PLOWS

with the jog or rest on the landside to sustain 

 the handle, and the extension of the standard 

 or fore and top part of the mold-board for- 

 ward so much further under the beam than is 

 usual, all of which I believe tend much to the im- 

 provement of the plow, and which I claim the 

 use and control of, as aforesaid. 



3. My mode of making and manner of ap- 

 plying and using the share "of the plow, as here 

 described, whether made of wrought or cast 

 iron. 



4. Believing that the shapes for the throat or 

 fore part and hind part of the mold-board 

 have not been known or used before I applied 

 them to use, and that they are valuable im- 

 provements in the construction and use of the 

 plow; claim the whole and exclusive right of 

 the use and control of them to use and vend to 

 others, &c. 



5. Constructing the shoe so that it will pro- 

 tect both the side and the bottom of the land- 

 side, and my mode of making the cast-iron 

 shoe in metallic molds. 



6. My mode of applying the beam to the 

 standard, and my manner of raising and low- 

 ering it on the standard, and my mode of fast- 

 ening the end of the beam on the side of the 

 handle, together with that of adjusting the fore 

 end of the beam by turning it to the right or 

 left, and of making the hind end of it fast to 

 the handle higher or lower, and the applica- 

 tion of the blocks between the beam and the 

 standard, and the beam and the handle. 



7. The mode of applying the colter to the 

 side of the beam instead of through a mortise 

 in it, and more especially that of the particu- 

 lar manner of fastening the sward-colter to the 

 plow and using it so as not to cut the sod un- 

 til the point of the share has raised it up so as 

 to have it on a strain.

 plow up to the point of the mold-board, and 

 the application of the improvement in the shoe 

 to raise and lower behind at pleasure. 



2. The method in which the mold-board is 

 wrought, the shape of its face or mold part, 

 the curve or projection over toward the land- 

 side, the long hole through its top for the 

 beam-bolt, the catch at the bottom to fasten it 

 to the share, and the concave groove for the 

 handle. 



3. The structure of the fore part of the 

 mold-board for the cast share and the self- 

 sharpening point, the portion of the brace-bar 

 between the landside and the mold-board for 

 the point to rest on and to fasten to, the 

 length of the point and the manner in which 

 it is fastened to the brace-bar, and the shape 

 of the share for the point to rest upon. 



4. The shape of the sword with two edges, 

 and the manner in which it is fastened to the 

 side of the beam with a staple. 



5. The stock, the method of fastening the

No Claim. The mold being of cast iron, 

 with a square shoulder to rest on the sheath, 

 with two square countersunk holes, through 

 which screws are placed, the one fastening the 

 mold to the sheath and the other fastening the 

 share to the mold. On the hinder part of said 

 mold, there is a limb projecting from the in- 

 side, through which a screw also passes to the 

 share, making fast the hinder part of said mold 

 to the hinder part of said share. There are 

 also two holes through the mold, through 

 which rivets are placed fastening said mold to 

 the sheath. There also two other holes through 

 which rivets are placed fastening said mold to 

 the right hand handle of said plow. 



The share is made of wrought iron a wrought 

 landside with steel on the heel and edge and 

 also a steel point extending back, covering the 

 point of the mold to prevent roots, &c, from 

 lodging under said mold. There are also two 

 holes in the share, one before and the other 

 back, to receive the screws from the mold 

 aforesaid. 



The cutter of said plow is made of wrought 

 iron, with a steel edge, setting closely to the
