ASH-SIFTER.

SPEGIFIGATI ON formingpart of Letters PatentNo. 2'71,751, dated February 6, 1883.

Application filed September 28,1882. (No modeLl To all whom it may concern Be it known that I, ROBERT S. VAN ZANDT, of the city of Brooklyn, in the countyof Kings and State of New York, have invented certain new and useful Improvements in Ash-Sifters, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, and to the letters of refence marked thereon.

large to pass through the meshes of the sieve- -.to. travel to the lower end of the sieve, falling into a receptacle prepared for the purpose, said receptacle being located in such a position as to permit the placing of a coal bucket thereunder, into which the sifted and cleaned cinders may be dumped at will, the whole operation of sifting the ashes being accomplished by the force ofgravitation withoutother labor than emptying the ashes as it comes from the stove into the elevated end of the device.

' In the drawings, Figure l is a perspective view of my improved ash-sifter, and Fig.2 is a vertical longitudinal sectional view thereof, showing the location and arrangement of the interior parts.

Like letters of reference, wherever they occur, indicate corresponding parts in both figures.

A shows the side walls of the device. B and B are the ends thereof, constructed of wood or other suitable material, the end B being divided into two angles, as shown, for the purpose of conveying any ashes that 7 may fall thereon to the receptacle 0r barrel 0, upon which the sit'ter is mounted.

D is the top'of the device,provided with covers D and D one at the upper extremity and the other at the lower extremity thereof.

E is a sieve or screen securely attached to the sides of the device, and extending from the end B to within a short distance of end B, as plainly shown. i

F is a cover upon which the device is placed,

adapted and arranged to fit upon a barrel or other receptacle, as in Fig. 1.

At the lower end of sieveE the device projects over cover F, and a receptacle or chute, G, is there located, provided at its lower extremity with a sliding trap or door, H, through whichthe sifted coal may be allowed to escape. When constructed and arranged in accordance with the foregoing description the operation of my improved siftcr is as follows: Cover D is thrown back and the ashes and ci'nders are emptied therein and the cover immediately closed, preventing the escape of dust. The force of gravitation will cause all pieces of unconsumed or partially consumed coal to pass to the lower end of the sieve, while all dustand refuse will fall therethrough into the barrel beneath. In passing down the incline, where the coal is partially consumed, the ashes clinging thereto will be effectually removed, leaving the cinders in a proper shape for again placing in the stove, and all this without the exercise of any labor whatever upon the part of the oper ator, with the exception'of emptying the unsifted ashes into the device. After the coal has all passedto the lower end of the device, into receptacle or chute Gr, cover D may be raised,

and any slate, slag, &c., may be picked from the contents of G, after which trap H may be drawn out, permitting the material to fall into a coal bucket or hod placed beneath chute G.

It willthus be seen that my improved ashsifter admirably answers the uses and purposes for which it is intended.

Having now fully described myinvention, whatI claim as new therein, and desire to secure by Letters Patent, is

An ash sitter consisting of an oblong bottomless case or box, an inclined sieve affixed to the walls thereof and terminating at an opening in the bottom of the case or box, a receptacle provided with a removable bottom or slide, and a frame or cover adapted to be mounted upon a suitable receptacle, substantially as shown and described.
