FREDERICK W. LINAKER AND THEODORE M. BRUBACK, OF DUBOIS, PENNSYLVANIA.

v COMBINED TUBE SYSTEM AND CLEANER.

Application filed October 9, 1920. Serial No. 415,786.

To all whom it may concern.-

Be it known that we, FREDERICK W. LINA- KER and THEODORE M. BRUBAOK, the former a subject of the King of Great Britain, and the latter a citizen of the United States of America, both residing in Dubois, in the county of Clearfield and State of Pennsylvania, have invented certain new and useful Improvements in.Combined Tube Systems and Cleaners, of which the following is a specification.

This invention relates to improvements in tube systems, principally water tube boilers, equipped with compressed fluid cleaner elements, commonly called soot cleaners, and aims to provide improvements therein.

The present invention provides a construction wherein a compressed fluid cleaner may be used in tube systems, without un duly wearing or deteriorating the walls or bafiles, especially in boiler tube systems wherein the flue or pass. in which the cleaner element is located is constricted, and where, for other reasons, the cleaner ele ment must be necessarily placed near: a baffle or wall.

The invention further provides a novel combination and sub-combinations, hereafter more fully set forth and defined in the annexed claims. Two embodiments of the invention are illustrated in the accompanying drawings.

In said drawings Figure 1 is a longitudinal sectional view of a boiler having a tube system of the Babcock & Wilcox type, showing one embodiment of the combination of our invention.

Figures 2 and 3 are detail views, in front and side elevation respectively, of one of the baflie protectors shown in Figure 1.

Figure 4 is a longitudinal sectional view of a boiler, of the Sterling type, and showing a second embodiment of the combination of our invention.

Figures 5 and 6 are detail views, in front and side elevation respectively, of the baflie protectors shown in Figure 4.

Referring to said drawings, A, in Fig. 1, and A, in Fig. 4:, designate a tube system.

In Fig. 1, the tube system is shown as provided with passes P P P formed, in part, of the baffles B B and, in Fig. 4, the tube system is shown as provided with passes P P P P, formed, in part, by the baffles B, B B

In Fig. 1, it will be observed that the pass P is relatively broad at its bottom, and considerably narrower at its top, the baflie B being arranged diagonally of the tube system.

C designates a cleaner element, which is preferably rotatable and movable into and out of the midst of, or a position alongside of, the tube system, as more fully shown and described'in our co-pending application, Serial No. 3599, 144, filed. July 27, 1920, and claimed therein. This cleaner element C is provided with a plurality of jet-forming orifices or nozzles 0, adapted to blow or direct jets of compressed fluid into. the interval between rows of tubes. The element C is most advantageously arranged at right angles to the rows of tubes, so that the jets may reach to the ends of the intervals.

In order to secure the best effect, the upper end of the cleaner C is arranged close to the upper part of the baffle B and, consequently, the jets from the upper nozzles 0, when directed perpendicularly or substan tially perpendicularly tothe upper part of the baflieB impinge against said adjacent part of the baffle with unusual force, and, to protect said adjacentportion of the baffle from the direct action of the upper nozzles,

a baffle protector or protectors F is placed between said cleaner element and the baffle. It will usually be found to be sufiicient to employ these bafile protectors only at the places of greatest proximity between the cleaner element and the bafiie.

This baffle protector F is conveniently in the form of an angle bar, of the height of the interval between tubes, and, when in place, rests on a row of tubes. It will usually not be found necessary that these baffles be coextensive with the arc of movement of the jets, as it will usually be found to be suflicient that the protectors receive the jets in that part of the movement of the element where the jets blow substantially perpendicular to said baffles, as, for example, through an arc of about degrees.

Bafi'le protectors, of the character shown in Figs. 1, 2 and 3 have an advantage as regards the application of the protectors to a tube system which is already enclosed in a furnace. The protectors F may be lowered alongside of the tube system, or through the interval of the tube system, until they reach the row of tubes on which the protector is to rest, whereupon the bar F is turned at right angles so as to lie parallel to the face of the baflle B Referring to Fig. i, it will be seen that the pass 1, in this form of furnace, is of a chimney character, being long and narrow, and hence restricting the space in said pass. C designates a cleaner element, provided with jet-forming nozzles or orifices 0 adapted to project jets of cleaning fluid in the intervals between the I tubes. Said cleaner element C is preferably rotatable, as to sweep the tubes for a considerable length, and preferably from end to end, as here shown.

T he jets from the nozzles 0, when directed perpendicularly to the baffle B in turning in the restricted space in the pass P would strike or impinge with unusual force upon the said baflle B and, to protect the baflie B from the force of said jets, where the jets are in that part of the movement of the cleaner element 0. where they blow substantially perpendicularly to said baffle, there is located, between said element C and the baflle B, a baflie protector F and this protector is preferably of a length corresponding to an arc of movement of the noz zles where the impingement of the jets is substantially perpendicular to the baffle, as, for example, through an arc of 90 degrees of movement of the said element C The baflle protector F is conveniently a piece of sheet metal, which is placed in front of the battle. There are preferably attached to the ba'liie protector F angle pieces 7, which, when the said baflie protector F is placed in a tube interval, serves to prevent looseness of said bafiie protector in the tube interval. The baflie F is conveniently held in place by means of rods f attached to a collar 7, secured, for example, to one of the tubes. Any other method of fastening, however, may be adopted. The sheet metal of the protector is preferably thin enough to be flexible, so that the protector can be slid into place in a tube interval (in an already completed boiler and setting, for example), by sliding it into the space between the tube system and the furnace wall, bending the plate into the intended interval, and then usually turning the plate through an angle of 90 degrees in the plane of the plate.

It will be seen that, in the embodiments shown in Figs. 1 and 4:, the baffles or walls are protected from the force and action of the jets, when blowing directly thereagainst, when the cleaner elements are placed in constricted passes, or necessarily or desirably arranged close to a baffle or wall.

The inventive ideas may receive other embodiments than those herein specifically illustrated and described.

\Vhat is claimed is:

1. In combination, a tube system having a baflle therein, a compressed fluid cleaning element adapted to blow jets of fluid into the intervals in said tube system, and a baifle protector between said cleaning element and said baflle, said cleaner element being rotary, said protector being adapted to receive the impingement of the jets in that part of the movement of the element where they blow substantially perpendicularly to said bathe, and said protector comprising an angle bar confined between rows of tubes.

2. In combination, a tube system having a balfle therein, a compressed fluid cleaning element adapted to blow jets of fluid into the intervals in said tube system, and a baffle protector between said cleaning element and said baflle, said cleaner element being rotary, said protector being adapted to receive the impingement of the jets in that part of the movement of the element where they blow substantially perpendicularly to said baflle, and said baffle protector consist ing of angle bars resting between rows of tubes.

In combination, a tube system having a baflle therein, a compressed fluid cleaning element adapted to blow jets of fluid into the intervals in said tube system, and a baflle protector between said cleaning element and said baifle, said cleaner element being rotary, said protector being adapted to receive the impingement of the jets in that part of the movement of the element where they blow substantially perpendicularly to said baflle, said baflie protector con sisting of angle bars resting between rows of tubes, said baflie being inclined in relation to said cleaner element, and said protectors being located at the part of the baflle nearest said cleaner.

In witness whereof, we have hereunto signed our names.

FREDERICK WV. LINAKER. THEODORE M. BRUBACK.
