12 Claims.

This invention relates to re-arming tools and particularly to a re-arming tool for connecting or disconnecting cartridges to metal links which interlock with each other and the cartridges for forming an ammunition belt.

The tool is so constructed that, through the operation of a lever in one direction, a cartridge is inserted in the nested links with the projectile and cartridge ends in aligned relation to adjacent cartridges or, through the movement of the lever in the same direction, a cartridge may 'be withdrawn from the links, thereby separating the belt at that point. The tool embodies a receiver of channel section having upwardly projecting prongs at one end for receiving the nested links. A channel-shaped carriage having inwardly directed flanges at the front end is longitudinally movable within the receiver.

A lever is pivoted to the receiver having a slotted portion extending thereabove and therebelow, with a portion therebelow in position to be grasped by the hand of the operator. A downwardly extended handle portion is provided on the end opposite to that having the upwardly projecting prongs toward which the lever is moved by the operator. A link interconnects the lever and the longitudinally movable carriage. The pivot connecting the lever to the links is adjustable in the slot therein so that the end of the link may be positioned at the upper end of the lever above the receiver -or may be moved to a position below The link end is retained in either end of the slot by a toggle operating spring.

When the link is above the receiver, the movement of the lever toward the handle portion moves the carriage forwardly. When the link is below the receiver, the same movement of the lever toward the handle portion pulls the carriage to the rear. When the carriage is moved forwardly, the inwardly projected flanges of the carriage abut against the heel of the cartridge to force the cartridge forward into the links retained by the upwardly projecting prongs on the forward end of the receiver. When the cartridge is to be removed, .the slot in its heel is disposed over the flanges at the forward end of the carriage so thata movement of the carriage away from the links will withdraw the cartridge therefrom, thus releasing the links and separating the belt of cartridges. A spring is provided about the pivot of the lever to urge the lever away from the handle portion of the receiver into position of operation.

Accordingly, the main objects of this invention are: to provide a re-arming tool which operates to connect or disconnect a belt of cartridges through the movement of a lever in the same direction; to form a channel-shaped receiver from a stamping having a downwardly extending handle on one end and upwardly extending prongs on the other, with a carriage operated by a link and lever which move the carriage in forward and retracted position by a movement of the'lever in the same direction; to form a re-armingtool with a forwardly and rearwardly movable -carriage which is connected by a link to a point above or below its pivot point to produce the movement of the carriage in either direction by the same movement of the lever; to provide a re-arming tool having a receiver and an axially movable carriage with a lever which is interconnected by a link to the carriage and which is movable on a lever to a carriage advancing or retracting position by a bell crank which retains the links in either of the said positions; and, in general, to construct a re-arming tool from stampings which is simple in construction, positive in operation, and economical of manufacture.

similar to that illustrated in Fig. 2., showing a modified form thereof.

The re-arming tool embodies a receiver Ill'which is made from a channel-shaped stamping having a web portion II and flange portions [2 and I3 extending upwardly at the 'sides. Toward the front of the web a pair of spaced prongs |4 extend upwardly in position to engage the end of the annular portion 5 of a connecting link l6 which, with the cartridges, make up the belt. A forward pair of upwardly extending spaced prongs 1 are closer than the prongs l4 for engaging the smaller annular portion |8 of the link |6"so as to prevent the nested links from moving forwardly or backwardly in the receiver when sup ported thereby between the prongs. portions l9 at the rear end of the tool are disposed closer together and terminate in a downpair of side flanges 26 having the forward por tions thereof bent inwardly at 21 for engaging the ends of the cartridges to either push or pull the cartridge relative to the nested links I6. The projecting portions of the flange abut against the end of the cartridge when pushing the cartridge forwardly and project within a slot 28 adjacent to thecartridge end when pulling the cartridge from the clip.

An operating lever 29 is secured to the receiver on the pivot 3| about which a spring 32 is supported for moving the lever 29 away from the handle portion 2| of the receiver. A slot 3| is provided in the lever which extends above and below the receiver terminating in the notches 34 and 35 at the ends. A link 36 is supported by the pivot 31 between the flanges 26 of the carriage 22,

the other end of which is attached to a pivot 38 which slides within the slot 33 of the operating lever 29. The link 36 has flanges 4| at the top and bottom enlarged portion bearing serrations on the outer surface by which the link 36 is manipulated to have the pivot 38 moved from one to the other of the notches 34 and 35.

