DUSTLESS FLOUR-CAN AND FLOUR-HOLDER Reissued Mar. 20, 1906'.

.To all whom it may concern:

Be it known that I, WILLIAM G. GADUE, a citizen of the United States, residing in the city of Burlington, in the county of Chittenden and State of Vermont, have invented a new and useful Improvement in Dustless Flour-Cans and Flour-Holders, of which the following is a specification.

My invention consists of a flour can and holder for household use where flour can be kept free from dust and other objectionable things, and when any is-wanted for use, ever so small or so .large a quantity, it can be sifted into any rece Y tacle desired. The can or holder is made o tin orother metal, holding from twenty to fifty pounds of flour, with no openings except at the top, which is closed by a cover. At the bottom a sieve is firmly soldered, with the edge of said siev'e; y Figurel isa vertical sectional view of the a slight ridge around 'jdevice n line` 1-1, Fi'g..2. Fig. 2 is a horizontal section of the same on line 2 2, Fig. 1. Fig. 3 isa perspective view of the agitator detached.

A is the cylindrical bod of the flour-holding can made of tin or ot er metal and supported by suitable legs, as shown in Fig. 1. The bottom E of the can (united to the body of the can by a lockfseam)'is dished and has in it a central circular opening, to which is applied a Wire-cloth sieve D, applied and sol-l dered to the outer face of the ottom E, so as to be below the portion e of the bottom, which borders the sieve, which portion is slightly raised above the sieve surface to support and form a bearing for the spokes of theV tator hereinafter described. The bottom, asV before said, is dished, the depth of dish or bevel being about one and one-half inches; The bottom around its inner border or rim is depressed as at af a, the de ression formin a shallow annular gutter a out half an inc Wide surrounding the metallic border of the bottom, which circumscribes the sieve-surface 1);,

B is a vertical shaft which passes through and is journaled in the coverG of the can and has attached loosely to its lower end the agitator C. The shaft at its extreme lower end passes. loosely through the sieve D and through a cross-bar D', In which it can revolve, and has on its screw-threaded lower vcarry all undesirable ends of t e spokes.

end below the cross-bar D a holding-nut d. The agitator O is loosely mounted on a squared portion of the shaft B, which passes through a correspondingly-shaped hole in the central strap c of the agitator, so that the agitator while rev lving with the shaft 'may have a slight rocking motion relatively thereto. The upper end of the shaft which projects above the cover G has detachably connected with it a crank K, by which it may be rotated.

The agitator consists curved spokes O', on the upturned ends of which the rim C is supported, the rim being broken away on the twov opposite sides of the agitator, as seen in Figs. 2 and 3 at c. The spokes C extend outwardly beyond the oint where the sieve ends and overlap an rest upon the metallic border e, which surrounds the sieve. The bent-up ends of the spokes support the rim C; of the agitator in a osition in which it will be about half an inc above the bottom, thus leaving ample room for lumps and all undesirable objects to be thrown out by the spokes as the agitator revolves. By the action of the spokes the lumps are carried outward beyond the sievesurface onto the border e, overlapped by the spokes, where they pass under the rim into t th of the rim C and the e gutter a., this being greatly facilitated by e two sides of the away, as shown at c', Fi agitator C is of cast-iron, t cast in one piece.

After a series of experiments it was found that the raising of the rim C of the agitator by the bent-up ends of the spokes and the breaking away of the same on opposite si des enabled the agitator to effectively act to objects outwardly beyond the sieve surface, discharging them under the rim and out where the sides are broken away into the gutter.

Fig. 3 shows how the rim C of is raised u from the bottom by the bent-up It was found after many experiments that this peculiar shape of the spokes-namely, bent up at their outer ends, so as to make about half an inch between the rim C of the agitator and the metallic border e around the outer edge of the sieve-was necessary in order to do good Work. When the agitator is in revolution,

agitator being broken s. 2 and 3. The e rim and spokes the agitator I IOO the action of the spokes is `to carry lumps and impurities outwardly beyond the sieve-surface D and onto the solid metallic border e, out u on which it can freely ass under the rim and there the refuse Wi l be kept.

It will be observed that the agitator rests by its spokes upon the metallic border e, which is slightly raised above the sieve-surface, so that the s okes have this border for a bearing and are tlius kept from touching the sieve, although the run very close to the same. The run C, eing raised up from the bottom by the bent-up ends of the spokes, makes room for the outward passage beneath it of the lumps and other impurities outwardly conveyed be ond the sleve area by the action of the spolies While the agitator 1s in revolution. The gutter a, which I rovide for catching these outWardly-impel ed impurities, is, as before said, half an inch or more in width; but this width can be varied as desired.

To use the device,rst put in the shaft B, with the agitator attached to its lower end by a loose `oint, and then put in the our. The cover is then put on, with the shaft B through the middle, and the crank K is fitted on the square up er end of the shaft. The device is now rea y for use and by rotation of the crank will deliver sifted flour 1n any uantity desired, the action of the agitator eing to carry all impurities putwardl beyond the sieve-surface and keep them t ere, so that Y none will ,ass througl the sieve. The, agitator, as a eady stated, bears upon the metallic raised border e around the sieve, and when a uantit of flour is put into the can the weig t of t e flour will prevent the agitator from moving with entire ease at first, but very soon the our will Work under the agitator between itand its annular bearingsurface, so as to lubricate the same, thus permitting its easy and free movement.

What I claim as m invention, and desire' to secure by Letters gatent, is-

1. A can having a dished bottom with a central opening therein, a screen closing said opening, that ortion ofthe bottom bordering the scr n being slightly raised above the surface of t e latter, in combination with an agitator consisting, of curved spokes which extend outwardly beyond the screen and take their bearing upon the slightly-raised border surrounding the same, and a rim supported in elevated position upon the upturned ends of said spokes, and actuating means for said agitator, substantially as and for the purposes hereinbefore set forth.

2. The agitator consisting of a rim, and curved spokes, provided with u turned ends which support said'rim, in com ination `with the can, the sieve or screen in the bottom of the can and an actuating-shaft loosely attached to said agitator substantially as and for the purposes hereinbefore set forth.

i 8. AThe agitator consisting of the curved s okes C provided with upturned ends, and t e rim C supported on said upturned ends, and broken away at c on opposite sides of the agitator, substantially as and for the purposes hereinbefore set forth.

4. The can A provided with a bottom having a slightly-raised border e encircling an opening therein, a gutter a surrounding said border and a screen ap lied to said opening, in combination Witht e agitator consisting of the spokes C extending outwardly beyond the screen and upon the border e, and the rim C sulpported upon the upturned ends of said spo es, and means'for actuating said agitator substantially as and for the pur poses set forth.
