Abstract
A camblock assembly with a camblock and a guide rod is employed in a firearm having a frame constructed of synthetic polymer material. The camblock has a front flange with flange surfaces that engage corresponding bearing surfaces of the frame to distribute forces and energy to the frame during recoil of the firearm. A shelf member is positioned at a front end of the camblock and a coiled flat wire buffer spring is positioned about the guide rod to resist movement of a reciprocating slide. A detent mechanism positioned within the camblock contacts a surface of a slide stop pin to hold the slide stop latch in place. The interior of the slide stop latch contains an elongated wire having an end that engages the frame such that the slide stop latch is biased in a down position.

As seen inFIG. 5 , duringrecoil front shelf 48 ofcamblock 38 directly contacts curvedback end 79 oflower portion 26 ofslide 12 such thatfront face 78 ofshelf 48 acts as a significant frame stop surface. - As seen in
FIGS. 4 and 5 , coiled flatwire buffer spring 42 aboutguide rod 22 is positioned inside ofrecoil spring 41.Buffer spring 42 is sprung assembled onguide rod 22 such thatfront end 80 ofbuffer spring 42 faces guide rod bore 31 ofslide 12 andback end 81 ofbuffer spring 42 facesfront flange 45 at the front portion ofcamblock 38. (FIG. 4 ).Buffer spring 42 is preferably constructed of spring tempered steel material. As seen inFIG. 5 , whentrigger 15 is pulled and the firearm fires, recoil forces cause theslide 12 to move rearwardly towardcamblock 38.Recoil spring 41 compresses and is pushed by reciprocatingslide 12 back towardsfront flange 45. In addition, as thelower front portion 26 ofslide 12 begins to approach thecamblock 38, a surroundingarea 82 about theinterior end 33 of guide rod bore 31 engagesfront end 80 of coiled flatwire buffer spring 42. Back end 81 ofbuffer spring 42 engagesfront portion 40 ofcamblock 38 and makes contact with thefront flange 45 proximate the connection point withguide rod 22 such thatbuffer spring 42 compresses and resists the backward movement of thereciprocating slide 12. - Referring to
FIG. 4 ,chamber block 23 which receives cartridge C as loaded and from which cartridge case is extracted after firing (FIG. 5 ), hasfront camming projection 35 andrear camming projection 36 extending from a lower region ofchamber block 23. Whenpistol 10 is in the locked up fire position,FIG. 4 , a mountingsurface 84 positioned slightly ahead offront camming projection 35 of thechamber block 23 rests atop of thetop flange surface 66 f offront flange 45. Flatbottom surface 85 ofrear camming projection 36 rests atop a correspondingflat camming surface 86 ofcamblock 38. Whentrigger 15 is pulled andpistol 10 fires (FIG. 5 ), recoil forces causeslide 12 to move rearwardly againstrecoil spring 41 untilfront camming projection 35 of chamber block abruptlycontacts camming projection 50 ofcamblock 38 and flatbottom surface 85 ofrear camming projection 36 engages arear camming surface 87 of thecamblock 38. Upon firing,barrel assembly 30 moves back and down andchamber block 23 disengages fromslide 12. - The
barrel assembly 30 is accelerated to a high speed by movement of theslide 12 in which the acceleration and rotational movement back and down continue until the front and rearend camming portions barrel 20 are abruptly stopped by engagement with thecamblock 38. Additionally, slide 12 quickly accelerates rearwardly upon firing until thelower front portion 26 ofslide 12 contacts thefront shelf 48 ofcamblock 38 thereby stopping further backward movement of the slide.Buffer spring 42 is positioned aboutguide rod 22 such that itsfront end 80 engages the surrounding area of theinterior end 33 of guide rod bore 31 at the front of theslide 12. Theback end 81 ofbuffer spring 42 abuts against thefront flange 45 thereby enablingbuffer spring 42 to compress and resist the rearward movement of theslide 12. Forces and energy from stopping rapid movement of theslide 12 and the stopping of thebarrel assembly 30 are transferred to camblock 38, and in turn to non-metallicsynthetic polymer frame 11 by the various camblock surfaces including the significant number of flange surfaces 66 a-66 f which bear against many bearingsurfaces 28, 68 a-68 f of the frame. Theslide 12 andbarrel assembly 30 forces are also transferred into theslide stop pin 54 and are absorbed into theframe 11 by thepin 54 which passes through frame holes 55 a, 55 b (FIG. 9 ). - Referring now to
