STICK PIN AND METHOD OF MAKING THE SAME.

Application filed. November 13, 1924. Serial No. 749,671.

My invention relates to new and useful improvements in stickpins and to the method of making the same, and has for an object to produce an ornamental stickpin, the head Of which is stamped from a blank of relatively soft metal, such as aluminum.

I have found that by forming the head of aluminum the same will flow easily when swedged and tightly grasp the pin or prong, as will be hereinafter more fully described.

Furthermore, the head when formed of this metal presents a polished or silvery appearance, will not tarnish, and is soft enough to take a clean and clear cut ornamental im- 1 pression from the die.

Another object of the invention is to provide the rear of the head with a hub in which there is a slot extending nearly across the same and into which will be fed the pin or prong, after which the head will be subjected to a punch which will swedge the metal about the slot inwardly and downwardly to thereby tjghtly anchor the pin or prong within the heat The invention in its broadest aspects is somewhat similar to the invention shown in the application filed by me in the United States Patent- Ofiice on October 23, 1924, bearing Serial No. 745,329. In that disclosure,

30 however, a button head is shown formed from a blank of soft metal, the blank being out from a rod of wire, and the hub shown is a hollow one. In the present instance, however, the metal head is provided with a hub in which there is formed a slot for the reception of the pin or prong.

Another object of the present invention is to form a stickpin, the head of which is formed from a soft metal blank and one of the dies to which this blank is subjected is engraved or stamped with some ornamental configuration; also, the hub thereof is slotted for the reception of the pin or prong. These heads are then subjected to a second set of dies and before the plunger descends the pin or prong is fed to the slot in the hub and the hub then swedged to form the complete article.

Still another object of the invention is to provide a stickpin, the head of which, and even theprong are made of relatively soft metal, the pin swedged tightly within the head and the entire operations being performed at amaximum rate of speed.

With these and other objects in view, the

prong being subjected to the swedging opera-,

tion.

Fig. 2 is a view of the punch for swedging the head and anchoring the pin or prong in position, taken at right angles to Fig. 1.

Fig. 8 is a bottom plan view of the punch.,

Fig. 4 is a topplan view of the die. Fig. 5 is a sectionalview thereof.

Fig. 6 is a bottom plan of the pinhead showing the slot for orprong. f

Fig. 7 is a sideelevation of the same.

Fig. 8 is a. detailed view of the blank from which the head is made.

lig. 9 is a rear view of the completed pin, an

Fig. 10 is a side elevation of the completed pin, the prong being shown in section.

At the outset it might be stated that the design as shown for the head of this pin is the subject of an application for a design patent filed by Leonard R. Carley, October 22, 1924, bearing Serial No. D 11,139, but it is to be understood that the head of the stickpin may have any design formed thereon, as desired.

Referring now to the several figures, there is shown in Fig. 1 a die 1 having cut in its upper face 2 a design of a dogs head, as shown by the numeral 3. A plunger or punch 4 is the reception of thepin shown having cut therein the sloping side wall 5' and the short transverse passage 6 through which the pin or prong 7 may pass.

Referring now specifically to the pinhead there is shown in Fig. 8 a blank of soft metal which is subjected to a set of dies not shown) to press the blank into the pinhead 8, as shown in Fig. 7, the pin head being provided with the hub 9, the side walls of which are vertical,

while within the hub is pressedthe slot 10.

The first dies for forming this head (not shown) will have an ornamental configuration cut in one of theirfaces tostamp the desired design on the'fa'ce of thebutton head, and the head inthe form shown in Fig. 7 will then be subjected to the punch and die as shown in Fig. 1. At the same time, the prong 7 which is formed of a wire will becut and shaped and'fed to the slot- 10, after'which the plunger 4: will'descend to. swedge the metal about the slot around the one end of the I prong and thus anchor the same rigidly in position. j comparing Fig. 7 with Fig. 10 it will'be seen that the entire character or shape of the hub has been changed, as the swedging action due to the sloping walls cut in the plunger 4:, force the side walls of the hub inwardly and downwardly to completely fill up the slot and tightly anchor the prong in posltion. It will be understood that the configuration cut in the die 1 will be the same as cut in the first die (not shown) which forms the pin head from the blank, asshown in Fig. 7.

The making of the pin in its entirety starting with the blank, and then with the shaped in head also, the ronc bein cut and then fed to the plunger and dieshown in Fig. 1, is

all performed in one automatic header and these pins may be turned out at the rate of between one'hundred and one hundred'fifty aminute. a

' I am aware that it is old to clamp a prong or wire by bending over metal arms, but in the present instance, it will be seen that l have formed pin head having a hub and slot lnto which is passed a pin or prong and t-he entire hub being swedged has changed its character cut impression andalso flows easily, making the entire cost a very low one and at the same time forminga-Very pretty stick pin.

Many slight changesmightbe made without departing from the spirit and scope of the invention.

Having thus described my invention, what I claim as new and desire to secure by Letters .latent is:

A pln comprising a head member of soft metal having a cylindrical. hub atthe side thereof, provided with a slot at the outer end, said slot being disposed diametrically of the hub and leading in from one side thereof and terminating short of the diametrically oppositeside'thereof and a pinhaving an end inserted in the slot, the material ofthe' hub over that portion of the pin which is located in the b 1 same upon the hub.

In testimony whereof I afliX my signature.
