Feb. 14, 1939. B. H` LANT'Z NONCLOGGING CATCH BASIN GRATING Filed Jan. l5, 1938 INVENTOR.
BY K77.9,
ATTORNEY.`
Patented Feb. 14, 1939 UNITED STATES PATENT oFFicE 7 Claims.
My invention relates to improvements in nonclogging catch basin grating and it more especially consists of the features pointed out in the annexed claims. I
The purpose of my linvention is to provide a simple non-clogging grating for catch basins in which there are no obstructing bars of any kind whatever; that provides tapering bars that are unconnected at their free ends; that also provides tapering openings between the bars or 1ingers; and that has the bars positioned at an angle to the adjacent curb in the direction of the natural water flow along the gutter. An outstanding feature of my invention is the entire freedom between the fingers for the passage of leaves etc. due to the tapering of the fingers toward their outer ends and the gradually widening openings between the fingers. 'Ihis causes the running water to free any leaves or rubbish that may accumulate at the base of the fingers. If the opening between the fingers were formed with parallel sides any accumulations on the fingers would not be self releasing. This condition is universally present in gratings that have been provided heretofore.
With these and other ends in view I illustrate in the accompanying drawing such instances of adaptation as will disclose the broad feature of the invention without limiting myself to the specie details shown thereon and described herein.
Fig. l is a top plan View of a grating installed over a catch basin.
Fig. 2 is a view similar to Fig. 1 with the curb removed and the beneath parts in section.
Fig. 3 is an elevation in section through an opening between adjacent fingers.
Fig. 4 is a diagrammatic view of a pair of gratings that may be used on the center line of alleys etc.
Fig. 5 is a cross section on line 5 5 of Fig. 1 of one of the fingers.
Catch basins may be provided with a supe' porting casing I with an open top and a side extension 2 and a bottom 3 is formed integral with the casing. A drain opening 4 is made in the bottom 3. This may be connected with the sewer in any conventional manner. A shoulder 5 is formed on the inner face of the casing to provide a seat for the grating.
The grating comprisesa one piece casting or a unitary composite structure that has the ends I approximately parallel to each other andthe one lengthwise edge 8 integral with the ends. Tapering fingers 9 project at an angle from the edge 8, forming a gradually widening opening I0 between the iingers. The fingers may be somewhat rounded in cross section and they have a curvilinear contour in a lengthwise direction causing them to be slightly tapering in a horizontal and vertical direction. 5
The grating may be positioned on the shoulder 5 on the inside of the casing in any relation. It may be reversed end for end for any side of a street and the angle of the ngers is adaptable to whatever direction the street may be inclined by simply turning the grating up side down. Limiting abutments are formed at the ends of the shoulder 5 to hold the grating cover in place (Fig. 2).
By reason of these features the grating is universally applicable to any and all varying conditions that may be found in surface drainage for storm or other conditions.
The grating with slight modifications may be adapted to the center or other line of alleys by combining two gratings as shown in Fig. 4 wherein the iingers of one half terminate between the ends of thefingers of the other half. The arrows shown on Figures 1 and 4 indicate the direction of water ow. As shown on Figs. 1 and 3 the fingers 9 project to one side farther than the edges of the grating so as to terminate beneath the curb opening to thereby guard the catch basin against the admission of sticks etc. It is obvious that the parts 1 and 8 of Fig. 4 may if desired be cast in one piece.
I am not limited as to the dimensions of the fingers, their angle etc., nor to the number of fingers on a given grating nor to the sizes of the gratings or drain covers. The openings between the fingers taper in an opposite direction to the taper of the fingers.
I have found in actual practice that the best results are secured when the iingers project in the direction of the liow of water along the gutter, which, should the catch basin be located at an intersection where the flow of water is from two different directions, the lingers on one portion of the grating may project in a different direction from the ngers along the other portion of the grating, thus accommodating the grating to special conditions of this kind. It is immaterial whether the fingers are absolutely straightthroughout their length as it is obvious that they might be curved to `conform to the curve flow of water according to the inclination of the street and the position of the catch basin.
What I claim is:
1. In non-cloggable catch basin or drain cover,
a suitable support, an integral casting constltuting the grating formed with a reversible base having tapering fingers and openings between the ngers that taper in the opposite direction, the fingers and openings being disposed at an angle to the base.
2. A drain cover grating comprising a single member, a base thereof, angularly disposed fingers projecting therefrom forming angularly disposed openings between the ngers, and a tapering contour to the ngers lengthwise thereof, said iingers being at an angle less than 90 to the base.
3. A non-cloggable drain cover, comprising a unitary casing positioned adjacent a curb, a grating cover on the casing comprising a plurality of tapering ngers projecting at oneV side thereof forming tapered openings between the iingers that are the reverse of the taper of the fingers, said fingers being disposed at an angle to an edge of the casing and the curb.
4. A drainage cover comprising a unitary member having a continuous edge, angularly shaped iingers projecting therefrom, an opening between each pair of ngers that is closed at one end and not closed adjacent the continuous edge, anda suitable casing having an opening leading to a drain for supporting the cover.
5. A universally adaptable drain cover comprising a horizontally positionable unitary casting, a plurality of ngers projecting'therefrom on the same plane and at an angle to its edges,
the fingers being tapered toward their free ends and rounded in cross section, said fingers having openings between them that taper in a reverse direction.
6. A non-cloggable catch basin comprising a casing having an outlet opening, a supporting shoulder projecting inwardly from the walls of the casing, limiting abutments on the shoulder, a unitary grating positioned on the shoulder and held thereon by the abutments, a plurality of tapering fingers projecting from an edge of the grating in different directions, said fingers being vformed' tapering lengthwise thereof and having openings formed between the fingers which taper in a reverse direction.
7. A non-cloggable catch basin, comprising a casing having an inside shoulder to form a support, a iingered reversible grating resting on the shoulder, a curved extension of the casing in line with the curb which projects toward the grating and terminates above the grating fingers so that the fingers extend thereunder, said casing being provided with an exit opening beneath the curved projection, said grating comprising tapering fingers projecting from a continuous edge of the grating, the fingers being Aspaced apart to form openings therebetween which taper in a reverse direction from the taper of the fingers.
