Patent number: 6082227Abstract: A novel system for visually coding tools as to their size comprises a maximum of two sets of differently colored bands which are placed on the surface of the tool. Each band of each color represents a portion of the size of the tool. Thus, when the number of bands of each color is counted, the size of the tool is indicated. Different colors are used to indicate metric tools versus English tools. Different color schemes may be used to represent the ownership of the tools.Type: GrantFiled: November 24, 1997Date of Patent: July 4, 2000Inventor: Arthur C. Vogel

Patent number: 6047618Abstract: Improved sockets for driving nuts and the like, the sockets having improved markings so that the proper size and type of each socket can be easily identified and selected, even under adverse conditions, and so that each socket can be readily returned to its proper location after use. This is accomplished by placing size markings on four (4) differing sides of a cylindrical socket, the size markings being spaced about 90.degree. apart. In addition, each of the sockets is color coded to facilitate reassembling the socket sets at the completion of work. In one example, colored plugs will be provided on each of the sockets either above or below the size markings. The sequence of colored plugs may repeat after three separate colors have been used if there is an obvious size difference between two sockets which are three sizes apart. In addition, the socket caddy is also be color coded.Type: GrantFiled: June 2, 1998Date of Patent: April 11, 2000Inventor: Kenneth H. Pieri

Patent number: 5862722Abstract: An adjustable wrench has a slotted body member and a handle threaded into a bore in a body member stem and protruding into one end of the slot. A movable jaw piece is rotatably mounted to the protruding handle end and slidable in the slot. A pair of angled fixed jaw faces is formed at the far end of the slot, while corresponding jaw faces are formed on the movable jaw piece. Relative rotation of the handle and body member causes relative advance or retraction of the movable jaw piece in the slot to adjust the spacing between the sets of jaw faces to fit the wrench to bolt heads or nuts of various sizes. The structural support afforded by the handle-movable jaw piece connection enables low cost construction and compact structure allowing greater accessibility to recessed bolt heads and nuts. A locking rod extends within the handle in some embodiments, with a locking knob at the remote handle able to be tightened to hold an adjusted position.Type: GrantFiled: September 20, 1996Date of Patent: January 26, 1999Inventor: Casimer J.

Patent number: 4947713Abstract: A molded elastomeric sleeve is carried by the rearward portion of a wrench socket. The sleeve has size indicia molded directly thereon (and may also be color coded) thereby facilitating a quick and convenient identification and selection of the respective socket from a tool box or kit. Suitable knurls on the outer diameter of the sleeve facilitate a manual rotation of the socket for seating a nut or bolt, prior to torquing with a conventional ratchet wrench. The knurls also prevent the socket from rolling, if placed sideways on a flat surface. Preferably, the rearward portion of the socket has a reduced diameter, thereby forming an annular shoulder between the forward and rearward portions of the socket, and the sleeve abuts against the annular shoulder. In an alternate embodiment, the sleeve is keyed to the socket, preferably by a "double dee" configuration, to prevent slippage or relative rotation between the socket and sleeve.Type: GrantFiled: December 4, 1985Date of Patent: August 14, 1990Assignee: Easco Hand Tools, Inc.Inventor: Robert L.
