20. The combination of a sewer basket with a basket support for retaining said sewer basket at a selected level within a generally vertical sewer channel, said sewer channel defining a channel inner surface and a sewer aperture leading thereinto, said sewer basket including at least two basket units individually positionable generally adjacent each other in a filtering configuration within said sewer channel for forming a filtering surface extending at least partially across said sewer channel at said selected level; said basket support including an anchoring section for anchoring said basket support to said channel inner surface and a basket supporting section for allowing said basket units to be abuttingly rested on said basket support, said basket supporting section including an intermediate section, said intermediate section including at least two intermediate segments positonable adjacent each other for allowing said intermediate section to abuttingly support said basket segments in said filtering configuration, said basket supporting section also including an intermediate-to-anchoring section supporting structure for supporting said intermediate section in a predetermined relationship relative to said anchoring section; whereby when said anchoring section is attached to said channel inner surface said intermediate section is mountable on said intermediate-to-anchoring section and said basket units are mountable on said intermediate segments in said filtering configuration.
FIG. 3 is an end view of the support frame boll and nuts system taken along line 3—3 of FIG. 2 to expand the support frame against the sewer wall and used for the embodiments of FIGS. 2 and 2a;
FIG. 6 is a cross-section taken along line 6—6 of FIG. 2b;
FIG. 7 is a view similar to FIG. 1, showing another embodiment of a basket and support assembly according to the present invention in a sewer pipe having a small opening relative to the cross-section of the vertical pipe, and showing a different basket support anchored to the sewer pipe;
Referring to FIG. 1, there is shown a basket 2 abuttingly supported by a basket support 4 within the upper part of a vertical sewer pipe P or channel which opens at street level and has a channel peripheral wall defining an interior peripheral surface, the street being indicated at S and normally closed by a manhole cover M. The basket 2 includes a basket frame 6 which is circular and formed of a cylindrical flat strip; a filter screen 8 closes the basket frame 6 being secured thereto all around the lower edge thereof. A straight crossbar 10 is secured to the basket frame 6 and extends across the same; the crossbar 10 overlies the filter screen 8 as shown in FIG. 5. The crossbar 10a may be angled at its center as shown at 10a for basket 2a in FIG. 5a. An upright sleeve 12 or 12a is secured to the center of the crossbar 10 or 10a, the sleeve terminating at approximately the top edge of the basket frame 6 or 6a as shown in FIGS. 5 and 5a respectively. A post or rod 14 has its lower end 18 fitted within sleeve 12 or 12a by means of a cotter pin 18 as shown in FIG. 4. As shown in FIG. 4a, sleeve 12 can be replaced by an eye 22 to be releasably engaged by a hook 24 formed at the lower end of post 14a. The top end of the post 14 is formed with a handle 20 which normally extends just underneath the manhole cover, for easy removal of the filled basket and for re-inserting the same in operative position within the sewer pipe P.
If the sewer pipe P has a quadrilateral cross-section as is often found in sewer pipe manholes, then the basket and its basket support can be shaped to fit the cross-sectional shape of the sewer pipe, as shown in FIG. 2a. There is shown a basket frame 2a of rectangular cross-sectional shape, formed as in the previous embodiment of a rectangular flat strip frame 6a to the under side of which is secured a similarly shaped filter screen 8a which is overlaid by crossbar 10. Here again a post 14 is provided with a handle 20 at its upper end and a lower end adapted to be connected to the center of the crossbar 10 as by the systems of the FIG. 4 or 4a.
Referring to FIG. 7, there is shown another embodiment of a removable sewer basket 2c or filtering structure including a plurality of, at least two, removable filter units 80 or filtering components preferably releasably supported in a filtering configuration by an intermediate support 60 or supporting structure, itself supported in a supporting configuration by a basket support 4c or anchoring structure at a predetermined level within a vertical sewer pipe P having an opening or aperture at a street level S of a substantially small size relative to its cross-section at the predetermined level. The basket support 4c includes a plurality of, preferably at least three, right angle brackets 26c. Each bracket 26c has a lateral wall 72 or anchoring section to be secured against the interior surface of the sewer pipe P via a fastening device, preferably a concrete type screw 74, at the selected level and a top wall 76 or abutting section to abuttingly support the intermediate support 60 thereon in the supporting configuration.
Alternatively, the crossbar 82 has a through hole 84 slidably (freely) engaged by the post 91. The nut 102a is adjustably and releasably secured to the thread 95 below the through hole 84, as illustrated in FIG. 9. Additionally, an upper nut 104 could engage the thread 95 above the through hole 84 to limit the height of the handle 93 relative to the frame 81 when the filter unit 80′ is in rest position, as shown in the two filter units 80′ on the left of FIG. 9.
When the size of the channel aperture is relatively small, both the basket support 4d and the intermediate support 60 are preferably made out of at least two adjacent filtering components 38a and supporting parts, segments or components 62 respectively, as illustrated in FIG. 9. The two parts 62 abuttingly rest on the engaging ears 34 of the strip 26 or abutting section of the anchoring structure, or basket support 4d in a safe and stable position. To ensure proper positioning and leveling of the filter units 80′ on the parts 62, a common positioning member 65, preferably a small flat linking plate secured to one of the parts 62 and located at the overall center area of the intermediate support 60 overlying and freely abutting on the other part 62, is provided as a common rest surface.
To improve the stability of the filter units 80,80′, each part 62 has a flat lattice shape. Each part 62 or supporting component includes a supporting component peripheral rim and a supporting component crossbar extending at least partially across the supporting component rim for at least partially supporting a corresponding filtering component 38a. The supporting component rims are configured and sized to abuttingly rest on the abutting section 34 or engaging ears of the anchoring structure 4,4d. Each supporting component 62 has a generally hemi-disc configuration defining a rim arcuate segment extending integrally into a rim rectilinear segment The rim rectilinear segment of each supporting component 62 is positionable in an adjacent relationship relative to each other so that the supporting components 62 together define a generally disc-shaped configuration of the intermediate or supporting structure 60.
