Figs. 7 and 8 are views of a third embodiment of the invention shown respectively in inoperative and operative position,

Fig. 9 is a section along the line S--Q of Fig. 8.

Figs.' '.10 and 11 are views of another embodin parts ment `of. the invention withthc safety device respeotively in inoperative and operative position, Figs. 12 and 13 are similar views oi still another embodiment of the invention, l

Figs. .14 and 15 are views of another embodiment of the invention respectively in inoperative the block I Il is inserted into the gua-rd I2 from j one side thereof. The block may consist of plasl tic material, light metal, wood or any other material. Preferably the block i0 is provided on the side where the recess I6 is provided with a cover 20 which has two ` iiange parts 22 and 24. A screw 26 holds the cover 20 in positioncn-:the block I0. Between the cover 2B and thefront'sideof the block I0 is left a space in which-a-fcircular disc 2S is slidably arranged. Thecirculardisc or plate 28 is provided with a handle y30 which is slidably arranged in a horizontal slot 32 .provided in the front part of the cover 20.

The operation of the safety device is/as follows:

The block I0 with the plate 28 inits left-hand position according to Figs. v1 and 2 -is inserted into the guard I2 of the rifle whereby the trigger I8 is accommodated in the recess I6. lThenthe plate 23 is moved by pushing the lhandlell to the right so that it reaches the position shown in Fig. 4 in which the trigger I8 4`is.substantially covered from all sides. If hdesired the-,platel maybe secured in this positionby. a rlockinot shown).

The plate 28` need not be circularrinshape, nor is the sliding arrangement indispensable. lThe plate 28 for instance could be .provided with a recess having about a quarter of its area. and

vcould be turnably larranged vabout itscentre so as to cover the recess l5 in one-position -and to uncover the same in anctherposition.

In another-embodiment the-'plate'is hinged to the block I0 sol that in one position ittcovers the recess I6 and the trigger I8. Inthis case, Ithe cover 29 may be dispensed with.

r.he safety device may also be adapted to double barreled Shotguns comprising two triggers by increasing the widthof the block 2f!A and the recess I6.

Referring now to Figs. 5 vand 6,.l0-is apistol provided with-a trigger li2-and-a-guardf44- In order to protect the guard 44 andthe-trigger 42 a cover 46 is provided'which preferably'consists of sheet metal or vother'resilient material. The cover 56 comprises two portionsfand covering the guard 44 on both sides, and a'connectingsportion 52. The walls 45 and v50' are' provided with dents Fal which cooperate with similar dents'inl the guard 44 so as'to hold said cover in position on the guard. -If desired,- this-device maybe provided with means'for blocking the trigger, for instance with leaf springs which.. catch ther trigger from behind.

Referring-howto Figs. 7 9, I4 is a. stock ,ofra rie from which the guard I2` andthe trigger I8 `orotrude. The stock I4 is provided witha recess 6I) above the guard I2. A two-walled elementSZ whose shape in its lower part corresponds' toV that of the guard I2 is movableso thatin inoperative positionitris inside ofthe'firecess'as shown' in Fig. '7 whereas inoperative 'position "(Fig. f8) yit covers the trigger I8 on both sides thereof. The element 62 is provided with one or two flanges 64, which protrude at right angles to the walls of the element. These flanges 64 have a two-fold function. They serve as a handle for shifting the element in and out of operative position and secondly, they form stops by abutting against the rifle stock I4 in the uppermost position and against the guard I2 in the lowermost position of the element. 66 is a cross member such as a rivet or pin joiningr the two walls of the element 62 and locking the trigger I8 by abutting cooperation with same when the element is in its operative position. A bridge 68 joins the walls of the element 62 at their upper edges and is provided with a slot for the trigger and its associate mechanism.

The operation of the safety device shown in Figs. '7-9 is as follows:

In the position shown in Fig. 7 the element 62 is retracted within the recess 60 ofthe riiie stock |4. If it is intended to protect the trigger against accidental operation, the element 62 is brought into the position shown in Fig. 8 by pulling the flanges 64 downwardly until they abut against the guard I2. In this position the cross member 66 locks the trigger against accidental discharge of the weapon. If it is desired to use the ride again, the anges 64 are pushed upwardly until they abut against the rifle stock I4.

Referring now to Figs. l0 and 11, I4 is again the rifle stock, I2 the guard and I8 the trigger. A pocket-shaped cover 60 is pivoted at 82 to the guard. The pivot 82 is arranged at the corner of said cover 80 and at one end of the guard I2 preferably behind the trigger I8 so that the cover 80 may be swung into and out of the guard cover position. 84 are projections arranged at the corner of the pocket opposite to the pivot F12. They serve for an easy handling of the cover i. 88 is a pin or the like arranged in the cover 1&5. at an inclined position so that it comes into cooperative engagement with the lower end of the trigger I8 in the guard covering position oi the cover 80. The pin 88 is provided with a head S0 and secured to the rim 02 of the cover. 94 is an, opening in the guard I2 through which the pin 88 extends when the cover is brought into operative position.

