IMPROVEMENT lN COTTONGULTIVATORS.

Specification forming part of Letters Patent No. 29,877, dated September 4, 1860.

To all whom 'it may concern:

Be it known that l, \V. W. GOLSAN, of Autaugaville, in the county of Autauga and State ofAlabama, have invented a new and Improved Agricultural Implement, which may be termed a Cotton-Plant ThinningA and Uultivating Machine; 7 and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, which form a part ot' this specification.

Figure l is a side view of said machine; Fig. 2, a top view, and Fig. 3 a rear view, ot' the same.

Similar letters indicate corresponding parts in each of the drawings.

The frame of my improved machine for thinning out and cultivating cotton-plants may be constructed in the manner represented in the drawings, or in any other that may be deemed expedient.

A rectangular frame composed of the parallel longitudinal beams B B and the transverse end beams, C D, forms the main portion of the frame-work of said implement. The ends ofthe hindmost transverse beam, D, of said frame project a short distance beyond the side beams, B B, thereof, and those ends are securely combined with the central portions of the uprights F F. The forward ends of the shafts of the guiding-handles E E of said implement are combined with the outer sides of the frame-beams B B, and near their after ends the said handle-shafts are securely united to the upper ends ofthe uprights F F. The lower ends of the nprights F F are forked for the reception ot' the bearing-rollers g g.

A transverse beam, H, is securely bolted to the under side of the front transverse beam, C, of the aforesaid rectangular frame B B CD, and the two short beams G G, .which project rearwardly and incline outwardly from their connection with the said transverse beam H, are securely bolted to the under side of the' front portions of the frame-beams B B. An open three-sided frame, which is composed of the transverse beam K and the in wardly-nclinin g side beams, J J, is connected by means of hinges with the after ends of the beams G G; or the said frame may be hinged to the beams B B in case it should be deemed expedient to dispense with the beams G G and Hin constructing the frame otl said implement.

A slotted vertical plate, j, rises from the center ot' the beam K close by the after side ofthe beam D of the frame BB C D, and by means ot` the screw 7c, which passes through the slot in the said plate j into the said beam D, the rear end of the frame K J J can be secured in any de sired position.

Metallic ears i are secured to thcoutersides of' the aforesaid beams J J, and descenda short distance below the same, which ears are perforated for the reception of the handles ff of the laterally-reciprocating hoes L h, as shown in the drawings.

The shank m of cultivator-point L is secured by means of suitable fastenings to the central portions ot' the beams C and H and the front end of the machine, and immediately in the rear of the said cultivator-point a large driving-wheel, A,r is placed', the shaft n of said wheel working in journal-boxes which are secured to the under side ot' the frame-beamsB B.

An annular series of teeth, p, project laterally from each-side of the arms or disk of the driving-wheel A, which series of teeth gear into the teeth of the pinions b b on the front ends of the parallel crank-shafts a a, whose journal-boxes are supported by lugs c c, that project from the innersides of the frame-beams BB, all as represented by Fig. 2 ot' the drawings. shafts a a are connected to the inner ends ot' the hoe-handles f f through the medium of the arms e e, as shown in Fig. 3. lt will therefore be perceived that the rotation of the drivingwheel A will impart a series of laterally-reciprocating movements to the hoes h h. By placing the cranks d d in the proper positions before attaching them to the arms e e on the inner ends of the hoe-handles the hoes will gradually ascend during their outward movements and gradually descend during their inward movements.

I contemplate using the hoes h 7L in the first place for the purpose of thinning out the supcriuous cotton-plants in the tield-rows-an operation well known to all cotton-planters, and one by which only such a number of cotton-plants are left standing in the rows as can be judiciously cultivated 3 and to do this I em- The cranks d d on the after ends of the ploy sharp hoes of the proper width and combine them With handles whose length bears such a relationv to the distance between the rows of cotton-plants to be operated upon as will enable the said hoes to perform the Work required of them. I next use the reciprocating hoes h h for cultivating purposes, or for the purpose of drawing the earth up to the sides of the standing cotton-plants, and for performing this function it may perhaps be advisable to use hoes of a different shape from thoseemployed for thinning out the cotton-plants, andthe said cultivating-hoes will also requirelonger handles than are furnished to the thinningout loes.

Instead of the rollers gg at the lower ends of the uprights F F, it may be expedient to sometimes combine cultivator-points with said uprights.

The adjustabilily of the hinged frame KJJ enables the operator to canse the hoes h h to descend to any desired depth into the ground. The action of the said hoes may also be varied by varying tliele-ngth of the cranks d d. When the said machine is employed for thinning-ont purposes in a cotton-held the front cultivatorpoint, L, serves the purpose of forming a clear and distinct guiding -path for the drivingwheel to run in, which guards the machine against lateral vibrations and insures perfect steadiness of movement.

I do not intend to limit the employment ot' my said improved agricultural implement to coLton-iields, as it may be found to Work admirably well as a corn-cultivator and for varions other purposes.

What I claim as my invention, and desire to secure by Letters Patent, is

The arrangement of the cultivator-point L and the central driving-wheel, A, with the crank-shafts a a, the laterally-acting hoes h h, andthe uprights F F, substantially in the manner and for the purpose herein set forth.

W. 'W. GOLSAN.
