Abstract
Abstract A punchcard read-feed mechanism having a plurality of opposing pairs of card feed rollers wherein only one roller of each pair is directly associated with a main power source through appropriate gearing while the other rollers of each pair are not associated with any gearing and are driven by the first-mentioned rollers of each pair, making it possible where desirable to mount all of the nongear driven rollers on a separate carrier which is separable from the structure supporting the gear-driven rollers whereby cleaning and clearing the mechanism is greatly facilitated. A card switch mechanism as part of the punchcard read-feed mechanism having an actuator arm disposed at the center of the card read mechanism whereby the card read switch is operated by any card passing through the read-feed mechanism regardless of its column width.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
135 words
In a punchcard read-feed mechanism the combination comprising: a main support frame; a roller carrier pivotally connected to said main support frame and having a closed position in which said carrier is at its closest position relative to said main frame and an open position in which said carrier is pivotally positioned at a spaced apart location from said main support frame; a plurality of gear-driven feed rollers mounted on said support frame at spaced apart locations; and a plurality of resilient, nongear-driven rollers mounted on said roller carrier, wherein each of said resilient rollers is mounted to be disposed in juxtaposition to one of said geardriven rollers and in driving engagement therewith when said carrier is pivoted to its closed position whereby rotation of said gear driven rollers causes rotation of said nongear-driven rollers.
Claim 2
Dependent Claim
135 words
In a punchcard read-feed mechanism the combination comprising: a main support frame; a roller carrier pivotally connected to said main support frame and having a closed position in which said carrier is at its closest position relative to said main frame and an open position in which said carrier is pivotally positioned at a spaced apart location from said main support frame; a plurality of gear-driven feed rollers mounted on said support frame at spaced apart locations; and a plurality of resilient, nongear-driven rollers mounted on said roller carrier, wherein each of said resilient rollers is mounted to be disposed in juxtaposition to one of said geardriven rollers and in driving engagement therewith when said carrier is pivoted to its closed position whereby rotation of said gear driven rollers causes rotation of said nongear-driven rollers.
Claim 3
Dependent Claim
43 words
The read-feed mechanism of claim 1 further comprising: mechanical spacing means disposed between said main support frame and said carrier to accurately determine the positions of said nongear-driven rollers relative to said gear-driven rollers when said carrier is pivoted to its closed position.
Claim 4
Dependent Claim
38 words
The read-feed mechanism of claim 2 wherein said spacing means is dimensioned to produce at least a 0.005 inch interference clearance between said gear-driven rollers and said nongear-driven rollers when said carrier is pivoted to its closed position.
Claim 5
Dependent Claim
26 words
The read-feed mechanism of claim 2 further comprising; latching means disposed on said support frame structure and operative to secure said carrier in its closed position.
Claim 6
Dependent Claim
149 words
In a punchcard read means characterized by a cylindrical read roller, a plurality of brushes disposed longitudinally along the roller, a slotted comb between the roller and brushes through which the brushes extend, and a bracket for holding the roller, comb and brushes in their relative positions, the combination comprising; a card switch for directing electric potential to the roller, having an actuator, disposed on the bracket on the brush side of the comb; a card switch actuator lever disposed on the bracket at a location approximately midway between the ends of the roller and including a portion which extends through a slot in the comb to a position adjacent and beyond the roller portion closest to the comb whereby a card passing between the roller and comb will engage said lever, said lever operatively associated with said switch actuator to operate said switch when engaged by a card.
Claim 7
Dependent Claim

Claim 8
Dependent Claim
35 words
The read means of claim 5 further comprising; a pivot means for supporting said lever on the bracket whereby said lever is pivoted into operative engagement with said switch actuator when engaged by a card.
Claim 9
Dependent Claim
15 words
The read means of claim 6 wherein said actuator is formed of an insulator material.
