4 Claims.
This invention relates to sights for firearms and more especially to a sight for automatic pistols.
An object of the invention is a firearm rear sight which is easily and quickly adjustable both for windage and for elevation.
According to the invention, the rear sight is mounted on the firearm both for swinging movement longitudinally of the firearm and for bodily movement transverse thereof. The sight is locked in any desired position of adjustment by two spring-pressed plungers and the pressure applied to the plungers is regulated by adjustment of a single screw. To efiect adjustment of the sight, it is necessary merely to rotate the screw to reduce the pressure applied to the plungers, move the sight into its desired position of adjustment and then adjust the screw to restore the required holding pressure on the plungers.
Other objects, novel features and advantages of this invention will become apparent from the following specification and accompanying dra ing, wherein:
Fig. 1 is a side elevation of a pistol equipped with a sight embodying the invention;
Fig. 2 is a plan View thereof;
Fig. 3 is an enlarged section on the line 3--3 of Fig. 2, and
Fig. 4 is an enlarged section on the line 4-4 of Fig. 1.
The sight is herein disclosed as applied to an automatic pistol It having a sliding breech bolt ll. Near the rear end of the breech bolt is provided a transverse groove l2 which is somewhat more than semi-circular in cross-section. In this groove is arranged a cylindrical head l3 from which extends radially a plate l4 having a slot I5, the head and plate together constituting the sight. The sight is thus mounted on the breech bolt for swinging movement longitudinally of the breech bolt and for bodily movement transversely of the breech bolt. A bore It extends longitudinally of the breech bolt and traverses the groove l2. In the front end of the bore I6 is arranged a plunger l1 having a pointed end engageable with the head l3. A spring l8 urges the plunger ll toward the head l3 which is provided with a plurality of grooves or serrations IQ for receiving the edge of the plunger H. In the rear end of the bore 16 is provided a second plunger IS with a pointed end engageable with the head l3. A spring 2| interposed between the plunger 20 and a screw 22 threaded into the rear end of the bore I 6 urges the plunger l9 toward the head l3 which is provided with transverse grooves or serrations 23 New Haven, Conn.
1936, Serial No. 68,438 (Cl. 33-56) into which the pointed edge of the plunger 20 is receivable.
The engagement of the edge of the plunger [1 with the serrations I 9 holds the sight in any lateral position of adjustment while the engagement of the pointed edge of the plunger 20 in the serrations 23 holds the sight in any position of elevation adjustment. The pressure exerted by the springs 18 and 2| is regulated by the screw 22 which can be screwed into the bore sufliciently that the applied pressure holds the sight firmly in any position of adjustment. In order to change the adjustment of the sight the screw 22 is screwed outwardly of the bore l6 until the pressure applied to the sight by the springs l8 and 2| is suificiently reduced to permit easy swinging and/or lateral movement thereof. The sight is then moved to the desired position of adjustment and the screw 22 again screwed in to increase the pressure applied to the head I 3 until the sight is again locked in position.
Adjustment of the sight can easily and quickly be effected. Adjustment for windage is made by transverse movement of the sight while adjustment for elevation is made by swinging movement of the sight, as such swinging movement changes the vertical position of the bottom of the slot I5. The usual front side 24 is provided at the front end of the barrel for cooperation with the rear sight in the usual manner.
While the invention has been disclosed as applied to an automatic pistol, it is to be understood that the sight herein described may be used on other types of firearms as desired. Furthermore, it is to be understood that various modifications may be made in the structure herein described without in any way departing from the spirit of the invention as defined in the appended claims.
I claim:
1. In a firearm, a sight having a cylindrical head slidably and rotatably mounted in a groove in the firearm, a pair of plungers in a bore traversing said groove, said plungers being on opposite sides of said head, a spring pressing each plunger into engagement with said head, means on said head whereby said plunger may look the same in adjusted positions, and a screw threaded into said bore for adjusting the pressure applied by said springs to said plungers.
2. In a firearm, a sight having a cylindrical head slidably and rotatably mounted in a groove in the firearm, a pair of plungers in a bore traversing said groove and said plungers being on opposite sides of said head, means on said head whereby said plungers may lock the same in adilttili Film-m1 justed positions, a spring seated in said bore and pressing one plunger into engagement with said head, a second spring in said bore for pressing the second plunger into engagement; with said head and a screw threaded into said bore for engagement with said second spring to vary the pressure applied thereby.
3. In a firearm, a sight having a cylindrical head received in a groove in the firearm, a pair of plungers in a bore traversing said groove, said plungers being on opposite sides of said head, a spring pressing each plunger into engagement with said head, a screw threaded into said bore for adjusting the pressure applied by said springs to said plungers, said plungers having knife edge ends and said head having a series of horizontal serrations engageable by one plunger and a series of vertical serrations engageable by the other plunger.
4. In a firearm, a sight having a cylindrical head received in a groove in the firearm, a pair of plungers in a bore traversing said groove and said plungers being on opposite sides of said head, a spring seated in said bore and pressing one plunger into engagement with said head, a second spring in said bore for pressing the second plunger into engagement with said head, a screw threaded into said bore for engagement with said second spring to vary the pressure applied thereto, said plungers having knife edge ends and said head having a series of horizontal serrations engageable by one plunger and a series of vertical serrations engageable by the other plunger.
