Abstract: An auxiliary table is provided for use in combination with a machine tool having a horizontal table and a spindle mounted for moving vertically relative to the table. The auxiliary table includes a circular table top rotatably mounted to the top of a support pedestal. A plurality of fixtures and/or jigs are mounted to the table top in an outer, annular area thereof and the auxiliary table is placed such that by rotation of the top the fixtures may be selectively positioned below the machine tool spindle for holding a part for being operated on by a tool carried by the spindle. Tools are stored beside the fixtures and/or jigs.

Abstract: A tilt mechanism is disclosed for adjusting the angle of rest of an infant contained within an infant incubator. The tilt mechanism comprises at least one bent rod that underlies the bed on which the infant is positioned. By rotating the bent rod, an offset shaped portion of the rod elevates one end of the infant bed. The rotation is effected by a handle located outside the incubator and which has a plurality of positions, each of which position is locked in place by a spring biased plunger that enters certain grooves formed in the interior surface of the handle. A push button pushes against the spring bias to move the plunger out of engagement with the grooves in the handle so that the handle can be rotated to another selected position.

Abstract: A machine tool bolster includes a horizontal fixture support plate and a pressure-operable clamp device is vertically shiftably mounted to the underside of the plate and includes a clamp insert holder extending axially into a circular hole provided in the plate. A fixture is mounted to a locating plate provided with a receptacle adapted to receive the clamp insert holder when the clamp device is raised relative to the plate. A rod is connected to a piston of the clamp device and extends vertically through the holder. The upper end of the rod is conically shaped and acts against complementary shaped clamp inserts radially slidably mounted in the holder to shift them outwardly against a conically flared portion of the locating plate receptacle so as to clamp the fixture to the bolster.
