Beit known that I, WILLIAM R. RoTrrwnLL, a citizen of the United States, residing at the city of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Fountain-Pens, of'which the following is a specilication. A

My invention has relation to the provision of a fountain type of pen with a detachable device for not only clamping the pen within the barrel or holder for use, but also providing the necessary air-vent for the ink in the reservoir of the holder to permit of the antomatic flow or feed of the ink .in regulated quantity from the reservoir of the holder to the pen along one surface of the device, whereby reliable working of the pen is uniformly insured; and in such connection my invention relates to the particular construction and arrangement of the device for automatically feeding, for holding the pen in required p0- sition in the holder, and for venting with air the ink in the reservoir of the holder, as hereinafter more fully described and claimed.

The nature and characteristic features of my invention will be more fully understood from the following description, taken in connection with the accompanying drawings, forming part hereof, in which- Figure l is longitudinal sectional view of a fountain-pen, showing the operative parts as well as the device of my invention in elevation. Fig. 2 is a vertical central sectional view of so much of a fountain type of pen as will serve to illustrate the application of my invention thereto. Fig. 4 is a transverse sectional view of the pen holder or barrel, and an under plan view of the pen and the device of my invention in application. Fig. 4 is a crosssectional view through the barrel, pen, and device on the linee 4 of Fig. 3; and Fig. 5 is a top or plan view of the detail construction of the automatic feeding, holding, and air-venting device of my said invention.

Referring to the drawings, A is the fountain-pen barrel within which the reservoir for ink is provided, and which barrel or holder may be of any of the well-known types of such character of pens.

. :iisthepem which may bel-'ofl'any 'ordi-` nary type. n

' C isthe device of my invention, made of rubber, ber, papier-mch,or other preferred material capable of being bent under the influ- 5 5 ence of heat for causing the same to assume the required shape or condition for being adapted for use in connection with a pen and its holder or barrel, so as to hold the pen snugly to place in the barrel or reservoir-holder A, and so .arranged as to supply the necessary amount of air to the ink in the barrel A to permit of the free ow or feed of the ink from the reservoir as required along one surface thereof to the pen B. This device C consists of a narrow oblong fiat strip c, slightly curving upward from the rear portion to the tapering front blunt-pointed end c', as clearly illustrated in Figs. 2 and 5. The respective sides c2 and c3 are preferably beveled off, as in Fig. 7o 5, to fit the under surface of the pen, as illustrated in Fig. 3, and the top surface of the device is arranged so as to form with the pen in position in the holder a channel or way ci, so that when the device C is in operative position, as illustrated, for example, in Figs. l and 3, the ink will flow or be fed automatically from the holder-reservoir A along the top surface ci of the device to the point of the pen B for writing by exerting a mild hand- 30 pressure on the holder.

The rear portion of the device C is 'bent either upward or downward onto the main body portion of the device into preferably a coil c5, Figs. 1 and 2. The under surface of 85 the coiled portion c5, at the respective edges, is beveled 0E, so as to snugly fit the holder, as clearly illustrated in Figs. 3 and 4, and while the coiled portion forms a means for engaging with the sides or edges of the pen for snugly yet detachably holding the pen in the barrel or holder it at' the same time from the under side permits of free ingress of air at c between the barrel A and the coiled portion c5 of the device into the reservoir of 95 the-pen barrel or holder, whereby as so arranged the 'iiow or feed automatically of ink to the pen from the reservoir whenv the holder has been caused to assume the required angle of inclination is always insured. 109

Having thus described the vnature and objects of my invention, what I claim as new, and desire to secure by Letters Patent, is#

1. In a fountain-pen, a holder, a pen and a device, consisting of a flat strip tapering to with the pen a channel or way, and the oppo site end formed into a coil having beveled sides, substantially as and for the purposes described. Y

3. In a fountain-pen, a device consisting of a fiat narrow strip of pliable material, one surface forming with the pen a channel or way, and the rear of the device formed into a coil interposed between the pen and holder, y

substantially as and for the purposes described.

In testimony whereof I have hereunto set my signature in the presence of two subscribing witnesses.
