    Abstract: A pair of ladder brackets held together by an elastic tie at one end of each having U-shaped clamps at the other ends for engaging the narrow sides of the side rails of a ladder when the brackets are fitted to the outer wide sides of the side rails. The elastic tie holds the U-shaped clamps against the inner wide sides of the rails. The brackets can be slid along the rails without interference from the rungs. The free ends of the brackets engage the roof of a building against which the ladder leans, to prevent the ladder from being displaced sideways. The brackets can be carried in a small package up a ladder by a user, and installed while the user is standing on the ladder.

  • Patent number: 4194592
    Abstract: A ladder stand-off is provided wherein a pair of parallel braces are transversely connected to a pair of extending arms so that a ladder will pass through the space between the braces and arms and that, when the ladder is in use with the stand-off, each of the braces will bear against an opposite side of the ladder to support the upper end of the ladder.

  • Patent number: 4189029
    Abstract: A scaffold device has two leg members having at their upper end spacers to space the legs away from a wall or other structure. Each leg has a support assembly for a platform upon which a worker may stand. The support assemblies comprise a pair of sleeves which can be adjustably secured to the legs, and a pair of rods each having one end pivotally secured relative to their corresponding sleeves, with the other rod ends having lock holes to permit the rod ends to be secured at a position to support the platform level with the ground for safe operation. A cross rail connects each of the legs and acts to maintain the relative position of the legs and also acts as a safety device to prevent workers from falling off the scaffold.

  • Patent number: 4164268
    Abstract: One or more elongated roller assemblies may be selectively mounted at a variety of positions along the inner edge of a scaffold platform. The inner and outer edges of the platform each include a series of correspondingly spaced apertures therethrough which receive the support rods or shafts of the roller assemblies. When the roller assemblies are emplaced the rollers lie between the inner edge of the platform and the vertical wall of the building along which the scaffolding is moving, and the mounting or support rods extend entirely through the platform and act as reinforcement of the assembly.

  • Patent number: 4125174
    Abstract: Scaffolding, for working in an area having relatively close spaced sidewalls, comprising generally T-shaped stackable members wherein the top of the T is adjustable outward to contact the sidewalls and limit sideway scaffolding movement. The T-shaped members can be stacked vertically, one atop the other, to provide different heights. A work platform, or staging, extends between the top of the uppermost T-shaped section and the top of a similar height spaced apart T-shaped section. Horizontal supports or stabilizers extend between the vertical columns which are built up from the T-shaped sections. The T-shaped sections are formed from metal tubing with adjustable portions, such as a threaded member, being connected at the ends of the top tubular member. When the scaffolding is erected, these adjustable members are adjusted out to engage the walls between which the scaffolding is utilized.

  • Patent number: 4083427
    Abstract: A pair of extension ladders are arranged in spaced, paralled vertically upright position. Diagonally extending cross braces extend between and are secured to the ladders to hold the ladders in upright position. A pair of wheels are provided on the bottom of one of the ladders to allow the scaffold to be easily moved by lifting up the other ladder. Hooks are provided on the ladders which fit into eyebolts on a building to hold the scaffold in position next to the building.

  • Patent number: 4078633
    Abstract: A staging includes sections that are easily transported or stored and in use are detachably joined to form vertical assemblies detachably interconnected by a railing with the assemblies connected to the building by braces. Each vertical assembly includes a support for platform-forming planks and a mechanism by which the platform may be raised or lowered by workmen supported thereby. The staging also includes sections connectable to the vertical assemblies to form roof-supported assemblies having brackets for platform-forming planks.

  • Patent number: 3998294
    Abstract: A connecting device is adapted to maintain an object, such as a scaffold assembly, at a selected spaced distance from a wall. The device includes a first tubular member having one end connected to the wall, and a second tubular member having one end connected to the object. The other ends of the first and second members are telescopically received in a third tubular member. The position of the first member may be longitudinally adjusted relative to the third member to provide a coarse adjustment of length. The second member is rotatably joined to the third member. A threaded engagement is provided between the first member and a stationary member mounted on the wall. A fine adjustment of length may be obtained by rotating the third member relative to the second member.
