JAMES B. CONRAD, OF SMI'IHS MILLS, PENSYLVANIA.

BELT-FASTENER.

SPECIFICATION forming part of Letters Patent No. 279,716, dated June 19, 1883.

Application filed December 2l, 1882.

1 To all whom, it may concern:V

' being had to the accompanying drawings, and

to letters or figures of reference marked thereon, which form a part of this specification.

Figure l of the drawings is a representation of this invention in a perspective view. Fig. 2 'is a plan View of the fastener, showing the outside. inside. Fig. 4 is alongitudinal section. Figs. 5 and 6 are details in perspective of the different parts.

This invention has relation to devices for fastening together the ends of bands and belts; and it consists in the construction and novel arrangement, in connection with two T- headed loop-bars, of a T- headed connecting-bar having between its. heads and middle portion lateral lugs designed to engage the slots of the loop-bars, all as hereinafter set forth.

In the annexed drawings, the letters va c designate the ends of a belt, or `of parts of a belt which are -to be connected. With the point of a knife are formed, in each end a, two series of longitudinal openings, b b', one series being nearer to the end edge of the belt than the other, and both series being parallel to said end edge.

To the inner set of openings or perforations, Z, are connected the loop-bars c. Each loopbar is formed with a Thead, cfat" its outer end to engage one of the perforations b, and

with a loop, e, at its other end to engage the connecting-bar. The loop-bar is long and nar- Fig. 3 is a plan view showing the.

row, and is adapted to pass edgewise through the slit b. W'hen turned iiatwise against the face of the strap or belt, the T- head engages said slit or opening crosswise. In this position the loop-bar is convex or curved to correspond with the curvature of the belt and the thickness thereof, as shown in the drawings. Each end of the belt is provided with a series of these loop -bars c connected to the outer series of perforations, and extending toward the end edge g of the belt. By means of the connecting-bars h the fastening is made. The

connecting-bar consists ofV a short strip of metal bent in convex form, and having at each end a T- head, k, and between said T- head and its middle portion lateral lugs I. By means of the T- heads the connecting-bar engages perforations b of the series next the end edges r/ of the strap, said perforations being so arranged that when the bar is in connection the end edges will be abutted, or nearly so. The connecting-bars are also passed through the loops of the loop-bars c and engage the saine by the intermediate lateral lugs, I. In this manner a double connection is effected between the belt ends and loop-bars, and a durable and flexible fastening is formed well suited for the belting of machinery.

In testimony whereof I affix my signature in presence of two witnesses.
