UNITED STATES PATENT ()FFICEO ANDREW L. HENRY, or L'ADOGA, INDIANA.

SIFTER.

SPECIFICATION forming part of Letters Patent No. 281,364, dated July 17, 1883.

Application filed January 22, 1883. (No model.)

To all whom it may concern Be it known that I, ANDREW L. HENRY, of the town of Ladoga, county of Montgomery, and State of Indiana, have invented certain new and useful Improvements in'Sifters, of which the following is a specification.

My said invention consists in certain improvements in that class of utensils known as sifters, whereby such utensils are rendered superior in the particulars of the operation of the rotary agitator and the separating and connecting of the several parts, as will be hereinafter more particularly described and claimed.

Beferring to the accompanying drawings, which are made a part hereof, and on which similar letters of reference indicate similar parts, Figure 1 is a top or plan view of a sifter embodying my invention; Fig. 2, a vertical sectional view thereof, as seen whenlooking the lower portion and the sieve.

to the left from the dotted line 2 z in Fig. 1; Fig. 3, a side elevation of the sifter when the top is swung open and the sieve removed; and Fig. 4, a detail sectional view on the dotted 'linex m in Fig. l.

In said drawings, the portions marked A represent the lower portion of the body of the sifter, B, the upper portion; 0, the sieve, and D the agitator.

The portion A is a plain cylindrical structure, preferably formed from tin or other suitable sheet metal. It has a hinge, a, thereon, by which the upper portion, B, is connected thereto, and a catch, a, to engage with a lug or hook on the part B, and thus hold the two parts together, as will be presently described.

The part B is a continuation of the part A when the device is in position for use, and is connected thereto by the hinge a. Its lower end is ensmalled somewhat, so as to fit inside It is provided with a handle, B, upon which the hook or lug b, which engages with the catch a, is usually placed. I

The sieve O is a common sieve, constructed preferably of wire-netting in the form of a hemisphere, the edge being bound or rimmed with sheet metal. The sheet-metal rim is made of just sufficient size to fit closely inside the portion A of thebody, as shown'in Fig. 2, and is, in turn, adapted to receive the lower edge of the portion B. The three parts B, O, and A thus nest into each other when the device is in its ordinary or working position, and thus close joints are formed, through which the flour or meal cannot escape while being sifted.

The agitator D is composed of a shaft having hubs (1 (Z and wires bent to conform to the internal shape of the sieve and mounted in said hubs. The shaft is bent into the form of a crank at one end, outside the body of the sifter, and should be provided with a handle, d. The hub dis secured fast to the shaft, and thus said shaft carries the wires with it as it is revolved. The hub d is hollow, and is not fastened to the shaft, but merely secures the ends of the wires together. The hole in this hub, being considerably larger than the shaft, permits the wires to vibrate somewhat as the agitator is revolved, and permits said wires to be in contact with-the sieve at all times, notwithstanding some inequalities that may exist in said sieve. This is a valuable result, and one of the distinctive features of my invention. The bearings for the shaft of the agitator are formed by simply cutting notches in the lower edge of the portion B, as shown most plainly in Figs. 3 and 4, and thus the agitator is made easily removable when the portions A and B are parted, as shown in Fig. 3.

Having thus fully described my said invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a sifter, a rotary agitator consisting of a shaft, hubs, and wires, one of said hubs being hollow and surrounding the shaft loosely, thereby permitting the wires to vibrate some what, substantially as set forth.

2. The combination of the two body portions A and B, separably connected together, the sieve C, and agitator D, forming a sifter, as specified, the sieve 0 being adapted to fit inside the bottom portion, A, and the upper portion, B, being ensmalled at the lower end, and thus adapted to fit inside said sieve, thus providing for a continuous fiow of the flour from top to bottom through the sieve without permitting any portion to escape through the joints where the several parts come together, substantially as shown and described.

In witness whereof I have hereunto set my hand and seal, at Ladoga, Indiana, this 16th day of January, A. D. 1883.
