DESCRIPTION OF SPECIFIC EMBODIMENTS OF THE INVENTION

The present invention, in some embodiments thereof, relates to a flaring tool for an invisible setting and, more particularly, but not exclusively, to a flaring tool that flares a coronet or mounting, being an intermediate member between the stone and the setting.

For purposes of better understanding some embodiments of the present invention, as illustrated in Figures 3 - 28 of the drawings, reference is first made to the construction and operation of a mounting or coronet as illustrated in Figures 1 and 2. Figure 1 shows a mounting 10 which holds a grooved gemstone 12 invisibly to a setting such as a ring or other item of jewelry. The mounting 10 has a first end 14 designed to hold the gemstone 12 at groove 16 using protrusions 18 of two oppositely facing arms 20 and 22. The protrusions 18 extend inwardly from the arms 20 and 22 to fit the groove. The mounting 10 further has a skirt 24 which extends through a receiving hole in the setting, not shown. As shown in Fig. 2, the deformation may be carried out by a beveling tool 44 or the like. Beveling of the base 28 of the holder 24, as discussed, causes the arms 20 and 22 to close over the gemstone and hold the gemstone more strongly via the groove.

The mounting, and more specifically, the holder 24, is designed to be deformed when pulled into the setting. In particular the deformation causes the top part of the arms to press into the girdle, jamming the stone in position. The holder 24 is hollow. Furthermore the cylindrical outer walls 27 of the holder may be relatively thin along their length in between base 28 and the meeting point 29 with the arms. The relatively thin walls which may in some cases be combined with an open slit, provide a relatively weakened portion of the mounting to provide for controlled deformation, allowing a specifically desired deformation to be preferentially caused by the mounting.

The flaring tool of Fig. 2 pushes the skirt of holder 34 outwards and upwards.

The present embodiments may provide a flaring tool for flaring a hollow skirt- type base of a mounting, the flaring tool comprising a grabbing mechanism for internally grabbing a location within the skirt and a pressing mechanism for pressing down on the base against the grabbed location to cause flaring of the base. There is also provide a mounting for holding stones within a setting that a hollow base and indentations within the hollow base for flaring by the flaring tool to secure the mounting within the setting.

Before explaining at least one embodiment of the invention in detail, it is to be understood that the invention is not necessarily limited in its application to the details of construction and the arrangement of the components and/or methods set forth in the following description and/or illustrated in the drawings and/or the Examples. The invention is capable of other embodiments or of being practiced or carried out in various ways.

Referring now to the drawings, Figure 3 illustrates flaring tool 50 and tip 52 according to the present embodiments and the holder or skirt 54 of the mounting. In Fig. 3 the skirt is shown prior to flaring to fix the stone in position and in Fig. 4 the identical parts are shown after flaring. The flaring tool is intended to flare the skirt as shown in Fig. 4. The skirt includes indentations or clutch holes 56 on two sides and is otherwise smooth. The tool has a rotary pin with clutch anchors which extend outwardly in two directions to form a T-shape. In one embodiment, the skirt 54 is flared by pressing the handle of the tool, so that the rotary pin, which will be discussed in greater detail below, starts to rotate 45 degrees so that the clutch anchors slide underneath the clutch hole indentions and grab the skirt from below. A press pin- hereinafter a shaft, also discussed below, pushes down to a flaring position to flare the skirt as the skirt is squeezed between the shaft and the clutch anchors. The handle is then released, allowing the rotate pin to turn back into the original position to extract the tool. Such an action does not cut the anchor clutch 56 which is cut into the skirt 54. Figures 5 and 6 likewise show the skirt 54 before and after flaring, but in this case the skirt is cut away at the clutch holes 56. More particularly, the skirt 54 is flared by pressing the handle of the tool, so that the rotary pin starts to rotate 45 degrees and the anchor clutch slides under the indentations of the clutch holes 56. The press pin or shaft pushes down to a flaring position to squeeze the cylinder against the clutch and flare the cylinder. The user continues to press the handle so that the same function continues and the press pin continues to push down to the maximum position while cutting the skirt at the clutch indentations. The handle is released and the tool comes out as the rotary pin returns to the original position, as will be explained in greater detail below.

Reference is now made to Figures 7 to 17 which illustrate successive positions of an exemplary flaring tool according to the present embodiments carrying out flaring of a skirt according to Figures 3 and 4 above, where the skirt is not cut.

Fig. 7 illustrates the start of the flaring process. The flaring tool 100 is shown as a cross-sectional whole in the center of the image, with a cross-sectional detail of the head end shown above and a detail of the tool head below right.

The tool head 100 comprises a rotary pin 101 which fits inside skirt 54 of the mounting to carry out flaring. The skirt has anchor clutch grooves 56 cut therein at two sides and is smooth at the remaining two sides. Shaft 102 is an outer shaft which presses directly against skirt 54 as explained below. An underlying shaft 103 extends under shaft 102 and is rotated by screw 113 to operate rotary pin 101. L-shaped arm 104, 106 consists of an upper part 106 with a cam follower 130, and a lower part 104. The arm 104,106 is pivoted at pivot point 108 and the lower part 104 extends into track 114. When pushed by cam 107, the L-shaped arm pivots so that the lower part 104 of the arm pushes downward into the track 114, which in turn pushes downward on shaft 102 as handle 109 is squeezed. Arm 105 is hinged on pivot 122 and has cam follower 124. The arm pivots around second pivot 122 and extends into an angled groove 119 in screw 113 to impart rotation as the handle 109 is depressed. 106 Cam 107 follows track 120 and presses against cam follower 124 to change the angle of arm 105 as the cam advances. 108 Handle 109 is depressed against spring 112 to rotate the pin 101 by advancing cam 107. Cylinder 110 is attached to handle 109 and extends into a shaft which pushes forward against the restoring force of spring 112 when the handle 109 is depressed. Screw 113 contains an angled groove 119 and is forced to rotate as arm 105 advances.

