ERADICATING IMPLEMENT Filed Feb. 18, 1949 INVENTOR. GREGORY SALA g mam 5y Patented Oct. 16, 1951 zsv tze UNITED S TATE S PAT E-NT OFF ICE ERADICATYING r vrennlvmn'r Gregory Sala, New York; N. Application, February 18, 1949,, Serial. NIL-77346,

This. invention relates to new anduseful improvements in. a combined writing and eradicati'ngimplement, and, more. particularly, the aim is to provide a novel and valuable duo-fountain implement wherein onefountain serves a writing point and another fountain serves an eradicating point; the present. utilityespecially in mind being the provision of an improved stenographic pen and eradicator.

According to the present invention a single article is provided, which may closely resemble an ordinary fountain pen, and which incorporates a single barrel having at one end a writing point. and at its. opposite end an eradicator point. Both fountains are inside said one barrel, but the barrelis separable into a plurality of sections ata. point, intermediate its ends to allow convenient refilling when such a refilling is required. Also, desirably, the new implement is provided with two readily removable caps, one at each end, and each for covering one of the points when the. latter is notin use. H

A featureof the invention is the subdivision of the. barrel into three readily separable sections, these being preferably threadedly connected; with the middle section a rather short or ring-like section, and which may be uncoupled from the other two sections, thereby to free the section having the eradicator point from the other two sections. In this latter connection. means are provided whereby the eradicator fountain may be readily refilled. Another feature of the invention is the'provision of a bodily removable closing valve member for the filling end. of the eradicator fountain, which valve member, in combination with a cooperating. part carried by the section having the ink fountain and further in combination with a shaped internal portion of' the ring section, restrains the fluid in the fountain last-named from accidental spill therefrom.

For further comprehension of the invention, and; of the objects and advantages thereof, reference will be had to the following description and accompanying drawings, and to the appended claims in which the various novel features of the invention are more particularly set forth.

In the accompanying drawings forming a material part of this disclosure:

Fig. 1 elevationally shows a now favored embodiment of the new implement, with both caps applied to the barrel.

Fig; 2 is a similar view, but partially broken away and partially in section, with both, the caps removed.

7 5 Claims. (Cl. 120-36) Fig. 3 i s, on a somewhat enlarged scale, a view showing the ring section in diametral section.

Fig. 4 shows the implement elevationally, with both caps removed as in Fig. 2, and, furthenwith said ring section and the section for containing the eradicator fluid both removed. Y

Fig; 5 elevationally shows merely the section for containing the eradicator fluid, with the already mentioned valve member left inplace.

Fig. 6 is an enlarged top plan view of said valve member. Fig. 7 shows the same in side elevation. Referring to the drawings-more in detail, the barrel, as a whole designated It), incorporates three threadedly connected sections IZQM and I5; the latter being the ring section. Section l2 at its tip carriesa writing point l6, which may be of the long familiar split nib type or of the rolling ball type recently coming into rather wide use. The section [4 at its tip carries a suitable eradicator point I1, which also may be of the said split nib type or of said rolling ball type.

The ring section l5 has an axial bore there through which centrally is of slightly less diameter, as indicated at (8, than its upper and lower portions, where said bore is threaded as shown at [9 and 2D. The thread I9 is for matching an external thread on a reduced lower extension 2| of the section l2, and the thread 20 is for matchingan external thread on the reduced upper extension 22 of the section 14.

The ink fountain for the point It is within a cavitation 23 in the section 12; and the fountain of eradicating fluid for the point I! is constituted by a cavitation 24 in the section 14. I

Any desired means for refilling the said ink fountain may be included; but, as herein shown, a familiar type of suction efiectuating rockerarm 25 for use in such refilling is indicated in Fig. 2.

Projected below the lower end of the extension '2! depending from the section I2, and suitably there anchored, is a substantially hemispherical projection 26.

At the upper end of the reduced extension 22 at the top of the section M, the filling opening for the-cavitation 24' is shaped to provide a valveseat for fluid-tight coaction, with a bodily r'emovable valve member 29, which latter has a central depression 30 in its disk-like top portion 3!, this. depression forseating the projection 26 when the parts are coupled as shown in Fig. 2. Then, as will be noted, said projection is received in the hollow portion [8- of. the ring section 15,

as is also the said portion 3| of the valve member 23.;

In addition to the barrel I0, the new implement is provided with a pair of separately readily removable caps 32 and 33; with, of course, the cap 32 to be temporarily removed when writing is to be done and the cap 33 to be temporarily removed when eradicating is to be done. As is conventional, the section I2 may be provided at a suitable point thereon, as at 34, with a tiny air-admission orifice. A similar orifice may be provided at a suitable point on the barrel II; but, as herein shown, the air-admission means comprises an orifice 35 through the ring section l5 opposite the recess II, and, in combination therewith, a suitably placed orifice, as indicated.

at 36, slantingly passing through the valve member 29. Thus, free use of either of the points l8 and I! cannot be hampered by trapped air in its fountain.

In order to refill the cavitation. with eradicator fluid, it is merely necessary to unscrew the section H, and lift from its seat the valve mem-,- ber 29, and them supply the said fluid as by the aid of a glass medicine dropper. Y

While I have illustrated and described the preferred embodiment of my invention, it is to be understood that I do not limit myself to the precise construction herein disclosed and the right is reserved to all changes and modifications coming within the scope of the invention as defined in the appended claims.

Having thus described my invention, what I claim as new, and desire to secure by United States Letters Patent is:
