6 Claims. (o1.-42-7o) f This invention relates to and has for a primary object the provision of a trigger lock, adaptable for use, with but slight modifications, on rifles and pistols, and serving to provide a safety attachment for preventing accidental firing of the un An object is to provide a trigger lock, separate from, but readily attachable to, the trigger and trigger guard, and which is key operated for locking the attachment on and unlocking it from operative position on the gun.

Another object is to provide a lock applicable to a trigger and its guard, which is freely adjustable to and from locking position, in order that it may be used on guns of different make and dimensions. Other objects will be revealed after consideration of the hereinafter following description of our improvements. f

4 We have shown a preferred form of trigger lock, embodying our improvements, in the accompanying drawings with minor modifications, in which:

' Fig. 1 is a partial side view of a rifle, to which one form of lock is applied; {f n Fig. 2 is a section of the same on line 2-2;

Fig. 3 is an enlarged fragmentary and sectional view on line 3-3 of Fig. 2;

Fig. 4 is a sectional view on line 4-4 of Fig. 3;

Fig. 5 is a partial side view of the lock body, as viewed in the direction of arrow of Fig. 4; i Fig. 6 is a, fragmentary side view of a pistol, with a modified form of lock, applied to the guard and trigger thereof;

Fig. 7 is a side view of the lock of Fig. 6;

Fig. 8 is a cross section on line .8-8 of Fig. 'l; and :1 2;.

Fig. 9 is a fragmentary view of the lock body as seen looking in the direction of arrow}! in Fig. 7.

The lock disclosed in Figs. 1 to 5; inclusive, has a hollow body or housing I of substantially cubical form in which a spring 2 is anchored at 3 so that its tensioned free end! engages with a ratchet bar 5, which is slidable] through openings in opposite sides 6 and 1 of body I and affording bearings for the bar, as shown'in Fig. 3, the bar passing to one side of the, trigger as will be evident from Fig. 2. Rifles, and also pistols and revolvers as at B. have dependingguards G which surround and protect a -,trigger; T. Our lock is provided with a bifurcated extension 8 on a side of body I, between the furcations of which the trigger T may be confined and held in rearward position, as shown in Fig. i, for-preventing the forward movement of the trigger, into cockins position when a bifurcated portion 9 of ratchet bar 5 is engaged against the inside of the forward end of guard G, as shown in Figs. 1 and 2.

i As illustrated in Fig. 3, when the lock is operatively positioned, the end 4 of spring 2 will prevent the retraction of bar 5 to the right until said'spring is released from the bar as by means of a suitable key III, which may be extended through key slots I I (Fig. 5) in opposite sides of body I and formed with a ward I2, adapted to bear against and move said spring out of engagement with the notches in:bar 5, so that the bar may be retracted to a disengaged position relative to guard G, and body I then disengaged from trigger T. Key I0 is only employed for unlocking the unit, inasmuch as the bar 5 will be self looking when it is positioned in the body and extended into engagement with the guard and portion 8 of the body is engaged with trigger T.

, The modified form of device shown in Figs. 6

to 9, inclusive, is different from that shown in Figs. 1 through 5 principally in that it is arranged to lock the trigger T of a pistol in a forward position, to such end, the body Ia of the lock has an extension I3, with a right angular portion I4, through which and opposite walls of body Ia, a ratchet bar 5a projects; Bar So has a hooked end portion I5, which is engageable with guard Gf while extension I3-I4 engages trigger T.

v Thus, when bar 5a is tightened and locked'bya spring similar to spring 2 in body I, the trigger I" is held in forward position as shown in Fig. 6, and may not be operated until it is unlocked by a suitable key, as in the first described form of device. q

; We claim:

1. A trigger lock for firearms including: a small housing adapted to be positioned within the trigger guard between the front of the trigger and the forward end of the guard; a stationary engaging member carried by said housing, a movable engaging member mounted for longitudinal movement through said housing freely in one direction: means mounted within said housing normally effective to prevent movement of said movable member in the opposite direction until released, the construction being such that when the lock is positioned in the trigger guard with the engaging members engaged with the trigger and trigger guard with the movable engaging member moved as far as possible in the housing the trigger is securely held against movement; and releasing means operable to render ineffective said means normally efi'ective to prevent movement of the movable engaging memher and enabling said member to be moved to free said lock.

2. A trigger lock for firearms including: a. small housing adapted to be positioned within the trigger guard between the front of the trigger and the forward end of the guard; a stationary engaging member carried by said housing; a movable engaging member mounted for longitudinal movement through said' housing freely in one direction; said member having an' elongated serrated stem passing through openings in opposite sides of the housing nd acting as bear-' ings for the stem; a member mounted imsaid. housing and resiliently engaging in said serrations to prevent movement of thestem-inone direction while sliding over said'serrations when the stem is moved in the opposite direction, the.

construction being such that when the lock is positioned in the trigger guard with the engag ing members engaged with the trigger and trigger guard with: themovable engaging; member moved as :far. as. possible :in the housing; the trigger'sissecurely helda;against-movement and -.-releasingimeanszoperable torender ineifective said.
