HEATING SYSTEM.

Specification of Letters Patent.

Patented July 31, 1917.

Application filed January 9, 1915, Serial No. 1,371. 7 Renewed December 19, 1916. Serial No. 137,811.

To all whom. it may concern Be it known that I, CHARLES H. TAYLOR, a citizen of the United States, residing at Oakland, in the county of Alameda and State of California, have invented certain new and useful. Improvements in Heating Systems, of which the following is a specification.

This invention relates to improvements in heating systems and more specifically to a heating system in combination with a domestic hot water supply. The principal obect of my invention is to produce a clean, safe, economical, and eflicient, dependable system supplying hot water for domestic purposes and to a heating system by the use pf a single gas burner and regulator there- Another object is to so construct a system under'normal conditions that'the water from the radiators does not pass into the boiler.

Another object of my invention is to allow the water which normally circulates through the radiators to pass into the boiler when the water supply therein is heavily drawn upon.

With these and other objects in view my invention consists in the novel construction and arrangement of connections as herein described and more specifically pointed out in the'appended claims.

Reference being had to the accompanying drawing forming a part of this specification.

Figure 1 is a view in elevation of my improved boiler and the connections therefrom to the heating system and domestic water supply.

Fig. 2 is an enlarged sectional view through the lower part of the boiler.

Referring to corres onding parts by the same numerals of ref drence, 1 denotes the boiler having the usual inlet and outlet 2 and 3 respectively, the outlet 3 being connected with the domestic fixtures one of which is illustrated at 4. The bottom of the boiler is provided with the recessed portion 5, and extending from the upper portion of this recess, through the top of the boiler is a flue 6 by which products of combustion escape from the cavity 5. Located in this recess are two heating coils 7 and 8, the former of which is primarily intended for heating the water for the domestic supply and the latter of which under normal conditions heats the water to the radlator system.

Extending through the center of the bottom 9 and in-threaded engagement therewith is a special fitting 10 and to the end projecting within the boiler is attached a pipe 11, which extends upwardly and ter- Inmates adjacent the top of the boiler. The

upper end of this special fitting contains a division wall 12 extending from a point above the bottom 9 to a point below the same. Within the boiler is provided an opening 13 providing a passageway to the interior of the fitting below the division wall 12. The lower end of coil 7 is connected to the fitting 10 adjacent its lower end while the upper end of this coil is connected to the fitting adjacent its upper end and on the opposite side of the division wall 12 from the opening 13. In this manner a circulation of water is secured from the bottom of the boiler through opening 13 down the one side of the division wall 12 through the fitting 10 to the lower end of the 0011 7. As the water becomes heated it passes upwardly through the coil into the fitting on the opposite side of division wall 12 and upwardly through pipe 11 into the top of the boiler.

Coil 8 has its upper end connected to a pipe 14, which extends upwardly through the flue 6, being brought out from the side thereof and connected by suitable pipes 15 to the radiators 16. The lower end of coil 8 is connected by suitable fitting 8 to the side outlet of T 19. On pipe'l i just below the flue 6 is provided a drip cup 17 so that the water which condenses on the comparatively cool walls of fine 6 is caught by this drip pan and is again vaporized and passes oif through the flue 14.

In threaded engagement with the lower end of fitting 10 is a short nipple 18 to which is attached the T 19, and the lower end of the coil 8 is connected to the side outlet ofthis T. Below the latter is connected a second T 20 from the side outlet of which extends pipe 21 to a sediment trap or filter 22. The return pipe of the radiators, denoted by 23. is attached to the opposite side of the filter, and a thermostatic regulator 25 is connected to'the bottom of the l 20, which has its thermostatic element 25 extending upwardly into this "5, so as to regulate the temperature of the radiators. 26 denotes the gas supply pipe entering the thermostatic valve and 27 the supply from the valve to a gas burner 28. The recessed lower portion of the boiler is provided with a door 29 to allow the ready inspection of the coils and burner within the recess, and the whole device is supported on a suitable structure 30'.

Just outside the top of the boiler pipe 1a and pipe 3 are cross connected by the nipple 31 and in the usual operation of the system the water in the boiler circulates as previously described and the water from the radiators circulates upwardly through the coils 8, pipes 14 and 15 to the radiators and from the latter through pipe 23 to the filter 22 upwardly through the 'ls 20 and 19 to the coil 8.- Under normal conditions little or no flow takes place through the connection 31 or through the nipple 18. it, however, a very large amount of water is drawn 0d from the boiler through one of the domestic fixtures then the water ascending pipe 1d is hotter than the water which is drawn 0d from the boiler, consequently, the hotter water in pipe 1% will flow through the connection 31 into pipe 3 and a corresponding amount will flow downwardly through the nipple 18, T 19 into the bottom of coil 8. This in turn operates the thermo stat and allows a greater volume of gas to flow 'therethrough. As the water within the boiler and the radiator reaches uniform temperature the flow through the nipple 31 and through the nipple 18 no longer takes place, and when the water in the boiler and radiators reaches the predetermined temperature the gas is closed ed to the amount sufiicient to maintain this temperature.

On the other hand, if no water is drawn through. pipe 3 and the water within the heating system is quickly cooled as when a new radiator is opened, the hot water will fipw from the tank through bypass 31 into pipe 14 and into the radiators. This causes a slower flow through pipe 14 below the bypass 31 and consequently the water has time to reach a higher temperature than otherwise.

supplies water to its respective system, but under abnormal conditions both coils are used to heat the colder system.

It will thus be seen that l have provided a system for furnishing domestic hot water supply and heating radiators from the same unit, thus materially reducing the cost oi such installations. and furnishing an economical and eiiicient system.

Thus; under normal conditions each coil What 1 claim as new and wish to cover by Letters Patent is 1. A combined hot water supply and heating system comprising in combination, a

reservoir tank, a heating coil, a connection from the lower part of said tank to the lower part of said coil, a connection from the upper part of said coil to the upper part of said tank, a second heating coil, a riser from the upper part of said second coil, one or more radiators connected to said riser, a return pipe from said radiators to the lower part of said second heating coil, a bypass connecting the lower ends of said coils and a second bypass connecting the upper part of said tank to said riser.

2. A combined hot water supply and heating system comprising in combination, a reservoir tank, an exit pipe leading therefrom, a heating coil having its lower part connected to the lower part of the tank and its upper part connected to the upper part of the tank, a second heating coil surrounding said first mentioned coil, a riser extending from the upper part of said second heating coil, radiators connected to said riser, a return from said riser to the lower part of said second coil, a bypass between said exit pipe and said riser, a second bypass between the lower ends of said coils and a thermostatic regulator extending into said last mentioned bypass.

3. A combined hot water supply and heating system comprising in combination, a reservoir tank having a hollow base, a flueextending from said base through said tank, a heating coil located in said base and provided with connections from the top and bottom to the top and bottom, respectively, of the said tank, a second coil surrounding said first mentioned coil, a riser extending through said flue and connected to the upper part of said second mentioned coil, radiators connected to said riser, a return from said radiators to the lower part of said second mentioned coil, a water exit pipe extending from the top of said tank, a bypass connecting said exit pipe to said riser adjacent said tank, a bypass connection between the lower ends of said coils, a burner common to both of said coils, a gas supply pipe, and a thermostatic valve in said gas supply pipe, the thermostatic element of said valve extending into said last mentioned bypass.

ln testimony whereof I aflix my signature in presence of two witnesses.
