Abstract
Abstract An apparatus for spray washing the interior of vessels includes a body member secured to a fluid supply line, and a housing rotatably secured to the body and in flow communication therewith. A hub is rotatably secured to the housing on an axis transverse to the body-housing axis, and a plurality of nozzles extend radially from the hub perpendicular to the hub axis. A pair of reaction jets also extend radially from the hub to drive the hub in an oscillating motion. The hub is secured to a spindle which is joined to a lever which operates an over center toggle. The toggle operates a valve which alternates the fluid flow to the reaction jets to produce the oscillating hub motion. The lever also drives a ratchet mechanism which incrementally rotates the housing about the body member.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
228 words
A washing device using cleansing liquid under pressure, comprising a spindle means rotatably secured in a housing and having a liquid flow channel therethrough, nozzle means extending from said spindle means for spraying said liquid, reaction jet means, extending from said spindle means, for emitting at least one stream of liquid and driving said spindle means in a rotational motion, valve means for selectively permitting liquid flow to said reaction jet means, said valve means including a valve shaft extending coaxially within said spindle means and freely rotating therein, and a valve member secured on said valve shaft adjacent to said reaction jet means and including flow ports extending therethrough from said liquid flow channel of said spindle means to said reaction jet means, arbor means rotatably secured within said housing and including a liquid flow passage connecting a source of said liquid under pressure to said liquid flow channel, switch means for controlling said valve means, said switch means including a toggle arm extending from said valve shaft, a spindle arm extending from said spindle means adjacent to said toggle arm and rotatable about a common axis, first linking means joining said toggle arm and said spindle arm in an over-center toggle fashion, and second linking means extending between said spindle means and said arbor means for driving said housing in rotational motion about said arbor means.
Claim 2
Dependent Claim
228 words
A washing device using cleansing liquid under pressure, comprising a spindle means rotatably secured in a housing and having a liquid flow channel therethrough, nozzle means extending from said spindle means for spraying said liquid, reaction jet means, extending from said spindle means, for emitting at least one stream of liquid and driving said spindle means in a rotational motion, valve means for selectively permitting liquid flow to said reaction jet means, said valve means including a valve shaft extending coaxially within said spindle means and freely rotating therein, and a valve member secured on said valve shaft adjacent to said reaction jet means and including flow ports extending therethrough from said liquid flow channel of said spindle means to said reaction jet means, arbor means rotatably secured within said housing and including a liquid flow passage connecting a source of said liquid under pressure to said liquid flow channel, switch means for controlling said valve means, said switch means including a toggle arm extending from said valve shaft, a spindle arm extending from said spindle means adjacent to said toggle arm and rotatable about a common axis, first linking means joining said toggle arm and said spindle arm in an over-center toggle fashion, and second linking means extending between said spindle means and said arbor means for driving said housing in rotational motion about said arbor means.