FIGS. 2 and 6 -8, positioned withincamblock 38 isdetent mechanism 53 which engages asurface 88 ofslide stop pin 54 to hold the slide stop pin in place upon insertion of theslide stop latch 13 to theframe 11 offirearm 10.Detent mechanism 53 includeswire form 56 which extends across atop portion 89 oftransverse opening 52 ofcamblock 38.Slide stop pin 54 is inserted through slide stop opening 55 a, 55 b offrame 11 as well as thetransverse opening 52 ofcamblock 38. Wire form 56 (FIG. 6 ) extends acrosstop portion 89 oftransverse opening 52 at thedistal side 90 ofcamblock 38 which is the side opposite to where theslide stop pin 54 is inserted into thecamblock 38.Slide stop pin 54 has acircumferential groove 58 formed aboutpin surface 88 whereby upon insertion of theslide stop pin 54 throughtransverse opening 52 of thecamblock 38, thedetent mechanism 53 spring biases down into engagement with thegroove 58 for securement of the slide stop pin within the camblock. As seen inFIG. 6 ,wire form 56 includes anintermediate portion 91 positioned between two loopedportions camblock 38 has a pair of retainment bores 57 a, 57 b formed on opposite sides of thetransverse opening 52 and the retainment bores house loopedportions wire form 56. Thecamblock 38 contains achannel 93 extending between the retainment bores 57 a, 57 b for receipt of theintermediate portion 91 of thewire form 56 which engagesgroove 58 of theslide stop pin 54. - Positioned within an
interior portion 61 ofslide stop latch 13 is elongatedwire 60, as seen inFIG. 6 . The elongated wire has two ends 62, 65 with oneend 62 bent outwards in a direction that is in alignment withslide stop pin 54 and is positioned for receipt in acorresponding bore 63 of frame 11 (seeFIG. 2 ). Theother end 65 of theelongated wire 60 is held within theslide stop latch 13. (SeeFIGS. 6-8 ). Theinterior portion 61 of theslide stop latch 13 has a taperedchannel 94 which houses elongatedwire 60.Tapered channel 94 has awide portion 95proximate end 62 ofelongated wire 60 and anarrow portion 96 proximate theother end 65 which is fixedly held within theinterior portion 61 ofslide stop latch 13. (FIG. 6 ). Theelongated wire 60 rides along atop edge 97 of the taperedchannel 94 thereby spring biasing theslide stop latch 13 to be held in a down position when the slide stop latch is inserted into theframe 11. Theelongated wire 60 is able to be pivoted from the held position where it engages thetop edge 97 of the taperedchannel 94 to a pivoted position whereby the elongated wire contacts abottom edge 98 of the taperedchannel 94 upon the user applying an upward force to theslide stop latch 13 when the latch is inserted intoframe 11 andpistol 10 is assembled. - As noted above, the
elongated wire 60, positioned within taperedchannel 94, spring biases theslide stop latch 13 in a down position during firing operation of thepistol 10. However, as seen inFIG. 7 , whenmagazine 17 is empty,magazine follower 64contacts extension member 99 ofslide stop latch 13 and applies an upward force to the slide stop latch such that thelatch 13 pivots in an upward direction whereby theelongated wire 60 is moved down and engages thebottom edge 98 of the taperedchannel 94. It will be understood that the interior ofmagazine 17 contains one or more springs (not shown) which apply an upward force onmagazine follower 64 to pushextension member 99 ofslide stop latch 13 in an upward direction. When pushed in the upward direction,slide engagement block 100 of theextension member 99 is moved upward and is enabled to be locked into position with mating notch 101 (FIG. 2 ) of thereciprocating slide 12 to hold the slide in the rearward position whenmagazine 17 is empty of cartridges. - Although certain embodiments have been depicted and described in detail herein, it will be apparent to those skilled in the relevant art that various modifications, additions, substitutions and the like can be made without departing from the spirit of the invention and these are therefore considered to be within the scope of the invention. While a detailed description of certain embodiments has been provided, it should be appreciated that many variations can be made thereto without departing from the scope of the appended claims.
