Abstract: An adjustable cantilever rack containing means for accurately setting the elevational position of the outer end of the supporting arms. The cantilever rack includes a column of rectangular cross sectional shape, a base secured to the bottom of the column, a load supporting arm and a channel-shaped bracket secured to the inner end of the arm and adapted to fit around the column. Rows of circular spaced apertures formed in the column are adapted to receive bearing pins which are slidably insertable therethrough. An additional pair of apertures are formed in the flange portions of the bracket so that when aligned with the apertures in the column, a gap exists between the web portion of the bracket and the column. A pair of set screws are threadedly engaged with a corresponding pair of threaded apertures in the web portion of the bracket below the supporting arm for adjustably controlling the width of the gap and thereby adjustably controlling the elevational position of the outer end of the supporting arm.

Abstract: A cantilever storage rack having posts with vertically spaced rectangular apertures and arms having U-shaped brackets embracing the posts. Each bracket has two pairs of vertically spaced rectangular apertures so that two pins connect the bracket and post. The lower bracket apertures are spaced slightly rearwardly of the upper apertures in a direction away from the face of the column. The result is that the cantilever arm is supported by the pins with area contact but is held away from the column, thereby insuring accurate vertical arm location.

Abstract: An industrial storage rack construction which receives cassettes, that is, elongated racks for heavy materials, in vertically arranged relationship. The cassettes are to be inserted in and retrieved from the rack, and the invention pertains to the means for supporting the cassettes. This means comprises a series of rollers from front to rear of the rack at each level, supported by anti-friction bearings, and a rigid bar with a convex upper surface across the rear of the rack. The top of this bar is at a level slightly above the leve of the rollers. Each cassette is constructed with lower rails which ride on the rollers when the cassette is being inserted. The rearward ends of these rails will ride up on the rigid bar as insertion is completed so that the cassette will be frictionally locked in place while still being retrievable by the exertion of a relatively small withdrawing force.

Abstract: Two relatively thin sheets of metal are placed in stacked relation and bent so as to form two nested members, each having a pair of spaced parallel flanges, a central web portion at right angles to the flanges, and two inclined web portions connecting the central web portion with the flanges. The inner formed plate is then removed from the outer plate, reversed, and its flanges inserted within the flanges of the outer plate. The beam sections are then secured together.
