BELT-FASTEN ER.

SPECIFICATION forming part of Letters Patent No. 435,949, dated. September 9, 1890.

Application filed December 30, 1889- Serial No. 335,384- (No model.)

To all whom it may concern.-

Be it known that I, LIZZIE T. POTTER, of the city and county of Hartford, and State of Connecticut, have invented certain new and useful Improvements in Belt-Fasteners, which improvements are described in the following specification and are illustrated by the accompanying drawings.

My invention belongs to that class of beltfasteners in which the body of the belt-fastener consists of a metallic plate, and is provided with teeth which project from one side of such plate and are adapted to pierce and clinch the belt.

The object of my invention is to prevent the teeth from being stripped or broken from the plate of the fastener, and at the same time to provide means whereby the teeth may advantageously be entered through the belt and clinched. To accomplish these results I use double-tipped teeth of peculiar form.

The best manner in which I have contemplated applying the principle of my invention is shown in said drawings, in Which- Figure 1 is a perspective view of a piece of belting provided with a belt-fastener which is constructed in accordance with my invention. Figs. 2 and 3 are a side view and top View, respectively, of a single tooth projecting from a portion of the plate.

In the views the numeral 1 denotes a flat rectangular metallic plate, constituting the body of the fastener and varying in size according to the size and strength of the belt 6, a

to which the fastener is to be applied. This plate is armed with teeth 2, which are formed integrally therewith, and project therefrom in convenient locations, as seen in Fig. 1. The form of these teeth is easily observed from the drawings. Each tooth, separately considered, is a flat plate, whose width lies in the direction of the length of the belt. The tooth is widest at the base or junction with plate 1, and tapers upward, as seen in Fig.

2, to two tips 3 and 4, which are separated from each other at the top, but have a common base 5. The height of base 5 measured from plate 1 to the point of bifurcation is preferably slightly less than half the entire height of the tooth. The inner edges of tips 3 and 4 of each tooth are beveled in opposite directions, like the adjacent edges of two saw-teeth. V

This belt-fastener is applied to the belt by hammering the belt onto teeth 2 in the usual position. As tooth 2 enters the belt its tips 3 and 4 are bent over in opposite directions, convenient for clinching, and are then hammered down and clinched in the usual manner, as seen in the middle section of Fig. 1. By this mode of operation each tooth is held in the belt by two tips, which lie clinched in opposite directions. At the same time the peculiar form of the tooth, particularly its great width of base, disposed as above de scribed in the direction of the length of the belt, prevents the tooth from being stripped or broken from the body of the fastener when subjected to the strains of use.

Such being the construction and operation of my invention, I claim- A metallic belt-fastener consisting of a plate provided with flat tapering teeth, each of which has two saw-tooth tips which are united with said plate by means of a common base or body of the tooth, and having the interior slanting edge of either tip and the adjacent interior slanting edge of the other sharpened in opposite directions and separated from each other by a V-notch which is located obliquely across the top of the tooth, substantially as and for the purpose specified.

In testimony whereof I have hereunto set my name in the presenceof two witnesses.

LIZZIE '1. POTTER.
