. IMPROVEMENT IN WASH-BOILERS.

m y The Schedule referred to n these Letters Patent and making part of the same To all whom it may concern Be it knownV that I, TrioMAs EvANs, of the city of Newark, in the county of Essex, and State of New new and useful Improvement in Wash-Boilers; and I herebydeclare that the following is a full and exact description thereof, refer- `ence being had to the accompanying drawings, in which Y Figure 1 is a side elevation.

Figure 2 is a plan view.

Figure 3, a vertical transverse section.

Like letters of reference designate corresponding parts.

My invention relates to that class of boilers known and consists in the arrangement of the felevating-pipes on the outside` of the boiler, as, vhereinafter described, and in constructing the removable bottoni with one or more ofthe water'- ways, which form a connection with the outside pipes, hingedv for the purpose hereinafter stated, and also in providing the cover with a rack for keeping the clothes depressed while boiling, to prevent their obstructing the waterpassagesl As representedin the drawings- A is an ordinary wash-boiler, having` two main pipes, B, arranged upon either side, their projection being wholly upon the exterior of the vessel.

Passages c'c connect these pipes with the interior, and each pipe is separated into two divergent branches, d d, which pass through the sides of the boiler, near the top thereof.

A removable perforated bottom, C, divides the interior ofthe boiler,form ing a water-chamber at its base.

In this bottom, elevations are formed, corresponding in position with the apertures c c, so that said bottom may be placed. below these orifices, and yet a watercourse be preserved between the lower chamber and pipes B B.

This constructionl enables the perforated bottom to@ be placed as low as is practicable, in order to utilize the greatest amount of space inthe boiler.

lhe mouths, or dischai'ge-orices e e e eof the pipes d d, are preferably so Iarranged as to discharge their respective jets of water in diierent directions, and

thereby more fully theirV operation. y

The paramount object which is accomplished by so arranging the pipes upon the outer sides of the boiler, is to prevent their occupying any of the-interior or serviceable space4 of the boiler, while the bifurcated form enables their points of dischargeto be more advantageously located to act uniformly upon the clothes in all parts of the vessel. At the same time, this construction greatly strengthens the sides of the boiler, by stiieningand bracing them at their weakest points.

The pipes being, therefore, inseparably attached to the boiler, the only part which is necessarily removable, is the perforated bottom G. v

To facilitate the removal and insertion of this, either one of the raised portions ff' may be hinged at t', so as to be thrown back, as shown in red lines in tig. 3.

By this means the bottom is removablerwith ease,

by simply raising it by the ring g. The beneficial action of boilers of this class is liable to be impaired by the clothes rising and obstructing the mouths ofthe elevating-pipes el d, thereby checking the current which is forced upward by the action of the steam, and overflowing the boiler. To prevent this, I att-ach to the cover H the bars or rack k k, projecting downward from' its under side, which prevents the rising of the clothes high enough to obstruct the jets.

What I claim asmyiuvention, and desire to secure by Letters Patent, is-

The combination and arrangement of the removable bottom 0,' with elevations, Y the hinged passage c f, the external pipes B, with diverging branches d (l, and therack k, tbe passage communicating with the main pipes, and the branches arranged to discharge in opposite directions, when the parts are constructed and 'adapted to operate as described.

In witness whereof, I have hereunto signed my name, in the presence of two'snbscribing witnesses.

THOS. EVANS.
