JOSEPH H. GLOVER, OF SKEGGS CREEK, KENTUCKY.

BALANCE-IRON FOR MILLSTONES.

Specification of Letters Patent No. 18,74L1, dated December 1, 1857.

To all whom it may concern:

Be it known that I, JOSEPH H. GLOVER, of Skeggs Creek, in the county of Barren and State of Kentucky, have invented a new and useful Improvement in Bails or Balance-Irons for Millstones; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawings, making a part of this specification, in which- Figures 1 and 2, are vertical sections of my improvement, the planes of section intersecting each other at right angles. Fig. 3 is a detached view of the adjustable block.

Similar letters of reference indicate corresponding parts in the several figures.

This improvement consists in having an adjustable block arranged within the bail as and for the purposes hereinafter set forth.

To enable others skilled in the art to fully understand and construct my invention, I will proceed to describe it.

The bail or balance iron is formed of two legs (a) (a) connected at their upper ends by a cross-bar or portion (1)) which has side-plates (0) attached to form a box A, as shown in Figs. 1 and 2. The legs (a) (a) and cross-bar (b) may all be formed of one bar of iron. The lower ends of the legs (a) (a) are bent outward horizontally a short distance, as shown at (5 (6 Fig. 1, and the upper surfaces of said projections are rounded and fitted in recesses made in the stone at the edge of its eye, see Fig. 1, in which the stone is shown in red. By having the projections (Z3 (5 formed with rounded upper surfaces, the stone will rest or bear on the center of the projections, which, provided the curves are regular, are in the same plane as the spindle, shown in red. Within the box A, a steel or metallic block B, is fitted or placed. This block is somewhat smaller than the interior of the box, and a groove (0) is made horizontally around it. Through each side of the box A, a set screw (d) passes; and the inner ends or points of these screws fit in the groove and retain the block B in its proper place. The under surface of the block B has a center hole (6) made in it, to receive the point of the spindle. It will be seen that by adjusting the block B laterally by means of the set screws (cl), the stone may always be kept in a perfectly balanced state, without any trouble or expense; and when the center hole (0) becomes worn by use, the block B may be removed and a new one inserted in its place.

The ordinary bail, it will be understood is permanently secured within the eye of the stone, and when a new center hole is required, the bail is detached from the stone at considerable expense. The stone also is now balanced by adding weights to it, at the light side. This plan is an imperfect one, and is attended with considerable trouble.

I am aware that the bails of mill-stones have been provided with blocks which were interposed between the point of the millspindle and the interior surface of the bail; but to the best of my knowledge and belief, it is new to render such blocks adjustable by means of screws, whereby the stone may at all times be readily balanced and a bet ter operation of the parts be thus secured, and the quality of the flour improved.

In the patent of 'E. It. Benton, March 31st, 184cO, a block is interposed between the point of the spindle and the bail; I disclaim everything contained in the patent of said Benton which resembles my improvement.

What I claim as my invention, and desire to secure by Letters-Patent, is

The block B, when made adjustable from the exterior of the bail by means of screws (d), as and for the purposes herein set forth. 1
