STATES crrics WATER TEMPERATURE CONTROLLING FOUNTAIN My invention is a water cooling and drinking fountain in which is maintained a constant po tential supply of water ready to be liberated at a drinking fountain proper, at the will of the user,

and pertains especial y to drinking fountains comprising temperature controlling water coil means through which the water supply for the drinking fountain proper is directed; and the invention consists substantially in the construc- 19 tion, combination and arrangement of elements hereinafter set forth and pointed out more particularly in the claims.

It is a primary object of this invention to provide an outdoor drinking fountain, the water of which is protected against freezing during winter Weather.

t is also a primary object of the invention to provide a drinking fountain having an underground temperature controlling coil through which the water travels to an overground drinking fountain.

It is an important object to provide a device of this class having means to give and close oif access to the fountain proper and fountain bowl as desired, and means to lock the device in closed off or open position as desired.

It is a further object to provide ventilating facilities throughout the underground and overground parts of the structure which function, both when the fountain bowl is. closed off and when opened.

t is a further object to provide sewer connections anda trap for draining the fountain bowl and means to direct. a flushing water stream through said connections and trap from the source of fountain water supply, independently of the drinking fountain proper and fountain bowl.

The above and other objects are attained by the structure illustrated in the accompanying drawing, in which: 1 7

fi ure 1 is a fragmentary side View of the invention in which the underground portion of the apparatus is illustrated sectionally, the fountain proper being shown, closed off from use;

Fig. 2 is a sectional side View of the overground portion of the apparatus, the fountain proper and the fountain bowl being shown as when closed off; and,

Fig. 3 is a plan View of the extreme upper portion of the apparatus, in open position.

Similar characters of reference designate similar elements throughout the different views. Referring to Fig. 1, the numeral 1 designates the 55 overground portion of the invention, and the the pin 24, and valve crank 23.

numeral 2, designates the dry well which consists of the lower dry well proper 3, and the upper or connection room 4.

The overground portion of the apparatus is illustrated sectionally in Fig. 2, in which the numeral 5 indicates the fountain body, the horizontal cross section of which is of substantially square formation as will be understood from Fig. 3.

Spaced slightly from the upper edge of the fountain body 5, the fountain bowl 6 is secured within said body. As best indicated in Fig. 3, said bowl is preferably a round basin like device, by which characteristics as will be subsequently understood, vacant spaces are provided between the edge of said bowl and the corner formations of said fountain body, said spaces serving as part of a self ventilating system for the invention as will be understood.

The fountain bowl 6, is provided conveniently at a medial point with a drain outlet pipe 7, and conventional trap 8, similar to an ordinary sink trap. Said trap communicates with underground drain piping 9, through a vertical conduit 10.

The drinking fountain 11 protrudes upwardly through the wall structure of the bowl 6, and serves to direct a stream of water somewhat horizontally into said bowl. Said nozzle is conveniently fedthrough a nipple 12, a valve 13, and

piping 14, from a temperature controlling coil 15, which is disposed in the lowermost portion of the dry well proper 3, said controlling coil being in turn fed with water under pressure from a water supply source through conduit 16.

The user obtains water through the nozzle 11, by opening the valve 13 by means of the lever 1'7, which in this example of the invention is readily operated by the foot. Said lever is fulcrumed to'and Within the lower portion of the fountain body 5, by a. fulcrum pin 18. Downward thrust of the exposed lever pedal 19 which is secured to the protruding end of said lever, forces the opposite. and inwardly disposed end 20, of said lever upwardly, the extreme inward termination of said lever being pivoted to the upwardly extending rod 21, which is guided through the stationary guide 22. The valve operating lever 23 in this particular form of the invention is provided with a longitudinal slot and a cross pin 24 is rigidly secured through the rod 21, and somewhat loosely disposed through said slot, by which arrangement it will be understood that upward shifting. of said rod by downward thrust of the pedal 19 will open the valve 13 through A weight 25,

is conveniently provided between the fulcrum pin 18, and lever end 20 to return the rod 21, and lever 1'7, to normal position and thus close the valve 13, when the pedal 19 is released by the user, and the surplus water drains off through the trap 8.

The conduit 26, communicates with the nozzle feed pipe 14, and the bowl outlet pipe '7. A flushing valve 2'? forms a part of the conduit 26, and may be opened by a caretaker by a socket wrench (not shown) said valve being operated by a wrench fitting shank 28, through a wrench clearance hole 29 formed in the fountain body. It will thus be understood that the conduit 26 and valve 2'7, by-passes the valve 13, the fountain 11, and the bowl 6, and serves to direct a stream for flushing the trap 3, and simultaneously serves to remove stagnant water from the temperature controlling coil 15, and feed pipe 14.

Another wrench operated valve 30, forms a part of the feed pipe 14 at a point below the conduit 26, which is operated through another wrench clearance hole 31, through the wall structure of the fountain body 5, to entirely close off the water supply to the fountain and valve 27, when desired.

