    摘要： An apparatus for selectively passing either a cordage pull line or ribbon-like tape pull line secured to a carrier plug through a conduit in response to a fluid pressure differential therein. The apparatus comprises a tubular conduit adapter having a wall defining a passageway for transmitting a fluid pressure therethrough, with one end of the adapter being positionable at the entrance end of the conduit and the other end of the adapter being attachable to a source of fluid pressure. A pull line entrance extends through the wall of the adapter for selective introduction into the passageway of either the cordage or tape pull line without undue loss of fluid therethrough, and comprises a first opening closely conforming to the cross-sectional configuration of the cordage pull line, and a second opening closely conforming to the cross-sectional configuration of the tape pull line. In one disclosed embodiment, the two openings are spaced, and provision is made for selectively covering either one or both of the openings. In a second embodiment, the two openings have portions thereof coinciding such that the total area of the two openings is less than the sum of their individual areas. The second embodiment also includes a cover hingedly mounted adjacent the two openings to selectively close the same.

    摘要： A gas operated line throwing gun for casting a line package across a relatively non-accessible area such that the trailing line end may be used to pull a heavier electrical line through the area. The gun includes a lightweight barrel defining a continuous tubular passageway, and one or more escapement ports are provided which extend radially through the barrel wall for releasing the gas pressure in the event the barrel is obstructed when fired, to thereby preclude bursting of the same.
