Abstract: The present invention provides a mandrel tool and method for more efficiently and consistently forming various shapes of material. In one embodiment of the invention, a pair of pliers having mandrel jaws that are shaped with a uniform cross sectional area throughout a length of the mandrel jaw is used to replace the traditional tapered mandrel. Because the mandrel jaws have a uniform cross sectional area, the wire, for example, can be wrapped multiple times around the mandrel jaw when it is desired to produce multiples of the same shape. For added versatility, the pliers can have opposing mandrel jaws, with different size cross sectional area.

Slots or channels are provided on the first neck portion for selectively guiding a stop pin mounted on the second neck portion and for selectively guiding the other end of the link generally linearly along a first predetermined length of the first handle. A third guide slot selectively guides the other end of the second elongate member generally linearly along a second predetermined length of said second handle.

Abstract: A pliers is composed of a first long member and a second long member having a middle neck portion which is provided with a long slot. Pivoted to the first long member is a stopping member, which is located in the long slot and provided with a serrated portion engageable with teeth of the long slot. A first spring is fitted over a second support arm which forms an angle with a first support arm. A second spring is fastened at one end thereof with a grip end of the first long member, and at another end thereof with a grip end of the second long member. The first and the second long members are forced by the springs to open up completely in the absence of an external force exerting on the pliers.

Abstract: A hand-mounted accessory for opening a twist-off cap bottle, the accessory being comprised of an elongated flexible web and flexible loops off the web near its opposite ends. The flexible loops are sized to fit over and be secured onto the user's thumb and index finger in the region between the first and second knuckles, the web ending near the second knuckles and between the loops then lying closely proximate and substantially aligned with the hand web portion between the thumb and index finger. The web is further sized to wrap more than half-way around and overlie the side edges of the twist-off cap even if the web is not exactly aligned parallel to the side edges. As hand-mounted, the accessory web automatically will be positioned against the cap side edges as the user's thumb and index finger close over the cap side edges during hand manipulation needed to twist the cap off the bottle.

The resilient wire has a first end extending inwardly and upwardly toward the gripping area. The resilient wire has a second end extending inwardly and upwardly toward the gripping area. The second end is at an opposite end of the resilient wire from the first end. The first end is angled outwardly from a side of a plane of the resilient wire. The second end is angled outwardly from an opposite side of the plane of the resilient wire. Each of the first and second ends has a rounded end point. The first and second ends extend upwardly from a bottom of the resilient wire at an angle of less than 90 degrees.

Abstract: A gripping device comprises a thin strip of flexible material which is disposed between a user's index finger and thumb to facilitate gripping, particularly bottle cap removal. The flexible strip includes attachment bands which secure the strip to the thumb and index finger for use.

Abstract: An insulated fastener retainer includes an oval sleeve and oval ring coupled by a plurality of connectors and supporting a pair of oppositely positioned elongated beams. The beams are secured to the flat sides of the oval ring at one end and are received within insulating blocks at the outer ends. A pair of resilient jaws having grip portions are coupled to the insulating blocks and are movable in response to movement of the elongated beams. The fastener retainer is received upon a screwdriver shaft and is maintained thereon by the oval sleeve. The elongated beams and jaws are separated by the user's application of a squeezing force to the ends of the oval ring thereby distorting the oval ring and separating the fastener retainer jaws.

Abstract: Prior universal pliers with two gripping arms (11, 15) and an adjustable jaw have the disadvantage that during adjustment one must change hands while using the pliers which is unfavourable as regards the economic requirements. This disadvantage is obviated by the present invention in that both gripping arms (11, 15) are non-displaceably articulated on one another and one of the two jaws (19) is displaceably mounted with respect to its associated gripping arm (15) at right angles to the jaw opening.

Abstract: A tool for removing headed stoppers from bottles such as champagne bottles, includes a base having a two fingered yoke and a side support, sized and shaped to engage the upper lip and the side of the neck of the bottle respectively, so that when a handle, pivotally attached to the base, is lowered toward the bottle, a pair of inwardly biased jaws slide down over the head of the stopper to engage its undersurface between the fingers of the yoke. Thereafter, the handle is lifted extracting the stopper while inwardly facing extensions positioned above the stopper on the jaws restrict upward motion of the stopper to prevent uncontrolled motion thereof.
