PROVISIONAL SPECIFICATION.
Improvements in the Troughs or Trays Used in Purifiers for
Middlings and the like.
I, ERNEST REDLER, of Longaller Mills, Taunton, Somersetshire, Miller, do
hereby declare the nature of this invention to be as follows:-
This invention relates to a specially shaped tray or trough for use in purifiers
and is so formed with a straight part gradually curved round at the bottom: these
trays are set slantingly in the machine over the usual sieve, so that the end of the
bottom curve comes under the slantingly top of the next tray. The trays may be
set horizontally or diagonally, or in V form.

COMPLETE SPECIFICATION.
Improvements in the Troughs or Trays Used in Purifiers for
Middlings and the like.
I, ERNEST REDLER, of Longaller Mills, Taunton, Somersetshire, Miller, 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 :-
This invention for improvements in, or connected with trays used in flour
machinery refers to trays or troughs, of special section, and relative arrangement
one with another, sets of such trays being located above the series of purifiers
and the like. The trays are placed in their frames parallel to each other, but
extend across same at angles greater or less than right angles, and in some cases
the trays extend partly across the carrying frames to one angle, and then at a
suitable distance, or entirely across, at another angle, in contra-distinction to trays
which commouly extend at right angles to their frames, either transversely, or
longitudinally across same.
I will describe my invention by reference to the accompanying drawings wherein
Figure 1, is a sectional prospective view, taken transversely across several trays
constructed and relatively arranged according to my said invention. Figures 2
and 3, are diagrammatic plan views indicating such trays placed in sets: and
Figure 4, is a similar view shewing a somewhat varied arrangement.
Referring to Fig. 1, A, A, are the trays or troughs each formed with a straight
part A', gradually curving round at the bottom or lower part of the tray as at A³,
the said trays being arranged at a regular distance apart, parallel to one another,
and also set slantingly in the frame, that is, with the straight parts inclined to the
horizontal plane in such manner, that the edge of the curved lower part A', of one
tray comes vertically under the top edge of the straight part A¹, of the next tray,
as will be observed by reference to the vertical directing line marked B.
Trays A, A, of a section and relative arrangement as herein described, are
carried in suitable frames C, and are located above the sieves of purifiers, or the
like. In Figure 1, such a sieve D of a purifier is indicated below the trays A, A.
As before stated the trays A are to be arranged angularly across frames C, as
Plains 1

page_text: shewn at Figures 2 and 3, or may form varying angles across the frames as at
Figure 4. I would have it understood that I do not limit myself to the sizes or
proportions of the trays shewn in the drawings, nor to the pitch or distance apart
at which the trays are arranged, as these may be varied according to circumstances
without departing from my invention. By my invention I materially improve the
efficiency of machinery fitted with my improved trays arranged as described, both
in the results obtained and the economy of production by causing the material
treated to be more evenly subjected to the screening action."
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
―:
1. In flour machinery, the trays A, each having a straight part (such as A¹)
curving round at the bottom (as at A³) the said trays being arranged parallel to
each other, and having the straight parts (A') inclined, whereby the lower
part (A) of one tray, comes vertically under the top edge of the straight part of
the adjacent tray, all substantially as described and illustrated with reference to
the accompanying drawings.
2. In four machinery, the trays A each having a straight part A', curving
lower edges A, and arranged parallel to each other in vertically inclined positions,
and carried in sets in suitable frames located above the sieves of purifiers and the
like, the said trays extending across their frames at angles greater or less than
right angles, or partly across. Such frames at one angle, and for a suitable
distance or entirely across same at another or opposite angle all substantially as
described.
