STEAM FLU E-CLEAN ER.
SPECIFICATION forming' part of Letters Patent No. 425,165, dated April 8, 1890.
Application iled February 5, 1890. Serial No. 339,328. (No model.)
To all whom it may concern:
Be it known that I, VILLIAM DOTY, a citizen of the United States, residing at Chillicothe,in thecountyof Ross and State of Ohio, have invented certain new and useful Improvements in Steam Fine-Cleaners; and I do declare the following to be a full, clear, and exact description ot' the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.
My invention relates to steam-boilers; and it consists in an improved device for cleaning the tubes or nues, as hereinafter described, and particularly pointed out in the claims.
Fine-cleaners have long been in use in which a jet of steam is the agency by which the dirt and scale are removed. In some of these the jet has been given a whirling motion like a rifle-ball, to more effectually loosen the foreign substances in the ues. In all these, however, so tar as I am aware, the whirling motion has been imparted to the steam during its passage through a comparatively short portion of the nozzle, and that at the delivery end thereof. I nd in practice that the spiral blades or twists in the nozzle tend to check the tlow of steam at the point where they begin, which causes more or less condensation -of the steam at that point, especiallyT when the steam is first turned on. There is also a checking of the flow when the nozzle is applied to an obstructed tube or flue. The water thus formed is blown into the tubes or iiues, where it iningles with the dirt and ashes and forms a muddy deposit that adheres tenaciously and is extremely difficult to dislodge.
My invention aims to get rid of all the water of condensation at the point where it forms and to deliver only dry steam to the tubes.
In the drawings, Figure 1 is a sectional view of the tire-box and rear portion of a boiler with my line-cleaner inserted into one of the tubes'. Fig. 2 is a view, partly in section, of my nozzle; .and Fig. 3 is an end view of the 5o nozzle on a larger scale.
The bore of thenozzle A is preferably cylindrical, and is provided with a number of spiral ribs a, preferably three, as shown, running the whole length of the nozzle. The passage-way is thus of the same size throughout, so that there will be no choking of the flow of steam after it enters the nozzle. The pitch of the ribs may be varied; but I prefer to give them one complete rotation in about every nine inches. The ribs are of the same height throughout, so that the clear space inside of them (indicated by the central white space in Fig. 3) will not vary. The base of the nozzle is shouldered and screw-threaded, in order that it may be tightly secured to a T-union B. To the upper end of this union is connected a flexible hose O, through which steam may be conveyed to the nozzle.
Directly below the end of the hose C is an automatic drip-valve. This consists, preferably, of a head D, to which may be attached a stem (l, sliding loosely in thebore e of a tubular plug E, which is tapped into the`lower end of the union B. The plug is 4preferably provided with a squared head e fora wrench. The inner end of the plug is faced off to form a seat for the face of the valve. A spring F is coiled in the bore of the plug, one end of the spring being made fast to the valve or its stem, the other end being secured to the plug. The spring is arranged to hold the valve normally open, as shown, but is calculated to close under a suitable pressure of the steam.
The union B is provided with a handle G long enough to enable the cleaner to be inserted into the tubes through the furnacedoor, as shown.
The operation of my device is as follows: Vhen steam is turned into the hose C, it enters the union B, where it is checked by the spirally-ribbed nozzle A, and a portion of it `is condensed.
the open valveD until the nozzle has warmed up and the flow of the whirling steam-jet has been established. The back-pressure in the union B, caused by inserting the nozzle into an obstructed tube, is sufficient to close the valveD and hold it. The water of condensation forming after this will collect above the valve and will be blown out as often as the The water blows out through IOO nozzle is removed from a tube and the bacio pressure on the valve is relieved. 3y this arrangement none but dry steam will be delivered to the tubes, and the difficulties occasioned by moist steam are entirely obviated.
My automatic drip-valve can be used to advantage with nozzles of any construction, though I regard it as especially well adapted for those in which a whirling motion is given to the jet. A
Having thus described my invention, what I claim, and desire to secure by Letters Patent, 1s-
1. A steam-jet liuc-cleaner having a nozzle containing a cylindrical passage-Way provided with spirally-arranged ribs extending from one end to the other, whereby the flow of steam is not choked after it enters the nozzie, substantially as described.
El. A steam-jet flue-cleaner provided with an automatic drip-valve for the escape of the water of condensation, substantially as described.
3. A steam-jet Hue-cleaner having a noz '/.le adapted to give the jet a whirling motion and an automatic drip-valve situated at the base of said nozzle, substantially as described.
4. In a steam-jet flue-cleaner, the combination, with the spirally-ribbed nozzle A, of the T-union B and the automatic drip-valve D, located at the lower end of the union, substantially as described.
5. In a steam-jet flue-cleaner, the combination, with the nozzle A, of the union B, the tubular plug l, tapped into one end of said union, the valve D, adapted to seat against the inner end of the plug, and the spring F, attached to the valve and to the plug, substantially as described.
In testimony whereof I aiix my signature in presence of two witnesses.
