' H.-SHAW. I GRINDING MILL.
No. 93,913. Patented M917, 1869.
Letters Patent No 93,913, dated Auoust 17, 1869.
M IMPRO'V'EMIIENlI IN GRINDINQMILL S. w
The Schedule referred to in these Letters Patent and making pan. of the same.
To all whom it may co-rwern Be it known that I, HENRY SHAW, of Cincinnati,
in the county of Hamilton, and State of Ohio, ha.ve
invented a certain new and useful Improvement in Iron "Grinding-Mills; and I do hereby-declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings, making part of this specification, in which 7,
Figure 1 is a perspective view of a section of a, grinding-plate, A, and supporting or back -plate, B, both being placed in position to show their interioi' surfaces.
Figure 2 is a section of platesA and B, joined together in the usual manner.
The object of my invention is an iron grinding-mill, the grinding-surlhces of which shall remain cool during the operation of grinding, at the same time dis; pensing with the intermediate layer of non-conducting substance, described and claimed in the Letters Patent granted Henry Shaw and William D. Leavitt, on the 14th day of July, 1868.
My means for accomplishing the above purpose is an air-chamber formed between the grinding-plates,
respectively, and, the back or supporting-plates.
Projections G and O are formed upon the interior surfaces of the grinding and back-platcs, as clearly -shown in the drawings.
The plates are circular in form, the projections also are circular, and the plates, grinding and backeplates, are rigidly attached to each other, so that none of the material ground or to be ground, may pass into the air-chamber. The well-known low conducting-power of air makes it an efiicient agent for the above-described pnrpose.
Haring. thus described my invention,
What I claim as new, and desire to secure by Letters Patent, is-
An iron grinding-mill, having the projections O and 0' between the grinding and back-plates, for'the-purpose described. I
HENRY SHAW. Witnesses:
S. S. MORRIS, THEO. ALBERT.
