Abstract: A writing instrument that includes a barrel extending along a longitudinal axis (A) and a tip mounted at the front of the barrel, further including a protective sleeve for the tip, the sleeve being mounted coaxially on the barrel and movable relative to the barrel between a protective position where it covers the tip and a retracted position where it exposes the tip to allow writing. The sleeve includes an inner wall which includes a helical cam engaging with a guide element formed on the barrel so that the sleeve is movable in translation combined with rotation.

Abstract: An apparatus comprises a body that extends longitudinally between a top end and a bottom end, an elongate slot disposed in an outer surface of the body and having first and second spaced-apart detents, and a cap disposed coaxially around the body and having a cut therein that defines an elongate arm. The elongate arm has an inwardly-oriented protrusion configured to engage the detents of the slot. The cap is slidable along the body such that the inwardly-oriented protrusion slides along the slot until it detachably engages a detent, thereby retaining the cap in either a closed position that covers the bottom end or an open position in which the bottom end is exposed.

Abstract: A writing instrument comprises a substantially tubular body extending between a top and a writing end, and an elongate slot disposed in an outer surface of the body and having a detents defined at each end of the slot, and a tubular open-ended cap disposed coaxially around the body and having a cut defining an elongate arm connected to the cap at one end and having an inwardly-oriented protrusion at another end and sized to engage the detents of the slot. The cap is slidable along the body such that the inwardly-oriented protrusion slides along the slot until it engages a detent at an end of the slot thereby arresting the cap either in a closed position, in which the cap covers the writing end, or in an open position in which the writing end is exposed.

Abstract: A portable rock crusher and scarifier for in-situ and on-site crushing, milling, grinding and preparation of road beds having a crusher frame defining a crusher channel journaling a reversibly rotatable arbor carrying plural automatically centering tooling implements in symmetrically spaced V-shaped axial keyways and a power pack releasably attachable to a road maintenance vehicle. An anvil weldment channel defined by spaced apart strongbacks communicates with the crusher channel and carries an adjustably positionable anvil weldment carrying two vertically spaced adjacent anvils proximate the arbor. A canting mounting structure provides attachment to a variety of road maintenance vehicles to provide carriage, support and movement. Milling implements may be installed on the arbor for grinding surfaces at depths below the crusher frame, and the crusher frame and power pack may be attached to a base for stationary operation.

Abstract: An eraser device has an elongated cylindrical finger grip section with an internal bore defined therethrough. An internal conical bore section is aligned with the internal bore so that the device can be slid or fitted onto the writing end of a writing instrument. At least one eraser arm extends radially outward from the finger grip section and angled forward towards the front end of the device. An eraser is configured at the end of the eraser arm so that an operator can use the eraser by merely tilting and rotating the finger grip section to bring the eraser arm and eraser into contact with a writing surface.

Abstract: A writing instrument hand grip to facilitate gripping ease and comfort and to improve handwriting for people with a hand and finger dexterity disability. A pyramidal tetrahedron has a writing material detachably mounted to one or more of its apexes. Its faces may be concavely contoured and provided with friction enhancing surfaces.

Abstract: A grip for a writing instrument is disclosed which has a resilient plastic hollow tube with a plurality of flexible interior ribs extending radially inwardly from the tube and extending axially the length of the tube. A plurality of flexible exterior ribs extend radially outwardly from the tube and extend axially the length of the tube. The interior ribs are adapted to resiliently engage the shank of a writing instrument and the exterior ribs are preferably tapered and provide a resilient, cushioning grip to a writer. The radial thickness of the tube of the grip is small in comparision to the diameter of the tube so that the tube may be inverted or reversed so that the interior ribs extend radially outwardly and the exterior ribs extend radially inwardly. By reversing the grip, the resilient feel of the grip may be modified and the grip may be adapted to writing instruments of lesser diameter.

Abstract: A writing instrument with a slide cap is provided in which the slide cap with a moveable cover is slideable along casing of the instrument from a position wherein it protects the writing tip of the instrument, to a position wherein the writing tip is exposed.

Abstract: A cap for the point of a pen or pencil includes a cap element that is affixed to the writing end of, and captive on, the pen or pencil. The cap is rotatably and slideably moveable between a first extended position for covering and protecting the point, and alternately, a second, retracted position in which the cap element moves further onto the pen or pencil to expose the point for writing.

Abstract: A ball-point pen has an elongate telescopic body which includes a front holder portion and a rear holder portion fitted on the front holder portion to be movable between a compressed position and a stretched position. A ball-point pen refill is disposed in the front holder portion and has a refill tip protruding from one end of the front holder portion. A concealing sleeve is disposed in one end of the front holder portion to be slidable along the ball-point pen refill. When the rear holder portion is moved to the compressed position, the sleeve is moved to conceal the refill tip, and when the rear holder portion is moved to the stretched position, the sleeve is moved to expose the refill tip. When the rear holder portion is moved to the compressed position, the rear holder portion is held in the position by a holding mechanism.

Abstract: A finger gripping device used as a removable attachment to a writing implement is formed as a one piece cylindrical body member made of flexible material. The body has an internal bore of uniform diameter so that it may be slid onto a writing implement. A plurality of circumferential ribs are axially spaced along the outside surface of the cylindrical body. The ribs are formed by closely spaced peaks and valleys.

Abstract: A protective closure for an implement such as a pencil or pen. The closure comprises a retractable sheath intended for an attached relation to the implement body portion. The sheath having fold means is shortened or contracted longitudinally to achieve an exposing position when opposing sections of the sheath are urged together, achieving an intermediate, cross-sectionally continuous fold thereby. The fold means is further adapted to self-retain.

Abstract: A two-part barrel sleeve includes an internal spring finger which rides in a spiral groove in the combined ink reservoir and barrel of a ball pen, the spiral groove having a detent at its rear end to provide a snap-action as the barrel sleeve is retracted to its rearmost position exposing the writing tip for normal use.

Abstract: A cap device for securing an instrument, such as a ballpoint pen, to a web of flexible material. The device comprises a stem portion and a body portion which collectively define a first, second and third surface, with the first surface being disposed between the second and third surfaces. The surfaces are disposed in a spaced array to form a longitudinally extending gap which is serpentine in cross section and arranged for receipt of the web of material to bend the web about the surfaces to accomplish a substantially non-traumatic gathering of the web by the device. The device is slidable from a first position wherein it covers the tip of the writing instrument to a second position wherein the tip is exposed. Means are provided to ensure that the device does not slide off the instrument.

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.
