Applicationfiled. February 17, 1913. Serial No. 743,790,

To all whom it may concern Be it known that l Josnrrr B. Mownvi a citizen of the United States, and resident of jt lcvela nd. in the county of Cuyahoga and which char; cterized by practicability in construction and slight initial. cost and in which the water is continuously and repeat-- c lly exposed to a l'ieating medium, and the The device is adapted for use as an in stantaneous water heater for all domestic uses, and also canbe employed in a hot water circulrtinp system for heating a dwelling house, or other edifice.

The invention comprises a series of holow water heating units having a central ineans for communicating with each other and inclosed in a non-radiating casing in which a noirconductor such as asbestos is iuclosed. 'llhese units are superimposed above each other in staggered relation and separated by passages for circulation of the heating" medium.

The construction and arrzmgcinent of the several units and means for connecting and heating the same as hereinafter more fully (lrscribed shown in the accompanying drawings and] specifically pointed out in the claims.

in the accompanying drawings Figure l is a vertical central section of the device; Via. is a transverse section on line .aa l I; Fig. 3 is a transverse section on line 7) b Fig. 1. t is a vertical section of a-easing showing the construction arranged to prevent radiation of heat therefrom.

ln these views A. is the casing preferably forinedof two thin sheet metal tubes" inclosling plates B B of corrugated sheet asbestos which etliciently prevent the outward radiation of heat C, C are burners employed for supplying current of hot air to the heater, but any other heating device can be readily employed for this purpose.

1s niost eiliciently disposed l) is the lowest hollow water heating unit into which the water flow is led at one eX- trernity at E. This unit comprises a fiattened tube provided with a vertical fork shaped partition the stem portion F of which is placed upon the centerline of the unit and. preferably spaced from the inlet opening thus permitting the water to flow equally on both sides of it. The sides F, F of the forked extremity extend nearly to the opposite end of the unit leaving a space at their ends and between them for flow of water; substantially centrally placed in the upper wall of the unit in the crotch. of the forked partition is the upwardly directed outlet opening G and a short tube or union connects this opening with. the unit if above. In this manner the water is first compelled to flow the entire length of the unit and to return between the forks to the central outlet, thus giving it two ere posures to the heated surface of bottom and sides of the unit and raising the temperature'quickly before itflows upward to the next unit. The units superimposed upon the lowest unit provide for a return circula-- tion inv a somewhat different manner, as follows: A vertical partition H runs through this hollow unitand is arranp'ed on two vertical planes, connected together by a transverse and prefenibly $5 shaped member H at the center of the unit. Upon one side of this 3 shaped partition in the bot tom. of the unit is located the inlet opening l leading; from the opening G below anl at the other is located the outlet openinn J in the top plate of the unit, which leads to the unit above. The water entering the unit from below through the opening I must divide its How and pass entirely around both ends of the vertical partition which are spaced from the end walls of the unit at K, K to provide passages for this purpose. The water then flows back from the ends to the outlet opening on. the other side of the partition. Each unit above is constructed. in substantially the same inanner, and the upper and lower walls of the units are preferably horizontal to equalize the flow over all parts of the units. so that no portion of the water can be heated to a higher degree of temperature than another. The complete and continuous circulation of the water thus afforded throughout the heater and the repeated flow through each unit in sures raising the water quickly to a high degree of temperature, and if heat should be irregularly applied to the bosom of any one unit the water unit-st all travel. the entire surtaceoil each bottom and a i'lnrl orin cc of temperature result 'l he will rise as it incomes will .luitter and thus permit the entrance 0'? cold water as fast as it is drawn of; from above. These units bear a sta red relation. to each other at their col:

for he heated products of oinni, which is applied directly ti foughout the length at each unit. line hi conduo's awavthe products of combustion, and is preferably attached to the cover or hood. Small blind stave 9', may be employed to prevent wal a. of 1; units and cod eject the upper and lower alls. Openings P, P are shown placed maposito to each other to introduce a cleaning tool. These openings screw threaded. that stoppers er plugs of any character can be inserted in them Having described the invention what I claim as new and desire to secure by Letters Patent" is:

1. In awater'heater, a bottom unit comprising a hollow chamber, provided with an inlet opening at one end, and a central outlet opening in its upper wall, and a vertical forked partition longitudinally disposed in said chaml er, and having the extremities of the stem end and forks spaced from the end walls of the chamber, the stem end adjacent to the outlet opening, and water heating units superimposed above said bottom unit,

said superimposed unitsfprovided with vertical longitudinal partitions spaced at their ends from the ends of the chamber, and provided fitll inlet and outlet openings on opposite sides of said partitions andan inclosing casing for all said units.

plying device, and a series of superimposed horizontal staggered hollow water units vri hin said casing separated to form a circul'ating passage for the heating medium,

the lower unit provided with a water inlet,

at one end, and with a substantially central outlet opening in its upper wall, said lower unit having a vertical fork shaped partition therein, the sleeve of the fork adapted to divide the water flow into equal portions at the sides of the unit, and the branches of the fork adapted to receive the flow from the said sides and return same to tne outlet opening, the upper units provided each with a vertical portion extending in different planes on each side of its longitudinal ceniius providing a tortuous ter, and connected by a transverse partition andhaving its inlet and outlet openings arranged one on each side of said transverse portion, wherehythe flow oi. water-is first directed h ngitudinally of the unit toward its ends, and afterward is returned toward the center thereof, the outlet opening of one unit communicating with the inlet opening oi": the next adjacent unit.

.3. in a water heater, a bottom unit comprising a closed chamber having an inlet opening at one end and an outlet opening in its upper wall, and a forked partition in said chamber, having extremities spaced from the end walls of said chamber, and having the stem end of the forks adjacent to the inlet opening of the chamber, the said outlet opening being arranged between the forked extremities of said partition.

a. In a water heater, in combinatioma closed bottom chamber h aving an inletopenfor water at one end andan outlet' openi. Q in its upper wall, and provided with a forked partition spaced at its ends from the end walls of the chamber and having its stem end adjacent to and in line: with the inlet opening, the forks of said partition in closing the outlet opening, and a second chamber superimposed upon said bottom 0 chamber, said second chamber provided With a longitudinal partition spaced from the end walls of said chamber, and with inlet and outlet openings arranged on opposite sides of said partition, the inlet opening inthe second chamber communicating with the outlet opening in the bottom chamber, 7

ln a water heater, a water circulating unit comprising a closed chainberhaving an inlet opening in the bottom and an outlet opening in the top, said openings being spaced apart, a transverse partition in said I v I chamber separating said openings, and-ver- 2. In a water hea er, a casing, a heat supti' l artition walls extending longitudinallv from the ones of said partitiom andi having their outer ends spaced from the end walls of said chamber.

6. In a water heater, a water distributing and circulating chamber, said chamber provided with spaced openings in its upper and lower Walls, and a partition separating said openings, and extending partially to the end walls of said chamber.

In testimony whereof, I hereunto set my hand this 11 day of January, 1913.
