SPECIFICATION forming part of Letters Patent No. 450,974, dated April 21, 1891.

Application filed December 15,1890. Serial No. 874,717. No model.)

To all whom, it may concern.-

Be it known that I, HENRY O. NYE, of Syracuse, in the county of Onondaga, in the State of New York, have invented new and useful Improvements in Boiler-Cleaners,of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

The purpose of this invention is to eliminate the mineral substances from the feedwater entering the boiler and thus prevent incrustation of the latter; and to that end the invention consists, essentially, of one or more pans situated in the upper part of the interior of the boiler, and the feed-water pipe having its discharge end in one end of said pan or pans, as hereinafter more fully described, and specifically set forth in the claim.

In the annexed drawings, Figure 1 is a side View of a boiler provided with my invention, a portion of the boiler-shell being broken away to show the devices for eliminating the extraneous mineral substances from the feedwater. Fig. 2 is a transverse section on line 0: m, Fig. 1. Fig. 3 is a detached vertical longitudinal section of the pans, withthe feedwater pipe and blow-off pipe attached thereto,

and Fig. 4 is an enlarged longitudinal section illustrating the operation of the apparatus.

Similar letters of reference indicate corresponding parts.

B represents the boiler, and c c the flues through which the products of combustion pass.

P and P represent two open-topped pans,

which are arranged end to end in one continuous plane and communicate with each other at their junction. Said pans are situated in the upper part or steam-space of the boiler and extend lengthwise thereof.

In new boilers suitable supports for the pans may be applied to the boiler-shell, but for supporting the pans in boilers already in use I prefer to employ suitable metallic posts or trestle t 15, mounted on the top row of lines o c, and carrying upon their tops the aforesaid pans, as illustrated in Figs. 1 and 2 of the drawings. I incline the pans toward one end of the boiler and build across the interior of the pans at or near their junction a dam b, which extends part way the height of the pan,

and provided at the exterior thereof with the blow-off cock (I.

The pan P constitutes a steam-trap, which water-seals the discharge end of the feedpipe, so as to prevent back-pressure of steam in said pipe. The other pan P constitutes the precipitate collector, and the operation of said pans is as follows: In feeding water to the boiler while generating steam, the-water issuing from the feed-pipe agitates the water in the pan P, as represented in Fig. l of the drawings, and thereby prevents the impurities from precipitating in said pan. Neither is the infiowing water retained in said pan a sufficient length of time to heat said water to the temperature which separates the impuriblown out of the pans and through the blowoff pipe a by the pressure of the steam in the boiler.

I do not limit myself to any particular nu mber of pans to be used in a boiler, inasmuch as that depends on the length of the boiler, but in every case the pans are to be connected end to end and inclined toward one end of the boiler, as shown. It is also obvious that in a boiler of ordinary length a single pan may be made of sufficient length to an- The pans swer the purpose of myinvention.

are introduced into the boiler through the manhole thereof and are easily set upon their supports inside of the boiler and coupled together end to end. The form of the supports of the pans depends somewhat on the style of boiler to which the pans are to be applied.

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

The combination, with the boiler, of the precipitate-collecting, pan P and the steam-trap pan P, both open at the top, connected to-
