WATER LEVEL CONTROL ROOF DRAIN John Heinkel, St. Louis, Mo., assignor to John C. Kupferle Foundry Company, St. Louis, Mo., a corporation of Missouri Application May 31, 1940, Serial No. 337,956
Claims.
This invention relates to certain new and useful improvements in a water level control roof drain and pertains more particularly to that class of roof drains used for maintaining a water layer on flat roofs at a pre-determined level or depth for reasons either for eliminating fire hazard, for the preservation of a composition roof, or for cooling purposes of a structure housed byv the water covered roof.
One of the. objects of the invention is the provision of improved means in the drain for adjustably controlling the water level on a roof.
Another object is in providing the roof drain with self-containing water level controlling means which can be inactively disposed in the drain.
A further object is in the provision of means in a roof water drain to form an improved sump which is free from interference with the water level control means.
Still another object is to provide a regulating roof drain of an improved arrangement of parts which go to the efficient and operating capacity of the drain.
Another object is to provide a roof drain of a construction having improved means for its cooperable assembly in a roof.
With the foregoing and other objects in view which will appear as the description proceeds, my invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes may be made within the scope of what is claimed without departing from the spirit of the invention.
An embodiment of the invention is illustrated in the accompanying drawing, wherein:
Figure 1 is a vertical sectional elevation taken through this improved water level control roof drain.
Figure 2 is a horizontal sectional elevation of the structure shown in Fig. 1, but with a fragmentary portion thereof broken away.
Referring by numerals to the drawing, this improved roof drain comprises a bowl or sump 3 having a centrally disposed boss 4 with a vertical drain passageway 5 which is threaded as designated at 6, at its lower end, and engaged in said threads is the upper end of a drain pipe I.
'The drain opening 5 at its upper end is interiorly threaded at 8 and engaged in said threads is an interiorly threaded bushing 9, and seated in the interior threads of said bushing is a vertically extending regulating discharge tube In source (not shown) which is interiorly threaded its entire length, as
designated at II. The tube I 0 at its upper end is provided with wrench engaging means I2 for adjusting the tubeto extend to desired predetermined heights with respect to the bushing 9.
The bowl 3 is provided on its upper end with an annular horizontally disposed flange 12 for seating engagement on the boarding [3 of a roof when the bowl is positioned in an opening {4 which may be provided in the roof. 7
Fixed to the bowl '3 by vertically extending studs I5 and cooperating nuts I6 is a follower member 11 having an annular beveledportion 18 for cooperation with the beveled portion l9 of the bowl 3 to secure the marginal portion 20 of the roofing felt or composition 2|, therebetween. The follower member I! is provided with an annular vertical wall 22 having spaced V-shaped notches 23 therein and having their bottoms in approximately flush alinement with the roofing felt 2|.
The inner end of the boss 4 inside of the bowl 3 is provided with a horizontal seat 24 and mounted thereon is a gasket 25, and in engagement with the gasket is a flange 26 of a combined strainer and guard 21 which is disposed over the adjustable tube [0. The flange 26 of the combined strainer and guard 21 is provided with a recess 28 which is for cooperation with a projection 29 within the bowl 3 for securing the flanged end of the'guard 2'! in engagement with the gasket 25.
When this improved water level control roof drain is secured in a roof in the manner shown and described, and the tube [0 has been adjusted in the bushing 9 to a required height for maintaining a water level as indicated by the horizontal line 30 in Fig. 1, the water on the roof will be maintained at this level from a water supply Any excess of water will obviously flow over the top or upper end of the tube I0 and through said tube and into the drain pipe I, and the guard 21 having the vertical elongated openings 3|, will prevent floating substance such as leaves and the like, from entering the tube 10.
During the winter months or when it is desirable to drain the water from the roof, the tube In may be entirely removed from the bushings 9 by a tool being engaged with the wrench engaging means Ila at the upper end of the tube, or the tube may be manipulated to be lowered within the drain pipe I with its upper end flush with the top surface of the bushing 9, for safe keeping through the winter months.
Obviously, removal of the tube In from the bushing 9 or the disposing of the tube in the drain pipe I with its upper end flush with the bushing 9, will afford draining of the water from the roof, The vertical wall 22 having the notches 23 therein, during draining of the water from the roof, will prevent granular substances such as sand, from being drained into the bowl 3.
With the tube In being adjustably mounted in the bushing 9, it is quite clear that any desired water depth on a roof may be maintained, or at least a water depth consistent with the height of adjustment afforded by the length of the tube. Having thus described the invention so that those skilled in the art will be able to practice the same, what I desire to secure by Letters Patent is defined in what is claimed, it being understood that various changes in the device shown and described in detail and not amounting to invention, may be made without departing from the spirit and scope of my invention.
What I claim is: V 1. In combination, a bowl having a drain opening at its lower end, a drain pipe'in communication with said opening, a bushing 'in said open ing above the drain pipe, and a vertically extending tubular member adjustably secured in said bushing and adapted to be depended through said opening and into said pipe its entire length.
A Water level control roof drain comprising a bowl having a drain opening at its lower end, and 'a vertically disposed tubular member cooperably seated in said opening and adjust able up and down therein to positions either above the roof level or at the level of the drain opening, and said tubular member having wrench engaging means at one end and providing the sole means of draining cooperation with said 3. A roof drain comprising a bowl having a drain opening at its lower end, and a vertically adjustable tubular member cooperably seated in said opening and adapted to be depended in said opening its entire length, and said tubular member providing the sole draining means from said I bowl.
4. A roof drain comprising a bowl having an integrally threaded drain opening at its lower end, and a vertically extending exteriorly thread-
