Specication of Letters Patent.
.Patented March 13, 1906.
T0 au whoml it may concern:
Be it known that I, JULIJAN CIHALEWSKI, a citizen of the United States of America, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Mills, of which the following is a s ecication.
My invention 1re ates to certain new and useful improvements in mills; and its object is to produce a device of ,this class which shall have certain advantages which will appear more fully and at large in the course of this specification.
To this end my invention consists in certain novel features which are shown in the accompanfying drawings as embodied in my preferred orm of constructionl In the aforesaid drawings, Figure 1 is a side lview of amill embodying my invention. Fig. 2 is a vertical diametrical section throu h the same. Fig; 3 is a plan vlewfof one o the mill'stones, and Fig. 4 is a vertical diametrical section taken in the line 4 4 of Fi i 3.
eferrin first to Figs. 1 and 2, A represen-ts the amework of the mill, upon the base of which is secured a bracket al, ada ted to .receive the lowerend of the driving-s aft B. A lever a is pivoted in the bracket, one arm of which su ports the lower end of the shaft, the otherb a in the bracket a y turnin the setscrew the shaft may be raised or owered to regulate the coarseness or fineness of the `round material Ti ht and loose pulleys b are mounted upon t e shaft B, by means of which the shaft may be belted to any suit- The upper end of the shaft is journa ed in a bearing c secured upon the lower face of a plate C, sup orted upon thato of the frame'A, said p ate formin A hoo rests u on the plate C and completes the casing. his hood fits tightly upon an annular flange c', extending up from the plate o ens out from the casing or the dischar e o the ground material. Ilpon the plate C 1s a framework A', which supports a hopper E, the lower end of which em ties into a feedregulating chute E', threa ed in a neck d', extending up from the hood D. Handles e without to level up theupper millstone.
earinagainst a set-screw' A spout d and is carried by set-screws ff, which extend u through the hood and are accessible frprm o furnish more delicate means for this adjustment, other set-screws f2 are 'provided 1n the hood which bear directly upon the m111- stone. The lowermillstone is mounted upon the shaft B by means of a ange g, and a nut g is threaded upon the upper' end of the shaft to clamp the millstone thereupon. The millstone G is made to fit within the flange c of the late C, so that in the vertical ad'ustment o this millstone no material is liab e to enter the space below the same.
Referring now to Figs. 3 and'4, which illustrate the preferred form of millstone'nsed in this construction, it will be seen that it consists in a flat plate G, provided with a se r1es of radially-extending blades g3 g3. A bindin -ring g4 is placed upon the plate G outsi e of the blades g2, the object of which will appear below. An annular flange g? is formed u on the plate G within the inner margin of t e blades fp, and the s ace between the ring g4 and the ange g5, an between the blades is lled in with a hard stubstance H-as, for 1nstance, stone or artificial stone, such as concrete, cement, or the like. The blades are thus embedded in the stone substance, their upper surfaces only being exposed. In practice the blades form rid es, while the surface of the stone between t e blades forms the furrows, which are necessary in devices of this kind. The inner edge of this stone material flares from the edge of the flange g5 to the 1n ner u per corners of the blades g3, so as to rovi e a hopper-like entrance to the space Yetwen the millstcnes to direct the ram t be ground toward the grinding-su aces the millstones.'
The construction.: of the upper stor practically the sam-e as the lower on only dierence being that it is arrange supported by the hood, Whereas t F is leveled up one is arranged to be su ported upon the shaft. The construction o the grinding-faces is just alike.
In preparin the millstones the space between the bla es and ring is filled npwith the stone material flush with the tops of the blades and ring; but being somewhat softer than the metal blades and ring it wears away more rapidly than the metal parts, so that after the stone has been used a very short while the blades become ridges upon the surface of the stone, whereby the effectiveness thereof is greatly facilitated. It should be noticed that the blades g3 are spaced farther apartythan vthe peri heral blades g2, thereby leaving the furrows etween them wider near the center than at the circumference. This facilitates the feed of the material through the grinding devices. -To regulate'the feed to the millstones from the hopper; lthe feed-chute E may be raised or:lower'ed,'thereby increasing or decreasing i the'openng between it and the lower millstone. The u per o stationary millstone .by allowing it to rest upon the lower millstone, then turning the setcrews f' fafter which the lower lnillstone can be lowered as much as is desired by the setserewfa. A. .Inlthe o eration of the mill the rain to be ground is um ed into the hopper 4 and runs through the eed chute into the annular space in the center of the millstones, from 35 ground, after which it falls into the casing l whence it runs out between them where it is and eventually discharges out through the spout d.
I have described the filling material as con sisting either of natural stone or artificiallymade stone, and l wish it to be understood that in the claim this refers to an hard substance whicb, however, is not as liard as the blades, so that in the operation of the device this hard substance will wear away somewhat more rapidly than the blades, so as to leave furrows and ridges in the grindingfaces of the millstones.
I realize that considerable variation is possible in the details of this construction without departing from the spirit of theinvention, and I therefore do not intend to limit myself to the specific form herein shown and described.
I claim as new and desire to secure by Letters Patentd [n a device of the class described, the cornbination with a basesplate havin an annular rib upon its upper face, of a hoo fitted upon said rib and extending up from the base-plate, .f
a stationary millstone adjustably sup orted by said hood and a rotatably-mounte millstone tting the inner edge of said rib.
In witness whereof I have signed the above application for Letters Patent, at Chicago, in the county of Cook and State of Illinois, this 21st day of January, A. D. 1905.
