76 Report on Trials of Plows. 



to give additional strength to the land side sidewise, and to con- 

 nect it at a proper angle with the mould-board, I make a rib, //, 

 Fig. 3, on the land side, about midway between the top and bot- 

 tom, say about two and a half inches from the bottom. This rib 

 is made broad where it joins the mould-board at /, and tapers as 

 it goes back to the birth for the handle to fasten on, where it ter- 

 minates at i, Fig. 3, where I make a projection or jog, which 

 cannot be represented in the drawing, to raise about half an inch 

 for the end of the handle to rest against. This rest, or jog, sus- 

 tains the pressure of the handle endwise, so that the screw bolt 

 is only required to confine it to the side. C. Newbold made the 

 standard of his plow to pass up through a mortise in the beam; 

 mine extends only up to the beam; the beam is fastened on it 

 with a strong iron scrcAV bolt, which may be made either to pass 

 up through the top of the standard in the front part of it and 

 through the beam vertically, j, Fig. 5, or to pass through the beam 

 in an inclined direction, and containing the same inclination 

 through the top of the standard, having on the inside a birth for 

 the nut to work on, J, Fig. 4. There are plows in which the 

 beam is fastened on the top of the standard with two bolts. The 

 improvement which I claim to have invented consists, therefore, 

 only in these particular modes of connection. The advantage of 

 it consists in this — that the fastenings being made by a single 

 bolt upon which the beam can turn, it enables me to adjust the 

 landing of the plow by a simple operation in altering the position 

 of the end of the beam, where it is united to the handle. This 

 will be more particularly described when I speak of the stocking 

 of the plow. 



"There have been, also, land sides heretofore constructed which 

 were made thin and broad, but supported in a difterent manner. 

 My improvement, therefore, consists only in the mode of making 

 the rib, the projection or jog in the inside of the land side, the 

 form of the top of the standard or the fore and top part of the 

 mould-board, which, being made to extend forward under the 

 beam, equalizes the bearing of the beam. Thus a smaller piece 

 of wood will be more sufiicient to form a beam than if the fasten- 

 ings to the handle and standard are brought nearer to each other. 



" Fourth — The shoe: Charles Newbold made a bar of wrought 

 iron which he caused to extend back from the share to the end of 

 the land side, below it, and fastened to it with a sci'cw bolt pass- 

 ing lip through the shoe and land si(l(>.
