JOHN A. KEssEL, or U F LO, NEW. YORK.

To all whom it mag concern. I

Be it known that I, JOHNA. KESSEL, a citizen of the United States,cresiding at Buffalo, in the county of Erie and State .of New York, have invented new" and useful Improvements in Ash-Sifters, of which the following is a specification.

This invention relates toanash sifter which permits of sifting ashes without permitting dust to escape to the surrounding atmosphere as is. commonly. the case in ash sifters as heretofore constructed. It is the' object of this invention to produce a sifter of this character which'is simple and inexpensive in construction, which can be'easily operated, and which permits of conveniently separating the dust and clinkers from'the good coal without removing the sieve from the sifting chamber and thereby render the sifting operation cleanly, and agreeable.

In the accompanying drawings:

Figure 1 is a perspective view showing one form of ash sifter embodyingmy invention. Fig. 2 is a vertical section ofv the same taken on line 2-2, Fig. 3. Fig.3 is a horizontal section taken on line 33, Fig. 2. Fig. 4 is a fragmentary vertical section taken on line4-4, 3. Figs. 5'and .6

are perspective views of the two sections of the sieve forming part of my invention. Fig. '7 is a similar view of a scoop for use in placing the ashesto be sifted intothe sieve within the sifting chamber. Fig. 8 is a vertical section ,of an ash siftershowing my improvements in a slightly different form from that shown in Figs. 1 and 2.

Similar characters of referenceindicate corresponding parts throughout the several views. In the form of my invention shown in Figs. 1 and 2', the sifting chamber is formed within an inclosing casing which preferably comprises an upright cylindrical wall 1 havingan open top, and a cover 2 adapted to close this top, both of these members being preferably constructed of sheetmetal in any suitable manner. The outer side of the sifting chamber may be provided with handles 1 for carrying the same and the ,cover may be providedwithahandle 2 for lifting W'ithinv the lower part of this Slftlllg.

or rim 4 whichrests with itsunderside on the supporting lugs 3 and a partition 5 extending across the space within the sieve frame on one side of its center or axis of rotation so as to form two compartments in this frame one of which is comparatively large and the other comparatively small. A large main screen section 6 is permanently secured to the lower end of the large com .partment of the sieve frame and a small auxiliary screen section 7 is removably arranged in the small compartment, of the sieve frame and adapted to rest on lugs or shoulders 8 formed on thesieve frame within the small compartment thereof. If 'de sired the'small; sieve "section may be pro- 1 vided with a rim 9 for stiffening the same and also with a handle 10 secured centrally to its uppersidefor the purpose of removing it from the sieve frame when required.-

The sieve as a whole may be introduced into the sifting chamber from its top and also removed therefrom by means of handles 11, llxsecured to the peripheral wall thereof on its-diametrically opposite sides, as shown in Figs. 2. 3 and 6- The-horizontally oscillating or shaking movement is impartedto the sieve by means of ahandle 12'projecting through a:horizontal slot 13 in the side wall of the sifting chamber and connectedat its inner end to :the main frame or wall of the sieve. This handle is made detachable from the sieve frame in order to 'permit'the latter to'be removed from the sifting chamber for dumping 'the good coal out of the sieve. This detachable connection may be constructed in various :ways, for instance, by providing the inner end of the shaker handle with an externally screw threaded shank 14 engaging with a screw threaded opening or socket 15 in the wall of the sieve frame, as shown in-Figs. 3, 4 and 6. Upon shaking the sieve the dustpasses downwardly from the underside thereof while the large particles, such as the good coal and clinkers, are retained within the main and auxiliary sieve sections. In order to permit of conveniently removing the clinkers from the good duces a flattening on one side of the main sieve section which provides the necessary passage through which the chnkers may be removed from the good coal and thrown into the dust pile below without necessitating removing the sieve from the sifting chamber. 1

Means are provided whereby the ashes to be sifted may be introduced into the sitting chamber and deposited within the sieve without producing any appreciable dust outside of the sitting apparatus. For this purpose the sitting chamber is provided on one side of its wall with a laterally pro jecting hood 16 which is preferably of rectangular form and provided at its outer end with an ash inlet opening 17. This opening is surrounded by a flange 18 which inclines from its upper end inwardly toward its lower end so as to form a seat 19 on the inner side of this flange which is adapted to be engaged by a vertically swinging gate, valve or shutter 20. This shutter is pivoted at its upper end on the inner side of the hood, as shown at 21 and is held normally by gravity in its closed position against the seat around the inlet of the hood.

