SEAT-SHAPING IMPLEMENT.
SPECIFICATION forming'part of Letters Patent No. 758,504, dated April as, 1904.,
Application filed June 3, 1903. Serial No. 159,954. (No model.)
To aZZ whom it may concern.-
Be it known that I, J AMES P. BOLDING, acitizen of the United States, residing at Terrell, in the county of Kaufman and State of Texas, have invented a new and useful Seat-Shaping Implement, of which the following is a specification.
This invention relates to means for forming and shaping seats in the prongs or clutches of studs and like devices employed in the setting of precious stones. As is well known to those skilled in the art, these seats are in the form of notches that conform to the edge of the Stone engaged therein. For instance, diamonds require triangular notches, flat bottomed seats are employed with flat stones, while round stones or pearls require curved seats.
One of the objects of this invention is to provide a simple implement which will form any of said seats with smoothly-finished faces. In expensive studs or mountings the clutches are made heavy enough to form the seats without altering the outer sides of the clutches, while with cheap settings the prongs must be bent bodily to form said seats.
Another feature of the invention resides in fan implement so constructed that it will operate upon these difierent classes of jewelry.
The preferred form of construction is illustrated in the accompanying drawings, where- Figure 1 is a side elevation of the improved implement. Fig. .2 is a similar view, the jaws and dies being shown in section. Figs. 3 and 1 are detail perspective views of the dies. Fig. 5 is aview of two prongs of the cheaper variety of setting and illustrating the forms of the seats. Fig. 6is a sectional view of the implement whenconstructed to operate upon the more expensive studs. Fig. 7 is a detail sectional view showing one of said studs in place in the implement. Fig; 8 is a view illustrating the different forms of seats made in the expensive clutches and also illustrating one of said clutches before being operated upon. Fig. 9 is a detail perspective view of the positioning device.
Similar reference-numerals indicate corresponding parts in all the figures of the drawlngs.
The implement comprises a pairof levers 10, crossed between their ends and secured together bya pivot 11, the arms of these levers on one side of the pivot constituting handles 12, while the arms on the other side form jaws 13, that have flat coasting faces. Upon the inner face of one of these jaws is rotatably mounted a carrier 1 which is journaled upon a bolt 15, passing through the jaw and projecting beyond its inner face, the outer end of said bolt being threaded to receive a clamping-nut 16, that is screwed thereon. The carrier is provided with a plurality of outstanding projections carrying on their inner faces male dies 17. The active faces of these dies are of the shape of the seats to be formedfor instance, one is triangular, while another is rounded, as illustrated clearly in Figs. 1, 2, and L. The opposite jaw is preferably extended beyond the jaw carrying the male dies, so that the outer die, or, in other'words, the one farthest from the pivot, will be located in line with the free end thereof. J ournaled upon the inner face of this other jaw is a. rotatable carrier 18, provided with'recesses 19, constructed to receive the male dies, and thus forming female dies. The carrier 18 is journaled upon a bolt 20, that passes through the jaw and has its outer end threaded to receive a clamping-nut 21.
' A positioning device in the form of a metallic strip 22 is located longitudinally upon the outer face of the jaw which is provided with the female die member, this carrier having one end projecting beyond the end of the jaw and inturned so as to be in line with the space between the jaws. Said end is bifurcated to provide guide-prongs 23, while the opposite end has an upturned lip 24. The po- 'sitioning device, furthermore, has a longitudinally-disposed slot 25, through which the journal-bolt 20 passes, the clamping-nut 21 thus bearing against said positioning device. A stop-screw 26 is threaded through one of the jaws and is adapted to engage the other jaw to limit their movement toward each other. If desired, this screw may be placedupon the handle portion, as indicated in dotted lines in Fig. 1.
In the cheaper class of jewelry-settings the prongs or clutches are comparatively light,
so that the notches must be formed by bending said clutches bodily, as illustrated in Fig. 5. In forming these seats the arrangement illustrated in Figs. 1 and 2 is employed. The clutch is positioned between the prongs 23, and the free end thereof is placed between the proper dies, the carriers having been first rotated to bring said dies to the outer ends of the jaws and afterward clamped by the nuts 16 and 21. The jaws are then brought together by pressure upon the handles 12, and consequently the notch or seat is formed. This operation is performed on the different clutches constituting the setting. If, however, the more expensive mountings are employed, as illustrated in Fig. 8, the clutches are considerably heavier, so that the notches can be made without changing the outer sides of the same. The carrier 18 is detached, and the inner face of'the jaw coacts directly with the male die. The prongs or notches are successively placed in the positioning device and against the flat face of the jaw, the die being forced into the metal so as to press the seat from the same. It will thus be seen that the male dies are arranged to coact either with the female dies or with the flat face of the adjacent jaw, so that the implement Will operate upon either class of jewelry. In the first or cheaper class the clutches are not weakened, as they are bent bodily. In the second or more expensive class, though Weakened to a certain extent, no metal is removed, as has been the custom, and the method therefore is advantageous, as the metal is simply compacted about the seats. The positioning device is adjustable 'to prongs of different lengths, and it will also be observed that a common fastening device is employed for the carrier of the female dies and the positioning element. such arrangement thus reducing the number of parts.
From the foregoing it is thought that the construction, operation, and many advantages of the herein-described invention will be apparent to those skilled in the art Without further description, and it will be understood that various changes in the size, shape, proportion, and minor details of construction may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-
1. In a seat-shaping implement, the combination with supports movable toward and from each other and having coactiug faces, of a die carried by one of the faces, said die projecting beyond the same and toward the other face,
and a stop for limiting the movement of the supports toward each other and preventing the engagement of the die with the opposing face.
2. In a seat-shaping implement, the combination with supports movable toward and from each other, of a plurality of coacting male and female dies carried respectively by the supports and projecting beyond different sides of the same, said dies being arranged to form a notch in one face of an article placed therebetween.
- 3. In a seat-shaping implement, the combination with supports movable toward and from each other, of a plurality of coacting male and female dies carried respectively by the supports and projecting beyond different sides of the same, said dies being arranged to form a notch in one face of an article placed therebetween, and means for limiting the movement of the supports toward each other.
