Application filed November 2, 1898. Serial No. 695,313. 7

To all whom it may concern:

Be it known that I, EDWARD Gr. PARKHURST, a citizen of the United States of America, and a resident of Hartford, in the county of Hart- 5 ford and State of Connecticut, have invented certain new and useful Improvements in Cartridge-Packets, of which the following is a specification.

This invention relates to packets for holding together in a unitary form suitable for storage and transportation a series of cartridges of the number ordinarily required for charging the magazines of repeating breechloading firearms. Such a packet is technically I known as a cartridge-clip when it is inserted in its entirety into the magazine of the firearm, and it is technically termed a magazine-filler when it is applied to the mouth of the magazine so as to transfer its file of car- Previous to being inserted in or attached to the magazine of the firearm the functions of a filler and a clip are identicalthat is, to hold the packet of cartridges securely together until required for use, so 2 5 that they may be readily and quickly handled and applied at either end to their respective magazines.

The objects of the present invention are to provide a light, simple, inexpensive, convenient, and effective locking-packet, which may be made from a single piece of sheet metal and which securely holds together the desired number of cartridges in a unitary packet without adding materially to their weight or bulk; to adapt it so that it may be reversibly applied to the magazine; to provide for retracting the locker of that end of the packet which is applied to the magazine; to retain the packet securely in position during the charging operation; to adapt the packet to be ejected from its charging position when empty-as, for example, by the closing movement of the magazine-cover, and to so construct and organize the members of the packet that it will resiliently clasp theheads of the terminal cartridges of the packet.

Figure 1 of the drawings is a rearward view, and Fig. 2 is a side view projected therefrom, showing my improved cartridge-packet containing a file of five cartridges and applied as a magazine-filler in charging relation to the magazine of a firearm of the Krag-Jorgensen type, the characteristic features of that magazine being herein shown sufliciently to enable the charging operation thereof to be understood. Fig. 3 is a rearward view, in enlarged scale, showing the construction of the filler. Fig. i is a side View in section, taken substantially along the line t 4 of Fig. 3, showing the packet engaging a file of five cartridges. Fig. 5 is a front view showing further details of the construction of the packet and illustrating the manner in which the resilient bifurcated ends of the cartridge head -guiding flanges of the packet are contracted so as to clasp the terminal members of the file of cartridges between them. Fig. 6 is a fragmentary view of the upper end of a cartridge-packet, showing the locker in its closed position when the packet is empty. Fig. 7 is an underneath view of the packet of Fig. 4, illustrating the manner of gripping and locking the terminal cartridges.

As a unitary articleof manufacture and commerce my improved cartridge packet is formed from a single piece of sheet metal, preferably spring -steel, of which the side flanges 8 and 9 are turned over to form the cartridge-head-receiving channel 10. This channel, along with the rearward wall 12 of the packet, should be curved to suit the cartridges to be used or the form of packet to be made, so as to bring the points of the file of cartridges as close together as their form will permit. In order to form the resilient arms 8 5 or tongues 13 and 14:, which perform the combined functions of locking the cartridges in position in the holder-when used as a cartridge-packet and of retaining the filler in position relative to the magazine while transferring the cartridges thereto, the rearward wall 12 of the body of the packet is slit or punched out along the lines 15. The ends of these tongues project somewhat beyond the ends of the rear wall 12 and are turned forwardly and downwardly to form the locking faces or hooks 16 and 17, which project forwardly across the ends of the cartridge-channel 10 and substantially at right angles thereto, so that when the packet is filled with cartridges 0 the locking-faces project over the rims r of the terminal members of the file of cartridges, thus locking the ends of the packet. The combined locker- detent tongues 13 and 14 are preferably bent backwardly at 18 and 19 out of the plane of the wall 12 in order to allow of the free lateral movement of those tongues, to provide a clearance for the cartridgeprimers, and to form a channel for receiving and permitting the escape of the dust, grit, and other extraneous substances which are liable to enter and clog the channel, tending to impede or to obstruct the freedom and uni formity of the passage of the cartridgedieads along the channel. The ogee- bends 18 and 19 appreciably shorten the tongues, thereby drawing their tapering sides away from the lines of severance 15, and thus providing a clearance for the ends of the tongues where they pass between the clasps 22 and 23 and project over the channel 10.

