nace, certain parts of the device being broken away and shown in section better to illustrate the construction;

Fig. 2 is a perspective View of the hood member constituting one part of the illustrated form of my improved device; and

Fig. 3 is a plan view of the ramp or trough member constituting another part thereof.

The particular embodiment of my invention as illustrated in the accompanying drawing, comprises a hood member 10 adapted to be removably placed in operative position with reference to the fire box doorway 12 and the ash pit doorway 13 of '30 a furnace 11 of any improved design, in combination with ramp or trough member 14 adapted to be positioned partly within the ash pit doorway 13 and affording an inclined bottom or ramp 15 over which the ashes may be withdrawn from the furnace by suitable means, as for instance, a hoe l6,

and discharge into an ash can 17 supported at one end by the trough member lfl, the arrangement providing for the creating of i a draft of air from the lower open end of the hood member upwardly through the open fire box doorway in which the major portion of the ash dust will be entrained and thus returned to the fire box.

As shown, the hood member 10 is advantageously formed of sheet metal, or other suitable material, and is shaped so that it gradually decreases in cross sectional area from its lower end, which is open,- and when in operative position, immediately in front of and above the ash pit doorway 13, to ward its upper end which is closed and which encloses the open fire box doorway 12.. The hood member 10 is enclosed at its sides, as at 18; at the front, as at 19; as well'as at the top, as at 20, the free edge of which may be straight or slightly curved, to fit snugly the side of the particular shape or design of furnace with which the attachment is to be used. The hood member 10 0 is supported in operative position with reference to the furnace by means of a suitable support 21, and is advantageously provided with suitable handle means 22 by means of which the hood member may be readily applied to and removed from the furnace.

Cooperating with the lower open end of the hood member 10 is a trough member 14- (see Figs. 1 and 3) having a bottom 15 and upwardly extending side members 23 within the lower side walls of the hood member substantially throughout their length. The side walls 23 of the trough member are in-, clined toward the front end of the bottom 15 so as to present a tapered trough of substantial width at its forward end to extend entirely across the ash pit doorway 13 converging to a more restricted discharge end within the receptacle 17 whereby the ashes may be conveniently discharged into a can or suitable receptacle 17, without liability of spilling av portion of the ashes upon the, floor. Advantageously the forward edges of the side members 23 are bevelled so that when the trough member is supported in inclined position as shown, the front -edges will be flush with the furnace wall, thus preventing the escape of ash dust around the ash pit door.

My invention also contemplates supporting means, such as legs 24, for supporting the trough member in inclined position and also members 25 'on the trough member for supporting the forward end of the ash can 17, and advantageously these supporting members may be formed of single strips of material secured to the underside of the trough as at 26. By this arrangement, the ash can 17 will be in position to receive all the ashes discharged from the trough member.

It will be apparent that the hood member 10 will provide a draft or current of air from the lower open end upwardly through the open fire box doorway 12 so that in drawing the ashes from the furnace over the trough bottom, the dust therefrom will be entrained in the air current and be carried upwardly into the fire box and thence into the chimney.

Advantages of my invention are in its simplicity and the ease with which it may be used. Obviously the side members of the trough members may be fixedly connected to the side walls of the hood member, either frictionally or otherwise, so that the entire device may be moved into and out of operative position as a unit.

I claim:

1. A device for use in removing ashes from furnaces comprising a hood member open at its lower end and adapted to be positioned in front of and covering the firebox doorway of a furnace with its open lower end positioned above the ash-pit doorway thereof, a trough member comprising an inclined surface and supporting means therefor adapted to be positioned relative to the ash-pit doorway of the furnace so that ashes may be drawn from the ash-pit over the inclined surface of said trough member, and supporting means on said trough member adapted to support the open end of an ash receiving receptacle in posii tion to receive ashes drawn from the ash pit by way of said inclined surface.

A device for use in removing ashes from furnaces comprising a trough member adapted to be positioned in operative relation to the ash-pit doorway of a furnace and having a forware edge portion adapted to extend within an ash receiver, supports for said trough member, supports adapted to removably receive and support an ash receiver in position so that the forward edge portion of said trough member will extend into the open end thereof, and a hood member adapted to be positioned in operative relation to the furnace and having its upper end portion formed to discharge into the fire-box doorway thereof, and having its lower end portion formed to constitute a dust receiving hood opening overlying said trough member, substantially as and for the purpose described.

8. A combined ash ramp and receptacle support comprising an inclined bottom wall and side walls forming a trough adapted to be positioned to receive ashes drawn from the ash-pit doorway of a furnace at its inner end for discharge to an ash receptacle at its outer end, and means attached to said trough adjacent said outer end comprising leg members for supporting the trough in THOMAS F.
