Abstract
A pair of hair cutting or pet scissors that have two blades operationally connected by a dual taper, dual threaded bolt and a nut for adjustment and a nut for assembly. The assembly allows for the scissor blades to be brought into tighter or looser frictional contact with each other without being disassembled. There is a tool that engages the bolt to rotate either of the nuts separately for adjusting the feel of the blades or for disassembly and repair or sharpening.
Claims7
A pair of scissors, capable of separate blade tensioning and blade disassembly, comprising:
- a first scissors blade having an first inner face and a first outer face with a concave first recess formed thereon, said first recess having a first orifice formed therethrough;
- a second scissors blade having an second inner face and a second outer face with a concave second recess formed thereon, said second recess having a second orifice formed therethrough;
- a locking nut having an internally threaded post extending therefrom;
- an internally threaded tension nut;
- a disassembly bolt having a shaft with an exterior upper thread and an exterior lower thread formed thereon, wherein one of said upper thread and said lower thread is a left hand thread and one is of a right hand thread;
- and
- wherein said first inner face and said second inner face are in contact and said first orifice and said second orifice in alignment, and said locking nut resides in said first recess with said threaded post extending through said first orifice;
- and
- wherein said tension nut is threadingly engaged on said upper exterior thread, and said disassembly bolt resides in said second recess with said shaft passing through said second orifice, and said lower exterior thread threadingly engaged with said post of said locking nut.
