PROVISIONAL SPECIFICATION.
Improvements in and applicable to Apparatus for Purifying Meal
and Flour.
I, THOMAS ARTHUR RIGBY, of Frodsham Bridge, in the County of Chester,
Miller, do hereby declare the nature of this invention to be as follows:-
--
My invention relates to the class of purifiers in each of which a vibrating sieve
and current of air are used and employed.
Heretofore as means for collecting the stive or fuzzy matter removed in the
current of air woven fabrics and troughs have been used. These are inefficient and
defective.
To make purifiers more efficient, more simple and less costly are the main objects
of my invention.
In constructing purifiers under my invention 1 take a frame, connections, vibrating
screen and fan or air moving apparatus of any usual or suitable kind, and place in
combination therewith (or apply to existing purifiers as hereinbefore set forth)
corrugated plates of metal or other material having in the raised portions of the
corrugations elongated or other openings. It is through these openings the stive or
fuzzy matter is drawn and such stive or fuzzy matter falls from the air current into
the hollows of the corrugations and is removed by brushes or otherwise. By
preference I place the corrugated metal with the corrugations lengthwise of the
machine and inclined towards the tail. I remove the deposited matter from the
corrugations by means of brushes or by giving vibratory motion to the said corru-
gated metal.
A further part of my invention consists in placing over the elongated or other
openings hoods to deflect the stive into the troughs of the corrugated platos.
Deted this 2nd day of May 1890.

same is to be performed, to be particularly described and ascertained in and by the
following statement :-

DESCRIPTION OF THE DRAWINGS.
Fig. 1 is a transverse section and Fig. 2 a plan of a purifier having my improve-
ments. is the screen or sieve frame suspended and caused to vibrate in any usual
Inanner. is the silk, e, the exhaust fan. is a corrugated plate attached to the
screen or sieve frame some distance above the sill, and vibrating therewith. d'are
elongated openings in the raised portions of the corrugations through which the
stive and fuzzy matter is drawn. The corrugations rim from front to back of the
screen or sieve, and are inclined so that the stive and fuzzy matter which fall.
into the corrugations, is by the vibration of the inclined corrugated plate, cause 1
to travel towards and be delivered at the tail of the purifier.
If desired, hooils as shown at may be fixed to the corrugated plate, or as shown
at to the main frame y of the purifier, for the purpose of deflecting the stive into
the troughs.
Fig. 3 is a longitudinal, and Fig. 4, a transverse section of a purifier in which the
corrugated plate d is secured to the main frame of the purifier so as to he
stationary and where he ashes & carried by endless bands and operated in any
snitable way are usul,,„weep stive from the bottoms of the corrugations,
Having now particularly described and ascertained the nature of my said inven-
tion, and in what mauner the same is to be performed, I declare that what |
claim is :-
First. In apparatus for purifying meal and flour-the combination of a vibrating
screen with a corrugated plate of metal aflixed thereto and vibrating therewith,
having apertures in the raised portions of the corrugations substantially as set
forth.
Second. In apparatus for purifying meal and flour, the combination of a vibrating
screen with a corrugated perforated plate affixed to the frame of the purifier anil
provided with brushes, substantially as and for the purpose set forth.
Third. In apparatus for purifying meal and flour, the combination of a vibrating
screen and perforated corrugated plate with hoods, substantially as and for the
purpose set forth.
