HARROW.

SPECIFICATION forming part of Letters Patent No. 470,401, dated March 8, 1892. Application filed April 1l, 1891. Serial No. 388,531. (No model.)

To all whom it may concern:

Be it known that I, JAMES H. RICHMOND,

a citizen of the United States, residing at Ardeola, in the county of Stoddard and State of Missouri, have invented a new and useful Harrow, of which the following is a specification.

This invention relates to improvements in harrows, and has for its obj ect the construction of a cheap and simple harrow adapted to thoroughly pu'lverize and harrow the soil and to be thrown into and out of operative position forthe purpose of transporting the machine to and from the scene of operation.

Other objects and advantages of the invention will hereinafter appear, and the novel features thereof will be particularly pointed out in the claim.

Referring to the drawings, Figure 1 is a perspective of aharrow constructed in accordance with my invention. Fig. 2 is a vertical longitudinal seotiomthe harrow being folded Fig. 3 is a transverse section of Fig. 1.

Like numerals of reference indicate like parts in all the figures of the drawings.

1 designates an axle, preferably rectangular in cross-section and reduced at its extremities to form bearings 2 for the reception of a pair of ground-wheels 3. From the front of the axle extends a draft-tongue 4E. Perforated ears 5 extend rearwardly from the axle near the bearing ends of lthe same, which ears are pivoted, as at 7, to the forward bifurcated ends of front sectional side bars (i, the rear ends of which are loosely hinged, as at 6, to the forward ends of rear sectional side bars 6b, the rear ends of which are connected by the harrow or drag-bar 8, transversely disposed. The drag-bar is provided with a series of perforations, through which' pass rigid barrow-teeth 9. The under sides of the sections 6 are provided with bearings 10, and in the bearings is mounted for rotation atransverse shaft 11, provided at intervals with harrow-disks l2, so located upon the shaft as to alternate with 4the teeth 9 of the drag-bar. A seat-standard 13 extends rearwardly from the draft-tongue 4 and supports a drivers seat 14. At one side of the seat-standard there is mounted upon the axle a short vertical post or standard 15,in which is loosely mounted a pulley 1G, while at the opposite sideof the standard there rises from the axle a standard 17, to which, as at 18, is pivoted a hand-lever 19. This lever is provided with a locking bolt or ratchet 19a, designed to engage with a toothed locking-sector 20, located upon the axle. To `the lower end of the lever 19 there is secured a chain 21, which chain is passed forward through a pulley-block 23, located upon the tongue 4C, and rearwardly over the pulley 16 to the rear end of the frame, where it terminates in a hook 24 forremovaloly engaging a staple 22 upon the drag-bar.

In operation the disks cut the soil, while the teeth following thereafter pulverize the same, as will readily be understood. All trash collected by the harrow-teeth may be readily dropped at convenient spots by simply raising the drag-bar through the medium of the lever and chain. When it is desired to travel from one iield to another or to and from the point of use, the drag-bar is thrown over upon the sectional side bars Gl, which may be accomplished by ireason of said sectional side bars being hinged to the rear sectional side bars 6b, and the hook 24; having been disengaged from the staple 22 of the drag-bar the chain is passed around the dragbar under the same and connected to the shaft lO. Now by operating the lever 19 the rear frame-work is raised upon the pivots 7 until the disks are abovethe ground, and the apparatus may be transported upon the wheels 3.

Having described my invention, what I claim isw- The combination, with the axle having ground-wheels, rearwardly-disposed perforated lugs, and a forwardly-disposed tongue,

of front sectional side bars pivoted to tlie` lugs and having bearings@ shaft mounted in the bearings, harrow-disks mounted on the shaft, rear sectional side bars hinged to the rear endsof the front sectional bar, a transverse drag-bar connecting the rear ends of the rear sectional loars, harrow-teeth mounted in the drag-bar, a staple mounted upon the dragbar, a lever fulcrnmed upon the axle and having a locking-bolt, a sector for engaging the IOO bolt, a pulley-block located upon the draftloar, a standard and vits pulley located upon the axle in rear of the pulley-block, and a chain connected to the lever, passed through 5 the pulley-block and over the pulley, and terminating at its rear end in a hook for removably engaging the staple of the dwg-har,L

whereby said chain may be passed over the drag-bar and engage the disk-supporting shaft
