  • Patent number: 5074041
    Abstract: A nail clipping retainer which prevents the scattering of fingernail and toenails from the cutting area of conventional nail clippers. The device retains nail fragments only as each fragment is being cut. The device mounts on the post between the upper and lower cutting members and fills the void between the cutting members when the members are fully depressed during a cutting process. Alternate methods of attachment and simplicity of manufacture allow for easy installation in new and previously produced nail clippers of various shapes and sizes. An optional clipping container may be used to store clipping after being retained by the retaining member described above. The clipping container detachably fastens to the post at the exterior side of the lower cutting member with a thin linear member equal in shape to the lower cutting member.

  • Patent number: 5042154
    Abstract: A utility knife comprises a lower elongate part shell 1 and an upper such part shell 3 forwardly fitted with interengaging wedging surfaces whereby they clamp together on relative longitudinal movement. This movement is achieved by turning nut 2 on shank 8 to bear on wall 30. The loosening of the nut 2 to unclamp the part shells and thus permit blade 43 to be pushed forward with slider 42 by pushbutton 41 does not separate the part shells 1 and 3 since the end spur 9 of the shank 8 still rides on arresting web 37. Maximum unscrewing of the nut, however, permits separation e.g. for access to stack of spare blades 60 resiliently held at 59 in the rearward part of shell 1 (now unencumbered by the conventional screw-shank), but does not lead to loss of nut 2 because of a complementary detent configuration 25 at the end of the shank and in the end wall 2a of the nut prevents complete nut/shank separation.

    Abstract: A utility knife employs a slide having a cantilevered lever for capturing a blade therein. A leading blade in a reservoir is capturable by the slide using a tooth resiliently affixed to the slide which is positioned to enter a locking hole in the blade. The tooth may be withdrawn from the hole in the blade whereby the blade may be removed for reversal and reinsertion or for discard. When the captured blade is removed, the slide may be returned to the loading position for capturing the next blade from the reservoir. As long as a captured blade is engaged by the tooth, the slide is prevented from returning to the loading position, and the loading blade in the reservoir is prevented from advancing.

    Abstract: A method of making knives in which a separate blade and handle are bonded together by electron-beam welding which reduces the susceptibility to corrosion at the weld area and thereby increases the knife life. In addition, the blade can be unhardened when welded, and hardened after welding to reverse any structural changes occurring in the metal adjacent the weld and thereby more reliably reduce the susceptibility to corrosion at the weld area. The step of hardening the blade after welding can be used to provide satisfactory corrosion resistance in knives where separate blades and handles are joined by other welding techniques such as electrical seam and oxyacetylene welding.

    Abstract: A retractable blade utility knife is formed of a pair of elongated mating handle halves separable along a plane extending longitudinally of the knife and terminating at one end in a blade receiving opening. A blade carrier is mounted between the handle halves for supporting a blade for reciprocation between an exposed and sheathed position. Each of the handle halves is provided with a longitudinal extending slot and the blade carrier is provided with a finger piece extending through one of the slots and a carrier base with an offset extension connected thereto by a necked portion extending through the other of said slots with the necked portion disposed in said slot. The finger piece is threadably received in a threaded dimple on the extension and is rotatable relative thereto to serve the dual function of securing the handle halves together and securing the blade carrier in adjusted position.

  • Patent number: 4005525
    Abstract: A retractable cutting implement, such as a utility knife, comprises a sleeve-like handle member having a cavity portion with the handle member being open at the base and at one end through a first longitudinal slot. A carrier member is pivotally mounted to the handle for pivotal movement into and out of the cavity with the carrier member being resiliently held within the cavity when it is pivotally moved into the cavity for substantially closing the cavity. The carrier member comprises a substantially enclosed longitudinally extending chamber with a passage therein in communication with the one end of the first slot in the handle member and a blade carriage member is slidably mountable in this chamber for slidable movement toward and away from the passage.

  • Patent number: 3964162
    Abstract: A blade scraper has a hand grip casing with a blade storage compartment and a slide mounted in a chamber of the casing for holding a razor blade and permitting retraction of the razor blade into an inoperative position and sliding movement to an operative position with the blade in a scraping position exposed outside of the chamber. A pressure sensitive locking button acts to lock the blade in the inoperative position or the exposed position. A safety button is interconnected with the slide so that pressure must be applied to two actuating buttons in order to expose the blade thus making it difficult for small children to accidentally place the scraper in a mode of operation dangerous for handling. The slide carries a safety dowel for locking the blade compartment when the blade is locked in its inoperative position.
