SAFETY-PIN MACHINE.

SPECIFICATION forming par/t of Letters Patent No. 713,728, dated November 18, 1902.

Application led April 29, 1901. Renewed March 20, 1902. Serial No. 99,034. (N model-3 To t/Z whom zit may concern,.-

Be it known that I, PETER E. WIBERG, a citizen of the United States, and a resident of Bloomfield, in the county of Essex and State OfNew Jersey, have invented certain new and useful Improvements in Safety-Pin Machines, of which the following is a specification.

My invention has reference to safety-pin machines, and relates more particularly to ro mechanism for coiling the wire and for making and attaching the coil-guard to the pin during the process of the manufacture of the latter. Heretofore the guard which surrounds the coil at the lower end of the pin has been i5 put on by hand after the pin has been manufactured and clenched in position by means of a foot-press.

My invention contemplates means whereby the guard can be stamped out automatically zo and put on the pin while the latter is being coiled, all in one continuous operation.

To this end the invention consists in the hereinafter-described means, which may be utilized in connection with the process disclosed in a sister application executed by me on the 5th day ofApril, 1901, Serial No. 57,922.

In order to explain myinvention more readily, I have embodied it in the machine shown in the accompanying drawings, in which the 3o invention is convenientlyillustrated5 but variations and changes may of course be made within the scope of the claims.

Figs. 4, 5, 6, and 7 are detail views showing the pin at its different stages of development and the relative positions and functions of the members of the 4o ceiling-spindle. Fig. 8 is a side view of the cam which operates the spindle B and adjacent means. Fig. 9 is a side view of one of the levers operating the members of the spindle B.

Similar letters of reference indicate corresponding parts in the different views.

I shall describe a safety-pin machine embodying my invention and afterward point ont the novel features in the claims.

Machines for making safety-pins are usually constructed so as to receive a strand of wire and to cut it into suitable lengths for different sizes of pins, after which the lengths of wire are carried, by means of two helically-screw-cut rods acting as conveyers, to the means for putting on the cap at the top, making the coil, &c., the points being put on by a set of files acting on the pins while in transit. My machine may be constructed to act on pins which have or have not had the cap at the top put on or which have not yet been pointed, such matters being immaterial so far as this invention is concerned; but the machine will preferably be constructed as shown in the drawings.

-A represents the ends of the helical screws which feed the pins ct',shown in thisinstance as being merely pointed without having any caps put on, and d10 is a rack for keeping the pins on the screws A and to prevent their being thrown off by the rotation of the said screws. As the pins reach the ends of the screws A they drop on the anvil m and have their upper ends bent by the hammer lm2. The hammer m2 is pivoted in the extension c2 of the framework C and is operated by means of the cam d', mounted on the main shaft D. As the pins drop in position on the anvil m they are also supported by the central movable member o of the spindle B. The spindle B is mounted in the bearings b5, adapted to slide in the groove c of the framework C, and carries four members b', h2, b3, and b4. This spindle partakes of three motions-viz., a rotating motion, a reciprocating or longitudinal motion, and a transverse sliding motion in the bearings b5. Besides, the four members b', b2, b3, and b4 each have a separate motion independent of but harmonious with the movements of the spindle. The rotating motion of the spindle B is imparted by means of the pinion h6 being rotated by the rack e, carried by the forked lever E, having the roll c2 coperating with the cam e3 on the main shaft D. The lever E is provided with a bolt e4, which slides in the slot e5 of the lever c6, pivoted at e7 to the framework and projecting into the bearings b5, whereby the said bearings carrying the spin- IOO die are given a transverse motion back and forth. As the spindle B rotates it moves forward and backward by reason of the threaded portion' 197 cooperating with the threaded portion 198 in the bearings b5.

The cam e3 is constructed with a portion elo, which operates on the roller e2 so as to cause no movement of the spindle B while the roller e2 is traveling over the said portion elo. Of course when the roller e2 is on the return movement the spindle slides back in the bearings 195 and rotates in the opposite direction, so that it is moved back to its original position with each complete revolution of the cam e3.

