Abstract: A device which is easily attached to the stiles of any ladder. This highly reliable device creates a steadfast ladder, removing the fear of the ladder flipping over or slipping out from under. This device is created in such a manner as to be attached to any ladder and also having a clearance to allow for any shoes attached or to be attached to the ladder's base. Ground penetration is easily achieved by the slike's ability to rotate. The design of the device allows ground penetration to any depth, making allowances for obstructions. Safety is achieved by the device's ability to stabilize the ladder's lower end. The handle lies flat against the ladder's stiles creating a self-contained unit that is out of the way when not in use.

Abstract: An improved ladder leg extender and leveler assembly including a frame structure which can be fixed in flush face-to-face relation to a ladder leg side so as to straddle rung fastener protrusions on the ladder leg side, thus avoiding bending stresses, the arrangement permitting quick and efficient assembly.

Abstract: A device for leveling a metal ladder comprising a mounting bracket which can be attached to the outside web of a ladder side rail, a threaded shaft embodied with a handle at its upper distal end and a convex semi-shperical head at its lower distal end which is sized to operate within a threaded bore hole in the distal member of said mounting bracket in order to provide means to raise or lower a pivotable ladder foot embodied with a concave semi-spherical surface within the raised center portion of said foot in order to provide a pivoting means for said foot with respect to said threaded shaft.

Abstract: This ladder is designed to clamp to sign posts for workman safety. Primarily, it consists of a pair of stepped legs with a hinged shelf at the top having a clamp that clamps to a sign post. A second clamp is also provided below and is secured to arms attached to the legs, and a pair of extension rods are provided on the legs for stabilily of the legs on sloping ground surfaces.

Abstract: A load leveling device for a ladder in the form of a compensator boot which slips onto a lower end of one of the legs of the ladder. The boot includes a vertically elongated block of homogeneous, molded plastic or rubber material and a vertically extending socket in the block opening in the upper end face of the block. The socket has cross-sectional dimensions sized to allow the lower end of the leg of the ladder to slide into the socket and has a blind lower end spaced vertically from the lower end face of the block by a distance compensating for the angle of the associated roof surface.

Abstract: A trestle ladder includes adjustable leg extensions to accommodate uneven and irregular surfaces while maintaining the ladder in proper vertical and horizontal orientation. A binding clamp is employed to retain the extension in the desired position and auxiliary rungs are provided for use when the extension of the legs is sufficient to require them.

Abstract: A ladder attachment for securement to a ladder leg which can function as a ladder standoff, ladder leg extension or roof ridge hook. The ladder standoff arrangement permits the ladder to be supported a predetermined distance from a wall, enables the ladder to be used as a scaffold, or provides a support for a work table or sawhorse.The attachment comprises a channel having an adjustable web and sidewalls with a reversible angle secured to one sidewall which cooperates with biasing means passing through the channel web and a ladder stile to frictionally lock an elongated member passing through holes formed in the sidewalls as a standoff or roof ridge hook or to frictionally lock an elongated member adjacent a ladder leg as an extension thereof.

Abstract: A telescopic scaffold comprising opposed pairs of elongated support legs each received in adjustable sleeve members securable at a predetermined location therealong. Arresting means is provided to interlock each sleeve member with its associated leg at a predetermined location therealong. An adjustable bracing end support structure is adjustably securable between each adjustable sleeve member of each pair of legs to secure each leg of the pairs of legs at a desired inclined angle to each other and at a desired spacing therebetween. A tubular support member is secured to each of the adjustable sleeve members and extends transverse to the longitudinal axis of the sleeve member and the end bracing. An intermediate horizontal support member is telescopically securable between opposed tubular members of the opposed pairs of support legs to constitute adjustable elongated side supports.

Abstract: A ladder extension device for enabling a ladder to stand upright upon uneven or inclined surfaces is disclosed which is composed of a pair of overlapping L-shaped side members secured about a ladder leg by bolts or other means.

Abstract: A ladder extension device for enabling a ladder to stand upright upon uneven or inclined surfaces is disclosed which is composed of a pair of diametrically opposed side members, preferably L-shaped, connected by hinges and secured about a ladder leg by bolts or other means.

Abstract: An extensible cargo brace for extending between and maintaining firm contact with opposite walls of a cargo vehicle. A pair of spaced inner rails is slidably, telescopically mounted within a pair of spaced outer rails with a plurality of rungs extending transversely between the rails of each pair. Tension springs are mounted within the outer rails and engageable with the inner rails normally biasing the inner rails into retracted position within the outer rails. A detent rack bar extends between adjacent rungs of the inner and outer rails and is fixed with respect to one pair of the rails and movable with respect to the other pair of rails. Lever actuated ratchet means is mounted on the other pair of rails and engages the detent rack for positively expanding the rails outwardly into engagement with the vehicle walls when a directional control toggle of the lever-ratchet means is in an advance position.
