To all whom t may conce/ra.'

Be it known that we, @Hannes A. Mo- CARTY and 7M/DER A. JoNns, citizens of the United States, and residents of Plymouth, in the county of Plymouth and State of Massachusetts, have inventedY a new and Improved Vater-Heating System, o-f which the following is a full, clear, and exact description.

This invent-'ion relates to improvements inwater heating systems, and has particular reference to such a system as used in connection` with washing machines.

In large establishments, such as woolen mills where batteries of washingmachines are employed it has beenfound that the use of excessive amounts of fuel,-. such. as coal, has been necessary in.f order to maintain the water used inI the washing machines at proper temperatures.

It is proposed by the present i-nvention` to eii'ect an economy in fuel consumption by the provision of an apparatusby means'of which the temperature of col-d water isincreased previous to its entry into the washing machines 4through the utilization of water discharged from said machines.`

Another object is to provide an apparatus of simple and inexpensive construction and which is effective in carrying out thepurpose for which it is designed.

The above and other objects willappear more clearly from the following detailed description, whentaken. inconnection with the accompanying drawings, which illustrate a preferred embodiment of the inventive idea.

In the drawings- Figure 1 is a diagrammatic viewshowing the application of the invention to a bat tery of washing machines, the tank' being in section; and

Figure 2 is a plan view of said tank.

Referring morev particularly to Figure 1, a pair of washing machines comprising a battery are indicated by the numeral 5 and these machines are supported in any suitable manner above the tank or vat 6- forming one of the essential features of thev present invention. A water heater usually employed in connection with the washing machines 5 is also conventionally shown in Figure 1 and indicated by the numeral 7. This heater may be of any desired type, such as an instantaneous heater, and is utilized to increase Serial' N01.. 698,812.

the teirrperature of. the water previous to` its being fed into the washing machines through the Amain feed. pipe 8 and the branch. feed pipes 9, each. ofthe latter pipes leading to one of said machines. The water to' be supplied to the machines 5 may be taken from any suitable source and is pumped to saidfmachines by means of a suitable pump 10,. also conventionally shown in Figure 1. Should it be desired;y to supply cold water direct-ly tothe machines 5 this may be done through the vpipe 1'1 which.` is connected by branches 12. to. said machines, the flow of water through; said pipe 11 being controlled by a gate valve 13insaid pipe. However, should it be desired to heat` the water before entering the machines the Valve 131 is kept closed` so: that the cold water from the source of supply willnot enter'the pipel1,but flow downwardly into the inlet pipe 14which projects into the tankv 6 to al point adjacent the bottom thereof. l Associated with the inlet pipe 14- is an outlet pipe 15 and connecting these twovpi-pes arel series of coils 1'6` each including a pair of pipes having ad `jacent ends connected to the pipes 14 and 15 and their opposite ends connected by a union 17 ,said coils combining to formy a primaryA heating 'unit designed to increase; the temperature of the water iowingfrom the `source of. supply before entering the heater 7. The iiow of water through the inlet pipe 14 is controlled by agate valve1`8 which is opened. lwhen it is desired to heat thel water and which is kept closed when cold water is fed directly. tothe machines through the pipe 11..

The tank. 6, which is. formed of` concreteV or any other desir-able material, is provided at one end with spaced partitions 19' and 20, the former' of which extends from thev openy top of the tank toa point adjacent the bot.- toml thereof, while the latter partition which` is interposed between the partition 1.9 and one end of the tank extends; from the bottomy to. a poi-nt near the top, `the height of said partition 2O determining the water level*` inthe tankl when the same is supplied with the heated water discharge fromh the machines 5, as'will-,bepresently described. The water in the tank 6 which overflows the partition 20 is carried away through a-suitable drain 21. Should it be desired to completely empty the tanka gate valve 22 is employed pumped into the system by the pump 10` before it reaches the heating element 7 the valves 27.

vopposite end of each pipe 25 is positioned over the tank adjacent the end thereof opposite the partition 20. A normally closed gate valve 26 in each of the pipes 25 controls the flow of water from the machines 5 to the drain outlet 21 while similar valves 27 control said flow from the machines into the body of the tank. Should it be desired to increase the temperature of the water used water in the machines 5, which has been previously heated to the proper temperature, may be discharged from the machines 5 into the tank 6 by opening the This water rises to the level of the top of the partition 2O and in so doing the coils 16 are immersed therein and heated by said water so that as the water from the inlet pipe 14 passes throughY the coils its rtempe'rature is increased materially before it enters the inlet pipe 15 from whence it flows to the heater 7. Here the water is raised to the desired temperature and then fed through the pipe S and branch pipes 9 to the machines 5. In the event that it is desired to discharge the water from the machines 5, as at the completion of the operation thereof, without permitting said Water v to flowv into the tank 6 the valves 2G are `opened ythereby permitting the water from the machines to flow through the drain 21. lVhat is claimed is.: y 1. The combination with a washing ma chine and a heating element connected with the, machine for supplying heated Water thereto; of a tank above which said machine is supported and into which the water in the machine is directly discharged, a heating .coil in saidtank for raising the temi; E'perature vof water fed to said coil from a source of supply, and a connection between said coil and heating element for feeding the water to the latter subsequent to its pas` sage through said coil.

2. The combination with a washing ma chine and a heating element connected with the machine for supplying heated water thereto; of a tank above which said machine is supported, a heating coil inV said tank for raising the temperature of wate fed to said coil from a source of supply, a connection between said coil and heating element for feeding the water to the latter subsequent to its passage through said coil, and means for permittinof the heated water from said machine to be discharged directly into said tank to heat the coil therein.

3. The combination with a washing machine and a heating element for supplying heated water thereto: of a tank having a drain outlet, a heating coil in said tank for raising the temperature of water fed to said coil from a source of supply, a connection between said coil and heating element for feedine water to the llatter subsequent to its passage'through said coil, means for permitting the flow of heated water from said machine directly to said tank to heat the coil therein,` and means for discharging water from saidmachine directly through said drain outlet without affecting said coil.

4. The combination With a Washing machine and a heating element forvsupplying heated water thereto; of a tank having a partition therein forming a compartment in the tank and providing anl overflow for the tank below the level of the topr thereof, a drain outlet on one side of said partition, water feeding means on the opposite side kthereof connected to a suitable source of supply and also to said heating element, means for dischargingheated water from said machine into said tank to immerse said feeding means whereby the temperature of the water passing therethrough is increased prior'to its entry into said heating element, and means also permitting the discharge of water from said machine into said tank and through said drain outlet without affecting said feeding'means.

5.. The combination with a Washing ma- `chine and a heating element for supplying heated water thereto; ofa tank having a vpartition therein providing an overflow for the tank below the level of the top thereof, a drain outlet on one side ofsaid partition, water feeding means on the opposite side thereof connected to a suitable source of supply and also to said heating element, means for discharging heated water from said vmachine into said tank to immerse said feedingmeans whereby the temperature of the water passing therethrough is increased prior to its entry into said heating element, means also permitting the discharge vof water from said machine/into said tank and through said drain outlet without affecting said, feeding means, and a valve associated with said partition for permitting the tank to be Ven'iptied through said drain outlet.
