.AZ-Zv rne as SAMUEL H. OAWLEY, OF EL DORADO, OHIO.

SULKY-HARROW.

SPECIFICATION forming part of Letters Patent No. 289,616, dated December 4, 1883.

Application filed July 28, 1883. (No model.) v

To all whom it may concern:

Be it known that. I, SAMUEL H. OAWLEY,

a citizen of the United States, residing at El able others skilled in the art to which it ap-- pertains to make and use the same, reference being had to the accompanying drahvings, and

to the letters. and figures of reference marked thereon, which form a part of this specification.

vMy invention relates to harrows, and more particularly to that class known as wheel or sulky harrows, the object being to provide means for raising the harrow from the ground when not in use.

A further object of the invention is to provide aharrow which maybe so constructed and arranged as to be operated forward or backward.

The invention consists in the improved construction and combinations of parts hereinafter fully described, and pointed out in the claims.

In the drawings, Figure l is a perspective View of my improved harrow. Fig. 2 is a plan view of the same, and Figs. 3 and 4 are detached views.

A A represent the harrowsections, the beams of which are secured together at their rear and forward ends by rods or braces on a, and provided at their front and rear ends with hooks a oi, for the attachment of the sulkyframe.

B B represent the wheels of the harrowsulky, loosely mounted upon an axle, b, and adapted to run between the beams of the harrow. Upon the axle b, and at about the center, of said axle, is rigidly mounted a disk-lever;b4,- which is connected to the draft-tohgue Ocby a depending loop, 0'.

D D represent plates secured to the beams V of the harrow, their inner sides being bent at right angles to the plate, and provided with perforations d d, for the attachment of slotted arms (2 which are attached at their other ends to the disk I). To the draft-tongue G is secured a perforated bar, d*, which is adapted to receive a pin or stop, (1 which holds the harrow above the ground'when not in use.

nect with the crank-arms e e. rangement the weight of the operator, in a E represents the seat, which is mounted on a bar, 0, secured at one end to the under side of the seat and at the other end to the drafttongue 0. p

e e represent braces for the seat,which con- By this armeasure, overcomes the'weight of the harrow in lifting the same. The crank-arms e 6* are secured at one end to the'axle b, and loosely secured at their other ends to the outer beams, c 6 of the sulky-frame.

F represents alever rigidlymounted on the axle b, and adapted to raise or lower the harrow-frames, as desired.

f f represent plates secured to the beams near the outer sides of the barrow-frames, and perforated, as shown, for the attachment of a slotted arm, f which is pivotally secured to the crank-arm f The crank-arm f 4 is rigidly mounted on the shaft 1).

G represents the sulky-frame, consisting of the bars 9 g, which are pivotally secured to the crank-arms e c, said bars being secured between the horizontal bars H H. The bars 9 g are braced by a horizontal rod or bar, h and two diagonal bars h h I represents a bail or loop bent around the draft-tongue O, the ends being secured to the horizontal bars H H.

J J represent a series of diagonal slats connected to hooks,which aresecured to the ends of the harrow-beams and pivoted betweenthe horizontal bars H H. By the use of the slats J J the harrow-frames will adapt themselves to uneven surfaces without interfering with the sulky.

It will be apparent by the construction shown and described that by detachingthe slats J J and the crank-arms the sulky-frame may be reversed and secured at the rear ends of the harrow-frames.

It will also be seen that the construction affords a ready means for raising the harrowframes from the ground when not in use.

When it is desired to raise the harrow, the

-1ever F is thrown forward, thus turning the axle Z2 and raising its crank-arms f which latter are connected by the links f to the harrow-plates f f. The disk I) also assists the raising of the harrowthrough the medium of ends to crank-arms rigidly secured at the ends of the axle, and a disk rigidly mounted on the the links d which latter are connected to the central plates, D, of the harrow.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, isg 1. In a harrow, the combination, with the sections A A, of an axle havingwheels mounted thereon and provided with arms for its attachment to the harrow-sections, and a disk rigidly mounted on said axle, the draft-tongue G, secured to the disk by a depending loop, a bar mounted on said draft-tongue, at the rear end of which is secured a seat, and braces secured to the under side of the seat and connecting with the crank-arms e e, substantially as set forth.

2. In a harrow, the combination, with the sections A A, the beams of which are provided with plates for the attachment of slotted arms which are pivotally secured at their other axle, of a tongue-bar secured to said disk by a depending loop, a bar, 6, upon which is secured a seat, and which is provided with a slot adapted to receive a perforated plate secured to the tongue-bar, and a pin adapted to fit the perforations of said plate, substantially as set forth.

3. In a harrow, the combination, with the axle and the sulky-frame, consisting of the bars 9 g, pivotally secured to the crank-arms e e, the bars If, h, and 71, and the horizontal bars H H, having a bail secured to the tonguebar 0, of a series of crossed slats pivoted between the bars H H, and connected to the beams of the harrow by hooks or other analogous means, substantially as set forth.

In testimony whereof I affix my signaturein presence of two witnesses.

SAMUEL H. OAWLEY. Witnesses:
