FLUSILTANK FOR WATER-CLOSETS.

Specification of Letters Patent.`

Patented Jan. 19, 1909.

Application filed February 13, 1908. Serial No. 415,638.

To all whom it may concer/n:

Be it known that I, CLIFTON E. THOMP- soN, a ci izen of the United States of America, residing at I-Iolland, in the county of Ottawa and State of Michigan, have invented certain new and use Improvements in Flush-Tanks for Tater-Closets; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in flush tanks for water closets and its object is to provide the same with improved means for preventing corrosion of the metallic lining, and decay of the wooden case; to provide improved means for permitting the eX- pansion and eontractionbf the lining and to provide the same with various new and useful features as hereinafter more fully described and particularly pointed out in the claims.

My inventionl consists essentially of a wooden case provided with a sheet metal lining spaced apart therefrom, a corrugated member interposed between the lining and case and alternately contacting the same at its opposite sides whereby a series of vertical passages are provided between the case and lining, and fastenings at intervals inserted in respective vertical slots in the lining which is slidable over the fastenings, whereby the upper edge of the lining is movably supported relative to the case as will more fully appear by reference to the accompanying drawings, in which:

Figure 1. is a plan view of a device embodying my invention with the lining shown in horizontal section in the plane of the fastenings; Fig. 2. a transverse vertical section of the device on the line 2-e2 of Fig. 1.; and, Fig. 3. an inverted bottom plan of the device.

Like numbers refer to like parts in all of the figures.

1 represents the case of the usual form and preferably made of wood; 2 a sheet metal lining within the case and spaced apart therefrom at the sides and ends; 8 a lining adjacent to the inner surface of the wooden case and consisting preferably of paper saturated with parafn, rosin or other waterproofing material and 4t a vertically corrugated member contacting the lining 3 and the sheet metal lining 2 at alternate vertical lines, and preferably of like material to the lining 3. This member forms a substantial support for the sheet metal lining and also provides a series of alternating vertical ventilating ues.

7 represents openings in the bottom of the case and adjacent to the sides and ends thereof and beneath the corrugated member 4t, which is also spaced apart from the bottom leaving a channel all around between the lining 2 and the case 1 for the distribution of air entering the openings 7. Suitable fastenings 5 consisting of nails or screws having heads adapted to engage the inner surface of the sheet metal lining and slide thereon, extend through vertical slots 6 arranged at intervals near the upper edge of the sheet metal lining 2 and thence through the member 4 and lining 3 into the wooden oase.. The upper edge of the sheet metal lining is thus supported by these fastenings, about which the lining 2 moves as it eX- pands or contracts relative to the oase. T he lining 3 and corrugated member il effectually ventilate and carry away any moisture that may accumulate on the outside of the sheet metal lining 2 and prevent the same from reaching the case. The sheet metal lining is thus also protected from corrosion by any contact with the wood and moisture accumulating therebetween.

l/Vhat I claim is:

1. In a flush tank, a case having bottom openings near the vertical walls thereof, a sheet metal lining in the case spaced apart from the vertical walls, and a corrugated member forming vertical passages between the case and the sheet metal lining and spaced apart from the bottom to distribute air to the various passages.

2. A flush tank consisting of a case having Ventilating openings at the bottom, a sheet metal liningin the case and spaced apart therefrom, a` water-proof lining adjacent to the inner surface of the case, a corrugated member between the water-proof lining and the sheet metal lining and engaging the same at intervals at its respective sides, said member being also spaced apart from the bottom of the case.

In testimony whereof I affix my signature in presence of two witnesses.

CLIFTON E. THOMPSON.
