Application September 27, 1946, Serial No. 699,623

Generically this invention relates to .a sheathed knife, but it is more especially directed to means for preventing accidental separation of the knife from the scabbard.

One'of the principal objects of this invention is the provision of means for securing knives such as hunting, camping or fishing knives against displacement from their scabbards while being carried suspended from a belt or the like, and lo'st. ""Another object of this invention is the provision of manually releasable means for locking the knife in its sheath and preventing accidental displacement of the knife by contact of bushes or other objects therewith.

A further important object of this invention is the provision of a locking element and mounting arrangement therefor in a manner such that said locking element is not only concealed by but constitutes a reinforcement for the scabbard.

With these and other objects in view, which will become apparent as the description proceeds, the invention resides in the construction, combination, and arrangement of parts, hereinafter more fully described and claimed, and illustrated in the accompanying drawings, in which like characters of reference indicate like parts throughout the several figures, of which:

Fig. 1 is a side view of a sheathed knife with parts broken away and in section and showing my improved device in looking position.

Fig. 12 is an edge View of Fig. 11.

Fig. 13 is a fragmentary side view of ascabbard and knife with parts broken away and in section showing another form of locking member.

Inth illustrated embodiment characterizing this invention there is shown a knife I of the hunting type, compris ng a blade 2. a handle or Claims. (01. 224- 2) "hilt 3, and sheath 4, in the presentinstance, corresponding-in contour to the shape of the blade 2, which is adapted to be concealingly re.- ceived therein, and which is embodied in the form of the invention illustrated in Figs; 1-6.1. 5.

- The scabbard or sheath 4 comprises what may be termed, for purposes of description, a back portion or wall 5 and a front portion or wall.6 constructed of leather or other suitable material. Positioned on said back portion spaced fromv the edge thereof is a spacer I constructed of leather, rubber, or other suitable'material and formedat one end with a tapered portion 8 for a purpose hereinafter more fully appearing. The spacer element forms the blade receiving space or chamber 9 and maybe varied in size .or thickness in accordance with the particular blade; ;to-' be sheathed as Will be well understood. A spring wire lockingiand catch element 10 substantially conforming to the configuration-of spacerfl is adapted to engage the edge surface of saidspacer, one end of said locking member being longer than the other and adapted to extend beyond the open end-of the'scabbard and is formed at its-end; with an outwardly and downwardly extending portion forming the catch or locking element II. ,The front portion 6 is superimposed on spacer] and saidtop 6 and bottom 5 are united, in the present instance, by the stitching l2. The circumscribing edges of the said front and back sections; are

'united by stitching l3, and this closes the channel or chamber 14 housing and securing thelocking member 'l'll therein. While the parts have been shown as united by stitching l2 and I3; if desired, these parts, may be united'by lacing with thread or thong along saidlines of stitchingas will bewellunderstood. i 1 ".iThe quillon ,or guard l5 of the handle or hilt '3' is;1in the present instance, formed withl a "rectangular opening: l6 of a size to receive the ;-:catch l I so that as the knife is p'rojectedin the scabbard or sheath the member .I0 is deflected .towardthe tapered portion'8. by manual pres- ;sure thereon causing the catch ll ,to pass through and as it clears opening IE it will spring .into locking position with respect to the seat'fll thereby locking the knife in the sheath until .said catch is manually depressed to permit'gwithidrawal of the knife as desired. In order, olpa'rry the sheathed knife or supportingly secure the ,scabbardto abelt or the like abelt receiving lo pjl8'l'isj formed with a piece of leather jorfthfe like upon itself and securing its ends to said scabbard adjacent its open end by stitching,

riveting, or in any desired manner.

Anothe f rm 9 he n eiien is perms '3 Figs. 7 to 12, inclusive, comprising a knife l9, including a blade 20, handle or hilt 2|, and quillon or guard 22, formed with a slot or opening 23 for a purpose directly more fully explained. A sheath 24, substantially conforming to the configuration of the blade which it is adapted to encase, comprises a back portion 25, and a front portion 26. A spring rod catch member 21, substantially similar to catch member ID heretofore described, is adapted to be mounted in a pair of spacer members 28 and 29 formed by folding a piece of leather or other suitable material around the short portion 28' and curved portion 29 of said member 21 and securing the overlapping portions to the undersurface of back portion 25 by stitching 3|. It will thus be noted that members 28 and 29 not only form a housing for and means of securely mounting the spring member 2'! in operative position, but constitute spacers for the back and front portions 25 and 26 of the scabbard when said portions are united at their edges by stitching 32. It will also be noted that spring member 21 at its lower end is bent inwardly forming catch 33 and then downwardly and outwardly forming the cam face portion 34. Also said member 21 is bent outwardly as at 35 so that as the knife I9 is sheathed or projected into the scabbard 24 the edge 36 will engage cam face 34 deflecting member 21 and as the guard 22 is seated with respect to said scabbard'catch 33 automatically engages thereunder securely locking knife I9 in the sheath or scabbard 24, as heretofore ex- :plained in connection with Fig. l.

A belt loop member 36 similar to member 18 is secured to scabbard 24 by rivets :31 or in any suitable manner.

In Fig. 13 is illustrated another form of locking means wherein a locking member 38 is formed from spring wire or rod material, similar to locking members In and 21, except that it is bent to form spaced loops 39 adapted to receive rivets 40 to secure itto the sheaf portion 4| and to the upper or opposite sheaf portion, shown as removed. Said member 38 at its lower end r The operation of the different forms would seem to be sufficiently clear from the above description as to warrant further explanation unnecessary. 'It is obvious that the form of the locking catch asshown in Figs. 1 and 13 can be constructed similar to the form shownin Fig; "7

without departing from the principle or scope of the invention.

From the above it is apparent that my invention without in any way departing from the principle or scope thereof is utilizable in different forms, wherein a manually releasable locking element is carried by the scabbard adapted for locking engagement with the quillon or guard to secure the knife within the scabbard against displacement and loss, under certain conditions adapted for utilization as an attachment without material modification to existing structures, yet simple in construction, manufacturable at a negligible cost, and efficient for the purposes intended.

Although in practice it has been found that the form of the invention illustrated in the accompanying drawings and referred to in the above description as the preferred embodiment is the most efficient and practical, yet realizing that conditions concurrent with the adoption of the invention will necessarily vary, it is desired to emphasize that various minor changes in details of construction, proportion and arrangements of parts, may be resorted to within the scope of the appended claims without departing from or sacrificing any of the principles of this invention.
