CHARLES IVOODBURY ROBINSON, OF LONDON, ENGLAND.
STYLOG RAPH IC PEN.
SPECIFICATION forming part of Letters Patent No. 443,542, dated December 80, 1890.
Application filed June 24, 1890. Serial No. 356,559. (No model.)
To all whom. it may concern:
Beit known that I, CHARLES VVOODBURY ROBINSON, of 16 I-Iolborn, London, England, a subject of the Queen of Great Britain and Ireland, have invented an Improvement in Holders for Reservoir Fountain Pens, of which the following is a specification.
This invention relates to improvements in stylographic or fountain pens, and has for its object means for starting or feeding a small quantity of ink to the stylograph before commencing to write. For this purpose the tube forming the ink-reservoir is itted at the end farthest from the stylograph with 'a plug formed of soft rubber, cork, or other similar elastic material. This plug is formed with a central recess into which-fits tightly an inner central air-tube, which may also be fitted with another smaller air-tube, tothe outer end of which is fixed, by means of a small elastic tube, the stylographic writing point or needle. The recess in the elastic plug forms an air-space to which air may be fed by means of a minute hole or passage leading therefrom to the outer end of the plug. A part of the plug containing the upper portion of the recess before mentioned projects beyond the reservoir-tube to which it is fitted, and when it is required to use the pen the sheath or cover forming a protector to the needle-point is removed therefrom and fixed over the projecting end of the plug. The'operation of fixing the sheath or cover upon the projecting end of this elastic plug compresses the air Within the air-space which is continued beyond the outside tube and forces the air along the air-tube and out through. a small hole near the end of the small tube. The air passing through this hole starts or forces a small quantity of ink to the needle-point and thus prepares the pen for immediate use.
` In order that my said invention may be more fully understood, I will describe the same with reference to the accompanying sheet of drawings, in Which- Figure 1 is a longitudinal section of my improved pen. Fig. 2 is an outside view thereof. Fig. 3 is an enlarged section of the plug with a portion of the reservoir and airtubes, and Fig. 4. is a cross-section through line A. B of Fig. 3.
a is the outer tube, forming the reservoirink.
nected, by means of the small rubber tube 71,
the needle-point t'.
K is the sheath or cover which protects the needle-point when the pen is not in use, but l which, when the pen is required for writing, is fixed over the projecting end of the plug Cl. As the sheath K is forced or screwed on the end of the plug, it compresses the latter and forces the air from the recess e along the tube f and out vthrough a perforation t at the end of the tube g, thus forcing or feeding the ink to the needle-point to start a flow of In some forms the tube g may be dispensed with, the tube 7L, which should be formed of the best black rubber, being'tted to the end of the tube f, and is the means of giving the necessary resiliency to the needle. A small perforation m leads from the recess c to the outer end of the plug, and the sheath may be likewise perforated at n for admittance of air to the plug. rlhe tube a is filled with ink by removing the plug (L.
Having now fully described and ascertained the nature of my said invention and in what manner the same is to be performed, I declare that what I claim is In a fountain-pen, the elastic plug d, formed with air-space c and perforation m,iitted into the end ot' the reservoir-tube in such a manner that the upper port-ion of the air-recess c projects beyond the end of the said tube, substantially as before described in this specification and illustrated by the accompanying drawings, for the purpose of starting a minute supply of ink to the pen-point.
In testimony whereof I sign this specification in the presence of two subscribing witnesses.
CHARLES WOODBURY ROBINSON.
