Abstract
The invention is a ball point pen or the like having an internal mechanism to dispense writing paper from a small roll of same confined within a cylindrical cartridge contained within the pen housing or sheath. The cartridge has a knurled collar which is thumb-operated through an opening in the exterior sheath of the pen to rotate the cartridge approximately one-quarter turn against a spring bias to project the leading edge of the paper roll through a slot in the pen sheath, where it may be gripped and pulled by the user to unroll a desired length and then torn off. Prior to tearing the paper from the remaining roll, the knurled collar is released to withdraw the paper a quarter turn into the sheath so that a sufficient length of leading edge remains for the next dispense.
Claims12
A paper dispensing assembly comprising:
- a. generally cylindrical sheath substantially defining an enclosure and having a longitudinal slot therein;
- b. a generally cylindrical hollow cartridge longitudinally extended within said sheath, said cartridge being self-contained and removable from said sheath and having a longitudinal slot therein to permit the passageway therethrough of paper from a roll contained with the cartridge;
- c. said cartridge being spaced from at least a portion of said sheath adjacent to slot therein to define a space for a projecting end of paper extending through the slot in said cartridge;
- d. means permitting the limited rotation of said cartridge relative to said sheath;
- e. control means operatively connected to said cartridge and accessible from externally of said sheath for rotating said cartridge, whereby the free end of a roll of paper contained within the cartridge and threaded through the slot therein can be positively driven through or retracted from the slot in said sheath by operating said control means to rotate said cartridge.
In a ball point pen having an outer sheath and an ink cartridge extending from the head end of the sheath to the tip end thereof, a paper dispensing assembly comprising:
- a. a substantially hollow cylindrical cartridge disposed within said sheath and having a longitudinal slot therein and having a central axial bore receiving said ink cartridge, said cartridge being spaced from at least a portion of said sheath adjacent said slot;
- b. a roll of paper disposed within said hollow cartridge, said roll being resilient to expand into frictional contact with the surface of said cartridge, and having the leading edge thereof extending through said slot between said cartridge and said sheath;
- c. said sheath also having a longitudinal slot therein of length and axial position substantially equal to the slot in said cartridge;
- d. means accessible externally of said sheath to directly rotate said cartridge relative to said sheath such that said roll of paper can be positively rotationally driven by said cartridge so that the leading edge of said paper roll can be extended through the slot in said sheath or retracted therefrom.
