Abstract:
A glass tapping tool for tapping glass along a score-line that has been previously cut into the glass comprising:a hollow tube with a first end and a second end; a stationary striking member attached to the first end of the tube for striking a piece of glass which has been previously cut along a score-line; a cap with a mount for holding a glass cutting head, the mount having a bore therethrough; a slidable hammer with a first end and a second end, slidably mounted inside the tube so that the second end of the slidable hammer protrudes outside the second end of the hollow tube, the second end of the slidable hammer having an axial bore for receiving the cap so as to create an enclosed internal cavity which is in communication through the bore with the glass cutting head; and an elastic member means for elastically coupling the stationary striking member with the slidable hammer so when a user pulls the part of the slidable hammer protruding from the hollow tube in an axial direction away from the hollow tube, the elastic member means produces a force in opposite direction which causes the slidable hammer through the elastic member means to strike the stationary striking member, when the user releases the slidable hammer, so as to tap the glass along a score line and causing the glass to break along the score line.
