Abstract: A connecting system for connecting a first mesh sheet to a member comprising a housing member, a first loop portion, and a first pin member. The housing member defines a loop passageway, and the housing member is adapted to be rigidly connected to the member. The first loop portion is formed on the first mesh sheet and extends into the loop passageway. The first pin member extends through the first loop portion of the first mesh sheet such that a force applied to the first mesh sheet away from the housing member causes the first pin member to engage the housing member and the loop portion to inhibit movement between the first mesh sheet and the member. In one preferred embodiment, the member is a concrete panel. In another preferred embodiment, the member is a second mesh sheet.
Abstract: A boat-lift system adapted to move a smaller boat relative to a larger boat. The boat-lift system comprises a structural support, a lift structure, a pivot system, and an actuator assembly. The structural support is adapted to be rigidly connected to a transom of the larger boat. The lift structure defines a second pivot portion, an actuator portion, an extension portion, and first and second boat-engaging portions. The pivot system connects the first and second pivot portions to allow rotation of the lift structure between first and second lift positions relative to the structural support. Actuation of the actuator assembly causes the lift structure to move between the first and second lift positions. When the smaller boat is in a docking position adjacent to the lift structure, operation of the actuator assembly moves the lift structure to lift the smaller boat from the docking position to a first storage position.

Abstract: A diesel hammer system for driving piles. In one form of the invention, a control pinion is attached to a cam member employed to adjust the volume of a fuel portion of a pump chamber. A control rack is arranged to engage the control pinion such that linear movement of the control rack is translated into rotational movement of the control pinion. A hydraulic cylinder assembly is provided having a control housing and a control piston. The control piston is attached to the control rack such that linear movement of the control piston is transferred to the control rack. Hydraulic fluid is introduced into the control housing to cause linear movement of the control piston. Conventional hydraulic controls may be used at a remote location to introduce hydraulic fluid into the appropriate portions of the control housing chamber. In another form of the invention, indicia are formed on a housing of the variable fuel pump to allow an operator to see the setting of the fuel pump.
Abstract: A dump truck system comprising a vehicle, a trailer assembly, and hitch assembly. The trailer assembly comprises a trailer frame assembly. The hitch assembly connects the support member to the vehicle. In one embodiment, the trailer assembly further comprises a support member attached to the trailer frame assembly and a suspension assembly arranged between the support member and the trailer frame assembly. The suspension assembly resiliently opposes transmission of shocks from the trailer frame assembly to the vehicle as the vehicle pulls the trailer assembly. In another embodiment, the vehicle comprises a vehicle bed having a gate assembly movable between open and closed positions, the a trailer frame assembly is operable in a selected one of a rail configuration and a notch configuration, and a trailer bed is adapted to be supported by the trailer frame assembly. The trailer assembly is operable in a tow configuration a transfer configuration.
Abstract: A modular pile system. The pile system comprises first and second cylindrical plastic pile members and a detent system. Each of the pile members has an upper end and a lower end. The detent system connects the upper end of the first pile member to the lower end of the second pile member. The detent means allow the second pile member to be displaced into a desired position relative to the first pile member but substantially prevent relative movement between the first and second pile members when the second pile member is in the desired position.
Abstract: A clip for sheet materials comprising a clip member and a collar member. The clip member is made of resilient material such that the clip member may be deformed from a normally open configuration into a closed position. The clip member defines first and second finger portions that do not engage each other when the clip member is in the open configuration and engage each other when the clip member is in the closed position. The collar member defines at least one latch portion, a lever portion, and a housing interior. The collar member is made of resilient material such that applying a force to the lever portion causes the collar member to deform from a normally engaged configuration to a disengaged configuration.
