Leners Patent No. 113,712, dates April 11, 1871.

IMPRQVEMENT IN WASH-BOILERS.

`'.lhe Schedule .referredto in these Letters Patent and making part of the same.

To alt whom it 'may concern:

Be it known that we, WILLIAM A. WELLS, of St.Y Paul, in the county of Ramsey and State of Minnesota, and Linnenl l?. CONVERSE, of the city and county of Milwaukee and State of Wisconsin, have invented certain Improvements in Wash-Boiiers and we do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the annexed drawing making part of this specifica` tion, in which- Figure l is 'a vertical longitudinal section of our improved wash-boiler.

' Figure 2 is a vert-ical transverse section thereof.

' Figure V3 is a horizontal section.

The same letters Aare used in all the gnres in the designation oi" identical parts.

rlhis invention relates to that class of washboilers which are constructed with circulating dues or passages for conducting the heated water and steam from the bottom of the boilerto the top to be forced downward through the clothes to be cleansed; and

Our improvement consists in .the construction of the clothes-supporting grate, and its combination with the boiler, and also in4 the employment of a siphonic faucet for' drawing the water from the boiler.

To enable those skilled in theart to make and use our invention, we will proceed to describe its construction' and operation.

The shell A'of the boiler is diminished vin size at the bottom in the ordinary manner, to form the part A', which enters the stove-hole when it is used.

Upon the shoulder thus formed in the interior of the boiler the clothes-supportin g grate or rack B rests, it being of such size that it maybe readily inserted and removed.

This grate consists of a band of tin of the proper width, and suitably strengthened around the edges by wires, which is provided with a series of perforations, I), along the upper edge, for the purpose of receiving a. strong cord, B', to he laced or woven in the manner clearly shown in iig. 3, so as to form a web or grating 'upon which the clothes may rest to be held above the bottom of thc boiler.

As the cord or cords forming this web must be drawn 'very taut the hand of tin is provided with braces b1 between its sides, to prevent its collapsing ou thus drawing the cords.

A vertical passage, O, is formed upon each of the parallel sides of the boiler by a plate, O', soldered at its ends to the rounded ends thereof, and on top by a flange to the side.

The passage is open at the lower end, which extends to just below the upper edge of the supportinggrate, and near the upper end it communicates with the interior of the boiler by a series of port-s, c o, the which in one plate C should be diagonally opposite to those in the opposite plate C', so that the jets of hot water and steam may not meet on issuing therefrom.

Perforations b2 in the band of the supporting-grate permit of the passage of the heated water and steam from below the clothes up into the passage O, from .which such water and steam issues at the top upon the top of the clothes, in passing through which the dirt is carried down to the bottom.

The lid D is secured by passing one end of it under a fixed cross-band, secured to the shell of the boiler, and couning its other end by a hinged catch, d', as shown clearly in iig. 1.

A vertical pipe, E, is arranged iu one end of the boiler, through which 'cold water can be conducted to the bottom of the boiler when in operation without passing it through the clothes.

F is the faucet used to draw the dirty water from the boiler in order that clear water may take its place in completing the cleansing process. This faucet is a siphou with its short leg which enters the boiler extending down to Very -near the bottom thereof', so that it can draw ofi` all the water without tilting the boiler.

Vhat we claim as our invention, and desire to securev by Letters Patent, is-

In combination with a wash-boiler constructed substantially as herein described, the removable clothessupporting rack, composed of metallic rim B and intel-laced cords B', and the siphonic faucet F, as and for the purposes set ibi-th.

' In testimony of our inventionwe have hereto set our hands.
