American Fastener This invention relates to cartridge belts for machine guns, and more particularly to a tool for attaching tapered V-shaped metal end tangs employed to facilitate the insertion of said belts into a machine gun.

One object of the present invention is to provide a tool of the above nature which is adapted to force a pair of prongs projecting downwardly from the upper leg of the V-shaped tang through the cartridge belt, and then to bend said prongs rearwardly and upwardly so that they will pass around a neck in the lower leg of said tang and penetrate the belt a second time, thereby producing a very strong permanent connection between the tang and the belt without the use of staples or rivets.

A further obj ect is to provide a tool of the above nature in which the bending of the tang prongs is accomplished by forcing said prongs against curved anvils mounted in the die bed.

A further object of the present invention is to provide a tool of the above nature in which the lower leg of the V-shaped tang which initially supports the belt is resiliently mounted on a spring-cushioned shelf supported above the die bed.

A further object is to provide a tool of the above nature which will be simple in construction, inexpensive to manufacture, easy to operate, compact, ornamental in appearance, and very efficient and durable in use.

With these and other objects in view, there has been illustrated on the accompanying drawings one form in which the invention may conveniently be embodied in practice.

In the drawings,

Fig. 1 represents a top plan view of the cushioned shelf for supporting the machine gun belt tang.

Fig. 2 is a side sectional view of the same taken along the line 2--2 of Fig. 1, and showing the punch, the shelf, the die bed, and an anvil extending into said shelf, prior to the insertion of the belt between the legs of the belt tang.

Fig. 3 is a transverse sectional view of the same, taken along the line 3 3 of Fig. 1.

Fig. 4 is an enlarged longitudinal sectional view showing the punch, the shelf, and an anvil in their relative operating positions just prior to the first step of forcing the prongs of the belt tang into the belt webbing.

Fig. 5 is a similar view of the same after the prongs have been forced downwardly by the punch through the belt into engagement with the curved recesses in the anvils, and have been curled rearwardly thereby below the belt.

2 Claims. (Cl. 153-1) Fig. 6 is a View similar to Figs. 4 and 5, showing the parts as they appear after the punch has depressed the shelf fully against the die bed, and has caused the prongs to be bent upwardly and passed part way through the belt into its nal position.

Referring now to the drawings in which like reference numerals denote corresponding parts throughout the several views, the numeral II) indicates a die bed having a pair of aligned slots I I, I2 at its opposite ends for permitting said die bed to be attached to a supporting plate (not shown) located therebeneath.

The numeral I3 indicates a rectangular vertically movable cushioned shelf located above the die bed Il] and having two pairs of vertical bores I4, l5 passing entirely therethrough, said bores having reduced neck sections I6, Il for fitting around and guiding two pairs of bolts I3, I9 which are mounted to slide vertically within the bores I4, I5. The bolts I8, I9 are provided at their lower ends with flat iillister heads 2B, 2i, which are normally held against the shoulders of the lower ends of the neck sections I5, Il by means of four coiled compression springs 3B, 3|, the bottoms of which engage the tops of the neck sections I5, Il, and the upper ends of which engage a pair of internally threaded bushings 22, 23, which are slidably fitted into the upper ends of the bores I4, I5. Y

The bushings 22, 23 are adapted to receive the threaded ends 24, 25 oi the bolts I8, I9 and also the lower ends of a pair of machine screws 26, 21 passing downwardly through the shelf I3, said screws26, 21 being seated in apertures 28, 29 formed in said shelf I3.

By means of this construction, it will be seen that when the shelf I3 is pushed downwardly by means of the punch 53 to be hereinafter described, it will be cushioned by the springs 3U, 3i and will be limited in its downward movement by its engagement with the top of the die bed l0.

As fully disclosed in my copending application, Serial Number 475,855, filed February 15, 1943, patented October 17, 1944, No. 2,360,501, the V-shaped belt tang III to be attached to the end of the cartridge belt 48 is provided with initially diverging legs IIE, -the upper leg 45 having a pair of struck-out prongs 5I, 52 depending therefrom.

In order to cause the prongs 5 I, 52 (which preferably have pointed V-shaped extremities) to be bent rearwardly and upwardly after being forced through the cartridge belt 43, provision is made of a pair of rectangular anvils 32, 3'3 projecting 32, 33 are also engaged by a pair of horizontal set" screws 31a, 31h located in tapped horizontal apertures formed in opposite sides of the die bed Ill:I In order to position the narrow looped pointi- 43 of the belt tang 44 during the operationv ofattaching said tang to the belt 48, provision is made of a U-shaped end plate; 38' which is? at-.V tached to the forward end of fthe shelf `'I 3 bymeans of a pair of machine screws 39, 40.

The end plate 38 is provided :with'a tapered slot* 4I, below which the shelf I3 has a semi-circular transverse groove 42 for receiving the looped'end 43 of the belt tang 44. The lower leg 46 of the belt "tang WT-isV providedl with an upstandingfstop lugf41 which' is slightly inclinedy rearwardly 'so as to -enga^ge the endfor the beltAv 48` and limitthe frward'rnovement thereof during insertion; Thef' lower leg 46'ofithe belt tang44 is vprovidedwith two pairs of longitudinally spaced rectangular aperturesf49g' 492 and l"59; 5having partitions 1 or 49249 arelrinyerticalalignment with',l andrare adapted to permit-.the passage ofrthe pair of elongated-1f pointed-'prongs 5 I ;i 52v of the upper 'leg- Hry when said-"leg-45 :is-forced downwardly, as clearly shown in Fig. 4.

In order to centralize the tang 44 on the shelf I3 during the operation of the tool, provision is made of a pair of side guide bars, 64, 65, the guide bar 64 being relatively higher than the guide bar 65 to permit the tang and webbing to be easily inserted into position from the opposite side of the shelf. The'guide bars (Wand-65 are adapted to be held detachably in position upon the shelf I3 by means of machine screws 66, 61.

While there has been disclosed in this specification one form in which the invention may be embodied, it is to be understood that this fbrm is shown for the purpose of illustration only and that the invention is not to be limited to the specilicv disclosure,- but may be modified and embodied in various other forms without departing from its spirit. In short; the invention includes all the modiications and embodiments coming within the scope of the following claims.

Having thus fully described the invention, what `s-.claim'ed as new, and for which it is desired to securefLetter's z Patent is:
