摘要： A ladder and platform assembly is described for stabily and releasably securing a ladder to a utility pole or the like. The ladder is attched at one end to a platform and includes a pair of generally parallel, spaced apart legs and a plurality of steps disposed between and interconnected between the legs. The platform includes a latch assembly for stabilizing the platform when the platform is disposed to rest against the pole, which has a given configuration. The platform has an opening of a configuration similar to the given configuration for receiving the pole. The latch assembly includes a latch pivotally mounted on the platform to move between a first, closed position wherein the latch retains the pole within the opening and a second, closed position wherein the latch permits the pole to be received within or removed from the opening. The latch has an extended portion. A spring is attached to the latch for normally biasing the latch to the second, open position. A self locking detent is disposed for engaging the extended position of the latch as it moves to the second, closed position and retaining the latch in a locked relationship therewith in the second, closed position. An actuable mechanisim is provided for releasing the detente from the locked relationship with the latch and permitting the latch to return to its first, open position under the influence of the biasing spring.

摘要： A spacer is disclosed for being inserted between adjacent curtains of electrostatic precipitators. Each spacer comprises a hanger adapted to engage the top-most edge or support bar of a curtain, for suspending the spacer therefrom, between the adjacent curtains. At least one hanging member or Tuck-bar is adapted to be suspended from the hanger, the number of Tuck-bars being dependent upon the vertical extent of the curtains. Each hanging member has first and second guides for engaging respective opposite stiffening members of adjacent curtains, whereby the hanging member is disposed substantially perpendicular therebetween.

摘要： A tool apparatus for applying a large closing force to an object is disclosed. The tool apparatus, capable of improving the efficiency and ease of effort required to crimp nuts onto bolts and to cut materials such as multi-strand cables, bars and the like, comprises first and second jaws, each having first and second portions. Each first portion has a linking end. A mechanism is provided for interconnecting the first and second jaws, and for providing a pivoting point for each of the first and second jaws. A hydraulic cylinder drives a rod linearly along a drive axis from a first position to a second position with a drive force. A scissor mechanism is provided for connecting the rod to the linking end of the first jaw and to the linking end of the second jaw, and for translating and multiplying the drive force to apply an opening force to each of the linking ends, whereby the first portions rotate from their closed position to their open position and the second portions rotate from their open position to their closed position to apply the closing force to the object.
