GEORGE KIRCIIGPABER, OF ST. LAlVRENCE, DAKOTA TERRITORY.

FLOUR-CHEST.

SPECIFICATION forming part of Letters LPatent No. 398,736, dated February 26, 1889.

Application filed April 16, 1888.

Be it known that I, GEORGE KIRCHGRABER, a citizen of the United States, residing at St. Lawrence, in the county of Hand and Territory of Dakota, have invented certain new and useful Improvements in Flour-Chests; and I do declare the following to be a full, clear, and exact description of the invention, such as i will enable others skilled in the art to which it appertains to make and use the same,referenee 1 being had to the accompanying drawings, 1 and to the letters and figures of reference marked thereon, which form a partof this specification.

The special object of the invention is to make the sieve and its supports so that it may be put in and taken out without interfering i with the flexible rubber which extends from the hopper-hole nearly or quite to the bottom l of the sieve, the raised pocket at one end prc- Q venting the sieve from being drawn back and E out of the chest.

Figure 1 of the drawings is a vertical section; 2, a horizontal section on line m, Fig. l; Fig. '3, a vertical section showing the sieve in a position to be removed; Fig. 4', an 1 end view, partly in section; Fig. 5, a detail perspective view of the sieve.

In the drawings, A represents the chest, and B the hopper, with a hole, I), surrounded by the rubber I), which is flexible, and projects nearly to the bottom of the sieve, so as to guide the flour down to the sicv? without spreading it laterally thereon.

I is the door through which the sieve is partly drawn back before it is taken out. The sieve is made of a woven-wire fabric, I), 1 on the bottom and sides, said fabric being brought up over the ends of the side pieces, G C, and extendedinwardly forsomedistance to prevent the escape over the ends of the impurities lodging in the pockets 0 c. On the bottom of the rabbeted sides C C are i made fast the cross-pieces F F, which project beyond them and slide on the cleats G G, made fast to the sides of the chest A, at the same height and directly opposite each other. Two cleats are on each side with an interme diate open space through which the ends of l the cross-pieces F may pass.

E is the rod by which the sieve is moved horizontally back and forth in order to make the flour pass therethrough.

The chest is used as follows: The flour, hav- To all whom it may COILOCT'IZ. I i s Serial No. 270,769. (No model.)

ing been emptied from the bag or other receptacle into the chest, finds its way by its own gravity through hopper and rubber spout or guide to the sieve, upon which the lower end of the column rests. hen the cook or baker wishes, the sieve is reciprocated until as much as is needed has been deprived of its impurities, which are caught in the pockets. The drawer is then removed to pour the flourinto some other receptacle, or the flour is taken out of the drawer without the removal of the latter by a scoop. After the flour has been all used and the chest is empty, the drawer is first removed and then the sieve, so that the impurities may be emptied from the pockets.

The sieve cannot be inserted in place or removed therefrom by a horizontal movement on account of the projecting rubber Z) and the elevation of the ends 0 0' above the bottom of sieve; hence the sieve is first drawn to the position shown in Fig. 3 of the drawings, and then carried down to the position shown in dotted lines, when it is drawn out entirely. This operation is reversed in order to put the sieve into place, so that the cross pieces F shall rest on the cleats G. In both operations the drawer II is first taken out.

I am aware that the chest with top-hinged door and the hopper with projecting rubber about the hole Z1 thereof are old; also, that sieves have been used with pockets; but

\Vhat I claim as new, and desire to protect by Letters Patent, is-

1. A flour-chest s'eve consisting of the side pieces, C C, covered at the ends by woven wire, and the cross-pieces F I, supporting a bottom of woven wire, pockets co being thus formed to extend above and below the sievebottom.

2. The combination of a flour-chest having side cleats, G G, and a sieve having crosspieces F F, extended to rest on them, the cleats and cross-pieces on each side being separated by an intervening space, as shown, whereby the sieve maybe put in or taken out, as described.

In testimony whereof I a div my signature in presence of two witnesses.

GEORGE KIRIIIGRA BER.
