PLOWS

the screws and bolts passing through the eyes 

 and beam. The durability of the plow so far 

 as the stock, and ribs are concened is greatly 

 increased from the fact that all the wood is 

 above ground and no joints are exposed to re- 

 ceive the water and thereby occasion rot. 



Claim. I. The first and most important is 

 in the use of the ribs in place of the common 

 mold board. 



2. The heel of the plow extending up to the 

 wood. 



3. The plan of stocking the plow. 



NATHAN BAKER, Penn Township, Mich. 



Plows. Mar. 24, 1835. 



No claim. In the triangle No. 1 is a repre- 

 sentation of the curvature of the fore part of 

 the mold-board, and it varies from a straight 

 line nineteen and one-half inches in length, 

 extended from the point of the plowshare to 

 the height of eleven and one-half inches per- 

 pendicular. The first distance, taken at right 

 angles from said line six inches from the point 

 of said share, was found to be two and one- 

 half inches to said mold-board; second dis- 

 tance, taken as aforesaid, ten and one-half 

 inches from said point is two and three-quar- 

 ters inches; third distance, taken as aforesaid, 

 fourteen and one-half inches from said point, 

 is two inches. 



In triangle No. 2 is a representation of the 

 curvature of the aforesaid mold-board, showing 

 its variation from a straight line thirty-eight 

 inches long, extending from the point of the 

 plowshare to the extreme hind part of the mold- 

 board to the height of ten inches perpendicu- 

 lar. The first distance, taken from said line 

 nine inches from the point of said plowshare, 

 and at right angles, is one and three-quarters 

 inch from said line to the mold-board; second 

 distance, fifteen inches from said line, taken as 

 aforesaid, is two inches; third distance, taken 

 as aforesaid, twenty-one inches from said 

 point, two and three-eights inches; fourth dis- 

 tance, taken as aforesaid, twenty-seven inches 

 from said point, two and three-eighths inches; 

 fifth distance, taken as aforesaid, thirty-three 

 inches from said point, one and one-half 

 inch. 



In the tiiansje No. 3 is a representation of 

 the mold-board, showing its variation from a 

 straight line twenty-four inches long, extend- 

 ing from the point of said plowshare, and di- 

 viding the angle formed by the intersection of 

 the other two lines in two equal parts, to the 

 top of the mold-board to the height of eleven 

 inches. The first distance, taken at right 

 angles from said line to the mold-board, nine 

 inches from the point of said share, is three and 

 one-half inches; second distance, taken as 

 aforesaid, fourteen inches from said point, is 

 four inches; third distance, taken as aforesaid, 

 nineteen inches from said point, is three and 

 one-half inches. 



Figure No. 1 is a side view of said plow. A 

 is the beam, six feet long; B, the colter, the 

 point made of steel, and extending six inches 



beyond the point of the plowshare; C, the 

 mold-board, including the front side, which is 

 four inches wide; D*and E, the handles. Fig. 

 No. 1, is a top view of the said plow. A is the 

 mold-board, made of cast iron; C, the plow- 

 share or point, made of steel, twenty-one inches 

 in length and four inches in breadth. 



The said steel-pointed plow will turn a fur- 

 row square over, so as to make a joint with the 

 preceding furrow when propelled by any suffi- 

 cient power. 



WILLIAM M. WALKER,, Washington- 

 ville, Pa. Plows. Oct. 6, 1835. 



Claim. The peculiar formation of the sheath 

 or standard, and the projections on the inner 

 sides of the mold-board which give the sheath 

 or standard a leaning position, and cause the 

 plow to take land as described. 



JOHN DOLHANER, Canton, Ohio. 

 Plows. Jan. 15, 1836. 



No Claim. 1. In the beam, which is described 

 as follows, to wit: length of the beam, (from 

 letter D to letter E in the drawing,) five feet 

 six inches. The part of the drawing marked 

 D C E represents the landside, and not the top 

 of the beam. From letter D to letter C is two 

 feet six inches, and on the landside straight. 

 At letter C it curves to the left toward mold- 

 board side, or, rather, at that point describes 

 an obtuse angle, and thence runs straight to 

 letter E, three feet, and one and three-fourths 

 inch to the left of a straight line continued as 

 between D and C. The foregoing represents 

 a left-hand plow. For a right-hand plow it 

 should be reversed. The effect is that it causes 

 the plow to cut the proper quantity of land, 

 and in a great measure to guide itself. 



2. In the mold-board and landside, which 

 are so constructed that the landside enters a 

 groove in the mold-board at such a distance 

 from the point of the latter as not to weaken 

 it, and is riveted so as to give permanency and 

 strength, whereas, according to the old modes 

 of constructing, the landside is merely lapped 

 on the mold-board for reference. (See draw- 

 ing at letter A.) 



3. In that part of the landside which is fast- 

 ened to the handle. The particular improve- 

 ment consists in this, that the upper part of 

 the back end projects backward in such a man- 

 ner as to strengthen the handle by covering it. 

 (See drawing at letter B.) 



DAVID PROUTY AND JOHN MEARS, 



Dorchester, Mass. Plows. Mar. 4, 1836. 



Claim. 1. The inclining the standard and 

 landslide so as to form an acute angle with the 

 plane of the share. 



2. The placing the beam on a parallel to 

 the landside within the body of the plow, and 

 its center nearly in the perpendicular of the 

 center of resistance. 



3. The forming the top of the standard for 

 brace and draft.
