Hopper loading directly insertable horizontally mounted cylindrical segmented bore pleated filter system for rotary broom sweepers
First Claim
1. An air filtration system, which comprises:
- a clean air plenum, said clean air plenum, said clean air plenum including a substantially vertical wall having an inlet opening therein;
a pair of substantially horizontal parallel tension bars connected to and extending substantially perpendicular to said plenum wall spaced apart on opposite sides of said plenum inlet;
a gimbal plate positioned between said tension bars;
a filter element positioned between said tension bars and between said gimbal plate and said plenum wall about said inlet opening;
cradle means for supporting said filter element between said tension bars;
and means operably connected to said tension bars for urging said gimbal plate into engagement with said filter element thereby to urge said filter element into engagement with said plenum wall.

Abstract
Disclosed is an air filtration and filter mounting system. The system includes a clean air plenum having a wall with an inlet opening therein. A pair of substantially parallel tension bars are connected to and extend perpendicular to the plenum wall spaced on opposite sides of the plenum inlet. A gimbal plate is slidingly mounted on the tension bars. A filter element is positioned between the tension bars and between the gimbal plate and the plenum wall about the inlet opening. A clamping bar is fixedly connected to the tension bars outward of the gimbal plate and a screw is threadedly engaged with the clamping bar to urge the gimbal plate into clamping engagement with the filter element.

9. A dust and debris collection system for use in a mobile rotary broom sweeper, said system comprising:
-
a hopper positioned in said sweeper, said hopper including a dust and debris inlet and a top wall and a pair of spaced apart side walls; clean air plenum positioned in said hopper, said clean air plenum including a vertical wall having an inlet opening therein; a gimbal plate supported in said hopper for lateral movement with respect to said plenum wall; a filter element positioned between said gimbal plate and said plenum wall; cradle means for supporting said element between said plenum wall and said gimbal plate; and means for urging said gimbal plate into engagement with said filter element, thereby to urge said filter element into engagement with said plenum wall. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17, 18, 19)

20. Apparatus for mounting a filter element in engagement with a substantially vertically oriented air plenum wall of a filtration system, which comprises:
-
a pair of spaced apart substantially horizontal parallel tension bars extending substantially perpendicular from said plenum wall; a clamping bar fixedly connected between said tension bars; cradle means for supporting said filter element between said tension bars; a gimbal plate positioned between said tension bars and between said plenum wall and said clamping bar; and means for urging said gimbal plate apart from said clamping bar. - View Dependent Claims (21, 22, 23, 24)

25. An air filtration system, which comprises:
-
a clean air plenum, said clean air plenum including a substantially vertical wall having an inlet opening therein; a pair of substantially horizontal parallel tension bars connected to and extending substantially perpendicular to said plenum wall spaced apart on opposite sides of said plenum inlet; a gimbal plate positioned between said tension bars; a filter element positioned between said tension bars and between said gimbal plate and said plenum wall about said inlet opening; partition means for dividing the interior of said filter element into at least two longitudinal segments, said partition means including a vertically upstanding partition panel; reverse jet air discharge means disposed adjacent to said plenum inlet for discharging jets of pressure air to backflush said filter element segments; diverter means extending substantially parallel to the exterior of said filter element adjacent to said vertically upstanding partition panel for diverting laterally material flushed from said filter element, thereby to prevent material flushed from the filter element on one side of said vertically upstanding partition panel from being redeposited on the other side of said panel; and means operably connected to said tension bars for urging said gimbal plate into engagement with said filter element thereby to urge said filter element into engagement with said plenum wall.
