Abstract: A window scaffolding system including a pair of main support frames. The pair of main support frames are oriented in a side by side relationship for supporting planks of wood on upper and lower ends thereof. A pair of L-shaped window engagement members couple with the pair of main supports for securement to a window opening. A supplemental safety bar is provided having a generally elongated and planar configuration. The safety bar has a pair of pads disposed on opposing ends thereof and a central pad disposed on a central portion thereof. A bolt extends through the central portion and the central pad for securement to the window engagement members to preclude the system from disengaging the window opening.
Abstract: A window mounted temporary working platform which is totally assembled by one user from inside the window being repaired, maintained, or washed. The device provides a working platform at an elevation below the outer window sill with two side rails, an outer rail and a working platform which is supported without permanent installation on the building being serviced. The device is adjustable in width to accommodate a wide variety of window widths and is configured to provide for window with outer storm windows and window installation where the area below the inner sill is unavailable for platform support or connection due to of a heater or radiator.
Abstract: An improved portable window perch is easily assembled to allow a user to stand on a perch outside the window of a building structure. The perch is supported by a scaffold placed up against the inside wall surrounding a window. The scaffold has two vertical bars displaced from one another and which can be folded in half through the use of hinges on each of the two vertical bars. The vertical bars are displaced from one another with a cross member between them. Also, at the top of the two vertical bars is an upper horizontal bar, while at the bottom there is a lower horizontal bar. The two horizontal bars have padding thereon so as to prevent damage to the wall. The perch has two arms extended through the window, connected to a platform at one end, suspended outside the window, and a clamp at the other, connected to the cross member with the scaffold erected up against the inside wall, so that the perch is securely and safely supported outside the window.
Abstract: A deep water rescue platform incorporating a support frame with a pair of hanger arms for engagement with the side of a pool which are telescopingly adjustable with the frame, a pair of wheels attached to the bottom of the support frame for transportation and stabilizing engagement with the wall of the pool, and a platform hingedly attached to the lower end of the frame which folds into the plane of the frame during storage and a locking means for retaining the platform in its extended position.
Abstract: A hook device for hanging outside of a building window opening for supporting one end of a scaffold plank, the device being shaped with a hook at one end and a loop at its other end and also including a steadying cross brace fitted with bolts to abut the building wall face.
Abstract: A window bracket is constructed to be supported on a window sill and the walls beneath the sill of an open window and further constructed to hold a safety scaffold to permit work on the exterior of the building, either on the windows or the area between windows. It may be used in pairs to hold a scaffold or in greater numbers where the scaffold is longer and extends over a greater area of the building exterior. It is rigidly constructed by welding of steel or aluminum alloy for rapid installation through open windows and is equipped with safety railings and reinforcing brackets to insure complete safety of workmen working on the outside of the building, such as repairing the exterior wall, painting or washing or repairing the windows from the exterior of the building.
Abstract: There is disclosed a window perch so that access to the outside of a sash window may be had even though the window may be considerably above the ground. The perch does not depend on ground support, but on the contrary depends on the wall area located immediately below the window sill. The perch comprises a clamping arrangement that clamps to the stated wall area. Suitable bracket means extend normally to the outer wall portion of the stated wall area which carry a planar member upon which a workman may stand or may be seated. A safety railing is provided vertically displaced from the planar member which is suitably affixed to the planar member and the stated clamping arrangement. The perch is constructed in a manner so that it may be conveniently collapsed so that it may be more easily positioned and retrieved through the sash window and may be stored when not in use.

Abstract: A scaffolding device comprising a pair of units each having spaced vertical suspension members, a top rail member and a bottom cross member joined together, the top rail members extending forwardly of the adjacent vertical suspension members and telescopically receiving adjustable L-shaped arms for embracing a windowsill. Bumpers extend from the vertical suspension members nearest the building wall and engage the latter for lateral stability purposes. A platform is pivotally connected to the cross member of one unit and lies across the cross member of the other unit. The units are interconnected by a collapsible gate and a chain, and the chain also connects to the platform for assisting in the raising of the platform during removal of the device from a window opening.
Abstract: An erectable and transportable scaffold cage adapted to be engaged on and supported on a support beam comprises front and rear frame structures which are pivotally interconnected by means of parallel side braces which are connected between the frame structures. A reinforcing frame is pivotally connected to the lower ends of each of the front and rear frames and the front frame is pivotal outwardly from the rear structure to form a cage within the front and rear structures and the side braces having a floor formed by a scaffold plate which is supported on the reinforcing frame. The plate has upright bottom edges which fit flush against the insides of an angle member forming the sides of the front frame structure so that it facilitates the holding of the structure in an erected cage forming position. A flexible member such as a chain is connected between the upper ends of each side of the front structure to the upper ends of each side of the rear structure.
