IMPROVEMENT lN MlLLSTONE-BALANCING DEVICES.

Specification forming part of Letters Patent No. 192,454, dated June 26, 1877; application filed May 5, 1877.

To all whom it may concern:

Be it known that I, LUTHER READ, of Henderson, in the county of Jefferson and State of New York, have invented a new and useful Improvement in Millstone Balance, of which the following is a specification Figure l is a top, and Fig. 2 a side, View of a"millstone illustrating my invention, parts being broken away to show the construction.

Similar letters of reference indicate corresponding parts.

The object of the invention is to enable a millstonc to be accurately balanced, both standing and running, in a very short time.

The invention consists in the horizontal cups formed in the middle and upper parts, either or both, of each quarter of a inillstone beneath the band, and provided with a hole leading into the upper part of said cups through said band, and closed with a screw, as hereinafter fully described.

A represents a millston'e which is bound with a wide upper band, B, and a narrow lowerband, O, in the usual way. In the upper and lower parts ofeach quarter of the stone A is formed a horizontal cup, I). The lower cup D is level'with or a little below the cockcye, and the upper cup is at or near the upper edge of the band B. The cups D are made with straight bottoms and ends, and with their tops inclining upward from their ends to the center, as shown in Figs. 1 and 2. The cups D I prefer to make about nine inches long, about one and a quarter inch deep, and about one and a half inch wide or high in the widest part or center.

The cups D are covered or closed by the band B, and through said band, at the top or angle of each cup D, is formed a hole, d, which hole is closed with a screw, E.- The holes 61 should be large enough for shot to pass through them. Should too many shot be put into the cups, by turning the stone A over so as to bring the angle of the top of the cups D downward, the shot will run out through the holes 11.

In the case of old stones the lower cups D may be formed in the stone through holes cut in the band B, which holes are afterward cov-- ered by patches 1), secured to the band B by screws. In this case the upper cups D may be formed by removing a part of the plaster, putting in the shot, and replacing the plaster.

The upper cups D are designed for use for balancing the stone when it is heavy on top upon one side, and heavy on the bottom uponthe other side.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- A millstone provided with the two alternate sets of cups D upon its peripheral surface, as described, covered and inclosed by a sheetmetal band, B, having inlet-openings (1, as and for the purpose specified.

LUTHER READ.
