Abstract: Weather resistant push button operator assemblies usable with a variety of latch and lock systems are disclosed that employ O-ring seals along inner and outer diameters of tubular push button operators that may be provided with key operated lock cylinders. A clamp-on bracket and linkage assembly is disclosed that may be used to enable the push button operator assemblies to pivot pairs of latch connected links in opposite directions to concurrently release pairs of remotely located latches.

Abstract: A latch, lock and hinge system having components that are well suited for use with closures such as tonneau covers that close the upwardly opening rear cargo compartments of pickup trucks and the like, includes rotary latch assemblies that are mounted on hinges for releasably engaging latch strikers to provide cover mounting connections that permit the cover both to pivot between open and closed positions, and to be removed when desired. The hinges have pivotally connected arms that are biased to hold the hinge-carried latches adjacent the cover when the cover is removed. Also included are other rotary latch assemblies that are connected by flexible cables to a latch operator assembly having an elongate housing that defines near its opposite ends a pair of recesses wherein latch operators are nested that can be concurrently moved toward each other by the fingers of one hand to unlatch and pivot open the cover. The latch operator assembly is lockable to prevent the cover from being opened and/or removed.

Abstract: A locking system for toolboxes, industrial cabinets and the like includes a push button operator assembly connected by at least one movable link to at least one latch mechanism configured to latchingly engage an associated striker to releasably retain a first structure (such as a closure) on which the striker is mounted in a closed position relative to a second structure (such as a cabinet) on which the locking system is mounted. The push button operator assembly has a button that, when unlocked, can be depressed to move the associated link to unlatch the latch mechanism from the striker, and that, when locked, is inoperable when depressed to move the link.

Abstract: A nut for use with an elongated rod having one end anchored by a hardened resin grouting mix in a drill hole in a mine roof or other such rock formation. The nut has a body portion with a threaded bore through which the rod is advanced and a dome-shaped wall surrounding one end of the bore in radially outwardly spaced relation and an annular lip defining an opening in coaxial, axially spaced relation to the one end of the bore. A metal disc, either solid or with a central opening of smaller diameter than the bore, is positioned in covering relation to the bore and surrounded by the dome-shaped wall. As the rod is advanced through the nut, the disc is moved into contact about its entire periphery with the inside of the dome-shaped wall and rotation of the nut is transmitted to the rod to mix the resin components within the drill hole.

Abstract: A key-operated ignition lock has a housing configured to protectively shield an electrical switch. An operating knob has a tubular body that extends through a first passage defined by the housing, and is rotable therein between a plurality of angular positions including on “off” position. The tubular body defines a second passage wherein elements including a key-receiving plug of a lock mechanism are journaled for rotation between “locked” and “unlocked” positions. Alignable bores formed 1) in the tubular body, 2) in a locking plate that surrounds the tubular body, 3) in the plug, and 4) in a barrel that surrounds the plug support an end-to-end arrangement of pins that permit a suitably configured key to be inserted into the plug only when the knob is in its “off” position, and to permit the knob to be rotated out of its “off” position only when the key is removed from the plug.

Abstract: The disclosed apparatus is a stand alone integrated smart card circuit chip card vending machine. It accepts bills in $1, $5, $10, $20 and $50 denominations and/or credit cards and issues stored value smart cards for the value requested. It can also telephone a center to validate credit card transactions or send diagnostic and statistical reports. This invention has the capability to read and write to a card while it is in the dispenser stack, therefore the card has no value while in the dispenser and is not released until payment is received, that is, the cards are encoded in real time before they are issued.
