WASH-BOILER.

(No model.)

To all whom it may concern:

Be it known that I, MARTIN F. D. C. DANN- MEYER, of the city and county of San Francisco, State of California, have invented an Improvement in WVash-Boilers; and I hereby declare the following to be a full, clear, and eXact description of the sane.

My nvention relates to certain improvements in wash boilers or devices in which clothes are cleansed by the operation of a continuous stream of hot water; and it consists of an outer inclosing case or boiler and an interor diaphragm formed with double walls and top, with a filling of non-conducting material, this diaphragm resting upon the bottom of the outside boiler, and having a space beneath it and passages by which the water may pass from above into this space, with directingplates and upwardly-extending pipes whereby the circulation is maintained, all of which will.

be more fully explained by reference to the accompanying drawings, in which- Figure l is a view of one form of my device. Fig. 2 is a perspective view. Fig. 3 shows the arrangement for two water pipes or passages.

A is an exterior boiler or shell, of any suitable or desired size, Which is fitted to receive water and clothing and to rest upon the stove, or to have an independent heater, as may be best suited for the work to be done.

B is a device which is fitted to rest upon the bottom of the boiler. The top and walls of this device are made double,and afilling ofnon-conducting material is placed in the spaces thus formed, so that little or no heat passes directly through the top and walls of this device. It is made alittlesmaller in every direction than the interor diameter of the boiler, and the sides eX- tend downward, so that a space is left between the bottom of the boiler and the top of this device. Either the sides, as shown in Fig. 1, or the ends, as shown in Fig. 2, are continued down, so as to rest upon the bottom of the boiler, while the intermediate portion forms spaces, as shown at O, through which the water coming down around the sides ofthis device may pass freely into the spaces beneath it.

D D are horizontal plates, which extend a short distance inward toward the center from the ends in Fig. 1, or from the sides, as in Fig.

2, and these serve to give direction to the inflowing current of water, so that it passes directly towardthe center over the bottom of the boiler. Through the center or ends of the top, large openings are made, and pipes E eX- tend upward to a point near the top kof the boiler. In Fig. 1 I have shown a single pipe which extends upward from the center, and it has a deflecting-plate, F, supported above its top, so that the water passing out through the top of the pipe strikes this deflector, and is by it thrown outward in every direction to- Ward the sides of the boiler. In Fig. 2 I have shown two of these pipes, the upper ends of which may be curved or have defiectors for a similar purpose. The ebullition of the water beneath the device B causes the hotter portion of the water and steam to pass upward through the pipes E and be discharged in a Constant stream over the top of the clothes. This produces a certain vacuum in this chamber below, and the result is that the water is forced downward through the clothes by atmospheric pressure, passing around the sides, and thence beneath through the open spaces O. In some cases doors or flaps H are hinged so as to fall down over the spaces O and close them against any outward flow of water from the chamber beneath. The hinges are so arranged that the doors will easily open inwardly to admit the water. The horizontal plates D just above these spaces serve to direct this current along the bottom of the boiler and prevent its intermingling or interfering with the water which is in the upper part of the chamber, thus causing a smooth and rapid flow of water all the time. By reason of the non-conducting material forming the top and sides of this device little or no heat passes directly up into the body of water which fills the boiler above this chamber, and consequently the heat is confined in the chamber of the device B, thus causing a powerful current to be discharged upward through the .pipes, and an equally strong downward current through the clothes, which are thus very effectually cleaned.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a wash-boiler, a removable Chamber IOO fitted to the lower part of the boiler, and having double walls and sides, With a filling'of non 'CondnCting material, substantially as herein described.

2. In a Wash-boiler, a Chamber having its top and Walls made non-conducting, with the sides or ends extending downward so as to rest upon the bottom of the boiler, with intermediate spaces opening from the exterior of the Chamber beneath, in combination With verti- Cal pipes or passages extending upward from said Chamber to the top of the boiler, substantially as `herein described,

3. A Wash-boiler having a Chamber of smaller dimensions fitted to rest upon the bottom so as to form an inClosed space beneath, the walls and top of said Chamber being filled'with a' material which is a noncond1etor of heat, and pipes OP Passages extending upward from this Said Chamber to the top of the boiler, in combination with defleetere by which the water is distributed from the. Heper end of the pipes substantially as herein deseribed.. i

4,- A. wash-beile? .having within it. a ehamber of smaller dianeter, the sides orI ends of 25 which rest upon the bottom of the boiler so as to form an inclosed space beneath, thev top and sides being madel non-Conducting, as shown, and pipes or passages extending upward from the inclosed Chamber to the top of the boiler, in combination With horizontal guides or plates extending inwardly above the passages Which lead to the Chamber, substantially as he'ein described.

5. A was'hboi1er having within it a Chamber of smaller diameter, the sides or ends of whiCh rest upon the bottom of the boiler so as to form an'inClosed space beneath, and upwardly-extending pipes or passages from said Chamber, in combination with the inwardly- 'opening doors or va'lves H, substantially as 'herein de'sCribed.

In Witness whereof I have herennto set myv hand.
