Definitions

  • the object of the invention is to obviate these disadvantages, this being achieved by constructing the cylinder spindle as a component part secured in its functional position by two cooperating members one of which, by being adjusted into the uncoupling position, causes the cylinder spindle to be initially pushed out of the weapon by the second member for the purpose of facilitating the removal of the cylinder spindle.
  • the proposed construction solves the problem of securing the cylinder spindle in such manner that the two conditions mentioned, namely good security and easy manipulation when dismantling the weapon, are satisfactorily fulfilled. At the same time, a simple mechanism and a smooth unbroken surface of the weapon are retained, as are required in this case in view of easy carrying, use and maintenance of the weapon.
  • Figures 1 and 2 are partial longitudinal sections of the weapon with the cylinder spindle in the secured and released position;
  • Figure 3 is a partially sectioned side elevation, the section being taken in the plane of the line 3-3 of Figure 1;
  • Figure 4 is also a partially sectioned side elevation, the section being taken in the plane of the line 4-4 of Figure 2.
  • the cylinder spindle 1 carrying the cartridge cylinder 2 is mounted in the usual manner with its two ends in the frame 3 of the weapon, to which is connected the barrel 4, and can be removed from the weapon by sliding it longitudinally towards the mouth of the barrel.
  • the cylinder spindle 1 is constructed as a component part secured in its functional position by two cooperating members. Said members are at the same time so conall) structed and arranged that one of said members, by its adjustment into the uncoupling position, causes the cylinder spindle 1 to be initially pushed out of the weapon by the second member for the purpose of facilitating the removal of the cylinder spindle.
  • the first of said securing members is formed by a segment head 5 of the front end of the cylinder spindle 1, which projects into a lateral recess 6 of the barrel 4 ( Figure 2), by which the cylinder spindle is secured against axial displacement and out of which the segment head 5 can be pushed by swinging it out to the side ( Figure 4).
  • the recess 6 is so arranged and constructed that the head 5 of the cylinder spindle 1 in both its positions ( Figures 3 and 4) is practically completely concealed beneath the barrel 4 and projects beyond the lateral outlines of the weapon frame 3 only by part of its rounded side wall, which is provided with a serrated manipulating surface.
  • the cylinder spindle 1 can therefore be turned and be withdrawn from the frame 3 by means of the head 5. Since the head 5 of the spindle 1 must be concealed at a place where manipulation is very inaccessible, the weapon is provided with a further member which facilitates its removal.
  • Said member is formed by a spring loaded pin 7, which is slidably mounted in the frame 3, for example by means of a limiting pin, and is provided with a profiled head, in the present case a conical head as shown in Figures 1 and 2.
  • the head of the pin 7 engages in a corresponding recess 8 in the rear of the segment head 5, which recess is so arranged that it 10- cates the secured position of the head 5 of the cylinder spindle 1 ( Figures 1 and 2).
  • the entire securing mechanism is concealed in the weapon frame and therefore in no way disturbs the smooth lines nor simplicity of the weapon. At the same time, dismantling is facilitated in spite of the relatively poor accessibility of the head 5, although only a small part of the latter projects outwards for manipulation,
  • a cylinder revolver the combination of a frame, a barrel extending forwardly from said frame, a cartridge cylinder fitting in said frame, a spindle received in said frame to rotatably support said cylinder within the latter, said spindle being removable axially forward from said frame below said barrel, a segment head on the forward end of said spindle, said barrel having a laterally opening recess in which said segment head engages to resist axial removal of said spindle, said head being movable laterally out of said recess in response to swinging of the head and spindle about the axis of the latter, a spring loaded pin slidably carried in said frame parallel to said spindle and yieldably urged out of the frame to bear against the back face of said segment head, and said back face of the segment head having a detent recess therein positioned to receive said pin when said head engages in said laterally opening recess of the barrel so that said pin normally yieldably resists swinging of said segment head out of said recess of
