BRAD FOR FASTENING WINDOW-GLASS.

Specification of Letters Patent.

Patented J nly 8, 1 913.

Application filed August 22, 1912. Serial No. 716,348.

To all whom/2'15 may concern:

Be it known that I, GOTTHELF M. NAU- MANN, a citizen of the United States, residing at Cleveland, in the county of Guy; hoga and State of Ohio, have invented certain new and useful Improvements in Brads for Fastening l/ViIlClOW-GrlilSS, of which the following is a specification.

My invention relates to a glaziers brad or point adapted to fasten glass in wooden sashes, the same being a new article of manufacture and ale.

In the accompanying drawings, Figure 1 is a perspective View of the brad or point alone. Fig. 2 is a direct perspective of a section of a window sash s and two glasses edge to edge and a brad overlapping both glasses. Fig. 3 is a perspective view of a small section of a hot-bed sash wherein the glasses overlap from above and tend to slide down unless specially fastened by the brad.

The brad, point or fastener a is constructed as shown from sheet metal. and preferably of brass so as to make it durable and avoid the tendency to rust which iron or steel are liable to. The said brad has a body 2, a V-shapcd driving point 3 at the middle of said body and right angled rearwardly bent wings or flanges t at its sides of the full width of the said body and of a depth relatively about as shown. The said point is of less width at its base than the body of the brad as between its sides and this leaves shoulders on the lower edge of the brad at each side oi. the base thereof which in any case is the driving limit of the brad, and the said shoulders are flush with the lower edges oi the flanges t. It follows when the brad is driven its full depth into the sash that the said shoulder 5 and the lower edges of the flanges will alike bear on the sash and serve as braces for sustaining the brad against the glass, especially when used as seen in Fig. 2. In Fig. 3 the glasses 6 overlap as usual in hot bed sashes and the brad is driven in laterally and one of the flanges or lips l engages the edge of the upper sash and holds it in place. Both corners or an gles oi the said upper glass can be fastened in the same way but in tact one brad for each glass suilices to hold the glass indefinitely.

In the manufacture the blank is struck iii-om a suitable piece oil sheet metal and then the ends oi? the body are bent back alike or to the same side and at substantially right angles and constitute the so-called flanges or wings I. Then it depends on the use made oi? the brads whether one or the other hecomes the inside.

The shoulders 5 on the ends oi the body 2 are oi such length as will suiliciently spread the flanges 1: to use the brad as seen in Fig. 3 and hold the driving point as nearly as possible in line with the grain of the wood into which it is driven, the spread of the flanges relatively as far apart. as shown by means of said shoulders enabling this important ell'cot to be obtained and which would not be possible with the requisite depth oi llango ii they came immediately at the base oil the point and which would necessarily narrow the brad to such short space between flanges that it would throw the point at such a decided angle across the grain oi the sash that it would be liable to split the sash. This occurs because the idle flange must rest on the glass while the other ilange is dropped down over the ed go of the glass.

What I claim is:

As a new article oi' manul'acture, a brad tor iastening glass in hot-bcd sashes having a V-shaped driving point and a body extending laterally from the base ot said point at both sides and providing shoulders at each side oi said base, and said body pro vided with flanges at its ends extending rearward at right an glcs to said body from the outer portions of said shoulders.

In testimony whereof I allix my signature in presence oi. two witnesses.
