Abstract
Abstract An improved spray means is provided which includes a telescopic tubular boom and nozzle assembly mounted on a light-weight twowheeled carriage adapted to be maneuvered about by one person. A spring-loaded hose reel is mounted of the carriage at the base end of the boom assembly to function generally in the manner of a counterweight, and to supply liquid to the nozzle. A hand-wound cable reel is provided with three cables, one for actuating the nozzle, one to give stability to the extended boom, and one to extend the boom from its retracted condition.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
239 words
A spray assembly adapted to be manually maneuverable for discharging a fluid stream into an elevated relatively inaccessible location, comprising a two-wheeled carriage means, a first tubular member mounted in boom-like manner on said carriage means to be elevated and depressed by pivotal movement of said carriage means on its wheels, a second tubular member at least partially inserted in said first tubular means and outwardly slidable therein away from said carriage means, a third tubular means at least partially inserted in said second tubular means and outwardly slidable therein away from said carriage means, a normally closed nozzle means mounted on the end of said third tubular member opposite said carriage means, a flexible hose slidably disposed in said third tubular member and having its discharge end connected to said nozzle means and its receiving end located adjacent said carriage means, a first bracing cable interconnected to maintain the relative rigidity of said tubular members when extended one out of anOther in boom-like manner, a second nozzle-actuating cable extending along said tubular members and connected to said nozzle means, a third boom-control cable interconnected with said tubular members, and a single cable reel means interconnected with said first, second and third cables for winding in said third cable and drawing said second tubular member from said first tubular member and said third tubular member from said second tubular member while synchronously paying out said first and second cables.
Claim 2
Dependent Claim
239 words
A spray assembly adapted to be manually maneuverable for discharging a fluid stream into an elevated relatively inaccessible location, comprising a two-wheeled carriage means, a first tubular member mounted in boom-like manner on said carriage means to be elevated and depressed by pivotal movement of said carriage means on its wheels, a second tubular member at least partially inserted in said first tubular means and outwardly slidable therein away from said carriage means, a third tubular means at least partially inserted in said second tubular means and outwardly slidable therein away from said carriage means, a normally closed nozzle means mounted on the end of said third tubular member opposite said carriage means, a flexible hose slidably disposed in said third tubular member and having its discharge end connected to said nozzle means and its receiving end located adjacent said carriage means, a first bracing cable interconnected to maintain the relative rigidity of said tubular members when extended one out of anOther in boom-like manner, a second nozzle-actuating cable extending along said tubular members and connected to said nozzle means, a third boom-control cable interconnected with said tubular members, and a single cable reel means interconnected with said first, second and third cables for winding in said third cable and drawing said second tubular member from said first tubular member and said third tubular member from said second tubular member while synchronously paying out said first and second cables.
Claim 3
Dependent Claim
33 words
The assembly described in claim 1, wherein said first and second cables are wound in one direction onto said cable reel means and said third cable is wound in the opposite direction thereon.
Claim 4
Dependent Claim
42 words
The assembly described in claim 2, further comprising a hose reel means rotatably mounted on said first tubular member perpendicularly and oppositely to said tubular members, said receiving end of said hose being wound at least partially about said hose reel means.
Claim 5
Dependent Claim
31 words
The assembly described in claim 3, wherein said cable reel means is provided with three separate drum portions each being windably interconnected with a different respective one of said three cables.
Claim 6
Dependent Claim
77 words
The assembly described in claim 4, further comprising a first upright support member mounted on said carriage means adjacent one of its wheels and presenting a handhold portion at substantially a shoulder-high elevation, and a second upright support member mounted on said carriage means adjacent the other of its wheels and also presenting a handhold portion at substantially a shoulder-high elevation, said cable reel means being rotatably mounted between said upright support members adjacent said handhold portions.
Claim 7
Dependent Claim
36 words
The assembly described in claim 5, further comprising actuating means interconnected between said nozzle means and said second cable and adapted to open said nozzle means in response to a preselected tension in said second cable.
Claim 8
Dependent Claim
58 words
The assembly described in claim 6, wherein said carriage means further includes a U-shaped channel member slidably disposed about the end of said first tubular member adjacent said carriage means and having upwardly thrust side portions, and locking means interconnected with said channel member for clamping said side portions thereof into gripping engagement with said first tubular member.
Claim 9
Dependent Claim
36 words
The assembly described in claim 7, wherein said locking means includes bolt means inserted perpendicularly through said upwardly thrust side portions of said channel member and above said slidably inserted end of said first channel member.
Claim 10
Dependent Claim
38 words
The assembly described in claim 8 wherein said hose reel is spring-loaded to wind on said hose during retraction of said third tubular member into said second tubular member and said second member into said first tubular member.
Claim 11
Dependent Claim
220 words
The assembly described in claim 9, wherein said second tubular member is provided with a slot-like wall aperture, wherein said first cable is wound in one direction onto one of said drum portions of said cable reel means and having its other end slidably extended along the extended end of said first tubular member and fastened to said third tubular member adjacent said nozzle means, wherein said second cable is wound in said same one direction onto another different one of said drum portions of said cable reel means and having its other end fastened to said actuating means, and wherein said third cable is wound in the opposite direction onto a third different one of said drum portions of said cable reel means and having its other end threaded into said extended end of said first tubular member to and into the near inserted end of said second tubular member and thence through said aperture therein for extension along the exterior of and into the further end of said second tubular member, said other end of said third cable being further threaded in a reverse manner back into said second tubular member and along the exterior sUrface of said third tubular member and fixedly secured to the inserted near end of said third tubular member opposite said nozzle means.
