| A device which can bend wire in any one of numerous regular patterns so that the wire can be dipped into a plastic solution to form simulated flowers, comprising a frame which can hold a spool of wire that is fed through guides that bend it in a selected pattern. The device includes a pair of wheels with contacting peripheries for feeding the wire into a pair of guides, one being a stationary guide and the other a movable guide that pivots in a regular pattern to determined the shape in which the wire will be formed. The movable guide is mounted at one end of a pivotally mounted arm whose other end is moved by a programmable cam arrangement. The programmable cam arrangement includes several holes formed in one of the wheels, pins which can be inserted into any of the holes, and a spring that urges the arm against the pins so that as the wheel rotates the pins pivot the lever to turn the movable guide.

| 177 | JEWELRY MANDREL PLIERS AND METHOD OF USING SAME | PCT/US2012041719 | 2012-06-08 | WO2012170927A3 | 2013-04-25 | BULLARD PATRICIA |
| 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. The mandrel pliers of the present invention may be used to grip wire or sheet metal and form it into unique shapes such as squares, triangles, ovals, or circles. 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, each having a different size cross sectional area than the other so that a shape of a larger size can be created on one side of the pair pliers and a shape of a smaller size can be reproduced on the other side of the pair of pliers. | ||||||
| 178 | TOOL FOR BENDING CEILING SUPPORT RODS | PCT/CA0200389 | 2002-03-21 | WO02074464A8 | 2002-11-07 | LAWRENCE DAYLE |
| A tool (10) for bending ceiling support rods (402). The tool (10) includes a first lever (20) and a second lever (40). The first lever has a first handle portion (22) and an associated first jaw portion (24), the first jaw portion (24) has a contoured surface (24a). The second lever (40) has a second handle portion (42) and an associated second jaw portion (44), the second jaw portion (44) has an edge (44a). Means (60) are provided for pivotally mounting the first lever (20) with the second lever (40), wherein the first jaw portion (24) and the second jaw portion (44) are opposite each other and are movable relative to each other when the first and second handle portions (22, 42) are compressed. The edge (44a) of the second jaw portion (44) is movable toward the contoured surface (24a) of the first jaw portion (24) when the first and second handle portions (22, 42) are compressed toward each other. | ||||||
