Definitions

  • This invention relates to bolt action rifles, and in particular to an inactivating selector arrangement for selectively restraining movement of the sear, trigger ot cocking piece or all three.
  • the major components of a conventional bolt action firearm comprise the barrel, a receiver secured to the rear of the barrel, a cylindrical breech bolt mounted in the receiver in axial alignment with the barrel, a firing mechanism including the trigger mounted on the receiver below the bolt, and the stock.
  • the cylindrical breech bolt is rotatable about its longitudinal axis from its locked firing position to its unlocked extracting and loading position, the bolt being longitudinally slidable within the receiver when it is in its unlocked position.
  • a spring powered cocking piece Associated with the breech bolt is a spring powered cocking piece which is held by a sear in the ready-to-fire position. Operation of the trigger moves the sear to release the cocking piece.
  • a bolt action firearm having a barrel, a receiver, a bolt sleeve, a cocking piece, a bolt handle, a trigger and a sear
  • the improvement comprising a multi-positional selector-operated arrangement capable of restraining movement of the trigger and associated sear in a first position and restraining movement of trigger, sear and bolt handle in a second position, said arrangement comprising: trigger and sear blocking means for preventing rotation of the trigger in a direction to release the sear a rotatable selector means positioned in the receiver for rotating about a vertical axis which selector means is rotatable to selected positions, and said selector means having a body portion and a hand-engageable projection portion, actuation means for actuating said trigger and sear blocking means when said selector is turned to a first position and deactuating the trigger blocking means when the selector is turned to a second position, a notch in the cocking piece, a recess in the bolt
  • the present invention comprises a selector arrangement for restraining movement of the trigger or bolt handle or both.
  • the arrangement includes a rotatable selector carrying in fixed relation a selector body portion and a selector handle projection, a trigger and sear blocker associated with the selector body portion, and a bolt handle plunger movable by the selector projection whereby rotatable movement of the selector to first position causes trigger and sear blocker to block movement of the trigger and sear and movement of the selector to a second position causes the selector to continue to hold the trigger and sear in its blocking mode while the selector in addition moves a bolt plunger to restrain movement of the bolt handle.
  • the selector arrangement is passive.
  • selector projection is moved to a position in a recess in the cocking piece as the selector is placed in the second position. In this position, the selector projection will prevent any substantial forward movement of the cocking piece.
  • rifle 10 includes barrel 11, a receiver 12 secured to the rear of the barrel, a cylindrical breech bolt assembly 13 mounted in receiver 12 to the rear of and in axial alignment with barrel 11, a bolt handle 14 secured to the rearward end of the bolt assembly 13, a bolt head sleeve 16, a cocking piece 17, a receiver tang 18 and a stock 21.
  • Rifle 10 also includes trigger 22, trigger guard 23, and a rotatable inactivating selector unit 26.
  • Unit 26 is mounted in the receiver and rotates about a vertical axis.
  • trigger 22 is pivoted about trigger pivot 28 with upper trigger arm 29 engaged in sear notch 31 of. sear 32.
  • Sear 32 is mounted about pivot 33 and spring 36 is interposed between trigger 22 and sear 32.
  • the pulling of trigger 22 to rotate it clockwise about pivot 28 causes trigger arm 29 to move out of sear notch 31 permitting sear 32 to rotate clockwise about pivot 33 thus releasing cocking piece 17.
  • Cocking piece 17 then moves forward under the force of a spring (not shown) to strike the rim of the cartridge (not shown) to fire the rifle.
  • selector unit 26 is rotatably mounted to be turned to and held in three discrete positions determined by detent 37 (see Fig. 7) located on one (1) of the three (3) detent recesses 38, 39 and 40 (Figs. 4-7).
  • Selector unit 26 includes cylindrical body 43 carrying detent 37 in its lower portion (Fig. 7) and two slotted areas 44, 45 in the central part of body 43 define respectively first selector cam surface 46 and second selector cam surface 47.
  • Selector unit 26 also includes a thumb piece 41.
  • Slot area 44 has a thickness greater than cam follower 54 to accommodate follower 54 therein (Fig. 4).
