CONE-PUNCTURNG MACHIN. i

Application led December and burs or rough spots were thereby formed l upon the exteriorof the cone so that .the

yarn did not unwind cleanly and frequently broke so that there was a great waste. It is the obJect of my invention to provide a puncturing mechanism by the use of which the'eones will be punctured inwardly from their eXteriors and the outer surface'of the cone will be left just as smoothA as before it was puncturcd. This object I attain in the use of such an apparatus as is illustrated in the accompanying drawing, and the, in-` vention consists in certain novel features which will be hereinafter first fully described and then particularly 1pointed out in the claims. y

VIn the drawing Figure 1 is an elevation of amachine em-v bodying my invention, and

Fig. 2 is an enlarged longitudinal section of the puncturing devices showing a cone in position to be punctured. Y

In the. drawinggthe-reference numeral 1 indicates a bench or rigid supporting frame upon which is secured a post or pedestal 2 having a horizontally disposed cylinderl 3 mounted upon its upper end. The reference numeral el indicates a tank for compressed air or other motive fluid, such as steam, which is kept supplied with the fluid under pressure in any convenient manner, as by connection with a steam boiler or with an air compressor. From the tank or reservoir il, a pipe 5 extends along the table or supporting frame 1 and leads into a controlling valve 6 of any known or approved form whereby the flow of the fluid may be conf trolled. From the valve 6, pipes 7 and 8 eX- tend to the cylinder 3 and communicate with the interior thereof through the. heads or ends of the same, as will be readily understood. `Within the cylinder is mounted a reciprocating piston 9, the piston rod 10 of which extends through a packing box 11 on one end of the cylinder and is slidably supported and guided in a bearing 12 which is erected upon the frame or table 1. The free end of the piston rod beyond the bearing 12 Serial No. 756,591).

PATENT OFFICE. i i

' is equipped with a head 13 which may be A a collar having an annular groove 14 in its l 'out-er circumference andis disposed within a hub 15 which is secured upon the reduced end 16 of the bearing 12 by set screws 17 in* serted radially through one end of the hub @land bearing against the saidreduced eX- tension, as clearly shown in Fig. 2. AThe hub 15 is constructed with longitudinal slots 18 between its ends and at intervalsaround its entire circumference. At ythe sides of these slots are outwardly projecting lugs or ridges 19 having transverse notches formed` in their outer edges to receive a stout rodY 2O which encircles the entire hub and is secured in the said notches by/clamping bolts 21. This rod 2O constitutes a fulcrum for the puncturing arms 22L which are provided at their 'inner or pivoted endswith inwardly projecting fingers 23 passing through the slots 18l and engaging in the annular groove 111 of the head 13. The outery free working the paper cone 25 which is supported' upon a. mandrel 26 carried bythe hub 15'. As

lshown most clearly in Fig. 2, the outer or free end of the hub 15 is constructed with 1an annular shoulder 27 and is tapered, as at 28, beyond said shoulder so that the vconical mandrel 26 may fit closely about the tapered end of the hub and abut the shoulder 27, being secured tothe hub by set screws 29 inserted through its end portion into the hub, as clearly shown. The mandrel is preferably an integral metal casting havin@ teeth 30 formed upon its exterior, the said teeth projecting toward the hub so that the cone may be very readily slipped over the outer end of the mandrel and held thereon while being punctured.l At intervals around theV mandrel longitudinal slots 31 are formed through the wall of the same, and these slots are so arranged as to be in alinement with the puncturing spurs or points 211 of the respective puncturing arms.

The use of the device will, it is thought, be readily understood.` It is evident that the flow of compressed air, steam or other motive fluid may be directed into either end of the cylinder 3 byr adjusting the valve 6 and the operation ofthe machine is thus easilv controlled by the workman. Assuming the parts to be in the position shown in the drawing, the valve 6 is set so that the mothe cylinder and drive the pistonv toward the right-hand end of the cylinder in Fig. l,

this direction of movement being indicated by the arrow in Fig. 2. The head 13 'upon the piston rod will thus be caused to move toward the reduced extension 16 and will cause the fingers 23 to swing in the same direction, the lever arms being, consequently, rocked about the fulcrum rod 2O so that the spurs 2li- Will be forced inwardly through the shell or wall of the cone 25. TWhen the cone has been punctured, the valve 6 is reversed or set so that the motive fluid may exhaust from the lefthand end of the cylinder and will be admitted through the righthand end thereof so that the piston will be given a reverse movement and the parts returned to the positions illustrated. The cone may then be easily removed and a new cone fitted upon the mandrel to be punctured. It will be readily noted that with my apparatus the cone is lirmlysupported while being punctured and the holes formed by the puncturing spurs will be clean and sharply defined and the slight bur which is produced by the puncturing act will be formed upon the inner surface of the cone where it 'cannotaffect the winding or the unwinding of the yarn. lVhile I have shown and described my device as being operated by fluid pressure, it will be understood that it may be operated mechanically or by hand without involving any departure from the spirit or scope of the invention as the same is vdefined in the following n claims.

Having thus described the invention, claim -l. Means for puncturing cones comprising a slotted tapered mandrel to t within and support the cone, puncturing arms mounted adjacent one end of the mandrel to extend longitudinally Vover the mandrel and a cone supported thereon, and means for actuating said arms whereby portions of the arms will pass inwardly through the wall of the cone toward the Ymandrel to puncture the cone.

2. Means for puncturing cones comprising` a Vtapered mandrel to t within and support a cone and having slots formed through its wall atintervals around its circumference, rocking puncturing arms mounted adjacent one end of the mandrel and disposed about the same and provided on their Vinner edges with puncturing points presented to the slots in the mandrel andato a cone supported on the mandrel,` and means for rocking said arms whereby to cause the puncturing points to pass inwardly through the wallV of the cone into the slots in the mandrel.

3. Means for puncturing cones compris lng aA hub provided with longitudinal slots Yin its circumferential extent, a tapered man` drel secured to the end of the hub and projecting therefrom in axial alinement,

wardly through the slots in the hub, a head housed within the hub and engaged 'with the free ends of said fingers, and means for reciprocating said head whereby to rock the puncturing arms toward and from the man drel.

In testimonyV whereof I affix my signature. Y
