SPECIFICATION forming vpara of Letters Patent No. 659,192, dated october 2`, 1906.

Application led April 2, 1900. Serial No 11,195. lo model.)

To ttZZ whom, it may concer-7e:

Be it known that I, NICHOLAS BARRY, Jr., of Muscatine, in the county of Muscatine and State of Iowa, have invented certain new and useful Improvements in Button-Drilling Machines; and I hereby declare that the follow, ing is a full, clear, and eXact description thereof, reference being had to the accompanying drawings, which form part of this speciiication.

This invention is an improved machine for automatically drilling holes in pearl and bone buttons; and its object is to produce a machine wherein the most delicate buttons can be safely drilled automatically and wherein a number of buttons can be simultaneously operated upon, thereby increasing the capacity of the machine, each button-blank chuck or holder and its coacting drill traveling together, and means being provided whereby the relative positions of the drill and the button blank will be automatically changed during their linear travel, so that the desired num ber of holes in the blank shall be drilled successively and at the proper points, and provision is further made whereby the number of drilling operations performed by each drill upon the blank may be varied and the time required for each drilling operation may also be regulated. Means are also provided for bringing the chucks or blank-holders into position to release the drilled blanks and to receive an unfinished one without necessitating the stopping of the machine, and thereafter the chuck presents and maintains the blank in proper position relative to the drill to undergo the drilling operations. Means are also provided whereby the drills can be set at an angle, so as to drill slanting holes in the blanks, if desired, and various adjustments are provided whereby wear on the parts can be taken up with the greatest nicety. I have also provided simple but eective means whereby' the drills can be readily adjusted in the several drillholders with absolute uniformity and without necessitating trying and fitting of the drills relative to the blank-holders to properly adjust them.

In the accompanying drawings I have illustrated a multiple drilling-machine which embodies the various features of my invention in the best form now known to me, and the principles of the invention can be readily understood from the following description of the said machine. y

Referring to the drawings, Figure l is a front elevation of the machine. Fig. 2 is a rear elevation thereof. Fig. 3 is a vertical longitudinal section. Fig. 4 is a top plan View. Fig. 5 is a horizontal section on line 5 5, Fig. l. Fig. 6 is a horizontal section on line 6 6, Fig. l. Fig. 7 is an enlarged detail view of a drill-holder. Fig. 8 is an enlarged sectional view of one of the chucks. Fig. 9 is an enlarged detail of part D.

A designates a rotary chuck-holder, which consists of a pair of upper and lower disks suitably connected by stays or bolts and provided near their peripheries with openings for the reception of the spindles B, through which pass the chucks O, the chucks being split at their upper ends, as usual,and adapted to receive a button-blank. The spindles are supported on the lower disk and are pressed down by means of springs b, interposed between collars D on the lower end of the spindle and the upper disk, as shown. Preferably the upper end of the chuck O is conical and tapered to engage the correspondinglyinteriorly-tapered upper end of the spindle B, so that when said chuck is raised it will bind in the spindle and lift the latter, and the spring-pressure will cause the closing of the chuck. The chucks extend through the spindles and depend below the holder A and are adapted to ride upon an annular cam or track E, which track is provided with a depressed portion E' at one side, so as to permit the chucks to drop down through the spindle, and in this position the chucks will open and the drilled blank can be removed therefrom and an undrilled blank substituted, this portion E' being long enough to enable the removal and feeding operations to be performed without stopping the machine.

'Phe holder A is mounted upon a vertical shaft F, which is stepped in the central boss of a three-armed spider G, formingv part of the base of the machine, and from the arms of this spider rise vertical shafts g, which are connected at the top by another spiderf, hav- ICO ing a central hub f', in which the upperend of the shaft F is jonrnaled. A worm-gearH is secured on the lower end of the shaft F and is operated by a worm h on a shaft h', which may be driven by any suitable means.

The parts thus far described are substantially similar in construction and operation to like parts shown in my Patent No. 643,587, dated February 13, 1900, and need not be further described herein, only in the present machine I have L,terably employed springs b instead of weights to depress the spindles B.

