Abstract
Abstract This ash receiving device is designed to prevent ash dust from entering a room when ashes from a fireplace or wood stove are dumped into the device. Primarily, the device consists of a container with a removable ash receiving receptacle on its interior. It also includes a foot pedal operated vacuum producing mechanism in its base, which by an attached hose, will cause outside air to be drawn through openings through an internal chute in which the ashes are dumped to fall in the receptacle. This incoming air being drawn in by suction, pulls the ash dust produced when dumping, into a removable filter included in the chute.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
99 words
An ash container comprising: a base, a container secured to said base, a vacuum producing mechanism secured in said base, a chute secured in said container for receiving ashes removed from a woodstove or fireplace, a hose communicating said vacuum producing mechanism with the interior of said chute through a filter secured in said chute so that a vacuum is created in said chute and said filter retains ash dust and prevents said ash dust from traveling through the air on the outside of said container, and an ash receptacle received in said container and disposed below said chute.
Claim 2
Dependent Claim
99 words
An ash container comprising: a base, a container secured to said base, a vacuum producing mechanism secured in said base, a chute secured in said container for receiving ashes removed from a woodstove or fireplace, a hose communicating said vacuum producing mechanism with the interior of said chute through a filter secured in said chute so that a vacuum is created in said chute and said filter retains ash dust and prevents said ash dust from traveling through the air on the outside of said container, and an ash receptacle received in said container and disposed below said chute.
Claim 3
Dependent Claim
159 words
The combination as set forth in claim 1, wherein said base comprises a diaphragm housing which is fixedly secured at its rim edge to a top surface of a bottom plate, and said vacuum producing mechanism includes a diaphragm which is fixedly secured at its outer peripheral edge to the inner peripheral surface of a side wall of said diaphragm housing and an inner wall secured in said diaphragm housing, and said inner wall is fixedly secured at its top, bottom and side peripheral edges to a top wall of said diaphragm housing, said bottom plate and the inner periphery of said side wall of said diaphragm housing, respectively, and said top wall of said diaphragm housing is integrally attached to said side wall of said diaphragm housing, and said diaphragm housing includes a plurality of spaced cut-out openings through said rim edge for the passage of air from beneath said diaphragm when said vacuum producing mechanism is operated.
Claim 4
Dependent Claim
152 words
The combination as set forth in claim 2, wherein said vacuum producing mechanism further includes a cable which is fixedly secured at one end to a center bottom portion of said diaphragm and is fixedly secured at its opposite end to one end of a foot pedal which is pivotally secured at its bottom surface to a hinge fixedly secured to said top surface of said bottom plate which projects outwardly beyond said diaphragm housing, and a plurality of spatially arranged coil springs are disposed in said diaphragm housing with each spring being secured at opposite ends to a top side of said diaphragm and to a bottom side of said top wall such that said foot pedal when pressed downward will pull said diaphragm downward by means of said cable and produce a vacuum and said diaphragm when moving downard pulls against the spring tension of said plurality of coil springs.
Claim 5
Dependent Claim
83 words
The combination as set forth in claim 3, wherein said cable is fed around the outer peripheries of a plurality of spatially arranged rods which are fixedly secured at their ends to said inner periphery of said diaphragm housing, and said rods provide bearing and support means for said cable, and said cable extends through an opening provided through said inner wall in said diaphragm housing and an opening provided through said side wall of said diaphragm housing outwardly to said foot pedal.
Claim 6
Dependent Claim
153 words
The combination as set forth in claim 4, wherein a first one-way check valve is fixedly secured over an opening provided through said top wall of said diaphragm housing, said hose is coupled to said first check valve at one end and is coupled at its opposite end to a coupling fixedly secured to a cover over an opening there in, said cover is secured to an upper open end of said container, said opening in said cover aligns with a pipe which is fixedly secured at one end to the inner surface of said cover over said opening and is similarly secured at its opposite end to a rear wall of said chute over an opening therein, and the filter is secured over the opening in said rear wall so that when said cable pulls said diaphragm downward, a vacuum is produced above said diaphragm and air is pulled through said filter.
Claim 7
Dependent Claim
80 words
The combination as set forth in claim 5, wherein said cover includes a door disposed over a second opening in said cover, said door being hinged to said cover, said second opening being disposed over an open end of said chute and said filter is removably secured to said rear wall on the interior of said chute by suitable screw fasteners and catches said ash dust from said ashes which are dumped into said chute when said door is opened.
Claim 8
Dependent Claim
34 words
The combination as set forth in claim 6, wherein said chute is in alignment with the second opening in said cover and said pipe is the support means for said chute within said container.
Claim 9
Dependent Claim
77 words
The combination as set forth in claim 7, wherein said chute includes a total of four walls, one of which is said rear wall, another is a front wall and a pair of side walls are fixedly secured to said rear wall and said front wall, and a plurality of spaced openings are provided through said side walls to vent air in said ash receptacle when said vacuum is created to pull the air through said filter.
Claim 10
Dependent Claim
70 words
The combination as set forth in claim 8, wherein a second one-way check valve is fixedly secured over a second opening through said top wall of said diaphragm housing so that after the vacuum ceases and said diaphragm returns to its normal upward position by the tension of said coil springs, said first check valve closes and simultaneously said second check valve opens and releases air trapped above said diaphragm.