The operation of this device is as follows:

If the rifle is to be used the cover 80 is swung to the back as shown in Fig. 10, the rie butt being provided with a suitable recess (not shown) for accommodating the cover B0. If it is intended to secure the rie against accidental discharge the cover 80 is brought into the position shown in Fig. 11 in which it covers the guard I2. In this position the pin 88 locks'the trigger I8 against operation.

Referring now to Figs. 12 and 13, I4 is again the rie stock, I2 the guard and I8 the trigger. The guard I2 is slotted over almost its entire length as shown at |02. Through this slot block |04 may be inserted from below. The block I 04 has a shape substantially corresponding to that of the guard, and is provided with a slot |00 for accommodating the trigger. Also the block |04 is recessed at |08 and I I0 near its upper corners for a purpose presently to be explained. I $2 is a strip made 'of resilient material such as 'metal which is secured by screws II4 and IIS to the block. The free ends of the strip are shaped as end pieces I I8 and |20 provided with catches I 22 and |24 cooperating with recesses |26 and |20 provided in the guard I2. |30 and |32 are knobs 4 for pressing the catches |22, |24 out or therecesses |26, |28.

The operation of this device is as follows:

When it is intended to insert the block |04 it is rst brought into the position shown in Fig. 12 in which the block |04 is directly underneath the guard I2 with its upper margin in the slot |02. The block |64 is then pushed upwards until the metal strip I |2 abuts with the slotted part |02 of the guard I2. In this position the free ends I I3, |20 enter with their catches |22, |24 the recesses |26, |28 of the guard I2 so that the block |04 is safely-secured in operative position. The trigger I3 enters the recess |06 of the block and as this recess has the minimum width corresponding to the trigger I8, it locks the trigger against a discharge of the weapon. If it is desired to remove the lock |04 from its operative position shown in Fig. 13 the knobs |30 and |32 are slightly pressed so that the catches |22 and |24 leave the recesses |26 and |28. The block |04 can then be withdrawn in a. downward direction.

Referring now to Figs. 1li-16, I4 is again a rifle stock, I2 the guard and I8 the trigger. Above the guard I2 the rifle stock is provided with a recess accommodating a two-walled element |40 which has substantially the same conguration as the opening of the guard I2. The two walls of the element |40 are joined by a cross member |42 which in operative position of the guard lies behind the trigger I8 so as to lock the same by its cooperative abutment with the trigger. The two walls of the element |40 are provided with extensions |534 which are pivoted at |46 to the rifle stock I4. A coil spring I48..is provided around the fulcrum |46 and has one arm |50 fixed to the stock I4 at |52 whereas the other arm |51! presses against the element |40 and urges the saine into operative position. |58 is a hole near the upper edge of one of said walls constituting the element UitI which in inoperative position or the element comes into engagement with a hook |60 which is secured to a leaf spring |62 or the like fixed with one end to the riiie stock I4. |64 is the other end of the leaf spring protruding through a hole in the rie stock I4 so that it can be pressed downwardly by hand thus releasing the hook |00 from the hold |58 so that the spring |48 brings the element |40 into operative position. A cross piece |66 arranged at the margin of the element |40 and knurled at its sides rests in inoperative position of the element in a recess |68 of the rifle stock.

The operation of this device is as follows:

In inoperative position shown in Fig. 14 the member |453 is in the recess inside the stock I4. In this position the hook |60 enters the hole |58 so that the element |40 is held against the force of the spring |40 which is in the state of compression. If it is desired to bring the element |40 into operative position shown in Fig. 15 the knurled end |66 of the leaf spring |62 is pressed into the rie stock so that the hook |60 leaves the opening |53. Then the spring |48 turns the element |40 around its fulcruin |45 until the member' |56 abuts against the guard I2. In this position the cross member |42 lies behind the trigger I8 so as to lock the same. If it is desired to return the element |40 into non-operative position shown in Fig. 14 it is turned in an anticlockwise direction by means of the member |05 until the latter abut-s against the recess |58 of the stock I4. Towards the end of this movement the hook |60 arranged on the leaf spring comes to engagement with the hole |58 whereby the hook |60 snaps into the hole |58 so that the element |40 is locked in inoperative position.

I have described preferred embodiments of my invention, but it is understood that this disclosure is for the purpose of illustration and that various omissions or changes in shape, proportion and arrangement of parts, as Well as the substitution of equivalent elements for those, herein shown and described, may be made Without departing 'from the spirit and scope of the invention as set forth in the appended claims.

What I claim is:

1. A rearm comprising: a trigger, a guard for said trigger, a v.block tting in said guard, said block being provided with a recess for accommodating said trigger, and a plate on said block movable between two end positions, said plate in one end position covering said recess.

2. A rearm comprising: a trigger, a guard for said trigger, a block tting in said guard, said blockbeing provided with a recess for arcommodating said trigger, and a sliding plate on said block movable between two end positions, said plate in one end position covering said recess.
