SULKY-HARROW.

SPECIFICATION formingpart of Letters Patent No. 246,763, dated September 6, 1881,

Application filed July 9, 1881. (No model.)

To all whom it may concern:

Be it known that I, WILLIAM HANNUM, of Mount Gilead, in the county of Morrow and State of Ohio, have invented a new and useful Improvement in Snlky-Harrows; and I do hereby declare that thefollowingis afull,clear, and exact description of the same, reference being had tothe accompanying drawings, forming part of this specification, in which- Figurel is a plan view of my improved sulkyharrow. Fig. 2 is a rear elevation.

My invention relates to improvements in sulky-harrows; and it consists of a harrow composed of two wings or sections hinged to each other, provided with guide-rods and suspended froin the axle, and three independent shafts journaled in standards secured to the axle, and provided with levers and eccentrics carrying chains secured at their lower ends to the barrow-sections near their outer andinner edges, whereby the central portion of the harrow or either barrow-section can be raised or lowered independently of the other section to avoid obstructions, or both sections can be raised or lowered when desired, as hereinafter more fully set forth.

In the accompanying drawings, a arepresent the wheels of my improved sulky-harrow, connected together by the axle Z), in the usual manner.

0 represents a frame, secured to the under face of the axle by means of uprights or standards (I, cut away and rounded from their middle to their lower ends, and screw-threaded near theirlower ends, and passed through holes in the axle and frame 0.

e 6 represent nuts secured to the lower ends of the threaded standards (7, by which construction the sulky-frame is securely attached to the axle.

f represents a pole, secured to the frame 0 and provided with an eyebolt, g,r.ndepending from the pole and passing through a hole in the middle of the double-tree, the back face of which is provided with a staple, h, through which a chain, t, passes, the chain being socured to the eyebolts j j of the barrow-sections k near their forward ends, and its upper end attached to the eye of the bolt 9, depending from the pole.

l l are parallel supporting-rods for the seat.

The rods 1 l are secured to the upper face of the frame 0, and their horizontal parts are adapted to fit in grooves in the lower face of the seat-frame, whereby the seat may he slid back and forth to adjust the seatto the weight of the driver.

The barrow-sections 70 k are each provided with eyebolts m m, projecting from the inner faces of their inner longitudinal bars and lyin g opposite each other. Through the eyes of the bolts on a rod, n, is passed, whereby the two barrow-sections are hinged or pivotally secured to each other.

0 0 represent eyebolts secured to the outer longitudinal bars of each barrow-section, opposite each other and under the axle.

pp represent guide-rods secured in the eyes of the eyebolts 0, thence passing vertically upward through holes in the axle, and thence through holes in the upper ends of angular standards q, secured to the axle.

r r represent horizontal shafts,journaled in the standards 61 g on each side of the central longitudinal line of the machine. Each shaft r carries an eccentric, 8, near its outer end, having a grooved periphery, in which is fastened one end of a chain,t,which passes partly around the eccentric, and is secured to a harrow-section near its outer edge.

a to represent levers, each secured to the inner end of one of the shafts 1', by means of which the driver in his seat can raise or lower the outer edge of either barrow-section independently of the other to avoid obstructions, or for other purposes.

11 represents a horizontal shaft, the ends of which are reduced and have their hearings in end recesses in the shafts r 1'. The shaft o carries two eccentrics, 'w to, having grooves in their peripheries for the reception of the chains or y,secured at their upper ends in the grooves in the eccentrics w, and each chain, at its lower end, is secured to one of the narrow-sections.

2 represents a lever, secured to the horizontal shaft 'u,and extending up near the drivers seat, whereby the driver can, by operating said lever, raise or lower the inner parts of both barrow-sections at the same time.

By the above-described construction it will be seen that the outer edge of each harrowsection may be raisedor lowered indepcndentl y of the other to avoid obstructions, or that the pendent shafts r r, carrying the eccentrics s a central part of the harrow alone may be raised and levers u u, chains t, independent shaft 1 or lowered, or that both barrow-sections may carrying the eccentrics w w and lever z, and be raised or lowered bodily, to avoid ohstrucchains as y, secured to the eccentrics w and the 5 tions or in going to and returning'from the barrow-sections, substantially as described, 15

field. and for the purpose set forth.
