DUST REMOVER.

. 1 Application filed July 31, 1923, Serial No. 654,909.

T 0 all whom it may concern.

Be it known jthat I, WILLIAM A. a citizen of the United States, residing at Clinton, in the county of Clinton'and State of Iowa, have invented certain new and useful Improvements in Dust Removers, of which the following is a specification.

The object of this invention is to provide an inexpensive device which may be connected with any heating furnace and by the use of which the dust arising from ashes when the same are removed from the furnace and deposited in an ash can or other receptacle may be carried ofi througl. the chimney and prevented from. rising through the house or other building or settling upon objects stored in the cellar in -which the furnace is set up. The invention seeks to provide a device for the stated pur pose which will not interfere in any way with the operation or efficiency of the furnace and which may be very quickly and easily adjusted for use when the ashes are to be removed. The invention is illus trated in the accompanying drawing and will be hereinafter fully set forth.

In the drawing:

Figure 1 is an elevation of a furnace having my. dust-removing attachment applied thereto, and

Fig. 2 is an enlarged vertical sectioL through the attachment and the adjacent portion of the furnace.

The furnace 1 may be of any well-known typeand is illustrated as a hot-air furnace having an outer casing 2 connected b flues 3 with the various rooms of the building, and also equipped with a smoke flue 4 establishing draft through the firebox 5 and the chimney. In carrying out my invention, I provide an opening 6 in the wall of the fire-box, and to the outer side of the furnace I secure a sleeve or tube 7 which extends from the fire-box through the casing 2 and has the end edges of its side walls inclined downwardly and outwardly, as shown at 8. To the upper side of this sleeve 7, I hinge a door 9 which will ordinarily be held in closed position by gravity so as to rest upon the inclined edges 8 and positively shut off circulation of air through the tube, as will be readily understood. I also secure to the casing 2 a housing 10 which may have its vertical wall in arcuate form concentric with the casing or may be of angular design as preferred. The 'upper portion of this MATZ,

casing constitutes a hood 11 which 7 fits around; the sides andthe top of the flue or sleeve 7 so as to entirely house the same and the door or closure 9 therefor, the front of the housing below the hood being open, as

shown at 12. In the top of the hood is an opening 13, and pivoted to the closure 9 7 near the lower edge thereof is a rack bar 14 extending through the said opening 13 and constituting a handle by which the door may be manipulated. The teeth or lugs 15 of this rack bar are adapted to engage the top of the hood at one edge of the opening 13, as shown clearly in Fig. 2, so as to support the closure in its opened position.

When the ashes are to be moved, the

usual fuel door 16 of the furnace and the damper therein are closed and the damper in the smoke flue 4; is opened. The ash pit door 17 is, of course, opened so as to permit accessto the ashes and a strong draft will thus be created through the furnace and the flue 4, as will be readily understood.

The ash can or other receptacle 18 is placed upon the housing 10 through the open front side thereof and the closure 9 is opened, as shown in Fig. M 2. As a result of this arrangement, a strong draft through the shower tube 7 will be set up so that, when the ashes are dumped into the can 18, the dust arising therefrom will be drawn through the sleeve 7 into the fire-box of the furnace and thence out through the flue 4 and will be carried out through the chimney instead of flying about the cellar and settling on objects therein and rising through thehouse to the damage of furniture and drapery. My device is exceedingly simple in construction and may be readily applied to any furnace. When it is not to be used, the closure 9 is permitted to drop so as to cut-off circulation through the sleeve 7 and the draft through the furnace is then regus lated in the usual manner. The device takes up very little room in the cellarand does not necessitate any very substantial alteration or reconstruction of the furnace, it

being necessary merely to form openings to at a point removed from the fueldoor, of a 'tube encloslng and extending laterally from said opening, a closure hinged at the upper edge of the outer end of; said tube end adapted to entirely'cover the outer end of the tube, a housing secured to the side of the furnace and including an upper hood completely housing said tube and the closure therefor and having an open bottom below the tube, the lower portlon of said housing extending from the lower edge-of the hood to the floor upon which the furnace rests and having'its front side open to admit a receptacle, and a rack bar pivoted to said closure and extending therefrom through 15 the top of the hood and engageable. with the top of the hood to support the closure in openposition.

In testimony affix signature.

whereof I my WILLIAM A. MA'rZ 1.5.1
