Description
Dec. 29,1931. J. c. CROMW ELL "R00? DRAIN Original Filed Aug. 19, 1924 INVENTOR P atented Dec. 29, 193i STATES JOHN C. CROMWELL, F ALLIANCE, OHIO, ASSIGNOR 'IO THE TESTI'IE COMPANY, OF
COLUMBUS, OHIO, A CORPORATION OF OHIO V ROOF DRAIN Original application filed August 19, 1924, Serial No. 732,893. Divided and this application filed 1929. Serial The present invention relates broadly to roof drains and has for one of its objects the provision of a drain of this character having a removable strainer detachably held in position and centered by the holding means.
Another object of the invention is to provide detachable clamping means for the roofing material, the clamping means being so constructed as to facilitate the drainage of water from the roof into the drain while preventing clogging thereof.
This application is a division of my copending application Serial No. 732,893, filed August 19, 1924.
In the accompanying drawings I have shown for purposes of illustration only a preferred embodiment of the present invention, it bein understood that the drawings do not define the limits of the invention, as changes may obviously be made in the construction without departing from the spirit of the invention or scope of my broader claims.
In the drawings,
Figure 1 is a top plan view of a portion of a roof having my improved drain in position therein; and
Figure 2 is a vertical sectional view through the structure illustrated in Figure 1.
In carrying out the present invention there may be provided a drainage cup 2 having its upper portion enlarged to provide a water receiving space 3 and having its lower end i contracted to cooperate with the upper end of the usual drainage or soil pipe.
Projecting outwardly from the upper edge ofthe enlarged chamber 3 is a horizontally extending flange 5 adapted to be embedded in the roof with its upper surface substantially fiush with the upper surface of the roof. This permits the roofing material or covering 6 to be laid smoothly both over the roof and over the flange 5. A portion of the body of the roofing material is preferably cut away to provide an opening slightly smaller than the diameter of the chamber 3, whereby there is provided a surplus of material adapted to project downwardly into the chamber 3. For tightly clamping the roofing material in position, there is preferably provided a detach- .Tuly 17, No. 328,940.
able clamping ring 7 having projecting therefrom a plurality of wedge shaped clamping projections 8 adapted to form therebetween drainage openings or recesses 9. Preferably the dimensions of the clamping ring will be such that with the parts in clamping position, as clearly shown in Figure 2, the upper edge of the ring 7 will project above the level of the roof. In this position the drainage of water into the cup 2 will be permitted by reason of the openings 9, while the passage of foreign bodies of undue size will be checked by the clamping ring.
Projecting upwardly from the inner portion of the cup 2 are diametrically opposed lugs 10 having inwardly extending webs 11 formed with openings 12. These webs are adapted to cooperate with and automatically center a strainer 13 of substantially dome shape adapted to project above the level of the roof and provided with a series of drain age openings 14. The base flange 15 of the strainer is preferably provided with diametrically opposite slots 16 and adapted to straddle the webs 11. vVith the parts in assembled position locking pins or keys 1'? may be passed through the openings 12 to prevent accidental removal of the strainer. At the same time, it will be apparent easy removal of the strainer is permitted by simply withdrawing the locking means 17.
The advantages of the present invention arise from the provision of a roof drain adapted to be easily positioned at any desirable point in a roof and having improved means for both clamping the roofing material in position and controlling the passage of water to the interior of the drain, while preventing the passage of foreign material thereto.
Further advantages arise from the provision of improved means for detachably receiving and centering the strainer.
I claim:
1. In a roof drain, a drainage cup, and a clamping ringcooperating with the cup, the ing having spaced projections portions of which form its clamping surface.
2. In a roof drain, a drainage cup adapted to be embedded in a roof and formed with a lower portion for cooperation with a drain pipe, and a detachable clamping ring for clamping the roofing material against the cup, said ring having a plurality of periph eral openings.
3. In a roof drain, a drainage cup adapted to be embedded in a roof and having a lower portion for cooperation with a drain pipe,
and a detachable clamping ring for clamping the roofing material against the cup, the periphery of said ring being formed by a plurality of alternate projections and depressions.
'4. In a roof drain, a'drainage' cup adapted to be embedded in a roof and having a lower portion for cooperation with a drain pipe, and a detachable clamping ring for clamping the roofing material against the cup, the periphery of said ring being formed by a plurality of alternate wedge shaped projections and depressions.
5. In a roof drain, a drainage cup, and a detachable clamping ring cooperating with said cnp, said clamping ring comprising an annular body having spaced wedge shaped projections thereon. Y
6. In a roof drain, a drainage cup adapted to be embedded in a roof and having a lower portion for cooperation with a drain pipe, anda detachable clamping ring for clamping the roofing material against the cup, said ring being adapted to project above the roof level, While permitting the drainage of water from the roof below its upper edge.
In testimony whereof I have hereunto set my hand.
JOHN G. CROMWELL.
