ABSTRACT:
Tip and adapter assemblies are normally utilized to provide an arrangement in which the tip can be readily removed from the adapter. It is normally advantageous to have a simple construction that allows the tip to be mounted on the adapter with the least amount of effort and likewise to have the ability to remove the tip from the adapter in like manner. In the subject arrangement, the tooth defines a socket which is adapted for mating contact with a nose portion of an adapter. The socket has a generally circular load transferring surface located adjacent an opening thereof. A plurality of clearance slots are provided angularly spaced around the circumference of the generally circular load transferring surface. A generally rectangular load transferring pocket is located in the socket adjacent a bottom surface thereof and has clearance reliefs defined thereon. A relief cavity is located in the socket between the generally circular bond transferring surface and the generally rectangular load transferring pocket. The relief cavity in conjunction with the clearance slots and the clearance reliefs enable the tooth to be mounted on the adapter that has four raised helical threads disposed thereon without having to rotate the tooth during assembly or disassembly thereof.
