Description
Specification Today, many recorder instruments utilize instru-ment recorder pens havin~ large volume ink supplies in order to minimize time spent on refillinp, of the ink res-ervoirs. Often, the nature of the recorder instrument does not allow the positioning of such a large volume l~eservoir close to the pen writing tip. Thus, there has been a need in the recorder instrument field for a large volume ink supply pen wherein the reservoir is separated from and not positioned near the writing tip.
10Many recorder instrument pens deliver ink from an ink reservoir to a remote writing tip via the capillary action of either an intermediate conduit or the writing ~ip itself. Three of such pens include: U.S. Patent 3,480,372 (Kenny et al.); U.S. Patent 3,264,652 (Squier);
15and U.S. Patent 1,720,226 (Lovejoy). In many instances, ` such pens have a tendency to accumulate too much ink at the writing tip, causing wet writing and bleeding.
- Further, none of these pens are disposable either in whole or in part. Moreover, because each of these pens equire the use of a liquid ink reservoir, such pens some-times exhibit leakage problems around the reservoir supply.
` Thus, it is an obJect of the present Lnvention to provide a recorder instrument pen having a writing tip re- -mote from its ink supply that delivers ink to a writing ~5 tip via capillary action that does not bleed or wet write on the writing surface.

Further, it is a particular object to provide such a pen wherein the amount of pen servicing ~i.e~
cleaning, delinting and refilling) is kept to a minimum.
Moreover, it is the specific object of the pre-sent invention to provide a recorder instrument pen having a writing tip remote from its ink supply wherein either the entire pen assembly or component parts thereof are disposable~
These and other objects, which will become apparent in the further course of the specification, are met, by the three-Phase recorder instrument pen of the present invention. Briefly, the pen includes three phases, each containing capillary material. The phases are arranged in order of succeeding degrees of capillarity.
~hus, the ink is drawn from the reservoir through inter-mediate capillary material having a higher degree of capillarity than the reservoir. In turn, the generally -porous writing tip draws the ink from the intermediate `~
capillary reservoir to make contact with the writing surface.
2~ More specifically, the invention consists of a pen, designed to include a writing tip remote from the pen's ink ` supply, including in combination: (a) a reservoir body; (b) capillary reservoir materiàl, housed inside of said reservoir body, having a degree of capillarity suitable to retain an ink supply under normal handling, yet able to release the ink to a member of preferred capillarity; (c) an intermediate conduit having a distal end and a proximal end; (d) intermediate capillary material, housed inside of said intermediate conduit having a higher degree of capillarity than said capillary reservoir material, said intermediate capillary material to ~ . .

have both a distal and proximal end; (e) a generally porous writing tip, having a higher degree of capillarity than said intermediate capillary material, said distal end of said intermediate capillary material mating with said capillary reservoir material, and said proximal end of said intermediate capillary material mating with said writing tip.
In one form of the invention, the entire pen assembly is made of an inexpensive, lightweight, molded or extruded plastic. Thus, the entire pen assembly itself is disposable.
In another form of the invention, both reservoir and a writing tip cartridge, housing the generally porous writing tip, are made of disposable material, thus facili-tating ea replacement of two pen components.

Venting may also be provided in a path along tl~e writing tip as is typical in prior art disposable markers.
Capillary reservoir material 6 consists of capillary material. Typically, fibrous material such as cellulose acetate is utilized.
The distal end of intermediate conduit 8 extends perpendicularly from reservoir body 4. Intcrmediate `` capillary material 10, of higher degree of capillarity than reservoir material 6, mates with reservoir material 6 inside of reservoir body 4.
The proximal end of intermediate capillary material 10 angularly mates with generally porous writing tip 12 housed inside of tip sheathing 14. I~riting tip 12 has a higher de~ree of capillarity than intermediate capillary material 10. Thus, ink stored in reservoir material 6 is drawn by capillary action through inter-mediate capillary material 10 to writing tip 12 to make contact with a writing surface.
Pen 2 is made from inexpensive, molded plastic `~ 25 components that have been heat sealed together. Thus, when the ink supply runs out, the entire pen may be discarded and replace~ by another disposable pen.

