Pachmayr, 1220 S. Grand Ave, Los Angeles, Calif. 90015 Filed Aug. 2, 1965, Ser. No. 4.765% 12 Claims. '(Cl. 42-'74) This invention 'has to do generally with associations of firearm recoil pads with the end faces of gun stocks in a manner rendering the pads detachable from fasteners remaining in place within the stocks.

The prevalent practice has been to secure rubber body recoil pads to the gun stocks by screws concealed within the bodies of the pads and requiring removal for separation of the pads from the stocks. This practice has various inconveniences, and if repeated in a given pad mounting, may result in so loosening the screws in the stock as to necessitate reworking the screw holes.

My general object is to provide new forms of pad attachments whereby the pad may be properly applied and maintained to the face of the gun stock, and rendered readily detachable and reapplicable or replaceable as many times as may be desired, without disturbing the fastener anchorage in the stock and without sacrifice of secure attachment of the pad thereto.

Structurally, the invention contemplates forming the pad to include a rubber body and a metallic reinforcing member, e.g. an elongated plate, containing openings adapted to releasably receive and retain the heads of a pair of fasteners anchored Within the stock.

As will appear, any of various forms of anchorages may be employed to securely fix the fasteners within the stock so that the fastener heads will remain at fixed projections from the end face of the stock. Generally contemplated are forms of fastener heads that will be removably accommodated in the plate openings. Among such head forms are those which render the heads transversely defiectable, or resiliently compressible and expansible, so that the heads are frictionally held within the plate openings and may be withdrawn and re-entered by snap-type action.

The invention further contemplates association of one of the fastener heads with the reinforcing member in a manner permitting shifting adjustment of the pad to conform with the gun stock, and a holding action of the other fastener head that locks the pad in adjusted position.

The manner of accomplishment of these and other objects of the invention will be understood from the following detailed description of illustrative embodiments shown by the accompanying drawings, in which:

FIG. 11 is a fragmentary sectional view showing a further variational form of fastener and attachment to the pad; and

FIG. 12 is a section taken on line 1212 of FIG. 11.

First in reference to FIGS. 1 and 2, which show the attachment of a pad generally indicated at 10 to the end face 11 of a gun stock 12, it will be understood that the pad, and particularly its rubber body 13, may be made in any of various forms, with or without laminations, peripherally conformed to the outer periphery of the stock face 11. Merely as illustrative, the pad is shown to include an outer portion 14- having a surface 15 engaged against the stock face 11, the central area of the pad having ribs 16 defining cavities or recesses '17 to implement the cushioning qualities of the rubber. The body of the pad may include one or more laminations 14a, e.g. of somewhat harder rubber, or engagement against the gun stock.

The pad contains within its outer portion 14 a metallic reinforcement plate 18 illustrated in FIG. 2 to conform generally with the shape of the pad and having spaced

continuous flanges

19 and 20 projecting into the rubber body. The plate is bonded to the rubber by molding the latter about the plate so that the latter is fully embedded and is spaced, eg the thickness of the lamination 14a, from the inner face of the pad to allow for its compression between the plate and surface 15 when the fasteners are engaged.

The pad is detachably held to the gun stock by a pair of fasteners generally indicated at 21 and 22 permanently set into the stock and projecting through openings in the plate 18 into the pad cavities 23. To retain the pad against unintentional release, it may have with one of the fasteners eg 21, a locked association requiring release from the other fastener 22 before the pad can be bodily disengaged.

