CURB INLET CASTING.
De Witt Saxton Cracker, Springfield Gardens, N. Y.
Original No. 2,473,279, dated June 14, 1949, Se-

6 Claims. (01. 182-6) Matter enclosed in heavy brackets appears in the original patent but forms no part of thi reissue specification; matter printed in italics indicates the additions made by reissue This invention relates to curb inlets for catch basins for road drainage. g
Such inlets are provided by incorporating into the curb which separates the elevated sidewalk from the road, a casting which opens the road gutter to a catch or drainage concrete lined basin which underlies the sidewalk. The casting is held in position by being bonded to they immediately adjacent portions of such construction. Experience has proven that this bond is an element of weakness in that it breaks readily and permits the casting to move away from the sections to which it has been bonded. It is not an unusual occurrence for the casting to project outwardly beyond the curb as much as 4",.to present a hazardous obstruction to trafilc. I attribute this weakness to the peculiarity that the concrete sections to which the casting is bonded do not contract as fully as they expand. This explains the gradual decrease in the width of the separating spaces generally provided between sectionsof a roadbed for expansion, until the space closes and any further expansion of the roadbed sections will cause the road to break up. Thisxis a major determining factor in the life of the roadbed.
It is this peculiarity in the contraction and expansion of the sections, coupled with the fact that the curb inlet casting tends not'to' follow the contraction and expansion of thesections to which it is bonded or secured, which in my opinion destroys this bond so that the curb requires frequent rebuilding and the casting resetting during the life of the road, with the consequent inconvenience and increase in road maintenance cost.
The general object of my invention is a novel provision for preventing the separation of; the curb inlet casting from the catch basin wall structure.
Another object of my invention is a novel-provision for so securing the cunb inlet. castingsto the catch basin wall structure that the inlet cast-' ing will move therewith as the wall structure expands and contracts with temperature changes and will remain fixedly bonded thereto and inseparable therefrom as long as the wall structure maintains its integrity.
For the attainment of these objects and such other objects as will be hereinafter pointed out,
I have illustrated embodiments of my invention.
in the drawings, wherein: I
Fig. 1 is a cross-section through a catch basin, the sidewalk which it underlies. and the adjacent on an enlarged scale;
Fig. 2 is a section taken on line 2-2 of Fig. 1,
Fig. 3 is a perspective of the curb inlet casting of Figs. 1 and 2;
Fig. 4 is a perspective, on an enlarged scale, of the one end of the curb casting inlet of Fig. 3; and
Fig. 5 shows a modification.
Upon reference to Fig. 1, it will be observed that I here show a transverse cross-section through the gutter slab and the adjacent sidewalk II which overlies the catch or drainage basinv I 2 whose front and back and side walls are numbered l3, I4, l5 and I6, respectively, and whose bottom is numbered l8. Access to basin l2 may be had through a sidewalk openingclosed by manhole cover I9. The inner portion of the gutter slab 20 tapers to provide a gutter 22 into which the water drains from the roadway and along which it flows to the curb inlet and from there into the basin I2.
The curb inlet casting is shown as comprising a front wall and a bottom 3|. The front wall. 3!! is provided with relatively large openings 32 across its length, separated by relatively narrow partitions 33 to provide maximum drainage clear-- ance therethr'ough. The partitions are extended. rearwardly to form end walls 35 and 36 and thetriangular fins 31 which define a plurality of passageways whose effect is to distribute the road.
water across the width of the basin l 2. The fins: 3i and the end walls 35 and 35 are shown for illustrative purposes, as all of the same dimensions and contours and as integral with the bottom 3! for its full depth. The front wall extends below 'of the front face.
I provide the end walls 35 and 36 of the casting of Fig. 3 with [the outwardly extending and vertically elongated flanges 40, approximately 6" long and positioned centrally of the height and :."-als"o of the depth of these walls] a pair of protuberanc'es 40, 40 extending outwardly and generally longitudinally of the casting. The protuberances 40, 40 have a vertical dimension substantially centered at the juncture of the side " walls 15, 16 and sidewalk slab 11 of the catch basin with the lower portions of protuberances 40, 40 embedded in said side walls 15, 1b and with the upper portions of the protuberances embedded in'sa id sidewalk slab 11.
