SPECIFICATION forming part of LettersPatent No. 695,499, dated March 18, 1902. Application led October 5, 1901. Serial No."7'7,709. (No model.)

To all whom it may oon/cern: l

Beit known that we,'JAMEs A. D. SHEE- FIELD and JOHN C. SHEFFIELD, citizens of the United States,residing in the county of Houston and AState'of Texas, have-invented a new and useful Oultivator-Plow, of which the following is a specification; l

Our invention is an improved cul'tivator-I plow, especially adapted for cultivating cotton and other crops; and it consists inthe peculiar construction and combination of devices hereinafter fully set forth and claimed.

In the accompanying drawings, Figure 1 is a perspective view of a cultivator-plow'constructed in accordance with our invention. Fig. 2 is partly a side elevation and partly a sectional view of the same. Fig. 3 is adetail perspective view of one of the adjustingplates used on the beam for securing the standard brace-links at-any desired adjustment of the standards. Fig. 4 is a detail perspective View `of onelofthe clamping-links used forsecuring theshovels orpoints to the standards, Fig. 5 is a similar'view of one of the foot-blocks used in the same connection.

The beam Al is preferably made of wood and is provided at'its front end with the usual clevis 2. The handles 3 have their front ends connected to opposite sides of the beam by a bolt 4. A rung 5 connects therear portions of the handles together. A kwheel` is disposed under the rear portion of the beam and is mounted in a standard?, which iscomposed of a pair of bars 7?, which bear against opposite sides of the beam, are connected.

thereto by a bolt 8, which'passes through openings in said bars and beams, and the upper ends ofthe said bars 7a are bent outwardly, as at 9, and provided with adjustingopenings 10. Bolts 11, which are fitted in openings with which the-handles 3 are provided, pass through appropriate openings 10 and secure thesaid standards 7 at any desired angle with relation to the beam, and this construction and combination of devices also enablesthe handles tobe adjusted vertically, so that their rearA ends may be disposed at any desired height to suit Jthe plowman. The bars 7 have adjusting-openings`12 in their lower portions to receive the bolt 13 or spindle on which the wheel 6 revolves, and hence `the latter maybe adjusted vertically in the standard 7,`as willbe understood.

Our improved cultivator-plow is provided with a plurality of standards 14 to carryshovels or points 15, which may be of any suitable construction and shape. The standards 'are disposed one in advance of the other and "in line with each otherand with the Wheel 6. Each of the said standards is composed of a pair of bars 14, which are connected together' at their lower ends andthe upper endsof which are bent outwardly in opposite directions, bear against opposite sides of the beam 1, and are secured thereto by bolts 16, which pass through openings in the upper portions of said standard-bars at points above and below the' beam, hence clamping the standards to said beam without weakening the latter by passing the bolt therethrough. B y loosening the nuts on the said' clamping bolts the said standards may be adjusted to any desired inclination, as will be understood. i

On the beam 1, at suitable distances in ad- Vance of the respective standards-14,"are secured adjusting-plates 17.- The saidad'justin g-plates`have thei r` upper sides corrugated `thebealn by bolts 23, which lpass below the beam, and bolts 24, whichpass above the beam,and engage appropriate corrugations in the adjusting-plates 18. The said bolts and the said adjusting -plates enable the said brace-links to be shiftedlongitudinally on the beam to dispose and secure the standards 14 at any desired angle. l

Foot-blocks -25.are secured between the lower ends of the bars 14a of each standard 14 bybolts 26. The said foot-blockshave laterally-extendin g shoulders 27- at their lower front corners which -bear on the front edges` of the standard-bars 14a.vv The shovels or points 15 are disposed on the front side of the said foot-block and atltheir upper lportions bear against the front'sides of the standards Aroo H. Clamping-links 28, which are provided at their front ends with T- heads 29 and at their rear ends with laterally-extending eyes 30,'are disposed between the bars 14a of standards 14, and their T-heads 29 are adapted to bear on the upper sides of the said shovels or points. The bolts 31, which are employed to clamp the shovels or points to their standards, pass between the bars of the latter through the eyes 30 of the clamping-links, and their nuts or taps 32 bear against the rear sides of the said eyes 30. Hence the said bolts coperate with the said clamping-links to secure the points or shovels against vertical displacement on the standards and enable the said points or shovels to be adjusted vertically and clamped to the standards at any desired point.

By attaching appropriate points or shovels to the standards our improved plow may be used for barring off between the rows of plants and sweeping earth up toward the plants when cultivating a cotton crop. Our improved plow may be also used, when provided with appropriate points or shovels, for bedding and listing the soil or for banking or breaking out the rows. It will be understood that by appropriately adjusting the standards and the wheel 6 the points or shovels may be caused to run in the soil to any desired depth. The wheel 6, which operates in the furrows in rear of the points or shovels, materially lessens the labor to the plowman. At the end of a row, before turning, the handles should be depressed to elevate the points or shovels,there by supporting the plow entirely upon the wheel 6,when the plow may be readily turned without appreciable effort on the part of the plowman. The wheel 6, which operates in rear of the plow, also enables the plow to be readily moved to any part of the field without permitting the points or shovels to cnt the surface of the soil. By

having the points or shovels and the wheel in line with each other and directly in the line of draft under the beam the plow is enabled to run veryrsteadily and evenly without deviation from a straight line and is adapted to be readily guided.

Our improved plow is exceedingly cheap and simple, is very strong and durable, and is entirely practical and efficient in operation.

Having thus described our invention, we claim l. In a plow, the combination of a beam, handles pivotally connected at their lower front ends thereto, a standard comprising a pair of bars, disposed on opposite sides of the beam and pivot-ally connected thereto, the upper ends of said bars being adjustably attached to said handles, and a wheel mounted between the lower portions of said bars, substantially as described.

2. In a cultivator-plow, the combination of a beam, a standard having its upper end forked, to provide arms which bear against opposite sides of the beam, clamping-bolts connecting said arms above and below the beam, whereby the upper end of the standard is adjustable longitudinally of the beam, an adjusting-plate on the latter, notched on its upper side, a brace-link connected to said standard, extending forwardly and upwardly therefrom and provided with arms which bear against opposite sides of said beam, and bolts connecting said arms and extending transversely above and below the beam, the upper of said bolts engaging said notched adjusting-plate, substantially as described.

In testimony that we claim the foregoing as our own we have hereto aixed our si gnaturcs in the presence of two witnesses.