Upon the extension c5 of the framework C are pivoted four levers f', f2, f3, andj'4, each provided With a friction-rollf5 at one end` engaging, respectively, with the cams f6, f7, f8, andfi, conveniently mounted on the shaft D. These levers and cams operate the four members of the spindle B, causing the said members to protrude from the latter at the proper time to perform their various functions. The central member Z9' is in the form of a stem extending through the center of the spindle B and terminating in a rounded portion b9, eX- tendinginto the slot]C10 of the leverfl, in which slot the said rounded portion is free to move transversely, so as to conform itself to the transversemovementofthespindleB. Theleverf terminates in a forked portion, forming a guidewayf, in which guideway the sq'uare piecef12 slides. The square piece]C12 surrounds the spindle B and by its cooperation -With the'guidef11 compensates for the sliding movement of the said spindle. The member b3 consists of a pivoted portion Z912, terminating at one end intwo arms Z920 and at the other end in the portion Z913, attached to the stem Z914, provided with a button Z911, extending into the circular groove fle in the square piecef12,which latter having a longitudinal sliding movement on the spindle B when actuated by the cam and lever causes the longitudinal movement of the stem Z914. The circular groove f13 is provided in order that the button may slide in same, and thus adapt itself to the rotation ofthe spindle B.

The coiling member b2 is in the form of a stem and extends longitudinally through the slot blo and is operated in a manner similar to that described in connection with the member b3.

The guiding member 194 consists of a guide portion Z915 and a stem Z916, operated in the same manner as the members b3 and b2.

The coil-guard G is made from a strip of metal fed in any well-known or suitable manner to the portion Iq,where it is acted upon by the blanking-die g2, operated by the lever g3, cooperating with the cam g4, after which the blank is operated upon by the forming-die g5, operated by the levers g6 and g7 and the cam g8.

The guard Gr, after it has been formed, is received by the conveyer H, constructed,

preferably, with two arms h', of springy maA terial, meeting at the top and forming the recess h2, a supporting portion for the guard being formed by the projection h3 on one of the arms h. The conveyer H has a pin 71.25, traveling in the curved slot h4 of the framework and is further pivoted at h5 to the arm h6, which latter has a pin-and-slot connection 71.7 with the lever hs, pivoted at h9 in the framework C and attached at its other end k12 to thev operating-lever 79.10, cooperating with the cam hu on the shaft D. The curved slot h4 is so constructed as to bring the conveyer H alternately in alinement with the die mechanism and the point of the pin, as shown in Fig. 2. The lever hf is also provided with a contacting portion hw, havinga sharp edge adapted to engage with a similar contacting portion 7L on the rock-arm h, pivoted at 7x16 and having a pin h at its upper end working in the slot 7tlg of the tongs 7tlg, pivoted at h2o to the framework and provided with the ljaws b21, adapted to grasp the pin for the purpose hereinafter explained.

I is a punch mounted on the rock-arm t", pivoted in the framework and operated by the roller 712, cooperating with thecam t3.

The operation is as follows: The pin, being delivered by the helical screws A, is dropped upon the anvil m, where it is operated upon by the hammer m2, thereby both bending and holding the pin; but if the head or cap has already been put on, as shown in Figs. 4f, 5, 6, and 7, means are provided for grasping and holdingthepinonlywithoutbendingthe same. At this moment the member Z9 will protrude from the spindle B and support the pin atthe pointwhereitis to be coiled. The coilingmember 192 now protrudes, and the spindle B commencestorotate,thuscoilingthepin. Simultaneously with this the spindle also moves transversely, so as to compensate for the taking in of the wire as it is coiled, and moves forward a distance equal to the thickness of the material-that is, the wire forming the pin-so as .to enable the strand to be properly coiled. Vhen the wire has been partially coiled, as shown in Fig. 2, the Various movements of the spindle cease and it remains in the place indicated, owing to the construction of the cam elo, as hereinbefore explained. At this moment the point of the pin is grasped by the tongs h1, so as to insure perfect alinement, while the conveyer H brings the guard G, previously taken from the dies, and slides it up on the pin, the said guard being provided with a hole for that purpose. When the said guard has been brought up a proper distance, the member 193 protrudes from the spindle B and with its two arms Z920 lifts the guard from the conveyer H, the said conveyer returning quickly, and the spindle B again rotates and moves transversely, thereby continuing the coiling operation until it is iinished, the two arms Z920 of the member b3 meanwhile pressing the guard on the coil until it has reached its proper position. Just prior IOO IIO

to this the central member b and the ceiling member b2 are drawn in, the guiding member b4 having just previous to this come out, thus steadying the pin. The central member b noW shoots out again, While the punch I, being new opposite te the central member en account et the transverse movement of the spindle, is operated'at the same moment7 thus clenching the guard in position on the pin. All the members are new drawn in and the pin drops into a suitable receptacle on the machine, after which the spindle B returns toits original position and the operation is repeated.

In addition te ceiling the pin and putting on the guard the means herein described Will close the pin, as shown in Fig. 7, if the said pin has been provided with a cap prior tothe operation described herein taking place.

It Will of course be understood that any suitable form of die may be used. The dies shown in the drawings are merely conventional representations, and, further, that the guards might be stamped out independently of the conveying' means and fed to the pins or te the conveying means in some other suitable manner.
