Mechanic and WILLIAM NAPIER 35 Royds Street, Stockport Road, Manchester,
Mechanic do hereby declare the nature of this invention to be as follows:-
A flapper fixed longitudinally on a textile machine and extending the whole
ength of the frame; the said flapper being attached to the frame by a continuous
lexible hinge and actuated either by hand or power causing a draft which blows off
he frame any dust and the like from the material operated on.

COMPLETE SPECIFICATION.
An Improved Means for the Expulsion of Dust and the like
Produced in Textile Machinery.
We JOSEPH DAVIES of 43 Gladstone Street, Clowes Street, West Gorton,
Manchester, in the County of Lancaster, Mechanic and WILLIAM NAPIER of
35 Royds Street Stockport Road, Manchester, Mechanic, 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 and
accompanying drawings:-
:―
Our invention has for its object to. check the accumulation of dust or fluff on
parts of machines employed in the preparation, spinning, manufacture, or treatment
of yarn and textile materials or goods. We apply flappers or air wafters which
are lifted at, intervals and allowed to fall the currents of air created by the falling
flappers wafting or blowing the dust or fluff from the surfaces or parts which are
intended to be kept free from accumulation.
In order that our invention may be clearly understood we will describe the same
more fully with reference to the accompanying drawing which represents so
much of a spinning frame as is necessary to the sufficient illustration of our
invention.
C
In the said drawing a is a cross section of the top rail of a spinning frame, b is
one of the ordinary roller stands and c is one of our so termed "flappers." This
flapper consists of a board or other material which is hinged at d to the top board e
of the frame. The flapper may extend the length of the frame or nearly so but
we find it more convenient in practice to make the flapper in two or more lengths
or sections so as to avoid having the board constituting the flapper of an excessive
length. When the flapper is raised so as to turn upon its fulcrum at d--say into
the position indicated by the dotted lines c-and suddenly released so that it can
quickly fall back into the horizontal position the flapper wafts a current of air over
the surfaces of the beam a and of the ordinary thread guide board f such air
current blowing away the dust and fluff as will be readily understood. This lifting
of the flapper may be effected by hand or by self-acting apparatus receiving motion
from a suitable part of the mechanism of the frame. In the example the flapper
is lifted by apparatus receiving motion from the back roller shaft y.
A pinion
upon this shaft gears with a spur wheel which is carried by a bracket or stand i
which is secured to the rail a and a second pinion h¹ attached to the wheel h gears
with a second wheel k which carries a stud k¹. It will be seen that the wheel

page_text: will be caused to revolve slowly as compared with the back roller shaft. In each
revolution the stud k¹ passes below a finger which is attached to the flapper and
by acting upon such finger raises the flapper. In the drawing the said stud appears
as when commencing to lift the flapper. When the flapper has been raised into
the position indicated by the dotted lines or thereabouts the stud leaves the finger
and the flapper is allowed to fall. In the case of a long flapper we may employ
two or more sets of apparatus acting upon the flapper at two or more points to raise
the flapper. A flexible hinge made of leather or other suitable material might
take the place of the metal hinge which appears at d. The flapper or two or
more flappers might be attached to a rock shaft and such shaft might be acted upon
to raise the flapper or flappers as for example-a stud upon a wheel or disc or a
wiper might act upon a lever fixed upon the rock shaft. In place of the flapper
moving partly around a centre or fulcrum when being raised it might be lifted
bodily remaining during its movements about parallel with the surface from which
it is lifted and being dropped back upon such surface so as to waft air in both
directions right and left. We do not confine ourselves to the use of a flapper
board as the flapper might consist of a frame covered with cloth or with a suitable
material. If considered to be desirable the falling of the flapper might be assisted
by the action of a spring or load. Any suitable means may be employed for raising
the flapper.
Although we have illustrated our invention in connection with a
spinning frame it must be understood that our invention may be applied to roving
machines, mules, looms, and other textile machines. In the cases of mules we
might arrange for the flappers to be acted upon by parts mounted upon the fixed
framing so that the flappers would be lifted at each draw or run home of the
carriage.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
1. The method of and means for wafting off dust and fluff from parts of textile
machinery substantially as set forth and indicated.
2. A hinged flapper adapted to be lifted and released so as to create a current
or currents of air in falling substantially as and for the purpose set forth and
indicated.
3. As applied to textile machinery an air wafter in combination with means for
lifting such air wafter and for releasing it so that it may fall suddenly substantially
as and for the purpose set forth.
4. The flapper c mounted and operated upon substantially as and for the purpose
set forth.
