FOUNTAIN-PEN.

' Specification of Letters Patent.

Patented June 12, 1906.

Application filed August 18, 1905. Serial No. 274,760.

To all whom it may concern:

Be it known that I, ALFRED HALL, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Fountain-Pens, of which the following, taken in connection with the drawings, is a specification.

My invention has for its object the production of a fountain drawing or ruling pen adapted to be used by draftsmen and one in which an even flow of ink is fed to the pen and which may be easily and readily adjusted to produce heavy or light lines, as desired.

In the accompanying drawings, forming part of this specification, and in which like letters of reference indicate corresponding parts, I have illustrated one form of device embodying the essential features of my invention, although the same may be carried into effect in other ways without in the least departing from the spirit thereof, and in these drawings Figure 1 is a central vertical section through the pen. Figs. 2 and 3 are details of the inner parts thereof.

In carrying out my invention, A represents the ink-barrel of the pen, having screwthreads a upon the inner periphery near one end thereof. A cylindrical extension B, screw-threaded at the top thereof, is attached to the barrel of the pen, as shown. This cylindrical extension is provided with circumferential'shoulders'b b b of different diameters, each of which serves a purpose hereinafter described.

A collar C surrounds the cylindrical extension B and is held thereon by friction. IVhen said collar is in position, the top edge thereof abuts against the shoulder 12.

An annular cone-shaped member D surrounds the lower portion of the extension B and is held by friction between said extension and the collar C. This cone-shaped member is adjustable vertically upon the extension C, being limited in its upward movement by the shoulders b. Screw-threads d are provided upon the inner periphery of this coneshaped member near the top thereof for a purpose hereinafter described.

A feeding-tube E, having a head E screwthreaded upon the outer peri hery thereof, is inserted into the cone-shape member D and is held in position by the screw-threads d. An opening e is arranged in the head E, so

that when in position the opening is prefer ably adjacent to the inner wall of the inkbarrel A, as shown in Fig. 1. Re'cesses e e are provided in the head E.

F F are the nibs of the pen, which are preferably bent at the upper ends thereof, as shown, and inserted into the recesses e of the head E. The outer faces of the nibs are contiguous with the inner periphery of the member D and are regulated thereby.

A heavy orlight line may be drawn with this pen by raising or lowering the member D, the effect of which is either to press the nibs F F of the pen closer together or allow them to spread apart. The operation will be obvious. The ink is supplied from the barrel A, filling the extension B, from whence it flows mto the aperture 6 and'feeding-tube E mtolthe nibs of the pen F F. To regulate the wldth of line to be drawn, the member D is pushed a short distance under the collar C, which operation will press the nibs of the pen closer together, giving afine line, or if the member D is slightly lowered the ressure on the nibs of the pen is released an the distance between the points thereof is increased unt1l the width of line desired is obtained.

The advantages of my invention w1ll be apparent to those skilled in the art. My mprovements are very simple in constructlon, comprise few parts, can be easily and cheaply manufactured and placed in position, and are effectual in all respects in the performance of their functions.

Slight changes might be made in the details of construction of my invention wlthout departing from the spirit thereof or llmitmg the scope, and hence I do not wish to limit myself to the precise details of construction herein shown; but I contemplate such changes as, for instance, instead of provlding the extension B the barrel A might be provided with the annular shoulders I) b b and the other parts adapted thereto, as shown. Instead of holding the member D in position by friction the same might be screw-threaded onto the extension or ink-barrel. I claim 1. In a fountain-pen, the combination of an ink-barrel, an annular member ad ustably secured to said ink-barrel, pen-nibs adjustably secured inside of said annular member, and a feeding-tube inside of said nibs, substantially as described.

2. In a fountain-pen, the combination of an ink-barrel gwithfafconical-shaped member secured to the lower portion thereof, the nibs of a pen supported inside of said conicalshaped mem er, and an ink-feeding tube inside of said nibs, substantially as described.

3. In a fountain-pen, the combination of an ink-barrel, a tubular extension secured to said ink-barrel, an annular member, a collar adapted to hold said extension and annular member in frictional contact, pen-nibs adjustably secured in said annular member and a feeding-tube inside of said nibs, substantially as described.

4. In a fountain-pen, the combination of an ink-barrel, an annular member adjustably secured to said ink-barrel, a feeding-tube inside of said annular member, said feeding tube having recesses in the head thereof, the upper ends of the nibs of a pen extending into said recesses, and means for laterally adjusting said. pen-nibs, substantially as described.

5. In a fountain-pen, the combination of an ink-barrel, an extension removably secured to said ink-barrel, an annular member removably secured to said extension, a tubular stem supported in said annular member, said stem having recesses in the head thereof, the nibs of a pen disposed within said annular member, the upper ends of said nibs extending into the aforesaid recesses, and the lower ends thereof projecting through the end of said annular member, substantially as described.

In testimony whereof I have hereunto signed the foregoing specification in the presence of two subscribing Witnesses.

ALFRED HALL.
