ABSTRACT:
The bottom wall of a filter housing is provided with a flow opening and the top of the housing has an access opening normally closed by a cover. A partition wall in the housing is provided with a passage to permit a filter to be moved into and out of the space below that wall. The side of the housing has a flow opening below the partition wall. A filter in the housing engages the bottom wall around its flow opening, with the top of the filter spaced below the partition wall passage. The partition wall is provided around its passage with threaded holes, into each of which is screwed a threaded portion of a shaft having a head at its upper end for turning it, and a foot at its lower end beside the filter. The outer end of a push bar is rotatably mounted on the lower end portion of the shaft adjacent its foot, and the inner ends of the bars overlap the top of the filter. The shafts are provided with means for pressing the bars down against the filter when the shafts are turned by their heads to move them downwardly, and when the shafts are rotated in the opposite direction the pressure of the bars against the filter is released and the bars are swung away from the filter.
