.To all whom; it may concern.-

Be it known that LJEAN BAPrIsrE GUSTAVE ADOLIHE CANET G'DglIIGQQ a' citizen of the to ,theaccompanying drawings.--

This invention relates to firing mechanism forbreech-loading guns, and is more especially intended to be applied to quick-firing guns. It is well known that such guns are commonly fired by striking a fulminating or detonati'ng composition, it being usualto'act either directly or indirectly through a more or less rigid lanyard, which in practice is inconvenient. I

By my present invention I have overcome the objections which exist against the firingdevices heretofore in use and I have provided 1 4 mechanism whereby the firing hammer can be released with avery slight eifort on the partof the'guuner by means of a disengaging device which is so constructed that all the parts thereof return automatically to their original position after being released. In the accompanying drawings Wl1lCl1lllflS- tr'ate my invention, Figure'l is 'a longitudinal section showing one form of my improved releasing apparatus. Fig. 2 is a plan of a pertionof said apparatus hereinafter described Figs. 3,4 and 5 are transverse sections taken on the lines 3,3; 4:, 4; and 5, 5'respectively of Fig. 1. Fig. 6 is a horizontal central section of the breech end of a gun with the breechbloek in position, showing-the percussive firing device constructed according. to a mod i-- fication of my invention.

Bis the gun. t

O is a rod longitudinally niovable in beare parts .ings in the bracket A. -Thelrea r end-oflthe said rod 0 bears against the lever I) which controls the trigger of the percussive firing mechanism.

E is a sleeve surroundingthe rod 0 and pro- I vided on its exterior surface with alongitudiis a bracket seaforesaid rib a. v

The forwardend of the rod 0 is enlarged ich for a pure to form a collar or head I) wh pose hereinafter described can engage with a spring hook J fixed to the gun or to a part movable with the gun. The sleeve E is loose onthe rod'C and can turn thereon. It has formed at its forward end an eccentric collar 0' Figs. 2- and 3 the purpose of which is to press back the spring J and disengage the sarn'o from thecollar b of the rod 0 when the sleeveE is partially rotated as hereinafter described. The normal position of the one sided collar 0 is that shown in Fig. 3. The sleeve E is supported at its forward end in a claw L which is secured in the fixed bracket A, K is a pin fixed in the said claw L and which passes through a longitudinal slot' (1 rotation of the said rod when: the sleeve E is partially turned while allowing longitudinal movementof said rod. The said pin also at its rearend sufliciently wide to allow of the required-turning movementof the sleeve E and is of diminishing width from its rear to its forward end at which extremity it is .onlylof the same width as the pin K. One side of the said slot is made straight and parallel with the'axis of the sleeve, while the other side thereof as shown inFig. 2 is inclined as, and for a purpose, hereinafter described.

0 is'a ringsurrounding the rod (land inclosed in the sleeve E which ring is fixed by ,the pin K to the claw L. The said ringi constitntes an abutment for M which is inelosed in the sleeve E and the other end of which presses against a collar N fixed on the rod 0. The said spring is compressed when the rod (1 is pushed forward, and when released it serves to push the said rod back again. v

To place the device in a position ready 'for formed in the rod 0 thereby preventing the passesfhrough a longitudinal slote formed in the sleeve E. This latter slot however is one end of a spring use, the rod is pushed so far forward that the collar 2) engages with the hook J the said hook then retains the rod in this operative position wherein the lover D aforementioned bears against the rear extremity of the rod 0. If now the releasing lever G is depressed, which it may be by a slight pressure of the finger, the short arm thereof operates the bar F and causes the said bar which bears against the rib a of the sleeve E to partially rotate said sleeve whereupon the eccentrichead 0 of the said sleeve acts on the spring- J and disengages the same from the collarb of the rod 0 as shown in Figs 2. The latter rod now being released is immediately driven plained. Moreover during the recoil the hook J moves with the gun and again becomes engaged with the collar 1) of the rod 0. The forward face of the said collar is inclined as shown in Figs. 1 and 2 to permit the hook to slide past the collar during the recoil. iVhen the gun runs out again the hook remains in engagement with the collar b and thus'pulls the rod 0 and its sleeveE with it, and thereby compresses the spring M readyfor the next firing. The firing-leverD is also by the running out movement brought again in contact. or nearly so with the rod C. The parts are thus all restored to their initial position and are ready to be operated again to fire the gun-by the pressing of the lever G in the manner above described.

