FEEDER FOR JEWEL-SETTING MACHINES.

SPECIFICATION forming part of Letters Patent No. 519,027, dated May 1, 8

Application filed July 1, l893-' gerial No. 47 .(NO model) the same.

My present invention relates to a meansfor automatically feeding watch jewels to the settings in which they are to be placed and secured by automatic contrivances substantially such as those shown and described in my prior patent, dated July 4, 1893, No. 500,954, for jewel setting machines; and the objects in view are, first, to provide improved means adapted to receive the jewels indiscriminately and in any desired quantity; secondly, to govern and control, by automatic contrivances, the passage of the jewels through the feeder and cause them to be supplied to the settings one at a time; and finally to so construct the feeder that jewels of different sizes can be used therein and supplied to the settings with certainty and precision.

To the accomplishment of these ends, the first part of my invention relates to a hollow receiver, preferably made approximately globular in form, in which the jewels can be placed indiscriminately and provided with an arc shaped outlet opening through grooves or ways in which the jewels can be passed, a vertically reciprocating annular support in which the hollow receiver is mounted to oscillate and carrying a slotted feed plate to which'the jewels from the receiver are adapted to be supplied, in series, as thev receiver is oscillated, and suitable trip or valve,

mechanism which operates as the feed plate comes opposite to the setting when the struct ure is lowered to permit one of the jewels in the feed plate to be forced into the setting by a suitable expelling stud or pin.

The second part of my invention relates to the improved means for controlling the passage of the jewels through the feed plate and for expelling them into the setting, which consists in the combination with the slotted or grooved feed plate, of a spring controlled the novel means whereby the feeder can be adj usted to supply jewels of different sizes. This is attained by making the hollow receiver in sections and employing a spacing ring which conforms to the shape of and is fitted between the sections, and a removable grooved plate fitted between the ends of the spacing ring and the faces of the sections of the receiver.

One end of the slotted or grooved feed plate fits between the ends of the spacing ring and in position to receive the jewels from the grooved plate; and this spacing ring, the grooved plate, and the feed plate are removable and can be replaced by other parts of difierent thickness so that jewelsof different sizes can be properly fed through the receiver and the feed plate.

In the accompanying drawings, forming a part of this specification, I'have illustrated the preferred embodiment of my present invention, in which Figure 1 is a perspective view of my improved jewel feeding mechanism, showing the revolving wire Adesigned to form the setting in which the jewels are to be placed, and an endwise movable spindle P of my jewel setting machine by which the expelling plunger P is actuated to force the jewel into 1ts setting in the revolving wire, A. Fig. 2 is a vertical sectional view on the line 00-00 of Fig. 1. Figs. 3 and 4 are detached viewsof reverse elevations of the removable feed plate, and Fig. 5 is ahorizontal sectional view on the plane indicated by the dotted line yy of Fig. 3 taken through the lower part of said feed plate to show the valve and expelhng mechanism. Figs. 6 and 7 are detail views of the hollow feeder.

Referring to the drawings, in which like letters of reference denote corresponding parts in all the figures, A designates the revolving wire from which the settingis to be formed and in which the jewel is to be placed, and B is a stationary standard which is provided with a clamp ring 1) adapted to fit around the mouth of the lathe and to be clamped thereon by suitable screws, the revolving wire A running through the clamp ring.

The stationary standard B is provided on one side or face with the vertical guide way 0, preferably dovetail in cross section, and in this way is fitted the reciprocating slide D, shaped to conform to the guide way. This slide is designed to sustain the receiver, the feed plate, and the trip or valve mechanism, and this slide is reciprocated vertically at proper intervals by means of a cam (not shown) which operates the lever cl pivoted to the outer end of a rigid arm d fastened to the slide. The upper end of this slide carries an annular support 6 which is rigid with the slide, and in one face of this slide is formed a groove 2 which extends from the lower end of the slide clear through the lower part of the annular support.

F is the hollow receiver which is fitted snugly within the annular support e and is adapted to oscillate or rock therein fora limited distance. This receiver consists of two sections fif, made in the form of concavoconvex disks each having an annular flange f and a hubf These sections are fitted on a rock shaft G with their concave sides facing each other and their flanges f in position to bearoneuponthe other; and onesection of this receiver is permanently fixed to the shaft in any preferable way while the other section f is detachably clamped thereto by means of the binding screw g having a head or handle 9 the screw working in a threaded socket in the hub of the section. The upper edge of one sectionfis cut away to provide an opening h in the receiver through which a quantity of jewels can be placed in the chamber of the receiver, and the lower inner sides of the sections are inclined toward each other at h to direct the jewels properly to the outlet opening from the receiver.

