Serial No. 166,043. (No model.)
To all whom, it may concern:
Be it known that I, RICHARD ALLENREW, acitizen of the United States, resid-ing at Poincroy, in the county of Garfield, W'ashington Territory, have invented certain new and useful Improvements in Middlirigs-Purifiers, of which the following is a description.
Figure l is a longitudinal section through myimproved middlings-puriiier. Fig. 2 is an end view of the same, with the wood-work at the rear removed.
My invention relates to those middlingspurifiers which are provided with vibrating sieves through which the middlings are passed and it consists iu the detailed construction and combination of the parts hereinafter fully described, by which the efficiency of the machine is greatly increased, and by which it is made to occupy less floor-space than themachines at present in use.
In the accompanying drawings, similar letters of reference indicate corresponding parts in both the iigures.
A is the framing ot' the machine, in which is arranged a series of vibrating sieves, B, which work in combination with the brushes C, situated on the under side ot' them'. c are the arms which carry the brushes and connect them to the upright shafts D, from which they receive theirmotion. rIhe upright shafts D are connected together by the bar d, fastened to the ends of arms d, so that the brushes may always move in the same direction.
E is an arm fastened on one of the upright shafts Dand connecting it to thesliding frame e, which receives its motion vfrom the pin e', situated on the side ofthe spur-wheel c?, and projecting therefrom. This frame converts the rotary motion which the spur-wheel c2 derives through a suitable train of gearing from the driving -pulley E into a reciprocating movement of arm E. 'Ihe sieves B are fed from the hopper Z1, and are suspended by springs b', which allow them to vibrate. The sieve next below hopper b is connected to the sieve immediately beneath it,and the remaining sieves are also similarly coupled together in pairs, so as to have the same vibrating motion. Gather-boards b2 are provided to catch the clean middlings which fall through the sieves, and return-slides b3 convey all the middlings which pass over the tail ot each sieve to the head ot' that sieve next below it.
G is an elevator, which conveys the middlings from the bottom half of one side of the machine to the hopper `gat the top of the other half ofthe machine.
H are shafts provided with driving-pulleys 7L and eccentrics h', for working the sieves B through the springs h2. One of these springs is connected to each side of the lower of each pair of sieves, and is provided with a separate eccentric for working it.
I is a chamber provided with afan, z', driven by the pulley t" on the shaft it, which is supported in suitable bearings in the framework A.
J is an automatic regulating-valve, which keeps the air which passes through the machamber I.
K are slats arranged in two separate series between chamberI and the sieves. rlhe volume orindraft of airpassing from the sieves to the fan can be regulated by opening these slats, more or less,as occasion requires.
L is an elevator, which conveys coarse middlings from the lower part ofthe machine to the hopper Z,at the top and o'n the same side of it, from whence they descend between the slats, as shown by the arrows in the drawings, and are passed through the bottom sieve again.
M is a divisionplate which separates the chamber in which the two bottom sieves work.
N are conveyers worked from the drivingpulley E through a suitable train of gearing. These conveyers remove the 4purified middlings from the bottom of the machine.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-
1. The combination ot" the series of sieves vB, the series of brushes O, arms c, carrying said brushes, upright shafts D, bar ci, and arms d', arm E, sliding-frame e, and spur-wheel e2, provided with pin e', for working said sliding frame, substantially as described and shown, l valves K, chamber I, the fau i, the elevator L, and for the purpose set forth. and the hopper Z, arranged in a plane inter- 2. The combination of the suspended sieves mediate of said valves for returning the coarse B, the driving-shafts H, provided with eecenmiddlings a second time to the head of the botr 5 5 trios h', the pitmen h, the upright shafts D,the tom sieve, substantially as described and brushes C, the arms c, carrying said brushes, shown. the bar d, arms d E, sliding frame e, and spur- T Wheel provided with a pin, e', substantially RICHARD ALLEN RE as and for the purpose set forth.

1o 3. The combination of the sieves B, gather- JOHN W. RAUCH,
