UNITED STATES PATENT EEICE.,

GEORGE MICHAEL BRAUNINGEE, OF JANESVILLE, VISCONSIN.

BILER-WATER PURIFIER.

SPECIFICATION forming part Of Letters :Patent N0. 294,754, dated March 11, 1884. A Application ined Aprno, Issa. (No moda.)

coupling-rod is inserted, and operates as a binder to hold the said pans in their proper place, and other things more fully explained in another connection.

The object of my improvement is to provide a device for separating and secreting the lime and sediment from the water to be used in the boiler to which my device is applied, whereby such lime and sediment are prevented from being precipitated upon the inner surface of the boiler. I attain these objects by the mechanism-illustrated in the accompanying drawings, in which- Figure l is a vertical section of the entire apparatus. Fig. 2 is a top view of one of the open pans separated from the others, which separation is easily accomplished after taking oft' the cover. Fig. 3 is a perspective view of the said shaft or coupling-rod. Fig. 4 is a vertical section of Vmy device in the boiler, showing among other things the holes 4in the .bottom of the several pans communicating between the pans, arranged alternately on the respective sides of the connecting-shaft.

Similar letters refer to similar parts throughout the several views.

The jacket d constitutes the outer framework-of the apparatus, and operates as a shield to the inner work. The said tubular shaft o is used as a blow-off pipe. The upper end thereof is closed with a screw-cap, e, which cap retains the top plate, f. The lower end of the said shaft c is furnished with an elbowcoupling, s, to which may be added other pieces of pipe of any length desired, and arranged at any particular angle, so as to connect with the outsidevof the boiler, and when thus arranged may be used to blow oft' the said purifier. The water is forced into the purifier, in the ordinary way, through the pipe i in the top plate, f, and in its course down through the several pans t t it changes from right to left, and vice versa, according to the l arrangement of the holes 7c 7c in the bottom'of the pans. The bottom pan is perforated with holes p in the rim thereof, through which the puriiied water passes into the boiler. The said shaft c is also perforated or pierced with holes from the chamber of each pan, so that when the outer end of the shaft c below the elbow s is opened to the outer air the steam will rush'into the pans through the openings p, and up through the openings lc into the several pans, and out through the shaft c, carrying with it the water and sediment vin the several pans. It is obvious, therefore, that the boiler is protected from the damaging effect of impure water, as it is thoroughly purified in passing over a heated surface of some twelve or fifteen feet.

The object of the partition n in each pan is to cause the water to pass over a larger bottom surface.

It is obvious that I am enabled to blow off and renovate this apparatus from time to time as desired without disturbing the water in the boiler or stopping the engine. Also, it

V`is obvious that, my apparatus being made in detachable sections, I am enabled to remove them one at a time from the boiler through the man-hole for cleaning or repairing whenever required.

I am aware that prior to my invention boilerwater purifiers have been used with shelves and pans'and blow-off pipes. I therefore do not claim such a combination, broadly; but

Vhat Ido claim as my invention, and desire to secure by Letters Patent, is

l. The combination, in a boiler-water puri- 'eig of a series of pans forming chambers, and

a central column or shaft, c, pierced with holes m m, communicating with each chamber, all arrangedto operate in the manner and for the purpose herein described.

2. The combination of the inclosing-case d, the series of pans c a, provided with the partition n and holes k lc, and central tubular shaft, c, provided with cap e and the holes m min each succeeding chamber, said partition@ being adapted -to cause the water to iiow over the entire surface of the pans' while iiowing from one to the other, all substantially as and for the purpose specified.
