Mobile pneumatic apparatus for sucking and blowing fiber dust from textile machines
First Claim
1. In a pneumatic apparatus for removing particulate matter surrounding textile machines comprising, within a housing, a fan having on the suction side (upstream) thereof a first suction member and a second suction member, said housing defining respective passages for each of said suction members to the inlet of said fan, said passages being generally opposed to one another such that air being sucked through one of said passages runs in a generally opposite direction to air being sucked through the other of said passages, said fan having blower members on the pressure side (downstream) of said fan, first and second filter means within each of said respective passages for removing entrained particles from air being sucked through said passages, the improvement which comprises, within the respective passages, first and second shut-off members between said first and second filter means, respectively, and said fan;
- first and second blow ducts connecting the pressure side of side fan with the upstream said of said first and second shut-off members, respectively, said shut-off members being open and said blow ducts being closed during most of the operating time; and
means adapted to alternately close said first shut-off member while simultaneously opening said first blow duct for a brief interval during the operating time, and to close said second shut-off member while simultaneously opening said second blow duct for another brief interval during the operating time, so as to alternately and separately detach said particulate matter from each of said first and second filter means, while simultaneously continuing to pass an air stream through the other of said first and second filter means to thereby continue to pass an air stream free of said particulate matter through said fan and respective blow dust.

Abstract
A mobile pneumatic apparatus for removing lint, dust, dirt and debris from textile machinery and the locus thereof, having a fan which on one side thereof has a pair of suction conduits generally opposed to one another and has on the other side a blower member, each of the suction conduits having filter means for removal of lint, dust, dirt and debris, the apparatus improved by the inclusion of a normally open suction gate downstream of the filter means in each of the suction conduits which upon actuation closes to prevent air from passing therethrough, and a normally open by-pass conduit in each of the suction conduits downstream of the filter means, the branch conduits by-passing the gate and being directed toward the filter means. Means are provided to close the suction gate by opening the branch conduit gate. By actuation of the suction conduit gate and branch conduit gate in respect of one suction conduit, the air being passed through the other suction conduit functions to backblow the filter and allow the removal of the lint, dust, dirt and debris. A chute is provided with an openable and closable cute gate in general registry with the filter means for allowing the removal of the dust, dirt and debris being discharged from the filter. Several embodiments of the mobile pneumatic apparatus are disclosed, including one having a second branch conduit in association with each suction conduit, which conduit terminates upstream of the filter and assists in the removal of the lint, dust, dirt and debris impinged thereon.
