PEN

Original Filed Jan. 7, l957 INVENTOR 4 L/ol a 7: Jenkins a BY UL, My

ATTORNEY United States Patent and this application Jan. 19, 1961, Ser. No. 83,685 2 Claims. (Cl. 120--42.16)

This invention relates to a writing pen, and, more particularly, to a pen having means for containing two or more compositions in separated locations, and means for feeding the compositions to a common writing point and thence to a writing surface.

The pen of this invention is particularly suited for carrying out the methods set forth in my cop ending application Serial No. 632,898, filed January 7, 1957, entitled Luminous Writing, now U.S. Patent No. 2,977,- 320, issued March 28, 1961, of which this application is a division. In the aforementioned patent are described certain compositions which are capable, when mixed together, of reacting to produce cold or chemiluminescent light. The pen of this invention provides separated reservoirs for containing such compositions as well as means for feeding the compositions to a common location Where they are mixed with each other to form. a chemiluminescent light-producing substance, which substance is then immediately transferable to a Writing surface to form glowing writing characters or outlines.

One object oi this invention, therefore, is to provide a writing device for containing and feeding two or more separated compositions to a common location, which common location in the illustrated embodiment is a writing ball of the type utilized in ball-point pens.

Another object of the invention is to provide, in a ball-point type pen, a plurality of separated reservoirs which communicate simultaneously with a common ball.

Another object of the invention is to provide a novel writing instrument which includes a plurality of chambers or reservoirs for separately maintaining two or more difierent compositions as well as means whereby the compositions may be fed unmixed to a common mixing and writing element.

Other objects will be apparent from the remainder of the specification and drawing.

In the drawings which form a part of this application:

FIGURE 1 is an elevational view, partly broken away, of the writing device with its associated parts;

FIGURE 2 is a sectional view taken on line 2-2 of FIGURE 1; and

FIGURE 3 is a sectional view taken on line 3-3 of FIGURE 1.

Referring to the drawings, a hollow cylindrical pen barrel 1 is provided at its upper end with screw threads 2 to which a screw threaded cap 3 is attached. A conical tip 4 is provided at the lower end of the pen barrel 1 with a cylindrical threaded extension 5 which is attached to the threaded end 6 of pen barrel 1. The conical tip has a ball point 7 seated in aperture 8, Ball point 7 also functions as a ball check for permitting free flow of fluid when the ball is rolled upon contact with a writing surface and which, upon cessation of the rolling pressure, shuts oil the flow of writing fluid. As shown in all of the figures, pen barrel 1 has a diaphragm or separator 9 vertically disposed on a diameter of the cylindrical barrel 3,094,105 Patented June 18, 1963 ice 1 and dividing the interior of the barrel into two chambers. The separator 9 extends into and divides the conical screw tip 4 substantially down to the ball point 7. A suitable seal 10 is disposed between the end of the separator 9 and the ball point 7, and a flat disc type seal 11 is provided between the screw cap 3 and the

reservoirs

12 and 13 formed in the pen barrel by separator 9.

The following serves to describe one method of utilizing the invention as a writing device.

Reservoirs

12 and 13 are filled separately by unscrewing the screw cap 3 and adding suitable solutions of the reactive components set forth in the aforementioned co-pending application into the respective reservoirs, one solution to each reservoir, with a medicine dropper or any other suitable filling device. The screw cap is replaced and the seal 11 contained therein seals off the reesrvoirs. Writing is accomplished by rolling the ball point on a surface. This causes a flow of the solutions and a mixing thereof on the ball point 7 at aperture 8 immediately after which the mixture is transferred from the ball point 7 onto the surface to form writing characters or outlines, with a chemical reaction occurring to render the writing characters visible by generation of chemiluminescent light.

To provide a description of a complete specific embodiment of the invention, it may be mentioned that reservoir 12 in operation of the device, as above described, is filled with an alkaline solution of 1% by weight 3-aminophthal hydrazide containing 5% by weight sodium hydroxide. Reservoir 13 is filled with an aqueous solution containing 1% by weight hydrogen peroxide and 0.5% by weight potassium 'ferricyanide. Upon feeding and mixing of the reactive solutions in forming writing characters with the ball point pen, a visible light of greenish blue color is generated, permitting one to write by following the projected radiation coinciding with the writing characters.

It will be seen from the above description that the invention provides a writing device, which may be utilized to separately store solutions of certain chemiluminescent light-producing reactive components, and which is adapted to feed the solutions to the writing point of the device to admix the reactive solutions and permit their even and simultaneous flow onto a writing surface to provide luminous or visible light-emanating writing characters.

Various moidfications and alterations of the specific embodiment above-described may be made without departing from the spirit of the invention, the scope of which is defined by the appended claims. For instance, one modification would be to provide a triple chambered device one chamber of which could be utilized to separately contain an ordinary ink formulation, and in the other two chambers the separated solutions containing one each of the reactive components.

Having now set forth the invention, What I claim and desire to secure by Letters Patents is:

1. A writing device adapted to contain a plurality of separated fluids which are mixed upon discharge therefrom comprising: an elongated hollow body portion having opposite ends; removable closure means sealing one end of said body portion; a ball-mounting aperture formed in the opposite end of said body portion; a ball mounted in said aperture and rotatable therein; and means disposed within said body portion providing at least two reservoirs, each reservoir being adapted to contain a different fluid and to maintain its fluid separated from the 3,094,105 3 4 fluid in any other reservoir as long as said ball remains stationary but adapted to discharge and mix its fluid with References Cited in the file Of this Patent the fluid from at least one other reservoir on said ball when said ball is rotated relative to said body portion, said UNITED STATES PATENTS means disposed within said body portion including a separator having one end engaging said closure means in 5 2204778 Sturm June 1940 sealing relationship therewith and having an opposite end FOREIGN PATENTS terminating closely adjacent said ball and a seal disposed between said opposite end of said separator and said ball. 947,260 France 10, 1949 2.
