发明名称 Repair kit
摘要 In a repair kit for a broken rake arm in an automatic bowling pin setting machine, an elongated rigid sleeve is slipped over the rake arm such that the sleeve straddles the break. A fastener is threaded through the wall of the sleeve and grippingly bears against the outside surface of the rake arm. The sleeve is provided with a rigid strap that extends past the end of the sleeve in order to permit the accomodation of one end of a spring thereto. In one embodiment a right and left hand kit is required for the right and left hand rake arms of the bowling pin setting machine. Two other embodiments provide repair kits that are selectively useable as either a right hand kit or a left hand kit.
