Abstract
Abstract A potentiometer having a cover of conductive material formed by molding in a single piece with a pair of lateral terminals provided to be placed at the ends of a resistance track, a collector, and a base on which the resistance track and the collector are printed. The lateral terminals are separated from the cover during the step of crimping the cover on the base.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
109 words
A potentiometer device comprising in combination: a conductive cover formed as a single piece molding with a central terminal; a baseplate of insulating material fixed on said cover by means of lips folded and crimped on said plate; a resistance track and collector printed on said baseplate, said collector having an aperture in which is engaged a projection of the central terminal, said resistance track having apertures in which are engaged projections of at least one pair of lateral terminals, at least one rotor of insulating material; at least one slider, said slider being operatively associated with said rotor and in contact with said resistance track and said collector.
Claim 2
Dependent Claim
109 words
A potentiometer device comprising in combination: a conductive cover formed as a single piece molding with a central terminal; a baseplate of insulating material fixed on said cover by means of lips folded and crimped on said plate; a resistance track and collector printed on said baseplate, said collector having an aperture in which is engaged a projection of the central terminal, said resistance track having apertures in which are engaged projections of at least one pair of lateral terminals, at least one rotor of insulating material; at least one slider, said slider being operatively associated with said rotor and in contact with said resistance track and said collector.
Claim 3
Dependent Claim
68 words
A potentiometer according to claim 1, wherein said slider is of annular metallic form, said slider having an aperture and a slot diametrically positioned, the aperture and the slot being engaged by a pair of knobs projecting from the disc of said rotor, the aperture and the slot being positioned at equal distances between the points of contact of said slider with said resistance track and said collector.
Claim 4
Dependent Claim
38 words
A potentiometer according to claim 2 wherein the points of contact of said slider are a pair of feet one of which is in contact with said resistance track and the other being in contact with said collector.
Claim 5
Dependent Claim
29 words
A potentiometer according to claim 3 including extension means extending from each of said terminals, said central terminal extension means being molded with said cover and extending perpendicularly therefrom.
Claim 6
Dependent Claim
28 words
A potentiometer according to claim 3, including extension means operatively connected to said central terminal molded with said cover and extending parallel to the plane of said cover.
Claim 7
Dependent Claim
14 words
A potentiometer according to claim 5, wherein said extension means have circular cross sections.
Claim 8
Dependent Claim
26 words
A potentiometer according to claim 2, including a rod extending from said rotor, said rod having a slot capable of being engaged by an adjustment tool.
Claim 9
Dependent Claim
16 words
A potentiometer according to claim 2 wherein said rotor is provided with a knurled outer edge.
Claim 10
Dependent Claim
15 words
A potentiometer according to claim 2, wherein the disc of said rotor is elastically deformable.
Claim 11
Dependent Claim
17 words
A potentiometer according to claim 4, wherein said central terminal extension means has a circular cross section.
Claim 12
Dependent Claim
43 words
A potentiometer according to claim 1, including a slider having a central member in the form of a truncated cone received in a correspondingly shaped recess in said cover, said central member including a slot in which may be engaged an adjustment tool.
Claim 13
Dependent Claim
34 words
A potentiometer according to claim 11, wherein said central member has a foot and said cover has a boss forming a stop with the foot and thereby limit the radial movement of said slider.
Claim 14
Dependent Claim
29 words
A potentiometer according to claim 11, wherein said cover and said baseplate have openings through which the adjustment tool may pass to engage the slot of said central member.
