Abstract
A filter candle, especially for gas equipment, includes a plurality of cooperatively associated tubular mutually telescopically engageable filter-candle segments. Each segment is comprised of an inherently dimensionally stable material. Each segment has structure for supporting each segment relative to the other segments, and additional structure for limiting the movement thereof relative to the associated segment. Structure is also provided for releaseably supporting the segments together as a filter candle.
Claims37
Filter candle, especially for gas equipment, comprising:
- a plurality of cooperatively associated tubular mutually telescopically engaging filter-candle segments, each segment comprised of an inherently dimensionally stable material and each segment including means for supporting each segment relative to the other segment and including means for limiting the movement thereof relative to the other associated segment and means for releasably supporting said segments together as a filter candle.
Filter candle, comprising:
- a) at least first and second tubular dimensionally stable hollow segments, each segment having opposite first and second ends and said segments being telescopically engageable one to another between first and second orientations;
- b) means operably associated with said segments for supporting each segment relative to another segment and including means for releasably supporting the second end of said first segment to the first end of said second segment as a filter-candle and for limiting the movement of said segments;
- and
- c) means closing the second end of said second segment so that said segments are telescoped and form an elongated tubular body which is open at one end and closed at the opposite end.
A filter assembly, comprising:
- a) a apertured support;
- b) a first dimensionally stable tubular open ended segment, said first tubular segment being disposed within the aperture of said support and having a first end portion disposed about the aperture for maintaining said first tubular segment in position and an opposite second end portion extending therefrom;
- and,
- c) a second dimensionally stable tubular segment, said second tubular segment has a first opened end portion releasably engaging said first tubular segment second end portion for supporting said first tubular segment relative to said second tubular segment and for limiting movement of said tubular segments relative to each other and an opposite second end portion closing said second tubular segment and said second tubular segment is telescopically engaging said first tubular segment for engaging and supporting said end portions and said segments as a filter candle.
