Claims
- 1. A shearing blade configuration for shearing machine jaws comprising: an upper shearing blade assembly including
- (a) a forward blade disposed in a first vertical plane;
- (b) at least one rearward blade having its cutting surface located contiguous with the cutting surface of the forward blade, and disposed in a second vertical plane parallel to the first plane, the blades positioned in laterally stepped relation;
- (c) the forward and rearward blades forming an obtuse angle therebetween; a lower shearing blade assembly including
- (d) a forward blade disposed in a third vertical plane, parallel to the first and second planes;
- (e) at least one rearward blade having its cutting surface located contiguous with the cutting surface of the lower forward blade, and disposed in a fourth vertical plane parallel to the first, second and third planes, the lower blades positioned in laterally stepped relation;
- (f) the lower forward and rearward blades forming an obtuse angle therebetween to ensure closure of the forward upper and lower blades before the rearward upper and lower blades;
- the forward blades and the rearward blades having corresponding lateral surfaces in contact with one another upon closure of the jaws for interlocking the jaws and preventing their lateral separation.
- 2. The configuration set forth in claim 1 wherein the upper blade assembly includes two rearward blades located in coplanar relation, their cutting surfaces being adjacent one another.
- 3. The configuration set forth in claim 1 wherein each of the upper and lower blade assemblies includes one rearward blade.
- 4. The configuration set forth in claim 1 wherein each of the upper and lower blade assemblies includes two rearward blades located in coplanar relation, their cutting surfaces being adjacent one another.
- 5. The configuration set forth in claim 1 together with means for selectively rotating the jaws 360.degree..
