    Abstract: A switchbox for monitoring the position of a manual quarter-turn valve has a housing mountable to the valve to be monitored/controlled. A handle-driven shaft extends through the housing, with one end of the shaft couplable to the valve stem such that movement of the shaft moves the valve stem. One or more shaft position sensor switches interact with a cam on the shaft to signal shaft position and/or provide control signals. A plate coupled to the shaft articulates within a recess on the surface of the switchbox to limit motion of the valve to an operable range, such as between full ON and full OFF. The switchbox has a pair of lock tabs with lock apertures. A lock aperture in the plate is alignable with the lock tab apertures to receive a pin or padlock for locking the valve in a selected position. A potentiometer can be utilized in place of a switch as a shaft position sensor. The switchbox may be used with an original or new handle and may feature detents to allow a range of valve settings.

    Abstract: A faucet handle includes a safety lock. The safety lock includes a latch that is manually movable between an engaged position and a disengaged position. The latch is adapted to engage an associated catch when the latch is in its engaged position. The safety lock also includes a primary lock element that moves between a locked position and an unlocked position. The primary lock element prevents movement of the latch from its engaged position to its disengaged position when the primary lock element is in its locked position. The primary lock element allows movement of the latch from its engaged position to its disengaged position when the primary lock element is in its unlocked position. A faucet including the handle requires three steps to dispense liquid: (i) movement of the primary lock to its unlocked position; (ii) movement of the latch to its disengaged position; and (iii) movement of the handle to its liquid dispensing position.

The knob includes an "L" shaped locking member which conforms to the contour of the knob, and is adapted to pivot towards the valve body and lock the valving element out in the "in service" position. This pivotal member includes an indicating surface visible from the front when the valving element is locked in an "in service" position. The locking member is comprised of a fusible material selected to yield at a predetermined temperature so as to return the valve to an operating mode responsive to the pilot fluid pressure.

  • Patent number: 4304256
    Abstract: A torque transmitting assembly for effecting rotation of a valve member such as a butterfly valve is hermetically sealed to the valve housing. It includes a rotor member having a plurality of circumferentially spaced permanent magnets of opposite polarity and a driver magnet assembly having a like plurality of circumferentially spaced permanent magnets of opposite polarity facing the magnets mounted to the rotor. The two sets of magnets are separated by a stainless steel separator which hermetically seals the rotor. The driver magnet assembly is rotatable about the separator so that magnetic coupling forces effect a following rotation of the rotor and hence of the valve member. A magnetic indicator may be used to identify the rotational position of the rotor. The entire assembly is hermetically sealed and no packing is required. The assembly is especially useful to control a valve in a hazardous environment wherein no leakage of the fluid being controlled by the valve member is permissible.

  • Patent number: 4232817
    Abstract: An adjustment control for a thermostatic valve consists of a non-rotatable component to the valve on which is mounted a rotatable knob for setting the temperature control, the knob having a maximum rotation of about one revolution. A releasable auxiliary device is provided which is operable between the component and the knob at a predetermined intermediate rotational position of the knob to limit the rotation of the latter.

  • Patent number: 4225087
    Abstract: An automatic safety mechanism for airless spray equipment such as airless spray guns of the type having a trigger mechanism for actuating a gun spraying mechanism is provided. The safety mechanism comprises a lock mechanism for automatically locking the trigger mechanism in an "off" or non-spraying position upon full release thereof, including a locking member spring biased and disposed so that upon full release of the trigger mechanism the locking member is automatically operatively interposed between the trigger mechanism and hand-grip element of the spray gun to obstruct actuating movement of the trigger mechanism. The locking member is adapted for simple manipulation by the spray gun operator to disengage the lock mechanism and permit actuating movement of the trigger mechanism.

  • Patent number: 4216911
    Abstract: A high-pressure liquid-jet gun has a pistol-type housing provided with a valve having an actuation member displaceable between a closed position and an open position to release liquid from an end of the housing. A safety lever is displaceable on the housing between a safety position relatively far from the barrel of the housing and a use position lying against this barrel. A spring urges this safety lever into the safety position. A trigger is pivoted on the safety lever and has a formation which is engageable only in the use position of the safety lever with the actuation member. This trigger can be displaced in the use position of the safety lever between an advanced position with the formation engageable with the actuation member but with this actuation member in the closed position, and a drawn-back position with the formation pressing the actuation member of the valve into the open position.

  • Patent number: 4018292
    Abstract: The power tool has a drive motor and a turn-on switch device activatable for turning on the drive motor. A manual activator is mounted for swinging movement in a predetermined plane of motion and in a predetermined direction from a normal position to an activating position in which it activates the turn-on switch device. The manual activator is so arranged and configurated as to be depressible in the predetermined direction by a hand of the user of the power tool. A safety device prevents unintentional activator depression and includes a blocking structure. The blocking structure is mounted for swinging movement relative to the manual activator in generally the predetermined plane and in the predetermined direction from a blocking position in which it prevents activator depression to an unblocking position in which it permits such depression.

  • Patent number: 3931954
    Abstract: An improved petcock for controlling the flow of a liquid from a container. The petcock includes a housing comprising an inlet and outlet passage joined at their inner ends by a frusto-conic valve chamber opening external of the housing through a circular passageway. A valve member shapped to conform to the walls defining the valve chamber and circular passageway and positioned therein so as to provide sliding contact therewith when the valve member is selectively rotated. The valve member includes a bore through its base portion for passing liquid when aligned with the inlet and outlet passage and restricting fluid flow when misaligned. Sealing means is provided for sealing the housing to the tank, between a portion of the valve member and the valve chamber and between the circular portion of the valve member and an outer housing cover. Locking means is provided to selectively lock the valve member in either an "on" or "off" selected position.
