This invention relates to improvements in fountain pens.

'I'he general object of the invention is to provide a fountain pen having a novel ink container.

Another object of the invention is to provide a novel ink container for a fountain pen.

Other objects and the advantages of this lnvention will be apparent from the following description wherein:

l Fig. 1 is a side elevation of my improved fountain pen partly in section;

Fig. 2 is an -enlarged fragmentary central section through the pen showing the ink vial being positioned in the barrel;

Fig. 3 is a view similar to Fig. 2 showing the ink vial fully positioned in the barrel; and Fig. 4 is a View similar to Fig. 3 showing a modification of my invention.

Referring to the drawing by reference char-A acters I have indicated my improved fountain pen generally at IIJ. As shown the fountain pen I0 includes a barrel portion I2 having a recess I3 therein which opens through one end of thel barrel and a reduced communicating recess I4 which opens through the opposite end of the barrel. At the juncture of the recesses I3 and I4 the barrel'includes a shoulder I5 which is shown as bevelled. Adjacent its outer end the recess I3 includes a threaded section I6 and adjacent the opposite end of the barrel the barrel includes an externally threaded portion I1.

Adjacent the threads i1 a pen point i6 which may be of any desired type is secured to the barrel I2 by a plug member i9. This plug I3 includes a body portion 20 which ispositioned in the recess I4 and includes a reduced lip portion 2l and a reduced conical spur portion 22. The lip 2I extends outward from the end of the barrel I2 and has an ink groove 23 therein which is disposed below the ink aperture and slit 24 of the pen` point I3. At the end opposite to the lip 2| the plug I9 has a spur portion 22 which is shown as separately formed. and which is preferably made of metal while the body 20 may be made of hard rubber. The spur portion '22 has an end 22EL which fits within the body 20 and is held in place by a pin 22h. The spur portion 22 extends towards the threads I6 to a predetermined distance beyond the shoulder I5.

The plug I9 has a recess 26 therein which at one end opens into the groove 24 and at the opposite end extends to a point adjacent the apex of the spur portion 22. Furthermore, the spur portion 22 has a plurality of apertures 21 therein adjacent the apex thereof which open into the recess 26. Acap 28 f the usual type is shown as removably secured to the barrel I2 by engagement with the threads I1. At 29 I have indicated an ink vial which includes a hollow cylindrical body portion 36 open at one end and 5 closed at the opposite end. Adjacent the closed end the vial includes an enlarged threaded portion 3I and an enlarged head portion 32. Adjacent the open end of the vial the body 36 has an external circular groove 33 therein. l0

For closing the open end of the vial I provide a cap member 34. The cap 34 is cup-shaped and is made of rubber and fits over the open endof the body 36.v The cap 34 includes an enlarged annular flange portion 35, a portion of which is l5 positioned in the groove 33 and tightly engages the body 30. The bottom of the cap 34 includes a thickened portion 33 which extends into the body 30. 'I'he vial 29 is adapted to be lled with suitable fountain pen ink. 20

In operation a vial 29 is inserted in the barrel recess I3 with the vial cap 34 directed towards the spur 22. When the vial cap 34 engages the pointed end of the spur 22 and the vial is moved further into the barrel the pointed end of the 25 spur 22 punctures the bottom of the cap and passes through the thickened portion 36 into the interior of the vial. As the'vial is moved into the barrel the vial threads 3l engage the barrel threads I6 and then the vial is rotated to move 30 the cap flange 35 into tight engagement with the shoulder I5 of the barrel.

When vthe vial is fully positioned in the barrel the apertures 21 in the spur 22 are positioned in the vial beyond the cap so that the ink inthe 35 vial will, when the pen is used to write, flow through the apertures 21 int'o the recess 26 and then into the ink groove 24. When the ink in the vial is exhausted the vial is removed from the barrel and another vial inserted thereinto. 40 When the vial is removed the elasticity of the cap closes the puncture made by the spur 22. Thus should any ink remain in the vial it will not leak out when the vial is removed from the pen barrel. 45

' In Fig. 4 I have indicated armodied form of my invention generally at 31. As shown the barrel, plug and pen point of the device 31 are similar to those of the device I0 and like portions thereof are indicated by similarly primed refer- 50 ence numerals. In the device 31 I provide a cap member 38 for closing the open end of the barrel I2. The cap 38 includes an externally threaded portion 39 for engagement with the barrel threads I6' and an enlarged portion 4I).` The 55 cap 38 has a recess 4| therein which opens through the end thereof opposite the head portion 401, Positionedin the recess 4| I provide a pad 42 which may be made of sponge rubber and a disk 43 which is made of a suitable hard material. The pad 42 is preferably cemented to the cap at the bottom of the recess 4| and the disk 43 is preferably cemented to the pad 42.

For use in the device 31 I provide an ink vial 45 which is shown as a hollow tube 46 which may be made of metal and is closed'at one end by a hemispherical end wall 41. Adjacent its open end the tube 4B includes an enlarged peripheral ange 48. The open end of the tube 48 is closed by a cap 48 which is cup-shaped and made of rubber. The cap 49 includes an enlarged flange portion 50 which engages the tube flange 48. The bottom of the cap includes a thickened portion 5| which extends into the tube.

In operation the cap 38 is removed from the barrel and a vial 45 is positioned in the barrel recess I 3 with the vial cap 49 engaging the end of the spur 22'. The barrel cap 38 is then positioned in the end of the barrel with the curved end 41 of the vial positioned in the cap recess 4| and engaging the disk 43. Thereafter the cap 38 is rotated to engage the cap and barrel threads. Thereafter as the cap is further rotated it moves the vial further into the barrel and causes the pointed end of the spur 22 to puncture the vial cap 49 and enter the tube 46. At the same time the vial cap is being punctured the pad 42 is being compressed so that when the cap 38 is in a fully closed position the pad 42 through the disk 43 resiliently urges the vial towards the shoulder l5' thereby compressing the flange 50 of the vial cap between the shoulder I5' and the tube flange 48.

From the foregoing description it will be apparent that I have provided a novel fountain pen and vial which is simple in construction and highly efficient in use.
