Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
78 words
A prime mover assembly comprising a prime mover and a control therefor, said control having a lever movable in a first plane to vary the rotational speed of said prime mover and movable in a second plane to stop said prime mover, and wherein guide means are provided to guide said lever in said first plane and to permit movement in said second plane only when said lever is in a position corresponding to a minimum rotational speed.
Claim 2
Dependent Claim
78 words
A prime mover assembly comprising a prime mover and a control therefor, said control having a lever movable in a first plane to vary the rotational speed of said prime mover and movable in a second plane to stop said prime mover, and wherein guide means are provided to guide said lever in said first plane and to permit movement in said second plane only when said lever is in a position corresponding to a minimum rotational speed.
Claim 3
Dependent Claim
68 words
An assembly according to claim 1 in which the prime mover is a diesel engine having a fuel pump provided with a speed control and a stop control said lever being connected with said speed and stop controls by separate linkages so that movement of said lever in one of said planes operates said speed control and movement in the other of said planes operates the stop control.
Claim 4
Dependent Claim
73 words
An assembly according to claim 1 in which the lever carries a first actuating arm connected to one of said speed and stop controls by a linkage including a ball joint whose centre lies on said further axis, and the pivotting block carries a second actuating arm connected to the other of said speed and stop controls by a further linkage including a further ball joint whose centre lies on said one axis.
