Abstract
Abstract A gear selector means for use with a transmission having a main change speed gear set (X) and one or more associated range change gear sets (Y, Z). The selector means includes a selector member (50) which is movable to a number of positions (1,2,3,4) for the selection of a number of change speed ratios of the transmission and which has a neutral position or series of positions (n) corresponding to a neutral condition of the transmission. The selector member is movable from the or a neutral position (n) to an «up» position (52) in which upward range changes can be made in a predetermined sequence (A, B, C, D) and to a «down position (53) in which downward range changes can be made in a predetermined sequence, each movement of the selector member to the «up» or «down» position being arranged to change the operative range of the transmission either up or down to the next range in the predetermined sequence.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
171 words
A gear selector means for use with a transmission having a main change speed gear (X) set and one or more associated range change gear sets (XY), the selector means including a selector member (50) which is movable to a number of positions (1, 2, 3, 4) for the selection of a number of change speed ratios of the transmission and which has a neutral position or series of positions (n) corresponding to a neutral condition of the transmission, the selector means being characterised in that the selector member (50) is movable from the or a neutral position to an "up" position (52) in which upward range changes can be made in a predetermined sequence (A, B, C, D) and to a "down" position (53) in which downward range changes can be made in a predetermined sequence, each movement of the selector member to said "up" or "down" position being arranged to change the operative range of the transmission either up or down to the next range in said predetermined sequence.
Claim 2
Dependent Claim
171 words
A gear selector means for use with a transmission having a main change speed gear (X) set and one or more associated range change gear sets (XY), the selector means including a selector member (50) which is movable to a number of positions (1, 2, 3, 4) for the selection of a number of change speed ratios of the transmission and which has a neutral position or series of positions (n) corresponding to a neutral condition of the transmission, the selector means being characterised in that the selector member (50) is movable from the or a neutral position to an "up" position (52) in which upward range changes can be made in a predetermined sequence (A, B, C, D) and to a "down" position (53) in which downward range changes can be made in a predetermined sequence, each movement of the selector member to said "up" or "down" position being arranged to change the operative range of the transmission either up or down to the next range in said predetermined sequence.
Claim 3
Dependent Claim
60 words
A gear selector means according to claim 1 characterised in that the selector member (50) has a neutral plane of movement (n) corresponding to a neutral condition of the transmission and the "up" and "down" positions (52, 53) are reached by further movement of the selector member in extensions of said neutral plane (n) at opposite ends of said plane.
Claim 4
Dependent Claim
69 words
A gear selector means according to claim 1 characterised in that the selector member (50) has a neutral plane of movement (n) corresponding to a neutral condition of the transmission and the "up" and "down" positions (52a, 53a, 52b, 53b) are reached from said neutral plane (n) by movement of the selector member (50) in opposite directions in a plane (J, K) at right angles to said neutral plane.
Claim 5
Dependent Claim
52 words
A gear selector means according to claim 2 characterised in that the selector member (50) is movable in an H-shaped shift pattern (51) to select at least some of the change speed ratios of the transmission, the crossbar of the H-shaped shift pattern providing the neutral plane (n) of the selector member.
Claim 6
Dependent Claim
80 words
A gear selector means according to claim 3 characterised in that the selector member (50) is movable in an H-shaped shift pattern (51) to select at least some of the change speed ratios of the transmission, the crossbar of the H pattern providing the neutral plane (n) of the selector member and the "up" and "down" positions (52a, 53a) being located in a plane (J) lying parallel to and inbetween the other two planes (1-2,3-4) of the H-shaped shift pattern.
Claim 7
Dependent Claim
81 words
A gear selector means according to claim 3 characterised in that the selector member (50) is movable in an H-shaped shift pattern (51) to select at least some of the change speed ratios of the transmission, the crossbar of the H pattern providing the neutral plane (n) of the selector member and the "up" and "down" positions (52b, 53b) being located in a plane (K) lying parallel to and outside the other two planes (1-2, 3-4) of the H-shaped shift pattern.
Claim 8
Dependent Claim
40 words
A gear selector means according to claim 1 characterised in that the selector member (50) operates switch means (106, 109) each time it is moved to the "up" or "down" position (52, 53) in order to initiate said range change.
Claim 9
Dependent Claim
42 words
A gear selector means according to claim 7 characterised in that the switch means (106, 109) initiates the operation of solenoid-operated fluid control valves (103, 104, 105) which in turn control the operation of hydraulically operated range change actuators (100, 101, 102).
Claim 10
Dependent Claim
33 words
A gear selector means according to claim 1 characterised in that the selector member (50) carries a forward/ reverse control member (50a) for initiating a change in the drive direction of the transmission.
