GRINDING APPARATUS- SPECIFICATION forming part of Letters Patent N0. 776,973, dated December 6, 1904.
Application filed December 14:, 1900. $erial No. 39,904. (in; model.)
To all whmn it may concern:
Be it known that I, ROBERT L. WATSON, a
' resident of Memphis, in the county of Shelby and State of Tennessee, have invented certain new and useful Improvements in Grinding Apparatus; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
My invention relates to an improvement in grinding apparatus, and more particularly to an apparatus for grinding cotton-seed hulls and cotton-seed products, the object of the invention being to provide an apparatus of this character which can be readily adjusted to grind the material into different degrees of fineness.
With this object in view the invention consists in certain novel features of construction and combinations and arrangements of parts, as will be more fully hereinafter described, and pointed out in the claim.
In the accompanying drawings, Figure 1 is an end View illustrating my improvements. Fig. 2 is a side elevation, and Fig. 3 is a view in section of the same.
1 represents a supporting-frame which comprises at each side an inverted-V-shaped standard 2, the respective members thereof connected by horizontal bars 3 and said standards connected by braces, as shown. To the lower end of one member of each standard uprights 4 are secured, and suitable bearings 5 are provided at the upper ends of standards 2, in which is mounted a shaft 6, carrying at one end a driving-pulley 7, and has secured thereon between the standards a cylinder or grinding roller 12, provided with a coating of emery or other like material. A concave 8 is disposed around one-half of the roller, and its inner face is curved in practically the same are of a circle as the cylinder and provided with a covering or coating of emery or like material.
Plates 9 are secured to the respective side edges of the concave 8 by means of rods 10 and are adapted to overlap the ends of the roller 12 to prevent the escape of material be ing ground, and the lower ends of said plates are pivotally connected to the opposite bars 3, as shown.
A suitable hopper 15 communicates with the upper face of the roller for feeding material to be ground thereto, the ground material being discharged at the lower end of the eoncave.
Various slight changes might be resorted to in the general form and arrangement of the several parts described without departing from the spirit and scope of my invention, and hence I would have it understood that I do not wish to limit myself to the precise details set forth, but consider myself at liberty to make such slight changes and alterations as fairly fall within the spirit and scope of my invention.
Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-
In a grinding-machine, the combination with two standards spaced apart, an upright adjacent to each standard and projecting above the same, and a cross-bar mounted at its ends upon the uprights, of adrum or roller mounted between the standards and having an abrading periphery, a semicircular concave at one side of the drum or roller and having a continuous abrading-face adjacent to the roller and extending from a point directly over the axis of the roller to a point directly under said axis, curved plates disposed against the ends of the concave, bolts connecting said curved plates, pivots connecting the lower ends of said plates to the standards under the axis of the drum or roller, threaded rods piv- In testimony whereof I have signed this otally attached to the upper ends of said plates specification in the presence of two subscriband passing through the standards, nuts on ing Witnesses.
said rods, and a hopper disposed on the cross- ROBERT L. WATSON. 5 bar on the uprights and disposed to discharge Vitnesses:
onto the top of the drum or roller adjacent to B. F. BOOTH,
the upper end of the concave. l P. H. PHELAN, Jr.
