. SECURING DEVICE.

Specification of Letters Patent.

Patented Sept. 19, 1905.

Application filed February 19, 1903- Serial No. 144,063.

To all w/wm zit may concern.-

Be it known that I, FERDINAND W. STARR, a citizen of the United States, residing at Springfield, county of Clark, State of Ohio, have invented a certain new and useful Improvement in Securing Devices; and I declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

This invention relates to securing devices, and has for its object an improved form of securing device that is intended to be used in place of the ordinary glaziers point, or more especially for securing backs in pictureframes and in all places where it is desired to drive a securing device along a flatsurface into the frame in which the fiat surface lies.

In the drawings several forms adapted to the several different places above named are shown.

Figure 1 is a side elevation. Fig. 2is aplan view. Fig. 3 is a perspective of one form of device. Fig. 4 shows a device like that shown in Fig. 3, differing from that in the way the edges are sharpened. Fig. 5 shows adevice having several points. Fig. 6 shows a device having a double system of points, but which is similarly applied. Fig. 7 shows a strip of the point shown in Fig. 3 partially but not wholly severed one from another. Fig. 8 shows a device like that shown in Fig. 5, except the flange or extension a is larger. Fig. 9 is a perspective of the multipointed device similar to that of Fig. 5.

The fastener is preferably made from sheet metal, which is preferably first bent to produce a bead running crosswise what will be the finished point or penetrating edges and with a projecting flange on each side of the bead. The projection on one side at least is cut into points, and the metal is cut into pieces, each of which has either a single, double, or multiple point. Both flanges may be cut into points, if desired. The opposing v faces of the metal within the cavity of the bead are brought close together, so that there is no tendency of the fastener to bend when force is applied to drive it into wood.

a indicates the flange at one side.

1) indicates the bead bent or struck up along the metal, and 0 indicates the points at one side of the bead b.

In the form shown in Figs. 1 to 4, inclusive, and in the form shown in Fig. 7v the points have a base at the bead which is equal in width to the length of the bead on a single point.

Where the device is formed with multipoints, the points are each made narrower at the base and a considerable part of the metal is cut out. Such multiple points are shown in Figs. 5, 6, 8, and 9. In Fig. 6, which is a double-pointed device cut so as to make it light, the points 0 and c are opposite each other, but may be staggered with the bead 1) between, so that either side may be inserted.

This fastening device is easily driven to place by placing a tool, like a flat nail-set or dull chisel, upon the flange a or rearward projection 0 with the end of it abutting against the bead b and striking or pushing the end of the tool. It is likewise easily removed or pulled by drawing, prying, or pushing on the bead b.

The method of making the devices herein described is simply what is now regarded an expeditious way. It may, however, be otherwise made, the principal novelty of the invention residing in the device having a penetrating point or points, a rearward projection, and a bead or rib intermediate between said-point and rearward projection, and the facility with which such a device may be used for the purpose mentioned.

I/Vhat I claim is 1. A sheet-metal fastening device, comprising a point, a flange, and a bead, the bead being between the point and the flange and having the opposing faces in the cavity of the bead brought into close engagement, sub stantially as described.

2. A sheet-metal fastening device having an entering-point, a rearward extension and a bead witht its walls in close engagement intermediate between the same for the purpose described.

3. A glaziers point, comprising a pointed body which has one side formed as a plane surface, and a lug which projects from the opposite side of the body and intermediately of its extremities.

4. A glaziers point, comprising a body projects from the opposite side of said body which has one side formed as a plane surface and intermediately of its extremities. 10 which has a plurality of points, and a lug In testimony whereof I sign this specifica- Which projects from the opposite side of the tion in the presence of two Witnesses. 5 body and intermediately of its extremities. FERDINAND W. STARR.

5. A glaziers point, comprising a pointed Witnessesz' body which has one side formed as a lane JACOB M. HARNER, surface, and'a lug Which is integral with and H. H. SCHMIDT.
