2. A mould and core construction for casting, in one piece, a combined gas collector and cell cover for electrolytic cells of the tank type which comprises a bottom forming member, parallel and alternately spaced channel and groove forming cores detachably secured to said bottom member and extending upwardly therefrom, spaced apart side and end forming members supported by said bottom members and enclosing said parallel cores, and fusible cores supported by said channel forming cores, said fusible cores having a relatively low melting temperature which is above the formation temperature of the casting, and detachable cores extending upwardly form said fusible cores above the uppermost surface of the resulting casting, and reinforcing means supported by said fusible cores.

3.A mould and core construction for casting, in one piece, a combined gas collector and cell cover for electrolytic cells of the tank type which comprises a bottom forming member, parallel and alternately spaced channel forming fusible cores and groove forming solid cores, supported by said bottom member and extending upwardly therefrom, spaced apart side and end forming members supported by said bottom member and enclosing said parallel cores, and fusible cores supported by said channel forming cores, said fusible cores having a relatively low melting temperature which is above the formation temperature of the casting, and detachable cores extending upwardly from said fusible cores above the uppermost surface at the resulting casting.


4. A mould and core construction for casing, in one piece, a combined gas collector and cell cover for electrolytic cells of the tank type which comprises a bottom forming member, parallel and alternately spaced channel and groove forming cores supported by said bottom member and extending upwardly therefrom, spaced apart side and end forming members supported by said bottom member and enclosing said parallel cores, and hollow fusible cores supported by said channel forming cores, said hollow fusible cores having a relatively low melting temperature which is above the formation temperature of the casting, and detachable cores supported by said side forming members and extending downwardly and terminating at said channel forming cores, and at least one hollow core extending upwardly from each of said hollow fusible cores and communicating with an opening extending into the interior thereof thereby providing an unobstructed opening extending from the hollow interior of the fusible core to the atmosphere.


5. A mould and core construction for casting, in one piece, a combined gas collector and cell cover for electrolytic cells of the tank type which comprises a bottom forming member, parallel and alternately spaced channel and groove forming cores supported by said bottom member and extending upwardly therefrom, each of said channel forming cores sloping uniformly upwardly from each end to a point spaced apart a predetermined distance from the central vertical axes of said cores, said channel forming cores being alternately positioned whereby the highest points of one set of alternately spaced channel forming cores are in alignment on one side of the central vertical axes of .the said cores and the highest points of the other set of alternately spaced cores are on the other side of said vertical axes, spaced apart side and end forming members enclosing said parallel cores and spaced apart fusible cores
supported by said channel forming cores, a fusible core being supported by the highest part of each set of said cores and extending the full width thereof, said fusible cores having a relatively low melting temperature which is above the formation temperature of the casting, and detachable cores extending upwardly from said fusible cores above the uppermost surface of the resulting casting.


6. A mould and core construction for casting, in one piece, a combined gas collector and cell cover for electrolytic cells of the tank type which comprises a bottom forming member, parallel and alternately spaced channel and groove forming cores supported by said bottom member and extending upwardly therefrom, spaced apart side and end forming members supported by said bottom member and enclosing said parallel cores, and two spaced apart fusible cores supported by said channel forming cores, a fusible core being positioned on each side of the central vertical axes of said parallel cores and extending the full width thereof, said fusible cores having a relatively low melting temperature which is above the formation temperature of the casting, and cores extending upwardly form said fusible cores above the uppermost surface of the resulting casing and detachable cores supported by said side forming members and extending downwardly between the fusible cores and terminating at the channel forming cores.

7. A mould and core construction for casting, in one piece, a combined gas collector and cell cover for electrolytic cells of the tank type which comprises a bottom forming member, parallel and alternately spaced channel and groove forming cores supported by said bottom member and extending upwardly therefrom, spaced apart aide and end forming members supported by said bottom member and enclosing said parallel cores, and fusible cores supported by said channel forming cores, said fusible cores having a relatively low melting temperature which is above the formation temperature of the casing, detachable cores supported by the side forming members and extending downwardly and terminating at said channel forming cores, cores extending upwardly from said fusible cores, and at least one core extending horizontally from each fusible core to the end forming member adjacent thereto.

8. The method of casting, in one piece, a combined gas collector and cell cover for electrolytic cells of the tank type which comprises erecting, on a base, a plurality of parallel and alternately spaced, upwardly extending channel and groove forming cores, and supporting; on the parallel channel forming cores, fusible cores having a relatively low melting temperature which is above the formation temperature of the resulting casting, enclosing the parallel cores with a form of predetermined height above the fusible cores, filling the form with concrete and permitting the concrete to solidify, removing the form and parallel cores, and heating the casting to a temperature above the melting temperature of the fusible cores, and removing the molten core material through openings in the casting.

9. The method of casting, in one piece, a combined gas collector and cell cover for electrolytic cells of the tank type which comprises erecting, on a base, a plurality of parallel and alternately spaced upwardly extending channel forming fusible cores and, groove forming solid cores, and supporting, on the parallel channel forming cores, chamber forming fusible cores having a relatively lowmelt1ng temperature which is above the formation temperature of the resulting casting, enclosing the parallel cores with a form of predetermined height above the chamber forming fusible cores, filling the form with concrete and. permitting the concrete to solidify, removing the form and parallel solid cores, and heating the casting to a temperature above the melting temperature at the said fusible cores, and removing the molten ore material through openings in the casting.

10. The method of casing, in one piece, a combined gas collector and cell cover for electrolytic cells of the tank type which comprises erecting on a base, a plurality of parallel and alternately spaced, upwardly extending channel and groove forming cores, and supporting, on the parallel channel forming cores, hollow fusible cores having a relatively low melting temperature which is above the formation temperature of the resulting casting, enclosing the parallel cores with a form of predetermined height above the hollow fusible cores, filling the form with concrete and permitting the concrete to solidify, removing the form and parallel cores, and heating the casting to a temperature above the melting temperature of the fusible cores, and removing the molten core material through openings in the casting.
