Abstract:
An automated method and system to assemble and inspect tubing assemblies includes one or more coordinate tables with each table having a plurality of robotic fixtures mounted for movement on the table. The robotic fixtures are controlled by a computerized control system to move to predetermined positions on the table surface, and tubing holders on the robotic fixtures are controlled to receive portions of a bent length of metal tubing to inspect and assemble the portions of tubing.
Abstract:
Apparatus for aligning two members (28) includes a first section (63, 67) and a first coupling device (70, 71) for coupling first section (63, 67) to one of the members (28). A second section (61, 62) is provided and a second coupling device (71, 70) to couple the second section (61, 62) to the other of the members 928). A third coupling means (67, 68) movably couples the first and second sections together to facilitate relative movement between the first and second sections to align the two members (28).
Abstract:
A lightweight, portable clamping device assists in holding and reforming pipes in piping systems. The clamping device comprises a pair of semicircular clamp halves which are placed on the abutting ends of out-of-round pipe. The clamp halves are drawn together by tightening bolts on either side to align and reform the ends of abutting pipes. The clamping device can also be used to shape and hold the end of a single piece of pipe. A plurality of access ports around the perimeter of the device allow a welder to tack weld the ends of abutting pipes prior to welding.
Abstract:
A fixture for aligning clamping pipes end to end to enable joining the pipes by welding includes a collar circumscribing one of the pipes and circumferentially spaced arms extending outwardly from the collar and then coaxially with the pipes. Pipe damps are supported by each of the arms at approximately 120 degrees intervals about the pipe. The stems of the clamps are supported by the arms such that proper orientation of the clamping shoes and guide members is assured. Furthermore, an extension of the stem which projects between the pipes and carries an inner guide member for engagement with the inner circumferential surface of the pipe has a differential thickness such that the pipes are initially separated by a predetermined thickness by engagement of the pipes with the necked portion of the extension for tack welding. After tack welding is complete, the stems are rotated 90 degrees, thereby bringing a narrower dimension of the necked portion into registry with the gap between the pipes, permitting withdrawal of the stems.
Abstract:
A centering apparatus for use by the laying of heavy tubes of relatively large dimensions, especially for centering the spigot end of a tube relatively to the socket end of a positioned tube, and comprising a clamping device with at least two interconnectable members adapted to be attached to the socket end, and a guiding device for slidable guiding of the spigot end into the socket. The guiding device includes a number of brackets mounted to the interconnectable member enclosing the lower peripheral part of the socket end, which brackets project axially from said member and have guiding surfaces forming a chute onto which the tube to be laid down can be lowered to be pushed in centered position towards the adjacent tube end.
Abstract:
A method and apparatus for forming a drawn container from a metallic blank are disclosed wherein the blank is drawn over the outer surface of a stationary forming ring by an annular forming die to form a tubular wall portion which is thereafter completely redrawn by a forming punch in co-operation with a forming die, a reverse redrawn annular wall portion of the blank being positioned for engagement by a curling ring to form an inwardly curled rim at the peripheral edge of the open end of the container.
Abstract:
The specification discloses an improved system for projecting and utilizing a light beam as a reference line for construction purposes. The system includes a light beam projection device mounted in a housing. A light path compensator is positioned within the housing and intercepts the beam of light emitted by the light beam projecting device and automatically corrects slight deviations of the light beam from true horizontal. A vertically adjustable leg is attached to the front end of the housing and a horizontally pivotable leg is attached to each side of the housing near the rear end of the housing to enable leveling and centering of the housing in a conduit or positioning and leveling on any surface. Structure is controllable from the rear of the housing to deflect the light beam in a vertical plane to vary the grade of the beam projected by the device. An indicator, readable from the rear of the housing, is provided for indicating the grade at which the light beam is projected. Structure is corrected between the support legs and housing for rotating the housing in a horizontal plane to provide azimuthal adjustment of the light beam projected therefrom.
Abstract:
This disclosure describes a method and apparatus for laying a pipeline in which the pipes are aligned along a preselected path with a collimated light beam, preferably according to the methods of U.S. Pat. Nos. 3,116,557 and 3,279,070. Air is forced through the pipeline in a helical spiral to prevent gases from building up within the pipeline as the pipes are being laid. A blower unit coupled to an outlet nozzle having a clamp for clamping the nozzle to the pipe at an angle to the longitudinal axis of the pipe is provided for this purpose.
Abstract:
A prefabricated modular rough plumbing unit for use in residential building construction is described. The rough plumbing is incorporated in a section of interior wall framework that can readily be integrated with the framing carpentry during construction. Plumbing waste piping is so arranged as to permit direct connection with plumbing fixtures such as bathtubs and water closets installed at the same floor level as that of the modular wall section, thereby obviating any requirement for below the flooring waste or soil piping installation prior to installation of the modular unit.
