IMPROVEMENT IN, CULTIVATORS.

Specification forming part of Letters Patent No. 56,102, dated July 3, 1866.

To all whom it may concern:

Be it known that we, JOHN S. Bowen. and IRA RowELL, of Beaver Dam, in the county of Dodge and State of Wisconsin,'have invented a new and useful Improvement in (Jultivators; and we do hereby declare the following to be a full, clear, and exact description of the nature, construction, and operation of the same, reference being had to the accompanying drawings, which are made a part of this specification, and in which the figure represents a perspective view of a cultivator-beam with our invention applied.

Similar letters of reference indicate corresponding parts. I

Thisinvention consists in the application to the shank of a brace-bar, which is retained in position by a bolt, which passes transversely through the beam and binds against the curved edge of the brace-bar in such a way as to hold the latter firmly in position as the tooth works its waythrough the yielding soil, but so as to allow the shank to give backward to enable the tooth to override immovable obstacles, a slot being formed in the beam to permit the brace to slide upward through the same when the shank is forced backward by an obstacle.

The following description in detail will enable others skilled in the art to which our invention appertains to fully understand and use the same.

In the drawing, A represents one of the beams of a cultivator; B, the shank, and B the tooth thereof; and O, a curved brace-bar. The upper end of the brace-bar O occupiesalongitudinal slot, at, in the beam A,an d a bolt, D, passing transversely through the beam, binds against the front edge of the brace-bar O and .the'brace-bar O. This arrangement prevents the shank from breaking and enables the parts to be easily readjusted by hand; V

The bolt D may be fitted in a slot in the beam and provided with nuts by which to set it any desired position, to regulate its binding force against the brace and adapt the shank to beadjusted forward or backward for deep or shallow cultivating.

The above-described arrangement may be cheaply applied, is of very simple construction, and has been found more efl'ective practically than other devices designed to operate in a similar way.

Having thus described our invention, the following is what we claim as new and desire to secure by Letters Patent:

The combination of the slotted beam A,

shank B, brace-bar O, and bolt D, when the parts are constructed and arranged to operate as and for the purposes herein specified.
