To all whom t may concern.'

Be it known that I, MACK C. BARRY, a citizen of the UnitedStates, and a resident of Atlanta, in the county of Fulton and State of Georgia, have invented a cert/ain new and useful Improvement in Rapid-Fire Guns, of which the following is a specification.

My present invention relates generally to small arms, and more particularly to a rapid fire gun, my object'being to provide certain improvements in the construction and operation of such devices whereby to promote more ready and quick'handlin'g and effective use thereof, as outlined in the following description, reference being made to the accompanying drawings illustrating the preferred form of my invention andforming a part of this specification, andin which- Figure 1 is a perspective View illustrating the complete gun in position ready for operation.

Fig. 2 is a view partly in side elevation, of the upper portion of the gun, one of the barrels being broken away and in section through its breech portion.

Fig. 3 is an enlarged sectional view through the upper portion of the tripod, stand, and the gun frame.

Fig. 4 is a horizontal section taken substantially on line 4-4 of Fig. 3.

Fig. 5 is a detail perspective view of one of the breech blocks and its plunger, and the guide for the latter.

Fig. 6 is a detail perspective view illustratinfr a portion of one of the hammers and its locli'ing dog.

Referring now to these figures, my invention preferably includes a tripod support, the legs 10, 11, and 12 of which are pivotally connected at their upper ends, by pivot bolts 14, beneath the upper horizontal platform 15, one leg, the forward leg 12 in use, being engaged by a spring 16 extending between the same and a bearing block 17 dependin from the platform 15, in order to hold the lleg 12 outwardly in position as the operator seats the tripod, so that adjustment of only the two rear legs 10 and 11 which the operator can conveniently reach, is necessary.

Swiveled upon the platform 15 of the tripod, by a central king bolt 18, is a plate 19 having upstanding side ears 20 to which the lower central portion 'of the gun fratrie 22, thus adapting j ust above mentioned has a forward portion 23 constituting substantially a breech housing and having supporting guides 24 at its upper end for the several barrels 25 of the gun, and is provided with a rearwardly extending portion 26 and with'an intermediate upper support for the magazine orcartridge boxV 27, ythe latter of which is preferably provided with a hinged'top 28 and with its lower end opening downwardly at the rear ofthe breeches 29 'offthe several barrels 25, it being noted that the latter are arranged in horizontal alinement as seen in Fig. 1.

The 'gun frame 21 supports intermediate transverse shafts 30 and 31, respectively carrying the several hammers 32 and the several hammer locking dogs 33, while the rearward extension 26 of the said frame supports a transverse operating shaft 34 and its forwardly extending portion 23 supports a magazine controlling shaft 35.

Each of the several hammers 32 swings forwardly and rearwardly with 'the shaft 30 and is provided with a forwardly projecting lug 36 which the respective dog 33 engages as particularly shown in Fig. 2 to hold the hammer in its rearmost position, the several dogs 33 being movable with their shaft 31, 4at yone end of which is an 'upright a'rrn 37. the upper end of which is `engaged by one end of 4a rearwardly projecting spring 3.8. the rear end of which spring is attached to a portion of t "e frame 21 so ras to normally move the dogs 33 rearwardly toward engaged position. arm 37 being also pivot'- ally connected to the forward end of a rod 39, the rear end Yof which. is guided `in an upstanding bracket 40 and is adapted for engagement by the upper forwardly extending nose 41 'of the operating lever 42 which latter is intermediately secured upon the operating shaft 34.

The upper end of each of the hammers 32- operates against the rear end of the respective firing pin 43 normally held in rearmost inoperative position by its controlling spring 44 and slidably mounted axially through its respective breech block 45.

Each of the breech blocks 45 is offset in 11o a vertical direction from the forward end of its respective plunger 4G to which it is fast, and preferably integral as shown in Fig. 2. The rear end of each of the said plungers 46, which passes through its respective guide recess 4T in a bracket 48 upstanding fromthe rear extension 26 of the gun frame 21, is connected by links 49 to an extension 50 of the operating shaft 34, it being noted from full lines in Fig. 2 that these parts 49 and 50 are longitudinally alined with one another when the plunger 4G is at its forward position to bring the breech block 45 in the firing position.

The lower portion of the breech 29 of each of the barrels 25, as indicated at 51, is hinged at its forward end at 52 to permit its rear end to swing downwardly and discharge the shells, and is controlled in its movement through a pair of links 53 and 54, the latter of which is secured to the before mentioned shaft 35, it being noted that, when the movable breech piece 51 is in its upper operative position, the links 53 and 54 are in longitudinal alinement. The shaft 35 has at one end a rigid arm 55 pivotally l connected by a rod 56 to the operating lever' 42.

Thus, in operation, the lower free end of the operating lever 42 is thrust forwardly after firing which simultaneously withdraws the several breech bolts 45, in the rearward movement of which the several hammers 32 are moved rearwardly until engaged by the spring controlled dogs 33 and held in their rearmost cocked positions as shown in Fig. 2. Also at the same time the several movable breech pieces 51 are moved downwardly, permitting the shells to fall out of the breech. 1When the several breech blocks 45 are withdrawn, fresh cartridges descend from the magazine or cartridge box 2T, and when the lower free end of the lever 42 is drawn rearwardly, these cartridges are thrust into the breech as the several breech pieces are closed. During this movement also the upper nose 41 of the lever 42 moves forwardly against the rea-r end of rod 39 and slightly rotates shaft 31 so as to withdraw the several dogs 33 and release the several hammers 32, each of which is provided further with a rearwardly projecting lug 57 engaged by a main spring 58 which, upon the release of the hammer, forces the same forwardly against the firing pin 43.

For swinging the entire gun frame 21 up and down upon its pivot 22 and horizontally upon the king bolt 18, a lever 59 is provided, pivotally connected at its upper end at GO to lower rearwardly projecting portions G1 of the said frame, said lever being provided with an intermediate recess 62 which normally receives one edge of the upper platform 15 of the tripod frame, to hold the frame 21 level, when the lever 59 is turned down and in vertical position, as shown in Figs. 1 and 2. At the extreme upper end of the lever 59 a sliding locking piece (33 having limited movement on the lever and engageable beneath a rigid inclined extension G4 of the gun frame 21 so as to lock the lever in raised position, as best seen in Fig. 3, `in connection with the gun frame 2.1 and thus enable convenient control of the movements of such frame.

From4 the foregoing it is obvious that the mechanisms of the several barrels 25 may be controlled as readily and expeditiously as one barrel and that, from the disclosure, the numbers of barrels may greatly vary dependent upon the particular uses for which the gun is designed, for instance, whether for offense or defense, and if for defense, whether the defensive works are of temporary or permanent nature, it being, of course, obvious that the less number of barrels there are to the gun, the lighter and more readily portable it becomes.
