Abstract
Abstract An apparatus for washing and disinfecting the interiors of trailers and vans having a boom structure having a washing head and disinfecting nozzle connected to the free end of the boom. The boom is connected to a fixed mounting structure having means for both raising and lowering the boom in the vertical direction as well as at various angles with respect to the horizontal. The washing head is secured to an extension member telescoped within the boom structure. The extension member is biased away from the boom structure and serves to absorb impact if the trailer is not stopped in time as the interior thereof is backed onto the boom and the washing head engages the closed end thereof. The washing head is also rotated to direct the washing fluid toward the closed end of the trailer upon engagement therewith and back toward the open end of the trailer as the trailer is driven away from the boom to thereby flush out debris.

Claim 3
Independent Claim
274 words
An apparatus for washing and disinfecting the interiors of trailers and vans having an open and closed end, said apparatus comprising: a. a vertically extending mounting structure fixed at one end and having two spaced-apart posts with first and second spaced-apart, horizontally disposed cross-members slidably positioned on said posts; b. a boom structure secured at one end to said mounting structure and extending in a substantially horizontal position, said boom structure having upper and lower hollow, elongated tubular boom members, one end of each of said boom members being connected together and the other end of said upper boom member being connected to said first cross-member and said other end of said lower boom member being connected to said second cross-member; c. means secured to said mounting structure for moving said boom structure to a plurality of vertical elevations to accommodate interiors of varying heights; d. means secured to said mounting structure for positioning and boom structure at a plurality of angles with respect to the horizontal; e. extension means slidably positioned in the free end of said boom structure; f. a source of washing fluid under pressure; and g. a washing head rotatably attached to said extension means and connected to said source of washing fluid, said washing head having spray forming means biased to direct said washing fluid generally downward and back toward said free end of said boom structure when said trailer is being freely backed onto and away from said boom structure and directed generally downward and away from said free end of said boom structure when said washing head is in engagement with said closed end of said trailer.
Claim 4
Independent Claim
274 words
An apparatus for washing and disinfecting the interiors of trailers and vans having an open and closed end, said apparatus comprising: a. a vertically extending mounting structure fixed at one end and having two spaced-apart posts with first and second spaced-apart, horizontally disposed cross-members slidably positioned on said posts; b. a boom structure secured at one end to said mounting structure and extending in a substantially horizontal position, said boom structure having upper and lower hollow, elongated tubular boom members, one end of each of said boom members being connected together and the other end of said upper boom member being connected to said first cross-member and said other end of said lower boom member being connected to said second cross-member; c. means secured to said mounting structure for moving said boom structure to a plurality of vertical elevations to accommodate interiors of varying heights; d. means secured to said mounting structure for positioning and boom structure at a plurality of angles with respect to the horizontal; e. extension means slidably positioned in the free end of said boom structure; f. a source of washing fluid under pressure; and g. a washing head rotatably attached to said extension means and connected to said source of washing fluid, said washing head having spray forming means biased to direct said washing fluid generally downward and back toward said free end of said boom structure when said trailer is being freely backed onto and away from said boom structure and directed generally downward and away from said free end of said boom structure when said washing head is in engagement with said closed end of said trailer.
Claim 5
Dependent Claim

An apparatus as set forth in claim 2 wherein said first cross-member is connected by cable to a winch means for raising and lowering said first and second croSs-members and said boom structure.
Claim 6
Dependent Claim
74 words
An apparatus as set forth in claim 2 wherein said first cross-member has horizontally extending, spaced-apart brace means secured thereto, a cross-bar positioned between said brace means and slidable thereon, said upper end of said tubular member being connected to said cross-bar, and means connected between said cross-bar and said first cross-member for moving said cross-bar relative to said cross-member to thereby position said boom structure at various angles with respect to the horizontal.
Claim 7
Dependent Claim
