STYLUGRAPHIG FOUNTAIN PEN.
N. PETERS, Phckuljlhngnphur. Washington. ac.
" UNITED STATES EDWIN W. MORTON, OF WHITE PLAINS, NEW YORK.
-STYLOGRAPH|C PATENT OFFICE.
FOUNTAIN-PEN.
SPECIFICATION forming part of Letters Patent No. 277,149, dated May 8, 1883. Application filed August 28, 1882. (No model.)
To all whom it may concern: Y
Be it known that I, EDWIN W. MORTON, residing at White Plains, in the county of Westchester and State of New York, have invented ,an Improvement in Stylographic Fountain- Pens, of which the followiugis a specification.
The object of my invention is to provide a point for fountain-pens that may be extended as itwears away.
The nature of my invention consists in providing a cushion or spring composed of soft rubber or other similar material inclosed in a cap or short tube placed on the lower end of the air-tube, which gives a. certain amount of elasticity to the writing-point, and by its vibratory movement prevents the ink from drying in the tube near the point.
My invention also consists in loosely screwiugthe air-tube in the upper part of the pen, and enlarging the air-tube near the screw, so as to fit tightly in a'corresponding-sized bore in the top of the pen.
Figure 1 represents the exterior of thepeu when closed for carrying in the pocket. Fig. 2 is a longitudinal sectional view. Fig. 3 is an enlarged longitudinal section of the point-section of. the pen. Fig.4 is a transverse section takenin the line :20 a: of Fig. 3, it being very much enlarged to clearly show the form of the needle or writing point.
Similar'letters refer to similar parts throughout the several views.
In the accompanying drawings, A is the inkreservoir, preferably made of hard rubber or other similar non-corrosive material.
B is the vent-ca G is the point-section; D, the point-cover; E, the air-tube; F, the needle or writingpoiut, and G the rubber spring or cushion.
The needle F is of one size throughout, and has cut in its lower end one or more flutes or grooves, ,a, five being preferred, as shown clearly in Fig. 4, said grooves to conduct the ink from the tube 1) down to the paper, the difference in the size of the needle above thegrooves and the size of the bore in the metal tube 1) being just sufficient to properly govern the supply of ink. The upper end of the needle F is enlarged to form a. head, 0, which rests against the rubber spring or cushion G,
A hole, h, is bored in the upper part of the ink-reservoir A of such a size that the piston g will just enter and be able to pass through said bore, but tight enough to make an airtightjoiut. The upper part of the bore h is cut interiorly with ascrew-thread to engage loosely the'corresponding screw,f, on the air-tube E. Thus by removing the air-cap B and turning the air-tube E by the knurled head i the airtube E, carryingthe needle F, can be screwed in or out to properly adjust the distance that the end of the needle F projects from the end ofthe tube 1), so that the pressure of writing will not force the needle up far enough to allow the end of the tube 1) to touch the paper, and also to extend the needle F as it wears away, thus keeping the writingpoint always the same until it is entirely worn out,wheu It may easily be replaced by a new one by simply removing the cap e and dropping out the rubber cushion G. The fluted end of the needle may also be tipped with iridium, to more effectually prevent wear.
I claim as my invention-- 1. In a fountain-pen, the combination of the fluted needle F, provided with an enlargement or head, 0, the rubber cushion G, and cap'e, attached to the tube E, as herein described and shown, and for the purpose set forth.
2. In a fountain-pen, the combination of the air-tube E, provided with a loosely-fitting screw,f, and the piston g, fitting tightlyin the bore h, as herein shown and described, and for the purpose set forth.
