Abstract
The invention relates to a device for cutting material such as metal rod. The device comprises a diaphragm type air brake chamber having a wedge mounted to an output shaft of the chamber, a cutting assembly mounted to the air brake chamber, the assembly comprising two pivotally mounted cutting members with opposed blades with the members biased to maintain an opening between the blades, and a handle for gripping the device rearwardly of the cutting assembly. The device is configured so that on actuation of the air brake chamber, the wedge is driven between ends of the cutting members distal the blades to cause the blades to pivot towards each other.
Claims14
A cutting device comprising:
- a diaphragm type air brake chamber having a wedge mounted to an output shaft of said chamber;
- a cutting assembly mounted to said air brake chamber, said assembly comprising two pivotally mounted cutting members with opposed blades, wherein said members are biased to maintain an opening between said blades;
- and
- a handle for gripping said device rearwardly of said cutting assembly;
- wherein said device is configured so that on actuation of said air brake chamber, said wedge is driven between ends of said cutting members distal said blades to cause said member blades to pivot towards each other.
The device according to claim I comprising first and second handles.
A cutting device comprising:
- a diaphragm type air brake chamber having a wedge mounted to an output shaft of said chamber;
- a cutting assembly mounted to said air brake chamber via a frame, said assembly comprising two pivotally mounted cutting members with opposed blades, wherein said members are biased to maintain an opening between said blades with said biasing by way of coil springs extending in opposite directions from distal ends of said cutting members to said frame;
- and
- a handle for gripping said device rearwardly of said cutting assembly, said handle having adjacent thereto a valve for controlling flow of air to said chamber;
- wherein said device is configured so that on actuation of said air brake chamber, said wedge is driven between roller bearings mounted at said distal ends of said cutting members to cause said blades to pivot towards each other.
