QFEGIFICATION forming part of Letters Patent No. 337,861, dated March 16, 1886.

Application filed December 10, 1885. Serial No. 185,231.

To all whom it may concern.-

Be it known that I, ARTIE I. PEFFLEY, a citizen of Indiana, residing at Ladoga, in the county of Montgomery and State of Indiana, haveinvented certain new and useful Improvements in IVheeLOultivators; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the let ters and figures of reference marked thereon, which form a part of this specification.

The object of this improvement is a wheelcultivator that is adapted by its construction and operation to a more thorough and efficient service than other implements of its class. These results are attained by the mechanism illustrated in the drawings herewith filed as part hereof, in which the same letters of reference denote the same parts in the different views.

Figure l is a perspective representation of a wheel-cultivator embodying the features of my improvement. Fig. 2 is a sectional detail view of the arch and some connecting parts. Figs. 3 and 4 are details. Fig. 5 is a perspective view of one of the parts detached. Figs. 6, 7, and 8 are details.

A is a metal arch having rectangular extensions made round in form, as shown at A, and provided with sockets a, for a purpose hereinafter set forth. The ends of the extensions A are left square, as shown, and provided with perforations for the purpose of bolting thereto the curved and bent plates B B, which connect with the transporting-wheels B" by means of plates D, suitably secured at d to the parts 13, and affixed by bolts d to a slotted extension ofthe axle-hub E, as more fully shown in Fig. 5.

O C are whiffletrees, pivoted at a between the plates B B.

EE are axles for the transporting-wit eels B Fis a curved bar, pivotally connected at its end f to the arch A, and secured at its lower end to a bifurcated plate, h, provided with a wheel, H.

G is a curved plate, affixed to the arch A, and provided with a series of perforations for the reception of a bolt or pin to be passed through a corresponding perforation in the No model.)

bar F, as occasion may require,'for a purpose to be presently explained.

I I are adjustable connections for the cultivator-gangs K K with the extensions A of the arch A. These adjustable connections I are made in two parts, of suitable formation to be bolted together, as shown at i I in Fig. 3, and to receive the hinge-plates J. and to which the cultivator beams or gangs K are affixed, and which are pivotally secured to the adjustable connections by the bolts 1..

N N are bars pivoted to the gangs K at their upper ends, and provided at their lower ends with sheet-metal disks N, provided with hubs a, which revolve on axles a, and act as fenders and prevent trash and large clods from being thrown against the plants when the implement is in use.

L L are shovel-brakes, fitted, as shown in Fig. 3, to the ends of the drags K, to which they are pivoted at Z. They are provided with a series of perforations, 1', corresponding in position and size with a perforation in the gangs K, provided for the reception of wood pins Z, to be inserted therein through perforations in the brakes L, for the purpose of adjusting the cultivator-shovels M at different angles, as occasion may require. The shovels M are provided with eyes m, which fit over the ends of the brakes L, to which they are detachably secured by set-screw m.

K K are the cultivator-handles, affixed to the beams in the ordinary manner. The arch A is provided with hooked projections a a, for the purpose of engaging with eyes 1) p on the drags K, and thereby hold the same above the ground during the transportation of the implement. The upward movement of the drags will cause the adjustable dragconnections I to turn on the rounded parts A of the arch A. \Vhen the parts are so adjusted, a bolt is inserted through the perforation in the bar F and into the perforation in the plate G, for the purpose of causing the bar F and caster-wheel H to support the'arch in a suitable position for movement from place to place.

The drag-connections I are movablyfitted to the parts A, in order that they may be conveniently adjusted laterally for the purpose of setting the gangs wider apart or closer together, as occasion may require for the cultivation of plant-rows of different widths. The parts I are provided with set-screws i, which are made to enter the sockets a in the parts A,

and thus rigidly secure the adjustment of the gangs K.

The curved plates B and the bent plates B, connected thereto, are pivotally secured to the ends of the arch, and have a limited movement thereon. The plates D, fixed to the axle-hubs E, are pivotally connected to the plates 13, as

shown at d, and allow complete caster movement of the wheels B. By reason of this arrangement and the pivoted connection of the whiffletrees O a change is prevented from being made in the position of the gangs should the draft-animals move to one side or the other of the proper course.

By adjusting the cultivator-brakes on the gangs K with the pins Z inserted through the middle holes the shovels M will run a common depth. By putting the pins in the front holes they will run shallow, and with thepins in the rear holes they will run deep.

The wheel H will have a free caster-like movement that will closely follow the action of the front wheels B and at the same time run in a direct line with the draft of the team. When the implement is in use, the bolt connecting the bar F to the plate G should be removed, to allow the wheel H to adjust itself to the irregularities of the ground without affecting the draft of the shovels.

Having explained the construction and op-
