COMBINED HA RROW AND CLOD-CRUSHER.

SPECIFICATION forming part of Letters Patent No. 285,644, dated September 25, 1883.

' Application filed 3, 1883. (bio model.)

To all whom/it may concern Be it known that I, SAMUEL MILLER, a citizen of the United States, residing at Moweaqua, in the county of Shelby and State of Illinois, have invented a new and useful Improvement in'Combined Harrows and Olod- Crushers, of which thefollowing is a specification.

This invention is designed as an improve: ment upon Patent No. 188,379, issued to WV. H. Kuhn and myself. I have found that in use the sections marked D in said patent, made as therein described, oblong rectangular planks, will very quickly warp, owing to the double action of the sun above and the dampness of freshly-turned earth below, thus binding on the pivot-rod E and avoiding their purpose by preventing them from swinging on the rod, and that the same action frequently cheeks said planks and allows the teeth to fall out; and the object of the present invention is to overcome these objections and to provide a better way of fastening part of the harrowteeth; to which end it consists in the construction and combination of parts hereinafter described and claimed, reference being had to the accompanying drawings, in which Figure l is a longitudinal sectional elevation of my combined harrow and clod-crusher. Fig. 2 is a plan view of the same. Fig. 3 is a top View of one of my harrow-frames in detail, and Fig. 4 is a rear end view of the same.

A represents the frame of the harrow, of rectangular form, bolted together at the corners, so that the beams may be separated and closely packed for transportation.

D represents a system of frames, all hung to swing vertically on one common rod, E. Each of these frames consists of two parallel bars, 6, hung upon rod E, a diagonal or brace bar, f, and a eross bar, g, all rigidly secured together. The grain of the wood of cross bar 9 runs in a direction at right angles to the sides 6. To the under side of this crossmore straps, h, and screw-bolts 2'. These teeth lean forward at an angle of about forty-five degrees, and each tooth is bent to form the upper part into a shank, to rest against the under side or in grooves in the under side of the crossbar g. The straps h are placed below these shanks and bound by bolts '5 up to the cross-bar, rigidly holding said teeth. By this means fewer holes are made in the cross-bar, and the teeth may be readily removed for sharpening. They may also) be twisted to stand leaning sidewise by partly rotating the shank, thus causing the earth to turn to or fronrplants, as may be desired. In the diagonal bar f, I place otherteeth, c, leaning forward only a little. Each section being hung independently of the others, when a clod is caught under any one section, it raises the main frame and thedriver occupying seat 13. The united weight supported on said raised section tends to crush the clod under it. In case straw, grass, or other obstructions get caught in the teeth, each section, be ing made up of timbers, is open, permitting easy access directly to the obstruction to remove the same by pressing it down with a stick while the harrow .drags over it. While the main weight of the frame will be supported by any one of the sections which rises above the others, they will, each by its own weight, swing down and continue to work 111 the ground. Individual sections may be removed to adapt the harrow tocultivate between rows of low corn, &c.

The harrow will be provided with any usual means for attaching-a team, such as the chain 0; and the drivers seat B may be attached in any usual manner to the main frame A.

I am aware that a harrow made in sections somewhat similar to mine is the subject of Patent No. 201,435, and I do not claim the same as my invention.

What I claim as my invention isl. The combination, with tl1e 'mai11 frame A, provided with a cross-rod, E, of a series I of frames, D, consisting of the side bars, 6, hung upon rod E, the diagonal bar f, and the cross-bar g, firmly secured to sidefbars, 0, said frames D hanging independently upon rod E, and teeth 0 and d, fixed to said frames D, as and for the purpose specified.

2. The combination, with a harrow-frame having longitudinal grooves in its under side, as an axis, and fixed at different angles of of bent barrow-teeth having shanks adapted right or left inclination from a longitudinal 10 to rest in said grooves at any angle, and vertical plane. bodies hanging to the rear from said shanks,

a strap to rest against the under sides of said shanks, and bolts passing'throngh the strap \Vitnesses: and frame, as described, whereby the body A. J. STEIDLEY, of the tooth may be rotated upon its shank J. O. MILLER S AMUEL MILLER.
