Definitions

  • This invention relates to a breech bolt. mechanism for sporting guns.
  • the invention is characterized by the arrangement of a sleeve onthe shaft of the locking bolt actuat- 5 ing key the said sleeve being acted upon by the locking spring whichis preferably made in the form of a spiral spring.
  • the said key shaft and sleeve are of such construction that their coupling may'not be effected otherwise 1 than by mounting them into the breechbody.
  • the said spiral spring acting upon the saidsleeveon' the key shaft is so arranged that while one end thereof is act ing upon the sleeve the other end is supported by a spring casing which may be easily in-' serted into and extractedfroni the gun.
  • a spring casing which may be easily in-' serted into and extractedfroni the gun.
  • Figs. 2 and 3 show the two portions'of the key shaft, each for itself.
  • I i I v 7 Figs. 4 and 5 are different elevations of the key.
  • Fin shows the keymounted in the breech body together with its actuating spring and the casing of the latter, in a horizontal seci 130 tional view.
  • the key 1 is'provided'with the conventional square hole-2 (Fig. 4-) into which the squared
  • the upper bolt 8 is opera ated by'the notch'9of thekey 1, in which 7 engages the lug 10, of the'said bolt 8 :(Figs. 1. and Mounted onthe shaft 3 there is a sleeve 11,the nose1'2 of which fits into the notch 14 of the key 1, whereby a connection betweenthe sleeve and the key is established.
  • the spring 16 actsupon the shoulder 18 of the sleeve 11 through'the intermediationof the pressure piece 17 andtends to rotate the same in the-direction of'the arrow shown in Fig. 6. Since the sleeve 11 is coupled to the key 1 and the latter is connected to the shaft 3, the spring 16 will swing the keyl as well as the "shaft 3 in the same direction. By the swinging of the key 1 towardsthe right, the two bolts 7' and 8 are withdrawn in a well known manner, the spring lfibeing atthe same time tensioned.
