DRAIN COVER.
Application filed September This invention relates to drain covers and more particularly to covers of this character adapted to be used in a street adjacent the curb as a sewer drain cover.
One object of the invention is the provision of a drain cover having av series of ribs arranged in a novel manner so that the tendency for the cover to clog is lessened or prevented. a J i A further object of the invention is the provision of a drain cover of the character mentioned in whichthe spacesbetween adj acent ribs decrease outwardly away from the curb in a gradual manner, he ribs extending at a slight angle inwardly toward the curb and forwardly in the direction of travel of drain water so that leaves and trash are washed by the drain water toward the curb line where the openings are larger and there is thus a lessened tendency for the drain cover to clog.
Other objects and advantages of the invention will be apparent from the description and from the drawings.
In the drawings,
Fig. 1 is a plan view of the drain cover of the present invention showing it mounted 111 place adjacent a curb of a street;
Fig. 2 is a section on the line 22 of F 1g. 1; and 1 Fig. 3 is an end view of the drain cover.
Referring more particularly to the drawings by reference numerals, the drain cover indicated generally by the numeral 10, as shown, is of rectangular form and 1s preferably constructed as a single metal casting formed of cast iron or other suitable material. It is adapted to be used adjacent a curb 11 of the street 12, the arrow (4 indicating the direction of travel of drain water down the street along the curb.
The curb 11 is shown having a side face 15 which may be of metallic construction this face resting upon a lower metal plate 16 and providing an opening through which drain water may pass to the drain. The end of the plate 16' forms an abutment against which the inner side of the drain cover 10 is placed. The street side of the drain cover may rest upon an angle-iron 20, the top of which merges with the street surface, indicated at 21 in Fig. 2. Additional side framing irons such as the angle-irons and 23 complete the bed in which the gratmg rests. It will be understood that any other suitable 6, 1927. Serial No. 217,757.
frame or bed maybe provided in the street of the street. The ribs or bars 24 extend ata slight angle inwardly towards the curb and forwardly in the direction of travel of the drain water and, as shown, are preferably curved gradually in form. These ribs are spaced a suitable distance apart and the space between adjacent ribs decreases outwardly away from the curb and towards the center of the street. The ribs themselves have a width which increases outwardly away from the curb, the change in the width of the ribs and the spacing between the ribs being gradual. As a result of this construction the flow of water in the direction of the arrow at along the curb and in the direction of the arrow 6 along the street will cause leaves and other trash carried along by the drain water to be washed toward the curb line, the direction of motion of the water flowing along the gutter being gradually changed by the gradual curve of the ribs. The leaves and trash will thus be washed towards the inner side of the drain cover where the openings between the ribs or bars are larger and the leaves and trash will thus fall in these larger openings between the. ribs and the drain cover will be maintained substantially free from obstruction.
The top sides of the various ribs 24: all
lie in a substantially horizontal plane flush with the street level 21 so that the flow of trash and water down the street and over the top of the drain cover towards the curb is easily permitted. As shown in Fig. 2 the curb side of thegrating is considerably greater in vertical height than at the outer or street side of the cover, the angledron bed on which the cover rests being correspond ingly placed in the street to receive the grating so that its top surfaceis flush with the street. The inner ends of the ribs or bars 24:, adjacent the curb, although of considerably less width horizontally than the width of the bars at the outer side of the grating, have considerably greater vertical height at this inner portion of the grating to provide sufficient strength to support passing vehicles or other loads which may be imposed upon the gratin. The grating is therefore sutliciently strong at all parts thereof to adequately provide for the support of heavy loads, without any portion of the grating being excessively heavy in its construction.
While the form of apparatus herein de scribed constitutes a preferred embodiment of the invention, it is to be understood that the invention is not limited to this precise form of apparatus, and that changes may be made therein without departing from the scope of the invention which is defined in the appended claims.
What is claimed is: v
1. A street-drain cover of the class de scribed connarisingr a grating having a series of spaced ribs, the upper surfaces of which lie substantially in horizontal plane flush with the street level, the'ribs being slightly curved inwardly toward the curb and forwardly in the direction oi travel oi? drain water, said ribs having spaces therebetween which decrease in size outwardly away from the curb. k
2. A street-drain cover of the class described eomprising a grating adapted to be used adjacent the curb of the street and having a series of spaced ribs, the upper surfaces of which lie substantially in a common plane, said ribs extending at a slight angle inwardly toward the curb and forwardly in the direction of travel oil. drain water, the ribs increasing in width outwarllly zirvzrr from the curb and having spaces thcrebetween which decrease in size outwardly away from the curb, so that leaves and trash are washed toward the curb line where the openings are larger to thus prevent clogging of the cover.
3. A street-drain cover of the class described adapted to be used :idjacent a curb of a street comprisin; a rectangular castiron grating having; a series: olf spaced ribs, the tops of which are substantially lush with the street and lie in a substz'ultiall horizontal plane, a perlpl'ieral frame with which the ends oi the ribs are integrally tori'ned, said ribs extending at a slight angle inwardly toward the curb and 'lorwardly in the direction of travel of drain water down the street, the ribs having spaces thercbetween which gradually decrease in size outwardly away 'lroni the curb, the vertical height of the ribs being substantially greater at the curb side of the grating than at the opposite side thereot'.
In testimony whereot I hereto allix my signature.
