May 1, 1962 R. SWAN FINGER REST ATTACHMENT FOR FIREARMS Filed Feb. 24, 1959 INVENTOR. QQBEQT SWAN ATTOQHEVS United States Patent it. I .0s1,;1s6. 1.. FINGER FOR Robert Swan, '4978 wawun'a St, L'o's Angeles, Calif. Filed Feb. 24, 1959, Ser. No. 795,029 2 Claims. (Cl. 42*1) This invention has to do generally "with firearms and more .particularly with an attachment for the trigger .guard of "airifle o'r'hand gu'n adaptetl'to provide support for'the end of 'the trigger 'finger adjacent the trigger.

In "the shooting "of-firearms it is generally accepted among experts that, once the sights have been aligned on the target, accuracy is dependent to a large extent upon the individual gradually squeezing the trigger of the gun rather than suddenly pulling or jerking it. A major difficulty with attempting to gradually squeeze the trigger of a gun is the fact that the trigger finger is unsupported. Due to the structure and shape of the human finger and the design of firearms with trigger guards, and triggers wherein the trigger path is parallel to the adjacent outer sides of the weapon, when the trigger finger is applied unsupported to the trigger, the finger motion has a tendency to pull the trigger to one side creating friction between the trigger and the gun frame which, to some extent causes the trigger to bind resulting in what is referred to by some as flinching on the part of the shooter. It is therefore an object of the invention to provide novel means for supporting the end of the trigger finger in a position laterally adjacent the trigger.

This support, by fixing the finger tip against move-' ment, changes the fulcrum point and allows the shooter to gradually pull straight back on the trigger, eliminating any trigger friction or binding and eliminating so-called fiinching.

A further object is to provide a novel finger rest in the nature of an attachment for a gun which can be readily mounted on the trigger guard thereof to provide a support or rest laterally adjacent the trigger.

Another object is to provide a novel attachment of the type indicated embodying a clamp which can be adjustably secured at a desired region along the trigger guard and embodying a novel finger support or rest which is adjustable relative to the clamp for the purpose of positioning the support at the desired location to suit both the individual and the particular firearm.

A further object is to provide a finger rest attachment of the type indicated which is so constructed and arranged that hand guns, including revolvers, pistols and automatics, to which it is applied can be carried in holsters presently in use including clam shell and speed holsters.

Still another object is to provide a novel finger rest attachment for the trigger guard of a firearm which is so constructed that it may be adjusted for use by either a rightor left-handed person.

These and other objects will be apparent from the drawing and the following description. Referring to the drawing:

FIG. 1 is a fragmentary side elevational view of one side of a revolver showing a finger rest attachment embodying the invention mounted on the trigger guard;

FIG. 2 is an elevational view of a portion of the other side of the revolver and finger rest attachment;

FIG. 3 is a sectional view on line 3-3 of FIG. 1;

FIG. 4 is a sectional view on line 44 of FIG. 5;

FIG. 5 is a sectional view on line 5-5 of FIG. 2; and

FIG. 6 is a perspective view of the finger rest.

More particularly describing the invention, numeral 11 generally designates a revolver and this is provided with the usual trigger guard 12 and trigger 14. Numeral 15 generally designates the finger rest attachment of the invention which is shown mounted upon the trigger guard 12 of the revolver.

*orc'hannel 28 for receiving the trigger guard '12 and in this connection the two -rne'mber's 20a'nd '21 'are disposed with their channels or grooves 28 in facingrelation and thus adapted -to engage opposite ed es 'of the trigger guard. Also, if desired, the channels may be somewhat curved, as best shown in FIG. 6, to more clearly approximate the configuration of the portion of the trigger guard to which they could be attached.

The two elements 20 and 21 of the clamp are held together by screws 30 which are freely received in bores 31 of member 20 and mounted in threaded bores 32 in member 21. It will be apparent that with this construction the two members of the clamp may be firmly secured to the trigger guard at any desired point therealong.

The finger support 18 includes an elongated base portion 35 having a slot 36 which receives a mounting screw 37, the inner end portion of which is received in a threaded bore 38 in member 21. The sides of the base portion 35 of the member 18 are preferably flat so that either one thereof may be placed adjacent the outer flat side 32 of member 21, thereby adapting the finger support for either right or left-handed use.

Extending upwardly from the base and slightly rearwardly inclined is an upper finger rest portion 40 of the support which provides a flat, forward facing fingersupporting face 41 which is preferably somewhat wider than the base portion 35. The sides and rear of the upper portion 40 of the finger support are rounded and converge at the upper end to provide a somewhat bluntpointed upper end portion 42. The angle of the face 41 with respect to the longitudinal axis of the base is preferably within the range of to 130 and, in the device shown, is about In use, the attachment 15 is first applied to the trigger guard 12 by securing the clamp 16 at the proper place therealong. Subsequently the finger support 18 is adjustably positioned on the clamp so that the forward face 41 thereof will be opposite or laterally adjacent the forward face of the trigger 14 when the latter is in cocked position. Depending upon the individuals preference the face 41 may be positioned slightly ahead or slightly back or exactly opposite the trigger. Also the finger support 18 may be inclined at whatever angle is desired.

In shooting the firearm, the trigger finger, designated 45 and shown in broken lines in FIG. 4, is received through the trigger guard so that the inside of the end portion of the finger rests against and is steadied by the forward face 41 of the attachment. With the finger so supported, it is then an easy matter to activate the trigger mechanism of the gun by pulling straight back on the trigger thereby firing the gun without in any way deflecting it from alignment with the target.

Although I have illustrated and described a preferred form of my invention, I contemplate that various changes and modifications can be made therein-without departing from the invention, the scope of which is indicated by the following claims.

I claim:

1. A finger rest attachment for a firearm having a trigger and a trigger guard, comprising a clamp formed of a pair of complementary members having relatively deep, facing, trigger guard-receiving channels adapted to engage opposite sides of the trigger guard and a pair of laterally spaced screws extending through one member and threaded into the other member connecting said members and adapted to securely clamp the same to the trigger guard, a finger support member characterized by a slotted lower portion positioned at the outer side of said other of the complementary clamp members and an upper portion having a forward face adapted to be positioned laterally opposite the trigger to receive and support the inner side of the end portion of a trigger finger extending through the trigger guard, said lower portion and said upper portion being disposed to form an angle of somewhat more than 90 comprising a substantially reverse L-shaped member, and a screw extending through the slotted lower portion of said finger support member and threadedly mounted in the adjacent clamp member in a plane between said first-mentioned screws, said finger support member being adjustable pivotally about said 15 7 References Cited in the file of this patent UNITED STATES PATENTS Tower July 12, 1887 Wilson Dec. 8, 1936 Finnegan Dec. 23, 1958
