ABSTRACT:
A cable feeding and brake device for use in controllably lowering hanging cable with the aid of gravity through passage means between floors of a high-rise building wherein the device includes a housing supported by legs, the housing carrying a plurality of rollers defining a guideway for the cable between rollers disposed on opposite sides of the cable passing through the guideway, a manually rotatable hand wheel positively turns a pair of the rollers through a chain drive and a manual adjustment urges a roller on the opposite side of the cable between the spaced driven rollers to deflect the cable thereby providing a holding resistance against downward pulling of the cable through the housing guideway. The device is also provided with a manually operated brake which positively clamps and holds the cable in a desired fixed position.
