Figure 1 is a view illustrating a fountain pen In the drawing A represents the usual barrel structure of a type to which my improvements of a fountain pen,- receiving a tubular cap B, may b applied; which carries the usual ink bag C, employed Fig. 2 is a view illustrating the parts of the with modern fountain pens. In the usual p combination nib and feeder holding element tice, this tubular cap B receives the pen nib 88 which may be employed in the form of strucand the feeder associated therewith; such feeder ture shown in Fig. 1; member fitting the bore of the tubular cap very Fig. 3 is a sectional view on the line III-III, snugly and confining the end of the pen nib Fm between its surface and the wall of said bore.

To facilitate removal and replacement, the detachable shell may have aknurled flange 1.

The feeder member may be of any approved type, and it may be inclamped relation with respect to the pen nib before the latter is inserted in the carrier; the pen nib shown in Figs. 4 and 5 having wings 2* arranged to embrace the body of the feeder which may be recessed for such purpose as indicated at 3*. It will be understood, of course, that the arrangement of pen and feeder illustrated in Fig. 4 wherein the pen is shown as provided with wings clamping the feeder, may be employed in the form of carrier illustrated in Figs; 1 and 2.

The carrier 1 has a rear wall 1" against which the feeder may abut; such wall having a curved slot 1, to register with the ink groove 3", and the dimensions of such slot may be such as to enable easy assembly of the parts with a fully open passage for the ink.

The connection between the carrier 1 and the pen barrel or the tubular cap B at the end of the pen barrel, may be of any suitable type within the range of fountain pen construction. It may be a threaded joint as indicated in Figs. 1 and 2, with one or a plurality of continuous, or interrupted, threads, or it may be a slip joint as shown in Figs. 4 and 5. Any form of connection that will insure the desired liquid tight closure between the inserted or applied part carrying the nib and feeder and the tubular cap carrying the ink bag is within the scope of my invention.

As may be readily understood, several of my improved nib carriers may be sold with a fountain pen of a construction designed to receive the same as articles of merchandise; similar carriers with any desired form of pen nib being also sold for application thereto, so as to provide replacements for the original structure.

While I have illustrated fountain pens of the type having collapsible ink bags which may be filled automatically upon retraction of collapsing means, I do not wish to be limited thereto and other forms of fountain pens, among which may be mentioned those filled by suction by the action of a piston member, may be equipped with the unit nib and feeder carrying member forming the subject of my invention.

It is, of course, within the scope of my invention to employ gold nibs in connection with the unit member I have devised, and the claims are intended to cover unit members for connection with the barrel of fountain pens containing ink supplying means, whether such nibs are of steel or of any other metal. In like manner, the feeder element may be of any type that will properly perform its function. It may be entirely different from the form of feeder disclosed, which representation is more or less diagrammatic and is intended to indicate means for performing a function rather than the member that will be actually employed for such purpose.

I claim:
