The invention relates to water closets and
more ‘particularly to the construction and manu
facture of Water closets from pressed metal parts,
that is parts drawn, stamped, pressed or formed
from sheet or plate metal which may he stain
less steel, Monel metal or other corrosion resist- `
ing metal, or the pressed metal parts may be
coated with a vitreous enamel such as porcelain.V
Water closets for use in homes, hotels, oiîi‘lce
buildings and the like are of two general types,
,2.
A further object of the invention is to provide j
i'or the simpliñed manufacture `oi.’ a water closet
entirely of sheet metal 'stampings comprising a
bowl, a wash-out connection or goose neck siphon
tube, a jet tube, a perforated spray ring.. a header,
’a base and suitable support and trim members
which are welded and soldered together.
Another' object is to provide a-'method of mak
ing a pressed metal Water closet in which simple
the wash-out jet type and the Siphon iet type,
component stampings are so formed and 'as- Í
sembled as to hold and maintain their assembled
both of which are commonly formed of china.
positions and provide leak-proof joints therebe
` Although the type of Water closets used in rail
road cars and ' similar places have been made
largely of metal, and in some cases partly or en~
tirely of sheet metal, it is not known that water
closets of the washout or Siphon jet type, suitable ’
for use in homes and the like have ever been
made of pressedmetal. -
The production of pressed metal water closets
reduces the Weight of such plumbing fixtures and
also reduces the cost oi' manufacture and the cost '
tween.
Y
'
It is a still further object of the invention to
provide an improved and simplified design of
sheet metal water closet construction.
1
And a final object is the provision of an im
proved method of making- a pressed metal water v
