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.

Abstract: The paper advance mechanism disclosed herein comprises two essentially identical paper-engaging devices, one fixed, one driven, which cooperate to incrementally advance the paper in a hand-held printing calculator. Each device includes a tapered cavity enclosing a roller which engages the paper as it passes therethrough. The position of the roller in the cavity determines whether that device slidably or non-slidably engages the paper and the position of the roller is determined by the movement of the paper itself. The paper-engaging devices alternately non-slidably engage the paper; when the driven device moves in one direction, it non-slidably engages and thus advances the paper as it moves, and the paper slides through the fixed device; when the driven device reverses direction, it slidably engages the paper as it returns to the start of its travel and the fixed device non-slidably engages the paper to hold the advanced paper in position.

Abstract: A machine for attaching terminals to electrical conductors is disclosed wherein the bed and ram of an applicator are relatively movable together and apart and each carries a cooperating one of a pair of crimping dies to crimp a terminal onto a conductor when the ram and bed are moved together. A terminal feeding device supplies terminals to be crimped by the dies seriatim and in synchronism with relative movement between the ram and bed and a unidirectional coupling such as a chain connects the terminal feeding device to the ram so that the feeding device is actuated to supply a terminal when the ram retracts from the bed. A spring biasing device opposes operation of the unidirectional coupling to restore the feeding device for subsequent actuation. The cooperating dies and terminal feeding device are independently removably attached to the machine allowing independent replacement to accommodate specific conductor-terminal combinations.
