J EWEL-SETI'ING MACHINE.
Application filed May 18,
To all whom it may concern:
Be it known that I, LEMUEL E. GARNETT, a citizen of the United States, and resident of the city of Tacoma, county of Pierce, and State of \Vashington, have invented certain new and useful Improvements in Jewel-Setting Machines, of which the following is a specification.
This invention relates to improvements in jewel setting machines, and more particularly to machines of that character especially adapted to the work required in the making or repairing of watches; the principal object of the invention being to provide a machine which will be simple and efiicient in its operation, durable in construction, which will be relatively inexpensive and which will, by its use,.greatly expedite the work for which it was intended.
It is also the object of the invention to provide a machine 01 the above character, comprising a lathe or chucking spindle, wherein pieces used for jewel mountings, or the like, may be held in position to be worked upon. and to provide a revoluble turret whereon various forms of cutting,
luirnishing or polishing tools are mounted in positions to be moved by selective adjustment and rotation of the turret into working relation with the pieces that'may be held in the lathe chuck.
further object of the invention resides in the provision of the several features of adjustment for properly setting and adjusting the various tools carried by the turret.
In accomplishing these and other objects of the invention, I have provided the improved details of construction. the preferred forms of which are illustrated in the accompanying drawings. wherein--- I Figure 1 is a side view of a 'ewel setting machine constructed according to the present invention.

1920. Serial No, 382,367.
Figure 7 is an elevation of the table and a cutter, looking in the direction of the arrow in Figure 6, showing the cutter adjusting screw.
Figure 8 is a detail sectional view of the turret head, showing the screw whereby it is locked to the adjusting plate.
Referring more in detail to the drawings, wherein like reference numeralsdesignate like parts 1 and 2, respectively, designate upper and lower, horizontally disposed, circular tables which are rigidly spaced apart by three equally spaced posts 3, and are supported at a desirable working height by legs 4 which are fixed to the lower table and at their ends are equipped with screws 5,
whereby the device may be secured to a table or other working foundation.
Revolubly mounted at its opposite ends in the tables 1 and 2, is a lathe spindle 6, provided at its upper end with a conically tapered shoulder .7 which seats against an opposing shoulder in a central opening 8 in the table 1, and at its lower end has a downwardly facing, coni'cally tapered shoulder 9 which seats within a conicallytapered opening in a nut 10 threaded cent-rally through the table 2, and adjustable therein to take up any wear that is incidental to use of the machine, and which is equipped with a lock nut 11 that maybe tightened against the table to retain the adjustment.
The spindle 6 has a longitudinal bore 12 therein. wherein the shank of a tubular chuck 13 is extended. At its upper end the chuck has a longitudinally split head 1 1 which seats against a. conical bore 15 at the upper end of the spindle bore 12, and at its lower end is threaded into a holding stem 16 that is projected into the spindle bore. with a wheel or head 1'? fixed thereon, which seats against the lower end of the spindle 6 and which may be turned to loosen the chuck. or to draw it inwardly to contract the split head against a piece, or wire that may be extended into the chuck, to hold the same while being worked on.
Mounted on. the spindle is a grooved pulley wheel 20 over which a belt 21 may be extended and driven in any suitable manner to revolve the spindle for the purpose 0t turning or cutting pieces heldby the chuck.
Extending laterally from the table 1 is bracket 22 having a vertical portion 23 and a: forwardly directed arm 24, overlying the table, and supported on the arm 24: in
block laterally. Pivotally fixed superimposed and concentric relation, is a circular plate 25 and a turret plate 26. A bolt 2'? is extended upwardly, through the arm, and centrally through the plate 25 and turret to support the same revolubly on the bracket; the turret, which is supported on the plate, has a boss 28 on its upper side which serves as a hub for the bolt, andv the latter extends above the boss and has a nut 29 threaded thereon to hold the turret substantially in working position.