In the use of this cartridge-packet, whether as a clip or a filler, it is intended to unlock the desired end by means of an inclined o r wedgeshaped actuator, and in order to engage with that actuator the locker- dctents 13 and 14 are provided with the arms 20 and QLrespectively, which are so located with relation to their respective ends of the packet and to the actuator as to bring the foremost cartridge of the packet into proper relation to the magazine when the corresponding locker-detect is retracted by its actuator, as shown in Fig. 2. The arms 20 and 21 are also utilized as a means for engaging with a recessed seat in the magazine or receiver of the firearm, each serving, in connection with its resilient tongue, as a detent for retaining the packet in the desired end wise relation to the magazine when discharging the cartridges therefrom. In order to adapt these arms to this pur pose they are beveled or turned upwardly at each edge, as shown in Figs. 1 and 6, in the arc of a circle, which may or may not extend entirely across the respective tongues, as herein shown. Correspondingly beveled or rounded recesses or seats for the arms are provided in the magazine or packet-holder of the gun immediately adjacent to the lockeractuator thereof. so that the arms of the leading locker-detent tongue after sliding along the inclined actuator snap into the aforesaid curved seats, thus enabling the tongue upon being withdrawn from service as a locker to serve in the capacity of a detent for retaining the packet against accidental or unintentional dislodgment. The resiliency of the lockerwith the closing magazine-cover in the ejecting operation, its ends are beveled or rounded at 2 1, so that the magazine-cover in its closing movement upon reaching the position shown in dot-and-dash outline in Fig. 1 will engage with the rounded or beveled end of the packet-body and eject it upwardly from its seat. By shutting the cover quickly, as is usual and desirable in the operation of the gun, the emptied packet will be ejected clear of the firearm and ordinarily will fall on the right-hand side thereof. After the arms 20 or 21 are dislodged from their detaining-seats 31 in the firearm the ejecting operation is facilitated by the contracting action of the locker against its inclined actuator, which thus supplements the action of the magazine-cover in ejecting the emptied packet from the firearm.

The slitting or shearing of the rear wall 12 incidental to the formation of the locker-detents 1 3 and 14 serves to bifurcate the ends of the packet, thus forming the oppositelydisposed resilient pairs of clasps 22 and 28 for the rims of the terminal cartridges. These bifurcated ends of the cartridge-guid ing channels of the packet are bent slightly toward each other, so as to clasp the edges of the rims of the terminal cartridges with suflicient tension to impart a suitable degree of firmness to the packet, thereby holding the terminal cartridges firmly in a radial relation to the curve of the packet-body, thus holding the series of cartridges close together at their points and making a firm yet sufficiently-flexible packet for convenient handling and transportation. This clasping capacity compensates for the slight variations in size attendant upon the commercial manufacture both of the cartridges and of the packets, as it is exceedingly dilficult, if not impossible, to manufacture them so accurately to gage that all cartridge-heads would fit equally well in any one or all of a large number of packets. The cartridgerim receiving channels of these packets are made equal to or slightly wider than the diameter of the largest cartridgerim, as shown in Fig. 5, since it is allowable to have the intermediate cartridges of the packet somewhat loose, the integrity of the packet as to form and tightness'being secured by the clasping of the rims of the terminal cartridges by the resilient bifurcated ends of the packets. When the terminal cartridges are thus held, even with slight tension, they are much less liable to cramp in the flanged guideways or channels of the packet, since the tension, however slight, serves to sustain them in proper radial relation to the curved body of the packet. This edgewise clasping of the terminal members of the file or packet of cartridges serves also a useful purpose in connection with the charging of magazines like those of the Krag-Jorgensen type, as

shown in Fig. 2, in which, on account of the absence of the cooperating resistance of the follower-spring of the magazine, the cartridges are, if allowed to fall freely upon the retracting of the locker, liable to displacement, which, especially in the case of cartridges having projecting rims like those herein shown, would block the feeding operation of the gun by the interlocking of the rims.

In employing this cartridge-packet as a clip within a magazine from which the cartridges are fed upwardly by the spring of the follower or elevator it is important to have the tension of the clasps slight enough to be readily overcome by the elevator-spring, or means may be provided in the firearm for springing the bifurcated ends of the leading pair of clasps slightly apart, so as to free the cartridges from the edgewise tension of those clasps upon inserting the packet into the magazine, or when it arrives at its discharging position.

The projecting ends 25 of the rear wall 12 of the packet may also be utilized either with or without the cooperation of the clasps 22 and 23 in holding the terminal cartridges with added firmness in their desired positions by bending them slightly forward into the plane of the cartridge-head-receiving channel 10, as best shown in Fig. 6. The inclined abutments 11 of the lockers 13 and 141 by bearing against the outer edges of the beveled rims v of the cartridge-heads, as shown in Fig. 4,

may also be utilized to assist in holding the file firmly in position with the points of the cartridges close together. Thus by the organization of this packet the desired clasping tension may be applied to the terminal cartridges by the clasps 22 and 23, the inclined abutments 11 of the locker-detents, the forwardly-bent ends 25 of the wall 12, or by the cooperation of all these members, as may best suit the form of the cartridges, the type or construction of the magazine, or other particular circumstances or conditions under which this packet may be employed. These resilient members, while holding the cartridges with sufficient firmness under normal conditions, will yield to inequalities due to differences in size, to dents, bruises, or dis tortions of the cartridge-heads, or due to the presence of dust or grit in the channel of the packet, and will yield also to the definite pressure of the operators hand in the charging operation.

