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 closet which is light in Weight, inexpensive to manufacture, pleasing and attractive in appear ance, rigid in construction, made of corrosion re sisting material such as stainless steel or Monel of installation thereof, all oí which renders them metal without using excessive amounts of the available for low cost housing units. same, or made from hat steel enameledwith a In the manufacture of pressed metal water 25 vitreous enamel. closets there are a number of factors which must The above together with other objects and ad be considered, namely; uniformity in size of the water channel, a large water area at least egual to the seat opening to overcome soiling or the walls of the bowl, the jet chel or tube must _ vantages which will be apparent to those skilled in the art from the drawings and following de-. scription, may he attained by constructing the improved water closet in the manner hereinafter he drainable tcprevent ‘bursting when drained described in detail and illustrated in the accom for winter, a strong rim hush to thoroughly Wash panying drawings, in which the walls of the howl, provision to preventbach Figure l is a vertical, longitudinal section of siphoning, a minimum depth of Water seal, quiet a washout jet type Water closet embodying the and eñîicient operation, Water control and vac @d invention; uum brakes, an even-distribution or water in Fig. 2 a top plan view of the same with the seat flushing, and the jet should he concealed as the removed; l » jet opening cannot ‘oe readily cleaned and would show a dark spot in the bowl if not concealed. The manufacture of water closets from drawn, pressed or stamped» sheet metal parts therefor presents a problem which is made more dimcult vif the advantages of mass production methods are to be attained because if a minimum oi’ scrap Fig. 3 is a vertical, longitudinal section of a ' Siphon type water closet embodying the inven tion; Fig. i is a top plan view of the same with the ' seat removed; Figs. 5 to 8 inclusive are enlarged detail sec-= 1 tions of modiñed forms of rim constructions; loss is to result, each individual part must he as dit Fig. 9 is an expanded view _of the individual simple as possible in design and shape, and the parts used in making the spray ring and header assembly of the parts must he simple and ac sub-assembly; curate and the finished product must he leak ' Fig. 10 is a diagrammatic view showing the proof, uniform as to size and shape and attrac spray ring and header Sub-assembly formed from tive in appearance. , dit the parts shown in Fig. 9; It is therefore an object of the invention Fig. l1 is an expanded view showing the parts to provide a method of making a water closet used to make the bowl sub-assembly; made entirely or sheet metal stampings, which Fig. l2 is a diagrammatic View showing the conforms to the above requirements, overcomes bowl sub-assembly formed from the parts of the problems, mentioned, and realizes the ad to Fig. il; . vantages or mass production methods.
