To all whom it may concern.

Be it known thatl, CHARLES J. jl nrn'rny.

a citizen of the United States, residing at Los Angeles, in the county ot'Los Angeles and State of California, have invented a new and useful Flour Sitter, of which'the following is a specification.

This invention relates to flour-sitters and particularly directed to a typeotdevice in which, the flour, meal, or similar substances may be repeatedly sifted before being discharged therefrom.

An object of the invention to provide a sitter of theabove characterin which the entire operating mechanism is carried by a single member and in which said member constitutes a means for reversing the sitter.

Another object is toprovi'dea sitter having a tubular handleand reversing memb'er journaled therein and extended outwardly as an extension of the handle pro; riding a hand grip portion by which the member is manipulated, and providing: an operating: shaft associatedwith an agitator within the sitter "and, extending through said member for manual rotation.

Various other objects and advantages will be more fully apparent from .the {following description of the accompanying drawings, which form apart of thisdisclosure, and which illustrate a preferred form ofembodiment of the invention.

Qt the drawings: Figure 1 is a plan view oi my improved sitter. with one of the cover members removed. v r v Fig. 2 is a section on line 2- 2 ot-Ifig. 1. Fig.8 is a section on line'33 of Fig; 1. Fig". 4c is a detail section on; line 4%4 of 2. i V F ig. 5 is a perspective view'of one of the cover members;

Referring to the drawings; 1 designates a cylindrical hollow body open at its opposite ends and provided at its medial portion with a tubular handle 2 normal to the axis of the body, and 3-4 designate cover members closing the body.

J ournaled in the tubular handle 2 is a reversing member 5 in the form of a cylindrical plug, preferably constructed of wood, and extended outwardly to form an exten sion of the handle and provided with a.

hand-grip 6 for manual manipulation of the member The inner endof the member 5 is flush with the interiorsurfacelotj thebody wall and carriesa slftermembercomprisnga circular ring T closely contactin-g the wall of the body with its ends 81 driven into the member 5, and a' foraminous -hemispherical element 9 formmga partition across the body v 1. Associated. with the sitter member is a rotary (agitator comprising hemispherical arms 10 which arej carried upon the inner end of an operating shaft or rod 11 journaled in the member 5. and extending through one side of the toramin'ous element 9. :The shaft 11 extends through the-member 5 and its outer end isbentin the torm of a crankhaving a knob 12 at its outer'e nd to facilitate a 'rn'anualrotation otthe'shaift.

The member 5 islimited in its rotation to one-half ofa revolution, byfa screw 13 carried by said member. and {en a ing through a slot 14 in the tubular handle-2..

With the device as shown in Fig. 2.,the cover 3 will be removedandfa, quantity of iiour or other materialplaced intothe chamber 15. The cover, ,3"will thenbe replaced I and the shaft 11 rotated to'si ft thematerial' throu h the foraminous sift r mernber t) ,h into the chamber 16 f When ;all the. material has been sifted into the chamber 1.6,the, reversing member 5 will be rotated one-half ofafrevolution to position the sitting member. "9 on the catedin dotted lines 'inFig. 3) andthe entire device will then be turned overgthe material in the chamber 16 dropping uponthe sifter member :9. Y p

The shaft will again be rotated to sift the material, a second time throughv the ,foraininous sitter member 9'andl intothe chamber 15, this operationbeing repeated until the opposite side. of the agitatorjlO;i (asi,indimaterial has been sifted. a ,.desiredlnii mber of timesi when one or. the other of the' c'o'v; ers 3t may be' removed for the purp of discharging the material from the sitter.

In the device described above, I haveprovided a reversible flour-Sifter of cheap,

strong, and durable construction, which may be operated with maximum ease and speed, and in which the'operating shaft and sitter member have no direct bearing in the walls of the body such as would require the walls to be apertured to receive them, this being important as it is evidentthat such aper-' tures and their engaging parts are not usually in this type of device, constructedwith such care as to prevent leakage of the flour therethrough, and further the construction illustrated herein permits a maintaining of the smooth exterior surface of the body.

It Will be noted that excepting for the tu-' stood that the invention is not to be limited in this regard, for it is susceptible of: em bodiment in various other forms such as come Within the scope of the following claims.

I claim:

'1. In a device of the nature disclosed, a cylindrical body having a laterally extended tubular handle, a reversing member journaled in said handle, an operating shaft journaled in said member and extending exteriorly for manual rotation, an agitator secured upon thevshaft Within the body, a foraminous sifter member secured to the reversing member and forming a partition across the body on one side or" the agitator, the reversing member being operable to alternately position the sifter member on opposite sides of the agitator.

, 2. Ina device of the nature disclosed, a cylindrical body having a laterally extended tubular handle, a reversing member ,journaled in said handle, an operating shaft journaled' in said member and Wholly supported thereby, said shaft extending exteriorly for manual rotation and inwardly into the body, an agitator secured upon the shaft Within the body, a foraminous Sifter member Wholly supported upon the reversing member and forming a partition across the body on one side of the agitator, and means between the tubular handle and the reversing member limiting the rotation of said member to one-half of a revolution, the reversing member being operable to alternately position the sifter member on opposite sides of the agitator,

3. In a device of the nature disclosed, a cylindrical body having a laterally extended tubular handle, a reversing member journaled in said handle and extended outivardl therefromto form an extension of half of a revolution whereby said member i may be operated to alternately position the sifter member on opposite sides of the agitator.

4:. In a device of the nature disclosed, a cylindrical body having opposite open ends and provided With a laterally extended tubular handle at its medial portion, removable cover members for closing the ends of the body, a reversing member journaled in the tubular handle and extended outwardly therefrom to form an extension of the handle and provide a handgrip portion for I manual manipulation of said member, means permitting only 'a half rotation of said member, an operating shaft journaled in said member and. extending into the body, the outer end of the shaft extending exteriorly and bent to form a crank for manual rotation of the shaft, a rotary agitator carried by the shaft Within the body, a foraminous siftermember of approximately hemispherical form carried by the reversing member and forming a partition in the body on, one side of the agitator, the reversing member being operable to alternately position the sifter member on opposite sides of the agitator.

Signed at Los Angeles, Calif, this 16th day of May, 1922,
