Abstract
A filter apparatus (10) for use in a hopper section (11) of a sweeper truck includes: (a) a horizontal, rectangular, screened main frame portion (20) for attachment within the hopper section (11), (b) a mechanism for attaching the filter apparatus (10) to the hopper section (11); and (c) at least one V-shaped filter section (26), which extends downwardly to a point from the main frame portion (20) in a vertical direction, an upper portion of the V-shaped filter section being attached to the main frame portion, the V-shaped filter section being covered with a screen. Also included is a V-shaped filter device, which includes: (a) two rectangular, similarly-shaped, screened side portions (27) extending in a downward direction from an upper portion of the hopper section (11), the side portions (27) being joined to each other along their base; (b) two triangular shaped end screen portions (33), extending across the ends of the V-shaped filter device (26); (c) a mechanism of attaching (22) the V-shaped filter device to the hopper section; and (d) a mechanism for opening (31, 32) and closing one of the side portions (27) along its base. The V-shaped filter device (26) deflects debris downward into the bottom of the hopper and temporarily collects debris between the side portions (27).

14. A V-shaped filter device for use in a vacuum sweeper truck, comprising:
-
(a) two generally rectangular, similarly-shaped side portions forming the sides of the V-shaped filter device, the side portions being adapted to extend in a downward direction from an upper portion of a hopper section of the sweeper truck, each side portion further comprising a side screen portion extending across the side portion, the side portions being joined to each other along their base;
(b) two generally triangular shaped end screen portions, each attached along one of its sides to a side of the side portion, each end screen portion extending across an end of the V-shaped filter device;
(c) an attachment mechanism along an upper part of the side portion for attaching the device to the sweeper truck; and
(d) a mechanism for opening and closing one of the side portions along its base;
wherein the V-shaped filter device is adapted for deflecting debris downward and for temporarily collecting debris between the side portions.
