CHARLES'F. SHUMAKER, OF SILVER CREEK, NEVV YORK.
MACH|NE"FR GRlNDlNG GRAIN.
SPECIFICATION forming part of Letters Patent No. 265,160, dated September 26, 1882.
` Application filed April 27,1882. (No model.)
To all whom it may concern:
Be it known that I, CHARLES F. SHUMAKER., ot' Silver Creek, iu the county of Chautauqua and State of New York, have invented new and useful Improvements in Machines for Grinding Grain, ot' which the following is a specification.
The object of this invention is to reduce the grain by comminutin g the Hour-producir] g portions without pulverizing the bran; and my invention relates to improvements in that class of reducingmachines which are composed of two reciprocating plates arranged face to face with each other, and having their faces provided wilh suitable ribs or corrugations which operate upon the grain passing between said plates.
My invention consists ot the improvements in the construction of the machine, which will be hereinafter described, and pointed out in the claim.
In the accompanyingdrawings, Figure 1 is a vertical section of my improvedinachine. Fig.
2 is a top plan view thereof. Fig. 3 is a horizontal section in line as so, Fig. 1.
Like letters of reference refer to like par ts in the several figures.
A A. representthe upright side frames of the machine, and b the horizontal driving-shaft, supported in bearings B, secured to the side frames, A. The shat't bis provided with a pulley, C, which receives power from an endless belt, c, or from any other suitable mechanism, whereby it is rotated.
l) represents the feed-hopper, into which the grain to be reduced is delivered by a suitable spout, and which is provided with a feed-roller, d, and a feed-slide, d', constructed and operated in any suitable and well-known manner.
E is an inclined board or chute, which receives the material discharged by the feedroller and delivers the same between the grinding-surfaces.
F and G represent the grinding-plates, pro vided on their contiguous faces fand g with transverse ribs or corrugations to effect the reduction for which the machine is designed. These plates are arranged in an upright position, and each receives a reciprocating motion by eccen trics or cranks h, formed on or secured to the shaft b, and connected with the plates by rods h. The plate F is provided at both sides with projecting ribs z', which slide in stationary vertical guides or grooves I, formed wit-h'or secured to'the side frames, A. The plate G is provided atboth sides with similar projecting ribs,j, which slide in vertical guides or grooves J, made adjustable toward and from the plate F, so that the distance between the plates can be regulated byadjusting the ways J of the plate G. The grooves J are formed in upright bars K, which are arranged in recesses L, formed in the side frames, A.
m m are horizontal setscrews working in threaded lugs m', formed on the side frames, A, and connected with their inner endls to the bars K in such manner that by turning the set-screws in one or ,the other direction the bars K and the plate G, sliding in the grooves J of said bars, are moved toward or from the plate F, as may be desired. The plates F and Gr are itted with their sides snugly against the side frames, A, as shown in Fig. 3, to prevent the escape of any material between the edges of the plates and the frames.
N represents a casing which incloses the side plates and which is secured to the side frames, A.
u is the discharge-opening, formed at the lower end ofthe casing N, for the escape ot' the ground material.
The upper ends of the plates lF G are constructed with inclined portions o, descending toward the working-facesfg of the plates, to direct the material to be ground between said faces. The plate F is provided at its upper end with an upwardly-projecting flange, p, to prevent the material escapingfrom the inclined board E, and striking the upper edge of the plate F, from passing over said edge. The grain or other material to be ground falls from the feed-hopper in streams of uniform thickness upon the inclined board E, which latter conducts the material between the workingfaces f g of the plates F G. The material passes downward between the working-faces of the plates F G by gravity and with a rolling movement, and is reduced to the desired degree of neness during its descent between said working-faces, according to the size of the space between the working-faces and the size of the ribs or corrugations on the same. The
IOO
ground material escapes through the dischargeopening n, and may be conducted to a bolt or sieve, whereby the coarse offal is separated Afrom the ner or valuable portions in a wellknown manner. A number of these machines with gradually-increasing fineness ot' ribs or corrugations may successively operate upon the material until it has been reduced to the desired degree of neness, and a separation of the coarse from the fine particles of the Ieduced material may be eft'ected between every two reductions in a well-known manner.
The space between the working-faces fg of the plates may gradually decrease from the top toward the bottom to facilitate the entrance ot" the material between the plates audits passage through the space between their workingfaces. l
Itis obvious that only one plate may receiy'e a reciprocating motion and the other plate vremain stationary, and in that case the adjustable plate should be made stationary; bu-t I prefer to have both plates actuated, as such a construction produces better results. It is also obvious that the plates may be slightly inclined, provided the passage of the material throughthe space between the plates is notprevented thereby.
I claim as my invention.-
In a machine for reducing grain and other like material, the combination, with two npright plates, F G, having their adjacent faces provided with suitable ribs or corrugations, and suitable mechanism whereby a reciprocating motion is imparted to both plates, of grooved guides or ways I, in which theplate F slides, grooved bars K, in which the plate G slides, suitable mechanism whereby the bars K can be adjusted toward and from the plate F, and means whereby the material to be reduced is introduced between the upper ends ot' the plates F and G, substantially as set forth.
