Specification of Letters Eatent. :.1 Paiugntgff, Jamin it), 1922.

Application filed october 4, 1920. Serialo. 414,636.

To all whom t may concern:

Be it known that l, Hennen D. CARTER, a citizen of the United States, residing at Multnomah, in the county of Multnomah and State of Oregon, have invented a new and useful Improvement in Swimming Pools, of which the following is a specification, reference being had to the accompanyino1 drawings.

viy invention relates to devices as a class, wherein water is conned for instruction or pleasure purposes, commonly called swimming pools or tanks.

My object is to provide a device of this character wherein a tank or container is provided with mechanism to force streams of water upwardly from the bottom thereof to agitate and allow buoyancy of the water therein at its surface, also to allow a continuous changing of water in said tank. These objects, as well as other advantages, I attain by the construction, combination and arrangement of parts illustrated in the accompanying drawings which form a part hereof.

Fig. 1 is a side elevation of the device, partly in section on the line 1-1 in Fig. 2.

Fig. 2 is a plan view with parts of pipe connections omitted.

Like characters refer to like parts in the views.

ln the form illustrated, a primary water tight tank 3 is provided. Nithin said tank a secondary tank 4, of desired lesser dimensions and height is placed upon a series (if-supports 5. The tank l has spilling rims 6 about its upper edges and a discharge port 7 in the bottom. In one end of the tank 8, near its bottom, a 'iT-pipe 8 is placed. Its shorter arm extends without the tank, its longer arm transversely within the tank. A series of pipes 8L extend from the longer arm of the 'lpipe longitudinally within the tank 3 and below the tank ll, their opposing f ends being closed. A series of short branch pipes or jets 9 extend upwardly from the pipes S and through the bottom of the tank f1 into which the jets 9 open. Without the tank 3 the shorter arm of the T-pipe 8 `has a two-way valve 10. From this valve, one

pipe 11 extends to a desired outer source of v water supply and another pipe 12 extends to a pump 13. A feed pipe 14 extends from the pump to a two-way valve l5. From this valve one feed pipe 16 extends to a ,suitable outer source of water supply and another pipe 17 extends to a third ytwo-way valve 18. ll rom this valve one pipe 19 extends into the tank 3 near its bottomy and another pipe 2O extends to a suitable location for discharge of water.

It will now be seen that, by means oi' the pipe system illustrated, water from the primary tank 8 may be pumped therefrom and forced, through the pipe series Se and the jets therein, upwardly through the bod of water in the secondary tank C toward the surface of said water, which then falls over the spillway at the ends or sides into the primary tank, and is again pumped through the same circuit. ln this operation, the valve 10 is closed to the pipe 11 and opened to y the pipe 12, the second valve 15 is closed to the pipe 16 and opened to the pipe 1? and the third valve 18 is opened to the pipe 17 and closed to pipe' 20. lt is understood that in this operation the tanks are rst supplied with water in a desired quantity `to retain the secondary tank iilled and enough in the primary tank to insure the same-supply in the secondary tank as it is spilled over during the pumping. lt will further be seen that by a proper setting of the valves, water from an outside source may be pumped through the pipe 16, and, after passing through the tanks as described, discharged through the pipe 20. lt will again be apparent that by a diderent setting of the valves at each end, water under pressure from a desired source, such as the main of a water system, may be forced through the pipe 1l and the tanks in the same way and discharged through the pipe 20. rihe first method is intended for the use of the same water with which the tanks are first supplied, when it is necessary to economize in the water supply. ln this case filtering 'means may be installed at some convenient position inthe pipe circuit. rlfhe second method is for use where the supply of water is unlimited, for example, when. the tanks are placed in a stream or other large body of water. rlhe third method is adaptable to a water pressure system such as is common in cities. This latter method furnishes a most eHicient and rapid means of completely changing water in the tanks whenever desired, as well as scouring them.

It is well known that when water, in spouts or jets, is forced or discharged by any means, upwardly from the bottom and through a body of water, a buoyancy is cre ated at the surface thereof and objects thereabouts are caused to'float, when they would otherwise tend to sink more or less. Applying .this principle, my device and its operation enables swimmers, or those learning the art, to be kept near the surface, which is very advantageous to the learners particularly. By increasing the upward force of water through the jets, a miniature storm or rough water may be created to furnish pleasure to those who are practical swimmers. The device therefore combines facilities for both instruction and pleasure. In these re'- spects it is new and useful, as well `as economical and sanitary in operation. lhile I haveshown the series of pipes 8a below the bottom ofthe tank 4L, these pipes may be positioned within said tank alongw its bottom, and provided with jets to operate in the same manner, and the tank 3 omitted, :without departing fromrthe principle of my invention and constituting an equivalent thereof. rl`his would'allow the installation of my device in pools now constructed, at a minimum cost. In this latter arrangement of these pipes in a single tank, a spilling trough or other suit able means would be provided about the top of said tank, and the discharged water be drawn therefrom or discharged out of it in the same manner as contemplated in relation to the primary tank shown, and inrthis respect be likewise an equivalent of the method illustrated.

I claim- Y 1. A swimming pool, wherein is combined, a tank, a secondary tank of smaller dimensions supported within thev first tank free from the bottom and walls thereof, a pipe extending from a desired source of water supply into the first tank, a series of pipes extending within the first tank from the sup ply pipe below the secondary tank, and a series of jets extendingh vertically from said pipe Series t rough the bottom of the secondary tank, the jets having tight joints at each end, the whole being arranged to allow water from said source to be forced upwardly within the secondary tank to cause buo anc near the surface of the bod f of water therein and allow a spill to the primary tank. i

2. A swimming pool, wherein is combined, a tank, a secondary tank of smaller dimensions supported. within the rst tank free from the bottom and walls thereof, a pump,

la pipe extending from the pump within the Vfirst tank, a series of pipes extending from nonnen D. (Daarna.
