 movement substantially as described. 



4. 'I he combination with an endless chain 

 carrying plows upon it around and over guide-

Claim. 1. In a plow, the combination, with 

 a beam mounted on suitable runners, of a right 

 and left hand plow placed back to back and 

 connected together by suitable braces, a land- 

 side or stock for the double plow, by which it 

 is adjusted vertically, and a vertically-adjust- 

 able sole placed on a level with the bottom of 

 the plow and extending between the outer ends 

 of the points, substantially as set forth. 



2. In a plow, the combination, with a beam 

 curved at both ends and mounted on suitable 

 runners, a landside or stock, right and left hand 

 plows and sole, of inclined cutters placed on a 

 line with the landside or stock at both ends 

 thereof, and adapted to protect the projecting 

 end of the landside and point, substantially as 

 set forth. 



3. In a plow, the combination, with a beam 

 mounted on pivoted runners, the side beam and 

 runners adapted to move on the surface of the 



ground, of a right and left hand plow adjusta- 

 bly secured to the beam by a single landside or 

 stock, and adjustable cutters secured to said 

 beam at both extremities of the landside, sub- 

 stantially as set forth. 



4. The combination, with a beam mounted 

 on runners and carrying a right and left plow, 

 of cords or chains connecting the said runners, 

 and a chain connecting one set of runners with 

 a winding-drum rigidly secured on the steering- 

 wheel shaft, substantially as set forth. 



5. In a plow, the combination, with a beam 

 having a right and left hand plow adjustably 

 secured thereto, of runners pivoted to said beam, 

 having metallic flanges adapted to penetrate

Baltimore, Md. Steam Plows. Dec. 27, 



1881. Filed Oct. 21, 1881. 



Claim. 1. The combination, with a trac- 

 tion-chain having presser-feet for contact with 

 the earth, of three sprocket-wheels arranged in 

 triangular relation to each other, and mech- 

 anism for driving the traction-chain, connected 

 directly with the upper-sprocket-wheel to secure 

 a better draft and the better picking up the 

 track, as described. 



2. The combination, with the two systems 

 of traction-chains having presser feet for con- 

 tact with the earth and the triangularly-arranged 

 sprocket-wheels, of a shaft, F, connecting the 

 end sprocket-wheels and having free lateral 

 movement, as described. 



3. The combination, with the two systems 

 of traction-chains and the sprocket-wheels car- 

 rying the same, of the sectional shafts F F, 

 connecting the end sprocket-wheels, and hav- 

 ing a swiveling connection, a, as and for the 

 purpose described. 



4. A traction-chain composed of links made 

 in the form of right-angled triangles, with a 

 rail or way formed on one side of the right an- 

 gles, and with a presser- foot arranged at one 

 end of said link and below the joints of the 

 chain, for the purpose described. 



5. The combination of a traction-chain hav- 

 ing rails or ways on the upper surface of its 

 links, a set of stationary trucks resting on said 

 rails, and a set of spring-seated presser-feet 

 connected to and supporting the traction-chain, 

 substantially as described. 



6. A traction-chain composed of hinge-rods 

 and jointed links, having rails or ways on one 

 side and presser-feet on the other, and having 

 at their opposite ends tongues and forks, with 

 elongated slots in the tongues, through which 

 the hinge-rods pass to render the chain flexible 

 in lateral direction, as described. 



7. The combination of a set of stationary 

 trucks and a traction-chain composed of links 

 having presser-feet on one side and rails or ways 

 on the opposite side, shouldered or rabbeted so 

 as to form lap-joints, as described.
