Abstract
A sagger construction is disclosed for holding refractory articles during firing. The construction comprises at least two, separable, normally bottomless, topless, multi-sided saggers placed atop each other in substantial vertical alignment to define a hollow columnar enclosure which is adapted to contain the refractory articles. The topmost sagger defines an entrance to the columnar enclosure, while the bottommost sagger has closure means along the bottom thereof and contains exit means for release of the refractory articles such as after firing. This construction not only substantially increases the volume of refractory material which can be fired at one time, but also appreciably reduces labor requirements while prolonging the useful life of the individual saggers.

Apparatus of the class described including a plurality of bottomless and topless, separable, closed frame members defining sagger means stacked atop each other to form a columnar enclosure substatially free of internal support, one of said frame members adjacent the bottom of said columnar enclosure having exit means mounted on the exterior of said one frame member for reciprocation between closed and open positions.
Sagger construction for holding refractory articles during the firing thereof, said construction comprising generally at least two separable, bottomless, topless multi-sided sagger members placed atop each other in substantially vertical alignment to define a hollow column adapted to contain said refractory articles and being substantially free of internal support for such articles, the topmost sagger member defining an entrance to the column, and the bottommust sagger member having closure means along the bottom thereof and containing exit means for release of said refractory articles, said exit means being mounted on the exterior of said bottom most sagger member for reciprocation between closed and open positions in a direction generally parallel to a longitudinal axis of said hollow column.
