IMPROVEMENT IN MlDDLlNGS-BOLTS.
Specification forming part of Letters Patent No. 144,783, dated November 18, 1873; application led September 11, 1873.
and the former carried to the next bolt, this being repeated until the middlings become clear and pure.
In the drawings, Figure l represents an end view of my mddlingsbolts, showing their position, &c. Fig. 2 is a sectional plan view; Fig. 3, an end view, showing the ends of conveyer-boxes, and the manner of belting the bolts together.
The letters A, B, C, D, E, and F represent the series of bolts, which are arranged one above the other, as shown, and each having conveyers a c, and intermediate slides b b. G represents the driving-pulley, and which serves to impart motion to the whole series of bolts by the arrangement of bolts shown in Fig. 3. The middlings are introduced at the spout o, where they are carried into the bolt A, and are therein bolted by sifting through the different grades of cloth :into the conveyer a. The best portion of the product comes through one end of the bolts, and the light bran is carried to the other end, when,
by opening the slides b, the separated bran is allowed to pass onto the conveyer c, which latter carries off the bran at the point g, Fig. 2. The middlings are carried by the conveyer a, and emptied or caused to pass into the bolt B; (which is covered with a iner grade of cloth from bolt A,) and in this bolt the same operation occurs that is above described, the light bran being carried off at one end, and the inidrlhe combination of a series of bolts of small tember, 1873.
