In a drain device of this nature there is a like

sitioned at an Vangle to the base Aplate, I2 and has
its lower end opening into the interior of the
pipe I8. At its upper end the conduit 32 includes

accordingly the 'purpose of my invention to pro
vide a roof drain with an auxiliary drain which
will function should the main drain become
45 clogged to lower the water level on the roof.
According to my invention I provide a main
drain and an auxiliary drain with a syphon com
bined with the auxiliary drain and this structure
is set forth in the accompanying drawings.

Referring to the drawings by reference charac
ters I have shown my invention as embodied in a
drain device which is indicated generally at I0.

From the foregoing description it will be ap
parent that I have invented a novel drain device
which can be economically manufactured and
which is highly eñìcient for its`intended purpose.
Having thus described my invention I claim:
When the »device I0 is installed on a roof the
well portion I4 is positioned between a pair of
adjacent rafters 35 and the base plate I2 over
lies one layer of roofing material 36 on the disk
3'I. Plastic material 38 is positioned between the
10 plate I2 and the roofing material 36. Plastic
material 39 is placed on the base plate-.I2 and
then a sheet of rooñng material 40 is laid over
the plate I2 upto the flange I1 and ñrmly
pressed in place. The plastic material 38 and
39 bonds together through the plate apertures
I2' thereby forming a water tight seal. `
