  • Patent number: 5712429
    Abstract: A pressure instrument for connection to a process line including a gland having an interior passageway, a body connected to the gland and having a fluid line extending therethrough in fluid communication with the interior passageway of the gland, a pressure-responsive instrument connected to said fluid line, and a filter disposed in the interior passageway of the gland so as to prevent particles from passing from the instrument to the process line. The body has a pilot formed at one end of the body so as to be received within an end of the gland. The body is welded to the gland rearwardly of the pilot. The filter is positioned within the interior passageway of the gland forward of the pilot of the body. The pressure-responsive instrument is a bourdon tube having an interior in fluid communication with the fluid line.

  • Patent number: 4451223
    Abstract: An improved corner finishing tool for applying mastic along a wall joint and having a container that defines a cavity open in two convergent and substantially perpendicular planes, said cavity being bordered by surfaces that converge peripherally of said cavity, said container means comprising a pair of rigid retainer plates joined together by a pair of spring loaded hinges or fasteners and biased to a position of resilient flex. A pair of lever arms pivotally secured to an edge portion of the retainer plates and pivotally joined together at one end are acted upon by leaf springs which engage the lever arms at selected positions relative to the pivotal connection for adjusting the resilient flex between the pair of retainer plates. Mastic material is fed into the cavity through a socket bracket that is mounted to one of the retainer plates to which there is also mounted an alignment wheel.

  • Patent number: 4358337
    Abstract: A tape applicator and mastic dispenser for dry wall taping comprising a holder for a replaceable cartridge, means for forcing mastic material from said cartridge through a discharge outlet onto a tape, tape advancing means for feeding a tape from a supply roll beneath the discharge outlet, a roll for applying a mastic coated segment of tape onto a wall joint and means connecting the roll to the tape advancing means for positioning the roll in retracted or tape supporting position by actuation of the tape advancing means, whereby the pressure roll is retracted as tape is advanced beneath the discharge outlet and selectively positionable in front of the dispenser for supporting and applying mastic coated tape to a wall joint.

  • Patent number: 4116604
    Abstract: Improvements in corner finishing tools for applying mastic material along a wall joint and comprising an improved means for adjusting the resilient flex between integral sides of a mastic retainer plate; an improved retainer plate having elongated interior pockets formed directly in front of a pair of doctor blades to receive and store mastic material and to collect small foreign particles, and baffle plates to direct the flow of mastic material; and an improved means for supporting the tool including a pair of side rollers rotatably mounted peripherally of an interior mastic cavity.

  • Patent number: 4032283
    Abstract: A corner tool for applying mastic material to an external corner formed by two walls which come together at approximately 90.degree., said tool comprising a retainer for mastic material that defines a cavity open in two convergent and substantially perpendicular planes, including a pair of slotted screed plates that extend substantially perpendicular to each other and transverse relative to the external corner, and means for positioning the mastic retainer relative to the external corner to maintain the slotted plates in contact with the two walls forming the corner while positioning the cavity in open-spaced relationship to the walls.

  • Patent number: 3932101
    Abstract: A corner finishing tool for applying mastic material along a wall joint comprising an angular retainer plate having a pair of integral sides resiliently joined at a corner, a pair of L-shaped rigid frame members secured thereto, one side and frame member being resiliently movable relative to the other side and frame member while together defining a cavity reservoir for mastic material, and a wheel having substantially conical side surfaces that converge to a center rim. The corner finishing tool also provides means for setting the L-shaped rigid frame members to a preset position under an adjustable resilient biasing force.
