GEM-SETTING DEVICE.
Specification of Letters Patent.
Patented April 2'?, 1909.
Application led March 20, 1908. SeralNo. 422,340.
To all whom it may concern:
Be it known that I, RAMEY KIRKwoOD, a citizen of the United States, residing at Scranton, in the county of Jackson and State of Mississippi, have invented a new and useful Gem-Setting Device, of which the following is a specification.
The invention relates to improvements in gem setting devices.
The object of the present invention is to improve the construction of gem setting devices, and to provide a simple, inexpensive and efficient gem setting device, adapted to clamp and securely hold gems of different forms and sizes in settings, while the prongs thereof are bent into engagement with the facets of the gen1.
A further object of the invention is to provide a gem setting device of this character, adapted to be readily arran ed to support a ring or stud, ear ring, or ot 1er setting, and to clamp gems having either flat or round surfaces.
`With these and other objects in view, the invention consists in the construction and novel combination of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claims hereto appended; it 1coing understood that various changes in the form, proportion, size and minor details of construction, within the scope of the claims, may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.
In the drawingszmFigure 1 is a perspective view of a gem setting device, constructed in accordance with this invention and arranged for clamping a gem in a stud or analogous setting. Fig. 2 1s a vertical longitudinal sectional view ot the same. Fig. 3 is a detail sectional view, illustrating the construction of the movable reversible gem engaging point. or member.. Fig. 4L is a detail sectional view, illustrating the modification of the 0ein engaging point or member. Fig. 5 is a thorizontal sectional view, illustrating the manner of mounting the mandrel or setting support. Fig. 6 is a side elevation of the gem setting device, illustrating another` form of the mandrel or setting support. Fig. 7 is a vertical sectional view on the line 7-7 of Fig. 6. Fig. 8 is a detail perspective view ot the mandrel or setting support, shown 1n Flg. 6.
Like numerals oi reference designate corresponding parts in all the figures oli the drawings.
1 designates a vertical post having a lower reduced end 2, and designed to be clamped between the jaws of a vise 4, but any other suitable means may be employed for mounting the gem setter in position for operation. The post is provided in its lower portion with a horizontal opening 5 for the reception of a reduced end or shank G of a mandrel or setting support 7, which is adjustably secured to the post by means ol a set screw S. The shank or end is squared, and the lower opening of the post is rectangular to permit the mandrel 7 to be reversed to present either its upper or lower face at the top.
The mandrel 7, which is hollow, has [lat upper and lower l'aces 9, each provided at intervals with concave seats l0, which are intersected by a longitudinal slot 11. The concave seats, which consist ol' beveled or counter-sunk openings, are adapted, as illustrated in Fig. 2 ol the drawings, to receive and support a stud setting 12, but the mandrel is adapted i'or holding car ring setting* scart' pin settings and the like, as will be readily understood. The seats vary in diameter, the up )er and lower series being provided for ena ling a comparativelylarge range of adjustment to be afforded by the gem setting device. The slot 11 permits the setting to be moved inwardly and outwardly from one side to another, and the bore or opening of the hollow mandrel receives the spiral or screw oi' a stud setting, or the shank portion o'l' an ear ring setting or the pin ol' a scarll pin setting.
The gem or stone 13 is clamped in the. setting by means oll a vertically adjustable clamping screw 14, having a hollow lower portion 15, forming a socket l'or the reception ol' a removable reversible gem engz'lging point or member 16. The screw 14 is mounted in a threaded opening 17 oll a luuizontal arm i8, adjustably secured in an upper opening l() ol' the post by means ol' a set screw 20. The arm 1S is preferably polygonal to hold it against rotary movement, and the post is provided at its upper end with a vertical threaded perforation 21, con'nnunicating with the vertical openingl and receiving the set screw 20, which engages the adjustable arm 1S.
The socket 15 is cylindrical, and the gem engaging point or member, which is oppo- IOS llO
sitely tapered, is adapted to have eitherterminal fitted in the socket of the screw., and it is equipped With flat and concave end faces 22 and 23 to enable it to engage either'tli'e flat or round face of a geni or stone. The upper' arm 1S is adjustable inwardly and outwardly to arrange the clamping means in proper position With relation to the vsetting and the gem, and when the screw is adjusted to engage the stone or gem, the latter is securely held in proper position, While the prongs of the setting are engaged with the facets of the gem.
ln Fig. 4 or" the drawings is illustrated a modification of the gem engaging member, the gem engaging member 24 being composed of a relatively large lower body portion and a reduced shank 25, which is removably fitted in the soclet of the clamping screw. The lower end of the member 24 is flat, but may be of any other configuration, as will be readily understood.
ln Figs. 6 and 8 of the drawings is illustrated a ring receiving mandrel 26, provided With a squared shank 27 to lit the lower opening 5 of the post and secured in the same by the lower set screw 8. The ring receiving mandrel is tapered to lit rings of diHerent sizes, and in practice, the device Will be equipped With a plurality of such mandrels to suit the various sizes oi linger rings. The
mandrel 26, Which is provided With a longitudinal groove 28, may be readily substituted for the mandrel 7, when desired. The groove is arranged to receive the projecting points of the gems to prevent the same from coming in contact with the ring mandrel, but the latter may be out away in any other desired manner to enable the gems of the ring to clear the mandrel.
Having thus fully described my invention, what l claim as new and desire to secure by Letters Patent, is
l. A gem setting device comprising a post having its lower end arranged to be clamped in a vise, a detachable mandrel extending from the post and constructed and arranged to receive settings ci different sizes, an arm located above the mandrel and adjustably mounted on the post, and a gem-engaging clamping screw mounted on the arm and carried by the same in the adjustment thereof t0 arrange the said clamping screw at diierent points along the mandrel.
2. A gem setting device comprising a post, a mandrel extending Yhorizontally from the post Yand constructed and arranged to receive settings of dirlferent sizes, a horizontal arm located above the mandrel and adjustably mounted on the post, and a gem engaging clamping screw mounted on the arm and carried by the same in the adjustment tliereof to arrange the said clamping screw at dil"- ferent points along the mandrel.
3. A. gem setting device including a hollow mandrel provided at intervals with setting receiving seats, and means cooperating with the mandrel for clamping a gem in a setting.
1l. fr gem setting device including a hollow mandrel provided at intervals with setting receiving seats of different sizes and having a slot connecting the seats, and means cooperating with the mandrel for clamping a gem in a setting.
5. A gem setting device including a hollow mandrel having a llat face and provided therein with a series of setting receiving seats of dilierent diameters, said mandrel being also provided with a slot connecting the seats, and means cooperating with the mandrel for clamping a gem in a setting.
A gem setting device including a hollow reversible mandrel provided with a plurality of lat faces and having setting receiving seats therein, said mandrel being also provided With slots connecting the seats, and means cooperating with the mandrel for clamping a gem in a setting.
7. A gem setting device including a' hollow mandrel having a flat face and provided therein With a tapered or counter-sunt: seat adapted to receive a setting, said mandrel being also provided with a slot intersecting the seat, and means cooperating with the mandrel for holdin@ a gem in a setting.
ln testimony, that l claim the foregoing as my own, I have hereto ai'TiXed my signature in the presence of two wintesses.
