. Thislinvention relates to fire armswherein the gun stock is made adjustable relative to the breech, and its object is to providea construction whereby adjustment of the stock;

'may'effect a drop of the stock heel, a droprof the comb, or achange in the e fiective length of thestock to give a perfect fit of the same to the shoulder of the user and relative positioning of the parts to suit that particular individual. i A further object is to provide a. very'simple and rigid construction which is such thatadjustmentmayibe quickly and accurately made, or the gun stock quickly detached, thereby eliminating, the take-down featureand its complication, common to this class ofguns.

Itis also an object of thepresent invention, toprovide a metal stock or grip which is light in weight, very strong and rigid, is cheapto to the accompanying drawings in which F igure 1 isa side elevation of a gun illus trative of an embodiment of the presentinvention, J

Fig. 9 isra section upon the line 99 of As. hown1 the usualvbarrel or barrels ofthe gunwhich hare pivotally connected] as at 2 in the usual manner, to the lock chamber St having the usuallocking-lever forvlockingthe barrel or in Figures 1} and "2, l-indicates 'lbarrelsinlextended position and adapted to enclose firing pins (not shown) adapted tobe operated by the triggers 5 projecting from thelower side of said chamber. Formed integral with the rear end of said chamber 3ras a continuation thereof, is a downwardly curved gripstock or' hand grip 6, the lower end portion of said grip, as shown in Fig. 1, being curved concentrically about aipoint or located in a vertical planeindicated by the ,line 6 shown in Fig. 1, passing vertically through the areacontiguous to one of the triggers 5, said point being substantiallyin the horizontal plane (indicated at 0) of the lower end of said grip. This curved end portion of said grip, may,as shown, be cylindrical in cross-section and formedwith'a slot 7 extending therethrough to receive a tongue 8 formed lntegral with a plate 9 secured to the forwardend of a gun stock 10. This plate 9 is curved in the direction of its length to correspond with the curvatureof saidgrip 6,and:said tongue is formed with an elongated transverse opening or slot 11 through which a screwbolt 12 extends, said bolt having a head 13 at one end to engage one side: of the, stock 6,.and screw-threaded at its opposite end to screw into a screw-threaded opening in the opposite side of the stock,

' The stocklO may, therefore,-be swung about the pointia by loosening the "bolt 12 and moving-its tongue ,8 longitudinally of the slot 7' in thecurved grip 6, and by tightening said bolt, saidstockwill be rigidly secured By'this adjustment ofthe stock-10 upon the curved end. of the grip, the position of the curved grip during such adjustment. This .adjustmentalso raises or lowers theheel or shoulder end 14 of the stock relative to the 1 line of sight falongthe barrel as indicated at d, andat the same time, raises or lowersthe combr15 of the stock relative to said line,

. maintaining. the proper relative position of theseparts andtosaid line, due to thepositionof the point a about whichthe stock swings, and which point does not change but tion of its length and is curved in cross-sec tion to conform to the curvature of thecylindrical lower end portion 18 of the grip 6, this end portion 18 having a rear side which-is 1 straight and is inclined to the vertical, in the direction of its length upwardlytoward the e'ndot the barrel 1. This connectmg member 16 is rigidly secured to the forward end of the stock, by being formed with side flanges down longitudinally of saidend portion 18, 7 thus adjusting the stock toward or from the line of sight withoutfchanging the 'relatlve 19 to overlap the end or" said stock at the sides thereof and with legs 20 provided with openings to receive screws 21. This connecting member 16 is formed with an elongated opening 22 through which passes a bolt 28, said bolt also passing through an openingin the" end portion'18of said grip, with a nut 24; on

its screw-threaded inner end within a recess in the end of the stock, which recess is closed by the securing of the connecting member 16 to the end of the stock.

By loosening thebolt 28, the stock 10 with its connecting member 16 may he slid up or positions of the shoulder endl and comb 15, and at the same time lengthening or shortening the distance from said end 14 tothe rear end of the barrel, due to the upward and for ward inclination of said end 18 and member. 16 forming the abuttingend of the stock.

V As illustrated in Figs. 6 and'7, the gun stock '1na'y be formed hollow, withan integral end-wall 26 which'is inclined upwardlyand for wardlyfthe same as the connecting h for end member 16 of theconstructionshown in Fig. 1", and the opposite end of this stock isjclosed by a plate 27,'curved to properly set against the users shoulder and secured to the end of the hollowstock inany suitable manner. This'stock is detachably and adjust ably secured tothe grip portion'18 in the same manner as shown in F ig.- 4, that is, by

the 'bolt28'passing -through the grip and through the elongated opening 22 in the wall 26, with the nut 24 on the inner end of said bolt. j

. By making the stock 25 hollow, the construction is cheapened in cost and lightened in weight without sacrificing strength or ri jgidity, andthe cost and weight of the gun may be further reduced by also forming the hand grip 28 hollow, as shown Figs. Sand 7 V 9," itbeing'giventhe desired external shape Y and formed to provide the proper end wall 29 to abut the end wall 26 oi the stool: 25. In

the construction shown in Figs. 8 and 9, this end wall of the grip 28 is roughened or corru-' gated and the end wall 26 0t thestock is correspondingly corrugated to give an interlock ing engagement whenthe parts are secured l together by the bolt--23 and provide a rigid connection.

In this construction the walls 26 and 29 are fiat instead of being transversely curved, and, therefore the'stocl; has a longitudinal adjustment only, upon the grip.

" For decorative purposes and to providea firm griptor the'user"s hand and fingers'u'p'on thestock 25 shown in Fig. 6 or upon the grip 28 of Fig. 8, the opposite sides of the stock" may be provided with a roughened area or 7 panel 30, and to provide such an area where the stock 25 is formed with thin sidewalls, a a

slight depression 31 otthe desired'shape and Tsizejofthis area, is formed in eaclrside otthe stock'and a pieceot roughened or otherwise decoratively formed rubber 32101 other suitable 'compositiomis laid into each of these depressions and cemented or otherwise s'ecured in placetherein. Thestock 25 or grip 28 or other part ofthe gun which is formed of thin metal, may thus-be provided with areas of any desired shape and size to give a better hold on the gun and toincrease its attractive appearance,'and suchareas maybe 1 very cheaply applied without materially adding to the-weight or cost of the gun.

In Figure l the adjustment of the stock '10 is secured through a swinging movement, up and down, upon the grip 6, but no lateral movement of the stock relative to the grip is provided for. In the construction illustrated in'Figs. 8 and 9, no lateral adjustment of the stockis secured, said stock being movable up or down along the end wall of the grip only.

' In Figures 4, 5, 6 and 7 the constructions'are such that the stock 10or 25 may be swung laterally as illustrated in dotted lines in Figure 7, up0n the end portion of the grip 18 which is'cylindrica'l in cross-section, the slot 22 in the end wall of the stock being ofsuffi 'cientwidth topermit lateral swinging movement 'of the stock, and the 'nut 2 i'where it seats upon'said wallfbeing curved to conform tothe curvature of said wall andthe axis of such'swinging movement. With this arrangement, the stock may be swung a limited degree, laterallyout of alignment with the gun barrel to fit the shoulder of the particular user and properly position'the barrel relativeto his line of sight along the barrel.

Obviously other changes in the construction andarrangeme'nt of parts, may be made within the scope of the appendedclaims, without departing from the spirit of the invention, and I do not, therefore, limit myself 7 to the particular"construction shown.

Having thus fully described my invention,
