Application filed September 14, 1909. SeriatNo. 517,625.

To all whom it may concern:

Be it known that I, GEORGE .MCEAUHRON, a citizen of the United States, residing at Forsyth, in the county of Marquette and State of Michigan, have invented new and useful Improvements in Flour-Sifters, of which the following is a specification.

\p This invention relates to flour sifters,and its Ob ect is to'provide a simple, ethcienty -.and inexpensive construction of sifter hav ing an oscillatory screen adapted to be actuated in one direction by the fingers ot the hand gripping the handle of the device and in the reverse directionby spring action,

in character, so that the flour may be quickly and conveniently sifted.

The invention consists of the features of construction, combination and arrangement of parts hereinafter fully described Kind claimed, reference being had .to'the ac on"- panying drawings, in which Figure 1 is a vertical front to rear section through a siftei" embodying .iny invention. Fig. 2 is a vertical transverse section of the same on line 22 of Fig}v 1'.

Referring now more particularly to the drawing, ldesignates the body of the sifter, which comprises a can or receptacle prefer- 'and bottom, sai'd receptacle being provided at rear with a vertically disposed loail shaped or looped-handle 2 for convenience in handling and transporting the same.

Arranged within the receptacle is a screen 3 of wire or other Woveninaterial suitably secured to the walls of the receptacle. Arranged above this screen is a rotai -y agitator cinnprisingcross rods t carried disks 7 on a shaft '8, journaled at its ends in bearing,opcn iiigs 9- formed in the sides of the receptacle. Each rod andits arms may be conveniently made of a single piece of l .U forin, as shown.

The lower end of said lever 13 is formed with a coil .14 and an angular-1y bent arm 15 belowthe coil, which arm passesdown through a slot in the lower arm of able manner. The rear end of the pitman the handle 2 and bears against the. under side thereof. rA' clip or suitable fastening 16 engages both the coil 14 and arm 15 and secures the lower end ofthe lever 'in a firm finann'er to the handle, while permitting freecoil.

Normally the crank arm or connection 12 ofcontraction and expansion of the and the lever 13 lie in an upwardly and forwardly inclined position, so that by 1pulling'baclr upon the lever by means of the h ngers of the hand grasping the handle 2 the shaft and agitator may be rotated in one direction and the coil 1 at the same time contracted, whereby upon releasin' the leverthe agitator will be rotated in t e reverse upon'and releasing, the lever the agitator may be rapidly oscillated, so that theflour will be quickly and conveniently broken up I direction. By thus alternately'drawing back and sifted into apanpr other vessel below the receptacle.
