Bail alignment marking device

Abstract

The present invention is used to mark the location on a piece of jewelry being constructed where the bail or embellishments are to be placed. It uses a stationary vee-shaped stop and a vee-shaped planar sliding marking guide to clamp the jewelry piece by pressing against the bezel that forces the jewelry piece into a position to be marked or scribed on front and/or back of the piece. This allows slots where the marking tool is placed to be perfectly aligned with the centerline of the bezel. The sliding marking guide relies on the clamping force exerted typically by rubber bands or springs, to force the jewelry piece into position using a guillotine effect. To assure the mark on the work piece is clean and precise, the clamping force is applied to the moving marking guide which lays flat against the back of the piece being marked. The mark is typically applied with a marking pen or a scribe.

Description

BACKGROUND OF THE INVENTION

The present invention is in the technical field of soldering, welding, and gluing, and more particularly in the technical field of material marking devices. And more particularly the present invention is in the technical field of jewelry tools.

Typically, in the previous art, when trying to mount a workpiece such as an oval gem into an oval bezel, most people rely on processes and tools that require the user to guess where the centerline of the oval bezel is located on the front of the workpiece, then mark that point on the front of the workpiece, then flip it over and guess where to mark the back so it is opposite of the front mark, in order to precisely place the bail. The purpose of this invention is to eliminate the guesswork.

SUMMARY OF THE INVENTION

In accordance with preferred embodiments of the invention, a tool is provided for aligning a work piece that has a raised area, e.g. such as a bezel, that is symmetric about a centerline. The purpose of the tool is to align the work piece so that it can be marked along a line parallel with that centerline. The tool has a first end housing and a second end housing that are attached to a fixed plate. The fixed plate has a rectangular shape having a first end attached to the first end housing, with the fixed plate having a symmetric vee-shaped cutout opposite the first end creating a first set of edges in the vee-shaped cutout. The vee-shaped cutout has an apex pointing toward the first end housing and defining a first direction, and the fixed plate has a plurality of elongated slots parallel with the first direction through which a marking device can mark the workpiece. At least one of the plurality of elongated slots is located directly in line with the apex of the vee-shaped cutout. The fixed plate further comprises two side rails, each side rail attached to the first end housing and to the second end housing, wherein the two side rails are parallel with the first direction and extend past the vee-shaped cutout in a direction opposite the first direction with the vee-shaped cutout therebetween. Each of the side rails has a channel therein for accommodating a sliding plane. The sliding plane extends between the side rails and has a symmetric vee-shaped cutout on one end creating a set of edges in the vee-shaped cutout of the sliding plane, the set of edges of the sliding plane hereinafter called a second set of edges. The vee-shaped cutout on the sliding plane is oriented in a direction opposite the vee-shaped cutout on the fixed plate. The sliding plane has a plurality of elongated slots in alignment with the plurality of elongated slots in the fixed plate. The sliding plane is moveably captured in the channels in the side rails, and the channels are configured to enable the sliding plane to slide under the fixed plate between the side rails in a direction parallel to the first direction, wherein the sliding plane can be moved relative to the fixed plate to create an open area between the vee-shaped cutout on the sliding plane and the vee-shaped cutout on the fixed plate. The open area between the cutouts is where the raised area of the work piece can be held in place between the first set of edges and the second set of edges. Also in the preferred mode a restraining element, such as one or more stretchable bands or springs, is provided to create a force in the first direction on the sliding marking guide to hold the raised area of the workpiece in place between the edges of the fixed plate and the sliding marking guide.

In the preferred mode, the tool further includes a floating marking guide located above the fixed plate, the floating marking guide having a flat side facing the fixed plate and a second side opposite the flat side. The floating marking guide has a first end and a second end, with the first end of the floating marking guide moveably captured inside the first end housing, thereby permitting motion of the first end of the floating marking guide perpendicular to the fixed plate. Similarly, the second end of the floating marking guide is moveably captured inside the second end housing, thereby permitting motion of the second end of the floating marking guide perpendicular to the fixed plate. The floating marking guide also has a plurality of elongated slots aligned with the plurality of slots on the fixed plate and the plurality of slots on the sliding marking guide.

To keep a downward pressure on the floating marking guide, the tool further includes a spring on each end, one spring captured between the floating marking guide and the first end housing, and the other spring captured between the floating marking guide and the second end housing. The springs are captured in a way to only permit vertical motion of the floating marking guide, so as to keep the elongated grooves on the fixed plate and the sliding plane in alignment with the elongated grooves on the floating marking guide.

DETAILED DESCRIPTION OF THE INVENTION

As shown in FIG. 1 of the preferred embodiment of the invention, parts 1 thru 7 are all components of the invention, whereas a work piece 8 and a marking device 9 are not. An end part 1 and an end part 1A are two vertical identical parts that provide support, alignment and spring enclosure for a spring 4 and spring 4A that are attached to a floating marking guide 6, which sits above a main body 2. Floating marking guide 6 is typically rectangular in shape with a plurality of elongated slots running substantially the full length of the rectangle. When assembled, each of end parts 1 and 1A is connected to main body 2. Main body 2 is substantially planar and has a top side shown in FIG. 1 and a bottom side shown in FIG. 2. The main body 2 is typically rectangular in shape and has two parallel side rails 21 and 22 with a symmetric vee-shaped cutout 23 on one end, between side rails 21 and 22, with the point of the vee preferably at the midpoint between the rails. Sliding marking guide 3 is planar with a rectangular shape with a vee-shaped cutout 33 on one end that has the opposite orientation of the vee-shaped cutout 23 of the main body 2. Sliding marking guide 3 is used to align the work piece 8 in the main body 2 in preparation for marking. Two stretchable bands 5 and 5A (or alternatively extension springs 7 and 7A) connected to sliding guide 3 via attachment elements 31 and 32 as shown in FIG. 3 are used to provide a clamping force on the work piece 8 to push it into position in the main body 2. The main body 2 has two channels, channel A on the same side as side rail 21 and channel A1 on the same side as side rail 22, to capture the sliding marking guide 3 between the rails (Shown in more detail in FIG. 4). The marking tool 9 is typically a pen or scribe used to make a mark on the work piece 8, and the work piece 8 typically has a raised area, such as a bezel, that is symmetric about a centerline. All parts of the embodiment other than the springs and stretchable bands are typically made of plastic, e.g. such as might be used in a 3D printer, although other materials could be used as well.

