Abstract: A suspension mechanism for a four-wheeled automotive vehicle body with independently suspended wheels, comprises front and rear pairs of transversely aligned horizontal torsion bars rotatably supported by front and rear parts of the body. The transversely outer ends of these torsion bars are indirectly coupled to the respective wheels, so that these torsion bars undergo torsional displacement when their associated wheels are moved up and down. The transversely inner ends of the front and rear torsion bars are rigidly coupled to front and rear vertical arms the free ends of which are mutually connected by links extending in the front-to-rear direction of the body. One of the front and rear pairs of vertical arms are pivotally connected by a transverse lever pivotally supported at its middle parts by the vehicle body, whereby the diagonally opposite wheels move in the same vertical direction while the transversely opposite wheels move in the opposite vertical directions.

Abstract: A device is disclosed for positioning the slide of a press to compensate for insufficiencies of the stroke. A predetermined preload is first adjusted to the slide to take up clearances which may be present between the various moving parts of the press, dies and material to be processed. A slide preload compensating amount is then additionally adjusted to the slide equivalent to the amount of deformation of compression which the slide and frame will undergo during a working stroke. Therefore, the vertical position of the slide is established with the insufficiencies of the stroke eliminated.
