UNITED STATES PATENT OFFICE.
ROBERT J. MANN, OF ST. LOUIS, MISSOURI.
IMPROVEMENT IN SIEVES.
Specification forming part of Letters Patent No. 154,800, dated September 8, 1874; application filed February 2, 1874.
To all whom it may concern.-
Be it known that I, ROBERT J. MANN, of St. Louis, in the county of St. Louis and State of Missouri, have invented a new and valuable Improvement in Sieves; and I do hereby declare that the following is a full, clear, and
exact description of the construction and operation of the same, reference being had to the annexed drawing, making a partof this specification, and to the letters and figures of reference marked thereon.
Figure 1 of the drawings is a representation of my wire-cloth. Fig. 2 is a sectional viewof my sieve. Fig. 3 is an enlarged detail, showing groove, 8w. 7
This invention has relation to'the construction of sieves having metallic rims and it consists in the manner of fastening the wire-cloth to the rim by clamping it in a fold, forming the base, and soldering the angle within a groove swagedin the rim, as hereinafter described and claimed.
It is apparent that a sieve becomes useless as soon as a separation between the wire-cloth and rim takes place at any point of its circumference. In the ordinary methods of se-' curing the wire-cloth this is constantly liable to occur on account of the pressure upon the wire-cloth when using the sieve.
The object of this invention is to secure the wire-cloth firmly at every point of its edge to the rim in a lasting manner.
In the accompanying drawing, the letter A indicates the metallic rim,.in which is swaged a groove, 11, parallel with its bottom edge. 0 designates the wire-cloth, cut suflicientlylarge for its edge to extend within the fold below the groove b. The wire-cloth is then fastened in the groove by the application of solder, d, which fills the groove and at the same time forms a stout metallic union to the meshes of the wire-cloth.
An examination of this fastening will show that it is very secure. The groove afl'ords a firm hold to the solder, and this in turn is so intimately looped in and connected with the meshes just above the edge of the wire-cloth that it is impossible to separate the two by ordinary use.
What I claim as my invention, and desire to secure by Letters Patent, is
The sieve A, constructed with a groove, '1), and fold d for holding the wirecloth, and hav ing the wire-cloth soldered in the groove b, as described.
ROBERT J. MANN.
