$PECIFIOATION forming part of Letters Patent No. 742,206, dated October 27, 1903. Application-filed February 16, 1903, Serial No. 143,724. (No model.)
To aZZ whom, it may concern.-
Be it known that I, HIRAM J. MAURER, a
citizen of the United States, residing at Birtion-but may be applied with an ordinary tion of the .rivet proper.' Fig. 2 is a bottom plan thereof. Fig. 3 is a side elevation of the punch or die. Fig. leis atop plan thereof. Fig. 5 is a sectional detail showing the application of my device to several sections of leather. Fig. 6 is a similar view showing the rivet in its final position, and Fig. 7-is a top plan of Fig. 6.
The object of my invention is to construct a rivet for leather, belts, canvas, or cloth of any description which can be applied without the use of special tools-such as leatherpunches, rivet-sets, or leversof any descriphammer or similar weight or tool.
A further object is to construct a rivet which will efiectively connect the parts to which it is applied, one which will be strong and durable, and one possessing further and other advantages, better apparent from a detailed description of the invention, which is is as follows:
Referring to the drawings, 1 represents the body portion of the rivet proper, the same having a terminal conical head 2, provided with a marginal flange 3. The die or bur 4, which is first driven into the material tobe riveted, terminates at one end in a series of converging cutting-prongs 5 and at the opposite end in a flange 6. The die is driven into the layers B of the material to be riveted, Fig. 5, the core 0 cut out thereby being forced out by inserting and driving the rivet into the die from the cutting end thereof. When the two sections are fully driven home, the projecting end of the rivet is burred over the flange 6, and should the thickness of the several layers be such as to cause the prongs 5 to project these will foldto conform to the conical surface of the head 2, and the operation is complete, Fig. 6. i that the rivets can be manipulated without any special riveting or setting tools, the rivet being applied or inserted in place with the use of an ordinary hammer or equivalent device.
Having described my invention, what I claim isr A rivet comprising an outer tube having a series of cutting-prongs at one end, a flange at the opposite end, and an inner tube or rivet proper having a terminal conical head, and a marginal flange for the latter, substantially as, and for the purpose set forth.
In testimony whereof I hereby affix my signature in presence of two witnesses.
