In the drawings and the following specification, only as much illustration and description is given "of the details of the firearm and its component parts as is necessary to adequately describe the structures comprising the subject matter of this divisional application. For a more complete understanding of the operation of the details of the firearm, hereinafter referredv to as a gun, and other associated parts or mechanism, attention is directed to the above-mentioned co-pending application Ser. No. 325,405 or the above-enumeratecl patents, among which Patent 1,525,065 is among the more important.
The particular firearm to which the instant invention is readily applicable and which has been shown in the attached drawings in the preferred embodiment of the invention, is a caliber 37 mm. automatic cannon, details of which are illustrated in said co-pending application Serial No. 325,405 but it is the present invention is not limited in its application to this gun only since it has ready application to other types of firearms and particularly automatic firearms.
Guns of the nature illustrated and described are used for various purposes and in adapting the gun for use to certain of these purposes, it is found that various quantities of ammunition are desirable or required notwithstanding the fact that the same gun is used for all such purposes. Accordingly, the present invention provides means whereby ammunition may be fed to the gun by a plurality of suitable interchangeable means, each holding various quantities of ammunition. Said means are adapted to be interconnected by quick-detachable securing means having component parts common to the various interconnectible means to simplify the interconnectibility of said means. I
It has been accepted practice for certain types of firing of guns of the nature illustrated to supply a small number of rounds or cartridges to the feed channel of the gun by mounting five or ten cartridges in a so-called rigid feeder; To properly support this type of feeder, the present invention provides a loading tray detachably secured to the gun at one side of the feed channel by novel securing means, the purpose of the tray being to not only align but also support the weight of the feeder assembly consisting of the feeder and cartridges while the assembly is being fed to the feed channel of the gun.
Convenience of manipulation and operation limits the capacity of a rigid feeder and, should a greater quantity of ammunition be desired for automatic feeding to the gun than is possible to supply with a rigid feeder, th present invention provides a magazine adapted to contain and support an articulated-link type feeder which may be compactly arranged in the magazine when the feeder is filled with cartridges to provide a larger number of cartridges for feeding to the gun than is afforded by a rigid feeder. The number of cartridges which may be held by the magazine may vary since the magazine may bemade of such size as to hold any desired number of cartridges within reasonable limits. The invention includes attaching means for the magazine similar to those on the loading tray whereby the loading tray and magazine may be quickly and easily interchanged, the securing means on the side of the gun serving to secure either the loading tray or magazine thereto.
The invention still further provides a loading plate adapted to be detachably secured to the magazine to facilitate the insertion of a loaded feeder or feeder assembly into the magazine while loading the same prior to attaching the magazine 'to the gun. The loading plate is provided with securing means similar to those on the side of the gun whereby the securing means on the mag azine readily co-engage with the securing means on the loading plate to detachably connect the two together.
It will thus be seen that the present invention provides mechanism which enhances the versaillustratin to be understood that quick-detachable interconnecting means for the various separable means described above are common to all of said means whereby the interchangeability of the same may be accomplished quickly and without requiring the use of tools or other operating mechanism other than the latches carried by certain of the means.
The gun, particularly as shown in Figs. 1 through 3, is shown in its horizontal position which may be regarded as normal. However,
the gun may be used at various angles of elevation or depress-ion or even inverted or it may be turned laterally. The terms horizontal and vertical as herein used are to be understood as relative terms which. are applicable when the firearm is in its normal position as shown. Furthermore, the terms front and rear are to be similarly considered in a relative sense with respect to the end of the gun from which the barrel projects being the front of the gun and the opposite end the rear of the gun Details of the invention will now be described with reference to the accompanying drawingsin which the gun is shown to include a breech casing 2, a barrel 4 projecting from, the front end thereof, and a feed box 6 mounted on the upper side of the breech casing. The feed box 6 contains members of the cartridge feed mechanism and is provided with a transverse feed channel 6* into which the cartridges and the feeder, either rigid or articulated-link type, may be fed from left to right. To permit access to the parts of the feed mechanism, the feed box 6 is provided with a movable top cover I 2 which is preferably entirely removable and which is also provided with projecting longitudinal tongues l2 on its opposite edges which tongues fit correspondingly longitudinal grooves 6 6 in the side walls of the feed box, these grooves being readily shown in Fig. 2. The grooves 6 6 terminate in openings extending upward to the top edgeof the feed box to permit the cover to be moved vertically downward to bring the tongues 12*, l2 into re istry with the grooves 6 6 and a spring latch l3 on the cover serves to hold the samein place. A supplementary cover I2 is mounted on the cover l2 to accommodate certain moving elements inthe feedbox.
