AVSH-SIFT'ER.

To all whom it may concern:

' Be it known that I, ABE ARENSON, a

citizen of the United States, and a resident inclosing housing within which an inclined 1 screen structure is provided onto which'the'" ashes are shoveled. However, in such structures the screen is stationary and whatever ashes fall through the screen openings must do so during travel of the mass from the top of the screen to the bottom. No means are therefore provided for agitating the mass on the screen and in most devices a considerable amount of ash is delivered with the coal in the coal receiving receptacle. The main object of my invention is therefore to provide means for oscillating the screen structure within the housing to insure thorough sifting out of the ash and delivery of only the unburned coal particles to the coal receptacle.

On the accompanying drawing I show a structure embodying the features of my invention. In these drawings Figure 1 is a plan View,

Fig. 2 is a side elevational view, and

Fig. 3 is a sectional view on plane 33, Fig. 1.

The housing of my improved structure is preferably of sheet metal and comprises a lower substantially vertically extending section 10 forming a compartment for receiving the sifted out ashes, and the upper downwardly inclined section 11 forming a run-way for coal and ash mixture to be sifted. At the upper end of this run-way a hopper 12 is rovided and the lower end of the run-way 1s adapted to be closed by a door 13 hinged at its loweredge to the front wall of the section 10, as indicated at 1 1. Between the run-way 11 and the ash receiving part 10 a screen structure 15 is interposed, the mass dumped into the hopper falling on and traveling alon the screen structure to separate the ashes rom the unburned coal particles. In order to permit agitation of the screen structure I pivot such 5,5 I'spei s nt Patented Mar. 11, 1919. 2 Application filed March 1, 1917, Serial 110i 151,663. Renewed January 21, 1919.

structure substantially mid-way thereof on a cross rod 16 supported by the'sides of the housing so that the screen structure may be oscillated, and to enable such oscillation to be readily accomplished from the exteriorof the housing I provide a handle bar 17 which is pivoted to one end of the screen and extends to the exterior of the housing through the slot 18 provided in the top wall there- 'of. Above the upper end of the screen structure a stop ledge 19 is provided and below the lower end of the screen a stop ledge 20 is provided, the screen normally resting against these stops to receive a charge of ashes to be sifted. After such charge the bar 17 is raised and lowered and the screen oscillated to thoroughly and completely separate the particles or ashes from the unburned coal. Such oscillation is limited by the stops 19 and 20 and the engagement of the upper end of the screen w1th the rear wall of the housing at 21. The door 13 is hinged adjacent the lower end of the screen to be swung downwardly against the supporting bracket 22 to form a chute for delivering the unburned coal to a suitable receptacle. The door is preferably kept closed during agitation of the screen so that the ash is completely sifted out before the coal is delivered to the receptacle. To look the door tightly closed a suitable spring latch 23 or other lock may be provided. A handle 24 is provided for the door by means of which it can be readily opened and closed.

A cover 25 is provided for the hopper and when opened rests against the bracket 26. A handle 27 is preferably provided for the cover.

The sifted out ash particles fall into the lower part 10 of the housing structure. As shown, a bottom 28 is provided for this section from which the ashes can be shoveled or dumped through an outlet 29 for which a door 30 is preferably provided, this door being kept closed during the sifting operation. If desired, the door and bottom 28 could be omitted and the lower end of the ash compartment left open and the base 31 formed to fit over a barrel, box or other container for receiving the ashes. A handle 32 is provided for the door 30 and also a suitable spring latch or other lock for holding it in closed position. A handle 34 is proture can ,be readily moved about.

The screen structure can be of any suitable construction. As shown, it is in the form of a sheet metal plate 35 havin the "perforations 36 and with its longitu inal sides turned at right angles to form reinforcing flanges 37. It is evident that other screen structures could be used, as for eX- ample, structures utllizing woven wire or parallel bars.

The devlce of my lnvention can be 1nex- PGIlSlVelY manufactured and on account of the oscillating screen structure complete and operation shown and described as changes the invention.

I claim as follows:

In an ash sitter, the combination of a housing, an inclined screen within said housing dividing it into a downwardly inclinedrun-way section and a lower ash receiving section, said screen being pivoted to the sides of said housing to be oscillated to agitate the material to be screened, closure flanges projecting from said housing to engage the screen at its opposite ends respectively, and a bar extending from one end of said screen upwardly to the exterior of the housing whereby the screen may be readily oscillated.

In witness whereof I hereunto set my name this 26th day of February, A. D. 1917.

ABE ARENSON.
