  • Sheet metal attachment system and method for installation of mine brattices
    Patent number: 4397224
    Abstract: A sheet metal attachment system and method for the installation of underground mine brattices of the type in which a gas impervious barrier of malleable sheet metal is retained on a peripheral framework of slotted beams. The fastening system involves pre-mounting a plurality of bolts projecting from one face of the framework as piercing pins so that the sheet metal may be initially applied by forcing it over the pins. The pierced sheet metal is then drawn against the framework by a multi-apertured washer plate and barrier mounting nut threaded onto the bolts.
