Abstract
A portable hand beading tool having a pair of handles pivoted together for relative rotation about a pivot axis. The tool has a pair of spindles each mounted on a respective handle and rotatable about spindle axes parallel to the pivot axis. The spindles have adjacent circumferential surfaces separated by a variable width gap controlled by relative rotation of the handles about the pivot axis so that a workpiece may be clamped between the spindles. The circumferential surfaces of both spindles have mating profiles that are formed on a workpiece clamped between the spindles. A multi-position lock holds the handles in position during workpiece deformation. The tool is positioned parallel to the edge of the workpiece so that on passage of an edge of said workpiece between the counter-rotating spindles, the workpiece is deformed by the spindles to form a continuous bead profile.

The recess is designed to receive the part-spherical end of the projection.
- U.S. Pat. No. 4,825,676 teaches a metal forming tool with a driving means for forming a step or flange in sheet metal.
- U.S. Pat. No. 5,084,935 teaches a multipurpose, pliers-like tool for use in dentistry. Among the many features of the tool are two pairs of complementary male and female corrugating elements, a wire bending arrangement including an elongated groove and an elongated rib receivable in the groove, and a channel which can receive, in part, the free end of a cone.
- French Patent No. 669,598 illustrates a tool having a first jaw with a wide, arcuate channel and a second jaw with a narrow groove.
- Swiss Patent No. 44,706 discloses a tool with two sets of dies. Each die is formed with an arcuate groove.
- None of the above tools is designed to form a continuous circumferential bead in sheet metal stock at a fixed distance from the edge of the sheet metal stock.
- A portable hand beading tool having a pair of handles pivoted together for relative rotation about a pivot axis. The tool has a pair of spindles each mounted on a respective handle and rotatable about spindle axes parallel to the pivot axis. The spindles have adjacent circumferential surfaces separated by a variable width gap controlled by relative rotation of the handles about the pivot axis so that a workpiece may be clamped between the spindles. The circumferential surfaces of both spindles have mating profiles that are formed on a workpiece clamped between the spindles. A multi-position lock holds the handles in position during workpiece deformation. The tool is positioned parallel to the edge of the workpiece so that on passage of an edge of said workpiece between the counter-rotating spindles, the workpiece is deformed by the spindles to form a continuous bead profile.

FIG. 1 is a perspective of the hand beader viewed from the spindled side, handles open. -
FIG. 2 is a side view of the hand beader, handles open. -
FIG. 3 is a perspective of the hand beader viewed from the spindle side, handles closed, forming a bead. -
FIG. 4 is a perspective of the hand beader viewed from the spindle side, handles closed, forming a bead, single handed. -
FIG. 5 is a photograph of a working prototype. - The portable hand beading tool shown in
FIGS. 1 and 2 comprises a pair ofhandles bolt 3 passing through holes in the forgings and secured by a nut (not shown). The handles are dimensioned and shaped so that both their free ends are easily grasped in one hand and pressed together by an operator. Rigidly attached to the end ofhandle 2 adjacent the pivot is afemale spindle 4 which projects outwardly parallel to the axis of the pivot. Rigidly attached to the end ofhandle 1 is amale spindle 5 which similarly projects outwardly, parallel to and besidefemale spindle 4.Male spindle 5 mounts in a hole inhandle 1 with a nut securingmale spindle 5 to handle 1.Female spindle 4 mounts in a hole inhandle 2 with a nut securingfemale spindle 4 to handle 2. Both spindles and holes are arranged so that ashandles bolt 3 thedistance separating spindles Multi-position lock 6 pivots aroundpin 9 to lock the handles in a closed position. -
Female spindle 4 has a convex circumference surface andmale spindle 5 has a concave circumference surface arranged so that the surfaces mate and overlap when thehandles spindles handles workpiece 7, such as sheet metal, is located between the spindles with the tool handles parallel to theworkpiece 7 edge. When the handles are closed so that the spindle circumferential surfaces mate, as seen inFIGS. 3 and 4 , theworkpiece 7 is deformed to form abead profile 8 near the edge. The handles are then locked closed usingmulti-position lock 6 and the tool is pulled parallel to the fixedworkpiece 7 edge to form acontinuous bead profile 8 in theworkpiece 7. Thebead profile 8 is continuous and does not require multiple tool engagement taught in the prior art where incremental bead sections are formed to simulate a continuous bead. While pulling the tool, bothspindles workpiece 7 edge to form acontinuous bead profile 8 of constant width and depth. During this operation the handles are conveniently held with one hand to free the other hand for positioning theworkpiece 7. - In the device shown in the drawings the spindles are firmly attached to the handles so that they are not splayed out by the force exerted by the workpiece on the spindles during deformation. However the radius of the circumferential surfaces of the spindles is relatively small so that the tool is easily maneuvered along a metal edge, which may have curves of relatively small radius.
- In the tool shown in the drawings the spindle circumferences are rounded so that the profile of the bead formed is perpendicular to the plane of the workpiece. Alternatively the spindle circumferences may be of different shapes to provide different profiles, the opposed portions of the spindles still being complementary to each other. For example the spindles may be half-round, quarter-round, triangular, frusto-conical, or other profile to provide a bead which is oblique or non-symmetric to the plane of the workpiece.
- When the tool is used it is very desirable that the gap between the spindles should be constant as the spindles move along the workpiece edge, as otherwise the magnitude of the bead formed will vary; also when the workpiece is of soft metal such as aluminum the sheet may become thinned if the spindles are held too closely together. The
multi-position lock 6 on the tool has multiple settings to compensate for workpiece material variances whereby the spindles may be set at the desired separation when the workpiece is first clamped between them and this separation is then held constant as the tool moves along the workpiece edge. - The invention has been described in terms of specific embodiments which are indicative of a broad utility but are not limitations to the scope of the invention. Additions and modifications apparent to those with skill in the art are included within the scope and spirit of the invention.
