IMPROVEMENT IN MIDDLINGS-SEPARATORS.

Specification forming part of Letters Patent No. 173,734, dated February 22, 1876; application filed VMarch 16, 1875.

To all whom it may concern:

Be it known that I, WILLIAM J. MEERITT, of Bardolph, in the countyof McDonoughand State of Illinois, have invented au Improvement in Middlings-Separators; and I do herebydeclare that the following is a full, clear,

. and exact description thereof,which will enable others skilled in the art to make and use the same, reference being had to the accompaaround a hollow center-post, through which a scribed.

rotating sha-ft passes, which, by means ot'- arms andl suitable appliances attached to the center-post, gives the proper agitation that is.4

required, as will be hereinafter more fully de- Figure l is a perspective View of the separator, with part of the top frame cutaway. Fig.

2 is cross-section ot' the separator-frame.A

Fig. 3 is the sieve -frame, bottoln side up, showing the manner of lacing the cloth to the iframe. Y

In the drawings, Figs. l and 2, B B B B represent a frame, which is formed by means ofthe bolts r r r ll", attached to the center-post D. H H H H represent a frame, which is attached to the inside of the frame B B B B in an incline or spiral form around said frame. Between this frame andthe center-post l) the sieve-frames G Gr Gr G are placed. I I I I represent leather-straps, which are attached at 'their lower ends to the frame B B B; the up- 1 per end to the center of cross-frame s s s s of the stand A. (See Fig. l.) The shaft C 'passes through the center-post D, (see Fig. 2,)

which is bored out sufficiently large to allow the necessary vibration when in operation. At each end of the center-post D is rmly attached a rim, E, which has teeth projecting inward., Opposite these rims on the shaft G. arms a a areattached.

Fig. 3 shows .the under side of the sieveframe, showing the manner of lacing or tightening the cloth. The bolting-cloth is bound on the edge with canvas of sulicieut width to lap over the edge of the frames, and is filled with eyelets, which the lacing-cord passes" through, by which the cloth can be stretched to any desirable tightness.

The operation is as follows: Motion is applied to the pulley d, and as the shaft() commences to revolve the arms a a strike against the teeth on the inside of the rim E, which gives the separator a continuous vibratingr motion, and the separator being hung upon the leather straps I I I I, the required agitation is by thismeans easily produced. The middlings or other material to be separated are let in on .the upper sieve, which, being. on an incline, the agitation ot the separator causes all the branl and other impurities that do not pass through the first sieve to pass over the edge and fall on the second sieve, and so on around the whole series of sieves in the same manner, until they pass out ot thesepav rator. Y

, By having diierent `grades of the cloth `on the dii'erent sieveft'rames, will make different grades ot' the material separated, and each grade can be taken out under each sieve-frame if necessary, or only one or two places, as may be desired.

Having thus fully described my invention,

whatI claim as new, and desire to secure by Witnesses Tnos. J. PRICE, J. M. PRICE.
