ABSTRACT:
A straight line shear has a pair of carriages which support opposed pairs of shear blade assemblies. These carriages are displaceable to shear gobs from molten runners of glass. Each shear blade assembly can be adjusted relative to its carriage, in the direction of carriage displacement, and to this end shear blade assembly guide pins are slidingly received in carriage bushings. These bushings have one axial portion which is press fit into a carriage bore and the remaining portion has an enlarged threaded interdiameter which extends the bushing and hence its life and which enables the bushing to be pulled from its bore by a hand tool having a threaded socket.
