ABSTRACT:
In a textile beam consisting of a pair of heads threaded onto the ends of a cylindrical barrel, relative rotation between a head and the barrel is restrained by providing on the head a plurality of screws which extend parallel to the axis of the barrel and engage threads on the head, and which are turnable into abutment with a thrust ring carried by the barrel, thereby creating an axial separating force between the head and the barrel which increases the friction in the threads connecting these two parts together.
