R. COCHRA'N.
Grist Mill.
Patented Aug. 7, 1855.
UNITED STATES PATENT OFFICE.
ROBERT COCHRAN, OF CINCINNATI, OHIO.
METHOD OF HANGING MILLSTONES.
Specification of Letters Patent No. 13,384, dated August 7, 1855.
To all whom it may concern:
Be it known that 1, ROBERT OooHRAN, of Cincinnati, Hamilton county, Ohio, have invented a new and useful Improvement in Self-Tramming Grist-Mills; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the annexed drawings, made part of and lettered to correspond with this specification.
The nature of my invention consists in the arrangement by which I enable a grist mill to true itself if on being put in motion, it is not true and to keep itself true so long as it is in motion. There is no wabbling nor shifting, once the true center is self obtained, the parts keeping their true position as fixedly as if the whole was one solid mass.
Figure 1 of the accompanying drawings is a sectional elevation throughout the entire mill with the exception of a portion of the spindle, and shows the various improved parts. Fig. 2 represents a top and separate view of the cross timber used for supporting the bridge-plate. Fig. 3 represents a transverse sectional view of the balance-sine, cock-head, and spindle through its top. Fig. at is a horizontal sectional view of the balance-sine above the end of the spindle. Fig. 5 is an end elevation of the spindle, drawn separate, with a sectional view through the top, showing the recess in which the cock-eye is placed.
Similar letters and figures of reference, refer to corresponding parts.
A, A, represent the general frame work of a portable mill.
B, B, is the top-stone made stationary in the frame pieces (71) which can be taken off at any time for the purpose of dressing the stone.
C, O, represent the running and lower stone provided with an oblong box (5, 5,) which serves as the balance-sine, and in the center and top of which the cockhead (4c) is fitted and projects down and rests on the cock eye (2) in the top of the spindle, the cock eye being movable in the recess (3, 3,) which recess is in the top of said spindle.
(1) represents the top of the spindle (D D) made of an oblong form to suit the shape of the balance-sine. This form is adopted in order to prevent the spindle from binding whether true or untrue, leaving it thus free to attain and keep the axis of motion.
(6, 6,) is driving pulleys.
(k, 70,) is a cross piece in which the upper part of the spindle works, the piece being level with the cross pieces (J J) on which the bottom (R, R,) of the stone-case, rests. Two holes in the top of the balancesine receive and carry the damsel (6).
(11, 11, and 12,) as seen in Fig. 2 are keys fixing the cross timbers (m, m.)
(7 7,) is the bridge-plate adjusted to a hole in (m, m,) by keys (9, 9, 10, 10.) The step (8) works up and down through the bridge-plate and this hole; and is raised or lowered by the adjustable bridgetree (f, f,) by means of the screw (g, 9,) wheel (h), screw-nut 13 and boxes (14) and (15) or any other equivalent devices.
The posit-ions of the cock-eye and cockhead may be reversed but as such arrangement diminishes the practical value, it is left without further remark.
Having thus fully described and represented my invention what I claim as new and desire to secure by Letters Patent is The movable cock-eye (2) placed in the recess (3, 3) on the top of the spindle, to cooperate with the cock-head (4) fit in the balance-sine (5, 5,) or their reverse; or their mechanical equivalents, the whole being substantially as described and for the purpose set forth.
ROBERT COOHRAN. l/Vitnesses:
JAMES BIRNEY, MARTIN BENSON.
