SAFETY DEVICE FOR PORTABLE FIREARMS.

Application filed February 10, 1921. Serial No. 448,989.

Tov all whom it may concern:

Be it known that I, EDWARD LARSON, .a subject of the King of Sweden, residing at Lerdala, Sweden, have invented certain new and useful Improvement in Safety Devices for Portable Firearms, of which the following is a specification.

The present. invention relates to safety devices for portable fire-arms of the kind in which members that normally lock the trigger, that is tosay prevent the discharging movement thereof, are automatically released on seizing the handle of the stock at firing.

To make a safety device satisfacto every point of view, it has to be simp e so as not to get out of order, and it must not be rendered unserviceable throu h wear and tear, but on the contrary it s ould always be fit for action as long as the gun is capable of use in other respects, and further it must be so devised that the hammer cannot be releasedby a shock to the gun, or by d'efects occurring in the sear spring thereof.

In my opinion the safety devices of this kind as hereto-fore known do not comply with these requirements, which on the other hands are in every respect met by the device forming the object of the present inso vention.

Moreover, by the invention the exceedingly important advantage is attained in guns with invisible hammers, that it may be seen at once from the position of the locking members if the hammer or the hammers are cocked, that is to say, if the shots have been fired.

Thus a gun with invisible hammers provided with a safety device according to the 40 present invention has the advantage of a gun with visible hammers, in that it can be seen at once whether a hammer is cooked or not, simultaneously as the disadvantage inherent in guns wlth visible hammers consisting in the hammers being easily acted upon by boughs and the like, is avoided. Furthermore, the advantage is attained, that the marksman, on having once charged the gun, can always see which shot has been discharged and. which has not. This, certainly, is not possible in guns with visible hammers, without the gun being opened.

An embodiment of the invention is illustrated in the accompanying drawing.

56 Fig. 1 shows the device in elevation, the

from

parts assuming the positions wherein hammer is under tension.

Fig. 2, likewise,is an elevation show the position of the parts after the discha1 Fig. 3 is a plan view of the device.

1 designates the trigger which is pivo to the stud 2. The hammer is denoted by and the sear by 14. This sear cooper: with two locking members which. are forr like levers, viz. an upper one'3, 4 and lower one 5, 6, the said levers being pii ally mounted on the same stud 7 in the ing of the gun lock. The lever 3, 4 is in form of a double-armed bell crank lever, outer arm 4 thereof projecting througl slot in the top of the handle of the st when the lever is in its locking posit (Fig. 1), whereas the other arm 3 of lever engages with its arch-shaped end 5 face 16 over the lateral abutment 8 at rear end of the sear 14. The lever 5, i also shaped like a bell crank lever and I jects with its one arm 6 through a slot the bottom of the handle of the stock, w] the inner arm 5 of the lever engages wit nose 9 over the abutment 8 at the rear 1 of the sear 14. The lever 3, 4 is actuated the spring 10, and the lever 5, 6 by the spr 11. These springs have a tendency to hr the said levers into locking position.

The sear is so arranged that the rear 1 thereof assumes a lower position (Fig. when the hammer is cocked, and a hlg position when the hammer is uncooked.

The action of the device is as follows:

Referring to Fig. 1, which shows the p tion of the parts when the hammer cocked, both levers 3, 4 and 5, 6 are actua when seizing the handle of the stock firing, in that their outer arms 4 and 6 spectively are pressed inwardly through pressure of the hand thereagainst. inner arm 3 of the upper lever is then SW1 forward, so that the abutment 8 of the s looses the support of the curved end suri 16 of the said arm, and the lower love] swung rearward, so that the nose 9 ther is brought out of engagement with the at ment 8.

Thus the sear is no longer locked by levers, but the shot may be discharged pulling the trigger in known manner.

On the hammer being uncooked at the 1 charge of the shot the rear end of the s is brought upwards, the abutment 8 of then coming in contact with the rear 2 12 of the arm 3, and also in contact I the part 16 of the fore edge of the r 5 above the nose 9. Thus the two levers retained in the position into which they 2 brought on the release, and in which r outer arms are pressed into the stock, hat it may be seen at once that the hamis uncooked and the shot discharged.

n recocking the hammer the sear is lght back again to its lower position, and lockin members (the levers) again ase the locking position under the action xheir springs, the said members in this tion indicating that the hammer is red. The upper lever must be shaped arranged so that the two arms thereof approximately of the same weight.

n double-barrel guns which, as is known, e the widest use, there is arranged for 1 hammer and sear pertaining thereto, upper as well as a lower locking sear, t is to say four levers in all. The two )ermost levers are arranged side by side acent to each other, and, likewise, the lowermost levers are arranged in the aner indicated in Fig. 3.

Vhat I claim as new and desire to secure Letters Patent of the United States is A. safety device for guns, including a me, a hammer, means for holding the nmer in the cocking position, a trigger, members for locking said trigger indeidently of each other, said locking mems each having a part projecting outside the handle of the stock so that the lockmembers are released on seizing the ck at firing, and means for causing said king members to be locked automatically the released position after the discharge. 5. A safety device for guns including a me, a hammer, a sear, a member locking d sear, means for releasing said locking mber on seizing the stock at firing, and ans for causing said locking member to looked after the discharge automatically the released position, and means for rening the locking member automatically the locking position on recocking the nmer. i.