Detachably connected to one side of the feed box adjacent the feed channel G ls a cartridge supporting device which is shown in Figs. 1 and 3 'as being a shelf-like loading tray I4. As will be hereinafter madeclear, a magazine may be substituted for the loading tray. The loading tray mechanism. The tray I4 and the feed box 6 j are provided respectively with connection devices which serve to connect them, but which permit them to be readily disconnected and separated. The connection devices may be varied as to detailsand as to relative arrangement of parts but,
as shown, the tray I4 is provided with vertical walls [4 and l 4 which are normally immediately adjacent the outer face of a bracket I5 o the left wall of the feed box, and the said walls are assaes apertured to receive two pairs of studs l-=-, l5 projecting from the said bracket 15. The studs l5 [5 are notched at their bottoms and the tray [4 is provided with two spring-pressed latches l6, it each having two teeth 16, Hi adapted to enter the notches in the studs to hold the tray in place. The two teeth are mounted on a vertical rod H3 which is pressed upward by the spring. The latches l6, 16 are provided with buttons I1, I! by means of which they can be pushed downward to permit disconnection and separation of the parts.
While the loading tray M has primarily been described for use with a rigid feeder assembly, it is to be understood that said tray may also be used to facilitate the introduction of a flexible or articulated-link type feeder assembly into the feed channel. However, in the preferred embodiment of the invention, a magazine is provided which is particularly adapted to accommodate a flexible link type feeder assembly which magazine is illustrated with its various details in Figs. 4 through 10.
The gun includes firing mechanism which need not be described in detail as it is similar to that illustrated in said (Jo-pending application Serial No. 325,405 and also Browning Patent 1,525,065. For present purposes, it is sufficient to point out that the firing mechanism is operated by a trigger lever 66 adapted to effect firing when moved rearward with respect to the feed box.
The flexible type feeder comprising interconnected articulated links shown in Figs. 4 through 6, 9 and 10 and which is primarily adapted to be accommodated in the magazine, to be described in detail, is designated in its entirety by Ed. It comprises a number of intermediate links T5, a leading link "I6 and a trailing link 11, Details of the feeder are claimed in my divisional application Serial No. 437,853, filed on even date herewith. Each of the links has a body portion 78 which is preferably formed of sheet metal and is bent to the shape of an inverted U as shown in Fig. 6. This is of the same size and shape as the main body portion of a rigid feeder which may be substituted with equal facility for the flexible feeder, the rigid feeder being shown and described in detail in said co-pending application Serial No. 325,405. The depending side flanges of each body portion 78 are provided with notches or recesses 18 Fig. 10, for receiving a cartridge, each of the side flanges being thus provided with two spaced legs W and 18 Fig. 10. Two of the legs, as for instance the two legs-18 are offset so as to fit between the adjacent legs 78 of the next adjacent link. The legs that thus overlap are joined by pivot pins or rivets 19, 79. The several connecting body portions l8, l8 constitute the main body portion of the articulated-link feeder. Each of the links also has a spring clip 89 for holding a cartridge, this clip being similar to the spring clips provided on the rigid feeder described in said co-pending application Serial No. 325,405.
As illustrated in Fig. 6 particularly, each cartridge has an annular groove till provided in the projectile thereof. Each spring clip 80 is generally U-shaped, and each leg of the U-shaped clip is provided with a slot or bifurcation 80 to form a pair of resilient fingers in each leg of the spring clip. Each of said fingers is provided adjacent its outer end and near one edge with a struck-in portion or detent 89. When the cartridge is placed in the notches or recesses 18*- of the feeder, the spring clip 80 engages the cartridge in such a way that a pair of oppositely 3 disposed detents 8!) engage in the annular groove of the cartridge to not only releasably hold the cartridge within the feeder but also prevent movement of the cartridge with respect to the feeder in a direction substantially longitudinal of the cartridge. Since the detents 80 are all mounted on separate resilient fingers and are thus independently movable, the other pair of opposed detents Bll not engaged in the groove 80 will engage the outer surface of the cartridge to afford positive contact between the cartridge and all of the resilient fingers provided on each spring clip 86 to prevent movement of the cartridges from the feeder except at the proper time for feeding the cartridges respectively to the breach chamber. The detents 80 are so placed on the spring clip 80 that the cartridge may be reversed end-for-end in the feeder and one pair of oppositely disposed detents 80 will always be in proper position to engage the annular groove 80 of the cartridges to correctly hold each cartridge with respect to the feeder for reception in the feed channel of the feed box.
