Abstract
Abstract An improved mixing device for mixing at least two of a plurality of pressurized liquids, the device consisting of hollow tubular member defined as having a longitudinal axis, one or two open ends and an interior wall member, one of the open ends having at least two cut-out portions generally symmetrically disposed about the axis, a segmental slot member generally radially disposed in the hollow tubular member between each of the cut-out portions for receiving a supporting projection in locking engagement therewith, and an envelope mounted on and extending about each of the cut-out portions for receiving and encompassing a conduit member terminating at and within each of the cut-out portions, each envelope being disposed, constructed and arranged for directing one of the plurality of pressurized liquids onto a proximate area of the interior wall means thereof. The wall is cleaned by turning off the fluid flow but the blades continue to be rotationally driven whereby the wall is wiped clean by the blades which push the residue out the tubular members.

Claim 1
Independent Claim
326 words
An improved portable hand held mixer device for mixing at least two pressurized liquids distributed thereto comprising: support structure, a drive means mounted on said support structure, at least two conduit means mounted on said support structure, each of said conduit means terminating in an open end, valve means positioned along each of said conduit means for biasing said conduit means in a closed position, operative means mounted on said support structure for opening said valves whereby to permit the flow of said pressurized liquids, support structure attachment means, an elongated hollow tubular means having a longitudinal axis and an inner wall, said hollow tubular means having an open proximate end and an open distal end, said hollow tubular means being adapted and constructed to be secured to said support structure by said support structure attachment means, said proximate end having at least two cut-out portions generally symmetrically disposed about the longitudinal axis, wall means mounted on and extending about each of the cut-out portions at an acute angle with respect to said longitudinal axis, said open ends of each conduit means terminating proximate each of said wall means whereby said liquids when flowing from said open ends of said conduit means are directed to flow tangentially with respect to said inner wall, stirrer means mounted axially of said hollow tubular means and adapted and constructed to be driven by said drive means, said stirrer means having a plurality of elongated relatively thin blades each having a surface and each adapted and constructed to wipe at least a portion of the said inner wall when said stirrer is driven, said blades having distal free ends, said surfaces of said blades converging with the inner wall of the hollow tubular means in the direction of their distal free ends whereby the liquids introduced into said device are mixed along the inner wall and are propelled in a direction towards the distal end of said hollow tubular means.
Claim 2
Dependent Claim
326 words
An improved portable hand held mixer device for mixing at least two pressurized liquids distributed thereto comprising: support structure, a drive means mounted on said support structure, at least two conduit means mounted on said support structure, each of said conduit means terminating in an open end, valve means positioned along each of said conduit means for biasing said conduit means in a closed position, operative means mounted on said support structure for opening said valves whereby to permit the flow of said pressurized liquids, support structure attachment means, an elongated hollow tubular means having a longitudinal axis and an inner wall, said hollow tubular means having an open proximate end and an open distal end, said hollow tubular means being adapted and constructed to be secured to said support structure by said support structure attachment means, said proximate end having at least two cut-out portions generally symmetrically disposed about the longitudinal axis, wall means mounted on and extending about each of the cut-out portions at an acute angle with respect to said longitudinal axis, said open ends of each conduit means terminating proximate each of said wall means whereby said liquids when flowing from said open ends of said conduit means are directed to flow tangentially with respect to said inner wall, stirrer means mounted axially of said hollow tubular means and adapted and constructed to be driven by said drive means, said stirrer means having a plurality of elongated relatively thin blades each having a surface and each adapted and constructed to wipe at least a portion of the said inner wall when said stirrer is driven, said blades having distal free ends, said surfaces of said blades converging with the inner wall of the hollow tubular means in the direction of their distal free ends whereby the liquids introduced into said device are mixed along the inner wall and are propelled in a direction towards the distal end of said hollow tubular means.
Claim 3
Dependent Claim
20 words
The mixer device of claim 1 wherein each of the wall means is constructed integrally with the hollow tubular means.
Claim 4
Dependent Claim
37 words
The mixer device of claim 1 wherein the conduit means includes a section of flexible hose means and said valve means is a clamp means attached to said support means adapted and constructed to be manually operated.
Claim 5
Dependent Claim
121 words
The mixer device of claim 3 wherein the flexible hose means has a first radially longitudinally extending rib on one side of said flexible hose and a second radially extending rib on another side of said flexible hose, said clamp means including a first jaw means, said first jaw means having an undercut first longitudinally slot, said clamp means including a second jaw means, said second jaw means having an undercut second longitudinal slot, said first rib affixed in said first slot and said second rib affixed in said second slot whereby when said clamp is manually moved to open said flexible hose the said sides of said flexible hose remain affixed to said first jaw and said second jaw respectively.
Claim 6
Dependent Claim
35 words
The mixer device of claim 1 wherein the elongated hollow tubular means is of uniform diameter essentially throughout whereby said liquids after mixing are discharged from said distal opening of said elongated hollow tubular means.
