BAYONET Filed March l, 1943 HErbErLE ILE@ 27 v btommpj Patented Jan. 16, 1945 UNITED STATES FATENT OFFICE (Granted under the act of March 3, 1883, as amended April 30, 1928; 370 O. G. 757) 1 Claim.

The invention described herein may be manufactured and used by or for the Government for governmental purposes without' the payment to me of any royalty thereon.

The present invention relates to bayonets.

Among the objects of the invention are the following: simplification of manufacture, lessening of cost of production, increase in speed of production, elimination of forging operations in the production, and the application of punch press and stamping operations in the fabrication of bayonets.

The specific bayonet hereinafter described in detail as an example of an embodiment of the invention enables the accomplishment of the above stated objects.

In the accompanying drawing forming part of this description of an embodiment of the invention,

Referring in detail to the drawing, the bayonet includes a blade I, a guard 2, a tang 3, a T-slot member 4, a pommel 5, pivoted arm 6 carrying bayonet hook 1 and scabbard hook 8, spring 9, and hand grips I0 and II.

The blade I, which extends forwardly from the guard 2, and the tang 3, which extends rearwardly from the said guard, are one continuous piece of steel, and are formed from a bar of steel having the same or approximately the same width and thickness as the tang. The point of the blade and the cutting edges I2 and I3 of the blade are formed by grinding on one or both sides of the bar of steel, depending upon whether single or double bevelled cutting edges are desired.

In the fabrication of the blade and tang, long bars of steel of the width and thickness of the tang, or slightly larger in width and thickness than the nished article, are cut into lengths long enough to form the blade and tang as an integral piece. Each of these lengths or pieces is cut out or punched out on a punch press at the rear end of the tang (see Fig. 2) to provide the open space in the tang above the outline indicated by the letters A, B, C, D, E, F, G, H, J. If desired, the cutting of thev bar into suitable lengths and the formation of said space by punching may be accomplished in a single punch press operation by the use of suitably made dies. From the foregoing it is to be noted that the blade and tang are integral; that in fact the tang is a continuation of the blade to the rear of the guard 2 and that the dimensions of the width and thickness of the blade at its rear end are the same as the corresponding dimensions of the tang from the guard 2 to the line HJ, where the width becomes irregular, due to the cut out part, but the thickness continues uniform from end to end of the tang.

The space at the rear end of the tang, produced by the above described cutting out operation, enables the tting of the T-slot member 4 to the tang while remaining ush with the top thereof and the operation of the bayonet catch 'l within said space.

Referring more particularly to Figures 2, 3, 4, 5, 8 and 9, the T-slot member 4 is formed fr'om a single piece of metal, such as steel, for example by blanking, punching and bending operations. In Figure 8 the formed T-slot member 4 is shown in perspective. It comprises a .top portion I5 having the slot I6, and side portionsg I'I and I8 which turn inwardly, below the top, towards each other to form respectively bottom portions I9 and 20. These bottom portions stop short of meeting, to provide the slot 2l of sufficient width to accommodate the tang 3. The depending ange 22 proceeds downwardly from the bottom portion 20 and serves as a means for securing the T-slot member to the tang. The width of the flange 22, measured from the top of slot 2I to the bottom of the flange, in the embodiment of the invention shown, is the same as the width ofthe tang, at the pommel end, although it may be somewhat less, so long as sucient width is provided for securely attaching the T-slot member 4 to the tang 3.

As will be seen from an inspection of Figure 8, the T-slot member 4 provides the T-slot 23 which continues lengthwise of the member, except that the slot i5 forming part thereof in the top of the member stops short of the end of the top of the member to provide the shoulder 24 (see Fig. 2).

The T-slot member 4 is assembled on the tang.

3 as shown in Figures 2, 4 and 5, the flange 2.2..

of the T-slot member 4 resting flat against the side of the tang 3 and being secured thereto* by welding, brazing, silver soldering or riveting or in any other suitable manner.

The pommel'liV (see Figs. 2, 3, 9, 10 and l'l),

consists of a metal plate having. a.slot 25 and a T-slot 2S into the bottom of which thev slot 25-l opens. T-slot 26 has the same dimensions as T`slot 23 in T-slot member 4, except that' it is bevelled at its entrance atI 2.1 to facilitate en- .tranceof the bayonet lug on the ri'e. The length of the slot 251 from the bottom to the point where it opens into the TI-slot 26' is the same as the Widthof the tang 3- at its end. The Width of the slot-25 is such as to-enable the pommel 5 toAbe iit over the end of the tang 3 as shown in Figures 2 and 8l The pommel 5'is welded', brazed' or sil'- ver soldered to thetang 3.

|The dimensions of the T-slot member 41, of the pomme] 5, and of the cut-out portion at the end of the tang 3 are such as to enable these parts when assembled to occupy the relative'positions shown in Figures `2` to 5. In thisl assembly T`slot 25 in pommel 5 registers with T-slot 23 in T-slot.

