Abstract
Abstract Mechanical storage apparatus for a repertory dialer including a pair of conductor bearing boards with contacts selectively interconnecting the conductors on one board with the conductors on the other providing a preestablished set of paths for routing successive pulses representing the digits and digital values of a stored directory number to succeeding circuitry which generates corresponding digital signals for use in setting up a communication path.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
206 words
In a telephone repertory dialing system, program means comprising a stack of sheets of insulating material including a first sheet having a first group of conductors disposed on a surface thereof, a second sheet of insulating material stacked over said first sheet and having a second group of conductors disposed on a surface thereof opposite to the conductor bearing surface of said first sheet, a third sheet of insulating material interposed between said first and second sheets, spacing said first sheet from said second sheet and insulating the conductors on said first sheet from the conductors on said second sheet, and connecting means disposed on said third sheet for selectively interconnecting the conductors of said first and second groups to establish predetermined paths over said program means, said connecting means including an S-shaped contact spring for establishing one of said paths, said contact spring having first and second contact portions, said first contact portion extending from said third sheet adjacent said first sheet and contacting a first conductor on said first sheet, said second contact portion extending from said third sheet adjacent said second sheet and contacting a second conductor on said second sheet whereby said first and second conductors are interconnected by said contact spring.
Claim 2
Dependent Claim

In a telephone repertory dialing system, program means comprising a stack of sheets of insulating material including a first sheet having a first group of conductors disposed on a surface thereof, a second sheet of insulating material stacked over said first sheet and having a second group of conductors disposed on a surface thereof opposite to the conductor bearing surface of said first sheet, a third sheet of insulating material interposed between said first and second sheets, spacing said first sheet from said second sheet and insulating the conductors on said first sheet from the conductors on said second sheet, and connecting means disposed on said third sheet for selectively interconnecting the conductors of said first and second groups to establish predetermined paths over said program means, said connecting means including an S-shaped contact spring for establishing one of said paths, said contact spring having first and second contact portions, said first contact portion extending from said third sheet adjacent said first sheet and contacting a first conductor on said first sheet, said second contact portion extending from said third sheet adjacent said second sheet and contacting a second conductor on said second sheet whereby said first and second conductors are interconnected by said contact spring.
Claim 3
Dependent Claim
45 words
Apparatus as set forth in claim 1 in which said third sheet has a plurality of apertures located adjacent said first and second conductors on said first and second sheets, said contact spring threading said apertures to be positioned adjacent said first and second conductors.
Claim 4
Dependent Claim
40 words
Apparatus as set forth in claim 2 in which said contact spring includes means integrally formed at one end thereof engaging the surfaces of said third sheet adjacent one of said apertures to maintain said contact spring in said apertures.
