G. DONNELLY ASH SIFTER Filed May 8, 1929 Patented Mar. 25, 1930- GEORGE G. DONNELLY, OF'SOMERVILLE, MASSACHUSETTS ASH SIFTER I Application filed May-8,

This invention relates to an ash shifter and has for its object to provide a device constructed in such a manner that it may be sold and shipped in knocked-down form, thereby I be rocked through a vertical plane, the fine particles of ashes sifting through the screen of the sieve and falling uponthe main screen in the body of the device through which they will fall and be deposited in an ash receptacle, while the larger particles that do not pass through the screen of the sieve will eventually be dumped upon the main screen down which they will slide and be discharged into a suitable receptacle. v

The invention consists in an ash sifter as set forth in the following specification and particularly as pointed out in the claims thereof.

Referring to the drawings: Y

Figure 1 represents a central vertical section through an ash Sifter embodyingmy in vention.

Fig. 2 is an enlarged vertical section through the top portion of the housing of the sifter as taken on the line 2-2 of Fig. 1, portions of the housing being broken away to save space in the drawings.

Fig. 3 is an enlarged detail horizontal section illustrating the construction of one of the corners of the housing, said view being taken on the line 33 of Fig. 1.

Fig. 4 is an enlarged horizontal section taken on the line 44 of Fig. 1.

Like numerals refer to like parts throughout the several views of the drawings.

In the drawings, 5 represents a cover for an ash receptacle, said cover being constructed of sheet metal and being circular in form. Mounted upon the top of the cover 5 is a housing 6, the interior of which communicates with the under side of the cover 5 through an opening 7 provided in the cover.

Projecting upwardly from the top portion of the cover 5 at the sides of the opening 7 are flanges 8 and 9, the flanges 8 being lo- 1929. Serial No. 361,434.

cated upon opposite sides of the opening 7, and the flanges 9 also being located upon op posite sides of said opening. The housing 6 embodies therein oppositely disposed side members 10 and 11, both of which are pro- 'vided at their'lower edges with upwardly bent flanges 12 which are adapted to be interlocked with the flanges 8 of the cover 5. At their side edges the sidemembers 10 and 11 are provided with flanges 13, see Fig. 8.

The housing 6 also embodies therein side members 14 and 15, both of which have flanges 16 formed along their side edges and the flanges 16 have sliding interlocking en gagement with the flanges 13 of the side mem 'bers 10 and 11. At their bottom edges the f side members 14 and 15 of the housing 6 rest upon the top of the cover 5 and contact with the outer surface of the flanges'Q, see Fig. 4. Atop member 17 ofthe housing 6 has flanges 18 formed upon opposite edges thereofwhich have sliding interlocking engagement with flanges 19 that are formed at the top of the side members 10 and 11. One edge of the top member 17 hasa downwardly bent flange 20 which contacts with the outer face of the side member 15 and the opposite edge of the top member 17 is located beneath aflange 21 which is formed at the topof the side member 14, see Fig. 2. k v Located within the housing 6 is a main screen 22 which is constructed of open mesh wire fabric, and saidscreen is preferably inclined at an angle of approximately 45 to the top surface of-the cover 5.- A pair of rods 23 extend transversely across the housv ing between the side members 14 and 15 thereof in a position to support the central portion of the screen 22 and prevent the same from e'g n Located above the screen-22 and normally resting upon the upper surface thereof is a sieve 24, and a portion of the frame structure 25 of the sieve is extended and pivotally mounted upon a rod 26'which is located ad'- 9 jacent to the side member 10 of the housing. The side portions 27 and back portion 28 of the sieve 24 are constructed of thin sheet metal, while a screen 29 0f open mesh'wire fabric constitutes the bottom of the sieve.

A front edge 3O 01": the screen 29 is so positioned that when it is desired to dump that portion of the material that cannot pass through the meshes of the screen 29, the sieve 24 may be moved to the dotted line position illustrated in Fig. 1, at which time the material remaining in the sieve will all there from and drop on the inclined screen 22 down which it may slide. Thesieve 2a is rocked by means of a lever 31, one end of which is secured in any suitable manner, to the framework of the sieve at a point adjacent to the top edge of the back portion 28 of said sieve, and said lever 31 extends through an opening provided therefor in the side member 10 of the housing 6 and has a handle portion 32 provided upon its outer portion. The lever 31 is pivotally mounted upon the rod 26.

An opening 33 is provided in the side member 10 of the housing 6 through which the ashes may be inserted in filling the sieve 2i, and said opening is normally closed by a door 34: which is pivotally attached at 35 to the side member 10. An opening 36 is also provided in the side member 11 of the housing 6 through which the reclaimed portion 01" the ashes may pass from the screen 22 down a chute 37 into a suitable receptacle.

The general operation of the device herelnbefore specifically described is as follows 'Assuming that the sieve 24 is resting in its normal position on the screen 22, the door 34 is raised and the ashes are inserted through the opening 33 and deposited upon the sieve 24. The sieve is then rocked through a vertical plane as energetically as may be desired to cause the fine material to pass through the screen 29 from which it will drop upon the screen 22, and through which it will drop through the chute 37.

into the ash receptacle not shown. After the fine material has all passed through the screen 29, the sieve 24 is rocked upwardly a sufficient amount to allow the residue to slide out of said sieve and drop upon the screen 22 down which it will pass and be discharged The device as a whole is so constructed that it may be sold and shipped in a knocked-down condition, thereby reducing the shipping cost and the space required in packing and storing quantities of the devices. The device is easily assembled by sliding the side members one upon another and interlocking the various flanges one with another.

It is evident that after the side members are all secured together and to the cover 5, and the top member 17 has been slid into position upon the side members, that the structure may be strengthened by inserting bolts through the various flanges, thereby clamping the members together.

I claim:

1. An ash sitter comprising, in combination, a cover for an ash receptacle, a housing mounted upon said cover, a screen mounted in an inclined position within said housing, and a sieve pivotally mounted within the housing and normally resting upon the screen.

2. An ash sitter comprising, in combination, a cover for an ash receptacle, a housing mounted upon said cover, a screen mounted in an inclined position within said housing, and

a sieve pivotally mounted to swing through a vertical plane within the housing above the screen.

3. An ash sitter comprising, in combination, a cover for an ash receptacle, a housing mounted upon said cover, a screen mounted in an inclined position within said housing, a sieve pivotally mounted within the housing and normally resting upon the screen, and a lever to rock the sieve.

4. An ash sitter comprising, in combination, a cover for an ash receptacle, a housing mounted upon said cover and embodying therein a plurality of side members slidable one upon another and interlocking with the cover, a top member slidably mounted upon the side members, a screen mounted in an inclined position within said housing, and a sieve pivotally mounted within the housing and normally resting upon the screen.

In testimony whereof I have hereunto set my hand.

GEORGE G. DONNELLY.
