Abstract: A swing saw for cutting logs to length prior to cutting into lumber or plywood veneer is provided with a rotary arbor shaft coupled to a secondary drive shaft through a drive chain, the secondary drive shaft being coupled to an electric drive motor through drive belts. The secondary drive shaft is supported on laterally spaced bearings which, in turn, are maintained parallel by adjustment screws mounting rotatable sprockets which are coupled together through a secondary chain by which adjustable rotation of one of the sprockets effects simultaneous adjustable rotation of the other sprocket to precisely the same degree and direction. The adjustment screws thus are moved longitudinally in the same direction and precisely the same distance, and therefore the axis of the secondary drive shaft is maintained precisely parallel to the axis of the arbor shaft. The secondary drive shaft is secured by clamp plates when adjusted. Both shafts are mounted on a hollow housing in which the drive chain is contained.

Mounting means is provided for mounting the support means on a gateway post. The mounting means includes at least one elongate binding member for extending from the support means and about gateway post. A tensioning unit acts between the binding member and the gateway post in order to tension the binding member about the post and so secure the support means in position on the gateway post.

Abstract: An electric motor furnished with an end flange for its attachment to the wall of a bracket or the like, includes a belt tensioning contrivance incorporated in the flange. A circular projection the center of which is parallel and eccentrically positioned to the shaft of the motor protrudes out of the end face of the flange and engages with a circular perforation of corresponding size in the bracket wall.

Abstract: A mechanical drive mechanism of the endless belt and pulley type having an improved belt tensioning arrangement. The shaft of the machine being driven (or that of the driving member itself) is eccentrically journaled with respect to its cylindrical bearing hub and a rigid arm having a first bore therethrough is disposed with the hub of the machine centered in that first bore. Located at the opposed end of the rigid arm is a parallel bore in which the other drive or driven shaft is journaled. Because of the eccentricity between the first shaft and its hub, as the arm is rotated about the hub as a center, the distance between the centers of the driving and driven shafts is increased or decreased, depending upon the direction of rotation of the rigid arm. As such, the tension of the endless belt coupling the drive and driven pulleys can be varied.

Abstract: A method and apparatus for making packets of rotor or stator sheets for electrical machinery. At a certain station to which a preselected number of sheets are delivered, the sheets are both aligned and joined together. Aligning is effected by an aligning device which includes aligning pins which move into openings in the sheets. While the sheets are still at the aligning station, joining means effect joining together of the sheets. The joining means may include a piston pressed into the opening in the sheets and/or a device for welding the sheets together. At a packet receiving station before the aligning and joining station relatively high stacks of sheets are placed into magazine baskets suspended from a central turntable member. A piston pushes a predetermined number of such sheets upwardly through its respective basket into a receiving head which carries those sheets to the aligning and joining station. The finished packets are then carried by the aligning joining means to a discharging station.
