Another object of the invention is to provide an improved marking device which will prevent leakage of the marking material. I

Another object of the invention is to provide an improved markingdevice which will supply marking material'in adequate quantities to make broadlines.

Another object of the invention is to provide an improved marking device which maybe easily and economically manufactured.

Other objects will hereinafter appear. I e

The invention will be better understood from the description of one practical embodiment thereof, illustrated in the accompanying drawings, in which:

Figure 1 is a side elevation of a marking device resembling a fountain perishown to a scale substantially greater thanactual size;

Figure 2 is a view,-partly in elevation and partly in section taken on the line II=II=oi Fig- 3 Claims; (01; 15-139) 2 slightly modified form of pen for use with a sealed capsule containing ink.

As above suggested, the marking device illustrated resembles in general contour and size, a conventional fountain pen. It consists of a reservoir, defined by a hollow tubular body or barrel I, closed at one end by a head 2 shown as formed unitarily therewith and carrying at its other end the material applying parts to be hereinafter described.

A cap, consisting of tubular sleeve 3 and an end 4, which may, if desired, be closed by a plug 5 threaded therein, may be secured to the barrel by means of the threads 6 formed on the exterior of the latter and conjugate internal threads 1 formed within the end of the sleeve 3.

A clip, consisting of a cap-embracing band 8, a spring 9 and a lever portion It, is shown as embracing the cylindrical exterior of cap 3 to retain thedevice in the pocket when not in use.

Threaded into an internal thread II formed in the open end of barrel 1 is a bushing 12 having a tapering or fusiform external surface [3 and being provided with a central or axial bore I1 which extends through the front or lower, end of the bushing.

This bore is expanded into a counter-bore l8, also coaxial with the bushing, and opening into the interior of the barrel. n

At the junction of the bore l1 and counterbore i8 is formed a frusto-conical shoulder l9 which constitutes in effect a valve seat engaged by ball valve 2!] positioned in the counter-bore.

Valve 20 is urged toward the seat 19 by a helical compression spring 2i held in the counterbore by a plug 22 threaded into the thread 23 formed at theinner end of the bushing.

The plug 22 is centrally perforated as'indicated at 24 to permit the passage of the ink or other marking material.

Frictionally retained within the bore i1 is a square strip of absorbent material, such as felt, 25 which projects a substantial distance beyond the end of bushing 12 and the inner end of which bears upon the ball valve 20. This absorbent material 25 constitutes in efiect a stylus or applicator by which the marking material is applied, and serves as a, substitute for the conventional metal point or nib of the ordinary fountain pen.

In operation, when the user desires to write or otherwise mark, he removes the cap, grasps the barrel in his hand as with an ordinary pen or pencil, and presses slightly down upon the object on which he wants to mark.

This pressure pushes the stylus 25 inwardly,

raising the ball 20 from its seat I9, and so permitting ink to flow past the ball at its sides to the stylus, which it aturates.

This ink is then drawn by capillary attraction through the stylus to its lower end, from which it is delivered to the article to be marked as the user moves the device along this article.

If too much ink is being delivered, and the user wishes to limit this quantity, he has merely to lessen his pressure upon the stylus, which will permit the spring 2| to return the ball 29 to seat l9, effectively shutting oh the supply of further ink and allowing the stylus to deliver only that which it has already absorbed.

If on the other hand, he requires more ink, proper pressure on the stylus will unseat the ball 2:9 and provide for an additional supply.

The slight sector-shaped spaces in bore I? do not permit the ink to run out, as these are too small to permit the passage of a full sized drop, but any ink which enters these passages is absorbed by the stylus and so conveyed through it to its bottom or marking end.

It will be apparent that the user can make lines as broad as the end of the stylus, or, by tilting the device, may cause only a corner of this to contact the object he is marking, which corner will make a correspondingly finer line.

At all times when the article is not in use, as when it is being carried in the pocket, not only is the cap applied to keep the stylus or wick from contacting the users clothing, but the ball valve is seated and retains all ink but that which has been absorbed in the stylus within the body I.

For convenience in disassembling, the plug 22 is slotted as indicated at 26, so that a screw driver or other tool may be inserted in the slot to remove the plug from the bushing, and after removal the spring and ball may easily be removed by pushing upwardly on the stylus or by inserting a rod through the bore H.

In Figure 8 the ink is supplied in a sealed capsule which fits within the hollow of barrel 1, this capsule being shown as a thin walled cylinder with disc-like ends, the cylinder wall being indicated at IM and the lower end at I02.

The upper end of bushing H2 is formed into a sharp annular ridge H3, which is notched at one or more spaces along the periphery as indicated at l M to provide a cutting edge, which will sever a part of the disc I 62 and press it inwardly as indicated at N13 to permit ink to pass to the stylus or nib. Thus the unsealing of the capsule or cartridge is accomplished merely by inserting it into the barrel and tightening the bushing I I2 into place.

While I have described the illustrated embodiments of my invention in some particularity, obviously many others will readily occur to those skilled in this art, and I do not, therefore, limit myself to the precise details shown and described,

but claim as my invention all embodiments,

variations, and modifications thereof coming Within the scope of the appended claims.

I claim:

1. A marking device comprising a tubular barrel, a bushing secured to one end of said barrel, a closure at the other end of the barrel, the bushing having two co-axial bores, one extending through its outer end and the other being of larger diameter and communicatin with the interior of the barrel, an absorbent stylus within the first mentioned bore and projectin beyond the outer end of the bushing, a ball valve in the second mentioned bore adapted to be urged norm'ally into contact with the inner end of said stylus and movable thereby, a spring pressing the ball valve toward the stylus, and an abutment within the bushing engaging the innner end of the spring.

2. A marking device comprising a tubular barrel having a closed end, a bushing threaded into the open end of the barrel, the bushing having an axial bore extending to its outer end and a larger co-axial counterbore communicating therewith and opening into the interior of the barrel, an apertured plug threaded into the inner end of the counterbore, a coil spring having one end thereof abutting said plug, a ball valve be tween the spring and the juncture of the bore and counterbore, said valve having engagement with the other end of the spring, an absorbent stylus within the bore with its outer end projecting and contacting with its inner end the ball valve.

3. A marking device comprising a tubular barrel having a closed end, a bushing threaded into the open end of the barrel, the bushin having an axial bore extending to its outer end and a larger co-axial counterbore communicatin therewith and opening into the interior of the barrel, an apertured plug threaded into the inner end of the counterbore, a coil spring having one end thereof abutting said plug, a ball valve between the spring and the juncture of the bore and counterbore, said valve having engagement with the other end of the spring, a rectangular absorbent stylus frictionally held within the bore and projecting outwardly thereupon, said stylus contacting with its inner end the ball valve.