Mounted in the turret, at equal radial distances from the bolt, about which it revolves, are a plurality of tool carrying de vices 30, each of which may, on revolvingthe turret, be brought into alinement with the axial line of the spindle 6 to position tools carried thereby in working relation to pieces of metal, wire or plates that may be held by the chuck head 14;, or on the base plate 2. The tool holding devices 80 comprise tubular members 31 that are fixed to extend vertically through the turret with their lower ends open and their upper ends closed by caps 32. Within the tubular members 31 are blocks 33, each provided with a threaded stem 34; that extends upwardly through an opening in the tube cap and at their upper ends have heads 35 thereon whereby the stems may be lifted to move the block upwardly against the pressure of spring 36 located within the tubes and hearing against the caps and block. 1
Each block 33 has a tapered tool socket 38 in its lower end for receiving a tool, such as the cutter 39, the burnisher 40, polisher 4L1, or other desirable tools.
Threaded onto the stems between tr e caps 32 and heads 35 are nuts l3, which may be adjusted to limit the downward movement of the tools to a certain distance. These nuts, as is shown in Figure 3, are. graduated in degree marks, which may be observed when adjustment is made and will serve to facilitate re-setting or adjustment.
Extending downwardly from the rear edge of the plate 25 is an arm l5having laterally turned end 46,. as shown in Figures 1 and 1, and fixed beneath the bracket an arm 4'? which extends rearwardly beneath. the arm t5, and at its outer end an upturned, bifurcated portion 18, wherein a block 49 is transversely adjustable; the block being slidable on a cross rod 50 and threaded onto an adjusting screw 51, which may be turned by a head 52 to adjust the by a pin. 53 to the underside of the block 4-9, is a head 54:, and slidable therein is a pin which at its inner end is threaded into the out-turned end 46 of the arm 45.
Threaded downwardly through. the turret plate 26 is a thumb screw 56, having a tapered inner end 47 which is adapted to seat in any one of a plurality of tapered sockets 70, that" are threaded After a desired adjustment of the block l9 has once been made, it can be locked by set screws and 61, that are threaded inwardly from opposite sides of the bifurcated end of the arm 47.
Mounted on the table, or plate 1, is a gauge bar 60, which is pivoted at its inner end to the table by a pivot pin 61, and at its opposite end is adapted to move toward or from a stop block 62 fixed on the forward edge of the table. The bar has a raisedicentral portion 63, which permits it to overlie and move freely across plates, or pieces, that may be fixed on the table, as is shown in Figure 6, and at its movable end has aslotted, laterally extending arm 64, through which, a set screw 65 is threaded into the edge of the table to hold the bar at any adjusted or set position.
In this construction, the distance from the pivot pin 61 to the center of the spindle chuck is equal to the distance from the chuck to the stop block, and when the swinging end of the bar is engaged with the block, its inner ed designated by numeral 66 bisects the axial line of the spindle, for a purpose presently described.
Mouuted within openings 67, cut in the table-2, are frames 68, pivotally mounted at one edge, as by the pins 69, and adjustable vertically at their opposite edges by screws through brackets 71 fixed to the under side of the table. Slidable longitudinally within these frames to-- ward and from the spindle,.are cutter 'bars 72, which are adjusted by means of screws 73 fixed revolubly in the frames and threaded into blocks 74 that are fixed to the cutter bars: The inner ends of these cutter bars may be designed for various forms of cutting and are adjusted horizontally and laterally by manipulation of the screws 7 0 and 73 to act on pieces that maybe mounted in the lathe chuck.
Assuming that the device is so constructed, in using the same for forming a jewel mounting from a piece of wire or thelike, the latter is extended into the chuck and clamped therein with its upper end disposed in position to be operated upon by a drill or other tool carried by the turret. To properly gauge the diameter of opening for any special size of jewelto be mounted, the
jewel is placed between the stop block and end of the gauging bar, and the cutter is adjusted, as is shown in Figure 3, against its inner edge.
Since the distance from the pivot pin 71 to the tool is one half the distance to the position where the jewel is placed, it is apparent that such adjustment of the cutter will provide for cutting or reaming out a mounting that will be of the same diameter of the jewel and the latter can be easily set therein.
After a jewel hasbeen set in the mounting thus provided, other tools are brought into working relation by turning the turret and the jewel can be burnished, polished and made ready for use without removal from the machine.
The cutters mounted in the table 2 can be adjusted as desired to cut off, or trim pieces held in the lathe, or accomplish other work incident to jewel setting operations.
Having thus described my invention, what I claim as new and desire to protect by Letters Patent, is:
