ZEDEKIAH DAWSON, OF COLE CREEK, INDIANA.

IMPROVEMENT IN MILLSTONE-BALANCES.

Specification forming part of Letters Patent No. 118,113, dated August 15, 1871.

To all whom it may concern:

Be it known that I, ZEDEKIAH DAwsoN, of Cole Creek, in the county of Fountain and State of Indiana, have invented a new and Improved Millstone-Balance; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawing making a part of this specication, in which.

Figure 1 is a side elevation, and Fig. 2 is a transverse vertical section.

My invention is an improvement on the millstone-balance of G. W. Wilson, for which Letters Patent ofthe United States were issued August 31, 1869, N o. 94,370. In that case but one band is used for encircling the stone and sustaining the desired number of weights. The weights are necessarily of large size, and hence cannot be placed near the top of the stone, which is the furthest point from the point of suspension or balance of the saine. I do not claim anything shown in patent to said Wilson.

In my invention there are three bands used, joined at the ends by rivets or analogous devices, and sustain long, narrow, and thin weights. Thus all the weights used may be placed on one side of the stone, one above the other and near its top, and, being` thin, take up little space around the stone or within the curb. They are cheaply constructed and easily applied and adjusted. rI he means used for tightening the bands are notched wedges.

Referring to the drawing, a is the stone, and b b b the weights. The lower weight is composed of three or more straps, the middle one of a single piece, and the upper one of two straps, so that, if there is need, a single strap may be taken off or be added to either weight. The Weights are grooved at their ends, so as to receive and hold the bands c, whichinclose them and encircle the stone. The bands are riveted together at their ends, and wedges d are driven under them to tighten them, said wedges being transversely grooved or ridged, so as to hold them in connection with the bands. The Wedges are driven opposite the weights. By making the weights so long their thickness is diminished so that they go inside the hoop tln t incloses the stone without touching it. rIhe weights may be shifted anywhere to maintain the balance ofthe stone. The weights are at the exterior of the stone, or, in other words, at the greatest distance from the axle, and where they may be, consequently, of the most effective gravity. By reason of their length, entirely encircling the stone, they enable it to be balanced most perfectly. These Weights are, in fact, in the nature of hoops.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

In combination with a millstone, a, the weights I) b I), when constructed, applied, and arranged for operation in the manner described and shown, and for the purpose set forth.

ZED EKIAH DAWSON.
