PROCESS OF MAKING PENS.

Specification of Letters Patent. Patent d J 11 1921 Application filed April 6, 1920. Serial No. 371,582.

Be it known that I, LEWIs A. HAwKEs, a citizen of the United States, residing at Merchantville, county of Camden, and State of New Jersey, have invented a new and useful Improvement in Processes of Making Pens, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, which form a art of this specification.

y invention relates to the manufacture of pens and more particularly to those types of pens having distorted points, such as, for example, ball pointed and turned up pointed ens.

P Heretofore, in the manufacture of ball pointed and turned up pointed pens, it has been the practice to fabricate the pen in the usual manner, involving cutting out the blank or blanking, piercing or slotting, annealing, raising or shaping, hardening and tempering, grinding, slittlng to form the nibs, and finally punching the point with a suitable tool to produce the ball point or turned up point, as the case may be, each step being a separate operation.

The ball pointing, or similar operation of distortion of the point, results in great waste of material and time due to the fact that the distortion of the point, after tempering and slitting, often causes the metal to crack or clip, thus spoiling the otherwise finished pen. If. the temper is drawn out to such an extent as to avoid cracking, the pen is found to be insufficiently tempered and the deleterious effect of distortingthe separate nibs, formed by the slitting, is not reduced.

In accordance witlrmy invention, I eliminate the separate point-distorting step and distort the point after the'annealing step and coincidently with the shaping of the blank, after which the pen is hardened, temered, and slitted in the usual manner.

hus the distortion of the point is accomplished when it is soft and before the nibs are formed, with the result that the number of pens spoiled is greatly reduced and the loss, from those which are spoiled, is minimized, due to the fact that the pen has passed through relatively few operations and has had comparatively little labor expended on it. By virtue of my invention, therefore, I not only eliminate a complete operation in the process of manufacture, but

the actual waste in units is greatly reduced and the loss due to the wasted units is rendered negligible, compared to that of present methods.

I will now proceed to describe mechanlsm, suitable for carrying out the process embodying my invention, with reference to the accompanying drawings, in which Figure 1 1s a perspective view of a ball polnted pen.

Fig. 2 is a perspective view of aturned' tion, of a shaping die and punch, with the blank in position for shaping.

Fig. 7 is a cross-sectional view of the subject of Fig. 6.

Fig. 8 is a plan view of a shearing device and guides, for slitting the pen, with the upper shear removed.

Fig. 9 is a side elevation, partly in section, of the shearing device.

Fig. 10 is a cross-section of the shearing device.

The blank a, formed by stamping or cutting from a strip of metal stock, is pierced to provide the slot 6 and then annealed. After being annealed, the blank is shaped and the point distorted, to make a pen 8 having a ball point It, for example, in a raising or shapingdie. The shaping die a is cut out to the desired shape of the pen and provided with a pin d, which protrudes above its surface at a point adjacent the position of the extreme point of the pen, when in the die. Guides e, suitably mounted and made adjustable, are provided to properly'position the blank in relation to the die. A suitably driven punch f, conforming to the shape of the due and provided with a recess g opposed to in d, is adapted to press the blank a into t e. die, thus raising or shaping the blank and at the same time distorting it to provide the ball point h, through the action of pin 03, in pressing a portion of the blank,. adjacent the extreme point, into recess 9.

The raised or shaped blank is then hardened, tempered and ground. After ,the grinding operation, the nibs are formed by slitting on a line running from the point to the slot 6. The slitting operation is accomplished by placing the pen between a pair of shears j and k, the blades of which are provided with irregularities to accommodate the ball point. The lower blade j is provided with a recess Z, while the upper blade is is provided with a corresponding downward extension m. A. suitable rest n,

for the pen, is placed adjacent the end of the shears and a pair of guides 0 and p are placed on opposite sides to properly position the pen for slitting, the guide 0 being yieldingly held by means of a spring g, which permits the guide to be depressed by the upper blade during the actual slitting.

The above mechanism with obvious modification is likewise adapted for the production of a pen having a turned up point 1-.

It will be obvious that my invention is applicable to pens having any type of point involving shaping or distortion of the metal, and it Wlll be understood that I do not limit myself to the production of ball pointed or turned up pointed pens.

The apparatus described conforms to what is known in the art, except that the shaping die 0 is provided with a pin 03, the punch with a recess g, and the shears with an extension m and a recess Z. The practice of my new process however does not require Having now fully described my invention,

What I claim and desire to ters Patent is:

1. The process of making specially pointed pens which comprises shaping the blank and distorting the point in one operation and in a subsequent operation forming the nibs by slitting the pen through the thus distorted point.

2. The process of making specially pointed pens which comprises subjecting an annealed and slotted blank having a solid pointed end portion to pressure to shape the blank and impart to the point the characteristic distortion which it is designed the finished pen shall have, and subsequently forming the nibs by shearing the pen along a longitudinal center line extending through its distorted point into the front of its slot.

3. The process of making specially pointed pens which comprises cutting out the blank, slotting the blank, then annealing the blank, then simultaneously shaping theblank and distorting the point, then hardening and tempering the shaped and slotted blank, and then slitting it along a longitudinal center line extending from the front of the slot through the distorted point.

In testimony of which'invention, I have protect by Let hereunto set my hand, at Camden, N. J on this third day of A ril, 1920.
