  • Patent number: 5722194
    Abstract: A weapon bolt has a bolt head which accommodates an axially slidable firing pin and which is rotatable and displaceable parallel to the barrel axis. A bolt handle is pivotally supported on an axle carried in a radial orientation by a control sleeve which is slidable in a chamber sleeve. The bolt handle is, in a form-fitting manner, coupled to a disengagement lever supportable on the chamber sleeve and upon its actuation, causes an axial motion of the axle. The control sleeve receives an axially slidable intermediate piece which surrounds the axle and is operatively coupled at its frontal side with the firing pin and at its rearward side with a striker which arms a firing spring. In the armed state of the firing spring the striker may be locked to the chamber sleeve, via a locking arrangement, by an arming member actuated by the disengagement lever.

  • Patent number: 5722164
    Abstract: The gearing component, in this case a synchronizer ring with synchromesh gearing for automobile gear boxes, is manufactured by cutting it out of a strip of material with a precision cutting machine, at the same time forming gearing out of radial and at least nearly cuboid projections to be stamped into teeth which have a given ratio of tooth height to minimum tooth width. The excess material or flash formed during the stamping operation is removed with a punching tool. The teeth are deburred in a grinding operation, and the edges are rounded off to a certain extent at least. This method not only permits the extremely economical manufacture of such gearing components; a previously unobtainable precision of tooth shape and hardness is also made possible.
