Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
88 words
A lever-operated control apparatus comprising: two shafts, said shafts supported transverse to each other, the shafts connected to drive control devices, a lever supported to rotate in a first plane normal to one shaft and in a plane in the direction of the one shaft; and two spring elements connecting the lever and the shafts, said spring elements being the only members coupling control movement from the lever to the shafts, said spring elements maintaining the lever in a neutral position when said lever is not being rotated.
Claim 2
Dependent Claim
88 words
A lever-operated control apparatus comprising: two shafts, said shafts supported transverse to each other, the shafts connected to drive control devices, a lever supported to rotate in a first plane normal to one shaft and in a plane in the direction of the one shaft; and two spring elements connecting the lever and the shafts, said spring elements being the only members coupling control movement from the lever to the shafts, said spring elements maintaining the lever in a neutral position when said lever is not being rotated.
Claim 3
Dependent Claim
43 words
A lever-operated control apparatus as claimed in claim 1 wherein said spring elements comprise coil springs by which the lever is connected to each shaft so that the springs, each in the plane in the direction of a connected shaft center the lever.
Claim 4
Dependent Claim
30 words
A lever-operated control apparatus as claimed in claim 1, wherein the coil springs have longitudinal axes at least proximately intersect an extension of the connected shaft of the other spring.