In the firing mechanism at the side of the gun illustrated in Fi 6 therod O is operated to effect the firing )y a spring M which is compressed between a collar N fixed on the rod and the end of the bracket A. The said spring is inclosed in'a tubular part A fixed to the said bracket A.. Near its forward end the rod C is provided with a slot 0 having oblique'ends C, C for a purpose hereinafter specified. The spring hook J which isfixed to the gun or to apart that recoils with the gun is adapted to enter the said slot and-thus become engaged with the rod O.- Whenso engaged with the rod the] curved face J of the hook bears against the end of a pinGr which is adapted to slide axiallyin abearing in the bracket A, and the head of which serves as the pointof application ofa lever G8 which is pivoted at G to'the' bracket A. The tail end of the lever G bears against and iscontrolled by the short arm of the releasing lever G. The operation of this mechanism is as follows: that is to say, by pressing the releasing lever G, the pin G? is pushed inward *so' as to force the hook J out of the slot 0 and clear of the rod 0 whereupon the spring M acts to drive the rodC backward and thus operates the firing lever D to fire the gun. I In' the rearward movement of the rod C'the. oblique face 0 of the rod 0 is brought in contact with an inclined part G of the pin G and operates to press the said pin outward again thereby replacing the levers G, G in their initial position. By the recoil movement of the gun after firing, the spring hook J moving with the gun is brought once more into a position wherein it can reenter the .slot C of the rod 0. Should the gun recoil beyond this position the curved end of thehook will slide over the oblique face 0 of the rod 0, returning over the said face when the gun again runs out so as to reenter the slot 0 and becomeengaged with" the rod 0. Thenthe continued runningout with it and will compress the spring M, thus restoring the parts to their initial position ready for the next firing operation.

The remaining parts .illustrated in Fig. 6 areas follows: E is the gun; B is the breechblock'; B is the carrier bracket which is hinged to the gun on a pivot or hinge pin B in the usual manner.

ing pin, the point B" of which can project I P is a tube screwed. concentrically into the breech-block. Q, Q .are two rings or plugs the first named of ,movement of the gun .will carry the rod 0 beyond the'face of the breech-screw; :Said

firingpin is controlled by a spring R which bearsagainst a collar 0" formed on the pin. Anotherv collar r formed on the pin forms a valve the'seat of which is constituted by the ring Q. Said valve operates to'prevent the access of powdergases to the breech-mechanism, in case any'should escape past the rear end of the cartridge. Behind the pin R is the firing hammer S-whieh is formed with whichis adapted to be screwed'on the end of the tube P. There is. also "a bush 8- which abuts against the said nut and thereare also mounted on the hammer a. spiral spring S .and a sleeve S the latter'beingretained by a pin S passing through the hammerbut so constructed as to allow the sleeveSta. certain hammer with respect tothesleeveS. When these parts are in, place, thenut-S? isscrewed on the tube P and-the sleeve-Sibearsagainst,

T is a spring which is compressed between a shoulder formed on the rod T and the bracket P, which spring operates to press the said rod in the rearward direction. The inner spherical end D of the firing-leverD previously re-' ferred to engages with a second slot T formed in the rod T and operates to slide. the said rod to and fro when the said lever D is oscillated about its pivot D The operation of this device-is as followsf, When the lever D is moved backward either by pulling-on a lanyard fastened in the eye of the said lever or by the operation of the red C abovedescribed, the rod T is thereby moved forward and caused to turn the lever, o and through the detent S draw back the hammer S and In this movement, the cam portion of the lever 0 describes an 'arc of a circle while the detent S moves in a straight line, and consequently at a cer-' tain part of the movement the detent escapes from the cam 0' and releases the hammer.

The latter thereupon is driven: forward by its spring until arrested bythe sleeve S com ing in contact with the aforesaid internal shoulder of the tube P. Byreason however of the inertia acquired by the hammer, and the fact that it can move through the sleeve ,S for a'short distance, the hammer continues its forward movement'so far as tovstrike and drive forward the firing pin and fire the gun. In so doing the hammer carries inward the bush 8 and operates to slightlyjcompress the spring S between thesaid bush and the sleeve St The hammer is then brought back to its initial position of rest by-its spring 3.

When the gun recoils, the lever'D is withdrawnffrom the red C and is then free to re 4 turn to its initial position whichit does under the pressureof the'spring'T and atthe same time turns back-the lever o andoaus'es the cam part 0 of saidgle'v'er to force back and then to re-engagewith the spftihg detent S. -Allthe parts of the firing-mechanism-are thus returned to theirinitial'position, ,To prevent fi ting before the breech-screw is properly screwed home, I so arrange that, the forward end;ofthe r'od'T shall be in close proximity to the rear end of the breech-screw and I provide a recess 8' in the breech-screw in such position that said recess is in line with the, rod T when and my when the The rod T can bev moved forward to fire the gun;

breech-screw isproperly screwed home.

when but not until the recess 'is'oppos'ite' the end'of the rod, that isto say, when-the breech is properly closed.
