ALVIN CRAIG AND WILLIAM GUNNELL, OF CADIZ, OHIO.
SCALPER, GRADER, AND PURIFIER.
SPECIFICATION forming part of Letters Patent No. 736,364, dated August 18, 1903.
Application filed June 25, 1902. Serial No. 1131136. (No modelnl .To @ZZ whom it may concern: Beit known that we,ALv1N CRAIG and WIL- LIAM GUNNELL, citizens of theUnited States, residing at Cadiz, in the county of Harrison and State of Ohio, have invented certain new and useful Improvements in Scalpers, Graders, and Purifiers, of which the following is a specification.
In machines for bolting flour, purifying so middlings, and cleaning cereals it hasl not been feasible to use a current of air with the cleaning machinery when mounted to receive a gyratory movement.
In accordancewith this invention the purifying mechanism is mounted to receive a gyratory motion, and means are provi ded to' subject the material simultaneously to a current of air whereby the operation is rendered effective for scalping, grading, and purifying the zo middlings and bolting the iiour, and it is pos- 4o fier embodying the invention.
sible to reduce the number of sieves or separating elements. This invention also saves handling of the stock from roll to purifier and back again to roll and enables a minimum amount of power being expended for a given result as compared with machinery in general use.
For a full description of the invention'and.`
the merits thereof and also to acquire a knowledge of the details of construction of the means for effecting the result reference is to be had to the following description and drawings hereto attached.
While the essential and characteristic features of the invention are susceptible of modiiication, still the preferred embodiment of the invention is illustrated in the accompanying drawings, in which- Figure 1 is an elevation of a middlings-puri- Fig. 2 .is a central longitudinal section of the sieve-box, on a larger scale. Fig. 3 is a vertical section of the means for imparting a gyratory motion to the sieve-box.
Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.
The sieve-box is indicated at 9 and is sus- .5o pended by rods A or other hangers from the venient. An inlet is provided at 1 for the entrance of the break-stock.v
16 indicates the outlet for break-stock'to be passed back to the roll or mill to be reground.
2 is the scalping-sieve, which separates the middlings and flour from the break-stock, which drops to the division-board 3 and goes to 4 and drops to sieve 6. A` current of air enters at 18, passing up through the sieve 6, removing all light, fiuify, and dirty stock that is unfit to be mixed with the flour, and takes it out at the chamber 5 into the air-trunk 14 to the fan 15, which discharges it into a dustcollector or room. The flour passing out at 7 goes to the liour-chest. The middlings leave sieve 6 at 20,thorou ghlyd usted, and drop to the sieve 9. Air enters at 1S, passing up through sieve 9, taking from the middlings all the linecut bran, passing it out into the air-chamber 8, and into air-trunk 14 to fan 15, into dustcollector or room. At 17 coarse middlings leave sieve for roll to be reground. At 10 ne middlings leave machine for roll to be reground. 12 represents flexible spouts made of heavy ticking, with a wire coil in to keep spout from collapsing with the air-suction on them. It gives direct connection from sieve-box 9 to air-trunk V14. 13 and 182 are valves to regulate the air on sieves to suit the different stock. As many sieves and valves as are necessary to handle the stock can be placed in sievebox.
The actuating means for the sieve-box may be briefly stated as follows:
B is the balance-wheel,wrist-pin dislnwristpin, and bearing.
C C forms the journal at the lower end of B and runs in box D, which is filled with oil.
E is wrist-pin that is connected to sievebox 9. l
F is weight to counterbalance the sievebox 9.
G is a rod to hold ,weight F, which can be moved in or out to balance the sieve-box when in motion.
H is spindle that drives the machine and is made fast in the plate B, runs through box D at J, and has three-eighths inch clearance at J.
N forms the journal and runs in bearing K, which is babbitted, which can be adjusted to TCO points C C as they Wear by set-screws L, that are fastened to wedge M. At the end of the spindle is a box, as box D.
A machine constructed in accordance with this invention will scalp, grade, and purify the middlings and bolt the iiour from the breakstock and ground middlings. It takes the place of the scalping-reels, flour-dressers, or boltingreels and purifiers. It is three machines in one and will do more and better work than any other machine for sifting flour. The current of air passing through each sieve keeps an even temperature in the machine at all times. By its rotary motion all light and fluffy stock works on top of the heavier stock. The aircurrent passing through the sieve takes it all out of the machine to the dustcollector, leaving a clean stock to bolt, which gives the machine a greater capacity than any other sifter and a clean er flour. The air-current is so arranged that the miller has full control of it. By a system of valves he can adjust the current of air to suit each sieve.
The stock isV very gently handled, no forcing or rubbing is done, as in many sifter improved machines, having ample cloth surface to handle it gently, having the rotary motion with air-suction, thereby giving it greater ea pacity than any other machine on the market.
Having thus described the invention, what is claimed as new is- A middlings-puriiier comprising aclosed sieve-box, suspending means therefor, operating means for imparting a gyratory motion to the sieve-box, a scalping-sieve within the upper portion of the box, an inlet for the break-stock, an outlet from the opposite end of the scalping-sieve extended through the box and its bottom, oppostely-inclined separating-sieves belowT the scalping-sieve, returnboards belowr the several sieves, valved inlets opening into the box at points intermediate of the separating-sieves and the respective return-boards, air-chambers above the respective separating-sieves having their lower sides perforated throughout their extent, a station? ary air-trunk, means for creating a suction therethrough, and valved connections between the air-chambers and air-trunk having iiexible portions, substantially as specified.
In testimony whereof we affix our signatures in presence of two witnesses.
