SCABBARD Application September 13, 1940, Serial-No. 356,638

7 Claims.

The present invention relates to scabbards for bayonets or the like and consists in an improved metal fitting for the open end of the scabbard and an improved joint construction whereby the fitting is secured to the body of the scabbard.

Heretofore scabbard fittings have been milled or otherwise machined from solid steel forgings, an operation requiring a great amount of time and skill on the part of the machinist as well as the employment of expensive machine tools. Moreover, a high percentage of waste has resulted on account of flaws in the forgings uncovered in the machining operations.V

The object of the present invention is to provide a bayonet tting comprising essentially sheet steel parts which may be punched and formed at a high rate of speed with the greatest accuracy and uniformity of quality from selected sheet steel. The ttng of' our invention comprises a plurality of suchsheet steel blanks, all of simple shape which l'end themselves to high speed punching and which may be easily formed in dies by bending, and then crimped or swaged and spot-welded in a rigid assembly. Included with the principal sheet metal parts of the fitting are hooks which may be of high grade toolA steel. These are small in themselves and can also be produced at high speed from strip stock of small dimensions and are permanently and securely incorporated into the tting as rigidly and securelyas if they were an integral part of the same.

In general we have succeeded in designing a scabbard tting' for high speed production on a mill basis as distinguished from the prior production of what amounts to. hand-Wrought littings considered a necessity heretofore. We have, moreover, made this quantity production possible without in any way sacrificing the necessary strength ofthe tting or otherwise impairing its` eiciency and reliability in the most exacting conditions of use.

For purposes of illustration the fitting of our invention is disclosed in its adaptation to such a scabbard as that shown in our prior application Ser. No. 312,192 filed January 3, 1940*. The body of that scabbard comprises a water-proof sheath l0 of thermoplasticl material molded to shape and including plies of canvas or other tough textile fabric to give the scabbard high tensile strength and toughness. The side faces of the scabbard are flat terminating in rounded.

shoulders which merge into integral longitudinal edge ribs Il. The body of the scabbard as shown in Fig. 7 includes a plastic insert in the form of a hanged collar i2'. This is inserted within the scabbard after the molding operation and is hanged outwardly over the outer end of the scabbard and beneath the' top plate of the fitting as will be presently described.

The fitting itself comprises three members which are stamped as fiat blanks out of sheet steel, two hooks shaped from bar stock of tool steel or the like, andy a wire loop which is yformed readily from a steel wire blank.

The top plate I3 of the fitting may be stamped out of mild sheet steel about e inch in thickness or thereabouts. The plate is generally rectangularin contour with rounded corners and rearwardly extending ears i4 which are bent upwardly and forwardly to form bearings for the wire loop f5 by which the scabbard is attached to the belt of the user. The top plate is. provided with an elongated slot Ifo to receive the blade of the bayonet and with square apertures to receive the hooks l1, one locatedl adjacent to each end of the slot i5.

Beneath the top plate i3 of the fitting is a sleeve portion which includes an inner plate 20 originally stamped out of mild sheet steel about .03 inch in thickness or thereabouts in substantially the shape of the blank shown in Fig. 2. The blank is generally rectangular having two right angle shoulders or steps in its side edges upwardly projecting intermediate portion 24 in the body of the plate.

The outer plate 43 may similarly be formedf from a generally rectangular at bank of sheet steel as shown in Fig. 4 and again this blank is preliminarily shaped by having its side portions 4I bent forwardly into parallel relation but with slightly wider spacing than the corresponding wings of the inner plate. Shoulders in the side walls dene a projecting central portion 42 in the body of the plate and a tongue 113 projects downwardly from each of its side walls.

The hooks I'I, which in the finished scabbard make detachable connection with a catch on the bayonet itself, are swaged from straight bar stock of substantially square or half-round cross section and each is formed with an outwardly offset notched head providing an outwardly projecting shoulder under its head and an outwardly projecting shoulder in the inner wall of the body of the hook as shown in Fig. '7.

The inner and outer plates are assembled to make the sleeve portion of the tting, together with the hooks II which are located as suggested in Fig. 6, that is to say, the side walls of the outer plate 40 embrace or overlap the side walls of the inner plate and the hooks I'I rest at their lower ends upon the shoulders 22 of the wings 2| of the inner plate. Moreover, the outwardly projecting shoulders of the hooks themselves rest upon the upper edge of the side walls 4I of the outer plate 40 because the length of each hook below its shoulder corresponds exactly to the length of the second step in the edge of the inner plate. At the inner sides of the posts the shoulders are caught beneath the top plate I3. y

YHaving assembled the parts loosely in this relation they are forced together by suitable swaging dies and their side walls crimped upon each other and upon the bodies or shanks of the hooks I'I. The wings 2I of the inner plate are rolled into a rib of substantially semi-circular cross section as shown in Fig. 10 so that the shoulder 22 is fully eiective to support the end of one of the hooks I1. Above the shoulder 22 the side wallof the inner plate passes inside the shank of the hooks I1, as shown in Fig. 9. The side walls of the outer plate are formed into longitudinal ribs also substantially semi-circular in cross section. These ribs in their upper part enclose the hooks Il and in their lower part conform exactly to the smaller ribs formed in the inner plate as shown in Fig. 10. In this operation the tongues 23 and 43 of the two plates are brought into substantial superposed relation. The projecting portions 24 and 42 of the inner and outer plates respectively are flanged outwardly in a common plane as best shown in Fig. 8 to underlie the top plate and the parts of the fitting are positively secured in the relationship thus established by spot welding these outturned flanges of the inner and outer plates to the under face of the top plate I3. It will be seen that the top plate I3 overlies the inwardly projecting shoulders of the hooks I'I, and, accordingly, when the top plate is welded in place on the sleeve formed by the plates 20 and 40 the hooks are rigidly and permanently interlocked in the iitting against all possibility of being withdrawn.

The complete fitting is now assembled upon the scabbard and for this purpose the longitudinal ribs II of the scabbard are cut away at the upper end of the scabbard for a distance sufiicient to clear the enclosed shank of the hook I1 and the side wall of the inner plate 20 which lies inside the shank. The shank and this inner wall form in eiect, an obstruction to the open channel formed in the lower part of the sleeve of the fitting which is shaped to receive the rib II of the scabbard. The ribs of the scabbard thus nt into the lower part of the sleeve up to the lower ends of the hooks. Square shouldered notches are cut in the ribs at a distance lower down the scabbard corresponding to the length of the wings 2I of the inner plate or on a line corresponding to the lower edge of the sleeve. The tting is nally secured in place by bending inwardly the superposed tongues 23 and 43 into each of these notches forming a double-ply hook as shown in Fig. 7 and in this manner a very strong union is eiected between the tting and the scabbard all without the formation of projecting angles or corners which might catch and disturb the connection in use.

It will be understood that the employment of the anged collar I2 is optional and that where this is used the dimensions given include the thickness of the flange of this insert, but if the insert is not used the top plate I3 would t dlrectly against the end of the scabbard.
