 are constructed similar to those of other plows 

 now in use the improvement here claimed, as 

 aforesaid, differing from other plows now in 

 use particularly in the cutter, which is en- 

 tirely new, the mold differing also from other 

 plows now in use by having the screw behind 

 and in the sheath, before described differing 

 also in the manner in which it receives the 

 cutter. The shape of the mold also differs 

 from others in use, but which difference is in- 

 describable.

Claim. The front curved edge of the mold 

 board or standard, between the upper part of 

 the share and the beam, the object of which is 

 to make the plow clear itself. 



SAMUEL NISBET, Toboyne Township, 



Pa. Plows. May 25, 1830. 



No Claim. This plow consists of the fol- 

 ing principal parts viz : first the mold board 

 and sheath ; second, the wrought iron share ; 

 third, the colter; fourth, the beam and 

 handles. 



First. The mold board and sheath are 

 made cast iron and cast together solid. There 

 is a tenon in the lower part of the sheath, that 

 sets into the socket of the share. The sheath or 

 mold board extends up through the beam, and 

 has two projections cast on it, one on each 

 side, on which the beam rests. A bar extend- 

 from the sheath on the land side to the molds 

 board on the inner side, which acts as a stay 

 and support to both the sheath and mold- 

 board, and is cast solid with them. 



Second. The shares is made ofwrought- 

 iron, and is of the common form and size. 



Third. The colter is made of wrought iron 

 and of the common shape and size. 



Fourth. The beam and handles are made of 

 wood and of the common shape and size. 



Claim. The construction of the mold board 

 and sheath, as before described. 



SAMSON FELTON, Huntingdon, Pa. 



Plows. Nov. 1, 1830. 



Claim. The manner of making the share 

 and mold board, as before described, the plate 

 or floor which connects them together, the 

 cross-bar, the saddle or seat on which the 

 beam rests, also the bolt passing through the 

 beam and connected with the cross-bar of the 

 share, and landside having a thumbscrew on 

 top for regulating it.

 Ky. Plows. Jan. 12, 1831. 



No claim. All parts pressed by or coming in 

 contact with the earth are of metallic substance, 

 the bar-share and point of wrought iron and 

 steel, the mold or rolling board of cast iron. The 

 bar and share are welded together, forming 

 one piece. (See Plate A.) The bar is sloped 

 projectively from its center to the front point. 

 (See Plate B, Figures 1 and 2.) The share is 

 of a solid triangular shape, forming a level 

 base on top to the width of the rolling-board 

 P A F 1 23, thence sloped down at near right 

 angles, so as to form a smooth and regular cir- 

 cle with the face of the rolling-board from one 

 point to the other, and upon the entire face of 

 the plow P B F 3 4 5, the front edge of the 

 rolling-board serving as a colter, being cast 

 solid in front, with a sharp edge extending up 

 near the under part of the beam, forming a 

 quarter-circle, P B F 6 7, having two wrought 

 screws cast in said board, the one in its heel, 

 the other in the rear side of the solid part P 

 A F 4 10, through which part is also cast a 

 tube-hole, terminating two-thirds width in the 

 rear of said board P A F 5 and B F 14. 



The stock (consisting of a wooden beam, a 

 sheath, helve, two handles and three rounds) is 

 united to the rolling-board permanently, with 

 the wrought screw in its rear, which passes 

 through the sheath or helve and screwed firm; 

 P B F 8, an iron rod passing through (from 

 the under part of the share) the tube-hole in 

 the rolling-board, through the beam, and 

 screwed by a tap on top; P A F 6 and PBF 

 9 10, an iron bolt passing through the face of 

 the board and sheath and riveted. The han- 

 dles are put on with iron pins, screws and taps; 

 P A F 7 8 9, a lock rod or brace extending 

 through the sheath to the under part of the 

 beam, along the same near the end, where it is 

 attached to the clevis by a screw-driver which 

 passes through the beam and clevis; P B F 1 1 

 12, an iron bolt passing through said rod or 

 brace, the beam, and screwed at top P B F 13. 

 The stock and rolling-board thus united is 

 designed not to be separated, and when placed 

 upon the bar and share the whole is perma- 

 nently bound together by the screw in the heel 

 of the board, a screw-pin in the front point 

 thereof, P A F 10 11, both of which pass 

 through the level base of the share and screwed 

 by taps underneath, as also by the iron rod 

 which passes through the share, the tube-hole 

 in the board, and through the beam, with a 

 screw and tap on the top; P B F q 10. the
