LEE W. ROWLAND, 0F WINDOM, MINNESOTA.
STONE-SETTING- TOOL.
Application filed August 31, 1925.
The present invention relates to an improved stone setting tool adapted especially for use by jewelers while working upon the mountings of precious stones or jewels in finger rings. The tool is designed for employment with the standard type or form of jewelers lathe, and it is set in position, in combination with the finger ring clamped thereon, and trued between the headstock and tailstock of the jewelers or watchmakers lathe, in order that the jeweler may have ready access to all parts of the ring while repairing the ring or its mounting or re-settin g stones or jewels.
By the utilization of the tool of my invention the finger ring is supported on and clamped rigidly, with contact points inside the ring, to the tool in such position as to facilitate the required operations on any of the usual forms-of finger rings and their mountings.
The invention consists in certain novel combinations and arrangements of parts as will hereinafter be more fully described and claimed. In the accompanying drawings I have illustrated one complete example of the physical embodiment of my invention in a machine tool wherein the parts are combined and arranged in accordance with the best mode I have thus far devised for the practical application of the principles of my invention. A set of bushings with various forms of centering heads is also illustrated in thedrawings as a part of the equipment of the tool.
Figure l is a view showing the tool and ring supported thereon in connection with a jewelers lathe.
Figure 2 is an enlarged plan view of the tool detached from the lathe and showing a finger ring clamped therein.
Figure 3 is a view at right angles to Figure 2 with the operating parts of the tool in section and the finger ring indicated in dotted lines.
Figure at is an end view of the tool as seen from the right in Figure 2.
Figure 5 is a view of the adjusting nut detached from the tool.
Figures 6, 7 and 8 are perspective views of bushings with different forms of centering heads thereon for use with various types of mountings or settings of rings, said bush- "ings being selectively interchangeable for use on the tool.
In order that the general assembly and Serial No. 53,578.
relation of parts may readily be understood I have indicated in Figure 1 the parts of a jewelers lathe sufficient to show the manner of truing up the finger ring R between the headstock 1 and tailstock 2 of the lathe, the chuck 3 of the headstock being used as asocket for the reception and support of the tool which is connected thereto by slipping the stud 4 of the tool into the socket or chuck. The stud here shown is rounded with 'a smooth surface and it may be clamped or secured in the chuck in usual manner, or the stud might be screw threaded and screwed into the socket if desired.
The crown C of the ring, which is here shown in conventional form of the basket type, is clamped true and in symmetrical alinement with the axis of the lathe between the chuck and the tail stock.
The stud 4 is provided with an enlarged round head 5 which is fashioned with a transverse notch 6 for the entrance of the ring, and the notch is undercut or recessed as at 7 for the reception and retention of the ring when clamped and supported on the tool.
The recessed notch is of a size and shape to receive various types and sizesof ring bodies and the head is adapted to assist in retaining the ring in rigid adjusted position for the operations of the jeweler.
In addition to the stud the head is provided with an axial screw thread-ed stem 8 upon which is carried an adjusting and clamping nut 9, which when the ring is supported on the toolis located within the opening of the ring as indicated. The nut is fashioned with a knurled flange 10 to facilitate turning it on the threaded stem, and upon the nut is carried a removable cylindrical bushing 11 having a round, open center head 1.2 of reduced diameter which is adapted to contact with the rear portion of the crown of the ring. The centering head 12- of the bushing is retained in frictional contact with the crown of the ring while the nut may be turned loosely within the bushing, to the right or left on the stem 8 as indicated in Figure 3.
In attaching the ring to the tool, the body of the ring is first slipped into the recessed notch of the head with the crown portion C of the ring in approximate alinement with the longitudinal axis of the too-l, the nut 9 and its loose bushing being retracted or in position adjacent to the head 5 of the tool.
lVith the ring held in approximate position, the nut is turned on the threaded stem to bring the centering head of the bushing in contact with the rear of the crown portion C of the ring. Then by further turning the nut the bushing is retained by frictional contact with the ring and the action or" the nut clamps the ring in symmetrical position, in alinement with the longitudinal axis of the tool or the axis of the lathe. In this manner the ring is clamped by Contact with two parts of its interior leaving the exterior portions and mounting unobstructed for the convenience of the jeweler in working about the ring.
lVith the stud & sipped into the chuck 3 of the head stock, the tail stock 2 may be utilized for truing and centering the ring in proper position. After completion of the work on the ring the latter may be detached from the tool by first turnin the nut and its loose bus-hing toward the head 5 to withdraw the centering head 12 from the crown portion of the ring, and then the crown portion of the ring may be grasped by the fingers and the body of the ring slipped out of the recessed notch of the head.
For the accommodation of various types and sizes of ring mountings or settings I provide a set o't selectively interchangeable and removable bushings that may beused when required. Thus in Figure 6 I show a bushing 13 with a square centering head l t; in Figure 7 the bushing 15 has an oblong centering head 16; and in Figure 8 the bush ing 17 is fashioned with an oval or elliptic shaped centering head 18. In these views the bushings are shown with a closed hollow head to accommodate the threaded stem as the adjustable nut is moved on the stem, while in Figure 3 the bushing 11 is shown with an open centering head 12 to accommodate the end of the threaded stem when required. These changes, and other alterations within the scope of my claim may be made without departing from the principles of my invention.
One of the most important features of my invention resides in the construction of the head which is formed with a recess or notch with a wide entrance leading to an undercut portion having an upper inclined wall, this construction forming a seat to receive and lock the ring in the head and prevent move ment or displacement of the ring.
Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent is The combination with a head having a stud and an alined threaded stem, of a flanged nut on said stem. a bushing having a centering head on said nut for contact with a ring and means on the head for coaction with said bushing in supporting said ring said means consisting of a notch in the head and an undercut communicating portion forming a seat and retaining means for the ring.
In testimony whereoi I hereunto attix my signature.
LEE W'. ROIVLAND.
