ABSTRACT:
In a rod cement feeding apparatus, the rod passes between two plates, pivoted to one another, each plate having a semi-cylindrical groove, so that the two grooves for a substantially cylindrical passageway for the rod. The surfaces of the plates in which the grooves are provided are, over most of their length, spaced apart by projections, so that opposed slots are formed which extend into the passageway for the rod. Projecting into one such slot is a spring-urged jaw which co-operates with a fixed jaw which projects into the other slot, the jaws being moved lengthwise of the passageway by a pneumatic cylinder arrangement. As the jaws are moved in one direction, the spring-urged jaw tends to bite into the rod so that the rod is fed with the jaws during their advancing movement, while when the jaws are moved in the opposite direction the rotatable jaw releases its grip so that there is no tendency for the rod to be fed in the opposite direction. In the event of a jam in the passageway or slot(s), which thus prevents the rod from being fed, it is merely necessary to unclamp the plates and pivot them apart to gain access to the passageway for cleaning purposes.
