FOUNTAIN-PEN.

SPECIFICATION forming part of Letters Patent No. 367,752, dated August 2, 1887.

Application filed October 9, 1896. Serial No. 215,909. (No model.)

T 0 f/,ZZ 1071.011@ it may concernf Beit known that I, ALEXANDER FYFE, of

Paterson, in the county of Passaic and State, of New Jersey, have invented a certain new y and useful Improvement in FountainPens, of which the following is a specification.

The object of my invention is to provide a iountaiu-pen which will combine simplicity of construction, ease of operation, and cheapness-onc holding a good supply of writing iluid, with a flow capable of being regulated to suit the writer, and not as liable to get out of order as the fonntailrpens that are now 'in use.

In the specification reference will be. made to the accompanying drawings, which form a part thereof.

Similar letters of reference indicate like parts in the gnrcs-1, 4, 5, and 6.

The invention consists o1" a tubular holder or reservoir, a plug of rubber or other suit able material to iit or screw into the same, the nib or pen, and a covering lfor same, constructed as hereinafter specified, and as shown in the drawings.

Figure l shows a section of pen; Fig. 2, an elevation of modified form closed; Fig. 3, an elevation of pen, modified form, open; Fig. 4, a part section of pen, showing the orifice in plug open; Fig. 5, a part section of pen, showing the oriiice in plug partly closed; Fig. 6, a front view of plug, showing recess or depression in plug to receive the pen.

The pen completed consists of the tube or handle a, sliding sleeve a, to cover thepen, the reservoir ZJ, holding the ink b', rubber plug g, and the nib or pen h.

The inner walls of the tube or handle a are perpendicular for a short distance from the mouth, and then begin to taper or grow less in circumference, and the taper part thus formed is provided with a screw-thread, d'.

The rubber plugg is made straight part way, as seen by g2 in Fig. 4, to act as a guide in entering the tube a, and so as to iit in the straight part of the tube a. There is a slight depression or recess, g, in the plug g to receive the pen 71.. l

The plug g is made taper and provided with a screwthread, as shown by d in Figs. l, it,

and 5; but it is not tapered as much and is not as long as the taper part of the tube a,

which is provided with the screw-thread d.

The plug g is provided with the channels e fand` groove c, to allow the writing-fluid to pass from the reservoir b to the under surface of the pen h. The tlow of ink from said reservoir to the peu may be regulated and stopped entirely, if necessary, by screwing the rubber plug g into said tube a until the mouth of the 6o channel e is partly or entirely closed, as will be seen by comparing Figs. 4c and 5 in the drawings.

In Fig. a the plug g is not screwed in the whole way, and the passage-way e is wide open for the admission ot' ink from the reservoir b, and in Fig. 5 the orifice in the plugg is nearly closed, the plug being screwed in farther, and the fiow of ink is diminished accordingly. The

ink thus conducted to the pen fiows naturally In Fig. l the tube c is shown constructed SO with the portion marked k straight, and provided with an outer covering or sliding sleeve, a, which is drawn over the pen when not in use. Said sleeve may be secured in any suitable manner; but it is proposed to make the pen in another form, and secure thus, perhaps, a greater degree of convenience and usefulness. The invention is shown in the modified pen in Figs. 2 and 3. In Fig. 2 it is closed. In Fig. 3 it is open.`

In Figs. 2 and 3 letters of reference refer to similar parts.

In the modified form, b2 is the reservoir end of pen, and b" is the plug and pen end. Midway between the pen and the end of the reservoir b, which is indicated by the dotted line, there is the enlarged part or shoulder a on theholder and reservoir; but said shoulder` a may be placed at any desirable point. b2,

the reservoir end, and bs, the plug and pen 10o end, are of the saine size 'that is7 the reservoir and holder is the saine dimension on each side of the shoulder it, and the sleeve or case a iits ou the pen and plug ycud bf when not in use, as is shown in Fig. 2, in which the dotted lines indicate the position of the plugl g and the pen h, the shoulder n forming a. stop for the slee"e or case a, and the reservoir end b2 being exposed. In this forni the pen may be carried about the person, and in order to use the pen the sleeve or ease is removed from the pen end b and placed on the reservoir end b2, as is shown in Fig. 3.

rhe modification consists merely in` the shoulder n and the case or sleeved', to receive either end of the reservoir and holder.

the plug and tube, all substantially as shown and specied, and for the purpose set forth.

2. In a fountain-pen, a tubular reservoir having a shoulder to act as stop for sliding` cover, and the interior of Which is, for a short distance from the mouth, of the saine circumfercn ce, then gradually tapering for ashort distance, the taper part provided `.vith a screwthread, in combination with a rubber plug partly straight and partly taper, having a screw-thread and a slight depression to receive broad end of gold or steel pen, said plug; being provided with an opening extending from the inner end of said plug through the saine and upward to the under surface of pen, the opening or passage'for ink through the plug to be increased or diminished in size by screw ing the lplug into the tubular reservoir, all substantially as shown and specified, and vfor the purpose set forth.

ALEXANDER FYFE.
