 ABSTRACT A multi-color marking implement designed to be used by students, artists, shipping clerks, and the like wherein the body of the implement is a tubular container comprised of a plurality of separate elongated internal liquid-tight chambers, each chamber containing a different color ink, from the others and extending from one end of the aforedescribed container body, there being a corresponding plurality of separate nibs each of which communicates with a separate ink chamber in the body to provide a different marking color for each nib.
2 Claims, 6 Drawing Figures MULTI-COLOR MARKING IMPLEMENT BACKGROUND OF THE INVENTION Multi-color marking implements, exemplified, for example, by those such as taught in U.S. Pat. No. 1,938,835 to Grzyb, dated Dec. [2, 1933; US. Pat. No. 2,554,335 to Kollsman, dated May 22, 1951; US. Pat. No. 2,585,016 to Kollsman, dated Feb. 12, 1952; and US. Pat. No. 3,079,895 to Gordon, dated Mar. 5, I963, have long been known. The marking devices shown in the aforementioned patents basically employ some method of incorporating multiple ball-point tips or conventional separate metallic pen nibs arranged in groups to provide a composite writing instrument, in which each tip or nib is supplied with a different color ink.
Additionally, the so called felt type nib marking implements, employing various single color opaque or transparent inks, such as illustrated in US. Pat. No. 3,278,976 to Ward, dated Oct. 18, I966, have also been known for some years and have come into popular use. Writing instruments using clusters of fibers to form the nib also are known.
In particular, the writing instruments employing felt nibs are advantageous to apply broader lines of ink than are possible to be formed by ball-point pens or those using conventional steel pen nibs. However, to use different colors of ink at present with felt type instruments, it is necessary to have a different pen for each color desired. The present invention obviates this necessity.
SUMMARY OF THE INVENTION It is the object of the present invention to provide a multi-color marking implement, having nibs made of felt or other suitable material, wherein one can use a single implement to write or mark with the number of colors contained therein, whereas it would otherwise require an equivalent number of separate color marking implements in order to accomplish the same result.
It is another object to provide a multiple-nibbed multi-color marking implement having nibs made of felt or other suitable material, the nibs being inserted into one end of an elongated tubular ink-retaining reservoir body having an internal construction comprising a plurality of partitions forming separate liquidtight chambers wherein the different colored inks respectively are contained. Said partition members protrude externally beyond the ink chamber section of the body to also separate the nibs from each other, thereby preventing nibto-nib contact and a resultant undesirable color contamination between the inks with the nib area.
It is a further object to feed a specific color of ink to each respective nib from a corresponding color chamber by absorptive action of the ink contacting that wick portion of the nib which is within each respective ink chamber, and a fitted cap is provided commonly to protect the plurality of nibs when the instrument is not in use and also prevent loss or deterioration of inks due to evaporation of the components thereof through unnecessarily exposed nibs, as well as to prevent said nibs from contacting clothing and other things when said implement is not in use.
A major benefit to be obtained from the present invention is that one may now do with a single multi color marking implement that which would have heretofore required a number of similar type single color marking implements. For example, with this invention a student may use as many as four different transparent color marking implements to emphasize various text materials, instead of having to use and also carry four separate markers, each with a different color ink, whereasthe student would require only one marker of the multi-color type. Further, there is a considerable facility with which the change of color of marking can be accomplished in that one merely needs to rotate the muIti-color marking implement within ones hand in order to apply a different color or blend two or more colors. Therefore, the present invention eliminates the need and necessity for handling multiple marking implements in use in order to use multiple colors.

DETAILED DESCRIPTION OF THE INVENTION Referring to FIG. 1, a multi-color marking implement 10 is shown, being generally comprised of a tubular body 12, a plurality of liquid-tight internal partition members 14 forming a series of ink chambers 16, an extended plurality of external partition members 14, a base 18, a plurality of nibs 20 with a corresponding communicating plurality of nib-wicks 22, and a detachably fitted cap 24, shown in phantom, to illustrate the nib 20 and nib-wick 22 sections more clearly.
Also referring to FIG. 1, to explain in more detail the construction of this invention, which provides a capability for multi-color marking with a single implement l0, and as heretofore indicated, said tubular body 12, has a preferred configuration generally as shown in FIG. I which contains a plurality of internal liquid-tight partition members 14 that outwardly conform in shape to the interior configuration of said tubular body I2, and extend from said base I8 interiorly to the nibretaining shoulder 19 and form a series of separate internal liquid-tight ink chambers 16. Said partition members 14, however, extend longitudinally beyond said nib-retaining shoulder 19 to form said external partition members 140, the function of which is to prevent said nibs 20 from coming into contact with each other when said ink chambers 16 are filled with different color inks, either of the opaque or transparent variety. Said different color inks communicate by absorptive action through the respectively inserted nib-wicks 22 to the corresponding nibs 20.
Said external partition members 14a, therefore, serve to separate one nib 20 from another nib 20 of different color ink, thereby preventing nib-to-nib contact which would otherwise result in undesirable color contamination between said different color inks within the nibs 20. When said multi-color marking implement it] is not in use, the nibs 20 are protected by affixing thereto said detachably fitted cap 24, which is preferably constructed of a transparent material in order to reveal the various nib colors when said cap 24 is in closed position on said body 12.
Operation of said multi-color marking implement I is accomplished simply by removing said detachably fitted cap 24, and holding said implement it] in ones hand in such a manner as to present the marking surface 26 of the desired nib 20 color to the surface to be marked. To change color, one simply need rotate said implement within ones hand to present a different color nib marking surface 26 to the surface to be marked, and proceed to apply the desired color.
The implement 10, including the detachably fitted cap 24, disclosed in FIG. 1 may be constructed of metal, or plastic, or a combination thereof, or any other suitable material. The nibs 20 disclosed therein may be constructed of felt or any other material, such as a cluster of glass or other fibers, suitable for absorptively communicating either opaque or transparent ink from the ink chamber 16 to the respective nib 20 marking surface 26.
The view seen in FIG. 2 is an enlarged cross section along the line 2--2 of FIG. 1, showing the manner by which said liquid-tight ink chambers 16, each containing a different color ink, are formed by partition members 14 within said tubular body 12 of said multi-color marking implement 10.
The view seen in FIG. 3 is an enlarged perspective of the nib section 20 shown in FIG. 1. More clearly seen, however are said external partition members 14a separating said nibs 20 one from the other, marking surfaces 26, of nibs in addition to nib-retaining shoulder 19, whereby said nibs 20 are frictionally held in place between said shoulder 19 and said external partition members 140.
In FIG. 4 there is shown an enlarged perspective view of another embodiment of nib section of the type shown in FIG. 1, wherein said nibs 20 have not only marking surfaces 26, but in addition, have marking surfaces 260 formed by a varied nib design at the outer corners thereof.
The view seen in FIG. 5 is an enlarged perspective of the nib section shown in FIG. 1, with, however, a modified design of nib-retaining shoulder 1%, wherein nibretaining shoulder 19 has been longitudinally extended to provide support for said nibs 20 between said modified shoulder 19b and said external partition members 14a. In FIG. 6 there is shown an enlarged perspective view of yet another embodiment of nib-retaining shoulder 19c design, which design provides maximum nib 20 support but includes cut away clearances in the shoulders 1% to expose corners of the nibs 20 for use.
While the invention has been described and illustrated in its several preferred embodiments, it should be understood that the invention is not to be limited to the precise details herein illustrated and described since the same may be carried out in other ways falling within the scope of the invention as illustrated and described.
