linings for tanks designed to hold liquids,

and it is especially designed for a lining to the wooden boxes which are used asflush tanks for closets. Its objectis to provide..

such a lining cheaper and more efiicient than those in common use. This object I accomplish by the construction shown inthe accompanying drawings, which is a cross-section of a tank and lining constructed in accordance with my invention.

In thedrawing the numeral 1 represents the ordinary wooden tank or box. v

The numerals 3 and 5 represent the sheets of fibrous material orsimilar substance, and the numerals 2 4 and 6 represent coatings of waterproofmaterial applied upon and be tween the sheets 3 and 5.

The numerals 7 7 represent suitable supports or stops held in their ex anded osition and pressing against the ining o the tank through the operation of theconnecting spring 8.

As a basis or body of my lining I use a fabric, preferably of very open texture, like burlaps, or any fibrousmaterial, as, for example, felt, even'if not woven into fabric, or

I may use a combination of felt and some a fabric; I then coat this base or body with a waterproof adhesive material}, like. pitch or asphalt. For the best results I prefer not only to coat the base with this material upon one or both sides, but also to saturate the base therewith, and I do this by dipping it into a tank of the asphalt, or similarsubstance in melted form, andwhile hot, thus securing both saturation and coating upon one or both sides; or the base may be saturated first and afterwardcoated with a waterproof material-by the use of a brush or mop, or in any other suitable manner.

. The sheet ofniaterial thus produced, while perfectly waterproof, could not be used for tank lining since it would not, ordinarily, be self-supporting, and could not be glued or firmly attached to the interior of the box without being affected by the shrinking and swelling of the latter; or if some material should be found for the base, which, thus treated, would be sufiiciently self-supporting, the waterproof coating would not retain its position, but, when heated, would flow, down to the bottom of the sheet; and in any event the sheet 'could not be handled on account of itssticky and adhesive character. To make it-extra self-supporting so that itwill retain the desired position, andso that, the

waterproof material will not flow in an unde- 6 5 sirable way and so that the sheet can be handled practicably, I unite with the pitch or asphalt, while hot, a proportion of a stiffening or tempering material in a finely pulverized condition. dered carbonate of lime, or marl, or other suitable powdered stone. This must be pulverized finely enough so the waterproof character of the composition will not be affected. Imix I use for this purpose powthis pulverized material with the asphalt, 5

or similar materiaL-whilethe latter is hot, and a complete mixture can easily be made; The material will thus. be tempered or stiffened in a varying degree, according to the temperature and conditions under which the complete article is expected to be used. This stiffening might be accomplished to a sufiicient degree by spreading the stiffening ma terial upon: the outer surface of the hot plas tic material on the lining; but I find it the 8 most efficient way first to unite this ow- .:.,d ered stone with the hotliquid aspha t in proper pro ortions and then to saturate and coatthefi rous material with the resulting composition. When this cools and sets, I 0

have a 'sheet'of material es eciallyadapted for my purpose, which is a solutely waterroof and which can be'bent without break mg, but which is stiff enough to be sufficiently self-supporting for the urpose for which it is 9 5 designe andalso" flexi 1e enough to be especially adapted for thisuse. The sheet of this material can be formed into the shape of the box which it is to line by any suitable forming or building up process, and such joints as result at the 'corners or elsewhere can be coveredwith a coating of thesame, or other suitable composition, thereby making them waterproof or water-tight.

This lining canbe used in one ply form and to 5 coated or saturated, or both, or it can be used in two or three ply forms. I have shown in the drawing a two ply form in which the oomplete lining has five la ers, two layers of felt or fibrous material, t e interposed layerof no terial is' em manently,

waterproof material, and the exterior layers of waterproof material, the one unitary, body.

If a greater proportion of the stiffening material is applied, the resulting lining will .be sufficiently-rigid to retain its position perand without any attachment to If a less'amount of stifiening maloyed, the lining may tend, un der a consi erable heat, to collapse. This result will not follow after the tank is in use the box.

and filled with water, as the temperature ofwater used for that purpose is low enough to keep the'composition firmly set; but, in order .to guard against collapse which might happen from'temporary heat in shipping or stor age, I may supply the interior of the .boxes with temporary supports, shown in the drawing by 7 7. These are protected from adhesion to the interior surface of the lining by interposed Waxed paper, or in any suitable way, and are held in contact with the interiorof the lining by the spring 8. These kee the lining 'in sha e during the shipping and storage, and w1 l be taken out and t whole forming ing for own away when the lining is put into use. Similar supports can be used for the opposite aeaeee side, or this temporary'support could be provided 'in'any suitable wa Having thus described my invention, what I claim to have invented, and desire to secure by Letters Patent,"is

1. As a newarticle of manufacture, a linflush tanks composed of two sheets of fibrous material, a layer of water-proof material having a stiffening means interposed between the two sheets, a layer of waterproofmaterial against the outer face of one of the sheets, and a layer of water-proof'material against the outer face 1 of the other sheet of material, said last-mentioned layers' embodying a stiffening medium. 7

2. As a new article of manufacture, a lining for flush tanks composed of a base of fabric coated with a water-proof material embodying 'a stiffening medium.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
