Abstract: An apparatus and method for forming an insert assembly on a printing press includes at least one processing mechanism for delivering at least one first ribbon defining an insert and at least one second ribbon defining at least a binding hanger, and a fastening arrangement for joining the first ribbon and the second ribbon to facilitate attachment of the insert to at least one signature during a perfect binding or saddle stitching operation.

Abstract: A heating device useful in ice fishing includes a housing having a retractable heater core which carries a self-contained heating substance and a reservoir filled with an evaporable liquid. The heating substance is cooperable with the reservoir to provide vapor and liquid droplets to prevent freezing of water within a hole cut in the ice and is further operable to furnish convectional heating of objects placed at the top of the housing.

Abstract: A conveyor roller and bearing arrangement rotatable about a pair of fixed stub axles lying between spaced side frame members includes a pair of self-aligning bearing assemblies in each end of the roller. Each bearing assembly includes an inner bearing race mounted on one of the stub axles, an outer bearing race rotatably mounted on the inner bearing race and an outer cushioning sleeve secured to the roller and outer bearing race for maintaining axial alignment between the inner and outer bearing races. A roller support assembly is positioned between the frame members to provide external support for the roller and cooperate with the bearing assemblies and stub axles to reduce the bending influence of the roller under loads.

Abstract: A frame supported conveyor useful in handling baggage includes inclined flights connected to movable link plates to form an endless chain assembly. A drive arrangement located beneath the conveyor engages and moves the endless chain assembly about a closed planar path. The drive arrangement is movably mounted on the frame between an operating position in engagement with the endless chain assembly and a servicing position out of engagement with and movable away from the endless chain assembly.

Abstract: A pusher mechanism supported on a framework for deflecting objects from a conveyor has a retractable pusher which is mounted for linear movement transversely across the conveyor. A paddle is pivotably attached at its midportion to an outer end of the pusher. A movable link is secured between the framework and an end of the paddle. Due to these paddle connections, controlled linear movement of the pusher will cause the paddle to articulate on the pusher from a rest position to an operating position at which an object is deflected from the conveyor and back to the rest position.

Abstract: A conveyor roller and bearing arrangement rotatable about a fixed axle lying between spaced side frame rails includes a pair of self-aligning bearing assemblies in each end of the roller. Each bearing assembly includes an inner bearing race fixed to the axle, an outer bearing race rotatably mounted on the inner bearing race and an outer cushioning sleeve secured to the roller and outer bearing race for maintaining axial alignment between the inner and outer bearing races.

Abstract: An accumulating conveyor having a control diaphragm for moving a roller driving member from a first position in disengagement with one or more conveyor rollers to a second position in driving engagement therewith. The driving member is supported by a flexible flange which is biased in a direction urging the driving member out of contact with the roller or rollers and additionally flexes in response to the control diaphragm.

Abstract: A plural speed planetary gear box has an input member and output member coupled together directly by a shiftable coupling sleeve or coupled together indirectly by a planetary gear set. The shift from direct to indirect coupling involves shifting the coupling sleeve out of direct coupling position between the input and output members to a different position in which the input member is coupled to one portion of the planetary gear set and the output member is coupled to another portion of the planetary gear set. A hydraulically actuated piston drives the coupling sleeve through a resiliently loaded lost motion isolator which applies a first force to the coupling sleeve for disengagement, and also applies a second force to the coupling sleeve to produce meshing engagement with the input member or with the planetary gear set element.

Abstract: A machine for pulling spikes from railroad ties including a pair of claws supported by the machine frame, one of the claws being positioned on one side of the rail and for pulling spikes on that side of the rail and the other of the claws being positioned on an opposite side of the rail and for pulling spikes on that side of the rail. Each of the claws including a lower end portion having a pair of spaced fingers extending toward the rail, and each claw being supported for movement from a retracted position to a position wherein the fingers of that claw are positionable under the head of a spike on opposite sides of the spike. The claws then move upwardly to pull spikes from the ties.
