SPECIFICATION 'orming part of Letters Patent No. 356,638, dated January 25,1897.

Application filed Decembcr'l', 1885. Serial No. 220,919. (No model.)

To all 10720722, it may concern.-

Be itkuownthat we,Gnoaen HENRY Wamwnrsnr and Pn'rnn JACKSON ROYALL, of Wilson, in the county of \Vilson and State of North Carolina, have invented certain new and useful Improvements in Cultivators; and we do hereby declare the following to he a full, clear, and

exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use it, reference being bad to the accompanying drawings, which form part of this specification.

Ourinvention relates to an improvement in cultivators; and it consists in, first, the corn- :5 bination of the point which is provided with a single ear, lug, or projection, the front also provided with a single ear, lug or projection, and the standard, the ears or lugs of the two parts being made to catch upon opposite sides of the standard and securely fastened in position by means of a single clamping-bolt; sec ond, the co mbinatiou of the shoe provided with openings into which project suitable points,with the wings, which are applied to opposite sides of the shoe and fastened in position by means of suitable clamping-bolts, as will be more fully described hereinafter.

The objects of our invention are to fasten the point on the front of the plow by means 0 of only a single bolt, which is passed through ears formed on the two parts, and'which bear against opposite sides of the standard, and to form points or projections in the openings, so that the clamping-bolts which hold the wings 5 in position will have to catch above or below the points, and thus regulate the height at which the wings are placed and the quantity of earth which is being thrown toward the \plants.

Figure l is a side elevation of a cultivator to which our invention is applied, one of the wings being removed. Figs. 2 and 3 are perspectives of the plow-point and the front taken from their rear sides. Fig. 4 is a horizontal section taken through the standard, showing the pointand the front in position.

A represents the standard; B, the shoe; C, the brace; D, the beam, and E the handles, all

of which may be constructed in any suitable 5o manner. The point G and the front H are made in separate and distinct parts, and each one is shaped on its rear side so as to fit on the front edge of the standard A. The point is provided with a single ear, lug, or projection, Lwhich fits against one side of the standard, and the front is provided with another car, lug, or projection, J ,which fits against the opposite side of the standard, and the point and the front are secured rigidly in position upon the standard by means of a single clamping 6o bolt, L,which is passed through the standard and. the two cars, as shown. The ear, lug, or projection upon the point projects up above the upper edgeof the point, and the ear, lug, or projection upon the front extends down he low the lower ed go of the front, and the openings in these two cars come just opposite the opening through the standard, so that a single bolt can be passed through the three parts, and thus clamp them securely together.

Through the shoe are made the two openings 0, and projecting into the rear side of each of these openings is a point or extension,P, for the purpose of dividing the opening into two parts and causing theclalnping-boltsQ to catch either 7 5 above or below these points, according as the wings are to be raised or lowered, for the purpose of sweeping (more or less) earth toward or away from the plants, as may be desired. Each one of the wings It has its inner end, S, formed so as to bear against and extend parallel with the shoe, and each end is provided with a bolt-hole, through which the clampingbolts Q are passed. The points or projections which extend into the openings at their rear sides serve to compel the bolts to remain either above or below these projections, according to the position in which the wings are adjusted, Should it be desired to raise the Wings upward, so that there will not beso much earth o thrown toward the plants, the bolts are passed through the openings above the points or projections, and these points will prevent the wings from dropping downward in the openlugs.

If ,it is desired to lower the wings so as to move a greater quantity toward the plants, then the bolts will be passed through the openings below theprojections, and these projections prevent the bolt from rising upward in 100 the openings in case the nuts should work slightly loose.

If the points or projections were not used,;

as soon as the nut worked slightly loose upon the bolts the pressure of the earth upon; the wings would be apt to either move them up or down, and hence they would not remainin the position into which they were adjusted.

These points serve to prevent the bolts from either moving up or down in the openingsnine less especially adjusted. v

Having thus described our invention, we claim- 1. The combination of the standard, the point provided with an ear, lug, or projection,

the front provided with an ear, lug, or projection, and the clampingbolt, the ears or; lugs of the two parts being made to catch upon 0pposite sides of the standard, so as to be clamped In testimony whereof we affixour signatures in presence of two witnesses.
