Application led October 28, 1924.. Serial No. 746,318.
My invention relates to door frames and the metal adjacent. the frame, to facilitate is particularly applicable to water-cooled m removal of the frame without injury to the door framesfor blast furnaces. The particular object of my invention is to provide a new and improved frame of this type. In
the drawings accompanying this specifica-v vtion and forming a part thereof I have shown, for purposes of illustration, one form which my invention may assume. In these drawings: j
Figure 1 is a front perspective of this illustrative' embodiment of my invention,
Figure 2'is a section on the` line 2 -2 of vFigures 1 and 3, showing also the adjacent portions of afurnace with which this illustrative embodiment of my invention may be- .on the line 3-3 .of-
used,
Figure 3 is a section Figure 2, while Figure 4 is a section on the line 4 4 of Figure 2.
The furnace door frame herein shown comprises a pair of legs 11 united at their upper ends by a cross piece 12 and forming with the cross piece 12 a frame work 13 in the general shape of an inverted U and `divided by' an annularly extending shoulder 14 into a portion 15 arranged to overlie the front face 16 of the furnace wall 17 and a portion 18 arranged to-extend Within the furnace port 19 and formed to closely engage the sides 20 and top 21 of the port 19 and support and protect the furnace wall 17. The portion 15 is provided with pro,- jections 22 arranged toform faces 23 adaptv ed to guide the furnace door, the entire in-l tegral framework 13 is divided by means of a transverse partition 24 into a 'plurality of annularly segmental-sections 25 provided with cooling water cavities 26 each independent ofeach other, the legs 11` are cut away at their lowerinner corners 27 Where theywould4 otherwise closely approach the bank'28, and the entire extension 18 is ta pered upon its port wall engaging face 2.9 to facilitate withdrawal' of the door frame from the port.
It will be understood by those skilled lin the art that the furnace door frame herein shown and described thoroughly supports' Vand protects the furnace wall. ad acent the port, and is formed to prevent cinl ing of vadvantages other than vthose specifically pointed out and also that the particular embodiment of my invention herein shown and described may be variously changed and modified Without departing from the spirit of my invention or sacrificing the advantages thereof. It will therefore be understood that this disclosure is illustrative only and that my invention is not limited thereto.
I claim: 1. In an open hearth' furnace, a water cooled furnace door frame comprising a portion overlying the adjacent furnace wall and a water cooled-inverted U-shaped ex-v tension projecting from said portion within the furnace port, overlying the sides of said port, extending down to substantially the level of the molten metal within the furnace, and cut away atl its lower inner corners.` 2. In an open hearth furnace,. a water cooled furnace door frame comprising a portion overlying the adjacent furnace Wall and water cooled legs projecting from said portion within the furnace port, overlying the sides of said port, extending down to substantial] the level of the molten metal` within the urnace, and each cut, away at4 its lower inner corner. f
3.*In an open hearth furnace, a water cooled furnace door frame comprising a lWater cooled inverted U-shaped extension to substantially thelevel of the molten metal within the furnace, and cut away atits lower inner corners;
4. A furnace door frame 'for the furnace i portAof a masonry .wall`furnace, comprising .an extension projecting within said furnace port andenga'ging the port surface of the furnace- Wall along a surface of contact at all points substantially parallel tothe axis -ofsaid lp'ortyto thus directly and positively support said wall at said port and against movement into 'said port, but tapered slightly to facilitate withdrawal of said frame from said port. Y
5. In an open hearth furnace, a water cooled-furnace door frame comprising water cooled legs projecting within the furnace port, overlying the sides of said port, extending down to substantially the level of the molten metal within the furnace, and-10 each cut away at its lower inner corner.
In testimony whereof, I hereunto affix my signature.
GEORGE D. ROSENBERG.
