IMPROVEMENT IN HARROWS.
Specieation forming part of Letters Patent No. 151,505, dated June 2, 1874; application filed December 27, 1873.
To all whom t may concern:
Be it known that I, OBADIAH G. NEWTON, of Grundy county, in the State of Missouri, have invented new and useful Improvements in Harrows for Agricultural Purposes, of which the following is an exact and clear specification, reference being 'had to the accompanying drawings and to the igures and letters of reference thereon, which are made parts of this specification.
Figure l is a top view. Fig. 2 is a longitudinal section. Fig. 3 is an end view. Fig. 4 shows one of the details.
This barrow has two rollers in asquare frame, braced angnlarly. The dra-ft is ap- The frame a a is further strengthened by the front cross-piece b and the timbers c c above the teeth, these timbers serving also as fenders or guards. The rollers d d revolve on journals let into the sides ot' the'frame, and are provided with double-length teeth e e. These teeth are to be made square and pointed, as barrow-teeth usually are. A lever, f, with handle, is afrixed to the side of the frame and the center of the angular brace g, which operates the scrapers h It and stead yin g-frames fz'. l1T. A separate lever can be applied for each scraper, whenever thought desirable. The scrapers h h are hinged to the brace supporting the timbers 0 c, and the rods passing through the ends of these scrapers should be provided with a screw and nut, so that each scraper may b e raised or lowered at will. The front pieces of the steadying-frame should also be set on with screws, so that they may be moved as the teeth wear short. I also provide my barrow with false shoes 7.' k, or runners. Small hooks l l, Fig. 4, are also fixed to each scraper.l The hook is to catch one of the teeth of each roller and hold it stationary, while the false shoe is placed on the lower row ot' teeth, as shown in Fig. 3. into a sled, can, by hitching to the center of the frame, at a point opposite the lever, be now drawn to or from the field without danger of bending or injuring the teeth from contact with stones, stumps, or other obstructions. fhen at work the runners or false shoes are taken oft the teeth and placed on the pins on The liarrow, being thus turnedy the timbers c c, as shown in Fig. 1. The drafthook m is applied at the corner of the frame of the barrow, which is, therefore, drawn crosswise, giving as much pressure endwise on the tooth-shaft as sidewise. While in motion the upper teeth will rest on the front piece of the steadying-frame and hold the lower teeth to the ground; but if the lever be pulled forward the shaft will revolve until the lower teeth are brought into contact with the scraper, which is then used, by a simple motion of the lever, to clear the teeth from all grass, weeds, or trash that may have adhered to them. rlhe scrapers may be made of iron, or of wood and ironed on the bottom.
By removing the draft-hook from the corner of the frame and attaching it to the side, near the end of the angular brace, (at a, Fig. 1,) the barrow may be drawn so as to pass over rows of young corn without injury, and thus serve as a eultivator or plow.
The mode of operation is so simple that further description seems to be unnecessary. The advantages of my invention will readily present themselves to all who use agricultural implements.
I claim as ot' my invention and desire to seo cure by Letters Patent l. The scrapers and steadying-frames, operated by a lever affixed to the side of the frame and the center of the angular brace, in combination with the revolving shafts, as described and shown, and for the purposes set forth.
2. The false shoes or runners, in combina- OBADIAH Gr. NEVTON.
