ABSTRACT:
A new and improved emergency drive belt apparatus includes a flexible belt member, a first connector assembly attached to the first end of the belt member, a second connector assembly attached to the second end of the belt member, and a locking member capable of being positioned over the first connector assembly and the second connector assembly for locking the connector assemblies together to form the belt member into a continuous loop. The first and second connector assemblies have respective teeth. When the respective connector assemblies are connected together, the respective teeth are meshed together, and the locking member is in its locking position. The first connector assembly may further include a releasable assembly for selectively clamping the first end of the belt member in, or releasing the first end from, the first connector assembly. In the releasable assembly, a screw-controlled clamping plate may also include a cutting element for nicking or cutting off a portion of the belt member when the clamping plate is screwed onto the first end of the belt member. A plurality of first threads may be located on the first connector assembly, a plurality of second threads may be located on the second connector assembly, and a third threaded portion may be located on an interior surface of the locking member. The locking member is installed on the first and second connector assemblies by rotating the third threaded portion onto the first and second threaded portions so that the belt member forms a continuous loop.
