An electric linear actuator includes a housing extending along a longitudinal axis, the housing configured to be coupled to a first component. A spindle is provided in the housing and extends along the longitudinal axis from a proximal end to a distal end. A motor is coupled to the proximal end of the spindle and is configured to rotate the spindle. A spindle nut is received on the spindle and is movable with respect to the housing along the longitudinal axis in response to rotation of the spindle. The spindle nut is configured to be coupled to a second component. A one-way bearing prevents back-drive of the motor when an external load is applied to the second component while the motor is not provided with electrical power.

A vertically adjustable pedestal for a boat accessory includes a hollow outer column and an inner column positioned within the outer column. The inner and outer columns are longitudinally slidable with respect to one another. A plate is captured between the inner and outer columns. The plate is laterally adjustable to create a frictional force between the inner and outer columns that prevents lateral movement therebetween. One of the inner and outer columns is configured to be coupled to a supporting surface of a boat. The other of the inner and outer columns is configured to be coupled to the boat accessory. A lifting actuator is provided with an extender rod having an anti-buckling plate provided thereabout. The lifting actuator raises and lowers the inner or outer column that is coupled to the boat accessory.

A trolling motor assembly includes a base and an attached cradle. A transmission housing is coupled to the base by a pivot pin defining an axis about which the transmission housing pivots. A shaft is supported by the transmission housing and moves relative to the transmission housing in a direction which is parallel to a central axis of the shaft. The shaft is also rotatable with respect to the transmission housing about the central axis. A thrust motor is attached to and moves and rotates with the shaft. The assembly is movable from a deployed position, in which the shaft central axis is aligned vertically, the transmission housing is locked in an upright position, and the thrust motor is below water, to a stowed position, in which the shaft central axis is aligned horizontally, the transmission housing is pivoted onto its side, and the thrust motor rests in the cradle.

An ambulance cot having a wheeled base, a horizontally oriented patient litter support disposed on the base and having an elongate guide extending lengthwise thereof. A support mechanism is provided for supporting the patient litter support for vertical movement relative to the base while being maintained in the generally horizontal orientation. A device for selectively locking the patient litter support at selectively different vertical elevations is provided.

A sprinkler head assembly has a stamped mounting element for supporting a thermally activated triggering member in a sprinkler head assembly, and a method forms the same. The mounting element comprises a central base including a seat for supporting the triggering member. A first pair of arms, having a longitudinal extent, extend from a first face of the base at an angle less than 180 degrees. A second pair of arms, having a longitudinal extent, extend from the first face of the base at an angle less than 180 degrees. The longitudinal extent of at least one of the arms is greater than the longitudinal extent of the other arms to define a recess for cooperatively engaging the sprinkler head assembly. The mounting element is stamped from generally planar stock to form arms having varied lengths and, thus, create a saddle-shaped recess that slidably mounts on a frame of the sprinkler head assembly. The mounting element is preferably formed by progressive stamping techniques and accommodates various dimensions and tolerances of the sprinkler head frame and thermally responsive triggering member.

A sprinkler head includes a powdered metal base including external threads for threadably engaging a water pipe, and a stamped metal frame attached to the base. The base defines a passageway for receiving water from the water pipe and an opening to the passageway. The powdered metal base is infiltrated with copper or vacuum infiltrated anaerobic resin to provide a hydrostatically leak tight composition capable of withstanding 700 psi. A deflector is attached to the frame for distributing water dispensed from the opening. A circular plate or circular spring sealingly covers the opening, and a pip is engaged with the frame creating a space therebetween. A frangible bulb is positioned in the space between the Belleville spring. The frangible bulb is made of a temperature-sensitive material that fractures at a predetermined temperature and thus allows water pressure from water in the water pipe to unseat the spring and thus spray water. A capacitor discharge weld is shown for connecting the frame to the base and for connecting the base to the pip so that the frangible bulb is retained with a predetermined force despite dimensional variation in the frangible bulb.

An in-line check valve includes a housing defining a cavity with an inlet and an outlet, a removable seat attachable to the inlet, a piston movably positioned in the housing and including a seal that operably engages the seat, and a spring positioned around the piston for biasing the piston into engagement with the seat. The piston defines a surface impinged on by fluid flowing therethrough so that the differential pressure across the valve in a given flow range is less than the opening pressure. The housing defines a plurality of lugs which retain the piston within the housing and permit servicing of the seal.

In-line check valve

A check valve assembly adapted for use in a fire protection system includes a housing defining an inlet, an outlet, a seat and a chamber. A clapper or valve element is mounted within the chamber for movement towards and away from the seat. A parallelogram linkage supports the clapper. A pair of draw bars extend diagonally between opposed links. Each draw bar defines a stop. A coil spring encircles the draw bars and engages the stops. Expansion of the coil spring forces the draw bars apart and resiliently biases the clapper or valve element against the valve seat.
