Albrecht, Faireld, Conn., assignor to Almar Industries, Inc., Norwalk, Conn., a corporation of Connecticut Filed Oct. 22, 1965, Ser. No. 500,909 7 Claims. (Cl. 401 -148) ABSTRACT F THE DISCLOSURE A .marking device having a nib capable of capillary action is provided with a radial flange which engages and extends over a substantial area of the end of an ink bearing filler to compress the same in response to the writing pressure on the nib to produce a pumping action for controlling the supply of ink to the nib.

It is an object of the present invention to provide a marking device which is simple in construction, and` comprises a minimum number of parts which are easily manufactured and assembled and which provide a novel coaction to produce a metering of the ink or the like marking fluid therefrom.

This is accomplished by providing a marking device formed with four readily molded parts which can be quickly assembled and when assembled have a novel coaction whereby the writing pressure applied to the Writing point meters the amount of ink provided thereto.

Further, the device of the present invention can be used per se as a marking device or can be used as a cartridge to be enclosed in a holder.

Other features and advantages of the invention will be apparent from the specification and claims when considered in connection with the accompanying drawings in which:

FIGURE 1 shows a side View of the marking device.

FIG. 2 shows an exploded view of the elements of the marking device in the order in which they are assembled.

FIG. '3 is a longitudinal sectional view of the marking device.

FIGS. 4, 5 and 6 are transverse sections taken along lines 4-4, 5--5 and 6 6 of FIG. 3.

FIG. 7 is a view of the marking device disposed in a holder therefor.

As shown in the drawings, the marking device of the present invention comprises four simple parts, namely, a barrel 10, a nib 11, a filler 12 and a closure cap 13.

While the barrel may be made from metal or other like material, it is at present preferred to form it as a molding in part or in Whole of suitable plastic material which will not react with or have any effect on the marking material enclosed therein. As used herein the term ink shall be used to designate said marking material whether it be ink or other suitable marking or writing fluids. As shown in FIG. 3, the barrel 10 is an elongate tubular body 15 provided adjacent the forward end with an inwardly directed portion which forms a rearwardly facing shoulder or abutment means 16. While this can be formed as spaced lugs, it is herein illustrated as a flange 17 forming a part of the end wall 15a for the barrel. In the preferred form of the invention a cylindrical neck 18 extends from the end Wall, as shown in FIG. 3, and terminates in a tapered portion 19 provided with a nib receiving and supporting passage or aperture 20 at the end thereof through which the nib projects and is supported in writing or marking position. If desired a finger gripping surface 15b can be provided adjacent the end Wall 15a.

With respect to the nib, while this may be formed of '3,355,239 Patented Nov. 28, 1967 ICC various types of material capable of capillary action, such as felt and the like, it is at present preferred to form it of a plastic material capable of feeding the ink by capillary action. Some of these materials are polyethylene, polypropylene, nylon and acrylic resins. In the preferred form of the invention, however, it is formed from tetrafluoro ethylene or the like material (Teflon). The nib 11, as shown in FIGS. 2 and 3, comprises an elongate rod 25 having a Writing point 26 at its forward or outer end. Disposed on the nib at a point located between the ends thereof is a radial -an-ge 27. While the flange can be a separate part and forced on or otherwise secured to the rod, it is at present preferred to form it integrally with the rod. The portion 28 of the rod extending rearwardly of the flange is preferably slightly tapered so as to assist in its insertion into t-he ller as will be explained.

The filler material comprises a rod of material forming a porous body capable of retaining a supply of and of releasing therefrom a marking fiuid or ink by capillary action and/ or by pressure thereon. In the preferred form of the invention the filler comprises a rod 29 of cornpressed cellulose material impregnated with ink. This filler is resilient and is positioned within the barrel with its forward end abutting the radial flange 27 on the nib with the rear end 28 of the nib extending into the filler a substantial distance as shown in FIG. 3 to provide a sufficient contacting or engaging surface therebetween to effectively transfer ink from the filler to the nib for transmission therealong to the Writing point as required. The rear end of the barrel 10 is closed by the plug 13. rl`his plug is preferably molded from material compatible with the barrel and has -a neck 30 to be inserted in the barrel and a flange 31 forming a shoulder 32 thereon. The plug is inserted into the end of the barrel until the shoulder engages the end of the barrel and the neck is in sealing relation with the barrel to close the end thereof. The plug seals the rear end of the barrel and is then fastened in position by suitable adhesive or by heat sealing means.

