i Application led October 15, 1828. Seria1"NoiA141,687.
My invention relates to improvementsin catch basins, and .more particularly to the type which is intended to catch Adbris or,
meet varying conditions, and is economical to install and maintain `and willfbeghighly satisfactory and sanitary in use.
vMy invention will be `best understoodby referrin to` the .accom anying drawings which ilustrate a form o my invention and to the following descri tion inthe accompanying specification. n the'drawings: Fig. 1 represents a side elevation" of a basin showingfits `relation toor its setting in the ground; l FiggQ is a section on the line 'IL-II of Fig. 1; andFig. 3 is acentral cross sectional elevation through the outlet.
Like reference characters indicate like parts in the several views.
Referring tothe drawings by characters of reference, my improved catchbasin in the embodiment herein illustrated, comprises a bottom tank basin member `10, containingl a `discharge `outlet or a sewer inlet 11"an a` trash orffilter box. Above thisbottom` member and resting thereon is an intermediate section or body portion 12, the sides or walls of which are a vertical continuation `of the walls of the basin member. A
partially tapering collar-like reducing section 13 rests on this intermediate portion and a top or inlet member whichis a casting 14., surmonnts the whole structure. Theintermediate casting 12 mayl be "of any desired length and may be in `one or moreQpieces. The casting 12 may be omitted entirelywhere it is not necessary to secure `the "requiredf drop -from the sidewalk and gutter level to the sewer inlet level, which level must accommodate itself in some manner to the level of the sewer invert as arranged by the engineers. 4The advantage of using a separate piece 12 is great where the street levelis changed after installation of the basin.
The bottom section 10 may be cylindrical 0r square in plan, or it may have any desired shape. There are no sharp corners in this casting which would make the construction or casting operation diicult, or
Lfrequent cleaning operations impede free flow by accumulations of solid material 1n thecorners of thebasin.
ing oflthis catch basin permits a large water storage space `which permits a better trappingtor sealing etl'ect against sewer" an'. This large capacity will also require less and at the same time will slowdown the passage of water through the basin which aids in precipitating sediment in this part of `the sewage system from which it may be more easily removed than from the street system.
Eachsection member of `thiscatch lbasin has in itsqupper ed e a continuous recess or groove to accommodate and retain the edge of` the upper" section which extends down# wardly into this groove. The positioning of a supporting edge in this recess will-seal the joint between each of the various sections to prevent the entry of solids. Flange lugs lcooperate to secure together the sections of ther catch basin and are perforated TheV bottom casting therefore may easily be cleaned. In additionit has a tendency to "scour 'itself relatively clean.` The use of a suspended filter box` in the lowermost castfor thepassage of retainingbolts to provide ari 'd'construction f e bottom casting `10 is formed with a discharge outlet 11 cast integral with one of the narrower sides. o Abafile plate 18 depends from an inwardly extendingflange 1l9 and bothare integral withthe body of the basin. The baille 18 extends entirely across-thebasin` and is" spaced infront of and at a sli htdistanceiromthe outlet 11 and exten ssome distance below the outlet 11 `to forma sealing trap;` This baffle plate thas a lug or flange 20 turned inwardly or away from` the outlet nozzle to support an imperforateyplate 21. This plate 21 is mounted along the bottom edge and adj acentlthe center of the baille platey18 and Iits opposed short edge rests on a rib or, flange 2 2" extending from the wall of the `castinglO opposite the `battle plate 18; Flanges extend from the longer sides of the basin and assist in supporting the baille plate, at its outer extremit1es. These flanges carry L-shaped members or castings 23 which serve as gratings or grids for the filter box and are flanged at their lower exterlnities to support the bottom plate 21 of the filter box. These L-shaped gratings are preferably rigidly bolted to the side flanges, but are not secured to the bottom plate which may be easily removed with proper tools to provide access to the lower portion of the catch basin. Thus the plate 21 is tightly fitted against its supports and forms a satisfactory closure to the filter box in t-he basin portion. This strains out straws and sticks which might obstruct the sewer by lodgment therein. Removal of this matter from the filter box is more readily accomplished than would be possible from the sewer and ready removal of the bottom plate 21 provides easy access to the catch basin, as noted above.
The upper or inlet member 14 has a manhole cover 25 recessed into its head section in the usual manner. As shown, this cover is a part of the sidewalk and may have the usual or any suitable structure affording easy access to the interior of the catch basin.
. A gutter grating 26 is recessed into the gutter portion of the catch basin at the street level and may be arranged to be readily removable by the proper parties A curb grating 27 of any desired structure or formation is secured into the curb section of the catch basin inlet. These covers or gratings have the usual function and uses of permittingready accessr to the catch basin proper. At the same time they permit the inflow of water while keeping relative large objects from the basin.
Having set forth my invention, I claim:
1. In a catch basin, an inlet member, and an outlet member joined thereto, said outlet member having inwardly extending flangesv for supporting a filter box and sections supported on said flanges forming avfilter box said filter box having a removable imperforate bottom and opposing removable perforated side walls. Y
2. In a catch basin, an inlet' member, and an outlet member joined thereto, said outlet member having inwardly extending flanges' for su porting a filter box and sections supporte on said flan es forming a filter box, said filter box having a removable imperforate bottom and opposing removable perforated side walls, the front and rear walls Y of the filter box being integral parts of the basin member. Y
3. In a catch basin, an inlet member, and an outlet member temporarily connected together, said outlet member having a sewer inlet extension integral therewith, a downwardly extending baille plate opposing said sewer inlet, spaced at a distance therefrom, and flanged inwardly, a ledge on the opposmg wall of said basin, a plate supported between said flange and ledge to, form the.
bottom of a filter box, and perforated memberssupported by and spaced from the side walls of said outlet member and engaging said plate to complete the filter box.
4. In a catch basin, an outlet member and an inlet member, removably connected thereto,rsaid outlet memberhaving a sewer inlet extension inte ral therewith, a downwardly extending ba e plate opposing said sewer inlet and spaced therefrom, the lower end of ysaid baille being below the vsewer inlet level to form a trap and flanged inwardly, a
ledge on the opposing wall of said basin, a plate supported between said flange and ledge to form the bottom of a filter box and perforated members, su ported byV andV spaced from the side w s of said outlet member and engaging said plate to complete the filter box.
5. In a catch basin, an inlet member, and
an outlet member temporarilyconnected together, said outlet member havinga sewer inlet extension integralV therewith, a downwardly extending baille plate opposing said sewer inlet, spaced at a distance therefrom,
and flanged inwardly, a ledge on the opposing wall of said basin, a plate supported between said flange and ledge to form the'bottom of a filter box, and perforated plates spaced from and bolted to the side Walls of said outlet member and su porting the edges of said plate to complete ture. l Y Y y6.
