HAND GULTIVATOR OR PLOW.

Specification of Letters Patent.

Patented Aug. 11, 1908.

Application filed July 29, 1907. Serial No. 386,064.

To all whom it may concern:

Be it known that I, CLAYTON D. HIME- 'BAUGH, a citizen of the United States, residing at the city of Burr Oak, county of St. Joseph, State of Michigan, have invented certain new and useful Improvements in Hand Cultivators or Flows, of which the following is a specification.

This invention relates to improvements in hand plows or cultivators.

The objects of the invention are to provide a very simple and strong frame-work on which both the wheel and the tooth or plow are conveniently adjusted to different heights and to different angular relations to each other, the economy of manufacture and strength of the parts, and their ready adjustability, being the things accomplished.

I accomplish the objects of my invention by the devices and means described in the following specification.

The invention is clearly-defined and pointed out in the claims.

A structure embodying the features of my invention is clearly illustrated in the accompanying drawing, forming a part of this specification, in which:

Figure 1 is a side elevation view of a hand plow or cultivator embodying the features of my invention. Fig. 2 is a vertical sectional view on line 2-2 of Fig. 1, showing the method of attaching the wheel to the frame and of adjusting the same. Fig, 3 is a sectional view taken on the irregular line 33 of Fig. 1, showing the method of supporting and securing the plow or tooth to the standard. Fig. 4 is an enlarged detail sectional view taken on line 4-4 of Fig. 1, showing a further detail as to the connection between the lower part of the standard and the frame. Fig. 5 is a detail sectional view, taken on a line 55 of Fig. 3, showing the method of attachment of the shoe or plow to the lower end of the standard.

In the drawing, the sectional views are taken looking in the direction of the little arrows at the ends of the section lines and similar numerals of reference refer to similar parts throughout the several views.

Referring to the numbered parts of the drawing, the main portion of the frame consists of the handle bars 1 which extend downwardly and forwardly and are curved on substantially a circle at 1' and have a rearwardly-extending portion 1 which in effect corresponds to the beam of a plow. This bar is folded on itself at the lower end of the beam part, whereby the whole is formed of a single piece, so that there is no need of connecting the two sides together; and it insures a perfect correspondence of the various symmetrical parts.

The handle 6 is secured by bolts 6 6 to the rear ends of the bars 1. Extending vertically across each side bar 1 are vertical bars 7, between which is carried the wheel 2. The wheel 2 is provided with a hub 3 which turns on a suitable sleeve 4 constituting a bearing therefor, the sleeve being slightly longer than the hub on the opposite sides of the frame which are clamped tight to the sleeve by a bolt 5 therethrough.

The position of the wheel can be varied by the series of holes 5 5 through which the bolt -5 may be inserted in clamping the wheel and its journal in place. The osition of the wheel may be shiftedback an forth and varied slightly in its elevation, and the adjustment of the bars 7 by means of a bolt 9 and a series of holes 9 at the bottom, and by the sliding contact of the upper ends of the bars 7 where the bolt 8 is inserted through the slot 8 in the same. The shifting backwards and forwards of the upper end of this bar 7 is accomplished by the'bolt 8 being inserted in a series of the bolt-holes 8 8".

The standard 10 consists of a bar folded upon itself and secured between the handle bars 1 at the upper end by the bolts 11, entering slots 11 therein; and the tilting of the standard is effected by a series of holes 11.

The double bar of the standard 10 extends down each side of the rear end of the beam part 1 where it is folded upon itself and is secured thereto by a single bolt 12 therethrough, which permits the setting of the standard at different angles in relation to the said beam part by the adjustment back and forth of the upper end of the standard as above referred to. The folding of this standard 10 u on itself affords a strong brace for the hand e bars and tends to make the same stiff and rigid.

The cultivator tooth or plow 13 is secured to the bottom end of the standard 10 by a bolt 14 extending through the said tooth and between the pair of bars constituting the said standard 10, clamping the end to the piece, and the various parts are adjustable rear of the same. The lower ends of the bars are secured together by a bolt 15 which clamps them onto a spacing washer 16.

It will thus be seen that all of the various parts constituting the frame work of my improved hand cultivator or plow are simple to manufacture, simply being formed of flat bar iron, which has been suitably bent and per forated for receiving ordinary cheap stovebolts. The handle isvery securely attached by bolts therethrough and the adjustment of the various parts, both as to height and an-' gle of the plow or cultivator, is regulated simply by a series of erforations in the fiat bars which make upt 1e parts.

While cultivators of similar form have been produced before, they have been quite elaborate in their details, containing pivot jointed frames for the effective adjustment of the height and angle of the plow or cultivator, and in their relation to the other parts, making them expens'iveto manufacture and cumbersome to operate and producing weak structures; whereas, the struc ture here produced is very strong because the handle bars and beams are a continuous thereon by a series of holes therethrough, to which the parts are directly and securely bolted. The result is a very strong cultivator or plow, containing all adjustment necessary, Which is very easy to manufacture.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:

1. In a hand-cultivator tool, the combination of handle bars formed of parallel portions of metal bar which extend downwardly and forwardly and are curved downwardly and rearwardly to form a beam-portion; a handle secured to the rear of said handle bars a vertically adjustable brace bar extending across the curved portions of each handle bar and beam portion; a sleeve-bearing adjustably sup orted on the said brace bars by a suitab e bolt therethrough; a

wheel on the said bearing a standard secured by a suitable bolt to the rear of said 1 beam portion extending upwardly across the said handle bars and secured thereto adjustably by a bolt through a series of holes whereby its angle is varied; a cultivator tooth secured to the bottom of said standard, coacting for the purpose specified.

2. In a hand-cultivator tool, the combination of handle bars formed of parallel portions of metal bar which extend downwardly and forwardly and are curved downwardly and rearwardly to form a beam-portion; a handle secured to the rear of said handle bars; a brace bar extending across the curved portions of each handle bar and beam portion; a sleeve-bearing adjustably supported on the said brace bars by a suitable bolt 'therethrough; a wheel on the said bearing a standard secured by a suitable'bolt to the rear of said beam portion extending upwardly across the said handle bars and secured thereto adjustably by a bolt through a series of holes whereby its angle is varied; a cultivator tooth secured to the bottom of gaid standard, coacting for the purpose speci- 3. In a hand-cultivator tool, the combination of handle bars formed of parallel portions of metal bar which extend downwardly and forwardly and curved downwardly and rearwardly to form a beam portion; a handle secured to the rear of said handle bars; a brace bar extending across the curved portions of eachhandle bar and beam-portion a bearing supported on said brace bars; a Wheel on said bearing; a standard secured by a suitable bolt to the rear of said beam portion extending upwardly across the said handle bars and secured thereto by a bolt; a cultivator tooth secured to the bottom of said standard, eoacting for the purpose specified.

In witness whereof, I have hereunto set my hand and seal in the presence of two witnesses.
