  • Publication number: 20140255079
    Abstract: Disclosed is a telescoping writing implement that retracts the writing point when in the collapsed position. Importantly, it is simple in design, uses a minimized number of parts, and, uses no metal coil spring. In its most general form, an external pen body is mechanically connected to a writing cartridge such as ballpoint pen refill or touch screen stylus through at least one aperture in a guide tube. Movement of the external pen body downward draws the writing cartridge down inside the guide tube until the writing end of the writing cartridge is exposed and the connecting means such as a clip, screw or pin contacts the lower edge of the aperture or apertures. When the outer pen body is moved upward, it draws the writing cartridge with it inside the guide tube until the writing end is protected inside the guide tube. The limits of travel are governed by the dimensions of the aperture or apertures when the connecting means contacts the edge of the aperture or apertures.

  • Patent number: 8794857
    Abstract: A non-consumable writing implement, such as a mechanical pencil, with a consumable tip has a body with an outer housing. (See definitions in the “Summary” section). An inner retainer with a gripping mechanism is adapted to grip a consumable product held therein. That is, in one embodiment, a piece of graphite is gripped inside a mechanical pencil. The inner retainer, held within the outer housing, and a ballast attached to the inner retainer, are rotatable with respect to the outer housing. The ballast rotates the gripping mechanism and the consumable product. In this manner, a user desiring to have the tip of the consumable product always in the same orientation as he writes, may use this device to do so. A damper and detent mechanism may be employed to prevent harmonic movement or turning of the consumable product during writing.

    Abstract: In a mechanical pencil, a tubular lead reservoir is connected to the rearward end of a lead chuck. A cylindrical weight is fitted slidably around the lead reservoir and is adapted to strike against the chuck to open the same to allow forward feed of the lead when a forward shake is applied to the pen barrel. In order to prevent forward feed of the lead as a result of unintended forward shake while carrying the pencil, a slider disposed rearwardly of the lead reservoir has a radially outwardly extending engagement projection which is adapted to slidably engage either a longitudinal guide slot in the pen barrel or a lateral slot circumferentially and rearwardly extending in the pen barrel. When the engagement projection is in engagement with the lateral slot, the chuck is caused to take an advanced position in which the chuck is open so that a forward stroke cannot feed the lead forward.

    Abstract: The present invention relates to a swing-type mechanical pencil wherein lead can be extended from a head member connected to an outer sleeve by swinging the outer sleeve to move a knocking hammer. The knocking hammer applies a lead-feeding action to feed the lead. A chuck shutting hammer is mounted between a spring bearing of a chuck ring sleeve retaining a chuck ring which is a component of the lead holder and a second spring connected with the chuck. An upward movement of the chuck shutting hammer forces the chuck into a chuck ring. This provides a positive action to shut the chuck preventing slipping of the lead when writing with the mechanical pencil. Manual advance of lead is provided by a slider in a recession an outer surface of the sleeve that engages the lead holder allowing the chuck to be manually opened to extend lead.

    Abstract: A ball point pen has a cartridge which can be projected by orienting the front end of a ball point pen main body downward and which can be retracted by orienting the front end of the main body upward. A weight with a notch or the like is mounted to the cartridge to shift the overall center of gravity of the cartridge and the weight from the axis of the main body. This allows complete engagement of the distal end portion of the cartridge with an engaging step formed inside the main body, so that accidental retraction of the cartridge back into the main body may be prevented during writing.

  • Patent number: 4352580
    Abstract: A knock-out type mechanical pencil has a supporting rod mounted with an eraser at its rear end and axially slidably engaged within the interior of a cylindrical knock-button. A tubularly cylindrical weight is axially slidably engaged around the supporting rod. A cylindrical magnet is axially magnetized and secured to the inner peripheral surface of the knock-button. An annularly inwardly raised guide portion is formed on the inner peripheral surface of the knock-button for guiding the weight to the axial line of the knock-button when the weight is axially slidably dropped downwardly toward the writing tip of the pencil. To protrude and fix an eraser from the rear end of the tubular cylindrical body, the rear end of the pencil is tilted downward. To automatically contain or retract the eraser in the knock-button, the writing tip of the pencil is directed downwardly in writing state.

  • Patent number: 4315695
    Abstract: This invention relates to inertia pens, or writing or marking devices wherein a sleeve is shifted by axial impulse between a position exposing the writing tip and a position enclosing the writing tip. The kinetic energy of the impulse is transmitted to a calibrated mass slide within the pen which slide transfers its energy to the sleeve. A return spring is utilized and the pen may be simple, compound, binary or multifunctional. By obviating the push button or other manual actuator, writing or marking elements may be provided at both ends.

  • Patent number: 4266881
    Abstract: The pen consists of two pen bodies, preferably identical, which interlock with each other in a plurality of longitudinal positions. Each of the pen bodies is preferably provided with a seat for positioning a ball point cartridge therein. Movement of the pen bodies will cause the cartridges seated therein to be protracted or retracted.

  • Patent number: 4176979
    Abstract: A ball-point pen having simple operating and holding mechanism for ink tube including a ball-point and being capable of retracting and extruding the ball-point with a simple action of turning ball-point tip end of the pen up and down is provided. The ink tube has at its inner end opposite to the ball-point a magnetizable lid and around its body a weight freely slidable between said inner end and a projection provided adjacent the ball-point tip end, while holder tube of the pen has a magnetic member secured adjacent an end facing said lid of the ink tube for magnetically holding said lid and the ink tube when the ball-point is retracted, and a stepped part for locking the lid's end when the ball-point is extruded. When the tip end of the pen is turned down, the weight strikes the projection to separate the lid and hence the ink tube from the magnetic member and, when the tip end is turned up, the weight urges the lid's end to be unlocked from the stepped part.

  • Patent number: 4063829
    Abstract: A liquid container having a captive brush in one end. A cylindrical cap seals the container and brush when not in use. To paint a small object, the cap is removed, the container is inverted, and the brush emerges from the container ready for use. A ball valve in the container adds liquid to the brush by inverting the container.

  • Patent number: 4035091
    Abstract: A training device for assisting a student in his endeavor to develop an optimum writing speed, particularly in the art of stenography. The device includes a writing instrument, e.g., a ball-point pen or the like, for manually scribing the characters prescribed in the art. The device is characterized by a cumbersome weight being attached to the writing instrument for exercising and overdeveloping or strengthening the student's muscles that are normally utilized while making the prescribed characters. The student subsequently substitutes the training device with a conventional light weight writing instrument which he is now capable of using with extraordinary dexterity.
