tant @anni @fica een twv" Letters Patent No. 84,968, lated December 15, 1868 MPRO'VED BELT-HOOK The Schedule referred to in these Letters Patent and making part of the same` To all whom it may concern:

Be it known that I, CHARLES SARGENT", of Gran'- iteville, in the county of Middleser, and State of lidassa-A chusetts, have invented certain new and useful Improve' ments in Belt-Hooks or Belt-Connections, of which the following is a full, clear, and exacty description, reference being had to the accompanying drawings, making part of this specification, in which Figure 1 represents a portion of a machine-belt, with my improvements applied to the outside thereof;

Figure 2, an edge view; and Figure 3, a longitudinalsectiional elevation. Figures 4 and 5 are inner side elevations of my belt connections detached;

Figures 6 and 7 are end elevations of figs. 4 and 5; and

Figures 8 and?) are edge views of the same. Figure l0 represents a double-belt connection, made according to my improvement, that is, having two rows of eonnecting-pointsfor each end of the belt.

, This invention relates to a new and improved device for connecting the ends of machine-belts; and

It consists in a novel construction ofthe implement, and in the peculiar method of forming the connectingpoints, which pass through the substance -of thebelt and hold the ends together.

The object of this invention is to furnish a simple and very eihcent belt-connection, which can be easily applied, and so cheap that a new one can be afforded whenever the shortening or other alteration of the belt requires the removal'of the implement.

In my said invention, the connecting-points c are formed by punching or cutting them from the sheetmetal of which the implement is made, two sides only of each point being c'nt or punched through the plate, and each point bent round or outward to a right angle with the surface of the plate. Each of the points may be thus bent'by or in the punching-operation, the punch being bevelled from the point back to the heel, and a straight back to pass through the opening, and thus bend each point round to the desired position.

These connecting-points may be pointed or bevelled on one or both of theirsides, as shown in figs. 2, 3, 6,

and 7, or they may be driven through the substance Y of the belt, as they are when first formed, but in either case such points should be Well clinched on or upon the substance of the belt, so as to prevent the possibility of their drawing out when the belt moves rapidly over a pulley rotating at a high velocity, whereas, if the points were not clinched, the swift motion and centrifugal action would be liable to dislodge the connectingdevice, liberate one or both ends of the belt, and do great injury.

ACare should be observed, in punching or forming the connecting-points c, to punch or cut them in the direction of the grain of the metal, that is, lengthwise with the grain or libres of the metal, which are drawn or yelongated in the process of rolling, as rolled metal is much tougher and stronger lengthwise than cros'swise,

and the points thus formed will be very strong and tough, and will not break in bending, the lengthwise direction of the grain or libres being in thev direction of or parallel with the length of the belt, when applied as shown in iig. 1. Where more than ordinary strain comes on a Wide belt, a longer plate may be employed, with two or more rows of points to connect with each end of the belt, -as shown' in iig. 10, buty for all ordinary belts, I find that one row of points passing through the belt, and well clinched, will holdto break or tear strong leather. If made of good, tough metal, and the points punched in the right direction, as clearly described, these belt? connections may be several times attached and detached by clinching and unclinching the tough points,

which will bend easily several `times without breaking;

but, in order to save time, unless quite at leisure, I

' generally cut the belt closeto the edges of the connection, and then drive in a new one, which costs much less than the time required to remove the simplest belt-r connection I have ever seen before.

The connecting-points c may be cut or punched, and

bent round from the two edges, as shown in the plate H, in gs. 1, 2, 3; 4, 6, and 8, or such points may be formed by punching them from the substance of the metal, at a suitable distance from the edges, as shown in the plate k, in figs. 1, 2, 3, 5, 7, 9, and 10, butI prefer the latter, as the overlapping edges of the plate beyond the points are drawn closely on to the outside of the belt wheuthe points are clinched down, and their holding-action 4is thus materially increased.

I do not claim a belt-connection made' of cast-metal, points cast in one with the cast plate, such points being set at an angle, to be driven' into the belt; nor do I claim metal hooks or studs for\connecting the ends of belts, or for attaching straps or loops to boot-tops, suchl devices being old and well known; but

What I do claim, and desire to secure by Letters Patent, is-
