(Cl. 248-229) This invention re l ates -generallv .-tonight seeing devices-ion fire farms-and in ..particular ;to anattachment for-supporting .a fiashwli'ght on...

the barrel or breechoia gunk An object otthisiinventionis to provide'an improved-hash .light supporting attachment for Another object of thisinventionis to provide -a flash light attachment for agun which is read-' ily adjusted to focus a light pattern i'n a proper relation with the sights on the. gun barrel.-

, Yet anoth'er object 'bfthis inventibn is to prois of a construction capable of 'positively'support ing the light "oni't'he barrel or 'brech"of "thegun against movementouttof an adjusted "posi tion'as a 'result'of afiring' of the gun.

Anotnerobiect of this invention is' to rovide a flash" light "attachment for agenda which means for ad'j'ustingithe' flashlight for: 'a tilting and rotatable"movement; and forupand down movement 'relativeto the gun;aretlbckedjinan' adj uste'd positi'on'by :a' single locking member:

A'feature ofthis inventi'onis' found in the pro vision of a fiash light" attachment forthe ibfeech of a gun-"which inciude'sa u=snape clamp'mern ber adaptedto receive the"breech of the in aseated-positionbetween"the'legs thereof. A

flash "light bracket extended lo'ngitiidi'nally oi the-breech; is swivel-1y mounted" on an .adjust';

able member Which'-is supportedfor' up';"and. down movement onone of thelegs of the clamp Further objects, features and advantages bf this 'inventi'on 'will' become apparent from the following description whentaken in connection with the accompanying 'drawirigs, '.'in which Fig. 11 isaperspective vieW'ofthe flas'hilight attachment of this-invention;

Fig. 2 is an enlarged side elevational view of the attachment looking generally toward the right in Fig. 1;

Figs. 3 and 4 are sectional views taken along the lines 33 and 4-4, respectively, in Fig. 2.

With reference to the drawings, the flash light attachment of this invention is shown in Fig. 1 as including a U-shape body member [0, a pair of separable block members H and I2, and a flash light holding bracket I3.

One leg. M, of the U-member -I0,-is of-a shorter length than its other leg -'l6'-:( Figs. 1 and 4). The base or connecting section ll between the legs MandwIiL- liesina-planenormal to the planes ofthe legs l4 and '|6,--andhas-its toporinner surface :formed; with a transverse arcuately shaped recess.ll8rad-apted to receive the underside of a=gun breech, indicatedin dotted lines as l9,-. .-in a-seated position-l- A- pair of clampingscrews 2i,- thread-able: through-the short leg H3 oftheU -member l.0, are engageablewiththe gun breech to clamp the same between the legs I 5 and IB.--

It-is seen,--therefore, that the legs J4 and 16 are in a stradd-led relation with-the-breech l9 and that theleg l6 is-of-a-length toextend-upwardly to substantially- .the topside of the breech Also, with the breech seatedwithin. the recess I3, the base all is-arranged ina-a plane parallel. to the longitudinal: axis of the barrel, to in turnprovide for-.the legs-beingprojected upwardly at right angleswtosuch axis. 5 It is' apparent, of "course, that the body smember l'fl 'inaybe supported in a like-manner on the gun barrel I9a'.

The long.. leg..-l6 is --formed its outer side with? a. vertically extended guideway 22 (Figs. 3 and- B1. A' stud 23 is projected laterally outw'ard-lyf rom the leg ls and is located within the 4)., with the blockfllbeing adapted --for slidable .;up,anddown movement withinthe guideway 22. Long-itudinally; extendedslots or-openings 2 5 areformed in-ethe blocks-H- and l 2- so astobe-in relative alignmentan'd are of-a sizeto loosely receive the stud 23's The adjacent sides-27 and 23 -"0f the blocks I l and 12-; respectively, are r-formed at their upper endswithv mating -o-r corresponding: half- "socket portions 29 which are open at the top sides of the bloeks,asshown-at M (Fig: 4-); A ball member 32, receivable within the socket formed by the socket halves 29, is provided with a stem or projection 33 which extends upwardly from the block members through the socket opening 3 l The bracket structure I3 for holding a flash light 34, shown in dotted lines in Fig. 1, comprises a longitudinally extended frame member at and a pair of clamping rings 31 secured to the opposite ends of the frame member 36. The rings 37 are of a usual split type having hinge connections at 38 and clamping screws 39. The free or outer end of the ball projection 33 is suitably secured to the frame member 36, between the ends thereof, by means such as welding or the like.

With the clamping nut 24 in a loosened position, the block members II and I2 are movable apart from each other to release the block II for a free up and down movement within the guideway 22 in the leg I6, which constitutes an upright stationary support. The adjustable up and down movement of the block member II takes place within limits defined by the length of the slots 25. By virtue of the location of the ball 32 within the socket portions 29, the block I2 and the ball 32 are connected with the block II for up and down movement therewith. Also the separation of the blocks II and I2 opens the socket for the ball 32, whereby the ball is free, for a swivel movement within the socket.

On tightening of the nut 24, the blocks I I and I2 are clamped together in an adjusted position against the leg or upright support I6. As a result of this clamping action, the ball 32 is frictionally secured in an adjusted position between the socket portions 29. To assure the frictional holding of the ball between the blocks II and I2, the inner side 28 of the block I2 is provided with a pair of spaced pads 4I (Figs. 3 and 4) which function as a fulcrum to pivot the block I2 about its lower end, after the pads have been moved into engagement with the block I l, whereby the upper I end of the block I2 is positively moved against the ball 32.

In the use of the flashlight attachment, the flash light 34, which is of a usual cylindrically shaped type, is clamped within the rings 31. The nut 24 is then loosened suificiently to provide for an adjustment of the blocks II and I2 and the ball 32 in the manner above described. Through the adjustment of the blocks, the flash light is adjustable in an up and down'direction relative to the gun breech I9. The adjustment of the ball 32 permits the flash light to be tilted in any direction, and to be rotated about the axis of the ball projection 33 in any tilted position therefor. As a result a complete adjustment of the flash light 34 is accomplished to provide for the light pattern or beam therefrom being directed in a path corresponding to the shot pattern of the gun. The adjusted position of the flash light 34 is positively maintained by merely tightening the single nut 24.

From a consideration of the above description, it is seen that the invention provides a flash light attachment which is of a simple and compact construction and readily secured in a predetermined relation on the barrel or breech of a gun. By merely loosening the clamping nut 24, the flash light 34 is concurrently adjustable in an up and down direction, tiltably adjusted in any direction, and rotatably adjustable in any tilted position therefor. The final adjusted position of the flash light is maintained by tightening the nut 24.

Although the invention has been described and 4 illustrated with respect to a preferred embodiment thereof, it is to be understood that it is not to be so limited, since changes and modifications can be made therein which are within the full intended scope of this invention, as defined by the appended claims.

I claim:
