3 As a result of the embedding of the protuberances 20, 21 in the side walls and sidewalk slab of the catch basin as described above, these and the front wall of the catch basin are intcgrally united together, so that all parts of the catch basin expand and contract together. Additionally, the curb inlet casting is bonded thereto and is prevented from moving relative to the catch basin. The liorizontal pyptUlZerance 21- may be pro" vided with ali aperture 23, and the base piate I I may be provided with an aperture 19, positioned preferably near the end walls 14, 14. The apertures 23, 19 serve to increase the effectiveness o,@ the bonding of the curb 'Mlet casting to the catch basin and the sidewalk slab. They may also serve to additionally bond t4e, cW4,1@, in et casting I to the adjacent structures in the manner shown in Figs. 4 and 5.

Patented Aug. 28, 1951 21566,119 UNITED STATES PATENT OFFICE 2,566,119 CUBIR INLET CASTING De Witt S. Crocker, Springfield Gardens, N. Y. Application March 29, 1950, Serial No. 152,589 8 Claims. (Cl. 182-6) 2 This invention relates to curb ifflets for catch basing of the type shbwn in niy prior Patent No. 2,473,279, issued June 14, 1949. The general object of the curb inlet of the said patent and of this application Is to provide @5 a curb inlet casting which will integrally unite the side walls of the catch basin and the sidewalk slab thereof so that the inlet casting will move therewith as the concrete structure expands and contracts with temperature changes and will re10 rnain fixedly bonded thereto, and so that the cuib inlet casting itself will not move relatively to the wall and roof structure of the catch basin under said temperature changes. In the aforesaid patent, these ends are achieved 15 by providing the end walls of the inlet casting with a pair of protuberances extending outwardly and generally longitudinally of the casting and which present a vertical dimension substantially centered at the juncture of the side walls of the 20 catch basin and the sidewalk slab thereof, with the lower portions of the protuberances embedded in the side walls and with the upper portions of the protuberances embedded in said sidewalk slab. ?5 one of the objects of the present invention is to provide a curb inlet casting as described above, in which the said protuberances have modifled and improved or alternative constructions. Another object is to provide a curb inlet cast:@0 ing as described, implemented with means of additionally tying or,securing the casting to adjacent structures such as the catch basin, the sidew,,tlk slab, or the gutter grating. For the attaimnent of the foregoing and such 33 other objects of invention as may appear or be pointed out herein, I have shown several forms of my inventibn in the ace.ompanying drawings, wherein: Fig. I is a perspective view of the hnproved 40 curb inlet; Fig. 2 is an elevational section through the unpaved catch basin and curb inlet casting; Fig. 3 is a top view, partially in section on the line 3-3 of Mg. 2; 45 Fig. 4 is a fragmental elevational sectional view (similar to Fig. 2) but showing a modifled form; and Fig. 5 is a fragmental elevational sectional view, like Fi@. 4, showing a modification thereof. 50 The improved curb inlet casting, generally designated 10, comprises a base plate I I and an upper bar, 12, between which may be provided a plure@lity 6f intermediate partitions 13, integrally walt6d at- @their lower portions with base plate It 55 and at their upper portions with lorigitudinal bar 12. - Intermediate partitions 13, of which five are shown in Fig. 1, for exbinplification, provide a plurality of wide opei-iings 15 in front of the casting. The partitions 13@ as best seen in Figs. 1 and 2, are shown as of irregular triangular shape with the base thereof at the front of the ca,sting and with their apices 17 rearwardly disposed. These partitions are shown in the drawings as equally spaced from each other and from the end walls, 14, 14, of the casting. Projecting longitudinally (utwardly 6f the end walls 14, 14 are a vertically disposed flange or protuberance 20 and a horizon.tally disposed flange or protuberance 2 l@. The vertical protuberance 20 is sh n as located substantially at the medial vertica plane through end wall 14, Fig. 1 (see also Fig. 2) and the horizontal protuberance 21 is shown as located substantially at the medial horizoiital plane therethrough. Horizontal protuberance 21 ii shown a@s normal to the vertical one 20 and as extending rearwardly therefrom and as substantially coplanar to the medial horizontal plane through the apex 17 of the end waU. I The protuberances 2 i, 21 are so disposed and dimensioned that the lower portions there(>f are embedded in the side walls 9, 9 of the catch basin, see Figs. 4@5, and the upper portions thereof are embedded in the sidewalk slab S. The base I I of the improved curb inlet casting is disposed at the top surface of front wall 2 of the catch basin, this being substantially level with the subgrade 3, which is stepped down from the level of sidewalk slab 6@ The aforesaid front bar 12 of the improved curb casting constitutes the, curb at the sidewalk stepdown. The a-foresaid sub-grade 3 is further depressed below the roadway level 5 to form a gutter, which is covered by the gutter grating 4. The front of tlle catch-basin (where the curb inlet casting is placed) is completed by a front wall 2 of coneretei which is integrally united, see Fig. 3, with the side walls 9, 9. As best sliown in Fig. 2, the front wall 2 does not unite with the sidewalk slab 6 but presents its top surface spaced a short distance below the side-@vall,, slab. After the side walls 9, 9 of the catcl-i basiii aiid its front wall 2 are poured, the inlet castirig IO is placed in position along the front of the basin, with the base plate I I of the casting resting upon the aforesaid top surface of front Nvall 2. Thereafter, the sidewalk slab 6 is poured, to unite the casing in place.
