Claim. 1. In a steam plow, the valve of the 

 secondary or plow lifting engine in combination 

 with the propelling engine and mechanism for 

 connecting the two, whereby the plows are 

 raised and lowered automatically, substantially 

 as described. 



2. The combination, substantially as herein 

 described of the pitmen e e' with the plows or 

 slides B B carrying the latter, said pitmen being 

 connected with the plow-slides in front of the 

 plows, for the purposes specified. 



3. The slides B B, provided with three or 

 more rollers b b on either side, in combination 

 with the plows carried by said slides, and the 

 plow frames C C constructed to form straight 

 guides with rising ends c c substantially as 

 herein described. 



4. The combination of the reversely arranged 

 toothed sectors J J, the crank n, the racks K 

 K and the plow frames C C, substantially as 

 specified. 



5. The independent forward section F' of 

 the main faame, hung to rock on the main axle

Two engines or cylinders, distinct in their 

 action and speed, one, to drive the plow, the 

 other to propel the carriage. A horizontally- 

 rotating plow elevated, or its depth governed 

 through a steam pipe and piston rod attached 

 to the vertical plow shaft. 



Claim. 1. The rotating plow V having the 

 inclined plates V 1 and teeth V 2 combined and 

 adapted to serve as and for the purposes herein 

 specified. 



2. In a steam plow the independent steam- 

 cylinders B P, with their respective trains of 

 mechanism combined and adapted, the one to 

 impel the revolving plow and the other the pro- 

 pelling wheels with variable ratios of power 

 and velocity as specified. 



3. In combination with the plow shaft T and 

 its propelling mechanism the connected piston 

 and cylinder A 7 with the controlling valve J, 

 to allow the plows to be raised and lowered at 

 will in the manner herein set forth.

The plows are of auger form, placed upon 

 rotating shafts projecting toward the line of 

 draft and operated by gear and bevel wheels. 

 To the bearing axle a skeleton frame is pivoted 

 secured by a king bolt to the axle of steering- 

 wheels. A toothed segment upon one frame, 

 and a crank shaft and pinion upon the other, 

 serve to elevate or depress the plows. 



Claim. The balanced frame A, having the 

 gear wheels/ k I bevel wheels g g and spiral 

 plows C, placed at an angle with the ground 

 and projecting forward in combination with 

 the connecting frame T, steering wheels S, 

 toothed segments U, shaft V and pinion W, 

 all arranged and operating substantially as 

 shown and described.

Two or more gangs of plows are arranged 

 upon beams which slide backward and forward 

 between guides. Attached to each plow-beam 

 is a chain passing around its pulley upon the 

 forward wheel shaft. A rigid lever or post on 

 the pulley has an eccentric connection with 

 the geared propelling shaft. The eccentrics 

 are on opposite sides of the latter shaft so that 

 as the machine moves forward the plows upon 

 each beam work alternately. 



Claim. Two or more guided plow-beams C 

 with their attached plows F arranged to be 

 operated in alternation from one main power by 

 means of the chains I, pulley or cranks K lev- 

 ers M, connecting rods O and eccentrics P, all 

 combined and arranged to be driven by the 

 shaft Q, substantially as and for the purpose 

 described.
