UNITED STATES PATENT OFFICE.
JOHN BLAIR, OF BROOKLYN, NEIV YORK.
FOUNTAIN-PEN.
SPECIFICATION forming part of Letters Patent No. 468,322, dated February 9, 1892. Appiication filed November 14, 1891. Serial No. 411,881. (No model.)
To aZ whom it may concern.-
Be it known that I, JOHN BLAIR, a subject of the Queen of Great Britain, residing at Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Fountain-Pens; and I do declare the following to be a full, clear, and we act description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being bad to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.
My invention relates to writing-pens in which a supply of ink is stored in the penholder and made to flow out upon the penpoint in the act of Writing. In some of these fountain-pens the feed-bar and pen-point are removable and may be adjusted in the nozzle to regulate the flow of ink. It is found, however, thatif an ordinary pen-point is pressed into the nozzle beyond a certain place its normal curve and the set of its tips are disturbed by the pressure against the sides of the nozzle, and the pen either scratches or otherwise writes badly. My invention overcomes this difficulty by the devices described below.
Another improvement in my fountain-pen is found in the formation of an angular rim around the open end of the cap to serve certain purposes hereinafter explained.
The accompanying drawings set forth the invention, the various features of which are referred to by letters, similar letters denoting corresponding parts in the different views.
In the drawings, Figure 1 is a full-length view of theinvention, partlyin section. Fig. 2 is a profile of the feed-bar enlarged, and Fig. 3 is a view of the open end of the cap.
The letter A indicates the body or barrel of the pen having the threaded portion a, into which is screwed the threaded end 79 of the nozzle B. An angulargroove c is cut around the inner surface of this nozzle 13 toward its rear end, the deeper side of the goove to- Ward the rear.
D is the feed-bar, having the point (Z and a recess e in which the heel of the pen g rests. The rear end or butt of the feed-bar D is wedge-shaped and formed into prongs z' 2', which have a springy quality and diverge slightly from each other.
To adjust the parts together, the pen-point is placed in the recess (2 of the bar, and the prongs t' 2 are compressed suliiciently to allow them to enter the front of the nozzle. The bar is then pushed into the nozzle until the prongs 2' 1' spring into the groove 0, by which it is stopped. The groove is formed at a point where it will stop an ordinary gold pen before its wider portion is forced into the narrow opening of the nozzle. The angular rim h on the cap II prevents the rolling of the pen when laid upon an inclined surface, and insures it against falling out when carried in the pocket.
Having now described my invention, what I claim is 1. In a fountain-pen, a feed-bar having a wed ge-shaped elastic base with prongs adapted to engage a groove in the nozzle, as herein described.
2. In a fountain-pen, a nozzle B, having a groove 0 formed in its inner side to receive the prongs of the feed-bar, as described.
3. In a fountain-pen having a removable feed-bar and adapted to use an ordinary pen, a longitudinal recess in said bar to receive the pen and a flattened elastic forked rear end on said bar adapted to spring into an angular groove in the nozzle, as herein described.
l. Afountain-penhavingabodyA, threaded ate, a nozzle B, threaded at b and adapted to screw into the bodyA, a groove 0 in said nozzle, a feed-bar I), having the point d and penrecess 6, and an elastic base having prongst' t to engage the groove 0 in the nozzle, and a cap H, having an angular rim 71, substantially as herein set forth.
In testimony whereofI aliix my signature in presence of two witnesses.
