accorti n-EnUoER AND ACCURACY IMPROVER Richard L. Shockey, El Reno, Okla'. lamination May 1s, 1951, seria1No.227,'o"6s (o1. lifa-1) 3 Claims.
The present invention relates to a recoilreducer and; `accuracy,improver for. automatic weapons and it consists in the combinations, 'constructions and arrangements of parts herein described and claimed.y
Generally the, invention comprises a device wlilchmay be substituted, for example, in the Colt .45 automatic. pistol, forV the conventional recoili spring plug and recoilspring guide containedin such weapons. Its purpose is to improve the. ,ccuracy of such weapons and lto distribute the recoil of 4vthe same when nred in such manner astomakethe gunmore pleasant to fire. Such recoldistribution is also agreat aid in rapid fire sltiooting.V The device for-ces the. barrel, slide and frame of, the conventional' pistolinto their same relative positions each time the slide comes to restin its forward position. It also cornpensates` for wearon the barrel, barrel bushing, slide, and pin construction and the frame. While; accuracy is partly achieved by the reductren orre'coii, it is also accompiishedby having the barrel, slide and frame in the same position each time the weapon is fired. `Due to mass production, these parts nt very loosely and do not always come to rest in the same' positions after each shot. With the present construction the barrel of theweapon is forced to assume its same position with respect to the frame after each shot thus making for a great improvement in the accuracy of the Weapon. A
It is accordingly anobject ofv the invention to provide a recoil mechanism for automatic pistols and the like whichA may be quickly and easily substituted for the conventional recoil spring plug, and recoil spring guide of such weapons.
,Another object of the invention is the'r provision of a device of the character set forth which is'y comparatively simple in construction; easy to manufacture and yet effective and efficient in use.
Another object of the invention is the provision of'a device of the character set forth having means'for maintaining'the'same in constant'relativ'eposition'totheconventional parts of an automatic pistol;
A further object ofthe invention is the provision, in a device ofthe character set forth, of av novelv spring and guide groove therefor forming a part of the invention.
A further object of the invention is the lprovision of novel means f'or the prevention of wear in a spring and barrel forming a part of fthe invention.
Other and further objects of theinvention will become apparent from a reading ofthe followingr specificationtaken in conjunctioniwith the drawings, in which:
Figure' 1 is a side elevational view, partly broken away, oran embodiment' of' theA invention shown in` position in an automatic pistol,
2 Figure 2 is anenlarged fragmentary vertical sectional view, partly in elevation, ofV the: devicey f' Figure 3 is Va fragmentary sectional YView ttaken substantially along lined-3, of E igure 2,
Figure,v 4 is asectional view taken along line -Qof Figure?, Figure 5 is a sectional view taken along line 5 5 Figure-2;.
Figure 6 is a View Similar t0 Fellr but SHOW: ing thel device at the moment o fV its` most rearward movement, i f
Figure '7 is a perspective view of' the forward portion of the device forming fthe present invention, Figure portion of the tion, and Figure 9 is a fragmentary sectional view similar to, Figure 5 but enlarged and illustrating certain details of construction.
Referring more particularly tothe; drawings, there is shown thereinan automatic pistol including a frame Ill, a conventional' barrel Il and a slidel2. In Figure 7` there is generally illustrated' at, i3 a forward assembly whichreplaces in a pistol the conventional recoil spring plug and in QFig ure 8 of the drawings there i's generally illustrated at I4 arearward assembly which replaces in a pistol the conventional recoil spring g1 1 il e kThe forward portionof the slide Il? provided with a dependent portion |2a` which normally houses the forward assembly; 3.A
The forward assembly I3 consists of a hollow longitudinally extendingcylinder i5 provided at its forward end with as olid reduced portion [5 which is adapted to' normallyextend through an opening I1 formed ina bushing I'8" mounted in the forward end of thesiide l2'.4
The rearwardjend is a perspective view ofA rearward device forming the present invenf Glaylir l5, is prOf vided with a squaredilange I9 which bears against the frame' HT ad also k$Ds the frame and slide in close augnmnt; The aange-isis provided with a rounded lower ledge 2li', t`o which` is aix'ed a rearwardly extending lug'- 2 f in' which is mounted a rearwardly and downwardly ci@ tending spring 2 2. repm 2 3' is cent1-any' and longitudinally aiiixedto' the inner face? o 'f the reduced portion I6 within the' cylinder I if and the lower end of the spring 2`2 is upturne`d slightly, as indicated at 24. The lower end of the Spring 22 aafdaldii@ bei received iff longitudinal. groove 25;. f9'rn 1 l T.. of that partl of the frame accornniodati'IigY the rearward assembly Il'.
29 bearing, asainstithe underside Y0i thejblerrel lil'.-
The rearward assembIy I4: comprises a.' cylinder 3 whose outside diameter is such that it may readily be received within the cylinder I5 when the forward assembly is moved rearwardly by the recoil of the pistol. Within the forward end of the cylinder there is afxed a collar 3i having an opening 32 centrally disposed therethrough. The cylinder 30 is provided with an irregularly shaped rear wall 33 provided at its upper end with a rounded groove 34 which is adapted to bear against the underside or the barrel Il and with outwardly extending rounded sides 35.
In either vertical half of the member 33 there isprovided a downwardly and outwardly extending passageway 35 in the upper end of which is mounted a plug 3i and in the lower end of each of which is slidably mounted a pin 33. A compression spring 39 is mounted in each of the passageways 36 and each is adapted to abut against its associated plug and pin 38. A cylindrical plug il is slidably mounted within the cylinder 30 and normally bears against the inner side of the collar 3| being urged into such position by means of a coil spring 4i mounted in the cylinder 3Q and bearing against the member 33 at its rear end and against the plug de at its forward end.
In operation, it will be apparent that when the pistol is red, the slide I2 will move rearwardly with respect to the barrel Ii thereby carrying with it the forward assembly i3 as a result of which the pin 23 will enter the opening 32 as the cylinder 30 passes into the cylinder i5. During this operation the lower end of the spring 22 will slide along the groove 25 and at the same time prevent rotation of the cylinder l5. When the pin 23 comes into contact with the plug 4D it will act to move the same rearwardly against the action of the spring si to thereby absorb and distribute some of the recoil from the ring of the pistol. As the action just described occurs, the spring 2a will bear against the underside of the barrel Il and the roller 2d, if mounted thereon, will prevent wear upon the spring 28 and barrel H. This action of spring 28 acts to maintain the relative parts of the pistol and the recoil mechanism just described at all times in their proper relative positions. WhenV the forward assembly i3 has reached its rearmost point in the recoilaction, the lug 2i will be received in a groove i2 formed in the lower end of the member 33. It will also be noted that the spring pressed action of the pins 3&3 against the inner walls of the body of the pistol will likewise maintain the various parts above described in their proper relative positions.
While but one form of the invention has been shown and described herein, it will be readily apparent to those skilled in the art that many minor modifications may be made without de parting from the spirit of the invention or the scope of the appended claims.
