Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
152 words
An apparatus for cleaning a row of looms or the like comprising a high air velocity blower fan, means for continuously traveling said fan across the looms in said row, said fan discharging through a chamber having a plurality of fixed air discharge outlets, conduits communicating with each outlet, each conduit having a nozzle, said nozzles being spaced closely adjacent to the warp level of the loom, means for continuously oscillating said nozzles substantially perpendicular to the direction of fan travel and while said fan is moved across each successive loom, movable shutter means within said chamber opening and completely closing all of said outlets and a motor for rapidly moving said shutter means to completely stop the flow of air from said chamber to each of said outlets for brief closely spaced time periods to produce discrete, high velocity, closely spaced, transversely moving puffs of air from each of said nozzles.
Claim 2
Independent Claim
152 words
An apparatus for cleaning a row of looms or the like comprising a high air velocity blower fan, means for continuously traveling said fan across the looms in said row, said fan discharging through a chamber having a plurality of fixed air discharge outlets, conduits communicating with each outlet, each conduit having a nozzle, said nozzles being spaced closely adjacent to the warp level of the loom, means for continuously oscillating said nozzles substantially perpendicular to the direction of fan travel and while said fan is moved across each successive loom, movable shutter means within said chamber opening and completely closing all of said outlets and a motor for rapidly moving said shutter means to completely stop the flow of air from said chamber to each of said outlets for brief closely spaced time periods to produce discrete, high velocity, closely spaced, transversely moving puffs of air from each of said nozzles.
Claim 3
Dependent Claim
31 words
An apparatus as claimed in claim 1 in which said shutter means for stopping said flow of air through said outlets is provided with an orifice for each of said outlets.
Claim 4
Dependent Claim
34 words
An apparatus as claimed in claim 1 in which said outlets are arranged in alignment and said shutter means includes a plurality of spaced orifices, said shutter means being reciprocably mounted within said chamber.
Claim 5
Dependent Claim
67 words
An apparatus as claimed in claim 1 in which said outlets are arranged in alignment and said shutter means for stopping said flow of air through said outlets is a rotatable cylinder in said air chamber having a spaced orifice therein for each of said outlets and means driven by said motor for rotating said cylinder to move said orifices rapidly past the outlets in said chamber.
