Abstract
Abstract A gunsight mount for mounting a scope-type sight to an automatic handgun, such as a .45 automatic, has a housing including a channel for receiving the barrel and slide of the gun. The housing has an opening at the bottom, at the end most adjacent to the handle of the gun, for providing a clearance for the trigger guard. A protuberance is disposed at the bottom adjacent the slot and includes an adjustable stop member. The housing is supported on a mounting pin passing through the sides of the housing and through the slide stop pin bore of the gun. An elevational adjustment screw extends into the channel from the bottom of the housing for rigidly securing the mount to the gun while providing elevational adjustability. The scope-type sight may be fastened to the top of the housing.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
262 words
A mounting bracket for mounting a scope-type sight on a handgun, said handgun having a frame, a barrel supported on the frame, a handle disposed angularly relative to the barrel remote from the discharge end of the barrel, said frame including a trigger guard disposed about a trigger spaced below the barrel adjacent the handle, said bracket comprising a substantially rectangular housing having a channel extending longitudinally therethrough from a first end to a second end to define a spaced pair of side walls, a top wall and a bottom wall, said channel being of a size for receiving at least the barrel and a portion of the frame, said top wall including a planar exterior surface for supporting said sight, said bottom wall extending from the first end of the housing and having a terminus spaced from the second end, said bottom wall including an interior surface having a shape conforming substantially to that of said frame adjacent the trigger guard, each side wall having a bore intermediate said terminus and said second end, the bore in one side wall being aligned with the bore in the other side wall for receiving a pin extending from one bore to the other, a protuberance disposed on the exterior surface of said bottom wall and having a terminal surface substantially at said terminus, and adjustable stop means carried by said protuberance for extension from said terminal surface, whereby said mounting bracket may be supported on the frame by positioning said pin through said frame and securing said stop means against said trigger guard.
Claim 2
Dependent Claim
262 words
A mounting bracket for mounting a scope-type sight on a handgun, said handgun having a frame, a barrel supported on the frame, a handle disposed angularly relative to the barrel remote from the discharge end of the barrel, said frame including a trigger guard disposed about a trigger spaced below the barrel adjacent the handle, said bracket comprising a substantially rectangular housing having a channel extending longitudinally therethrough from a first end to a second end to define a spaced pair of side walls, a top wall and a bottom wall, said channel being of a size for receiving at least the barrel and a portion of the frame, said top wall including a planar exterior surface for supporting said sight, said bottom wall extending from the first end of the housing and having a terminus spaced from the second end, said bottom wall including an interior surface having a shape conforming substantially to that of said frame adjacent the trigger guard, each side wall having a bore intermediate said terminus and said second end, the bore in one side wall being aligned with the bore in the other side wall for receiving a pin extending from one bore to the other, a protuberance disposed on the exterior surface of said bottom wall and having a terminal surface substantially at said terminus, and adjustable stop means carried by said protuberance for extension from said terminal surface, whereby said mounting bracket may be supported on the frame by positioning said pin through said frame and securing said stop means against said trigger guard.
Claim 3
Dependent Claim
59 words
A mounting bracket as recited in claim 1, wherein said adjustable stop means comprises a threaded bore extending longitudinally therethrough, an abuttment member disposed in said threaded bore and adapted to extend from said terminal surface, and screw means threaded into said bore from the end opposite said terminal surface for moving said abuttment member beyond said terminal surface.
Claim 4
Dependent Claim
37 words
A mounting bracket as recited in claim 1, including second adjustable stop means in said bottom wall for extending from said interior surface into the channel for providing elevational adjustment of said bracket relatively to said barrel.
