ACULTIVATOR.

SPECIFICATION forming part of Letters Patent No. 472,813, dated April 12, 1892.

I I Application filed November 12, 1891. Serial No. 411,700. (No model.)

the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same. 7

My invention has relation to improvements in cultivators; and it consists in the peculiar construction, certain novel combinations, and the adaptation of parts hereinafter described and claimed.

In the accompanying drawings, Figure 1 is a perspective view of my improved cultivator, and Fig. 2 is a front elevation of one depending foot removed.

Referring by letter to the said drawings, A indicates the beam of my improved cultivator, which comprises the forwardly-converging branches B, which are connected together at their forward ends and receive between them a clevis O, which may be of the ordinary or any approved construction. The forwardlyconverging branches B of the beam A are also connected together at an intermediate point in their length by a transverse bolt D, the ends of which extend laterally from the beam branches and are vdesigned to take through the lower ends of the handle-bars E, which are held thereon by suitable nuts d, as illustrated. These handle-bars E,wl1ich preferably diverge upwardly, as illustrated, are connected together at an intermediate point in their length by a transverse bar a and are braced adjacent to theirlower ends by straps the beam branches and straddling the same nected at their lower ends.

are the depending feetGof myimproved cultivator, which respectively comprise the parallel branches formed integral or rigidly con- Pivotally connected between the upper ends of the branches of the feet G are the gravitating pawls I-I,which are designed to engage the rack-teeth of the beam branches and fix the position of the feet with respect to the said beam branches, whereby the depth of the furrows made by the plows or teeth carried by the said feet may be readily regulated. Taking transverse 1y through the parallel branches of the feet G, beneath andadjacent to the beam branches B, are transverse bolts K, which have their ends threaded to receive nuts L, through the medium of which the branches of the feet may be made to bind against the beam branches and by frictional contact serve to assist the gravitating pawls in holding the feet in their adjusted positions. These transverse bolts K,in addition to the function described, serve to limit the forward adjustment of the lower ends of the depending teeth by engaging the forward edge of the downwardly and forwardly curvedbranches ofthe beam branches.

By the construction described it will be readily perceived that the feet may be readily adjusted and fixed at various angles with respect to the beam branches, so that the plows or teeth carried by said feet will cut a deep or shallow furrow, as desirable.

By the provision of the peculiar construction of feet described it will be readily perceived that the plows or teeth may be readily and adj ustably connected to the said feet.

Although I have specificallydescribed the construction and relative arrangement of the several parts of my improvedc'ultivator, yet I do not desire to be confined to such precise construction, as such modifications may be made as fairlyfall within th'escope of my invention.

Having thus described my invention, what I claim, and desire to secure by Letters Patcut, is

In a cultivator substantially as described,

the combination, with the beam consisting,-

essentially, of the forwardly converging branches connected at their forward ends and having the downwardly and forwardly curved branches at their rear ends and rack-teeth on their upper edge adjacent to their rear ends, of the feet comprising parallel branches pivotally connected to the ends of the downwardly and forwardly curved branches of the beam branches, the gravitating pawls pivoted between the upper ends of the feet branches 7 and adapted to engage the rack-teeth of the beam branches, and transverse bolts connecting the feet branches at a point beneath and adjacent to the beam, substantially as and 10 for the purpose set forth.

In testimony whereof I affix mysignature in presence of two witnesses.

LEON E. PONTON.
