Abstract
A holding apparatus includes an anchor plate including upper and lower sections and a core member sandwiched medially of the upper and lower sections. A bore passes through the upper and lower sections and the core member. A plurality of elongated support legs are connected to the anchor plate and are adaptable along opposing radial paths. An elongated support rod is included for axially receiving and supporting the filter. The support rod is engageable with the anchor plate such that the support rod becomes aligned along a vertical plane while extending away from the anchor plate. The apparatus further includes a locking wedge having an inverted conical shape and an elongated sleeve formed therein for attaching to the support rod. The locking wedge engages the filter such that the filter becomes positioned between the locking wedge and the anchor plate. The locking wedge includes threadably adjustable spherical gripping members.
