. Patented Sept. 4, 1906.

To all whom, it may concern:

Be it known that I, FRANK A. MAGOWAN, a

citizen of the United States, residing in Trenton, in the county of Mercer and State of New Jersey, have invented certain new and useful Improvements in Flush-Tanks, of which the following is a specification.

This invention relates to a specific form of flush-tanks which are made of ceramic or vitreous material and in which the tank is inclosed in a case so that a little space is left be tween them on nearly all sides, whereby the case is not in direct contact with the water in the tank, and hence the water cannot cool the case sufficiently to cause condensation or sweating upon the exterior of the latter.

The specific form of the invention herein claimed comprises a closed bottom case molded in one piece'with the contained tank and having a common rear wall, but separate bottoms, ends, and front walls, and joined at their rim portions, studs being formed between the tank and case and integral with both to make a strong structure and the case also being -ioined to the tank at their rims and provision being made whereby the case i takes the overflow, if any, from the tank.

The case in this form of the invention is provided with means whereby it may drain into the same flush-pipe that receives the water from the tank, said pipe opening into the case aswell as into the tank.V

In the accompanying drawings, Figure 1 is a sectional front elevationshowing the tank, case, and studs, all integral, with their appurtenances.l Fig. 2 is aV front elevation of the apparatus. Fig. 3 is a sectional side elevation thereof. Fig. 4 is a plan thereof on a smaller scale.

The tank may comprise rear and

front walls

1 and 2,

side wall

3 and 4, and bottom 5, forming a box and molded of clay or 'vitrified ware, preferably without glaze or finish. It is supplied'with water through a pipe 6,`hav ing the usual nozzle 7 and iioat 8 for regulating theflow. Thetank discharges through a flush-pipe 9, having at its top any usual or suitable apparatus for controlling the discharge-such, for instance, as a valve 10, whichmay be operated in any way, as by a link 11, a lever 12, and chain 13. The top of the pipe is shown inclosed in a packing-ring 14, which may be of rubber and is inclosed in a cup 15, formed below .the level of the tankfloor, and having top and bottom flanges 16 and 17, which confine the'packing 14, it bethe tank ing intended that said cup may contain the packing-ring when the tank is sold to dealers. The diameter of the hole in the bottom flange 17 may be greater than that of the pipe, so as to give clearance for the latter. The case, which is also formed of either ceramic or vitreous ware, comprises vsides 18 19, a front wall 20, and a floor or water-tight closed bottom 21, and, as will be seen, forms a vessel surrounding the tank on its sides and bottom and is larger than the tank, so that an air blanket or space 22 is left between the tank and the case on all sides except the back. -The rear wall 1 of the tank is extended at 23 to meet the sides of the case, thejlatter not having a separate rear wall. The rear wall is also shown as extended to form a vertical flange 25 on the sides and bottom of the case, throughwhich may pass bolts 26 for supporting the apparatus upon a wall.

In manufacture the tank is molded separatelyfrom the case, and they may be united, as by means of studs 32, which form supports between the tank and case not only during firing, but also during the subsequent life of the structure, serving to give a great degree of solidity to the same. The supply-pipe 6 passes through a stud, being packed by a ring 6E. lThese studs, it Awill be understood, are molded to or become integral with both the tank and the case, so that all form one piece of ware without break or joint.

In order to drain off the overflow and, as well, any` condensation from the outside of proper, I cause the Hoor 21 of the case to sop`e toward a cup or pocket 34, formed below the cup 15 and having a bottom opening 35, through which passes the flush-pipe 9. The latter is provided with weep holes or perforations 36 within the cup 34 and, as will be seen, comlnunicates with the case wholly independentl of its'communication with the tank. ithin the cup 34 is provided a packing-ring 37, which is inclosed between

flanges

38 and 39 in the manner a1- ready explained with referenceto the packing-ring 14, the perforations in said fiange's '38 and 39 being of preferably larger diameter than the pipe 9 to afford suitable clearance for the latter. The case is shown closed at its top and there united with the tank to give the appearance of a single-wall tank and to strengthen not only the rim, but the entire structure. This joint or union between the case and tank is indicated at 45, and below it are provided suitable holes 46 to carry off loe A the other.

an accidental overflow from the tank. It Wil be understood that the tank and vcase may be joined in this manner, even if one is made of a different grade of clay or ware from The case may be made of highgrade clay suitable for lazing, while the tank may be made of a mo ded substance not suitable for glazing, and still they may be united at their edges into an integral struc'- ture, or, if desired, both case and tank may be made of a lowade vitried ware, such as commonly pro uced in potteries, and a suitable glaze ut upon the case without glazing the tank),` the inside of the case and outside of the tank of course remaining unglazed. Hence the device, although having a highly-finished ap e'arance and excellent desi n, may be manu actured at trivial cost.

A though the joint or rim 45 forms a continuation of the brim of the tank, still it will be understood that there is no liability of sweating or condensation upon the case, be-

cause, owing to the distance of the uplper part of the case from the upper part oft e tank, the case may remain at the temperature of the room, whilethe tank is cooled a little by the water-that is to say, the case is too far away from the tank for the water to cool the former even thou h continuous with the tank. Moreover, t ere is a circulation of air in the 'space between the tank and the case. The overflow-openings 46 may be made very i frequent and extensive, so that there will be a 'minimum of convection of heat between the top of thetank and the top of the case.

Certain variations may be resorted to within the scope of this specific form of the invention and portions of the improvements herein claimed may be used Without others.

Having thus described Amy invention, I claim- .1. A closed-bottom case in combination with a flush-tank, both .of vitreous or ceramic ware, the tank within the case and slightly 'separated therefrom, and studs molded in one of said elements and extending to the other thereof. 2. A case and a flush-tank both of vitreous or ceramic ware, the tankl within the case but sli htly separated therefrom, and studs molde to both of said case and tank elements. Y

3. A case and a flush-tank both of vitreous or ceramic ware, the tank withinthe case but slightly separated therefrom, and studs of ceramic or vitreous ware between the tank and case and molded together therewith, so that the case, tank, and studs form an integral or single piece.

4. A Hush-tank and case slightly separated therefrom and molded together therewith, and studs extending from said tank to said case and integral with both thereof.

' 5. In combination, a flush-tank and a case in which it is contained and from which it is slightly separated so as to prevent the case from sweating, the tank and case molded toether of ceramic or vitreous Ware, and a ush-pipe opening into said tank; said case having a drain terminating at said pipe, and the latter having an opening into which the case may drain. g

6. A Hush-tank in combination with a case in which it is contained and from which it is slightly separated, and a Hush-pipe opening into said tank; said case having a pocket or cup at said pipe, and the latter provided with in which it is contained and from which it is Y 4slightly'separated, and a Hush-pipe opening into said tank; said case having a pocket or cup at said pipe, and the latter provided with an opening through which water collecting in said cup vmay discharge; and a packing or yielding material between said pipe and said casing.`

8. A flush-tank and case molded in one piece of vitreous or ceramic ware, and slightly separated, and joined at their rim portions; and studs between said case and tank and integral therewith.

9. A closed-bottom case, in combination with an inclosed tank, bothl molded in one pieceof vitreous or ceramic ware and having a common rear wall but separate bottoms,
