Application filed March 30, 1922, Serial No. 548,000. Renewed September 19, 1928 This invention relates to soot cleaners for locomotives of that type which comprises a nozzle or jet pipe which is normally received.

in a pocket formed in the water leg of the boiler at the side of the fire-box but which may be projected from the pocket into the firebox while steam isdelivered therefrom into and through the fiues for cleaning them. One of the objects of the invention is to provide an improved soot cleaner of this type in which the means for projecting the nozzle orjet' pipe from the pocket into the fire-box and also the means for turning the jet pipe on its axis, are located in close'proximity to each other so that they can be easily manipulated.

Another object of the invention is to provide a soot cleaner having novel means for turning the nozzle on its axisby which the movement of the nozzle can be accurately controlled, thus making it possible to thoroughly clean all of the flues.

Other objects of my invention are to improve generally soot cleaners ofthis type all as will be more fully hereinafter set forth;

In order to given an understanding of the invention I have illustrated in the drawings a selected embodiment thereof which will now be described after which the novel features will be pointed out in the appended claims.

Fig. 1 is a fragmentary Sectional view through a portion of a locomotive boiler showing my improved soot cleaner applied thereto. 7

Fig. 2 is an enlarged section on substantial-. ly the line 22, Fig. 1.

Fig. 3 is a section on the line 33, Fig. 4.

Fig. 4 is a view of the soot cleaner looking toward the right in Fig. 2 with a part broken out to better show the construction.

Fig. 5 is a sectional view of one of the swivel j olnts.

In Fig. 1 of the drawings I have shown in horizontal section a suflicient portion of the fire-box to enable my invention to be understood and in said figure, 1 indicates the barrel of the locomotive boiler which is provided with the combustion chamber 2 therein forwardly of which is the usual flue sheet 3 carrying one end of the fiues 4 that lead into thefire-box. At the side ofthe fire-box. is the usual water leg 5 formed between the inner and outer sheets 6 and 7 and this water leg extends around to the front of the fire-box.

tion chamber is indicated at 8, and 90indi- 1 and in full lines Fig. 3 when for cleaning the flues, and my invention re cates in section the wall of the cab. It will be understood that Fig. 1 is intended to indicate a horizontal section through the firebox of the boiler. 2

My improved soot cleaner is of the familiar. type which embodies a jet nozzle 9 having a jet opening 10 therein through which steam is adapted to be delivered against the flue sheet 3 for blowing out the flues. This jet nozzle is normally confined withinv a pocket 11 formed in the water leg 5, said pocket being hereln shown as constituted by a tube 12 extending across the space between the sheets.

6 and 7. This jet. nozzle 9 is arranged to be withdrawn intofthe pocket as shown in dotted lines Fig. 3 when it' is not in use, and to be pro ected into the fire-box as shown in Fig. it is to be used lates to novel means for manipulating the nozzle to project it into the fire-box and then to turn it about its axis so that the steam issuing therefrom will be directed toward any horizontal row of flues.

Secured to the outside sheet '7 is a fitting or casing 13 havinga steam passage 14 leadng to a chamber 15. A steam pipe 16 leads mto the passage 14, said steam pipe communieating with a steam boiler or other suitable source of supply.

The nozzle 9 has a hollow stem or pipe17 extending into the chamber 15 and provided with ports 18 which communicate with the chamber when the nozzle is projected. The chamber 15 hasan extension 19' at its rear end into which the ported end of the stem 17 is received when the nozzle is retracted, and this chamber is of a sizeto fit the stern so that when the nozzle is retracted, as shown in dotted lines the ports are closed by the walls of the chamber extension 19 thus shutting off steam from the nozzle. The stem is formed with the shoulder 22 which seats against the inner wall 23 of the chamber extension 19 when the nozzle is retracted thereby assisting in preventing leakage of steam past the stem. 7 The stem or pipe 17 is extendedor rothe fire-box and also for turning the stem are connected to the end of the stem extension 20.

The fitting 13 is shown as having a rock shaft 24 journalled therein which is pro- "side the boiler and is )lfOYl Le titled with two arms situated at either side of the fittiiii liese a1 ns have 11 ks 26 pivotally connected" tbereto at'27, said; links in turn being pivoted to a collaror yoke 28 Which is swiyelled Q11 the lend of the stem extension 20.
