MANUFACTURE or PENS.

To all whom it may concern.

Be it known that I, LUnovro MARCQ, ac1t1- zen of the Republic of France, residing at Boulogne-sur-Mer, Department of Pas-de-' Calais, France, temporarily residing in Gamden, county of Camden, State of New Jersey, have invented a new and usefullmprovement in the Manufacture of Pens, of which the following is afull, clear, and

exact description, reference being had to theaocompanymg drawings, whlch form a part of this specification.

My invention relates to an improved proc see for the manufacture of pens, whereby the necessary operations are greatly simplified, reducing the labor requirements, and

the cost of production, and which produces a pen of superior quality. l Heretofore in the manufacture of pens,

the pen is blanked out of the stock and the blank is subjected to the various operations a lined; p

' Fig. 1 is a plan view of a section of pen of slotting, annealing, shaping, hardening and tempering. After the tempering opera tion, which gives the necessary resiliency or spring, and before splitting the point to form the nibs, the pen is ground on a emery wheel.

The grinding of the pen is highly important, in that it causes the pen to better retain the ink when dipped and aids in causing the nibs to remain in proper relation after they are formed by splitting, and is an essential operation in the production of any high grade pen.

In the present method of manufacture, the pens are ground by hand,-one by one, or placed by an operative upon a revolving holder, which presents the pens successively to the grinding wheel and drops them into a receiver after they have been ground.

The present methods of grinding are open to a number of serious objections, primarily, the excessive labor requirements necessary to handle each pen separately and because of the loss due to waste, arising, at an advanced stage in the production, from burning and drawing the temper from the pens and from irregularity of grinding.

In accordance with my. invention, I submit the stock to a grinding operation as a preliminary step to the operations of blanking, slotting, annealing, shaping, hardening and tempering, etc., whereby I eliminate the disadvantages of the present methods and Specification of Letters Patent.

or band, is preferably groundthronghout that portion; of its surface which corresponds to that part of the finished pen from the ears to near the point. The grinding may be done with an emery wheel or'other form of grinder, or the rinding may be imitated and the ground e ect produced, by means of any form of a serrated or corrugated metal wheel, or by any other suitable means, and in referring to, grinding I mean to include any imitation thereof or effective substitute therefor.

V I will now proceed to describe a mecha 'nlsm capable of carrylng out the process 'em-" bodying my invention, with reference to the accompanying a drawing, in which- F lgure l'is a PlilII'VlGW of a section of pen stock with a double row of pen blanks outle'vation of a grinding Fig. 3 is a sectional sideviewof the grinding machine.

Fig. 4 is a top view of a finished pen. Fig. 5 is a diagrammatic view of a device for lstamping out the pen blanks from the stoc r.

Fig. 6 is a diagrammatic view of a device for slotting or piercing a pen blank.

Fig. 7 1s a dlagrammatic v1ew of a device for shaping or forming a pen.

Fig. 8 is a diagrammatic view of a device for slitting a pen to form the nibs.

The stock (1, comprising a band or ribbon of suitable metal, of sufficient width to permit a double row of pen blanks b to be stamped out, is passed between a grinding wheel 03 and an idle roll (1 and led between a pair of suitably mounted feed rolls 0, one

oft which is adapted to be driven, and which serve to draw the stock past the grinding wheel. The grinding wheel a! is carried by ashaft f, ournaled in a frame 9 and driven through a pulley it connected to any suitable source of power. The grinding wheel is preferably proportioned to grind the stock to a width corresponding substantially to that part of the stock forming the nibs of the pens and the stock is guided so that the wheel will grind it centrally, as indicated at 2'. The exact width of the ground portion is a matter of choice, but it is preferable that the ground portion shall not extend to the extreme point of the pen.

Fig. 1 shows diagrammatically the application of my invention to a section of stock a" from which a single row of'pens as b are to be stamped. Inthis case the stock is ground adjacent one of its edges corresponding toJthat portion of the pen from the ears to near the point, as shown at i.

After the stock is ground, the pen blanks are stamped out by means of a die n and a suitably operated punch 0, between which the stock is drawn by suitably driven feed rolls- 1?, 7). The blanks, as b, are then slotted as at 7s by means of a die r and a suitably driven punch s. The slotted blanks are then. annealed, by heat treating, and formed or shaped by meansofadie t and a suitably driven. punch-u. The pens are then hardened; and tempered after which they are slit to form the nibs by means of shear o, the pens being positioned by a stop to. The-completed pen j,.having the slot is and split asat m, is then finished inany customary manner.

Having now fully described my invention, what I claim andv desire. to protect by Letters Patent is 1. In the manufacture of pens, the process which comprises grinding the metal stock from which a multiplicity of pens are to be formed and subsequently formingthe pens from theground stocln.

2. In the manufacture of pens, the process which comprises. grinding. thermetal riblurgical operations adapted to convert the pen blanks into finished pens while preserv-v ing the original grinding.

4'. In the manufacture of pens, the proc ess which comprises performing the following operations in the following order: grinding the metal stockfromwhich a multiplicity of'pensare to be formechstamping out and slotting the individual pen blanks, annealing, shaping,.hardening and tempering, and slitting.

5.. Inthe manufacture of pens, the process which comprises. grinding. the metal rib bon from which the pens are to be formed along.- a Zone extending.continuously length-- wise of the ribbonand across that part of the width of the ribbon corresponding approximately to-the part of the ribbon from which the nibs of the pens are to be formed, and subsequently'performing the operations of stamping out and slotting, shaping, hardening,tempering. and slitting.

In testimony of which invention,- I have hereunto set my hand, at Camden,N. J., on this 6th day. otMarch, 1920.