It is not essential to the satisfactory operation of the locker- detent tongues 13 and 14 that they be each provided with a pair of arms 20 and 21, since these tongues would perform all of the functions herein contemplated for them with a certain degree of excellence, even if each locker-detent were provided with but a single arm at one side thereof. I prefer, however, whereve'r permissible, to provide each tongue with a pair of these locker-arms arranged on opposite sides both for utility and symmetrical appearance. These arms when thus employed in pairs serve, in conj unction with the corresponding locker-actuating inclines, to open the lockers more freely and squarely, besides holding-the packet more securely and squarely to its seat on the magazine when serving as detents, as shown in Fig. 2; nor is it essential that the locker- detent tongues 13 and 14 shall be bent backwardly out of the plane of the wall 12 in the ogee 'I prefer, however, to bend the locker-detents backwardly at 18 and 19, as hereinbefore described and as shown in the drawings. In order to distinguish clearly the outlines of the various members, the width of the slots along the lines 15 is somewhat exaggerated, so that those lines appear in the drawings as slots.

The improvements made by me in the Krag- J orgensen .firearm to adapt it to cooperate with the packet herein described form the subject-matter of a contemporaneously-pending application. They comprise a holder 26 for receiving the packet and supporting it in proper charging relation to the magazine, wedge-actuator inclines 30 for unlocking the lower end of the packet, a recessed seat 31 for receiving and detaining the arms 20 and 21 "of the packet, and a deflector 33. These devices are so organized in correlation with my present packet as to support the latter not only in suitable charging relation to the magazine, but in such a relation to the swinging magazine-closer that the latter upon being closed after the operation of charging the magazine will engage with the lower end of the emptied packet and positively eject it clear of the firearm.

This improved cartridge-packet is or can be exceedingly light, as it requires only an area of thin sheet metal sufficient to. form a channel for the cartridge-heads. None of that area is wasted by lapping or doubling the metal; but all is utilized and distributed to best advantage among the several members for the suitable performance of their respective functions, thus constituting a packet combining the maximum of efiiciency with the minimum of weight and cost. A packet containing five cartridges of the United States Government caliber weighs two thousand one hundred and live grains, while the weight of the empty packet is but approximately seventy grains, or about one-thirtieth of the entire weight of the filled packet.

I claim as my invention- 1. A cartridge-packet made in an integral piece, comprising a body portion forming a cartridge-head-receiving channel and having the ends of the said bod divided to form a plurality of resilient side members at each end of the packet for receiving the opposite sides of the cartridge-rims, and a resilient locker at each end of the packet, between the said side members, formed integral with the rearward wall of the cartridge-channel, the lockers being each provided with a shouldered end projecting over the cartridge-rims, and with a pair of oppositely-disposed actuatingarms adapted to cooperate with unlocking and clip-retaining devices of the firearm.

2. In combination with a packet-holder having an inclined locker-actuator, and a retaining recess therefor at the base of the incline, a cartridge-packet made in an integral piece, comprising a body portion forming a cartridgc-head-receiving channel, and a resilient locker at each end of the body portion, parted from the rearward wall of the cartridge-channel and bent backwardly to a plane out of the plane of the rearward wall of the cartridgechannel, the lockers being each provided with a shouldered end projecting over the cartridge-rims, and with a pair of oppositelydisposed actuating-arms adapted to ride over the incline of the locker-actuator and to drop into the recess at the bottom of that incline to resiliently sustain the clip in charging position and to return backwardly out of the recess over the incline when the packet is ejected from the holder.

3. The combination of a cartridge clip or packet, having a positive locker, and having the end of its cartridge-hcad-receiving channel resiliently contracted for yieldingly retaining the cartridges in the clip independently of the positive locker.

4. A cartridge-packet comprising a cartridge-head-receiving channel, bifurcated and contracted edgewise at its end to form a resilient clasp for the edges of the cartridgerims.

5. A cartridge-packet comprising a cartridge-head-receiving channel, having a resilient locker-detent formed from, and integrally with, its rear wall, the end of the said rearward wall adjacent to the locker being bent into the plane of the cartridge-head-receiving channel to form resilient clasps for the cartridge-heads.

6. A cartridge-packet comprising a cartridge-head-receiving channel, having the end of its rearward wall rounded in substantial conformity with the end of the terminal cartridges in the packet, and having a resilient locker-detent formed from and integrally with the rear Wall, with its end projecting centrally over the head of the terminal cartridge, the projecting bifurcated end of the rearward wall upon each side of the locker being bent forward into the plane of the cartridge-headreceiving channel to form resilient clasps for yieldingly retaining the cartridges in the clip after the retraction of the locker.
