BOILER-CLEANER.
SPECIFICATION forming part of Letters Patent 1\l'o. 406,358, dated July 2, 1889 Application filed July 2'7, 1888. Serial No. 281,215. (No model.)
To all whom it may concern.-
Be it known that I, FRIEDERICK LINDRUM, a citizen of Prussia, residing at Chicago, in the county of Cook and State of Illinois, have invented new and useful Improvements in Boiler-Cleaners, of which the following is a specification.
My invention relates to improvements in boiler-cleaners for' removing the impurities in the nature of scum in steam-generating boilers.
It has for its object the efficient and expeditious removal of said impurities; and it consists in the construction hereinafter described and shown, and embraced in the claim.
The accompanying drawings show my improvements as embodied in ahorizontal tubular boiler in the form I now prefer; but they might, however, be applied to other forms of boilers and changed in some respects that would be obvious to a skilled mechanic without departing from the spirit of my invention.
Figure 1 is a vertical longitudinal section of a tubular boiler and its setting and the cleaner within the boiler. Fig. 2 is a vertical transverse section through the boiler and cleaner.
Like letters of reference refer to like parts throughout the specification and drawings.
The boiler-shell A may be of any desired form, but is preferably shown as of the Ordinary horizontal pattern with the usual steamdome a and the man-hole plate a.
Suspended within the boiler by any suitable means at a convenient height above the bottom is a scum-collector, which consists of a tight cylindrical vessel B, from the top of which a series of small tubes b extend to a point just below the normal water-line of the boiler. These tubes have flaring or bellshaped tops, and they communicate with the interior of the collector l3.
In ordinary practice the violent commotion of the water within the boiler brings to its surface a large quantity of-impurities in the shape of scum, which, being unable to pass off with the steam, gradually collects until it forms a mass of greater specific gravity than water, when it will sink to the bottom or gather on the sides of the boiler, to which it will adhere in the form of a scale, that is' very detrimental to the boiler and difficult to remove, as is well understood by those conversant with boilers. Vith my invention, however, the surface of the Water immediately above the bell-shaped mouths of the collecting-tubes will be in a comparatively quiescent state, and the scum, which at other points is kept afloat by the violent ebullition of the water,will,when it has floated into any of the quiet zones, sink into the tube-mouths and be automatically skimmed off the surface of the water and deposited in the collector, from which it may be removed, as will be explained farther on. There is no danger of the scum incrusting or scaling in the collector, as the latter and its connections are not subjected to the direct action of the fire at any point.
A large aperture is formed in the front head A of the boiler, from which a projecting neck or tube 0 extends to a pointin front of the boiler-setting, where it is closed by a plate 0, securely bolted to the annular flange c at theextremity of the neck.
Ablow-off pipe B from the front head of the collector near its bottom extends through this neck and the plate 0, outside of which it is provided with a valve 1), by means of which the discharge from the collector may be regulated as desired. This pipe is screwthreaded near its outer end, and is provided with check-nuts and soft Washers on each side of the plate 0, to form a secure and tight joint. From the valve 1) the blow-off pipe may lead to any desired place, as to a drain or sewer, or, as shown in the drawings, back into the ash-pit G under the grate-bars, where the water would serve to dampen down the ashes.
Having thus described my invention, what I claim as new and useful, and desire to secure by Letters Patent, is
The combination of the boiler, the tubular projection from its front head extending through the front wall of the setting, the
collectin g-vessel and its skimming-tubes Within the boiler, and the blow-off pipe provided with a valve outside-of the tubular projection leading from the collector through the tubular proj eetion, whereby the eollectorancl its connections are protected from the (lirect action of the heat, substantially as and for the purpose hereinbefore set forth.
In testimony whereof I affix my signature in the presence of two witnesses.
FRIEDERICK LINDRUM.
