Application filed December 14, 1910. Serial No. 597,230.

To all whom i may concern:

Be it known that I. Ina M. NnwnLL, citizen or' the lfnited States, residing at Minneapolis, lin the county of Hennepin and State ot ).iinnesfota, have invented certain new and useful 'ln'iproveinents in Sitters, ot which. the following is a, Specification.

lThis invention relates to eulinary implementsI and has particular referenee to an in'iproved form of sitter for use with flour, and the like.

jin ohject of this invention is to provide a reversible sitterv or one which has upper and lower chambers with the Sittingr means .interposed between the chambers, so ,that

the sitter. can be inverted to siit the contral section, the handle seetion havii'rtiy agi-- tators rigid therewith which projeet into the hodv vortion and are )ositioned ae'ainst' the sides ol the sereen to move thereagainst as the sereen is earried haelt and forth hy the roi-hing` olthe eentral Seetion.

The invention has for a further ohjeet to torni a sitter eomprisin;r hut l'ew parts. and having' the agitators and the vihrating haiidle thereot 'ornied olt one length otl wire and having' the hody ol' the, sitter so hinged upon the handle that the hotly may liev roeked liaek and lorth to thoroughly stir thi-.eoutentsand insure the pu^:-a g'e ol' every parliele tliereot' llii'oufjli the, sereen. or the liody eaii lie held rigid and the handle roehed haelt and l'ortli.

The invention has l'or a l'uiftlier ohjeeti to l'orni a sil'ter wherein the. aljitators are held trom undue eonlaet with the. sereen. and the l'rietion tlieielii' redueed.

l"or a toll understanding ot' the invention rel'erenee. iS to lie had to the following deseription and aeeoinpanying: drawing` in wliieh Figure l is a perspective view ot the eoniplete improved sitter. Fig. 2 is a vertieal eentral seetion taken through the handle of the saine. llig'. il is a horizontal section ot VSygieeifca'cion of Letters Patent.

Paten-ted Nov. '7, '1911.

invall the views ot the accompanying draw-` ing' by the saine reference charaeters.- Referring to the drawing the numeral ,designates the hody or central portion of the sitter which is disclosed of cylindrical form' open at its opposite endsand provided inidway of its ends with an annular outwardly.

pressed bead lt. The bead A11 vforms' auffannular channel within the central section l0 receiving?r the edge of a. @creen 12 which en-. gages across the inner portion of the body'.

Small openings 153 are formed through the hody l0 'and are vertieally spaced in registration t'ioni the opposite Sides of the screen l2 and through whieli the agitators pass.

slightl)7 from the tarea ol the saine. 'lhe re turned end ol the elongated loop terminates -in a centrally disposed arm ll lyiiip;l in the plane of the loop and terininatinpr adjaeent to the outer end ol the saine; 'lhe openings 13 are slightli elongated transversely ot'ljtlie liody l0 to admit otga swinging; movement,- ot' the inner ends ot' the agitators' ll.

'l`he wire l'roin' whieli the agitatorsl are i'orined passes outwardl)i through' the openings '13 and is lienty abruptly toward the opposite ends of the liod)y lt). assliown at l5. the ont .rardly lient portions hearing against tlnA outer lt'aee otl the hotly. The.

outer ends' otl the spindles l5 inerge'i'nto out-A turned arnis llt 'disposed in "vertieal registration and ai t provided with inturned prongs 1T engagingl in the opposite ends ot a handle tta. lt will ie noted, partieularly lroin Fig. 2, that the handle. 18 is fixedly mounted lietweeii` the outer ends of the aiins lf3 h v providing' radial depressions in the ends ol' the hardle to reeeive the iiidependent rotation otl the handle. Seeured upon the liodv 'l0 o| posite the openings lfl is a` plate lf) the pla e lieingtornied 'from a sheet of metal bent to conform to the curvature of the body 10 and transversely crimped, to receive a portion of the outwardly pressed bead 11. The plate 19 is provided with a transverse bead to bear over a portion of the annular bead 11 of the body and also provided with vertical beads 20 spaced slightly apart at their adjacent ends forming bearings for the vertical portions 15 of the agitator-s. At their inner ends the bearings 20 are rounded to form stops for the elbows orv bends of the agitators, to limity their movement toward each other. By this means an eicient hinged connection is produced between the agitators and the bead whereby the agitatorsare held from vertical movement or movement toward or away from the screen 12. The ends of the body 1Q project considerably beyond the estremi;` ties of the hinge portions 15 and are provided with tight fitting cups or end-sect1ons 22. Graduations 22b are preferably formed in the sides of the cups 22 by means of which the contents of the same may be measured. i

ln operating the sifter one of the cups 22 is drawn from the, central section and the' material` to be sifted placed therein, the quantity thereof being measured by the graduations 22h. The body 10 is now insei-ted and forced into vthe cup 22, when the operator inverte the entire sifter. The contents now in the sifter falls upon the upper side of the screen 12. The operator grasps the handle18 firmly and swings the arm from side to side when the hinged body 10 rocks upon the rigid spindles 15 and stirs the contents in the upper chamber. The agitators 14 are lixed to the handle and remain stationary with respect to the screen 12 carried in the body and produce the .disintegration of the materialand feed the par icles thereof through the screen 12 into the lowerchamber. If desired, the sifter is. again inverted to dispose the material again inthe upper chamber when the operation is repeated and a second sifting is etlected without removing the contents from the device. This operation may be carried on indefinitely until the required sifting is effected It'will be observed from Figs. 1 and 2 that when the device is supported by the handle r18 the low-eijsplndle 15 presses against the innerl face of the bearing 21 and serves as a pivotal support for the entire body 10, relieving the marginal edge of the openingl ofthe pressure or wear of the support while passing therethrough. The ag1tators 14s-disturb the material which rests upon the screen 12 and cause the same to pass through the screen into the lower Section or chamber 22.`

In the modified form, disclosed-in Fig. 5`

of the drawings, the central section 10 is provided with the outwardly pressed bead '11 carrying the screen 12. The fixed section, lincluding the handle 18 having arms 16 and spindles 15 carrying'the agitators 14 is of the same form as abovehdescrlbed. The 'difference resides in formifig the openings 13a fart-her 'from the bead 11 in registration with the inner ends of the arms 16, and in passing the arms 16 through the openings 13a to dispose the spindles 15 against the inner side of the v'central section 10. The plate 19h employed in this modified form is in two sections which are respectively sei.' cured against the inner side of the body 10 1 at the opposite sidesof the screen 12 and against the spindles 15. The plate sections 19 are provided with an interrupted bead 20tl for rotatably receiving the spindles 15. `rlhe beads 20 terminate short of the ends of the plate sections 19" and outwardly of the ends of the spindles 15 to provide end thrustbearings therefor, as is disclosed in Fig. 6. I

Having thusv described the invention what is claimed as new is A sifter comprising a body having an an,

nular bead intermediate the ends, a screen extending transversely of the Body and bearing in said annular bead, anagitator at each thereby and with vertical beads intersecting' the transverse bead and compressed at such intersection to form bearings for the vere` tically directed portions of the agitators". .I
