Abstract: An adjustable support for an electric motor to enable the alignment of the latter. The support is made of two pairs of superposed beams transversely disposed relative to each other. The motor rests on the top beams and is displaced in the direction of these beams with threaded rods mounted through the ends of the latter. The top beams are slidingly mounted on the lower pair of beams by means of bolts in one pair passing through slots in the other pair. Each end of the top beams carries a screw which abuts against the lower beams. The turning of these screws causes the spacing or the tilt to vary between the two pairs of beams.
