Abstract
Abstract Removable device for tapping power from a continuous outlet duct having a stylized extruded housing is constructed with gear elements interconnecting the contact carrier and two mechanical retaining elements. A single manually operated lever is provided to operate the gear elements to simultaneously make electrical and mechanical holding connections between the power tap and the duct. Appropriately located spring fingers mounted to the power tap contact the duct housing to provide a positive ground connection, and cooperating polarizing formations of the power tap and duct protect against the making of improper electrical connections.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
139 words
A device for tapping power from a continuous outlet duct having a housing with a longitudinal access slot and enclosing a plurality of longitudinally extending bus bars; said device including a plurality of contacts engageable with duct bus bars, carrier means having a nose portion to which said contacts are mounted, with said nose portion being insertable into a duct housing through its access slot, support means to which said carrier means is pivotally mounted, mechanical securing means mounted to said support means remote from said carrier means and engageable with securing formations of a duct housing located adjacent its access slot, and first means interconnecting said carrier means and said securing means whereby pivoting of said carrier means from an inserting position to an operating position operates said securing means from a mounting position to a holding position.
Claim 2
Independent Claim
139 words
A device for tapping power from a continuous outlet duct having a housing with a longitudinal access slot and enclosing a plurality of longitudinally extending bus bars; said device including a plurality of contacts engageable with duct bus bars, carrier means having a nose portion to which said contacts are mounted, with said nose portion being insertable into a duct housing through its access slot, support means to which said carrier means is pivotally mounted, mechanical securing means mounted to said support means remote from said carrier means and engageable with securing formations of a duct housing located adjacent its access slot, and first means interconnecting said carrier means and said securing means whereby pivoting of said carrier means from an inserting position to an operating position operates said securing means from a mounting position to a holding position.
Claim 3
Dependent Claim
33 words
A device as set forth in claim 1 also including deflectable grounding contact means mounted to said support means and engageable with a duct housing in the vicinity of its longitudinal access slot.
Claim 4
Independent Claim
141 words
A device for tapping power from a continuous outlet duct having a housing with a longitudinal access slot and enclosing a plurality of longitudinally extending bus bars; said device including a plurality of contacts engageable with duct bus bars, carrier means having a nose portion to which said contacts are mouNted, with said nose portion being insertable into a duct housing through its access slot, support means to which said carrier means is pivotally mounted, mechanical securing means mounted to said support means and engageable with securing formations of a duct housing located adjacent its access slot, and first means interconnecting said carrier means and said securing means whereby pivoting of said carrier means from an inserting position to an operating position operates said securing means from a mounting position to a holding position, said first means including interengaged gear elements.
Claim 5
Independent Claim
141 words
A device for tapping power from a continuous outlet duct having a housing with a longitudinal access slot and enclosing a plurality of longitudinally extending bus bars; said device including a plurality of contacts engageable with duct bus bars, carrier means having a nose portion to which said contacts are mouNted, with said nose portion being insertable into a duct housing through its access slot, support means to which said carrier means is pivotally mounted, mechanical securing means mounted to said support means and engageable with securing formations of a duct housing located adjacent its access slot, and first means interconnecting said carrier means and said securing means whereby pivoting of said carrier means from an inserting position to an operating position operates said securing means from a mounting position to a holding position, said first means including interengaged gear elements.
Claim 6
Dependent Claim
30 words
A device as set forth in claim 3 in which the mechanical securing means includes spaced first and second sections, said carrier means having a portion extending between said sections.
Claim 7
Dependent Claim
52 words
A device as set forth in claim 4 in which a first and a second of said gear elements are keyed to the respective first and second sections, a third of said gear elements being keyed to said carrier means and being in driving engagement with the first and second gear elements.
Claim 8
Dependent Claim
29 words
A device as set forth in claim 5 in which there is a radial extension projecting from said carrier means for manually supplying power to operate said gear elements.
Claim 9
Dependent Claim
26 words
A device as set forth in claim 6 in which there is an individual deflectable grounding element adjacent to each of said first and second sections.
Claim 10
Dependent Claim
33 words
A device as set forth in claim 7 in which said gear elements are mounted on parallel axes and free portions of said grounding elements extend generally in the direction of said axes.
Claim 11
Dependent Claim
61 words
A device as set forth in claim 5 in which the support means includes first and second spaced parallel plates, said gear elements positioned between said plates and to the rear of said first plate; said nose portion, said sections and a grounding means extend forward of said first plate; said gear elements being mounted to axes perpendicular to said plates.
Claim 12
Dependent Claim
57 words
A device as set forth in claim 5 in which the gear elements are mounted to parallel axes; said first and second sections including respective first and second holding portions that are elongated and relatively thin; said axes for said first and second gear elements being at right angles to the respective first and second holding portions.
Claim 13
Dependent Claim
51 words
A device as set forth in claim 3 in which there is a housing wherein said gear elements are disposed, said housing including polarizing formations on opposite sides of the nose portion; with said carrier means in said inserting positions said nose portion being non-symmetrical with respect to said polarizing formations.