Between the lapped flanges f of the sectional receiver is interposed aspacing ring H which is of such thickness that the sectionsf are spaced apart a distance sufficient for the jewels to pass through the opening or space formed between the fiangesf, and a series of these spacing rings H is employed which vary in thickness according to the thicknesses of the jewels to be supplied through the receiver. This opening strip conforms to the shape of the flanged receiver, and in the preferred embodiment of the invention, shown more clearly by Fig. 6, the spacing ring is made from a flat piece or plate of metal with a segment of said spacing ring out outto provide an opening or space '1: in one side thereof, the extremities of the ringlike strip being undercut or beveled as at 2". Acountersunk recess j is formed in the inner face of one of the sections f, and in this recess is fitted a grooved and ribbed plate J, the ends of which are beveled as shown. This plate is fitted 1n the recess j, practically flush with the faceof the section, but its exposed face is formed with a series of transverse parallel ribs 7 forming a like series of channels or grooves 7c; and a series of these channeled plates J is provided and made interchangeable, the channels in the plates varyingin size according to the sizes of the jewels to be supplied from the receiver to the feed plate. The spacing ring H is confined between the flanges of the sections by pins fixed on one sectionf passing through apertures in the ring H and theother section f, but this particular connection is immaterial and can be changed at pleasure; and the channeled plate J is fitted between the beveled ends of the spacing ring, whereby a discharge opening J is provided in the lower side of the receiver between the flanges of the sectionsfand between the extremities of the spacing ring to permit the ewels from the channeled plate to pass to the groove or slot in the feed plate. It will be noted that the binding screw can be released to permit one memberfof the receiver to be ad usted away from the other member, for the purpose of having ready access to the ring H and the plate J, and that the ring and plate can be detached, other rings and plates substituted therefor, and the loose receiver member f again adjusted to close the receiver and confine the spacing ring H in place by tightening the binding screw, whereby spacing rings and channeled plates of different sizes can be readily adjusted and the receiver adapted to feed jewels of different sizes.

The rock shaft G by which the receiver is oscillated isjournaled in a fixed bearing on an arm K rigid with the upright slide D, and said shaft has the stop collar 7c and a crank arm K, to which arm K is pivoted a link (not shown) operated by a suitable cam (not shown) for oscillating the receiver at the proper intervals.

L is the removal feed plate whichlis fitted in a dovetail groove or way 6 provided in the outer face of the slide D, the upper end of said feed plate fitting close to the oscillating receiver F and the lower extremity of said plate extending and protruding below the slide D on which it is carried. The feed plate L may be made in one piece, or it may be composed of two or more sections; and said feed plate has a groove m formed on its inner side in position to receive the jewels from the channeled plate J and the opening J in the receiver. If the feed plate is made in sections, the groove is formed in the upper section and a slot is made in the lower section as shown by Figs. 3, 4 and 5; or the slot may be made nearly continuous throughout the feed plate. The lower protruding end of the feed plate has a solid foot piece m attached to or made a part of the plate across the slot or groove m therein, and in one end of this foot m is formed an arc-shaped recess n in which is fitted a segmental gate or valve N which is pivoted at n to the feed plate.- This gate or valve N has a lateral stud or pin 0 against which bears an arm of the spring 0 attached to the foot m, which spring normally forces the segmental gate or valve over the lower end of the groove or slot m to prevent the jewels from escaping from the feed plate; but this feed plate and the valve are so arranged relatively to the jewel setting or the revolving wire A that, when the device is lowered into position, the gate N will strike against the wire or setting A with sufficient force to overcome the tension of the spring 0 and thus lift the valve to permit the slot or groove m in the feed plate to come opposite to the cavity in the setting A whereby a jewel in the groove or slot m can be forced, by the expelling stud or pin P, into the setting. This expelling stud or pin P is guided by a bracket 19 fixed to the opposite side of the feed plate, and said stud or pin is normally held in place, out of the path of the jewels, by means of a tension spring p, also attached to the feed plate, the other end of the expelling stud being extended or projected through the bracket p so that it is adapted to be moved endwise at the proper time by means of an endwise spindle'P indicated in Fig. l of the drawings, said spindle being mounted to reciprocate in a revoluble carrier forming a part of a jewel setting machine of the class shown and described in my prior patent hereinbefore referred to. A series of these feed plates L is provided to fit in the groove or way in the reciprocating slide D, the slots or grooves in the feed plates being made in different sizes according to the diameters of the jewels to be supplied, each feed plate being equipped with an automatically tripped gate and the expelling stud; butI would here remark that I do not strictly limit myself to the precise form and arrangement of automatic valve and expelling stud herein shown and described as the preferred embodiment of this improvement.

The operation may be briefly described as follows:A spacing ring H and channeled plate J of the proper size are adjusted between the members of the receiver, and a feed plate L having a groove or slot in of the size to receive the jewels is adjusted in the guide or way 6 of the slide D, after which a quantity of jewels is placed by hand in the receiverF through the opening it therein. The machineis now started to revolve the cams by which the receiver F is oscillated, and the slide 1) reciprocated with its attached parts,

J, and when a jewel is discharged from the plate L' the remaining jewels are fed through the plate L by gravity and another jewel from the channeled plate J is supplied to the feed plate L so that jewels are constantly supplied from the receiver to the feed plate. When the slide D and its attached parts are lowered, the lower edge of the gate or valve N impinges against the wire or jewel setting A and is raised thereby to permit the setting A to come opposite to the groove or slot m in [the feed plate; the spindle of the jewel setting machine is now advanced to move the plunger P and force a jewel from the plate L into the cavity of the setting after which the spring 19' returns the plunger P to its normal position and the slide D is raised so that the spring 0 returns the valve N across the slot or groove m to prevent the jewels from escaping out of the lower end of the slot or groove'm in the feed plate.

I am aware that changes in the form and proportion of parts and details of construction of the devices herein shown and described as an embodiment of my invention can be made without departing from the spirit 'or sacrificing the advantages thereof, and I therefore reserve the right to make such changes and alterations therein as fairly fall within the scope of the same.
