1. A device which is manually powered for dispensing material of indeterminate length, which device comprises:

  • a. a feeder, which is movably supported between an initial position and a cutting position, the feeder comprising a means of yieldably retaining from which an extended material end may be disposed in a cantilever manner, wherein if a first pulling force which is less than a drag force were to be exerted upon the extended material end, then the material would not move relative to the feeder, and wherein if a second pulling force which is equal to or greater than the drag force were to be exerted upon the extended material end, then the material would move relative to the feeder;

    b. a stop for preventing movement of the feeder beyond the cutting position in a direction away from the initial position;

    c. a stored energy means, wherein energy of the stored energy means increases when the feeder is moved away from the initial position, the stored energy means providing a bias force urging the feeder to move toward the initial position, wherein the bias force is less than the drag force at every feeder position;

    d. a cutter, having a sharp edge;

    whereby it necessarily follows, if the first pulling force were to be exerted upon the extended material end, then the feeder would move away from the initial position; and

    whereby thereafter if the feeder is stopped at the cutting position and the second pulling force where to be exerted on the extended material end, then the feeder would yield an additional length of material; and

    whereby thereafter if the additional length of material were to be manually forced against the sharp edge, then it would sever; and

    whereby thereafter if the additional length of material were to be severed, then the stored energy means would cause the feeder to return to the initial position;

    wherein thereafter, a distance between a cut edge of a new extended material end and the sharp edge would increase.
