IMPROVEMENT IN LOCKING PLATE MEMBERS FOR USE IN SYSTEM FOR OVERHEAD SUPPORT OF WEIGHTED ARTICLES ABSTRACT OF THE DISCLOSURE An improved safety system for raising, lowering and supporting in an elevated or lowered position, a weighted arti- cle from an overhead support. The system includes a link chain passing over a safety pulling member, the link chain having one end permanently connected to the weighted article and the other end permanently connected to an attachment means positioned within reach of a person so that the person may pull the link chain downwardly to raise the weighted article to a desired elevation out of range of the person. The link chain has an improved locking member thereon which may be detachably attach- ed to and locked to the attachment means. The locking member, once installed on the link chain at the proper position, is tamper-proof and substantially break-proof. The weighted arti- cle may be a clothes basket, or other receptacle, or any arti- cle in which it is desired to selectively suspend overhead out of reach of a person and then lowered within range of a person.
