MARK F. MORSE, OF BOSTON, MASSACHUSETTS.
Letters Patent No. 60,539, dated December 18, 18136.
l651112rtgemlxz:stimmt tu im .time ettas atmt mth making part nf 111e smut. p A
' lO ALL PERSONS TO WHOM THESE PRESENTS SHALL COME:
i Be it known that I, MARK F. MORSE, of Boston, in the county of Sul'olk, and State of Massachusetts, have invented a new and useful-'or improved Flour Sifter; and I do hereby declare the same to be fully described in the following specication, and represented in the accompanying drawings, of which- Figure 1 is an end elevation. i
Figure 2 is a longitudinal section; and
Figure '3,' a transverse section of it.
In .the drawings, A denotes a cylindrical drum having its periphery .made of woven wire or a foraminous plate. Furthermore the said drum is constructed in twosegmental parts a b, one of which is hinged t0 theother and constitutes a door thereto, a turn button, c, beingapplied to the door for the purpose of keeping it clos'ed'while' the drum A may be inv operation. A shaft, B, runs axially through and is iixed to the drum or .its heads, d d, Y
and is supported in suitable bearings, e f, applied to a frame, C, within which the drum is placed.' The shaft also goes through a plate or disk, D, provided with a series of cams, ggg, arranged in a circular path on it. A. handle, fixed on one end of the shaft has a stud, z', extending from it and so as to touch either of the said cams. Between the disk D, and a shoulder, c, fixed on the shaft, there is a spring, l, which encompasses the shaft, and serves to move` the drum in a direction opposite to that inrwhch it may be moved by the' action of one of the cams. Thereis also placed on the shaf/t and between the shoulder k, and another such shoulder, l', fixed on the shaft, a cap, E, which is a segment-'of a drum somewhat larger thanhalf of it. i This cap should be so applied to the shaft as to be capable of being turned freely thereon, and should be provided with a stopping flange m, (or its` equivalent,)arranged as shown in the drawings. This flange serves to arrest the movement of the cap in its proper position for either wholly covering'or uncovering the sifting drum A. The cap E, when over the drum while' it maybe in the act of sifting, will prevent the upward'escape of the material which may be within such drum. So, when the cap is turn-ed down underneath the drum, such cap will serve tocat'ch and retain any of the material which may drop from the drum, either while it may'be in revolution or beY in the act of heingtransported fromone placel to another. Thus, it-will be seen, that the, cap arranged with and applied to the drum and its shaft is of advantage in other respects than as a mere casing to extend over the drum. By laying hold of the handle and putting the sifting Vdrum in revolution, such drum during such revolution will have a series of endwise, sudden, concussive movements imparted to it, such as will greatly facilitate the disturbance of any material while within it and in the act of being sifted.
I do not claim a rotary sifting druimbut what I claim as my invention is y The combination and arrangementff the disk D, its series of cams g g g, the stud z', and the spring l, with the sifting drum, its shaft, and supporting frame, the whole being to operate as specified.
