ROOF DRAIN.
Application filed October 18, 1923. Serial No.`669,275.
' T 0 all w/i-om t may concern.'
Be it known that I, ARTHUR HEss, a citizen of the United States, and resident of Los Angeles, in the county of Los Angelesand State of California, have invented new and useful Improvements in a Roof Drain, of which the following is a specification.
This invention relates to roof drains having a pan for the purpose of collecting and discharging into the drain any water that may leak around the drain head.
Frequent occasions arise for draining water from the surface of iioors, roofs, and the like by means of drain pipes which pass through the Hoor or roof. It is essential in such constructions to prevent water from the surface to be drained from leaking through and around the outer surface of the body of the drain and between it and the walls of the opening through the floor or roof made for the passage of the drain. To this end a pan has been provided on the drain body, it extending outwardly therefrom. This pan is for the purpose of collecting water which is discharged therefrom through seep holes into the drain head. In roof drains, the head comprises a cup sunk into the roof below the level of the surfaces to be drained and a strainer extending above the roof level and connected to the bottom of the cup. When the drainage system backs up for any frequent occurrence, the water will pass through the seep holes from the drain into the pan, and may pass over the edge thereof and through the ceiling, thus, causing damage. The primary object of this invention is to provide a drain of the character described with means to prevent water from backing 4,0 up into the pan.
These objects together with other, objects and corresponding accomplishments are obtained by means of the embodiment of my invention illustrated in the accompanying drawing, in which:
' Fig. 1 is a vertical section through a roof with my improved drain installed therein; Fig. 2 is a plan view; and Fig. 3 is an enlarged fragmentary view showing the pan check.
Referring more particularly to the drawing, the body comprises a cylindrical coupling portion 4. A cup or basin 5 projects upwardly beyond the coupling and khas a flange 6 intended to set ush with the sur- 'which the roof reason, which is not an iny face level Vof the roof. Extendingoutwardly from the cup is a pan 7 to receive water or liquid which may leak between the roof wall and the cup. The coupling 4 yis extended into the cup to receive a basin ring 8 which is provided with an internal shoulder so that it may be slipped over the end of the coupling portion. Secured to the base ring is a screen 9 protecting the drain pipe opening against the entrance of leaves, refuse and insoluble foreign material. The screen extends above the roof level so that in case sediment and foreign matter collect and lill the cup to the level of the roof, water may still flow into the drain pipe. The inside of thel flange 6 is arranged to form a bead over paper or composition roong 10 is folded. An expansible fastening ring 11 is disposed against the paper below the bead and is provided with ears 12 threaded to receive left and right hand threads on a threaded screw 13 provided for the purpose of expanding the ring.
At the bottom of the cup 5 adjacent its junction with the body 4 is an enlargement providing a chamber 14 opening into the pan 7 at the top and communicating at the bottom through a passage 15 with the cup. The upper portion of the chamber 14 is internally threaded, and mounted therein is a valve cage 16. The cage is in the nature of a plug having perforations 17 opening as ports into a valve seat. Fingers 18 embrace a ball check 19. This ball is formed so that it will float upon the liquid. Normally the ball rests upon the bottom` of the chamber 14, thereby keeping the port open.
In the normal operation of the device, any water which seeps or leaks along the outer wall of the body will enter the pan 7. From the pan it may pass through the ducts 17 into the chamber 14,`and into the cup 5. A safe waste is thus provided, and water will not leak to the ceiling below.
The roof may be of concrete, with the drain embedded therein as shown in Fig. 1. The position of the pan in the roof is immaterial. It may be threaded above the lower surface of the roof at the lower surface as shown in the drawing or below the lower surface. should become clogged, liquid will back up into the cup 5, Hoat check 19 will rise and close the port to opening 17- This prevents liquid fram Passing so that water or If the drainage system into the pan and illing the latter, then overflowing and damaging the portion below the roof.
" Ihat I claim is:
l. A roof drain comprising a body provided with a cup open at the top of the root7 a safe waste pan extending outwardly below the top thereof and having eoinniunication with the body to carry back liquids entering said pan, and a Check controlling said communication to prevent the passage of liquid from the body to said pan. p
2, A roof drain comprising a bodT av draining chamber open at the top of the roof, a safe Waste pan extending outwardlbv below the top thereof, there being al passage between said pan and said cup to carry back liquid enteringsaid pan, a cage detachably mounted at thev upper end of said passage and in said pan, and a 'float check ball mounted in said cage for controlling said passage to prevent liquid from entering` said pan from said cup.
In witness that I claim the foregoing I have hereunto subscribed my name this lst day of October, 1923.
ARTHUR HESS.
