Abstract
Abstract An anti-capsizing warning system for vehicles comprising a sending unit mounted to the frame of the vehicle adjacent an axle thereof for completing an electrical circuit to energize a warning device disposed near the operator of the vehicle in response to an increase in the spacing between the axle and the frame of the vehicle beyond a predetermined level. The sending unit may preferably comprise one or more lever actuated microswitches and a flexible member or cable interconnecting the actuating lever of the microswitches and the axle. A second sending unit may be placed at the other end of the axle, and may be wired in parallel with the first sending unit, so that the warning device will be suitably actuated in response to the tipping of the vehicle in either direction.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
91 words
An anti-capsizing warning system for a vehicle having spring mounted wheels, the spring mounting of at least one of said wheels on each side of said vehicle being independent of the other wheels on the same one side of said vehicle, comprising first sending means for producing an electrical signal solely in response to an increase in the spacing between the frame of said vehicle and one of said at least one wheels of said vehicle beyond a predetermined level and an electrically operated warning device responsive to said electrical signal.
Claim 2
Dependent Claim
91 words
An anti-capsizing warning system for a vehicle having spring mounted wheels, the spring mounting of at least one of said wheels on each side of said vehicle being independent of the other wheels on the same one side of said vehicle, comprising first sending means for producing an electrical signal solely in response to an increase in the spacing between the frame of said vehicle and one of said at least one wheels of said vehicle beyond a predetermined level and an electrically operated warning device responsive to said electrical signal.
Claim 3
Dependent Claim
49 words
Apparatus according to claim 1 wherein said first sending means comprises a lever actuated microswitch mounted to the frame of said vehicle adjacent the end of the axle of said vehicle associated with said wheel and a flexible member connecting the actuating lever of said microswitch and said axle.
Claim 4
Dependent Claim
63 words
Apparatus according to claim 1 comprising second sending means for producing an electrical signal in response to an increase in the spacing between the frame of said vehicle and another of said at least one wheels of said vehicle electrically connected in parallel with said first sending means, said another wheel being at the opposite end of the axle carrying said one wheel.
Claim 5
Dependent Claim
91 words
An anti-capsizing warning system for a vehicle having spring mounted wheels, the spring mounting of at least one of said wheels on each side of said vehicle being independent of the other wheels on the same one side of said vehicle, comprising first sending means for producing an electrical signal solely in response to an increase in the spacing between the frame of said vehicle and one of said at least one wheels of said vehicle beyond a predetermined level and an electrically operated warning device responsive to said electrical signal.
Claim 6
Dependent Claim
91 words
An anti-capsizing warning system for a vehicle having spring mounted wheels, the spring mounting of at least one of said wheels on each side of said vehicle being independent of the other wheels on the same one side of said vehicle, comprising first sending means for producing an electrical signal solely in response to an increase in the spacing between the frame of said vehicle and one of said at least one wheels of said vehicle beyond a predetermined level and an electrically operated warning device responsive to said electrical signal.
Claim 7
Dependent Claim
71 words
Apparatus according to claim 4 wherein said first sending means comprises a plurality of lever actuated microswitches mounted to the frame of said vehicle adjacent the end of the axle of said vehicle associated with said wheel, said microswitches having a common actuaTing lever, said microswitches being adapted to actuate upon varying degrees of pivotal movement of said actuating lever, and a flexible member connecting said actuating lever and said axle.
Claim 8
Dependent Claim
29 words
Apparatus according to claim 5 wherein said warning means comprises a plurality of electrically-operated warning devices, each of said warning devices being electrically connected to one of said microswitches.
Claim 9
Dependent Claim
70 words
Apparatus according to claim 4 wherein said first sending means comprise a pair of lever-actuated microswitches mounted to the frame of said vehicle adjacent the end of the axle of said vehicle associated with said wheel, said microswitches having a common actuating lever, said microswitches being adapted to actuate upon different degrees of pivotal movement of said actuating lever, and a flexible member connecting said actuating lever and said axle.
Claim 10
Dependent Claim
27 words
Apparatus according to claim 7 wherein said warning means comprises a pair of electrically-operated warning devices, each of which is electrically connected to one of said microswitches.
Claim 11
Dependent Claim
62 words
Apparatus according to claim 4 comprising second sending means for producing electrical signals in response to an increase in the spacing between the frame of said vehicle and another of said at least one wheels of said vehicle electrically connected in parallel with said first sending means, said another wheel being at the opposite end of the axle carrying said one wheel.
