3 Claims.
My present invention has relation to the provision of a hot water distribution fitting for use in systems in which hot water from a single boiler is employed for premises heating and also for heating a supply of water for domestic orother mechanical uses.
The use of a single boiler for premises heating and the heating of water for washing and other purposes is not new with me and in the last several years, has attained a fair degree of popularity. The provision of such a plural functioning system involves the purchase of considerable relatively expensive equipment and the assembling thereof in a relatively complicated .and expensive arrangement of conduit or piping.
I have had for an object the provision of a single or unitary structure which may be completely produced and assembled in a factory and which may then be taken to the job and connected in the usual way with the premises heating conduits and the hot water heating conduits. I have also had as further objects the provision of a fitting which will considerably simplify the piping appertaining to an ordinary boiler and will materially increase the efiectiveness of the respective systems with which it is connected.
I have attained the foregoing objects by means of the structure illustrated in the accompanying 3o drawings, in which-- Fig. l is aschematic illustration of a boiler and premises heating and hot water heating devices associated therewiththrough or by means oi my improved fitting.
Fig. 2 is a central, vertical section through my improved fitting; and
Fig. 3 is an enlarged sectional detail of the top of the fitting shown in Fig. 1.
I Similar reference characters have been employed to designate similar parts throughout the respective views.
The systems with which my fitting is designed to be associated include a boiler 5, preferably of standard construction, which is heated by an oil burner or stoker 8. Leading from the top of the boiler is a feed or supply pipe 7 and running to the bottom of the boiler is a return pipe or conduit 8. The premises heating portion of the systern comprises a riser or supply pipe 9 and a return pipe 10, interposed between and communieating with which riser or supply pipe 9'and return 10 is a radiator or radiators 11. The hot service water portion or the system preferably consists of a hot water supply tank 12. a feed 13 for said supply tank and a return 14 from said supply tank.
My fitting comprises a casing consisting of a lower or bottom member 15 and a top member 16. The lower or bottom member 15 of the casing has a port directly in the bottom thereof which is connected by a conduit 17 with the return 8 to the boiler and adjacent the top of the Y lower portion of the casing 15 is an additional port 18 with which the riser or supply 7 from 95 the boiler connects. This arrangement secures a continuous thermo-gravitational circulation of the water from the boiler through the lower portion 15 of the casing. The lower portion 15 of the casing is further provided with an additional upper discharge port 19 and an additional lower discharge port 20. 'With the ports 19 and l 20 are associated respectively the upper and lower ends of a heat transfer coil 21 installed in the lower casing portion 15. The upper port 19 is connected with the supply pipe 13 leading to the storage tank 12 and the lower port 20 is connected with the return pipe 14 from the hot water storage tank 12.
The upper casing member 16 is secured. to the lower casing member l5-by means of laterally extending flanges 22 provided upon the respective casing members in connection with bolts 23 which secures a dependable connection or any other means may be employed for securing an equally dependable connection between the upper and lower casing members. The upper casing member 16 is provided with a laterally extending flanged discharge stub pipe 24 and a similar laterally extending flanged return or entry stub pipe 25. The discharge stub pipe 24 communicates with a curved interior passageway 24a provided in the upper casing member 16, which pasv sageway 24a opens laterally or to one side of the center of the bottom of the upper casing member 16 and within the passageway 24a is provided a valve. seat 24b co-operating with which is a valve 240, the stem 24d of which is supported upon a pivoted arm 24c. The top of the valve stem 2441 is slotted, as at 241', to co-operate with a hooked end of a rod 26 which passes through a plug 27 screwing into an opening 28 in the top of the upper casing member 16.
The return stub pipe 25 communicates also with a curved passageway 25a in the upper casing member 16, which passageway 25a opens in the center of the bottom of the upper casing member 16. Secured in the mouth of the passageway 25a is a piece or tubing 29 which passes down through the center of the heattransfer coil 21 and the till lower end of which terminates and opens adjacent and opposite the entrance to the pipe 17 which connects the lower portions of the lower parts heretofore described in connection with the passageway 24a.
Associated with either the discharge stub pipe 24 or the return stub pipe 25 (I have shown it associated with the return stub pipe 25) is a casing 30 for an electrically operated circulating pump. The stub pipe 24 is connected with the riser or supply pipe 9 of the premises heating system and the outer end of the pump casing 30 is connected with the return pipe 10 of the premises heating circulatory system.
As will be seen in Fig. l the circulating pump in pump casing 30 is associated through conductors 31 with a thermostat 32 located in a suitable place in the premises to be heated. It
will now be seen that when the pump in, the
I have supplied the rods 26 and 26a so that the valves 24c and 250 may be manually opened if the current operating the pump in casing 30 should fail, but electric supply is now so dependable that the rods 26 and 26a are only for emergency use. Of course, it will be understood that if thevalves 2&0 and 250 are open a thermogravitational circulation through the premises heating system will take place.
My fitting will obviate the use of plural supply pipes or risers from the boiler and also plural eas es returns to the boiler. The employment of the two valves 24a and 25c wholly prevent back circulations through the premises heating system, the functioning of all of the portions of the respective systems will be accelerated and the emciency thereof increased while the operative parts are concentrated in area and easier of installation.
Having described my invention what I claim as new and desire to secure by Letters Patent is:
l. A. fitting for use in connection with hot water systems for premises heating and service water supply heating comprising an upper and. lower casing member, ports in the lower casing memher for association with the supply pipe from and a return pipe to the boiler, a pair of additional ports in said lower casing member, a heat transfer coil the ends whereof are associated with said additional ports, said heat transfer coil being concentrically disposed within said lower casing member, an upper casing member having a return channel therein, a conduit associated with and extending from said return channel through the heat transfer coil mounted in said lower casing member, said upper casing member having a discharge channel therethrough, pivotally mounted valves controlling said channels and a circulating pump casing secured to said upper casing member and associated with a channel therein.
2. A fitting for use in connection with hot water systems for premises heating and service water supply heating comprising a heat exchange casing having ports for securing a thermo-gravitational circulation of a heating medium therethrough, said heat exchange casing having a discharge passageway and a separate return passageway therein, pivotally supported valves controlling said passageways and a circulating pump casing associated with one of said passageways.
3. A fitting for use in connection with hot wa ter systems forpremises heating and service we.-
ter supply heating comprising a heat transfer casing, a heat transfer coil concentrically mounted within said casing, means for securing a thermo-gravitational circulation of a heating medium through said casing, said casing having a discharge passageway and a separate return passageway therein; said return passageway extending through said heat transfer coil, pivotally mounted valves controlling said passageways and a circulating pump casing associated with one of said passageways.
