  • Patent number: 4465216
    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.

  • Patent number: 4463912
    Abstract: Disclosed is a dispenser for toilet tissue and other similar roll material having a hollow core. The dispenser has a storage container which allows a plurality of rolls to be stored in an end-to-end stack arrangement. The lowest roll can be dispensed by a user through a side opening in the storage container. When the lowest roll is completely used, the user can discharge the roll core by pulling a slide plate outwardly to align an aperture in the slide plate with the used core. The core also drops through a core opening in a pivot plate immediately below the slide plate. The next roll of tissue drops to the slide plate and is supported thereon because it is larger than the core aperture.The dispenser is filled by releasing a lock means and rotating the storage container into a horizontal position.
