Abstract

A device for holding and cutting a thin plate of sheet material such as glass or plastic into a plurality of smaller rectangular plates with a hand-manipulated tool. A rigid base is formed with a recess which forms a depressed platform for receiving and firmly holding a plate therein. A pair of spaced posts are mounted on the base and are located at opposite sides from each other. A template is removably mounted on the base by the posts which extend into a selected pair of a plurality of holes formed in the template. A plurality of spaced, linearly extending grooves are formed in the template for guiding a cutting tool in a straight line when cutting the plate which is mounted between the base and template. The template is rotated 90.degree. and repositioned on the base posts after the plate is cut in a first direction by the cutting tool which is moved along one or more of the template grooves, whereby the template grooves then form guides for cutting the plate in a transverse direction with respect to the previous plate cuts. Selection of the appropriate grooves determines the size of the smaller plate or plates cut from the main plate.

Dependent claims

A device for cutting a thin main plate of material into a plurality of smaller size, rectangular-shaped plates, said device including:

(a) base means for holding a main plate in a fixed position;
(b) a template removably mounted on the base means and adapted to overlie a main plate when held on the base means;
(c) a plurality of spaced, parallel, linear guide grooves formed in the template, said grooves being adapted to slidably receive the end of a cutting tool therein for cutting a main plate in a line along a selected guide groove;
and
(d) mounting means formed on the base means and template for mounting the template on the base means in a first cutting position in which the guide grooves extend in a first direction and in a second cutting position in which the guide grooves extend in a second direction transverse to said first direction, whereby a cutting tool when moved along certain selected guide grooves in the template first position and then moved along certain selected guide grooves in the template second position cuts a predetermined sized rectangular-shaped plate from the main plate.
