摘要： A baking and/or cooling rack having at least two shelves formed of wire. The shelves are connected by wire support legs such as at the outside corners of the shelves. The connection between each shelf and its attached support legs is provided by a spring pin. The spring pins form hinges which provide a friction force preventing free movement of the connected support legs with respect to the shelves, but which allows forced movement of the connected support legs with respect to the shelves, thereby allowing the rack to fold between an upright position and a knocked down position. A third shelf may be removably supported by the support legs between the first and second shelves.

摘要： A collapsible multi-level baking rack assembly includes a plurality of racks, at least one connector leg and at least one leg retainer. Each rack includes at least one horizontally projecting lug. Each connector leg defines a plurality of substantially horizontal, vertically spaced slots for removably receiving a lug of one of the racks to support and space apart the plurality of racks. The retainer leg mutually engages a lug of each rack and the connector leg to retain each lug in each slot of the connector leg.

摘要： A chuck assembly for a tool bit includes a spindle with a quick release mechanism and is adapted to prevent undesired axial retraction of the tool bit from the spindle. The tool bit includes a shank portion with a circumferential groove. A longitudinally extending bore is provided in the spindle for receiving the shank portion of the tool bit. The shank is retained in the bore by detent balls extending into the bore and against the circumferential groove. The balls are disposed around the shank in an opposing manner to help center the shank. Attempted axial extraction of the tool bit from the bore without release of the balls locks the balls against a retaining face and a biased locking shoulder preventing extraction of the tool bit from the bore.

摘要： The invention is an improvement to a chuck assembly of the type having a chuck hub with a longitudinally extending bore therein the longitudinally extending bore having a closed end, an open end, and a radially extending bit bore in communication with the longitudinally extending bore, and a bit ball movable in the ball bore between a first retracted position out of the longitudinally extending bore and a second engaged position partially in the longitudinally extending bore. The inventive improvement includes a shuttle slidably disposed in the longitudinally extending bore. The shuttle has a first longitudinally extending portion having a first lateral dimension and a second longitudinally extending portion having a second, smaller lateral dimension. The shuttle is movable longitudinally between a first release position and a second lock position. The inventive improvement also includes a compression spring urging the shuttle away from the closed end of the longitudinally extending bore, and a shuttle ball disposed in a radially extending shuttle ball bore in the chuck hub which is in communication with the longitudinally extending bore of the chuck hub. The shuttle ball is movable in the shuttle ball bore between a first retracted position where the shuttle ball contacts the first longitudinally extending portion of the shuttle and a second extended position where the shuttle ball contacts the second longitudinally extending portion of the shuttle.

摘要： A tool-bit holder has a hub, wherein the hub has a longitudinally extending axial bore for receiving a tool-bit therein, a detent ball radially projecting into the bore to selectively engage the tool-bit, and a circumferential ramp that is longitudinally moveable over the detent ball to cause radial movement thereof. A longitudinally moveable member extends through a slot in the hub and radially into the bore. The circumferential ramp is moveable as a function of longitudinal movement of the moveable member relative to the hub.

摘要： A tool-bit holder for receiving a tool-bit that automatically captures the tool-bit as it is inserted into the holder with a quick release mechanism to prevent axial withdrawal of the tool-bit from the holder. The tool-bit includes a shank portion with a circumferential groove. The tool-bit holder also includes a hub having a longitudinal bore for receiving the shank and a radial bore partially housing a detent ball used to capture the tool-bit shank at its circumferential groove within the tool-bit holder. A sleeve is axially slidably mounted relative to the hub and has a radial bore in communication with the radial bore of the hub for reception of the detent ball. The sleeve is axially biased by a spring and forces the detent ball against and along an inner ramp face fixed relative to the hub. The inner ramp face forces the detent ball radially inwardly and through the radial bore to seat in the circumferential groove of the tool-bit shank. Attempted axial extraction of the tool-bit from the longitudinal bore without releasing the detent ball locks the ball against the inner ramp face and prevents extraction of the tool-bit. The tool-bit is released when the bias force of the spring is relieved or countered by axially sliding the sleeve relative to the hub, so that the tool-bit can then be withdrawn from the hub.
