Definitions

  • Hitherto known types of breech loading guns have proved to possess important defects, one of which is that the aXis about which the barrel is rotated on breaking the gun is disposed below the said barrel, resulting in uneven distribution of the stress on the breech lock.
  • the barrels are soldered together or are bored from a single piece of material so that the wall thickness of the barrels is not the same around their entire circumferences. Uniform vibration of the barrels is consequently impossible and the uniformity of the shots is thus impaired.
  • the arrangement of the breech lock is also unsatisfactory, since on account of its construction, it can be made by the most skilled workmen only and nevertheless, soon begins to display weakness in that its parts no longer fit together with the necessary precision.
  • the obj ect of the present invention is to obviate these defects in guns of the type set forth.
  • FIG. 1 and 2 are longitudinal sections, perpendicular to each other', of a part of the gun
  • Fig. 3 is a plan of the breech lock
  • Figs. 4 and 5 illustrate in longitudinal and cross sections respectively the arrangement of the sight bar
  • Figs. 6, 7, 8 and 8a are cross sections on the lines mit', yy, zz and mi in Fig. 1 respectively.
  • Figs. 9, 10, 11 and 12 show the hinge member in side elevation, plan, end view and cross section on the line t in Fig. 9, respectively.
  • Figs. 13, 14, 15 and 16 are a side elevation plan and end views respectively ofthe mounting with its trunnions, for the barrels and Figs. 17, 18, 19,20 and21 illustrate the lockvbody in side elevation, plan, end views and section ⁇ onthe line 'Lm of Fig. 17 respectively.
  • the embodiment of the invention illustrated is a double-barrelled gun in which thc rear ends of the barrels 1 are fitted into bores in a mounting block 2.
  • the said mounting block has side cheeks 3 to which the wood sheathing 5 is secured by catches and an adjustable bolt 4 and isalso provided with a horizontal rib 6 which maintains the barrels 1 at the desired distance from each other.
  • Each of the two side faces of the mounting block is provided with a trunnion, the aXis of which intersects the dividing line between the barrels at right angles.
  • the said trunnions serve for the mounting of the mounting block in thel slots 8 in the side cheeks 9 of the hinge member 10.
  • the barrels 1 are maintained at a definite distance from each other as far as their muzzles and are secured together by front and rear releasable straps 12, 11.
  • the sight bar 13 is mounted loosely on the upper barrel, is provided with recesses 14 in its lower surface, and is prevented from longitudinal movement both by the rim of the strap 11 and by the fact that its reduced ends 15, 16 are inserted in corresponding recesses in the mounting block 2 and the strap 12 (Figs. 4 and 13).
  • the closure of the breeches is eifected by piston like members or bolts 17 which fit in the ends of the bores of the mounting block 2 and are guided in chambers 18 (Fig. 9) in the hinge member 10 in such a manner that, at the eXtreme limit of their movement away from the mounting block, they emerge from the latter and allow the barrels to be dropped.
  • the bolts 17 and the transverse wall 19 between the chambers 18 of the hinge member 10 are bored co-axially to accommodate the locking cylinder 21 which is fitted with a locking lever 2O and is secured to the lower side of the hinge member 10 by means of an eccentric fastening 22 or the like.
  • the bore in each bolt 17 is specially shaped for a purpose which will be explained below, exhibiting a step 23, corresponding to a projection 24 on the locking cylinder, and an inclined surface 25 which abuts, when the bolt is drawn back, on a surface 26 on the locking cylinder. In the locking position the arcuate cylindrical portions 27, 28 of the cylinder bear tightly against corresponding co-aXial surfaces in the bores of the bolts.
  • T he bolts 17 and the locking cylinder 21 are bored co-aXially with the barrels, and the coaxially arranged members 29 and 30 which press resiliently against each other and conjointly form the strikers are disposed and guided in the bores.
  • the object of this arrangement is to obtain firstly aXial striking movement of the strikers and secondly a cer-- tain safety action due to the lfact ⁇ that striking of the members 30 on the members 29 can only occur when they are exactlyl axially aligned, that is, only when the mounting block 2 is locked.
  • the lock is mounted directly on the hinge member 10 and consists of a lock body 31 in whichare guided hammers 32 which strike the striker members 30 through openings 33 in the rear wall of the said hinge member.
  • A. setting or cooking plate 35 under the influence of a spring is mounted on a swallow tailguide 34, (Figs. 19 and 20) on the rear side of the lock body.
  • a spring controlled crank lever 40 which is pivotally mounted on the wood Vsheathed bar 41 in such a manner that, on tilting the barrels, one arm of the lever presses back the rod 38, thus setting the hammers.
  • the trigger rods 43 operated by trigger 'arms 44 on the triggers mounted in the look,
  • the safety action proper of the gun is a direct action on the trigger rods.
  • vthe upper yend of the locking cylinder 21 provided lwith an eccentric recess 45 (Fig, in which lies the endof a spring bolt 46 which is guided in the hinge member 10. 0n opening vthe lock and rotating the locking cylinder the end vwall of the recess 45 presses back the bolt 46 which strikes a slidably mounted bar 47 to which an arm 48 on a stop member 49 is ieXiblv connected.
  • the latter ⁇ is rotatable about the trigger pivot 50 and projects through the rear wall of the lock body ⁇ by means of arms 51 into the paths of the trigger rods.
  • the position Vof the stop memlier 49 is fixed by a detent member 52 which yin order to be able to V53 on the lock body.
  • the trigger guard 55 is secured at its for ward end by the previously-mentioned eccentric fastening or catch 22, that element having a lateral projection which engages a groove in the forward end ofthe guard and also secures the-locking ,cylinder 21 to the lower side of the hinge member 10 with the aid of another eccentric projection. Its rear end is loosely pivoted to the tail 56 of the lock and supports a pin 57 ,which engages ina slide 58 mounted in the .lock tail. In its' assembled position the end of the slide 58 abuts against a plate 59 secured in the stock.
  • the gun is composed of members which can be manufactured by machinery in quantity and without any finishing operations by hand, and, secondly, that it is only necessary to release the two connections 4 and 22 strip the gun in a simple manner.
  • a hinge member secured to the stock of the gun and provided with forwardly-extending cheeks, theV inner faces whereof are slotted; a mounting block pivotally journaled between said cheeks and provided at opposite sides with laterally-projecting trunnions which are journaled in said slots; and awpair of ⁇ fba-rrels having their breech ends iitted in the block, said block having means for maintaining the barrels a predetermined distance from each other.
  • a hinge member secured to the stock of the gun and provided with forwardlyeextending cheeks, the inner faces whereof are slotted; a mounting block pivotallyjournaled between said cheeks and provided at opposite sides with laterallyprojecting trunnions which are journaled .in said slots; a pair of superposed barrels having their breech ends tted in theblock, said barrels being free of contact with each other throughout their entire length; and removable straps for securing the barrels together.
