Abstract
A toothed belt connector for making an endless belt has two leaves, adapted to be connected to each other by knuckles along one or more teeth. Each knuckle has at least one hole extending through tooth portions so that when the holes are in registry, a pin can be extended through the holes to connect the leaves at the teeth. The leaves can be adjoined to the ends of a belt to make the belt endless. The tip end of each knuckle can be beveled or it can have a stepped finger that fits into a cutout on the opposite leaf to keep the end of the knuckle from protruding as the belt wraps around a sprocket.
Claims20
A belt connector for connecting two ends of a belt segment to make an endless belt, wherein the belt connector comprises two leaves, each leaf having a flat side, one of the leaves having at least two knuckles and the other leaf having at least one knuckle, all knuckles having a tip end and a hole extending through the knuckle, each leaf having an end opposite the tip ends that is adapted to be secured to a belt segment, and a pin adapted to extend through the holes of the knuckles when the holes are in registry to connect the leaves to each other, characterized by the tip end of each knuckle having an inside edge that is beveled from the plane of the flat side whereby when the belt connecter is installed on a belt segment with the leaves connected to each other and when the knuckles are urged around a sprocket, the beveled tip edges will tend to align with the flat side of the opposite leaf to minimize an obstructing discontinuity at the tip end of the knuckles.
A belt connector for connecting two ends of a belt segment to make an endless belt, wherein the belt connector comprises two leaves, each leaf having a flat side, one of the leaves having at least two knuckles and the other leaf having at least one knuckle, all knuckles having a tip end and hole extending through the knuckle, each leaf having a butt end opposite the tip ends and adapted to be secured to a belt segment, and a pin adapted to extend through the holes of the knuckles when the holes are in registry to connect the leaves to each other, characterized by each tip end having a stepped finger extending therefrom with its upper surface stepped below the surface of the flat side, and each leaf having a cutout adjacent to the knuckles to receive the stepped finger with the upper surface of the belt broken only between adjacent knuckles and the lower surface of the belt broken only between the finger and the corresponding cutouts, whereby the tendency of the leaves to pivot about the pin is inhibited by each stepped finger abutting its corresponding cutout.
A method of making a belt connector comprising the steps of:
- providing two leaves, each leaf being flat on one side and having three teeth on the other side, each of two teeth having a hole extending therethrough;
- beveling an edge of each leaf from the flat side to form beveled edges;
- and
- cutting each leaf to form at least two knuckles in one leaf and one knuckle in the other leaf, each knuckle having a toothwith a hole through it and a beveled edge.
