N. D. GOFF WASHBOILER Filed Dec. 8, 1927 Patented Dec. 10, 1929 NARA D. GOFF, or cnm'ronglowa- WASHBOILER Application filed December The purpose of the present invention is to produce a washboiler primarily intended for domestic use, of increased utility, efficiency and economy. I have found that if the s ur- .face exposed to the heat be increased the con-' tents of the boiler will be brought more quickly to the boiling point and the fuel be more efliciently made use of.

Forms my invention take are illustrated in the accompanying drawings in which Figure 1 is a transverse vertical section through a washboiler embodying my invention; Fig. 2

is a transverse horizontal section through a washboiler; Fig. 3 is a top plan view of the cover; and Fig. 4 is a transverse vertical section of a washboiler embodying my invention in another form.

The washboiler comprises the usual bottom piece 1 which is joined in a suitable manner -to the wall member 2. While the form or shape of the washboiler is not material to my invention I have shown the usual or typical form which is somewhat oval in plan having straight sides and more or less circular ends. In this construction there is a single side wall member which runs around the entire washboiler. It is this side member which is marked 2 in the drawings and it cooperates with the bottom member to form the recepta- 'cle into which water or other material to be heated is placed and into which the clothing to be boiled may be placed.

The structure so far described is of the usual well known ordinary type. In order to incorporate my invention in full I make certain changes therein or additions thereto.

The bottom 1 of the boiler is perforated and in the perforations are insertedand fastened upwardly extending tubes 3. These tubes 3 may be separated somewhat from the sides 2 of the boiler but I prefer for practical reasonsto have the tubes 3 run upwardly in contact with the side wall 2, The tubes and the side wall may thus be fastened together and so lend greater rigidity to the structure as a whole. In the usual washboiler prior tomy invention the heat struck only upon the bottom of the boiler and was conducted throughout the contents of the boiler by internal circulation of the fluid only.

I

It will 'be-v readily seen thatfif the bottom of the boiler is smooth andnot provided with theLflangeA theheat on strikingthe bottom willdeflectan ddissipate. my arrangement-.however the heat is restrained by the dependingfiange 4 whichacts as a baffle wall anddefleQtS the heatupwardly through the tubes 3. thus. affording increased application of the heat and more efficient use thereof. It will be understood; of course, that the connection between the bottom. 1 and the side wallf2willbe made water tight in anyusual or suitable manner and likewisethe jointsbe tween the tubes 3Iandthebottom 1 will be madewatertight inany usual and. suitable manner. I I g y The whole structure may be made of metal andJfor greateriefiiciencyymetals of thehigh- U est heat conductivity may be employed. The tubes 3fmay, extend to the top of the side wall 2 but when thecover is to'be used with the boilerl prefer tofextcnd the tubes 3 higher than or :above theside wall 2 and to provide the:cover .5 with perforations 6 to receive and pass over T the upward extensions of tubes 3. It willbeobserved that in order to allow free passage;offthe heat the tubes are open and. unobstructed. at both ends.

While thetubesv 3 may be fastened. to the I sidewall 2-by;welding or in any other suit-- able manner I have shown them as soldered to the sidewall -2..in Fig. 2. In Fig. 4 1 have shown anoption'al form in which the cover 5 need not be perforated. In this arrangement I have shown theztubes 3 rising from the bottom. l and toward their upp'erends curved outwardl .and passing through perforations in tlie sic ewall 2., This arrangement allows open endedtubes Vertically disposed and ex a free passage of the heat which by the baflle or flange 4 is deflected upward through the tubes 3? which extend through the contents of the boiler and then laterally through the open ends of the tubes in the perforations in the side wall 2.

When the boiler is placed on the ordinary heating stove with a flat surfaceon which the boiler rests,'a series of round holes or perforations can be placed in the flange or bafile, the purpose of the openings being to insure a free passage of hot air currents from-both underneath the boiler and outside thereof. This construction will insure a free passage of hot air currents that are radiated from,

possibility of any vacuum forming und'erneath the boiler.

Changes may be made from the, details here shown embodying my invention. I claim as my invention: '1. In a washboiler, a bottom, a side band,

tending from the bottom upward adjacent to the side band and above the top of the side band, and a removable cover perforated to fit over the upper ends of the tubes-and close the washboiler.

2. A washboiler comprising a perforated bottom, a side wall extending upward from of the tubes passing through the perforations in the cover.

5. In a washboiler, a bottom, a side band extending below the bottom and forming a flange and open ended tubes vertically disposed and extending from the bottom upward in contact with the side band.

'3. A washboiler comprising a perforated bottom, a side wall extending upward from the'bottom, open ended tubes in the perforations extending upward from the bottom within the boiler and adjacent to the side wall and connected thereto, and an extension of the side wall below the bottom and adjacent the lower open ends of the tubes and acting as a baflie to deflect heat upward,
