Description
WELCOME J. BURDIOK, OF ALFRED, NEW YORK, ASSIGNOR TO HIMSELF l UNITED STATES PATENT OEErcE.
AND JOEL F. MOURHESS.
IMPROVEMENT IN HARROWS. i
Specification forming part of `Letters Patent No. 105,775, dated July 26, 1870.
To all 'whom 'it 'may concern:
Be it known that I, WELCOME J. BURDICK, of Alfred, in the county of'Allegany and State of New York, have invented a new and useful Improvement in Rotary Harrows; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawing, and tothe letters of reference marked thereon.
In the accompanying drawing, Figure 1 is a top view of my improved rotary harrow. Fig. 2 is an elevation of the same.
My improvement in rotary harrows consists, first, in a -peculiar novel construction of hub for holding the radial arms which carry the teeth; second, in a reversible arm provided with an adjustable weight and a revolving wheel traveling on the rim or circular track of the harrow; and, third, in the use of two rollers under the beam.
In the construction of my improved rotary harrow the hub is castvin two parts, A and B,
and extends down through the lower plate, B.
The central portion of the hub projects'upward to give a bearing for the revolving draftbeam F, which is thus raised high enough to allow the teeth Gr to extend some distance above the radial arms E. By this arrangement long teeth may be used and driven down as they Wear away below.
The beam F is provided with two rollers, H and I, which travel upon the ring or rim K, thus holding the beam steady, and yet allowing a free rotary motion.
A reversible arm, L, is hinged to the beam, and provided with an adjustable weight, M, which is set by a thumb-screw, N. This arm also has a rolling weight or Wheel, O.
Having described my invention, I claim- 1. The above-described construction and arrangement of hub, the same being made in two parts connected by bolts, substantially as set forth. f
2. The reversible arm, when provided with the adjustable weight and revolving weight or wheel, substantially as set forth.
3. The two rollers I and K, in combination