The ashes are preferably removed from the ash pit of a furnace, stove or other place and passed through the inlet of the sitting chamber and deposited upon the sieve there in by means of a scoop 22 which is of cylindrical form and provided with'an inclined front end and the handle 23 at its rear end. As the front end of this scoop enters the inlet of the sifting chamber it engages with the shutter and pushes the same inwardly into an open position, as indicated by dotted lines in Fig. 2, and upon withdrawing this scoop after depositing the ashes on the sieve the weight of the shutter automatically returns the same to its closed position, as incheated by full lines in Fig. 2, thereby effectively preventing the escape of any dust from the interior of the sifting chamber to the surrounding atmosphere.

During the operation ofsiftin the ashes there is no tendency of any of the dust to escape through the slot 13 in the side wall of the sifting chamber because there is no air current through this opening and for the further reason that this slot is practically covered by the annular frame of the sieve, as shown in Figs. 1, 3 and 4.

As the dust drops from the underside of the sieve the same may be taken care of in any suitable mannerand received either in a reit'use receptacle or can 24 which is separate from. the sitting apparatus proper, as

I shown inl igs. 1 and 2, or in a receptacle 25 which is formed in one piece with the wall 8. \Vhen the sitting chamber is made separate from the refuse receptacle the lower endiof the wall of the sitting chamber is provided with an annular base flange 27 whereby the same may rest either uponthe ground or floor when the sitting apparatus is not in use, or the samemay rest upon the upper edge of and form a tight joint with an Lash receptacle which is of the proper size 2G of the sifting chamber, as shown in Fig.

to fit the lower edge of the base flange, as

shown in Fig. 2. V

Inorder', however, to permit this sifting apparatus to be used in connection with ash cans or refuse receptacles which are of smaller diameter the interior of the sitting chamber is provided below the sieve with a downwardlytapering conical guide 28 which latter may be supported with its underside on the upper edge of an ash can or receptacle of smaller diameter, such' a can 29 being shown by dotted lines in Fig. 2. The baseflange of the sifter' preferably extends downwardly below the lower end of theguide 28 so that the latter will not be injured when the base flange rests 'on the floor. By this'construction of ash sitter the same may be used in connection with any available can or receptacle for receiving the dust and clinkers and the same may be removed therefrom before the ash man carts away the can, thereby avoiding injury to the ash sitter, i

lVhen the ash receptacle is made in one piece with the sifting chamber, as shown in Fig. 8, the ashes may be removed therefrom into another receptacle which is to be handled by the ash man in order to avoid damage to the sitting apparatus.

Owing to the dust resulting from this sifting operation being positively confined A within the sifting chamber in this apparatus it permits this operation to be performed in the basement or other available place of a building without causing any objectionable spreading of dust into the surrounding space, thereby rendering the operation of sifting the ashes more sanitary, pleasant and convenient. l

Moreover, this ash sitter has no delicate parts which are liable to get out of order andowing to the simplicity of its construction the same can be produced at comparatively low cost.

I claim as my invention:

1. An ash sifter comprising a cylindrical siftingchamber having its axis arranged vertically and provided with internal supports, and a circular sieve adapted to rest sifting chamber havingits axis arranged vertically and provided Withinternalsupports, and a circular sieve adapted to rest on said supports and to'oscillate horizontally thereon and having a large main section and a small auxiliary section; the division between said sections being on one side of the center of the'axis of the sieve.

3. An ash sifter comprising a sifting.

chamber containing an internal support, and a sieve engaging said support and'having a frame, a main screen section permanently connected with said frame, andan auxiliary screen section detachably mounted on said frame.

4. An ash sifter comprising'a sifting chamber containing an internal support, and asleve engaging sald support and having a frame, 'a comparatively large screen section permanently connected With said frame, and
