SPECIFICATION forming part of Letters Patent No. 680,261, dated August 13, 1901. Application filed February 15, 1901. Serial No. 47,526. (No model.)
To aZZ whom, it may concern.-
Be it known that 1, JOHN M. LYMAN, a citi zen of the United States, residing at Cincinnati, in the county of Hamilton and State of Ohio, have invented a certain new and useful Machine for Breaking and Grading Starch and other Brittle and-Fragile Substances,of which the following is a specification.
My invention relates to an improved method of breaking and grading starch and other brittle and fragile substances; and the objects of my invention are, first, to reduce large lumps of starch and other'brittle and fragile substances to small lumps, making the largest possible percentage of lumps of a given size and the smallest possible percentage of pulverized material, and, second, to break and grade the material with the same machine without rehandling. I attain these objects by the mechanism illustrated in the accompanying drawings, in which- Figure 1 is a vertical section of the machine on the line Z Z of Fig. 2. Fig. 2 is a top view of the machine. Fig. 3 is an exterior side view. Fig. 4c is a cross-section through the line H H of Fig. 3, and Fig. 5 is an enlarged view of the gear operating the grading-sieves.
Similar letters refer to similar parts through out the views.
The machine is inclosed in the general framework A- Extending lengthwise through the machine over horizontal rollers or pulleys B B, and supported by additional rollers O O O to prevent sagging, slatted belts F are driven, upon which the substance S to be reduced is deposited. Above the slatted belt F upon the shaft D D D are placed circular steel disks D D D, revolving so as to travel at the same speed and in the same direction as the slatted belt F and at different distances above the slatted belt, as indicated in Fig. 1. Beneath the slatted belts are three sieves G G G, each sieve having larger meshes than the one immediately beneath it. These sieves slope toward the openings Q Q Q,where the substance is discharged from the machine. These sieves are driven backward and forward by means of the eccentrics and arms G,
The operation of this machine is as follows: The substance S to be reduced is fed into the machine upon the slatted belt F, which travels toward the first row of disks and which by the gearing shown in Fig. 3 is driven at the same speedas the slatted belt. The substance passes under the disks and is thereby partially reduced by the splitting action of the disks,and while the broken parts fall through the slatted parts F upon the sieve G the remaining larger parts S are carried forward and are treated in the same manner by the remaining series of disks 2 and 3. After falling upon the screens G G G the substance by means of the different-sized meshes is graded into three sizes of lumps and the pulverized material is removed by the conveyor M.
' Having described my invention, what I claim as new, and desire to secure by Letters Patent, is-
4 1. In a machine for reducing starch or other brittle or fragile substances, the combination of a horizontal traveling endless slatted platform, and a series of shafts located thereabove and carrying circular cutting-disks, said disks being placed with their edges at progressively-diminishing distances from the surface of the belt, and means for imparting to said disks and said belt a movement in the same direction, and at the same periph eral speed, so as to split and not either cut or crush the material.
2. In a machine for reducing starch 'or other brittle or fragile'substance, the combination of a horizontal traveling endless slatted platform, and a series of shafts located thereabove and carrying circular cutting-disks, said disks beingplaced with their edges at progressively-diminishing distances from the surface of the belt, and means for imparting to said disks and said belt a movement in the same direction, and at the same, peripheral speed, so as to split and not either cut or crush the material with a sieve or sieves placed directly beneath the belt and receiving the reduced material therefrom.
In witness whereof I have signed my name IOC to this specification in the presence of two subscribing witnesses.
JOHN M. LYMAN. Witnesses:
CHAS. M. LESLIE, CARRIE B. STUBERT.
