SPECIFICATION forming part 0f Letters Patent NO. 500,954, dated July 4, 1893.

Application filed August 27, 1892. Serial No. 444,253. (No model.)

To all whom t may concern,.-

Be it known thatI, WILLIAM RUNDQUIST, a

citizen of the UnitedStates, and a resident of Elgin, in the county of Kane and State of Illinois, have invented certain new and useful Improvements in J eWel-Setting Machines for Watch-Jewels; and I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The nature of this invention consists in mechanism for forming a setting for Watch jewels, introducing the jewel therein, and in finishing the ljewel and setting, the several mechanisms being all arranged for automatic and successive action.

With these ends in view, my invention consists of the novel combination of devices, and in the peculiar construction and arrangement of parts, as will be hereinafter fully described and claimed.

In the accompanying drawingslz-Figure 1 is a side elevation of a machine constructed in accordance with my invention. Fig. 2 is a plan View of the same. Fig. 3 is a longi tudinal vert-ical sectional View on the plane indicated by the dotted line -x of Fig. 2. Fig. 5 is a front elevation. Fig. G is a detail View of the head of the cutting spindle. Fig. 7 is a similar View of thehead ofthe jewel burnisher. Figs.

8 and 9 are detail views of the truing head.

Fig. 10 is a detail' view of the cutter for truing the jewel setting; and Figs. ll, 12 and 13 are detail views of Vthe jewel feeding mechanism.

Like numerals of reference denote corresponding parts in all the figures, referring to whichl designates abaseorsupporting bed which is firmly secured ou top of a suitable work table or bench 2, and to this supporting bed l is firmly and rigidly secured a tubular casing or cylinder 3. Within the cylinder or casing 3 is fitted a revoluble cylindrical carrier 4 which projects slightly beyond the ends of the casing 3 and whichvis provided-at its rear end with a projecting annular fiange 5, that abuts against the end of the'casing 3 and in the periphery of which is-,form'ed-aseries of notches or recesses 6. Through a slot in the upper' surface or top 2 is fitted a lever 7 and on said lever, near its upper end, is fulcrumed a transverse lever 8, one end of which is connected to a casing 9 fitted to slide on the flange 5 of the cylinder 4. The casing 9 is, preferably, fitted on the carrier 4 by means of lips 9', formed integral with the sides of said casing, which flanges or lips take over kthe inner edge of the flange 5 and enable the carrier to be revolved without moving the casing 9, if desired. Within said casing 9 is arranged a dog or detent 10 which fits in a suitable way or groove in the case 9 and which is adapted to beprojected into one of the notches 6, in the flange of the carrier 4,

by a coiled pressure spring l0 arranged with'- in the 0asing9 below the dog therein.

The cylindrical-carrier 4 is arranged to be locked rigidly in any desired position by means of a locking detent 1l fulcrumed be-y tween suitable lugs attached to the fixed casing 3 and provided at one end with a laterally projecting finger or stud 12 adapted to take into one of the peripheral notches 6 in the flange 5 of the cylindrical carrier. The cylindrical carrier is kept stationary-or fixed by a flat spring 13 attached at one end to the casing 3 and bearing, at its free end, against the underside of the locking detent 11, below the fulcrum thereof, to keep the finger or stud 12, in one of the notches 6. The free-end of the lever S is bent at right angles to its length and extends across the lower portion vof the locking detent 1-1 and when the lever 7 is oscillated, by any suitable means, the casing 9 `will be moved onv the flange 5 and the dog,

l0, therein, will take into one of the peripheral notches 6 and operate to turn the cylindrical carrier one step or notch, the finger or stud l2 being elevated out of engagement with the fiange 5 by pressure of the hook portion of the lever 8 on the lower end thereof. When the lever 7 has reached the limit of its forward movement and starts back to its original position, the casing 9 will be moved on the flange 5, the dog 10 having its upper surface inclined to permit of such rearward movement; and, asl soon as pressure is removed from the lower end of the detent 1l such lever will be returned to its normal p0- sition and the stud or finger 12 forced into one of the notches 6 by the action of the spring 13.

