SAFETY ATTACHMENT FOR FIREARMS.

Application filed June 10, 1925.

To all whom it may concern:

Be it known that we, FRED E. LEWIS and THOMAS J. WVILLIAMs, citizens of the United States, residing at the city of Utica, in the county of Oneida and State of New York, have invented certain new and useful Tmprovements in Safety Attachments for Firearms, of which the following is a specification, reference being had therein to the accompanying drawing.

Our invention relates to a safety attachment for firearms, and we declare the following to be a full, clear, concise and exact description thereof sufficient to enable anyone skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings in which like reference characters refer to like parts throughout the specification.

The object of the invention is to provide a device that can be readily attached to any firearm in such manner as to prevent the accidental release of the trigger, when the firearm is cooked, and yet, permit the user to release the trigger manually when shoot- Furthermore, the device is designed to make possible a quicker firing of the gun than heretofore, as was the case with the trigger and, also to lessen the danger of any accidental discharge of the firearm. Moreover, it will enable the user to wear gloves or other covering without interfering with the accuracy of aiming and discharging the gun. This feature will be found useful particularly in cold weather when gloves are necessary.

The object will be understood by referring to the drawings, in which:

Fig. 1 is a fragmentary view of firearm showing the device attached thereto;

Fig. 2 is a central vertical section taken on the line 2, 2 of Figure 1;

Fig. 3 is a detail perspective view of a part of the atachment;

Fig. 4 is a detail perspective view of a member employed;

Fig. 5 is a detail perspective view of a latch employed showing a part thereof separated therefrom and about faced;

Fig. 6 is a detail perspective view of another memb r empl yed;

Serial No. 36,251.

Fig. 7 is a perspective detail view of a plate and immediate parts used;

Fig. 8 is a detail perspective view of a lu used.

lteferring more particularly to the drawings, an ordinary firearm is represented by 1 having a trigger 2 and trigger guard 3, which parts are old and well known in the art.

The parts that are new embody a member 5 made preferably of metal and having a recess 6 conforming in shape to that of the trigger guard 3 which is housed therein, when the device is attached to the firearm. A laterally projecting lug 7 is mounted to member 5 adjacent wall 8 of recess 6 by screw bolts 8', 8 engaging threaded apertures in lug 7. Lug 7 is adapted to project through trigger guard 3, when assembled, so that there is provided space all about lug 7 for the disposition of said guard 3. An aperture 10 is made transversely through lug 7 for the projection of headed bolt 11, that is screw mounted to wall 8 of member 5, whereby to attach removable plate 12 to member 5 to close recess 6. Shoulders 9, 9 are formed integral with the inner surface of plate 12 and are adapted to engage the upper surface of the adjacent part of trigger guard 3, whereby to hold plate 12 rigidly in place when assembled to member 5 by bolt 11. Furthermore, wall 8 of member 5 is recessed at 15 for mounting rock arm 16 that is pivoted on a stud 17 formed integral with wall 8. The lower end of rock arm 16 carries a horizontally disposed plate 18 adapted to cover normally a recess 20 located in the under surface of member 5. Plate 18 is held against shoulder 21 formed in member 5 and in closed position to cover recess 20 by a coiled spring 22 disposed in an annular recess 23 formed in the solid part 24 of member 5 and attached at one end to a hook 25 formed integral with part 24 and at the other to rock arm 16. A hole 26 is made in arm 16 for attaching the end of said spring 22.

Moreover, plate 18 is locked in closed position by spring pressed latch member 30. Latch member 30 moves in a vertical plane in. recess 27 made in solid part 24 of mem her 5 and screw mounted to plunger 28 held normally in lower position by a coiled spring 26 housed thereabove in an annu-- larly formed recess and engaging the up standing shank 31 of plunger 28. Plunger 28 has also an annular headed part 32 below shank 31, on the under side of which headed part 32 is formed a ridge 33 adapted to be engaged by the finger of the operator, when shooting. A. small unbroken space 34 of member separates ridge 33 of plunger 28 from plate 18. Latch is adapted to engage a correspondingly formedor open position. Immediately the finger has passed over ridge 33 of head 32 and plate 18 been moved to the rear, latch member;30 will fly ba-ekunder pressure of coiled spring 26 to engage'reccss 35 in plate 18 when it returns to'closed position.

The means for engaging trigger 2 embodies a plate'4O resting above plate 18 and having an arm 41 formedintegral with one edge thereof "and provided with'an ofltset at 42 to allow for clearance of trigger guard 3. Arm 41 is housed inrecess 43 made in lug 7. 'Said recess being enlarged at 44 for offset portion 42.". Aishoulderis made at 45 in arm 41 foriholjding one end ofa coiled spring 46 disposedfab'outthe'upper end 47 of arm 41 and resting in recess 4'2. Recess 44 is re 'duced at 48 to form a shoulder to hold the end of spring46. Spring 46, will urge normally plate 40 to lower position. A proje'ctor 46; formed 011 plate 40 and adapted to engage a guide recess having a shoulder 49, is intended to limit the lowermost position of plate :40.

Arm 41 projects beyond lug 7 and is adapted to engage or he veryclose to trigger 2, whereby any upward movement of plate 40 will be communicated to trigger 2 through arm 41 and, thereby, move said trigger 2 to releasing position.

It'will be observed thatthe lower surface of part 50 of member 5 projects a little below the plane of head 32 and ridge 33 of latch 30, whereby to protect said parts from being disturbed accidentally.

'The operation ofthe deviceis effected by attachingtlie partsto a firearm, which can be done by applying member 5 with lug 7 projecting throughtrigger guard 3 and fastening plate 12 in place by projecting bolt 11 through lug 7 and screwing it into wall8 of member 5. this position the free end of arm 41 will beadjacent trigger 2 and be in position to releasesaid trigger 2 to discharge the firearm when actuated at the will of the user, Herder to actuate said arm 41, the

user will hold the gun in firing position and draw his finger across ridge 33 of head 32 of plunger 28, thereby elevating said plunger 28 and latch 30 connected thereto within their respective sockets, whereby to release latch 30 from engaging recess 35 in plate 18 at the same time the finger must begin to move plate 18 toward the rear. As plate 18 moves toward the rear, it will uncover plate 40 which will be engaged also by the same finger that actuates plate 18.

The movement of plate '40 will cause arm 41 to move trigger 2 to releasing position to discharge the firearm; i

It will be observed thatthe actuation of the partsifor discharging the firearm does not differ in manner of manipulation from the oldmethod and yet, has the additional security' ot preventing the accidental dis charge of the firearm. Both the latch 30 and plate 18 mu'st be moved simultaneously for such discharge; The movement of latch 30 without the movement of plate 18 will not permit the firearm to discharge. Furthermore, plate 18 cannot bemovedunless latch 30 is pressed against spring 26. '7

The attachment hereinabove described can be made asan integral part of the gun if desired.

Having thus describedour invention what we claim'as new and desire to secure by Letters Patent is:
