Abstract: Jumper cables (30), (54) and (62) with handles (10), (32) and (56) that do not become entangled when the cables (30), (54) and (62) are being moved to or from their stored positions. The new handles (10), (32) and (56) contain the normally open handle leg ends (17) and (19), (34) and (36), (70) and (72) in a closed position, thereby avoiding any entanglements. Embodiments of the new handles (10), (32) and (56) include: 1. a handle (10) in which normally open ends (17) and (19), (FIG. 1A) are contained in a closed position (FIG. 1C) by means of a notch (20), a latch (22), and a latch hook (21); 2. a handle (32) in which normally open ends (34) and (36), (FIG. 2A) are contained in a closed position (FIG. 2B) by means of semi-circular ring (38); and 3. a handle (56) in which normally open ends (70) and (72), (FIG. 3A) are contained in a closed position (FIG. 3B) by means of a cuff (64).

Abstract: Improved automotive jumper cables (10) having electrical connections to both legs (24) and (26) of handles (14). Each handle (14) has a flexible insulating cover (20). The covers (20) provide added protection against electrical burns, shocks and other accidents. The covers also prevent the handles (14) from becoming entangled with other items when the cables (10) are being moved.

Abstract: This is a machine for forming V-ditches for the irrigation of soil. The machine consists of a central frame with a two wheel carriage and plows of subassemblies. Each plow consists of a right subassembly and a left subassembly universally connected to the right and left sides respectively of the central frame. Each plow forms an acute horizontal angle with the central frame. The acute angle is fixed by the use of chains, having one part adjacent to an end attached to the central frame and another part of the chain adjacent to the opposite end, attached to the extended end of the subassembly. Each subassembly contains concavo-convex rotatable discs mounted parallel to each other on a common axle. The discs are assembled so that the concave side of the discs penetrate the soil when the machine is moved forward by a suitable draft device.
