BELT-CNNECTOE.

Specification of Letters Patent.

Patented-Apr. 15,1913.

Application filed.v February 19, 1912. Serial No. 678,622.

To all whom t may concern Be it known that I, MYRON C. LISLE, a citizen of the United States, residing at Milwaukee, county of Milwaukee, and State of Wisconsin, have invented new and use ful Improvements in vBelt-Connectors, of which the following is a specification.

My invention relates t-o improvements in belt connectors. rlhe object of my invention is to provide a connector which will not open wholly or inV connector wire to spread is not due to ai bending of the metal in the hooked portions of the connector, but to a flexion in the middle portion of the back, and I have therefore devised means whereby the back of the connector constitutes a truss, which will not bend under any ordinary strains, and I find that connectors made in this manner will retain their shape throughout the hooked portions and at the inturned ends or points, the points remaining in clenching contact with the surface of the belt on the inner side.

In the drawings-Figure l is a longitudinal sectional view of the meeting end portions of a belt with my improved connector applied thereto, the section being drawn to a plane to wholly expose the connector. Fig. 2 is a cross sectional view drawn through the central portion of the connector.

Like parts are identified by the same reference characters in both views.

My improved connector is preferably formed of wire and constitutes a link having a back A, hook shaped end portions B, adapted to pass through apertures in the belt, and inturned end portions C adapted t-o clench or bear upon the inner surface of t-he belt adj acentv to the meeting ends. The back A is widened in a plane at right angles to the surface of the belt to which it is applied,

y and is also narrowed in the transverse plane,

55 the material composing the connector being flattened in a plane which includes the back A and the end portions C. The sides of the back A are preferably creased or indented 1n the middle portions, forming inner and Aouter ribs a and a connected together by a web a. The web a tapers to a. point near ,the ends of the back A, the ribs a and c converging and terminating in the hooked portions B, which are circular in cross section. The extremities of t-he inturned end portions C are preferably filed or ground olf, as shown at D, to avoid cutting edges which might otherwise tear the belt when the latter is crossed.

It is desirable that the hooked portions B should be circular in cross section, since they have less tendency to cut out the material composing the belt than if they' were flattened or pro-vided with squared angles. The back portion A of the connector has no tendency to cut the belt, however, and by flattening it in a plane perpendicular to the surface of the belt to which it is applied, an arch or truss is formed which possesses great rigidity. The strength of this portion is still further increased by indenting the central portion of each side to form a web a, thus providing a greater amount of stock in the ribs a and a for a given weight of material. This is a consideration of great importance to economy in manufacture, since the connectors can be most conveniently and cheaply formed from pieces of wire bent into the desired shapes and having the back pressed into the desired form from the original cylindrical form of the wire.

. I claim* 1. A belt connector formed integrally from a single piece of Wire provided with inturned hook shaped end portions and a back which is flattened transversely over the eX- tremities of the hooks and enlarged at right angles to the surface of the belt to form a truss.

2. A belt connector provided with inturned hook shaped end port-ions circular in cross section, and a back having a width in a plane perpendicular to the surface of the belt to which it is applied, greater than its transverse diameter and greater than the cross sectional dimensions of the'hook poi tions, the inner margin of the back being formed to bear upon the ends of the belt, I

provided with inturned hook shaped end portions, and having a flattened back in a plane which includes the inturned end portions, the outer and inner Walls of said back tapering from its central portion in the direction of the hook shaped end portions, and said hook shaped end portions having eX- tremities beveledin the direction of the belt.

1i. A belt connector comprising 'a back composed of a pair of ribs connect-ed by an integral central Web and which converge to- Ward the respective ends of the back, in combination With integral inturned hook shaped portions at therespective ends of the back.

5. A belt connector formed integrally from a single piece of Wire and having its back portion flattened in a plane perpendicular to the surface of the belt to Which the back is applied, said connector having hooks at its respective ends, With inturned extremities in substantial alinement opposite the flattened back portion.

In testimony whereof I affix my signature in the presence of two Witnesses. MYRON C. LISLE.