Above the chuck-holder and attached to shaft F is a plate I, the hub of whichl is adjustably secured to shaft F by bolts i and is keptin correct alinement with the holder A by means of bolts or rods l', depending from the under side of the plate and passing through corresponding openings in the upper part of holder A, as shown. On this disk I is mounted a polygonally-faced drill-holder J, which, as shown, has eight faces corresponding to the number of chucks employed, and to each face of this drill-holder is attached a casting K, which is provided with upper and lowerjournals 7c for a vertically-movable drill-rod L, on which is secured a pulley l', below which is a spring Z', which serves to press the pulley and drill-rod upward and into contact with the under side of an annulus M, which is loosely journaled on the shaft F and is pressed upward by a spring m, the vertical position of this annulus M above holder J being regulated bythe adjustable bolts N, which are tapped through the arms of spiderf and provided with locking-nuts, as shown.

The lower end of the drill-rods L are provided with usual drill-attaching devices by which the drills O may be secured thereto.

It will be observed that there is a drill provided for and opposite every chuck and adapted to coperate therewith in the operation of the machine, and the drill and its related chuck travel together. By diminishing the number of these drills and chucks the capacity of the machine could be decreased and by increasing their number the capacity of the machine would be correspondinglyincreased.

I have found that eight pairs of drills and chucks constitute a very efficient working machine, which will require a rapid operator to feed it when working at its normal speed.

Each casting K is pivotally attached to the holder J by a bolt P and is provided-above this bolt with an opening p, through which projects a stud J', attached to the holder J, and through the casting K at each side of I the opening p are tapped adjusting-bolts p',

which are adapted to engage opposite sides of pin J', and by means of these bolts the casting K and the drill-rod attached thereto can be swung on bolt Pand be set atan angle to the corresponding chuck for the purpose of causing the drill to cut slanting holes in the blank, as is sometimes desired. Fu rther, the holder J is provided with lugs j, which embrace a projection t" ou plate I, and through these lugsj are tapped adjusting-bolts j', by which the drill-holder can be turned on the plate I suliciently to move the drills slightly eccentric to the chucks, so that the drills will operate upon the blanks at'one side of the center thereof and make the holes at the desired positions therein. A blank can be placed in one chuck and its drill adjusted to the proper eccentric position by shifting the drill-holder, as described, and when this one drill is set and the holder is locked all the drills will be set in like positions relative to their chucks, so that all the blanks will be correspondingly drilled. Thus the drills can all be adjusted alike simultaneously and in the most expeditious manner. The drill-holder J is held down on plate I by means of bolts Q, which are passed through enlarged holes in the bottom of the holder, which holes are covered by spring-Washers q. The bolts and wa shers fasten the holder securely to the plate I, but at the same time do not preventits adjustment thereon by bolts j', as above described. On one of the uprights gis journaled a horizontal arm R, which is used in setting the drills. When it is desired to put a new drill or set of drills in the machine, this arm is swung in under the drill-holder and the drills inserted in and fastened to the drillrods while resting on this arm, of course only one drill being set at a time; but by this means the points of all the drills will be on the same horizontal plane, and as the blanks presented by the chucks are always held in the same plane during the drilling operations thereon all the drills will be moved the same distance into the chucks and through the buttons. By this means the drills are set accurately and not by guess, nor is it necessary to lit and tryfthe relative adjustment-of thedrills. After the drills are set the arm R is swung to one side out of the way. The drills will be normally raised out of the Way of the chucks and out of contact with the buttons therein by the uplifting-springs Z', and in order to cause the drills to operate upon the blanks a number of preferably adjustable and removable shoes S are attached to the under side of the annulus M, these shoes being tapered or wedge-shaped and provided with upstanding lugs, through which are tapped bolts S, by which the shoes can be detachably fastened to the annulus. These shoes are attached to the annulus in such positions that as the drill and chucks rotate thereunder the upper ends of the drill-rods come into contact with the shoes, and as the drills travel thereunder said rods are gradually depressed, and during the movement of the drills under the shoes the blank is drilled. When the ends of the shoes are reached, the drills are forced upward by the springs against the ann ulus and permit the chucks to be partly rotated, so as to bring the button-blanks into position for another drilling operation, and when the spindles reach the next shoe they will be again de- IOC) IIO

pressed and the button-blanks again drilled at other points, and so on until the'desired number of holes are drilled in the blanks.

