IMPROVEMENTiIN MIDDLINGS DRESSERS OR PURIFIERS.
Specification forming part of Letters Patent No. 133,898ydatcd December 10, 1872.
To all whom it may concern Be it known that I, GEORGE T. SMITH, of Minneapolis, county of Hennepin, State ofMixr nesota, have invented certain new and useful Improvements in Machine for Dressing Flour, of which the-following is a full, clear, and exact description, reteren ce being had to the ac-` companying drawing making part of this specification, in which- Figure lis a plan or top View of my machine with a portion of the air-Hue removed; Fig. 2 is a vertical transverse section, and Fig. is a vertical longitudinal section.
In the drawing, A represents a hopper, in which the linea] or middlings to be treatedris delivered from an elevation or by any other means. The meal is fed by the rollers Btc the bolt, the amount of feed being regulated by a slide, c. The bolt or shaker is suspended from the frame-work by pivoted links o i',
and has a reciprocatingmotion imparted to it Y by eccentric It on shaft R and the inclosingbox I. As the meal is agitated by the motion of the bolt the flour or middlings falls through it. As there is a continuous current of air in an upward direction through the bolt it will canse the very tine portions of iiour to adhere t0 the threads of which the cloth is composed,
and thus close up the meshes to such an eX- tent as to materially interfere with the operation of them. In order to obviate the adhering ot' the ne particles of Hour to the bolt I employ brushes to traverse the under side of the shaker and keep it clean. A H H are brushes attached to and carried by endless belts h, the brushes being supported on Ways kk during their contact with the bolt.
By preference I make the frame-Work and Ways which support the brushes adjustable by means of set-screws k, (see Fig. 2,) so that I can keep the brushes always in contact with the bolt.
I do not claim the application of brushes to the under surface of the bolt, as that is admitted to be old; but t Vhat I do claimin this application is- The brushes H H, when attached to au endless belt, chain, rope, or an equivalent of the same, and traveling in one direction ou ways and around pulleys, as shown, in combination with a reciprocating-bolt, substantially as set forth.
Y GEORGE T. SMITH.