Shown in more detail in FIG. 2 is the bottom of the invention with both end pieces 1 and 1A connected to the main body 2. The sliding marking guide 3 is in position to clamp work piece 8 into main body 2 which forces correct alignment for marking with marking tool 9. Marking tool 9 is shown marking the front side of the work piece 8 thru elongated slots E located in main body 2. The elongated slots E in main body 2 are in alignment with the elongated slots F in floating marking guide 6.

Illustrated in further detail in FIG. 3 is the isometric view of the top of the embodiment showing the marking tool 9 in position marking the back side of the work piece 8. As illustrated, the work piece 8 is typically placed between the floating marking guide 6 and the main body 2. The marking tool tip is shown protruding thru the center slot in floating marking guide 6. Sliding plane marking guide 3 is being forced against work piece 8 wedging it against main body 2 by force created by stretched bands 5 and 5A that are attached to the sliding plane marking guide 3. Stretchable bands 5 and 5A are looped thru holes 11 and 12, respectively, located on opposite ends of end piece 1 and around the attaching points 31 and 32 on sliding plane marking guide 3.

FIG. 4 shows a more detailed bottom view of a cross-section of main body 2 illustrating where the sliding plane marking guide 3 is positioned in channels A and A1 that are located longitudinally in the inner edges of main body 2. The sliding plane marking guide 3 is positioned with vertical leading edges B and B1 wedging work piece 8 against vertical edges C and C1 of main body 2. A plurality of elongated slots D in sliding plane marking guide 3 and a plurality of elongated slots E in the main body 2 are used for marking on the front of the work piece. See also FIG. 2 for elongated slots D and E.

Shown in further detail in FIG. 5 is a partial top view illustrating marking tool 9 positioned with marking end protruding thru the floating marking guide 6 center slot FC making a mark on the back of work piece 8. It also shows the location of spring 4 on floating marking guide 6, and a spring housing 4S for holding spring 4 in place on floating marking guide 6. The opposite end of floating marking guide 6 is similarly constructed. End piece 1 is engaged with floating marking guide 6 which keeps floating marking guide 6 aligned correctly.

FIG. 6 shows a partial front view illustrating marking tool 9 positioned with marking end protruding thru the floating marking guide 6 center slot making a mark on the back of work piece 8. It also shows the location of spring 4 on floating marking guide 6.

Shown in more detail in FIG. 7 is a bottom isometric cutaway view of the preferred embodiment of the invention holding work piece 8, where end piece 1 and end piece 1A are positioning floating marking guide 6 in main body 2. The springs 4 and 4A are shown inside spring housings 1S and 1AS, which are hollow alignment columns, attached to end piece 1 and piece 1A where end piece 1 and end piece 1A are slid onto ends of floating marking guide 6. Housing 1S and 1AS are configured to slide down into housing 4S and 4AS, respectively, thereby holding springs 4 and 4A in place. Also shown is sliding marking guide 3 holding work piece 8 positioned against main body 2.

Those skilled in the art will understand that the purpose of the springs and alignment columns is to keep a downward pressure on the floating marking guide and to constrain the floating marking guide to move in the vertical direction and avoid any motion toward the side rails, so as to keep the elongated slots on the floating marking guide in alignment with those below. Further, although the hollow alignment columns are shown as cylinders, they could just as well have some other shape, e.g. they could be square or rectangular, open on the sides or closed on the sides, or even some other shape as long as they constrain the motion of the floating marking guide as described above.

FIG. 8 is a top isometric cutaway view showing the invention holding work piece 8, where the stretchable band 5 is attached to end 1 and around attachment element 32 of the sliding marking guide 3, causing work piece 8 to be aligned parallel to the center slots of floating marking guide 6. The ends 1 and 1A are positioning floating marking guide 6 in main body 2. The springs 4 and 4A are shown inside the housing 1S and 1AS as in FIG. 7. Also shown is sliding marking guide 3 holding work piece 8 positioned against main body 2.

The advantages of the present invention include, without limitation, enabling the person who is joining components by soldering, gluing, or welding and needs them to be aligned with precision, where a mark on the front and/or back is aligned with the centerline of another component, like a bezel or protrusion. It enables the user to make alignment marks without using the customary and cumbersome measuring tools typically used to serve this function.

In broad embodiment, the present invention is a tool for making alignment marks on the front and/or back of a piece being joined, where parallel alignment is necessary.

While the foregoing written description of the invention enables one of ordinary skill to make and use what is considered presently to be the best mode thereof, those of ordinary skill will understand and appreciate the existence of variations, combinations, and equivalents of the specific embodiment, method, and examples herein. The invention should therefore not be limited by the above-described embodiment, method, and examples, but by all embodiments and methods within the scope and spirit of the invention.
