POINTS 





CONELIUS BERGEN, Brooklyn, N. Y. 



Plow-Points. Nov. n, 1819. 



No claim. A removable and reversable point 

 and share, separately attached. The point has 

 a longitudinal groove in either side, into which 

 the edge of the share takes for steadying it. 

 The share is provided with a shoulder which 

 abuts the mold-board to which it is recured. 



ROSS WINANS, Vernon, N. Y. Plows. 



May 11, 1824. 



No claim. A rhombid shaped point made of 

 wrought or cast iron or steel is secured to the 

 upper side of the lower edge of the mold-board 

 and is capable of being adjusted up or down 

 and reversed to bring the different wearing sur- 

 faces into position. 



WILLIAM BEACH, Philadelphia, Pa. 



Plow-Points. Nov. 8, 1825. 



No claim. A detachable three winged con- 

 caved and self-sharpening tooth or point ; a 

 three winged point or share for a two winged 

 plow of triangular shape. The tooth or point 

 and share may be all" cast in one piece (or not) 

 with the wings extending out from the center 

 in a triangular form. 



JAMES H. CONKLIN, Peekskill, N. Y. 



Plows. Jan. 13, 1830. 



Claim. 1. The improvement in the cast- 

 iron plow share, as described, the share having 

 two points and two eyes which may be reversed 

 at pleasure, thereby serving the purpose of 

 two common shares and costing no more than 

 one of the ordinary kind. 



2. The mode of fastening the share to the 

 mold-board as described.

The share which I use is the same in its gen- 

 eral form as that described in patent to me 

 Nov., 23, 1836. The face on each side has its 

 surface flat from each cutting-edge to a shoulder. 

 By this means I am enabled to make the share so 

 thin throughout its width that as it wears up 

 toward the mold-board it is still sufficiently so 

 on its edge to pass freely through the ground. 

 It has two holes through it, by one or the other 

 of which it is bolted to the mold-board. 



In the landside of my plow, within a recess 

 or depcession I place a reversing "cutter, the 

 general form of which is that of a triangle, 

 either end of which may be turned forward, so 

 as to constitute the cutting-edge formed by the 

 junction of the mold-board and landside of the 

 plow. This reversing cutter may be fastened 

 in its place by making it hollow, so as to re- 

 ceive a part of the landside, allowing space 

 enough between the piece and the cutter to in- 



sert a wedge or wedges. The edges are made 

 dovetailing or beveled, to clip in the inner 

 edges and hold it firmly against the landside 

 when wedged. One of the edges may reach to 

 the bottom of the landside ; or it may stand a 

 little above it, having a strip of iron below it, 

 which strip in this case forms a side of the 

 recess. 



I have also made an improvement in the 

 manner of making the renewable point. I now 

 prepare a V-formed piece of iron or steel, which 

 fits onto the shank embracing it on both sides, 

 and fastened to it by a rivet passing through 

 the whole. The renewable point is thus rend- 

 ered more permanent than upon the former 

 plan, and the shank is prefectly protected from 

 grinding out in wear. 



In order to secure the landside to the mold- 

 board, I cast the fitting part with dovetail junc- 

 tures in such a way as that, when secured to- 

 gether by wedges passed between cheeks adapt- 

 ed to that purpose, the parts interlock, and 

 retained firmly in their places. 



Claim. 1. Making it with plain surfaces in- 

 stead of curved ones, in the manner described, 

 continuing such surfaces to the shoulder on 

 each side, so as to leave the metal throughout 

 so thin that when it wears off by use the share 

 will still present a thin edge to the grouud. 



2. The reversing cutter, received into a re- 

 cess or the landside and capable of having 

 either of its edges presented forward, so as to 

 form the cutting-edge of the plow, and secured 

 in its place on the landside by a wedge or 

 wedges, or in any other manner which may be 

 preferred. 



3. The mode of forming the renewable point, 

 as herein specifically set forth. 



476. B. WOODCOCK, Mount Pleasant, 

 Pa. Plows. Patent 233 dated June 14, 

 1837. Reissued Nov. 23, 1837. 

 Claim. 1. The making it with plain sur- 

 faces, instead of curved ones, in the manner 

 described, containing such surfaces' shoulder 

 on each side, so as to leave the metal through- 

 out so thin that when it wears off by use the 

 share will still present a thin edge to the ground. 



2. The reversing-cutter, received into a re- 

 cess on the landside and capable of having 

 either of its edges presented forward so as to 

 form the cutting-edge of the plow, and secur- 

 ed in its place on the hndside by a wedge or 

 wedges, or in any other manner which may be 

 preferred. 



3. The mode of forming the renewable point, 

 as herein specially set forth, and the dovetailed 

 or acute angular form given to the shank of the 

 renewable point for the purpose of clasping 

 and holding down the reversible cutter.
