text: Pneumatic cord threading apparatus for threading a wire pulling cord through an electrical conduit, comprising, a blower having an outlet through which the blower forces air at a high rate under pressure, a flexible air supply hose connectable with said blower outlet to receive air under pressure from the latter, a tubular air supply fitting defining an internal air passage for transmitting air therethrough, said fitting having a generally right angle bend in the medial portion thereof and two legs of materially unequal length extending from the bend, the outer end of each leg being dimensioned to fit into the outlet end of said hose and having means encircling the adjacent end of said air passage to form a seal between the latter and the outlet end of the hose, a centrally open sealing ring shaped and dimensioned to fit in detachable encircling relation to the outer end of either of said fitting legs to form a seal therewith, said sealing ring defining an outwardly facing sealing surface of frusto-conical shape adapted to fit against and form a seal with the end of an electrical conduit when the sealing ring encircles the end of the fitting opposite from said hose, said fitting defining in said bend therein two apertures aligned with segments of said air passage in said respective fitting legs, each of said apertures opening outwardly to receive wire pulling cord from a supply of cord located outside the fitting and hose and supported independently of the fitting and hose, each of said apertures opening inwardly into the fitting to pass wire pulling cord into said air passage to pass out through the end thereof aligned with the aperture, means for closing either of said apertures selectively to block the outflow of air therethrough while wire pulling cord'is moving in through the other of the apertures; a cord pulling plug including means for detachably connecting the plug to the free end of a wire pulling cord, extending from the outlet end of said air passage after passing from an external supply of cord into the air passage through the fitting aperture aligned withthe outlet end of the air passage; and said cord pulling plug being shaped to fit slidably vinto an electrical conduit to form a movable barrier to the passage of air through the electrical conduit past the plug so that the plug is movable by air under pressure from said fitting through an electrical conduit against 'one end of which said sealing ring on the fitting is temporarily pressed to effect threading through the electrical conduit of wire pulling cord connected to the plug and fed through one of said apertures into said air passage in the fitting from an external supply of cord.
text: Pneumatic cord threading apparatus for threading a Wire pulling cord through an electrical conduit, comprising, a tubular air supply fitting defining "an internal air passage for transmitting air therethrough, said fitting having a generally right angle bend in the medial portion thereof and two legs of materially unequal length extending from the bend, the outer end'of each leg being dimensioned to fit into the outlet end of an air supply hose and having means encircling the adjacent end of said air passage to form a seal between the latter and the outlet end of the hose, a centrally open sealing ring shaped and dimensioned to fit in detachable encircling relation to the outer end of either of said fitting legs to form a seal therewith; said sealing ring, when disposed in encircling relation to one end of the fitting which is used as the air outlet end thereof, defining a sealing surface extending radially outward from the fitting to be pressed against and form a seal with one end of an electrical conduit, said fitting defining in said bend therein two apertures aligned with segment of said air passage in said respective fitting legs and being dimensioned transversely to closely encircle wire pulling cord, each of said apertures opening outwardly to receive wire pulling cord from a supply of cord located outside the fitting, each of said apertures opening inwardly into the fitting to pass wire pulling cord into said air passage to pass out through the end thereof aligned with the aperture, means for clos ingeither of said apertures selectively to block the outflow of air therethrough while wire pulling cord is moving in through the other of'the apertures;
