Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
103 words
In a torsional oscillating device, comprising an oscillating mass, a support for said mass which is connected thereto and a spring means connected to said mass for providing restoring force to said mass, the improvement comprising, said support for said mass comprising spaced apart support means and a torsional element which has a constant torsion characteristic and is carried by said spaced apart support means; said mass being firmly affixed to said element such that oscillation of said mass correspondingly oscillates said element and such that said spring means provides additional restoring force in addition to the restoring force provided by said element.
Claim 2
Dependent Claim
103 words
In a torsional oscillating device, comprising an oscillating mass, a support for said mass which is connected thereto and a spring means connected to said mass for providing restoring force to said mass, the improvement comprising, said support for said mass comprising spaced apart support means and a torsional element which has a constant torsion characteristic and is carried by said spaced apart support means; said mass being firmly affixed to said element such that oscillation of said mass correspondingly oscillates said element and such that said spring means provides additional restoring force in addition to the restoring force provided by said element.
Claim 3
Dependent Claim
19 words
In the torsional oscillating device of claim 1, the improvement further comprising, said element comprising an elongated elastic strip.
Claim 4
Dependent Claim
20 words
A device in accordance with claim 1 in which said spring means is a helical spring surrounding said torsional element.
Claim 5
Dependent Claim
28 words
A device in accordance with claim 1 in which said spring means comprises at least one spiral spring arranged on at least one side of said oscillating mass.
Claim 6
Dependent Claim
36 words
A device in accordance with claim 1 in which said torsional element has a characteristic so as to provide a restoring force of less than 1 percent of the restoring force provided by said spring means.
