BOILER-TUBE CLEANER.

Specification of Letters Patent.

Patented Apr. 26, 1910.

' To all whom 'it may concem:

Be it known that I, RICHARD W. HAMANN, a citizen of the United States, and resident of St. Louis, Missouri, have invented certain new and useful Improvements in Boiler- Tube Cleaners, of which the following is a specification containing a full, clear, and exact description, reference being had to the accompanying drawings, forming a part hereof.

My invention relates to boiler tube cleaners, my object being to construct a simple apparatus particularly intended for use in connection with water tube boilers, and which apparatus is utilized for directing Jets of steam or compressed air onto and between the water tubes of a boiler for the purpose of removin the soot, ashes and lkel-accumulatlons W ich interfere with the natural draft and heating capacity of the boiler. u

A -further object of my invention is to arrange tubular nozzles on the interior of the boiler furnace Vfor the urpose of 'directing Jets of steam onto and) between the water tubes, -and which tubular nozzles are arranged 1n coverings of fire clay, tile, or the llke, which protect said tubular nozzles from theintense eat and the direct action of the flames within the furnace.

To the above purposes,- my invention'consists in certain novel features of construction and arrangement of parts which will be hereinafter more fully set forth, pointed out in the claims, and illustrated 1n the accompanying drawings, in which:

Figure 1 is a side elevation, partly in section, of a boiler furnace, the same being equipped with my im roved cleaning ap aratus; Fig. 2iis an en arged vertical section taken on the line Qr-Q of Fig. l; Fig. 3 is an enlar ed detail section taken on the line 3-3 of *ig. 2; Fig. 4 is a vertical section taken on the line 4 4 of Fig. 3; and Fig. 5 is a perspective view of one of the protecting members made use of in carrying out my invention. y

Referring by characters to the accolnpanying drawings:` 1 designates the boiler setting, 2 the boiler, 3 the front water leg, 4 the rear water leg, 5 the water tubes connecting the water legs, 6 the bridge wall, 7 the defiector plate located immediately over the bridge wall, and 8 the defiector plate located. a short distance in front of the rear water leg, all of which parts are of 'ordinary well known construction.

As shown in Fig. 1,- I locate one of the tubular nozzles A immediately below the lowermost row of boiler tubes and in front of the upper end of the bridge wall 6, and a second tubular nozzle B is located on top of the uppermost row of water tubes immediately to the rear of the deflector plate 7, while a third tubular nozzle C is located below the lowermost row of water tubes and immediately in front of the lower endv of the rear water le 4. All of these tubular nozzles are alike 1n construction and operation, and therefore but one will be described in detail.

Each tubular nozzle comprises a pipe or tube 9, of suflicient length to extend entirely across the space within the furnace and one end of said tube is closed and is arranged to rock in a bearing 10 located in one of the side walls of the boiler setting, and the opposite end of this tube is connected to a pipe 11, which is arranged to rock in a, bearing 12 located in the opposite side Wall, and said pipe 11 being connected by a. sl1p jolnt 13 to a fluid ressure supply plpe 14, 1n which is located) a cut o'if va ve 15.

Fixed 011 the pipe 11 is a handle 11, by means of which said pipe 'and the tubular nozzle 9 are rocked when in use. v

The pipe 9 forming the tubular nozzle is provided witii a row or rows of perforations, such as 9, and if desired these perforations may be staggered in order to direct the Jets of steam or compressed air in different direc V Vdove-tailed grooves 20 formed in the under sides of the tile, and after the hooks have beerr properly attached and the nuts are tightened on the ends of said hooks, the grooves 20 are filled with plastlc fire clay or like material, which hardens when dry.

The rows of protecting blocks or tile on `the lowermost pair of tubular nozzles A and. C are arranged beneath said nozzles in order to properly protect the same against the heat and flame passing through the furnace, whereas the blocks or tile onthe tubularnozzle B are arranged on top thereof, to protect said nozzle from the heat and flame passing over the top of the delector plate 7.. The tops of the blocks or tile 16 arecutaway on one side of the nozz1e,'as designated by 22, in order that the jets of steam or compressed air issuing from the apertures will `be unobstructed, and said jets can be directed over a considerable boiler tube area, as shown by dotted lines in Fig. 1.

When a cleaning apparatus of my improved construction is 1n use, the valve 15 is opened to permit the 'i'ovv of steam or compressed air through the supply pipe 14 and pipe 11 into the tubularl nozzle 9, and the handle 11 is now manually engaged to lock Y the pipe 11 and tubular 'nozzle 9, and during the locking motion jets of steam, or com-I pressed air issue fromthe apertures 15 and pass over and between the Water tubes 5, thus blowing all soot, ashes and like accumulations from the surfaces of said tubes and causing said accumulations to be carried by the natural and forced draft into the stack leading from the furnace.

The 'blocks or tiles 16 cover the tubular 1 nozzles 9 andyprotect the same from the heat and -the direct action of the flame passing through thev furnace.

-the tubularnozzles of the apparatus are thoroughly the furnace.
