  • This invention relates'to firearms of the selfloading, recoil-operated type wherein the barrel and breech block are locked together by a locking block with which is associated an inertia member adapted, during recoil movement of the barrel extension, to unlock the locking block from the barrel, and the invention has particular reference to the means or arrangement for operating the locking block.
  • the aim of the invention is to provide an improved arrangement for operating the locking block which will permit reduction in weight of the inertia member, thus lightening the gun; which eliminates certain Vparts heretofore used, thus effecting economy in manufacture andassembly, and which will result in a more positive action.
  • Figure 1 is a sectional view taken generally longitudinally and vertically through the rearm with the parts illustrated in nring position;
  • Fig. 2 is a similar view but showing the'parts in position at which the locking :block is about to be disengaged from the barrel extension during recoil of the latter;
  • Fig. 3 is a similar View showing the position which the parts have during forward movement of the ibreech block.
  • the rearm is"shown as" having a frame or receiver I and abarrel II.
  • the barrel has a barrel extension I2 mounted for reciprocating movement within the receiver.
  • a cylindrical magazine I4 from therear end of which the Vshells are transferred, as by means of acarrierinot shown), to the chamber offthe barrel extension.
  • Yrissrociated with the barrel aresuitable ngres ,for reiarding the recoil mevneei f 2 the barrel and then restoring the lbarrel to its firing position upon ring the firearm.
  • This means may conveniently take the form of a recoil spring I5, only a portion of which is shown in the present instance as encircling the magazine.
  • a tube I6 within which is mounted an inertia member I'l. Behind the inertia member is an action spring I8.
  • breech block I9 which carries the firing pin Z.
  • the receiver is provided in its side walls with longitudinally extending grooves 2l for guiding the breech block in its reciprocating movements.
  • locking block ⁇ 22 Carried by the breech block is locking block ⁇ 22 having a rearwardly facing locking shoulder 23.
  • the barrel extension I2 has anopening in its upperwall provided at its rear end with a foiwardly facing shoulder 24 with which the shoulder on the locking iblock is adapted to engage, as shown in Fie. 1'.
  • the locking block is pivoted at its upper rear corner to the 'breech block for swinging movement in any suitable manner, as by means of arcuate lugs 25 vextending from the opposite sides of the locking block and, engaging in arcuate grooves 26 in side walls of the breech block.
  • the locking block swings relative to the breech block about a centeror point indicated by the letter a.
  • the locking block is slotted on its u nder side so as to accommodate the firing pin 20, the spring 21 thereabout, and the forward end of a vlink 35 which constitutes the connection between the locking block andthe inertia memlber.
  • the rear end of the link 35 is pivotally connected to the forward end of the inertia member or guide piece I1 by means of'a parti-cylindrical head 36 engaging in a similarly shaped transverse groove in the forward end of the inertia member.
  • the link is pivoted Ibetween its ends to the rear lower corner of the locking block, as by means of a pin 31.
  • the link, forwardly of this pin, ⁇ has an'a'rm or finger 33.
  • the breech block has, on the rear face'of its forward wall, an upwardly and rearwardly inclined cam surface'39 with which the forward end of the nger 38 is adapted t'o cooperate upon recoil of the barrel, as hereinafter explained more in detail.
  • This face of the'breech block further has a rearwardly facing abutment 48 leading vertically from the upper -end of the cam surface 33, and the forward end of the finger 38 cooperates with this abutment during'the forward movement of the breech block, as will be later explained.
  • the parts described are normally in the firing position shown in Fig. l.
  • the action spring I8 through its forward pressure on the inertia member Il, forces the inertia member, the link 35, and, through the locking block 22, the breech block i9 together so that these parts act as an integral mass to close the breech and maintain the firearm in locked position when the same is fired.
  • the pivot pin 3l is slightly forward of the pivot point a of the locking block.
  • the pivot pin 3l is slightly behind the vertical plane which includes the pivot point a of the locking block, and the engagement of the nger against the abutment prevents the action spring from swinging the locking block upwardly and forwardly. Also, during such movement, the ringer is prevented from moving up against the ring pin spring 2. Actually, the locking block is held downwardly in such position that it might have a slight wiping action against the rear end of the extension. As the breech block moves to its full closed position, the forward end of the link will swing downwardly to the position shown in Fig. 1.
