Appiication ied August is, 1924. serial No. 732,596.

i washb'oilers and for various other purposes.

An object of the kinvention is to provide a Vstove that may be quickly set up for use, more particularly for domestic purposes, to efliciently and economically supply heat at such' times as may be required, and which may be readily removedand stored so as to be in good conditi-on for immediate use when again needed.

Another object is to provide a laundry stove which shall be adapted for use in houses, or on porches or in yards in sinnmerseasons and not'be liable to suffer injury because of inclement weather conditions, but which shall be so constructedA as to be adaptedto be quickly and conveniently removed from place and hung VupV on a hook or nail which may be secured to a wall.

A. further object is to provide an improved laundry stove that shall permit of being con# structed entirely. of `such material as is not liable to be broken' when the stove is roughly used or handled,'andwhich shall permit of light-weight but stiff structure and of such material as may be cheaply obtained from merchant stocks of metals, and which shall be 'durable and economical in use.

lith the above-mentioned and other ob;

jects in view, the invention consists in a skeleto'nlilre portable gas-burning stoveh-av-`V ing improved construction generally andV on reduced scale.

Similar reference characters 'in the differentfiguresof the drawings indicate cor-v responding eleinents or features of construction-herein referred to.

The improved stove comprises an oblong vframe which is composed of'L-section angle iron and having longitudinal top' plates 1 and 2 and transverse top plates 3 and 4l, all connected together with slightly curved corners, the longitudinal plates having vertical plates 5 and 6 extending downward from the outer edges thereof, the transverse plates having vertical plates 7 and 8 extending downwards fromthe outer edge thereof to constitute stiflening members and also yfacing plates. rlfhe stove vis provided with four

short legs

9, 9 secured to the corner portions of the frame, each legbeing composed of il section iron and su'itably'shaped so that the upper portions closely lit against ythe inner sides of the verticalV Iplates of the frame to which thelegs are rigidly secured, preferably by means of bolts'and so that the top plates shall lrest 'directly upon the tops of the legs. One of the transverse members of the frame supports two hangers 10 and 11 and the'opposite transverse membei' supports av hanger member 12, each hanger being connected to the ytop plate of the member by means of a head plate 13 on the top of the mainv portion of the hanger. The plan dimensions .of the frame correspond approximately to that Yof a .conventional wash-boiler, or may bel slightly longer and broader, externally.

The stove comprises also a .metallic pan consisting` of a bott'om'plate 14' and acontinuous side wall v15 thereon, the top of the wall having flange 16 which preferably extends inwardly"` and has bolt holes 17 therein. The pan is of such length and width that the wall thereof'ma'y be located in contact with/the under side of the top plates of the frame, the flange 16 of the pan being` secured directly to the plates by means of bolts 18 that are received in the bolt holes 17. The hangers are arranged in the pan and the head plates of the hangers are arranged in contact with lthe under side of the flange 16 and directly secured thereto by` means of the bolts 18. vOne of the functions of the pan is to partiallyencasea gas-burner in a manner to assist in controlling heat, as A The in a combustion chamber or firelbox.

Vpan has a depth approximating one-'half the length of the leg member ofthe stove. yA gas-burner is provided which is composed of piping and fittings and comprises a T head 19, nipples 2O and 21 connected to opposite sides of the head,

elbows

22 and 23 connected to the nipples respectively, and tubular burners or pipes 2st and 25 connected to the elbows respectively. rEhe burner pipes extend through the hangers and '11 respectively and each pipe has a cap 26 secured thereon adjacent to the ougter side of the hanger, being near to the wall of the pan. A suitable gas-mixer 27 is made use of which has a neck 28 that is screwed into the T-head 19, the neck being slightly tapered and inserted through a hole 29 in the wall of the pan and also through the hanger member 12, the tapered neck being fitted closely in the holes, so as to tend to draw the caps 26 close to the hangers 10 and 1 for holding the burner tightly in place. A jet nozzle 30 is arranged in connection with the mixer, as is customary and has a gascock 31 connected thereto, integrally or otherwise, the gas-cock having a neck 32 adapted to have a gas-supplying hose or pipe connected thereto. Preferably the under side of the mixer has a boss thereon to which a b acket arm 33 is secured which has an upward extending relatively angular arm 35 thereon that is secured to and supports the neck 32. The burner pipes have each a row of jet-holes 36 on one upper side portion and a separate row of jetholes 36 in the opposite upper side portion thereof. rlhe burners are spaced a considerable distance apart so that the flames therefrom shall be directed to the bottom of the wash-boiler nearly over the whole surface thereof but more directly to those portions adjacent to the longer sides of the washboiler.

The pan or combustion chamber structure prevents wind currents from interfering with proper combustion when the stove is used out-doors, but to admit sufficient atmospheric air to promote proper combustion the bottom 14 of the pan has a suitable number of apertures 37 therein, through whichwater may drain in case of unintentional spilling of water into the pan.

For the purpose of venting the combustion chamber, when a wash-boiler is on the stove a suitable number of spacing blocks 38 and 33 are secured to the tops of the top plates 1 and 2 of the frame,

similar spacing blocks

39 and 39 being secured upon the transverse top plates 3 and -lrespectively to directly support the bottom of the washboiler and aord channels beneath said bottom to induce circulation of heated air whereby to obtain high efficiency in operation of the gas-burners. The spacing blocks may be secured in place by means of rivets i10, or may be secured by welding if desired.

ln practical use the stove is easily carried by one person, even though not a strong woman, and is readily placed where desired, a gas-supplying hose or pipe being connected with the gas-cock, the latter to be opened when ready and the gas escaping from the burners immediately ignited. Atmospheric air becomes mixed with the gas in the single mixer and therefore the same quality of fuel gas is conducted to both of the burners. A wash-boiler is to be placed upon the spacing` blocks of theJ frame for boiling water for washing or other purposes. The position of the wash-boiler on the stove is indicated by broken lines in Fig. 3, it being designed that the heat shall induce upward currents of water adjacent to the longer sides of the wash-boiler, downward return currents occurring between the upcurrents, so that there shall be considerable velocity of current to assist in cleansing garments or fabrics which may be placed in the boiling water. The stove may be found useful for heating other vessels that can be suitably placed on the stove.
