Abstract
A nut cutting tool in which a cutting head includes a yoke for embracing a nut to be cut and for supporting a fixed blade as close as possible to the nut, the cutting head guidably supporting a moveable cutter in a cutting plane toward the fixed blade and nut by a thrust from a pressure exerting means at right angles to the cutting plane including a second guidable element in the form of a wedge block operatively associated with the pressure exerting means and having an inclined cam surface facing the non cutting end of the movable cutter for forcibly urging the latter toward the nut to be cut.
Claims7
A nut cutting tool comprising:
- (a) a cutting head;
- (b) a yoke mounted on said cutting head for embracing a nut to be cut;
- (c) a fixed cutting blade mounted on said yoke for engaging a nut to be cut;
- (d) a movable cutting knife;
- (e) a first named guideway formed on said cutting head for supporting and guiding said movable cutting knife along a cutting plane toward said fixed cutting blade and nut to be cut;
- (f) a tubular handle on one end of said cutting head opposite said yoke and having an axis extending at right angles to the cutting plane of the movable cutting knife;
- (g) pressure exerting means movable axially of and within said tubular handle;
- (h) a second named guideway formed in said tubular handle adjacent the non-cutting end of said cutting head and in communication with the first named guideway;
- and
- (i) a cam block arranged in said second named guideway for movement therein by said pressure exerting means, said cam block having a cam surface thereon disposed to face the after end of said movable cutting knife for wedgingly driving said movable cutting knife toward a nut to be cut in response to the operation of said pressure exerting means.

- (j) said yoke having a bight portion for supporting said fixed blade at the cutting plane and a pair of side arms removably mounted on said cutting head in a fixed disposition relative to the nut to be cut,
- (k) said cutting head having a pair of shouldered sides formed thereon to receive the free ends of said pair of side arms of said yoke, each of said shouldered sides of said cutting head having a plurality of apertures formed vertically thereon and spaced longitudinally thereof in parallelism with said cutting plane;
- and
- (l) pin means on each of said arms of said yoke adapted to fit into any pair of apertures in said shouldered sides of said cutting head on opposite sides of said cutting plane to support the fixed blade on the bight portion of said yoke as close as possible to the nut to be cut.
