Abstract: A vehicle jack of the type known as "Y-jacks". It has a base plate (1) with perforated fins that receive and fix, in a particular way, the protruding necks on the wings of the jack body. A nut (13) is secured to the end of the body, with easy entrance into the end and fixed by some lugs (14) which are bent over the central portion of the nut. The arm (3) of jack also has two protruding necks towards the interior, on which a cross member is received, formed by a part with a U-shaped section whose wings or sides clasp on to the necks, are made with U-shaped openings. The base of the cross member is controlled by a special easy entrance holder plate on the housing on the arm. An arm (30) of a specially designed shape acts in combination with a holder plate-cross member, whose seating for the vehicle has a metal insert. This holder plate-cross member is provided with an external retainer on which the end of the screw spindle is supported.

Abstract: This is an articulated jack with two pairs of arms, connecting at one end with a nut (11) and at the other with a bar (12). Both these are in turn connected by a spindle worked by a crank winding handle. The other ends of the arms rotate around a base (1) and a gripping device (2.about.. The outer arms (3, 4) and inner arms (5, 6) are in turn connected by auxiliary parts (18). The actual size of the jack has been considerably reduced.

Abstract: An automatic tensioning device for hand brake levers, with an enclosed casing (9) and rectangularly hollow in its interior, which is situated on the lever or on its support base. The interior of the casing is hollow, with one of its ends being tapered at the sides (24), and receives a square-shaped slide (1) with toothed sides (2) inside this hollow. This slide combines with two other attached parts (13, 14) that are toothed on the corresponding sides and that have wedge-shaped ends (23). These attached parts (13, 14) are forced by a spring against the narrowing taper of the casing, and the front end (4) of the slide is secured to the brake cables.

Abstract: A lightweight vehicle jack of the "Y" type includes aluminum, particularly in the arm (2) and the central body of the device (1). A gripping device (7) provides a larger surface area to take the edge of the body of the vehicle. On the side to which the nut (4) is fitted, the body of the device (2) has lateral reinforcing vertical ribs at 90 degrees, and there is an L-shaped internal reinforcement device (20) between the gripper (7) pivot and the pivot of the shaft of the bar (5), to reduce the thickness of the arm (1). The support base controls the body's passage to the interior of the jack.
