' SEWER-INLET DEVICE.

Application filed March 14, 1927. Serial No. 175,307.

My invention relates to a new and useful sewer inlet device and more particularly to a metallic sewer inlet having readily detachable closures or lids, and an inlet device which will afford the greatest degree of safety to pedestrians passing over the same and one which will prevent the dislodgement of the inlet device as a whole and which will minimize the danger of accidental removal of the detachable lids and the losses due tosuch accidental removal.

With the above ends in view, my invention consists of a metallic housing, preferably made of cast iron or the like, and comprising an upper, substantially horizontal wall, the rear portion of which is rectangular or any other suitable shape, while the front edge of which is of a shape to conform to the curb line, that is, either curved or straight, and having a suitable opposed locking shoulder and forwardly converging inclined edges adapted to interlock with the curb stones, so as to prevent dislodgement of the inlet device.

The novel inlet device of my invention further consists of suitable rear and side walls, depending downwardly from said upper horizontal wall, spaced inwardly from the side and rear edges thereof, and adapted to be embedded in masonry or concrete work surrounding said inlet device, so as to maintain the latter firmly within the side-walk or the like.

My invention further consists in providing one or several openings in the upper horizontal wall of the inlet, and suitable inwardly projecting horizontal flanges at the lower edge of said wall and said openings, and circular closure members adapted to fit within said openings, and to be supported upon the inwardly projecting flanges therein, of a thickness sufficiently great relative to the diameter thereof, so as to prevent any accidental displacement of the said closure from the openings, that is, of such depth relative to the diameter that it can not be removed from the opening merely by raising or tilting up one side thereof only.

For the purpose of illustrating my invention, I have shown in the accompanying drawings a form thereof, which is at pres .ent preferred by me, since it will give in practice, satisfactory and reliable results, although it is to be understood that the various instrumentalities of which my invention consists can be variously arranged and organized and that my invention is not limited to the precise arrangement and organization of these instrumentalities as herein shown and described.

Referring to the drawings in which like reference characters indicate like parts Figure 1 represents a top plan View of a sewer inlet device embodying my invention, shown embedded in a side Walk.

Figure 2 represents a bottom plan View of the same.

Figure 3 represents a section on line 33 of Figure 1.

Figure 4 represents a section on line 1-4 of Figure 1.

Figure 5 illustrates the interlocking of the closure with the edges of the opening in the inlet device, when said closure is tilted, or raised on one side only.

Figure 6 represents the manner of removing the closure from the opening, by raising the same on both sides.

In carrying out my invention, I provide an upper horizontal wall 1, of suitable thickness, havin suitable rear and side edges 2 and 3, and having the front edge t thereof of shape, so as to conform to the general contour of the curb line. In the particular illustration shown in the drawings, the front edge 1 is curved so as to adapt the inlet device for use at a street corner.

Intermediate of the front edge 4 and said side edges 3, suitable rearward shoulders 5 are provided, projecting outwardly from either side edges 3, and forwardly converging inclined edge portion 6, intermediate of the curved shoulder portion 5 and the front edge 4.

The upper horizontal wall 1 may be provided with one or several openings 7, of any suitable diameter, and suitable horizontally and inwardly projecting supporting flanges 8, at the lower edges of said openings 7, in order to afford support for the corresponding lids or closures 9. The depth of the openings 7, that is, the distance of the upper surface of, the wall 1, to the upper surface of the flange 8, is sufficiently great with respect to the diameter of the opening, so that the circular lid or closure 9, fitting relatively snuglywithin the opening 7, may not be withdrawn or raised therefrom by tilting or by raising only one edge thereof, as indicated in Figure 5, but only by a substantially parallel upward movement of the entire lid, as indicated in Figure 6. By this construction, not only is the unauthorized removal of the closure 9 made more dilficult, but the accidental removal or the displacement thereof from the opening 7 is practically eliminated.

Suitable recesses 10 may be provided at two diametrically opposed points along the periphery of the circular lid or closure 9, in order to permit of the insertion of suitable hooks or other implements 11 beneath the lid, at two diametrically opposed points, so as to permit of the lifting and removal of the lid or closure.

Surrounding the opening or openings 7, on the sides and in the rear, suitable downwardly extending flanges or walls 12 and 13 are provided, preferably formed integrally with the upper Wall 1, and spaced a suitable distance from the respective edges thereof. The lower edges of the side and rear walls 12 and 13 are suitably arched as indicated at 14.

In applying or mounting the outlet device of my novel construction in the pavement, above the vertical well or passageway 15 leading into the sewer, the front edge 4 of the outlet device is positioned in alignment with the curb line, and the curb stones 16 on either side are brought into abutting relation with the forwardly converging inclined edges 6 of the u per wall 1. The horizontal upper wall 1 is t en supported directly upon the masonry work by the laterally projecting or overhanging free edge portions 17 thereon, as indicated in Figures 3 and 4:, with the downwardly depending side and rear walls 12 and 13, confined between the rear and front walls 18 and 19 of the Well 15, and the side walls 20 thereof. The front portion 22 of the upper horizontal wall 1 overhangs a continuation of the pavement 21, and forms therewith a horizontal passageway which communicates with vertical well 15.

It will thus be seen that by my novel construction in a sewer inlet device, not only is the inlet device securely anchored in the masonry and pavement etween the curb stones, so as to prevent the same from working loose or from being dislodged, but due to the relatively deep openin s and correspondingly deep closures or lids, disposed within said openings, the accidental removal of said closures or lids is practically eliminated, thereby providing a sewer inlet with a minimum of hazards usually present in devices of this-character.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is A sewer inlet device of the character stated, comprising a frame having an upper horizontal wall, having forwardly converging inclined side edge portions adjacent the front edge thereof, and having rearward shoulders intermediate said inclined side edge portions and the rear ed e thereof, an aperture extending through said upper wall of substantial depth relatively to its diameter, an annular lateral inwardly projecting flange extending around the lower edge of said aperture, a closure member fitting relatively snugly within said aperture and supported upon said flan e with its upper surface substantially flus with the upper surface of said wall, and provided with a pendant peripheral male counterbore seated within said aperture, diametrically opposed recesses in the periphery of said closure for the reception of lifting hooks, rear and parallel side pendant walls carried by said upper horizontal wall, extending substantially parallel to the rear and side edges thereof, and spaced inwardly therefrom a suitable distance, so as to form overhanging lateral flange portions of said upper horizontal wall, exterior of said rear and side walls whereby the inlet device may be sup orted on suitable masonry, said downward y depending side and rear walls being adapted to be confined between the upright wall of the masonry well, leading to the sewer, said forwardly converging inclined edges of said upper horizontal wall being adapted to be confined between and to interlock with the two opposed curbstones.
