IMPROVEMENT IN WASH-BOILER ATTACHMENTS.

Specification forming part of Letters Patent No. 135,569, dated February 4, 1873.

To all whom it may concern:

Be it known that I, MATHIAS MARTIN, of Baltimore, in the county of Baltimore and State of Maryland, have invented certain new and useful Improvements in Wash-Boiler Attachments; and I do hereby declare that the following is a full, clear, and exact description thereof, that will enable others skilled in the art to which it appertains to make and. use the same, reference being had to the accom panying drawing and to the letters of reference marked thereon, which form a part of this specification.

Figure l is a. perspective View of my i mproved attachment to wash-boilers; and Fig. 2 is a transverse "ertical section in the line .70 m, Fig. l.

Similar letters of reference in the accompanying drawing indicate the same parts.

This invention belongs to that class of washboilers in which, when water is supplied and heat applied, the water is made to rise in a pipe located within the boiler, and pour out of its top, falling on the fabrics placed in the boilerand cleansingtheln thoroughly from dirt. The invention has for its object to improve the construction ofa boiler of this kind in such a manner as to prevent the steam that is generated within the box from which springs the pipe aforesaid from flowing backward under the box into the boiler instead of ascending with the water through the pipe to assist in the cleansingprocess; to this end the invention consists in the combination with said box of a diaphragm placed within the box in front of the perforations in the same, and at asuitable distance therefrom,to permit the water to tlow freely into the box, which diaphragm, in conjunction with the water, prevents the steam generated within the box from escaping therefrom through said perforations; all which I will now proceed to describe.

In the drawing, A is the box aforesaid, the

same being intended to be placed on the bot-- tom of an ordinary wash-boiler, and having a pipe, A, springing from its top near one end, and perforations a in its sides and other end for the entrance of water. B is the diaphragm aforesaid, the same being placed parallel to the sides and end of the box, at a suflicient distance within the same not to obstruct the free flow of water. The diaphragm is secured at its upper edge to a flange, B, extending inward from the sides and end of thebox A, just above the perforations a, and having ends 1/ turned down past the ends ot'the diaphragm B.

\Vhen the boiler is supplied with sufficient water to cover the box A and heat is applied thereto, the steam generated within the box in the vicinity of the perforations a would, unless in some way prevented, have a tend ency to escape through them, as they would be in the lines of least resistance; but itis desirable that all thesteam generated within the box should pass with the water up the pipe A in order to assist in cleansing the fabrics. Accordingly, the function of the diaphragm B is to prevent the escape of steam through the pertorations a, and turn it all in the direction of the pipe A.

The construction above described can also be applied to cotfee-boilers or other similar vessels.

Having thus described my invention, what I claim is- The box A, having perforations a, and combined with the diaphragm B and tube A, substantially in the manner and for the purpose described.

In testimony that I claim the foregoing I have hereunto set my hand this 30th day of October, 1872. V