  • Slot area 45 is less thick than slot area 44 so that in the Fig. 6 position cam follower 54 cannot enter slot area 45 but instead rides on cylindrical surface 50 of selector body 43.
  • cam follower 54 housed between frame elements 55 has a thickness greater than slot area 45.
  • cam follower 56 with less thickness than follower 54 is accommodated in slot area 45 throughout the rotational operation of selector unit 26.
  • Trigger control lever 51 is pivotable about pivot 53. On one end lever 51 carries upper cam follower 54 and lower cam follower 56 while on the opposite end trigger blocking finger 57 is located. Lever 51 is urged away from trigger 29 by spring 59.
  • cocking piece 17 has a blocking notch 60 in it for receiving offset thumb piece 41 when selector unit 26 is rotated to the position shown in Figs. 6 and 8.
  • blocking plunger 52 is urged by selector 26 into bolt handle recess 61 to block movement of the bolt handle 14.
  • selector 26 spring 64 withdraws plunger 52 freeing handle 14.
  • selector unit 26 engages and moves trigger control lever 51 to block the trigger and it in turn the sear (see Figs. 4-6).
  • Unit 26 also serves to restrict movement of cocking piece 17 (see Figs. 2 and 8) and actuates blocking plunger 52 to block movement of bolt handle 14 (Fig. 8).
  • selector unit 26 is turned through thumb piece 41 to a passive or neutral position causing detent 37 to snap into a detent recess 38 which places cylindrical body 43 which cam surfaces 46 and 47 in such position that finger 57 of lever 51 does not block trigger 29 (see Fig. 4).
  • the firearm can be fired in this selector mode.
  • the selector unit 26 is moved to inactivating position number one where detent 37 is moved into recess 39 causing surface 46 to move cam follower 54 of lever 51 placing lever finger 57 against trigger arm 29 (see Fig. 5).
  • trigger arm 29 is inactivated by being restrained from rotating clockwise about pivot 28 (as shown in Fig. 3).
  • the trigger 22 cannot rotate and the sear cannot drop to fire the rifle.
  • lever 51 and its finger 57 may be designed to block rotational movement of sear 32.
  • selector unit 26 is movable to inactivating position number two during which movement cylindical surface 5Q moves cam follower 54 to retain lever 51 in its trigger- sear-restraining position.
  • thumb piece 41 As thumb piece 41 is moved to bring selector unit 26 to this third position thumb piece 41 bears against bevelled surface 63 causing blocking plunger 52 to move to the right into recess 61 to block rotational movement of handle 14.
  • Spring 64 is compressed during this movement.
  • thumb piece 41 is in blocking notch 60 of pin striker 17 (cocking piece) to limit forward travel of striker 17 (see Figs. 6 and 8).
  • slot area 45, cam surface 47 and cam follower 56 operate to move lever 51 to the passive or neutral position of Fig. 4 while slot area 44, cam surface 46, cylindrical surface 50 and cam follower 54 operate to move lever 51 into its blocking position and hold it there when selector 26 is in positions number one and two as described above.
  • selector unit 26a (like selector 26) is rotatably mounted to be turned to and held in three discrete positions determined by detent 70 mounted in a detent hole 71 in receiver 12.
  • Detent spring 72 urges detent 70 into recesses 73, 74 and 75 in selector unit 26a.
  • Selector unit 26a includes thumb piece 77, cylindrical body portion 78 including configured foot portion 79. Foot portion 79 carries notch 81 providing a configuration for engagement and disengagement with the trigger which will be explained.
  • Trigger 82 pivotable about pivot axis 83, includes finger piece 84, sear-engaging upper trigger arm 86 and trigger extension 87 including extension block 88. Also shown in Figs. 16 and 18 are trigger side pieces 89, 91, sear 92, sear spring 93, sear pin 94, selector cover plate 95, and rifle sight 96.
  • Figs. 12, 13 and 14 it is seen that when selector unit 26a is in position A (Figs. 12 and 14), configured foot portion 79 of selector 26a is positioned to accommodate extension block 88 thus permitting clockwise pivoting of trigger 82, the release of sear 92 and firing of the rifle (Fig. 12).
  • Trigger 82 cannot in these positions be rotated clockwise to release sear 92 to fire the rifle.