At the start of the flaring process the rotary pin 101 is aligned with skirt 54 of the mounting which is to be flared. The T-parts or clutch anchors are aligned away from the clutch indentions 56 of the skirt.

The skirt 54 is flared by pressing the handle of the tool, so that the rotary pin 101, is inserted into the skirt with the clutch anchors misaligned and able to slip below the indentations. Then further pressing of the handle causes a rotation, say of 45 degrees in the rotary pin so that the clutch anchors slide underneath the indentations. A press pin, made up of shaft 102, pushes down to a flaring position to squeeze the skirt 56 between the clutch and the shaft, thereby to flare the skirt 54. The handle is then released, allowing the rotary pin 101 to return to its original position to extract the tool. Such an action does not cut the anchor clutch 56 which is cut into the skirt 54.

Fig. 8 illustrates insertion of the rotary pin 101 inside the cylinder or skirt 54 of the mounting.

Figs. 9 - 13 illustrate successive stages in the way in which the rotary pin 101 is rotated by pressing handle 109. Handle 109, on being depressed, pushes cylinder 110 which in turn pushes cam 107 along track 120. Arm 105 is pushed downwards by the cam 120 as the cam moves along cam follower 124, and arm 105 pivots upwards as it extends into angled groove 119 in screw 113, causing screw 113 to rotate. The screw 113 rotates, turning an underlying shaft 103. The shaft 103 connects via the screw 113 with rotating pin 101, and thus pin 101 is rotated by depressing of the handle 109. Anchor clutch 126, which is a T termination of the rotary pin 101, rotates to engage the clutch holes 56.

Meanwhile the same motion of the handle also pushes the same cam against L- shaped arm upper part 106, which is loosely attached to pivot 122 and securely pivoted on second pivot 128. Cam 107 pushes against cam follower 130 of arm 104 and advances the tip of arm 104 into track 114 which depresses shaft 102. The shaft 102 presses down on the skirt 54 at the same time as the clutch holes are engaged by anchor clutch 126, thus causing the skirt 54 to be squeezed between the anchor clutch and the end of the shaft, causing flaring with the leveraged power of the pressure on handle 109. That is to say the clutch pulls as the shaft pushes to provide a push-pull flaring action. Figure 12 shows the initial engagement of the shaft with the skirt and Fig. 13 shows the shaft having advanced far enough into the skirt to cause flaring.

The handle is now released and spring 112 restores cam 107 to its initial position at the handle end of track 120, with the effects shown in Figs 14 - 17. In Fig. 14, the shaft has returned to its initial position. The anchor clutch 126 rotates out of the clutch holes 56 in Figs 14, 15 and 16, and the pin is withdrawn from the now-flared skirt 54 in Fig. 17.

It is noted that instead of rotating, the anchor clutches may be spring loaded to be pressed inwardly over the clutch holes or indentations as the tool is inserted into the base and then to slide outwardly to anchor underneath the indentations by springing back out.

Reference is now made to Figures 18 to 28 which illustrate successive positions of an exemplary flaring tool according to the present embodiments carrying out flaring of a skirt according to Figures 5 and 6 above, where the clutch holes are cut. The cutting of the clutch holes may add additional squeezing to the flaring operation and allows the flaring tool to come out more easily, as it can be withdrawn just as easily from the aligned or misaligned orientations.

In the embodiment where the clutch hole indentations are cut, the internal construction of the tool is the same, however the operation is slightly different. Figures 18 to 28 show the shaft and rotating pin at various stages of being inserted into the skirt, carrying out flaring and being withdrawn.

In Figs. 18 - 28, the inset shows a series of mountings 200, each with a stone 202, built into a single multiple setting 204. The mountings are flared one by one from below using tool 206, to fix the mountings into the setting.

The main part of Fig. 18 shows one of the mountings 200 in cross section with the tool aligned with the skirt 54 from above. The clutch anchors 126 are misaligned with the clutch indentations 56 in the in the skirt 54.

In Fig. 19, the rotary pin 101 is inserted into skirt 54 with the anchors still misaligned so that they extend smoothly under the indentations.

In Fig. 20, the rotary pin is rotated in accordance with arrow 210, so that the clutch anchors 226 slide underneath the indentations 56. A typical rotations may be 45 degrees. In Fig. 21, the shaft 102 continues downwards so that the skirt 54 is trapped between the clutch anchors 126 and the shaft 102 and is squeezed. The squeezing operation continues in Figs 22 and 23 which each illustrate different stages of squeezing and the skirt flares.

In Fig. 24 the shaft 102 completes the flare and the rotary pin 101 is pulled sharply up so that the clutch anchors 126 cut the metal at the top of the indentations 56 on either side against the base of shaft 102. Fig. 25 shows the clutch anchors 126 pulled almost right against the base of shaft 102 so as to crease and break any metal in their path.

In Fig. 26, the rotary pin 101 is pulled inside the shaft 102 and shavings 212 from the cut metal remain with the rotary pin 101 as it is withdrawn.

Fig. 27 shows the tool withdrawn, with the rotary pin 101 still withdrawn within shaft 102.

Fig. 28 shows the rotary pin extended from shaft 102 so that shavings 212 may be cleaned off ready for flaring the next coronet.
