GLASS-CUTTING Boeien.y f

Application led November 14, 1921. Serial No. 515,111.

To all whom it may concern:

Be it known that we, FRANK BUKACHEK and OsoAR A. GARBUsH, citizens of the United States, residing at Pine City, in the county of Pine and State of Minnesota, have invented a new and useful Glass-Cutting Board, of which the following is a specification.

Our invention relates to glass cutting boards, and the object is to provide a convenient, vefficient and otherwise improved board upon which to readily measure, cut and separate the cut parts of glass of any thickness used for window lights, picture frames, etc. i s

In the accompanying drawing:

Fig. 1 is a top or plan view of our improved glass board with a piece of glass placed upon it in position to be cut.

Fig. 2 is aright hand edge view of Fig. 1.

Fig. 3 is a lower edge view` of Fig. 1.

Referring to the drawing by reference numerals, 1 designates the board proper. It

is reinforced and stiffened by cleats 2 secured to its under side, and in the upper side it is provided with a groove 3 serving as a clearance for the fingers of the operator when he desires to pick upthe glass from the board.

Parallel to said groove is secured upon one edge of the board a glass measuring and guiding scale bar 4, and at right angle to said bar and about half an inch from it is a heavier bar 5, which has its outeredge 6 spaced about one eighth of an inch inward from the edge 7 of the board, andits inner edge beveled at 8 and providedwith a scale of inches and yfractions of inches startingV at the point 9 and extending with increased numbers to any desired length according to the size of the board. This scale bar 5 vis slidable up and down on studs 10 fixed in the board. The space 11 betweenk the two scale bars is a clearance for the glass cutter to pass through in cutting the glass. The scale of inches and fractions of inches on the bar 4 does not start at the point 12 but at a point 13, that is, at the crease kwhich an ordinary glass cutter drawn along the inner edge of bar 5 cuts about one-sixteenth of an 50 inch from said edge ofthe bar. In the Voperatitui or use of the board, the

glass is placed as 15 upon` vthe board and guided by the scalebar 4; is pushed outwardr underneath the bar5, the latter being at the time suiiiciently raised for the purpose. When the previously squared corner 16 of the glass reaches the desired number or mark on bar 1, the operator presses downward on the bar 5 while .drawing the cutter along the edge 5aL of the bar and after the score 14 is thus produced in the glass the latter is pushed outward until the score appears close outside the edge 6 ofthe bar, the portion 15*v of theglass is then forced downward by one hand and broken at the score while the other hand is resting on the bar 5 4 i i to prevent tipping of the main body of the. glass.` If the glass is further to becut, say at the'line 17 it is turned and pushed with said line to the position of the' score le'andl is there cut in the manner already described.l whereupon the ready cut piece 15 is picked y up and removed. Such picking up, 4turning and removing ofthe glass is greatlyv facili-4 tatedk by the groove 3 which admits the opp erators Afingers to get under the glass to pick it up quickly and also to put it down without dropping it. l 1

It will be understood that we consider the slight projecting 18 of the board beyond the edge 6 of the bar 5-as avaluable feature since yexperimenting has demonstrated thatl V said feature causes the glass to break with much more square and smooth ledges than when the portion 15X. is all unsupported beypndthe face 6 of the bar 5 holding the g ass. 1

What we claim is:

1v. A glass cutting board having one edge near which to break the glass'after it has been scored by the cutting tool, vertical posts fixed 'in thexboard near said edge, and a main scale bar having apertures making itv4 slidable up and down on the posts, said edge of the board projecting a short 'distanceoutward beyond said scale bar. l

2. The structure; speciliedin claim 1, and

a second soaie oar .fixed upon the board at 3. The Structure specified in ela-im 2, Said right angles to the main scale bai, said seoboard having in its top a groove formed in lo ond bai' having its scale increased fiom the parallel rela-tion to the fixed side bai'.
