Mound City, 111. Spading Machines. Jan. 

 ii, 1881. Filed May 21, 1880. 



Claim. 1. A spading machine supported 

 upon a wheel carriage, and consisting of a series 

 of spades held in guides and arranged radially 

 around an axle and caused to have a rotary re- 

 ciprocating motion around and from the axle, 

 in combination with a spring mechanism ar- 

 ranged between the axle and spades, whereby 

 the said movement will be retarted as the spades 

 shall enter the ground and accelerated as they 

 are withdrawn from the earth, as shown and 

 described. 



2. In a spading machine, the combination of 

 the supporting wheels, the revolving axle, an 

 independently revolting sleeve to fit around the 

 axle, guide disks attached to said sleeve, sup- 

 porting rotary reciprocating shovels, and the 

 multiple gearing to cause the sleeve and its 

 connections to revolve upon and in the direc- 

 tion with the axle and at an accelerated speed 

 therewith, in the manner and for the purpose 

 substantially as described. 



3. In a spading machine, the combination of 

 the supporting wheels B B, the driving axle A, 

 the hollow sleeve H', guide disks I I', carrying 

 rotary reciprocating spades K, provided with 

 cylindrical hubs that envelop the sleeve H' and 

 are connected therewith by a coiled spring, and 

 a set- screw in the one working in a segmental 

 slot of the other, to limit their movement one 

 upon the other and exert a yielding spring 

 pressure upon the spades as they enter the 

 ground, substantially as described. 



4. The combination, in spading machines, of 

 the supporting wheels B, axle A, sleeve H', 

 multiple gear to connect the axle with the 

 sleeve, guide disks I I', spades K, eccentric L, 

 with grooved periphery /, secured to peripheral 

 rim L' by set-screws / 2 , and segment plates K', 

 pivoted to studs K 2 , that slide in slot in the 

 face of the peripheral rim, in the manner and 

 for the purpose substantially as described. 



5. In a spading machine mounted upon a 

 wheeled carriage, the guide disks I I', support- 

 ed upon a sleeve or axle and carrying rotary 

 reciprocating spades, in combination with the 

 eccentric L, adjustably connected to the frame 

 of the machine by a bail, L 2 , to regulate the 

 thrust of the spades into the ground or to raise 

 them out of contact therewith altogether, sub- 

 stantially as and for the purpose described. 



238,532. JULIUS SCHUCHARD, 



Fredericsburg, Texas. Rotary Spading Ma- 

 chines. Mar. 8, 1881. Filed Dec. 13, 1880. 

 Claim. 1. In a rotary spading machine, the 

 combination of the supporting and draught 

 frame A, transverse axle C, the rotary spading 

 drum D, mounted at one end of said axle, and 

 the traction wheel H at the opposite end there- 

 of, all as and for the purpose set forth. 



2. In a rotary spading machine, the combi- 



nation of the supporting and draught frame A, 

 transverse axle C, the rotary spading drum D, 

 mounted at one end of said axle, the traction 

 wheel H at the opposite end thereof, with the 

 spading drum G, hinged frame I, cleaners J, 

 mounted on axle C, and the cleaners K, all 

 constructed and relatively arranged as herein 

 shown and described, for the purpose set forth. 

 3. In a rotary spading machine, the curved 

 tooth E, having a square chisel point and a 

 triangular cross-section, the concave face being 

 of uniform width, and the thickness of the tooth 

 increasing from the point of the base, as and 

 for the purpose set forth. 



238,970. CHARLES E. SACKETT, 



Matilda Furnace, Pa. Combined Plows. 

 Mar. 15, 1881. Filed Jan. 14,1881. 



Claim. 1. The combination of the pulver- 

 izing wheel, the bent axle, and the land wheel 

 with the plow flexibly suspended beneath said 

 bent axle and discharging into said wheel, and 

 with devices for preventing lateral movement 

 of said plow, whereby vertical movement of the 

 plow and proper relation to the pulvering wheel 

 are maintained, substantially as described. 



2. The combination of the bent axle B, the 

 tongue C, the yoke braces a a, fixed directly to 

 said axle and adapted for connection either to 

 the plow beam or to the tongue, as set forth. 



3. The combination of the plow beam, the 

 yoke braces a a, fixed directly to the axle, the 

 axle B, the pivotal supports 5 5, and the carry- 

 ing frame composed of the jointed tongue C, 

 the diagonal braces 3 3, the re-enforcing braces 

 4 4, and terminating preferably in the frame 6 

 6 to support a seed drill, the whole being bolted 

 firmly together and pivoted to the axle through 

 the supports 5 5, substantially as described and 

 shown. 



4. The combination, with the wheels, the 

 bent axle, and the braces a a, adapted for 

 pivotal connection either to the plow beam or 

 the tongue C, of the described lifting devices, 

 and adapted to raise either the plow or culti- 

 vator teeth, as set forth. 



5. The combination, of the wheels, the bent 

 axle, the tongue C, the hook c, the plow beam 

 with pin p, and lifting levers, substantially as 

 described. 



6. The combination of the wheels, the bent 

 axle D, the lever handles h, the tongue C, and 

 the braces a, said lever handles h being pivoted 

 upon the braces a, as set forth. 



7. The combination of the tongue C, the. 

 guide posts g, fixed to its rear extension, the
