JOHN N. BEALL, OF GREENFIELD, ILLINOIS.

FLOUR BlN AND SIFTER.

SPECIFICATION forming part of Letters Patent No. 425,286, dated April 8, 1890.

Application filed October 26, 1889. Serial No. 328,331. (No model.)

To all whom it may concern.-

Be it known that I, JOHN N.. BEALL, of Greenfield, in the county of Greene and State of Illinois, have invented a certain new and useful Improvement in Flour Bins and Sifters, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification.

My invention relates to that class of flour bins and sifters wherein a quantity of flour may be kept and taken sifted ready for use when desired; and my invention consists in features ofnovelty herein after fully described, and pointed out in the claims.

Referring to the drawings, Figure I is a front elevation of my improved device. Fig. II is a vertical section taken on line II II, Fig. I. Fig. III is atop view of the sifter removed. Fig. IV is a section taken on line IV IV, Fig. II. Fig. V is a detail view of the detachable hinge for connecting the sitter to the bin. Fig. VI is a detail view showing the socket for the handle of the sifter. Fig. VII is a side elevation of the device, showing it lowered. Fig. VIII is aside elevation showinga modification of the rods for supporting the device. Fig. IX is a section on line IX IX, Fig. VIII.

The bin or vessel for receiving the flour is composed of a main part or receptacle 1, circular in form, provided with a lid 2, and which terminates at its lower end in a contracted portion 3, from which projects a neck 4:, to which a detachable cylinder 5, for holding the sitting device, is attached at one side by means of a detachable hinge consisting of a ring 6, secured to the flange 4: at 7, and a hook 8, secured to the cylinder 5, and at the other side by a spring-catch 9, secured at 10 to the neck 4, and engaging with a pin 11 on the cylinder 5. cylinder 5 is a cap 12, for catching any flour that may drop through the sifter.

In the lower end of the cylinderii is a screen 13, of wire-gauze or perforated metal, through which the hour is sifted by means of an agitating device, which I will now describe.

Secured to the upper part of the cylinder 5 is a spider 14, (see Fig. II,) and in which is formed arectangular frame 15, (see Fig. 1H,) for the reception of abevel geanwheel 16, car- Fitting over the lower end of the ried on a shaft 17, and which engages a similar wheel or pinion l8, journaled in the center of the spider, and which carries on an extension or neck 19 radiating arms 20, that come in contact with the screen. The shaft 17 is journaled in sockets at 21 and 22 at the upper edge of the cylinder 5, and is rotated by a crank or handle 23, by which the bevel gear-wheel 16 is rotated, which in turn coinmunicates motion to the pinion 18, and consequently the radiating arms, and thereby forces the flour through the screen.

In the lower portion of the bin or vessel is a shaft or rod 24, having bearing in the sides of the vessel at 25 and 26, and having a central crank portion 27, to which is loosely connected at 28 a conical cut-off 29, that when the shaft 24 is turned to lower it rests over and closes the neck 4 and forms a cutoff to prevent flour from dropping into the sitter when desired. The shaft 2 1- is provided at one end outside of the vessel with a crank or handle 30, by means of which the cut ofi may be raised to the position shown by dotted lines in Fig. II, and when desired can be so cured in this position by means of a hook 31.

The whole device is secured. to the wall ,or other support at a suitable height by means of rods 32, (one on each side,) connected to the upper part of the vessel by thumb-screws 33 and to the wall by an eyebolt 34 and by rods 35, (one on each side,) connected by thumb-screws 35 to the lower part of the vessel and to the wall by hooks 36, formed on the ends of the rods, which engage in screweyes37.

By means of the above-described arrangement I am enabled to hang my device high enough for convenience in use, and when it is to be filled I can lower it to a convenient height, as by disengaging the hooks 36 from the eyes 37 the device is allowed to drop to the position shown in Fig. VII.

In Fig. VIII, Ihave shown a modified form of supporting device, differing from that form shown in Figsl, II, and VII in having one V- shaped rod 41 on each side in place of the two rods 32 and 35. These V-shaped rods 41 have an eye formed in the center, through which they are attached to the vessel by means of thumb-screws l0, and are attached to the wall by eyebolts' 34 and hooks 36, en gaging, in eyes 37, as in the main form. It is obvious that this modified form of supporting rod will operate and allow the vessel to be lowered by disengaging'the hooks 36 from eyes 37 in substantially the same manner as the main form.

In Fig. IX,I have shown a modification of the sitter, in which the screenis of concave form and the agitator is made of Wire twisted together at the ends and expanded in the center, the twisted ends forming an axle for supporting the agitator, and one end extends outside of the cylinder and forms a crank or handle.

I claim as my invention-- 1. In a flour bin and sitter, the combina tion of the receptacle, a sitting device located at the lower end of the receptacle, a crank roeleshaft passing through the receptacle, and a conicalcut-off loosely suspended from the crank of the shaft, substantially as and for the purpose set forth.

2. In combination with a flour-bin or similar receptacle, a supporting device consisting of rods pivotally connected to the receptacle and support and rods pivotally connected to the receptacle and detachably connected to the support, whereby the receptacle may be held either in raised or lowered position, substantially as herein set forth.

3. In combination with a flour-bin or similar receptacle, a supporting-fra1ne consisting of rods pivotally connecting the receptacle With the support and detachably connected to the support, whereby the receptacle can be held in raised or lowered position, substantially as herein set forth.

JOHN N. BEALL.

In presence of THOMAS KNIGHT, A. M. EBERSOLE.