Through the cylindrical carrier4 extends a series of spindles 14, 15, 16, 17 and 18, and these spindles project slightly beyond the ends of the cylindrical carrier. On` each of these spindles is fitted a collar 19, which is held in position on the spindle by means of a set screw 19. A finger 20, formed integral with each collar 19, extends through one of a series of longitudinal slots 21 formed in a tube 21 which is rigidly attached to the rear end or head of the cylindrical carrier 4. The outer end of the tube 2l is closed by a plug .312 and within said tube, in advance of the lingers 20, is arranged acoilcd spring 22,and between said fingers and the rearend of the coiled spring 22 is situated a block 22so that as either of the` spindles is moved forward, by means to be hereinafter pointed out, the spring 22 will becompressed, and when pressure isremovedfrom the rear end of said spindle the spring 22 willreturn the spindle to its normal position.

In a suitablesocket formed in the outer end of the spindle 14, is fitted a cutter 23 which is held firmly in place by means of a set screw 23. This cutter is adapted to form in one1 end of a wire 24 a socket or recess adapted to receivea jewehsaid `wire 24 being rotated and.` carried by alathe inthe ordinary manner.

The forward solid` end of the spindle 15 is conical or tapered as shown, and said spindle is adapted, when the cylindricalcarrier is turned tot bring themsame in line.` with thepro- .jecting end of the wire 24,r and it is moved forward by means totbe hereinafterdescribed, to force a jewel carried by a suitable holder, into the socket or recess previously formed by the cutter 23 inthe end of the; wire 24.

In the forward end or head of the spindle 16, (which head isenlarged)is formed: a groove or way 25 in` which is fitted a movable block 25.` The block 25' is held in position in the groove or way formed in the head of the spindlereferred to, by a screw 26, which is screwed into such` head and has its enlarged head extending into agrooveor recess formed in the rear side of the movable block 25. A` burnisher 26 is fitted in asocket formed in the 4outer face of the block 25' and is held firmly in` such socket by a set screw 27. The burnisher is preferably made in` they form shown in Fig. 7, in which it consists of a blunt cen- `tral spring pressedpin 27 and acutting or `burnishing edge or point 23 arranged slightly in rear of the blunt pointof thepin 27 and extending at an acute angle to` the length of said pin. When the spindle 16 is broughtl in line with the Wire 24, and isprojected forward, the blu-nt end of the pin 27 bears against the center of the jewel which has been previously secured in the socket, formed in the end of the wire by the cutter 23 on the spindle l5, and keeps the jewel in place in the cured another cutter, preferably by having its ystem or shank seated in a socket formed in 'the end of said spindle.

This cutter of the spindle 17, consists, as shown in Figs. 8 and 9, of a body 29 provided with an integral stem or shank 29" designed to be inserted into a suitable socket formed in the forward end of the spindle 17. On the upper side of the body 29 is centrally pivoted a circular cutting blade 30, provided with a series of peripheral teeth 30. The central pivot of the blade 30 extends through a slot inthebody 29 and on said pivot pin, near the lower end thereof, is rigidly secured a ratchet wheel 31. Below the wheel 31 is fulcrumed a bell crank lever 32, the shorter annil 32 of which is connected with the. front end or headof the cylindrical carrier 4 by a coiled spring 33. To the body 29, in rear of theshort arm of thelever 32, is secured a` downwardly projecting pin or stud 33 adapted to4 limit the play or movement of the bellcrank in one-direction. To the front end or head of the cylindrical carrier is attached a projecting pin 34 arranged in the path of the long arm of the bell crank., When-thespiudle 17 has been brought into-line with the Wire 24 and` projected forward the required distance, thecu-tting blade 30 will operaterto remove from the end of the wire the` surplus materialI which has been raised up or formed by the action of the burnisher carried by the spindle 1G. As the spindle 17 is withdrawn to its normal position, the longer arm of thebell crank 32 comes in contact with the fixed pin 34 and as the spindle moves rearwardly the said arm of the lever 32 Wil-l be forced forward and a pawl or dog 34 thereon takes into the teeth of the `ratchet wheel4 31 and turns the same, thus bringing into operative position another tooth on the cutting blade 30. When the spindle 17, is moved forward agaiintlie coiled spring 33 operatesto return the lever to its normal position.

The head or forward end of the spindle 18 is similar tothe head of the spindle 16; and

is provided with a movable block 35. A

trimming blade 36 is held in place in a socket formed in the movable block 35 by means of a. set screw 36. The blade 36 operates when brought to bear against the end of the wire 24 to trim or reduce such wire to the desired size to form the setting of the jewel.

