This eneirclioffrire l is designed to furnish the f for supper-Ling the dish or r' el l, wir h in iziie present instance is the vessel tha; enters ihr: lower portion of the boiler, und muy come in dire/e5 cominci. with the wuer hcrein cof. einen. wir second dish or vessel, C, is supported upon the top of the vessel B, its contents being protected by a. cover or lid, I), as shown in Fig. 2. It' the circumstances. require it, another dish or Vessei--sneh as the performed dish .li-may be employed, in which cose the seid dish would 'ind u sont upon the upper edge of the boiler, und between said boiier :rnd e; suitable cover. In the use oi' the cooker either one or more of these dishes may he employed, and thedishes being cach provided with wire eyes e, are readily removed i'roni the interior of the boiler hy o. suituhlebnil (uol: shown) vwith which the eyes c are engaged.

The cover .Fof the cooker is of peculiar format-ion, und being oi' o. diameter somewhat larger than the diameter o1 the boiierbis designed no pass over rue upper portion of said boiler, with iis lower edge resting upon she enei reihig-hongo b, therein formed. ln the upper portion of the cover is n diaphragm or plete, (i, from which extends upwardly o. tube, H, through which iuhestcnmpusscs as it; lenves the nluic G- und the iop of the cover, iinds un oublet through un annular series of perforations,

y, formed near the outer circumference of the diaphragm G, ns shown in Figa 2.

It will be observed the diaphragm is depressed nenr the annuler series of peri'orations, thereby forming a seni; for the upper edge oi' the hoilc.i,nnd permitting the steam, :is it escapes through the perforations, to be discharged in the splice between the outside of bhe boiler and the inside of the oever.

From the foregoing description il; is munifcsithat water being poured into the trough A oi' the boiler passes through the holes p in thc lpluto l und enters the interior of said.` boiler. The slieeni es it is generated passes upward through the upper open cud of tho conical plnte,nnd thence uroundthe dishes into the cover F.' The ascending stormy, as iii passes through the inbe H, impinges upon the under surface of the top of the cover and heats suidsurface. The steam, nicer entering the chamber or stennrsp '.rcobetlween tl i o diaphragm G und top of cover, is deiieeted downward and passes through the annuler :series ofperi'ora.- tions g, und thence into the space between the boiler und cover, where, in its further descent, ib moois currents ol' cold nir entering u series whenee it passes through orher openings, m,Y in the boiler sind is returned to the inside oi the some. By this arrangement. n eont-innons circulation of steam is maintained during the entire period the cooker is in use, and by di rooting the body oi steam. against the ninler side oi" he top of the cover it. is nienii'est, if :L coffee-pot or other vessel he placed upon the Cover, the steam will keep the contents ol' soin vessel ai; n boiling-heno The boiler A is provided vwith n ihneet., L, by'meons of whieh hoi; water non he drawn from theinterior of the boiler forsneh lomos tie purposes moy be desired.