A hinged cover 32 is provided for the fountain body 5. When closed as indicated in Fig. l and Fig. 2, said cover overhangs said fountain body on all sides and said cover droops entirely around its edge portion making a weather proof closure for the fountain bowl 6 and fountain 11. The hinge lugs 33, are formed in substantially concealed position under said cover externally of the said fountain body, and exterior corresponding lugs 34, are provided on said fountain body, said corresponding lugs mating hingedly with the cover lugs 33, and being thus pivoted thereto by means of the hinge pins 35. A downward extending lug 36, which normally extends downwardly within said fountain body is carried by said cover, and is flexibly connected to the upper extremity of the rod 21, by means of the connecting link means 3'7. When said rod is raised by the lever 1'7, to open the fountain feed valve 13, said rod at the same time through the connecting link means 3'7 and lug 35, serves to swing the cover 31 to open position as indicated by the dotted lines 38, in Fig. 2, which position is further illustrated in Fig. 3, by which arrangement it will be obvious that said cover again returns to closed position with the valve 13, when the user has finished drinking from the fountain 11, and the pedal 19, has been released. It will thus be understood that the cover 31, is ordinarily closed when the invention is not in use. When desired, however, said cover is permitted to remain in open position for periods of time without regard to the open or closed position of the valve 13 and corresponding positions of the lever 1'7, by removing the lug and link coupling pin 39.

The cover 31 is provided, preferably at a medial point with a vent cap means 40, through which air and fumes pass by natural chimney draft action from within the bowl 6, and fountain body 5, said vent being connected with the interior space of said fountain body, below said bowl, by means of the corner air spaces 41, between the edge of said bowl and the corner wall structure of said fountain body, and it will be obvious that air and fumes raise from the lowermost portion of the dry well proper 3, through the connection room 4, through said fountain body, the spaces 41, and vent cap means 40. The upward movement of air and fumes as indicated by arrows throughout the apparatus is normally caused especially in warm weather by the fact that the water fed into the water temperature coil 15, is of a comparatively warm temperature, and said water tends in warm weather to constantly warm said coil and the interior of the dry well 2, during the process of being cooled by the comparatively cool underground atmosphere within said dry well, by which it will be understood that the resulting expansion of air within said dry well causes an upward movement of same. Fumes and vapors are also thus automatically permitted to move up wardly and pass from the apparatus. Such fumes and vapors are in some instances caused by moisture seepage from the surrounding soil through the wall structure 42, .of said dry well, although it is understood that said dry well wall structure is substantially water and moisture proof. In colder weather, the air arises from within the dry well 2, due to the fact that the underground atmosphere is warmer than the overhead atmosphere.

Referring to Fig. 2 and Fig. 3, it will be observed that a lining means 43 is provided within the fountain body 5, said lining is spaced from the wall structure of said fountain body and the fountain bowl 6, and is conveniently supported at its lower portions by lugs 44, which extend from said body wall structure to said lining, and is supported at its upper portion by the flange 45, which is carried by the drain pipe '7, which passes through the upper wall portion 46, of said lining means. Said lining means serves to protect the interior of the apparatus as a whole from rapid heat conductivity through the fountain body wall structure resulting from weather conditions. The lower portion of said fountain body is flared into a swell 4'7 which forms a vertical slot 48, in which lever 17 swings when operated. A shield 49 is carried by said lever within said swell. Said flange conforms to the wall curvature of said swell and is carried by said lever in juxtaposition with said wall, and follows the lines thereof when said lever is operated by which arrangement said flange forms a closure for said slot in all operating positions of said lever thus preventing the entrance of outside air through said slot.

The rod guide 22, is conveniently mounted on the inner surface of the lining structure 43, and a lock screw 50 for said rod extends from said rod through a correspondingly threaded hole in said guide and thence through said lining structure. A wrench is applied to said lock screw through a wrench hole 51, formed in the adjacent wall structure of the fountain body 5.

The wrench holes 51, 29, and 31, are provided with outside flap means 52, which are conveniently and normally retained in closed position by gravity, and serve to be manually swung from each of said holes when a wrench is inserted therethrough for the purposes mentioned above. It will thus be understood that air communication through said holes is normally prevented by said flaps.

Notches 52 are provided in the rod 21, one of which registers with the lock screw 50 either in valve opening or closing portion of said rod, by which arrangement said rod may be locked in either position by screwing said lock screw into the respective one of said notches.

The numeral 53 designates a base plate which is interposed between the fountain body 5 and the upper edge 54 of the connection room lining. Said plate rests upon said edge, and said fountemperature controlling fountain, and valve controlled rounding soil. A hole 55 is formed in said plate, said hole conforming insize and shape to-thc lower interior edge of the fountain body swell 47.

From the foregoing it will be understood that in warm and hot weather the water supplied at the fountain 11 is cooled when passing through the coil 15, substantially to the underground temperature of the dry well proper 3. It is also understood that in cold and freezing weather the water contained in and passing through the various conduits, valves, etc. within the fountain body 5, is prevented from freezing by the comparatively warm air arising from the dry well 2.

It is also understood that in hot weather, water enters the coil 15 at a higher temperature than the walls of the dry well, for which reason there is an upward movement of air directly past said coil, and a corresponding downward movement of the air nearest said walls, and-that this circulation of air extends to movement of air within the fountain body or support 5, causing an intermingling with the air within the fountain support and dry well, thus keeping the water conveying conduits, valves, etc. within said support,

' cool as well as the fountain 11. .It is further and the air immediately surrounding said coil to move correspondingly downward; and that the air within the fountain support 5, being caused to move and intermingle with the air in the dry well, is kept warm enough from the warming of 'f the air in the dry well by said coil, to prevent freezing of the water conduits and valves in said fountain support, and to prevent freezing up of said fountain.

A damper 56 is provided in the neck 57 of the vent to by which said vent is closed off at will thus closing off the interior of the dry well 2 and the fountain body 5 from the overhead atmosphere. Said damper has an exposed wrench fitting trunnion 58, through which it is actuated.

While the description and drawing illustrate in a general way certain instrumentalities which may be employed in carrying the invention into effect, it is evident that many modifications may be made in the various detailswithout departing from the scope of the appended claims, it being understood that the invention is not restricted to the particular examples herein described.
