p SPECIFICATION; TO ALL WHOM IT MAY CONCERN: p Be it known that I, PAUL CEREDO, of Prussia., now temporarily `residingin] Montrealrin the Province of Canada East, haveinvented a new and improved lScreen or Sifting Device; andIdohereby dcclarca` that the" p p following is a full, clear, and exact description thereof, which will enable tlioseslrilledli'n theiarttouniakeand 1i e Y use the same, 4reference being had to the accompanying drawings,lforming partio'f thisfspecication, inhichfi A i Figure 1 is a side sectional view of my invention. i i Figure z2, a horizontal section of the same, taken in the linea: 5:, g. 1.

Similar letters of reference indicate corresponding parts. p A p p A A l i p A, This invention relates ,to a new and improved screen or sifting devicefor separating, ashes from ciuders lo screen-box, providedwitha proper screen, and fitted within a suitable case or bok soasto `work on als `013 A pivots, andioperated through the medium of a cam and spring, the case in which saidlscreen-,box is place be' provided with discharge spouts so arrangedin relation with the screen-box as ,to discharge` `the `two parts," whichi are separated from each other by the' screening process, from different partsof: the `ewand `int parat receptacles prepared to receive them. e 'l i Y l l `3 A represents a case, the upper part, a, of which is of reetangulariand ,the` lower ;par`t",\b i' pyramidal form. This case is supported at a suitable height by means oflegsc, an hin pp a, of the case there `isplaced a rectangular screen-box, B, havinga screen, 0,w i i i This screen-box has a slightly inclinedposition, and it Ais providedQatueaohiside oi" he loweifp the front or depressed 'end of the screen-box, when at its lowest point, restingo `the ruppe of the sides of the lower part, b, of `the case A-see iig. 1. D representsa shaft,` through the upper part, a, of the case, and has a cam, E, upon it of triangular forni, the screen-box, and the cam E acting uponor against a pin in' the front ,partiofpt site and `free end bearing upon the upper part of the depressed end of the screen-boi at ab is a hopper, which is fitted in the top of the case A, and conducts the material` t 'ft B, at its elevated 4end. A A, the lower end'of the part b of thei case A, there is "'ope is attached, exibleor rigid, and a spout J is attached to the end of thepart a of `the x f, which is in line with an opening, g, in the depressed end of the screen-boxBsV f i The operation is as follows: The substance to be screenedI or sifted isz poured into` theA hoppergj,

conducts itinto the screen-box, B, at its elevated end, and, motion being communi d to` the shaft; i i i convenient power, the cam, E, will raise the depressed end of the screenboir,"]`3,j1n sequence ofgtheangles ofl the `cam striking against thepin F, the screen-box being forced down, as ,eachpromiuence ofthe cani passes the pin, bythe spring G. By this `means avibratory motion is givenkthe screenbo i dithe `fine part' i the substance being screened pass through the screen C and down into the llower i i i discharged through the spout I into any convenient receptacle prepared to particles which cannotpass through the screen are discharged fromthe depressed end` opening, g, in the depressed end of the screen-box, and through an opening,f, in theca conducts them into areceptacle prepared to receive them. In sifting heavy llsiibstances1 dispensed with, as the screen-box B will in that case fall suiciently quick under `tliefweght of `itsfcoirt` in sifting `light substances the spring would be desirable-in order to `insure a `vly;` motion of the scree Having thus described lnyvinvention, I claim as new, and desire to secureiby ,Lett sPaten The arrangement of the screen-box B, cam E, springG, spouts IJ, `cmxatruct nd `oper` manner and for the purpose herein specified.`
