  • Patent number: 5735147
    Abstract: An apparatus is adapted to prevent the theft of a wheeled vehicle having air brakes (e.g., large trucks and buses). A brake valve is selectively actuated by linear movement of an exposed knob that is located adjacent a supporting structure in the cab, and a valve housing is mounted behind the supporting structure. A new structural base is permanently connected to the valve housing in an exposed position in the vehicle's cab. The base is normally accessible to the driver at all times, but it is thin enough so that it will not interfere with normal push/pull movement of the valve's knob. A rigid and generally hollow cover is adapted to be selectively suspended over and in contact with the structural base. The cover is sufficiently deep as to envelop the valve's knob in order to conceal it and render it inaccessible when the cover is suspended over the base. The cover is selectively removable from the base so as to permit the driver to remove the cover and thereby have access to the knob.

  • Patent number: 5328320
    Abstract: An apparatus adapted for attachment to the frame of a truck, usually within a bed of a conventional pickup truck. A generally planar base is rigidly attached to the truck frame with bolts. A platform is rotatably connected to the base with a pair of four-bar linkages, one on the right side of the platform and one on the left. The platform has a low position close to the base, and a high position that is typically 15 or 20 inches higher. A double-acting hydraulic cylinder is anchored at one end to the base and connected at its other end to the platform. Pressurizing the cylinder one way causes the platform to be raised and translated backwardly with respect to the base. Pressurizing the cylinder the other way causes the platform to be moved toward the base in a relatively slow and deliberate manner.

  • Patent number: 5197313
    Abstract: A locking apparatus that includes first and second structural elements that are adapted to be juxtaposed and positioned next to one another in a "locked" mode, and physically separated from one another when "unlocked." When in its locked mode, the locking apparatus is restrained against separation until a manual force is simultaneously applied to appropriate levers, ends of which are accessible on the exterior of the apparatus.A plurality of levers are mounted on the first of the two structural elements for rocking movement about a pivotal axis carried by the first element. Each lever has a first end that protrudes externally of the apparatus, and a second end that is sized and shaped so that it may be engaged with a lip surrounding an associated aperture in the second structural element.

  • Patent number: 4983030
    Abstract: An eyeglass construction characterized by having a conventional frame with a pair of rim supports for receiving and holding a pair of lenses. The rim supports have a plurality of fixed prongs distributed around the rims at points that are remote from a bridge that connects the tops of the two rim supports. Affixed to the frame, usually near the bridge, is a retaining mechanism that includes a housing having two open ends. A wire-like member is adapted to protrude out of each of the two open ends of the housing for a distance which is adequate to cooperate with the fixed prongs for firmly holding the lenses in the rim supports. Whenever it is desired (or necessary) to replace one or both of the lenses, the appropriate wire-like member is retracted into the housing, such that the adjacent lens may be manipulated--usually by slightly rotating it--in order to free it from the rim support. The wire-like retaining member is biased in its extended position by a bias member having the characteristics of a spring.

  • Patent number: 4824000
    Abstract: An apparatus for dividing a pill into two portions (i.e., halves, quarters, etc.), such that one portion is immediately accessible and the second portion is captured for later use. The apparatus includes an anvil-like platform adapted to support a pill in a generally horizontal mode. A centering means is sized and oriented for positioning the pill on top of the platform in such a way that the pill is bisected by a cleavage plane, regardless of the size of the pill. The centering means preferably includes a pair of converging walls, with each wall lying in a plane that is substantially perpendicular to the plane established by the platform. A gap between the convergent ends of the two walls lies in the cleavage plane, and the gap has a width which is just sufficient to receive a movable blade. The blade may be moved between two major positions, with one being a raised (or retracted) position and the other being a completely lowered position.

  • Patent number: 4271549
    Abstract: A relatively small watercraft includes a pair of spaced and usually parallel pontoons. A personnel station extends generally between and above the two spaced pontoons. A structural frame of tubular members or bars supports the personnel station; the tubular members may be selectively connected to the pontoons, or the frame may be permanently connected to them. In one embodiment wherein the structural frame and the pontoons are only temporarily connected, a plurality of eye bolts and specially positioned slots are utilized so that the eye bolts need never be removed from the watercraft. (In this embodiment, there are no connecting pieces to ever get lost, even when the three main sub-assemblies of the watercraft are disassembled.) The eye bolts are aligned longitudinally with the slots for disassembly, and turned transversely to the slots to hold the tubular members to the pontoons. Dimples or recesses in the tubular members can be provided to inhibit unwanted rotation of an eye bolt.

  • Patent number: 4115670
    Abstract: An assembly of at least two single-pole, double-throw slide switches, with one of the switches being mounted 90.degree. with respect to the other switch. A movable plate is positioned above the two SPDT switches, and the movable plate has apertures or the like which engage the projecting arms of the two SPDT switches, whereby translating movement of the movable plate causes action of one or both of the SPDT switches. Appropriate springs are provided to bias the movable plate to a centered, rest position at all times. Hence, movement of the movable plate as a result of some manual force may affirmatively generate any one of eight distinct signals. The centered rest position of the movable plate may also be considered as a signal-generation position, such that nine distinct bits of information may be communicated through the manual manipulation of a single knob that is connected to only two SPDT slide switches.
