Abstract
Abstract A relay and a relay-adder combination incorporating a constant force actuating arrangement allowing for the use of the same coil in both configurations whereby a reaction force which is encountered in the actuation of the relay per se is bypassed in the actuation of the relay-adder combination and is replaced by the force which is encountered in the actuation of the adder and which is equal to the reaction force.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
225 words
A constant actuating force arrangement for a relay and a relay-adder combination comprising: a relay housing including fixed contacts; a magnetic frame and a coil supported by said housing; a moving contact carrier-armature assembly arranged to be guided for actuating and deactuating movement by said housing under the influence of said frame and said coil so as to change the condition of the relay switch poles formed by the corresponding fixed and moving contacts; bias means associated with said housing and said assembly whereby actuating movement of said assembly normally results in a reaction force being provided by said bias means which opposes the actuating movement; an adder housing including fixed contacts for association with said relay housing; a moving contact carrier arranged to be guided for actuating and deactuating movement by said adder housing and arranged to be associated with said assembly so as to be moved therewith to change the condition of the adder switch poles formed by the corresponding fixed and moving contacts; and bypass means for utilization when the adder is associated with the relay and positionable with respect to said bias means so that the reaction force does not arise, the reaction force provided by said bias means being chosen to equal the additional actuating force necessary to provide the actuating movement for said moving contact carrier of the adder.
Claim 2
Dependent Claim
225 words
A constant actuating force arrangement for a relay and a relay-adder combination comprising: a relay housing including fixed contacts; a magnetic frame and a coil supported by said housing; a moving contact carrier-armature assembly arranged to be guided for actuating and deactuating movement by said housing under the influence of said frame and said coil so as to change the condition of the relay switch poles formed by the corresponding fixed and moving contacts; bias means associated with said housing and said assembly whereby actuating movement of said assembly normally results in a reaction force being provided by said bias means which opposes the actuating movement; an adder housing including fixed contacts for association with said relay housing; a moving contact carrier arranged to be guided for actuating and deactuating movement by said adder housing and arranged to be associated with said assembly so as to be moved therewith to change the condition of the adder switch poles formed by the corresponding fixed and moving contacts; and bypass means for utilization when the adder is associated with the relay and positionable with respect to said bias means so that the reaction force does not arise, the reaction force provided by said bias means being chosen to equal the additional actuating force necessary to provide the actuating movement for said moving contact carrier of the adder.
Claim 3
Dependent Claim
46 words
The arrangement of claim 1 wherein said bias means comprises a protrusion associated with one of said relay housing and said assembly and a resilient member associated with the other whereby said protrusion normally engages said resilient member upon actuating movement to provide the reaction force.
Claim 4
Dependent Claim
47 words
The arrangement of claim 2 wherein said bypass means is associated with said adder housing such that with the adder associated with the relay said bypass means positions one of said protrusion and said resilient member so as to preclude the normal engagement therebetween from taking place.
Claim 5
Dependent Claim
28 words
The arrangement of claim 3 wherein said protrusion is associated with said assembly and said resilient member is associated with said relay housing and comprises a spring-loaded lever.
Claim 6
Dependent Claim
56 words
The arrangement of claim 4 wherein the bypass means comprises screw fasteners provided in said adder housing which fasteners are arranged to secure said relay housing and said adder housing together and are further arranged to engage and position said spring loaded lever so as to preclude the normal engagement with said protrusion from taking place.
