Abstract: A pipe coupler is disclosed for the repair of a damaged top rail of a cylindrical chain link fence pipe. The pipe coupler comprises a pipe coupler having a cylindrical body wall including a primary socket and a secondary socket. The primary socket and the secondary socket have a larger cylindrical diameter than the cylindrical top rail of the chain link fence for slidably engaging with the ends of the top rail portions. The pipe coupler has a socket door for covering a socket grove which prevents the separation of a replacement cylindrical rail portion or an existing cylindrical rail portion. A flexible strap and a clamp are used to keep the socket door closed.

Abstract: A lifting device is disclosed for elevating an object between a first elevation and a second elevation. The lifting device comprises a base frame, a load bearing frame coupled to the base frame, an elevation reducing frame coupled to the load bearing frame and an extension frame coupled to the elevation reducing frame. A mounting bracket is coupled to the base frame. The mounting bracket engages a rung of a ladder. A load winch is coupled to the load bearing frame and lifts the object and transferring the weight of the object to the ladder. The base frame, the load bearing frame and the elevation reducing frame define an object chamber for receiving the object in the object chamber and increasing the elevation of the object relative to the extension frame.
