Patented Nov. 13, 1906.

To all whom,

Be it known FENDERSON it may concern.- that we, GEORGE CowLEs and M. SIMPsoN, c1t1zens of the United States, residing at Sacramento, in the county-of Sacramento and State of Califorma, have invented new and useful Improvements 1n Domestic Hot-Water Supply and Heating Systems, of which the following is a specification.

Our invention relates to a hot-water sup-- ply and heating system for domestic purposes.

The object of our invention is to provide a safe, cheap, simple, and ticularly adapted for heating and en hot water to a number of rooms, suc as are usually arranged together in an apartment or fiat, the heating and the hot water requiring but one boiler and one source of heat.

The invention consists of the parts and the construction and the combination of parts, as

hereinafter more fully described and claimed, having reference to the accompanying drawing, in which the figure illustrates our system.

In practicing our invention We use an ordinary gas-heater, as A, or a common kitchenrange, as B, either singly or combined, as shown, for oursource of heat-supply. Where we use a gas-heater, we may modify its constuction in such a way as to give us the fullest benefit of the heat produced by the burner.

The heater here shown is of well-known construction and comprises a casing provided with a suitable burner 2 at the bottom and a vapor-vent 3 at the top. Within the casing are arranged the vertical hot-water pipe 4 and the upper and lower water-heating sections 5 5. The upper water-heating section is in the form of a coil 5, which is the cold-water coil, since cold water is admitted directly to it. This coil is located in the ugper part of the casing A, where the heat is a ways the most intense. The lower waterheating section 5 includes disks or radial arms connected by the vertical pipe 4. As shown, the lower terminal of the coil 5 is extended to a point outside the casing A and thence extends downwardly and enters said and is connected to the lower disk or arm of the lower water-heating section, as shown, whereby the cold water admitted to the upper end of the coil 5 flows practical system par- -down said coil and through the extended lower terminal thereof and enters the lower part of the lower water-heating section 5 and thence flows backwardly through the pipe 4 relative to the flow through the upper water-heating section or coil 5. From the pipe 4 the water is delivered into the s stem.

C is an ordinary kitchen-boiler, pre erably set low and on or near the floor, so as to leave plenty of space between the top of the boiler and the ceiling for the circulation of the hot water through the radiators 6 6, as in case it is wanted to heat up the room quickly without first having to heat the water in the boiler.

Cold water from the mains enters the boiler through pipe 7. Thence it passes, through the vertical pipe 8 into the top of the upper water-heating section or coil 5 of the heater, passes downward through the same and through the lower water-heating section 5, and discharges as hot water up through the pipe 4, either into the boiler through t e inclined pipe 9 if the valve 10 is closedor el'se passes through the overhead system of hot-water pipes 11 to the radiators 6 6, which are arranged, preferably, on or 1n the walls and above the level of the boiler. With the valves 10 open the water circulates by gravity through the radiators and returns to the heater through the subjacent system of pipes 12 and pipe 8.

If desired, the water-back 13 in the range B may be coupled up with the heater A and made to supplement the latter, as shown, or, if as is not convenient or a gas-heater is not to be had the range will supply all the neces-' sary heat, the cold water entering the Waterback through pipe 14 and discharging through 'pi e 15.

he supply of hot Water for domestic purposes is taken from pipe 16, which is arranged at a point hi her than the boiler or any radiators, and istributed to the various fix: tures in the house. Any air in the radiators or coils or boiler that is liable to accumulate 1s discharged through the hot-water-supply pipe 16; hence the reason for inclining the pipes 9 and 17. The small i e 18 is for the purpose of leading any air oil om the waterpi e 8 and gas-heater coils.

Ihe radiators may be of any improved torn and form by themselves no part 0 our invention. Any sediment in the water or pipe 8 may be drawn off from time to time through the cooks 19 20.

The advantages of this system are that it allows the use of hot Water from an ordinary kitchen-boiler to be used for-all domestic puroses, including the heating of the rooms. he arrangement of the pipes and radiators -is such that the water has a gravity circulation. When the valve 10 is open, the circulation is throu h the radiators, and the rooms are heated be ore the boiler is heated. By closing the-valve 10 all the heat is diverted to the boiler, and the temperature of the rooms will remain practically unaffected. In cold weather, however, the first consideration is comfort, and hence the reason for placing the radiators above the boiler.

Having thus described our invention, what we claim, and desire to secure by Letters Patent, is-

1 An improved heating and hot-water system comprising a boiler, a gas-heater, radiators arran ed at different levels above the boiler, a co d-water-supply pipe connecting with the boiler, a vertical pipe 8 connecting the boiler with the heater said heater having a casing and upper and lower reversely-arranged water-heating sections through which the water circulates in opposite directions, said upper water-heating section having a lower terminal extended to and connecting directly with the lower terminal of the lower water-heating section, heatin section connecting with said pipe 8 and said lower water-heating section havingla delivery-pipe leading the water thereof to t radiators, and return-pipes connecting with 4 the radiator.

and said upper water- 2. An improved heating and hot-water system comprising a boiler, a as-heater, radiators arranged at different evels above the boiler, a cold-water-supply pipe. connecting with the boiler, a vertical pipe 8 connecting the boiler with the heater said heater having a casing and upper and lower reversely-arranged water-heating sections through which the water circulates in opposite directions, said upper water-heating section having a lower terminal carried outside the casin and downwardly to and connected with the ower part of the lower Water-heating section, said upper water-heating section connecting with said ipe 8 and said lower water-heating section aving a delivery-pipe leading the water thereof to the radiators, an u wardly inclined pipe 9 connecting the boi er with the delivery-pipe of the lower water-heating section, a pipe 18 connecting the upper end of the pipe 8 with said inclined pipe and serving to conduct air from the pipe 8, and a pipe 16,

arranged above the boiler and radiators and connecting with the hot-water delivery of the lower water-heating section and supplying hot waterfor domestic purposes, said pipe 16 also serving as a discharge for any air con ducted by the pipes 18 and 9, and returnpipes connecting with the radiators, substantially as described.

In'witness whereof we have hereunto set our hands in presence of two subscribing witnesses.