member 4, and both of these Ti-slot's-are'of such shape and dimensions as to accommodate and engage with the bayonet lug 28 (see Fig. l) onA the-upper band 29 of the rie 30k The forwardprojecting lip 3l of the lug Zit-ntsl beneath (see` fixed to the rifle as shown in Figure l. A slot' 43' is provided lengthwise and midway between the edges` of the guard. The width of this'slot1i`s` such as'to enable the guard to be slid over thel tang or blade into the position-it is to occupy. The length of the slot 43l is much longer than the width of the tang or blade, and when the guard is assembled with the tang or blade-this excess in length of the slot over the.' width ofthetang or blade is equally, or aboutvequall'y, divided at each end, as shown in Figures 2' andI 6i Theopen portion atleach end of the slot A4'3fi`sfor'tl'iepurpose of receiving the two' scabbard mouth piece hooks which are usuallypresent on bayonet scabbards. Thescabbard hook .8 (see Figs. 2, 65 and '7) is located in that open portion of the=s1ot 43 which is on the cutting edge side'lZ' of the blade. The said open parts of slot 43 may be slightly chamfered on the blade side, as indicated at 44, to facilitate entry therein of the scabbard mouthpiece hooks. The guard 2 is i'lXedV or` secured in position by brazing, welding, silver soldering. or. riveting.

Arm 6 (Figs. 2 to 4) carries bayonethookv I` and scabbard hook 8. An elevation of this arm is shown in Figure 2 and a bottom View is shown in Figure '7. This arm comprises two portions, which depart slightly from being 180 degrees from each other, as shown in Figure 2, with an enlarged portion 45 where the two portions of the arm meet. A hole 46 is provided through the enlarged'portion 45, and through this hole passes the bolt 41 which holds the grips HJ and Il on the tang. The size and shape of the hole 46 is such that the arm 6 pivots or rocks freely on the bolt 4l.

The arm 6 lies externally of the tang 3 and rides against it during its motion in pivoting or rocking about the bolt 41 as a fulcrum or center; In the embodiment of the invention shown',I that portion of the arm 6 which carries Figures 4. and 5.

the bayonet hook 1. is somewhat longer than thatportion4 which carries the scabbard hook 8, measured from the opening 46.

The bayonet' hook l is shaped'. as. shown` in Figure 2L and is offset inwardly as shown inY Figure 3 to bring it within'. the space inV thetang dened by the outline BCDE.' Hook 'lfmoves freely within this space and in Teslot. 23 of T-slot member 4 whenk the arm G. rocks onthey bolt 411'.. The

The purpose of spacing'the; thumb piece 48' from the edgeof.` the tang 3` is to'permit the arm 6 to be rocked bythe pressure of the thumb thereon in disengaging the bayonet hook l or the scabbard hook 8 respectively from behind the bayonet lug 281on the rifle or from the mouth piecel hook (not shown) on the bayonet scabbard.

Arm 6' with its enlarged portion 45' and with bayonetlhook l, portion 49, thumb piece` 48 and scabbardhook 8; is formed from one piecer of metal, such assteel, by suitable stamping,- punching, bending and shaping or formingoperations. These named parts, therefore, constitute an. integral piece of metal, and by integral or integrally formed in the appended" claims is tobe understood integralV not only in the sense of being made of or fromv one piece of metal` but integral in the sense ofv constituting one body such as'- may be made up byweldingf, brazing or soldering separate parts together asf one `unitary structure;

lA spring 9 is fixed at one of its ends' to thel tang 3at 5E! and presses' against the part-of.' the arm 6.that carries the scabbard hook 8;- said' spring urging the arm 6i clockwise as .viewed in Figure 2. Spring` 91 may be ofthe. form.` shown'. in Figure 2 or of any other suitable form, or'

evenY otherwise positioned, so l'ong as` it accomplishes the purpose intended herein. In' Figure 2 the parts are shown as if some pressure had; aflready been applied to thumb pieced; and this for the purpose of exposing more fully to View so much of Tslotmember 4fas appears in said ligure. The above mentioned` clockwise motion of the arm 6 is arrested by part' I9'(vsee Figs. 4 1

and 5) acting as a stop for said arm..

Hand. grips I0. and l I extend from'thelrear.V of

guardk 2 tothe pommel 5; being. recessedL tor passv beneath' the portions |'9` and 2UV as*v shown in.v

These hand grips are'- held in'l position on tang 3 by means of a llister head bolt 41 Whose head and nut are respectively indicated by the numerals 5| and 52. This bolt passes through a hole in each hand grip and through a hole in the tang 3 intermediate its ends, and besides holding the hand grips in position, it also serves as the pivotal support, or center of rotation, of the arm 6. The inner surface of hand grip l0 ts at against the tang 3 and the flange 22, a clearance cut being made on the inside of said hand grip to accommodate the flange 22. Hand grip Il is provided with clearance out 53 to accommodate arm B and spring 9, and with a clearance out for portion 49 of arm 6, in such a manner as to permit motion of these without binding. These handgrips may be made of wood, metal or of a suitable thermoplastic or thermo-setting compositiont What is claimed is as follows:

A bayonet comprising a blade and tang formed of a continuous metal bar of substantially the same width and thickness, the tang portion of which has at least one substantially flat side and a cutaway portion at its rear end, a two armed lever pivoted intermediate its arms to the ilat side of said tang for a rocking movement intermediate the ends ofthe tang, a bayonet hook on the rear arm of the lever and oiset therefrom and extending into the cut-away portion of the tang into alignment with said tang, and a scabbard hook carried by the front arm of said lever, an elongated member having a depending elongated flange secured to the tang on the side thereof opposite the lever, said member having elongated slots therein substantially the length of the member, said slots anked by oppositely disposed bayonet lug engaging grooves and said member positioned in the cutaway portion of
