Abstract: A boat lift includes a base mounted on land adjacent to a body of water, a swinging frame mounted to the base by a first swinging coupling, a boat-supporting frame mounted to the swinging frame by a second swinging coupling, and an actuator for causing the swinging frame to swing relative to the base about the first swinging coupling. Thus, the boat-supporting frame moves upwardly and inwardly to a boat-storage position, or downwardly and outwardly to a boat-launch position, depending upon the direction of swinging motion of the swinging frame. The swinging frame and the boat-supporting frame together form a walkway arranged for providing access between the shoreline and the boat-supporting structure when the boat-supporting frame is in its boat-launch position.

Abstract: A boat drive system includes a transmission unit, a propeller shaft, and an auxiliary drive unit for driving the propeller shaft in the event of a failure of the main engine and/or the transmission unit. The auxiliary drive unit includes a housing slidably supported by the transmission unit, and the housing carries a motor and a drive sprocket driven by the motor. The drive sprocket is hollow, to enable the propeller shaft to extend therethrough. The drive sprocket includes axially facing teeth which are engageable with axially facing teeth of a coupling sleeve affixed to the propeller shaft.

Abstract: A lift truck, especially for lifting boats, includes a self-propelled main frame having a pair of parallel rails extending in a fore-and-aft direction. The main frame is supported by front drive wheels and rear castor wheels. A mast is movable forwardly and rearwardly on the rails and carries a lift assembly that can pivot about a transverse axis. The lift assembly includes a pair of lift arms each having vertical and horizontal portions. The vertical portions are mounted to swing about respective fore-and-aft axes, and are horizontally movable toward and away from one another for increasing or decreasing the distance between those axes. The main frame does not carry a counterbalance weight, but rather has a latch which grips a ground-mounted anchor for anchoring the rear end of the main frame during vertical movement of the lift assembly.

Abstract: An enclosure comprises a plurality of modules arranged in a longitudinal direction. Each module comprises a pair of longitudinally spaced frames separated by wall panels extending along the sides and top of the enclosure. The frames are secured together by tensioned cables which press the frames together and hold the wall panels within channels formed in the frames. Two of the top wall panels are inclined at an oblique angle and have upper and lower longitudinal edges which bear against corresponding edges of adjacent wall panels. Portions of the inclined wall panels and/or adjacent panels are bent to assure proper engagement therebetween. Removable locking plates prevent removal of the inclined wall panels.

Abstract: A coin-operated latch mechanism for a newspaper rack includes a coin-receiving mechanism into which coins are deposited. A coin-return mechanism is provided which, when depressed, swings the coin-receiving mechanism to a position in which the outlets of the coin slots overly a coin-return diverter. The coin-return diverter is normally disposed in a coin return mode and is moved to a coin retention position in response to the opening of a door of the rack. A key-actuated wall of the rack is mounted on hinges which permit a simplified removal of the wall from the rack. The key-actuated wall includes a latch which enables the wall to be closed and relatched without the use of a key.

Abstract: A display container for publications comprises a housing, a door swingably mounted to the housing, and a spring for biasing the door closed. The door comprises a sheet of transparent flexible material anchored along an inner edge thereof to the housing so as to be flexibly swingable in cantilever fashion. The spring comprises a coil spring having outer and inner ends connected to an interiorly facing surface of the door so that movement of the door to an open condition elastically deforms the spring to bias the door closed. The spring bears against the door to be capable of holding a display publication which is inserted between the spring and the door.

Abstract: A knock-down newspaper rack includes side and rear walls defined by a sheet of metal which is bent along two vertical corners. The side and rear walls include horizontal flanges along their lower ends, the flanges extending inwardly and resting upon ground support legs. A front unit includes a frame and a door swingably mounted on the frame. The frame includes a pair of vertical rearwardly open channels which receive front vertical edges of the side walls. Those front edges are bent to create a firm frictional lock within the channels. A cover is positioned atop the housing and front unit. The cover includes a front edge formed as a rearwardly open channel to receive a forwardly extending horizontal upper edge of the frame to lock the cover to the front unit. Upper edges of the side and rear walls are bent inwardly, and the cover includes downwardly depending flanges which fit over, the outside faces of those upper edges to lie in frictional engagement with the side and rear walls.

Abstract: A newspaper display machine comprises a base frame forming therein an interior compartment, and an access opening communicating with the compartment. A self-contained module is provided for controlling the access to the compartment. The self-contained module comprises a casing which is securable to the base frame, a door pivotably carried by the casing, and a coin-actuated mechanism for enabling the door to be opened.

Abstract: A newspaper display machine has a container and an access door pivotably mounted to the container. The door includes a transparent window large enough to expose the full length and full width of a newspaper. A pair of pressure plates are pivotably mounted on the inside of the door for retaining a display newspaper against a rear surface of the window. Closure springs bias the pressure plates and access door to their closed positions. The container is provided with retainer openings which receive lower corners of the pressure plates when the pressure plates and the access door are all in their opened positions, in order to hold-open the pressure plates and access door against the closure biases of the springs.

Abstract: A newspaper display machine includes a housing, a service access door mounted on the housing and carrying a coin-actuated unlocking device, and a paper access door mounted on the service access door. A locking mechanism includes a first lock for locking the service access door to the housing and a second lock for locking the paper access door to the service access door. A single key-actuated cylinder controls both the first and second locks for selective actuation. A pin which forms a horizontal hinge axis for the paper access door also forms a vertical hinge axis for the service access door. That pin is slidably removable from the housing to facilitate removal of the service access door from the housing. That pin, together with another pin plus two elements of the second lock, serve to support the service access door against forces imposed thereagainst when the paper access door is slammed shut.

Abstract: A newspaper vending rack is designed to be transported and stored in a disassembled format. The rack includes four side wall members that are accommodated within channels or grooves formed in each of the top and bottom members of the rack. The top and bottom members are held together, to thereby clamp the side wall members in place, by a pair of guide rods that support an elevator shelf and are pinned to the top member and bolted to the bottom member. One of the side wall members includes a frame supporting a pivotable door that provides access to the interior of the enclosure formed by the rack.

Abstract: An electronically controlled, coin-operated latch mechanism includes an inclined coin chute through which different size coins travel at different angles to provide an electrical connection between different coin detecting contacts. An electronic circuit is responsive to signals generated at the contacts to totalize and store the monetary value of deposited coins. When the stored value equals or exceeds a programmed price, an electromagnet is actuated to enable a hook to be pivoted away from engagement with a latching member. Subsequent movement of the released latching member causes deposited coins to be placed in a coin receptacle and resets the hook for subsequent latching.
