Letters-Patent No. 104,266, dated June 14, 18.70.

IMPRovED WASHING AND COOKING-Bomen.

The Schedule referred to in these Letters Patent and ymaritim;l part of the same To all whom, it 'may concern:

Be it known that we, NATHAN-Tense and EMMA J. OASE, of Des Moines, in the county of Iolk and in the State of' Iowa, have invented certainJiew and useful Improvements in Combined YVashing and Cooking-Boiler, 8m.; and do hereby declare that the fol-y same, we willnow proceed to describe its construction i and operation, referring to the annexed drawing, in which- Figure lis a longitudinal vertical section of our boiler, and

Figure 2 is a plan view, on reduced dimensions, of the top of a stove, to show a new mode of instelling the middle plate therein. A W

A represents the boiler, provided in its bottom, at

one end only, with a projection, B, to enter into any common stove-hole, either ot' a common heating or cooking-stove, and, the balance ofthe bottom being flat, it may be set over an adjacent hole. Or, when such adjacent hole is needed for other* use, or the contents of the boiler get too hot, it may be readily'swung around and supportedA on alevel by a cord or chain, C, which passes through an eye or hook, D, or `over va pulley attached to a point above and directly over the center of the occupied stove-hole. The end of this cord or chain C is provided with aweight, H, as seen in lig. 2.

. The vessel A may be made after the manner of a common wash-boiler, a cast one being preferred, but

one made of sheet metal will answerA by being ma'de double, containing thereby an air-chamber, to prevent the condensation of the steam arising from the water in the bottom of the vessel, which condensation does not occur in using a cast vessel.

The boiler is further provided with a pivoted bail, E, which is thrown under the dat end of the boiler when tlie boiler is set oil' of the stove, and serves as legs to that end of the vessel. The bale is swung up when the vessel is sitting wholly upon the stove.

To further secure the holding ofthe boiler in a horizontal position, when a portion thereof extends beyond the stove, we provide a catch, G, on the projection B, which will bear against the vunder side of the plate between the stove-holes. This catch may be used alone for supportii'lg the boiler without the cord or chain above, but in that case it necessitates a somewhat diierent mode of attaching the said middle plate.

In tig. 2, A represents theplate usually laid loosely on between the stove-holes. This plate is provided in the center with a longitudinal recess, in which are placed pins a a. Under these pins, in the recess, are inserted other pins b b, which pass under the edge of the stove top, thus holding the plate c' so that the catch G on the boiler cannot lift it up.

. Into the boiler A is inserted an inside vessel or lining, I, of tin or other suitable4 material, fitting closely at the top, so that the wire in the Vtop edge of said,

lining will rest snugly on the top of the boiler A, thus allowing the same lid to be used either with or without the lining. Y

The bottom J of the inside vessel has two or more slots, so as to form a grate, and leaves a space :at one end of the vessel, between the end vand a partition,'

K, inserted therein, making au aperture or passage through which to replenish the water without condensing the steam or raising the main lid L. The lid L is at one end provided with a smaller hinged lid, M, directly over this passage, which serves as a safetyvalve in case of excess of steam.

The main lid L is composed of two plates or sheets about one-fourth of an inch apart, making a complete air-chamber to prevent condensation. The upper plate of the lid is provided with a very small hole, i, to permit the escape of expanded air.

Under the bottom or grate J ot` the inside vessel I is placed a slide, N, to eut ofi` the steam when it is desired to introduce anything or take anything-out of On the upper side of the bottom J are, slats c c, for a grate, It, to rest upon, and in the sides of the inside vessel I are offsets d, to place other grates or pans, as may be desired.

' The advantages ot' our machine are numerous. As a common boiler it can be used on any common heating-stove, or on a cooking-stove, without ever removing more than one stove-lid, therefore frequent-ly preventing the exit of a volume ot' smoke into the room. It can be turned in every direction to regulate the heat and give more room on the stove.

Everything for a meal can be cooked, including baking of bread, in thc same vessel, atthe same time,

'with half a common tire and halt' the water used in general cooking, and'keeping the same warm, with little trouble, for many hours. It possesses tillthe advantages ot' any steam-boiler, including the steaming of clot-hos, instead of boiling, to wash, which can be done with hard water, and vbut little. of it, two quarts of water being enough for any ordinary job of cooking or for steaming it full of clothes.

Having thus fully described our invention,

What we claim as new, and desire toffsecure by ALetters Patent, is-

l. The boiler A, constructed as described, with projection B at one end and pivoted bale E at the other, the projection B having a catch, G, substantially as and for the purposes herein set forth.

2. The stove-plate A, having a recess longitudinally across its center, and provided with pins a a and g b, substantially as and for the purposes hereinl set orth.

3. -The combination of the inside vessel-I with grate bottom J partition K, cut-o" N, and lever P, substantially as and for the purposes herein set forth.

i 4. The lid L, constructed as described, so as to form an air-chamber with passage la', and having a hinged lid, M, at one end, substantially as and for the purposes herein set forth.

.5. The oombinationof the boiler A, projection B, catch G, bale E, vessel I, partition K, grate bott-om J, cut-off N, lever P, double lid L, and hinged lid M, all constructed and arranged to operate substantially as and for the purposes herein set forth.

In testimony that we claim the foregoing, we have hereunto set our hands this 26th day of February, 1870. .f
