VUMI LEIE DI DUITIATION
A New or Improved Flour Sifter.
I, DONALD MCKENZIE, of 261-2 South Water Street Cleveland, in the
County of Cuyahoga, and State of Ohio, United States of America, Manufacturer,
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, that is to say :-
My invention relates to an improved flour sifter of the class which are carried
and manipulated by the use of one hand only.
The object of my improvement is to combine simplicity and convenience with
a device expedient and unique in operation.
That the invention may be fully understood and seen, reference is had to the
following Specification and the accompanying drawings in which
Figure 1 represents a plan view of said sifter, and Figure 2 is a part side and
part sectional view of the same.
Like letters of reference denote like parts in the drawings and Specification.
The flour sifter above referred to substantially consists of the following parts
viz. the bucket A, screen bottom C, the handle D and sweeper or agitator E.
The bucket A is preferably cylindrical in form, the upper side (a) being oblique,
while the lower side (b) is straight or square. The purpose of the side (a) being
oblique is to facilitate the filling of said bucket or sifter proper. The screen C
comprises the bottom of said bucket and is held secure in the manner as shown
at (f) Fig. 2. Placed in close proximity to said screen is the sweeper E, the latter
is attached to the rod (9) which extends transversely over and through the
bucket A as seen in Figs. 1 and 2.
The handle D, which is hinged at (h) may be of any suitable form or material,
and has depending from the under side thereof the arm (i), which engages the
eyelet g of the rod g. The connection of said arm and rod however may be
attained in different manner or means without departing from the nature of my
invention. The modus operandi of the above said sifter is as effectual as unique.
The bucket being filled, it is a simple forward and downward exertion of the hand
or arm or movement of the wrist only which accomplishes a tossing of the bucket,
that is exercising the wrist in vertical direction causes the bucket to swing upon
its horizontal hinge, and quickly repeated motious will result in rebounding effects
of the handle upon said bucket; the screen bottom thereby vibrates under the
Sweeper E, which causes an agitation of the flour as the sweeper is restrained
from following the movements of the bucket owing to the connection of the arm
and rod see Fig. 2.
The dotted line X indicates the extent to which the handle can be withdrawn
or tilted for the sweeper to slide over the entire face of the screen, and
comparatively but few exertions in about the manner as above referred to suffice
to empty the bucket of the contents to be sifted through the screen C.
Having now particularly described and ascertained the nature of this invention
and in what manner the same is to be performed, I declare that what I
claim is :-
First. In a flour sifter the handle having a horizontal hinge in common with
the upper rear side of the bucket part thereof, to admit of tossing said bucket by
said handle, and the depending arm of said handle in engagement with the eye
of the guide rod of the sweeper constructed and arranged substantially as shown
and for the purpose described.

page_text: Second. In a flour sifter the combination with the bucket, screen and sweeper
thereof, of a handle having a horizontally arranged, hinged connection with and
near the rear top edge of said bucket, and an arm depending from said handle for
connection with the rod of the sweeper, to restrain said sweeper when the hinged
bucket is tossed by said handle, constructed and arranged substantially as and for
the purpose set forth.