Fi~ure 2 shows a preferre~ embodiment of the three-phase ink circuit marker pen of the pre.sent invention.
Here, pen 16 inclucles cyclindrical body 4 housing reservoir 6. Cartridge holder 18, containing an aperture therein, is sealingly snapped over one end of cylindrical body 4.
Rigid intermediate conduit ~ houses intermediate capillary material 10.
The distal end oE rigid intermediate conduit 8, inserted through the aperture in cartridge holder 1~, pierces one end wall of cylindrical barrel 4. Intermediate capillary material 10 mates with re~servoir material ~ inside of reservoir body 4. Thus, a tight closure, made by both the snug Eit of rigid intermediate conduit 8 ~ithin cartridge holder 18 and the sealing engagement of cartridge holder 18 over the end of cylindrical body 4, is formed at the area of entrance of rigid intermediate conduit 8 into cylindrical hody 4.
` ' The proximal end of intermediate conduit 8 and inter-mediate capillary material 10 are snugly positioned inside of writing tip cartridge 20, causing writing tip 12 and intermediate capillary material 10 to mate therein. Pointer 22, sealingly attached to intermediate conduit 8, provides a convenient observation guide so that the recorder instru-ment may be read while the pen is in use. Optional vent 24 may be pierced so as to allow air to enter the pen to replace the ink used as the pen is writing. -In this preferred form of the invention, both reservoir body 4 containing reservoir material 6 and writing tip cartri(lge 20 containing writing tip ]2 can be :

1143-75 1~1'7~
, made of inexpensive disposable matcrial Therefore, pen 16 can be easily serviced by merely attachin~ either a new reservoir body 4, wri~ing tip cartridge 20, or both. This factor decreases potential instrument down time.
Figure 3 shows still another embodiment of the presen~ invention~ Here, pen 26 comprises a bucket or "U"
shaped reservoir body 4. Reservoir body 4 contains reservoir material 6 (again, all forms oE ~he invention contain reser-voir material having a degree oE capillarity sufficient to retain an ink supply under normal handling, yet able to release the ink to a phase of preferred capillarity).
Reservoir body 4 is shaped to include a laterally extending intermediate conduit receptacle 28. Also, the top o~ reser-voir body 4 is covered by a heat sealed plu~ 30 containing pierceable vent 32 so as to provide for optional pen venting.
Intermediate conduit receptacle 28 contains bore 29, through which the distal end of intermediate capillary mater-ial lO extends to mate with reservoir material 6 within reservoir body 4. In this embodiment of the invention, intermediate capillary material lO extends throu~h the cen-ter of reservoir material 6, thus providin~, a large area mating surfàce. However, such a large matin~area may not be required. The distal end of intermediate conduit 8 is received inside of intermèdiate conduit receptacle 28 by larger bore "9a concentrically drilled ~i.th bore 29.
The proximal ends of both intermediate conduit 8 and intermediate capillary material 10 contained therein, mate with tip cap assembly 32. Tip cap assembly 32 includes :

tip cap projections 34, 35, ancl tip cap body 36 The proximal end of intermcdiatc capillary material 10 fits inside of tip cap projection 35, while intermediate con-duit 8 fits over tip cap projection 35~ Writing tip 12, S housed inside of the other ~ip cap projection 34, angularly mates with the proximal end of intermediate capillary material 10 inside of tip cap body 36~ A small portion of writing tip 12 extends downwardly from tip cap pro-jection 34 so as to contact a writing surface~
Figure 4 shows two pens, similar to the marker illustrated in Figure 1, in tandem In this figure, it is apparent that writing tip 12 may mate with intermediate capillary material 10 in any angular disposition to efficiently deliver ink to writing tip 12~ In this ~igure, the length of reservoir body 4, intermediate conduit 8, writing tip 12, and tip sheathing 14 are different for each pen~ Thus, in actual use, one pen may pass over top of the other, allowing pens to be used in conjunction with one another on dif~erent arms of the same recorder instru-ment.
