Abstract: A method of extending a reach of a material mover may include uncoupling and removing a first linkage that couples a work implement to an actuator on the material mover; uncoupling the work implement from one or more lifter arms; securing one or more extensions to each of the one or more lifter arms by (a) fastening, with a first fastener, an extension to a corresponding lifter arm, though a lifter-arm retention aperture, and (b) further securing the extension to the corresponding lifter arm with one or more additional fasteners adjacent the lifter-arm retention aperture and a top edge or bottom edge of an end of the corresponding lifter arm; coupling the work implement to the one or more extensions; and coupling a second linkage, which is longer than the first linkage, to the work implement and to the actuator.

Abstract: A lightweight, portable scaffold system has at least two support members which bear a platform. The support members have a Y-shaped base. Independently, adjustable legs attach to the arms of the Y and allow the support member to stand level on uneven ground. A support arm cantilevers from the stem of the Y. The support arm of each support member contacts a vertical surface and bears the platform. The scaffold structure is constructed of hollow stock to reduce its weight and can be dismantled and stored in a duffle bag.

Abstract: An adjustable leg support assembly that includes a cross brace slidably mounted on a center support and projecting laterally therefrom to opposed ends spaced from the center support. An upper clevis is slidably mounted on the center support above the cross brace. A pair of legs each have one end affixed to the upper clevis, a lower end and a center portion affixed to associated ends of the cross brace. An attachment arrangement is selectively mountable at the upper end of the center support for attachment of structure to be supported. The upper clevis may be adjustably affixed to the center support such that the attachment structure on the center support is adjustably positionable with respect to the lower ends of the legs.

Abstract: A work support device with adjustable length legs used to stabilize the work support on an uneven bearing surface, that is height adjustable, allowing the user to raise a supported work piece to a desired height, and that is levelable in that the user can adjust the work support to level the work piece being supported. Both the adjustable length legs and the height adjustable upper beam are self locking. Unlocking the height adjustable upper beam to allow downward movement is accomplished with finger pressure on a rod. Unlocking the adjustable length leg is accomplished with finger pressure on a lever. The self locking action occurs immediately upon releasing pressure on either the rod or the lever.

Abstract: Scaffold structure which is adapted to be positioned adjacent a wall and to engage a wall. The scaffold structure has a pair of legs which support a load support member. A brace is attached to the load support member and extends angularly therefrom. The brace has a portion which engages a wall so that the load support member is horizontal and the scaffold structure in a firm relationship with respect to the wall even though the brace is not attached to the wall.

Abstract: A support structure is disclosed for a scaffolding system. The support structure is collapsible and adjustable in height. The support structure includes a first rigid cross bar having a first and second pair of support legs disposed at both ends of the cross bar. The support legs of the pairs are hingedly connected to the first cross bar. First and second intermediate supports are connected to opposite ends of the first cross bar and extend downwardly therefrom between opposing support legs. Releasable brace means are provided for rigidly tying free ends of the intermediate supports to opposing legs of the support structure. A second rigid cross bar is provided as being sized to extend between the first and second intermediate support structures. A lock pin releasably secures first and second ends of the second cross bar to the first and second intermediate supports at spaced intervals along the lengths of the intermediate supports.

Abstract: A new sawhorse bracket for use with a rectangular cross-section cross-bar, usually of wood, is formed preferably by stamping and subsequent bending from a continuous strip of metal, the bracket comprising a central portion of truncated isosceles triangle shape so as to have two inclined edges, leg supporting portions extending at right angles to the central portion, return portions extending at right angles to the leg-supporting portions, and end portions which engage the sides of the cross-bar. The bracket is fastened to the cross-bar by screws passing through the central portion and a single relatively heavy bolt passing through the end members and the cross-bar. The legs are pivoted to the inclined leg-supporting portions and therefore move from a splayed support position to a stored position alongside the cross-bar to be stable when erected but occupying minimum space when stored.

Abstract: An improved foldable work stand and platform having an upper work support surface with wooden inserts therein to protect saws and the like from being damaged by accidental contact with the metal structure of the platform. The foldable work platform also includes improved structure for elevating the working surface and an adjustable stabilizer leg to maintain the work surface generally horizontal on uneven terrain. Lateral extensions of the work surface provide versatility in the work surface configuration and are easily secured in a selected orientation.

Abstract: A scaffold structure comprising a pair of leg frames and a support frame. The support frame includes a pair of posts vertically slidably received in the leg frames and means for locking the same thereto at selected elevations. The support frame includes telescopically engaged members whereby it can be extended or contracted and locked to provide a support of different lengths.
