Hydraulic powered handwasher

Claim 1

A fluid energized washing device for cleaning the terminal end of an elongated member, comprising in combination: means for providing a stream of fluid under pressure; fluid energized motor means for providing rotational power, said motor means activated by said stream of liquid under pressure, said motor means having in combination means defining a vented casing, vented to ambient having an inner wall section in the form of a reaction ring, means defining a piston blockhaving a plurality of equi-length radially disposed piston chambers radially interconnected to a central axial bore, means defining a piston for each of said piston chambers, means for directing fluid under pressure selectively into each of said piston chambers in outwardly urging relationship to said piston and for selectively and sequentially directing the flow of said fluid from each of said piston chambers to an exit means in response to inward urging of said piston, any said fluid under pressure escaping past a said piston being vented to ambient independent of said means for directing fluid under pressure to maintain the space between said piston block and said reaction ring substantially free of said fluid, means mounting said piston block in said casing and means for constraining one of said piston block and said reaction ring from rotational motion whereby rotational motion is developed between said piston block and said reaction ring provided at least one said piston is in urging relationship with said reaction ring; means defining a laving member rotationally driven by said motor means wherein said laving member is a hollow conduit driveably rotatably mounted on said motor means having laving elements mounted along the inner wall thereof; means for interacting said stream of fluid after said stream of fluid has exited through said exit means with said laving member so as to wet said laving member, said means for interacting comprising a hollow conduit having radially directed outlets; means for facilitating the contacting of said terminal-end portion of said elongated member with said laving member in a laving relationship; housing means for enclosing and supporting said motor means and said laving means, said housing means including a drain for fluid collected therein and an access opening adapted to the insertion therethrough of at least the terminal-end portion of the elongated member to contact said laving means; and, base means for supporting said housing means on an extended surface.
