structed and combined substantially as and for 

 the purpose herein shown and specified. 



2. The combination with a fixed pair of an- 

 chors, Z Z' of a snatch block carriage engine, 

 and chains connecting the snatch block with 

 the engine, as described, so that after the band 

 which connects the snatch block carriage with 

 anchor Z has been shifted to and coupled with 

 the next anchor Z' the snatch block carriage 

 may be drawn into its operative position in a 

 line with anchor Z' and the engine by the oper- 

 ation of the latter and the chains which connect 

 it with the snatch block substantially as and 

 for the purpose herein shown and set forth.

York, N. Y. Steam Plows. May 16, 1882. 



Filed Dec. 8, 1881. 



Claim. 1. In a steam plow having capacity 

 for moving in both directions without turning 

 around, the arrangement of the revoling plow 

 V and upright shaft v outside of the line of 

 travel of the wheels, as and for the purposes 

 herein specified. 



2. The revolving plow V, mounted on the 

 upright shaft v, in combination with the en- 

 gine-shaft C, with its gear-wheel C 2 , counter- 

 shaft D, with its wheels D' D 2 , wheels E' E 2 , 

 clutch R, and shaft E, with its gear-wheel E*, 

 and the train of connection therefrom to the 

 driving-wheels G, as herein specified. 



3. In a steam-plow, the lifting-cylinder L 

 and piston-rod /, arranged alongside the tele- 

 scopic bearing K, and connected by the arm 

 K', and adapted to serve relatively to each 

 other and to the plow V, and its operating 

 means, as herein specified. 



4. In a steam-plow, the latch O, lever P, and 

 spring Q, in combination with the telescopic 

 bearing K and the connected plow V v, as 

 herein specified. 



5. In a steam-plow, the scrapers W, carried 

 on a rocking-shaft, W, supported and loaded 

 as shown and serving relatively to the wheels B, 

 as herein specified. 



6. In a plowing-machine, the driving-wheels 

 G G, plowing device V, operated outside of 

 the path of the driving-wheels, and the cutter- 

 wheel Z, mounted at one end of the machine, 

 combined and arranged as herein specified.

 RUFF, Philadelphia, Pa., assignor to Eliza 

 M. Woodruff, same place. Steam Plows. 

 Aug. 22, 1882. Filed Jan. 23, 1882. 



Claim. 1. The revolving steering track- 

 drum, in combination with mechanism to rotate 

 it, located within the same and secured to a 

 horizontal circular frame, and a bearing for 

 said circular frame, secured to or forming part 

 of the main frame of the machine, substantially 

 as set forth. 



2. The revolving track-drum P, with rails P', 

 in combination with the rack N', frame K, 

 provided with supporting and guide-wheels J 

 H I, engines O O, working the same shaft and 

 set at right angles to each other, gear N, mesh- 



ing with rack N', and intermediate gears by 

 which the rotation of the engine-shaft rotates 

 said gear N, substantially as described. 



3. The revolving track-drum P, with rails P', 

 and rack N', in combination with the truck 

 carrying flanged guide-wheels H J I, which run 

 upon the rails, and gear-wheel N, which meshes 

 with the rack, the said guide-wheels I I being 

 upon the same axle with gear-wheel N, and the 

 flanges on wheels H and J being on opposite 

 sides to the flanges on wheels I I, substantially 

 as described. 



4. The revolving track-drum P, with rails P', 

 rock N', and truck located within said drum 

 P, in combination with engine, gears, and roof, 

 substantially as described. 



5. In a self-propelling carriage, a front or 

 guiding truck arranged to turn upon a vertical 

 axis, and provided with separate or independ- 

 ent propelling-power, said propelling-power 

 being adapted to actuate said guiding-truck, 

 causing it to rotate upon its horizontal axis and 

 independent of its movement upon its vertical 

 axis, substantially as and for the purpose speci- 

 fied. 



6. In combination with guiding-truck D', 

 the reversible steam-engines, with pinion B 5 , 

 spur-wheels B 6 , coil-drums B 7 , wire rope A 2 , 

 angle-sheaves/ 5 , drum h*, and vertical shaft, 

 with pinion and chain, as set forth. 



7. The lifting steam-cylinder, in combination 

 with the lifting-shaft, independent plows, and 

 lifting-cords connecting each plow to the peri- 

 phery of the shaft or a pulley secured thereon, 

 substantially as set forth. 



8. The draft-bar Y, made in sections, piv- 

 oted together and arranged in a line at right 

 angles to the movement of the machine to 

 which it is secured, in combination with the 

 plows pivoted to said draft-bar, said plows be- 

 ing all arranged abreast and independent of 

 each other, as set forth. 



9. The jointed draft-bar to which the plows 

 are independently hinged, in combination with 

 the plows all arranged abreast, and a lifting- 

 shaft provided with pulleys, to the periphery 

 of which are secured the lifting-cords, there 

 being a separate cord to each plow, and which 

 cord passes over pulleys, as shown, to allow the 

 plow to automatically adjust itself to the ground, 

 as shown and set forth. 



10. The steering or guiding track-drum, in 

 combination with a steam-motor located within 

 said drum, in combination with steam and ex- 

 haust pipes, and a universal or tubular joint in 

 said steam-pipe, and arranged over the pivotal 

 point of said track-drum to allow it to be turned 

 horizontally without injury to the steam-pipes,