A spring 42 has one end anchored to a flange 26 of the carriage 22 and the other end secured to a tab '43 struck from the link 36. The spring 42 moves from one toggle position to another when the link 36 is adjusted from one tothe other notch 34 or 35 for retaining the pivot 38 in the notch to which it is moved. 'When the link has its pivot 38 in the upper notch 34, a pull on the lever 28 towards the handle portion 2| will move the carriage 22 forwardly to push the cartridge into the clips. When the link 36 has the pivot 38 shifted to engage the notch 35 below the receiver, a pull upon the lever 29 will move the carriage 22 in the opposite direction awa from th clip to withdraw the'cartridge therefrom.

When the belt is to be built up or joined to another belt, the clips |6 are nested together between the prongs l4 and II, as illustrated in the figure, with the cartridge partly inserted therethrough. With the pivot 38 in the upper notch 34, a pull on the lever 29 toward the handle portion'2l pushes the cartridge :forward until the front and rear ends are aligned with the adjacent cartridges to add a cartridge to the belt or to join two belts together. I I

When a belt is be separated, the links 6 are inserted between the prongs I4 and I1, the pivot 38 is shifted to the lower notch 35 and the inwardly projecting flanges 21 engage the notch 26 of the cartridge. A pull upon the lever 29 toward the handle portion 2| withdraws the cartridge from the clip, thereby separating the clips and the belt. c

Figure 4 illustrates the tool in operated position withthe cartridge pushed forward to join the belts or to add a cartridge thereto. Figure 5 "illustrates the tool with the link 36 shifted to The flanged have'the pivot 38 engage the notch 35 and the notch 28 of'the cartridge nested in the flange :portions 21 of the carriage. In this position a Referring to Figs. 6, 7, and 8, a slightly modified form-of re-arming tool is illustrated. A link 5| is substituted for the link 36 and a pivot pin 52 is substituted for the pivot 38. The pivot pin 52 extends through an aperture 53 of a bell'crank 54 which is pivoted on the pivot pin 3|. The bell crank has'a projecting lug 55 which engages one or the other of the depressions 56 and 51 in the lever 29 for retaining the bell crank 54 in either position relative to the lever 29. In the'position illustrated, the bell. crank 54 has moved and re- -tains the pivot pin 52 in the position above the receiver for producing a forward movement to the'carriage 22' when the lever 29 is moved tofrom the clip. It is only necessary to manipulate a the handle portion 58 of the bell crank 54 to change thetool from one which withdraws the cartridge to one which inserts the cartridge, or vice versa. The pivot 52 is positively retained at one or the other end of the slot 59 through the engagement of the boss 55 of the bell crank with one of the depressions 56 and 51 in the lever 29.

Fig. 9 illustrates a slightly different form of 7 structure for retaining the ,link at one or the other end of the slot 33 of the tool illustrated in Figs. 1 to 5, inclusive. In these figures, a coil spring 42 was employed which functioned as a toggle for holding the end of the link at one or the other end of the slot, depending upon whether a cartridge was to be inserted or removed. In Fig. 9 a link 6| isvemploy ed which is similar to the link 36 of the above-mentioned figures, but differing therefrom in having flat surfaces 62 and 63 provided on the end thereof.

A flat spring 64 engages one or the other of the surfaces 62 or 63 for retaining the end of the link in its upper or lower position. Preferably, the'slope of the surface is such as to produce a force on the link which tends to urge the pin 38 beyond the ends of the slot so that the pin will rest againstthe one or the other end of the slots at all times. The link may be supported in the carriage on the rivet 24 and may be prevented from turning on the pivot by a struck-out projection 65.

The tool is entirely self-contained and may be employed in building up, or removing, cartridges from a belt or for connecting or disconnecting belt portions. The tool is rugged, yet simple in manufacture in view of the fact that all of the parts are made of stampings which require a minimum amount of labor and material, thereby materially reducing the cost of the tool.
