of double cranks, arranged to move in reverse 

 directions, and giving a compound action to 

 the spade or spades, essentially as specified. 



2. Providing the spade stock or holder with a 

 spring stop or stops, so constructed and arran- 

 ged as to be capable of being thrust away or to 

 one side of the spade in its descent or digging 

 stroke, to avoid striking a stone or other inter- 

 vening obstacle calculated to injure it, and 

 permitting of the yield or rise of the spade there- 

 from, substantially as shown and described. 



3. Constructing and arranging the spade stock 

 or holder, as shown and described, with a twist 

 screw or helical groove, or the equivalent there- 

 of, so that the spade, in its reciprocating or 

 longitudinal travel, shall, at a certain point or 

 points thereof, be turned and made to assume 

 different positions relatively to the line of cut, 

 essentially as set forth. 



4. Causing the spade, after it has been pushed 

 into its stock or holder by meeting with an 

 obstacle in its descent, to be automatically re- 

 turned to its proper position for further work, 

 during the retreat of the holder, by means of 

 the same device or pin which, in connection 

 with the helical slot in the stock, serves to turn 

 and alter the position of the blade of the spade 

 relatively to the line of cut, essentially as des- 

 cribed. 



5. Constructing the spade or spade blade 

 with an articulation joint, for action when in 

 the soil or when freeing itself therefrom, and, 

 during the backward thrust or throw of the 

 spade, to avoid injury or breakage from stones 

 or other like obstacles in the soil.

Littleton, N. H. Steam Plows. Dec. 11, 



i860. 



Claim. 1. The arrangement of the levers 

 G G, sliding pinions //, on shaft F, and the 

 gearings I I k k, on the shafts F J, essentially 

 as shown, whereby the plows K 1 may be rotated 

 or stopped instantly at the will of the operator 

 or attendant. 



2. The arrangement of the levers R R, with 

 pawls /and lips u attached, the ratchet Q on 

 the hollow shafts N N, the clutches/ q, gearing 

 P on the shafts O, on which the hollow shafts 

 N are placed, and the ropes or chains u n at- 

 tached to the cross bar M of the arms k, essen- 

 tially as shown, for the purpose of elevating the 

 shaft J and its plows K 1 when desired. 



30,986. JOHN REYNOLDS, New York 

 N. Y. Steam Plows. Dec. 18, i860. 

 Claim. 1. The arrangement and combina- 

 tion of the plow frame A with plows A 1 vertical 

 slotted standards c, link d, rock shaft ef, groved 

 disk crank g link d x chains, or cords J J 1 and 

 windlass shaft K, substantially in the manner 

 and for the purpose described. 



2. The arrangement and combination of the 

 fast spur wheel R, sliding lever clutch T / / and 

 loose wheels C u u v v, substantially in the 

 manner and for the purpose described. 



3. The arrangement of the plow frame A, 

 with the plows A 1 boiler D, engine cylinder D 1 



wood receptacle F F 1 F 2 water tank E, specified 

 mechanism for throwing the engine in connec- 

 tion with the carriage B, and the mechanism 

 specified for supporting and adjusting the plow 

 frame and plows, the whole constructed and 

 operating together in the manner described.

 Eng., assignor to William Penn Tatham, 

 Philadelphia, Pa. Machines for Cleaning 

 Lands. Patented in Eng. Sep. 8, 1856. 

 Apr. 9, 1861. 



This invention relates to an improvement in 

 plows which are operated by steam power and 

 is applied to a machine having two gangs or 

 plows, attached to and carried by a tilting frame 

 which vibrates on an axis, so that when one 

 gang is brought down into action the other is 

 lifted up clear of the land. The invention 

 consists in combining with the above a steering 

 apparatus, by a mechanism which enables the 

 operator while riding on the machine to change 

 at will the direction of the motion in plow- 

 ing. 



Claim. Combining the pulley on the anchor 

 carriage, which receives motion from the en- 

 gine by the pulling of the plows or other im- 

 plements, with the drum that operates the 

 anchor rope by means of the intermediate 

 mechanism described, or any equivalent there- 

 for, as described and for the purpose set forth. 



32.026. JOHN FOWLER, JR. Leeds, 

 Eng. assignor to William Penn Tatham, 

 Philadelphia, Pa. Machines for Plowing 

 Lands by Steam. Patented in Eng. Sep. 8, 

 1856. Apr. 9, 1861. 



This invention relates to that class of ma- 

 chines for plowing by steam power in which 

 the locomotive engine moves at intervals along 

 one edge of the field, and ropes pass from the 

 engine to and around a pulley attached to an 

 anchor moved at intervals along the opposite 

 edge of the field. The object of the invention 

 is to move the anchor by the power of the en- 

 , gine at the opposite of the field, by combining 

 with the pulley on the anchor carriage around 

 which the rope passes to operate the plows, and 

 with the drum of a rope connected with an 

 anchor an interposed mechanism to operate 

 the said drum at the required intervals to ad- 

 vance the anchor carriage by the motion of the 

 pulley derived from the engine. 



Claim. Combining with the central pair of 

 sustaining wheels and with frame which carries 

 the two gangs of plows or other tilling instru- 

 ments a seering apparatus, substantially as de- 

 scribed.

 ling Lands. Patented in Eng. Feb. 28, 1856.

Claim. 1. Mounting two gangs of plows or 

 other tilling instruments in suitable frame-work 

 and connecting them with a pair of sustaining