The fastener 21 is shown to comprise a tube 24 terminally slotted at 25 within its inner end and also slotted at 26 within its outer end. The fastener 22 also has a t-ubular body 27 similarly slotted at 28 and 29. In its application to the gun stock the tubular body 24 of fastener 21 is inserted part way into a straight bore 30 drilled into the usually wooden stock, together with an expander pin 31, see FIG. 3, having an enlarged frusto-conical wedge end 32. As inserted, the wedge end 3-2 of the pin projects out of the end of the tube 24 and is seated against the end 33 of the bore. The tube or sleeve 24 then is driven inwardly against the wedge to the full depth of the bore, causing the split end of the pin or sleeve to expand into the wood or other material of the stock to permanently anchor the fastener in place. The opposite split end of the sleeve is formed with circularly spaced projections or lugs 35 at opposite sides of the splits 26 and at closely predetermined spacing from the stock face '11.

The pad plate 18 contains an opening 36 shown in FIG. 4 to be shaped with diametrically opposed slots or recesses 37 registerable with the fastener lugs 35 when the 9 pad is turned from alinement or registry with the end face 11 of the stock.

Referring to FIGS. 6 and 7, the tube or sleeve 27 of fastener 22 similarly receives a pin 38 having a wedge head 39 acting to expand the inner end of the tube at its slots 29 into fixed anchorage within the stock. Here the outer end of the fastener is annularly enlarged at 40 except for the interruptions by slots 401 so as to be radially contractable and expansible when inserted or withdrawn through a circular opening 41 in the plate 18.

Attachment of the pad to the stock is effected by first thrusting the fastener lugs 35 through the plate aperture slots 37 with the pad in turned orientation relative to the stock face 11. By then exactly alining the pad and stock, lugs 35 overlap the plate between slots 37, thus to lock the pad against removal by straight outward pull. The pad and plate are given sufficient longitudinal flexibility to permit thrusting the lower aperture 41 against the slotted end of the fastener body 27, thus to deflect the enlargements 40 and cause them to have snap expansion at the inside of the plate when the latter is brought to the FIG. 6 position. As will be understood, the spacing of

lugs

35 and 40 from the stock face 11 is such as to maintain the pad tightly held to the stock face, assurance for which is given by projecting the pad rubber at 14a somewhat beyond the plate 18, thus to permit some peripheral compression of the pad as the fasteners become fully engaged.

FIGS. 8 to illustrate a variational form of the invention fastener 45 may correspond in structure and function to the previously described fastener 22, and wherein fastener 46 may be similar to fastener 21 except that instead of being slotted longitudinally at its outer end, the tube 47 is transversely notched at 48. Here the pad reinforcement plate 49 has an aperture 50 sufficiently larger than the tube 47 to permit longitudinal shifting of the pad after insertion of the fastener head into the opening to bring the inner side of the opening into the slot 48, thus to lock the pad against outward separation while permitting shifting of the pad to exact peripheral correspondence with the stock face 11. After so positioning the flexed plate about the fastener head 47, the aperture 51 is thrust over and past the expansible slotted head 52 of fastener 45, causing the head to snap expand at the inside of the plate. In FIGS. 8-10, the plate 49 is shown to have a peripheral flange 49a turned toward the end face F of the pad. But as before, the rubber is bonded to the plate by molding against the fully embedded plate and with the latter spaced at S from the pad face F to allow for compression of the rubber.

FIGS. 11 and 12 illustrate a further variational embodiment of the invention in which a solid fastener pin 53 corresponding in function to the previously described

fasteners

21 and 46, is anchored into the gun stock by turning the threaded and terminally tapered shank 54 of the pin into an initially somewhat smaller diameter unthreaded bore drilled in the stock, so that the pin taps into and becomes strongly anchored into the wood of the gun stock. Here the pin has an annular recess 56 at the inside of head 57 insertable through an enlarged portion 53 of an aperture in the reinforcement plate 59. As shown in FIG. 12, the aperture has a reduced extent 60 which may be shifted into the pin recess 56 to lock the plate against outward separation. A second fastener then to be engaged may correspond to fastner 45 having its type of 4 anchorage in the gunstock, or otherwise as in correspondence with FIG. 11. By reason of its threaded accommodation within the stock, the pin 53 is adjustable to accurately position the head 5'7 from the end face of the stock.
