Filter apparatus for sweeper truck hopper
First Claim
1. A filter apparatus for use in a sweeper truck, the apparatus comprising:
- (a) a main frame portion adapted for generally horizontal attachment within a hopper section of the sweeper truck, the main frame portion comprising a generally rectangular main frame comprised of four main frame members connected end to end at right angles to one another, a main screen portion extending across the main frame between two or more of the main frame members;
(b) a mechanism for attaching the filter apparatus within the sweeper tuck; and
(c) at least one V-shaped filter section extending downwardly from the main frame portion in a generally vertical direction, an upper portion of the V-shaped filter section being attached to the main frame portion, each V-shaped filter section being at least partially covered with a screen;
wherein the V-shaped filter section is comprised of two generally rectangular-shaped side portions, each side portion being comprised of an upper and a lower long side frame member, each long side frame member having two opposite ends and being attached at both ends to opposite ends of two short side frame members at right angles to one another, the long side frame members being longer in length than a short side frame members, each side portion further comprising a side portion of the screen, the side screen portion extending between the side frame members, the lower long side frame members of each side portion in a V-shaped filter section being adjacent to one other; and
wherein the upper long side frame members extend across a portion of the main screen portion of the main frame portion, and the long side frame members of each side portion of each V-shaped filter section are generally parallel to one other.

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).
