Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
103 words
A multiple contact gauge for controlling a plurality of electrical circuits of the type which includes an indicator hand and a transparent cover overlying the hand comprising a plurality of contact arms mounted on said transparent cover for establishing said circuits; a resilient contact member mounted on said indicator hand; and means for swinging said multiple contact arms into and out of the path of travel of said resilient contact member on said indicator hand whereby selected ones of said electric circuits may be established upon contact of said contact member of said hand with selected ones of said plurality of contact arms.
Claim 2
Dependent Claim
103 words
A multiple contact gauge for controlling a plurality of electrical circuits of the type which includes an indicator hand and a transparent cover overlying the hand comprising a plurality of contact arms mounted on said transparent cover for establishing said circuits; a resilient contact member mounted on said indicator hand; and means for swinging said multiple contact arms into and out of the path of travel of said resilient contact member on said indicator hand whereby selected ones of said electric circuits may be established upon contact of said contact member of said hand with selected ones of said plurality of contact arms.
Claim 3
Dependent Claim
54 words
A device as claimed in claim 1 wherein the means for swinging said contact arms comprises a shaft extending through said transparent cover with said contact arm secured to the lower end of said shaft; and a knob attached to the upper end of said shaft for rotating said shaft and said contact arm.
Claim 4
Dependent Claim
121 words
A device as claimed in claim 1 wherein said resilient contact on said indicator hand includes a shaft having its opposite end secured to said hand; a coil spring encompassing said shaft and having one end anchored to said hand; and a contact post secured to the opposite end of said coil spring and extending perpendicularly upwardly from said hand. 4. A device as claimed in claim 2 wherein said resilient contact on said indicator hand includes a shaft having its opposite end secured to said hand; a coil spring encompassing said shaft and having one end anchored to said hand; and a contact post secured to the opposite end of said coil spring and extending perpendicularly upwardly from said hand.
Claim 5
Dependent Claim
36 words
A device as claimed in claim 4 wherein said contact arm slopes inwardly and downwardly away from said transparent cover to provide clearance to permit swinging of said contact arms without interference with adjacent contact arms.
