Original application .l'niy 5, 1960, Ser. No. 40,582, now Patent No. 3,088,378, dated May 7, 1963. Divided and this application Sept. 5, 1962, Ser. No. 221,579
3 Claims. (Cl. 42-1) The present invention relates to an improved pistol design and more specifically to a construction and arrangement which facilitates the shooting and aiming of a pistol, particularly where large caliber cartridges are used and where a plurality of shots are to be fired in succession.
The present invention is a division of my copending application Serial No. 40,582, filed July 5, 1960, now Patent No. 3,088,378.
An object of the invention is to provide a novel sight structure for the pistol which can be easily and quickly installed in the top of the pistol frame and can be readily adjusted to correct for windage and elevation.
Other features and advantages of the invention will be apparent from the specification and claims when considered in connection with the accompanying drawings in which:
FIGURE 1 is a side elevational view of the pistol in assembled relation.
FIG. 2 is a top view of FIG. 1.
FIG. 3 is a sectional view taken along line 3-3 of FIG. 1 showing the sight in position in the frame.
As shown in the drawings, the pistol comprises a frame consisting of a grip portion 11 having a trigger guard 12 integral therewith and a barrel-receiving portion 13 adapted to be secured to the grip portion and a magazinereceiving portion or member 14, as shown in FIG. 1, for receiving the magazine 48 provided with a cylindrical casing 54 disposed between the portion 14 and a closure 59. The rear end of the magazine is provided with a T-shaped rib 73 integral with the end thereof which is adapted to be inserted into a T-shaped slot 74 in the magazine-receiving portion 14 to securely anchor the magazine and locate the magazine on the frame. The magazine is locked in position by a notch '75 in the rib 73.
The rear sight of the present invention is carried by the pistol frame to the rear of the member 14 and is disposed in the frame above the breechblock 18 which is fixed in position by the pin 21. The breechblock is provided with grooves to receive side rails 41 of the sliding barrel (not shown) curled in the barrel-receiving portion 13.
Mounted in the breechblock is a slidable housing 33 adapted to carry a striking member (not shown) and having depending flanges 33b for carrying the sear link 37.
As shown in the drawings, the sight is mounted in the top of the grip portion of the frame and comprises a split cylindrical sleeve 86 having a radial flange 87 projecting therefrom and provided with a sighting notch 88. The sleeve is adapted to be inserted into a transverse cylindrical recess 88a opening in the top of the frame, as shown in FIGS. 1 and 2, with the radial flange projecting above the top of the frame. Means for locking the sleeve in adjusted position may take many forms. In the illustrated form of the invention it comprises a pair of opposed conical elements 89, 90 mounted within the sleeve, as shown in FIG. 3, and connected by a threaded member 91 to draw them together and expand the split sleeve into clamping relation with the walls ice of the recess. The split cone 90, as shown in FIG. 3, will at the same time be forced into gripping relation with the threaded member 91 to prevent inadvertent release of the clamping relation which would permit movement of the sleeve in the frame and destroy its adjustment. With this construction the sight can readily be adjusted for windage by sliding the sight laterally in the recess and for elevation by rotating the sight in the recess.
As noted in FIGS. 1 and 2, the frame can be provided with indicia 92 for aiding in windage adjustment and with indicia 93 for the adjustment for proper elevation. The magazine at the forward end has a front sight 94 thereon to cooperate with sighting notch 88 in aiming the pistol.
Variations and modifications may be made within the scope of the claims and portions of the improvements may be used without others.
I claim:
1. A sight for use in a firearm having a frame on the top thereof provided with a substantially cylindrical transverse recess opening in the top surface of said frame, comprising a longitudinally split cylindrical sleeve disposed in said recess and having a radial flange projecting through said opening in the top surface and provided with a sight opening, said sleeve being longitudinally slidable and rotatable for adjustment in said recess, and means for expanding the split sleeve into gripping relation with the walls of the recess to hold said sleeve and sight opening in adjusted position.
2. A sight for use in a firearm having a frame on the top thereof provided with a cylindrical transverse recess opening in the top surface of said frame, comprising a longitudinally split cylindrical sleeve disposed in said recess and having a radial flange projecting through said opening in said top surface and provided with a sight opening, said sleeve being longitudinally slidable in said recess for moving said flange and sight to correct for windage and rotatable about the longitudinal axis thereof for moving said flange and sight opening to correct for elevation, and means including opposed cones for expanding the split sleeve into gripping relation with the walls of the recess to hold said sleeve and sight opening in adjusted position.
3. A sight for use in a firearm having a frame on the top thereof provided with a cylindrical transverse recess opening in the top surface of said frame, comprising a longitudinally split cylindrical sleeve disposed in said recess and having a radial flange projecting through said opening in the top surface and provided with a sight opening, said sleeve being longitudinally slidable and rotatable for adjustment in said recess, and means comprising opposed conical expander elements disposed within the sleeve and threaded means for moving said elements and expanding the split sleeve into gripping relation with the walls of the recess to hold said sleeve and sight opening in adjusted position.
