PLOWS 



NATHAN LOCKLIN, Sparta, N. Y. 



Plows. Apr. 28, 1836. 



Claim. 1. The peculiar formation of the 

 mold-board, landside and share, as described. 



2. The drag at the rear end of the mold- 

 board. 



JACOB PLANK, Carlisle, Pa., Plows, 



June 2, 1836. 



Claim. In the wing of the model-board and 

 brace, the wing of the side piece and joint in 

 which the side piece fits and the branched iron 

 brace as specified. 



JOSHUA GIBBS, Canton, Ohio. Plows. 



June 16, 1836. 



No claim. In the mold -board which has on 

 the front part at letter B in Drawings Nos. 1 

 and 2, a slip-mortise to receive a tenon on the 

 landside, as hereinafter described. 



In the landside, which has on the front end, 

 at letters A in Drawings Nos. 1 and 3, an offset 

 towards the mold-board, or a tenon which laps 

 into and closely fills the slip mortise in the 

 mold-board, leaving the outer surface smooth. 

 The benefits of these are that the two pieces are 

 fastened firmly together, and firmness and so- 

 lidity are thereby given to the plow. 



. In the bottom of the model-board, as repre- 

 sented in Drawing No. 4, letters C and D, 

 which drawing represents the bottom of the 

 model-board. The dotted line in said drawing 

 running at right angles from the landside (rep- 

 resented by letter C) is the rear of the bottom 

 of the mold-board according to the present 

 mode of constructing them. The black line in 

 the rear of this dotted line (at letter D) is the 

 rear termination in my improvement. It pro- 

 jects three-fourths of an inch back of the dotted 

 line and rests against the main post. This for- 

 mation of the mold-board also gives greater 

 strength to the plow. 



In the long screw running up through the 

 share, the mold-board, and the beam, com- 

 monly called the " false colter." Instead of 

 being straight, according to the old mode, it is 

 one-third larger in diameter at the lower end, 

 where it passes through the share, than at the 

 upper part. After it has passed up through the 

 mold-board, the head of the false colter de- 

 scribes but half a circle, leaving one side of it 

 smooth, in order that it may pass through the 

 share close to the bar of the share. This plan 

 leaves the false colter strong at the lower part, 

 where the strain comes, and smaller at the up- 

 per part, where it passes through the beam, so 

 as not to weaken the beam. 



TIMOTHY MILLER, Pittsburg, Pa. 



Plows. July 2, 1836. 



Claim. The convex curvature on the out- 

 side of the landside ; also the bar on the inside 

 of the landside ; also the groove in the mold- 

 board ; also the countersunk hole in the model- 

 board ; also the bars on the shares and projec- 

 tions ; also the rib or bar cast to the back of 

 the model- board. 



259. SAMUEL HARTPENCE and J. 

 D. BOWNE, Kingwood, N. J. Plows. 



Ju!y 5> l8 37- 



Claim. 1. The manner of constructing the 

 cutter with a screw-bolt above, passing through 

 the beam, and a holdfast or clip below, passing 

 through the piece forming the share and point, 

 made in the manner set forth, and holding the 

 whole together, substantially as described. 



2. The placing of a roller upon the rounded 

 part above the cutter, as herein shown, for the 

 purpose of preventing the clogging of the plow. 



260. JOHN C SMITH, Kingwood, N. 

 J. Plows. July 11, 1837. 



Claim. Making the share of the rhomboidal 

 figure beveled and brought to a cutting-edge on 

 two of its ends, so that as one edge wears away 

 it can be reversed or turned end for end, being 

 secured to the sheath by two screws near the 

 center. 



273. J. B. NORTON, Philadelphia, Pa. 



Plows. July 17, 1837. 



Claim. 1. The graduator as respects its 

 principle. 



2. The manner of strengthening and secur- 

 ing the share to the mold-board. 



3. The projection or bulb on the inner part 

 of the landside of the plow, against which the 

 plow-handle rests. 



4. The method of securing the mold-board 

 to the beam by the staple, in the manner before 

 described. 



327. JOHN DEATS, Rocksburg, N. J. 



Plows. July 31, 1837. 



Claim. 1. The manner of forming the pat- 

 tern of the mold-board so as to cast it to de- 

 liver from a single flask, with a tenon or pin 

 cast near its front edge, in the manner and for 

 the purpose described. 



2. The manner of constructing and using the 

 casting which I have denominated the "inner' 7 

 or " false" landside, for attaching and con- 

 necting the various parts which are appended 

 to it. 



3. The particular manner of forming the re- 

 versible plate of cast-iron constituting the back 

 end of the landside. 



4. The placing the beam of the plow in the 

 manner set forth. 



501. STEPHEN McCORMIOK, Auburn, 



Va. Plows. Dec. 1, 1837. 



Claim. 1. The curved form given to the 

 heel of the landside, and also the concave form 

 of its back edge as it rises from the heel to the 

 beam, as herein set forth. 



2. The manner of stocking the plow, so far 

 as the fixing of the handles is concerned, by 

 causing their inner ends to meets about mid- 

 way between the bottom of the landside and 

 the beam, and confining them there in the way 

 described. 



3. The cast-iron clevis, formed and attached 

 to the beam, substantially as herein set forth ; 

 that is to say, embracing the beam bv its con-
