Air cleaning system
First Claim
1. An automatic gas-moved cleaning device comprising a source of gas, a movable first cylindrical means (2) laterally movable upon a second cylindrical means (1), said first cylindrical means containing a fixed body (7) having adjacent its opposite sides gastight chambers (3) and (3'"'"'), said chambers adapted to be alternately expanded and contracted with entrance of gas therein, when one of said chambers expands as filled with gas the other chamber adapted to be reduced in volume, said first cylindrical means (2) adapted to be continuously moved laterally along said second cylindrical means (1) as gas fills each chamber alternately, at least one nozzle (21) in gas flow relation with each of said chambers and adapted to permit gas to continuously flow out said nozzles from the interior of each of said chambers, said body (7) comprising means to direct gas flow alternately into each chamber and thereby cause first cylinder means (2) to move laterally back and forth and wherein the same source of gas is used to provide gas jets exiting said nozzles (21) and to provide movement of first cylindrical means (2) back and forth along the lateral periphery of a roller (29) to be cleaned.

- 1. An automatic gas-moved cleaning device comprising a source of gas, a movable first cylindrical means (2) laterally movable upon a second cylindrical means (1), said first cylindrical means containing a fixed body (7) having adjacent its opposite sides gastight chambers (3) and (3'"'"'), said chambers adapted to be alternately expanded and contracted with entrance of gas therein, when one of said chambers expands as filled with gas the other chamber adapted to be reduced in volume, said first cylindrical means (2) adapted to be continuously moved laterally along said second cylindrical means (1) as gas fills each chamber alternately, at least one nozzle (21) in gas flow relation with each of said chambers and adapted to permit gas to continuously flow out said nozzles from the interior of each of said chambers, said body (7) comprising means to direct gas flow alternately into each chamber and thereby cause first cylinder means (2) to move laterally back and forth and wherein the same source of gas is used to provide gas jets exiting said nozzles (21) and to provide movement of first cylindrical means (2) back and forth along the lateral periphery of a roller (29) to be cleaned.
- 5. An automatic gas-moved cleaning device comprising a source of gas, a first movable cylindrical means (2) and a second cylindrical means (1), said source of gas being the only means providing gas to the device and adapted to both move said first movable cylindrical means and provide gas jets exiting said device, said first cylindrical means containing a fixed body (7) having immediately adjacent its right and left sides substantially gastight chambers (3) and (3'"'"'), said chambers adapted to receive said gas in an alternate manner thereby moving said movable cylindrical means in a direction opposite to either the right and left side as it is filled with gas means whereby when one of said chambers expands as it fills with gas the other chamber is adapted to be reduced by movement of said movable cylindrical means, at least one outlet nozzle (21) in gas flow connection with each of said chambers and adapted to permit gas to continuously flow out said nozzles in a jet stream of sufficient force to permit cleaning of an adjacent device (29) said body (7) comprising means to direct gas flow alternately into each chamber and thereby cause said first cylindrical means (2) to continuously move laterally from right to left and subsequently left to right and wherein the same source of gas is used to provide gas jets exiting said nozzles and to provide movement of first cylindrical means (2) back and forth along the lateral periphery of a roller (29) to be cleaned.
