PROVISIONAL SPECIFICATION.
Improvements in Sieves, Riddles, Drying-trays, and similar
Apparatus.
I, JAMES STANSFIELD, of Todmorden, in the County of York, Asphalte Manu-
facturer, do hereby declare the nature of this Invention to be as follows:-
It consists in forming the wire mesh or perforated metal of which the sieves or
other similar apparatus are made with a strong wire border which fits into a groove
formed in or near the lower edge of the wooden frame, or upon a projection formed
in or near the same position.
By this means I do away with the perforations in the wooden sides which so
greatly weaken them and enable fresh frames to be readily fitted to the sieves or other
similar apparatus when the old frames wear out or vice versa.

COMPLETE SPECIFICATION.
Improvements in Sieves, Riddles, Drying-trays, and similar
Apparatus.
I, JAMES STANSFIELD, of Todmorden, in the County of York, Asphalte Manu-
facturer, do hereby declare the nature of this Invention and in what manner the
same is to be performed, to be particularly described and ascertained in and by the
following statement :—
It consists in forming the wire mesh, or perforated metal of which the sieves or
other similar apparatus are made, with a strong wire border which fits into a groove
formed in or near the lower edge of the wooden frame or upon a projection formed
or left in the moulding or planing of the wooden frame, in or near the same position.
By this means I do away with the perforations in the wooden sides which so
greatly weaken them, and enable fresh frames to be readily fitted to the sieves or other
similar apparatus when the old frames wear out or vice-versa.
In order that the foregoing may be better understood I send herewith a sheet of
Drawings in which Figs. 1 and 2 are sections of parts, of wooden framed sieves,
fitted according to my invention.
In both Figs. a indicates the wooden frame, b the strong wire surrounding the
mesh of the sieve, c the groove, and in Fig. 2 d the projection, left on the frame in
moulding or planing.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is:
-
1st. In sieves, riddles, drying trays and similar apparatus, a wire edged mesh, in
combination with an internal annular groove, at or near the lower edge, of the
wooden frame, substantially as described and shown hereinbefore, and in the
accompanying drawings, for the purpose set forth.
2nd. In sieves, riddles, drying trays and similar apparatus, a wire edged mesh, in
combination with an internal annular groove and projection, at or near the lower edge
of the wooden frame, substantially as described and shown hereinbefore, and in the
accompanying drawings, for the purpose set forth.

page_text: 3rd. In a wooden frame for sieves, riddles, drying-trays and similar apparatus, an
internal annular groove, or an internal annular groove and projection, at or near its
lower edge, substantially as described and shown hereinbefore, and in the accompanying
drawings, for the purpose set forth.
