SIFTER.

SPECIFICATION forming part of'I..etters Patent No. 544,256, dated August 6, 1895.

Application led April lI 1895. Serial No. 544,085. (No model.)

To all whom t may concern;

Be it known that l, FRANK ALBERT IDDINGS, of-Warren, in the county of Trumbull and State of Ohio, have invented certain new and useful Improvements in Sitters; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.V

This invention contemplates certain new and useful improvements in sifters, by means of which flour and other substances canbe quickly and eifectively sifted.

The object of the invention is to provide a simple and inexpensive sifter of this character which shall be simple in construction, inexpensive, durable, and capable of easy operation.

A further object is to provide a receiving pan or drawer for the sifted substances, by which the amount or quantity of the contents can be readily ascertained.

To these ends the invention comprises the novel features of construction, and also the d etail, combinatiomand'arran gement of parts, substantially as hereinafter fullyset forth, and particularly pointed out in the claims.

In the accompanying drawings, Figure 1 is a vertical sectional View of my improved sifter. Fig. 2 is an enlarged vertical sectional view of the inclined bottom. Fig. 3 is a plan View of the sitter-Wheel. Fig. 4 is a detail.

Referring to the drawings, A designates the can or receptacle, which is preferably cylindrical and may be of any desired capacity. a is the cover therefor.

B is an inclined false bottom ot' approximately V shape in cross-section, its upper peripheral edge being secured to-the receptacle A at such a point as to leave a lower space to accommodate a pan or drawer b, which is inserted through an opening in the receptacle and rests upon the bottom of the latter.

The false bottom B has, preferably, a centrally-arranged opening and a surrounding depending angular flange b. Attached to this angular flange is a sieve b2. The pan or drawer h has its sides b3 made with corrugations, which latter are of such width or distances apart as to determine the quantityof thecontents. The outer end of this drawer conforms to the shape of the receptacle A.

C is the sifting-wheel designed to revolve within the depending flange b of false bottom B, directly over the sieve, a lugd serving to hold the wheel in place, said lug projecting over the rim of the wheel. From the upper side of this Wheel extends a short lug d',

to which is connected one end of a flexible shaft d2, the other end thereof being secured to the inner end of a short shaft cl3, which is passed through a tubular sleeve or bearing d4, fitted to the side of the receptacle. To the outer end of this short shaft cl3 is secured a crank d5. The flexible shaft d2 is preferably formed of a single coiled wire, and the short shaft d3 has a beveled collar and a recess d'5, in which tits the outer end of the wire, whereby a firm union is secured. By turning the .crank the sifting-wheel is caused to rotate and thel flour or other substance which is directed onto the sieve by the inclination of the false bottom is forced through said sieve and received by the pan or drawer. By employing a flexible shaft and extending it in -a curved plane up'into land above the false bottom it serves in part to agitate the flour, and the latter being directed by the inclined bottom falls onto the sieve and is .readily sifted by the turning of the Wheel. After the sifting is completed, the quantity o f the flour contained in the pan or drawer can be readily ascertained by the alignment thereof with the corrugations in the side of vthe pan.

A sifter thus constructed is extremely simple and inexpensive and not liable to readil5 get out of order.

I claim as my invention- 1. In a sifter having an inclined false-bottom provided with a central opening, a sieve within said opening, a sifting wheel above said sieve, a retaining lug projecting from said false-bottom above said sifting wheel and a flexible shaft connected to said wheel and extended upwardly above said false-bottom and provided with an operating handle, substantially as set forth.

2. The herein described improved sitter comprising the can or receptacle having a lower opening, a pan or drawer extended through said opening and having its sides corrugated horizontally, an inclined false-bottom above said pan or drawer having alower central opening, a sieve within said opening, a

sifting wheel over said sieve having a central lng, a retaining lug projecting from said false-bottom above said sifting-wheel a [lexible shaft connected at its lower end to said former lng and having at its upper end a short shaft, a sleeve or bearing for the latter secured to the side of said can or receptacle, and a crank-handle connected to said short shaft, substantially as set forth.

3. A sitter having a can or receptacle, a hollow bearing or bushing attached tothe side thereof, a sieve or screen, a wheel over the latter, a short shaft fitted in said hearing or bushing and having a collar thereon, provided with a recess, an operating handle on the outer end of said short shaft, and a flexible shaft consisting of a coiled wire having one end secured in said recess of said collars and at its other end to said Wheel, substantially as set forth.

In testimony whereof I have signed this specification in the presence of two subscribing Witnesses.

FRANK ALBERT IDDINGS.
