UNITED STATES PATENT OFFICE.
DANIELc OOLEY, OE NEw YORK, N. Y.
IMPROVED FLOUR-SIFTER.
Specification forming part of LcttersPatent bla-118,520, dated July 4, 1865.
To all whom it may concern.-
Be it known that I, DANIEL C. CoLBY, of
the city and county of New York, in the State spective; Fig. II, a view of the shaft detached from the box; Fig. III, a sectional elevation divided transversely.
Letter A represents a box open at the bottom B, a shaft ruiming longitudinally along the base of the box A; C, a case inclosing the' base of the box A, and extending downward keeps the our from iiying about as it leaves the sieve; D D, two standards that sustain the sieve-box A, and, in conjunction with the pieces E and F, form the waste or bran box just in the rear of the box A. E and F are two narrow strips of thin board arranged between and fastened to the standards D D in such manner as to give support thereto, and, in conjunction therewith, to form the waste or bran box, as seen in Fig. III. g g and h are stripsof leather, rubber, or other suitable substance, to press gently upon the surface of the sieve; I, a semi-cylindrical sieve of wire-cloth, and suitablyfastened to the lower edges of theends and sides of the box A 5 J, the crank with which to revolve the shaft B lc, a small straight rod running through the standards D D, and through hthe end pieces of the box A, as seen in Fig. I; L, a simple board forming a base, and to it theV standards D D are rmly fastened. M is a coarse screen placed just above the shaft B in the `box A, and so that the rubbers y g shall jostle it as they pass, thus causing the flour to fall through, yet leaving any bits of wood,1
nails, or the like on top of the screen. This screen also prevents the our or meal from crowding the shaft when a large quantity is thrown into the box A at any one time. a is l a handle to steady the box A by when de tached from the other parts, as it may be often thus used. r
The obj ect of my invention is to secure a dehands to be applied to the flour or meal, shall avoid all the dust usually attendant on the process of sifting flour or meal, and one that also affords a ready way of throwing off the waste when desired. l v
The box A, the standards D D, and the strips E and F, I make of anylight wood from threeeighths to one-halfinch in thickness; the shaft B of wood or any other suitable material.
The strips g g and h, Iarrangeon the shaft B,
for the following reason-viz., so that any little should not go through the interstices of the sieve, may be moved one side and not crushed, and be thrown out with the bran or otherwaste. This is a very important feature, and one heretofore altogetherignored in sieves of this general character. l
The screen M may be made of coarse wirecloth or perforated tin.
The rod 7c sustains the box A ata sufficient height to allow the iour pan or receiver to sit beneath, as seen in Fig. Ill. On this rod the box A is tilted in order to pour off the waste, as may be seen in Fig. III.
What I claim as my invention, and desire to secure by Letters Patent, is`
1. The use of the shalt B, provided with one or more rows of the strips g g and h, in combination with the box A and the sieve I, and with or without the .screen M, substantially as described, and for the purposes set forth.
2. The combination and arrangement ofthe box A, the standards D D, the rod k, and the forth. y
DANIEL C. COLBY. lVitnesses:
