IMPROVEMENT IN SIFTERS.

Specification forming part of Letters Patent No. 140,869, dated July 15,1873; application filed April 25,1873.

To all whom it may concem:

Be it known that I, ALFRED BARDELL, of Williamsburg, in the county of Kings and State of New York, have invented a new and useful Improvement in Sifters for Ashes, Flour, and other materials; and I do hereby declare the following to be a full, clear, and exact description thereof, which will enable those skilled in the art to make and use the same, reference being had to the accompanying drawing forming part of this specification, in which drawing- Figure I represents a vertical central section of my invention. Fig. 2 is a horizontal section of the same in the plane at m, Fig. 1. Fig. 3 is ainodification of the same.

Similar letters indicate corresponding parts.

This invention consists in the arrangement of a segmental lip, which projects over the flange on the body of the sieve, in combination with stops and with a handlethat inclines downward in such a manner that by the pressure of the hand on said handle the body of the sieve is pressed into the segmental lip, and by the contact of the handle with the stops the material on the sieve is agitated. The segmental lip and the stops are either secured directly to the sides of the barrel on which the sieve is placed, or they may be secured to aring that fits the top of the barrel. From the body of the sieve projects a conical flange downward into the barrel, so as to prevent the escape of dust.

In the drawing, the letter A designates the body of a sieve, B, which may be made of metal or any other suitable material. From this body projects a flange, a, which catches under a segmental lip, b, that is secured to the barrel 0, and to this barrel are also secured two stops, 0 0, Fig. 2, which limit the revolving motion of the sieve. To the outside of the body A is secured a handle, 1), which inclines downward, and which is situated opposite to the segmental lip b and between the stops 0 0, so that by the pressure of the hand on said handle the flange a of the body A is pressed into the segmental lip, and when the body is-revolved the handle strikes against the stops 0 0, and thereby the material on the sieve is agitated and turned over and the operation of sifting is materially facilitated. From the bottom edge of the body A projects a conical flange, E, down into the barrel G. This conical flange forms a guide for the sieve as the same is revolved, and it also serves to prevent the escape of dust, since, by the motion of said conical flange, a suction draft is produced which draws the fine dust toward the center of the sieve, and prevents it from escaping over the edge of the barrel. This conical flange may be elongated to project away down into the barrel, according to the material for which the sifter is to be used. The barrel (3 may be made of sheet metal, as shown in Fig. 1, or the body A may be fitted in a sheet-metal ring, 0, Fig.3, which is provided with the segmental lip b and with the stops, and which fits upon an ordinary wooden barrel.

My sifter can be used with advantage for sifting ashes, or for sifting flour, or any other material which requires to be sifted. When it is to be used for flour I prefer the construction shown in Fig. 3.

Dhe body A is provided with a cover, F, which fits tightly into the same, a gasket, 6, being interposed to produce a tight joint.

What I claim as new, and desire to secure by Letters Patent, is-

The body 0 having the segmental lip 12 and stops 0 c, in combination with the body A havin g the conical flange E, sieve B, flange a, and inclined handle D, substantially as described.

. ALFRED BARDELL.