Riveted or otherwise secured to the top of each U-shaped member '58 of the feeder is a flat plate 15* which has the same cross-sectional size and shape as the top plate of a rigid feeder such as illustrated in said co-pending application Serial No. 325,405. A somewhat similar plate 16* is provided for the leading link 76 and a somewhat similar plate Tl is provided for the trailing link TI. The several separate plates 15 Hi and l! are in alignment when the articulatedlink feeder is straight and they constitute the top plate or guide structure of the feeder. The top plate 16 of the leading link differs from the others in that it is considerably longer to facilitate the entry of the feeder into the feed channel of the gun. The top plates '15 and Hi are notched at one side at '15 16 for purposes of being engaged by stop and positioning pawls il- -lustrated in detail in said co-pending application Serial No. 325,405, and the details of which are not believed to be necessary for a proper understanding of the present invention. Each top plate 15 16 and 11 together with the corresponding body portions 18, are transversely slotted at 75, 16 and 11 which slots are provided for engagement by feed pawls on the reciprocable feed slide 45, Fig. 2, the details of which are also set forth in said above referred to co-pending application Serial No. 325,405. The pivoting of the U-shaped members 78 adjacent the ends of the legs of each U -shaped portion provides a flexible feeder which, when coiled as shown in Fig. 5, occupies a minimum of space and, when so coiled, the spacing between the cartridges is only slightly greater than the spacing therebetween when the feeder is in the substantially flat position shown in Fig. 10.
Figs. 4 through 6, 9 and 10 show a cartridge supporting device in the form of a magazine adapted to carry an articulated-link feeder. Complete details of the magazine are described and claimed in divisional application Serial No. 437,850, filed on even date herewith. The magazine comprises two main front and rear plates 84 and 85 which are spaced apart and which are connected by longitudinal tie members 86, 81, 88 and 89. The two plates are also connected at the top by a horizontal flat plate 90 w ch is seated at its ends in slots in the plates. The front and rear plates 84 and 85 are provided respectively with brackets 84* and 85' which have vertical portions adapted to engage the outer face of the bracket I5 on the 94 has upstanding end portions 94*, 94
serve to hold the magazine on are spring-pressed 1 the plates 84 and 85. 95 and 96 project through suitalble apertures 95,
latches 9|, 9|, which are the same in construction 7 as the spring-pressed latches l6, l6 of the loading tray. These latches are controlled by means of buttons '92, 92 which correspond to the buttons l1, I! of the loading tray. It will be clear that the magazine can be put in place on the gun in the same position as the loading tray, the same studs I5 I5 being utilized for holding it. Pref- I erably the plates 84 and 85 are provided with lugs 84 and 85 which project toward the right to engage the casingof the gun and thus more rigidly support the magazine.
The rear face of the plate 84 and the front face of the plate 85 are provided with helicoidal grooves'which are of the same shape and are in longitudinal register with each other, these grooves being adapted to receive respectively the points and the heads of cartridges mounted in an articulated-link feeder such as the feeder 14 already described. In the particular magazine shown, the grooves in the plates are of sufficient length to accommodate l5 cartridges but it will be understood that the invention is not in any way limited to the particular number of cartridges shown.
Secured to the plate 90, at the bottom thereof, is a guide member 90 having a T-slot 99 therein adapted to receive and guide the plates TIP, I5 and I6 constituting the guide structure of the feeder. The guide member 90 projects at the right beyond the edge of the plate 90, as clearly shown in Fig. 4, and the slot 90 is open at the top in this right hand projecting portion of the guide member. With the magazine in place, the guide means 90 in the magazine and the guide means provided in the feed channel for the feeder are in register with each other.
For carrying the magazine when it is separated from the gun, there is provided a handle 93 having pintles at its ends which are seated in bearing apertures in the plates 84 and 85. When the magazine is in place on the gun, the handle may be in the position shown by the full lines in Fig. 5 but, when the handle is to be used for carrying the magazine, it is swung upward to the position shown in dot-and-dash lines in Fig. 5.
