Claim 10

The wall as defined in claim 6, wherein some of said studs are each a one-piece metal channel having means for engaging the liner members on more than one vertical side thereof; said wall comprising means, including said engaging means of said one-piece metal channel and independent of said floor runner, for engaging said liner members on three vertical sides thereof.

Claim 11

The wall as defined in claim 6 wherein said shaft is an elevator shaft.

Claim 12

An air shaft wall in a building generally surrounding a vertical air shaft extending continuously, the wall comprising at least one floor having an edge adjacent the continuous shaft, means for mounting a stud in a vertical disposition, said stud-mounting means comprising a floor runner attached to said floor, said runner having at leasT one flange, at least two liner panel members one side of which is exposed to the shaft, means for abutting said one side to the flange of the runner, at least one stud characterized by means for engaging said liner members on more than one vertical side thereof, means, including said engaging means of said stud and independent of said floor runner, for engaging the liner members on three vertical sides thereof, and means for erecting at least one partition member away from the shaft and spaced from said liner members so as to leave an air gap therebetween, said erecting means being independent of said liner members.

Claim 13

An air shaft wall in a building generally surrounding a vertical air shaft extending continuously, the wall comprising at least one floor having an edge adjacent the continuous shaft, means for mounting a stud in a vertical disposition, said stud-mounting means comprising a floor runner attached to said floor, said runner having at leasT one flange, at least two liner panel members one side of which is exposed to the shaft, means for abutting said one side to the flange of the runner, at least one stud characterized by means for engaging said liner members on more than one vertical side thereof, means, including said engaging means of said stud and independent of said floor runner, for engaging the liner members on three vertical sides thereof, and means for erecting at least one partition member away from the shaft and spaced from said liner members so as to leave an air gap therebetween, said erecting means being independent of said liner members.
