WATER-CLOSET TANK.

Specification of Letters Patent.

Patented Apr. 2, 1918.

7 To all whom it may concern:

.Beaver and State of Pennsylvania, have invented a new and useful Improvement in Water-Closet Tanks, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification, in which Figure 1 is a perspective view of a tank embodying my invention; and

Fig. 2 is a section on the line IIII of Fig. 1.

My invention has relation to water closet tanks, and is designed to provide a metal tank which can be readily manufactured by casting and which will be free from projecting flanges of a character likely to become broken. My invention also provides a tank in which the supporting means are concealed and which has an effective wall bearing.

Referring to the accompanying drawings, in which I have shown the preferred embodiment of my invention, the numeral 2 designates a cast metal tank which, in so far as its general shape is concerned, may be of any approved design. In accordance with my invention, the rear wall of the tank is cast with the centrally inset portion 3,

havin at its top the overhanging shelf 4,

from which depend the lugs 55, which are designed to engage the usual hangers which support the tank from a wall.

It will be noted that instead of the usual rearwardly projecting flanges at the rear corners of the tank between which the supporting hooks or lugs are formed, I provide the broad wall-bearing surfaces 6, and inset the rear wall to provide for said lugs, the surfaces 6 extending the full height of the tank. I-Ieretofore, it has been customary to casttanks of this character with avertical flange at each edge, and between which the attaching lugs have been placed. In order to give proper draft in molding, these flanges have been made of downwardly tapering form, thus giving unequal thickness of metal which is objectionable in the enameling operations. The flanges have also necessarily terminated short of the bottom of the tank, thus leaving unsightly openings between the tank and the wall at these points. Furthermore, such flanges frequently become broken in cleaning the castings and in subsequent handling, shipping and crating.

My present invention overcomes all these difliculties, provides a tank in which the metal can be of substantially uniform thickness throughout; which is neat in appearance; which is not likely to be broken in handling and use, and which can be readily manufactured. The broad wall-bearing surfaces 6 give the tank a firm wall bearing.

As above indicated, I do not desire to limit myself to any particular design of tank which I have herein shown and described, since the general shape may be widely varied without departing from the spirit and scope of my invention as defined in the appended claims.

I claim:

l. A closet tank having its rear wall formed with an inwardly extending inset portion, substantially as described.

2. A closet tank having its rear wall formed with an inwardly extending inset portion, and with a shelf overhanging said inset portion and provided with attaching means, substantially as described.

3. A closet tank having its rear wall formed with an inwardly extending inset portion, the portions of said wall at each side of the inset portion forming relatively broad wall-engaging surfaces, substantially as described.

In testimony whereof, I have hereunto set my hand.

JOHN M. SHAFFER.
