To all whom t may concern.'

Be it known that we, PAUL F.y Dosi-ni and ANTON FEYK, citizens of the United States, and residents, respectively, of the city of New York, borough of Manhattan, in the county and State of `New York, and .Boheinia, in the county of Suffolk and State of New York, have invented a new and lmproved Pearl-Button Machine, of which the following is a full, clear, and exact de- Scription.

This invention relates to pearl button machines and has particular` reference to machines for making that type of buttons known as shank buttons, and the present invention constitutes an improvement on the invention for which Letters Patent of the United States, No. 1,182,660 were issued on our application to Holub-Dusha Co., of New York, on the 9th day of May, 1916.

Among the objects of the present invention are first to provide a means for steadying or holding the drill near its point and irrespective of its length from the drill spindle so as to prevent the bending, breaking or buckling of the drill; secondly to reduce to a minimum the likelihood of breaking or splitting of the buttons while being drilled; thirdly to provide improved facilities for easily and quickly adjusting the button holding chuck with respect to the path of movement of the series of drills around the general axis of the machine, and fourthly the provision of ej ecting means for positively and mechanically starting the button after being drilled from `the holding chuck so that the pneumatic appliances, or their equivalent, relied upon for receiving and delivering the button from the drill press will be sure to operate satisfactorily.

With the foregoing and other objects in view the invention consists in the arrangement and combination of parts hereinafter described and claimed, and while the invention is not restricted to the exact details of construction disclosed or suggested herein, still for the purpose of illustrating a practical embodiment thereof reference is had to the accompanying drawings, in which like reference characters designate the same parts in the several views, and in which- Figure 1 is a vertical central sectional yview of one of our improved button holding chucks and parts immediately associated therewith, the section being on a plane substantially radial with respect to the axis of the machine.

Fig. 2 is a front elevation of the same, but with parts in vertical section substantially in a plane tangent to the path of movement of the drills around the aXis of the entire machine.

Fig. 3 is a view somewhat similar to Fig. 1 but indicating the action of the button ejector' after the button has been drilled.

F ig. 4: is an enlarged detail view of the drill guide and button holder.

Fig. 5 is a front elevation of the saine,

parts being in section on the line 5--5 of Fig. 1.

Fig. 6 is an enlarged vertical sectional view of the drill guide and button holder.

Fig. 7 is an outside elevation of the same as it would appear looking toward the right in Fig. 6; and

Fig. 8 is a lower end or plan view of the same.

Referring now more specifically to the drawings we show at 10 a drill spindle having a chuck 11 for holding a drill 12 of any suitable caliber or length, the same usually and preferably being relatively small in diameter and of any convenient length whereby a single drill may be used for a long time before requiring to be renewed.

A button B having a shank b is shownV held in a chuck 13 having a spindle 14 of tubular form. In the drilling of a hole in the shank of a button of this type it is desirable that the hole be drilled as nearly as possible to the under or back face of the button, and it is to be noted also that the axis of the drill and hole formed thereby should coincide with the aXis of the chuck spindle. Consequently the said back face of the button lies in a plane substantially tangent to the geometric cylinder described by the drill in its revolution around the axis of the machine, it being understood that the structure of Fig. 1, for example, is but one unit of a machine involving a large number of such units arranged so that the drills all revolve in the same path around said machine aXis, as shown for instance in Letters Patent of the United States No. 1,206,518, issued at our request to Holub-Dusha Co. on the 28th day of November-1916- In view of the length and flexibility of 16 of a site corresponding to the diameter' of the drill to operate therethrough while the ,upper'end of the bore 16 is counterbored at 162L and provided with a taper 16.b where the two bores merge into each other. This taper insures the direction of the drill point down through the hole 16 when being brought into operating positionflhe lower end of the guide is notched away at 17 to a plane tangent to the side of the bore 16 for the accommodation of the rim of the button and thus .providing for the action of the drill closeV to the back face of the'button.Y f Opposite the notch 17 the lower end of the. guide is beveled off at 18 yforming a sort of' chisel point 19 at the Vlower end in the plane Yof the drill bore irland this chisel edge is undercut in arc-shape at 20 for direct contact, with the upper Vside of the shank being drilled. Theupper or crest portion ofthe undercut 2O is Y notched out at 21 to provide proper clearance for the chips. It will be understood from the foregoing description that `the chisel end 19, or its undercut 2O will bear directly upon the button shank and hold the button steady while the guide body as a whole constitutes a steadying device for theend of the drill. Hence it. will be appreciated that the drill may be. of any consideralile'length between the guide 15 and the chuck 11. The guide, serving to holdthe drill from bending or buckling7 prevents the button shank from breaking or splitting.

As above premised the plane of the button B in the operation of our machines should be substantially tangent to vthe geometric cylinder described by the drill in its revolu- V tion around'4 the axis of the machine, and

therefore it is important that the adjustability of the chuck 13 around the axis of its spindle be made as easy and convenient as possible, and when once properly adjusted with .respect to the tangent aforesaid that it be held iirmly from rotation around the axis of the spindle. To accomplish these results we providey a thimble V22 through which the lower end portion of the spindle 141 projects and against which a nut 23 bears7 the nut being threaded upon said spindle extension.

- A lug 24E is fitted in the thimble and projects into a slot 25 formed in the lower end of the chuck holder26 and so the thimble is held from rotation in the yframe of the machine but is left free for verticalmove `ment .with the chuck for inserting or removchuck holder is adapted to be lowered for loosening the chuck, by means of a cam 26a beneath which a projection 26h from the holder rides during the revolution of the chucks7 as aforesaid. Upon the loosening of the nut 23 the chuck 13 may be adjusted freely around its axis and upon the tightening ofV the nut again such adjustment is made positive and secure.

In the usual practice of button making or drilling machines the buttons after being drilled are removed or delivered from Y from the chucks so as to brin@ Vthem into position to be caught by the pneumatic deliverymeans. To this Ven d we Vprovide* an ejector27 comprisinga straight bar or Va round rod located within the spindle 14 and movablelongitudinally thereof toward and from the button. As in the previous pat-V ent above specified there is provided a V.-

shaped button seat 28 upon or within which the shank of the button is directly sup ported and which serves to center the button in one direction.. rllhe face or body portion of the button projects alongside of the button seat 28. The active end of the ejector 2'? is notched outat 29 so as to bring the extended finger portion 30 thereof in normal position at one side of the button seat 28 and just below the periphery of the face of the button as shown in Figs. 1 and 2.

At the lower end of the notch 29 is provided a shoulder 31which in abutting against the bottom of the button seat will limit the upward throw of the ejector. Any suitger 32 housedY in cam operated mechanism 4beneath the spindle Vholding devices and at the proper time the spindle chuck is lloosened to release the button and several parts ofthe mechanism are so operated relatively to one another as to cause the plunger 32 toenter the lower extension porn tion of the spindle and force the ejector A27 upward so that the removal of the butrable means may be provided to actuate the ejector 27 when the button is to be delivered` as in Fig. 3. To this end we provide a plunp tons by pneumatic or other means will be positively assured. Y We claim:
