Specification of Letters Patent. Patented J line 29, 1920.
Application filed April 12, 1919. Serial No. 289,730.
will be fully illustrated in the drawing, de-' scribed in the specification and pointed out in the claim at the end thereof.
In the accompanying drawing,
Figure 1 is a longitudinal cross section through the barrel of a fountain pen'with my pen attached thereto.
Fig. 2 is a plan view of the metal blank from which the pen is formed.
Fig. 3 is a side elevation of the pen.
Fig. 4 is an end elevation of the pen.
Fig. 5 is a perspective view of the pen.
Fig. 6 is a perspective view of the ink feeding tube.
In the several figures of the drawing, like reference numerals indicate like parts.
The pen indicated by reference numeral 1 is suitably held in place in the penholder 2 and surrounds the ink feeding tube 3. The penholder 2, in turn, is fastened to the barrel 4 and has the ink sack 5 attached thereto. The ink sack 5 is closed at one end and is fastened to the penholder 2 with its open end through which the ink is adapted to flow on its way to the ink feeding tube 3 and the pen 1.
The barrel 4 of the penholder is slotted at 6 to admit a suitable implement by means of which the ink sack 5 may be compressed to expel the air therefrom. When the sack expands thereafter it will suck up ink from any source of supply in which the tip may be immersed. In order to compress practically the full length of the sack a spring member 7 is fastened to the barrel 4. This spring member extends along a portion of the inner periphery of the barrel at the point where the slot 6 is located and closes the slot. On the insertion of an implement into the slot 6 the spring member 7 will be forced against the sack 5 and compress the sack the full length of the spring member 7 a expelling the air and ink as above point e out.
The pen 1 is bent up from the blank 8, which blank is preferably made of sheet metal and has a series of three triangular points 9 formed on one side thereof. The
blank 8 is rolled into a tube and the ends.
of the triangular points 9 are brought together at their extreme ends to form a conical end on the tube as shown in Figs. 3, 4'
and 5.
Each of the triangular points 9 has a small recess 10 cut into each of its sides near the pointed end thereof.
These recesses form small openings 10 in the conical end of the pen after it has been formed up. Along these openings 10 and along the slots formed between the triangular points the ink flows from the feeding tube 3 to the end of the pen point 1.
The feeding tube 3 may be provided with one single opening in the end thereof as shown in Fig. 1 or it may have three openings as shown in Fig. 6. In the latter case the end of the feeding tube is formed in the shape of a triangular pyramid. The openings leading into the central duct of the tube are provided in each of the edges of the pyramids, as shown in Fig. 6.
The result obtained by constructing the pen in the manner above described, is as follows:
In writing with this pen the conical end of the pen causes the ink to be applied in lines of even thickness no matter what pressure is applied to the pen. This result can with a sharpened pencil, but'while the pencil will wear and soon have a blunt end and write heavier, the pen will not wear at its point and will always write in the same even thickness.
The fact that the pen comprises three pen points, each being separated from the other by a narrow slot, insures a constant and even flow of ink from the feeding tube to the point of the pen. The narrow slots between the pen points increase the capillary attraction of the pen so that the ink from the feeding tube is quickly taken up by the pen and fed toward the pen point during writing.
The triangular pyramid shaped end of the feeding tube is so adjusted in the pen that the edges thereof are placed adjacent I claim:
A pen comprising a cylindrical body having a conical end formed thereon, said conical end being divided into a series of pen points, said pen points having notches cut into the-sides thereof adjacent to one another to form openings in the conical endof:
the pen, and a feeding tube projecting into the conical end of said pen, said feeding tube being cone shaped and having openings 10 in the side thereof adjacent to the openings in the pen.
In testimony whereof I affix my signature.
HALFORD B. WARDIN.
