TRIGGER PULL FOR SMALL ARMS Filed Feb 1, 1945 /0 AMMm/m r Patented July 22, 1947 UNlTED srares rarest (Granted under the act of March 3, 1883, as amended April 30, 1928; 370 0. G. 757) Claims.
The invention described herein may be manufactured and used by or for the Government for governmental purposes without the payment to me of any royalty thereon.
This invention relates to trigger pull arrangements for small arms such as rifles, pistols, revolvers, shotguns and the like, and more particularly, to arrangements for securing a creepless trigger pull effect, similar to the efiect obtained in breaking a brittle rod.
A main object of this invention, therefore, is to provide a method and means for obtaining a creepless trigger pull for small arms.
A further object of this invention is to provide a method and means for obtaining a creepless trigger pull for small arms by utilizing a magnetic field to produce the quick breakaway efiect.
Further objects of this invention will appear from the following description and claims, and from the accompanying drawings, wherein:
Figure 1 is an elevational view with parts broken away of a portion of a rifle mechanism employing a trigger pull arrangement in accordance with this invention.
Figure 2 is a partial view similar to Figure 1 but showing a modification of the trigger pull arrangement adapted to provide slack in the trigger.
Figure 3 is a detail view partly in cross-section of a modified permanent magnet structure for a trigger pull arrangement according to this invention.
Figure 4 is an enlarged cross-sectional view taken on line 44 of Figure 2.
Figure 5 is a detail view partly in cross-section of a further modification of the invention.
It is very desirable in small arms such as rifles, pistols, revolvers, shotguns, and the like, to provide a trigger pull arrangement, where at the moment of trigger release, the force opposing the pull on the trigger is very rapidly reduced so as to result in a sharp clean breakaway of the trigger mechanism from its retaining structure. The desired effect is analogous to the result which would be obtained if the trigger was held back by a thin brittle rod such as a glass rod and the trigger pull resulted in the gradual building up of stress in the rod (considered to be acting as a beam) and the sudden rupture thereof, yielding complete release of the trigger. Such a trigger action would be considered substantially creepless and would be highly effective.
Since a glass rod construction is obviously impractical in a rifle or other firearm, it is proposed by this invention to obtain the same, or a closely similar, efiect by distorting the magnetic field surrounding a permanent magnet. Referring to the drawings, Fig. 1 discloses one arrangement where this method of trigger control is shown as applied to a bolt action rifle. In the other drawings, similar reference numerals. refer to parts identified by reference numerals in Fig. 1.
In Fig. 1, the bolt of the rifle is designated by reference numeral I. Bolt I is provided with a cocking lug 2 which is normally engaged, in cocking position by one arm 3 of a sear lever A, pivotally supported in the cavity provided therefor in the rifle. Another arm 5 of scar lever l is engaged by a trip lug 6 formed on the trigger body 1. Upward movement of arm 5 is cushioned by a coiled pressure spring 3 connected between the upper surface of arm 5 and an adjacent stationary wall of the cavity. Spring 8 biases sear lever 4 to a cocking position. Upward movement of lug 6 forces arm 3 out of obstructing position with respect to lug 2 and releases bolt l to fire the weapon.
Trigger body 1 is provided with a forwardly projecting paramagnetic arm 9 which extends in normal close proximity to a permanent magnet l9 and is biased to this position by a pressure spring H retained in an adjustable cu member l2, threadedly engaged with an external wall of the trigger housing. Permanent magnet H) preferably having a magnetomotive force in excess of that of ordinary permanent magnets is appropriately secured to a stationary support member l3 of non-magnetic material such as wood. Trigger body 1 is made of magnetic material such as soft steel.
When the trigger is pulled, arm 8 is moved away from magnet Hi, and at a critical position where the air gap between arm 9 and magnet l0 reaches a value where the magnetic force on arm 9 cannot balance the pulling force on the trigger, the initial magnetic field is weakened and the magnetic flux pattern around permanent magnet Iii shifts to a new form. The sudden shift of the magnetic flux pattern leaves the pulling force on trigger l unopposed and provides the desired sudden breakaway release of the trigger,
The amount of pulling force required to produce the desired quick release may b regulated by adjusting cup member I2 to provide the optimum initial pressure of spring on arm 9.
In the embodiment of Fig, 2 means is provided for introducing a certain amount of slack in the trigger action before the sharp breakaway release effect is obtained. In this embodiment the trigger body, designated as I? is pivotally mounted on a pin I8 coaxially with a sear actuating lever I9. Sear actuating lever I9 is provided with a trip lug 20 adapted to urge arm of scar lever 4 upwardly to release bolt I when lever I9 is rotated in a clock-wise direction. Sear actuating lever I9 is further provided with paramagnetic arm 2! provided at its end with an integral open sleeve portion 22 having a lower flange 23. Trigger body I! is provided with an arm 24 positioned within said open sleeve portion 22 and connected to lower flange 23 by a compression spring 25 so that the pull on the trigger is cushioned by spring 25 until said spring goes substantially solid, whereupon said pull is transmitted to arm 2!. Arm 2| is normally positioned by adjustable cup member l2 and spring I I so that it is closely adjacent to permanent magnet l9. As arm 2| is moved downwardly by the trigger pull, the sharp release action is obtained as described in connection with the embodiment of Fig. 1.
Fig. 3 discloses a modification of the permanent magnet employed in the trigger release arrangement according to this invention, said magnet comprising a horseshoe magnet having arms 26, 21 connected-by magnetic yoke, the ends of the arms being of opposite polarity so that a very high flux density is normally obtained through the trigger arm element 29 positioned adjacent their end faces. By this arrangement, the breakaway effect produced by the rapid decay of the initial magnetic field is considerably enhanced. This structure may be employed with either the embodiment of Fig. 1 or the embodiment of Fig. 2. The horseshoe magnet is secured by appropriate fastening means to an appropriate nonmagnetic member 28 forming part of the wall structure of the trigger cavity.
Although, as disclosed in the foregoing embodiments the permanent magnet is stationary, the magnet may be instead mounted on the movable trigger arm element and may cooperate with a suitable stationary element of magnetic material to produce the desired quick release action. As shown in Fig. 5, the forwardly projecting trigger arm 32, preferably of non-magnetic material, has a permanent magnet 3! affixed to its upper surface. The stationary element 30 is formed of iron or soft steel and is secured by appropriate fastening means to the member 28 forming part of the wall structure of the trigger cavity. It will be understood that the modifications of Figs. 1 through 4 may be appropriately modified by placing the magnet on the movable trigger arm and providing a cooperating stationary magnetic element.
While certain specific embodiments of trigger pull arrangements for small arms have been disclosed in the foregoing description, it will be understood that various modifications within the spirit of the invention will occur to those skilled in the art. Therefore, it is intended that no limitations be placed on the invention other than as defined by the scope of the appended Claims.
