PROVISIONAL SPECIFICATION.
Improvements in Middlings Purifiers, and Meal and Flour
Dressing Machines.
I LOUIS HAROLD NEAVE of Bicton Mills Fordingbridge, in the County of
Hampshire, Miller do hereby declare the nature of this invention to be as
follows:-
The main object is to provide improved apparatus for collecting and removing the
dust or floating particles from above the sieves of purifiers or meal & flour dressing
machines.
The invention consists essentially in the combination of a series of travelling
scoops with a freely suspended brush. The said scoops are preferably carried by
endless chains passing over pulleys at each end of the purifier and are so disposed
as to intermittently cut off the exhaust, whilst the brush is suspended from the
axle of one of the pulleys and is provided with a balance weight or weights to hold
it in position.
In some cases two brushes are used to remove the dust from both ends of the
purifier. A series of endless chains or their equivalents and scoops may be used if
desired.

Improvements in Middlings Purifiers, and Meal and Flour
Dressing Machines.
I LOUIS HAROLD NEAVE, of Bicton Mills, Fordingbridge, in the County of
Hampshire, 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 :-
The main object is to provide improved apparatus for collecting and removing the
dust or floating particles from above the sieves of purifiers or meal and flour dressing
machines.
The invention consists essentially in the combination of a series of travelling
scoops with a freely suspended brush. The said scoops are preferably carried by
endless chains passing over pulleys at each end of the purifier and are so disposed as
to intermittently cut off the exhaust. The brush is suspended from the axle of one
of the pulleys and is provided with a balance weight or weights to hold it in
position.
In some cases two brushes are used to remove the dust from both ends of the
purifier. A series of endless chains or their equivalent and scoops may be used if
desired.
DESCRIPTION OF THE DRAWINGS.
Fig. 1 is a longitudinal vertical section, and Fig. 2 a transverse vertical section of
my improved dust collector applied to a middlings purifier. a is the usual purifier
case, exhaust fan, c sieve, d cover with longitudinal slots or openings e through

cross bars. chain wheels carried on shafts .g. The chain-wheel receives
motion by gear which may be of any usual or suitable kind. The axle g of the
wheels carried in the usual adjustable benings to allow of the chains being kept
properly stretched. i, chains which rest during the lower portion of their travel on
guiles secured to the case a scoops attached to the chains, and so disposed as to
intermittently close the openings whilst travelling along from one end of the
apparatus to the other. In this was the upward current of air being arrested
periodically for a short time the dust which has passed through the openings, readily
settles and is deposited on the scoops & and also on the cover d from which it is
removed by the said semops. I brush carrie freely by the sleeve m
shaft weight attached to the sleeve m for the purpose of maintaining the
brush 7 in position during the rotation of the shaft g. The said brush removes
adering dust from the inside of the scoops & and causes it to fall into the
trough whence it is removed by the creeper conveyor or worm p.
brush fixed

on the
to the trangho for the purpose of removing dust from the outside of the scoops
and depositing it in the said trough o.
k
There may be a brush and trough at each end of the machine and two or more
sets of scoop- may be placed over each other. The cover d may also be
di-pensed with, but I prefer the arrangement shown.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is :
First. The combination of travelling scoops with middlings purifiers for the
purpose set forth.
Second. The combination in middlings purifiers of travelling scoops with a freely
suspended brusb substantially as set forth.
Third. The combination in millings purifiers of travelling scoops and a slotted
cover or its equivalent for the purpose set forth.
Fourth. Dust collectors for middling purifiers substantially as set forth.

page_text: Referring to Figs. 4 and 4^. In this case also the loose tube or sleeve C is
extended above the top of the bolster B and is provided with a friction piece or
thimble c' which comes in contact with the spindle A above the bolster and receives
motion therefrom. The sleeve C rests upon a ball or balls F inserted between the
thimble piece c' and the top end of the bolster and which rest in a groove on the
top of the bolster. If desired the ball or balls inserted between the top end of
the bolster and the sleeve may be caused to come in contact with the spindle also.
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, we declare that what
we claim is :-
1. The combination with the spindle A and bolster B of a loose sleeve which
loosely fits inside the bobbin and over the bolster and receives a rotary movement
direct from the spindle by means of balls or frictional contact therewith substantially
as described.
2. In machines for spinning and doubling the combination of the spindle A, the
long bolster or collar B, the loose sleeve or tube C which fits loosely upon the
bolster, and the balls F which extend through holes in the bolster into contact with
the spindle and upon which the loose sleeve rests substantially as described.
3. The combined construction and arrangement of spindle, bolster, and sleeve
whereby the latter receives the desired movement substantially as described and
shown with reference to either of the Figs. 1 to 5 of the drawings.
