I all whom it may concern.-

Be it known that I, CHARLES A. I\IILLER, a citizen of the United States, residing at Sturgis, in the county of St. Joseph and State of Michigan, have invented certain new and useful Improvements in Tanks for Water- Closets, of which the following is a specification.

This invention relates to improvements for flushing tanks for water-closets.

Flushing-tanks for water-closets as ordinarily constructed soon become checked or warped or the joints become loosened and pull apart.

It is the main object of this invention to provide an improved flushing-tank for water-closets which is not liable to become so injured or damaged, which is simple and economical in structure.

Further objects and objects relating to structural details will definitely appear from the detailed description to follow.

I accomplish the objects of my invention by the devices and means described in the following specification.

The invention is clearly defined and pointed out in the claims.

A structure embodying the features of my invention is clearly illustrated in the accompanying drawings, forming a part of this specification, in which Figure 1 is a perspective view of my improved flushing-tank for water-closets. Fig. 2 is a detail transverse sectional view therethrough. Fig. 3 is a detail vertical sectional view taken on a line corresponding to line 3 3 of Fig. 2 looking in the direction of the little arrows at the ends of the section-lines.

In the drawings similar letters of reference refer to similar parts throughout the several views.

Referring to the drawings, I provide a reservoir-boX which is made up of the end walls A and the side or front and rear walls B B, respectively. These walls are suitably secured together, and the front and end walls are secured to the bottom D. The rear wall B is left out of contact with the bottom D, leaving a narrow slit or opening b under the same.

l/Vithin the reservoir-box I place a suitable metal water-reservoir It. I provide an outer casing C for the reservoir-box. This casing is preferably made of a single piece of veneer, which is bent into suitable shape to inclose the front and end walls of the reservoir-box,

leaving an air-space between them and the casing. The-bottom D projects beyond the walls of the reservoir-box, and the casingwall C rests thereon, so that it forms a bottom therefor. Angle-shaped strips 0 are sccured to the rear ends of the casing-Wall and are lapped upon the rear ends of the end walls A of the reservoiebox. (See Fig. 2.) The tops of the reservoir-box and of the easing therefor are made flush, so that the cover D serves as a cover forboth. Thus arranged I secure an inclosed air-space about the ends and front of the reservoir-box. The reservoir-boX is provided with a pair of upwardlyprojecting dowel-pins d, adapted to engage suitable holes in the cover D to guide it into place and retain it in position. The bottom D and the cover D project at the rear flush with the angle-strips 0, so that when the structure is in position on the wall an inclosed air-space is formed between the wall and the "reservoir-box. The walls of the reservoir-box are thus entirely surrounded by air-chambers. WVith the parts thus arranged the contraction or expansion of the reservoir-box does not affect the outer casing, which may be ornamented or finished as desired without liability of its becoming injured. The air-chambers about the walls of the reservoir-box prevent the collection of moisture thereon and the consequent shrinking and swelling, thereby loosening the joints. It also does away with the necessity for accurately fitting the parts together, as if, as ordinarily constructed, a metal waterreservoir is not a close fit within the box so as to prevent the circulation of air the Water-reservoir will sweat, collecting a large amount of moisture. Should, however, the reservoir-box check or warp from any cause, the appearance of the structure is not affected, as the outer casing is thoroughly protected.

My improved flushing-tank for waterclosets is very economical to produce, as a great degree of skill is not required in making the reservoir-box and the casing C is easily conformed and put into place.

It is evident from the foregoing that as the parts of my improved flushing-tank are so well protected the same is very durable.

, I have illustrated and described my improved flushing-tank for water-closets in detail in the form preferred by me on account of its structural simplicity and economy. I am, however, aware that it is capable of con- IIO siderable variation in structural details without departing from my invention.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a tank for water-closets, the combination of a reservoir-box having a projecting bottom and an opening beneath its rear wall; a suitable water-reservoir; a casing for said reservoir-box, consisting of a single pieceof veneer conformed to inclose the front and j end walls thereof, resting on said projecting bottom; angle-shaped strips engaging the j rear ends of said casing and lapped upon the rear wall of said reservoir-box; upwardlyj projecting dowel-pins on said reservoir-box; and a cover common to both said reservoirboX and said casing, having suitable holes therein adapted to be engaged by said dowelpins whereby it is guided into and retained in position, whereby the walls of said reservoir box are surrounded by air-chambers, for the purpose specified.

2. In a tank for water-closets, the combination of a reservoir-box having a projecting bottom; a suitable water-reservoir; a casing for said reservoinbox, consisting of a single piece of veneer conformed to inclose the front and end walls thereof, resting on said projecting bottom; angle-shaped strips en aging the rear ends of said casing and lapped upon the rear wall of said reservoir-box; upwardlyprojecting dowel-pins on said reservoirboX; and a cover common to both said reservoirbox and said casing, having suitable holes therein adapted to be engaged by said dowelpins whereby it is guided into and retained in position, whereby the walls of sa d reservoir. boX are surrounded by air-chambers, for the purpose specified. v

3. In a tank for water-closets, the combination of a reservoir-box having a projecting bottom and an opening beneath its rear wall; a suitable waterreservoir; a casing for said reservoir-box, consisting of a single piece of veneer conformed to inclose the front and end walls thereof, resting on said projecting bottom; angle-shaped strips engaging the rear ends of said casing and lapped upon the rear wall of said reservoir-box; and a cover common to both said reservoir-box and said casin whereby the walls of said reservoir- 1 box are surrounded by air-chambers, for the purpose specified.

4. In a tank for water-closets, the combination of a reservoir-box having a projecting bottom; a suitable water-reservoir; a casing for said reservoir-box, consisting of asingle piece of veneer conformed to inclose the front and end walls thereof, resting on said projecting bottom; angle-shaped strips engaging the rear ends of said casing and lapped upon the rear Wall of said reservoir-box; and a cover common to both said reservoir-box and said casing, whereby the walls of said reservoirbox are surrounded by air-chambers, for the purpose specified.

5. In a tank for water-closets, the combination of a reservoir-box having a projecting bottom; a suitable water-reservoir; a casing for said reservoir-box inclosing the front and end walls thereof, resting on said bottom; upwardly-projeting dowel-pins on said reservoir-box; and a cover common to both said reservoir-box and said casing, having suitable holes therein adapted to be engaged by said dowel-pins whereby it is guided into and retained in position, whereby the walls of said reservoir-box are surrounded by airchambers, for the purpose specified.

6. In a tank for water-closets, the combination of a reservoir-box having a projecting bottom; a suitable water-reservoir; a casing vfor said reservoir-box inclosing the front and end walls thereof, resting on said bottom; and a cover common to both said reservoir box and said casing whereby the walls of said reservoir-box are surrounded by air-chambers, for the purpose specified.

7. In a tanl for water-closets, the combination of a reservoir-box; a suitable waterreservoir; a casing for said reservoir-box forming air-chambers about the walls thereof, said reservoirboX and said casing having a bottom and top common to both, for the purpose specified.

In witness whereof I have hereunto set my hand and seal in the presence of two witnesses.
