Abstract
Abstract A flexible force transmitting member biasing arrangement consisting of a snubbing device and a spring. The arrangement functions to permit a flexible force transmitting member attached to it to undergo a significant amount of movement (due to the force exerted by the spring) at very slow rates but prevents the flexible force transmitting member from undergoing substantial movement at high rates attendant with high frequencies of motion. A preferred form of the snubbing device is a dashpot.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
104 words
In an apparatus including a flexible force transmitting member and a stationary member, characterized in that an end of the flexible force transmitting member is connected to the stationary member by connector apparatus which maintains a substantially constant tension on said flexible force transmitting member, said connector apparatus consisting of a snubbing device containing a high viscosity material and a spring, the snubbing device being connected between the spring and the flexible force transmitting member such that the spring exerts a force along the length of said force transmitting member at all times whereby the tension on said force transmitting member remains substantially constant.
Claim 2
Dependent Claim
104 words
In an apparatus including a flexible force transmitting member and a stationary member, characterized in that an end of the flexible force transmitting member is connected to the stationary member by connector apparatus which maintains a substantially constant tension on said flexible force transmitting member, said connector apparatus consisting of a snubbing device containing a high viscosity material and a spring, the snubbing device being connected between the spring and the flexible force transmitting member such that the spring exerts a force along the length of said force transmitting member at all times whereby the tension on said force transmitting member remains substantially constant.
Claim 3
Dependent Claim
119 words
In an apparatus including a flexible force transmitting member and a stationary member, characterized in that an end of the flexible force transmitting member is connected to the stationary member by means which maintains a substantially constant tension on said flexible force transmitting member, said means including a high viscosity material-containing snubbing device and a spring, said snubbing device coupling said spring to said flexible force transmitting member, said means functioning (1) as a soft connector in relation to slow rates of movement of the flexible force transmitting member and (2) as a rigid connector in relation to rapid rates of movement of the flexible force transmitting member, whereby the tension on said force transmitting member remains substantially constant.
Claim 4
Dependent Claim
119 words
In an apparatus including a flexible force transmitting member and a stationary member, characterized in that an end of the flexible force transmitting member is connected to the stationary member by means which maintains a substantially constant tension on said flexible force transmitting member, said means including a high viscosity material-containing snubbing device and a spring, said snubbing device coupling said spring to said flexible force transmitting member, said means functioning (1) as a soft connector in relation to slow rates of movement of the flexible force transmitting member and (2) as a rigid connector in relation to rapid rates of movement of the flexible force transmitting member, whereby the tension on said force transmitting member remains substantially constant.
Claim 5
Dependent Claim
99 words
In an apparatus including a flexible force transmitting member and a stationary member, characterized in that an end of the flexible force transmitting member is connected to the stationary member by means which maintains a substantially constant tension on said flexible force transmitting member, said means including a high viscosity material-containing snubbing device and a spring, said snubbing device coupling said spring to said flexible force transmitting member, said means functioning to permit the end of the flexible force transmitting member to undergo low rates of movement but not high rates of movement whereby said constant tensioning is achieved.
Claim 6
Dependent Claim
99 words
