Begitknownthat I, HERMAN. C. STERN., a citizen` of United Statearesiding. at Wauke-- sha, in the county of Waukesha, Stateof Wisconsin, have invented certain; new and useful Improvements in. AshfSifters g, andv I do hereby declare the following; to, be a full, clear, and exact description of 4the invention, such asi will enabley othersskilled` inthe art towhich, it appertains to make and use the same.y n

Henetofore, in theclass. of ash sifters, various actuatingdevices.- have been proyided, but irrespective thereof, l theconstruction of thedevicel was 4such that whether the f sif-ter was? of the rotary or. reciprocating typeor had other formofagitating means,.theiss1.lr ance of dust could nQtbepreVentedand-the depositing of ashestoj` beI sifted, aswellas' thel discharge .off `the cinders .and the Y. emptyingof the siftings on screenings could only be accomplishedwith difficulty.

It is thereforean` object ofmy invention to provide an ashsifter sofconstnucted as to possess improuements not. only in facilitating the operations above set. fonthfbut.. also to improve andsimplify'the construction thereof, by providing a. support. inv7 which. is hung in a. novel manner, a.container,v adaptedthrough. theI medium` of novelmeans, to be agitated ory have impar-ted thereto,` a, reciprocating oscillatory motion, for; separating the dust and ner particlesl .fnonnthe coalsfand larger particles or cinders, as well as to. facilitate the depositing ofthe ashes fon the; sifting.. operating and the. ysifting .thereof withgthe least possible escape of dust, .both.diining the agitation ofthe, sifte-r and, in :emptying or discharging` the-cinders andthe dust.

The invention.` further comprehendsl an improved ash 'sigfter-embodying. a container s.lispeilsild` by' a Series, 0f harleer'sehd adept.'- ed to be .agitated with anv oscillatory reciprocating.. motion by, means; of 4aghandle or lever. supported byv the carnyingframe, the container. having).hingedl thereto,j ascreen in the formvof a tray provided with a. sliding @over permitting the depositing@ theahes to befsiftedbut .servin to `-prevemt .the escape of dust during anda ter ythe. sifting operaten; aswell as. a remerablgepaefor: receiving the dust or screenings, while a. fastener eprptided to serre the @cable @when 0f holdingthe hinged tray ofthe ,screentoward the containerandal'so to hold the'panfin 2L. closed position. j i.

imparted thereto, an oscillatory reciprocating motion `for the purpose ofagitating the ashes to separate the dust and finer particles from the coals andlarger .particles of the cinders, as it is thought Will be comprehended. For this purpose there is pivoted to be imparted to the container for agitaftng.

the same as heretofore set forth.

The container is designed to carry the screening mechanlsm and for this purpose,

, the upper longitudinal edges of the side portions of the container arey rabbeted at their inner sides as shown at 18 to provide guide- Ways for the reception of a screen tray T forming part of the ash sifter. This tray is in the form of an open rectangular tray or frame, the side portions 19 of which have their lower edges rabbeted at the outside to interfit the guideWa-ys produced by the rabbeted upper edges of the base portion of the container, vso as to produce a Vdust-proof joint. This joint also lfacilitates the replacement of the screen trayupon the con tainer, when said tray is shiftedV from a position to discharge the ycontents thereof, to a position upon the container, for the sifting operation. n

The tray ,is provided with a'Wire mesh bottom 2O serving the function of a .screen or sieve andl with an inclined end Wall 21 arranged for disposition above the inclined end Wall 15 of the container, the abutting edges of these Walls being hinged together as shown at 22, so as to permit the tray to be tilted from a position of rest supported horizontallyI upon the container at the upper edges thereof inthe manner specified, to a rearwardly inclined position for discharging the cinders. v The container is designed to Vreceive a pan 23 which is slidably received Within the open end of the container, the innerV end Wall 24E ofthe pan being inclined in conformity With the adjacent end Wall of the container when the panis in position, While the outer end Wall 25 extends outwardly to abut the edges of the side Walls and bottom of the container as an additional means of producing an effective seal against the escape of dust and ashes, so desirable in a device of this character. The tray T is provided With an end Wall 26 disposed abovevthe end Wall 25 and the side Walls 19 areprovidedwith grooves 27 inthe inner faces thereof to receive a sliding cover 28 which projects over the end Wall 26 to form an additional seal against the Vescape of dust. Locking means is also provided to serve the double function of holdingthe hingedrtray toward the container and in sealing engagement therewith during the sifting operation, as Well as to secure the pan in a receiving position as illustratedvmay consist of a hook 29 designed to engage a stud 30 projecting from thefvvall 2511of'the'pan. In this manner when the sifting operation has been completed, the tray can be tilted to discharge the coals andvvcinders retained therein and the lpan'can be-removed to discharge or empty the dust and finer particles which have sifted through the screen. It is' important in accomplishing the objects sought, that the sliding ycover 28 may be drawn as far as desired so as to uncover only the bottom portion of the tray during the discharging thereof, so vthat the dust 'will be prevented from arising and scattering over the operator, While the-relation ofthe parts is such aste prevent the escape of ythe` dust particles during the sifting operation, but

in permitting same to settle before emptying the pan of its contents. Thus the objects mentioned have been accomplished in an effective manner and with a device possessing a considerable number fof v*points of advantage in simplicity of construction and operation, asv Well asv from a5 commercial point of View as relates to its possibilities of manufactureand production for sale.

Having thus described my invention, what I claim and desire to secure by Letters Patent of the United States is:-
