JOHN HOLLAND, OF CINCINNATI, OHIO.

STYLOGRAPHIC FOUNTAIN-PEN.

SPECIFICATION forming part of Letters Patent No. 275,912', dated April 1'7, 1883.

Application led October 11, 188i. (No model.)

To all whom it may concern:

Be it known that l, JOHN HOLLAND, of the city of Cincinnati, county of Hamilton, State of Ohio, have invented certain new and useful Improvements in Stylographic Fountain- Pens, of which the following is a specification.

This invention relates to that class of writing-instruments in which the handle serves as areservoirforink,theowofwhichiscontrolled by a needle protruding through the writingpoint.

The objects of the invention are to provide a convenient means for adjust-ing the needle, and to insure a regular tlow of the ink when in use.

The invention will be first fully described, referring to the accompanying drawings, and particularly pointed out in the claims.

Figure l is a central vertical sectional view of the lower part of a pen containing my improvements, the upper portion ofthe pen,which is common and in general use, being shown in elevation. Fig. 2 is a central vertical section of the needle-holder and its attachments. Fig. 3 is a perspective view ofthe needle and needie-holder.

Similar reference-letters indicate the same parts wherever they occur.

The holder A, air-tube B, point-section D, and vent-cap C are the same as those in common use, and need no particular description here.

The point-section D has an internal screwthread to receive a thread upon the needleholder E. The needle-holder is a tube, preferably of hard rubber, the upper end being open to receive the lower end of the air-tube B. The lower end of needle-holder E has a central perforation, through which the spindle or needle F protrudes. The needle has an enlargement or head within the tube E, between which and the screw-plug gis compressed a spiral spring,f. On the exterior of tube E, near the top, is a collar, e', which is screwthreaded to engage the screw-thread within the point-section. By this means the needle is adjusted in the writing-point. A burr, e, at the top of the holder E is for convenience in turning the holder to protrude or retract the needle with relation to t'ne writing point.

Through the collar c and burr c are channels e2, to admit ink from the handle A into the point-section D around the diminished lower end of the needle-holder E. Transverse perforations I in the lower end of needle-holder E admit air t'rom tube B to the point-section D. By this means I am enabled to admit the air nearer the writing-point, which insures a more uniform flow of ink in use and prevents leakage when not in use. By my arrangement of the adjustable needle-holder in the pointsection I am enabled to readily adjust the needle with relation to the writing with great nicety, and in case the needle sticks or clogs with ink it is easily freed by moving it back and forth through its holder' E. While I have shown a screw-joint between the point-section and needle-holder, as it allows of more accurately adjusting the needle-valve, a frictionA joint could be made to answer the purpose. rlhe holder E is separable by a joint at h, to afford access to the screw-plug g to loosen or compress the springf when desired.

It will be seen that in my pen the needlepoint is readily adjustable to suit the hand of the writer For instance, if the writers habit is to hold a pen perpendicularly, or nearly so, the point is retracted, so as to leave but a small portion of it protruding through the writingpoint; or, if it is desired to write with the holder much inclined, the needle is protruded farther to insure the opening of the valve. Again, some writers desire a hard77 point, like apencil, in writing, while others require some elasticity or spring, like the common pen. My pen can be readily adapted to the hand of either. If the hard touch is required, the plug g is unscrewed to slacken the springf, so that the needle will be pushed back in writing without appreciable pressure. If the plug g is driven down and the spring compressed hard between the head of the needle and' plug, the pressure ofthe spring will be plainly felt in writing.

I claiml. The combination, substantially as before set forth, of the handle A, the point-section D, and the holder E, carrying the spring-pressed needle, and extending above the point-section, to afford a convenient means to adjust the nee- I, and the air-tube B, the perforated lower v end of which extends within the needle-holder.
