ABSTRACT:
An improved filter bag assembly is shown for use in a filter bag house having a plurality of filter bags, each of the filter bags being anchored at a lower end and being suspended within the bag house in tensioned relation by an upper end thereof. A bag spring is attached at one side to the bag upper end and has an opposite spring side. The bag spring is tensionable between tensed and relaxed positions. A flexible strap is provided having a spring engaging end attached to the bag spring opposite spring side and has a free end. A hanger is suspended within the filter house and the flexible strap free end is engageable with the hanger when the spring is tensed whereby relaxing the spring serves to tense the filter bag.
Preferably the bag spring is a butterfly-shaped member having a central, helical coil and a pair of angularly arranged spring sides extending outwardly from the coil.
