To 11/] llll/lllll/ if nut concern.-

Be it known that we. Flt-m7. Nnnnnu, residing at Wionor-Noustadt.and .h isnru 'lAMnoUR, residingatVienna, in the Province of Lower Austria, in the Empire of Austria-1lungary, subjects of tho l hnpol'or of Austria-llungary, have invented certain nou'and useful Improvements in Small-Arms; and we do hereby declare the following to be a full, clear, and exact description o' the. invention, such as will enable others skilled in the art to which-it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this spocilicatitm.

This invention has relation to that type of halal-firearms in which the hammer is held in position for liring by a bar-shaped sear. \Yith a view to facilitate the disengagement of the sear from the tumbler or hannnor and for the purpose of safely holding said hammer in its position for liring it has been the practice heretofore, in the type of lirearms roferrod to, to form in the tumbler or hammer an acute-angled notch, so that the end of the bar soar engaging said notch had to be in the form of a knife-edge, or su bstantially so. This construction has tho. disadvantage that if the gun is subjected to concussion, as is liable to be tho case, the sear is liable to spring out'of the aforesaid notch or break, causing the unintentional discharge of the gun.

This invention has for its object a construction of gun-lock whereby the recited disadvantage is avoided by providing the tumbler or hammer with a notch of such angular form and having its straight face in such radial relation relatively to the axis of rotation of said tumbler or hammer as to admit of the use of a bar soar of sufiiciont strength to prevent its breaking under practically any strain and the v i i l notch should the gun be subjected to concus- 1 sion or under the stress of the haminor-spring. ()ur invention has for its further ()bJOOi, the combination, with the liring mechanism, of

cidontally released when tho hammer is in its firing position by inadvertent or accidental pressure on the trigger, said means being so organized that the trigger cannot be pulled to lire the gun unless tho stock is grasped in the usual manner to bring the gun to firing plied toa double-l )arrel breech-loading lirearm of the so-callo'd hammorless type i. of that t-y pc in which the hannners are concealed. Fig. 2 is a similar view showing our improvements applied to'an ordinary doulde-barrel breech-loading gun also showing a modified construction of auxiliary safety appliances. Fig. 2' is a fragmentary sectional pla. view, and Fig. 4- a fragmentary longitudinal section, of the auxiliary safety appliance shown in Fig. i. Fig. 5 is a fragmentary under side view, and Fig. 6 a fragmentary longitudinal section, of the modilied auxiliary appliance shown in Fig. 2.

Referring to Fig. 1, the hammers I) are cocked in the usual manner by the lover or levers a when the barrels are turned down for the introduction of the load, and, as shown, said hammers have an obtuse-angled or practically a right-angled notch (1, each hammer being actuated by a spring 1 Owing to the (.lescribed conformation of the notch a, the

. straight face of which has such radial relation provision of means for preventing the accidental disengagement of the sear from said relatively to the axis of rotation of the hammer as to lie in a substantially vertical plane when said hammer is in firing'position, we are enabled to make use of a bar sear having a mmparatively thick and a correspondinglybeveled end for engagement with the aforemeans whereby said mechanism cannot be ac- 1 in theform of a two-armed straight or bar lein said Fig. 1.

ver having arms of unequal length and is fulcrumed at f, a spring e exerting suflieient power on the longer arm to depress the same, and crmsequently elevate its shorter arm when the latter i not in engagement with the hammer-notch u-----that is to say, when the hammer is in its position after firing-in which case the heel of said hammer rests upon the nose or end of the scar and holds its shorter arm down u nder tl 19 greater stress of the hammer-spring. Vhen, however, the barrels are swung down, the hammer is turned back on its pivot, its heel clearing the end or nose of sear g, and thus enabling the spring/. to depress the longer arm of said sear and move the end of its shorter arm against the then substantially vertical face of the hammer-notch a, as shown To prevent the accidental release of'the hammer from any cause, we provide a right-angled or elbow locking-lever h, the vertical short arm of which is-fulcrumed at 7', and in .the forward vertical face of said lever is formed a right-angled notch or to engage the rear end of the longer arm of the 'Isear g and hold the latter in engagement with the hammer-notch a against the stress of the hammer spring w. On the fulcrum-pin i, which is rigidly connected to the lock-frame, is secured an abutment h, on the under face of which bears the free end of a spring l, whose opposite end is secured. to said lever near its rear end, said spring tending to turn the lever on its fulcrum from left to right, and thus hold itsnotch n in the path of the end of the longer arm of the sear 1 and prevent the latter from being tilted in the same direction out of engagement with the hammer-notch u, the rotation of the lever it in an opposite direction being limited by the trigger-guard strap 1! of the gun-lock. This lever may be actuated by anordinary trigger in such a manner that when said trigger is pulled back an arm thereof impinging upon the longer horizontal arm of said lever /1 will tilt the same to the right, and thus move its notch clear of the end of the longer arm of the. sear g and allow the hannnr i --spring w to throw the hammer 7/ forward. in the gun shown in Fig. 1 we substitute the well-known push-pin or pin-trigger o for the usual trigger, the inner end 0 of which pin acts on the i arwardly-inclined face f a notch in the under side of the lock-lever It. By means of the lever l/. the sear is securely held in engagement with the hammer and can therefore not be disengaged therefrom otherwise than by a manipulation of the trigger.

