Abstract
Abstract A bullet mold for molding bullets of the wad cutter type which are generally cylindrical and having flat nose portions and base portions; comprising three plates, one of which has a cylindrical cavity therein, another of which has a sprue opening and cutter, and the other of which forms a backup plate for the opposite end of the cylindrical cavity from the sprue cutter, and means for pivotally shifting the sprue cutter and the backup plate out of alignment with the cavity in order to eject a cylindrical bullet therefrom.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
97 words
A bullet mold comprising: a cavity member having spaced opposite sides; a generally cylindrical cavity extending through said cavity member; a sprue cutter plate on one side of said cavity member and partially enclosing one end of said cavity, and a backup plate disposed at the opposite side of said cavity member and enclosing the opposite end of said cavity in sealing relationship therewith; means for supporting said plates in movable relation to said cavity member to cause movement of said plates relative to said cavity member in a direction laterally of the axis of said cavity.
Claim 2
Dependent Claim
97 words
A bullet mold comprising: a cavity member having spaced opposite sides; a generally cylindrical cavity extending through said cavity member; a sprue cutter plate on one side of said cavity member and partially enclosing one end of said cavity, and a backup plate disposed at the opposite side of said cavity member and enclosing the opposite end of said cavity in sealing relationship therewith; means for supporting said plates in movable relation to said cavity member to cause movement of said plates relative to said cavity member in a direction laterally of the axis of said cavity.
Claim 3
Dependent Claim
42 words
The invention, as defined in claim 1, wherein: said plates are substantially flat at opposite ends of said cavity and opposite sides of said cavity member to produce a wad-cutter-type bullet having a substantially flat base and a substantially flat nose portion.
Claim 4
Dependent Claim
50 words
The invention, as defined in claim 1, wherein: said cavity member is provided with a handle portion extending away from said cavity; a handle member mounted on one of said plates and adapted to move them relative to said cavity member for moving said sprue cutter relative to said cavity.
Claim 5
Dependent Claim
110 words
The invention, as defined in claim 1, wherein: said sprue cutter plate and said backup plate are pivotally mounted on said mold member; an operating handle pivotally mounted on said sprue cutter plate; said operating handle having a punch projection pivotally movable into alignment with said cavity and pivotally movable to eject a bullet from said cavity, when said plates are pivoted out of alignment therewith; and means adapted to spread said plates apart at an opposite side of said pivotal mounting bolt from said cavity in order to maintain said plates in close fitted proximity with opposite sides of said cavity member and at opposite ends of said cavity.
Claim 6
Dependent Claim
105 words
The invention, as defined in claim 1, wherein: said cavity is provided with a slightly enlarged diameter portion adapted to form an external ridge on a bullet cast therein, said enlarged portion being adjacent one end of said cavity and adjacent one of said plates; the central axis of said cavity being substantially at right angles to opposite sides of said cavity member; said plates being substantially flat adjacent said ends of said cavity and opposite sides of said cavity member in order to produce a bullet of generally wad cutter shape and of configuration having a flat nose and a substantially flat base portion.
