AUTOMATIC ASH-SIFTER.

Application f nea retreat-y 2e, isos. smal Nxuso.
of Manhattan, ,in the county and State of vided with a removable door 3*.
New York, have invented a new and Imroved Automatic Ash-Sifter, of which the ollowing is a full, clear, and exact descrip tion.
My invention relates to sifters for loose materials, such as ashes, my more particular object being :to ,prevent the formatlon of excessive dust during the sifting process, and also to effectively separate the coarser materials from the fine dust.
y More particularly stated, my invention is an ash sifter of simple and convenient form, wherein the nuisance due to flying ash dust is abated as far as practicable, and in which a large pro ortion of coal and cinders remaimng 1n t e ash is extracted by the automatic action of the device.
Reference is to be had to the accompanying drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts in both the Y figures.
Figure 1 is a perspective showing my improved ash sifter mounted upon the top of an ash-can and ready for action, this view showing the hopper into which the ashes are poured at the start, and also showing the swinging door at the bottom, whereby the coal cindcrs, clinkers and other larger portions of material are ejected automatically; and Fig. 2 is anA enlarged central section through the ash-sifter showing the chutes for fine ashes and coarser materials and the Vvarious doors,screens and batlles.
" An ashcan top is shown 'at 3 and is pro- Resting ulpon the top 3 is a box frame having an inc med portion4 and a short vertical ortion. Mounted within the portion 5 is a lopper 6 provided at its bottom with an opening 7.
isposed below this opening and mounted within the portion 5 is a plate 8, incline obliquely downward to the proximate center of the portion 5. A swinging door 9 is mounted upon the hopper 6, and is normally pressed against the plate 8 by aid of a spring 9. At 10 is a screen. mounted within the inclined portion 4.. is connected with the tower end of the screen 10 and molines slightlyv backward under the screen 10, or to the lf-it, according to Fig. 2.
rigidly A baffle-plate 11.
Another screen 12 is disposed parallel with the screen 1.0, but in a plane slightly lower than that of this screen. The screen 1.2 is supported upon a rod 13 extending directly across the box fratrie and engaging the'baffle plate 11.
Mountedupon a stationar wall 14 `is a baiile late .15 inclined inwardI or to the left accor mg to Fig. 2. A door 16 is mounted upon the wall 14 and is adapted to swing outwardl as will be understood from Fig. 2. This oor is normali held by its own weight against a wall 17 w ich supports the lower end of the screen 12.
At 18 is a baffle plate mounted upon the top 3, thistop being provided with an openin into which the plate 18 pro'ects, as Wil be understood from Fig. 2. he box frame is supported by a brace 19 connected rigidly with 1t.
The operation of my `device is as follows: The' doors 9 and 16 bein normally closed, as abbve described, the as es are oured into the hop er 6. Theass throu the o Vening 7 an fall upon t e inclined p ate 8 w ich directs them to the left. `The door 9is opened by the weight of the materials, and the lattenare thence poured upon the screen 10, striking the same at a very abrupt angle. The fine ashes pass through the screen 10 and are guided obhquely downward through the opening 20 into the ashcan. The coarser materials, such as cinders and unburned coal, roll down the screen-10 and bounce onto the screen 12, shaking the latter. which may rest u on this screen are thus shaken throu h and) ass into the opening 20. Some of the er asllxes passing through the screen 10 follow this screen downwardly to its lower end, and then, passin through, strike the ,plate 11, being thus de ected to the left and prevented from reaching thescreen 12. Any material striking the baffle plate 15 is projected to the left and madeto strike the screen 12 so as to sift the finer 'materials through the latter. Finall any material left. he coarser materials, piece by piece, strike the door 16 and open it, and this door, being closed by its own weight, revente, as far as practicable, the escape o fine ashes and dust into' the outer atmosphere. The door 9 acts to some extent in the same manner, in that it prevents upward travel or reing to contaminate the air. Every chance,
Any fine ashes strikin the plate 18 is ba ed towardy the 11o trogression of any loose or ine materialtendi however, is afforded for the removol of the cocrser materials which/as experience has shown, havo more or loss value as fuel.
Hoving thus Vdcscribcd my invention, l claim as new end desire tio secure by Let'ters Patent:
In on ash sil'tcr, the combination of a. box frame provided with n. vertically disposed i portion and wlth an inclined portlon, Yn. hop- 1 per mounted unon said verticolly disposed portion, a, pleite disposed within said Vertily disposcd portion and extending alpprogii imntcly from thc edge of said vel-tica ly disposed portion, o, swinging door mounted upon said hopper, a spring connected with said i hop er and with said swinging door for no1'- nmly forcing seid swinging door lnto e11- gogcmcnl will sind pleite, o, pair ol screens EDWARD J. DEEGAN.
