FOUNTAIN-PEN.

$PECIF ICATION forming part of Letters Patent No. 393,049, dated November 20, 1888.

(No model.)

To all whom, it may concern.-

Be it known that I, JOHN T. WILcoX, of Leominster, in the county of Vorcester, State of Massachusetts, have invented acertain new and useful Improvement in Fountain-Pens, of

which the following is a description sufficiently full, clear, and exact to enable any person skilled in the art or science to which said invention appertains to make and use the 13 same, reference being had to the accompanying drawings, forming part of this specification, in whieh Figure 1 is a side elevation of a 'fountain pen embodying my improvement, the pen [5 proper and lower portion of the body or holder being shown in section; Fig. 2, an enlarged front elevation of the pen proper detached; Fig. 3, an enlarged vertical longitudinal section of the pen proper, taken on the dotted line 00 a: in Fig. 2; Figs. 4, 5, and 6, side elevations showing the application of the improvement to various forms of pens, the upper portion of the body or holder and the bulb in Fig. 6 being shown in section, and the holders in Figs. 4- and 5 as broken away to show the interior; Fig. 7, a vertical longitudinal section of the lower portion of the pen shown in Fig. (i, and Figs.'8 and 9 sectional views showing modifications of the improve ment. I

Like letters and figures of reference indicate corresponding parts in the different figures of the drawings.

My invention relates more especially to the class of pens known as fountain-pens, al-

though applicable to various other forms or kinds; and it consists in certain novel features, as hereinafter fully set forth and claimed, the object being to produce a more effective 0 and otherwise desirable article of this character than is now in ordinary use.

The nature and operation of the improvement will be readily understood by all con= versant with such matters from the following explanation:

In Fig. 1, A represents the body or holder of the pen, and B the pen proper, both of these parts being composed of the composite material or vulcanite known in the arts and to the trade as hard rubber. The holder is hollow or provided with a reservoir, 40, and is closed at its upper end, its lower end being left open to receive the pen proper.

The pen proper (see Figs. 2 and 3) consists, essentially, of the pointf, retainer :1, and plug 9, the plug being omitted in all forms of the pen excepting those provided with a fountain or reservoir. The retainer 2 and point are integral or formed in one piece, their upper portions being united and shaped so as to constitute a short tubular stock, 15, in which the plug is disposed; but when the pen is not provided with a reservoir, as 40, the stock may be made solid or its opening or tube may extend but partially through it from the lower end upward'to form a socket, as 14, for the ink. The point is tapered and pro 'vidcd with a slit, 1;,whieh opens outward centrally through its nib or extreme lower end and extends upward to a terminal hole, t, in the usual manner. The retainer, which is somewhat shorter than the point and also tapered, is bent or curved inward to bring its lower end in close proximity to the rear face of the point. The plug 9 is preferably composed of hard rubber and is disposed within the pen proper just above the hole t. It may, however, be placed in the lower portion of the holder, if desired, in certain forms of the pen and perform the same functions. A diagonally-arranged hole or duct, 45, is formed in the plug, the lower end of said duct being preferably so disposed as to open contiguous to the hole t, thereby causing the ink passing from the reservoir 40 through said duct to be delivered directly to the point f. The duct may, however, be formed at the center of the plug, as shown in Fig. 9, or at one side, as shown at Fig. 8, or in any other suitable position, if desired.

The retainer z serves to increase the capillary action of the pen proper and enable it to hold or retain a larger quantity of the ink than would be possible without its use.

When the pen is designed for desk use only, the point f and retainer 2 are formed integral with the body A, as shown in Figs. 4 and 5, the plug g being omitted and the pen used by dipping it in the ink after the manner of ordinary steel pens.

In Fig. 1 the pen proper, B, is shown as detachable from the holder or body A;. but it is sometimes formed integral therewith,as shown in Figs. 6 and 7, the plug 9 in such case being employed in substantially the same manner as in Fig. 1.

In preparing the pen shown in Fig. 1 for use the pen proper, B, is removed from the holder A, the holder inverted, the reservoir filled with ink, and the pen proper again inserted in the holder.

The pen shown in Fig. 6 is provided with an elastic bulb, D, the upper end of its body A being open and. inserted in the neck of said bulb. To fill its reservoir 40, the bulb is compressed, the pen proper, B, inserted in the ink, and the bulb permitted to expand, the bulb being left in position on the body when the pen 1s 1n use.

The stock 15 of the pen proper may be inserted in the holder A, as shown in Figs. 1 and 8, or the holder inserted in said stock, as shown in Fig. 9, by a slight change in the construction of the parts.

A sleeve, 24., composed of rubber, cork, or other suitable material,is employed to enlarge the body A when desired.

In constructing the pens ordinary hard-rubber tubing has been found to be convenient and well adapted for the purpose.

The holder A may be made of other mate rial than hard rubber, if preferred,when the point and retainer are not formed integral therewith.

A cap or guard, O, is provided for each of the pens in the usual manner, the upper and ite or vulcanite materials of a similar nature may be employed; but the rubber has been found most desirable on account of its cheapness, great durability, and the ease and facility with which it may be worked.

Having thus explained my invention, what I claim is- 1. In a fountain-pen, the elastic bulb D, in combination with the body A, provided with the reservoir 40, point f, retainer 2, and plug 9, having the duct 45, said point and retainer being composed of hard rubber and formed integral or in one piece, substantially as described.

2. In a fountain-pen, the holder A, closed at its upper end and provided with the reservoir 40, the pen proper, B, having the curved retainer 2 and tapered point f, provided with the slit '5, and the plug 9, disposed in said pen proper and provided with the duct 15, said point and retainer being composed of hard rubber or similar material and formed integral or in one piece, all constructed,combined, and arranged to operate substantially as described.
