UNITED STATES PATENT OFFICE.

HENRY J. W'ELTEROTH AND JOHN H. WELTEROTH, OF WILLIAMSPORT,

PENNSYLVANIA.

METAL JOINT-'FASTEN ER.

SPECIFICATION forming part of Letters Patent No. 461,154, dated October 13, 1891.

Application filed August 30, 1890. Serial No. 363,523- (No model.)

To all whom it may concern:

Be it known that we, HENRY J. WVELTEROTH and J. H. WELTEROTH, citizens of the United States, residing at Williamsport, in the county of Lycoming and State of Pennsylvania, have invented certain new and useful Improvements in Metal Joint-Fasteners; and we do hereby 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 appertains to make and use the same. V

The special object of the invention is to make a box-fastener to connect the sides and ends by a tight joint.

Figure 1 of the drawings is a perspective view showing the simplest form of our boxfastener and embodying the principle of our invention; Fig. 2, an edge view, and Fig. 3 a view showing its application; Fig. 4, a vertical section to show the relative thickness of the upper and lower edge of the fastener.

In the drawings, A represents a plate of metal with the upper edge ablunt, so as to be conveniently struck with a hammer or other suitable tool, while the opposite edge a is sharp, so as to permit it to be driven into two pieces of board 13 0, about one-half in each, as shown in Fig. 3 of the drawings. From the edge a, to the edge a. extend the downwardlyinclined corrugations a converging toward each other from bottom to top. This forms awedge-space D, where the two middlecorrugations straddle the joint. This entirely prevents the fastener from drawing out from the influence of the weather upon the wood.

Any two pieces of wood may be thus held permanently together without fear that they will become loose, so as to be easily removed, or permit the box to be collapsed by a weight, pressure, or other force.

The length from a to a may be varied to suit the purpose for which they are intended, and the width from a to a may be greater or less, all being merely modifications of the simplest form illustrated in Fig. 1 of the drawings and embodying the same idea or principle. The corrugations may be more or less.

We are aware that hollow pointed nails have been corrugated on their sides, and also that j oint-fasteners have been made with parallel and diagonal corrugations; but

NVhat we claim as new is A sheet-metal joint-fastener having the two sets a a of corrugations inclined vertically to form the wedge-space D between them, as and for the purpose set forth.

In testimony whereof we aflix .our signatu res in presence of two witnesses.
