PORTABLE WATER HEATER.
To all whom, z'trmag concern:
Be it known that I, Lnoroia) MARX, a citi zen of the UnitedStates of America, reside ing at Birmingham, in thecounty of Jefter son and State of Alabama,- have invented certain new and useful Improvements in Portable Water Heaters,of which the following is a'specification.
' vide a novel type ofboiler with a series of,
This invention relates to an improvement in portable water heaters for boilers suitable for domestic purposes, ny object being to provide a simple and inexpensive water heater which will meet the existingdemand for such where no running water system or gas mains are available, and which isparticularly suitable for use on farms and in mining camps. A furtherobgect of my invention is to prothe heater bearing reservoir'and with a suit able steam discharge and air vent leading fromthe latter overhead into the upper reservoir. .7 y i g My invention also comprises the novel de-, tails of construction and arrangements of parts which are hereinafter, more particu larly described, and which in their preferred embodiment only are illustrated inthe accompanying drawings forming part of this specification, and in WhlCl1'2- Figs. 1 and 2 arerespectively a side ele-. vat'ion and plan of my water heater and boiler. f v a I Fig. 3 is a sectional elevationof my invention taken'on the line 3-3 of Fig. 2.
Fig. 4 is a sectional plan taken-on the line 4-4 of Fig. 1. 1 Fig. 5 is a sectional elevation taken on the line 55 of Fig. '1, while 6 is the rear elevation of the stove alone showing the location of the holes permitting the insertion of the water tubes.
Similar reference numerals refer to similar parts throughout the drawings.
Application filed March 10, 1922. Serial No. 542,720.-
With reference to Figs. 1 and 2, I show aboiler 1 of any suitable material and ca pacity supported on a base 2 with out-lets 3 and 4 forhot and cold water. A reservoir 5 is supported by the brackets 6 on the boiler 1, said reservoir being open at its upper end to-facilitate filling. Leading from the bottom of the reservoir and depending into the b'oiler l within an inch or so of its bottom isa feed pipe 7 which keeps the boiler 1 filled with water as longas the reservoir?) has any water therein. A'vent and overflow pipe 8 is provided for the exhaustion of air in the boiler while filling and for dischargingsteam, and overflow water from the boiler into the tank. l
The stove is formed of sheet metal and is madeup of the following elements; a body portion 9 provided'with a front hopper 10 to receive'the fuel. ,This hopper is covered with. a hinged top 11 provided with a simple catch 12- as shown. There is also a smoke outlet and pipe 13 fitted to the top of the body portion 9 ofthe stove. A grate 14 is hingedfto the stove with a latch. 15 adapted to hold .the grate in normal position. I show an ash box 16 provided with a handle 01 drawer .pulljlZ, this box ;.being adapted toslide back and forthby means of tongue and groove guides 18 formed on the upper side edges of thebox and the lower corresponding lower side edges of the stove. Toperinit of. the easy handling of the ashes, the grate .1 1 is pivoted at 19 so that upon the release of the latch the grate will fall/as indicated in dotted position,
Fig. 3,. thusduinping the A fuel and ashes thereon into the ash box 16, The grate 14 is, then lifted back into position :by thelever 20 keyedto the grate shaft 19 and latched 'in its operating position.- v The rear walljof the stove 9, and box 16 areforn ed in an arc toconformwvitli the curvature of the'boiler 1 and. inthe rear stove wall are holes 21 which are arranged to reg sterwith four water tubes 22projecting from within the i boiler 1,'llh8 outer ends 23 of. these tubes that enterthe stove being closed-while the other ends 24 inthe boiler are bent upwardly, as shown, and areopen the'tubes being; soldered or suitably fixed to the side of the boiler. When in operation the pro jecting closed ends 23 of the tubes 22 are Within and disposed on each side of the stove, and they are surrounded by the fire therein, so as to heat the Water in the tubes.
In order that the stove may be held firmly against the side of the boiler yet without permanently affixing same, I provide a metal strap 25 adapted to encircle the boiler and the stove and provided with any suitable tightener means to clamp the stove firmly tothe boiler, the weight of the stove being supported by the tubes and this strap.
In orderthat combustion of the fuel introduced into the stove will take place a series of draft holes 26 are provided in the lower portion of the stove beneath the plane of the grate while same is in normal position.
in operation, water is poured into the tank 5 and runs therefrom through pipe 7 intoand fills the boiler up until the latter is entirely full 'and any desired reserve of water remains in the reservoir 5. The grate 14 is latched in its operating position and 'the lid 11 is lifted and charcoal or other suitable fuel is introduced'intothe stove and ignited. The resulting flames encircle the enclosed ends 23 of the tube 22 and rapidly heat the small voluine'of water con'tainedin each -tube.
This heated water flowsout'ofthe tubes and upwardly towards the top of the boiler 1 and there collects. Should the user desire hot water, the same is drawnfrom the upper outlet 3.but should "he tlesirecold water or to clean out the boiler he utilizes-the lower out- K matic and perfectlysafe.
In addition to the heating effect or the flames on the-tubes, the stove by its extended surface contact withthe side of the boiler serves also to rapidly heat the waterin the boiler. I
Thoughl have desoribedwith great particularity the details of'the preferred enibodiment of my invention'herein shown, it is nottobe construed that'I'am limited thereto, as, changesfin arrangement and substitution of equivalents may bemade by those skilled in the art without departing from the invention as defined in the appended claims.
Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is 1 1. A portable water heater comprising a boiler, a fuel burning stove mounted on the side of the boiler, and tubes communicating with the side of the boiler and projecting into the stove, said tubes having their ends within the stove closed and their end Within the boiler open and upturned.
2. In a" portable water heater, a boiler having a series of tubes opening thereinto and having closed ends which project laterally outwardly from the boiler, and a stove having a side wall provided with apertures arranged to permit saidprojecting tube ends to pass therethrough into the stove.
3. In a portable water heater, a boiler having a series of tubes opening thereinto which project laterally outwardly from the boiler, a" stove having a side wall provided withapertures arranged to receive said projecting tubes, and means to clamp the stove to the side of the boiler.
d. In a portable water heater, a boiler having a series of tubes opening thereinto and having closed ends which project laterally outwardly from the boiler, a stove having a side wall provided with apertures to receive said projecting tube ends, and means to clamp the stove to the boiler, the stove having its "face adjacent to the boiler shaped to conform to theboiler contour.
5. In portable water lieater, a boiler having water tubes projecting laterally therefrom, a fuel burning stovehaving a side wall curved to conform to the boiler and provided with openings to receive said tubes, a strap adapted to surroundthe boiler and clampthe stove in'pos'itionon the side of the boiler, and agencies to supply water-to and to vent-the boiler. I
6. In a portable water heater, a boiler having water tubes projecting laterally therefrom with-their outer ends closed, a. fuel burning stove having a side wall curved to conformto the boiler and provided with openings through which said tubes project, a strap adapted to surround'the boiler and clamp the stove in position against the-boiler, an auxiliary reservoir mounted on top of the boiler, and pipes're'spectively connecting the lower and upper ends of the boiler and reservoir.
In testimony whereof'l affix my'signature.
