  • Patent number: 9004014
    Abstract: Tethering stakes of the nature intended to be pounded flush with or below ground level. Certain of the tethering stakes include a cap on the pounding end which is adapted for ease of placement and release of a tethering line. Accordingly, the tethering line can be removed from the stake when it is to be pounded into the ground and then engaged with the stake only when tethering is desired. Certain of the embodiments include caps having uniquely shaped apertures for securing the tethering line. Another includes an aperture in communication with an aperture in the stake such that a lead cable or the like may be moved out of the way when the stake is pounded into the ground and may be fully received within the stake when tethering is not desired. Another embodiment employs a coupler passing through an aperture directly beneath the pounding surface to facilitate ease of attachment and removal of the tethering line.

  • Patent number: 9004015
    Abstract: A tethering stake includes a rod having a point at one end thereof and a driving cap at an opposite end. A collar is fixed to the rod adjacent to and spaced from the driving cap, thus providing a neck to receive a tether line or chain. A cap cover is slidingly received upon the rod and is adapted to be selectively engaged with the collar. The cap cover includes a central circular aperture with a radial slot extending therefrom. The centrally positioned aperture and slot allow the cover to assume a position substantially parallel to the rod during shipment and storage, while allowing it to take a position substantially orthogonal to the rod when the rod is driven into the ground.

  • Patent number: 7758202
    Abstract: A step stool with positionable lights and a rechargeable battery is carried upon retractable casters for suitable positioning and utility. A motion and timer switch is interposed between the battery and the positionable lights to allow the positionable lights to be illuminated only for a fixed period of time following movement of the step stool. The lights may be positionable as by adjustable brackets or by a cord reel assembly. The step stool has contact bands thereabout that are adapted for engagement with contacts in a charging station that is specifically configured to receive the step stool. Receipt of the step stool by the charging station activates a battery charger that serves to charge the battery of the step stool thereafter. A solenoid switch disconnects the lights of the step stool upon commencement of the charging operation.

  • Patent number: 5501134
    Abstract: A multi-stage trigger assembly for use by a shooter of a firearm. Specifically an AR-15 or M-16 although other types of firearms could be used. The invention comprises a trigger, a disconnector, disconnector spring, and a hammer. The trigger and the hammer each include a respective engagement means for engaging each other so that the hammer is held in a cocked position by the trigger before the trigger is pulled. The hammer further includes a contact means for contacting the disconnector so that when the trigger is first pulled (the first stage) the contact means contacts the disconnector at a predetermined time and increases the pressure required to pull the trigger completely and disengage the engagement means of the hammer and the trigger (the second stage). Additionally, the disconnector is spring loaded by the disconnector spring and pivotally connected to the trigger.

  • Patent number: 5463834
    Abstract: A ground attaching assembly for confining an attached object to a limited distance from a predetermined ground position includes an elongated stake member having a ground penetrating end and a driven impact end spaced from the penetrating end. The driven impact end is capable of receiving blows from an associated pounding member such as a hammer. An object securing line is connected to the stake member at an attachment position between the penetrating end and the driven impact end, providing space between the attachment position and the impact end whereby the securing line may be spaced from the impact end and thereby be protected from blows from the associated pounding member.

  • Patent number: 5412895
    Abstract: A floating gun barrel mount having the barrel free to remain straight and free of deflection by the sling because it is not attached to the forearm, and a two piece barrel nut to allow universal alignment of gas tube openings. The two piece barrel nut allows for mass production of the barrel nut, allows alignment for any rotational position of the threads on the barrel receiver, and still provides the high amount of pressure required to secure the barrel firmly to the receiver.
