' IMPROVEMENT m WASH-BOILERS.

The. Schedule referred to in these Letters Patent and. making part of the same.

Natzttednd Objects of the Invention.

The subject of the invention is a removable inner boiler, which may preferably be employed in connec-' tion. with a' double cover,such as'isdescribed in my patent ofthe 18th of April, 1871. A i

My preseutimprovemeut consists injproviding a. re-

p movable innershe'llwith a deep perforated channel in i the bottom to prevent steam or suds being forced up, through the bottomof the said inner boiler, but at the I sametime. to allow a free passage of water downward 1 into the reservoir or water-space between the two X boilers. The said water isfforced upward between the inner and outer boilers, entering the inner boiler through perforations inthe sides thereof, or in the i doublecover if one is used, then percolating down through the clothesisoas to produce a perfect circuit, i of hot suds through the clothes, the sheet of which is l to cleanse them in -a very'short time' without friction or violence.

i The great adVantage of using a removable inner 1 shell or auxiliary boiler is that it admits of readily cleansing allthe partsof the apparatus.

Description of thelccompc'mflng Drawing.

Figure 1 is a longitudinal section of the entire apparatus. i

a Figure 2 is a perspectiive view of the removable inner shell or auxiliary boiler.

7 General Description. A represents tbebody of'a sheet-metal boiler, which may be made of common construction and of any approved shape. c

B 0 represent, respectively, the bottom and sides of the removableinner boiler.

{The sides are provided withapertures, c, of any necessary number, and 1- arranged as may be found most efficient. I prefer to employ a. large number near the upper margin, as represented. c is a flange projecting outwardly from the top of the inner boiler, and resting on' a flange or lugs, a, on the interior of the outer boiler,.so as to support the inner shell at a proper height within it.

.Drepreseuts a flanged lidcovering the outer boiler proper,-and furnished with an inner perforated plate, E, between which and the outer cover-is a water-passage, as is described inmy patent before referred to. 'F is' a sink or channelextending below the bottom B within the pit of the boiler proper, if such boiler be formed with a pit, andextending nearly tothe bottom thereof.

In the bottom of this channel is a number of perforations, f, through which the water passes downward;-

The operation of the apparatus will be clearly understood' from the foregoing description. p

The bottom B may be made separable from the sides, if desired, and supported .by'an inwardly-pro- .jecting flange. Without this separation, however, all the parts are readily accessible for cleansing when the inner shell. is removed from the boiler proper.

I have thus provided a washing apparatus as efiicient as any automatic boiler'in' use, while it is: of economical construction and perfectly easy to keep in order.

- Claims.

I'claim asmy invention 1. The combination of the bottom B, the sides 0, apertures c in upper part of sides, and the deep channel F extending longitudinally of the bottom, andw e m Z
