ABSTRACT:
A resiliently supported filter support plate, with tubular filters depending therefrom, is provided with an overlying rock shaft carrying rocker arms having depending hammer heads arranged to strike and jar the filter mounting plate to shake off the filter cake. A resilient crank arm is connected to the rock shaft and is provided with parallel, cantilever mounted leaf springs that receive an eccentric drive roller which oscillates the rock shaft through one or the other of the leaf springs and causes the hammer heads to strike the filter support plate before the striking stroke of the roller has been completed. The driven leaf spring is then deflected by the roller as it completes its striking stroke, further motion of the hammer heads having been interrupted by the filter support plate. On the hammer lift stroke the eccentric roller retracts the hammer via the other leaf spring. Two embodiments are shown; a dual hammer form with hammers projecting in opposite directions from the rock shaft and a single hammer form wherein a single row of banners project in one direction from the rock shaft.
