Abstract
Abstract An outside elevator used for the purpose of hauling men and materials in and out of a multi-story building during construction or other periods depends solely for the support of its own weight and the payload upon attachments to temporary support frames wedged between floor and ceiling of one story of the building. The elevator supports a power hoist mechanism on the top of an open structure two or more stories in height which is raised into place alongside these temporary support frames on elevator guide rails spaced from the building wall by support brackets at each floor. When this hoist supporting structure is fastened to the building through the support frames, the hoist can then raise and lower the payload on a cage also riding on the guide rails up into the open structure to serve not only the lower stories of the building but those adjacent to the open structure itself. With this elevator in use on a building under construction, not only is the usual four-legged tower obviated, but added stories are easily served. Extension of the elevator upward with the rising structure is also simplified.
