217,506. BENJAMIN S. BENSON, 



Baltimore, Md. Traction - Engines and 



Steam Plows. July 15, 1879. Filed Nov. 



19, 1878. 



Claim. 1. A gang of plows attached to and 

 combined with a continuous flexible spring-bar, 

 forming the main cross-bar of the frame, to 

 adapt the plows to the unevenness of the ground, 

 as described. 



2. The combination, with the plow-frame 

 and the plow pivoted thereto, of a steam -cyl- 

 inder and piston, arranged substantially as des- 

 cribed, to apply an elastic steam -pressure to 

 said plow, as set forth. 



3. The plow having a bend in its beam at b 

 and pivoted at this point to its frame, in com- 

 bination with the steam-cylinder and piston 

 swung upon trunnions, as described. 



4. The gang-frame composed of parallel bars 

 bifurcated at their front ends and provided with 

 horizontal friction-rollers, in combination with 

 the traction device and a transverse rod at- 

 tached to said traction device and extending 

 through the forked ends of the parallel bars in 

 the rear of the friction-wheels, as shown and 

 described. 



5. The flexible spring-bar and adjustable 

 gauge-wheels, in combination with the plows, 

 as described. 



6. The combination, with the plows, of the 

 gang-frame, consisting of the parallel bars E, 

 right-angular bar E 1 , and oblique flexible spring- 

 bar E 2 , substantially as described. 



7. The combination, with a gang of plows, 

 of a wheel, K, located upon the mold -board 

 side of the gang, and constructed with a flange, 

 a 1 , and a convex face adjacent to said gang, 

 adapted to bind against the vertical wall of 

 earth of the preceding furrow and counteract 

 the lateral thrust of the gang, as described. 



8. The endless traction-chains consisting of 

 the axial rods a , the triangular links c' , having 

 their apices pointing outwardly from the center, 

 and provided with loosely-connected feet or 

 shoes d' , all combined as shown and described. 



9. The combination, with the traction-chain, 

 constructed substantially as described, and 

 having fricting-rollers b' , of a flexible spring- 

 rail, O, attached to the frame-work of the ma- 

 chine and adapted to bear and run upon the 



friction-rollers of the chain as the latter is laid 

 down in front, as specified. 



10. The wheels N N', constructed with gear- 

 teeth upon their peripheries and projecting 

 notched flanges upon each side, in combination 

 with the driving-pinions M M' and the traction- 

 chain jointed by axial rods a', as described. 



11. The combination, with an endless trac- 

 tion-chain, of one or more steam-cylinders and 

 pistons for applying an elastic steam-pressure 

 to give greater traction to the chain or allow it 

 to yield, as set forth. 



12. The combination, with the endless trac- 

 tion-chain, of the rails Of, the yoke-shiped 

 frames P, the cross-heads Q, connecting said 

 yokes, and the steam-piston rods connected to 

 said cross-heads, substantially as shown and 

 described. 



13. The combination, with the endless trac- 

 tion-chain and the steam-cylinders located 

 within said chains, of the valve-box T, the 

 communicating pipes, and operating-levers, sub- 

 stantially as and for the purpose described. 



14. The combination of an endless traction- 

 chain having friction-rollers, a flexible spring- 

 rail resting upon said friction-rollers, and a 

 steam-piston connected to said flexible rail and 

 adapted to apply pressure to the chain, substan- 

 tially as described. 



220,365. WILLIAM H. FOYE, San 



Francisco, Cal. Steam Farming Apparatus. 



Oct. 7, 1879. Filed May 13, 1879. 



Claim. 1. The steam farming apparatus, 

 substantially as described, consisting of the 

 platform A, supported on the bent rear axle 

 and upon the front guiding-wheels, which are 

 carried in the rim above the platform, in com- 

 bination with the boiler and engine, arranged 

 on the front of the platform, and with detach- 

 able mechanism in rear of the boiler on said 

 platform, as set forth. 



2. The combination, with the platform A, 

 supported and steered as described, and carry- 

 ing boiler and engine, of the secondary detach- 

 able platform W, carrying the shaft, clutches, 

 and drum or drums, the said parts being ar- 

 ranged to be driven by the engine, as set forth. 



3. The horizontal gear-wheel and drum Q, 

 with its driving-pinion O and the rope V, in 

 combination with the gear-wheel and drum R, 

 with its driving-pinion P and rope U, whereby 

 the plows may be hauled across the field and 

 the engine advanced, substantially as herein 

 described. 



4. The shaft N, with its pinions O P, mov- 

 ing upon feathers, and controlled by the levers 

 S and T, in combination with the gear-wheels 

 and drums Q R, mounted one above the other 

 upon the same vertical shaft, whereby the drums 

 with their respective ropes U and V may be 

 actuated independently of each other, substan- 

 tially as and for the purpose herein described. 



5. The gear-wheels Q and R, with their rope- 

 winding drums, working independently upon 

 the same vertical shaft, the pinions O and P, 

 levers S and T, driving-shaft N, and pinion M,