. At the` forward end or head of the cylindrical carrier 4, betweenthe spindles 14, 18, is arranged a stationary stud 37 provided atits `outer free end with an` internally threaded socket in which is fitted a screw 37. The endof the wire 24 abuts against the screw 37 and said screw can be adjustedto vary the length of said wire from the lathe.

3S designates a lever which Works through a longitudinal slot in the top of the table 2.

On said lever, near the upper endthereof, is pivotally mounted a pushing nger38 provided in its forward free end with a socket which, when the lever 3S is oscillated, by suitable mechanism, and the upper end thereof moved forward, receives the rear end of one of the series of spindles 14,' 15, 16, 17,l 18. The spindle-which is in line with the pushing finger 38 is moved forward as such linger advances, and the implement carriedv by said spindle is brought into proper position for operation. When the upper end ofy the lever- 38 moves `rearwardly the spindle with which it is in contact is also returned to its normal position by the action ofthe spring 22.

Over the rear ends of the spindles 16 and 17, carrying the burnisher 26 and-cutter 30, respectively, are fitted sleeves 39 which are closed at their rear ends and held in placev on the spindles by screws 40 which extend' through longitudinal slots formed in said sleeves. Within the sleeves 39, between'the closed rear ends thereof and the ends of the' spindles, are arranged coiled cushion springs 39. The object of this construction is to prevent the burnisher or the cutter from being pressed against the jewelwith sufficient force to damage or injure the same.

In the rear ends of all of thelongitudinally movable spindles mounted in the carrier 4, I preferably secure a screw .40, the head of' which is of such size as to fit snugly in the socket in the forward end of the pushing finger 38 andsaid screws can be adjusted to lengthen or shorten said "'spindles.

To the fixed casing/3, at the forward end thereof, is rigidly'secured a bracket 4l and v through asuitable aperture formedv in the upwardly extending arm of said bracket is passed a pivot lug or 'stud 42 of an'arm 43'. In the rear face of the arm 43, below the pivot point thereof, is formed a longitudinal guide way in which is fitted a yjewel carryingslide 44,l which is held in position within the guide way in the arm'43 by a pin 45. In the inner face of the slide 44 is formed a groove or channel 44 designed to receive a number of jewels of the proper size to lit in the socket which is formed in the end of the wire 24 by the cutter 23; and 4the lower end of this groove or channel communicates with a transverse channel or groove formed in the front face of the arm 43. This latter channel is of greater di-A ameter at its upper than at its lower end and init is fitted a block or slide 45' which is held in place by a'iiat spring arm 46 secured at one end to the arm 43 and extending across the upper end'of said block 45.

To the outer face of the slide 44 is attached a short outwardly projecting sleeve 46', the inner end of which communicates with the longitudinal channel 44 in rearof thejslide 44; and in said sleeve 46 is fitted a pin47- provided with an enlarged head. On the pin' 47, between the head thereof and the end of the sleeve 46', is formed an annular flange 47.`

The p in 47 is normally held out of the channel 44 by means of a flat spring arm 4S which is attached at one end to the outerface of the slide 44 and has itsfree Vend bifu'rcated and extending on opposite sides of the pin 47, be-

tween the enlarged head thereof and the annula'r flange 47. In the upper end of the longitudinal guide way in the arm 43, and bearing against the upper end of the slide 44, is'arranged a coiled spring 4S.

In advance and at one side of the axially turning vcarrier 4 and the supporting fixed loasing3 thereof, is arranged another lever 49 whichis fulcrumed between lugs 49 secured on the top of the table 2, and said lever extends down through a short transverse slot formed insuch top. To the upper end of the lever 49 is attached a finger 50 which Vextends upwardly and laterally from the lever 49'and has its outer end bifurcated. In suchI bifurcated end is journaleda roller 5l provided with a peripheral groove in which the lower edge of the arm 43 fits. The arm 43 is kept pressed against the rollerl 51 by means of a spring 52 which is `coiled around the pivot stud`42 and has one end extending across the' upwardly extending arm of the bracket 4l on the fixed casing l3 and its other` end extending across the upper side or edge of the arm 43 above the pivotal point of the same. The spring 52 serves to keep the upper end of the varm,-'43, elevated and the jewels carried by the slide 44 near the lower forward end thereof.

