The nozzles in practice have e. I definite range of oscillation acrossthe openings 3 in planes substantially parallel to the boiler times; so as to take inns lei'ge a section of the tubes as possible during the;blowiiig'opemtion.

Any means for imparting oscillation to the nozzles may be adopted, the mechanism shown not boom-herein claimed, constitutiog us it does llie subject-matter of a dire tmctr application It may However, be

the wall-plate P and through which the noz- 'zles 1 project, are more than suflicient to allow for the necessary oscillation or traverse imparted to the nozzles; and in the present especially while the boiler is being blown,

suchlair tending not only to chill th tubes,

but to condense the steam employed for cleaning purposes, In the present improvement this exclusion of atmospheric .air is f accomplished by the flange 1 0" fo1ming'an extension ofthe outer stationary member or casing 10 of the hollow joint (the member 10 constituting the inner rotatable member of said joint), said flange being inthe nature of an a min or shield and being bolted directly to the plate-l "or apron the nozzle has ample room to oscillate, and a sliding plate mounted on the 1102- zle across the slot, such as shown in any pendin application aforesaid is unnecessary; besides, the present improvement is much more ractical and eminently more desirable. T e flange (10") engaging the late 1? forms a tight joint therewith, and likewise a chamber a' forample-accommodationof the oscillating nozzle 1. In practice of course, the plate I may be dispensed with, but as it is already builtin the walls of the majority of existing furnaces, it need not be disturbed. In my present improve- .ment therefore, the air-excluding member, flange or shield 'for the slot 8 is directly identified with the stationary member of the hollow swing joint. In the claims, the opening across which the nozzle is stated to, operate, is to be'understood as the slot sf (or its equivalent) in the plate P (or its equivalent) through which the nozzle passes and which it traverses in its oscillations. The 'flange 10 is herein identified with the peripheral walls of the outer joint casing 10, the ends, of the latter being closed by.

the rotatable member 10. The details of the hollow joint in particular not here referred to are not claimed, forming as they do, the subject-matter of my pending application for'boiler-cleaners filed Dec. 1, 1911, Serial Number 663,350. z

No particulanmcthod of fastening the plate I is here claimed. The plate is bent to conform to the contour of the wall-plate P and the converging walls of the outer portions of the window or opcningO. Refer- 'By then driving home Vithin this shield leading through said opening, and

ring particularly .to Fig. 3, advantage is taken of the metal strips t identified with boiler-furnaces. By bending the sheet composing the plate 'P so as to engage the outer edges of the strips t, the spring of the metal of the sheet will sufiice to keep the plate-P the wall-plate P and present in existing wedged "between the strips. If necessary,

nails may be driventhrough the outer flaring portions or Wings of the plate lnto the brick-work. 'To better adjust the length of the plate I" to the heights of the openings O of different boiler furnaces, I prefer to firstv place a narrow section P', at the top of the opening 4), then lap the main section (fig.
