Abstract
A glass pattern breaking apparatus having a press roll which is rollably movable across a prescored glass bracket supported upon an aligned template for breaking out the prescored pattern. The press roll is provided with an elongated rigid core shaft covered by a pliable resilient body, and its ends are journalled in freely vertically movable slide mechanisms so that its weight may freely bear against the glass bracket. The core shaft may be hollow so that it can be filled with water or granular material whereby its weight can be changed to break out patterns from glass brackets of different thicknesses.
Claims8
In a glass pattern breaking apparatus of the type having a press roll rollably movable across a prescored pattern glass bracket supported on an aligned template for breaking out the prescored pattern, the improvement comprising
- a. a press roll including:
- 1. an elongated rigid core shaft, and
- 2. a resilient pliable body covering said core shaft, and
- b. means for floating said press roll in a plane substantially perpendicular to said template so that its weight freely bears against the glass bracket supported on said template to cleanly break out the prescored pattern.