For convenience in loading the magazine, there is preferably provided a magazine loadin plate 94 which is shown in Figs. 9 and 10. The plate which carry pins 94 94 which are similar to the pins I5, l5 of the gun. This enables the loading plate 94 to be attached to the magazine and to be held by the same latches 9|, 9| which normally the gun. The bottom of the loading plate 94 is so positioned that the loaded feeder is supported in exactly the proper position to enable the top plates of the feeder to readily enter the T-slot 90 in the guide member 90 of the magazine. In order to conveniently start the loading operation, the top .plate of the trailing link of the feeder is placed in the open portion of the slotllll as shown in Fig. 9. The entire articulated-link feeder assembly is then pushed into the magazine, assuming a coiled position determined by the helicoidal grooves in the plates 84 and 85.
In order that the cartridges and the feeder may are rigidly connected with a longitudinal pivot pin 91 seated at its ends'in bearing apertures in The free ends of the fingers and 96 -providedin the plate 90, Figs. 4 and 9. Springs 98, 98 serve to bias the pivot pin and the fingers for movement in clockwise direction so as to tend to hold their end portions between the f rst two cartridges as shown in Fig. 5. .This serves to accurately position the entire feeder assembly, that is the feeder and the cartridges, with the foremost engageable portion thereof in predetermined relationship with the magazine. With the construction shown the foremost engageable portion of the feeder assembly is the foremost feed slot, that is the slot 16 in the leading link. Thi definite positioning of the feeder assembly is important for the reason that the slot 16 must be in proper position to be engaged by a pawl on the feed slide 46 when the magazine is attached to the gun, details of which are shown in said co-pending application, Serial No. 325,405. a
The fingers 95 and 96 would interfere with the loading of the magazine if allowed to remain in their normalypositions. In order that the fingers 95 and 96 may be conveniently withdrawn to perrmit loading, one of the fingers, as for instance 95, is provided with a tail portion 95 which is adapted to be engaged by a pin 93 on the handle 93. "By moving the handle toward the right to the position shown by full lines in Figs. 9 and 10, the
pin 93 is brought into engagement with the tail portion 95 of the'finger so as to elevate both the fingers to the position shown by full lines in Fig. 10. This makes it possible for the entire feeder, with the cartridges therein, to be pushed into the magazine without any interference by the fingers 95and 96. As soon as the feeder and the cartridges arein place, the handle is released and the fingers then move to the position shown by dotted lines in Figs. 5 and 10 so as to accurately position the cartridges and the feeder. The fingers and'96 do not prevent withdrawal of the feeder and the cartridges from the magazine, but they do resist such withdrawal and they thu prevent any accidental movement of the feeder and cartridges out of the magazine during such handling as may be necessary prior to the placement of the magazine on the gun.
When a magazine and an articulated-link feeder are used, it is necessary or at least desirable,
to provide a chute at the right side of the gun for receiving and guiding the empty portion of the feeder. A suitable chute for this purpose is shown at 99 in Figs. 4 and 5. For holding the chute in place the right side of the feed box is provided with brackets 190, I09 which are aperadapted to extend through suitable holes in plates 99- of the chute.
It will thus be seen from the foregoing that the. present invention provides accessories, certain of which are adapted to be detachably secured to either the gun or another accessory to render the gun useful with a plurality of different sizes and types of feeders whereby the gun isrendered useful for a wider range of firing conditions depending upon Whether a short burst or a longer interval of sustained automatic firing is desired. For short bursts, a rigid type feeder of five or ten rounds capacity may be fed to the gun by means .of the loading tray. Ifa larger number of rounds is desired, the'magazine may be used for the loadbe accurately positioned in the magazine, there ing tray and detachably secured to the gunbythe same means as the loading tray. 7
7 To facilitate the loading of the magazine, a
loading plate is provided to support and guide the flexible feeder assembly to the magazine, the loading plate being adapted for detachable engagement with the magazine by means identical in construction with those for securing the magazine to the gun. The novel detachable securing means are common to all of the various interconnectible accessories and the gun to permit the ready interchangeability of said gun and various accessories to render the gun adaptable for the wider range of uses described in the foregoing.
