corner parts of the melting and Working chambers and to eliminate short circuit flow of the glass-metal from the charging holes of the melting chamber to the discharge hole of the working chamber.
The invention consists in the novel construction and combinations of parts as set forth in the appended claims.
In the accompanying drawings illustrating embodiments of the invention:
Figure l is a section on line CC, F igure 2.
Figure 2 is a composite section on the lines B-l3 and G-G, Figure 1.
Figure 3 is a similar section on lines FF, and A-A, Fig. 2.
Figures 4, 5, 6, 7, 8, and 9, are composite diagrammatic views showing modifications.
In these drawings, the numeral 1 designates a melting chamber of a glass tank furnace in which the raw material is melted, after being fed through charging holes 2, and 3 is the refining or working chamber, connected with the melting chamber by a contracted depressed passage or throat 4 of considerably less Width than that of said chambers, in a contracted intermediate portion of the furnace, this being a common type of furnace.
In the present case, the depressed passage or throat 4 is provided with inclined flared approaches 5, in the floor of said chamber and extending the full Width and at both sides thereof, whereby the flow of the metal into said throat will extend the full width of said chamber from the outer lateral to the central parts thereof, being more accentuated at the central parts where there is more of .a dropto the incline of the approach.
Thedepressed passage or throat 4.- is also provided with inclined and flared exits 6 in the floor of the working chamber at the inner end thereof and extending the full width and at both sides thereof, whereby the flow of the metal from said depressed throat,will
extend the full Width of the working chamber from the central parts to the outer lateral parts thereof.
Modifications of these inclined approaches and exits are-shown in Figures 4:, 5, 6, 7, 8, w
and 9, of the drawings difi'ering in respect of the shape of the inclined and the shape of the flare, there being no flare in the inclined exits of Figure 6. These inclined approaches and exits of the modifications are designed respectively 5a, 5b, 5c, 5d, 5e, 6a, 6?), 60, 6d, and 66, the melting and Working chambers being differentiated by similar exponents. Figures 5 and '9 show modified charging ports 2a, one adjacent each rear corner of the melting chamber, in the rear end wall thereof, instead of in the side walls thereof, 4 as in Figure 2. Figure 7 shows a single .central charging port 26 in of the melting chamber.
In Figures 2, 5, 7, and 9 of the drawings, the lateral passages 5, 5a, 56, 5d, 56, are each provided with an entrance, which is spaced from the related charging port 2, 2a, 26, by
a distance which is less than the distance between charging port and depressed throat 4, thereby accomplishing a drag of the metal from charging port to depressed throat by Way of said lateral passages, rat-her than direct to said defrom the charging port pressed throat. I v
Due to the location of the charging ports, one adjacent each rear corner of the melting chamber, there will be accomplished a direct drag of the metal from the charging ports to the lateral sloping-bottom passages 5, to the depressed throat 4, along the side walls of the melting chamber. Due also to the location of the charging ports relative to the sloping-bottom lateral passages 5 in the floor of the melting chamber and leading downwardly from dead corner parts of the melting chamber to the depressed throat 4, so
that the distance between a charging port and an entrance to said rear end wall a lateral passage 5 is less melting and working chambers and el-imi- I circuit flow of the metal from nating short opening of the melting chamthe charging her to the discharge opening of the working chamber.
I claim: 1. In a glass tank furnace, having a melting chamber and a working chamber both of the usual rectangular construction, said chambers having a contracted depressed throat connecting and of considerably less width than that of the same; the floor of the melting chamber having adjacent said throat opposite lateral passages provide each with an inclined floor forming an approach to said throat and leading downwardly from a dead corner part of said melting chamber, whereby the flow of the metal into said throat will be caused to extend the full width of said chamber from the outer lateral parts to the central part thereof. 7
2. In a glass tank furnace, having a melting chamber and a working chamber both of the usual rectangular construction, said chambers having a contracted depressed throat connecting and of considerably less width than that of the same; the floor of the working chamber having adjacent said throat opposite lateral passages provided each with an inclined floor leading upwardly to a corner part of said working chamber whereby the flow of the metal from said throat will extend the full width of said chamber from the central to the outer lateral parts thereof.
3. In a glass tank furnace, having a melting chamber and a working chamber both of the usual rectangular construction having each a substantially horizontal floor and substantially vertical sides, said chambers having a contracted depressed throat connecting and of considerably less width than that of the same; the floor of the melting chamber having adjacent said throat opposite lateral passages provided each with an inclined'floor forming an approach to said throat and leading downwardly from a dead corner part of said melting chamber, and the floor of the working chamber having adjacent said throat opposite lateral passages provided each with an inclined floor form ing an exit from said throat and leading upwardly to a corner part of the working chamber.
