Abstract

Holder for a threading die. A die holder is provided for threading elongated items of circular cross section, particularly pipe or rod, which can utilize dies of either hexagonal or circular external contour, which can be arranged to reach otherwise awkward places, which can be rotated either by a wrench or by handles and which under certain conditions of use permits a long article such as rod material to pass entirely therethrough. A generally tubular body part has a recess, preferably hexagonal, in one end thereof for the reception of either a hexagonal or a circular die. If a circular die is used, same can be held in position by a set screw. The other end of said body member is externally contoured for receiving a wrench and has an end opening of normally rectangular cross section which is on a common center with the axis of said die. Thus, said die holder can be rotated by a wrench either directly on said last-named end thereof or through an extension inserted into said rectangular opening. There is also provided cross arms which may be threaded or pressed into position radially of said die holder for effecting rotation thereof if preferred. If the die holder is rotated either by a wrench or by said cross arms, same may be used to thread a rod and the rod may then project through said rectangular opening.

In a device for receiving and rotating a threading die, the combination comprising:

an elongated rigid body part having an elongated opening extending centrally therethrough, said elongated opening including an elongated central opening portion terminating at the opposite ends thereof in first and second end opening portions disposed adjacent the opposite ends of said body part;
said first opening portion being disposed adjacent and opening outwardly through one end of said body part, said first opening portion being bounded by a plurality of circumferentially spaced, inwardly facing flat walls which define a hexagonal die-receiving opening shaped for reception of a threading die therein;
said second end opening portion being disposed adjacent and opening outwardly through the other end of said body part, said second opening portion being bounded by a plurality of circumferentially spaced, inwardly facing flat walls which define a substantially rectangular extension-receiving opening shaped for the reception of a rectangular driving extension;
said body part adjacent said other end thereof being provided with at least one pair of opposed external flats for the reception of a wrench, said flats being substantially radially aligned with the walls defining the extension-receiving opening;
said body part also having a pair of handle openings formed radially therein on substantially diametrically opposite sides thereof, said handle openings being disposed intermediate the opposite ends of said body part and projecting radially inwardly from the outer peripheral surface thereof;
a pair of elongated rodlike handles having the inner ends thereof releasably secured within said pair of handle openings, said handles projecting radially outwardly of said body part in substantially diametrically opposite directions;
said die-receiving opening, said wrench section and said extension-receiving opening all being symmetrical about the central longitudinal extending axis of said central opening portion;
whereby a die held within the die-receiving opening of said body part may be rotated simultaneously with said body part as desired by manual application of force to said handles, by manual application of force through a wrench onto the flats of the wrench section, or by manual application of force through an extension to the walls defining said extension-receiving opening.
