BENAIAH C. HOYT, OF PORT WASHINGTON, WISCONSIN.

IMPRovEMl-:NTIN PLows.-

Specification forming part of Letters Patent No- 15,654, dated September 2, 1856.

To all whom 'it may concern:

Be it known that I, BENAIAH U. HoYr, ot'

Port Washington, in the county of Ozaukee,

and in the State of Wisconsin, have invented a new and useful Improvement on the Rotary Cultivator-Plow and I do hereby declare that the following is a full and exact description thereof', as Vshown in the accompanying draw l ings.' (See Figures l, 2, 3, 4t.)

The nature of my invention consists, first, in 4the construction ofa plow so as to enable the plowman to turn one or two furrows with'it at the same time; second, the construction ot' a plow so that it may be arranged into a rotary' cultivator without diiculty; and, thirdly, to enable the plowman to increase or diminish the width ot' his work at pleasure.

To enable others skilled in the art to make and use my invention, I will describe its con'- struction and operation.

I commence with thefr'ame It. I make a straight standard,'A, the front edge of which has a Vform. Near the bottom ot' this standard is 'a square bearing, B, which enters` a corresponding hole in the points, Figs. 2 and 3. These points are made fast to the standard by screw and nut, at T, and side bolts, gg. Above the V"t'orm, and about two-thirds the length of the standard Afrom the bottom up, isa projecting piece of iron, C, with a hole through it,

which receives a bearing or hook on thelowerl side and back end ofthe beam D. At the top end of' the standard is a round bearing, U, which receives a plate of iron that is made fast tothe top ofthe beam, togetherwith the cap H.

At a point opposite the projecting piece G,

I start two branches, t2 t3, from the standard A, which I carry up in a curve-line about halt'- way from thestandard A to the slot F, where I bring the upper branch, t3, down and conneet ilrto the lower branch, t2, forming a slot,

r Y, for the bolt Z to work through. From thence I carry the single branch t2 still on and down about half-way from the slotY to the slot F in the back part of thc frame It, where another branch, V, starts up vand back, forming a place forthe location ofthe handles. At the bottom of branch Vth'e frame R starts out in a sharp curve, through which is slot F. From thence I extend the same around in acurve and connect it to the standard A at G. The beam D is constructed of wood, with a strap ot' iron on the top and bottom. The strap on the bottom terminatesin a hook, .which enters the projecting piece C on the standard A. The strap ot' iron on the top of beam D terminates in a wide/plate, a a. It has three holes through it, two of which are to receive screw- 4bolts b b, and the third, which is-between the two, is larger, and is made to Work on the bearing U under the cap H. Thus the beam is hinged to the standard, as described, and put into a position corresponding with the handles and point and made fast by the use of bolts b b, passing through the c ap H in to the .plate a a on the beam. The cap H is bolted to the top bra-moby?, of the frame R. The cap H and the beam D are made secure to the top end gf the standard lA by the use of screw and nut I construct my mold-boards in the followingl manner: Each cnltivator-plow has two moldboards, made nearly ali ke. Th e'y revolve upon a central pivot or axle. The frames thatcontain the mold-boards are made of cast-iron.

Around the hub, or near the center of those trames, start out eight dat pieces ot' iron, something like the spokes of a wagon-wheel, leaving an open vspace between them, as seen at I. The ends ot these short spokes are connected to a band, J. From this band radiate prongs X5, the ends ol which `work in the'earth, .taking a iirm hold on the same, and secures their motion. y These'ames described are concavo-` convex in form. The mold-boards -K K are constructed of thin wrought iron or steel, corresponding in shape to the mold-board trames, into which frames they are placed, andmade fast to `them by bolts ,P P, passing through them into the prongs X5. Y The axles E, upon which the mold-boards revolve, are inclined forward to that degree 4that whenthe mold-board frames 'are hung upon them the convexsides come near together, and are made to work together by means-ot' studs on the back sides of the righ t-hand moldboard fra-me, passing through the open spaces in the left-hand mold-board frame, as seen at L. At the center ot' the axle is an arm, extending back, passing throughl slot F, and is made' secure to the frame R by screw and nut c4. `At l the end of the axle E, I make fast the lower end of braces R7 N, extending them up to slot Y, where I make the top ends fast by the nseof bolt Z. To increase or diminish the width' the axle that passes through slot F in frame R.

The operation of this plow is as follows: To turnbut one furrow, put onto the standard A point M. Make it fast to the standard, as above described. Swingthe beam to the right and the handles to the left until the left handle and beam is on a line with the landside of the point M. To turn two furrows at the same time, put yonto the standard point, Fig. 3. Make the beam and handles fast on a line between the two mold-boards.

To make a cultivator of the plow, put onto the standard point, Fig. 2. Remove the moldboards K K by withdrawing the bolt Z at the top end of braces Rf' N, and also withdraw the short bolts P P, that pass through the moldboards K K into the'prongs X.

Having described the construction and operation of myrotary cultivator-plow, what I claim as rnv-invention, and desire to secure by Letters Patent, is

The adjustable rotary mold boards K K, combined with beam D and frame R, the whole being arranged in the manner and for the purpose set forth.
