UNITED STATES PATENT OFFIoE.
FRANCIS VOERNER AND SAMUEL E. NIES, OF READING, PENNSYLVANIA.
GLASS-CUTTING FRAME.
SPECIFICATION forming part of Letters Patent No. 342,159, dated May 18, 1886.
Application filed February .23, 1836. Serial No. 192,909. (No model.)
To all whom it may concern:
Be it known that we, FRANCIS \VOERNER and SAMUEL E. NIEs, both citizens of the United States, residing in Reading, Berks county, Pennsylvania, have invented certain Improvements in Glass Cutting Frames, of which the following is a specification.
The object of this invention is to construct a glass-cutting frame or table having a sliding guided straight-edge capable of being locked in different positions, thus insuring the accurate cutting of the glass, as fully described hereinafter.
In the accompanying drawings, Figure 1 is perspective View of this improved frame or table. Fig. 2 isasectional view on the line 1 2, Fig. 1, drawn to an enlarged scale. Fig. 3 is a sectional view on the line 1 2, Fig. 2, drawn to a still larger scale; and Fig. aisaplan view of apart ofoneofthe guide-pieces of the frame.
A represents a straight-edge having crosspieces a a at each end provided with ribs (0, which slide in longitudinal ways I) b on each side of the frame or cutting-table B, said crosspieces having each a wide bearing-surface on the frame tending to keep the straight-edge at right angles at all times with the length of the frame. A rod, D, having its bearings in the straightedge A, has at each end projections or pawls (Z d, which pass downward through slots in the straight-edge and are adapted to engage with ratchet-racks E E, (see Fig. 3,) secured to the frame B. These pawls tend to hold the straight-edge firm and prevent it from slipping when cutting the glass. The racks E E are fixed in guide-pieces F F, which are secured to or form part of the frame B on each side.
The rod D hasathumb-lever, f, fixedthereto, and under thislever is a spring, 9, tending to keep the pawls d d in gear with the racks E E.
When it is desired to adjust the straightedge, if the adjustment be in the direction of the arrow, Fig. 3, the pawls will slip over the teeth in the racks E E; but if it be desired to adjust the straight-edge in the opposite direction the lever f is depressed to free the pawls from the racks E E. A projection, 71, at one end of the bed of the frame B has a straight inner edge, against which and along the inner edges of the guide-pieces F F the glass is placed to be cut, asindicated by dotted lines in Fig. 1.
Graduation-marks c e are formed in each of the guidepieces F F, and the teeth of the racks E E are so cut as to correspond with these graduations, in order that the straightedge A may be adjusted by the operator to any desired measurement, and be held firm by these racks while the glass is cut.
\Vc claim as onr invention- 1. The combination of a glass-cutting frame or table having guideways on opposite sides with a straight-edge having erosspieces at each end adapted to traverse on said ways, substantially as set forth.
2. The combination of a glass-cutting frame or table with a straight-edge, A, and toothed retaining-racks E E, and pawls, substantially as set forth.
3. The combination of aglass-cutting frame or table with a straight-edge, A, graduated side pieces, F F, racks E E, and pawls, as and for the purposes substantially as set forth.
4. The combination of a glass-cutting frame or table with a straight-edge, A, rod D, carrying pawls, and a lever, f, a spring, 9, and racks E E, substantially as and for the purposes specified.
In testimony whereof we have signed our names to this specification in the presence of two subscribing witnesses.
FRANCIS \VOERNER. SAMUEL E. NIES.

CHARLES F. HELLER, WM. A. H. SCHMEHL.
