Abstract: A device to transfer bodies along a path between the work positions on an assembly machine having a table and feed means for delivering bodies in a row, the device comprising a matrix bar extending above and parallel to the table of the machine on one side of the path of the bodies, the bar being carried by a lever mounted on a pivot and the bar having in at least one longitudinal edge and at regular intervals cut-outs whose profile is adapted to the periphery of the bodies; a rake constituted by a shaft extending parallel to the matrix bar on the other side of the path of the bodies and carrying a plurality of teeth spaced along the shaft with the same spacing as the cut-outs in the matrix bar, the shaft being mounted in bearings fixed on the machine for lengthwise translatory movement through advance and return strokes and for rotational movement about its longitudinal axis; a straight edge overlying the shaft, the straight edge being positioned in the same plane as the matrix bar and extending parallel the

Abstract: An apparatus is described for controlling the sequences of operations executed at the various work stations. At each work station there is provided detecting means arranged for detecting the correct completion of an operation, e.g. the correct positioning of a part in a support such as a case for making a cartridge, and generating a fault signal when the operation is not correctly completed. The fault signal is written into shift register means and shifted in response to a timed control signal, the successive states of this shift register means being compared with a reference signal representing the number of steps along the path between that work station and the next. When the state of the shift register means is coincident with the reference signal, an inhibit signal is produced for inhibiting the operation at at least one next work station.

Abstract: A priming chamber for a cartridge comprising a cylindrical tubular body one end of which is closed by a bottom formed with vent holes arranged around an axially and inwardly extending pressed part forming an anvil, the anvil being of tapered shape having two integral parts of which the lower part is fixed to a flat portion of the bottom of the tubular body, whereas the upper part terminates in an upper outer flat end.
