Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
81 words
Apparatus for converting fluid pressure pulses to mechanical motion comprising: a thin ribbon-like resilient member of substantial width arranged in a closely wound spiral to form a generally cylindrical body; thrust means mounted on the radially inner convolution of said resilient member; means supporting the radially outer convolution of said resilient member; and means for applying pressured air to one axial end of said body to cause the body to elongate axially with the convolutions thereof sliding axially along each other.
Claim 2
Dependent Claim
81 words
Apparatus for converting fluid pressure pulses to mechanical motion comprising: a thin ribbon-like resilient member of substantial width arranged in a closely wound spiral to form a generally cylindrical body; thrust means mounted on the radially inner convolution of said resilient member; means supporting the radially outer convolution of said resilient member; and means for applying pressured air to one axial end of said body to cause the body to elongate axially with the convolutions thereof sliding axially along each other.
Claim 3
Dependent Claim
26 words
The apparatus described in claim 1 wherein: said thrust means includes a plug portion disposed in substantially sealing cooperation with the inner convolution of said spiral.
Claim 4
Dependent Claim
90 words
A fluid-pressure operated thrusting and rotating device, comprising: an operating mechanism in the form of a spirally-wound band of thin ribbon-like resilient material, said band having a plurality of turns concentrically nested in repose to define a generally cylindrical body and including an inner turn and an outer turn; thrust means mounted on said inner turn; means supporting said outer turn; and means for applying fluid pressure to one axial end of said body to cause the body to elongate axially with the turns thereof sliding axially along each other.
Claim 5
Dependent Claim
90 words
A fluid-pressure operated thrusting and rotating device, comprising: an operating mechanism in the form of a spirally-wound band of thin ribbon-like resilient material, said band having a plurality of turns concentrically nested in repose to define a generally cylindrical body and including an inner turn and an outer turn; thrust means mounted on said inner turn; means supporting said outer turn; and means for applying fluid pressure to one axial end of said body to cause the body to elongate axially with the turns thereof sliding axially along each other.
