PREVENTING SCALE- lN STEAM-BOILERS.
SPECIFICATION forming part of Letters Patent No. 554,530, dated February 11, 1896.
Application filed February 28, 1895. Serial No. 540,095. (No model.)
To all whom it may concern.-
Be it known that I, BERNARD McOABE, of Boston, in the county of Suffolk and State of Massachusetts,have invented certain new and useful Improvements in Preventing Scale in Steam-Boilers, of which the following is a full, clear, and exact description.
This invention has for its object the prevention of scales in steam-boilers, and the invention consists, in a steam-boiler, of the combination, with its water-supply pipe within the boiler, of a receptacle or chamber constructed and arranged for use, all substantially as hereinafter fully described, reference being had to the accompanying sheets of drawings, in which Figure 1 represents in side view a steamboiler broken out in part, showing this invention applied thereto. Fig. 2 is a longitudinal section of the present apparatus with the water-supply pipe in longitudinal section and partially broken out. Fig. 3 is a detail longitudinal section of the apparatus at one end with the water-supply pipe removed. Fig. 4 is a cross-section on line 4 4:, Fig. 2.
In the drawings, A represents a steamboiler; B, the water-supply pipe, which enters the boiler on its upper side at C, and extends downward therein a short distance, and thence in a horizontal line, as at D, all substantially as usual in stearn-boilers and needing no more particular description herein except as to the present invention. This horizontal portion D has in its two sides longitudinal slits or openings G, as shown, through which the water passes from the pipe B to supply the boiler. II is a shell or casing having a chamber J, which is closed, as at K, at its two ends, and has its upper side open, as at L, from one closed end to the other, as shown. This shell or casing II has an opening M through one of its ends, N, through which passes the portion D of the water-supply pipe, extending nearly to the other end, as shown, and the shell or casing is supported in the boiler independent of the water-supply pipe by cords or chains P secured thereto in any suitable manner, and fastened to the stayrods Q of the boiler, as shown in Fig. 1.
On the inner sides of the chamber, each side thereof, are secured two horizontal series or rows S T of small or short plates U,
each secured by rivets V, which plates proj ect horizontally or substantially horizontally into the chamber, as shown in Fig. 4c, the upper row or series, S, being arranged to be over the opening or spaces 7 between the several plates of the lower series, as shown in Figs. 2 and 3.
The water from the pipe B passes out through the longitudinal slits Ginto the cham-. ber of the shell and strikes with more or less force against the sides of the chamber and against the several plates U before it flows over the top edges R into the boiler, and in such movement it is decidedly stirred, agitated or churned more or less, so that the foreign matter, which is generally deposited in the form of scales on the inner surfaces of the boiler, is here stopped and deposited and left or adheres to the sides of the chamber or plates in such quantity that in practical operation or use of this invention the scales are prevented from passing to the boiler, while the inside of the shell or casing and the plates receive and are covered with the scales.
The scales on the shell can be easily removed by detaching the shell or casing from the boiler and water-supply pipe through the usual manhole of the boiler, and taking it from the boiler, and having cleansed it, it can be easily placed in position as before. This chamber or receptacle is preferably made of copper, although it can be made of any suitable metal, preferably a non-corrosive one.
In use practically for a boiler of ordinary size the chamber will be about three feet in length and eight'inches in diameter, having its opening L, as shown, and it is preferable to have the shell of tubular form, although it can be of any form in cross-section, square, elliptical or otherwise, and it can be supported in any suitable manner.
The water-supply pipe can have any number of outlets and of any form desired, but the slit openings, as shown, are satisfactory; also it can pass freely through the end N or closely, as desired. A more or less number of these platesU can be used in the chamber, and also they can be secured in any suitable manner.
Having thus described my invention, What I claim is- In combination, a steam-boiler, a receptacle or shell supported in the boiler-chamber having an opening in its upper side, longitudinal rows of separate plates projecting from and secured to its inner sides, the plates in one series being arranged alternately, in relation to the plates in the series above or below it, a Water-supply pipe leading into the boiler and thence into the receptacle along its length and having openings or outlets in IO that part of the pipe in the receptacle.
In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
BERNARD MGCABE.
