This section or segment has a flat I have shown a preferred embodiment of my forward end I9 adapted to seat firmly and fit invention in the accompanying drawing, in closely against the seating face I0 of the portion Which- 9 of the main body 5 of the cooler proper. The 50 Figure 1 is a longitudinal section through the faces 8 of the opening in thel cooler body 5 are improved cinder notch cooler assembly, with the provided with semi-circular notches 2t which are separable section removed; adapted to coact with similar notches 2| formed Figure 2 is a view similar to Figure 1 but showin the meeting faces of the replaceable segment ing the separable section of the main cooler; I3. These notches When in registration are 55 adapted to receive dowel pins which will maintain the parts in proper intertting relationship. The section I8 as shown in Figure 4, is provided with the tapped openings 22, one of which may be used to introduce the cooling iluid and the other to withdraw it.

It will be understood that the assembly will be inserted so as to extend through the furnace Wall with the segment I8 at the lower position as shown in gures of the drawing. Thus when the cooler is used to withdraw cinder from the furnace it will pass over the movable section I8 and will normally never be in suflicient quantity of flow to engage the body of the cooler. It will be understood that normally the cinder will not destroy any portions of the cooler. If, however, in the furnace operation the molten metal gets high enough so that some of it runs out with the cinder, this molten metal may cut through and ruin one or more of the portions of the assembly. If it cuts through the money 1, that may be withdrawn and replaced with a new casting without aiecting the other portions of the assembly. If it should cut through the intermediate section 6, this may be remove-d, carrying with it the monkey which, if not damaged, may be placed in a new intermediate section and the sub-assembly restored to its position in the main body of the unit. As has been previously stated, these replacements require much less loss of time and expense than replacement of the entire assembly.

Similarly, should the main cooler be cut through by the molten metal, this cutting will only affect the segment I8. This segment may be readily removed without disturbing any of the other sections of the assembly. It is merely necessary to knock out the dowels extending into the notches and 2|, whereupon the section may be rea-dily withdrawn and a new one inserted without delay or loss of furnace time.

The construction is so designed that an integral finished surface extending throughout the whole circumference is formed on the main cooler 5 to receive the intermediate cooler 6. This is important in maintaining an airtight joint at this point. It also facilitates removal of the injured section when necessary.

While I have described my invention as a cinder notch cooler, it will be apparent that it may also be used as a tuyre cooler. Tuyre coolers are sometimes burned through by iron burning through blow pipes. With my improved cooler used in tuyres it would save the replacement of the entire cooler in such cases and be effective in the same manner as when used as a cinder notch cooler.

Although I have described my invention with the use of copper as the material, it will be understood that cast iron is sometimes used.

The segment which is inserted may also be made of cast iron, or in some cases, of refractory material, or it may be made of cast iron with a coating of refractory material on a surface where it is not desired to water cool it.

While I have shown one form of my invention, this is to be understood to be illustrative only, as the invention is capable of change and modification to meet varying conditions and requirements and I contemplate such modifications as come within the spirit and scope of the appended claims.

I claim:

1. A furnace wall opening hollow cooler comprising a cooler body generally frusta-conical in shape having its smaller end in the form of an unbroken circle and having a hollow removable section of substantial arcuate and axial extent, said section forming a portion of the larger end of the body and meeting a radial inner face of the circular section adjacent the small end of the body.

2. A furnace wall opening cooler comprising a cooler body generally frusto-conical in shape having its smaller end in the form of an unbroken circle, the inner face of said circle forming a continuous seat, a second cooler member having an outer face engaging said seat, the cooler body having a removable segment extending from the large end of the body to a point adjacent the seat.

Y 3. A furnace wall opening cooler comprising a cooler body generally frusto-conical in shape having its smaller end in the form of an unbroken circle, the inner face of said circle forming a continuous seat, a second cooler member having an outer face engaging said seat, a radially extending face on a portion of the said circular portion adjacent said seat, and a removable segment of the cooler body having an end fitting against said radially extending face.
