Description

i To all whom it may concerm cnrrangf r-A rons memori I f 4 WILLIAM. J araatqor ot'fis'taeoattl stalemate, tenant-L antennae.

Be it known that I, WILLIA J. Corr, a subjectof the King of; Great Britain, residing at Kerrobert, in the Province of Saskatchewan and Dominion of Canada,

have: invented new and useful Improvements in Ash-Sifters, of Whigh the following is a, specification' I a M This invention relates to an ash ejector or device for disposing of the ashes produced by a furnace in a basement .ofa: building, the primary object beingvto provide a de: vice efthis character which} includes a receptacleinto which'the ashes may be poured without causing a 'greatam'ount of dust to rise therefrom, together with/readily operable means for sifting the ashes and conveys.

ing the fine portionsof the same out of the basement to a receptacle disposed upon the exterior of the building.

}-A' further object of. the invention is to:

provide afdevice of this nature, which is through.

simply constructed andcompact so as'rtobe cheap in-the cost of manufacture andinstal= 'lation, and adapted to "occupy a minimum amount of space;

The invention consists in the features-of. construction, comb nation, and arrangement of parts, hereinafterffullydescribed and.

claimed, reference beinghad to. the accompanying-drawings, in which: '1-

' Figure 1 is .;-a vertical longitudinal sectional view; Fig. 2 is a side'elevation of a modified form of the device; Fi g. 3'is a front elevationof the same; and, 4: isa longitudinal vertical sectional view taken there In the drawings, the numeral 1 designates the receptacle or ash'box which is mounted upon the legs 2. The bottom wall of the receptacle includes the. side portions 1 which converge inwardly toward an upwardly and inwardly inclinedconveyer'tube 5. A spiral conveyer 10 is positioned within the tube 5 with the ends of its shaft 11 journaled in the upper and lower end walls 12 and13 of the tube, respectively. A band wheel 14 is secured to the protruding lower end of the shaft 11 and is connected with a second hand wheel 15, which is secured to a horizontal shaft 16 rotatably mounted in the front wall 17 of the receptacle 1 adjacent to its upper edge, by means of a band '18.

ven ifon i he dra ng 1- Th op wall of .he conveyer tubei'5. is cut away at its lower. end as at 2 1 sofas-to afford a mouth for thereception ofashes falling into the receptacle 1. This receptacle is pro! vided in eachside wall 25; thereof; and ad- JaQent to its ,upperedge withan opening 26 which a hinged closure 2.7 is suspended.

Each closure or door 27 is adapted to be swung inwardly when'it is desired tofpour I ashes through the'corresponding side'open-I ingofthe receptacle into the-interior thereof, and serves to prevent the dust-rising 1 within the receptacle from gainingexit through the-said openinggit being under: stood that the top wall 28 of the receptacle 'is' completely closed. A foraminous sifter screen 29 is disposed horizontally within the receptacle 1 at a suitable distance below the openings 26. By the use of this screen, large "cirdcrs and lumps of unburned coal will be collected and may be withdrawn for further.

use as fuel. I

" In using the device,v just. described, the

' ashes are poured through the sideopenings 26 in the receptacle 1 so that the finely di- 'vided portions thereof will pass through the v sifter screen and through the mouthQL of the conveyer' tube into contact with the spiral conveyer "10. Then the handle 28. is,

' grasped and the crank is operated so as to of the conveyer in the proper cause rotation direction, whereupon the ashes will be forced upwardly and outwardly through thetube 5.

In the remaining figures of drawing, a V 110 modified form of the device is shown, wherein a shaker screen 29 is pivoted at its rear edge as at 30 to the front edge of a shelf 31 provided within the receptacle of the device. Thisscreen is inclined upwardly and forwardly from its pivoted edge and has an outwardly projecting arm formed medially on its front edge for movement through a vertical slot 33 provided in the a horizontally disposed rotatable shaft 38 journaled in the front wall of the receptacle beneath the crank shaft previously described. This gear wheel 37 is in mesh with a larger gear wheel 39 attached to thesaid crank shaft. An opening 4-0 having a suitable closure 4&1 is provided in one of the side walls of the receptacle directly above the shelf 8l-for a purpose to be described fullyhereinafter. In using this modified form of the device, the ashes are in troducedin the usual manner through the side openings inthe receptacle. Then, the crank handle is operated so as to cause the conveyer to be set into operation. At the same time, the inclined shakerscreen will be vibrated rapidly by the mechanism just described so as to sift the ashes more thoroughly. The large cinders and lumps of unburned coal that may be deposited upon the screen will gravitate rearwar'dly onto the shelf 31 from which they may be removed by the insertion of a shovel through the opening l0 when the closure or door 41 has been opened. This removal of the large pieces of material should not take place until after the separating operation has been completed and the fine dust within the receptacle has been allowed to settle.

From the foregoing description, taken in connectionwith the accompanying drawings, it should be apparent that I have provided a simply constructed and compact ash ejector which may be cheaply and conveniently installed and which will be highly efiicient in operation. I desire to have it understood, however, that I do not necessarily limit myself to the exact details of construction, with particular reference to the manner in which the crank shaft of the device is connected with the spiral conveyer, or the spe cific means for operating the shaker screen, but that I may resort to minor changes therein, such as fall withinthe scope of the appended claim, if found necessary in practice.

.Having thus described my invention what I claim is: r

A-device of the class described comprising a' receptacle, the said receptacle having its bottom wall inclined downwardly and forwardly and provided at its lower edge with a discharge opening, the side walls of the said receptacle having their lower portions inclined downwardly and inwardly toward the discharge opening, a sifter screen mounted within the receptacle above the inclined portions of the side walls thereof, the said screen being adapted to be, inclined downwardly and rearwardly' and having its rear edge spaced from the rear wall of the receptacle, and a horizontally arranged shelf mounted in the receptacle between the rear wall of the same and the rear edge of the screen.

In testimony whereof I my signature in'presence of two witnesses.
