BY WW 5% United States Patent FOUNTAIN PEN Jos Carlos Millas, Tarara, Cuba Application September 3, 1954, Serial No. 454,096

2 Claims. (Cl. 120-47) The present invention relates to new and useful improvements in fountain pens and has for its primary object to provide, in a manner as hereinafter set forth, a writing instrument of this character which is adapted to be expeditiously filled by magnetically operated suction means devoid of mechanical connections of 'any kind.

Other objects of the invention are to provide a fountain pen of the aforementioned character which will be comparatively simple in construction, durable, compact, light in weight, attractive in appearance and which may be manufactured at low cost.

All of the foregoing and still further objects and advantages of the invention will become apparent from a study of the following specification, taken in connection with the accompanying drawing wherein like characters of reference designate corresponding parts throughout the several views, and wherein:

Figure 1 is a side elevational view, showing a fountain pen constructed in accordance with the present invention being filled.

Figure 2 is a view principally in vertical section through the instrument.

Figure 3 is a horizontal section, taken substantially on the line 3-3 of Figure 2.

Figure 4 is a view in horizontal section, taken substantially on the line 4--4 of Figure 2.

Referring now to the drawing in detail, it will be seen that the embodiment of the invention which has been illustrated comprises an ink barrel of suitable dimensions and material which is designated generally by reference character 5. One end of the barrel 5 is closed, as at 6. Fixed in the closed end portion of the barrel 5 is a disk 7. The disk 7 and the closed end portion 6 of the barrel 5 are provided with air vents 8. Mounted in the other end portion of the barrel 5 is a suitable pen point 9.

Of course, the barrel 5 is for the reception of ink, as at 20. Mounted for reciprocation in the barrel 5 is a piston armature 10. In the embodiment which has been shown, the piston armature 10 includes a cylindrical body 11 of steel or other suitable magnetic material which is "ice enclosed in a covering 12 of suitable non-magnetic material such as glass or a plastic.

An elongated cap 13 of suitable material is removably mounted on the barrel 5 for enclosing and protecting the pen point 9. The cap 13 includes a suitable clip 14. Mounted in the closed end portion of the cap 13 is a permanent magnet 15. A plastic disk 16 is fixed in the cap 13 for retaining the magnet 15 in position. Below the disk 16, the cap 13 is provided with an air vent 17.

It is thought that the manner in which the pen is filled will be readily apparent from a consideration of the foregoing. Briefly, the barrel 5 is held in the position shown in Figure 1 of the drawing and the lower end portion thereof is immersed in a bottle of ink, as at 18. When the barrel 5 is held in this position the remaining ink therein and the piston 10 will, of course, gravitate to the lower end portion of said barrel. The cap 13, which has previously been removed, is then placed alongside the barrel 5 with the permanent magnet 15 adjacent the piston armature 10. The cap 13 is then slid upwardly along the barrel 5 for magnetically elevating the piston armature 10 thereby drawing ink into the barrel. Of course, the vents 8 prevent the piston 10 from being air bound.

It is believed that the many advantages of a fountain pen constructed in accordance with the present invention will be readily understood and although a preferred embodiment of the device is as illustrated and described, it is to be understood that changes in the details of construction may be resorted to which will fall within the scope of the invention as claimed.

What is claimed as new is as follows:

1. A fountain pen comprising, in combination, an ink barrel, a magnetic piston armature operable in the barrel for filling the same, a cap removably mounted on one end portion of the barrel, and a magnet in the cap, said cap being manipulable alongside the exterior surface of the barrel for bringing the magnet close enough to the magnetic piston armature to attract and actuate same.

2. A fountain pen comprising, in combination, an ink barrel, said barrel including a closed end having air vents therein, a magnetic piston armature slidable in the barrel, a cap removably mounted on the barrel for enclosing the point, and a permanent magnet mounted in the cap, said cap being manipulable alongside the exterior surface of the barrel for bringing the magnet close enough to the magnetic piston armature to attract and actuate same for filling the barrel.
