Abstract
Abstract A torque release adapter in which the torque at which release is effected is controlled by variable spring pressure applied axially with respect to the rotational force applying the torque; characterized in that the adjusted torque at which release takes place is unaffected by the application of axial force to the device applied in conjunction with the rotational force.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
141 words
A torque release adapter for applying rotational force up to a predetermined maximum, comprising shafts supported in coaxial alignment, a part on one shaft yieldably held engaged with a part of the other shaft, said part on the one shaft comprising an annular ring mounted on the one shaft in confronting relation to the part on the other shaft, said annular ring being operably connected to the one shaft to partake of the rotation thereof but being permitted to move axially thereon, said annular ring and said other part containing peripherally spaced recesses between which are mounted balls for transmitting rotation of the annular ring to said other part, and means for adjustably applying said yielding engagement between the annular ring and said other part to control relative rotation of the part independently of the axial pressure applied to the shafts.
Claim 2
Dependent Claim
141 words
A torque release adapter for applying rotational force up to a predetermined maximum, comprising shafts supported in coaxial alignment, a part on one shaft yieldably held engaged with a part of the other shaft, said part on the one shaft comprising an annular ring mounted on the one shaft in confronting relation to the part on the other shaft, said annular ring being operably connected to the one shaft to partake of the rotation thereof but being permitted to move axially thereon, said annular ring and said other part containing peripherally spaced recesses between which are mounted balls for transmitting rotation of the annular ring to said other part, and means for adjustably applying said yielding engagement between the annular ring and said other part to control relative rotation of the part independently of the axial pressure applied to the shafts.
Claim 3
Dependent Claim
33 words
Apparatus according to claim 1, wherein said ring contains at its inner face and the shaft at its outer face recesses containing balls, said balls transmitting rotation of the shaft to the ring.
Claim 4
Dependent Claim
14 words
Apparatus according to claim 2, wherein the recesses in the shaft are axially elongate.
Claim 5
Dependent Claim
20 words
Apparatus according to claim 3, wherein the end of the shaft contains a peripheral groove for receiving a spring ring.
