1 Claim.

The invention relates ,to a safety device for firearms and more especially to a safety trigger lock.

The primary object of the invention is the provision of a device of this character, wherein the ing thereoffiis rearwardly of the trigger of a'fire arm and fitted in the guard for said trigger so as to bein a convenient position for the manipula tion ofsuoh device, the device being susceptible A of travel or movement to a latching position with relation to the trigger so as'to prevent movement thereof when the firing pin of the firearmis in firing position, the device being o novel form and readily and conveniently operated by the hand of the user of the firearm.

V A further object of the invention is the provision of a device of this character, wherein by reason ofits construction the same is: handy,

easily operated and safe, the device being particularly adaptable for firearms of bolt-action type.

A still further object of the invention is the provision of a device of this character, which is extremely simplein construction, thoroughly reliable and efficient in 'its purpose, readily and easily operated withdispatch, strong, durable, and

inexpensive to manufacture and install.

. With these and other objects in View, the invention consists in the features of construction, com H bination and arrangement of parts as will be hereinafter more fully described in. detail, illustratedin the accompanyingdrawing, which discloses the preferred embodiment of the invention, and pointed out in theclaim hereunto appended,

1 In the accompanying drawing: a

Figure 1 is a fragmentary side elevation'of a firearm, the same being partly in section to show the trigger, the sear and the firing bolt or breech pin, with the device constructed in accordance with the invention applied, the breech pin or firing bolt being shown cooked or in firing position.

Figure 2 is a fragmentary side elevation of the Figure 5 is a sectional view on the line 55 of Figure 1 looking in the direction of the arrows.

Figure 6 is a perspective View of the firing bolt wedge.

Figure I is a perspectiveview of a. keeper block' for the trigger.

Figure 8 is a perspective view partly in sectio of the latch receiving barrel of the device.

' Similar reference characters indicate corresponding parts throughout the several views in the drawing.

Referring to the drawing in detail, A designates generally a portion of a firearm having the barrel iii and stock M, respectively. The firearmfin this instance, is of the bolt-action type and the bolt i2 is located at the breech end of the barrel iii and is cocked by'pulling upon a handle i3, so that this bolt will be engaged by the sear i4 pivoted at E5 in the stock H. The scar H! is urged into locking position through the medium i of a spring i6. Pivotally connected with the sear is a trigger ll, the finger-engaging end 88 being within a guard 19 bolted or otherwise fastened at iii to the said stock I I. The trigger H is pivoted at 2| to the sear, and on pulling upon the trigger I! at its finger end E8 the sear l4 will be lowered and disengaged from the bolt l2 so that the latter will instantly act for the firing operation ofthe firearm.

Suitably fitted in the stock H rearwardly of the trigger I! is a barrel 22 closed at its top and open at its bottom. Slidably fitted transversely inthe guard l9 immediately below the barrel 22 is a sliding pin 23 having a finger abutment 2 5, the bolt'being formed with keeper notches 25 and 26, respectively, these alternately receiving a retaining or latching ball 27, the same operated upon by a follower 28 sustained under tension by j a coiled expansion spring 23, the latter and the follower being within the barrel 22. Thus when the ball engages either of the keeper notches 25 and 26 the pin 23 will be frictionally held in its shouldertZ for abutment by the trigger I? when the pin 23 has been shifted to a position of safety f 'r preventing the finger actuation of the trigger H at the finger-engaging end it thereof. r

The trigger i! has formed thereon a block 33 for overhanging the bit 30 of the pin 23 so that when the latter has been thrown to safety this bit will engage beneath the block 33 with the trigger I! abutting the shou1der'32 providedby the against movement.

The bolt l2 at its underside next to the handle [3 has fitted therewith a wedge 34 so that when the bolt has been thrown to a firing position this wedge 34 will ride onto the sear Mand thus prevent the pin 23 from being moved to safety until the said bolt has been pulled outwardly to cocking position. The ball 21, by alternate engagement in the notches 25 and 26, will frictionally hold the pin 23 in either safety-on or safety-off positions. The safety-on position of the pin 23 can only be attained when the bolt 12 has been cocked by the sear Hi. The bolt 52, as is customary, is

fitted in the breech end of the barrel ID of the firearm and is manually cocked.

It is understood, of course, that the bolt I2 at the handle end thereof carries a firing pin or hammer 35, as is usual; I

What is claimed is:

notch in said bit and thus be latched or locked Ina firearm, a. stock, a barrel on the stock, a sear pivotally mounted in the stock, a firing bolt slidable with relation to the barrel and engaged to the trigger, a wedge on the firing bolt and cooperating with the sear and a block on the trigger and cooperative with the wedge to prevent the latch being moved to safety unless the firing bolt is fully cocked.
