Abstract: A bushing for retaining and supporting at least one tool, spindle or the like includes at least two component parts which are constructed to together define therebetween an insertion seat for receiving a particularly tool, spindle or the like. The parts are adjustably movable with respect to each other between a plurality of differently spaced positions, to thereby adjust the size of the insertion seat as a function of the size of the particular tool, spindle or the like to be received therein. The parts each have retaining devices for matingly engaging each other in each of the plurality of positions, and for thereby fixing the relative spacing between the parts and the size of the insertion seat at each of the plurality of positions.

Abstract: A support for housing and displaying tools adapted to be used on numerically controlled machines includes a plurality of bushings, each carrying one or more tool housing seats. The bushings are removably and interchangeably mounted in a rectangular metallic frame so that the support may carry a series of different or equal bushings according to the type and sizes of tools to be housed therein.

Abstract: A telescopic guide for metal drawers includes, on each of the opposite sides of a drawer, a pair of guideways, one secured to a piece of furniture and the other secured to the respective side of the drawer, and a rail-type intermediate element designed to slide on both of the guideways. Each intermediate element includes two single parallel rails designed to independently cooperate with the guideway of the piece of furniture and with the guideway of the drawer. Catches or stops are provided for the intermediate element to be pulled or pushed by the drawer.

Abstract: An assembly includes a dolly and a plurality of supports removably fitted at different levels within the dolly, for the housing, conveying and bringing forth of tools, particularly in the operation of numerically controlled machines. Secured to each of the supports are a plurality of cone-shaped bushes, wherein tools can be accommodated and retained. The supports are removably secured to the dolly, each in a selected of a plurality of positions.
