' MACHINE FOR REDUCING GRAIN TO FLOUR AND MI DDLINGS.
SPECIFICATION forming part of Letters Patent No. 268,729, dated December 5,
Application filed August 10, 1882. (No model.)
To all whom it may concern g Be it known that I, GHARLEs S. RIDER, a
' citizen of the United States, residing at Ganton, in the county of Stark and State of Ohio, have invented certain new and useful Improveinentsin Machines for Reducing Grain to Flour and Middlings, of which the following is a specification, reference being had therein to the accompanyingdrawings.
Figure l is a side elevation of a grindingmachine embodying-my improvements. Fig. 2 is an end view. Fig. 3 is a top plan viewof Fig. at is a horizontal section of the sliding plate or bar and a stationary one. Fig. 5 is'a view of the operative face of the stationary plate. Fig. 6 is a simii lar view of the reciprocating plate or bar.
In the drawings I have shown the operative parts of the machine as being mounted on a frame-work, consisting of the legs or standards A A, girts B B, and top pieces, 0 C. The
sired cxtentwithout materiallyaftecting the essential parts of theinvention, as will be readily understood. Upon the frame-work decracking, or grinding the grain, consisting of a horizontal stationary surface and a reciprocatingsurface. The former surface is formed upon an elongated plate or bar, E, which is manner as to be adjustable thereon. The attaching devices shown consist of slotted ears or arms projecting laterally from the plate or bar E, and set-screws 0 passing through slots This plate rests upon one of the top pieces, 0, of the frame, its operative face being in a vertical plane between the two said cross'pieces G O. The set-screws c e engage with the upper side of the cross-piece 0 upon Opposite tric, H, fastened thereto,
' rocati n g plate G.
the grain to enter between the to this plate or bar there-is a reciprocating plate, G, mounted parallel to the former, and adapted to break, crack, or grind the grain or meal betweenits operative face and the face D of the part E. The said operative face of the part G is corrugated, recessed, or ribbed that it may properly engage with the berries of the grain or with the particles of meal andefi ect the breaking or cracking.
The reciprocating mechanism which I have shown consists of a power-shaft, H, an eccenand a vibrating forked lever, I. The lever I, by means of the forked arms t", engages with the eccentric, and
v by means of a smaller fork, at t", engages with an arn1,'g, projecting laterally from the recip- The lever is pivoted at i to the top cross-piece, 0, though it may be secured in any other suitable stationary part. Power is-imparted to the shaft H by meansot a belt-wheel, H or in any other suitable manner, and it will beseen that when the shaft is r0- tating a reciprocating movement in horizontal paths will he imparted to the grinding-plateG.
, This plate orbar G is held in proper position vertically by means of the supporting cross-piece,
or by springs, and is held properly relatively to the stationary grinding-plate by means of a guide or way provided by a supporting-piece, G behind or outside of the plate or bar G, and fastened to the top of the cross-piece O. The operative faces of the stationary grinding or cracking plate or bar E and of the reciprocating plate or bar G are at their upper edges beveled,so as to form a passage-way to permit said operative faces. The stationary plate is at its ends formed with ears or walls 9, adapted to come in comparatively close proximity rocating plate, and arranged to prevent the grain or the'meal from escaping longitudinally from between the grinding-surfaces. The stationary bar E'is upon its operative face and immediately below the'beveled portion provided with recesses c 6, into which the grain passes immediately after leaving the passageway formed by the beveled faces d and 9 After the grain has reached thesei recesses it is (when the machine is in operation) immediately caught or engaged with by the reciprocatin g plate or bar, which operates to break, crack, or crush it into particles small enough to permit them to pass downwardly away from the plates. To permit the particles to immediately escape after being broken or cracked, I provide channels, grooves, orpassage-ways c e eacharranged between two of the upper initial receiving recesses or pockets, so that in whichever direction the reciprocating plate may be moving the particles will beimmeto the recip diately delivered to the one or the otherof the passage-ways, which extend to the bottom of the stationary plate or bar E. After the material has been operated upon by the breaking or cracking surfaces it escapes through the passage-way between the top pieces of the frame, and may be received into a hopper or any'other suitable receptacle, from which it may be carried by spouts or elevators to any desired point in the mill.
My invention is more especially applicable to producing fiourfromg'rain by whatrisrnow in the art known as the system of gradual re-.
duction-that is to say, lean employ a series of these machines having horizontally-arranged grinding-plates of substantially the character which I have described, and pass the product of one machine to the next in the series until it has been reduced to the required degree of fineness. In the machine which first receives the grain the plate or bar E is adjusted so as to merely crack the berries into large particles, preferably so as to break them into halves. After it is cracked-the material can he carried to any suitable scalping or cleaning mechanism for removing the fuzz and dirt, which, as is well known, can be better removed after the grain has been thus treated. ltis then returned to a reducing-machine similar to the one described, except that the stationary grinding-face D is adjusted somewhat nearer to the reciprocating face. After it has been operated upon, by this second machineit can be then carried to a cleaning device before subjecting it to further reducing operations, which latter can be carried on as long as it is necessary in substantially the way now followed in gradually reducing grain.
If desired, all the reducing-machines of the series may be arranged in a vertical line, and the material may lie-passed downward from one to the other after going through the appropriate cleaning mechanism at each stage. If preferred, the cleaning or scalping mechanism may be arranged in the same machine or in the same vertical series of machines.
A grinding or reducing mechanism of the kind I have described I have found to be much more desirable than rolls, disks, or stones,
which have heretofore been used for gradual reduction. Itis well known that the rolls and disks can be made only at considerable cost, and that the mechanism employed tooperate them requires a large amount of power.
The expense of a machine of my improved character is about one-tenth that of a machine of the ordinary kind employing rolls, and the power required to operate mine is about onefifth that of a roller-machine of the same capacity.
I do not wish to be limited to the specific form of supporting frame-work which 1 have shown, having this to illustrate in a simple manner a practical method of carrying out my improvements. Nor doI wish to be limited to the exact form of mechanism which I have shown for imparting motion to the reciprocatin g surface, as it will be readily seen that these devices can be easily varied by one skilled in the art without changing the important parts of the invention. Nor do I wish to be limited to the exact shape of the recesses or pockets 0 in the stationary grinding-surface, or to the exact shape of the escape-channels 0 below and between the receiving ones.
J J are metal springs, attached to the barGr at the ends, and also to the frame-work, as
- shown atj j. These springs operate to insure that the reciprocating plate shall move smoothly and greatly reduce the power required to operate it. Preferably these springs are so arranged as to support the plate or bar G- that is, so that it shall be flexibly mounted.
I do not herein claim any of the features which I have shown and described, except the combinations specifically set forth in the following claims, reserving to myself the right to claim all other patentable matters in another application which I have filed as adivision of this case.
What I claim is 1. Inamachinefor reducinggrain to flour, the combination, with the reciprocating grooved, recessed, corrugated, or ribbed plate, of an opposing plate having initial receptacles, pockets, or recesses e, and passage-ways which permit the material to escape after it has been cracked, substantially as set forth.
2. In a machine for reducing grain to flour, the combination, with a reciprocating grinding or cracking plate, of an opposing plate having initial receptacles, pockets, or recesses,
and escape passage-ways, each situated beplate, of an opposing reciprocating grinding or cracking plate, and springs arranged, substantially as set forth, to support or partially support flexibly said reciprocating bar or plate.
In testimony whereof I affix my signature in presence of two witnesses.
