SPECIFICATION forming part of Letters Patent No. 352,235, dated November 9, 1886.

Application filed July 31, 1886. Serial No. 209,666. (No model.)

To all whom, tmc/,y concern..-

Beit known that we, HENRY V. FARIEs, a citizen of the United States, residing at Atchi` son, in the county o'fAtchison, State of Kansas, and CHARLES D. WILcoX, a citizen of the United States, residing at Indianapolis, inthe county of Marion and State of Indiana, have invented a new and useful Improvement in Boiler-Cleaners, of which the following is a full, clear, and exact description, such as will enable any one skilled in the art to which it appertains to make and use the same.

scribed, and

Our invention relates to that class of boilercleaners in which the impurities in the water are skimmed from the surface and conducted into a settling-drum, from which they may be blown out, the cleaned water being returned to the boiler. v 'p Theobject of our invention is to accomplish the removalof the impurities in'a more effectual and thorough manner than heretofore; and tothis end our invention consists in an improved skimming device, as hereinafter departicularly pointed out in the claims. A

In the drawings accompanying this specification, and forming a part thereof,V and in which like letters refer to like parts inboth the iigures, Figure 1 is a longitudinal section of our invention applied to a boiler. Fig. 2 isa crosssection of the boiler on the line x 1 Fig. 1.

A is a boiler, having the ordinary iiues, B B. Just above the dues, and submerged below the level of the water, is a pipe, C, closed at each end and extending-nearly across the boiler. Projecting fromfthis pipe are several small tubes, D D, which are preferably inclined, as shown. Each of these tubes is closed at its upper end, and is perforated with a number of small holes, d d, distributed over its entire surface. The tubes are of such a length as to project above the surface of the water into the steam-space. They may be arranged in one, two, or more rows,'and may be disposed opposite to each other, or staggering, as deemed most desirable, the object being to enable the skimming to be done over as wide a range as possible, both vertically and laterally. The tubes D D extend upward some little distance from the pipe C, in order that at the differing heights of water in the boiler they may always ai'ord an outlet for'the impurities floating on the surface. An eductionpipe, E, leads from the submerged'pipe O up through the top of the boiler to the drum F, and is provided with a valve, e. An ejectorpipe, G, whose upper end, g, is located well above the water-level in the boiler, so as to communicate constantly with the steam-space, enters the pipe C and terminates just below the lower end of the eduction-pipe E. From the upper part of the drum F the return-pipe H,'controlled by the valve h, runs down into and nearly to the bottom of the boiler. The blow-off pipe I, provided with a valve, t', connects with the lower part of the drum F.

The operation of our apparatus is as follows: When the valve c is opened, the steam enters the upper perforations in the tubes D D, and produces an upward iiow of steam and water through the eduction-pipe E. This is greatly accelerated by the dry steam, which enters the ejector-pipe G at g and discharges into the lower end of the eduction-pipe E, carrying up through said pipe the water and the impurities which have entered pipe C through the perforations d d in the tubes D D, and at the same time sucking in through said perforations a further supply of water and the impurities which are in the vicinity of the tubes, and creating a current toward the tubes from all parts of the boiler. The impurities settle in the drum F, from which they can be blown out through the pipe I, the cleaned water beingY returned to the boiler through the pipe H. This operation removes from the boiler all foreign andinjurious matter, our arrangement of the perforated tubes D D, together with the ejector-pipe G, giving better results than any other device of which we are aware. f

Having thus described our invention, what we claim, and desire to secure by Letters Patent, is-

1.V In a boiler-cleaner, the skimming device herein shown and described, consisting of the pipe O and the upwardly-inclined perforated tubes D D, substantially as and Vfor the purpose set forth.

2. In a boiler-cleaner, the skimming device herein shown and described, consisting of the ppeO, the upwardly-inclined perforated tubes D D, and the ejector-pipe G, substantially as and for the purpose set forth.

3. In aboiler-eleaner, the colnbination,with a boiler, of a submerged pipe, C, anda series of upwardly-inclined perforated tubes, D D, arranged to project above the surface of the Water, substantially as and for the purpose set forth.

4. In aboiler-cleaner, the combinatioinwith a boiler, of a submerged pipe, C, closed at each end, a series of upwardly-inclined perforated tubes, D D, closed at their outer ends, an eduction-pipe, E, and an ejector-pipe, G, communicating with the steam-space and -terminating just below the lower end of the eduction-pipe, substantially as and for the purpose set fort-h.
