PORTABLE GRINDINGHVHLL.
SPECIFICATION forming part of Letters Patent No. 301,020, dated June 2a, 1884. Application filed November 27, 1883. (No model.)
To @ZZ whom t may concern.-
Be it known that we, REINHOLD WAAK and CARL Jamison, subjects of the'Emperor of Germany, residing at Chicago, in the county 0f Cook and State of Illinois, have invented certain new and useful Improvements in .Portable Grinding-Mills, of which. the following is a specification, reference being had therein to the accompanying drawings.
Our invention relates to an improved grinding-mill; and the object it has in viewis principally to improve the means employed for adapting-it for use with different sizes of grain, and to reduce such grain to different degrees of fineness.
The invention consists of novel devices and combinations of devices, as will be described and claimed.
Reference is made to the accompanying drawings, in which Figure l is a side view of the mill complete; Fig. 2, a vertical central section of the same, and Fig. 3 a plan with parts removed.
Like letters refer to like parts in each view.
A represents the base ofthe mill, upon vwhich are mounted the parts which inclose the feed and grinding rolls. The inclosing-casing is formed of two parts-viz., a cylindrical rollcasing, B, and a receiving-hopper, B', securely bolted together, asshown. Casing B is provided on one side, at its base, with extensions o, connected by cross-pieces b b', which rest upon the base A. Through the center of these cross-pieces b b, and through base A,are passed bolts c, screw threaded on their upper ends, where they are provided with nuts d, and at their lower ends are secured to a yoke, e. Yoke c is provided with an upwardly-project. ing lug, which presses against the under side of base A, and when the nuts cl of bolts c are screwed down tight this lug presses against said base andserves to hold easing B and hopper B iirmly in position. Elongated slots are formed through base A. for the passage therethrough of bolts c, the object of which will be explained. Formed at or about the center of eross-piece b, is a bracket, g, in which is mounted a shaft, h, provided at its outer end with a hand-wheel, t', and at its inner end with a crank-arm, j, to the pin of which is attached a rod, 7.1, which is attached at each end to the pin of a crank-arm, Z, which are secured to feedscrews m, each mounted and turning in suitable internally screwthreaded bearings, m vm", on the sides of casing B, and the boxes supporting the shaft of the grinding-roll D; The shaft of this grindingroll passes through elongated slots made in the ends of the casing, and has end bearings jin the boxes EE, secured to the base-frame.
By the arrangement of parts thus far described, it will be understood that by loosening the nuts d of the bolts c, and by turning l the hand-wheel t, motion will be imparted to I thecrankconnections and transmitted to the feed -screws, which will move the casing B and its hopper backward or forward, the movement of the casing independently of' the grinding-roll being permitted bythe slots in the ends of said casing. The casing B is provided with a discharge -spout, C, which passes through an opening in base A, and upon one side of the inner surface of vsaid easing are formed the grinding-teeth a, which form one of the grinding-surlftces in connection with the grinding-roll D. It will also be un derstood that by moving the partB backward or forward the teeth formed on theinterior of said casing are carried to or from roll D, and the space left between the two grindingsurfaces thus diminished y roll D, and also the one F, to be referred to, are preferably made of steel, and the grinding-teeth with which they are provided are formed like rasp-teeth. The journals of the upper roll, F, which is situated within the feed-hopper B', have bearings in the sides of said hopper, and at one end project out sufciently to accommodate a pulley, C, which is connected by cross-belting H with a pulley, G, D, whereby when power is applied to the roll D by means of hand-wheel I or pulley .I the upper roll is .revolved in the opposite direction to roll D. 'I'linged to the inner surface of hopper B is a strip, K, which extends down to within a short distance of roll D, and acts as a guide to direct the grain between the teeth of said roll and those formed onl the inside of casing B. To strip K is secured a or increased.4 The secured to the journal of the roll IOO screw which projects out through the side ol' the hopper, and is provided on its outer end with a hand-wheel, L. Secured to said screw, intermediate one side of the hopper B and strip K, is a sleeve, o, which adj oins said strip and at all times affords it a rest, the sleeve being fixed tothe screw to have simultaneous movement with the strip K. It will be seen that by turning the hand-wheel L the strip K is carried toward or Withdrawn from the roll F, and the space through which the grain is to pass thus diminished in size-or enlarged.
The operation will be readily understood by those skilled in the art to which the invention pertains.
Vhat We claim isl. In a grinding-mill, an adjustable casing and feed-hopper, the former provided on its inner surface with atoothed section, in combination With feed and grinding rolls, and means for revolving said rollsfor regulating the feed and for adjusting. the casing with respect to the/ grinding-roll, as and for the purpose described. p
2. rlhe casing B, )rovided with toothed section n, and hopper B', provided With plate K, in combination with rolls DF, means for ad: justing casing B with respect to roll D, means for adjusting plate K with respect to roll F, and means for revolving said rolls, as described and shown.
3. The casing B, provided With toothed section n, in combination with bracket g., hand- Wheel i, shaft 7L, rod 7c, cranks lj, screws m, and suitable bearings on the casing and roller boxes, as and for the purpose set forth.
In testimony whereof We affix our signatures in presence oi' two Witnesses.
