Abstract
Abstract Tape cutting means comprising a stationary cutting edge and a movable anvil, particularly useful in severing sound recording and sound playback tape of the type commonly used in cassettes and cartridges, characterized by the fact that the cutting edge is one of 12 edges of a cube which may be mounted in one of several positions to present any one of its 12 edges to the anvil for tape severance.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
149 words
Tape cutting means comprising a vertically mounted stationary cutting edge means, and a vertically mounted horizontally movable anvil bar; the anvil bar comprising a vertically positioned bar pivotally mounted on a horizontal axis at its lower end; and having an anvil insert at its upper end for cooperation with the cutting edge means; means for passing a tape edgewise and horizontally across the cutting edge means between it and the anvil insert; a strong spring for biasing the anvil bar upper end away from the cutting edge means; a solenoid plunger spring actuating means for biasing the anvil bar upper end towards the cutting edge means in opposition to the strong spring; a support for mounting the cutting edge means, the anvil bar, the strong spring, and the actuating means; and a table above and mounting the support and having a slot for the anvil bar in its movement.
Claim 2
Dependent Claim
149 words
Tape cutting means comprising a vertically mounted stationary cutting edge means, and a vertically mounted horizontally movable anvil bar; the anvil bar comprising a vertically positioned bar pivotally mounted on a horizontal axis at its lower end; and having an anvil insert at its upper end for cooperation with the cutting edge means; means for passing a tape edgewise and horizontally across the cutting edge means between it and the anvil insert; a strong spring for biasing the anvil bar upper end away from the cutting edge means; a solenoid plunger spring actuating means for biasing the anvil bar upper end towards the cutting edge means in opposition to the strong spring; a support for mounting the cutting edge means, the anvil bar, the strong spring, and the actuating means; and a table above and mounting the support and having a slot for the anvil bar in its movement.
Claim 3
Dependent Claim
56 words
Tape cutting means according to claim 1 wherein the cutting edge means is a cube having 12 edges; and having vertical and horizontal holes through it, enabling a bolt passed through either hole to mount the cube in a manner to present any one of its 12 edges to a cooperating anvil insert alternatively as desired.
Claim 4
Dependent Claim
173 words
A tape cutting means comprising a normally spaced apart anvil and cutting edge means; means for passing a tape edgewise across the cutting edge means and spaced between said anvil and cutting edge means; a solenoid actuated plunger; means interconnecting the free end of said plunger with one of said anvil and cutting edge means for effecting a forceful relative operative engagement of one with respect to the other thereof, to sever the tape therebetween; and a support for mounting said anvil and cutting edge means, said cutting edge means being stationary; said anvil including an anvil bar at one end pivoted upon said support and adjacent its other end mounting an anvil insert, a compression spring interposed between said suPport and anvil bar; said cutting edge means including a cube having 12 edges; having vertical and horizontal holes through it, enabling a bolt to pass through either hole to mount the cube upon said support in a manner to present any one of its 12 edges to the cooperating anvil insert alternately.
Claim 5
