Definitions

  • the invention relates to a rebound lock for small arms, and its object is to afford the possibility of a deeper bend in the cocking piece, thus ensuring absolute safety of the lock without prejudice to the gentleness of the ull off. 'In addition, the intention is to construct the lock so that it may be stripped without the aid of auxiliary tools.
  • a small arm lock is already known in which 1) a pawl actingas a power transmission device transmit-s to the sear a part only of the force of the mainspring acting directly upon it.
  • the mainspring is secured at itsapex by a pivot in the lock 35 plate, so that it cannot transmit its full striking force to the cocking piece.
  • considerable cocking is required, which slows down the firing considerably.
  • the pawl acting as a power transmission de- 23 vice is mounted between the pivot of the cocking piece and the pivot of the sear, which gives a very long lever arm to the nose end of the sear, and consequently results in a very harsh and stiff pull off. The safety of the lock is rendered questionable by this device.
  • a rebound lock with a very gentle pull on is obtained by the use of the known transmission device in the form of a bridge, the bridge being placed loosely, with its forked end embracing the cocking piece, on a retaining pin in the lock plate, the said bridge by co-operating with the mainspring, which is placed 5 with its apex resting freely against a stop pin on the lock plate, holding together all the movable parts of the lock, the said parts being secured to the lock plate by the chain which is passed through a slot in the retaining pin.
  • the sear is preferably guided in a groove in the lever end of the bridge.
  • the bridge may at the same time hold the end of a leaf spring of an indicating device, while the other end of the bent leaf spring, with the pin secured'thereto, is actuated by the cam on the underneath part of the'cocking piece, so that when the pin projects laterally from the lock plate, it indicates that the lock is in the cocked position.
  • Figure 1 is a side elevation of the uncooked Figure 2 is a view of the same'fromabove.
  • 1 liigure 3 is a side elevation of the cocked Figure 4 is aside elevation of the-lock plate with the parts riveted thereto.
  • Figure 5 isa view of the same from-above.
  • Figure 6 is the bridge in three views.
  • Figure 7 is the indicating pin withthe leaf springin two views.
  • Figure 8 is the mainspring viewed from above, and a side elevation of the upper limb of the m'ainspring.
  • Figure 9 is the sear in'two views.
  • Figure 10 is the cooking piece in two views.
  • Figure 11 is the chain in two views.
  • Figure 12- is the lock in perspective.
  • the sear ( Figure 9) is made in the form of a double armed lever, mounted rotatable about the pin 0, and is held by the side walls m of the groove a in the free end of the bridge.
  • the end 0 of the shorter lever arm p may engage in a bent g of the cooking piece.
  • One end of a leaf spring 1" is pressed against the lock plate by the bridge.
  • a pin 8 is fixed to the other ent of the leaf spring.
  • Leaf spring and pin together act as an indicating device.
  • the pin 8 is pressed by a cam t on the under portion of the cocking piece through a hole in the lock plate, and thus indicates in a manner visible from the outside the cocked position of the lock.
  • a rebound lock for small arms in which a power transmission device, for example a bridge, transmits to the sear a part only of the force of the mainspring acting directly on the said device, characterized in that the transmission device constructed in the form of a bridge, is placed loosely with its forked end embracing the cooking piece on a retaining pin on the lock plate and with the cooperation of the mainspring, one forked limb end of which rests hingedly in the known manner on the chain pin of the chain, while the second similarly forked limb end of the said mainspring rests hingedly in a depression of the bridge, holds all the movable parts of the lock together, the said parts bein secured to the lock plate by means of the chain passed through a slot in the retaining pm.
  • a power transmission device for example a bridge
