A lock mechanism has a cylindrical housing with an axial bore therethrough, and a key-controlled core rotatable within the bore between locked and unlocked conditions and removable from and installable in the bore in the unlocked condition. The core has a plug at its rear end which is mateably engageable in a socket on the front face of a shifter, for rotating the shifter within the bore in response to rotation of the core, and thereby operating a latch member coupled to the shifter. A radial tab on the housing is receivable in an arcuate groove formed in the outer surface of the shifter for limiting rotation of the shifter to facilitate retention of the shifter in the single rotational orientation upon removal of the core from the housing. An O-ring on the shifter frictionally inhibits rotation thereof.

The latch mechanism includes a drawer pull at the front of the drawer. Under the top flange of the drawer pull is a channel in which a latch member is slidably movable from side to side. A hook is integral with one end of the latch member, which is spring loaded to its latched position. When it is desired to open the drawer, the user places his fingertips beneath the pull and against the latch member and moves the slide member to its unlatched position.

A molded plastic utility cart includes a one-piece hollow molded frame filled with a foamed plastic material, the frame being generally I-shaped in configuration and including an upstanding wall with a generally horizontal base at its lower end and a generally horizontal top at its upper end defining an open-top receptacle. A plastic cover is slidably mounted on the top for movement between a closed position covering the receptacle and an open position extending laterally from the top and uncovering the receptacle. The cover itself defines additional receptacle compartments. Accessory article supports may be mounted on any of the upstanding wall portion, the base or the top, and may be in the nature of additional receptacles, tool hangers or the like. A plurality of caster wheels are mounted on the underside of the base and handles are provided at both ends of the top.

A tool cabinet is formed without the use of fasteners or weldments by providing back and side panel sections in an integral unit having top and bottom flanges, and separate top and bottom panel sections having attachment flanges adapted to be interfitted with the flanges on the back and side panel unit to form an open-front housing. Three continuous loop frame members are spaced apart front-to-back inside the housing and are adhesively secured to the top, bottom and side panel sections and support drawer assemblies mounted in a front opening. A lock bar guide is adhesively secured to the back panel section and receives a lock bar which is inserted through a notch in the bottom panel section after the housing has been assembled. Adhesive or frictional interengagement may also be used to secure together the flanges of the panel sections. An internal framework comprising a single, wide loop frame member with spaced-apart ribs is also disclosed.

Adhesively bonded tool cabinet and method of assembly thereof

A tool cabinet has rollers depending from a bottom wall for rolling engagement with an underlying floor. A retractable step has depending legs and spring-loaded casters which support the step so that it can freely roll except when weight is placed on the step driving the legs into engagement with the floor. The step has a vertical slot in which is received a depending arm of an angle bracket which is fixed to a roller slide assembly mounted on the underside of the cabinet so that the step can be horizontally rolled between a stowed position beneath the cabinet and an extended position extending from beneath the cabinet and can move between raised and lowered positions when extended.

The open-end wrenching head includes two jaws and a throat interconnecting the jaws. The jaws include planar jaw driving surfaces each with a roughened region thereon adjacent to the throat and an unroughened region adjacent to the outermost end of the jaw driving surface, each of the roughened and unroughened regions being constructed and arranged to engage a portion of a selected side of a fastener. The throat may include either an arcuate surface or two planar throat driving surfaces. Each of the roughened regions has a coefficient of friction substantially greater than that of the unroughened regions and may be formed by deposition of an abrasive material by any of a number of processes or by deformation of the jaw driving surface by any of a number of processes.

A tool for rotatably driving a fastening member includes a hollow tubular shank closed at one end by a handle fixed thereto and having coupled to the other end thereof in communication therewith a socket for receiving an associated rotatable fastening member. A helical compression spring is disposed coaxially within the shank, having the inner end thereof embedded in a body of adhesive material and having the outer end thereof fixed to the keeper of a magnet disposed for magnetic engagement with a fastening member received in the socket. In assembly, the adhesive material is inserted in the shank in a fluid state, the inner end of the spring is immersed in the fluid, and the adhesive is then cured to a solid state.
