 the exact depth desired in practice, and to re- 

 lieve the a.ilo and coupling-box from the fric- 

 tion upou the axlo incident to tho downward 

 pressure of the spring .uder the ordinary 

 arrangement. 



With these ends in view the invention con- 

 sists in iutrodncing between the aim of the

 ated by a beam-lifting spring, and a suspeii 

 siou-spring betwppii tho two arms, substan- 

 tially as shown.

It has become common to use springs in 

 cultivators for the purpose of partially sup- 

 porting the plow-beams when in use, the tend- 

 dency of such springs being to elevate the 

 beams : hence, if the operator wishes to press 



the beams aownwardtoplow deeper, ho has to 

 overcome the tension of the springs. 



The objectof my invention is to provide cul- 

 tivators with spiingsconnected with the beams, 

 whioli springs will be free to act jit all limes, 

 but which, when the shovels are in the ground, 

 will not operate so as to have a tendency to 

 elevate tho rear ends of the beams, but when 

 the rear ends of the beams are raised a little 

 will come into action and will raise and hold 

 or assist iij raising and holding the shovels 

 ont of the ground. A further object is to so 

 arrange the sprin^^s that if desired they can 

 also be used for the purpose of aidiog in hold- 

 ing the shovels in the ground. These objects 

 I accomplish by means of coil-springs — one 

 for each beam — the npper end of each spring 

 beiug secured to the mainframe, and the lower 

 end being provided with a pulley which trav- 

 els longitudinally under and along a rod or 

 track connected at the ends to the beam, as 

 hereinafter more fully set forth. 



Tho combination, in a cultivator, of the axle 

 with the swinging shovel-beams B, the spring.*^ 

 secured at their npper ends to the axle aud 

 at their lower ends provided with pulleys or 

 rollers, and the rods c, secured to the shovel- 

 beams and passing over the said rollers, said 

 members being constructed aud adapted for 

 operation substantially as described.

Tbe invention relates to an improved man- 

 ner of constructing the frame and applying 

 '.ho springs for the purpose of raising or assist- 

 i ingtheoperatortoraisethe beams or drag bars, 

 the springs having in some cases the addi- 

 tional function of holding the shovels to their 

 proper places in the ground. 



Tho improvement consists mainly in provid- 

 ing the frame with axles capable of rotating 

 Independently of the wheels, coupling the 

 wheels directly to said axles, anil providing 

 the axles with arms arrauge<l to cooperate 

 with a spring, a weight, or with draft devices 

 to which the team is attached, as hereinafter 

 more Adly explained. 



As regards the combination of the loosely, 

 revolving axles with the beams, and lifting 

 springs Qr other equivalents, the invention ie 

 designed more particularly as an improvement 

 upon those machines in which the axle is sta 

 tionaiy and the beams and springs combined 

 with sleeves or coupling-box«s arranged to ro- 

 tate apon the axles. 



One of the primary objects of the iuventioo 

 is to 8T0id the use of the rotating sleeves oi 

 hoses mounted upon the axle^ which, for va- 

 rioos reasons unnecessary to wetail, are oper 

 to seiious objection.
