Dispenser feeder providing extended material end
First Claim
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.

Abstract
A manual dispenser of material of indeterminate length, which is yieldably retained on a movable feeder, such that when the end of the material is pulled, the feeder moves until it reaches a stop, whereupon additional material is yielded from the feeder to a length suitable to the user. The material is then forced to sever against a cutter, creating a useful material segment, and also releasing the feeder to return to its initial position, powered by a biasing spring. Upon return, the feeder holds the remnant end of the material extended, readily accessible for grasping. An alternate embodiment comprises a movable cutter.

15. A manually powered tape dispenser for dispensing segments of tape of the type which has adhesive on at least one side, which dispenser 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 tape 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 tape end, then the tape 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 tape end, then the tape 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 tape 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 tape end, then the feeder would yield an additional length of tape; and
whereby thereafter if the additional length of tape were to be manually forced against the sharp edge, then it would sever; and
whereby thereafter if the additional length of tape 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 tape end and the sharp edge would increase. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30)
