  • Patent number: 4092928
    Abstract: Traveling support apparatus for supporting welding device or other apparatus for peripheral travel about a pipe. The support apparatus utilizes endless belts disposed around paired wheels at opposite sides of the apparatus to propel the apparatus along a track. The endless belts are pivotally supported for equal pressure engagements with the path along which the support apparatus travels. The support apparatus engages opposite sides of a track in the form of a strip or band spacedly surrounding a pipe to support a frame which is held firmly against movements toward or away from the track so that the supported apparatus is reliably held in position with relation to the pipe.

  • Patent number: 4088007
    Abstract: Pipe bending mandrel wherein oppositely disposed pipe wall engaging elements are connected to a drive unit at one end by toggle elements permitting inward and outward movements of the pipe wall engaging elements, and wherein said pipe wall engaging elements are connected to a longitudinal axial shaft of the drive unit by plural axially spaced toggle elements which move the pipe wall engaging elements inwardly or outwardly upon reciprocating movements of the shaft in opposite directions.

  • Patent number: 4069088
    Abstract: Pipe wrapping apparatus of the so-called hand-wrapping type, having a rotating ring structure which carries spindle apparatuses, each carrying a roll of pipe wrapping tape. The apparatus includes take up spindles for accumulation of the backing stripped from tapes which have backing, and includes brake devices for controlling the tension at which the tape is wound onto the pipe. While the apparatus is of the so-called hand-wrapping type, it may be power driven. The apparatus also provides for applying a coat of primer or other precoating material onto the pipe prior to the application of the tape. A notable feature of the invention is the provision of self-balancing spindles through the use of which the tape is consistently applied to the pipe without wrinkles or other misalignments of the tape and with uniform overlap of courses.

  • Patent number: 4067450
    Abstract: Pipe handling apparatus for pipe laying barges, sometime called lay barges, wherein pipe is lifted from an incoming pipe conveyor to a transverse rack, from one rack position to another, and from the rack to the pipe line-up conveyors, by a series of pivotal lifting means which lift, move, and deposit the pipe without impact or shock, whereby the pipe and any concrete or other coating on the pipe is not damaged. In addition to the novel pipe transferring means, the invention presents a novel universally adjustable line-up conveyor apparatus.

  • Patent number: 4027522
    Abstract: Internal mandrel for use in bending the ends of pipes, wherein a hydraulic cylinder actuates a system of levers and toggles to apply force across the interior of an end of a pipe in the direction in which the pipe is to be bent to prevent distortion and collapse of the pipe during bending adjacent to its ends.

  • Patent number: 4027349
    Abstract: Apparatus for brush-cleaning the interiors of pipes, wherein rotative brushes are carried by a rotative carrier plate. The brushes are rotated by air motors, and rotate at very high speeds. The brushes are spring-loaded to consistently bear against the inside of the pipe wall, and are disposed at a small angle from radial which results in reduced brush wear and more efficient pipe wall cleaning.