The forward end of the filler engages the ange 2.7 and normally presses the flange 27 against the abutment or shoulder 16 and locates and supports the writing point in writing position. In accordance with the present invention the flange is pressed against the abutment with a yielding pressure. While this can be accomplished by inserting a spring between the end of the filler and the plug, in the herein preferred form of the invention the neck has a length, which when the plu-g is secured in position will place the filler under a slight compression to provide suilicient force to yieldably hold the nib in its projected position; yet permits the nib to move inwardly slightly under Writing pressure to control the ow of ink thereto as will be described.

The cylindrical neck 18 of the barrel is of such a length as to sealingly receive a cooperating portion of the usual cap (not shown) which is inserted thereover to enclose the end marker to prevent evaporation of the ink or marking uid.

From the foregoing it Will be seen that the device of the present invention comprises a minimum of parts which can be readily molded or formed from suitable materials. The device can be easily and quickly assembled, as shown in FIG. 2, by merely inserting the nib and then the filler in the rear end of the barrel and applying the closure plug and securing the same to provide a simple yet effective marking device.

. In order to permit a ready flow of the ink from the barrel, vent means is provided. While this may take the for-m of passages in the nib or a flat side on the nib where it passes through the aperture at the end of the taper, in the herein illustrated form of the invention venting passages are formed by a plurality of slight grooves 4f) formed in and extending longitudinally along the engaging wall 41 of the tapered portion which engages and supports the nib adjacent the writing point thereof as shown in FIGS. 3 and 6. Also, as shown in FIG. 4, the radial flange 27 is provided with notches 42 which provide for venting of the barrel at this point and the filler has a longitudinal groove 29a in the body to complete the venting action.

It has been discovered that with normal writing pressure, ink or marking fluid will flow from the filler by capillary action and be transferred to the end 2S of the nib embedded therein. The nib will then, by capillary action, transfer the ink or marking fluid to the writing point 26 to provide a relatively fine line. However, upon an increase in the writing pressure the nib will move inwardly slightly and compress the end of the filler surrounding the nib portion 28 and adjacent the flange 27. This will, in effect, squeeze and/ or pump out the ink from the filler at a greater rate than would be achieved by normal capillary action of the filler. ln this manner the nib is then supplied with a greater amount of fluid which it passes to the end and provides for a heavier writing line. However, as soon as the increased writing pressure is removed, the device returns immediately to its normal amount of ink and produces the relatively fine line. Thus, it will be seen that the novel combination of elements produces an accurate metering of the ink from the filler depending upon the writing pressure used.

`In some circumstances it may be desired, for example, to provide a more rugged and/or ornate device or one of a higher quality. This can be accomplished by using a holder, preferably a rigid ornamental metal casing 60, and the marker above described may be used as a cartridge 61 for the holder. Such a device is shown in FIG, 7 wherein there is a two-part holder 62, 63 which parts are threaded together as at 64.. The holder has a closed end 65 at the rear end and a tapered portion 66 at the forward end adapted to receive the tapered portion 19 of the marking unit with the nib projecting through an opening 67 and beyond the housing. This holder can be of metal suitably plated or treated or otherwise decorated to provide an ornamental appearance so as to produce, in effect, a deluxe marking device. The cartridge can, by separation of the parts 62, 63, be readily assembled with the holder and can be removed and/or replaced to provide a change in color or replenishment of the ink.

From the foregoing it will be seen that the device of the present invention can `be formed from readily moldable parts which can be quickly and easily assembled and which provide a unique metering of ink during the writing operation in response to varying writing pressures.

Further, the marking device of the present invention can also be used as a cartridge in connection with an ornamental holder to provide a lmarking device which is rugged and/ or ornamental.

Variations and modifications may be made within the scope of the claims and portions of the improvements may be used without others.
