Abstract
Abstract There is herein disclosed a printed wiring card file including a front support formed of a rectangular tubular member having a slotted steel card guide on its top and bottom surfaces and a rear support formed of a circular tubular member having a slotted card guide at the top and bottom. The front card guide slots are so shaped as to align a wiring card horizontally with the rear card guide slots while the rear support member serves to vertically align the wiring card during insertion.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
170 words
A printed wiring card file including a plurality of vertically adjacent card file shelves, adapted for mounting to a wiring backplane, each said shelf comprising a forward supporting member of substantially rectangular crosssection, and a first wiring card guide member including a plurality of parallel card guide slots affixed to the upper and lower surfaces of said forward supporting member, a rearward supporting member of substantially circular crosssection, and a second wiring card guide member including a plurality of parallel card guide slots affixed to said rearward supporting member, means for suspending said forward and rearward supporting members in a substantially parallel spaced apart relationship with the card guide slots of said first and second wiring card guide members in substantial alignment, and said card guide slots in said first wiring card guide member having dimensions such that the maximum horizontal misalignment of a printed wiring card inserted therein is less than one half the spacing between two adjacent parallel and guide slots in said second wiring card guide member.
Claim 2
Dependent Claim
170 words
A printed wiring card file including a plurality of vertically adjacent card file shelves, adapted for mounting to a wiring backplane, each said shelf comprising a forward supporting member of substantially rectangular crosssection, and a first wiring card guide member including a plurality of parallel card guide slots affixed to the upper and lower surfaces of said forward supporting member, a rearward supporting member of substantially circular crosssection, and a second wiring card guide member including a plurality of parallel card guide slots affixed to said rearward supporting member, means for suspending said forward and rearward supporting members in a substantially parallel spaced apart relationship with the card guide slots of said first and second wiring card guide members in substantial alignment, and said card guide slots in said first wiring card guide member having dimensions such that the maximum horizontal misalignment of a printed wiring card inserted therein is less than one half the spacing between two adjacent parallel and guide slots in said second wiring card guide member.
Claim 3
Dependent Claim
170 words
A printed wiring card file including a plurality of vertically adjacent card file shelves, adapted for mounting to a wiring backplane, each said shelf comprising a forward supporting member of substantially rectangular cross-section, and a first wiring card guide member including a plurality of parallel card guide slots affixed to the upper and lower surfaces of said forward supporting member, a rearward supporting member of substantially circular cross-section, and a second wiring card guide member including a plurality of parallel card guide slots affixed to said rearward supporting member, means for suspending said forward and rearward supporting members in a substantially parallel spaced apart relationship with the card guide slots of said first and second wiring card guide members in substantial alignment, and said card guide slots in said first wiring card guide member having dimensions such that the maximum horizontal misalignment of a printed wiring card inserted therein is less than one half the spacing between two adjacent parallel and guide slots in said second wiring card guide member.
Claim 4
Dependent Claim
170 words
A printed wiring card file including a plurality of vertically adjacent card file shelves, adapted for mounting to a wiring backplane, each said shelf comprising a forward supporting member of substantially rectangular cross-section, and a first wiring card guide member including a plurality of parallel card guide slots affixed to the upper and lower surfaces of said forward supporting member, a rearward supporting member of substantially circular cross-section, and a second wiring card guide member including a plurality of parallel card guide slots affixed to said rearward supporting member, means for suspending said forward and rearward supporting members in a substantially parallel spaced apart relationship with the card guide slots of said first and second wiring card guide members in substantial alignment, and said card guide slots in said first wiring card guide member having dimensions such that the maximum horizontal misalignment of a printed wiring card inserted therein is less than one half the spacing between two adjacent parallel and guide slots in said second wiring card guide member.
Claim 5
Dependent Claim
17 words
Apparatus as recited in claim 1 wherein said forward and rearward supporting members are hollow tubular members.
Claim 6
Dependent Claim
43 words
Apparatus as recited in claim 2 wherein the walls of said hollow tubular members are perforated, and further including means for forcing air into the ends of said tubular members such that air is forced through said perforations into said wiring card file.
Claim 7
Dependent Claim
55 words
Apparatus as recited in claim 1 wherein each of said first and second wiring card guide members comprise an elongate sheet metal member having a plurality of opposed parallel transverse slots disposed in the longitudinal edges thereof and formed about said forward and rearward supporting members to provide said upper and lower card guide slots.
Claim 8
Dependent Claim
33 words
Apparatus as recited in claim 1 wherein the forward ends of each of said card guide slots include An entry portion which curves horizontally outwardly to define a preselected wiring card acceptance dimension.
Claim 9
Dependent Claim
39 words
Apparatus as recited in claim 5 wherein said maximum horizontal misalignment of said printed wiring card is no greater than one half said wiring card acceptance dimension of said card guide slots in said second wiring card guide member.
