Application April 25, 1945, Serial No. 590,155

2 Claims.

This present invention relates to an ink eraser attached to a fountain pen.

The primary object of the invention is the provision of an ink eradicator that is as readily available as the fountain pen with which it is combined, that will not spill any fluid, but apply the same in moderation and in the amount desired, that will carry the container holding the eradicator fluid in a position in which the fluid is readily applied or in another position in which no fluid can escape and do any harm.

It is a further object of the invention to proyide an ink eradicator of the type described that is of simple, sturdy and inexpensive construction.

With these objects and other objects that may appear as the description proceeds, in view, this invention consists in certain novel features of construction, combination and arrangement of parts to be hereinafter more fully described and claimed.

The specific objects of the invention will appear more clearly from the following description read in connection with the accompanying drawings, in which:

Fig. 1 is a side elevation of the body of a fountain pen and a longitudinal diametral section through the cap thereof equipped with an embodiment of my invention;

Fig. 2 is an enlarged longitudinal, diametral section of the upper or outer end of the cap equipped with an embodiment of my invention and on line 22 of Fig. 1;

Fig. 3 is a top plan view of the cap equipped with an embodiment of my invention after the removal of the cover;

Fig. 4 is a detail side view of the sponge and tube carrying the same both forming part of the embodiment of my invention.

In the drawings in which like reference characters indicate like or similar parts, numeral 2 indicates in general a conventional fountain pen body including a pen p and carryin a cap 3 which includes a clip and encloses only a relatively small upper portion of the pen body and therefore has a hollow portion there above which is utilized in my invention. The substantially hemi-spherical end portion 4 of the cap is detachable from the remainder and provided on its inner side with threads 5. These are threaded on exterior threads formed on the outer side of a cylindrical flange 6 coaxial with the semi-spherical cover 4 and the remaining portion of the cap from which this flange extends and to which it is connected by an inwardl extending flange 1 which defines an exterior shoulder of a width equal to the thickness of the cover wall.

To the inner side of the cylindrical flange is secured the outer side of the cylindrical end portion of a well or cup 8 which is closed at the lower hemi-spherical end and has the general shape of a conventional fountain pen cap. This cup is filled with ink eradictor fluid 9 into which extends a tube 10 open at the lower end; the tube also extends upward through and is secured to the central portion of an end wall II which is fitted in a fluid-tight manner in the upper end portion of the cup. This end wall is preferably fixed to the inside of the cup and supports a sponge rubber l2 or other spongy substance into which the upper open end of the tube extends. The upper surface of the end wall is not flush with but slightly below or inward the open end sur face of the cup so that the upper end of the cup forms a flange [3 which surrounds and clamps the sponge rubber. The latter may take various forms, cylindrical, cubical, etc. The preferred form resembles the shape of a pyramid, being distinguished therefrom by a ridge 2; taking the place of the apex of the pyramid.

In order to replenish the ink eradicator fluid a threaded hole is provided in the end wall closing the upper end of the cup. A threaded filler plug [4 notched in the upper end for the insertion of a screw driver is screwed into the hole and removed therefrom to fill the cup with ink eradicator fluid.

In order to eradicate ink the cover 4 is removed and the whole pen inverted with the result that the sponge is dampened by a small quantity of the fluid flowing down in the tube. The sponge is then applied to the ink spot or line to be eradicated. Should the eradicator fluid in the sponge prove insufficient, the latter may again be moistened by successively inverting the pen.

Various modifications and changes are contemplated and may obviously be resorted to, without departing from the spirit or scope of the invention as hereinafter defined by the appended claims.

What I claim as my invention and desire to secure by Letters Patent is:

1. In an applicator for ink eradicator, an ink eradicator fluid holding well adapted to be mounted in a detachable fountain pen cap, conduit means, open at both ends, having one end immersed in a fluid contained in the well, said well having an open end provided with a closure through which the opposite end of the conduit w a 3 I 4 V 7 means extends, a sponge secured to the closure UNITED STATES PATENTS V and into which the outer end of the conduit ber Nam means p and means f e p y g a fining 2po3 Stacy 3% 19o7 the well- 1,153,807 MacPherson Sept. 14, 1915 2.