In Fig. .2 we have shown ourimprovements appliedth a double-bm'rel breech-loading gun having exposed hammers J. 1 hand-cocked hammers and in this case the sear-notch above referred to is formed in the tumbler 0, the scar being constructed in the form of an angle-lever to suit the altered conditions of gun lock. 1' indicating the spring which acts on the longer arm of said sear, and f the pivot for the latter. The locking device here employed is a slide-bar l', sliding on a pin j, which extends through'a longitudinal slot in said bar, which has the, lock-notch 1/ formed in its forward vertical face for engagement with the rear end of the longer arm of the sear g. The bar Z- is under the stress of a spring in, which tends to push the bar forwardly, and thus holds the same in engagement with the sear so long as the hammer is in its firing position. The bar is retracted against the stress of its spring 111, and thereby moved out of engagement with the scary by an angle-lever r1, one arm of which has hearing on pin 7), projecting laterally from said arm, while the inner end o of the pin-trigger o impinges or is adapted-to impinge upon the other arm of said angle-lever, as clearly shown. In said Fig. 2, 10 indicates the main or hammer spring, connected in a well-known manner with the tumbler c.

The described arrangement of scar and locking-lever has the advantage over similar appliances heretofore proposed, in that by .the alinement and relative arrangement of the lock-lever and sear the former sustains but a very small proportion of the pressure exerted by-the hammer-spring instead of sustaining the whole pressure of said spring, so that but a very slight pressure on the long arm of said lever will disengage it from the sear.

It will be seen that with agun-lock organized described in referenceto Figs. 1 and 2 an accidental release of the hammers by reason of shock or concussion cannot take place; but the construction would not prevent such a release by inadvertent pressure on a trigger, as may be the ease in careless handling of the gun. To guard against a premature discharge of the gun by reason of such careless handling or inadvertent pressure on'the trigger-pins, we provide a safety device so organized that the release of the hammer cannot take place unless the gun is grasped in the usual manner to bring it into position for firing, whereby the said safety device is thrown or moved out of operative position, so that the gun can be fired by pressure upon the trigger.

in Figs. 1 and 2 we have. shown a lever 11 fulcrumed at its rear end to the trigger-guard strap v and having at its forward end a vortical extension from which projects laterally a pin or stud a, bcaring against the rear-shorter arm of a two-armed lever r, fulcrumed at s, the longer arm of said lcver impinging on or bearing against the rear end face of the lockingle\ 'er 1, Fig. l, or the locking-bar 1-, Fig. 2, and If is a spring connected to the triggerguar'd strap at one. end and having its opposite end so connected to said short arm of the safety-lever was to hold the longer arm thoroof substantially in alinement with said locking-lever or bar A'. ,'lhe rclcaslrig-lover u LII projects sufficiently from the trigger-guard I strap e, so that when the gun-stock is grasped in rear of the trigger-guard the pin H at the forward end of the releasing-lever'u will tilt the safety-lever r to the right out of engagement with the locking-lever /1 or har k. and thus admitof said'lever or har heing operated hy the trigger to disengage the sear from the hannner.

in practice we prefer to provide an additional safeguard in the form of a locking device arranged to lock the safet \'-le\'ei' i/ against motion under pressure of the hand. said locking device heing so arranged that its disengagement from the lever can readily he effected h v sliding the handalong the gun-stock toward the harrel. for instance. in the act of raising the gun to or after it has heen raised to the shoulder for tiring.

In Figs. 1 and 2 we have shown a-suitahle guard for the pin-triggers u and a suitahle guard w for the lever H. in Figs. .2. f), and

t3 the latch t constitutes the forward portion of said guard 1 and is pivoted to the latter.-

The end of the latch portion 1'' of the guard ex is recurvedand is held in normal engagement with a notch or recess in the forward vertical face of lever r/ in a spring .1. secured to the lived guard portion 1 and extending along a recess in the latch portion 1-. This latch 1 may he duplicated, as shown in Figs. 1,3. and 4. one on each side of the guard w", and adapted to ei'igage snitahle notches or recesses in the opposite sides of lever 11. so that should one of said latcheshecome accidentally disengaged from said lever u from any cause the other will still hold said lever against motion until the other latch is also disengaged from said lever, hoth latches heing simultanel I ously moved out of engagement with the lever h v sliding the hand along the gun-stock. as ahove explained. The latch or latches 1" may have fiat faces formed at their pivoted end, Fig. 4. against which hears th'espring .1, soas to hold said latch more lirml in locking and disengaged positions, requiring some force to move such latch from one position into the other. Should the gun he raised and made ready for firing and not tired. the lever 1/ is to he relievet of pressure, in the arrangement shown in Figs. 2. 5. and t), hefore the hand is withdrawn from the guard I'X to release the latch or latches w. therehy enahling the springf to depress said lever into position to heengaged h v said latch or latches when the hand is withdrie n from said guard. A jamming of the parts is thus rendered impossihie; especiall in iew of the fact that the spring I is more powerful than the latcli-aetuating spring. Figs. 2,5. a..d (3. In the construction shown in l igs. l, 3. andt the hand may he withdrawn from the guard w", hecause the spring .i'holds the latch in itsdisengageil position, so that it does not snap toward said lever when relieved of the pressure. hut must he forcihlv thrown into engagement with said lever against the. stress of the spring exerted-on one of the faces 1'.
