UNITED STATES PATENT OFFICE.

JOHN W. WOODFORD, OF PHILIPPI, WEST VIRGINIA; ASSIGNOR OF ONE-FOURTH T WILLIAM A. MORLEY, 0F ATLANTIC CITY, NEW JERSEY.

FLOUR SIF'IER.

Application filed November 6, 1925. Serial No. 6?,335.

This invention relates to new and useful improvements in sitters, and particularly to flour sitters.

One object of the invention is to provide a device of this character which is simple in construction, durable and effective in use, and which can be manufactured at a comparatively low cost.

Another object is to provide a sitter having an agitator therewithin, constructed and arranged so that the said agitator may be easily manipulated by the thumb of the hand which grasps the handle of the'device.

Other objects and advantages will be apparent from the following description when taken in connection with the accompanying drawing.

In the drawing:

Figure l is a vertical sectional view through a sifting device made in accordance with the present invention.

Figure :2 is a vertical sectional view taken in a plane at right angles to that of Figure 1.

Referring particularly to the accompanying drawing, 10 represents the metal shell of the sitter, which has the ordinary loop handle 11 secured to one side thereof. cured in the lower end of the shell 10 is the concavo-convex sifting screen 12. Disposed transversely through the upper portion of the shell, and extending from a point adjacent the handle 11, is a shaft 13, the opposite ends of which are fixed in the walls of the shell. In the end of the shaft, adjacent the handle 11, there is formed an enlargement 14. A wire yoke 15 has one end formed with an eye 16 which receives one end of the shaft 13 therethrough, within the shell, and a second eye 17 which is engaged on the other end of the shaft, between the enlargement 14 and the adjacent side of the shell. This lastnamed end of the yoke is continued upwardly above the upper end of the shell, and thence outwardly thereof, where it is formed with a fingerpiece 18, arranged in position to be engaged by the thumb of the hand which grasps the handle 11, whereby the yoke may be rocked, and the main portion thereof caused to scrape on the concave part formed with the coil turns 20, which are engaged on theshaft 13 between the eye 17 and the adjacent side of the shell 10. One end of the spring 19 is formed with a hook 21 which is engaged with the arm of the yoke 15, above the eye 17, and the other end anchored in the shell at a suitable distance from'the other side of the adjacent end of the shaft 13. The normal tendency of the spring is to expand and force the adjacent end of the arm of the yoke away from the shaft whereby to cause the yoke to slide toward the opposite side of the screen. The operator presses the fingerpiece' 18 in the op posite direction, against the tension of he spring, whereby to rock the yoke in the op posite direction, and upon releasing pressure on the fingerpiece, the spring will return the yoke to normal position. Thus, by pressing the fingerpiece and releasing the same, the

yoke may be moved backwardly and forwardly across the screen, with the result that the operator can hold the sifter, and manipulate the agitator with one hand.

What is claimed is:

A flour Sifter comprising a shell, a sifting screen in one end of the shell, a transverse shaft extending through the opposite sides of the shell'and having a loop adjacent one end, within the shell, a wire yoke in the shell with its hight portion contacting with the screen, one of the arms of the yoke having a terminal eye receiving the shaft therethrough, the other arm of the yoke having an intermediate eye receiving the shaft therethrough, said other arm being extended above the shell to form a hand grip, said loop preventing movement of said. eye on the shaft inwardly of the shell, and a spring having its intermediate portion coiled about the shaft between the loop and shell wall and having one end anchored in the shell wall and the other engaged with the hand-grip.

In testimony whereof, I ail-ix my signature.

JOHN W. WOODFORD,
