PEN NIB.

Application filed April 15, 1926. Serial No. 102,322.

This invention relates to graphic instruments and has particular reference to a an improvement in pen nibs.

rimarily the invention colnprehends an improved form of pen nib which functions to contain a large quantity of ink so as to eliminate the necessity of repeatedly dipping the same in the ink supply.

The invention furthermore contemplates an improved pen nib which is so constructed as to permit of its use at substantially any angle and in any rotated position with respect of its own axis.

The invention furthermore aims to provide a pen nib which is comparatively simple in its construction, inexpensive to manufacture, and which is highly efiicient in its purpose.

With the above recited and other objects in View, reference is had to the following specification and accompanying drawings in which there is exhibited an example or embodiment of the invention which is in no way intended as a limitation upon the scope of the appended claims as it is to be clearly understood that variations and modifications which properly fall within thescope of said claims may be resorted to when found ex edient.

n the drawings- Figure 1 is a perspective view of a pen equipped with a nib constructed in accordance with the invention, illustrating the same in use;

85 Fig. 2 is a side view thereof;

Fig. 3 is a sectional view therethrough paken approximately on the line 3-3 of ig. 4 is a perspective view of the nib blank.

Referring to the drawings by characters of reference, 10 designates a pen holder having an intermediate reduced portion 11 defining a shoulder 12 and a llllthel reduced end portion 13 defining a shoulder 14:. The pen nib 15 is of substantially cylindrical formation having an open upper end 16 ofv a diameter to snugly fit the reduced end portion 13 in abutting relation with the shoulder 14 and with its periphery flush with the periphery of the intermediate reduced portion 11. The opposite end of the nib body is provided with c-ircumferentiallyspaced V-shaped cut-away portions 17 which 66 define therebetween substantially V-shaped prongs 18 bent inwardly toward each other so that the side edges 19 of the prongs are brought into contact and the apexes 20 of the prongs disposed in close relation to serve as a writing point, thereby in effect producing a conical closed end axially slitted. The material from which the same is formed is resilientso that pressure on thepoint of the closed end against a surface will effecta slight spread or opening of the prongs. The tubular or cylindrical body of the nib immediately adjacent the conical closed end is formed with a radial feeding opening 21 which is designed upon dipping of the nib within an ink supply, to permit a quantity of ink to feed into the conical closed end.

In order to prevent possible leakage of the ink from the nib in event of laying the pen'down, a sleeve 22 is mounted on the reduced intermediate portion 11 of the pen holder for axial sliding movement, the same being limited in one direction by the engagement of one end with the shoulder 12; the opposite end is adapted to slide over the nib body to cover the opening 21 when the same is filled and ready for use. During the fillin operation, the sleeve 22 is moved upwardly to uncover the opening as will be obvious. In writing, it is apparent that the nib may be rotated on its own axis and held at various inclinations so that when sufiicient pressure is brought to bear, a separation of the prongs will permit the ink to flow for writing.

What is claimed is:

1. In a pen including a holder, a tubular nib having an open end fitted over the end of the holder and a conical lower end slitted upwardly from the apex to define resilient prongs, said nib having a radial filling opening through which ink is introduced to the interior thereof, means axially slidable relative to the nib for closing the filling opening, said closing means comprising a sleeve, and means on the holder for limiting the sliding movement of the sleeve in a direction to uncover the opening.

2. A pen including a holder having a reduced intermediate portion with respect to its upper end defining a shoulder and having a reduced lower endwith respect to the intermediate portion defining a second shoulder, a nib having a tubular body open at its upper end and of a diameter to snugly fit the lower reduced the holder with its periphery ush with ortion of.

the intermediate reduced portion, said nib having a conical ,closed lower end slitted upwardly from its apex to define resilient prongs, the body of said nib having a filling opening adjacent its. juncture with the conical lower end, a. 'sleeve arran ed for axial sliding movement on the ho der and the. tubular body portion of the nib to constitute a closure for the filling openin and an auxiliary means for connectlng tie nib 10 with the holder,'the upper end of the sleevecoacting with the upper shoulder to limit movement of the sleeve in a direction to uncover the filling opening.
