Definitions

  • This invention relates to a trigger and safety mechanism for sporting guns.
  • One ob ect of the invention is to provide a sporting gun the cocking members of which;
  • Another object of the invention is to provide a cocking mechanism for sporting guns in which the member releasing theautomatic 1o cartridge ejector is coupled with th ecocking member, by means of a screwthreadj this rendering the effective length of said cocking element as. well as that of the releasing element for the automatic cartridge ejector adj ustable at will.
  • o A i A further obj ect of the invention is to provide a cocking mechanism for sporting guns in which the cocking elements are in perma nent contact with the hammers under the positive action of a spring.
  • a still further objectof the invention is to provide a sporting gun in whichthehammers may act as backthrow hammers forwhichpurpose the cocking mechanism-according to the present invention is so devis'dthat the mers pushin'g the latter backwards'so that the firing pins of the hammers are forced away from the chambers.
  • A- still further object of theinvention is to provide a trigger and safety mechanism for sporting guns in which not only the triggers mechanism by means of hooks provided on the side faces of the hammers,- the said hooks cooperating with counterhooks governed by the safety bar; the hammers being thus secured m their cocked position.
  • the safetycounterhooks the safety bards provided with suitable oblique surfaces.
  • a still further object of the invention is to provide a sporting gun in which the safety or released condition of the gun will a ways be completely established as soon asthfe operati'on of the safety device is initated by hand so that the completion of the operation of the safetydevice does not depend on the gunman.
  • the safety bar is con structed in such a manneras to be influenced by a spring controlled lug having a wedge shapeden'd so that if the actuating of the" safetymechanism is initiated by hand one of the conditions above mentioned will be automatically established.
  • trigg'e'rand safety mechanism attaining tothe' invention is shown byway of example.
  • Fig. 1. is a vertical section through the breach body of the gun the hammers being uncooked.
  • t I it a Fig. 2 is a similar section with the-hammers cocked, hammers and triggers secured.
  • Fig. 3 is a top view of the breech body showing thekey effecting the opening of the Y gun, the said key having a nose operating. the safety bar which is shown in dotted lines.
  • Fig. 4' is a horizontal sectional view of the secured by the safety device thesa' fety bar being shown with its forked front end, the arrangement 'of'the signal pins beingalso, shown in this figure.
  • Fig. ,5 is a partial front-view of the breech bodyand shows the front end of thecocki'ng members together with the member effecting the release of the automatic cartridge ejector;
  • Fig. 6 is a cross sectionalview of the breech body taken on line of Fig.- 2.
  • N Fig. 7 is a longitudinal sectional vieW'of the breechbody taken on line VIIV'II of Fig. 1.
  • the hammers 3 are pivotally arranged on the axle 2 inthe' breech body 1 and are actuated by the pin which is under the action of the firing spring 4..
  • the nose portion'6 of "the hammers 3 is'influenced by the cock 'ing rods 7 pressed against the nose portion 6 of the cocks by the spiral springs 8. 'The' stroke of the cocking rods 7 is limited by the screws 9 (Figs. 1 and 6)
  • the release members 10 To the'front end of the cocking rods 7 are secured the release members 10 which are screwed on the cocking rods 7 and are of such construction that their shoulder 11 cooperates with the cocking le- 7 vers 13 pivotally mounted round the pin 12.
  • the release members 10 have a tooth 38 arranged atLtheir front .endfand'adapted to release some known type ofautomatic cartridge If the cocking rods 7 and therewith ejector.
  • the release members 10 maybe screwed inwards 0r outwards on the cocking rods within the limits of the screw thread provided thereon'whereby on the one hand the length of the teeth 38 of the release members and on the other hand that of the cocking rods may be adjusted at will. This adjustment is of importance for the reasonv that thereby the cocking of the'hammers as well as the automatic ejection of the cartridge may be influenced.
  • the key is also provided with a proj ecticn 17 (Fig. 3) which at the turning of the key works the safety bar 18 and positively pushes the same into its safety position.
  • Th'e safety lever '19 the head portion 20 of which is connected to the safety bar 18, is made in the form of a two armed lever the forked arm 32'of which secures the triggers 30 and 31 in a knownmanner.
  • the safety lever 19 is also provided with a wedge shaped prolongation 21 subject to the action of a spring actuated wedge This' mechanism will move the whole of the safety device as soon as the shaped "pin 23.
  • Thesafety-bar 18 has a fork shaped forward end: the two branches 24 (Fig. 4)' of which govern thefhooks 26 and 27 subject to the action of'the common spring 25 in such a 'manner that the said hooks are interconnected in thesafety position of the gun with the hooks 28 and 29 of the hammers 3 thelatter beingthereby secured in their safety position.
  • the signal pins 33 and 34am actuated by the springs 35 ina well known man-- V ner-and aregovernedby theoblique surfaces 36and 37'0f the hammers 3.
  • Atrigger and safety mechanism comprising a cocking member provided with an extension for. releasing the, automatic car tridge ejector therelease member for the cartridge ejector being connected to the cocking memberby' a screw thread in such a manner that thelength of the release member and of the cocking'member should be adjustable.
  • a trigger and safety mechanism for sporting guns comprising a hammer, a firing spring and a cocking rod, means for limiting the stroke ofthe'firing spring in such amanner that it'may not influence the hammer in erned by the safety bar by means of oblique surfacesthereof.
  • a trigger and safety mechanism according to claim 1 in which the hammers are provided with hooks cooperating with counterhooks movable in a direction at right angles to the longitudinal axis of the gun by the safety bar, the counterhooks and the spring actuating the same being arranged in the same aperture in which the signal pins actuated by the hammer are provided.
