s claims. (o1. 12a- 389)V The invention relates to boiler cleaners and skimmers, and has for its object to provide a device of this character comprising a scum conduit float supported within the boiler above the tubes -Y thereof and having a flexible connection with a skimmer line extending through the wall of the boiler and valve controlled, and chambered members carried by the fioat and` skimmer conduit at `opposite sides thereof and into which skimmer;

'members foam andscum are forced during the circulation of the water within the boiler.

A further object is to provide the skimmer conduit with upwardly extending arms supporting the oppositely extending skimmer cups and to dispose the floats between the skimmer cups and bracket connections between the floats and the` skimmer cups. Y

A further object is to taper or flare outwardly the skimmer cups whereby scum will be gathered over a large surface of the water during the circulation of water in the boiler.

With the above and other objects in view the invention resides in the combination and arrangement of parts as hereinafter set forth, shown in the drawings, described and claimed, it being understood that changes in the precise embodiment of the invention may be made within the scope of what is claimed without departing from the spirit of the invention.

In the drawings:

Figure 1 is a vertical longitudinal sectional view through a conventional form of boiler showing the device applied thereto.

Figure 2 is a perspective View of one of the skimmer elements.

Figure 3 is a vertical longitudinal sectional View through a portion of one of the skimmer units.

Figure 4 is a bottom plan View of a portion of the conduit in the bottom of the boiler.

Figure 5 is a vertical longitudinal sectional view through a portion of the conduit in the bottom of the boiler.

Figure 6 is a horizontal sectional view taken on line 6-6 of Figure 1.

Figure 7 is a vertical transverse sectional view taken on line l-l of Figure 1.

Figure 8 is a perspective view of a portion of the blow-out conduits around the i'lre box.

Figure 9 is a vertical transverse sectional view through one of the blow-out cups above the re box and a portion of the conduit.

Referring to the drawings, the numeral I designates a conventional form of boiler of the locomotive type, 2 the re box thereof and 3 the boiler tubes, all of which is conventional structure. The

nre box 2 is supported on the usual mud ring 4 forming a chamber 5 below the re box and in which mud collects. Disposed Within the chamber 5 is a rectangular portion tof the gathering or mud blow on" pipe, and through which mud is forced by pressure within the boiler when the blow oi valve l is opened. Extending upwardly from one side of the blow oif pipe portion 6 is a pipe 8 having a flexible pipe connection 9 which connects it to the gathering line AIll in the bottom of the boiler below the boiler tubes 3.

When it is desired to remove the mud from the bottom of the boiler chamber and from the endless chamber 5 beneath the fire box 2 the operator opens the blow off valve 1 and as the steam Within the boiler above the water line II will pass through the skimmer cup I2 the pipes I3 connecting the cups to the skimmer line I4 and the exible pipe connection I5 between the skimmer line Ill and the mud gathering line I0 in combination with the pressure within the boiler, mud will be forced from the boiler by pressure within the boiler. By providing the exible connection I5 between the gathering line I0 and the skimmer pipe I4, it will be seen that the skimmer cups I2 and line I4, which are float controlled by means of the float I6, will be supported where the cups will receive scum from the top of the water in the boiler as the water circulates. When it is desired to skim the water within the boiler, the skimmer valve I'! is opened, which skimmer valve iscarried by the discharge pipe I9 outside the boiler and extends into the boiler and terminates in a exible pipe connection 20, which connects it tol the skimmer line I4, therefore it will be seen there may be a skimming operation as well as a mud discharging operation from the bottom of the boiler either simultaneously or independently. Extending upwardly from the gathering line portion 6 are vertical pipes ZI which terminate in horizontal pipes 22 disposed above the re box 2. The horizontal pipes 22 are provided with downwardly extending and iiared siphon cups 23, which terminate adjacent the in rectangular shaped portions 25 having chambers therein and that the pipes I3 connect the portions 25 to the scum pipe line I4 for the passage of the scum and they also perform the function of a supporting means for the scum cup, thereby obviating the use of special supporting brackets for the cups.

y The gathering line I is built up from a plurality of members, which members are designated by the numerals 26 and 2l. The members 26 are connected together by the members 21 which are inthe form of nipples, the Lends of yvhich are threaded at 28 into the ends of the members 26.

with .downwardly extending lugs 30, which en" gagegthe bottom ofthe boiler and maintain the gathering line upwardly spaced` therefrom,

s The flexible connections 9, I5 and 20 allow the pipes Vto accommodate themselves to the parts of the boiler and to absorb any expansion or convtraction which may` occur so that there will be no breakage of the pipes or repairs required. These flexible connections are also of assistance in assembling and installing therapparatus.

,; From the aboveit will be seen that a boiler cleaning and skimming device is provided which is simple in construction and one which may be easily and quickly applied to a boiler. It will also be noted that the forward end of the boiler is provided with a clean out plate 3l which plate may be removed when it is desired to have access to the gathering line for repair purposes and that the removable clean out plate 3l is adjacent one end of theY gathering line; The invention having been set forth what is claimed as new and useful is:

1. A boiler skimmer comprising a skimmer line jadjacent the waterlevel in a boiler, upwardly extending pipes carr'ied by said skimmer line in spaced relation, float means between said upwardly extending pipes and gathering cups supported by said upwardly extending pipes at opposite sides ,of thefloats.

2. A boiler skimmer comprising a skimmer line,

upwardly extending spaced pipes carried by said skimmer line, a float disposed between said upwardly extending pipes and skimmer cups carried by the upwardly extending pipes and forming a, connectionV between the upwardly extending pipes and the oat.

, 3. A device as set forth in claim 2 wherein the skimmercups are outwardly flared and have their inner reduced ends connected to the upwardly extending pipes and the float.
