' .an n'cat'ioamea r br'i ar rz, 1908. Serial No. 416,379.
To it may Be it known that I, WILLIAM F LGUL-IN, a.
citizen of the United States, and -'-a resident 2s I object to provide a grinding mill so arranged as to facilitate the keeping of the same in good condition, and the making of repairs of.Portland, in the county ofMultnomah and State of Oregon, have invented a new and useful Improvement in Grinding-Mills,
of which the following is a specification,
reference being had to the accompan ing drawings as constituting apart thereo This invention has for its object to obtain a practical, durable and inexpensively const-r ucted grinding mill, serviceable for grind ing grains, cofifee,'spices, shells, and in'fact' any 1nater1al of a similar nature to be reduced to a pulverized cond1t1on. To this end my mill is. so arranged as to graduallyreduce the material ground, in one operation or process of grinding, from a coarse state to as fine a state of comminution as desired; and the grinding devices of my mill are provided with removable grinding faces, so that the grinding faces may be removed and substituted by others of a coarser or finer grade as desired.
Furthermore, my lnvention has forits as required; my mill being so arranged as to enable the removal and replacement of parts,
'or sections of parts as worn. And my mill embodies, besides, theseveral features hereinafter fully described and illustrated the drawings above referred to.
In the drawin Figurev 1 is a longitudinal vertical section, taken approximately. on
4 a line indicated by-the vertical arrow w-m shown in Fig. 2, and looking in "the-- direction' pointed by thehorizontal arrow; Fig.

Then pen;oas+j1 ing-section a is made. with an in etbpena ing J, in which to insert a hopper e; and'the lowercasing-section a ismade with-,afdigfl charge opening f, i i-"which is inserted a spout f'r The casing-section a is made with integral lateral projections g, g, con s titut ing, '60,,- the, lower part ofboxes, and to whichgarel, s secured removable caps g, constituting; he upper parts'of ,saidboxes, and iniwhic boxes, or journal'bearings, ,isL-journaled transverse shaft h, keyed in place," Theic g are secured in place by screws 9 sh only in-Fig. 15 The aperture g? Isa journal bearings constitutes oil holes, and p constitutesf-oil-weHs. On the shaft It are .rigidly. mounted a. balance wheel Land 'a70. -pulley j, as shown in Fig.'2; Thejjoui'nal," bearings for the shaft Mare 1 made jpf rsuiifi cientlylarger circumference toj ins'ei-tjhabbittvk, as usual; and; to restraintheshaft'f/t against longitudinalmovement, I' make the same; with circumferential grooves Z, into. I, whichja' ribjiof the babbitt enters,'as' illu's- 'tratedinF-ig.2. Within the casin I a there is-lri'g'idly mounted, on the sha t h,'a cylinder mf'the 801' i circumferentialeface of which is made with perforations to receive screws m, m', -by -which to secure, on .said circumferential-f face, grindin -segments n, n','each 'coverin one-fourth o said circumferential face,an the outer faces of which segments are made with corrugationsof the degree of finenesssuitable'to the particular character of the-f worlg to be done. This construction enables f irlenot only to replacesuchof thegrinding segments 01, n as maybe injured or worn, but also to substitute for the" same others off-"' coarser or finergrade, as may-be required to h work. n h d? 1 rs f ri t m 'i h' ee 0 the-6am" g agamstthennde'r side bi 30 of the-concave t areiremovably aflixed, by-

set-wheel Thus,- by the adjustment of lengthened and shortened and thereby .the space between the opposed grinding faces of thecylinder. m and the concave 23 may be increased anddiminished -as required. f
To the interior concaved or grinding face screws v concaved' shoe-segments t the outerongrinding faces of whichare suitably corrugated, coarse or fine as required, to cooperate ivith the grinding-segments n, 'n of the cylinder-m. The concave is reinforced at t to provide :a-stronger bearing for the screws -41, and has a web' If extending along the back; Different sets of grinding faces,
40 coarse ;and;fine, should alsobe provided for' theconcave t,-from-which to make a selection and adapt my-mill, to theparticular grade-of worl; on hand. 1 I
' To vkeep thematerial being ground from passing out through the side spaces, between the opposed grinding faces, the concave t is made-with integral side-flanges t arranged to inclose the lateral-faces of the grinding segments n, n, 'onjthe periphery ofthe cyl- '50 inder m.v Atthe upper end of the concave t said flanges t widen intofianges t*, so as to inclose the discharge-end 'or spout of the hopper e,-as more readily seen in Fig. 1, To
keep the grinding faces of the segments n, n afiixedtto :thecylinder m clean, I provide a brush"w,fastened to a plate -'w., 'QDCl-fidJllSlI-w ably supported by set-screws, 10 of brackets 'w fastened=-to thei'nner sidesof the case a,

The outer end of the rod u is also threaded: and thereon is placed a hand "merely f rced farther-apart"for'th'e time, to
allow such hard substance'to pass through. The bearing of the grinding faces is adjusted by the set-wheelsp", u 4 To remove the-concave, for the purpose of 7 renewing or replacing its grinding'segments, it is only necessary to release the spring 8 and remove the pm if, through a hole. a. An opening a is also provided to facilitate the adjustment of the nut-collar u 1 Though I have described the;.peripheral grinding face of my. mill as made of seg ments, and this is no doubt the'more prac-' tical way-of making, the same, I am not to p ;be underftood as limiting myself to such con- A one-piece ring-like grinding face c'ould be removably fastened to the pe riphery of my cylinder, and this featureis an unimportant element in'the other 'combinations of-my mill.
I claim: 1. In a grinding mill, the combination of case, a cylinder rotatably mounted thereq in, a concave, a threaded post, a box support- "journaled in the case and extending through theslotted sides of the box,'a cam fast on 9 ing against the under face of thelower end of the concave, andspringscontrolledmeans whereby to adjust the upper end of said concave toward and from the rotating cylinder. 2.