The machine shown is adapted to be used for drilling two or four hole buttons. In drilling two-hole buttons two of the shoes are removed, and they are replaced when drilling four-hole buttons. The time for drilling required by this construction ot' machine can be regulated by the length of the shoes, and by properly tapering the latter the danger of breaking out thin centers of buttons in which the holes are to be drilled may be entirely overcome by causing the drills` to so gradually approach the material as to prevent breakage of the centers.

In the machine shown the drills are rotated on their own axes and the chucks are stationary relatively to the drills during the drilling operations, although traveling orbitally therewith; but after each drilling operations the chucks or blank-holders will be partially rotated,so thatat the next drillingoperation the chucks or blank-holders will be partially rotated on their axes, so that at the next drilling operation the holes will be made at another point in the blank, and this automatic axial rotation of the chucks is accomplished in a very simple manner as follows: The collars D on the spindles B are substantially rectangular, and their outer sides come in contact with an annular flange or ringT, which is fast to the frame of the machine, as shown, and as the chucks travel orbitally around the ring the outer edges of collars D contact with and bear against the ring and prevent rotation of the chucks. Each collar is provided, as shown, with fourupstanding pins, (numbered l to 4E, respectively.) No two of these pins are exactly in line, their arrangement being such that of the two outermost pins the one to the left is always nearer the flange than the one to the right. At proper points around the periphery of the band are located three strikers U U U2, (see Fig. 6,) and as the series of chucks is rotated past these strikers the pin on the left outer corner of the collar D, which pin is always nearest the edge, will come in contact with the striker, and the chuck will be caused to turn one-quarter around the corner of the collar D, projecting through a notch t, t', or t2 in the annulus T opposite the striker to permit and assist in turning the chuck a full quarter until its side comes flat against the innersurface of the ring. These strikers are located intermediate the shoes S, so that the chucks will be turned in the interval between the drilling operations. Three of these strikers are shown, which will successively partially turn the chucks on their axes, as indicated in Fig. 6, and in the machine shown during each complete cycle of movement every chuck will be turned threefourths of a revolution on its own axis each time it is carried around by the holder A. A belt V is led over quartering-pulleys v, at- 'cached to the frame of the machine, and. then around pulleys c', journaled on the two uprights g, as shown, the section of the belt between the pulleys v contacting with the pulleys Z on the drill rods or spindles and rotating those drills whose pulleys come in contact with this section of the belt. Thus the drills will be rotated at the proper times, but will not be rotated while passing the feed side of the machine. This drive is substantially like that described in my Irjjnresaid patent.

In operating the m achine' thf'e opposed series of chucks and drills are traveled or rotated continuously. The operator stands at the side of the machine opposite the depressed portion E' of the cam E, and as the chucks reach this point and open the drilled blanks they are removed and replaced by undrilled blanks. Then as the chucks travel on they are successively lifted and thereby closed upon the blanks, holding them securely. As each chuck reaches the upper portions of the cam E the co1'respondingdrill O passes under the first shoe and drills the vfirst hole through the blank. Aft'er this iirst hole is drilled and while theV drill is separated from the blank the pin on the collar D'of such chuck contacts with the first striker U and the chuck is given a quarter-turn on its axis by means of such striker and the corresponding notchtin the ringT. Then the drill and chuck pass under the second shoe, andthe second drilling operation is performed. After passing the second shoe the drill is again thrown up by the spring and the chuck is given another quarter-turn on its axis by the striker U and notch t'. Then they pass under the third shoe S and the third hole is drilled. After passing the third shoe the drill is again thrown up and the chuck is given another quarter-turn by the striker U2 and notch t2, then passes under the fourth shoe, andthe fourth hole is drilled. Then the drill is thrown upward and the chuck, passing onto the lower part of the cam E', drops and releases the drilled button, which may be removed therefrom either by hand or by suitable apparatus, and a fresh blank is supplied to the chuck and the described operation is repeated thereon. The same operation occurs for every pair ot' drills and chucks in the ma- During each orbital travel of each drill and chuck the drill is depressed four times in drilling four-hole buttons, and the chuck is given three-fourths revolution, the lirst hole being drilled before the chuck comes into contact with the striker. In drilling two holes it is only necessary to remove the first and third shoes, so that but two holes will be drilled and at diametrically-opposite points.

I do not consider myself restricted to the particular mechanism herein shown and described, although the same has proven very efficient in operation, as it will be easy to change mechanical details while retaining the essential features and advantages of my invention.
