GLAZIERS POINT.

SPECIFICATION forming part of Letters Patent No. 714,516, dated November 25, 1902. Application led February 3, 1902. Serial No. 92,311. (No model.)

To a/ZZ whom t may concern.-

Beit known that I, THERON N. PARKER, a citizen of the United States, and a resident of the city of New York, borough of Brooklyn, in the county of Kings and State of New York, have invented new and useful Improvements in Glaziers Points, of which the following is a full, clear, and exact description.

My invention relates toa fastening used by glaziers for securing window-panes in the sashes of windows.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure l is afront elevation showing certain details in section. Fig. 2 is a vertical section, somewhat enlarged, upon the line 2 2 of Fig. l. Fig. 3 is a horizontalsection, somewhat enlarged, upon the line 3 3 of Fig. l; and Fig. 4 is a perspective view of the device.

A sash or other frame l is provided with beads 2 3 for engaging the outer edges of the glass in the usual manner. The panes of glass are shown at il 5 and may be lapped, if desired, as shown at 6. The usual filling of putty is shown at 7 and may be omitted, if desired, as shown at 8. The fastenings are preferably of two sizes, as shown at 9 l0.

The details of the metallic fastening will now be described, reference being had toFig. 4. A triangular bit of sheet metal, such as zinc or iron, is bent into the shape shown, and thus presents angular corners a and c. The middle is bent into a V-shaped crease b, which extends from a point intermediate of the ends a and c to near the apex d of the angle opposite. The lines upon which the bit of metal are bent are shown at e, f, and g. It will be observed that the bending of the metal upon each of these lines forms an angle in cross-section as compared with the general plane of the bit of metal. It will be observed, too, that the three lines e, f, and g radiate from the apex d. The shape ofthis metallic fastening is such as to adapt it to a great variety of uses acceptable to the glazier. It is strong and reliable and possesses a certain amount of resilience, which is 0f great importance in securing glass in place. The fastenings can be placed around the overlapping edges of panes of glass, so that the'lap will hardly be noticed, and the joint thus formed is a perfect union and is practicallyair-tight. They can also be used as other glaziers points are now used.

By giving the fastenings the shape described a good driving-surface is formed for the'hammer and great rigidity is secured.

The device presents a broadv bearing for the hammer or the thumb, as the case may be, and distributes the strain more thoroughly than has been the case heretofore.

Having thus described my invention, I

claim as new and desire to secure by Letters Patent- As an article of manufacture, a glaziers point comprising a bit of sheet metal having a general triangular shape and bent along three straight lines diverging from the apex of one of its angles to as many points in the edge opposite said angle, saidbit of metal being so bent along said lines as to form two triangular planes in alinement with each other, and intersected by a central. crease having a V-shaped cross-section, the arrangement being such that said planes are free to fit closely against any fiat surface, while the end of said V- shaped crease affords a broad bearing, whereby said bit of metal may be driven.

In testimony whereof I have signed my name to this specilication in the presence of two subscribing witnesses.

THERON N. PARKER.
