and easily constructed and which will avoidthe necessity of using two hands to support and operate the same. Still another object of the invention is to provide a device having a minimum number of parts, struction without interfering with the efficiency of its operation.

With these and other objects in view the invention consists of a novel construct-ion, combination and arrangement of parts which will be fully set forth in the following specification, claimed and illustrated in the accompanying drawings in which Fig. 1 1s a vertical sectional'view through the sifter.

Fig. 2 is a top plan view thereof, referring to the drawings in detail the numeral 5 designates the body of the device which comprises a cylinder which is open on both ends as shown in the drawings. Secured about midway of the cylinder is a hemispherical sifting member such as the screen 6, and extending diametrically through the cylinder at a point in line with the axis of the hemispherical screen 6 is a shaft 7 on which the agitator to be more fully hereinafter described is mounted. The shield 8, is secured to the interior of the cylinder and extends upwardly from the upper edge of screen 6 to the upper end of the cylinder and forms the guide for the agitator operating spring.

The agitator above referred to is designated in its entiretyby the numeral 9 and comprises a plurality of bowed arms 1O,

from the ends of which are secured two hubs 11, arranged on opposite ends of the shaft 7. The body is provided with a handle 12, ex tending outwardly therefrom in a plane agitator may be within thereby cheapening the con innate CHARLES BRAUN, or BBOOKLILYNUNEW YORK.

from the longitudinal axis of the shaft 7 and in direct. alinement with the shield 8 in order that the operating handle of the easy reach of the hand of the user.;

In order to provide ameans for manipulating the agitator a fiat leaf springl3, is

secured atone, end to one of the arms 10,

while the opposite end of said spring extends upwardly to space ltwithin the shield 8, and is connectedto the operating handle 15 provided atfitsfupper end with a'thumb piece 16, which extends outwardly beyond ner as to overhang handle 12.

In operating, upon applying pressure to the thumb piece 16, it will be obvious that the handle 15 and spring13 will be forced downwardly thereby causing the agitator 9, to rock on the shaft 7 in such a manner that the ends of the arms 10 will rub against the screen 6, thereby sifting the contents of the cylinder. Upon releasing the pressure of the'thumb piece 16, the spring 13 the side edge of the cylinder in such a manwill tend to straighten and will impinge against the lower edge of the shield 8, thereby acting to return the agitator and handle 15 to original position or as shown in Figwl.

Obviously, repeated operation of the de- I,

vice will cause the agitator to rapidly oscillate and sift the contents of the cylinder through the screen '6. i

While in the foregoing there has been shown and described a preferred embodi ment of this invention, it is tobe understood that certain minor changes in the details of construction may be resorted to without departing from the spirit and scope of the invention as claimed. 7

,VVhat is clalmed 1S 1. A flour sifter comprising a cylinder, a

sifting screen arranged intermediate the ends of the cylinder, a handle 'securedto and radiating from the cylinder, an agitator pivotally mounted within the cylinder for through which said handleis adapted to reciprocate, said'guide retaining said resilient means flexed to cause said actuating handle co-operation with the sifting screen,'an agiby and having one end secured to the agitator, and a nonfiexible operating member 10 secured to the free end of said fiat spring for operating said spring and said agitator. Signed in the city, county and State of New York, this 18th day of January, 1921.
