DRAIN PROTECTOR Filed Aug. 1, 1960 INVENTOR. 42 Alice R. Alberico United States Patent 3,121,682 DRAIN PRGTECTOR Alice R. Alhcrieo, 431 Myra Way, San Francisco 27, Calif. Filed Aug. 1, 1960, Ser. No. 46,526 2 Claims. (Ci. 210-166) This invention relates to a new and improved drain protector, and more particularly to a protector replacing or placed over the cover plate of a conventional storm drain, so constructed as to prevent leaves and other debris from clogging the opening of the drain.
A conventional storm drain installed in sidewalk, floors, driveways, and other similar locations is a square or rectangular plate of castiron having a pattern of holes through which water flows to a storm sewer connection. Such drains and their plates are very commonly used. One of the difliculties encountered by householders and the like is the fact that leaves from trees, garden debris and similar matter tends to clog the drain holes and this can create a serious problem in the event of severe rainfall. The present invention has for its principal purpose the provision of means for keeping such leaves, etc. at a distance from the drain opening.
Still another purpose of the invention is to provide a strainer which permits the flow of water to the drain, but catches leaves and the like in such manner that the leaves may periodically be cleaned away without difficulty.
Still another feature of the invention is the fact that the strainer which prevents leaves from accumulating to clog the drain openings is of relative low height so that, in emergencies, where a considerable quantity of water is backed up around the drain and where leaves have accumulated in sufficient quantity to clog the protector, the fiow of water may pass over the top of the protector and thence into the drain opening. This is a safety feature which is of particular advantage.
Still another feature of the invention is the fact that it may be readily installed on conventional drains without the use of special tools and equipment.
A still further feature of the invention is the fact that it is simple in construction and of low cost of manufac ture.
A further feature of the invention is the provision of auxiliary means where the accumulation of leaves is particularly severe which may be installed seasonallyi.e., when leaves are falling-to surround the protector heretofore described and act as an additional means for screening out the leaves.
A still further feature of the invention is the provision of screening over the top of the auxiliary protector which prevents leaves from falling into the protector from direct- 1y overhead as would be the case if a tree were growing above the drain opening.
Other objects of the present invention will become apparent upon reading the following specification, and referring to the accompanying drawings in which similar characters of reference represent corresponding parts in each of the several views.
In the drawings:
FIG. 1 is a top plan showing the primary device installed as a protector replacing a conventional cover plate for a storm drain.
FIG. 2 is a vertical sectional view taken substantially along the line 2-2 of FIG. '1.
FIG. 3 is a view similar to FIG. 2, showing the auxiliary ring around the primary protector and also showing the protector on top of a conventional cover plate for said storm drain.
FIG. 4 is a fragmentary sectional view taken substantially along line 44 of FIG. 3.
3,121,582 Patented Feb. 18, 1964 FIG. 5 is a sectional view taken substantially along line 5-5 of FIG. 3.
At the present, a conventional storm drain 11 may be a vertically disposed pipe or other conduit leading to a storm sewer or other drainage accumulator. Such a drain 11 is, in accordance with the present invention, installed in a walk-way 12, or flooring, roof or the like. Set into the concrete walk-way 12, above the drain 1-1, is a frame 13, preferably rectangular in shape. It will be understood that with suitable modification the present invention may be used in conjunction with frames of different shape. A ledge 14 is cut around the inner edge of the frame 13. Used in conjunction with frame 13 is a cover plate 16 (see FIG. 3), rectangular in shape and having dimensions to fit inside the ledge 14. A plurality of holes 17 is formed in the plate 16, there being 16 such holes as shown in the accompanying drawing and the number being subject to considerable modification. Formed in one side of the frame 13 is a pair of recesses 18, in the inner periphery of frame 13, which receive ears 19 of the plate 16. The cars fit into the recesses in such manner as to hold the plate in position. On the side opposite the cars 19 is a lug 21 fitting in notch 15 in frame 113. Lug 21 receives screw 22 tapped into hole 23 in frame 13. The protector of the present invention is used to replace the cover plate 16 as in FIG. 2. However, it may also be installed directly over plate 16 as in FIG. 3 and held in place by the same means as the plate. For simplicity of description, the latter usage will be hereinafter described in detail.
The present invention provides a protector 20 to prevent clogging of drain 11. For such purpose there is provided a bottom 26, having the general shape of the plate 16 and formed with holes 27. When used on top of plate 16, holes 27 must match holes 17. Around the sides of the bottom 26 vertical upstanding side members 28, having scallops 29 along the top edge, it being observed that the top edge is of an elevation such that in emergencies water may overflow the sides 28 and directly down into the drain. If desired, sides 28 may be made removable. Sides 28 are formed with vertical slits 31, so that the portions bet-ween slits 31 comprise fingers 32 which act to strain out leaves but to permit water to flow normally through the slits 31 and thence through holes 27 and 17 into the drain 11. The fingers 32 are preferably crimped or angular in plan and twisted slightly out of vertical position to accommodate a greater :quantity of waterv Projecting horizontally out from base 26 is an ear 36 corresponding in position to lug 21 and fitting in notch 15 and from the opposite edge ears 37 fit inside recesses 18.
Where the problem of leaves is particularly serious, an auxiliary device may be used and preferably used temporarily during the fall when the accumulation of leaves is unusually severe. Such an auxiliary protector is a ring 41 surrounding the protector heretofore described likewise formed of sheet metal and having slits 42 extending up from the bottom. To give the ring 41 rigidity, the shape is preferably crimped in top plan as best shown in FIG. 4, in that the various sides of the ring are formed in small panels 43 at angles to each other. The slits 42 extend up about one-half of the height of the ring 41. To prevent leaves from falling directly inside the ring 41, screening 46 may be placed over the top of the ring 41, a short down turned skirt 47 integral with top 46 being fastened to the ring 41.
Thus the present invention provides an auxiliary as well as a primary protector to prevent clogging the holes 17 of a storm drain cover 16. The primary protector is substituted for or attached directly to the plate 16 by the ewe means which hold the plate 16 in the frame 13. The protector has slits through which water may normally flow into the drain 11, but which block the passage of leaves and other debris which might clog the holes 17. On the other hand, in cases of emergencies the protector is short enough so that water may overflow. The auxiliary protector, which may be placed around the primary protector in season, is of greater diameter than the periphery of the primary protector and thus has a greater area for screening out leaves.
What is claimed is:
1. In a storm drain protector, a frame shaped to surround a drain opening formed with a ledge in its upper surface and a notch, a coverplate closing off said opening and fitting within said ledge and formed with a plurality of first holes for drainage, a pair of oppositely disposed lugs on said plate, at least one of said lugs apertured, one said lug fitting in said notch, a fiat sheet metal base having a shape substantially congruent to said plate and lying flat on top of said plate, said base formed with a plurality of second holes corresponding in number and position to said first holes, a pair of cars projecting oppositely from said base, one ear extending into said notch, a screw fitting through the other said ear and said apertured lug and threaded into said frame to retain said plate and base in position, a plurality of fingers integral with said base and bent upward substantially at right angles to said base around the entire perimeter of said base, said fingers separated by first slits extending down approximately to the level of said base to permit ingress of water to said first and second holes, said first slits being relatively narrow to screen out leaves and debris, said fingers :being bent angular in transverse cross-section and flaring slightly outward at the top, a ring of substantially larger periphery than said base surrounding said base and plate and formed with a plurality of second slits extending up from its bottom edge to permit flow of water t through said ring and thence to said first slots, and screening over the top of said ring.
