Specification of Letters Patent.
Patented Aug. 18, 1908.
Application filed September 14, 1906. Serial No. 334,602.
T all whom it mayconcern:
Be it known that I, CHARLES PFAU, a citizen of the United States, residing at Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Processes of Fitting Linings for ater-Closet Tanks, of which the following is a specification.
My invention relates to improvements in the process of fitting metal linings for use in flushing tanks for water closets.
The object of my invention is to provide a lining of improved construction whereby it is adapted to readily and properly fit into a tank casing in which it is intended to be used, which construction is hereinafter designated fitting.
My invention consists in the process herein set forth and claimed.
In the drawings which serve to illustrate my invention: Figure 1 is a sectional perspective view of a flushing tank provided with my improved lining, showing my preferred form of flange. Fig. 2 is a longitudinal horizontal section of a flushing tank provided with my improved lining. Fig. 3is a transverse section showing one end of the lining in elevation. Fig. 4 is a transverse section of a tank showing a modification in which the end of the lining is formed into panels. Figs. 5, 6, 7 and 8 are perspective views of modified forms of flange.
The method of constructing or fitting my improved metal linings for tanks is preferably substantially as follows: A sheet of ductile material, such as copper, is shaped up or bent into rectangular or other suitable shape to form the sides 1 and ends 2 and the meeting edges are seamed together, preferably by double seaming. A sheet of similar material is seamed to one edge of the sides 1 and ends 2 to form the bottom 3. The seams thus formed are then soldered to form watertight joints 4. The soldering of the joints causes the metal where soldered to expand so that the sides, ends, and bottom become distorted or warped, buckled and bulged out of shape. The linings are also formed in distorted sha e when made from a single piece or sheet of metal, due either to forming into shape or to irregularities in the sheet before being formed. In order to give said lining an even and regular form and adapt it to set firmly and fit properly in the wood casing 5 in which it is adapted to be used, I preferably emboss the bottom and sides by stamping them outwardly into regular form as panels 6 thus taking up the surplus metal developed in the initial treatment, substantially as shown in the drawing thereby removing any distortion and righting and truing the lining. The embossed portions are'thereby rendered perfectly flat and given a regular and finished appearance so that the bot tom of the lining will rest firmly upon the tank casing and the sides and ends of the lining will fit snugly against the sides and ends of the tank casing. There is also formed at each corner along the sides and ends between the lining and tank casing ventilating ducts 7 to take up the moisture or dampness, thereby preventing the wood casing from becoming water-soaked and moldy and preventing it from decaying.
When the lining is formed as above described or when it is formed of true material in regular and proper shape and form with out being distorted either before or after it is constructed into the lining, I provide the top edge of said lining with a resilient flange 8 consisting preferably of an inwardly extending corrugation 9 and an outwardly flaring lip 10 adapted to bear against the upper edge of the tank casing 5 to provide for a snug fit and to hold the lining in fixed and firm relation to the casing at the to Suitable vents 11 are preferably provide at the corners to communicate with ventilating ducts 7.
By constructing the upper edge of the lining with a resilient flange upon the upper edge normally exerting ressure outwardly notonly insures a snug t of the casing and lining at the top but also secures the lining in fixed relation to the casing without the use of extraneous fastenings such as nails or screws.
It will be apparent that my invention is capable of considerable modification without material departure from the scope and spirit thereof, as for instance, the flange may be formed as shown in Fig. 1 or as shown in Figs. 5 to 8 inclusive, if so desired, and for this reason I do not wish to be understood as limiting myself to the precise construction as herein set forth, but 1 What I claim and desire to secure by Letters Patent is:
1. The process of fitting metallic linings for angular shaped tanks which consists in shaping up a lining and subsequently taking up the surplus metal developed in the initial treatment by embossing the material of said lining, thereby removing; any distortion and righting and truing the lining.
2. The process of fitting metallic linings veloped in the initial treatment by embossing the material of said lining, thereby removing any distortion and righting and truj ing the lining.
"3; The process of fitting metallic linings for angular shaped tanks which consists in shaping up a lining having joints, then sol 15 dering said joints and subsequently taking up the surplus metal developed in the initial treatment by embossing the material of said lining, thereby removing any distortion and righting and truing the lining.
