WATER-HEATING APPARATUS.

Specification of Letters Patent.

Patented June 5, 1917.

Application filed January 29, 1916. Serial No. 75,094.

To all whom it may concern:

Be it known that I, Jusrns LAUN, a citizen of the United States, and resident of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Water-Heating Apparatus, of which the following is a specification.

This invention relates to improvements in an apparatus for heating water, and it consists in certain peculiarities of the construction, novel arrangement and operation of the various parts thereof, as will be hereinafter more fully set forth and specifically claimed.

The principal object of the invention is to provide means, or an apparatus, for conserving and applying the waste heatfrom exhaust pipes of internal combustion engines, of various types,-and those used for different purposes, to heat a volume of water which will always be hot and ready,,as well as, accessible for use for any desired purpose, as long as the engine is inyoperation, and for some considerable time after it ceases to operate. Another object of the invention is to provide an apparatus of the above mentioned general character, which shall be simple and inexpensive in construction, strong, durable and easily connected to an engine so as to utilize the waste heat of its exhaust.

Other objects and advantages of the invention will be disclosed in the sub-joined description and explanation.

In the accompanying drawing, which serves to illustrate an embodiment of the invention Figure 1 is a view partly in section and partlyin elevation of a water heating apparatus embodying one form of the invention.

Fig. 2 is a similar view of like parts showing a modified construction of the apparatus, and Fig. 3 is a similar view of the apparatus, showing a modification in the construction of the conduit thereof.

I ike numerals of reference refer to corresponding parts throughout the different views of the drawing.

The reference numeral 5 designates a portion of an internal combustion engine of the horizontal type, which may be used for any desired purpose and may be suitably mounted, but is herein shown in an un mounted condition. Located near the engine 5 and suitably supported in an upright position is a tank 6 or water container,

coil 10, which by preference consists of a single coil which has a pipe extension 11 extended from each of its ends through suitable openings in the bottom of the vessel or tank, where said pipe extensions may be securely held by means of nuts 12 engaging them and located on the inner and outer surface of the bottom of the vessel as is clearly shown in the drawing. Connected to the lower portion of one of the extensions 11 by means of a. coupling or union 13, is the outer end of the exhaust pipe 14 of thelen gine 5 and connected to the lower portion of the other pipe extension 11 by means of a coupling or union 13 is a pipe section 15, which may be of elbow shape and has mounted thereon a muflierslti of any well known or preferred construction. By the foregoing arrangement of the parts, it is obvious that the vessel or tank 6 may be supplied with water so that the same will submerge the coil 10 and pipe extensions 11, when it is apparent that as the heat and exhaust matter from the engine is discharged through the exhaust pipe 14 it will pass .from thence through one of the pipe extensions 11, thence around the coil 10 and thence through the other pipe extension 11, and from thence out through the pipe section 15 and mufiier. In this operation it is obvious that the water within the tank or vessel 6 will be heated by means of the waste heat of the exhaust of the engine and that there will thus be afi'orded avery eficient and inexpensive apparatus for heating water and holding the same until it is desired to be used. 7

In Fig. 2 of the drawing I have shown a modification in the construction of the apparatus, and have also illustrated it in said figure as being used in oonnectlon with a vertical engine 17 instead of a horizontal engine as shown in ,Fig. 1 and ]l1St above described. In this modified construction the tank or vesselmay be suitably supported at a point near the engine 17 and has communication with a water jacket 18 of the en gine through pipes 19 and'x20, the -former of which leads from the upper portion of the water jacket to and communicates with the upper portion ofthe tank while the pipe 20 leads from the lower portion of the water jacket of the engine to and communicates with the lower portion of the tank or vessel. By this arrangement it is apparent that a continuous circulationof water will be created through the water jacket of the engine and the tank. In this modified construction a pipe bend or loop, which is designated as a whole by the reference numeral 21 is, located vertically in the tank 6 and said pipe loop' consists of two members 22 which are connected at their upper ends by a transverse portion 23. The lower ends of the members 22 of the loop areextended through suitable openings in the bottom of the tank and may be firmly secured in place in' said gaging said members on the inner and outer surface of the bottom of the tank or vessel. Connected to one ofthe members 22 of the pipe loop 21 by means of a union or coupling 13, is the exhaust pipe 24 of-the vertical engine 17 through which the heat and exhaust matter of the engine will be discharged into the member 22 of the loop 21 and from thence it will pass through the portion 23 of said loop and from thence downwardly through the other member of the loop, and thence out through a pipe section 25, which may be connected to the last named member of the pipe loop by means of a union or coupling 13 or otherwise. This pipe section, vided with a mufiier 16 of any wellknown or preferred construction.

In this modified construction of the appae ratus, it is obvious that the water will be heated within the water jacket of themglne, p e the-pipe 19 into the tank 6 and thence through 20into the 'lower portion of the as it becomes heated, it will rise to again pass through the pipe 19 into the vessel or tank, which operation will be continuous as long as the engine isoperated. In addition to this means of heating the water it is obvious that the heat from the exhaust of the engine will also be utilized for the purpose of heating the water in the tank or vessel.

In Fig. 3 of the drawing is shown still anopenings by means of nuts 12. en-' like the pipe section 15, .is proand will pass therefrom through the other modification in the construction of the apparatus, in which the construction and arrangement of the parts are identical with those shown in Fig. 1 and above described, except that the muffler 16 is placed within the tank 6 and communicating at each of its ends with a section of one of the pipe extensions 11', and by preference with the said extension to which the exhaust pipe of the engine is connected, although, if desired, the mufiier may be placed on the other pipe extension 11 but within the tank. 7

Having thus fully described my invention, what I desire to secure by Letters Patent 1s-- '1. In an a paratus for heating water, the combination with an engine, of a tank separate therefrom and independently mounted, means independent of the engine for supplying water to and discharging it from the tank, a conduit located within the tank and extended through the same at its inlet as well as its outlet portion, said conduit having communication at onev of its ends with the exhaust of theen-gine.

2; In an apparatus for heating water, the

' on said conduit.

3. In an apparatus for heating Water, the combination with an internal combustion engine having a water jacket surrounding the same, of a tank separate from the engine and independently mounted, a pipe leading from the exhaust of the engine to and into the said tank and having a portion extended through the tank for the discharge of the exhausts of the engine, a pipe section carrying a mufller attached to the discharging end of said portion of said pipe, pipes connecting the upper and lower portions of the water jacket of the engine with the upper and lower portions of the tank, and means independent of the engine for supplying water to and discharging it from the tan JUSTUS LAUN.