Below the top of the table 2 is preferably arranged a longitudinal sha-ft 53, which is journaled in suitable bearings and provided with suitable driving means, not shown. On the shaft 53 are rigidly secured three disks 54, 55, 56. In one face of. the disk 55is formed a cam groove having as many offsets as there are notches in the liange 5 at the'rear end of the cylindrical carrier 4, and in said groove rides a guide roller attached to the lever 7 and which, as the shaft 53 is rotated, causes the Vlever 7 to oscillate and rotate the carrier with a step by step motion to bring the different implements carried by the spindle suc cessively in line with the projecting end of the wire 24. The other disk 54 on' the driving shaft is also provided in one face with a cam groove in which rides a roller attached to the lever 49 to oscillate the same as the shaft-53 is rotated and thus alternately raise the rear upper end of the arm 43.l The remaining-disk 56 is provided with a' proper cam surface against which the lower end of the lever 38 bears and as the shaft 53-is .rotated the lever 3S is scillated and the spindle in line with the finger`38 is moved yforward to bring the implement carried atv its forward end into operative position.

A spring,382, is arranged below the top of the support, 2, and one end of saidv spring is attached to the rear wall of said support 'and the other end to the level-,38, above the fulcrum thereof.v

The operation of my invention is as fol- IIO lows: The wire 24, or the material from which it is desired to form the jewel settings, and which is carried and adapted to be revolved by a suitable lathe in the ordinary manner, is advanced until the free end thereof cornes in contact with the end of the fixed stationary stud 37. The shaft 53 is then slowly revolved and as the lever 7 moves forward, the dog or detent 10 takes into one of the notches 6 and turns the cylinder one step to bring the spindle 14 in line with the wire 24. As the spindle 14 reaches its proper position, the lever 7 moves back to its normal position and the casing 9, attached to such lever, moves on the flange 5, the inclined upper end of the dog 10 permitting the same to free itself from the notch 6; and the lever 38 is moved forward. As the lever 38 moves forward, the rear end of the spindle 14 enters the socket in the free end of the finger 38 and said spindle is moved endwise until the cutter carried at the forward end thereof contacts with the end of the revolving wire 24 and speedily forms therein a socket of proper dimensions and form to receive a jewel. As the lever 7 starts forward again to rotate the carrier 4 another notch or step, the lever 3S and spindle 14 regain their normal positions by action of the springs 382 and 22, respectively, and the spindle 15 is brought into line with the wire 24. As the carrier is turning to bring the spindle 15 into operative position, the lever 49 is moved and the upper end ofthe arm 43 elevated. As the upper end of the arm 43 is raised, the lower end of said arm is depressed and the projecting end of the wire 24 contacts with and moves the block 45 longitudinally to expose the lower portion of the groove or way in which it is fitted and the lower end of the longitudinal jewel receiving channel 44. As the block 45 is raised to thus expose the jewel receiving channel 44, the spindle 15 is moved forward by the lever 38 and the outer end of said spindle bears against the enlarged head of the pin 47 and forces said pin forward. The forward motion of the pin 47 forces a jewel from the channel 44 into the socket, previously formed in the end of the wire 24 by the cutter 23. As the lever 49 returns to its normal position, the upper end of the arm 43 is depressed by the action of the spring 52 and as the lower end thereof moves upwardly the block or slide 45 is returned to its normal position by the spring arm 46, the pin 47 having been withdrawn, as soon as the spindle 15 has been moved rearwardly out of contact therewith, by the spring arm 43. The

- carrier 4 is then rotated to bring the different able the channel 44 therein to be fitted with jewels, by withdrawing the pin 45.

From the foregoing description and dra-wings it will be seen that I have provided a simple, and compact machine for automatically preparing the jewel setting, securing the jewel in place therein, and finishing the setting.

I am aware that changes in the form and proportion of parts and details of construc-` tion of the devices herein shown and described as an embodiment of my invention can be made without departing fromthe spirit or sacrificing the advantages thereof. For instance although I have described one form of mechanism adapted to operate my machine from a common driving shaft, yetI am aware that many other forms can be substituted with equally good results, and I do not therefore wish to be understood as intending to limit myself to the specific construction and arrangement of parts herein shown and described.
