Patent number: 4869766Abstract: A synthetic resin pipe which includes two identical complementary, extruded semi-cylinders joined by electromagnetic bonding along abutting longitudinal edges to form a smooth walled cylindrical pipe. In one embodiment of the invention, the smooth walled pipe forms an internal sleeve or liner within an external corrugated pipe having contiguous circumferential corrugations over its length, and having the troughs of the corrugations bonded to the outer surface of the internal sleeve.In the method for forming the pipe, two identical flat plastic sheets are extruded, then vacuumed formed into semi-cylinders each having radially outwardly projecting longitudinal flanges extending from opposite side edges thereof. A paste or dispersion containing ferro-magnetic particles is then applied to the flanges on the sides thereof adjacent the concavity of the respective semi-cylinder. The semi-cylinders are next arranged in registry to form a cylinder with the flanges abutting.Type: GrantFiled: January 18, 1985Date of Patent: September 26, 1989Assignee: The Lamson & Sessions Co.Inventors: Harold T.

Patent number: 4647074Abstract: A system of flexible conduit and fittings useful particularly, though not exclusively, for conveying, supporting and connecting electrical service cables and wires. The system includes a corrugated, synthetic resin conduit which is flexible and mechanically strong, connector sleeves for clampingly engaging sections of the corrugated conduit in end-to-end relation, and hanger sleeves for clampingly engaging the conduit and suspending it from a wall or similar surface. A novel electrical outlet box is provided and includes internally toothed conduit-receiving inlet fittings for securely engaging an end of the conduits in inlets to the box.Type: GrantFiled: March 7, 1985Date of Patent: March 3, 1987Assignee: Indian Head, Inc.Inventors: Harold T.

Patent number: 4578528Abstract: An electrical outlet box optionally having in combination therewith, a connector fitting for connecting a corrugated conduit to the box, the box having a back wall and at least one side wall of synthetic resin. A pressure removable plug is displaced out of the plane of the side wall so as to provide a precisely delineated zone of weakness surrounding the plug. When one preferred type of connector fitting is used in combination with the box, a wedge-shaped end portion of the fitting, having a relatively small surface area, is manually pressed against the pressure removable plug along a pressure zone immediately radially inwardly from the zone of weakness. This pops the plug out of the wall of the box, leaving a neat, smooth hole into which the connector fitting may be inserted by continued manual pressure applied thereto.Type: GrantFiled: July 29, 1983Date of Patent: March 25, 1986Assignee: Thyssen-Bornemisza, Inc., (TBG Inc.)Inventors: Richard J. Borsh, Robert W. Ripley, Harold T. Pate

The housing includes opposed, substantially parallel side plates separated by a vertical slot at their upper ends, and by a mechanism chamber at their lower ends. A blade element is pivotally supported between the parallel side plates, and carries a plurality of ratchet teeth along the lower peripheral edge, and a cutting edge disposed at the opposite side of the blade element from the ratchet teeth. Between the teeth and cutting edge, the knife element has an elongated, arcuate slot formed therethrough. An operating handle is pivotally connected to the housing at a side thereof spaced from the pivotal axis of the blade element. A pawl lever is pivotally connected to the operating handle and has a dog thereon positioned to ride over and operatively engage the ratchet teeth as the operating handle is pivoted.Type: GrantFiled: January 5, 1981Date of Patent: December 21, 1982Assignee: Indian Head Inc.Inventors: Glenn A.
