Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
204 words
A throttle control for a prime mover comprising a prime mover throttle member, a hand control, a foot control, a combining device including a support member and a combining member slidable relative to the support member in first and second opposite directions, first linkage means connecting the combining member with the throttle member so that movement of the combining member in said first direction moves the throttle member towards a fully open position, bias means acting to bias the throttle member towards an idle position and hence bias said combining member in said second direction via the first linkage means, second linkage means connecting the foot control and combining member for movement of the combining member in said first direction, and third linkage means connecting the hand control with the combining member via a connection capable of moving the combining member in said first direction only and allowing sliding of the combining member in said first and second directions relative to the third linkage means, the arrangement being such that any throttle member position set by hand control can be increased using the foot control by said second linkage means sliding the combining member in said first direction relative to said third linakge means.
Claim 2
Dependent Claim
204 words
A throttle control for a prime mover comprising a prime mover throttle member, a hand control, a foot control, a combining device including a support member and a combining member slidable relative to the support member in first and second opposite directions, first linkage means connecting the combining member with the throttle member so that movement of the combining member in said first direction moves the throttle member towards a fully open position, bias means acting to bias the throttle member towards an idle position and hence bias said combining member in said second direction via the first linkage means, second linkage means connecting the foot control and combining member for movement of the combining member in said first direction, and third linkage means connecting the hand control with the combining member via a connection capable of moving the combining member in said first direction only and allowing sliding of the combining member in said first and second directions relative to the third linkage means, the arrangement being such that any throttle member position set by hand control can be increased using the foot control by said second linkage means sliding the combining member in said first direction relative to said third linakge means.
Claim 3
Dependent Claim
28 words
A control according to claim 1 in which the support member comprises a housing within which the combining member in the form of a slidable block is supported.
Claim 4
Dependent Claim
18 words
A control according to claim 2 in which the housing and slidable block are made from plastics material.
Claim 5
Dependent Claim
22 words
A control according to claim 1 in which each linkage means includes a Bowden cable to permit easy installation of the control.
Claim 6
Dependent Claim
54 words
A control according to claim 4 in which the support member comprises a housing within which the combining member in the form of a slidable block is supported and in which the outer of each cable is held captive by the housing and the inner of each cable is connected with the slidable block.
Claim 7
Dependent Claim
80 words
A control according to claim 5 in which the slidable block is provided with three slots which extend end to end of the block in directions parallel to said first and second directions, each slot being arranged to receive a respective Bowden cable inner loosely slidable therein and each inner being connected with the block by abutment of a nipple thereon with a respective end face of the block to transmit motion to the block by tension of the inner.
