JOSEPH A. LOWE, OF GAINESVILLE, TEXAS.

FLOUR-SIEVE.

SPECIFICATION forming part of Letters Patent No. 263,547, dated August 29, 1882.

. Application filed July 15, 1882.

To all whom it may concern Be it known that I. JOSEPH A. LOWE, a citizen of the United States, and a resident of Gainesville,in the county ofOooke and State of Texas, have invented a new and valuable Improvement in Flour-Sieves; and 1 do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being bad to the annexed drawings, making a part of this specification, and to the letters and figures of reference marked thereon.

Figure l of the drawings is a vertical sectional view of my sieve. Fig. 2 is a top view ofthc same, and Fig. 3 is a detail sectional view.

This invention has relation to flour-sieves; and the novelty consists in the construction and arrangement of the upwardly-flaring outer wall,circularly creased around its middle part, and the inner more flattened conical guidewall, provided with the wire'cloth stretched v across its top and about its upper edge, said guide-wall being sprung into or secured to the crease of the outer wall, the latter extending downward to the level of the discharge of the guide-wall, all as hereinafter set forth.

In the accompanying drawings, the letter a designates the outer wall or rim portion of the sieve, which is made in upwardly-flaring form, and is creased around its middle part from the inside outward, as indicated at I). This rim portion or outer wall may be wired in the usual manner at one or both of its edges, and may be provided with a ring or handle.

0 represents an inner conical guide-wall, the inclination of which is greater than that ofthe outer wall, a. It is therefore more flattened in form, converging more rapidly to its dischargeopening cl. The outer rim, 6, ofthis guide-wall is bent over and rounded downward, and to it is attached the marginal portion of the wire cloth or sieve disk 9, which is stretched across (No model.)

the top of the guide-wall. The depth of this guide-wall is about equal to that of the lower part of the outer wall, a, below the crease b, and said guide-wall is designed to be equal in diameter to that of the wall a at the crease, so that the edge e of the guide-wall, with the overlapping margin of the wire-cloth, can be sprung into the crease, and will be held therein by the elasticity of the parts. A more secure fastening can be efl'ected, if desired, by soldering the edge of the guide-wall into the crease. The guide-wall c is entirely below the wire-cloth, and serves to guide the flour rubbed through the sieve downward and inward to its small discharge-opening 07, so that it can be more accurately directed in its deposit than it the opening were as large as that of the outer wall, a. The broad rim wall extending down to the level of the cone discharge affords a support to the sieve, forms a guard to prevent somewhat the escape of flour-dust laterally, and facilitates materially the manipulation of the sieve.

Having described this invention, what I claim, and desire to secure by Letters Patent, 1s

A flour-sieve having the upwardly-flaring outer wall, circularly creased around its middle part, and the inner more flattened conical guide-wall, provided with the wire cloth stretched across its top and about its upper edge, said guide-wall being sprung into or secured to the crease of the outer wall, the latter extending downward to the level of the discharge of the guide-wall, substantially as specified.

In testimony that I claim the above I have hereunto subscribed my name in the presence of two witnesses.

JOSEPH ALFRED LOWE.
