Abstract
Abstract A rotary to linear tool attachment adapted to be secured to an underwater power tool so as to enable a rotary output shaft of the tool to drive a reciprocating output shaft of the adapter. Specifically, the adapter enables the rotary output shaft of a power tool to drive rotary saws, chippers, descalers or hammers for underwater applications.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
291 words
A rotary to linear converter for use in combination with an underwater portable power tool having a driven rotary output shaft and a flat mounting face normal to the axis of said shaft, said tool having a spaced pair of prong receiving apertures extending into said front face and a movable locking element having an axis parallel to said front face located in a plane to intersect at least one of said apertures, said converter comprising a housing having a flat rear wall adapted to be secured in juxtaposition to said mounting face of said tool, said housing having a pair of spaced prongs extending rearwardly from said rear wall and adapted to be received in said apertures of said mounting face and to be locked thereon by movement of said locking element into engagement with a notch of at least one of said prongs, at least one water flow port in said housing to permit the ingress and egress of lubricating and cooling water flow through said housing, a barrel element rotatably mounted within said housing, a sleeve element surrounding said barrel, one of said barrel and sleeve elements having a continuous spiral cam groove in the periphery thereof, connector means for drivingly connecting one of said elements to said output shaft of said tool, cam follower means secured to one of said elements and extending into said cam groove of the other element, a key and keyway operable between one of said elements and said housing to prevent rotation of said element relative to said housing, reciprocable output shaft means extending forwardly from the front of said sleeve, and means on the forward end of said reciprocatable output shaft for interchangeably connecting reciprocatable tools to said reciprocatable output shaft.
Claim 2
Dependent Claim
291 words
A rotary to linear converter for use in combination with an underwater portable power tool having a driven rotary output shaft and a flat mounting face normal to the axis of said shaft, said tool having a spaced pair of prong receiving apertures extending into said front face and a movable locking element having an axis parallel to said front face located in a plane to intersect at least one of said apertures, said converter comprising a housing having a flat rear wall adapted to be secured in juxtaposition to said mounting face of said tool, said housing having a pair of spaced prongs extending rearwardly from said rear wall and adapted to be received in said apertures of said mounting face and to be locked thereon by movement of said locking element into engagement with a notch of at least one of said prongs, at least one water flow port in said housing to permit the ingress and egress of lubricating and cooling water flow through said housing, a barrel element rotatably mounted within said housing, a sleeve element surrounding said barrel, one of said barrel and sleeve elements having a continuous spiral cam groove in the periphery thereof, connector means for drivingly connecting one of said elements to said output shaft of said tool, cam follower means secured to one of said elements and extending into said cam groove of the other element, a key and keyway operable between one of said elements and said housing to prevent rotation of said element relative to said housing, reciprocable output shaft means extending forwardly from the front of said sleeve, and means on the forward end of said reciprocatable output shaft for interchangeably connecting reciprocatable tools to said reciprocatable output shaft.
Claim 3
Dependent Claim
263 words
A rotary to linear converter for use on an underwater portable power tool having a driven rotary output shaft and a flat mounting face normal to the axis of said shaft, said tool having a spaced pair of prong receiving apertures extending into said front face and a movable locking element having an axis parallel to said front face located in a plane to intersect at least one of said apertures, said converter comprising a housing having a flat rear wall adapted to be secured in juxtaposition to said mounting face of said tool, said housing having a pair of spaced prongs extending rearwardly from said mounting face and to be locked thereon by movement of said locking element into engagement with a notch of at least one of said prongs, at least one water flow port in said housing to permit the flow of water throughout the interior of said housing to cool and lubricate said converter, a barrel cam having a continuous spiral cam groove in the periphery thereof, connector means for drivingly connecting said barrel cam to said output shaft of said tool, a sleeve surrounding said barrel cam, cam follower means secured to said sleeve and extending into said cam groove of said barrel cam, a key and keyway operable between said sleeve and said housing to prevent rotation of said sleeve relative to said housing, reciprocatable output shaft means extending forwardly from the front of said sleeve, and means on the forward end of said reciprocatable output shaft for interchangeably connecting reciprocatable tools to said reciprocatable output shaft.
Claim 4
Dependent Claim
263 words
A rotary to linear converter for use on an underwater portable power tool having a driven rotary output shaft and a flat mounting face normal to the axis of said shaft, said tool having a spaced pair of prong receiving apertures extending into said front face and a movable locking element having an axis parallel to said front face located in a plane to intersect at least one of said apertures, said converter comprising a housing having a flat rear wall adapted to be secured in juxtaposition to said mounting face of said tool, said housing having a pair of spaced prongs extending rearwardly from said mounting face and to be locked thereon by movement of said locking element into engagement with a notch of at least one of said prongs, at least one water flow port in said housing to permit the flow of water throughout the interior of said housing to cool and lubricate said converter, a barrel cam having a continuous spiral cam groove in the periphery thereof, connector means for drivingly connecting said barrel cam to said output shaft of said tool, a sleeve surrounding said barrel cam, cam follower means secured to said sleeve and extending into said cam groove of said barrel cam, a key and keyway operable between said sleeve and said housing to prevent rotation of said sleeve relative to said housing, reciprocatable output shaft means extending forwardly from the front of said sleeve, and means on the forward end of said reciprocatable output shaft for interchangeably connecting reciprocatable tools to said reciprocatable output shaft.
Claim 5
Dependent Claim
