the blower type, and refers more particularly to an improved construction adapted for use as a side unit.

Among the objects of the invention are to provide a side unit which can be adjustably actuated from the exterior of the furnace wall; to so arrange and mount the unit that the nozzles can be rotatably withdrawn to a position protected from the furnace heat when not in use; to provide a mounting that will permit the nozzle header to be rotatably adjusted through an arc of approximately 180; and to provide a frame box for the blower unit which both contains the blower and forms a support in the setting Wall.

The invention further resides in the simplified construction of the blower unit and its operating mechanism, and also in the arrangement whereby the work of installation and operation is materially reduced, and in such details of construction and arrangements and combinations of parts as will hereinafter appear.

In the drawings:

Figure 1 is a front elevational view of a blower unit embodying my invention;

Fig. 2 is a side elevational view of the construction shown in Fig. 1;

Fig. 3 is a top plan view thereof; and

Fig. 4 is a cross-sectional View of a modified construction of nozzle header.

In detail, A designates the furnace wall, having an opening B within which fits a frame-box C. The latter is preferably formed of cast iron or other material sufiiciently strong to support a part of the setting wall, as well as forming a housing for the blower unit D.

The blower unit comprises a nozzle header F provided with a plurality of nozzles G spaced to blow between the boiler tubes G. This nozzle header is carried by a pipe E, which at its lower end is connected by a coupling H to a pipe I rotatably mounted in bearing supports J. The pipe I, in

turn, is connected by a swiveled pipe connection coupling L to a'steam pipe M. The arrangement is such that the pipe E carrying the nozzle header F can be rotatably'adjusted about the pipe I as an axis. This adjustment permits the nozzle header to be rotatably withdrawn into the frame-box and away from the furnace heat when not in use. When it is desired to clean the boiler tubes, it'is only necessary to rock the pipe E and the nozzle header F about its axis so as to successively direct the nozzles (Jr against the various boiler tubes. WVhere the nozzle header is provided with a single row of nozzles, the lower wall of the frame-box C is cut away, as shown at G, to permit the pipe E to be rocked about the axis I through an arc of approximately 180, to the posi tion shown in dotted lines in Fig. 2. Thus, upon the initial movement of the header the nozzles G will dischaige a jet of steam upwardly to clean the top portions of the boiler tubes, and will, upon its continued rotation, successively clean all portions of the boiler tubes G. In place of rotating the header and its supporting pipe E through so large an arc, the header may be supplied with an additional row of nozzles G as shown in Fig. 4.

For manually operating the nozzle header from the exterior of the furnace wall, I preferably provide the pipe E with a fitting N, to which is pivotally connected at 0 an operating rod P. The latter extends outward through the front wall Q of the frame box, and at its end is provided with an operating handle B. At the point where the operating rod P passes through the wall of the frame-box, there is preferably an elongated slot S, so that the nozzle header can be turned through the desired arc.

The invention, however, is not limited to the particular operating mechanism shown, nor to the details of construction except as specified in the appended claims.

What I claim as my invention is 1. In a boiler cleaner, the combination with aframe box adapted to be set in the furnace wall, said box having a plate substantially flush with the outer surface of said wall, of a supply pipe extending into said frame box, a pipe having swivel connection with said supply pipe within said box, a header carried by the last mentioned pipe and extending parallel to the axis of swivel motion, and a member for actuating swivel motion extending from the swinging pipe through said plate at the front of the frame box.

2. In a boiler cleaner, the combination with a furnace wall, of a casing mounted in said wall, a steam pipe entering said casing, a pipe having swivel connection with said steam pipe at one end thereof, a jet header mounted upon the other end of the 1ast-mentioned pipe, said header being displaced through angular motion of said swivel pipe from a position within said casing to a position beneath the casing, and means for manually actuating said motion.

3. In a boiler cleaner, the combination with a frame-box adapted to be set in the furnace wall, of a steam supply pipe extending into said box, an adjustable pipe having swivel connection within said box and adjacent one of the walls thereof with said supply pipe, said wall having a cutaway portion to increase the are through which the adjustable pipe may swing, a jet header carried by the free end of the adjustable pipe and displaceable by said pipe from a position within the frame-box to various positions exterior thereto, and means for swivelly displacing the adjustable pipe.

In testimony whereof I atlix my signature.

FRANK MCILVANE.
