- This invention relates to a cartridge belt link for 20/60 mm. caliber ammunition, and more particularly to a link of the side stripping type designed to be completely closed during belt pull.
- Side stripping links have definite advantages in automatic gun mechanisms in that they permit higher cyclic rates.
- a so-called closed link where the supporting ring encompassing the round is unbroken however, has the optimum strength to withstand heavy pull.

- a latch member is provided generally as indicated by reference character 16 and. comprises a fiat steel spring of arcuate form and bent backward upon itself at the respective ends. The ends of the member are divided as at 27 to receive a spreading tool and the member is made to be laterally resilient so that it will resume its normal shape after a spreading operation.

- Reference character 25 represents an auxiliary sprocket mounted upon axle A of the feed mechanism.
- This sprocket has as many arms as the feeding sprocket and each arm has faces milled to generate a projection 26 forming a tongue 28 adapted to enter the latch at point 27 where the end is'divided by a slit. Due to the contour of the projection 26 which has the beveled tongue 28 and a wedge portion 29, the latch end will be spread to disengage fingers 24 out from under curved portions and thus release the latch at one side when the divided end of the latch is entered by the tongue 28 and the same is moved forward to cam against the edges by slit 27. The latch will' pivot at the other end. As the cartridge C continues toward the firing chamber the unlatched link will be supported by the web 30 of the sprocket 25 until it is stripped by the stripper (not shown).

10 Claims. (Cl. 8935) This invention relates to a cartridge belt link for 20/60 mm. caliber ammunition, and more particularly to a link of the side stripping type designed to be completely closed during belt pull. Side stripping links have definite advantages in automatic gun mechanisms in that they permit higher cyclic rates. A so-called closed link, where the supporting ring encompassing the round is unbroken however, has the optimum strength to withstand heavy pull. Heretofore a closed link had to be a ramthrough link, i. e. one where the round is withdrawn lengthwise before ramming in the barrel. Side-stripping links are usually opened-sided and, in order to get the equivalent belt pull strength, they must necessarily be made of heavy metal.
The present invention will eliminate those disadvantages by providin a link having a latch member adapted to be pivoted or opened at one or the other of its sides.
it is therefor a primary object of the invention to provide a cartridge belt link having the lightness and strength of a closed link yet having the advantages of a side stripping link.
Another object of the invention is the provision of a link having a latch to complete the encircling of a round that may be unlatched at either end thereof so that the ammuntion may be fed into either the right or left side of the weapon.
A further object of the invention is to provide a link light in weight yet having a belt pull strength comparable to a closed link.
The specific nature of the invention as well as other objects and advantages thereof, will clearly appear from a description of a preferred embodiment as shown in the accompanying drawings in which:
Figure 1 is a perspective view of a cartridge link constructed in accordance with the invention, illustrating the latch member open at one side,
Figure 2 is a top plan view illustrating two links, one with the latch in locked position and encircling a round,
Figure 3 is a front view of a pair of links illustrating one link having its latch locked.
Figure 4 is a section taken along line 44 of Figure 2,
Figure 5 illustrates a special feed sprocket attached to the shaft of a feeding mechanism and showing the manner in which the sprocket cooperates with the belt to unlatch successive links,
Figure 6 is a plan view looking toward the face of one of the fingers of the unlatching device, as indicated by line 6-6 of Figure 5,
Figure 7, is a view looking at the edge of one of the fingers as indicated by line 7-7 of Figure 5; and
Figure 8 is a detail perspective to an enlarged scale illustrating the interlocking of the latch and link.
Referring more particularly to the drawing wherein like reference characters designate like or corresponding parts throughout the difierent views, 1 designates the belt link in its entirety and comprises a substantially semi-cylindrical link member fabricated from a single piece of spring steel and formed to cradle a round of ammunition therein. The link includes a longitudinal body portion provided with a pair of relatively wide inwardly curved arms 4 at the forward end thereof adapted to receive a cartridge C and of somewhat greater diameter. The rear end of the body portion of the link is provided with a pair of inwardly curved arms 5 which are spaced at a lesser diameter than the cartridge C to act as a spring clip tosecure the round end therebetween, as is best seen in Figure 2. The link body portion is centrally cut away to form a bridge 3 between arms 4 and 5. Arms 5 are turned outwardly at the extremities thereof as at 11 and are provided with inwardly struck portions forming detents 6 adapted to be received in the extractor groove D of a cartridge, thus prevent dislodgment of such cartridge. Arms 4 are so formed as to leave a space 7 around the cartridge C as best seen in Figure 3. A pair of inwardly struck up portions 8 on bridge 3 provides support for the wall of the cartridge case at this point. Grooves 9 and 10 are provided to afford rigidity to the longitudinal body portion. The several pairs of arms 4 and 5 curve upwardly and inwardly to the same height.
The upper edges of arms 4 are notched along their outer margins as at 12 and are cut out centrally as at 13, as best seen in Figure 1. The cut 13 is substantially V- shaped at its upper portion thereof and forms a depending channel at the bottom to receive a spreader as will be later explained. A pair of outwardly disposed fingers 14 are thus formed in the arms 4, and the remaining portion 15 is curved outwardly for a purpose to be later described. A latch member is provided generally as indicated by reference character 16 and. comprises a fiat steel spring of arcuate form and bent backward upon itself at the respective ends. The ends of the member are divided as at 27 to receive a spreading tool and the member is made to be laterally resilient so that it will resume its normal shape after a spreading operation. Such resilience is attained by removing major portions of the surface so that the ends are connected by relatively thin bridging members 17, 21 and 18, 22 on respective sides. A diagonal connecting member formed of two thin strips 1%, 20 connect the bridging members substantially as shown in Figure 2. It will be readily seen that respective corners of the latch are free to move laterally to a limited extent. The outer bent edges of the latch member are provided with cut out portions 23 forming a pair of inwardly disposed fingers 24. The material between finger 24 and the body of the member is curved outwardly as at 23 See Fig. 8. The fingers 14 and 24- are designed to mutually interlock and engage under curved portions 23 and 15 respectively as is best shown in Figure 8. A spreading device (to be described later) is employed to spread the latch ends in order to disengage the fingers and open the latch. Since the two ends are mirror images of each other it will be readily seen that the latch may be pivoted or disengaged at their end thereof.
When the latch is interlocked at both of its ends a cartridge is completely encircled. The fingers will nor- 'mally remain at the original position due to the resiliency of the latch.
In order to spread the fingers 24, a special structure is provided on the feeding sprocket of the gun feeding mechanism. This structure will be described in order to better understand how the latch is spread to open the fingers and disengage them from the link. In Figure 5, F represents generally a feed mechanism and G a feed guide chute through which ammunition is guided to the firing chamber of the gun. The link and latch will operate equally well if the ammuntion is fed into either a right or a left hand feeding opening of a gun.
Connecting straps 31 are provided to join the links and form a belt. These straps are essentially of the ring type and pass through the space 7 between the wide arms 4 and the cartridge.
It is apparent from the foregoing, that a unique yet practical belt link has been devised. The links can be reused'since they are not normally damaged. However the latch and link being separate pieces can be replaced individually. The latches can be stamped out with a single operation effecting a savings in manufacture.
' While a preferred form of the invention has been shown and described, various modifications and substitutions of equivalents will occur to those skilled in the art after a study of the foregoing disclosure. Hence the disclosure should be taken in an illustrative rather than a limiting sense; and it is the desire and intention to reserve all modifications within the scope of the subjoined claims.
