Abstract
Abstract Apparatus for separating particulate solid material from a stream of gas, such as air, entraining such material includes a blower, a solids collection receptacle, ducting connected to the blower and to the receptacle and communicating with a source of gas with entrained particulate solid material, the blower, receptacle and ducting providing a substantially closed system in which gas is recirculated, the solid material being separated from the circulating gas and deposited in the collection receptacle. A portion of the circulating gas, usually not exceeding 30 percent by volume, is bled from the circulatory system and discharged to maintain the average pressure in the circulating system at a desired low value so as to prevent leakage blow-out of gas and entrained dust or fine solids. Means for bleeding gas off from the system is situated within structure housing the blower and a separation chamber. The solids collecting receptacle is mounted so as to be bodily movable away from the blower and ducting housing structure and so as to respond to such bodily movement by tipping to dump accumulated solids. The gas cleaning apparatus is disclosed in connection with mobile surface sweeping equipment including a pick-up head having means for regulating the flow of air from a pressure chamber against the surface being cleaned and into a suction chamber in the pick-up head.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
268 words
In apparatus for separating gas from particulate solid material entrained therein, a support; a housing mounted on said support and having one face thereof extending generally vertically; a blower in said housing; first duct means in said housing extending through said one housing face and to the blower intake; second duct means in said housing extending through said one housing face and to a source of gas with particulate solid material entrained therein; means comprising a solids collection receptacle for separating gas from particulate solid material entrained therein, said solids collection receptacle having an open face; means mounting said receptacle on said support normally with said open face thereof covering said one face of said housing with both of said duct means communicating through said one housing face with the interior of said receptacle, whereby gas in said receptacle is withdrawn therefrom through said first duct means and through said blower intake with resultant drawing of gas and entrained solid material through said second duct means into said receptacle to pass therethrough with separation of solids from gas and passage of gas out through said first duct means into said blower intake; and operating means for moving said receptacle away from said one face of said housing, said receptacle mounting means including position control means responsive to movement of said recepTacle away from said one face of said housing for bodily elevating said receptacle relatively to said housing and to said support to a position spaced above said support, and for also tipping said receptacle to discharge solid material from the elevated receptacle through said receptacle open face.
Claim 2
Dependent Claim
268 words
In apparatus for separating gas from particulate solid material entrained therein, a support; a housing mounted on said support and having one face thereof extending generally vertically; a blower in said housing; first duct means in said housing extending through said one housing face and to the blower intake; second duct means in said housing extending through said one housing face and to a source of gas with particulate solid material entrained therein; means comprising a solids collection receptacle for separating gas from particulate solid material entrained therein, said solids collection receptacle having an open face; means mounting said receptacle on said support normally with said open face thereof covering said one face of said housing with both of said duct means communicating through said one housing face with the interior of said receptacle, whereby gas in said receptacle is withdrawn therefrom through said first duct means and through said blower intake with resultant drawing of gas and entrained solid material through said second duct means into said receptacle to pass therethrough with separation of solids from gas and passage of gas out through said first duct means into said blower intake; and operating means for moving said receptacle away from said one face of said housing, said receptacle mounting means including position control means responsive to movement of said recepTacle away from said one face of said housing for bodily elevating said receptacle relatively to said housing and to said support to a position spaced above said support, and for also tipping said receptacle to discharge solid material from the elevated receptacle through said receptacle open face.
Claim 3
Dependent Claim
135 words
Apparatus according to claim 1 in which said means mounting said receptacle on said support comprises a relatively long link pivoted at one end to said support at a point relatively remote from said one face of said housing and at a relatively low level and pivoted at its other end to said receptacle at a point relatively close to said receptacle open face and at a relatively high level; and a relatively short link extending above said relatively long link when said receptacle is positioned, as normally, with its open face covering said one face of said housing, said relatively short link being pivoted at one end to said support remote from said one face of said housing and being pivoted at its other end to said receptacle close to said open face thereof.
Claim 4
Dependent Claim
30 words
Apparatus according to claim 1 in which said receptacle mounting and position control means comprises two links both connected at opposite ends to said support and to said receptacle respectively.
Claim 5
Dependent Claim
21 words
Apparatus according to claim 3 in which said two links, said support, and said receptacle together constitute a four bar linkage.
Claim 6
Dependent Claim
35 words
Apparatus according to claim 3 in which said operating means comprises a power operated extensible assembly pivoted at its opposite ends respectively to said support and to an intermediate point of one of said links.
Claim 7
Dependent Claim
298 words
In apparatus for separating gas from particulate solid material entrained therein, a support; a housing mounted on said support and having one face thereof extending generally vertically; a blower in said housing; first duct means in said housing extending through said one housing face and to the blower intake; second duct means in said housing extending through said one housing face and to a source of gas with particulate solid material entrained therein; means comprising a solids collection receptacle for separating gas from particulate solid material entrained therein, said solids collection receptacle having an open face; means mounting said receptacle on said support for bodily movement from a normal position to a discharging position, said receptacle open face facing towards and covering said one face of said housing with both of said duct means communicating through said one housing face with the interior of said receptacle when said receptacle is in its normal position, whereby gas in said receptacle is withdrawn therefrom through said first duct means and through said blower intake with resultant drawing of gas and entrained solid material through said second duct means into said receptacle to pass therethrough with separation of solids from gas and passage of gas out through said first duct means into said blower intake, said receptacle open face being displaced from said one face of said housing and facing away from said one face of said housing when said receptacle is in its discharging position; and operating means for moving said receptacle from said normal position thereof to said discharging position thereof, said receptacle mounting means including position control means responsive to movement of said receptacle from said normal position thereof to said discharging position thereof for tipping said receptacle to discharge solid material therein through said receptacle open face.
