Abstract: A hands-free system for connecting and disconnecting a tool from an adjustable length extension pole. The system includes first and second slidably interconnected elongated members, a tool-holding assembly releasably coupled to the second elongated member, and a locking assembly disposed between the first and second elongated members. The relative sliding of the first and second elongated members can be selectively restrained by rotating the first and second elongated members relative to one another. The tool-holding assembly can be disconnected from the second elongated member by sliding the first and second elongated members together.

Abstract: An extension pole is disclosed for use with a paint roller tool. The pole and handle cooperatively provide a smooth flush connection and prevent relative rotation therebetween. In particular, an end portion of the extension pole comprises a locking mechanism that is designed to releasably interconnect the paint roller tool and the extension pole via operation of a button assembly on the extension pole. The locking mechanism includes a housing presenting a narrow outer surface defined along a circle coaxial with the pole and snugly received within the paint roller handle. A wide outer surface spaced radially outward from the narrow surface presents a key section, which when received within a recess extending inwardly from the rear end of the tool handle, cooperates with the handle to prevent relative rotation between the tool and extension pole.

Abstract: An adjustable height sprinkler apparatus having three tubular portions telescopically received within each other. The base portion is buried vertically in the ground and connected to a source of water pressure at the lower end, the upper end being adjacent the earth's surface. A second tubular extension member is vertically positionable by telescopic displacement relative to the base member and includes a coupling for sealably retaining the extension member in the selected vertical position. A third tubular pop-up member is telescopically positioned in the extension member and slidable downwardly by gravity and displaced upwardly when water pressure is applied to the sprinkler, the pop-up member having an enlarged diameter portion at the upper end with means for attaching a sprinkler head.

Abstract: A corrosion proof meter riser for attachment to a subsurface polyethylene pipe carrying fluid at high pressure, which comprises a length of selected polyethylene tubing adapted to be attached at a first end to said polyethylene pipe, and heat seal means and cylindrical seal for attaching the second end of the polyethylene tubing to a first end of a selected length of fiberglass tube of substantially the same radial dimensions. The fiberglass tube is molded with a circumferential ridge near its second end. A riser body, comprising a metal pipe of suitable interior diameter has a coupling at one end which is screwed to the pipe. The coupling has an internal shoulder which cooperates with the ridge on the outer surface of the fiberglass tube, so that when the joined fiberglass and polyethylene tubing is inserted into the body, the ridge rests on the shoulder and can be locked in position by a nut to seal that end of the body.

Abstract: A safety valve for pressure fluid flow lines and which may be utilized in combination with a punch tee, said valve being responsive to pressure differentials acting thereacross for automatically closing to preclude accidental loss of pressure fluid from the line. The valve comprises body means adjustably secured in communication with the pressure fluid of the flow line, valve seat means provided on the body means, cage means carried by the body means, ball means loosely disposed in the cage means to provide a normally open position for the valve and responsive to pressure differentials thereacross for automatically engaging the valve seat to provide a closed position for the valve, locking means adjustably disposed in the proximity of the body means for providing a predetermined positioning or setting for the body means for calibrating the pressure responsive sensitivity for the ball means, and means for selectively opening the valve against said closing pressure differential.

Abstract: Improvements in a ball-type shut off valve including a resilient seating means whereby an O-ring is included in conjunction with the seat to provide both metal-to-metal and metal-to-O-ring seating. Also included is a removable ball carrying means carried by the actuator arm, whereby straight through assembly of the actuator arm may be made directly through the valve operator opening thereby reducing the possibility of damaging seals on assembly and disassembly.
