Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 140 words
A mechanical two-position panel indicator comprising: a support arranged to be mounted on a panel; a two-posiTion indicating member carried by said support so as to be visible from the front of the panel with the indicator associated therewith; said two-position indicating member being movable alternately between the two positions by a two-position mechanism capable of providing snap action associated in driving relation therewith to separately exhibit two distinct signals carried by said indicating member; said two-position mechanism carried by said support, positionable by a motor driver also carried by said support and incorporating an overcenter spring system having a selective adjustment means movable to at least two positions with respect to said overcenter spring system so as to vary the return force inherent therein and provide maintained and/or momentary conditions thereof and of said indicating member in its excursions.
Claim 2
Dependent Claim 140 words
A mechanical two-position panel indicator comprising: a support arranged to be mounted on a panel; a two-posiTion indicating member carried by said support so as to be visible from the front of the panel with the indicator associated therewith; said two-position indicating member being movable alternately between the two positions by a two-position mechanism capable of providing snap action associated in driving relation therewith to separately exhibit two distinct signals carried by said indicating member; said two-position mechanism carried by said support, positionable by a motor driver also carried by said support and incorporating an overcenter spring system having a selective adjustment means movable to at least two positions with respect to said overcenter spring system so as to vary the return force inherent therein and provide maintained and/or momentary conditions thereof and of said indicating member in its excursions.
Claim 3
Dependent Claim 33 words
The arrangement of claim 1 wherein the support member is a housing enclosing said indicating member, said two-position mechanism and said motor and wherein the adjustment means is accessible from outside said housing.
Claim 4
Dependent Claim 94 words
The arrangement of claim 2 wherein the two-position mechanism incorporates a toggle overcenter spring system of the two-element type including a first element pivoted on said housing for driving said indicating member and a second element for providing the overcenter snap action having a first extremity fastened to said first element and the second extremity pivoted on said housing, one of said elements being in tension and the other in compression and wherein said adjustment means includes one of said pivotal connections arranged for selective adjustment with respect to the remainder of the indicator.
Claim 5
Dependent Claim 84 words
The arrangement of claim 3 wherein the pivotal connection arranged for selective adjustment is that between the second extremity of said second element and said housing and wherein the adjustment means further includes a rod associated with the second extremity of said second element and spaced depressions in said housing to accommodate said rod, movement of said rod against the spring force of said second element from one depression to another providing for change in said indicating member between the maintained and momentary conditions.
Claim 6
Dependent Claim 52 words
The arrangement of claim 4 wherein said indicating member is in the form of a pivoted spherical element type, said two-position mechanism includes a compression lever as the first element and a tension coil spring as the second element, and said motor is in the form of a double-acting fluid pressure-operated device.
