ASH SIFTER.

Application filed April 23, 1924. Serial No. 708,464.

, State of Ohio, have invented a new and useful Ash Sifter, of which the following is a specification.

The present invention has reference to ash sifters, the primary object of the invention being to provide an ash sifter so constructed that the dust present incident to the sifting operation will be trapped and confined within the body portion of the sifter.

Another important object of the invention is to provide means whereby the coal recovered by the sifting operation may be readily and easily dumped into acoal receiving bin, forming a part of the sifter, eliminating the necessity of opening the sifter to accomplish the dumping.

lVith the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the com bination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, may be made within the scope of what is claimed, with out departing from the spirit of the inven tion.

Referring to the drawing: Figure 1 is a front elevational view of sifter constructed in accordance with the invention.

Figure 2 is a longitudinal sectional view through the sifter, and

Figure 3 is an end elevational view of the sieving element.

Referring to the drawing in detail, the reference character 5 designates the body portion or housing of the sieve which may be of any desired construction but prefer ably formed with an upper curved wall 6 to conform to the contour of the sieving ele-- ment and present as few corners as possible to restrict the accumulation of dust.

The front and rear walls of the housing are formed with openings providing bearings for the shaft 7 that has its forward end formed into an operating handle 8. Mounted on this shaft is the sieving element indicated at 9, which sieving element is semi-cylindrical in formation and formed with suitable wire mesh material, the upper edges of the sieving element being braced by the bars 10 formed with openings through which the shaft 7 extends, and through which the sieving element may be secured to the shaft.

Closing the upper portion of the sieving element- 9 is a chute 11, which extends forwardly as clearly shown by Figure 1 of t-he drawing, so that the mouth thereof, when the member 9 is in its normal position, will be disposed adjacent to the opening in the forward wall of the housing, and which is closed by the closure 12. Thus it will be seen that when the closure 12 has been moved to its open position, the ashes to be sifted may be readily and easily dumped into the sieving element 9 through the chute 11.

Extending upwardly within the housing 5 and spaced from the front wall thereof, is a partitioning wall indicated at 13, which wall has its upper extremity terminating in spaced relation with the upper end of the housing providing a clearance for the sieving element.

This partitioning wall 13 divides the housing 5 into a forward coal receiving compartment 14, and an ash receiving compart-ment 15, each of which compartments is provided with a sliding door 15 that may be moved to their open positions and allow the material in the compartments to be removed therefrom.

In the operation of the device, it is obvious that when the material to be sifted is passed into the chute 11 from where it falls into the sieving element 9, the handle 8 is now operated to oscillate the sieving member 9 causing the fine particles of material to pass through the mesh thereof.

After the material has been properly sieved, the handle 8 may be moved to an upper position, bringing the chute 11 to a position, as shown in dotted lines in Figure 2 of the drawing, whereupon the coal or larger particles will fall from the seiving element 9 into the chute 11 from where it will be directed to the compartment 14.

I claim 1. A sieve including a housing, a partition dividing the housing into compartments, a shaft extending through the upper portion of the housing, a sieving element supported by the shaft, a chute housing in the upper portion of the sieving element, said chute adapted to direct material to the sieving element when the sieving ele-= ment is in its active position, and said chute adapted to receive material from the sieving element and deliver the material to one of the compartments when. the sieving element is in its inactive position.

2. A sieve including a housing, a horizontally disposed shaft in the upper portion of the housin a sieving member on the shaft and adapted to move therewith, a chute forming a housing from the upper portion of the sieving member, said housing having an'opening in the upper edge thereof, said chute adapted to lie in a position adjacent to the opening to receive material passed through the opening said chute adapted to receive material from the sieving memberand direct material to the housing when the sieving member is moved to an inverted position.

3. A sieve including a housing, a shaft extending through the upper portion of the housing, a semi-circular sieving member on the shaft, a chute for directing material to the sieving member, said chute being supported by the shaft, a handle for oscillating the shaft, and said chute adapted to receive material from the sieving member When the sievingmember is moved to an inverted position, and said chute adapted to deliver material to the housing.

In testimony that I claim the foregoing as my own, I have hereto aflixed my signature in the presence of two Witnesses.
