  • Patent number: 5161792
    Abstract: A machine for converting a group of marginally registered signatures into a shingled stream which is fed to the hopper of a binding machine includes a main frame and several conveyors located in succession along the frame. The first is a feed conveyor having driven side belts which are arranged to allow one's hand to move along the conveyor and install stacks of signatures with the signatures being in an edge standing condition on the feed conveyor. Next comes a spreading conveyor which separates the signatures as they move in the edge standing condition between side belts which impart a slight bow to the signatures. Constricting gates exist between the feed and spreading conveyors and they sense the force with which the signatures are introduced into the feed conveyor. Then comes a lifting conveyor which lifts the signatures from the spreading conveyor in a shingled condition.

  • Patent number: 5137296
    Abstract: A power operated apparatus for permitting repositioning adjustments of a bogie position in its support of a trailer for enabling changes in the axle loading of the bogie by shifting the bogie forward or rearward on the trailer to meet highway axle loading requirements. The repositioning adjustments are selected through a power hook-up on the trailer and bogie through a system of switches to indicate whether the bogie is securely interlocked on the trailer and whether the bogie brakes are set and the pin connections to the trailer slider are retracted to allow tractor shift of the trailer while the bogie is held stationary by the application of the brakes. The power hook-up includes manual selection of the distance a bogie-trailer shift needs to be made in combination with a system of preselection of the distance in association with bogie brake application and indication of the condition of interlock or release of the pins relative to the trailer slider.

  • Patent number: 5129744
    Abstract: A seal for a roll neck bearing has a two interlocked components - a rotating component fitted to the inner race of the bearing and a stationary component fitted to the outer race. The rotating component includes a shield which fits around the end of the inner race, and, while it establishes a static barrier along the inner race, it can float or be displaced axially on the inner race. The stationary component has a seal case which fits snugly in a bore that opens out of the end of the outer race, it being trapped in that bore by a chock into which the bearing fits. Both the shield and case have axial walls and radial walls, and at the ends of their radial walls carry elastomeric seal elements. The seal element of the shield contacts the axial wall of the seal case, whereas the seal element of the seal case contacts the axial wall of the shield and further establishes a labyrinth along the shield.

  • Patent number: 5125156
    Abstract: The indirectly mounted tapered roller bearings which support a pinion shaft in a differential housing are set by turning a nut at the end of the shaft down to reduce the spacing between the cones of the two bearings. Initially, the bearings exist in end play, and as the end play diminishes, the torque transmitted through the bearings from the rotating shaft to the housing is monitored. When the transmitted torque increase, signifying that the bearings have entered preload, the nut is rotated still further, through a prescribed angle relative to the shaft. Thus, the preload in the bearings is set to be a prescribed dimensional magnitude. The bearings may also be set to a prescribed condition of end play by rotating the nut in the opposite direction when the transmitted torque increases.

  • Patent number: 5121998
    Abstract: A bearing assembly monitors angular velocity about its axis of rotation. The bearing assembly includes an outer race having a pair of tapered raceways presented inwardly, and two inner races in the form of cones, each having a tapered raceway presented outwardly toward one of the raceways of the outer race. The raceway of each cone lies between a thrust rib and end rib at the ends of the cone and tapers downwardly toward the end rib, all such that an undercut exists at the small end of the raceway where the end rib projects beyond it. The bearing assembly also has tapered rollers organized into two rows which are located between the opposed raceways of the outer race and the two cones. The cones abut at their end ribs, and the end ribs of the two cones carry a target wheel in the space between the two rows of rollers.

  • Patent number: 5114281
    Abstract: A machine for blowing loose thermal insulation into cavities in the walls, ceilings, and floors of buildings is contained within a smooth box-like housing that is easily moved about within a house on its own wheels and is easily transported to and from a job site. The housing encloses an equipment cavity and has a hopper located above the equipment cavity, but the hopper, into which the loose insulation is placed, is octagonal so that corner channels exist within the housing between the sides of the hopper and the corners of the housing. The equipment cavity at the bottom of the housing contains a motor which rotates an agitating wheel in the hopper, and that wheel has flexible tips that sweep the loose insulation over the floor of the hopper and into a feed hole in that floor. A grate extends through the hopper above the wheel to prevent access to the wheel in the bottom of the hopper.
